-# CMakeLists.txt
-#
-# This file enables PCRE2 to be built with the CMake configuration and build
-# tool. Download CMake in source or binary form from http://www.cmake.org/
-# Converted to support PCRE2 from the original PCRE file, August 2014.
-#
-# Original listfile by Christian Ehrlicher <Ch.Ehrlicher@gmx.de>
-# Refined and expanded by Daniel Richard G. <skunk@iSKUNK.ORG>
-# 2007-09-14 mod by Sheri so 7.4 supported configuration options can be entered
-# 2007-09-19 Adjusted by PH to retain previous default settings
-# 2007-12-26 (a) On UNIX, use names libpcre instead of just pcre
-#            (b) Ensure pcretest and pcregrep link with the local library,
-#                not a previously-installed one.
-#            (c) Add PCRE_SUPPORT_LIBREADLINE, PCRE_SUPPORT_LIBZ, and
-#                PCRE_SUPPORT_LIBBZ2.
-# 2008-01-20 Brought up to date to include several new features by Christian
-#            Ehrlicher.
-# 2008-01-22 Sheri added options for backward compatibility of library names
-#            when building with minGW:
-#            if "ON", NON_STANDARD_LIB_PREFIX causes shared libraries to
-#            be built without "lib" as prefix. (The libraries will be named
-#            pcre.dll, pcreposix.dll and pcrecpp.dll).
-#            if "ON", NON_STANDARD_LIB_SUFFIX causes shared libraries to
-#            be built with suffix of "-0.dll". (The libraries will be named
-#            libpcre-0.dll, libpcreposix-0.dll and libpcrecpp-0.dll - same names
-#            built by default with Configure and Make.
-# 2008-01-23 PH removed the automatic build of pcredemo.
-# 2008-04-22 PH modified READLINE support so it finds NCURSES when needed.
-# 2008-07-03 PH updated for revised UCP property support (change of files)
-# 2009-03-23 PH applied Steven Van Ingelgem's patch to change the name
-#            CMAKE_BINARY_DIR to PROJECT_BINARY_DIR so that it works when PCRE
-#            is included within another project.
-# 2009-03-23 PH applied a modified version of Steven Van Ingelgem's patches to
-#            add options to stop the building of pcregrep and the tests, and
-#            to disable the final configuration report.
-# 2009-04-11 PH applied Christian Ehrlicher's patch to show compiler flags that
-#            are set by specifying a release type.
-# 2010-01-02 PH added test for stdint.h
-# 2010-03-02 PH added test for inttypes.h
-# 2011-08-01 PH added PCREGREP_BUFSIZE
-# 2011-08-22 PH added PCRE_SUPPORT_JIT
-# 2011-09-06 PH modified WIN32 ADD_TEST line as suggested by Sergey Cherepanov
-# 2011-09-06 PH added PCRE_SUPPORT_PCREGREP_JIT
-# 2011-10-04 Sheri added support for including coff data in windows shared libraries
-#            compiled with MINGW if pcre.rc and/or pcreposix.rc are placed in
-#            the source dir by the user prior to building
-# 2011-10-04 Sheri changed various add_test's to use exes' location built instead
-#            of DEBUG location only (likely only matters in MSVC)
-# 2011-10-04 Sheri added scripts to provide needed variables to RunTest and
-#            RunGrepTest (used for UNIX and Msys)
-# 2011-10-04 Sheri added scripts to provide needed variables and to execute
-#            RunTest.bat in Win32 (for effortless testing with "make test")
-# 2011-10-04 Sheri Increased minimum required cmake version
-# 2012-01-06 PH removed pcre_info.c and added pcre_string_utils.c
-# 2012-01-10 Zoltan Herczeg added libpcre16 support
-# 2012-01-13 Stephen Kelly added out of source build support
-# 2012-01-17 PH applied Stephen Kelly's patch to parse the version data out
-#            of the configure.ac file
-# 2012-02-26 PH added support for libedit

-# 2012-12-08 PH added patch from Daniel Richard G to quash some MSVC warnings
-# 2013-07-01 PH realized that the "support" for GCOV was a total nonsense and
-#            so it has been removed.
-# 2013-10-08 PH got rid of the "source" command, which is a bash-ism (use ".")
-# 2013-11-05 PH added support for PARENS_NEST_LIMIT
-# 2014-08-29 PH converted the file for PCRE2 (which has no C++).
-# 2015-04-24 PH added support for PCRE2_DEBUG
-# 2015-07-16 PH updated for new pcre2_find_bracket source module

-# 2016-03-01 PH applied Chris Wilson's patch for MSVC static
-# 2016-06-24 PH applied Chris Wilson's second patch, putting the first under
-#            a new option instead of being unconditional.
-# 2016-10-05 PH fixed a typo (PCRE should be PCRE2) in above patch

-Change Log for PCRE2
---------------------
-
-
-Version 10.37 26-May-2021
--------------------------
-
-1. Change RunGrepTest to use tr instead of sed when testing with binary
-zero bytes, because sed varies a lot from system to system and has problems
-with binary zeros. This is from Bugzilla #2681. Patch from Jeremie
-Courreges-Anglas via Nam Nguyen. This fixes RunGrepTest for OpenBSD. Later:
-it broke it for at least one version of Solaris, where tr can't handle binary
-zeros. However, that system had /usr/xpg4/bin/tr installed, which works OK, so
-RunGrepTest now checks for that command and uses it if found.
-
-2. Compiling with gcc 10.2's -fanalyzer option showed up a hypothetical problem
-with a NULL dereference. I don't think this case could ever occur in practice,
-but I have put in a check in order to get rid of the compiler error.
-
-3. An alternative patch for CMakeLists.txt because 10.36 #4 breaks CMake on
-Windows. Patch from email@cs-ware.de fixes bugzilla #2688.
-
-4. Two bugs related to over-large numbers have been fixed so the behaviour is
-now the same as Perl.
-
-  (a) A pattern such as /\214748364/ gave an overflow error instead of being
-  treated as the octal number \214 followed by literal digits.
-
-  (b) A sequence such as {65536 that has no terminating } so is not a
-  quantifier was nevertheless complaining that a quantifier number was too big.
-
-5. A run of autoconf suggested that configure.ac was out-of-date with respect
-to the lastest autoconf. Running autoupdate made some valid changes, some valid
-suggestions, and also some invalid changes, which were fixed by hand. Autoconf
-now runs clean and the resulting "configure" seems to work, so I hope nothing
-is broken. Later: the requirement for autoconf 2.70 broke some automatic test
-robots. It doesn't seem to be necessary: trying a reduction to 2.60.
-
-6. The pattern /a\K.(?0)*/ when matched against "abac" by the interpreter gave
-the answer "bac", whereas Perl and JIT both yield "c". This was because the
-effect of \K was not propagating back from the full pattern recursion. Other
-recursions such as /(a\K.(?1)*)/ did not have this problem.
-
-7. Restore single character repetition optimization in JIT. Currently fewer
-character repetitions are optimized than in 10.34.
-
-8. When the names of the functions in the POSIX wrapper were changed to
-pcre2_regcomp() etc. (see change 10.33 #4 below), functions with the original
-names were left in the library so that pre-compiled programs would still work.
-However, this has proved troublesome when programs link with several libraries,
-some of which use PCRE2 via the POSIX interface while others use a native POSIX
-library. For this reason, the POSIX function names are removed in this release.
-The macros in pcre2posix.h should ensure that re-compiling fixes any programs
-that haven't been compiled since before 10.33.
-
-
-Version 10.36 04-December-2020
-------------------------------
-
-1. Add CET_CFLAGS so that when Intel CET is enabled, pass -mshstk to
-compiler. This fixes https://bugs.exim.org/show_bug.cgi?id=2578. Patch for
-Makefile.am and configure.ac by H.J. Lu. Equivalent patch for CMakeLists.txt
-invented by PH.
-
-2. Fix inifinite loop when a single byte newline is searched in JIT when
-invalid utf8 mode is enabled.
-
-3. Updated CMakeLists.txt with patch from Wolfgang Stöggl (Bugzilla #2584):
-
-  - Include GNUInstallDirs and use ${CMAKE_INSTALL_LIBDIR} instead of hardcoded
-    lib. This allows differentiation between lib and lib64.
-    CMAKE_INSTALL_LIBDIR is used for installation of libraries and also for
-    pkgconfig file generation.
-
-  - Add the version of PCRE2 to the configuration summary like ./configure
-    does.
-
-  - Fix typo: MACTHED_STRING->MATCHED_STRING
-
-4. Updated CMakeLists.txt with another patch from Wolfgang Stöggl (Bugzilla
-#2588):
-
-  - Add escaped double quotes around include directory in CMakeLists.txt to
-    allow spaces in directory names.
-
-  - This fixes a cmake error, if the path of the pcre2 source contains a space.
-
-5. Updated CMakeLists.txt with a patch from B. Scott Michel: CMake's
-documentation suggests using CHECK_SYMBOL_EXISTS over CHECK_FUNCTION_EXIST.
-Moreover, these functions come from specific header files, which need to be
-specified (and, thankfully, are the same on both the Linux and WinXX
-platforms.)
-
-6. Added a (uint32_t) cast to prevent a compiler warning in pcre2_compile.c.
-
-7. Applied a patch from Wolfgang Stöggl (Bugzilla #2600) to fix postfix for
-debug Windows builds using CMake. This also updated configure so that it
-generates *.pc files and pcre2-config with the same content, as in the past.
-
-8. If a pattern ended with (?(VERSION=n.d where n is any number but d is just a
-single digit, the code unit beyond d was being read (i.e. there was a read
-buffer overflow). Fixes ClusterFuzz 23779.
-
-9. After the rework in r1235, certain character ranges were incorrectly
-handled by an optimization in JIT. Furthermore a wrong offset was used to
-read a value from a buffer which could lead to memory overread.
-
-10. Unnoticed for many years was the fact that delimiters other than / in the
-testinput1 and testinput4 files could cause incorrect behaviour when these
-files were processed by perltest.sh. There were several tests that used quotes
-as delimiters, and it was just luck that they didn't go wrong with perltest.sh.
-All the patterns in testinput1 and testinput4 now use / as their delimiter.
-This fixes Bugzilla #2641.
-
-11. Perl has started to give an error for \K within lookarounds (though there
-are cases where it doesn't). PCRE2 still allows this, so the tests that include
-this case have been moved from test 1 to test 2.
-
-12. Further to 10 above, pcre2test has been updated to detect and grumble if a
-delimiter other than / is used after #perltest.
-
-13. Fixed a bug with PCRE2_MATCH_INVALID_UTF in 8-bit mode when PCRE2_CASELESS
-was set and PCRE2_NO_START_OPTIMIZE was not set. The optimization for finding
-the start of a match was not resetting correctly after a failed match on the
-first valid fragment of the subject, possibly causing incorrect "no match"
-returns on subsequent fragments. For example, the pattern /A/ failed to match
-the subject \xe5A. Fixes Bugzilla #2642.
-
-14. Fixed a bug in character set matching when JIT is enabled and both unicode
-scripts and unicode classes are present at the same time.
-
-15. Added GNU grep's -m (aka --max-count) option to pcre2grep.
-
-16. Refactored substitution processing in pcre2grep strings, both for the -O
-option and when dealing with callouts. There is now a single function that
-handles $ expansion in all cases (instead of multiple copies of almost
-identical code). This means that the same escape sequences are available
-everywhere, which was not previously the case. At the same time, the escape
-sequences $x{...} and $o{...} have been introduced, to allow for characters
-whose code points are greater than 255 in Unicode mode.
-
-17. Applied the patch from Bugzilla #2628 to RunGrepTest. This does an explicit
-test for a version of sed that can handle binary zero, instead of assuming that
-any Linux version will work. Later: replaced $(...) by `...` because not all
-shells recognize the former.
-
-18. Fixed a word boundary check bug in JIT when partial matching is enabled.
-
-19. Fix ARM64 compilation warning in JIT. Patch by Carlo.
-
-20. A bug in the RunTest script meant that if the first part of test 2 failed,
-the failure was not reported.
-
-21. Test 2 was failing when run from a directory other than the source
-directory. This failure was previously missed in RunTest because of 20 above.
-Fixes added to both RunTest and RunTest.bat.
-
-22. Patch to CMakeLists.txt from Daniel to fix problem with testing under
-Windows.
-
-
-Version 10.35 09-May-2020
----------------------------
-
-1. Use PCRE2_MATCH_EMPTY flag to detect empty matches in JIT.
-
-2. Fix ARMv5 JIT improper handling of labels right after a constant pool.
-
-3. A JIT bug is fixed which allowed to read the fields of the compiled
-pattern before its existence is checked.
-
-4. Back in the PCRE1 day, capturing groups that contained recursive back
-references to themselves were made atomic (version 8.01, change 18) because
-after the end a repeated group, the captured substrings had their values from
-the final repetition, not from an earlier repetition that might be the
-destination of a backtrack. This feature was documented, and was carried over
-into PCRE2. However, it has now been realized that the major refactoring that
-was done for 10.30 has made this atomicizing unnecessary, and it is confusing
-when users are unaware of it, making some patterns appear not to be working as
-expected. Capture values of recursive back references in repeated groups are
-now correctly backtracked, so this unnecessary restriction has been removed.
-
-5. Added PCRE2_SUBSTITUTE_LITERAL.
-
-6. Avoid some VS compiler warnings.
-
-7. Added PCRE2_SUBSTITUTE_MATCHED.
-
-8. Added (?* and (?<* as synonms for (*napla: and (*naplb: to match another
-regex engine. The Perl regex folks are aware of this usage and have made a note
-about it.
-
-9. When an assertion is repeated, PCRE2 used to limit the maximum repetition to
-1, believing that repeating an assertion is pointless. However, if a positive
-assertion contains capturing groups, repetition can be useful. In any case, an
-assertion could always be wrapped in a repeated group. The only restriction
-that is now imposed is that an unlimited maximum is changed to one more than
-the minimum.
-
-10. Fix *THEN verbs in lookahead assertions in JIT.
-
-11. Added PCRE2_SUBSTITUTE_REPLACEMENT_ONLY.
-
-12. The JIT stack should be freed when the low-level stack allocation fails.
-
-13. In pcre2grep, if the final line in a scanned file is output but does not
-end with a newline sequence, add a newline according to the --newline setting.
-
-14. (?(DEFINE)...) groups were not being handled correctly when checking for
-the fixed length of a lookbehind assertion. Such a group within a lookbehind
-should be skipped, as it does not contribute to the length of the group.
-Instead, the (DEFINE) group was being processed, and if at the end of the
-lookbehind, that end was not correctly recognized. Errors such as "lookbehind
-assertion is not fixed length" and also "internal error: bad code value in
-parsed_skip()" could result.
-
-15. Put a limit of 1000 on recursive calls in pcre2_study() when searching
-nested groups for starting code units, in order to avoid stack overflow issues.
-If the limit is reached, it just gives up trying for this optimization.
-
-16. The control verb chain list must always be restored when exiting from a
-recurse function in JIT.
-
-17. Fix a crash which occurs when the character type of an invalid UTF
-character is decoded in JIT.
-
-18. Changes in many areas of the code so that when Unicode is supported and
-PCRE2_UCP is set without PCRE2_UTF, Unicode character properties are used for
-upper/lower case computations on characters whose code points are greater than
-127.
-
-19. The function for checking UTF-16 validity was returning an incorrect offset
-for the start of the error when a high surrogate was not followed by a valid
-low surrogate. This caused incorrect behaviour, for example when
-PCRE2_MATCH_INVALID_UTF was set and a match started immediately following the
-invalid high surrogate, such as /aa/ matching "\x{d800}aa".
-
-20. If a DEFINE group immediately preceded a lookbehind assertion, the pattern
-could be mis-compiled and therefore not match correctly. This is the example
-that found this: /(?(DEFINE)(?<foo>bar))(?<![-a-z0-9])word/ which failed to
-match "word" because the "move back" value was set to zero.
-
-21. Following a request from a user, some extensions and tidies to the
-character tables handling have been done:
-
-  (a) The dftables auxiliary program is renamed pcre2_dftables, but it is still
-  not installed for public use.
-
-  (b) There is now a -b option for pcre2_dftables, which causes the tables to
-  be written in binary. There is also a -help option.
-
-  (c) PCRE2_CONFIG_TABLES_LENGTH is added to pcre2_config() so that an
-  application that wants to save tables in binary knows how long they are.
-
-22. Changed setting of CMAKE_MODULE_PATH in CMakeLists.txt from SET to
-LIST(APPEND...) to allow a setting from the command line to be included.
-
-23. Updated to Unicode 13.0.0.
-
-24. CMake build now checks for secure_getenv() and strerror(). Patch by Carlo.
-
-25. Avoid using [-1] as a suffix in pcre2test because it can provoke a compiler
-warning.
-
-26. Added tests for __attribute__((uninitialized)) to both the configure and
-CMake build files, and then applied this attribute to the variable called
-stack_frames_vector[] in pcre2_match(). When implemented, this disables
-automatic initialization (a facility in clang), which can take time on big
-variables.
-
-27. Updated CMakeLists.txt (patches by Uwe Korn) to add support for
-pcre2-config, the libpcre*.pc files, SOVERSION, VERSION and the
-MACHO_*_VERSIONS settings for CMake builds.
-
-28. Another patch to CMakeLists.txt to check for mkostemp (configure already
-does). Patch by Carlo Marcelo Arenas Belon.
-
-29. Check for the existence of memfd_create in both CMake and configure
-configurations. Patch by Carlo Marcelo Arenas Belon.
-
-30. Restrict the configuration setting for the SELinux compatible execmem
-allocator (change 10.30/44) to Linux and NetBSD.
-
-
-Version 10.34 21-November-2019
-------------------------------
-
-1. The maximum number of capturing subpatterns is 65535 (documented), but no
-check on this was ever implemented. This omission has been rectified; it fixes
-ClusterFuzz 14376.
-
-2. Improved the invalid utf32 support of the JIT compiler. Now it correctly
-detects invalid characters in the 0xd800-0xdfff range.
-
-3. Fix minor typo bug in JIT compile when \X is used in a non-UTF string.
-
-4. Add support for matching in invalid UTF strings to the pcre2_match()
-interpreter, and integrate with the existing JIT support via the new
-PCRE2_MATCH_INVALID_UTF compile-time option.
-
-5. Give more error detail for invalid UTF-8 when detected in pcre2grep.
-
-6. Add support for invalid UTF-8 to pcre2grep.
-
-7. Adjust the limit for "must have" code unit searching, in particular,
-increase it substantially for non-anchored patterns.
-
-8. Allow (*ACCEPT) to be quantified, because an ungreedy quantifier with a zero
-minimum is potentially useful.
-
-9. Some changes to the way the minimum subject length is handled:
-
-   * When PCRE2_NO_START_OPTIMIZE is set, no minimum length is computed;
-     pcre2test now omits this item instead of showing a value of zero.
-
-   * An incorrect minimum length could be calculated for a pattern that
-     contained (*ACCEPT) inside a qualified group whose minimum repetition was
-     zero, for example /A(?:(*ACCEPT))?B/, which incorrectly computed a minimum
-     of 2. The minimum length scan no longer happens for a pattern that
-     contains (*ACCEPT).
-
-   * When no minimum length is set by the normal scan, but a first and/or last
-     code unit is recorded, set the minimum to 1 or 2 as appropriate.
-
-   * When a pattern contains multiple groups with the same number, a back
-     reference cannot know which one to scan for a minimum length. This used to
-     cause the minimum length finder to give up with no result. Now it treats
-     such references as not adding to the minimum length (which it should have
-     done all along).
-
-   * Furthermore, the above action now happens only if the back reference is to
-     a group that exists more than once in a pattern instead of any back
-     reference in a pattern with duplicate numbers.
-
-10. A (*MARK) value inside a successful condition was not being returned by the
-interpretive matcher (it was returned by JIT). This bug has been mended.
-
-11. A bug in pcre2grep meant that -o without an argument (or -o0) didn't work
-if the pattern had more than 32 capturing parentheses. This is fixed. In
-addition (a) the default limit for groups requested by -o<n> has been raised to
-50, (b) the new --om-capture option changes the limit, (c) an error is raised
-if -o asks for a group that is above the limit.
-
-12. The quantifier {1} was always being ignored, but this is incorrect when it
-is made possessive and applied to an item in parentheses, because a
-parenthesized item may contain multiple branches or other backtracking points,
-for example /(a|ab){1}+c/ or /(a+){1}+a/.
-
-13. For partial matches, pcre2test was always showing the maximum lookbehind
-characters, flagged with "<", which is misleading when the lookbehind didn't
-actually look behind the start (because it was later in the pattern). Showing
-all consulted preceding characters for partial matches is now controlled by the
-existing "allusedtext" modifier and, as for complete matches, this facility is
-available only for non-JIT matching, because JIT does not maintain the first
-and last consulted characters.
-
-14. DFA matching (using pcre2_dfa_match()) was not recognising a partial match
-if the end of the subject was encountered in a lookahead (conditional or
-otherwise), an atomic group, or a recursion.
-
-15. Give error if pcre2test -t, -T, -tm or -TM is given an argument of zero.
-
-16. Check for integer overflow when computing lookbehind lengths. Fixes
-Clusterfuzz issue 15636.
-
-17. Implemented non-atomic positive lookaround assertions.
-
-18. If a lookbehind contained a lookahead that contained another lookbehind
-within it, the nested lookbehind was not correctly processed. For example, if
-/(?<=(?=(?<=a)))b/ was matched to "ab" it gave no match instead of matching
-"b".
-
-19. Implemented pcre2_get_match_data_size().
-
-20. Two alterations to partial matching:
-
-    (a) The definition of a partial match is slightly changed: if a pattern
-    contains any lookbehinds, an empty partial match may be given, because this
-    is another situation where adding characters to the current subject can
-    lead to a full match. Example: /c*+(?<=[bc])/ with subject "ab".
-
-    (b) Similarly, if a pattern could match an empty string, an empty partial
-    match may be given. Example: /(?![ab]).*/ with subject "ab". This case
-    applies only to PCRE2_PARTIAL_HARD.
-
-    (c) An empty string partial hard match can be returned for \z and \Z as it
-    is documented that they shouldn't match.
-
-21. A branch that started with (*ACCEPT) was not being recognized as one that
-could match an empty string.
-
-22. Corrected pcre2_set_character_tables() tables data type: was const unsigned
-char * instead of const uint8_t *, as generated by pcre2_maketables().
-
-23. Upgraded to Unicode 12.1.0.
-
-24. Add -jitfast command line option to pcre2test (to make all the jit options
-available directly).
-
-25. Make pcre2test -C show if libreadline or libedit is supported.
-
-26. If the length of one branch of a group exceeded 65535 (the maximum value
-that is remembered as a minimum length), the whole group's length was
-incorrectly recorded as 65535, leading to incorrect "no match" when start-up
-optimizations were in force.
-
-27. The "rightmost consulted character" value was not always correct; in
-particular, if a pattern ended with a negative lookahead, characters that were
-inspected in that lookahead were not included.
-
-28. Add the pcre2_maketables_free() function.
-
-29. The start-up optimization that looks for a unique initial matching
-code unit in the interpretive engines uses memchr() in 8-bit mode. When the
-search is caseless, it was doing so inefficiently, which ended up slowing down
-the match drastically when the subject was very long. The revised code (a)
-remembers if one case is not found, so it never repeats the search for that
-case after a bumpalong and (b) when one case has been found, it searches only
-up to that position for an earlier occurrence of the other case. This fix
-applies to both interpretive pcre2_match() and to pcre2_dfa_match().
-
-30. While scanning to find the minimum length of a group, if any branch has
-minimum length zero, there is no need to scan any subsequent branches (a small
-compile-time performance improvement).
-
-31. Installed a .gitignore file on a user's suggestion. When using the svn
-repository with git (through git svn) this helps keep it tidy.
-
-32. Add underflow check in JIT which may occur when the value of subject
-string pointer is close to 0.
-
-33. Arrange for classes such as [Aa] which contain just the two cases of the
-same character, to be treated as a single caseless character. This causes the
-first and required code unit optimizations to kick in where relevant.
-
-34. Improve the bitmap of starting bytes for positive classes that include wide
-characters, but no property types, in UTF-8 mode. Previously, on encountering
-such a class, the bits for all bytes greater than \xc4 were set, thus
-specifying any character with codepoint >= 0x100. Now the only bits that are
-set are for the relevant bytes that start the wide characters. This can give a
-noticeable performance improvement.
-
-35. If the bitmap of starting code units contains only 1 or 2 bits, replace it
-with a single starting code unit (1 bit) or a caseless single starting code
-unit if the two relevant characters are case-partners. This is particularly
-relevant to the 8-bit library, though it applies to all. It can give a
-performance boost for patterns such as [Ww]ord and (word|WORD). However, this
-optimization doesn't happen if there is a "required" code unit of the same
-value (because the search for a "required" code unit starts at the match start
-for non-unique first code unit patterns, but after a unique first code unit,
-and patterns such as a*a need the former action).
-
-36. Small patch to pcre2posix.c to set the erroroffset field to -1 immediately
-after a successful compile, instead of at the start of matching to avoid a
-sanitizer complaint (regexec is supposed to be thread safe).
-
-37. Add NEON vectorization to JIT to speed up matching of first character and
-pairs of characters on ARM64 CPUs.
-
-38. If a non-ASCII character was the first in a starting assertion in a
-caseless match, the "first code unit" optimization did not get the casing
-right, and the assertion failed to match a character in the other case if it
-did not start with the same code unit.
-
-39. Fixed the incorrect computation of jump sizes on x86 CPUs in JIT. A masking
-operation was incorrectly removed in r1136. Reported by Ralf Junker.
-
-
-Version 10.33 16-April-2019
----------------------------
-
-1. Added "allvector" to pcre2test to make it easy to check the part of the
-ovector that shouldn't be changed, in particular after substitute and failed or
-partial matches.
-
-2. Fix subject buffer overread in JIT when UTF is disabled and \X or \R has
-a greater than 1 fixed quantifier. This issue was found by Yunho Kim.
-
-3. Added support for callouts from pcre2_substitute(). After 10.33-RC1, but
-prior to release, fixed a bug that caused a crash if pcre2_substitute() was
-called with a NULL match context.
-
-4. The POSIX functions are now all called pcre2_regcomp() etc., with wrapper
-functions that use the standard POSIX names. However, in pcre2posix.h the POSIX
-names are defined as macros. This should help avoid linking with the wrong
-library in some environments while still exporting the POSIX names for
-pre-existing programs that use them. (The Debian alternative names are also
-defined as macros, but not documented.)
-
-5. Fix an xclass matching issue in JIT.
-
-6. Implement PCRE2_EXTRA_ESCAPED_CR_IS_LF (see Bugzilla 2315).
-
-7. Implement the Perl 5.28 experimental alphabetic names for atomic groups and
-lookaround assertions, for example, (*pla:...) and (*atomic:...). These are
-characterized by a lower case letter following (* and to simplify coding for
-this, the character tables created by pcre2_maketables() were updated to add a
-new "is lower case letter" bit. At the same time, the now unused "is
-hexadecimal digit" bit was removed. The default tables in
-src/pcre2_chartables.c.dist are updated.
-
-8. Implement the new Perl "script run" features (*script_run:...) and
-(*atomic_script_run:...) aka (*sr:...) and (*asr:...).
-
-9. Fixed two typos in change 22 for 10.21, which added special handling for
-ranges such as a-z in EBCDIC environments. The original code probably never
-worked, though there were no bug reports.
-
-10. Implement PCRE2_COPY_MATCHED_SUBJECT for pcre2_match() (including JIT via
-pcre2_match()) and pcre2_dfa_match(), but *not* the pcre2_jit_match() fast
-path. Also, when a match fails, set the subject field in the match data to NULL
-for tidiness - none of the substring extractors should reference this after
-match failure.
-
-11. If a pattern started with a subroutine call that had a quantifier with a
-minimum of zero, an incorrect "match must start with this character" could be
-recorded. Example: /(?&xxx)*ABC(?<xxx>XYZ)/ would (incorrectly) expect 'A' to
-be the first character of a match.
-
-12. The heap limit checking code in pcre2_dfa_match() could suffer from
-overflow if the heap limit was set very large. This could cause incorrect "heap
-limit exceeded" errors.
-
-13. Add "kibibytes" to the heap limit output from pcre2test -C to make the
-units clear.
-
-14. Add a call to pcre2_jit_free_unused_memory() in pcre2grep, for tidiness.
-
-15. Updated the VMS-specific code in pcre2test on the advice of a VMS user.
-
-16. Removed the unnecessary inclusion of stdint.h (or inttypes.h) from
-pcre2_internal.h as it is now included by pcre2.h. Also, change 17 for 10.32
-below was unnecessarily complicated, as inttypes.h is a Standard C header,
-which is defined to be a superset of stdint.h. Instead of conditionally
-including stdint.h or inttypes.h, pcre2.h now unconditionally includes
-inttypes.h. This supports environments that do not have stdint.h but do have
-inttypes.h, which are known to exist. A note in the autotools documentation
-says (November 2018) that there are none known that are the other way round.
-
-17. Added --disable-percent-zt to "configure" (and equivalent to CMake) to
-forcibly disable the use of %zu and %td in formatting strings because there is
-at least one version of VMS that claims to be C99 but does not support these
-modifiers.
-
-18. Added --disable-pcre2grep-callout-fork, which restricts the callout support
-in pcre2grep to the inbuilt echo facility. This may be useful in environments
-that do not support fork().
-
-19. Fix two instances of <= 0 being applied to unsigned integers (the VMS
-compiler complains).
-
-20. Added "fork" support for VMS to pcre2grep, for running an external program
-via a string callout.
-
-21. Improve MAP_JIT flag usage on MacOS. Patch by Rich Siegel.
-
-22. If a pattern started with (*MARK), (*COMMIT), (*PRUNE), (*SKIP), or (*THEN)
-followed by ^ it was not recognized as anchored.
-
-23. The RunGrepTest script used to cut out the test of NUL characters for
-Solaris and MacOS as printf and sed can't handle them. It seems that the *BSD
-systems can't either. I've inverted the test so that only those OS that are
-known to work (currently only Linux) try to run this test.
-
-24. Some tests in RunGrepTest appended to testtrygrep from two different file
-descriptors instead of redirecting stderr to stdout. This worked on Linux, but
-it was reported not to on other systems, causing the tests to fail.
-
-25. In the RunTest script, make the test for stack setting use the same value
-for the stack as it needs for -bigstack.
-
-26. Insert a cast in pcre2_dfa_match.c to suppress a compiler warning.
-
-26. With PCRE2_EXTRA_BAD_ESCAPE_IS_LITERAL set, escape sequences such as \s
-which are valid in character classes, but not as the end of ranges, were being
-treated as literals. An example is [_-\s] (but not [\s-_] because that gave an
-error at the *start* of a range). Now an "invalid range" error is given
-independently of PCRE2_EXTRA_BAD_ESCAPE_IS_LITERAL.
-
-27. Related to 26 above, PCRE2_BAD_ESCAPE_IS_LITERAL was affecting known escape
-sequences such as \eX when they appeared invalidly in a character class. Now
-the option applies only to unrecognized or malformed escape sequences.
-
-28. Fix word boundary in JIT compiler. Patch by Mike Munday.
-
-29. The pcre2_dfa_match() function was incorrectly handling conditional version
-tests such as (?(VERSION>=0)...) when the version test was true. Incorrect
-processing or a crash could result.
-
-30. When PCRE2_UTF is set, allow non-ASCII letters and decimal digits in group
-names, as Perl does. There was a small bug in this new code, found by
-ClusterFuzz 12950, fixed before release.
-
-31. Implemented PCRE2_EXTRA_ALT_BSUX to support ECMAScript 6's \u{hhh}
-construct.
-
-32. Compile \p{Any} to be the same as . in DOTALL mode, so that it benefits
-from auto-anchoring if \p{Any}* starts a pattern.
-
-33. Compile invalid UTF check in JIT test when only pcre32 is enabled.
-
-34. For some time now, CMake has been warning about the setting of policy
-CMP0026 to "OLD" in CmakeLists.txt, and hinting that the feature might be
-removed in a future version. A request for CMake expertise on the list produced
-no result, so I have now hacked CMakeLists.txt along the lines of some changes
-I found on the Internet. The new code no longer needs the policy setting, and
-it appears to work fine on Linux.
-
-35. Setting --enable-jit=auto for an out-of-tree build failed because the
-source directory wasn't in the search path for AC_TRY_COMPILE always. Patch
-from Ross Burton.
-
-36. Disable SSE2 JIT optimizations in x86 CPUs when SSE2 is not available.
-Patch by Guillem Jover.
-
-37. Changed expressions such as 1<<10 to 1u<<10 in many places because compiler
-warnings were reported.
-
-38. Using the clang compiler with sanitizing options causes runtime complaints
-about truncation for statments such as x = ~x when x is an 8-bit value; it
-seems to compute ~x as a 32-bit value. Changing such statements to x = 255 ^ x
-gets rid of the warnings. There were also two missing casts in pcre2test.
-
-
-Version 10.32 10-September-2018
--------------------------------
-
-1. When matching using the the REG_STARTEND feature of the POSIX API with a
-non-zero starting offset, unset capturing groups with lower numbers than a
-group that did capture something were not being correctly returned as "unset"
-(that is, with offset values of -1).
-
-2. When matching using the POSIX API, pcre2test used to omit listing unset
-groups altogether. Now it shows those that come before any actual captures as
-"<unset>", as happens for non-POSIX matching.
-
-3. Running "pcre2test -C" always stated "\R matches CR, LF, or CRLF only",
-whatever the build configuration was. It now correctly says "\R matches all
-Unicode newlines" in the default case when --enable-bsr-anycrlf has not been
-specified. Similarly, running "pcre2test -C bsr" never produced the result
-ANY.
-
-4. Matching the pattern /(*UTF)\C[^\v]+\x80/ against an 8-bit string containing
-multi-code-unit characters caused bad behaviour and possibly a crash. This
-issue was fixed for other kinds of repeat in release 10.20 by change 19, but
-repeating character classes were overlooked.
-
-5. pcre2grep now supports the inclusion of binary zeros in patterns that are
-read from files via the -f option.
-
-6. A small fix to pcre2grep to avoid compiler warnings for -Wformat-overflow=2.
-
-7. Added --enable-jit=auto support to configure.ac.
-
-8. Added some dummy variables to the heapframe structure in 16-bit and 32-bit
-modes for the benefit of m68k, where pointers can be 16-bit aligned. The
-dummies force 32-bit alignment and this ensures that the structure is a
-multiple of PCRE2_SIZE, a requirement that is tested at compile time. In other
-architectures, alignment requirements take care of this automatically.
-
-9. When returning an error from pcre2_pattern_convert(), ensure the error
-offset is set zero for early errors.
-
-10. A number of patches for Windows support from Daniel Richard G:
-
-  (a) List of error numbers in Runtest.bat corrected (it was not the same as in
-      Runtest).
-
-  (b) pcre2grep snprintf() workaround as used elsewhere in the tree.
-
-  (c) Support for non-C99 snprintf() that returns -1 in the overflow case.
-
-11. Minor tidy of pcre2_dfa_match() code.
-
-12. Refactored pcre2_dfa_match() so that the internal recursive calls no longer
-use the stack for local workspace and local ovectors. Instead, an initial block
-of stack is reserved, but if this is insufficient, heap memory is used. The
-heap limit parameter now applies to pcre2_dfa_match().
-
-13. If a "find limits" test of DFA matching in pcre2test resulted in too many
-matches for the ovector, no matches were displayed.
-
-14. Removed an occurrence of ctrl/Z from test 6 because Windows treats it as
-EOF. The test looks to have come from a fuzzer.
-
-15. If PCRE2 was built with a default match limit a lot greater than the
-default default of 10 000 000, some JIT tests of the match limit no longer
-failed. All such tests now set 10 000 000 as the upper limit.
-
-16. Another Windows related patch for pcregrep to ensure that WIN32 is
-undefined under Cygwin.
-
-17. Test for the presence of stdint.h and inttypes.h in configure and CMake and
-include whichever exists (stdint preferred) instead of unconditionally
-including stdint. This makes life easier for old and non-standard systems.
-
-18. Further changes to improve portability, especially to old and or non-
-standard systems:
-
-  (a) Put all printf arguments in RunGrepTest into single, not double, quotes,
-      and use \0 not \x00 for binary zero.
-
-  (b) Avoid the use of C++ (i.e. BCPL) // comments.
-
-  (c) Parameterize the use of %zu in pcre2test to make it like %td. For both of
-      these now, if using MSVC or a standard C before C99, %lu is used with a
-      cast if necessary.
-
-19. Applied a contributed patch to CMakeLists.txt to increase the stack size
-when linking pcre2test with MSVC. This gets rid of a stack overflow error in
-the standard set of tests.
-
-20. Output a warning in pcre2test when ignoring the "altglobal" modifier when
-it is given with the "replace" modifier.
-
-21. In both pcre2test and pcre2_substitute(), with global matching, a pattern
-that matched an empty string, but never at the starting match offset, was not
-handled in a Perl-compatible way. The pattern /(<?=\G.)/ is an example of such
-a pattern. Because \G is in a lookbehind assertion, there has to be a
-"bumpalong" before there can be a match. The automatic "advance by one
-character after an empty string match" rule is therefore inappropriate. A more
-complicated algorithm has now been implemented.
-
-22. When checking to see if a lookbehind is of fixed length, lookaheads were
-correctly ignored, but qualifiers on lookaheads were not being ignored, leading
-to an incorrect "lookbehind assertion is not fixed length" error.
-
-23. The VERSION condition test was reading fractional PCRE2 version numbers
-such as the 04 in 10.04 incorrectly and hence giving wrong results.
-
-24. Updated to Unicode version 11.0.0. As well as the usual addition of new
-scripts and characters, this involved re-jigging the grapheme break property
-algorithm because Unicode has changed the way emojis are handled.
-
-25. Fixed an obscure bug that struck when there were two atomic groups not
-separated by something with a backtracking point. There could be an incorrect
-backtrack into the first of the atomic groups. A complicated example is
-/(?>a(*:1))(?>b)(*SKIP:1)x|.*/ matched against "abc", where the *SKIP
-shouldn't find a MARK (because is in an atomic group), but it did.
-
-26. Upgraded the perltest.sh script: (1) #pattern lines can now be used to set
-a list of modifiers for all subsequent patterns - only those that the script
-recognizes are meaningful; (2) #subject lines can be used to set or unset a
-default "mark" modifier; (3) Unsupported #command lines give a warning when
-they are ignored; (4) Mark data is output only if the "mark" modifier is
-present.
-
-27. (*ACCEPT:ARG), (*FAIL:ARG), and (*COMMIT:ARG) are now supported.
-
-28. A (*MARK) name was not being passed back for positive assertions that were
-terminated by (*ACCEPT).
-
-29. Add support for \N{U+dddd}, but only in Unicode mode.
-
-30. Add support for (?^) for unsetting all imnsx options.
-
-31. The PCRE2_EXTENDED (/x) option only ever discarded space characters whose
-code point was less than 256 and that were recognized by the lookup table
-generated by pcre2_maketables(), which uses isspace() to identify white space.
-Now, when Unicode support is compiled, PCRE2_EXTENDED also discards U+0085,
-U+200E, U+200F, U+2028, and U+2029, which are additional characters defined by
-Unicode as "Pattern White Space". This makes PCRE2 compatible with Perl.
-
-32. In certain circumstances, option settings within patterns were not being
-correctly processed. For example, the pattern /((?i)A)(?m)B/ incorrectly
-matched "ab". (The (?m) setting lost the fact that (?i) should be reset at the
-end of its group during the parse process, but without another setting such as
-(?m) the compile phase got it right.) This bug was introduced by the
-refactoring in release 10.23.
-
-33. PCRE2 uses bcopy() if available when memmove() is not, and it used just to
-define memmove() as function call to bcopy(). This hasn't been tested for a
-long time because in pcre2test the result of memmove() was being used, whereas
-bcopy() doesn't return a result. This feature is now refactored always to call
-an emulation function when there is no memmove(). The emulation makes use of
-bcopy() when available.
-
-34. When serializing a pattern, set the memctl, executable_jit, and tables
-fields (that is, all the fields that contain pointers) to zeros so that the
-result of serializing is always the same. These fields are re-set when the
-pattern is deserialized.
-
-35. In a pattern such as /[^\x{100}-\x{ffff}]*[\x80-\xff]/ which has a repeated
-negative class with no characters less than 0x100 followed by a positive class
-with only characters less than 0x100, the first class was incorrectly being
-auto-possessified, causing incorrect match failures.
-
-36. Removed the character type bit ctype_meta, which dates from PCRE1 and is
-not used in PCRE2.
-
-37. Tidied up unnecessarily complicated macros used in the escapes table.
-
-38. Since 10.21, the new testoutput8-16-4 file has accidentally been omitted
-from distribution tarballs, owing to a typo in Makefile.am which had
-testoutput8-16-3 twice. Now fixed.
-
-39. If the only branch in a conditional subpattern was anchored, the whole
-subpattern was treated as anchored, when it should not have been, since the
-assumed empty second branch cannot be anchored. Demonstrated by test patterns
-such as /(?(1)^())b/ or /(?(?=^))b/.
-
-40. A repeated conditional subpattern that could match an empty string was
-always assumed to be unanchored. Now it it checked just like any other
-repeated conditional subpattern, and can be found to be anchored if the minimum
-quantifier is one or more. I can't see much use for a repeated anchored
-pattern, but the behaviour is now consistent.
-
-41. Minor addition to pcre2_jit_compile.c to avoid static analyzer complaint
-(for an event that could never occur but you had to have external information
-to know that).
-
-42. If before the first match in a file that was being searched by pcre2grep
-there was a line that was sufficiently long to cause the input buffer to be
-expanded, the variable holding the location of the end of the previous match
-was being adjusted incorrectly, and could cause an overflow warning from a code
-sanitizer. However, as the value is used only to print pending "after" lines
-when the next match is reached (and there are no such lines in this case) this
-bug could do no damage.
-
-
-Version 10.31 12-February-2018
-------------------------------
-
-1. Fix typo (missing ]) in VMS code in pcre2test.c.
-
-2. Replace the replicated code for matching extended Unicode grapheme sequences
-(which got a lot more complicated by change 10.30/49) by a single subroutine
-that is called by both pcre2_match() and pcre2_dfa_match().
-
-3. Add idempotent guard to pcre2_internal.h.
-
-4. Add new pcre2_config() options: PCRE2_CONFIG_NEVER_BACKSLASH_C and
-PCRE2_CONFIG_COMPILED_WIDTHS.
-
-5. Cut out \C tests in the JIT regression tests when NEVER_BACKSLASH_C is
-defined (e.g. by --enable-never-backslash-C).
-
-6. Defined public names for all the pcre2_compile() error numbers, and used
-the public names in pcre2_convert.c.
-
-7. Fixed a small memory leak in pcre2test (convert contexts).
-
-8. Added two casts to compile.c and one to match.c to avoid compiler warnings.
-
-9. Added code to pcre2grep when compiled under VMS to set the symbol
-PCRE2GREP_RC to the exit status, because VMS does not distinguish between
-exit(0) and exit(1).
-
-10. Added the -LM (list modifiers) option to pcre2test. Also made -C complain
-about a bad option only if the following argument item does not start with a
-hyphen.
-
-11. pcre2grep was truncating components of file names to 128 characters when
-processing files with the -r option, and also (some very odd code) truncating
-path names to 512 characters. There is now a check on the absolute length of
-full path file names, which may be up to 2047 characters long.
-
-12. When an assertion contained (*ACCEPT) it caused all open capturing groups
-to be closed (as for a non-assertion ACCEPT), which was wrong and could lead to
-misbehaviour for subsequent references to groups that started outside the
-assertion. ACCEPT in an assertion now closes only those groups that were
-started within that assertion. Fixes oss-fuzz issues 3852 and 3891.
-
-13. Multiline matching in pcre2grep was misbehaving if the pattern matched
-within a line, and then matched again at the end of the line and over into
-subsequent lines. Behaviour was different with and without colouring, and
-sometimes context lines were incorrectly printed and/or line endings were lost.
-All these issues should now be fixed.
-
-14. If --line-buffered was specified for pcre2grep when input was from a
-compressed file (.gz or .bz2) a segfault occurred. (Line buffering should be
-ignored for compressed files.)
-
-15. Although pcre2_jit_match checks whether the pattern is compiled
-in a given mode, it was also expected that at least one mode is available.
-This is fixed and pcre2_jit_match returns with PCRE2_ERROR_JIT_BADOPTION
-when the pattern is not optimized by JIT at all.
-
-16. The line number and related variables such as match counts in pcre2grep
-were all int variables, causing overflow when files with more than 2147483647
-lines were processed (assuming 32-bit ints). They have all been changed to
-unsigned long ints.
-
-17. If a backreference with a minimum repeat count of zero was first in a
-pattern, apart from assertions, an incorrect first matching character could be
-recorded. For example, for the pattern /(?=(a))\1?b/, "b" was incorrectly set
-as the first character of a match.
-
-18. Characters in a leading positive assertion are considered for recording a
-first character of a match when the rest of the pattern does not provide one.
-However, a character in a non-assertive group within a leading assertion such
-as in the pattern /(?=(a))\1?b/ caused this process to fail. This was an
-infelicity rather than an outright bug, because it did not affect the result of
-a match, just its speed. (In fact, in this case, the starting 'a' was
-subsequently picked up in the study.)
-
-19. A minor tidy in pcre2_match(): making all PCRE2_ERROR_ returns use "return"
-instead of "RRETURN" saves unwinding the backtracks in these cases (only one
-didn't).
-
-20. Allocate a single callout block on the stack at the start of pcre2_match()
-and set its never-changing fields once only. Do the same for pcre2_dfa_match().
-
-21. Save the extra compile options (set in the compile context) with the
-compiled pattern (they were not previously saved), add PCRE2_INFO_EXTRAOPTIONS
-to retrieve them, and update pcre2test to show them.
-
-22. Added PCRE2_CALLOUT_STARTMATCH and PCRE2_CALLOUT_BACKTRACK bits to a new
-field callout_flags in callout blocks. The bits are set by pcre2_match(), but
-not by JIT or pcre2_dfa_match(). Their settings are shown in pcre2test callouts
-if the callout_extra subject modifier is set. These bits are provided to help
-with tracking how a backtracking match is proceeding.
-
-23. Updated the pcre2demo.c demonstration program, which was missing the extra
-code for -g that handles the case when \K in an assertion causes the match to
-end at the original start point. Also arranged for it to detect when \K causes
-the end of a match to be before its start.
-
-24. Similar to 23 above, strange things (including loops) could happen in
-pcre2grep when \K was used in an assertion when --colour was used or in
-multiline mode. The "end at original start point" bug is fixed, and if the end
-point is found to be before the start point, they are swapped.
-
-25. When PCRE2_FIRSTLINE without PCRE2_NO_START_OPTIMIZE was used in non-JIT
-matching (both pcre2_match() and pcre2_dfa_match()) and the matched string
-started with the first code unit of a newline sequence, matching failed because
-it was not tried at the newline.
-
-26. Code for giving up a non-partial match after failing to find a starting
-code unit anywhere in the subject was missing when searching for one of a
-number of code units (the bitmap case) in both pcre2_match() and
-pcre2_dfa_match(). This was a missing optimization rather than a bug.
-
-27. Tidied up the ACROSSCHAR macro to be like FORWARDCHAR and BACKCHAR, using a
-pointer argument rather than a code unit value. This should not have affected
-the generated code.
-
-28. The JIT compiler has been updated.
-
-29. Avoid pointer overflow for unset captures in pcre2_substring_list_get().
-This could not actually cause a crash because it was always used in a memcpy()
-call with zero length.
-
-30. Some internal structures have a variable-length ovector[] as their last
-element. Their actual memory is obtained dynamically, giving an ovector of
-appropriate length. However, they are defined in the structure as
-ovector[NUMBER], where NUMBER is large so that array bound checkers don't
-grumble. The value of NUMBER was 10000, but a fuzzer exceeded 5000 capturing
-groups, making the ovector larger than this. The number has been increased to
-131072, which allows for the maximum number of captures (65535) plus the
-overall match. This fixes oss-fuzz issue 5415.
-
-31. Auto-possessification at the end of a capturing group was dependent on what
-follows the group (e.g. /(a+)b/ would auto-possessify the a+) but this caused
-incorrect behaviour when the group was called recursively from elsewhere in the
-pattern where something different might follow. This bug is an unforseen
-consequence of change #1 for 10.30 - the implementation of backtracking into
-recursions. Iterators at the ends of capturing groups are no longer considered
-for auto-possessification if the pattern contains any recursions. Fixes
-Bugzilla #2232.
-
-
-Version 10.30 14-August-2017
-----------------------------
-
-1. The main interpreter, pcre2_match(), has been refactored into a new version
-that does not use recursive function calls (and therefore the stack) for
-remembering backtracking positions. This makes --disable-stack-for-recursion a
-NOOP. The new implementation allows backtracking into recursive group calls in
-patterns, making it more compatible with Perl, and also fixes some other
-hard-to-do issues such as #1887 in Bugzilla. The code is also cleaner because
-the old code had a number of fudges to try to reduce stack usage. It seems to
-run no slower than the old code.
-
-A number of bugs in the refactored code were subsequently fixed during testing
-before release, but after the code was made available in the repository. These
-bugs were never in fully released code, but are noted here for the record.
-
-  (a) If a pattern had fewer capturing parentheses than the ovector supplied in
-      the match data block, a memory error (detectable by ASAN) occurred after
-      a match, because the external block was being set from non-existent
-      internal ovector fields. Fixes oss-fuzz issue 781.
-
-  (b) A pattern with very many capturing parentheses (when the internal frame
-      size was greater than the initial frame vector on the stack) caused a
-      crash. A vector on the heap is now set up at the start of matching if the
-      vector on the stack is not big enough to handle at least 10 frames.
-      Fixes oss-fuzz issue 783.
-
-  (c) Handling of (*VERB)s in recursions was wrong in some cases.
-
-  (d) Captures in negative assertions that were used as conditions were not
-      happening if the assertion matched via (*ACCEPT).
-
-  (e) Mark values were not being passed out of recursions.
-
-  (f) Refactor some code in do_callout() to avoid picky compiler warnings about
-      negative indices. Fixes oss-fuzz issue 1454.
-
-  (g) Similarly refactor the way the variable length ovector is addressed for
-      similar reasons. Fixes oss-fuzz issue 1465.
-
-2. Now that pcre2_match() no longer uses recursive function calls (see above),
-the "match limit recursion" value seems misnamed. It still exists, and limits
-the depth of tree that is searched. To avoid future confusion, it has been
-renamed as "depth limit" in all relevant places (--with-depth-limit,
-(*LIMIT_DEPTH), pcre2_set_depth_limit(), etc) but the old names are still
-available for backwards compatibility.
-
-3. Hardened pcre2test so as to reduce the number of bugs reported by fuzzers:
-
-  (a) Check for malloc failures when getting memory for the ovector (POSIX) or
-      the match data block (non-POSIX).
-
-4. In the 32-bit library in non-UTF mode, an attempt to find a Unicode property
-for a character with a code point greater than 0x10ffff (the Unicode maximum)
-caused a crash.
-
-5. If a lookbehind assertion that contained a back reference to a group
-appearing later in the pattern was compiled with the PCRE2_ANCHORED option,
-undefined actions (often a segmentation fault) could occur, depending on what
-other options were set. An example assertion is (?<!\1(abc)) where the
-reference \1 precedes the group (abc). This fixes oss-fuzz issue 865.
-
-6. Added the PCRE2_INFO_FRAMESIZE item to pcre2_pattern_info() and arranged for
-pcre2test to use it to output the frame size when the "framesize" modifier is
-given.
-
-7. Reworked the recursive pattern matching in the JIT compiler to follow the
-interpreter changes.
-
-8. When the zero_terminate modifier was specified on a pcre2test subject line
-for global matching, unpredictable things could happen. For example, in UTF-8
-mode, the pattern //g,zero_terminate read random memory when matched against an
-empty string with zero_terminate. This was a bug in pcre2test, not the library.
-
-9. Moved some Windows-specific code in pcre2grep (introduced in 10.23/13) out
-of the section that is compiled when Unix-style directory scanning is
-available, and into a new section that is always compiled for Windows.
-
-10. In pcre2test, explicitly close the file after an error during serialization
-or deserialization (the "load" or "save" commands).
-
-11. Fix memory leak in pcre2_serialize_decode() when the input is invalid.
-
-12. Fix potential NULL dereference in pcre2_callout_enumerate() if called with
-a NULL pattern pointer when Unicode support is available.
-
-13. When the 32-bit library was being tested by pcre2test, error messages that
-were longer than 64 code units could cause a buffer overflow. This was a bug in
-pcre2test.
-
-14. The alternative matching function, pcre2_dfa_match() misbehaved if it
-encountered a character class with a possessive repeat, for example [a-f]{3}+.
-
-15. The depth (formerly recursion) limit now applies to DFA matching (as
-of 10.23/36); pcre2test has been upgraded so that \=find_limits works with DFA
-matching to find the minimum value for this limit.
-
-16. Since 10.21, if pcre2_match() was called with a null context, default
-memory allocation functions were used instead of whatever was used when the
-pattern was compiled.
-
-17. Changes to the pcre2test "memory" modifier on a subject line. These apply
-only to pcre2_match():
-
-  (a) Warn if null_context is set on both pattern and subject, because the
-      memory details cannot then be shown.
-
-  (b) Remember (up to a certain number of) memory allocations and their
-      lengths, and list only the lengths, so as to be system-independent.
-      (In practice, the new interpreter never has more than 2 blocks allocated
-      simultaneously.)
-
-18. Make pcre2test detect an error return from pcre2_get_error_message(), give
-a message, and abandon the run (this would have detected #13 above).
-
-19. Implemented PCRE2_ENDANCHORED.
-
-20. Applied Jason Hood's patches (slightly modified) to pcre2grep, to implement
-the --output=text (-O) option and the inbuilt callout echo.
-
-21. Extend auto-anchoring etc. to ignore groups with a zero qualifier and
-single-branch conditions with a false condition (e.g. DEFINE) at the start of a
-branch. For example, /(?(DEFINE)...)^A/ and /(...){0}^B/ are now flagged as
-anchored.
-
-22. Added an explicit limit on the amount of heap used by pcre2_match(), set by
-pcre2_set_heap_limit() or (*LIMIT_HEAP=xxx). Upgraded pcre2test to show the
-heap limit along with other pattern information, and to find the minimum when
-the find_limits modifier is set.
-
-23. Write to the last 8 bytes of the pcre2_real_code structure when a compiled
-pattern is set up so as to initialize any padding the compiler might have
-included. This avoids valgrind warnings when a compiled pattern is copied, in
-particular when it is serialized.
-
-24. Remove a redundant line of code left in accidentally a long time ago.
-
-25. Remove a duplication typo in pcre2_tables.c
-
-26. Correct an incorrect cast in pcre2_valid_utf.c
-
-27. Update pcre2test, remove some unused code in pcre2_match(), and upgrade the
-tests to improve coverage.
-
-28. Some fixes/tidies as a result of looking at Coverity Scan output:
-
-    (a) Typo: ">" should be ">=" in opcode check in pcre2_auto_possess.c.
-    (b) Added some casts to avoid "suspicious implicit sign extension".
-    (c) Resource leaks in pcre2test in rare error cases.
-    (d) Avoid warning for never-use case OP_TABLE_LENGTH which is just a fudge
-        for checking at compile time that tables are the right size.
-    (e) Add missing "fall through" comment.
-
-29. Implemented PCRE2_EXTENDED_MORE and related /xx and (?xx) features.
-
-30. Implement (?n: for PCRE2_NO_AUTO_CAPTURE, because Perl now has this.
-
-31. If more than one of "push", "pushcopy", or "pushtablescopy" were set in
-pcre2test, a crash could occur.
-
-32. Make -bigstack in RunTest allocate a 64MiB stack (instead of 16MiB) so
-that all the tests can run with clang's sanitizing options.
-
-33. Implement extra compile options in the compile context and add the first
-one: PCRE2_EXTRA_ALLOW_SURROGATE_ESCAPES.
-
-34. Implement newline type PCRE2_NEWLINE_NUL.
-
-35. A lookbehind assertion that had a zero-length branch caused undefined
-behaviour when processed by pcre2_dfa_match(). This is oss-fuzz issue 1859.
-
-36. The match limit value now also applies to pcre2_dfa_match() as there are
-patterns that can use up a lot of resources without necessarily recursing very
-deeply. (Compare item 10.23/36.) This should fix oss-fuzz #1761.
-
-37. Implement PCRE2_EXTRA_BAD_ESCAPE_IS_LITERAL.
-
-38. Fix returned offsets from regexec() when REG_STARTEND is used with a
-starting offset greater than zero.
-
-39. Implement REG_PEND (GNU extension) for the POSIX wrapper.
-
-40. Implement the subject_literal modifier in pcre2test, and allow jitstack on
-pattern lines.
-
-41. Implement PCRE2_LITERAL and use it to support REG_NOSPEC.
-
-42. Implement PCRE2_EXTRA_MATCH_LINE and PCRE2_EXTRA_MATCH_WORD for the benefit
-of pcre2grep.
-
-43. Re-implement pcre2grep's -F, -w, and -x options using PCRE2_LITERAL,
-PCRE2_EXTRA_MATCH_WORD, and PCRE2_EXTRA_MATCH_LINE. This fixes two bugs:
-
-    (a) The -F option did not work for fixed strings containing \E.
-    (b) The -w option did not work for patterns with multiple branches.
-
-44. Added configuration options for the SELinux compatible execmem allocator in
-JIT.
-
-45. Increased the limit for searching for a "must be present" code unit in
-subjects from 1000 to 2000 for 8-bit searches, since they use memchr() and are
-much faster.
-
-46. Arrange for anchored patterns to record and use "first code unit" data,
-because this can give a fast "no match" without searching for a "required code
-unit". Previously only non-anchored patterns did this.
-
-47. Upgraded the Unicode tables from Unicode 8.0.0 to Unicode 10.0.0.
-
-48. Add the callout_no_where modifier to pcre2test.
-
-49. Update extended grapheme breaking rules to the latest set that are in
-Unicode Standard Annex #29.
-
-50. Added experimental foreign pattern conversion facilities
-(pcre2_pattern_convert() and friends).
-
-51. Change the macro FWRITE, used in pcre2grep, to FWRITE_IGNORE because FWRITE
-is defined in a system header in cygwin. Also modified some of the #ifdefs in
-pcre2grep related to Windows and Cygwin support.
-
-52. Change 3(g) for 10.23 was a bit too zealous. If a hyphen that follows a
-character class is the last character in the class, Perl does not give a
-warning. PCRE2 now also treats this as a literal.
-
-53. Related to 52, though PCRE2 was throwing an error for [[:digit:]-X] it was
-not doing so for [\d-X] (and similar escapes), as is documented.
-
-54. Fixed a MIPS issue in the JIT compiler reported by Joshua Kinard.
-
-55. Fixed a "maybe uninitialized" warning for class_uchardata in \p handling in
-pcre2_compile() which could never actually trigger (code should have been cut
-out when Unicode support is disabled).
-
-
-Version 10.23 14-February-2017
-------------------------------
-
-1. Extended pcre2test with the utf8_input modifier so that it is able to
-generate all possible 16-bit and 32-bit code unit values in non-UTF modes.
-
-2. In any wide-character mode (8-bit UTF or any 16-bit or 32-bit mode), without
-PCRE2_UCP set, a negative character type such as \D in a positive class should
-cause all characters greater than 255 to match, whatever else is in the class.
-There was a bug that caused this not to happen if a Unicode property item was
-added to such a class, for example [\D\P{Nd}] or [\W\pL].
-
-3. There has been a major re-factoring of the pcre2_compile.c file. Most syntax
-checking is now done in the pre-pass that identifies capturing groups. This has
-reduced the amount of duplication and made the code tidier. While doing this,
-some minor bugs and Perl incompatibilities were fixed, including:
-
-  (a) \Q\E in the middle of a quantifier such as A+\Q\E+ is now ignored instead
-      of giving an invalid quantifier error.
-
-  (b) {0} can now be used after a group in a lookbehind assertion; previously
-      this caused an "assertion is not fixed length" error.
-
-  (c) Perl always treats (?(DEFINE) as a "define" group, even if a group with
-      the name "DEFINE" exists. PCRE2 now does likewise.
-
-  (d) A recursion condition test such as (?(R2)...) must now refer to an
-      existing subpattern.
-
-  (e) A conditional recursion test such as (?(R)...) misbehaved if there was a
-      group whose name began with "R".
-
-  (f) When testing zero-terminated patterns under valgrind, the terminating
-      zero is now marked "no access". This catches bugs that would otherwise
-      show up only with non-zero-terminated patterns.
-
-  (g) A hyphen appearing immediately after a POSIX character class (for example
-      /[[:ascii:]-z]/) now generates an error. Perl does accept this as a
-      literal, but gives a warning, so it seems best to fail it in PCRE.
-
-  (h) An empty \Q\E sequence may appear after a callout that precedes an
-      assertion condition (it is, of course, ignored).
-
-One effect of the refactoring is that some error numbers and messages have
-changed, and the pattern offset given for compiling errors is not always the
-right-most character that has been read. In particular, for a variable-length
-lookbehind assertion it now points to the start of the assertion. Another
-change is that when a callout appears before a group, the "length of next
-pattern item" that is passed now just gives the length of the opening
-parenthesis item, not the length of the whole group. A length of zero is now
-given only for a callout at the end of the pattern. Automatic callouts are no
-longer inserted before and after explicit callouts in the pattern.
-
-A number of bugs in the refactored code were subsequently fixed during testing
-before release, but after the code was made available in the repository. Many
-of the bugs were discovered by fuzzing testing. Several of them were related to
-the change from assuming a zero-terminated pattern (which previously had
-required non-zero terminated strings to be copied). These bugs were never in
-fully released code, but are noted here for the record.
-
-  (a) An overall recursion such as (?0) inside a lookbehind assertion was not
-      being diagnosed as an error.
-
-  (b) In utf mode, the length of a *MARK (or other verb) name was being checked
-      in characters instead of code units, which could lead to bad code being
-      compiled, leading to unpredictable behaviour.
-
-  (c) In extended /x mode, characters whose code was greater than 255 caused
-      a lookup outside one of the global tables. A similar bug existed for wide
-      characters in *VERB names.
-
-  (d) The amount of memory needed for a compiled pattern was miscalculated if a
-      lookbehind contained more than one toplevel branch and the first branch
-      was of length zero.
-
-  (e) In UTF-8 or UTF-16 modes with PCRE2_EXTENDED (/x) set and a non-zero-
-      terminated pattern, if a # comment ran on to the end of the pattern, one
-      or more code units past the end were being read.
-
-  (f) An unterminated repeat at the end of a non-zero-terminated pattern (e.g.
-      "{2,2") could cause reading beyond the pattern.
-
-  (g) When reading a callout string, if the end delimiter was at the end of the
-      pattern one further code unit was read.
-
-  (h) An unterminated number after \g' could cause reading beyond the pattern.
-
-  (i) An insufficient memory size was being computed for compiling with
-      PCRE2_AUTO_CALLOUT.
-
-  (j) A conditional group with an assertion condition used more memory than was
-      allowed for it during parsing, so too many of them could therefore
-      overrun a buffer.
-
-  (k) If parsing a pattern exactly filled the buffer, the internal test for
-      overrun did not check when the final META_END item was added.
-
-  (l) If a lookbehind contained a subroutine call, and the called group
-      contained an option setting such as (?s), and the PCRE2_ANCHORED option
-      was set, unpredictable behaviour could occur. The underlying bug was
-      incorrect code and insufficient checking while searching for the end of
-      the called subroutine in the parsed pattern.
-
-  (m) Quantifiers following (*VERB)s were not being diagnosed as errors.
-
-  (n) The use of \Q...\E in a (*VERB) name when PCRE2_ALT_VERBNAMES and
-      PCRE2_AUTO_CALLOUT were both specified caused undetermined behaviour.
-
-  (o) If \Q was preceded by a quantified item, and the following \E was
-      followed by '?' or '+', and there was at least one literal character
-      between them, an internal error "unexpected repeat" occurred (example:
-      /.+\QX\E+/).
-
-  (p) A buffer overflow could occur while sorting the names in the group name
-      list (depending on the order in which the names were seen).
-
-  (q) A conditional group that started with a callout was not doing the right
-      check for a following assertion, leading to compiling bad code. Example:
-      /(?(C'XX))?!XX/
-
-  (r) If a character whose code point was greater than 0xffff appeared within
-      a lookbehind that was within another lookbehind, the calculation of the
-      lookbehind length went wrong and could provoke an internal error.
-
-  (t) The sequence \E- or \Q\E- after a POSIX class in a character class caused
-      an internal error. Now the hyphen is treated as a literal.
-
-4. Back references are now permitted in lookbehind assertions when there are
-no duplicated group numbers (that is, (?| has not been used), and, if the
-reference is by name, there is only one group of that name. The referenced
-group must, of course be of fixed length.
-
-5. pcre2test has been upgraded so that, when run under valgrind with valgrind
-support enabled, reading past the end of the pattern is detected, both when
-compiling and during callout processing.
-
-6. \g{+<number>} (e.g. \g{+2} ) is now supported. It is a "forward back
-reference" and can be useful in repetitions (compare \g{-<number>} ). Perl does
-not recognize this syntax.
-
-7. Automatic callouts are no longer generated before and after callouts in the
-pattern.
-
-8. When pcre2test was outputing information from a callout, the caret indicator
-for the current position in the subject line was incorrect if it was after an
-escape sequence for a character whose code point was greater than \x{ff}.
-
-9. Change 19 for 10.22 had a typo (PCRE_STATIC_RUNTIME should be
-PCRE2_STATIC_RUNTIME). Fix from David Gaussmann.
-
-10. Added --max-buffer-size to pcre2grep, to allow for automatic buffer
-expansion when long lines are encountered. Original patch by Dmitry
-Cherniachenko.
-
-11. If pcre2grep was compiled with JIT support, but the library was compiled
-without it (something that neither ./configure nor CMake allow, but it can be
-done by editing config.h), pcre2grep was giving a JIT error. Now it detects
-this situation and does not try to use JIT.
-
-12. Added some "const" qualifiers to variables in pcre2grep.
-
-13. Added Dmitry Cherniachenko's patch for colouring output in Windows
-(untested by me). Also, look for GREP_COLOUR or GREP_COLOR if the environment
-variables PCRE2GREP_COLOUR and PCRE2GREP_COLOR are not found.
-
-14. Add the -t (grand total) option to pcre2grep.
-
-15. A number of bugs have been mended relating to match start-up optimizations
-when the first thing in a pattern is a positive lookahead. These all applied
-only when PCRE2_NO_START_OPTIMIZE was *not* set:
-
-    (a) A pattern such as (?=.*X)X$ was incorrectly optimized as if it needed
-        both an initial 'X' and a following 'X'.
-    (b) Some patterns starting with an assertion that started with .* were
-        incorrectly optimized as having to match at the start of the subject or
-        after a newline. There are cases where this is not true, for example,
-        (?=.*[A-Z])(?=.{8,16})(?!.*[\s]) matches after the start in lines that
-        start with spaces. Starting .* in an assertion is no longer taken as an
-        indication of matching at the start (or after a newline).
-
-16. The "offset" modifier in pcre2test was not being ignored (as documented)
-when the POSIX API was in use.
-
-17. Added --enable-fuzz-support to "configure", causing an non-installed
-library containing a test function that can be called by fuzzers to be
-compiled. A non-installed  binary to run the test function locally, called
-pcre2fuzzcheck is also compiled.
-
-18. A pattern with PCRE2_DOTALL (/s) set but not PCRE2_NO_DOTSTAR_ANCHOR, and
-which started with .* inside a positive lookahead was incorrectly being
-compiled as implicitly anchored.
-
-19. Removed all instances of "register" declarations, as they are considered
-obsolete these days and in any case had become very haphazard.
-
-20. Add strerror() to pcre2test for failed file opening.
-
-21. Make pcre2test -C list valgrind support when it is enabled.
-
-22. Add the use_length modifier to pcre2test.
-
-23. Fix an off-by-one bug in pcre2test for the list of names for 'get' and
-'copy' modifiers.
-
-24. Add PCRE2_CALL_CONVENTION into the prototype declarations in pcre2.h as it
-is apparently needed there as well as in the function definitions. (Why did
-nobody ask for this in PCRE1?)
-
-25. Change the _PCRE2_H and _PCRE2_UCP_H guard macros in the header files to
-PCRE2_H_IDEMPOTENT_GUARD and PCRE2_UCP_H_IDEMPOTENT_GUARD to be more standard
-compliant and unique.
-
-26. pcre2-config --libs-posix was listing -lpcre2posix instead of
--lpcre2-posix. Also, the CMake build process was building the library with the
-wrong name.
-
-27. In pcre2test, give some offset information for errors in hex patterns.
-This uses the C99 formatting sequence %td, except for MSVC which doesn't
-support it - %lu is used instead.
-
-28. Implemented pcre2_code_copy_with_tables(), and added pushtablescopy to
-pcre2test for testing it.
-
-29. Fix small memory leak in pcre2test.
-
-30. Fix out-of-bounds read for partial matching of /./ against an empty string
-when the newline type is CRLF.
-
-31. Fix a bug in pcre2test that caused a crash when a locale was set either in
-the current pattern or a previous one and a wide character was matched.
-
-32. The appearance of \p, \P, or \X in a substitution string when
-PCRE2_SUBSTITUTE_EXTENDED was set caused a segmentation fault (NULL
-dereference).
-
-33. If the starting offset was specified as greater than the subject length in
-a call to pcre2_substitute() an out-of-bounds memory reference could occur.
-
-34. When PCRE2 was compiled to use the heap instead of the stack for recursive
-calls to match(), a repeated minimizing caseless back reference, or a
-maximizing one where the two cases had different numbers of code units,
-followed by a caseful back reference, could lose the caselessness of the first
-repeated back reference (example: /(Z)(a)\2{1,2}?(?-i)\1X/i should match ZaAAZX
-but didn't).
-
-35. When a pattern is too complicated, PCRE2 gives up trying to find a minimum
-matching length and just records zero. Typically this happens when there are
-too many nested or recursive back references. If the limit was reached in
-certain recursive cases it failed to be triggered and an internal error could
-be the result.
-
-36. The pcre2_dfa_match() function now takes note of the recursion limit for
-the internal recursive calls that are used for lookrounds and recursions within
-the pattern.
-
-37. More refactoring has got rid of the internal could_be_empty_branch()
-function (around 400 lines of code, including comments) by keeping track of
-could-be-emptiness as the pattern is compiled instead of scanning compiled
-groups. (This would have been much harder before the refactoring of #3 above.)
-This lifts a restriction on the number of branches in a group (more than about
-1100 would give "pattern is too complicated").
-
-38. Add the "-ac" command line option to pcre2test as a synonym for "-pattern
-auto_callout".
-
-39. In a library with Unicode support, incorrect data was compiled for a
-pattern with PCRE2_UCP set without PCRE2_UTF if a class required all wide
-characters to match (for example, /[\s[:^ascii:]]/).
-
-40. The callout_error modifier has been added to pcre2test to make it possible
-to return PCRE2_ERROR_CALLOUT from a callout.
-
-41. A minor change to pcre2grep: colour reset is now "<esc>[0m" instead of
-"<esc>[00m".
-
-42. The limit in the auto-possessification code that was intended to catch
-overly-complicated patterns and not spend too much time auto-possessifying was
-being reset too often, resulting in very long compile times for some patterns.
-Now such patterns are no longer completely auto-possessified.
-
-43. Applied Jason Hood's revised patch for RunTest.bat.
-
-44. Added a new Windows script RunGrepTest.bat, courtesy of Jason Hood.
-
-45. Minor cosmetic fix to pcre2test: move a variable that is not used under
-Windows into the "not Windows" code.
-
-46. Applied Jason Hood's patches to upgrade pcre2grep under Windows and tidy
-some of the code:
-
-  * normalised the Windows condition by ensuring WIN32 is defined;
-  * enables the callout feature under Windows;
-  * adds globbing (Microsoft's implementation expands quoted args),
-    using a tweaked opendirectory;
-  * implements the is_*_tty functions for Windows;
-  * --color=always will write the ANSI sequences to file;
-  * add sequences 4 (underline works on Win10) and 5 (blink as bright
-    background, relatively standard on DOS/Win);
-  * remove the (char *) casts for the now-const strings;
-  * remove GREP_COLOUR (grep's command line allowed the 'u', but not
-    the environment), parsing GREP_COLORS instead;
-  * uses the current colour if not set, rather than black;
-  * add print_match for the undefined case;
-  * fixes a typo.
-
-In addition, colour settings containing anything other than digits and
-semicolon are ignored, and the colour controls are no longer output for empty
-strings.
-
-47. Detecting patterns that are too large inside the length-measuring loop
-saves processing ridiculously long patterns to their end.
-
-48. Ignore PCRE2_CASELESS when processing \h, \H, \v, and \V in classes as it
-just wastes time. In the UTF case it can also produce redundant entries in
-XCLASS lists caused by characters with multiple other cases and pairs of
-characters in the same "not-x" sublists.
-
-49. A pattern such as /(?=(a\K))/ can report the end of the match being before
-its start; pcre2test was not handling this correctly when using the POSIX
-interface (it was OK with the native interface).
-
-50. In pcre2grep, ignore all JIT compile errors. This means that pcre2grep will
-continue to work, falling back to interpretation if anything goes wrong with
-JIT.
-
-51. Applied patches from Christian Persch to configure.ac to make use of the
-AC_USE_SYSTEM_EXTENSIONS macro and to test for functions used by the JIT
-modules.
-
-52. Minor fixes to pcre2grep from Jason Hood:
-    * fixed some spacing;
-    * Windows doesn't usually use single quotes, so I've added a define
-      to use appropriate quotes [in an example];
-    * LC_ALL was displayed as "LCC_ALL";
-    * numbers 11, 12 & 13 should end in "th";
-    * use double quotes in usage message.
-
-53. When autopossessifying, skip empty branches without recursion, to reduce
-stack usage for the benefit of clang with -fsanitize-address, which uses huge
-stack frames. Example pattern: /X?(R||){3335}/. Fixes oss-fuzz issue 553.
-
-54. A pattern with very many explicit back references to a group that is a long
-way from the start of the pattern could take a long time to compile because
-searching for the referenced group in order to find the minimum length was
-being done repeatedly. Now up to 128 group minimum lengths are cached and the
-attempt to find a minimum length is abandoned if there is a back reference to a
-group whose number is greater than 128. (In that case, the pattern is so
-complicated that this optimization probably isn't worth it.) This fixes
-oss-fuzz issue 557.
-
-55. Issue 32 for 10.22 below was not correctly fixed. If pcre2grep in multiline
-mode with --only-matching matched several lines, it restarted scanning at the
-next line instead of moving on to the end of the matched string, which can be
-several lines after the start.
-
-56. Applied Jason Hood's new patch for RunGrepTest.bat that updates it in line
-with updates to the non-Windows version.
-
-
-
-Version 10.22 29-July-2016
---------------------------
-
-1. Applied Jason Hood's patches to RunTest.bat and testdata/wintestoutput3
-to fix problems with running the tests under Windows.
-
-2. Implemented a facility for quoting literal characters within hexadecimal
-patterns in pcre2test, to make it easier to create patterns with just a few
-non-printing characters.
-
-3. Binary zeros are not supported in pcre2test input files. It now detects them
-and gives an error.
-
-4. Updated the valgrind parameters in RunTest: (a) changed smc-check=all to
-smc-check=all-non-file; (b) changed obj:* in the suppression file to obj:??? so
-that it matches only unknown objects.
-
-5. Updated the maintenance script maint/ManyConfigTests to make it easier to
-select individual groups of tests.
-
-6. When the POSIX wrapper function regcomp() is called, the REG_NOSUB option
-used to set PCRE2_NO_AUTO_CAPTURE when calling pcre2_compile(). However, this
-disables the use of back references (and subroutine calls), which are supported
-by other implementations of regcomp() with RE_NOSUB. Therefore, REG_NOSUB no
-longer causes PCRE2_NO_AUTO_CAPTURE to be set, though it still ignores nmatch
-and pmatch when regexec() is called.
-
-7. Because of 6 above, pcre2test has been modified with a new modifier called
-posix_nosub, to call regcomp() with REG_NOSUB. Previously the no_auto_capture
-modifier had this effect. That option is now ignored when the POSIX API is in
-use.
-
-8. Minor tidies to the pcre2demo.c sample program, including more comments
-about its 8-bit-ness.
-
-9. Detect unmatched closing parentheses and give the error in the pre-scan
-instead of later. Previously the pre-scan carried on and could give a
-misleading incorrect error message. For example, /(?J)(?'a'))(?'a')/ gave a
-message about invalid duplicate group names.
-
-10. It has happened that pcre2test was accidentally linked with another POSIX
-regex library instead of libpcre2-posix. In this situation, a call to regcomp()
-(in the other library) may succeed, returning zero, but of course putting its
-own data into the regex_t block. In one example the re_pcre2_code field was
-left as NULL, which made pcre2test think it had not got a compiled POSIX regex,
-so it treated the next line as another pattern line, resulting in a confusing
-error message. A check has been added to pcre2test to see if the data returned
-from a successful call of regcomp() are valid for PCRE2's regcomp(). If they
-are not, an error message is output and the pcre2test run is abandoned. The
-message points out the possibility of a mis-linking. Hopefully this will avoid
-some head-scratching the next time this happens.
-
-11. A pattern such as /(?<=((?C)0))/, which has a callout inside a lookbehind
-assertion, caused pcre2test to output a very large number of spaces when the
-callout was taken, making the program appearing to loop.
-
-12. A pattern that included (*ACCEPT) in the middle of a sufficiently deeply
-nested set of parentheses of sufficient size caused an overflow of the
-compiling workspace (which was diagnosed, but of course is not desirable).
-
-13. Detect missing closing parentheses during the pre-pass for group
-identification.
-
-14. Changed some integer variable types and put in a number of casts, following
-a report of compiler warnings from Visual Studio 2013 and a few tests with
-gcc's -Wconversion (which still throws up a lot).
-
-15. Implemented pcre2_code_copy(), and added pushcopy and #popcopy to pcre2test
-for testing it.
-
-16. Change 66 for 10.21 introduced the use of snprintf() in PCRE2's version of
-regerror(). When the error buffer is too small, my version of snprintf() puts a
-binary zero in the final byte. Bug #1801 seems to show that other versions do
-not do this, leading to bad output from pcre2test when it was checking for
-buffer overflow. It no longer assumes a binary zero at the end of a too-small
-regerror() buffer.
-
-17. Fixed typo ("&&" for "&") in pcre2_study(). Fortunately, this could not
-actually affect anything, by sheer luck.
-
-18. Two minor fixes for MSVC compilation: (a) removal of apparently incorrect
-"const" qualifiers in pcre2test and (b) defining snprintf as _snprintf for
-older MSVC compilers. This has been done both in src/pcre2_internal.h for most
-of the library, and also in src/pcre2posix.c, which no longer includes
-pcre2_internal.h (see 24 below).
-
-19. Applied Chris Wilson's patch (Bugzilla #1681) to CMakeLists.txt for MSVC
-static compilation. Subsequently applied Chris Wilson's second patch, putting
-the first patch under a new option instead of being unconditional when
-PCRE_STATIC is set.
-
-20. Updated pcre2grep to set stdout as binary when run under Windows, so as not
-to convert \r\n at the ends of reflected lines into \r\r\n. This required
-ensuring that other output that is written to stdout (e.g. file names) uses the
-appropriate line terminator: \r\n for Windows, \n otherwise.
-
-21. When a line is too long for pcre2grep's internal buffer, show the maximum
-length in the error message.
-
-22. Added support for string callouts to pcre2grep (Zoltan's patch with PH
-additions).
-
-23. RunTest.bat was missing a "set type" line for test 22.
-
-24. The pcre2posix.c file was including pcre2_internal.h, and using some
-"private" knowledge of the data structures. This is unnecessary; the code has
-been re-factored and no longer includes pcre2_internal.h.
-
-25. A racing condition is fixed in JIT reported by Mozilla.
-
-26. Minor code refactor to avoid "array subscript is below array bounds"
-compiler warning.
-
-27. Minor code refactor to avoid "left shift of negative number" warning.
-
-28. Add a bit more sanity checking to pcre2_serialize_decode() and document
-that it expects trusted data.
-
-29. Fix typo in pcre2_jit_test.c
-
-30. Due to an oversight, pcre2grep was not making use of JIT when available.
-This is now fixed.
-
-31. The RunGrepTest script is updated to use the valgrind suppressions file
-when testing with JIT under valgrind (compare 10.21/51 below). The suppressions
-file is updated so that is now the same as for PCRE1: it suppresses the
-Memcheck warnings Addr16 and Cond in unknown objects (that is, JIT-compiled
-code). Also changed smc-check=all to smc-check=all-non-file as was done for
-RunTest (see 4 above).
-
-32. Implemented the PCRE2_NO_JIT option for pcre2_match().
-
-33. Fix typo that gave a compiler error when JIT not supported.
-
-34. Fix comment describing the returns from find_fixedlength().
-
-35. Fix potential negative index in pcre2test.
-
-36. Calls to pcre2_get_error_message() with error numbers that are never
-returned by PCRE2 functions were returning empty strings. Now the error code
-PCRE2_ERROR_BADDATA is returned. A facility has been added to pcre2test to
-show the texts for given error numbers (i.e. to call pcre2_get_error_message()
-and display what it returns) and a few representative error codes are now
-checked in RunTest.
-
-37. Added "&& !defined(__INTEL_COMPILER)" to the test for __GNUC__ in
-pcre2_match.c, in anticipation that this is needed for the same reason it was
-recently added to pcrecpp.cc in PCRE1.
-
-38. Using -o with -M in pcre2grep could cause unnecessary repeated output when
-the match extended over a line boundary, as it tried to find more matches "on
-the same line" - but it was already over the end.
-
-39. Allow \C in lookbehinds and DFA matching in UTF-32 mode (by converting it
-to the same code as '.' when PCRE2_DOTALL is set).
-
-40. Fix two clang compiler warnings in pcre2test when only one code unit width
-is supported.
-
-41. Upgrade RunTest to automatically re-run test 2 with a large (64MiB) stack
-if it fails when running the interpreter with a 16MiB stack (and if changing
-the stack size via pcre2test is possible). This avoids having to manually set a
-large stack size when testing with clang.
-
-42. Fix register overwite in JIT when SSE2 acceleration is enabled.
-
-43. Detect integer overflow in pcre2test pattern and data repetition counts.
-
-44. In pcre2test, ignore "allcaptures" after DFA matching.
-
-45. Fix unaligned accesses on x86. Patch by Marc Mutz.
-
-46. Fix some more clang compiler warnings.
-
-
-Version 10.21 12-January-2016
------------------------------
-
-1. Improve matching speed of patterns starting with + or * in JIT.
-
-2. Use memchr() to find the first character in an unanchored match in 8-bit
-mode in the interpreter. This gives a significant speed improvement.
-
-3. Removed a redundant copy of the opcode_possessify table in the
-pcre2_auto_possessify.c source.
-
-4. Fix typos in dftables.c for z/OS.
-
-5. Change 36 for 10.20 broke the handling of [[:>:]] and [[:<:]] in that
-processing them could involve a buffer overflow if the following character was
-an opening parenthesis.
-
-6. Change 36 for 10.20 also introduced a bug in processing this pattern:
-/((?x)(*:0))#(?'/. Specifically: if a setting of (?x) was followed by a (*MARK)
-setting (which (*:0) is), then (?x) did not get unset at the end of its group
-during the scan for named groups, and hence the external # was incorrectly
-treated as a comment and the invalid (?' at the end of the pattern was not
-diagnosed. This caused a buffer overflow during the real compile. This bug was
-discovered by Karl Skomski with the LLVM fuzzer.
-
-7. Moved the pcre2_find_bracket() function from src/pcre2_compile.c into its
-own source module to avoid a circular dependency between src/pcre2_compile.c
-and src/pcre2_study.c
-
-8. A callout with a string argument containing an opening square bracket, for
-example /(?C$[$)(?<]/, was incorrectly processed and could provoke a buffer
-overflow. This bug was discovered by Karl Skomski with the LLVM fuzzer.
-
-9. The handling of callouts during the pre-pass for named group identification
-has been tightened up.
-
-10. The quantifier {1} can be ignored, whether greedy, non-greedy, or
-possessive. This is a very minor optimization.
-
-11. A possessively repeated conditional group that could match an empty string,
-for example, /(?(R))*+/, was incorrectly compiled.
-
-12. The Unicode tables have been updated to Unicode 8.0.0 (thanks to Christian
-Persch).
-
-13. An empty comment (?#) in a pattern was incorrectly processed and could
-provoke a buffer overflow. This bug was discovered by Karl Skomski with the
-LLVM fuzzer.
-
-14. Fix infinite recursion in the JIT compiler when certain patterns such as
-/(?:|a|){100}x/ are analysed.
-
-15. Some patterns with character classes involving [: and \\ were incorrectly
-compiled and could cause reading from uninitialized memory or an incorrect
-error diagnosis. Examples are: /[[:\\](?<[::]/ and /[[:\\](?'abc')[a:]. The
-first of these bugs was discovered by Karl Skomski with the LLVM fuzzer.
-
-16. Pathological patterns containing many nested occurrences of [: caused
-pcre2_compile() to run for a very long time. This bug was found by the LLVM
-fuzzer.
-
-17. A missing closing parenthesis for a callout with a string argument was not
-being diagnosed, possibly leading to a buffer overflow. This bug was found by
-the LLVM fuzzer.
-
-18. A conditional group with only one branch has an implicit empty alternative
-branch and must therefore be treated as potentially matching an empty string.
-
-19. If (?R was followed by - or + incorrect behaviour happened instead of a
-diagnostic. This bug was discovered by Karl Skomski with the LLVM fuzzer.
-
-20. Another bug that was introduced by change 36 for 10.20: conditional groups
-whose condition was an assertion preceded by an explicit callout with a string
-argument might be incorrectly processed, especially if the string contained \Q.
-This bug was discovered by Karl Skomski with the LLVM fuzzer.
-
-21. Compiling PCRE2 with the sanitize options of clang showed up a number of
-very pedantic coding infelicities and a buffer overflow while checking a UTF-8
-string if the final multi-byte UTF-8 character was truncated.
-
-22. For Perl compatibility in EBCDIC environments, ranges such as a-z in a
-class, where both values are literal letters in the same case, omit the
-non-letter EBCDIC code points within the range.
-
-23. Finding the minimum matching length of complex patterns with back
-references and/or recursions can take a long time. There is now a cut-off that
-gives up trying to find a minimum length when things get too complex.
-
-24. An optimization has been added that speeds up finding the minimum matching
-length for patterns containing repeated capturing groups or recursions.
-
-25. If a pattern contained a back reference to a group whose number was
-duplicated as a result of appearing in a (?|...) group, the computation of the
-minimum matching length gave a wrong result, which could cause incorrect "no
-match" errors. For such patterns, a minimum matching length cannot at present
-be computed.
-
-26. Added a check for integer overflow in conditions (?(<digits>) and
-(?(R<digits>). This omission was discovered by Karl Skomski with the LLVM
-fuzzer.
-
-27. Fixed an issue when \p{Any} inside an xclass did not read the current
-character.
-
-28. If pcre2grep was given the -q option with -c or -l, or when handling a
-binary file, it incorrectly wrote output to stdout.
-
-29. The JIT compiler did not restore the control verb head in case of *THEN
-control verbs. This issue was found by Karl Skomski with a custom LLVM fuzzer.
-
-30. The way recursive references such as (?3) are compiled has been re-written
-because the old way was the cause of many issues. Now, conversion of the group
-number into a pattern offset does not happen until the pattern has been
-completely compiled. This does mean that detection of all infinitely looping
-recursions is postponed till match time. In the past, some easy ones were
-detected at compile time. This re-writing was done in response to yet another
-bug found by the LLVM fuzzer.
-
-31. A test for a back reference to a non-existent group was missing for items
-such as \987. This caused incorrect code to be compiled. This issue was found
-by Karl Skomski with a custom LLVM fuzzer.
-
-32. Error messages for syntax errors following \g and \k were giving inaccurate
-offsets in the pattern.
-
-33. Improve the performance of starting single character repetitions in JIT.
-
-34. (*LIMIT_MATCH=) now gives an error instead of setting the value to 0.
-
-35. Error messages for syntax errors in *LIMIT_MATCH and *LIMIT_RECURSION now
-give the right offset instead of zero.
-
-36. The JIT compiler should not check repeats after a {0,1} repeat byte code.
-This issue was found by Karl Skomski with a custom LLVM fuzzer.
-
-37. The JIT compiler should restore the control chain for empty possessive
-repeats. This issue was found by Karl Skomski with a custom LLVM fuzzer.
-
-38. A bug which was introduced by the single character repetition optimization
-was fixed.
-
-39. Match limit check added to recursion. This issue was found by Karl Skomski
-with a custom LLVM fuzzer.
-
-40. Arrange for the UTF check in pcre2_match() and pcre2_dfa_match() to look
-only at the part of the subject that is relevant when the starting offset is
-non-zero.
-
-41. Improve first character match in JIT with SSE2 on x86.
-
-42. Fix two assertion fails in JIT. These issues were found by Karl Skomski
-with a custom LLVM fuzzer.
-
-43. Correct the setting of CMAKE_C_FLAGS in CMakeLists.txt (patch from Roy Ivy
-III).
-
-44. Fix bug in RunTest.bat for new test 14, and adjust the script for the added
-test (there are now 20 in total).
-
-45. Fixed a corner case of range optimization in JIT.
-
-46. Add the ${*MARK} facility to pcre2_substitute().
-
-47. Modifier lists in pcre2test were splitting at spaces without the required
-commas.
-
-48. Implemented PCRE2_ALT_VERBNAMES.
-
-49. Fixed two issues in JIT. These were found by Karl Skomski with a custom
-LLVM fuzzer.
-
-50. The pcre2test program has been extended by adding the #newline_default
-command. This has made it possible to run the standard tests when PCRE2 is
-compiled with either CR or CRLF as the default newline convention. As part of
-this work, the new command was added to several test files and the testing
-scripts were modified. The pcre2grep tests can now also be run when there is no
-LF in the default newline convention.
-
-51. The RunTest script has been modified so that, when JIT is used and valgrind
-is specified, a valgrind suppressions file is set up to ignore "Invalid read of
-size 16" errors because these are false positives when the hardware supports
-the SSE2 instruction set.
-
-52. It is now possible to have comment lines amid the subject strings in
-pcre2test (and perltest.sh) input.
-
-53. Implemented PCRE2_USE_OFFSET_LIMIT and pcre2_set_offset_limit().
-
-54. Add the null_context modifier to pcre2test so that calling pcre2_compile()
-and the matching functions with NULL contexts can be tested.
-
-55. Implemented PCRE2_SUBSTITUTE_EXTENDED.
-
-56. In a character class such as [\W\p{Any}] where both a negative-type escape
-("not a word character") and a property escape were present, the property
-escape was being ignored.
-
-57. Fixed integer overflow for patterns whose minimum matching length is very,
-very large.
-
-58. Implemented --never-backslash-C.
-
-59. Change 55 above introduced a bug by which certain patterns provoked the
-erroneous error "\ at end of pattern".
-
-60. The special sequences [[:<:]] and [[:>:]] gave rise to incorrect compiling
-errors or other strange effects if compiled in UCP mode. Found with libFuzzer
-and AddressSanitizer.
-
-61. Whitespace at the end of a pcre2test pattern line caused a spurious error
-message if there were only single-character modifiers. It should be ignored.
-
-62. The use of PCRE2_NO_AUTO_CAPTURE could cause incorrect compilation results
-or segmentation errors for some patterns. Found with libFuzzer and
-AddressSanitizer.
-
-63. Very long names in (*MARK) or (*THEN) etc. items could provoke a buffer
-overflow.
-
-64. Improve error message for overly-complicated patterns.
-
-65. Implemented an optional replication feature for patterns in pcre2test, to
-make it easier to test long repetitive patterns. The tests for 63 above are
-converted to use the new feature.
-
-66. In the POSIX wrapper, if regerror() was given too small a buffer, it could
-misbehave.
-
-67. In pcre2_substitute() in UTF mode, the UTF validity check on the
-replacement string was happening before the length setting when the replacement
-string was zero-terminated.
-
-68. In pcre2_substitute() in UTF mode, PCRE2_NO_UTF_CHECK can be set for the
-second and subsequent calls to pcre2_match().
-
-69. There was no check for integer overflow for a replacement group number in
-pcre2_substitute(). An added check for a number greater than the largest group
-number in the pattern means this is not now needed.
-
-70. The PCRE2-specific VERSION condition didn't work correctly if only one
-digit was given after the decimal point, or if more than two digits were given.
-It now works with one or two digits, and gives a compile time error if more are
-given.
-
-71. In pcre2_substitute() there was the possibility of reading one code unit
-beyond the end of the replacement string.
-
-72. The code for checking a subject's UTF-32 validity for a pattern with a
-lookbehind involved an out-of-bounds pointer, which could potentially cause
-trouble in some environments.
-
-73. The maximum lookbehind length was incorrectly calculated for patterns such
-as /(?<=(a)(?-1))x/ which have a recursion within a backreference.
-
-74. Give an error if a lookbehind assertion is longer than 65535 code units.
-
-75. Give an error in pcre2_substitute() if a match ends before it starts (as a
-result of the use of \K).
-
-76. Check the length of subpattern names and the names in (*MARK:xx) etc.
-dynamically to avoid the possibility of integer overflow.
-
-77. Implement pcre2_set_max_pattern_length() so that programs can restrict the
-size of patterns that they are prepared to handle.
-
-78. (*NO_AUTO_POSSESS) was not working.
-
-79. Adding group information caching improves the speed of compiling when
-checking whether a group has a fixed length and/or could match an empty string,
-especially when recursion or subroutine calls are involved. However, this
-cannot be used when (?| is present in the pattern because the same number may
-be used for groups of different sizes. To catch runaway patterns in this
-situation, counts have been introduced to the functions that scan for empty
-branches or compute fixed lengths.
-
-80. Allow for the possibility of the size of the nest_save structure not being
-a factor of the size of the compiling workspace (it currently is).
-
-81. Check for integer overflow in minimum length calculation and cap it at
-65535.
-
-82. Small optimizations in code for finding the minimum matching length.
-
-83. Lock out configuring for EBCDIC with non-8-bit libraries.
-
-84. Test for error code <= 0 in regerror().
-
-85. Check for too many replacements (more than INT_MAX) in pcre2_substitute().
-
-86. Avoid the possibility of computing with an out-of-bounds pointer (though
-not dereferencing it) while handling lookbehind assertions.
-
-87. Failure to get memory for the match data in regcomp() is now given as a
-regcomp() error instead of waiting for regexec() to pick it up.
-
-88. In pcre2_substitute(), ensure that CRLF is not split when it is a valid
-newline sequence.
-
-89. Paranoid check in regcomp() for bad error code from pcre2_compile().
-
-90. Run test 8 (internal offsets and code sizes) for link sizes 3 and 4 as well
-as for link size 2.
-
-91. Document that JIT has a limit on pattern size, and give more information
-about JIT compile failures in pcre2test.
-
-92. Implement PCRE2_INFO_HASBACKSLASHC.
-
-93. Re-arrange valgrind support code in pcre2test to avoid spurious reports
-with JIT (possibly caused by SSE2?).
-
-94. Support offset_limit in JIT.
-
-95. A sequence such as [[:punct:]b] that is, a POSIX character class followed
-by a single ASCII character in a class item, was incorrectly compiled in UCP
-mode. The POSIX class got lost, but only if the single character followed it.
-
-96. [:punct:] in UCP mode was matching some characters in the range 128-255
-that should not have been matched.
-
-97. If [:^ascii:] or [:^xdigit:] are present in a non-negated class, all
-characters with code points greater than 255 are in the class. When a Unicode
-property was also in the class (if PCRE2_UCP is set, escapes such as \w are
-turned into Unicode properties), wide characters were not correctly handled,
-and could fail to match.
-
-98. In pcre2test, make the "startoffset" modifier a synonym of "offset",
-because it sets the "startoffset" parameter for pcre2_match().
-
-99. If PCRE2_AUTO_CALLOUT was set on a pattern that had a (?# comment between
-an item and its qualifier (for example, A(?#comment)?B) pcre2_compile()
-misbehaved. This bug was found by the LLVM fuzzer.
-
-100. The error for an invalid UTF pattern string always gave the code unit
-offset as zero instead of where the invalidity was found.
-
-101. Further to 97 above, negated classes such as [^[:^ascii:]\d] were also not
-working correctly in UCP mode.
-
-102. Similar to 99 above, if an isolated \E was present between an item and its
-qualifier when PCRE2_AUTO_CALLOUT was set, pcre2_compile() misbehaved. This bug
-was found by the LLVM fuzzer.
-
-103. The POSIX wrapper function regexec() crashed if the option REG_STARTEND
-was set when the pmatch argument was NULL. It now returns REG_INVARG.
-
-104. Allow for up to 32-bit numbers in the ordin() function in pcre2grep.
-
-105. An empty \Q\E sequence between an item and its qualifier caused
-pcre2_compile() to misbehave when auto callouts were enabled. This bug
-was found by the LLVM fuzzer.
-
-106. If both PCRE2_ALT_VERBNAMES and PCRE2_EXTENDED were set, and a (*MARK) or
-other verb "name" ended with whitespace immediately before the closing
-parenthesis, pcre2_compile() misbehaved. Example: /(*:abc )/, but only when
-both those options were set.
-
-107. In a number of places pcre2_compile() was not handling NULL characters
-correctly, and pcre2test with the "bincode" modifier was not always correctly
-displaying fields containing NULLS:
-
-   (a) Within /x extended #-comments
-   (b) Within the "name" part of (*MARK) and other *verbs
-   (c) Within the text argument of a callout
-
-108. If a pattern that was compiled with PCRE2_EXTENDED started with white
-space or a #-type comment that was followed by (?-x), which turns off
-PCRE2_EXTENDED, and there was no subsequent (?x) to turn it on again,
-pcre2_compile() assumed that (?-x) applied to the whole pattern and
-consequently mis-compiled it. This bug was found by the LLVM fuzzer. The fix
-for this bug means that a setting of any of the (?imsxJU) options at the start
-of a pattern is no longer transferred to the options that are returned by
-PCRE2_INFO_ALLOPTIONS. In fact, this was an anachronism that should have
-changed when the effects of those options were all moved to compile time.
-
-109. An escaped closing parenthesis in the "name" part of a (*verb) when
-PCRE2_ALT_VERBNAMES was set caused pcre2_compile() to malfunction. This bug
-was found by the LLVM fuzzer.
-
-110. Implemented PCRE2_SUBSTITUTE_UNSET_EMPTY, and updated pcre2test to make it
-possible to test it.
-
-111. "Harden" pcre2test against ridiculously large values in modifiers and
-command line arguments.
-
-112. Implemented PCRE2_SUBSTITUTE_UNKNOWN_UNSET and PCRE2_SUBSTITUTE_OVERFLOW_
-LENGTH.
-
-113. Fix printing of *MARK names that contain binary zeroes in pcre2test.
-
-
-Version 10.20 30-June-2015
---------------------------
-
-1. Callouts with string arguments have been added.
-
-2. Assertion code generator in JIT has been optimized.
-
-3. The invalid pattern (?(?C) has a missing assertion condition at the end. The
-pcre2_compile() function read past the end of the input before diagnosing an
-error. This bug was discovered by the LLVM fuzzer.
-
-4. Implemented pcre2_callout_enumerate().
-
-5. Fix JIT compilation of conditional blocks whose assertion is converted to
-(*FAIL). E.g: /(?(?!))/.
-
-6. The pattern /(?(?!)^)/ caused references to random memory. This bug was
-discovered by the LLVM fuzzer.
-
-7. The assertion (?!) is optimized to (*FAIL). This was not handled correctly
-when this assertion was used as a condition, for example (?(?!)a|b). In
-pcre2_match() it worked by luck; in pcre2_dfa_match() it gave an incorrect
-error about an unsupported item.
-
-8. For some types of pattern, for example /Z*(|d*){216}/, the auto-
-possessification code could take exponential time to complete. A recursion
-depth limit of 1000 has been imposed to limit the resources used by this
-optimization. This infelicity was discovered by the LLVM fuzzer.
-
-9. A pattern such as /(*UTF)[\S\V\H]/, which contains a negated special class
-such as \S in non-UCP mode, explicit wide characters (> 255) can be ignored
-because \S ensures they are all in the class. The code for doing this was
-interacting badly with the code for computing the amount of space needed to
-compile the pattern, leading to a buffer overflow. This bug was discovered by
-the LLVM fuzzer.
-
-10. A pattern such as /((?2)+)((?1))/ which has mutual recursion nested inside
-other kinds of group caused stack overflow at compile time. This bug was
-discovered by the LLVM fuzzer.
-
-11. A pattern such as /(?1)(?#?'){8}(a)/ which had a parenthesized comment
-between a subroutine call and its quantifier was incorrectly compiled, leading
-to buffer overflow or other errors. This bug was discovered by the LLVM fuzzer.
-
-12. The illegal pattern /(?(?<E>.*!.*)?)/ was not being diagnosed as missing an
-assertion after (?(. The code was failing to check the character after (?(?<
-for the ! or = that would indicate a lookbehind assertion. This bug was
-discovered by the LLVM fuzzer.
-
-13. A pattern such as /X((?2)()*+){2}+/ which has a possessive quantifier with
-a fixed maximum following a group that contains a subroutine reference was
-incorrectly compiled and could trigger buffer overflow. This bug was discovered
-by the LLVM fuzzer.
-
-14. Negative relative recursive references such as (?-7) to non-existent
-subpatterns were not being diagnosed and could lead to unpredictable behaviour.
-This bug was discovered by the LLVM fuzzer.
-
-15. The bug fixed in 14 was due to an integer variable that was unsigned when
-it should have been signed. Some other "int" variables, having been checked,
-have either been changed to uint32_t or commented as "must be signed".
-
-16. A mutual recursion within a lookbehind assertion such as (?<=((?2))((?1)))
-caused a stack overflow instead of the diagnosis of a non-fixed length
-lookbehind assertion. This bug was discovered by the LLVM fuzzer.
-
-17. The use of \K in a positive lookbehind assertion in a non-anchored pattern
-(e.g. /(?<=\Ka)/) could make pcre2grep loop.
-
-18. There was a similar problem to 17 in pcre2test for global matches, though
-the code there did catch the loop.
-
-19. If a greedy quantified \X was preceded by \C in UTF mode (e.g. \C\X*),
-and a subsequent item in the pattern caused a non-match, backtracking over the
-repeated \X did not stop, but carried on past the start of the subject, causing
-reference to random memory and/or a segfault. There were also some other cases
-where backtracking after \C could crash. This set of bugs was discovered by the
-LLVM fuzzer.
-
-20. The function for finding the minimum length of a matching string could take
-a very long time if mutual recursion was present many times in a pattern, for
-example, /((?2){73}(?2))((?1))/. A better mutual recursion detection method has
-been implemented. This infelicity was discovered by the LLVM fuzzer.
-
-21. Implemented PCRE2_NEVER_BACKSLASH_C.
-
-22. The feature for string replication in pcre2test could read from freed
-memory if the replication required a buffer to be extended, and it was not
-working properly in 16-bit and 32-bit modes. This issue was discovered by a
-fuzzer: see http://lcamtuf.coredump.cx/afl/.
-
-23. Added the PCRE2_ALT_CIRCUMFLEX option.
-
-24. Adjust the treatment of \8 and \9 to be the same as the current Perl
-behaviour.
-
-25. Static linking against the PCRE2 library using the pkg-config module was
-failing on missing pthread symbols.
-
-26. If a group that contained a recursive back reference also contained a
-forward reference subroutine call followed by a non-forward-reference
-subroutine call, for example /.((?2)(?R)\1)()/, pcre2_compile() failed to
-compile correct code, leading to undefined behaviour or an internally detected
-error. This bug was discovered by the LLVM fuzzer.
-
-27. Quantification of certain items (e.g. atomic back references) could cause
-incorrect code to be compiled when recursive forward references were involved.
-For example, in this pattern: /(?1)()((((((\1++))\x85)+)|))/. This bug was
-discovered by the LLVM fuzzer.
-
-28. A repeated conditional group whose condition was a reference by name caused
-a buffer overflow if there was more than one group with the given name. This
-bug was discovered by the LLVM fuzzer.
-
-29. A recursive back reference by name within a group that had the same name as
-another group caused a buffer overflow. For example: /(?J)(?'d'(?'d'\g{d}))/.
-This bug was discovered by the LLVM fuzzer.
-
-30. A forward reference by name to a group whose number is the same as the
-current group, for example in this pattern: /(?|(\k'Pm')|(?'Pm'))/, caused a
-buffer overflow at compile time. This bug was discovered by the LLVM fuzzer.
-
-31. Fix -fsanitize=undefined warnings for left shifts of 1 by 31 (it treats 1
-as an int; fixed by writing it as 1u).
-
-32. Fix pcre2grep compile when -std=c99 is used with gcc, though it still gives
-a warning for "fileno" unless -std=gnu99 us used.
-
-33. A lookbehind assertion within a set of mutually recursive subpatterns could
-provoke a buffer overflow. This bug was discovered by the LLVM fuzzer.
-
-34. Give an error for an empty subpattern name such as (?'').
-
-35. Make pcre2test give an error if a pattern that follows #forbud_utf contains
-\P, \p, or \X.
-
-36. The way named subpatterns are handled has been refactored. There is now a
-pre-pass over the regex which does nothing other than identify named
-subpatterns and count the total captures. This means that information about
-named patterns is known before the rest of the compile. In particular, it means
-that forward references can be checked as they are encountered. Previously, the
-code for handling forward references was contorted and led to several errors in
-computing the memory requirements for some patterns, leading to buffer
-overflows.
-
-37. There was no check for integer overflow in subroutine calls such as (?123).
-
-38. The table entry for \l in EBCDIC environments was incorrect, leading to its
-being treated as a literal 'l' instead of causing an error.
-
-39. If a non-capturing group containing a conditional group that could match
-an empty string was repeated, it was not identified as matching an empty string
-itself. For example: /^(?:(?(1)x|)+)+$()/.
-
-40. In an EBCDIC environment, pcretest was mishandling the escape sequences
-\a and \e in test subject lines.
-
-41. In an EBCDIC environment, \a in a pattern was converted to the ASCII
-instead of the EBCDIC value.
-
-42. The handling of \c in an EBCDIC environment has been revised so that it is
-now compatible with the specification in Perl's perlebcdic page.
-
-43. Single character repetition in JIT has been improved. 20-30% speedup
-was achieved on certain patterns.
-
-44. The EBCDIC character 0x41 is a non-breaking space, equivalent to 0xa0 in
-ASCII/Unicode. This has now been added to the list of characters that are
-recognized as white space in EBCDIC.
-
-45. When PCRE2 was compiled without Unicode support, the use of \p and \P gave
-an error (correctly) when used outside a class, but did not give an error
-within a class.
-
-46. \h within a class was incorrectly compiled in EBCDIC environments.
-
-47. JIT should return with error when the compiled pattern requires
-more stack space than the maximum.
-
-48. Fixed a memory leak in pcre2grep when a locale is set.
-
-
-Version 10.10 06-March-2015
----------------------------
-
-1. When a pattern is compiled, it remembers the highest back reference so that
-when matching, if the ovector is too small, extra memory can be obtained to
-use instead. A conditional subpattern whose condition is a check on a capture
-having happened, such as, for example in the pattern /^(?:(a)|b)(?(1)A|B)/, is
-another kind of back reference, but it was not setting the highest
-backreference number. This mattered only if pcre2_match() was called with an
-ovector that was too small to hold the capture, and there was no other kind of
-back reference (a situation which is probably quite rare). The effect of the
-bug was that the condition was always treated as FALSE when the capture could
-not be consulted, leading to a incorrect behaviour by pcre2_match(). This bug
-has been fixed.
-
-2. Functions for serialization and deserialization of sets of compiled patterns
-have been added.
-
-3. The value that is returned by PCRE2_INFO_SIZE has been corrected to remove
-excess code units at the end of the data block that may occasionally occur if
-the code for calculating the size over-estimates. This change stops the
-serialization code copying uninitialized data, to which valgrind objects. The
-documentation of PCRE2_INFO_SIZE was incorrect in stating that the size did not
-include the general overhead. This has been corrected.
-
-4. All code units in every slot in the table of group names are now set, again
-in order to avoid accessing uninitialized data when serializing.
-
-5. The (*NO_JIT) feature is implemented.
-
-6. If a bug that caused pcre2_compile() to use more memory than allocated was
-triggered when using valgrind, the code in (3) above passed a stupidly large
-value to valgrind. This caused a crash instead of an "internal error" return.
-
-7. A reference to a duplicated named group (either a back reference or a test
-for being set in a conditional) that occurred in a part of the pattern where
-PCRE2_DUPNAMES was not set caused the amount of memory needed for the pattern
-to be incorrectly calculated, leading to overwriting.
-
-8. A mutually recursive set of back references such as (\2)(\1) caused a
-segfault at compile time (while trying to find the minimum matching length).
-The infinite loop is now broken (with the minimum length unset, that is, zero).
-
-9. If an assertion that was used as a condition was quantified with a minimum
-of zero, matching went wrong. In particular, if the whole group had unlimited
-repetition and could match an empty string, a segfault was likely. The pattern
-(?(?=0)?)+ is an example that caused this. Perl allows assertions to be
-quantified, but not if they are being used as conditions, so the above pattern
-is faulted by Perl. PCRE2 has now been changed so that it also rejects such
-patterns.
-
-10. The error message for an invalid quantifier has been changed from "nothing
-to repeat" to "quantifier does not follow a repeatable item".
-
-11. If a bad UTF string is compiled with NO_UTF_CHECK, it may succeed, but
-scanning the compiled pattern in subsequent auto-possessification can get out
-of step and lead to an unknown opcode. Previously this could have caused an
-infinite loop. Now it generates an "internal error" error. This is a tidyup,
-not a bug fix; passing bad UTF with NO_UTF_CHECK is documented as having an
-undefined outcome.
-
-12. A UTF pattern containing a "not" match of a non-ASCII character and a
-subroutine reference could loop at compile time. Example: /[^\xff]((?1))/.
-
-13. The locale test (RunTest 3) has been upgraded. It now checks that a locale
-that is found in the output of "locale -a" can actually be set by pcre2test
-before it is accepted. Previously, in an environment where a locale was listed
-but would not set (an example does exist), the test would "pass" without
-actually doing anything. Also the fr_CA locale has been added to the list of
-locales that can be used.
-
-14. Fixed a bug in pcre2_substitute(). If a replacement string ended in a
-capturing group number without parentheses, the last character was incorrectly
-literally included at the end of the replacement string.
-
-15. A possessive capturing group such as (a)*+ with a minimum repeat of zero
-failed to allow the zero-repeat case if pcre2_match() was called with an
-ovector too small to capture the group.
-
-16. Improved error message in pcre2test when setting the stack size (-S) fails.
-
-17. Fixed two bugs in CMakeLists.txt: (1) Some lines had got lost in the
-transfer from PCRE1, meaning that CMake configuration failed if "build tests"
-was selected. (2) The file src/pcre2_serialize.c had not been added to the list
-of PCRE2 sources, which caused a failure to build pcre2test.
-
-18. Fixed typo in pcre2_serialize.c (DECL instead of DEFN) that causes problems
-only on Windows.
-
-19. Use binary input when reading back saved serialized patterns in pcre2test.
-
-20. Added RunTest.bat for running the tests under Windows.
-
-21. "make distclean" was not removing config.h, a file that may be created for
-use with CMake.
-
-22. A pattern such as "((?2){0,1999}())?", which has a group containing a
-forward reference repeated a large (but limited) number of times within a
-repeated outer group that has a zero minimum quantifier, caused incorrect code
-to be compiled, leading to the error "internal error: previously-checked
-referenced subpattern not found" when an incorrect memory address was read.
-This bug was reported as "heap overflow", discovered by Kai Lu of Fortinet's
-FortiGuard Labs. (Added 24-March-2015: CVE-2015-2325 was given to this.)
-
-23. A pattern such as "((?+1)(\1))/" containing a forward reference subroutine
-call within a group that also contained a recursive back reference caused
-incorrect code to be compiled. This bug was reported as "heap overflow",
-discovered by Kai Lu of Fortinet's FortiGuard Labs. (Added 24-March-2015:
-CVE-2015-2326 was given to this.)
-
-24. Computing the size of the JIT read-only data in advance has been a source
-of various issues, and new ones are still appear unfortunately. To fix
-existing and future issues, size computation is eliminated from the code,
-and replaced by on-demand memory allocation.
-
-25. A pattern such as /(?i)[A-`]/, where characters in the other case are
-adjacent to the end of the range, and the range contained characters with more
-than one other case, caused incorrect behaviour when compiled in UTF mode. In
-that example, the range a-j was left out of the class.
-
-
-Version 10.00 05-January-2015
------------------------------
-
-Version 10.00 is the first release of PCRE2, a revised API for the PCRE
-library. Changes prior to 10.00 are logged in the ChangeLog file for the old
-API, up to item 20 for release 8.36.
-
-The code of the library was heavily revised as part of the new API
-implementation. Details of each and every modification were not individually
-logged. In addition to the API changes, the following changes were made. They
-are either new functionality, or bug fixes and other noticeable changes of
-behaviour that were implemented after the code had been forked.
-
-1. Including Unicode support at build time is now enabled by default, but it
-can optionally be disabled. It is not enabled by default at run time (no
-change).
-
-2. The test program, now called pcre2test, was re-specified and almost
-completely re-written. Its input is not compatible with input for pcretest.
-
-3. Patterns may start with (*NOTEMPTY) or (*NOTEMPTY_ATSTART) to set the
-PCRE2_NOTEMPTY or PCRE2_NOTEMPTY_ATSTART options for every subject line that is
-matched by that pattern.
-
-4. For the benefit of those who use PCRE2 via some other application, that is,
-not writing the function calls themselves, it is possible to check the PCRE2
-version by matching a pattern such as /(?(VERSION>=10)yes|no)/ against a
-string such as "yesno".
-
-5. There are case-equivalent Unicode characters whose encodings use different
-numbers of code units in UTF-8. U+023A and U+2C65 are one example. (It is
-theoretically possible for this to happen in UTF-16 too.) If a backreference to
-a group containing one of these characters was greedily repeated, and during
-the match a backtrack occurred, the subject might be backtracked by the wrong
-number of code units. For example, if /^(\x{23a})\1*(.)/ is matched caselessly
-(and in UTF-8 mode) against "\x{23a}\x{2c65}\x{2c65}\x{2c65}", group 2 should
-capture the final character, which is the three bytes E2, B1, and A5 in UTF-8.
-Incorrect backtracking meant that group 2 captured only the last two bytes.
-This bug has been fixed; the new code is slower, but it is used only when the
-strings matched by the repetition are not all the same length.
-
-6. A pattern such as /()a/ was not setting the "first character must be 'a'"
-information. This applied to any pattern with a group that matched no
-characters, for example: /(?:(?=.)|(?<!x))a/.
-
-7. When an (*ACCEPT) is triggered inside capturing parentheses, it arranges for
-those parentheses to be closed with whatever has been captured so far. However,
-it was failing to mark any other groups between the highest capture so far and
-the currrent group as "unset". Thus, the ovector for those groups contained
-whatever was previously there. An example is the pattern /(x)|((*ACCEPT))/ when
-matched against "abcd".
-
-8. The pcre2_substitute() function has been implemented.
-
-9. If an assertion used as a condition was quantified with a minimum of zero
-(an odd thing to do, but it happened), SIGSEGV or other misbehaviour could
-occur.
-
-10. The PCRE2_NO_DOTSTAR_ANCHOR option has been implemented.

-Technical Notes about PCRE2
----------------------------
-
-These are very rough technical notes that record potentially useful information
-about PCRE2 internals. PCRE2 is a library based on the original PCRE library,
-but with a revised (and incompatible) API. To avoid confusion, the original
-library is referred to as PCRE1 below. For information about testing PCRE2, see
-the pcre2test documentation and the comment at the head of the RunTest file.
-
-PCRE1 releases were up to 8.3x when PCRE2 was developed, and later bug fix
-releases remain in the 8.xx series. PCRE2 releases started at 10.00 to avoid
-confusion with PCRE1.
-
-
-Historical note 1
------------------
-
-Many years ago I implemented some regular expression functions to an algorithm
-suggested by Martin Richards. The rather simple patterns were not Unix-like in
-form, and were quite restricted in what they could do by comparison with Perl.
-The interesting part about the algorithm was that the amount of space required
-to hold the compiled form of an expression was known in advance. The code to
-apply an expression did not operate by backtracking, as the original Henry
-Spencer code and current PCRE2 and Perl code does, but instead checked all
-possibilities simultaneously by keeping a list of current states and checking
-all of them as it advanced through the subject string. In the terminology of
-Jeffrey Friedl's book, it was a "DFA algorithm", though it was not a
-traditional Finite State Machine (FSM). When the pattern was all used up, all
-remaining states were possible matches, and the one matching the longest subset
-of the subject string was chosen. This did not necessarily maximize the
-individual wild portions of the pattern, as is expected in Unix and Perl-style
-regular expressions.
-
-
-Historical note 2
------------------
-
-By contrast, the code originally written by Henry Spencer (which was
-subsequently heavily modified for Perl) compiles the expression twice: once in
-a dummy mode in order to find out how much store will be needed, and then for
-real. (The Perl version probably doesn't do this any more; I'm talking about
-the original library.) The execution function operates by backtracking and
-maximizing (or, optionally, minimizing, in Perl) the amount of the subject that
-matches individual wild portions of the pattern. This is an "NFA algorithm" in
-Friedl's terminology.
-
-
-OK, here's the real stuff
--------------------------
-
-For the set of functions that formed the original PCRE1 library in 1997 (which
-are unrelated to those mentioned above), I tried at first to invent an
-algorithm that used an amount of store bounded by a multiple of the number of
-characters in the pattern, to save on compiling time. However, because of the
-greater complexity in Perl regular expressions, I couldn't do this, even though
-the then current Perl 5.004 patterns were much simpler than those supported
-nowadays. In any case, a first pass through the pattern is helpful for other
-reasons.
-
-
-Support for 16-bit and 32-bit data strings
--------------------------------------------
-
-The PCRE2 library can be compiled in any combination of 8-bit, 16-bit or 32-bit
-modes, creating up to three different libraries. In the description that
-follows, the word "short" is used for a 16-bit data quantity, and the phrase
-"code unit" is used for a quantity that is a byte in 8-bit mode, a short in
-16-bit mode and a 32-bit word in 32-bit mode. The names of PCRE2 functions are
-given in generic form, without the _8, _16, or _32 suffix.
-
-
-Computing the memory requirement: how it was
---------------------------------------------
-
-Up to and including release 6.7, PCRE1 worked by running a very degenerate
-first pass to calculate a maximum memory requirement, and then a second pass to
-do the real compile - which might use a bit less than the predicted amount of
-memory. The idea was that this would turn out faster than the Henry Spencer
-code because the first pass is degenerate and the second pass can just store
-stuff straight into memory, which it knows is big enough.
-
-
-Computing the memory requirement: how it is
--------------------------------------------
-
-By the time I was working on a potential 6.8 release, the degenerate first pass
-had become very complicated and hard to maintain. Indeed one of the early
-things I did for 6.8 was to fix Yet Another Bug in the memory computation. Then
-I had a flash of inspiration as to how I could run the real compile function in
-a "fake" mode that enables it to compute how much memory it would need, while
-in most cases only ever using a small amount of working memory, and without too
-many tests of the mode that might slow it down. So I refactored the compiling
-functions to work this way. This got rid of about 600 lines of source and made
-further maintenance and development easier. As this was such a major change, I
-never released 6.8, instead upping the number to 7.0 (other quite major changes
-were also present in the 7.0 release).
-
-A side effect of this work was that the previous limit of 200 on the nesting
-depth of parentheses was removed. However, there was a downside: compiling ran
-more slowly than before (30% or more, depending on the pattern) because it now
-did a full analysis of the pattern. My hope was that this would not be a big
-issue, and in the event, nobody has commented on it.
-
-At release 8.34, a limit on the nesting depth of parentheses was re-introduced
-(default 250, settable at build time) so as to put a limit on the amount of
-system stack used by the compile function, which uses recursive function calls
-for nested parenthesized groups. This is a safety feature for environments with
-small stacks where the patterns are provided by users.
-
-
-Yet another pattern scan
-------------------------
-
-History repeated itself for PCRE2 release 10.20. A number of bugs relating to
-named subpatterns had been discovered by fuzzers. Most of these were related to
-the handling of forward references when it was not known if the named group was
-unique. (References to non-unique names use a different opcode and more
-memory.) The use of duplicate group numbers (the (?| facility) also caused
-issues.
-
-To get around these problems I adopted a new approach by adding a third pass
-over the pattern (really a "pre-pass"), which did nothing other than identify
-all the named subpatterns and their corresponding group numbers. This means
-that the actual compile (both the memory-computing dummy run and the real
-compile) has full knowledge of group names and numbers throughout. Several
-dozen lines of messy code were eliminated, though the new pre-pass was not
-short. In particular, parsing and skipping over [] classes is complicated.
-
-While working on 10.22 I realized that I could simplify yet again by moving
-more of the parsing into the pre-pass, thus avoiding doing it in two places, so
-after 10.22 was released, the code underwent yet another big refactoring. This
-is how it is from 10.23 onwards:
-
-The function called parse_regex() scans the pattern characters, parsing them
-into literal data and meta characters. It converts escapes such as \x{123}
-into literals, handles \Q...\E, and skips over comments and non-significant
-white space. The result of the scanning is put into a vector of 32-bit unsigned
-integers. Values less than 0x80000000 are literal data. Higher values represent
-meta-characters. The top 16-bits of such values identify the meta-character,
-and these are given names such as META_CAPTURE. The lower 16-bits are available
-for data, for example, the capturing group number. The only situation in which
-literal data values greater than 0x7fffffff can appear is when the 32-bit
-library is running in non-UTF mode. This is handled by having a special
-meta-character that is followed by the 32-bit data value.
-
-The size of the parsed pattern vector, when auto-callouts are not enabled, is
-bounded by the length of the pattern (with one exception). The code is written
-so that each item in the pattern uses no more vector elements than the number
-of code units in the item itself. The exception is the aforementioned large
-32-bit number handling. For this reason, 32-bit non-UTF patterns are scanned in
-advance to check for such values. When auto-callouts are enabled, the generous
-assumption is made that there will be a callout for each pattern code unit
-(which of course is only actually true if all code units are literals) plus one
-at the end. There is a default parsed pattern vector on the system stack, but
-if this is not big enough, heap memory is used.
-
-As before, the actual compiling function is run twice, the first time to
-determine the amount of memory needed for the final compiled pattern. It
-now processes the parsed pattern vector, not the pattern itself, although some
-of the parsed items refer to strings in the pattern - for example, group
-names. As escapes and comments have already been processed, the code is a bit
-simpler than before.
-
-Most errors can be diagnosed during the parsing scan. For those that cannot
-(for example, "lookbehind assertion is not fixed length"), the parsed code
-contains offsets into the pattern so that the actual compiling code can
-report where errors are.
-
-
-The elements of the parsed pattern vector
------------------------------------------
-
-The word "offset" below means a code unit offset into the pattern. When
-PCRE2_SIZE (which is usually size_t) is no bigger than uint32_t, an offset is
-stored in a single parsed pattern element. Otherwise (typically on 64-bit
-systems) it occupies two elements. The following meta items occupy just one
-element, with no data:
-
-META_ACCEPT           (*ACCEPT)
-META_ASTERISK         *
-META_ASTERISK_PLUS    *+
-META_ASTERISK_QUERY   *?
-META_ATOMIC           (?> start of atomic group
-META_CIRCUMFLEX       ^ metacharacter
-META_CLASS            [ start of non-empty class
-META_CLASS_EMPTY      [] empty class - only with PCRE2_ALLOW_EMPTY_CLASS
-META_CLASS_EMPTY_NOT  [^] negative empty class - ditto
-META_CLASS_END        ] end of non-empty class
-META_CLASS_NOT        [^ start non-empty negative class
-META_COMMIT           (*COMMIT)
-META_COND_ASSERT      (?(?assertion)
-META_DOLLAR           $ metacharacter
-META_DOT              . metacharacter
-META_END              End of pattern (this value is 0x80000000)
-META_FAIL             (*FAIL)
-META_KET              ) closing parenthesis
-META_LOOKAHEAD        (?= start of lookahead
-META_LOOKAHEAD_NA     (*napla: start of non-atomic lookahead
-META_LOOKAHEADNOT     (?! start of negative lookahead
-META_NOCAPTURE        (?: no capture parens
-META_PLUS             +
-META_PLUS_PLUS        ++
-META_PLUS_QUERY       +?
-META_PRUNE            (*PRUNE) - no argument
-META_QUERY            ?
-META_QUERY_PLUS       ?+
-META_QUERY_QUERY      ??
-META_RANGE_ESCAPED    hyphen in class range with at least one escape
-META_RANGE_LITERAL    hyphen in class range defined literally
-META_SKIP             (*SKIP) - no argument
-META_THEN             (*THEN) - no argument
-
-The two RANGE values occur only in character classes. They are positioned
-between two literals that define the start and end of the range. In an EBCDIC
-evironment it is necessary to know whether either of the range values was
-specified as an escape. In an ASCII/Unicode environment the distinction is not
-relevant.
-
-The following have data in the lower 16 bits, and may be followed by other data
-elements:
-
-META_ALT              | alternation
-META_BACKREF          back reference
-META_CAPTURE          start of capturing group
-META_ESCAPE           non-literal escape sequence
-META_RECURSE          recursion call
-
-If the data for META_ALT is non-zero, it is inside a lookbehind, and the data
-is the length of its branch, for which OP_REVERSE must be generated.
-
-META_BACKREF, META_CAPTURE, and META_RECURSE have the capture group number as
-their data in the lower 16 bits of the element.
-
-META_BACKREF is followed by an offset if the back reference group number is 10
-or more. The offsets of the first ocurrences of references to groups whose
-numbers are less than 10 are put in cb->small_ref_offset[] (only the first
-occurrence is useful). On 64-bit systems this avoids using more than two parsed
-pattern elements for items such as \3. The offset is used when an error occurs
-because the reference is to a non-existent group.
-
-META_RECURSE is always followed by an offset, for use in error messages.
-
-META_ESCAPE has an ESC_xxx value as its data. For ESC_P and ESC_p, the next
-element contains the 16-bit type and data property values, packed together.
-ESC_g and ESC_k are used only for named references - numerical ones are turned
-into META_RECURSE or META_BACKREF as appropriate. ESC_g and ESC_k are followed
-by a length and an offset into the pattern to specify the name.
-
-The following have one data item that follows in the next vector element:
-
-META_BIGVALUE         Next is a literal >= META_END
-META_OPTIONS          (?i) and friends (data is new option bits)
-META_POSIX            POSIX class item (data identifies the class)
-META_POSIX_NEG        negative POSIX class item (ditto)
-
-The following are followed by a length element, then a number of character code
-values (which should match with the length):
-
-META_MARK             (*MARK:xxxx)
-META_COMMIT_ARG       )*COMMIT:xxxx)
-META_PRUNE_ARG        (*PRUNE:xxx)
-META_SKIP_ARG         (*SKIP:xxxx)
-META_THEN_ARG         (*THEN:xxxx)
-
-The following are followed by a length element, then an offset in the pattern
-that identifies the name:
-
-META_COND_NAME        (?(<name>) or (?('name') or (?(name)
-META_COND_RNAME       (?(R&name)
-META_COND_RNUMBER     (?(Rdigits)
-META_RECURSE_BYNAME   (?&name)
-META_BACKREF_BYNAME   \k'name'
-
-META_COND_RNUMBER is used for names that start with R and continue with digits,
-because this is an ambiguous case. It could be a back reference to a group with
-that name, or it could be a recursion test on a numbered group.
-
-This one is followed by an offset, for use in error messages, then a number:
-
-META_COND_NUMBER       (?([+-]digits)
-
-The following is followed just by an offset, for use in error messages:
-
-META_COND_DEFINE      (?(DEFINE)
-
-The following are also followed just by an offset, but also the lower 16 bits
-of the main word contain the length of the first branch of the lookbehind
-group; this is used when generating OP_REVERSE for that branch.
-
-META_LOOKBEHIND       (?<=      start of lookbehind
-META_LOOKBEHIND_NA    (*naplb:  start of non-atomic lookbehind
-META_LOOKBEHINDNOT    (?<!      start of negative lookbehind
-
-The following are followed by two elements, the minimum and maximum. Repeat
-values are limited to 65535 (MAX_REPEAT). A maximum value of "unlimited" is
-represented by UNLIMITED_REPEAT, which is bigger than MAX_REPEAT:
-
-META_MINMAX           {n,m}  repeat
-META_MINMAX_PLUS      {n,m}+ repeat
-META_MINMAX_QUERY     {n,m}? repeat
-
-This one is followed by three elements. The first is 0 for '>' and 1 for '>=';
-the next two are the major and minor numbers:
-
-META_COND_VERSION     (?(VERSION<op>x.y)
-
-Callouts are converted into one of two items:
-
-META_CALLOUT_NUMBER   (?C with numerical argument
-META_CALLOUT_STRING   (?C with string argument
-
-In both cases, the next two elements contain the offset and length of the next
-item in the pattern. Then there is either one callout number, or a length and
-an offset for the string argument. The length includes both delimiters.
-
-
-Traditional matching function
------------------------------
-
-The "traditional", and original, matching function is called pcre2_match(), and
-it implements an NFA algorithm, similar to the original Henry Spencer algorithm
-and the way that Perl works. This is not surprising, since it is intended to be
-as compatible with Perl as possible. This is the function most users of PCRE2
-will use most of the time. If PCRE2 is compiled with just-in-time (JIT)
-support, and studying a compiled pattern with JIT is successful, the JIT code
-is run instead of the normal pcre2_match() code, but the result is the same.
-
-
-Supplementary matching function
--------------------------------
-
-There is also a supplementary matching function called pcre2_dfa_match(). This
-implements a DFA matching algorithm that searches simultaneously for all
-possible matches that start at one point in the subject string. (Going back to
-my roots: see Historical Note 1 above.) This function intreprets the same
-compiled pattern data as pcre2_match(); however, not all the facilities are
-available, and those that are do not always work in quite the same way. See the
-user documentation for details.
-
-The algorithm that is used for pcre2_dfa_match() is not a traditional FSM,
-because it may have a number of states active at one time. More work would be
-needed at compile time to produce a traditional FSM where only one state is
-ever active at once. I believe some other regex matchers work this way. JIT
-support is not available for this kind of matching.
-
-
-Changeable options
-------------------
-
-The /i, /m, or /s options (PCRE2_CASELESS, PCRE2_MULTILINE, PCRE2_DOTALL, and
-others) may be changed in the middle of patterns by items such as (?i). Their
-processing is handled entirely at compile time by generating different opcodes
-for the different settings. The runtime functions do not need to keep track of
-an option's state.
-
-PCRE2_DUPNAMES, PCRE2_EXTENDED, PCRE2_EXTENDED_MORE, and PCRE2_NO_AUTO_CAPTURE
-are tracked and processed during the parsing pre-pass. The others are handled
-from META_OPTIONS items during the main compile phase.
-
-
-Format of compiled patterns
----------------------------
-
-The compiled form of a pattern is a vector of unsigned code units (bytes in
-8-bit mode, shorts in 16-bit mode, 32-bit words in 32-bit mode), containing
-items of variable length. The first code unit in an item contains an opcode,
-and the length of the item is either implicit in the opcode or contained in the
-data that follows it.
-
-In many cases listed below, LINK_SIZE data values are specified for offsets
-within the compiled pattern. LINK_SIZE always specifies a number of bytes. The
-default value for LINK_SIZE is 2, except for the 32-bit library, where it can
-only be 4. The 8-bit library can be compiled to used 3-byte or 4-byte values,
-and the 16-bit library can be compiled to use 4-byte values, though this
-impairs performance. Specifing a LINK_SIZE larger than 2 for these libraries is
-necessary only when patterns whose compiled length is greater than 65535 code
-units are going to be processed. When a LINK_SIZE value uses more than one code
-unit, the most significant unit is first.
-
-In this description, we assume the "normal" compilation options. Data values
-that are counts (e.g. quantifiers) are always two bytes long in 8-bit mode
-(most significant byte first), and one code unit in 16-bit and 32-bit modes.
-
-
-Opcodes with no following data
-------------------------------
-
-These items are all just one unit long:
-
-  OP_END                 end of pattern
-  OP_ANY                 match any one character other than newline
-  OP_ALLANY              match any one character, including newline
-  OP_ANYBYTE             match any single code unit, even in UTF-8/16 mode
-  OP_SOD                 match start of data: \A
-  OP_SOM,                start of match (subject + offset): \G
-  OP_SET_SOM,            set start of match (\K)
-  OP_CIRC                ^ (start of data)
-  OP_CIRCM               ^ multiline mode (start of data or after newline)
-  OP_NOT_WORD_BOUNDARY   \W
-  OP_WORD_BOUNDARY       \w
-  OP_NOT_DIGIT           \D
-  OP_DIGIT               \d
-  OP_NOT_HSPACE          \H
-  OP_HSPACE              \h
-  OP_NOT_WHITESPACE      \S
-  OP_WHITESPACE          \s
-  OP_NOT_VSPACE          \V
-  OP_VSPACE              \v
-  OP_NOT_WORDCHAR        \W
-  OP_WORDCHAR            \w
-  OP_EODN                match end of data or newline at end: \Z
-  OP_EOD                 match end of data: \z
-  OP_DOLL                $ (end of data, or before final newline)
-  OP_DOLLM               $ multiline mode (end of data or before newline)
-  OP_EXTUNI              match an extended Unicode grapheme cluster
-  OP_ANYNL               match any Unicode newline sequence
-
-  OP_ASSERT_ACCEPT       )
-  OP_ACCEPT              ) These are Perl 5.10's "backtracking control
-  OP_COMMIT              ) verbs". If OP_ACCEPT is inside capturing
-  OP_FAIL                ) parentheses, it may be preceded by one or more
-  OP_PRUNE               ) OP_CLOSE, each followed by a number that
-  OP_SKIP                ) indicates which parentheses must be closed.
-  OP_THEN                )
-
-OP_ASSERT_ACCEPT is used when (*ACCEPT) is encountered within an assertion.
-This ends the assertion, not the entire pattern match. The assertion (?!) is
-always optimized to OP_FAIL.
-
-OP_ALLANY is used for '.' when PCRE2_DOTALL is set. It is also used for \C in
-non-UTF modes and in UTF-32 mode (since one code unit still equals one
-character). Another use is for [^] when empty classes are permitted
-(PCRE2_ALLOW_EMPTY_CLASS is set).
-
-
-Backtracking control verbs
---------------------------
-
-Verbs with no arguments generate opcodes with no following data (as listed
-in the section above). 
-
-(*MARK:NAME) generates OP_MARK followed by the mark name, preceded by a
-length in one code unit, and followed by a binary zero. The name length is
-limited by the size of the code unit.
-
-(*ACCEPT:NAME) and (*FAIL:NAME) are compiled as (*MARK:NAME)(*ACCEPT) and
-(*MARK:NAME)(*FAIL) respectively.
-
-For (*COMMIT:NAME), (*PRUNE:NAME), (*SKIP:NAME), and (*THEN:NAME), the opcodes
-OP_COMMIT_ARG, OP_PRUNE_ARG, OP_SKIP_ARG, and OP_THEN_ARG are used, with the
-name following in the same format as for OP_MARK.
-
-
-Matching literal characters
----------------------------
-
-The OP_CHAR opcode is followed by a single character that is to be matched
-casefully. For caseless matching of characters that have at most two
-case-equivalent code points, OP_CHARI is used. In UTF-8 or UTF-16 modes, the
-character may be more than one code unit long. In UTF-32 mode, characters are
-always exactly one code unit long.
-
-If there is only one character in a character class, OP_CHAR or OP_CHARI is
-used for a positive class, and OP_NOT or OP_NOTI for a negative one (that is,
-for something like [^a]).
-
-Caseless matching (positive or negative) of characters that have more than two
-case-equivalent code points (which is possible only in UTF mode) is handled by
-compiling a Unicode property item (see below), with the pseudo-property
-PT_CLIST. The value of this property is an offset in a vector called
-"ucd_caseless_sets" which identifies the start of a short list of equivalent
-characters, terminated by the value NOTACHAR (0xffffffff).
-
-
-Repeating single characters
----------------------------
-
-The common repeats (*, +, ?), when applied to a single character, use the
-following opcodes, which come in caseful and caseless versions:
-
-  Caseful         Caseless
-  OP_STAR         OP_STARI
-  OP_MINSTAR      OP_MINSTARI
-  OP_POSSTAR      OP_POSSTARI
-  OP_PLUS         OP_PLUSI
-  OP_MINPLUS      OP_MINPLUSI
-  OP_POSPLUS      OP_POSPLUSI
-  OP_QUERY        OP_QUERYI
-  OP_MINQUERY     OP_MINQUERYI
-  OP_POSQUERY     OP_POSQUERYI
-
-Each opcode is followed by the character that is to be repeated. In ASCII or
-UTF-32 modes, these are two-code-unit items; in UTF-8 or UTF-16 modes, the
-length is variable. Those with "MIN" in their names are the minimizing
-versions. Those with "POS" in their names are possessive versions. Other kinds
-of repeat make use of these opcodes:
-
-  Caseful         Caseless
-  OP_UPTO         OP_UPTOI
-  OP_MINUPTO      OP_MINUPTOI
-  OP_POSUPTO      OP_POSUPTOI
-  OP_EXACT        OP_EXACTI
-
-Each of these is followed by a count and then the repeated character. The count
-is two bytes long in 8-bit mode (most significant byte first), or one code unit
-in 16-bit and 32-bit modes.
-
-OP_UPTO matches from 0 to the given number. A repeat with a non-zero minimum
-and a fixed maximum is coded as an OP_EXACT followed by an OP_UPTO (or
-OP_MINUPTO or OPT_POSUPTO).
-
-Another set of matching repeating opcodes (called OP_NOTSTAR, OP_NOTSTARI,
-etc.) are used for repeated, negated, single-character classes such as [^a]*.
-The normal single-character opcodes (OP_STAR, etc.) are used for repeated
-positive single-character classes.
-
-
-Repeating character types
--------------------------
-
-Repeats of things like \d are done exactly as for single characters, except
-that instead of a character, the opcode for the type (e.g. OP_DIGIT) is stored
-in the next code unit. The opcodes are:
-
-  OP_TYPESTAR
-  OP_TYPEMINSTAR
-  OP_TYPEPOSSTAR
-  OP_TYPEPLUS
-  OP_TYPEMINPLUS
-  OP_TYPEPOSPLUS
-  OP_TYPEQUERY
-  OP_TYPEMINQUERY
-  OP_TYPEPOSQUERY
-  OP_TYPEUPTO
-  OP_TYPEMINUPTO
-  OP_TYPEPOSUPTO
-  OP_TYPEEXACT
-
-
-Match by Unicode property
--------------------------
-
-OP_PROP and OP_NOTPROP are used for positive and negative matches of a
-character by testing its Unicode property (the \p and \P escape sequences).
-Each is followed by two code units that encode the desired property as a type
-and a value. The types are a set of #defines of the form PT_xxx, and the values
-are enumerations of the form ucp_xx, defined in the pcre2_ucp.h source file.
-The value is relevant only for PT_GC (General Category), PT_PC (Particular
-Category), PT_SC (Script), and the pseudo-property PT_CLIST, which is used to
-identify a list of case-equivalent characters when there are three or more.
-
-Repeats of these items use the OP_TYPESTAR etc. set of opcodes, followed by
-three code units: OP_PROP or OP_NOTPROP, and then the desired property type and
-value.
-
-
-Character classes
------------------
-
-If there is only one character in a class, OP_CHAR or OP_CHARI is used for a
-positive class, and OP_NOT or OP_NOTI for a negative one (that is, for
-something like [^a]), except when caselessly matching a character that has more
-than two case-equivalent code points (which can happen only in UTF mode). In
-this case a Unicode property item is used, as described above in "Matching
-literal characters".
-
-A set of repeating opcodes (called OP_NOTSTAR etc.) are used for repeated,
-negated, single-character classes. The normal single-character opcodes
-(OP_STAR, etc.) are used for repeated positive single-character classes.
-
-When there is more than one character in a class, and all the code points are
-less than 256, OP_CLASS is used for a positive class, and OP_NCLASS for a
-negative one. In either case, the opcode is followed by a 32-byte (16-short,
-8-word) bit map containing a 1 bit for every character that is acceptable. The
-bits are counted from the least significant end of each unit. In caseless mode,
-bits for both cases are set.
-
-The reason for having both OP_CLASS and OP_NCLASS is so that, in UTF-8 and
-16-bit and 32-bit modes, subject characters with values greater than 255 can be
-handled correctly. For OP_CLASS they do not match, whereas for OP_NCLASS they
-do.
-
-For classes containing characters with values greater than 255 or that contain
-\p or \P, OP_XCLASS is used. It optionally uses a bit map if any acceptable
-code points are less than 256, followed by a list of pairs (for a range) and/or
-single characters and/or properties. In caseless mode, all equivalent
-characters are explicitly listed.
-
-OP_XCLASS is followed by a LINK_SIZE value containing the total length of the
-opcode and its data. This is followed by a code unit containing flag bits:
-XCL_NOT indicates that this is a negative class, and XCL_MAP indicates that a
-bit map is present. There follows the bit map, if XCL_MAP is set, and then a
-sequence of items coded as follows:
-
-  XCL_END      marks the end of the list
-  XCL_SINGLE   one character follows
-  XCL_RANGE    two characters follow
-  XCL_PROP     a Unicode property (type, value) follows
-  XCL_NOTPROP  a Unicode property (type, value) follows
-
-If a range starts with a code point less than 256 and ends with one greater
-than 255, it is split into two ranges, with characters less than 256 being
-indicated in the bit map, and the rest with XCL_RANGE.
-
-When XCL_NOT is set, the bit map, if present, contains bits for characters that
-are allowed (exactly as for OP_NCLASS), but the list of items that follow it
-specifies characters and properties that are not allowed.
-
-
-Back references
----------------
-
-OP_REF (caseful) or OP_REFI (caseless) is followed by a count containing the
-reference number when the reference is to a unique capturing group (either by
-number or by name). When named groups are used, there may be more than one
-group with the same name. In this case, a reference to such a group by name
-generates OP_DNREF or OP_DNREFI. These are followed by two counts: the index
-(not the byte offset) in the group name table of the first entry for the
-required name, followed by the number of groups with the same name. The
-matching code can then search for the first one that is set.
-
-
-Repeating character classes and back references
------------------------------------------------
-
-Single-character classes are handled specially (see above). This section
-applies to other classes and also to back references. In both cases, the repeat
-information follows the base item. The matching code looks at the following
-opcode to see if it is one of these:
-
-  OP_CRSTAR
-  OP_CRMINSTAR
-  OP_CRPOSSTAR
-  OP_CRPLUS
-  OP_CRMINPLUS
-  OP_CRPOSPLUS
-  OP_CRQUERY
-  OP_CRMINQUERY
-  OP_CRPOSQUERY
-  OP_CRRANGE
-  OP_CRMINRANGE
-  OP_CRPOSRANGE
-
-All but the last three are single-code-unit items, with no data. The range
-opcodes are followed by the minimum and maximum repeat counts.
-
-
-Brackets and alternation
-------------------------
-
-A pair of non-capturing round brackets is wrapped round each expression at
-compile time, so alternation always happens in the context of brackets.
-
-[Note for North Americans: "bracket" to some English speakers, including
-myself, can be round, square, curly, or pointy. Hence this usage rather than
-"parentheses".]
-
-Non-capturing brackets use the opcode OP_BRA, capturing brackets use OP_CBRA. A
-bracket opcode is followed by a LINK_SIZE value which gives the offset to the
-next alternative OP_ALT or, if there aren't any branches, to the terminating
-opcode. Each OP_ALT is followed by a LINK_SIZE value giving the offset to the
-next one, or to the final opcode. For capturing brackets, the bracket number is
-a count that immediately follows the offset.
-
-There are several opcodes that mark the end of a subpattern group. OP_KET is
-used for subpatterns that do not repeat indefinitely, OP_KETRMIN and
-OP_KETRMAX are used for indefinite repetitions, minimally or maximally
-respectively, and OP_KETRPOS for possessive repetitions (see below for more 
-details). All four are followed by a LINK_SIZE value giving (as a positive
-number) the offset back to the matching bracket opcode.
-
-If a subpattern is quantified such that it is permitted to match zero times, it
-is preceded by one of OP_BRAZERO, OP_BRAMINZERO, or OP_SKIPZERO. These are
-single-unit opcodes that tell the matcher that skipping the following
-subpattern entirely is a valid match. In the case of the first two, not
-skipping the pattern is also valid (greedy and non-greedy). The third is used
-when a pattern has the quantifier {0,0}. It cannot be entirely discarded,
-because it may be called as a subroutine from elsewhere in the pattern.
-
-A subpattern with an indefinite maximum repetition is replicated in the
-compiled data its minimum number of times (or once with OP_BRAZERO if the
-minimum is zero), with the final copy terminating with OP_KETRMIN or OP_KETRMAX
-as appropriate.
-
-A subpattern with a bounded maximum repetition is replicated in a nested
-fashion up to the maximum number of times, with OP_BRAZERO or OP_BRAMINZERO
-before each replication after the minimum, so that, for example, (abc){2,5} is
-compiled as (abc)(abc)((abc)((abc)(abc)?)?)?, except that each bracketed group
-has the same number.
-
-When a repeated subpattern has an unbounded upper limit, it is checked to see
-whether it could match an empty string. If this is the case, the opcode in the
-final replication is changed to OP_SBRA or OP_SCBRA. This tells the matcher
-that it needs to check for matching an empty string when it hits OP_KETRMIN or
-OP_KETRMAX, and if so, to break the loop.
-
-
-Possessive brackets
--------------------
-
-When a repeated group (capturing or non-capturing) is marked as possessive by
-the "+" notation, e.g. (abc)++, different opcodes are used. Their names all
-have POS on the end, e.g. OP_BRAPOS instead of OP_BRA and OP_SCBRAPOS instead
-of OP_SCBRA. The end of such a group is marked by OP_KETRPOS. If the minimum
-repetition is zero, the group is preceded by OP_BRAPOSZERO.
-
-
-Once-only (atomic) groups
--------------------------
-
-These are just like other subpatterns, but they start with the opcode OP_ONCE.
-The check for matching an empty string in an unbounded repeat is handled
-entirely at runtime, so there is just this one opcode for atomic groups.
-
-
-Assertions
-----------
-
-Forward assertions are also just like other subpatterns, but starting with one
-of the opcodes OP_ASSERT, OP_ASSERT_NA (non-atomic assertion), or
-OP_ASSERT_NOT. Backward assertions use the opcodes OP_ASSERTBACK, 
-OP_ASSERTBACK_NA, and OP_ASSERTBACK_NOT, and the first opcode inside the
-assertion is OP_REVERSE, followed by a count of the number of characters to
-move back the pointer in the subject string. In ASCII or UTF-32 mode, the count
-is also the number of code units, but in UTF-8/16 mode each character may
-occupy more than one code unit. A separate count is present in each alternative
-of a lookbehind assertion, allowing each branch to have a different (but fixed)
-length.
-
-
-Conditional subpatterns
------------------------
-
-These are like other subpatterns, but they start with the opcode OP_COND, or
-OP_SCOND for one that might match an empty string in an unbounded repeat.
-
-If the condition is a back reference, this is stored at the start of the
-subpattern using the opcode OP_CREF followed by a count containing the
-reference number, provided that the reference is to a unique capturing group.
-If the reference was by name and there is more than one group with that name,
-OP_DNCREF is used instead. It is followed by two counts: the index in the group
-names table, and the number of groups with the same name. The allows the
-matcher to check if any group with the given name is set.
-
-If the condition is "in recursion" (coded as "(?(R)"), or "in recursion of
-group x" (coded as "(?(Rx)"), the group number is stored at the start of the
-subpattern using the opcode OP_RREF (with a value of RREF_ANY (0xffff) for "the
-whole pattern") or OP_DNRREF (with data as for OP_DNCREF).
-
-For a DEFINE condition, OP_FALSE is used (with no associated data). During
-compilation, however, a DEFINE condition is coded as OP_DEFINE so that, when
-the conditional group is complete, there can be a check to ensure that it
-contains only one top-level branch. Once this has happened, the opcode is
-changed to OP_FALSE, so the matcher never sees OP_DEFINE.
-
-There is a special PCRE2-specific condition of the form (VERSION[>]=x.y), which
-tests the PCRE2 version number. This compiles into one of the opcodes OP_TRUE
-or OP_FALSE.
-
-If a condition is not a back reference, recursion test, DEFINE, or VERSION, it
-must start with a parenthesized atomic assertion, whose opcode normally
-immediately follows OP_COND or OP_SCOND. However, if automatic callouts are
-enabled, a callout is inserted immediately before the assertion. It is also
-possible to insert a manual callout at this point. Only assertion conditions
-may have callouts preceding the condition.
-
-A condition that is the negative assertion (?!) is optimized to OP_FAIL in all
-parts of the pattern, so this is another opcode that may appear as a condition.
-It is treated the same as OP_FALSE.
-
-
-Recursion
----------
-
-Recursion either matches the current pattern, or some subexpression. The opcode
-OP_RECURSE is followed by a LINK_SIZE value that is the offset to the starting
-bracket from the start of the whole pattern. OP_RECURSE is also used for
-"subroutine" calls, even though they are not strictly a recursion. Up till
-release 10.30 recursions were treated as atomic groups, making them
-incompatible with Perl (but PCRE had them well before Perl did). From 10.30,
-backtracking into recursions is supported.
-
-Repeated recursions used to be wrapped inside OP_ONCE brackets, which not only
-forced no backtracking, but also allowed repetition to be handled as for other
-bracketed groups. From 10.30 onwards, repeated recursions are duplicated for
-their minimum repetitions, and then wrapped in non-capturing brackets for the
-remainder. For example, (?1){3} is treated as (?1)(?1)(?1), and (?1){2,4} is
-treated as (?1)(?1)(?:(?1)){0,2}.
-
-
-Callouts
---------
-
-A callout may have either a numerical argument or a string argument. These use
-OP_CALLOUT or OP_CALLOUT_STR, respectively. In each case these are followed by
-two LINK_SIZE values giving the offset in the pattern string to the start of
-the following item, and another count giving the length of this item. These
-values make it possible for pcre2test to output useful tracing information
-using callouts.
-
-In the case of a numeric callout, after these two values there is a single code
-unit containing the callout number, in the range 0-255, with 255 being used for
-callouts that are automatically inserted as a result of the PCRE2_AUTO_CALLOUT
-option. Thus, this opcode item is of fixed length:
-
-  [OP_CALLOUT] [PATTERN_OFFSET] [PATTERN_LENGTH] [NUMBER]
-
-For callouts with string arguments, OP_CALLOUT_STR has three more data items:
-a LINK_SIZE value giving the complete length of the entire opcode item, a
-LINK_SIZE item containing the offset within the pattern string to the start of
-the string argument, and the string itself, preceded by its starting delimiter
-and followed by a binary zero. When a callout function is called, a pointer to
-the actual string is passed, but the delimiter can be accessed as string[-1] if
-the application needs it. In the 8-bit library, the callout in /X(?C'abc')Y/ is
-compiled as the following bytes (decimal numbers represent binary values):
-
-  [OP_CALLOUT_STR]  [0] [10]  [0] [1]  [0] [14]  [0] [5] ['] [a] [b] [c] [0]
-                    --------  -------  --------  -------
-                       |         |        |         |
-                       ------- LINK_SIZE items ------
-
-Opcode table checking
----------------------
-
-The last opcode that is defined in pcre2_internal.h is OP_TABLE_LENGTH. This is
-not a real opcode, but is used to check at compile time that tables indexed by
-opcode are the correct length, in order to catch updating errors.

-News about PCRE2 releases
--------------------------
-
-
-Version 10.37 26-May-2021
--------------------------
-
-A few more bug fixes and tidies. The only change of real note is the removal of
-the actual POSIX names regcomp etc. from the POSIX wrapper library because
-these have caused issues for some applications (see 10.33 #2 below).
-
-
-Version 10.36 04-December-2020
-------------------------------
-
-Again, mainly bug fixes and tidies. The only enhancements are the addition of
-GNU grep's -m (aka --max-count) option to pcre2grep, and also unifying the
-handling of substitution strings for both -O and callouts in pcre2grep, with
-the addition of $x{...} and $o{...} to allow for characters whose code points
-are greater than 255 in Unicode mode.
-
-NOTE: there is an outstanding issue with JIT support for MacOS on arm64
-hardware. For details, please see Bugzilla issue #2618.
-
-
-Version 10.35 15-April-2020
----------------------------
-
-Bugfixes, tidies, and a few new enhancements.
-
-1. Capturing groups that contain recursive backreferences to themselves are no
-longer automatically atomic, because the restriction is no longer necessary
-as a result of the 10.30 restructuring.
-
-2. Several new options for pcre2_substitute().
-
-3. When Unicode is supported and PCRE2_UCP is set without PCRE2_UTF, Unicode
-character properties are used for upper/lower case computations on characters
-whose code points are greater than 127.
-
-4. The character tables (for low-valued characters) can now more easily be
-saved and restored in binary.
-
-5. Updated to Unicode 13.0.0.
-
-
-Version 10.34 21-November-2019
-------------------------------
-
-Another release with a few enhancements as well as bugfixes and tidies. The
-main new features are:
-
-1. There is now some support for matching in invalid UTF strings.
-
-2. Non-atomic positive lookarounds are implemented in the pcre2_match()
-interpreter, but not in JIT.
-
-3. Added two new functions: pcre2_get_match_data_size() and
-pcre2_maketables_free().
-
-4. Upgraded to Unicode 12.1.0.
-
-
-Version 10.33 16-April-2019
----------------------------
-
-Yet more bugfixes, tidies, and a few enhancements, summarized here (see
-ChangeLog for the full list):
-
-1. Callouts from pcre2_substitute() are now available.
-
-2. The POSIX functions are now all called pcre2_regcomp() etc., with wrapper
-functions that use the standard POSIX names. However, in pcre2posix.h the POSIX
-names are defined as macros. This should help avoid linking with the wrong
-library in some environments, while still exporting the POSIX names for
-pre-existing programs that use them.
-
-3. Some new options:
-
-   (a) PCRE2_EXTRA_ESCAPED_CR_IS_LF makes \r behave as \n.
-
-   (b) PCRE2_EXTRA_ALT_BSUX enables support for ECMAScript 6's \u{hh...}
-       construct.
-
-   (c) PCRE2_COPY_MATCHED_SUBJECT causes a copy of a matched subject to be
-       made, instead of just remembering a pointer.
-
-4. Some new Perl features:
-
-   (a) Perl 5.28's experimental alphabetic names for atomic groups and
-       lookaround assertions, for example, (*pla:...) and (*atomic:...).
-
-   (b) The new Perl "script run" features (*script_run:...) and
-       (*atomic_script_run:...) aka (*sr:...) and (*asr:...).
-
-   (c) When PCRE2_UTF is set, allow non-ASCII letters and decimal digits in
-       capture group names.
-
-5. --disable-percent-zt disables the use of %zu and %td in formatting strings
-in pcre2test. They were already automatically disabled for VC and older C
-compilers.
-
-6. Some changes related to callouts in pcre2grep:
-
-   (a) Support for running an external program under VMS has been added, in
-       addition to Windows and fork() support.
-
-   (b) --disable-pcre2grep-callout-fork restricts the callout support in
-       to the inbuilt echo facility.
-
-
-Version 10.32 10-September-2018
--------------------------------
-
-This is another mainly bugfix and tidying release with a few minor
-enhancements. These are the main ones:
-
-1. pcre2grep now supports the inclusion of binary zeros in patterns that are
-read from files via the -f option.
-
-2. ./configure now supports --enable-jit=auto, which automatically enables JIT
-if the hardware supports it.
-
-3. In pcre2_dfa_match(), internal recursive calls no longer use the stack for
-local workspace and local ovectors. Instead, an initial block of stack is
-reserved, but if this is insufficient, heap memory is used. The heap limit
-parameter now applies to pcre2_dfa_match().
-
-4. Updated to Unicode version 11.0.0.
-
-5. (*ACCEPT:ARG), (*FAIL:ARG), and (*COMMIT:ARG) are now supported.
-
-6. Added support for \N{U+dddd}, but only in Unicode mode.
-
-7. Added support for (?^) to unset all imnsx options.
-
-
-Version 10.31 12-February-2018
-------------------------------
-
-This is mainly a bugfix and tidying release (see ChangeLog for full details).
-However, there are some minor enhancements.
-
-1. New pcre2_config() options: PCRE2_CONFIG_NEVER_BACKSLASH_C and
-PCRE2_CONFIG_COMPILED_WIDTHS.
-
-2. New pcre2_pattern_info() option PCRE2_INFO_EXTRAOPTIONS to retrieve the
-extra compile time options.
-
-3. There are now public names for all the pcre2_compile() error numbers.
-
-4. Added PCRE2_CALLOUT_STARTMATCH and PCRE2_CALLOUT_BACKTRACK bits to a new
-field callout_flags in callout blocks.
-
-
-Version 10.30 14-August-2017
-----------------------------
-
-The full list of changes that includes bugfixes and tidies is, as always, in
-ChangeLog. These are the most important new features:
-
-1. The main interpreter, pcre2_match(), has been refactored into a new version
-that does not use recursive function calls (and therefore the system stack) for
-remembering backtracking positions. This makes --disable-stack-for-recursion a
-NOOP. The new implementation allows backtracking into recursive group calls in
-patterns, making it more compatible with Perl, and also fixes some other
-previously hard-to-do issues. For patterns that have a lot of backtracking, the
-heap is now used, and there is an explicit limit on the amount, settable by
-pcre2_set_heap_limit() or (*LIMIT_HEAP=xxx). The "recursion limit" is retained,
-but is renamed as "depth limit" (though the old names remain for
-compatibility).
-
-There is also a change in the way callouts from pcre2_match() are handled. The
-offset_vector field in the callout block is no longer a pointer to the
-actual ovector that was passed to the matching function in the match data
-block. Instead it points to an internal ovector of a size large enough to hold
-all possible captured substrings in the pattern.
-
-2. The new option PCRE2_ENDANCHORED insists that a pattern match must end at
-the end of the subject.
-
-3. The new option PCRE2_EXTENDED_MORE implements Perl's /xx feature, and
-pcre2test is upgraded to support it. Setting within the pattern by (?xx) is
-also supported.
-
-4. (?n) can be used to set PCRE2_NO_AUTO_CAPTURE, because Perl now has this.
-
-5. Additional compile options in the compile context are now available, and the
-first two are: PCRE2_EXTRA_ALLOW_SURROGATE_ESCAPES and
-PCRE2_EXTRA_BAD_ESCAPE_IS_LITERAL.
-
-6. The newline type PCRE2_NEWLINE_NUL is now available.
-
-7. The match limit value now also applies to pcre2_dfa_match() as there are
-patterns that can use up a lot of resources without necessarily recursing very
-deeply.
-
-8. The option REG_PEND (a GNU extension) is now available for the POSIX
-wrapper. Also there is a new option PCRE2_LITERAL which is used to support
-REG_NOSPEC.
-
-9. PCRE2_EXTRA_MATCH_LINE and PCRE2_EXTRA_MATCH_WORD are implemented for the
-benefit of pcre2grep, and pcre2grep's -F, -w, and -x options are re-implemented
-using PCRE2_LITERAL, PCRE2_EXTRA_MATCH_WORD, and PCRE2_EXTRA_MATCH_LINE. This
-is tidier and also fixes some bugs.
-
-10. The Unicode tables are upgraded from Unicode 8.0.0 to Unicode 10.0.0.
-
-11. There are some experimental functions for converting foreign patterns
-(globs and POSIX patterns) into PCRE2 patterns.
-
-
-Version 10.23 14-February-2017
-------------------------------
-
-1. ChangeLog has the details of a lot of bug fixes and tidies.
-
-2. There has been a major re-factoring of the pcre2_compile.c file. Most syntax
-checking is now done in the pre-pass that identifies capturing groups. This has
-reduced the amount of duplication and made the code tidier. While doing this,
-some minor bugs and Perl incompatibilities were fixed (see ChangeLog for
-details.)
-
-3. Back references are now permitted in lookbehind assertions when there are
-no duplicated group numbers (that is, (?| has not been used), and, if the
-reference is by name, there is only one group of that name. The referenced
-group must, of course be of fixed length.
-
-4. \g{+<number>} (e.g. \g{+2} ) is now supported. It is a "forward back
-reference" and can be useful in repetitions (compare \g{-<number>} ). Perl does
-not recognize this syntax.
-
-5. pcre2grep now automatically expands its buffer up to a maximum set by
---max-buffer-size.
-
-6. The -t option (grand total) has been added to pcre2grep.
-
-7. A new function called pcre2_code_copy_with_tables() exists to copy a
-compiled pattern along with a private copy of the character tables that is
-uses.
-
-8. A user supplied a number of patches to upgrade pcre2grep under Windows and
-tidy the code.
-
-9. Several updates have been made to pcre2test and test scripts (see
-ChangeLog).
-
-
-Version 10.22 29-July-2016
---------------------------
-
-1. ChangeLog has the details of a number of bug fixes.
-
-2. The POSIX wrapper function regcomp() did not used to support back references
-and subroutine calls if called with the REG_NOSUB option. It now does.
-
-3. A new function, pcre2_code_copy(), is added, to make a copy of a compiled
-pattern.
-
-4. Support for string callouts is added to pcre2grep.
-
-5. Added the PCRE2_NO_JIT option to pcre2_match().
-
-6. The pcre2_get_error_message() function now returns with a negative error
-code if the error number it is given is unknown.
-
-7. Several updates have been made to pcre2test and test scripts (see
-ChangeLog).
-
-
-Version 10.21 12-January-2016
------------------------------
-
-1. Many bugs have been fixed. A large number of them were provoked only by very
-strange pattern input, and were discovered by fuzzers. Some others were
-discovered by code auditing. See ChangeLog for details.
-
-2. The Unicode tables have been updated to Unicode version 8.0.0.
-
-3. For Perl compatibility in EBCDIC environments, ranges such as a-z in a
-class, where both values are literal letters in the same case, omit the
-non-letter EBCDIC code points within the range.
-
-4. There have been a number of enhancements to the pcre2_substitute() function,
-giving more flexibility to replacement facilities. It is now also possible to
-cause the function to return the needed buffer size if the one given is too
-small.
-
-5. The PCRE2_ALT_VERBNAMES option causes the "name" parts of special verbs such
-as (*THEN:name) to be processed for backslashes and to take note of
-PCRE2_EXTENDED.
-
-6. PCRE2_INFO_HASBACKSLASHC makes it possible for a client to find out if a
-pattern uses \C, and --never-backslash-C makes it possible to compile a version
-PCRE2 in which the use of \C is always forbidden.
-
-7. A limit to the length of pattern that can be handled can now be set by
-calling pcre2_set_max_pattern_length().
-
-8. When matching an unanchored pattern, a match can be required to begin within
-a given number of code units after the start of the subject by calling
-pcre2_set_offset_limit().
-
-9. The pcre2test program has been extended to test new facilities, and it can
-now run the tests when LF on its own is not a valid newline sequence.
-
-10. The RunTest script has also been updated to enable more tests to be run.
-
-11. There have been some minor performance enhancements.
-
-
-Version 10.20 30-June-2015
---------------------------
-
-1. Callouts with string arguments and the pcre2_callout_enumerate() function
-have been implemented.
-
-2. The PCRE2_NEVER_BACKSLASH_C option, which locks out the use of \C, is added.
-
-3. The PCRE2_ALT_CIRCUMFLEX option lets ^ match after a newline at the end of a
-subject in multiline mode.
-
-4. The way named subpatterns are handled has been refactored. The previous
-approach had several bugs.
-
-5. The handling of \c in EBCDIC environments has been changed to conform to the
-perlebcdic document. This is an incompatible change.
-
-6. Bugs have been mended, many of them discovered by fuzzers.
-
-
-Version 10.10 06-March-2015
----------------------------
-
-1. Serialization and de-serialization functions have been added to the API,
-making it possible to save and restore sets of compiled patterns, though
-restoration must be done in the same environment that was used for compilation.
-
-2. The (*NO_JIT) feature has been added; this makes it possible for a pattern
-creator to specify that JIT is not to be used.
-
-3. A number of bugs have been fixed. In particular, bugs that caused building
-on Windows using CMake to fail have been mended.
-
-
-Version 10.00 05-January-2015
------------------------------
-
-Version 10.00 is the first release of PCRE2, a revised API for the PCRE
-library. Changes prior to 10.00 are logged in the ChangeLog file for the old
-API, up to item 20 for release 8.36. New programs are recommended to use the
-new library. Programs that use the original (PCRE1) API will need changing
-before linking with the new library.

-Building PCRE2 without using autotools
---------------------------------------
-
-This document contains the following sections:
-
-  General
-  Generic instructions for the PCRE2 C library
-  Stack size in Windows environments
-  Linking programs in Windows environments
-  Calling conventions in Windows environments
-  Comments about Win32 builds
-  Building PCRE2 on Windows with CMake
-  Building PCRE2 on Windows with Visual Studio
-  Testing with RunTest.bat
-  Building PCRE2 on native z/OS and z/VM
-
-
-GENERAL
-
-The basic PCRE2 library consists entirely of code written in Standard C, and so
-should compile successfully on any system that has a Standard C compiler and
-library.
-
-The PCRE2 distribution includes a "configure" file for use by the
-configure/make (autotools) build system, as found in many Unix-like
-environments. The README file contains information about the options for
-"configure".
-
-There is also support for CMake, which some users prefer, especially in Windows
-environments, though it can also be run in Unix-like environments. See the
-section entitled "Building PCRE2 on Windows with CMake" below.
-
-Versions of src/config.h and src/pcre2.h are distributed in the PCRE2 tarballs
-under the names src/config.h.generic and src/pcre2.h.generic. These are
-provided for those who build PCRE2 without using "configure" or CMake. If you
-use "configure" or CMake, the .generic versions are not used.
-
-
-GENERIC INSTRUCTIONS FOR THE PCRE2 C LIBRARY
-
-The following are generic instructions for building the PCRE2 C library "by
-hand". If you are going to use CMake, this section does not apply to you; you
-can skip ahead to the CMake section. Note that the settings concerned with
-8-bit, 16-bit, and 32-bit code units relate to the type of data string that
-PCRE2 processes. They are NOT referring to the underlying operating system bit
-width. You do not have to do anything special to compile in a 64-bit
-environment, for example.
-
- (1) Copy or rename the file src/config.h.generic as src/config.h, and edit the
-     macro settings that it contains to whatever is appropriate for your
-     environment. In particular, you can alter the definition of the NEWLINE
-     macro to specify what character(s) you want to be interpreted as line
-     terminators by default.
-
-     When you subsequently compile any of the PCRE2 modules, you must specify
-     -DHAVE_CONFIG_H to your compiler so that src/config.h is included in the
-     sources.
-
-     An alternative approach is not to edit src/config.h, but to use -D on the
-     compiler command line to make any changes that you need to the
-     configuration options. In this case -DHAVE_CONFIG_H must not be set.
-
-     NOTE: There have been occasions when the way in which certain parameters
-     in src/config.h are used has changed between releases. (In the
-     configure/make world, this is handled automatically.) When upgrading to a
-     new release, you are strongly advised to review src/config.h.generic
-     before re-using what you had previously.
-
-     Note also that the src/config.h.generic file is created from a config.h
-     that was generated by Autotools, which automatically includes settings of
-     a number of macros that are not actually used by PCRE2 (for example,
-     HAVE_MEMORY_H).
-
- (2) Copy or rename the file src/pcre2.h.generic as src/pcre2.h.
-
- (3) EITHER:
-       Copy or rename file src/pcre2_chartables.c.dist as
-       src/pcre2_chartables.c.
-
-     OR:
-       Compile src/pcre2_dftables.c as a stand-alone program (using
-       -DHAVE_CONFIG_H if you have set up src/config.h), and then run it with
-       the single argument "src/pcre2_chartables.c". This generates a set of
-       standard character tables and writes them to that file. The tables are
-       generated using the default C locale for your system. If you want to use
-       a locale that is specified by LC_xxx environment variables, add the -L
-       option to the pcre2_dftables command. You must use this method if you
-       are building on a system that uses EBCDIC code.
-
-     The tables in src/pcre2_chartables.c are defaults. The caller of PCRE2 can
-     specify alternative tables at run time.
-
- (4) For a library that supports 8-bit code units in the character strings that
-     it processes, compile the following source files from the src directory,
-     setting -DPCRE2_CODE_UNIT_WIDTH=8 as a compiler option. Also set
-     -DHAVE_CONFIG_H if you have set up src/config.h with your configuration,
-     or else use other -D settings to change the configuration as required.

-       pcre2_chartables.c
-       pcre2_compile.c
-       pcre2_config.c

-
-     Make sure that you include -I. in the compiler command (or equivalent for
-     an unusual compiler) so that all included PCRE2 header files are first
-     sought in the src directory under the current directory. Otherwise you run
-     the risk of picking up a previously-installed file from somewhere else.
-
-     Note that you must compile pcre2_jit_compile.c, even if you have not
-     defined SUPPORT_JIT in src/config.h, because when JIT support is not
-     configured, dummy functions are compiled. When JIT support IS configured,
-     pcre2_jit_compile.c #includes other files from the sljit subdirectory,
-     all of whose names begin with "sljit". It also #includes
-     src/pcre2_jit_match.c and src/pcre2_jit_misc.c, so you should not compile
-     these yourself.
-
-     Note also that the pcre2_fuzzsupport.c file contains special code that is
-     useful to those who want to run fuzzing tests on the PCRE2 library. Unless
-     you are doing that, you can ignore it.
-
- (5) Now link all the compiled code into an object library in whichever form
-     your system keeps such libraries. This is the basic PCRE2 C 8-bit library.
-     If your system has static and shared libraries, you may have to do this
-     once for each type.
-
- (6) If you want to build a library that supports 16-bit or 32-bit code units,
-     (as well as, or instead of the 8-bit library) just supply 16 or 32 as the
-     value of -DPCRE2_CODE_UNIT_WIDTH when you are compiling.
-
- (7) If you want to build the POSIX wrapper functions (which apply only to the
-     8-bit library), ensure that you have the src/pcre2posix.h file and then
-     compile src/pcre2posix.c. Link the result (on its own) as the pcre2posix
-     library.
-
- (8) The pcre2test program can be linked with any combination of the 8-bit,
-     16-bit and 32-bit libraries (depending on what you selected in
-     src/config.h). Compile src/pcre2test.c; don't forget -DHAVE_CONFIG_H if
-     necessary, but do NOT define PCRE2_CODE_UNIT_WIDTH. Then link with the
-     appropriate library/ies. If you compiled an 8-bit library, pcre2test also
-     needs the pcre2posix wrapper library.
-
- (9) Run pcre2test on the testinput files in the testdata directory, and check
-     that the output matches the corresponding testoutput files. There are
-     comments about what each test does in the section entitled "Testing PCRE2"
-     in the README file. If you compiled more than one of the 8-bit, 16-bit and
-     32-bit libraries, you need to run pcre2test with the -16 option to do
-     16-bit tests and with the -32 option to do 32-bit tests.
-
-     Some tests are relevant only when certain build-time options are selected.
-     For example, test 4 is for Unicode support, and will not run if you have
-     built PCRE2 without it. See the comments at the start of each testinput
-     file. If you have a suitable Unix-like shell, the RunTest script will run
-     the appropriate tests for you. The command "RunTest list" will output a
-     list of all the tests.
-
-     Note that the supplied files are in Unix format, with just LF characters
-     as line terminators. You may need to edit them to change this if your
-     system uses a different convention.
-
-(10) If you have built PCRE2 with SUPPORT_JIT, the JIT features can be tested
-     by running pcre2test with the -jit option. This is done automatically by
-     the RunTest script. You might also like to build and run the freestanding
-     JIT test program, src/pcre2_jit_test.c.
-
-(11) If you want to use the pcre2grep command, compile and link
-     src/pcre2grep.c; it uses only the basic 8-bit PCRE2 library (it does not
-     need the pcre2posix library). If you have built the PCRE2 library with JIT
-     support by defining SUPPORT_JIT in src/config.h, you can also define
-     SUPPORT_PCRE2GREP_JIT, which causes pcre2grep to make use of JIT (unless
-     it is run with --no-jit). If you define SUPPORT_PCRE2GREP_JIT without
-     defining SUPPORT_JIT, pcre2grep does not try to make use of JIT.
-
-
-STACK SIZE IN WINDOWS ENVIRONMENTS
-
-Prior to release 10.30 the default system stack size of 1MiB in some Windows
-environments caused issues with some tests. This should no longer be the case
-for 10.30 and later releases.
-
-
-LINKING PROGRAMS IN WINDOWS ENVIRONMENTS
-
-If you want to statically link a program against a PCRE2 library in the form of
-a non-dll .a file, you must define PCRE2_STATIC before including src/pcre2.h.
-
-
-CALLING CONVENTIONS IN WINDOWS ENVIRONMENTS
-
-It is possible to compile programs to use different calling conventions using
-MSVC. Search the web for "calling conventions" for more information. To make it
-easier to change the calling convention for the exported functions in the
-PCRE2 library, the macro PCRE2_CALL_CONVENTION is present in all the external
-definitions. It can be set externally when compiling (e.g. in CFLAGS). If it is
-not set, it defaults to empty; the default calling convention is then used
-(which is what is wanted most of the time).
-
-
-COMMENTS ABOUT WIN32 BUILDS (see also "BUILDING PCRE2 ON WINDOWS WITH CMAKE")
-
-There are two ways of building PCRE2 using the "configure, make, make install"
-paradigm on Windows systems: using MinGW or using Cygwin. These are not at all
-the same thing; they are completely different from each other. There is also
-support for building using CMake, which some users find a more straightforward
-way of building PCRE2 under Windows.
-
-The MinGW home page (http://www.mingw.org/) says this:
-
-  MinGW: A collection of freely available and freely distributable Windows
-  specific header files and import libraries combined with GNU toolsets that
-  allow one to produce native Windows programs that do not rely on any
-  3rd-party C runtime DLLs.
-
-The Cygwin home page (http://www.cygwin.com/) says this:
-
-  Cygwin is a Linux-like environment for Windows. It consists of two parts:
-
-  . A DLL (cygwin1.dll) which acts as a Linux API emulation layer providing
-    substantial Linux API functionality
-
-  . A collection of tools which provide Linux look and feel.
-
-On both MinGW and Cygwin, PCRE2 should build correctly using:
-
-  ./configure && make && make install
-
-This should create two libraries called libpcre2-8 and libpcre2-posix. These
-are independent libraries: when you link with libpcre2-posix you must also link
-with libpcre2-8, which contains the basic functions.
-
-Using Cygwin's compiler generates libraries and executables that depend on
-cygwin1.dll. If a library that is generated this way is distributed,
-cygwin1.dll has to be distributed as well. Since cygwin1.dll is under the GPL
-licence, this forces not only PCRE2 to be under the GPL, but also the entire
-application. A distributor who wants to keep their own code proprietary must
-purchase an appropriate Cygwin licence.
-
-MinGW has no such restrictions. The MinGW compiler generates a library or
-executable that can run standalone on Windows without any third party dll or
-licensing issues.
-
-But there is more complication:
-
-If a Cygwin user uses the -mno-cygwin Cygwin gcc flag, what that really does is
-to tell Cygwin's gcc to use the MinGW gcc. Cygwin's gcc is only acting as a
-front end to MinGW's gcc (if you install Cygwin's gcc, you get both Cygwin's
-gcc and MinGW's gcc). So, a user can:
-
-. Build native binaries by using MinGW or by getting Cygwin and using
-  -mno-cygwin.
-
-. Build binaries that depend on cygwin1.dll by using Cygwin with the normal
-  compiler flags.
-
-The test files that are supplied with PCRE2 are in UNIX format, with LF
-characters as line terminators. Unless your PCRE2 library uses a default
-newline option that includes LF as a valid newline, it may be necessary to
-change the line terminators in the test files to get some of the tests to work.
-
-
-BUILDING PCRE2 ON WINDOWS WITH CMAKE
-
-CMake is an alternative configuration facility that can be used instead of
-"configure". CMake creates project files (make files, solution files, etc.)
-tailored to numerous development environments, including Visual Studio,
-Borland, Msys, MinGW, NMake, and Unix. If possible, use short paths with no
-spaces in the names for your CMake installation and your PCRE2 source and build
-directories.
-
-The following instructions were contributed by a PCRE1 user, but they should
-also work for PCRE2. If they are not followed exactly, errors may occur. In the
-event that errors do occur, it is recommended that you delete the CMake cache
-before attempting to repeat the CMake build process. In the CMake GUI, the
-cache can be deleted by selecting "File > Delete Cache".
-
-1.  Install the latest CMake version available from http://www.cmake.org/, and
-    ensure that cmake\bin is on your path.
-
-2.  Unzip (retaining folder structure) the PCRE2 source tree into a source
-    directory such as C:\pcre2. You should ensure your local date and time
-    is not earlier than the file dates in your source dir if the release is
-    very new.
-
-3.  Create a new, empty build directory, preferably a subdirectory of the
-    source dir. For example, C:\pcre2\pcre2-xx\build.
-
-4.  Run cmake-gui from the Shell envirornment of your build tool, for example,
-    Msys for Msys/MinGW or Visual Studio Command Prompt for VC/VC++. Do not try
-    to start Cmake from the Windows Start menu, as this can lead to errors.
-
-5.  Enter C:\pcre2\pcre2-xx and C:\pcre2\pcre2-xx\build for the source and
-    build directories, respectively.
-
-6.  Hit the "Configure" button.
-
-7.  Select the particular IDE / build tool that you are using (Visual
-    Studio, MSYS makefiles, MinGW makefiles, etc.)
-
-8.  The GUI will then list several configuration options. This is where
-    you can disable Unicode support or select other PCRE2 optional features.
-
-9.  Hit "Configure" again. The adjacent "Generate" button should now be
-    active.
-
-10. Hit "Generate".
-
-11. The build directory should now contain a usable build system, be it a
-    solution file for Visual Studio, makefiles for MinGW, etc. Exit from
-    cmake-gui and use the generated build system with your compiler or IDE.
-    E.g., for MinGW you can run "make", or for Visual Studio, open the PCRE2
-    solution, select the desired configuration (Debug, or Release, etc.) and
-    build the ALL_BUILD project.
-
-12. If during configuration with cmake-gui you've elected to build the test
-    programs, you can execute them by building the test project. E.g., for
-    MinGW: "make test"; for Visual Studio build the RUN_TESTS project. The
-    most recent build configuration is targeted by the tests. A summary of
-    test results is presented. Complete test output is subsequently
-    available for review in Testing\Temporary under your build dir.
-
-
-BUILDING PCRE2 ON WINDOWS WITH VISUAL STUDIO
-
-The code currently cannot be compiled without a stdint.h header, which is
-available only in relatively recent versions of Visual Studio. However, this
-portable and permissively-licensed implementation of the header worked without
-issue:
-
-  http://www.azillionmonkeys.com/qed/pstdint.h
-
-Just rename it and drop it into the top level of the build tree.
-
-
-TESTING WITH RUNTEST.BAT
-
-If configured with CMake, building the test project ("make test" or building
-ALL_TESTS in Visual Studio) creates (and runs) pcre2_test.bat (and depending
-on your configuration options, possibly other test programs) in the build
-directory. The pcre2_test.bat script runs RunTest.bat with correct source and
-exe paths.
-
-For manual testing with RunTest.bat, provided the build dir is a subdirectory
-of the source directory: Open command shell window. Chdir to the location
-of your pcre2test.exe and pcre2grep.exe programs. Call RunTest.bat with
-"..\RunTest.Bat" or "..\..\RunTest.bat" as appropriate.
-
-To run only a particular test with RunTest.Bat provide a test number argument.
-
-Otherwise:
-
-1. Copy RunTest.bat into the directory where pcre2test.exe and pcre2grep.exe
-   have been created.
-
-2. Edit RunTest.bat to indentify the full or relative location of
-   the pcre2 source (wherein which the testdata folder resides), e.g.:
-
-   set srcdir=C:\pcre2\pcre2-10.00
-
-3. In a Windows command environment, chdir to the location of your bat and
-   exe programs.
-
-4. Run RunTest.bat. Test outputs will automatically be compared to expected
-   results, and discrepancies will be identified in the console output.
-
-To independently test the just-in-time compiler, run pcre2_jit_test.exe.
-
-
-BUILDING PCRE2 ON NATIVE Z/OS AND Z/VM
-
-z/OS and z/VM are operating systems for mainframe computers, produced by IBM.
-The character code used is EBCDIC, not ASCII or Unicode. In z/OS, UNIX APIs and
-applications can be supported through UNIX System Services, and in such an
-environment it should be possible to build PCRE2 in the same way as in other
-systems, with the EBCDIC related configuration settings, but it is not known if
-anybody has tried this.
-
-In native z/OS (without UNIX System Services) and in z/VM, special ports are
-required. For details, please see file 939 on this web site:
-
-  http://www.cbttape.org
-
-Everything in that location, source and executable, is in EBCDIC and native
-z/OS file formats. The port provides an API for LE languages such as COBOL and
-for the z/OS and z/VM versions of the Rexx languages.

-README file for PCRE2 (Perl-compatible regular expression library)
-------------------------------------------------------------------
-
-PCRE2 is a re-working of the original PCRE1 library to provide an entirely new
-API. Since its initial release in 2015, there has been further development of
-the code and it now differs from PCRE1 in more than just the API. There are new
-features, and the internals have been improved. The original PCRE1 library is
-now obsolete and should not be used in new projects. The latest release of
-PCRE2 is available in three alternative formats from:
-
-https://ftp.pcre.org/pub/pcre/pcre2-10.xx.tar.gz
-https://ftp.pcre.org/pub/pcre/pcre2-10.xx.tar.bz2
-https://ftp.pcre.org/pub/pcre/pcre2-10.xx.tar.zip
-
-There is a mailing list for discussion about the development of PCRE at
-pcre-dev@exim.org. You can access the archives and subscribe or manage your
-subscription here:

-The PCRE2 APIs
---------------
-
-PCRE2 is written in C, and it has its own API. There are three sets of
-functions, one for the 8-bit library, which processes strings of bytes, one for
-the 16-bit library, which processes strings of 16-bit values, and one for the
-32-bit library, which processes strings of 32-bit values. Unlike PCRE1, there
-are no C++ wrappers.
-
-The distribution does contain a set of C wrapper functions for the 8-bit
-library that are based on the POSIX regular expression API (see the pcre2posix
-man page). These are built into a library called libpcre2-posix. Note that this
-just provides a POSIX calling interface to PCRE2; the regular expressions
-themselves still follow Perl syntax and semantics. The POSIX API is restricted,
-and does not give full access to all of PCRE2's facilities.
-
-The header file for the POSIX-style functions is called pcre2posix.h. The
-official POSIX name is regex.h, but I did not want to risk possible problems
-with existing files of that name by distributing it that way. To use PCRE2 with
-an existing program that uses the POSIX API, pcre2posix.h will have to be
-renamed or pointed at by a link (or the program modified, of course). See the
-pcre2posix documentation for more details.
-
-
-Documentation for PCRE2
------------------------
-
-If you install PCRE2 in the normal way on a Unix-like system, you will end up
-with a set of man pages whose names all start with "pcre2". The one that is
-just called "pcre2" lists all the others. In addition to these man pages, the
-PCRE2 documentation is supplied in two other forms:
-
-  1. There are files called doc/pcre2.txt, doc/pcre2grep.txt, and
-     doc/pcre2test.txt in the source distribution. The first of these is a
-     concatenation of the text forms of all the section 3 man pages except the
-     listing of pcre2demo.c and those that summarize individual functions. The
-     other two are the text forms of the section 1 man pages for the pcre2grep
-     and pcre2test commands. These text forms are provided for ease of scanning
-     with text editors or similar tools. They are installed in
-     <prefix>/share/doc/pcre2, where <prefix> is the installation prefix
-     (defaulting to /usr/local).
-
-  2. A set of files containing all the documentation in HTML form, hyperlinked
-     in various ways, and rooted in a file called index.html, is distributed in
-     doc/html and installed in <prefix>/share/doc/pcre2/html.
-
-
-Building PCRE2 on non-Unix-like systems
----------------------------------------
-
-For a non-Unix-like system, please read the file NON-AUTOTOOLS-BUILD, though if
-your system supports the use of "configure" and "make" you may be able to build
-PCRE2 using autotools in the same way as for many Unix-like systems.
-
-PCRE2 can also be configured using CMake, which can be run in various ways
-(command line, GUI, etc). This creates Makefiles, solution files, etc. The file
-NON-AUTOTOOLS-BUILD has information about CMake.
-
-PCRE2 has been compiled on many different operating systems. It should be
-straightforward to build PCRE2 on any system that has a Standard C compiler and
-library, because it uses only Standard C functions.
-
-
-Building PCRE2 without using autotools
---------------------------------------
-
-The use of autotools (in particular, libtool) is problematic in some
-environments, even some that are Unix or Unix-like. See the NON-AUTOTOOLS-BUILD
-file for ways of building PCRE2 without using autotools.
-
-
-Building PCRE2 using autotools
-------------------------------
-
-The following instructions assume the use of the widely used "configure; make;
-make install" (autotools) process.
-
-To build PCRE2 on system that supports autotools, first run the "configure"
-command from the PCRE2 distribution directory, with your current directory set
-to the directory where you want the files to be created. This command is a
-standard GNU "autoconf" configuration script, for which generic instructions
-are supplied in the file INSTALL.
-
-Most commonly, people build PCRE2 within its own distribution directory, and in
-this case, on many systems, just running "./configure" is sufficient. However,
-the usual methods of changing standard defaults are available. For example:
-
-CFLAGS='-O2 -Wall' ./configure --prefix=/opt/local
-
-This command specifies that the C compiler should be run with the flags '-O2
--Wall' instead of the default, and that "make install" should install PCRE2
-under /opt/local instead of the default /usr/local.
-
-If you want to build in a different directory, just run "configure" with that
-directory as current. For example, suppose you have unpacked the PCRE2 source
-into /source/pcre2/pcre2-xxx, but you want to build it in
-/build/pcre2/pcre2-xxx:
-
-cd /build/pcre2/pcre2-xxx
-/source/pcre2/pcre2-xxx/configure
-
-PCRE2 is written in C and is normally compiled as a C library. However, it is
-possible to build it as a C++ library, though the provided building apparatus
-does not have any features to support this.
-
-There are some optional features that can be included or omitted from the PCRE2
-library. They are also documented in the pcre2build man page.
-
-. By default, both shared and static libraries are built. You can change this
-  by adding one of these options to the "configure" command:
-
-  --disable-shared
-  --disable-static
-
-  (See also "Shared libraries on Unix-like systems" below.)
-
-. By default, only the 8-bit library is built. If you add --enable-pcre2-16 to
-  the "configure" command, the 16-bit library is also built. If you add
-  --enable-pcre2-32 to the "configure" command, the 32-bit library is also
-  built. If you want only the 16-bit or 32-bit library, use --disable-pcre2-8
-  to disable building the 8-bit library.
-
-. If you want to include support for just-in-time (JIT) compiling, which can
-  give large performance improvements on certain platforms, add --enable-jit to
-  the "configure" command. This support is available only for certain hardware
-  architectures. If you try to enable it on an unsupported architecture, there
-  will be a compile time error. If in doubt, use --enable-jit=auto, which
-  enables JIT only if the current hardware is supported.
-
-. If you are enabling JIT under SELinux environment you may also want to add
-  --enable-jit-sealloc, which enables the use of an executable memory allocator
-  that is compatible with SELinux. Warning: this allocator is experimental!
-  It does not support fork() operation and may crash when no disk space is
-  available. This option has no effect if JIT is disabled.
-
-. If you do not want to make use of the default support for UTF-8 Unicode
-  character strings in the 8-bit library, UTF-16 Unicode character strings in
-  the 16-bit library, or UTF-32 Unicode character strings in the 32-bit
-  library, you can add --disable-unicode to the "configure" command. This
-  reduces the size of the libraries. It is not possible to configure one
-  library with Unicode support, and another without, in the same configuration.
-  It is also not possible to use --enable-ebcdic (see below) with Unicode
-  support, so if this option is set, you must also use --disable-unicode.
-
-  When Unicode support is available, the use of a UTF encoding still has to be
-  enabled by setting the PCRE2_UTF option at run time or starting a pattern
-  with (*UTF). When PCRE2 is compiled with Unicode support, its input can only
-  either be ASCII or UTF-8/16/32, even when running on EBCDIC platforms.
-
-  As well as supporting UTF strings, Unicode support includes support for the
-  \P, \p, and \X sequences that recognize Unicode character properties.
-  However, only the basic two-letter properties such as Lu are supported.
-  Escape sequences such as \d and \w in patterns do not by default make use of
-  Unicode properties, but can be made to do so by setting the PCRE2_UCP option
-  or starting a pattern with (*UCP).
-
-. You can build PCRE2 to recognize either CR or LF or the sequence CRLF, or any
-  of the preceding, or any of the Unicode newline sequences, or the NUL (zero)
-  character as indicating the end of a line. Whatever you specify at build time
-  is the default; the caller of PCRE2 can change the selection at run time. The
-  default newline indicator is a single LF character (the Unix standard). You
-  can specify the default newline indicator by adding --enable-newline-is-cr,
-  --enable-newline-is-lf, --enable-newline-is-crlf,
-  --enable-newline-is-anycrlf, --enable-newline-is-any, or
-  --enable-newline-is-nul to the "configure" command, respectively.
-
-. By default, the sequence \R in a pattern matches any Unicode line ending
-  sequence. This is independent of the option specifying what PCRE2 considers
-  to be the end of a line (see above). However, the caller of PCRE2 can
-  restrict \R to match only CR, LF, or CRLF. You can make this the default by
-  adding --enable-bsr-anycrlf to the "configure" command (bsr = "backslash R").
-
-. In a pattern, the escape sequence \C matches a single code unit, even in a
-  UTF mode. This can be dangerous because it breaks up multi-code-unit
-  characters. You can build PCRE2 with the use of \C permanently locked out by
-  adding --enable-never-backslash-C (note the upper case C) to the "configure"
-  command. When \C is allowed by the library, individual applications can lock
-  it out by calling pcre2_compile() with the PCRE2_NEVER_BACKSLASH_C option.
-
-. PCRE2 has a counter that limits the depth of nesting of parentheses in a
-  pattern. This limits the amount of system stack that a pattern uses when it
-  is compiled. The default is 250, but you can change it by setting, for
-  example,
-
-  --with-parens-nest-limit=500
-
-. PCRE2 has a counter that can be set to limit the amount of computing resource
-  it uses when matching a pattern. If the limit is exceeded during a match, the
-  match fails. The default is ten million. You can change the default by
-  setting, for example,
-
-  --with-match-limit=500000
-
-  on the "configure" command. This is just the default; individual calls to
-  pcre2_match() or pcre2_dfa_match() can supply their own value. There is more
-  discussion in the pcre2api man page (search for pcre2_set_match_limit).
-
-. There is a separate counter that limits the depth of nested backtracking
-  (pcre2_match()) or nested function calls (pcre2_dfa_match()) during a
-  matching process, which indirectly limits the amount of heap memory that is
-  used, and in the case of pcre2_dfa_match() the amount of stack as well. This
-  counter also has a default of ten million, which is essentially "unlimited".
-  You can change the default by setting, for example,
-
-  --with-match-limit-depth=5000
-
-  There is more discussion in the pcre2api man page (search for
-  pcre2_set_depth_limit).
-
-. You can also set an explicit limit on the amount of heap memory used by
-  the pcre2_match() and pcre2_dfa_match() interpreters:
-
-  --with-heap-limit=500
-
-  The units are kibibytes (units of 1024 bytes). This limit does not apply when
-  the JIT optimization (which has its own memory control features) is used.
-  There is more discussion on the pcre2api man page (search for
-  pcre2_set_heap_limit).
-
-. In the 8-bit library, the default maximum compiled pattern size is around
-  64 kibibytes. You can increase this by adding --with-link-size=3 to the
-  "configure" command. PCRE2 then uses three bytes instead of two for offsets
-  to different parts of the compiled pattern. In the 16-bit library,
-  --with-link-size=3 is the same as --with-link-size=4, which (in both
-  libraries) uses four-byte offsets. Increasing the internal link size reduces
-  performance in the 8-bit and 16-bit libraries. In the 32-bit library, the
-  link size setting is ignored, as 4-byte offsets are always used.
-
-. For speed, PCRE2 uses four tables for manipulating and identifying characters
-  whose code point values are less than 256. By default, it uses a set of
-  tables for ASCII encoding that is part of the distribution. If you specify
-
-  --enable-rebuild-chartables
-
-  a program called pcre2_dftables is compiled and run in the default C locale
-  when you obey "make". It builds a source file called pcre2_chartables.c. If
-  you do not specify this option, pcre2_chartables.c is created as a copy of
-  pcre2_chartables.c.dist. See "Character tables" below for further
-  information.
-
-. It is possible to compile PCRE2 for use on systems that use EBCDIC as their
-  character code (as opposed to ASCII/Unicode) by specifying
-
-  --enable-ebcdic --disable-unicode
-
-  This automatically implies --enable-rebuild-chartables (see above). However,
-  when PCRE2 is built this way, it always operates in EBCDIC. It cannot support
-  both EBCDIC and UTF-8/16/32. There is a second option, --enable-ebcdic-nl25,
-  which specifies that the code value for the EBCDIC NL character is 0x25
-  instead of the default 0x15.
-
-. If you specify --enable-debug, additional debugging code is included in the
-  build. This option is intended for use by the PCRE2 maintainers.
-
-. In environments where valgrind is installed, if you specify
-
-  --enable-valgrind
-
-  PCRE2 will use valgrind annotations to mark certain memory regions as
-  unaddressable. This allows it to detect invalid memory accesses, and is
-  mostly useful for debugging PCRE2 itself.
-
-. In environments where the gcc compiler is used and lcov is installed, if you
-  specify
-
-  --enable-coverage
-
-  the build process implements a code coverage report for the test suite. The
-  report is generated by running "make coverage". If ccache is installed on
-  your system, it must be disabled when building PCRE2 for coverage reporting.
-  You can do this by setting the environment variable CCACHE_DISABLE=1 before
-  running "make" to build PCRE2. There is more information about coverage
-  reporting in the "pcre2build" documentation.
-
-. When JIT support is enabled, pcre2grep automatically makes use of it, unless
-  you add --disable-pcre2grep-jit to the "configure" command.
-
-. There is support for calling external programs during matching in the
-  pcre2grep command, using PCRE2's callout facility with string arguments. This
-  support can be disabled by adding --disable-pcre2grep-callout to the
-  "configure" command. There are two kinds of callout: one that generates
-  output from inbuilt code, and another that calls an external program. The
-  latter has special support for Windows and VMS; otherwise it assumes the
-  existence of the fork() function. This facility can be disabled by adding
-  --disable-pcre2grep-callout-fork to the "configure" command.
-
-. The pcre2grep program currently supports only 8-bit data files, and so
-  requires the 8-bit PCRE2 library. It is possible to compile pcre2grep to use
-  libz and/or libbz2, in order to read .gz and .bz2 files (respectively), by
-  specifying one or both of
-
-  --enable-pcre2grep-libz
-  --enable-pcre2grep-libbz2
-
-  Of course, the relevant libraries must be installed on your system.
-
-. The default starting size (in bytes) of the internal buffer used by pcre2grep
-  can be set by, for example:
-
-  --with-pcre2grep-bufsize=51200
-
-  The value must be a plain integer. The default is 20480. The amount of memory
-  used by pcre2grep is actually three times this number, to allow for "before"
-  and "after" lines. If very long lines are encountered, the buffer is
-  automatically enlarged, up to a fixed maximum size.
-
-. The default maximum size of pcre2grep's internal buffer can be set by, for
-  example:
-
-  --with-pcre2grep-max-bufsize=2097152
-
-  The default is either 1048576 or the value of --with-pcre2grep-bufsize,
-  whichever is the larger.
-
-. It is possible to compile pcre2test so that it links with the libreadline
-  or libedit libraries, by specifying, respectively,
-
-  --enable-pcre2test-libreadline or --enable-pcre2test-libedit
-
-  If this is done, when pcre2test's input is from a terminal, it reads it using
-  the readline() function. This provides line-editing and history facilities.
-  Note that libreadline is GPL-licenced, so if you distribute a binary of
-  pcre2test linked in this way, there may be licensing issues. These can be
-  avoided by linking with libedit (which has a BSD licence) instead.
-
-  Enabling libreadline causes the -lreadline option to be added to the
-  pcre2test build. In many operating environments with a sytem-installed
-  readline library this is sufficient. However, in some environments (e.g. if
-  an unmodified distribution version of readline is in use), it may be
-  necessary to specify something like LIBS="-lncurses" as well. This is
-  because, to quote the readline INSTALL, "Readline uses the termcap functions,
-  but does not link with the termcap or curses library itself, allowing
-  applications which link with readline the to choose an appropriate library."
-  If you get error messages about missing functions tgetstr, tgetent, tputs,
-  tgetflag, or tgoto, this is the problem, and linking with the ncurses library
-  should fix it.
-
-. The C99 standard defines formatting modifiers z and t for size_t and
-  ptrdiff_t values, respectively. By default, PCRE2 uses these modifiers in
-  environments other than Microsoft Visual Studio when __STDC_VERSION__ is
-  defined and has a value greater than or equal to 199901L (indicating C99).
-  However, there is at least one environment that claims to be C99 but does not
-  support these modifiers. If --disable-percent-zt is specified, no use is made
-  of the z or t modifiers. Instead or %td or %zu, %lu is used, with a cast for
-  size_t values.
-
-. There is a special option called --enable-fuzz-support for use by people who
-  want to run fuzzing tests on PCRE2. At present this applies only to the 8-bit
-  library. If set, it causes an extra library called libpcre2-fuzzsupport.a to
-  be built, but not installed. This contains a single function called
-  LLVMFuzzerTestOneInput() whose arguments are a pointer to a string and the
-  length of the string. When called, this function tries to compile the string
-  as a pattern, and if that succeeds, to match it. This is done both with no
-  options and with some random options bits that are generated from the string.
-  Setting --enable-fuzz-support also causes a binary called pcre2fuzzcheck to
-  be created. This is normally run under valgrind or used when PCRE2 is
-  compiled with address sanitizing enabled. It calls the fuzzing function and
-  outputs information about it is doing. The input strings are specified by
-  arguments: if an argument starts with "=" the rest of it is a literal input
-  string. Otherwise, it is assumed to be a file name, and the contents of the
-  file are the test string.
-
-. Releases before 10.30 could be compiled with --disable-stack-for-recursion,
-  which caused pcre2_match() to use individual blocks on the heap for
-  backtracking instead of recursive function calls (which use the stack). This
-  is now obsolete since pcre2_match() was refactored always to use the heap (in
-  a much more efficient way than before). This option is retained for backwards
-  compatibility, but has no effect other than to output a warning.
-
-The "configure" script builds the following files for the basic C library:
-
-. Makefile             the makefile that builds the library
-. src/config.h         build-time configuration options for the library
-. src/pcre2.h          the public PCRE2 header file
-. pcre2-config          script that shows the building settings such as CFLAGS
-                         that were set for "configure"
-. libpcre2-8.pc        )
-. libpcre2-16.pc       ) data for the pkg-config command
-. libpcre2-32.pc       )
-. libpcre2-posix.pc    )
-. libtool              script that builds shared and/or static libraries
-
-Versions of config.h and pcre2.h are distributed in the src directory of PCRE2
-tarballs under the names config.h.generic and pcre2.h.generic. These are
-provided for those who have to build PCRE2 without using "configure" or CMake.
-If you use "configure" or CMake, the .generic versions are not used.
-
-The "configure" script also creates config.status, which is an executable
-script that can be run to recreate the configuration, and config.log, which
-contains compiler output from tests that "configure" runs.
-
-Once "configure" has run, you can run "make". This builds whichever of the
-libraries libpcre2-8, libpcre2-16 and libpcre2-32 are configured, and a test
-program called pcre2test. If you enabled JIT support with --enable-jit, another
-test program called pcre2_jit_test is built as well. If the 8-bit library is
-built, libpcre2-posix and the pcre2grep command are also built. Running
-"make" with the -j option may speed up compilation on multiprocessor systems.
-
-The command "make check" runs all the appropriate tests. Details of the PCRE2
-tests are given below in a separate section of this document. The -j option of
-"make" can also be used when running the tests.
-
-You can use "make install" to install PCRE2 into live directories on your
-system. The following are installed (file names are all relative to the
-<prefix> that is set when "configure" is run):
-
-  Commands (bin):
-    pcre2test
-    pcre2grep (if 8-bit support is enabled)
-    pcre2-config
-
-  Libraries (lib):
-    libpcre2-8      (if 8-bit support is enabled)
-    libpcre2-16     (if 16-bit support is enabled)
-    libpcre2-32     (if 32-bit support is enabled)
-    libpcre2-posix  (if 8-bit support is enabled)
-
-  Configuration information (lib/pkgconfig):
-    libpcre2-8.pc
-    libpcre2-16.pc
-    libpcre2-32.pc
-    libpcre2-posix.pc
-
-  Header files (include):
-    pcre2.h
-    pcre2posix.h
-
-  Man pages (share/man/man{1,3}):
-    pcre2grep.1
-    pcre2test.1
-    pcre2-config.1
-    pcre2.3
-    pcre2*.3 (lots more pages, all starting "pcre2")
-
-  HTML documentation (share/doc/pcre2/html):
-    index.html
-    *.html (lots more pages, hyperlinked from index.html)
-
-  Text file documentation (share/doc/pcre2):
-    AUTHORS
-    COPYING
-    ChangeLog
-    LICENCE
-    NEWS
-    README
-    pcre2.txt         (a concatenation of the man(3) pages)
-    pcre2test.txt     the pcre2test man page
-    pcre2grep.txt     the pcre2grep man page
-    pcre2-config.txt  the pcre2-config man page
-
-If you want to remove PCRE2 from your system, you can run "make uninstall".
-This removes all the files that "make install" installed. However, it does not
-remove any directories, because these are often shared with other programs.
-
-
-Retrieving configuration information
-------------------------------------
-
-Running "make install" installs the command pcre2-config, which can be used to
-recall information about the PCRE2 configuration and installation. For example:
-
-  pcre2-config --version
-
-prints the version number, and
-
-  pcre2-config --libs8
-
-outputs information about where the 8-bit library is installed. This command
-can be included in makefiles for programs that use PCRE2, saving the programmer
-from having to remember too many details. Run pcre2-config with no arguments to
-obtain a list of possible arguments.
-
-The pkg-config command is another system for saving and retrieving information
-about installed libraries. Instead of separate commands for each library, a
-single command is used. For example:
-
-  pkg-config --libs libpcre2-16
-
-The data is held in *.pc files that are installed in a directory called
-<prefix>/lib/pkgconfig.
-
-
-Shared libraries
-----------------
-
-The default distribution builds PCRE2 as shared libraries and static libraries,
-as long as the operating system supports shared libraries. Shared library
-support relies on the "libtool" script which is built as part of the
-"configure" process.
-
-The libtool script is used to compile and link both shared and static
-libraries. They are placed in a subdirectory called .libs when they are newly
-built. The programs pcre2test and pcre2grep are built to use these uninstalled
-libraries (by means of wrapper scripts in the case of shared libraries). When
-you use "make install" to install shared libraries, pcre2grep and pcre2test are
-automatically re-built to use the newly installed shared libraries before being
-installed themselves. However, the versions left in the build directory still
-use the uninstalled libraries.
-
-To build PCRE2 using static libraries only you must use --disable-shared when
-configuring it. For example:
-
-./configure --prefix=/usr/gnu --disable-shared
-
-Then run "make" in the usual way. Similarly, you can use --disable-static to
-build only shared libraries.
-
-
-Cross-compiling using autotools
--------------------------------
-
-You can specify CC and CFLAGS in the normal way to the "configure" command, in
-order to cross-compile PCRE2 for some other host. However, you should NOT
-specify --enable-rebuild-chartables, because if you do, the pcre2_dftables.c
-source file is compiled and run on the local host, in order to generate the
-inbuilt character tables (the pcre2_chartables.c file). This will probably not
-work, because pcre2_dftables.c needs to be compiled with the local compiler,
-not the cross compiler.
-
-When --enable-rebuild-chartables is not specified, pcre2_chartables.c is
-created by making a copy of pcre2_chartables.c.dist, which is a default set of
-tables that assumes ASCII code. Cross-compiling with the default tables should
-not be a problem.
-
-If you need to modify the character tables when cross-compiling, you should
-move pcre2_chartables.c.dist out of the way, then compile pcre2_dftables.c by
-hand and run it on the local host to make a new version of
-pcre2_chartables.c.dist. See the pcre2build section "Creating character tables
-at build time" for more details.
-
-
-Making new tarballs
--------------------
-
-The command "make dist" creates three PCRE2 tarballs, in tar.gz, tar.bz2, and
-zip formats. The command "make distcheck" does the same, but then does a trial
-build of the new distribution to ensure that it works.
-
-If you have modified any of the man page sources in the doc directory, you
-should first run the PrepareRelease script before making a distribution. This
-script creates the .txt and HTML forms of the documentation from the man pages.
-
-
-Testing PCRE2
--------------
-
-To test the basic PCRE2 library on a Unix-like system, run the RunTest script.
-There is another script called RunGrepTest that tests the pcre2grep command.
-When JIT support is enabled, a third test program called pcre2_jit_test is
-built. Both the scripts and all the program tests are run if you obey "make
-check". For other environments, see the instructions in NON-AUTOTOOLS-BUILD.
-
-The RunTest script runs the pcre2test test program (which is documented in its
-own man page) on each of the relevant testinput files in the testdata
-directory, and compares the output with the contents of the corresponding
-testoutput files. RunTest uses a file called testtry to hold the main output
-from pcre2test. Other files whose names begin with "test" are used as working
-files in some tests.
-
-Some tests are relevant only when certain build-time options were selected. For
-example, the tests for UTF-8/16/32 features are run only when Unicode support
-is available. RunTest outputs a comment when it skips a test.
-
-Many (but not all) of the tests that are not skipped are run twice if JIT
-support is available. On the second run, JIT compilation is forced. This
-testing can be suppressed by putting "nojit" on the RunTest command line.
-
-The entire set of tests is run once for each of the 8-bit, 16-bit and 32-bit
-libraries that are enabled. If you want to run just one set of tests, call
-RunTest with either the -8, -16 or -32 option.
-
-If valgrind is installed, you can run the tests under it by putting "valgrind"
-on the RunTest command line. To run pcre2test on just one or more specific test
-files, give their numbers as arguments to RunTest, for example:
-
-  RunTest 2 7 11
-
-You can also specify ranges of tests such as 3-6 or 3- (meaning 3 to the
-end), or a number preceded by ~ to exclude a test. For example:
-
-  Runtest 3-15 ~10
-
-This runs tests 3 to 15, excluding test 10, and just ~13 runs all the tests
-except test 13. Whatever order the arguments are in, the tests are always run
-in numerical order.
-
-You can also call RunTest with the single argument "list" to cause it to output
-a list of tests.
-
-The test sequence starts with "test 0", which is a special test that has no
-input file, and whose output is not checked. This is because it will be
-different on different hardware and with different configurations. The test
-exists in order to exercise some of pcre2test's code that would not otherwise
-be run.
-
-Tests 1 and 2 can always be run, as they expect only plain text strings (not
-UTF) and make no use of Unicode properties. The first test file can be fed
-directly into the perltest.sh script to check that Perl gives the same results.
-The only difference you should see is in the first few lines, where the Perl
-version is given instead of the PCRE2 version. The second set of tests check
-auxiliary functions, error detection, and run-time flags that are specific to
-PCRE2. It also uses the debugging flags to check some of the internals of
-pcre2_compile().
-
-If you build PCRE2 with a locale setting that is not the standard C locale, the
-character tables may be different (see next paragraph). In some cases, this may
-cause failures in the second set of tests. For example, in a locale where the
-isprint() function yields TRUE for characters in the range 128-255, the use of
-[:isascii:] inside a character class defines a different set of characters, and
-this shows up in this test as a difference in the compiled code, which is being
-listed for checking. For example, where the comparison test output contains
-[\x00-\x7f] the test might contain [\x00-\xff], and similarly in some other
-cases. This is not a bug in PCRE2.
-
-Test 3 checks pcre2_maketables(), the facility for building a set of character
-tables for a specific locale and using them instead of the default tables. The
-script uses the "locale" command to check for the availability of the "fr_FR",
-"french", or "fr" locale, and uses the first one that it finds. If the "locale"
-command fails, or if its output doesn't include "fr_FR", "french", or "fr" in
-the list of available locales, the third test cannot be run, and a comment is
-output to say why. If running this test produces an error like this:
-
-  ** Failed to set locale "fr_FR"
-
-it means that the given locale is not available on your system, despite being
-listed by "locale". This does not mean that PCRE2 is broken. There are three
-alternative output files for the third test, because three different versions
-of the French locale have been encountered. The test passes if its output
-matches any one of them.
-
-Tests 4 and 5 check UTF and Unicode property support, test 4 being compatible
-with the perltest.sh script, and test 5 checking PCRE2-specific things.
-
-Tests 6 and 7 check the pcre2_dfa_match() alternative matching function, in
-non-UTF mode and UTF-mode with Unicode property support, respectively.
-
-Test 8 checks some internal offsets and code size features, but it is run only
-when Unicode support is enabled. The output is different in 8-bit, 16-bit, and
-32-bit modes and for different link sizes, so there are different output files
-for each mode and link size.
-
-Tests 9 and 10 are run only in 8-bit mode, and tests 11 and 12 are run only in
-16-bit and 32-bit modes. These are tests that generate different output in
-8-bit mode. Each pair are for general cases and Unicode support, respectively.
-
-Test 13 checks the handling of non-UTF characters greater than 255 by
-pcre2_dfa_match() in 16-bit and 32-bit modes.
-
-Test 14 contains some special UTF and UCP tests that give different output for
-different code unit widths.
-
-Test 15 contains a number of tests that must not be run with JIT. They check,
-among other non-JIT things, the match-limiting features of the intepretive
-matcher.
-
-Test 16 is run only when JIT support is not available. It checks that an
-attempt to use JIT has the expected behaviour.
-
-Test 17 is run only when JIT support is available. It checks JIT complete and
-partial modes, match-limiting under JIT, and other JIT-specific features.
-
-Tests 18 and 19 are run only in 8-bit mode. They check the POSIX interface to
-the 8-bit library, without and with Unicode support, respectively.
-
-Test 20 checks the serialization functions by writing a set of compiled
-patterns to a file, and then reloading and checking them.
-
-Tests 21 and 22 test \C support when the use of \C is not locked out, without
-and with UTF support, respectively. Test 23 tests \C when it is locked out.
-
-Tests 24 and 25 test the experimental pattern conversion functions, without and
-with UTF support, respectively.
-
-
-Character tables
-----------------
-
-For speed, PCRE2 uses four tables for manipulating and identifying characters
-whose code point values are less than 256. By default, a set of tables that is
-built into the library is used. The pcre2_maketables() function can be called
-by an application to create a new set of tables in the current locale. This are
-passed to PCRE2 by calling pcre2_set_character_tables() to put a pointer into a
-compile context.
-
-The source file called pcre2_chartables.c contains the default set of tables.
-By default, this is created as a copy of pcre2_chartables.c.dist, which
-contains tables for ASCII coding. However, if --enable-rebuild-chartables is
-specified for ./configure, a new version of pcre2_chartables.c is built by the
-program pcre2_dftables (compiled from pcre2_dftables.c), which uses the ANSI C
-character handling functions such as isalnum(), isalpha(), isupper(),
-islower(), etc. to build the table sources. This means that the default C
-locale that is set for your system will control the contents of these default
-tables. You can change the default tables by editing pcre2_chartables.c and
-then re-building PCRE2. If you do this, you should take care to ensure that the
-file does not get automatically re-generated. The best way to do this is to
-move pcre2_chartables.c.dist out of the way and replace it with your customized
-tables.
-
-When the pcre2_dftables program is run as a result of specifying
---enable-rebuild-chartables, it uses the default C locale that is set on your
-system. It does not pay attention to the LC_xxx environment variables. In other
-words, it uses the system's default locale rather than whatever the compiling
-user happens to have set. If you really do want to build a source set of
-character tables in a locale that is specified by the LC_xxx variables, you can
-run the pcre2_dftables program by hand with the -L option. For example:
-
-  ./pcre2_dftables -L pcre2_chartables.c.special
-
-The second argument names the file where the source code for the tables is
-written. The first two 256-byte tables provide lower casing and case flipping
-functions, respectively. The next table consists of a number of 32-byte bit
-maps which identify certain character classes such as digits, "word"
-characters, white space, etc. These are used when building 32-byte bit maps
-that represent character classes for code points less than 256. The final
-256-byte table has bits indicating various character types, as follows:
-
-    1   white space character
-    2   letter
-    4   lower case letter
-    8   decimal digit
-   16   alphanumeric or '_'
-
-You can also specify -b (with or without -L) when running pcre2_dftables. This
-causes the tables to be written in binary instead of as source code. A set of
-binary tables can be loaded into memory by an application and passed to
-pcre2_compile() in the same way as tables created dynamically by calling
-pcre2_maketables(). The tables are just a string of bytes, independent of
-hardware characteristics such as endianness. This means they can be bundled
-with an application that runs in different environments, to ensure consistent
-behaviour.
-

-###############################################################################
-# Run the PCRE2 tests using the pcre2test program. The appropriate tests are
-# selected, depending on which build-time options were used.
-#
-# When JIT support is available, all appropriate tests are run with and without
-# JIT, unless "-nojit" is given on the command line. There are also two tests
-# for JIT-specific features, one to be run when JIT support is available
-# (unless "-nojit" is specified), and one when it is not.
-#
-# Whichever of the 8-, 16- and 32-bit libraries exist are tested. It is also
-# possible to select which to test by giving "-8", "-16" or "-32" on the
-# command line.
-#
-# As well as "-nojit", "-8", "-16", and "-32", arguments for this script are
-# individual test numbers, ranges of tests such as 3-6 or 3- (meaning 3 to the
-# end), or a number preceded by ~ to exclude a test. For example, "3-15 ~10"
-# runs tests 3 to 15, excluding test 10, and just "~10" runs all the tests
-# except test 10. Whatever order the arguments are in, the tests are always run
-# in numerical order.
-#
-# Inappropriate tests are automatically skipped (with a comment to say so). For
-# example, if JIT support is not compiled, test 16 is skipped, whereas if JIT
-# support is compiled, test 15 is skipped.
-#
-# Other arguments can be one of the words "-valgrind", "-valgrind-log", or
-# "-sim" followed by an argument to run cross-compiled executables under a
-# simulator, for example:
-#
-# RunTest 3 -sim "qemu-arm -s 8388608"
-#
-# For backwards compatibility, -nojit, -valgrind, -valgrind-log, and -sim may
-# be given without the leading "-" character.
-#
-# When PCRE2 is compiled by clang with -fsanitize arguments, some tests need
-# very much more stack than normal. In environments where the stack can be
-# set at runtime, -bigstack sets a gigantic stack.
-#
-# There are two special cases where only one argument is allowed:
-#
-# If the first and only argument is "ebcdic", the script runs the special
-# EBCDIC test that can be useful for checking certain EBCDIC features, even
-# when run in an ASCII environment. PCRE2 must be built with EBCDIC support for
-# this test to be run.
-#
-# If the script is obeyed as "RunTest list", a list of available tests is
-# output, but none of them are run.

-@rem MS Windows batch file to run pcre2test on testfiles with the correct
-@rem options. This file must use CRLF linebreaks to function properly,
-@rem and requires both pcre2test and pcre2grep.
-@rem
-@rem ------------------------ HISTORY ----------------------------------
-@rem This file was originally contributed to PCRE1 by Ralf Junker, and touched
-@rem up by Daniel Richard G. Tests 10-12 added by Philip H.
-@rem Philip H also changed test 3 to use "wintest" files.
-@rem
-@rem Updated by Tom Fortmann to support explicit test numbers on the command
-@rem line. Added argument validation and added error reporting.
-@rem
-@rem Sheri Pierce added logic to skip feature dependent tests
-@rem tests 4 5 7 10 12 14 19 and 22 require Unicode support
-@rem 8 requires Unicode and link size 2
-@rem 16 requires absence of jit support
-@rem 17 requires presence of jit support
-@rem Sheri P also added override tests for study and jit testing
-@rem Zoltan Herczeg added libpcre16 support
-@rem Zoltan Herczeg added libpcre32 support
-@rem -------------------------------------------------------------------
-@rem
-@rem The file was converted for PCRE2 by PH, February 2015.
-@rem Updated for new test 14 (moving others up a number), August 2015.
-@rem Tidied and updated for new tests 21, 22, 23 by PH, October 2015.
-@rem PH added missing "set type" for test 22, April 2016.
-@rem PH added copy command for new testbtables file, November 2020

-#    it also sets the <UPPERCASED_NAME>_FOUND variable.
-#    The package is found if all variables listed are TRUE.
-#    Example:

-#
-#    LibXml2 is considered to be found, if both LIBXML2_LIBRARIES and

-#    If it is not found and REQUIRED was used, it fails with FATAL_ERROR, 
-#    independent whether QUIET was used or not.
-#    If it is found, the location is reported using the VAR1 argument, so 
-#    here a message "Found LibXml2: /usr/lib/libxml2.so" will be printed out.
-#    If the second argument is DEFAULT_MSG, the message in the failure case will

-
-In environments that support the GNU autotools, config.h.in is converted into
-config.h by the "configure" script. In environments that use CMake,
-config-cmake.in is converted into config.h. If you are going to build PCRE2 "by
-hand" without using "configure" or CMake, you should copy the distributed
-config.h.generic to config.h, and edit the macro definitions to be the way you
-need them. You must then add -DHAVE_CONFIG_H to all of your compile commands,
-so that config.h is included at the start of every source.
-
-Alternatively, you can avoid editing by using -D on the compiler command line
-to set the macro values. In this case, you do not have to set -DHAVE_CONFIG_H,
-but if you do, default values will be taken from config.h for non-boolean
-macros that are not defined on the command line.
-
-Boolean macros such as HAVE_STDLIB_H and SUPPORT_PCRE2_8 should either be
-defined (conventionally to 1) for TRUE, and not defined at all for FALSE. All
-such macros are listed as a commented #undef in config.h.generic. Macros such
-as MATCH_LIMIT, whose actual value is relevant, have defaults defined, but are
-surrounded by #ifndef/#endif lines so that the value can be overridden by -D.
-
-PCRE2 uses memmove() if HAVE_MEMMOVE is defined; otherwise it uses bcopy() if

-Building PCRE2 without using autotools
---------------------------------------
-
-This document contains the following sections:
-
-  General
-  Generic instructions for the PCRE2 C library
-  Stack size in Windows environments
-  Linking programs in Windows environments
-  Calling conventions in Windows environments
-  Comments about Win32 builds
-  Building PCRE2 on Windows with CMake
-  Building PCRE2 on Windows with Visual Studio
-  Testing with RunTest.bat
-  Building PCRE2 on native z/OS and z/VM
-
-
-GENERAL
-
-The basic PCRE2 library consists entirely of code written in Standard C, and so
-should compile successfully on any system that has a Standard C compiler and
-library.
-
-The PCRE2 distribution includes a "configure" file for use by the
-configure/make (autotools) build system, as found in many Unix-like
-environments. The README file contains information about the options for
-"configure".
-
-There is also support for CMake, which some users prefer, especially in Windows
-environments, though it can also be run in Unix-like environments. See the
-section entitled "Building PCRE2 on Windows with CMake" below.
-
-Versions of src/config.h and src/pcre2.h are distributed in the PCRE2 tarballs
-under the names src/config.h.generic and src/pcre2.h.generic. These are
-provided for those who build PCRE2 without using "configure" or CMake. If you
-use "configure" or CMake, the .generic versions are not used.
-
-
-GENERIC INSTRUCTIONS FOR THE PCRE2 C LIBRARY
-
-The following are generic instructions for building the PCRE2 C library "by
-hand". If you are going to use CMake, this section does not apply to you; you
-can skip ahead to the CMake section. Note that the settings concerned with
-8-bit, 16-bit, and 32-bit code units relate to the type of data string that
-PCRE2 processes. They are NOT referring to the underlying operating system bit
-width. You do not have to do anything special to compile in a 64-bit
-environment, for example.
-
- (1) Copy or rename the file src/config.h.generic as src/config.h, and edit the
-     macro settings that it contains to whatever is appropriate for your
-     environment. In particular, you can alter the definition of the NEWLINE
-     macro to specify what character(s) you want to be interpreted as line
-     terminators by default.
-
-     When you subsequently compile any of the PCRE2 modules, you must specify
-     -DHAVE_CONFIG_H to your compiler so that src/config.h is included in the
-     sources.
-
-     An alternative approach is not to edit src/config.h, but to use -D on the
-     compiler command line to make any changes that you need to the
-     configuration options. In this case -DHAVE_CONFIG_H must not be set.
-
-     NOTE: There have been occasions when the way in which certain parameters
-     in src/config.h are used has changed between releases. (In the
-     configure/make world, this is handled automatically.) When upgrading to a
-     new release, you are strongly advised to review src/config.h.generic
-     before re-using what you had previously.
-
-     Note also that the src/config.h.generic file is created from a config.h
-     that was generated by Autotools, which automatically includes settings of
-     a number of macros that are not actually used by PCRE2 (for example,
-     HAVE_MEMORY_H).
-
- (2) Copy or rename the file src/pcre2.h.generic as src/pcre2.h.
-
- (3) EITHER:
-       Copy or rename file src/pcre2_chartables.c.dist as
-       src/pcre2_chartables.c.
-
-     OR:
-       Compile src/pcre2_dftables.c as a stand-alone program (using
-       -DHAVE_CONFIG_H if you have set up src/config.h), and then run it with
-       the single argument "src/pcre2_chartables.c". This generates a set of
-       standard character tables and writes them to that file. The tables are
-       generated using the default C locale for your system. If you want to use
-       a locale that is specified by LC_xxx environment variables, add the -L
-       option to the pcre2_dftables command. You must use this method if you
-       are building on a system that uses EBCDIC code.
-
-     The tables in src/pcre2_chartables.c are defaults. The caller of PCRE2 can
-     specify alternative tables at run time.
-
- (4) For a library that supports 8-bit code units in the character strings that
-     it processes, compile the following source files from the src directory,
-     setting -DPCRE2_CODE_UNIT_WIDTH=8 as a compiler option. Also set
-     -DHAVE_CONFIG_H if you have set up src/config.h with your configuration,
-     or else use other -D settings to change the configuration as required.
-
-       pcre2_auto_possess.c
-       pcre2_chartables.c
-       pcre2_compile.c
-       pcre2_config.c
-       pcre2_context.c
-       pcre2_convert.c
-       pcre2_dfa_match.c
-       pcre2_error.c
-       pcre2_extuni.c
-       pcre2_find_bracket.c
-       pcre2_jit_compile.c
-       pcre2_maketables.c
-       pcre2_match.c
-       pcre2_match_data.c
-       pcre2_newline.c
-       pcre2_ord2utf.c
-       pcre2_pattern_info.c
-       pcre2_script_run.c
-       pcre2_serialize.c
-       pcre2_string_utils.c
-       pcre2_study.c
-       pcre2_substitute.c
-       pcre2_substring.c
-       pcre2_tables.c
-       pcre2_ucd.c
-       pcre2_valid_utf.c
-       pcre2_xclass.c
-
-     Make sure that you include -I. in the compiler command (or equivalent for
-     an unusual compiler) so that all included PCRE2 header files are first
-     sought in the src directory under the current directory. Otherwise you run
-     the risk of picking up a previously-installed file from somewhere else.
-
-     Note that you must compile pcre2_jit_compile.c, even if you have not
-     defined SUPPORT_JIT in src/config.h, because when JIT support is not
-     configured, dummy functions are compiled. When JIT support IS configured,
-     pcre2_jit_compile.c #includes other files from the sljit subdirectory,
-     all of whose names begin with "sljit". It also #includes
-     src/pcre2_jit_match.c and src/pcre2_jit_misc.c, so you should not compile
-     these yourself.
-
-     Note also that the pcre2_fuzzsupport.c file contains special code that is
-     useful to those who want to run fuzzing tests on the PCRE2 library. Unless
-     you are doing that, you can ignore it.
-
- (5) Now link all the compiled code into an object library in whichever form
-     your system keeps such libraries. This is the basic PCRE2 C 8-bit library.
-     If your system has static and shared libraries, you may have to do this
-     once for each type.
-
- (6) If you want to build a library that supports 16-bit or 32-bit code units,
-     (as well as, or instead of the 8-bit library) just supply 16 or 32 as the
-     value of -DPCRE2_CODE_UNIT_WIDTH when you are compiling.
-
- (7) If you want to build the POSIX wrapper functions (which apply only to the
-     8-bit library), ensure that you have the src/pcre2posix.h file and then
-     compile src/pcre2posix.c. Link the result (on its own) as the pcre2posix
-     library.
-
- (8) The pcre2test program can be linked with any combination of the 8-bit,
-     16-bit and 32-bit libraries (depending on what you selected in
-     src/config.h). Compile src/pcre2test.c; don't forget -DHAVE_CONFIG_H if
-     necessary, but do NOT define PCRE2_CODE_UNIT_WIDTH. Then link with the
-     appropriate library/ies. If you compiled an 8-bit library, pcre2test also
-     needs the pcre2posix wrapper library.
-
- (9) Run pcre2test on the testinput files in the testdata directory, and check
-     that the output matches the corresponding testoutput files. There are
-     comments about what each test does in the section entitled "Testing PCRE2"
-     in the README file. If you compiled more than one of the 8-bit, 16-bit and
-     32-bit libraries, you need to run pcre2test with the -16 option to do
-     16-bit tests and with the -32 option to do 32-bit tests.
-
-     Some tests are relevant only when certain build-time options are selected.
-     For example, test 4 is for Unicode support, and will not run if you have
-     built PCRE2 without it. See the comments at the start of each testinput
-     file. If you have a suitable Unix-like shell, the RunTest script will run
-     the appropriate tests for you. The command "RunTest list" will output a
-     list of all the tests.
-
-     Note that the supplied files are in Unix format, with just LF characters
-     as line terminators. You may need to edit them to change this if your
-     system uses a different convention.
-
-(10) If you have built PCRE2 with SUPPORT_JIT, the JIT features can be tested
-     by running pcre2test with the -jit option. This is done automatically by
-     the RunTest script. You might also like to build and run the freestanding
-     JIT test program, src/pcre2_jit_test.c.
-
-(11) If you want to use the pcre2grep command, compile and link
-     src/pcre2grep.c; it uses only the basic 8-bit PCRE2 library (it does not
-     need the pcre2posix library). If you have built the PCRE2 library with JIT
-     support by defining SUPPORT_JIT in src/config.h, you can also define
-     SUPPORT_PCRE2GREP_JIT, which causes pcre2grep to make use of JIT (unless
-     it is run with --no-jit). If you define SUPPORT_PCRE2GREP_JIT without
-     defining SUPPORT_JIT, pcre2grep does not try to make use of JIT.
-
-
-STACK SIZE IN WINDOWS ENVIRONMENTS
-
-Prior to release 10.30 the default system stack size of 1MiB in some Windows
-environments caused issues with some tests. This should no longer be the case
-for 10.30 and later releases.
-
-
-LINKING PROGRAMS IN WINDOWS ENVIRONMENTS
-
-If you want to statically link a program against a PCRE2 library in the form of
-a non-dll .a file, you must define PCRE2_STATIC before including src/pcre2.h.
-
-
-CALLING CONVENTIONS IN WINDOWS ENVIRONMENTS
-
-It is possible to compile programs to use different calling conventions using
-MSVC. Search the web for "calling conventions" for more information. To make it
-easier to change the calling convention for the exported functions in the
-PCRE2 library, the macro PCRE2_CALL_CONVENTION is present in all the external
-definitions. It can be set externally when compiling (e.g. in CFLAGS). If it is
-not set, it defaults to empty; the default calling convention is then used
-(which is what is wanted most of the time).
-
-
-COMMENTS ABOUT WIN32 BUILDS (see also "BUILDING PCRE2 ON WINDOWS WITH CMAKE")
-
-There are two ways of building PCRE2 using the "configure, make, make install"
-paradigm on Windows systems: using MinGW or using Cygwin. These are not at all
-the same thing; they are completely different from each other. There is also
-support for building using CMake, which some users find a more straightforward
-way of building PCRE2 under Windows.
-
-The MinGW home page (http://www.mingw.org/) says this:
-
-  MinGW: A collection of freely available and freely distributable Windows
-  specific header files and import libraries combined with GNU toolsets that
-  allow one to produce native Windows programs that do not rely on any
-  3rd-party C runtime DLLs.
-
-The Cygwin home page (http://www.cygwin.com/) says this:
-
-  Cygwin is a Linux-like environment for Windows. It consists of two parts:
-
-  . A DLL (cygwin1.dll) which acts as a Linux API emulation layer providing
-    substantial Linux API functionality
-
-  . A collection of tools which provide Linux look and feel.
-
-On both MinGW and Cygwin, PCRE2 should build correctly using:
-
-  ./configure && make && make install
-
-This should create two libraries called libpcre2-8 and libpcre2-posix. These
-are independent libraries: when you link with libpcre2-posix you must also link
-with libpcre2-8, which contains the basic functions.
-
-Using Cygwin's compiler generates libraries and executables that depend on
-cygwin1.dll. If a library that is generated this way is distributed,
-cygwin1.dll has to be distributed as well. Since cygwin1.dll is under the GPL
-licence, this forces not only PCRE2 to be under the GPL, but also the entire
-application. A distributor who wants to keep their own code proprietary must
-purchase an appropriate Cygwin licence.
-
-MinGW has no such restrictions. The MinGW compiler generates a library or
-executable that can run standalone on Windows without any third party dll or
-licensing issues.
-
-But there is more complication:
-
-If a Cygwin user uses the -mno-cygwin Cygwin gcc flag, what that really does is
-to tell Cygwin's gcc to use the MinGW gcc. Cygwin's gcc is only acting as a
-front end to MinGW's gcc (if you install Cygwin's gcc, you get both Cygwin's
-gcc and MinGW's gcc). So, a user can:
-
-. Build native binaries by using MinGW or by getting Cygwin and using
-  -mno-cygwin.
-
-. Build binaries that depend on cygwin1.dll by using Cygwin with the normal
-  compiler flags.
-
-The test files that are supplied with PCRE2 are in UNIX format, with LF
-characters as line terminators. Unless your PCRE2 library uses a default
-newline option that includes LF as a valid newline, it may be necessary to
-change the line terminators in the test files to get some of the tests to work.
-
-
-BUILDING PCRE2 ON WINDOWS WITH CMAKE
-
-CMake is an alternative configuration facility that can be used instead of
-"configure". CMake creates project files (make files, solution files, etc.)
-tailored to numerous development environments, including Visual Studio,
-Borland, Msys, MinGW, NMake, and Unix. If possible, use short paths with no
-spaces in the names for your CMake installation and your PCRE2 source and build
-directories.
-
-The following instructions were contributed by a PCRE1 user, but they should
-also work for PCRE2. If they are not followed exactly, errors may occur. In the
-event that errors do occur, it is recommended that you delete the CMake cache
-before attempting to repeat the CMake build process. In the CMake GUI, the
-cache can be deleted by selecting "File > Delete Cache".
-
-1.  Install the latest CMake version available from http://www.cmake.org/, and
-    ensure that cmake\bin is on your path.
-
-2.  Unzip (retaining folder structure) the PCRE2 source tree into a source
-    directory such as C:\pcre2. You should ensure your local date and time
-    is not earlier than the file dates in your source dir if the release is
-    very new.
-
-3.  Create a new, empty build directory, preferably a subdirectory of the
-    source dir. For example, C:\pcre2\pcre2-xx\build.
-
-4.  Run cmake-gui from the Shell envirornment of your build tool, for example,
-    Msys for Msys/MinGW or Visual Studio Command Prompt for VC/VC++. Do not try
-    to start Cmake from the Windows Start menu, as this can lead to errors.
-
-5.  Enter C:\pcre2\pcre2-xx and C:\pcre2\pcre2-xx\build for the source and
-    build directories, respectively.
-
-6.  Hit the "Configure" button.
-
-7.  Select the particular IDE / build tool that you are using (Visual
-    Studio, MSYS makefiles, MinGW makefiles, etc.)
-
-8.  The GUI will then list several configuration options. This is where
-    you can disable Unicode support or select other PCRE2 optional features.
-
-9.  Hit "Configure" again. The adjacent "Generate" button should now be
-    active.
-
-10. Hit "Generate".
-
-11. The build directory should now contain a usable build system, be it a
-    solution file for Visual Studio, makefiles for MinGW, etc. Exit from
-    cmake-gui and use the generated build system with your compiler or IDE.
-    E.g., for MinGW you can run "make", or for Visual Studio, open the PCRE2
-    solution, select the desired configuration (Debug, or Release, etc.) and
-    build the ALL_BUILD project.
-
-12. If during configuration with cmake-gui you've elected to build the test
-    programs, you can execute them by building the test project. E.g., for
-    MinGW: "make test"; for Visual Studio build the RUN_TESTS project. The
-    most recent build configuration is targeted by the tests. A summary of
-    test results is presented. Complete test output is subsequently
-    available for review in Testing\Temporary under your build dir.
-
-
-BUILDING PCRE2 ON WINDOWS WITH VISUAL STUDIO
-
-The code currently cannot be compiled without a stdint.h header, which is
-available only in relatively recent versions of Visual Studio. However, this
-portable and permissively-licensed implementation of the header worked without
-issue:
-
-  http://www.azillionmonkeys.com/qed/pstdint.h
-
-Just rename it and drop it into the top level of the build tree.
-
-
-TESTING WITH RUNTEST.BAT
-
-If configured with CMake, building the test project ("make test" or building
-ALL_TESTS in Visual Studio) creates (and runs) pcre2_test.bat (and depending
-on your configuration options, possibly other test programs) in the build
-directory. The pcre2_test.bat script runs RunTest.bat with correct source and
-exe paths.
-
-For manual testing with RunTest.bat, provided the build dir is a subdirectory
-of the source directory: Open command shell window. Chdir to the location
-of your pcre2test.exe and pcre2grep.exe programs. Call RunTest.bat with
-"..\RunTest.Bat" or "..\..\RunTest.bat" as appropriate.
-
-To run only a particular test with RunTest.Bat provide a test number argument.
-
-Otherwise:
-
-1. Copy RunTest.bat into the directory where pcre2test.exe and pcre2grep.exe
-   have been created.
-
-2. Edit RunTest.bat to indentify the full or relative location of
-   the pcre2 source (wherein which the testdata folder resides), e.g.:
-
-   set srcdir=C:\pcre2\pcre2-10.00
-
-3. In a Windows command environment, chdir to the location of your bat and
-   exe programs.
-
-4. Run RunTest.bat. Test outputs will automatically be compared to expected
-   results, and discrepancies will be identified in the console output.
-
-To independently test the just-in-time compiler, run pcre2_jit_test.exe.
-
-
-BUILDING PCRE2 ON NATIVE Z/OS AND Z/VM
-
-z/OS and z/VM are operating systems for mainframe computers, produced by IBM.
-The character code used is EBCDIC, not ASCII or Unicode. In z/OS, UNIX APIs and
-applications can be supported through UNIX System Services, and in such an
-environment it should be possible to build PCRE2 in the same way as in other
-systems, with the EBCDIC related configuration settings, but it is not known if
-anybody has tried this.
-
-In native z/OS (without UNIX System Services) and in z/VM, special ports are
-required. For details, please see file 939 on this web site:
-
-  http://www.cbttape.org
-
-Everything in that location, source and executable, is in EBCDIC and native
-z/OS file formats. The port provides an API for LE languages such as COBOL and
-for the z/OS and z/VM versions of the Rexx languages.

-README file for PCRE2 (Perl-compatible regular expression library)
-------------------------------------------------------------------
-
-PCRE2 is a re-working of the original PCRE1 library to provide an entirely new
-API. Since its initial release in 2015, there has been further development of
-the code and it now differs from PCRE1 in more than just the API. There are new
-features, and the internals have been improved. The original PCRE1 library is
-now obsolete and should not be used in new projects. The latest release of
-PCRE2 is available in three alternative formats from:
-
-https://ftp.pcre.org/pub/pcre/pcre2-10.xx.tar.gz
-https://ftp.pcre.org/pub/pcre/pcre2-10.xx.tar.bz2
-https://ftp.pcre.org/pub/pcre/pcre2-10.xx.tar.zip
-
-There is a mailing list for discussion about the development of PCRE at
-pcre-dev@exim.org. You can access the archives and subscribe or manage your
-subscription here:
-
-   https://lists.exim.org/mailman/listinfo/pcre-dev
-
-Please read the NEWS file if you are upgrading from a previous release. The
-contents of this README file are:
-
-  The PCRE2 APIs
-  Documentation for PCRE2
-  Contributions by users of PCRE2
-  Building PCRE2 on non-Unix-like systems
-  Building PCRE2 without using autotools

-  Retrieving configuration information
-  Shared libraries
-  Cross-compiling using autotools
-  Making new tarballs
-  Testing PCRE2
-  Character tables
-  File manifest
-
-
-The PCRE2 APIs
---------------
-
-PCRE2 is written in C, and it has its own API. There are three sets of
-functions, one for the 8-bit library, which processes strings of bytes, one for
-the 16-bit library, which processes strings of 16-bit values, and one for the
-32-bit library, which processes strings of 32-bit values. Unlike PCRE1, there
-are no C++ wrappers.
-
-The distribution does contain a set of C wrapper functions for the 8-bit
-library that are based on the POSIX regular expression API (see the pcre2posix
-man page). These are built into a library called libpcre2-posix. Note that this
-just provides a POSIX calling interface to PCRE2; the regular expressions
-themselves still follow Perl syntax and semantics. The POSIX API is restricted,
-and does not give full access to all of PCRE2's facilities.
-
-The header file for the POSIX-style functions is called pcre2posix.h. The
-official POSIX name is regex.h, but I did not want to risk possible problems
-with existing files of that name by distributing it that way. To use PCRE2 with
-an existing program that uses the POSIX API, pcre2posix.h will have to be
-renamed or pointed at by a link (or the program modified, of course). See the
-pcre2posix documentation for more details.
-
-
-Documentation for PCRE2
------------------------
-
-If you install PCRE2 in the normal way on a Unix-like system, you will end up
-with a set of man pages whose names all start with "pcre2". The one that is
-just called "pcre2" lists all the others. In addition to these man pages, the
-PCRE2 documentation is supplied in two other forms:
-
-  1. There are files called doc/pcre2.txt, doc/pcre2grep.txt, and
-     doc/pcre2test.txt in the source distribution. The first of these is a
-     concatenation of the text forms of all the section 3 man pages except the
-     listing of pcre2demo.c and those that summarize individual functions. The
-     other two are the text forms of the section 1 man pages for the pcre2grep
-     and pcre2test commands. These text forms are provided for ease of scanning
-     with text editors or similar tools. They are installed in
-     <prefix>/share/doc/pcre2, where <prefix> is the installation prefix
-     (defaulting to /usr/local).
-
-  2. A set of files containing all the documentation in HTML form, hyperlinked
-     in various ways, and rooted in a file called index.html, is distributed in
-     doc/html and installed in <prefix>/share/doc/pcre2/html.
-
-
-Building PCRE2 on non-Unix-like systems
----------------------------------------
-
-For a non-Unix-like system, please read the file NON-AUTOTOOLS-BUILD, though if
-your system supports the use of "configure" and "make" you may be able to build
-PCRE2 using autotools in the same way as for many Unix-like systems.
-
-PCRE2 can also be configured using CMake, which can be run in various ways
-(command line, GUI, etc). This creates Makefiles, solution files, etc. The file
-NON-AUTOTOOLS-BUILD has information about CMake.
-
-PCRE2 has been compiled on many different operating systems. It should be
-straightforward to build PCRE2 on any system that has a Standard C compiler and
-library, because it uses only Standard C functions.
-
-
-Building PCRE2 without using autotools
---------------------------------------
-
-The use of autotools (in particular, libtool) is problematic in some
-environments, even some that are Unix or Unix-like. See the NON-AUTOTOOLS-BUILD
-file for ways of building PCRE2 without using autotools.
-
-
-Building PCRE2 using autotools
-------------------------------
-
-The following instructions assume the use of the widely used "configure; make;
-make install" (autotools) process.
-
-To build PCRE2 on system that supports autotools, first run the "configure"
-command from the PCRE2 distribution directory, with your current directory set
-to the directory where you want the files to be created. This command is a
-standard GNU "autoconf" configuration script, for which generic instructions
-are supplied in the file INSTALL.
-
-Most commonly, people build PCRE2 within its own distribution directory, and in
-this case, on many systems, just running "./configure" is sufficient. However,
-the usual methods of changing standard defaults are available. For example:
-
-CFLAGS='-O2 -Wall' ./configure --prefix=/opt/local
-
-This command specifies that the C compiler should be run with the flags '-O2
--Wall' instead of the default, and that "make install" should install PCRE2
-under /opt/local instead of the default /usr/local.
-
-If you want to build in a different directory, just run "configure" with that
-directory as current. For example, suppose you have unpacked the PCRE2 source
-into /source/pcre2/pcre2-xxx, but you want to build it in
-/build/pcre2/pcre2-xxx:
-
-cd /build/pcre2/pcre2-xxx
-/source/pcre2/pcre2-xxx/configure
-
-PCRE2 is written in C and is normally compiled as a C library. However, it is
-possible to build it as a C++ library, though the provided building apparatus
-does not have any features to support this.
-
-There are some optional features that can be included or omitted from the PCRE2
-library. They are also documented in the pcre2build man page.
-
-. By default, both shared and static libraries are built. You can change this
-  by adding one of these options to the "configure" command:
-
-  --disable-shared
-  --disable-static
-
-  (See also "Shared libraries on Unix-like systems" below.)
-
-. By default, only the 8-bit library is built. If you add --enable-pcre2-16 to
-  the "configure" command, the 16-bit library is also built. If you add
-  --enable-pcre2-32 to the "configure" command, the 32-bit library is also
-  built. If you want only the 16-bit or 32-bit library, use --disable-pcre2-8
-  to disable building the 8-bit library.
-
-. If you want to include support for just-in-time (JIT) compiling, which can
-  give large performance improvements on certain platforms, add --enable-jit to
-  the "configure" command. This support is available only for certain hardware
-  architectures. If you try to enable it on an unsupported architecture, there
-  will be a compile time error. If in doubt, use --enable-jit=auto, which
-  enables JIT only if the current hardware is supported.
-
-. If you are enabling JIT under SELinux environment you may also want to add
-  --enable-jit-sealloc, which enables the use of an executable memory allocator
-  that is compatible with SELinux. Warning: this allocator is experimental!
-  It does not support fork() operation and may crash when no disk space is
-  available. This option has no effect if JIT is disabled.
-
-. If you do not want to make use of the default support for UTF-8 Unicode
-  character strings in the 8-bit library, UTF-16 Unicode character strings in
-  the 16-bit library, or UTF-32 Unicode character strings in the 32-bit
-  library, you can add --disable-unicode to the "configure" command. This
-  reduces the size of the libraries. It is not possible to configure one
-  library with Unicode support, and another without, in the same configuration.
-  It is also not possible to use --enable-ebcdic (see below) with Unicode
-  support, so if this option is set, you must also use --disable-unicode.
-
-  When Unicode support is available, the use of a UTF encoding still has to be
-  enabled by setting the PCRE2_UTF option at run time or starting a pattern
-  with (*UTF). When PCRE2 is compiled with Unicode support, its input can only
-  either be ASCII or UTF-8/16/32, even when running on EBCDIC platforms.
-
-  As well as supporting UTF strings, Unicode support includes support for the
-  \P, \p, and \X sequences that recognize Unicode character properties.
-  However, only the basic two-letter properties such as Lu are supported.
-  Escape sequences such as \d and \w in patterns do not by default make use of
-  Unicode properties, but can be made to do so by setting the PCRE2_UCP option
-  or starting a pattern with (*UCP).
-
-. You can build PCRE2 to recognize either CR or LF or the sequence CRLF, or any
-  of the preceding, or any of the Unicode newline sequences, or the NUL (zero)
-  character as indicating the end of a line. Whatever you specify at build time
-  is the default; the caller of PCRE2 can change the selection at run time. The
-  default newline indicator is a single LF character (the Unix standard). You
-  can specify the default newline indicator by adding --enable-newline-is-cr,
-  --enable-newline-is-lf, --enable-newline-is-crlf,
-  --enable-newline-is-anycrlf, --enable-newline-is-any, or
-  --enable-newline-is-nul to the "configure" command, respectively.
-
-. By default, the sequence \R in a pattern matches any Unicode line ending
-  sequence. This is independent of the option specifying what PCRE2 considers
-  to be the end of a line (see above). However, the caller of PCRE2 can
-  restrict \R to match only CR, LF, or CRLF. You can make this the default by
-  adding --enable-bsr-anycrlf to the "configure" command (bsr = "backslash R").
-
-. In a pattern, the escape sequence \C matches a single code unit, even in a
-  UTF mode. This can be dangerous because it breaks up multi-code-unit
-  characters. You can build PCRE2 with the use of \C permanently locked out by
-  adding --enable-never-backslash-C (note the upper case C) to the "configure"
-  command. When \C is allowed by the library, individual applications can lock
-  it out by calling pcre2_compile() with the PCRE2_NEVER_BACKSLASH_C option.
-
-. PCRE2 has a counter that limits the depth of nesting of parentheses in a
-  pattern. This limits the amount of system stack that a pattern uses when it
-  is compiled. The default is 250, but you can change it by setting, for
-  example,
-
-  --with-parens-nest-limit=500
-
-. PCRE2 has a counter that can be set to limit the amount of computing resource
-  it uses when matching a pattern. If the limit is exceeded during a match, the
-  match fails. The default is ten million. You can change the default by
-  setting, for example,
-
-  --with-match-limit=500000
-
-  on the "configure" command. This is just the default; individual calls to
-  pcre2_match() or pcre2_dfa_match() can supply their own value. There is more
-  discussion in the pcre2api man page (search for pcre2_set_match_limit).
-
-. There is a separate counter that limits the depth of nested backtracking
-  (pcre2_match()) or nested function calls (pcre2_dfa_match()) during a
-  matching process, which indirectly limits the amount of heap memory that is
-  used, and in the case of pcre2_dfa_match() the amount of stack as well. This
-  counter also has a default of ten million, which is essentially "unlimited".
-  You can change the default by setting, for example,
-
-  --with-match-limit-depth=5000
-
-  There is more discussion in the pcre2api man page (search for
-  pcre2_set_depth_limit).
-
-. You can also set an explicit limit on the amount of heap memory used by
-  the pcre2_match() and pcre2_dfa_match() interpreters:
-
-  --with-heap-limit=500
-
-  The units are kibibytes (units of 1024 bytes). This limit does not apply when
-  the JIT optimization (which has its own memory control features) is used.
-  There is more discussion on the pcre2api man page (search for
-  pcre2_set_heap_limit).
-
-. In the 8-bit library, the default maximum compiled pattern size is around
-  64 kibibytes. You can increase this by adding --with-link-size=3 to the
-  "configure" command. PCRE2 then uses three bytes instead of two for offsets
-  to different parts of the compiled pattern. In the 16-bit library,
-  --with-link-size=3 is the same as --with-link-size=4, which (in both
-  libraries) uses four-byte offsets. Increasing the internal link size reduces
-  performance in the 8-bit and 16-bit libraries. In the 32-bit library, the
-  link size setting is ignored, as 4-byte offsets are always used.
-
-. For speed, PCRE2 uses four tables for manipulating and identifying characters
-  whose code point values are less than 256. By default, it uses a set of
-  tables for ASCII encoding that is part of the distribution. If you specify
-
-  --enable-rebuild-chartables
-
-  a program called pcre2_dftables is compiled and run in the default C locale
-  when you obey "make". It builds a source file called pcre2_chartables.c. If
-  you do not specify this option, pcre2_chartables.c is created as a copy of
-  pcre2_chartables.c.dist. See "Character tables" below for further
-  information.
-
-. It is possible to compile PCRE2 for use on systems that use EBCDIC as their
-  character code (as opposed to ASCII/Unicode) by specifying
-
-  --enable-ebcdic --disable-unicode
-
-  This automatically implies --enable-rebuild-chartables (see above). However,
-  when PCRE2 is built this way, it always operates in EBCDIC. It cannot support
-  both EBCDIC and UTF-8/16/32. There is a second option, --enable-ebcdic-nl25,
-  which specifies that the code value for the EBCDIC NL character is 0x25
-  instead of the default 0x15.
-
-. If you specify --enable-debug, additional debugging code is included in the
-  build. This option is intended for use by the PCRE2 maintainers.
-
-. In environments where valgrind is installed, if you specify
-
-  --enable-valgrind
-
-  PCRE2 will use valgrind annotations to mark certain memory regions as
-  unaddressable. This allows it to detect invalid memory accesses, and is
-  mostly useful for debugging PCRE2 itself.
-
-. In environments where the gcc compiler is used and lcov is installed, if you
-  specify
-
-  --enable-coverage
-
-  the build process implements a code coverage report for the test suite. The
-  report is generated by running "make coverage". If ccache is installed on
-  your system, it must be disabled when building PCRE2 for coverage reporting.
-  You can do this by setting the environment variable CCACHE_DISABLE=1 before
-  running "make" to build PCRE2. There is more information about coverage
-  reporting in the "pcre2build" documentation.
-
-. When JIT support is enabled, pcre2grep automatically makes use of it, unless
-  you add --disable-pcre2grep-jit to the "configure" command.
-
-. There is support for calling external programs during matching in the
-  pcre2grep command, using PCRE2's callout facility with string arguments. This
-  support can be disabled by adding --disable-pcre2grep-callout to the
-  "configure" command. There are two kinds of callout: one that generates
-  output from inbuilt code, and another that calls an external program. The
-  latter has special support for Windows and VMS; otherwise it assumes the
-  existence of the fork() function. This facility can be disabled by adding
-  --disable-pcre2grep-callout-fork to the "configure" command.
-
-. The pcre2grep program currently supports only 8-bit data files, and so
-  requires the 8-bit PCRE2 library. It is possible to compile pcre2grep to use
-  libz and/or libbz2, in order to read .gz and .bz2 files (respectively), by
-  specifying one or both of
-
-  --enable-pcre2grep-libz
-  --enable-pcre2grep-libbz2
-
-  Of course, the relevant libraries must be installed on your system.
-
-. The default starting size (in bytes) of the internal buffer used by pcre2grep
-  can be set by, for example:
-
-  --with-pcre2grep-bufsize=51200
-
-  The value must be a plain integer. The default is 20480. The amount of memory
-  used by pcre2grep is actually three times this number, to allow for "before"
-  and "after" lines. If very long lines are encountered, the buffer is
-  automatically enlarged, up to a fixed maximum size.
-
-. The default maximum size of pcre2grep's internal buffer can be set by, for
-  example:
-
-  --with-pcre2grep-max-bufsize=2097152
-
-  The default is either 1048576 or the value of --with-pcre2grep-bufsize,
-  whichever is the larger.
-
-. It is possible to compile pcre2test so that it links with the libreadline
-  or libedit libraries, by specifying, respectively,
-
-  --enable-pcre2test-libreadline or --enable-pcre2test-libedit
-
-  If this is done, when pcre2test's input is from a terminal, it reads it using
-  the readline() function. This provides line-editing and history facilities.
-  Note that libreadline is GPL-licenced, so if you distribute a binary of
-  pcre2test linked in this way, there may be licensing issues. These can be
-  avoided by linking with libedit (which has a BSD licence) instead.
-
-  Enabling libreadline causes the -lreadline option to be added to the
-  pcre2test build. In many operating environments with a sytem-installed
-  readline library this is sufficient. However, in some environments (e.g. if
-  an unmodified distribution version of readline is in use), it may be
-  necessary to specify something like LIBS="-lncurses" as well. This is
-  because, to quote the readline INSTALL, "Readline uses the termcap functions,
-  but does not link with the termcap or curses library itself, allowing
-  applications which link with readline the to choose an appropriate library."
-  If you get error messages about missing functions tgetstr, tgetent, tputs,
-  tgetflag, or tgoto, this is the problem, and linking with the ncurses library
-  should fix it.
-
-. The C99 standard defines formatting modifiers z and t for size_t and
-  ptrdiff_t values, respectively. By default, PCRE2 uses these modifiers in
-  environments other than Microsoft Visual Studio when __STDC_VERSION__ is
-  defined and has a value greater than or equal to 199901L (indicating C99).
-  However, there is at least one environment that claims to be C99 but does not
-  support these modifiers. If --disable-percent-zt is specified, no use is made
-  of the z or t modifiers. Instead or %td or %zu, %lu is used, with a cast for
-  size_t values.
-
-. There is a special option called --enable-fuzz-support for use by people who
-  want to run fuzzing tests on PCRE2. At present this applies only to the 8-bit
-  library. If set, it causes an extra library called libpcre2-fuzzsupport.a to
-  be built, but not installed. This contains a single function called
-  LLVMFuzzerTestOneInput() whose arguments are a pointer to a string and the
-  length of the string. When called, this function tries to compile the string
-  as a pattern, and if that succeeds, to match it. This is done both with no
-  options and with some random options bits that are generated from the string.
-  Setting --enable-fuzz-support also causes a binary called pcre2fuzzcheck to
-  be created. This is normally run under valgrind or used when PCRE2 is
-  compiled with address sanitizing enabled. It calls the fuzzing function and
-  outputs information about it is doing. The input strings are specified by
-  arguments: if an argument starts with "=" the rest of it is a literal input
-  string. Otherwise, it is assumed to be a file name, and the contents of the
-  file are the test string.
-
-. Releases before 10.30 could be compiled with --disable-stack-for-recursion,
-  which caused pcre2_match() to use individual blocks on the heap for
-  backtracking instead of recursive function calls (which use the stack). This
-  is now obsolete since pcre2_match() was refactored always to use the heap (in
-  a much more efficient way than before). This option is retained for backwards
-  compatibility, but has no effect other than to output a warning.
-
-The "configure" script builds the following files for the basic C library:
-
-. Makefile             the makefile that builds the library
-. src/config.h         build-time configuration options for the library
-. src/pcre2.h          the public PCRE2 header file
-. pcre2-config          script that shows the building settings such as CFLAGS
-                         that were set for "configure"
-. libpcre2-8.pc        )
-. libpcre2-16.pc       ) data for the pkg-config command
-. libpcre2-32.pc       )
-. libpcre2-posix.pc    )
-. libtool              script that builds shared and/or static libraries
-
-Versions of config.h and pcre2.h are distributed in the src directory of PCRE2
-tarballs under the names config.h.generic and pcre2.h.generic. These are
-provided for those who have to build PCRE2 without using "configure" or CMake.
-If you use "configure" or CMake, the .generic versions are not used.
-
-The "configure" script also creates config.status, which is an executable
-script that can be run to recreate the configuration, and config.log, which
-contains compiler output from tests that "configure" runs.
-
-Once "configure" has run, you can run "make". This builds whichever of the
-libraries libpcre2-8, libpcre2-16 and libpcre2-32 are configured, and a test
-program called pcre2test. If you enabled JIT support with --enable-jit, another
-test program called pcre2_jit_test is built as well. If the 8-bit library is
-built, libpcre2-posix and the pcre2grep command are also built. Running
-"make" with the -j option may speed up compilation on multiprocessor systems.
-
-The command "make check" runs all the appropriate tests. Details of the PCRE2
-tests are given below in a separate section of this document. The -j option of
-"make" can also be used when running the tests.
-
-You can use "make install" to install PCRE2 into live directories on your
-system. The following are installed (file names are all relative to the
-<prefix> that is set when "configure" is run):
-
-  Commands (bin):
-    pcre2test
-    pcre2grep (if 8-bit support is enabled)
-    pcre2-config
-
-  Libraries (lib):

-
-If you want to remove PCRE2 from your system, you can run "make uninstall".
-This removes all the files that "make install" installed. However, it does not
-remove any directories, because these are often shared with other programs.
-
-
-Retrieving configuration information
-------------------------------------
-
-Running "make install" installs the command pcre2-config, which can be used to
-recall information about the PCRE2 configuration and installation. For example:
-
-  pcre2-config --version
-
-prints the version number, and
-
-  pcre2-config --libs8
-
-outputs information about where the 8-bit library is installed. This command
-can be included in makefiles for programs that use PCRE2, saving the programmer
-from having to remember too many details. Run pcre2-config with no arguments to
-obtain a list of possible arguments.
-
-The pkg-config command is another system for saving and retrieving information
-about installed libraries. Instead of separate commands for each library, a
-single command is used. For example:
-
-  pkg-config --libs libpcre2-16
-
-The data is held in *.pc files that are installed in a directory called
-<prefix>/lib/pkgconfig.
-
-
-Shared libraries
-----------------
-
-The default distribution builds PCRE2 as shared libraries and static libraries,
-as long as the operating system supports shared libraries. Shared library
-support relies on the "libtool" script which is built as part of the
-"configure" process.
-
-The libtool script is used to compile and link both shared and static
-libraries. They are placed in a subdirectory called .libs when they are newly
-built. The programs pcre2test and pcre2grep are built to use these uninstalled
-libraries (by means of wrapper scripts in the case of shared libraries). When
-you use "make install" to install shared libraries, pcre2grep and pcre2test are
-automatically re-built to use the newly installed shared libraries before being
-installed themselves. However, the versions left in the build directory still
-use the uninstalled libraries.
-
-To build PCRE2 using static libraries only you must use --disable-shared when
-configuring it. For example:
-
-./configure --prefix=/usr/gnu --disable-shared
-
-Then run "make" in the usual way. Similarly, you can use --disable-static to
-build only shared libraries.
-
-
-Cross-compiling using autotools
--------------------------------
-
-You can specify CC and CFLAGS in the normal way to the "configure" command, in
-order to cross-compile PCRE2 for some other host. However, you should NOT
-specify --enable-rebuild-chartables, because if you do, the pcre2_dftables.c
-source file is compiled and run on the local host, in order to generate the
-inbuilt character tables (the pcre2_chartables.c file). This will probably not
-work, because pcre2_dftables.c needs to be compiled with the local compiler,
-not the cross compiler.
-
-When --enable-rebuild-chartables is not specified, pcre2_chartables.c is
-created by making a copy of pcre2_chartables.c.dist, which is a default set of
-tables that assumes ASCII code. Cross-compiling with the default tables should
-not be a problem.
-
-If you need to modify the character tables when cross-compiling, you should
-move pcre2_chartables.c.dist out of the way, then compile pcre2_dftables.c by
-hand and run it on the local host to make a new version of
-pcre2_chartables.c.dist. See the pcre2build section "Creating character tables
-at build time" for more details.
-
-
-Making new tarballs
--------------------
-
-The command "make dist" creates three PCRE2 tarballs, in tar.gz, tar.bz2, and
-zip formats. The command "make distcheck" does the same, but then does a trial
-build of the new distribution to ensure that it works.
-
-If you have modified any of the man page sources in the doc directory, you
-should first run the PrepareRelease script before making a distribution. This
-script creates the .txt and HTML forms of the documentation from the man pages.
-
-
-Testing PCRE2
--------------
-
-To test the basic PCRE2 library on a Unix-like system, run the RunTest script.
-There is another script called RunGrepTest that tests the pcre2grep command.
-When JIT support is enabled, a third test program called pcre2_jit_test is
-built. Both the scripts and all the program tests are run if you obey "make
-check". For other environments, see the instructions in NON-AUTOTOOLS-BUILD.
-
-The RunTest script runs the pcre2test test program (which is documented in its
-own man page) on each of the relevant testinput files in the testdata
-directory, and compares the output with the contents of the corresponding
-testoutput files. RunTest uses a file called testtry to hold the main output
-from pcre2test. Other files whose names begin with "test" are used as working
-files in some tests.
-
-Some tests are relevant only when certain build-time options were selected. For
-example, the tests for UTF-8/16/32 features are run only when Unicode support
-is available. RunTest outputs a comment when it skips a test.
-
-Many (but not all) of the tests that are not skipped are run twice if JIT
-support is available. On the second run, JIT compilation is forced. This
-testing can be suppressed by putting "nojit" on the RunTest command line.
-
-The entire set of tests is run once for each of the 8-bit, 16-bit and 32-bit
-libraries that are enabled. If you want to run just one set of tests, call
-RunTest with either the -8, -16 or -32 option.
-
-If valgrind is installed, you can run the tests under it by putting "valgrind"
-on the RunTest command line. To run pcre2test on just one or more specific test
-files, give their numbers as arguments to RunTest, for example:
-
-  RunTest 2 7 11
-
-You can also specify ranges of tests such as 3-6 or 3- (meaning 3 to the
-end), or a number preceded by ~ to exclude a test. For example:
-
-  Runtest 3-15 ~10
-
-This runs tests 3 to 15, excluding test 10, and just ~13 runs all the tests
-except test 13. Whatever order the arguments are in, the tests are always run
-in numerical order.
-
-You can also call RunTest with the single argument "list" to cause it to output
-a list of tests.
-
-The test sequence starts with "test 0", which is a special test that has no
-input file, and whose output is not checked. This is because it will be
-different on different hardware and with different configurations. The test
-exists in order to exercise some of pcre2test's code that would not otherwise
-be run.
-
-Tests 1 and 2 can always be run, as they expect only plain text strings (not
-UTF) and make no use of Unicode properties. The first test file can be fed
-directly into the perltest.sh script to check that Perl gives the same results.
-The only difference you should see is in the first few lines, where the Perl
-version is given instead of the PCRE2 version. The second set of tests check
-auxiliary functions, error detection, and run-time flags that are specific to
-PCRE2. It also uses the debugging flags to check some of the internals of
-pcre2_compile().
-
-If you build PCRE2 with a locale setting that is not the standard C locale, the
-character tables may be different (see next paragraph). In some cases, this may
-cause failures in the second set of tests. For example, in a locale where the
-isprint() function yields TRUE for characters in the range 128-255, the use of
-[:isascii:] inside a character class defines a different set of characters, and
-this shows up in this test as a difference in the compiled code, which is being
-listed for checking. For example, where the comparison test output contains
-[\x00-\x7f] the test might contain [\x00-\xff], and similarly in some other
-cases. This is not a bug in PCRE2.
-
-Test 3 checks pcre2_maketables(), the facility for building a set of character
-tables for a specific locale and using them instead of the default tables. The
-script uses the "locale" command to check for the availability of the "fr_FR",
-"french", or "fr" locale, and uses the first one that it finds. If the "locale"
-command fails, or if its output doesn't include "fr_FR", "french", or "fr" in
-the list of available locales, the third test cannot be run, and a comment is
-output to say why. If running this test produces an error like this:
-
-  ** Failed to set locale "fr_FR"
-
-it means that the given locale is not available on your system, despite being
-listed by "locale". This does not mean that PCRE2 is broken. There are three
-alternative output files for the third test, because three different versions
-of the French locale have been encountered. The test passes if its output
-matches any one of them.
-
-Tests 4 and 5 check UTF and Unicode property support, test 4 being compatible
-with the perltest.sh script, and test 5 checking PCRE2-specific things.
-
-Tests 6 and 7 check the pcre2_dfa_match() alternative matching function, in
-non-UTF mode and UTF-mode with Unicode property support, respectively.
-
-Test 8 checks some internal offsets and code size features, but it is run only
-when Unicode support is enabled. The output is different in 8-bit, 16-bit, and
-32-bit modes and for different link sizes, so there are different output files
-for each mode and link size.
-
-Tests 9 and 10 are run only in 8-bit mode, and tests 11 and 12 are run only in
-16-bit and 32-bit modes. These are tests that generate different output in
-8-bit mode. Each pair are for general cases and Unicode support, respectively.
-
-Test 13 checks the handling of non-UTF characters greater than 255 by
-pcre2_dfa_match() in 16-bit and 32-bit modes.
-
-Test 14 contains some special UTF and UCP tests that give different output for
-different code unit widths.
-
-Test 15 contains a number of tests that must not be run with JIT. They check,
-among other non-JIT things, the match-limiting features of the intepretive
-matcher.
-
-Test 16 is run only when JIT support is not available. It checks that an
-attempt to use JIT has the expected behaviour.
-
-Test 17 is run only when JIT support is available. It checks JIT complete and
-partial modes, match-limiting under JIT, and other JIT-specific features.
-
-Tests 18 and 19 are run only in 8-bit mode. They check the POSIX interface to
-the 8-bit library, without and with Unicode support, respectively.
-
-Test 20 checks the serialization functions by writing a set of compiled
-patterns to a file, and then reloading and checking them.
-
-Tests 21 and 22 test \C support when the use of \C is not locked out, without
-and with UTF support, respectively. Test 23 tests \C when it is locked out.
-
-Tests 24 and 25 test the experimental pattern conversion functions, without and
-with UTF support, respectively.

-
-Character tables
-----------------
-
-For speed, PCRE2 uses four tables for manipulating and identifying characters
-whose code point values are less than 256. By default, a set of tables that is
-built into the library is used. The pcre2_maketables() function can be called
-by an application to create a new set of tables in the current locale. This are
-passed to PCRE2 by calling pcre2_set_character_tables() to put a pointer into a
-compile context.
-
-The source file called pcre2_chartables.c contains the default set of tables.
-By default, this is created as a copy of pcre2_chartables.c.dist, which
-contains tables for ASCII coding. However, if --enable-rebuild-chartables is
-specified for ./configure, a new version of pcre2_chartables.c is built by the
-program pcre2_dftables (compiled from pcre2_dftables.c), which uses the ANSI C
-character handling functions such as isalnum(), isalpha(), isupper(),
-islower(), etc. to build the table sources. This means that the default C
-locale that is set for your system will control the contents of these default
-tables. You can change the default tables by editing pcre2_chartables.c and
-then re-building PCRE2. If you do this, you should take care to ensure that the
-file does not get automatically re-generated. The best way to do this is to
-move pcre2_chartables.c.dist out of the way and replace it with your customized
-tables.
-
-When the pcre2_dftables program is run as a result of specifying
---enable-rebuild-chartables, it uses the default C locale that is set on your
-system. It does not pay attention to the LC_xxx environment variables. In other
-words, it uses the system's default locale rather than whatever the compiling
-user happens to have set. If you really do want to build a source set of
-character tables in a locale that is specified by the LC_xxx variables, you can
-run the pcre2_dftables program by hand with the -L option. For example:
-
-  ./pcre2_dftables -L pcre2_chartables.c.special
-
-The second argument names the file where the source code for the tables is
-written. The first two 256-byte tables provide lower casing and case flipping
-functions, respectively. The next table consists of a number of 32-byte bit
-maps which identify certain character classes such as digits, "word"
-characters, white space, etc. These are used when building 32-byte bit maps
-that represent character classes for code points less than 256. The final
-256-byte table has bits indicating various character types, as follows:
-
-    1   white space character
-    2   letter
-    4   lower case letter
-    8   decimal digit
-   16   alphanumeric or '_'
-
-You can also specify -b (with or without -L) when running pcre2_dftables. This
-causes the tables to be written in binary instead of as source code. A set of
-binary tables can be loaded into memory by an application and passed to
-pcre2_compile() in the same way as tables created dynamically by calling
-pcre2_maketables(). The tables are just a string of bytes, independent of
-hardware characteristics such as endianness. This means they can be bundled
-with an application that runs in different environments, to ensure consistent
-behaviour.
-
-See also the pcre2build section "Creating character tables at build time".

-<P>
-PCRE2 is the name used for a revised API for the PCRE library, which is a set
-of functions, written in C, that implement regular expression pattern matching
-using the same syntax and semantics as Perl, with just a few differences. After
-nearly two decades, the limitations of the original API were making development
-increasingly difficult. The new API is more extensible, and it was simplified
-by abolishing the separate "study" optimizing function; in PCRE2, patterns are
-automatically optimized where possible. Since forking from PCRE1, the code has
-been extensively refactored and new features introduced.
-</P>
-<P>
-As well as Perl-style regular expression patterns, some features that appeared
-in Python and the original PCRE before they appeared in Perl are available
-using the Python syntax. There is also some support for one or two .NET and
-Oniguruma syntax items, and there are options for requesting some minor changes
-that give better ECMAScript (aka JavaScript) compatibility.
-</P>
-<P>
-The source code for PCRE2 can be compiled to support strings of 8-bit, 16-bit,
-or 32-bit code units, which means that up to three separate libraries may be
-installed, one for each code unit size. The size of code unit is not related to
-the bit size of the underlying hardware. In a 64-bit environment that also
-supports 32-bit applications, versions of PCRE2 that are compiled in both
-64-bit and 32-bit modes may be needed.
-</P>
-<P>
-The original work to extend PCRE to 16-bit and 32-bit code units was done by
-Zoltan Herczeg and Christian Persch, respectively. In all three cases, strings
-can be interpreted either as one character per code unit, or as UTF-encoded
-Unicode, with support for Unicode general category properties. Unicode support
-is optional at build time (but is the default). However, processing strings as
-UTF code units must be enabled explicitly at run time. The version of Unicode
-in use can be discovered by running
-<pre>
-  pcre2test -C
-</PRE>
-</P>
-<P>
-The three libraries contain identical sets of functions, with names ending in
-_8, _16, or _32, respectively (for example, <b>pcre2_compile_8()</b>). However,
-by defining PCRE2_CODE_UNIT_WIDTH to be 8, 16, or 32, a program that uses just
-one code unit width can be written using generic names such as
-<b>pcre2_compile()</b>, and the documentation is written assuming that this is
-the case.
-</P>
-<P>
-In addition to the Perl-compatible matching function, PCRE2 contains an
-alternative function that matches the same compiled patterns in a different
-way. In certain circumstances, the alternative function has some advantages.
-For a discussion of the two matching algorithms, see the
-<a href="pcre2matching.html"><b>pcre2matching</b></a>
-page.
-</P>
-<P>
-Details of exactly which Perl regular expression features are and are not
-supported by PCRE2 are given in separate documents. See the
-<a href="pcre2pattern.html"><b>pcre2pattern</b></a>
-and
-<a href="pcre2compat.html"><b>pcre2compat</b></a>
-pages. There is a syntax summary in the
-<a href="pcre2syntax.html"><b>pcre2syntax</b></a>
-page.
-</P>
-<P>
-Some features of PCRE2 can be included, excluded, or changed when the library
-is built. The
-<a href="pcre2_config.html"><b>pcre2_config()</b></a>
-function makes it possible for a client to discover which features are
-available. The features themselves are described in the
-<a href="pcre2build.html"><b>pcre2build</b></a>
-page. Documentation about building PCRE2 for various operating systems can be
-found in the
-<a href="README.txt"><b>README</b></a>
-and
-<a href="NON-AUTOTOOLS-BUILD.txt"><b>NON-AUTOTOOLS_BUILD</b></a>
-files in the source distribution.
-</P>
-<P>
-The libraries contains a number of undocumented internal functions and data
-tables that are used by more than one of the exported external functions, but
-which are not intended for use by external callers. Their names all begin with
-"_pcre2", which hopefully will not provoke any name clashes. In some
-environments, it is possible to control which external symbols are exported
-when a shared library is built, and in these cases the undocumented symbols are
-not exported.
-</P>
-<br><a name="SEC2" href="#TOC1">SECURITY CONSIDERATIONS</a><br>
-<P>
-If you are using PCRE2 in a non-UTF application that permits users to supply
-arbitrary patterns for compilation, you should be aware of a feature that
-allows users to turn on UTF support from within a pattern. For example, an
-8-bit pattern that begins with "(*UTF)" turns on UTF-8 mode, which interprets
-patterns and subjects as strings of UTF-8 code units instead of individual
-8-bit characters. This causes both the pattern and any data against which it is
-matched to be checked for UTF-8 validity. If the data string is very long, such
-a check might use sufficiently many resources as to cause your application to
-lose performance.
-</P>
-<P>
-One way of guarding against this possibility is to use the
-<b>pcre2_pattern_info()</b> function to check the compiled pattern's options for
-PCRE2_UTF. Alternatively, you can set the PCRE2_NEVER_UTF option when calling
-<b>pcre2_compile()</b>. This causes a compile time error if the pattern contains
-a UTF-setting sequence.
-</P>
-<P>
-The use of Unicode properties for character types such as \d can also be
-enabled from within the pattern, by specifying "(*UCP)". This feature can be
-disallowed by setting the PCRE2_NEVER_UCP option.
-</P>
-<P>
-If your application is one that supports UTF, be aware that validity checking
-can take time. If the same data string is to be matched many times, you can use
-the PCRE2_NO_UTF_CHECK option for the second and subsequent matches to avoid
-running redundant checks.
-</P>
-<P>
-The use of the \C escape sequence in a UTF-8 or UTF-16 pattern can lead to
-problems, because it may leave the current matching point in the middle of a
-multi-code-unit character. The PCRE2_NEVER_BACKSLASH_C option can be used by an
-application to lock out the use of \C, causing a compile-time error if it is
-encountered. It is also possible to build PCRE2 with the use of \C permanently
-disabled.
-</P>
-<P>
-Another way that performance can be hit is by running a pattern that has a very
-large search tree against a string that will never match. Nested unlimited
-repeats in a pattern are a common example. PCRE2 provides some protection
-against this: see the <b>pcre2_set_match_limit()</b> function in the
-<a href="pcre2api.html"><b>pcre2api</b></a>
-page. There is a similar function called <b>pcre2_set_depth_limit()</b> that can
-be used to restrict the amount of memory that is used.
-</P>
-<br><a name="SEC3" href="#TOC1">USER DOCUMENTATION</a><br>
-<P>
-The user documentation for PCRE2 comprises a number of different sections. In
-the "man" format, each of these is a separate "man page". In the HTML format,
-each is a separate page, linked from the index page. In the plain text format,
-the descriptions of the <b>pcre2grep</b> and <b>pcre2test</b> programs are in
-files called <b>pcre2grep.txt</b> and <b>pcre2test.txt</b>, respectively. The
-remaining sections, except for the <b>pcre2demo</b> section (which is a program
-listing), and the short pages for individual functions, are concatenated in

-DESCRIPTION
-</b><br>
-<P>
-This function scans a compiled regular expression and calls the <i>callback()</i>
-function for each callout within the pattern. The yield of the function is zero
-for success and non-zero otherwise. The arguments are:
-<pre>
-  <i>code</i>           Points to the compiled pattern
-  <i>callback</i>       The callback function
-  <i>callout_data</i>   User data that is passed to the callback
-</pre>
-The <i>callback()</i> function is passed a pointer to a data block containing
-the following fields (not necessarily in this order):
-<pre>
-  uint32_t   <i>version</i>                Block version number
-  uint32_t   <i>callout_number</i>         Number for numbered callouts
-  PCRE2_SIZE <i>pattern_position</i>       Offset to next item in pattern
-  PCRE2_SIZE <i>next_item_length</i>       Length of next item in pattern
-  PCRE2_SIZE <i>callout_string_offset</i>  Offset to string within pattern
-  PCRE2_SIZE <i>callout_string_length</i>  Length of callout string
-  PCRE2_SPTR <i>callout_string</i>         Points to callout string or is NULL
-</pre>
-The second argument passed to the <b>callback()</b> function is the callout data
-that was passed to <b>pcre2_callout_enumerate()</b>. The <b>callback()</b>
-function must return zero for success. Any other value causes the pattern scan
-to stop, with the value being passed back as the result of

-This function makes a copy of the memory used for a compiled pattern, excluding

-<P>
-This function compiles a regular expression pattern into an internal form. Its
-arguments are:
-<pre>
-  <i>pattern</i>       A string containing expression to be compiled
-  <i>length</i>        The length of the string or PCRE2_ZERO_TERMINATED
-  <i>options</i>       Option bits
-  <i>errorcode</i>     Where to put an error code
-  <i>erroffset</i>     Where to put an error offset
-  <i>ccontext</i>      Pointer to a compile context or NULL
-</pre>
-The length of the pattern and any error offset that is returned are in code
-units, not characters. A compile context is needed only if you want to provide
-custom memory allocation functions, or to provide an external function for
-system stack size checking, or to change one or more of these parameters:
-<pre>
-  What \R matches (Unicode newlines, or CR, LF, CRLF only);
-  PCRE2's character tables;
-  The newline character sequence;
-  The compile time nested parentheses limit;
-  The maximum pattern length (in code units) that is allowed.
-  The additional options bits (see pcre2_set_compile_extra_options())
-</pre>
-The option bits are:
-<pre>
-  PCRE2_ANCHORED           Force pattern anchoring
-  PCRE2_ALLOW_EMPTY_CLASS  Allow empty classes
-  PCRE2_ALT_BSUX           Alternative handling of \u, \U, and \x

-  PCRE2_CASELESS           Do caseless matching
-  PCRE2_DOLLAR_ENDONLY     $ not to match newline at end
-  PCRE2_DOTALL             . matches anything including NL
-  PCRE2_DUPNAMES           Allow duplicate names for subpatterns
-  PCRE2_ENDANCHORED        Pattern can match only at end of subject
-  PCRE2_EXTENDED           Ignore white space and # comments
-  PCRE2_FIRSTLINE          Force matching to be before newline
-  PCRE2_LITERAL            Pattern characters are all literal
-  PCRE2_MATCH_INVALID_UTF  Enable support for matching invalid UTF
-  PCRE2_MATCH_UNSET_BACKREF  Match unset backreferences
-  PCRE2_MULTILINE          ^ and $ match newlines within data
-  PCRE2_NEVER_BACKSLASH_C  Lock out the use of \C in patterns
-  PCRE2_NEVER_UCP          Lock out PCRE2_UCP, e.g. via (*UCP)
-  PCRE2_NEVER_UTF          Lock out PCRE2_UTF, e.g. via (*UTF)
-  PCRE2_NO_AUTO_CAPTURE    Disable numbered capturing paren-
-                            theses (named ones available)
-  PCRE2_NO_AUTO_POSSESS    Disable auto-possessification
-  PCRE2_NO_DOTSTAR_ANCHOR  Disable automatic anchoring for .*
-  PCRE2_NO_START_OPTIMIZE  Disable match-time start optimizations
-  PCRE2_NO_UTF_CHECK       Do not check the pattern for UTF validity
-                             (only relevant if PCRE2_UTF is set)
-  PCRE2_UCP                Use Unicode properties for \d, \w, etc.
-  PCRE2_UNGREEDY           Invert greediness of quantifiers
-  PCRE2_USE_OFFSET_LIMIT   Enable offset limit for unanchored matching
-  PCRE2_UTF                Treat pattern and subjects as UTF strings
-</pre>
-PCRE2 must be built with Unicode support (the default) in order to use
-PCRE2_UTF, PCRE2_UCP and related options.

-<P>
-This function makes it possible for a client program to find out which optional
-features are available in the version of the PCRE2 library it is using. The
-arguments are as follows:
-<pre>
-  <i>what</i>     A code specifying what information is required
-  <i>where</i>    Points to where to put the information
-</pre>
-If <i>where</i> is NULL, the function returns the amount of memory needed for
-the requested information. When the information is a string, the value is in
-code units; for other types of data it is in bytes.
-</P>
-<P>
-If <b>where</b> is not NULL, for PCRE2_CONFIG_JITTARGET,
-PCRE2_CONFIG_UNICODE_VERSION, and PCRE2_CONFIG_VERSION it must point to a
-buffer that is large enough to hold the string. For all other codes it must
-point to a uint32_t integer variable. The available codes are:
-<pre>
-  PCRE2_CONFIG_BSR             Indicates what \R matches by default:
-                                 PCRE2_BSR_UNICODE

-  PCRE2_CONFIG_DEPTHLIMIT      Default backtracking depth limit
-  PCRE2_CONFIG_HEAPLIMIT       Default heap memory limit
-  PCRE2_CONFIG_JIT             Availability of just-in-time compiler support (1=yes 0=no)
-  PCRE2_CONFIG_JITTARGET       Information (a string) about the target architecture for the JIT compiler
-  PCRE2_CONFIG_LINKSIZE        Configured internal link size (2, 3, 4)
-  PCRE2_CONFIG_MATCHLIMIT      Default internal resource limit
-  PCRE2_CONFIG_NEVER_BACKSLASH_C  Whether or not \C is disabled
-  PCRE2_CONFIG_NEWLINE         Code for the default newline sequence:
-                                 PCRE2_NEWLINE_CR
-                                 PCRE2_NEWLINE_LF

-  PCRE2_CONFIG_RECURSIONLIMIT  Obsolete: use PCRE2_CONFIG_DEPTHLIMIT
-  PCRE2_CONFIG_STACKRECURSE    Obsolete: always returns 0
-  PCRE2_CONFIG_UNICODE         Availability of Unicode support (1=yes 0=no)
-  PCRE2_CONFIG_UNICODE_VERSION The Unicode version (a string)
-  PCRE2_CONFIG_VERSION         The PCRE2 version (a string)
-</pre>
-The function yields a non-negative value on success or the negative value
-PCRE2_ERROR_BADOPTION otherwise. This is also the result for the
-PCRE2_CONFIG_JITTARGET code if JIT support is not available. When a string is
-requested, the function returns the number of code units used, including the

-DESCRIPTION
-</b><br>
-<P>
-This function matches a compiled regular expression against a given subject
-string, using an alternative matching algorithm that scans the subject string
-just once (except when processing lookaround assertions). This function is
-<i>not</i> Perl-compatible (the Perl-compatible matching function is
-<b>pcre2_match()</b>). The arguments for this function are:
-<pre>
-  <i>code</i>         Points to the compiled pattern
-  <i>subject</i>      Points to the subject string
-  <i>length</i>       Length of the subject string
-  <i>startoffset</i>  Offset in the subject at which to start matching
-  <i>options</i>      Option bits
-  <i>match_data</i>   Points to a match data block, for results
-  <i>mcontext</i>     Points to a match context, or is NULL
-  <i>workspace</i>    Points to a vector of ints used as working space
-  <i>wscount</i>      Number of elements in the vector
-</pre>
-For <b>pcre2_dfa_match()</b>, a match context is needed only if you want to set
-up a callout function or specify the heap limit or the match or the recursion
-depth limits. The <i>length</i> and <i>startoffset</i> values are code units, not
-characters. The options are:
-<pre>
-  PCRE2_ANCHORED          Match only at the first position
-  PCRE2_COPY_MATCHED_SUBJECT
-                          On success, make a private subject copy
-  PCRE2_ENDANCHORED       Pattern can match only at end of subject
-  PCRE2_NOTBOL            Subject is not the beginning of a line
-  PCRE2_NOTEOL            Subject is not the end of a line
-  PCRE2_NOTEMPTY          An empty string is not a valid match
-  PCRE2_NOTEMPTY_ATSTART  An empty string at the start of the subject is not a valid match
-  PCRE2_NO_UTF_CHECK      Do not check the subject for UTF validity (only relevant if PCRE2_UTF
-                           was set at compile time)
-  PCRE2_PARTIAL_HARD      Return PCRE2_ERROR_PARTIAL for a partial match even if there is a full match
-  PCRE2_PARTIAL_SOFT      Return PCRE2_ERROR_PARTIAL for a partial match if no full matches are found
-  PCRE2_DFA_RESTART       Restart after a partial match
-  PCRE2_DFA_SHORTEST      Return only the shortest match
-</pre>

-<br><b>
-DESCRIPTION
-</b><br>
-<P>
-This function provides control over the memory used by JIT as a run-time stack
-when <b>pcre2_match()</b> or <b>pcre2_jit_match()</b> is called with a pattern
-that has been successfully processed by the JIT compiler. The information that
-determines which stack is used is put into a match context that is subsequently
-passed to a matching function. The arguments of this function are:
-<pre>
-  mcontext       a pointer to a match context
-  callback       a callback function
-  callback_data  a JIT stack or a value to be passed to the callback
-</PRE>
-</P>
-<P>
-If <i>mcontext</i> is NULL, the function returns immediately, without doing
-anything.
-</P>
-<P>
-If <i>callback</i> is NULL and <i>callback_data</i> is NULL, an internal 32KiB
-block on the machine stack is used.
-</P>
-<P>
-If <i>callback</i> is NULL and <i>callback_data</i> is not NULL,
-<i>callback_data</i> must be a valid JIT stack, the result of calling
-<b>pcre2_jit_stack_create()</b>.
-</P>
-<P>
-If <i>callback</i> not NULL, it is called with <i>callback_data</i> as an
-argument at the start of matching, in order to set up a JIT stack. If the
-result is NULL, the internal 32KiB stack is used; otherwise the return value
-must be a valid JIT stack, the result of calling
-<b>pcre2_jit_stack_create()</b>.
-</P>
-<P>
-You may safely use the same JIT stack for multiple patterns, as long as they
-are all matched in the same thread. In a multithread application, each thread
-must use its own JIT stack. For more details, see the

-DESCRIPTION

-<P>
-This function is used to create a stack for use by the code compiled by the JIT

-DESCRIPTION
-</b><br>
-<P>
-This function matches a compiled regular expression against a given subject
-string, using a matching algorithm that is similar to Perl's. It returns
-offsets to what it has matched and to captured substrings via the
-<b>match_data</b> block, which can be processed by functions with names that
-start with <b>pcre2_get_ovector_...()</b> or <b>pcre2_substring_...()</b>. The
-return from <b>pcre2_match()</b> is one more than the highest numbered capturing
-pair that has been set (for example, 1 if there are no captures), zero if the
-vector of offsets is too small, or a negative error code for no match and other
-errors. The function arguments are:
-<pre>
-  <i>code</i>         Points to the compiled pattern
-  <i>subject</i>      Points to the subject string
-  <i>length</i>       Length of the subject string
-  <i>startoffset</i>  Offset in the subject at which to start matching
-  <i>options</i>      Option bits
-  <i>match_data</i>   Points to a match data block, for results
-  <i>mcontext</i>     Points to a match context, or is NULL
-</pre>
-A match context is needed only if you want to:
-<pre>
-  Set up a callout function
-  Set a matching offset limit
-  Change the heap memory limit
-  Change the backtracking match limit
-  Change the backtracking depth limit
-  Set custom memory management specifically for the match
-</pre>
-The <i>length</i> and <i>startoffset</i> values are code units, not characters.
-The length may be given as PCRE2_ZERO_TERMINATED for a subject that is
-terminated by a binary zero code unit. The options are:
-<pre>
-  PCRE2_ANCHORED          Match only at the first position
-  PCRE2_COPY_MATCHED_SUBJECT
-                          On success, make a private subject copy
-  PCRE2_ENDANCHORED       Pattern can match only at end of subject
-  PCRE2_NOTBOL            Subject string is not the beginning of a line
-  PCRE2_NOTEOL            Subject string is not the end of a line
-  PCRE2_NOTEMPTY          An empty string is not a valid match
-  PCRE2_NOTEMPTY_ATSTART  An empty string at the start of the subject is not a valid match
-  PCRE2_NO_JIT            Do not use JIT matching
-  PCRE2_NO_UTF_CHECK      Do not check the subject for UTF validity (only relevant if PCRE2_UTF
-                           was set at compile time)
-  PCRE2_PARTIAL_HARD      Return PCRE2_ERROR_PARTIAL for a partial match even if there is a full match

-The length of the converted pattern (excluding the terminating zero) is
-returned via <i>blength</i>. If <i>buffer</i> is NULL, the function just returns
-the output length. If <i>buffer</i> points to a NULL pointer, heap memory is
-obtained for the converted pattern, using the allocator in the context if
-present (or else <b>malloc()</b>), and the field pointed to by <i>buffer</i> is
-updated. If <i>buffer</i> points to a non-NULL field, that must point to a
-buffer whose size is in the variable pointed to by <i>blength</i>. This value is
-updated.

-<P>
-This function encodes a list of compiled patterns into a byte stream that can

-can only happen on a host that is running the same version of PCRE2, with the

-  <i>codes</i>             pointer to a vector containing the list
-  <i>number_of_codes</i>   number of slots in the vector

-  <i>serialized_size</i>   set to the number of bytes in the byte stream
-  <i>gcontext</i>          pointer to a general context or NULL
-</pre>
-The context argument is used to obtain memory for the byte stream. When the
-serialized data is no longer needed, it must be freed by calling
-<b>pcre2_serialize_free()</b>. The yield of the function is the number of
-serialized patterns, or one of the following negative error codes:
-<pre>
-  PCRE2_ERROR_BADDATA      <i>number_of_codes</i> is zero or less
-  PCRE2_ERROR_BADMAGIC     mismatch of id bytes in one of the patterns
-  PCRE2_ERROR_MEMORY       memory allocation failed
-  PCRE2_ERROR_MIXEDTABLES  the patterns do not all use the same tables
-  PCRE2_ERROR_NULL         an argument other than <i>gcontext</i> is NULL
-</pre>

-DESCRIPTION

-<P>
-This function defines, within a compile context, a function that is called

-non-zero to force an error. This feature is provided so that applications can
-check the available system stack space, in order to avoid running out. The
-result of <b>pcre2_set_compile_recursion_guard()</b> is always zero.
