+CC0 1.0 Universal
+
+Statement of Purpose
+
+The laws of most jurisdictions throughout the world automatically confer
+exclusive Copyright and Related Rights (defined below) upon the creator and
+subsequent owner(s) (each and all, an "owner") of an original work of
+authorship and/or a database (each, a "Work").
+
+Certain owners wish to permanently relinquish those rights to a Work for the
+purpose of contributing to a commons of creative, cultural and scientific
+works ("Commons") that the public can reliably and without fear of later
+claims of infringement build upon, modify, incorporate in other works, reuse
+and redistribute as freely as possible in any form whatsoever and for any
+purposes, including without limitation commercial purposes. These owners may
+contribute to the Commons to promote the ideal of a free culture and the
+further production of creative, cultural and scientific works, or to gain
+reputation or greater distribution for their Work in part through the use and
+efforts of others.
+
+For these and/or other purposes and motivations, and without any expectation
+of additional consideration or compensation, the person associating CC0 with a
+Work (the "Affirmer"), to the extent that he or she is an owner of Copyright
+and Related Rights in the Work, voluntarily elects to apply CC0 to the Work
+and publicly distribute the Work under its terms, with knowledge of his or her
+Copyright and Related Rights in the Work and the meaning and intended legal
+effect of CC0 on those rights.
+
+1. Copyright and Related Rights. A Work made available under CC0 may be
+protected by copyright and related or neighboring rights ("Copyright and
+Related Rights"). Copyright and Related Rights include, but are not limited
+to, the following:
+
+  i. the right to reproduce, adapt, distribute, perform, display, communicate,
+  and translate a Work;
+
+  ii. moral rights retained by the original author(s) and/or performer(s);
+
+  iii. publicity and privacy rights pertaining to a person's image or likeness
+  depicted in a Work;
+
+  iv. rights protecting against unfair competition in regards to a Work,
+  subject to the limitations in paragraph 4(a), below;
+
+  v. rights protecting the extraction, dissemination, use and reuse of data in
+  a Work;
+
+  vi. database rights (such as those arising under Directive 96/9/EC of the
+  European Parliament and of the Council of 11 March 1996 on the legal
+  protection of databases, and under any national implementation thereof,
+  including any amended or successor version of such directive); and
+
+  vii. other similar, equivalent or corresponding rights throughout the world
+  based on applicable law or treaty, and any national implementations thereof.
+
+2. Waiver. To the greatest extent permitted by, but not in contravention of,
+applicable law, Affirmer hereby overtly, fully, permanently, irrevocably and
+unconditionally waives, abandons, and surrenders all of Affirmer's Copyright
+and Related Rights and associated claims and causes of action, whether now
+known or unknown (including existing as well as future claims and causes of
+action), in the Work (i) in all territories worldwide, (ii) for the maximum
+duration provided by applicable law or treaty (including future time
+extensions), (iii) in any current or future medium and for any number of
+copies, and (iv) for any purpose whatsoever, including without limitation
+commercial, advertising or promotional purposes (the "Waiver"). Affirmer makes
+the Waiver for the benefit of each member of the public at large and to the
+detriment of Affirmer's heirs and successors, fully intending that such Waiver
+shall not be subject to revocation, rescission, cancellation, termination, or
+any other legal or equitable action to disrupt the quiet enjoyment of the Work
+by the public as contemplated by Affirmer's express Statement of Purpose.
+
+3. Public License Fallback. Should any part of the Waiver for any reason be
+judged legally invalid or ineffective under applicable law, then the Waiver
+shall be preserved to the maximum extent permitted taking into account
+Affirmer's express Statement of Purpose. In addition, to the extent the Waiver
+is so judged Affirmer hereby grants to each affected person a royalty-free,
+non transferable, non sublicensable, non exclusive, irrevocable and
+unconditional license to exercise Affirmer's Copyright and Related Rights in
+the Work (i) in all territories worldwide, (ii) for the maximum duration
+provided by applicable law or treaty (including future time extensions), (iii)
+in any current or future medium and for any number of copies, and (iv) for any
+purpose whatsoever, including without limitation commercial, advertising or
+promotional purposes (the "License"). The License shall be deemed effective as
+of the date CC0 was applied by Affirmer to the Work. Should any part of the
+License for any reason be judged legally invalid or ineffective under
+applicable law, such partial invalidity or ineffectiveness shall not
+invalidate the remainder of the License, and in such case Affirmer hereby
+affirms that he or she will not (i) exercise any of his or her remaining
+Copyright and Related Rights in the Work or (ii) assert any associated claims
+and causes of action with respect to the Work, in either case contrary to
+Affirmer's express Statement of Purpose.
+
+4. Limitations and Disclaimers.
+
+  a. No trademark or patent rights held by Affirmer are waived, abandoned,
+  surrendered, licensed or otherwise affected by this document.
+
+  b. Affirmer offers the Work as-is and makes no representations or warranties
+  of any kind concerning the Work, express, implied, statutory or otherwise,
+  including without limitation warranties of title, merchantability, fitness
+  for a particular purpose, non infringement, or the absence of latent or
+  other defects, accuracy, or the present or absence of errors, whether or not
+  discoverable, all to the greatest extent permissible under applicable law.
+
+  c. Affirmer disclaims responsibility for clearing rights of other persons
+  that may apply to the Work or any use thereof, including without limitation
+  any person's Copyright and Related Rights in the Work. Further, Affirmer
+  disclaims responsibility for obtaining any necessary consents, permissions
+  or other rights required for any use of the Work.
+
+  d. Affirmer understands and acknowledges that Creative Commons is not a
+  party to this document and has no duty or obligation with respect to this
+  CC0 or use of the Work.

+Thank you for helping us improve libarchive.
+The following guidelines will help ensure your contribution gets prompt attention.
+
+# Bugs and other Issues
+
+If you encounter any problems with libarchive,
+[please file an issue on our issue tracker](https://github.com/libarchive/libarchive/issues).
+
+All bug reports should include the following information.  You can copy the text below directly into the issue tracker to get started:
+
+```
+Basic Information
+  Version of libarchive:
+  How you obtained it:  (build from source, pre-packaged binary, etc)
+  Operating system and version:
+  What compiler and/or IDE you are using (include version):
+
+If you are using a pre-packaged binary
+  Exact package name and version:
+  Repository you obtained it from:
+
+Description of the problem you are seeing:
+  What did you do?
+  What did you expect to happen?
+  What actually happened?
+  What log files or error messages were produced?
+
+How the libarchive developers can reproduce your problem:
+  What other software was involved?
+  What other files were involved?
+  How can we obtain any of the above?
+```
+
+Depending on the specific type of issue, other information will be helpful:
+
+## Test Failures
+
+If you see any test failures, please include the information above and also:
+
+* Names of the tests that failed.
+
+* Look for the .log files in the /tmp/libarchive_test_*date-and-time* directories.  (On Mac OS, look in $TMPDIR which is different than /tmp.)
+
+Please paste the .log files you will find there directly into your report.
+
+
+## Problems using libarchive in a program
+
+If you are trying to write a program using libarchive, please include the information above and also:
+
+* It will help us if we can actually run the program.  This is easiest if you can provide source to a short program that illustrates your problem.
+
+* If you have a sufficiently short program that shows the problem, you can either paste it into the report or [put it into a gist](https://gist.github.com).
+
+
+## Libarchive produced incorrect output
+
+Please tell us what program you ran, any command-line arguments you provided, and details of the input files (`ls -l` output is helpful here).  If the problem involved a command-line program, please copy the full terminal text into the report, including the command line and any error messages.
+
+Please try to make the output file available to us.  Unless it is very large, you can upload it into a fresh github repository and provide a link in your issue report.
+
+
+## Libarchive could not read a particular input file
+
+Note: If you can provide a **very small** input file that reproduces the problem, we can add that to our test suite.  This will ensure that the bug does not reappear in the future.
+
+A link to the relevant file is usually sufficient.
+
+If you cannot provide the input file or a link to the file, please let us know if there is some other way to obtain it.
+
+
+## Documentation improvements
+
+We are always interested in improving the libarchive documentation.  Please tell us about any errors you find, including:
+
+* Typos or errors in the manpages provided with libarchive source.
+
+* Mistakes in the [libarchive Wiki](https://github.com/libarchive/libarchive/wiki)
+
+* Problems with the PDF or Wiki files that are automatically generated from the manpages.
+
+
+# Code Submissions
+
+We welcome all code submissions.  But of course, some code submissions are easier for us to respond to than others. The best code submissions:
+
+* Address a single issue.  There have been many cases where a simple fix to an obvious problem did not get handled for months because the patch that was provided also included an unrelated change affecting an especially complex area of the code.
+
+* Follow existing libarchive code style and conventions.  Libarchive generally follows [BSD KNF](https://www.freebsd.org/cgi/man.cgi?query=style&sektion=9) for formatting code.
+
+* Do not make unnecessary changes to existing whitespace, capitalization, or spelling.
+
+* Include detailed instructions for reproducing the problem you're fixing.  We do try to verify that a submission actually fixes a real problem.  If we can't reproduce the problem, it will take us longer to evaluate the fix.  For this reason, we encourage you to file an issue report first with details on reproducing the problem, then refer to that issue in your pull request.
+
+* Includes a test case.  The libarchive Wiki has [detailed documentation for adding new test cases](https://github.com/libarchive/libarchive/wiki/LibarchiveAddingTest).
+
+* Are provided via Github pull requests.  We welcome patches in almost any format, but github's pull request management makes it significantly easier for us to evaluate and test changes.

+More complete build documentation is available on the libarchive
+Wiki:  https://github.com/libarchive/libarchive/wiki
+
+On most Unix-like systems, you should be able to install libarchive,
+bsdtar, and bsdcpio using the following common steps:
+    ./configure
+    make
+    make install
+
+If you need to customize the target directories or otherwise adjust
+the build setting, use
+    ./configure --help
+to list the configure options.
+
+If you are developing libarchive and need to update the
+configure script and other build files:
+    /bin/sh build/autogen.sh
+
+To create a distribution, please use the 'distcheck' target:
+    /bin/sh build/autogen.sh && ./configure && make distcheck
+
+On Unix-like and non-Unix-like systems, use the "cmake" utility (available from
+http://cmake.org/) to generate suitable build files for your platform.
+Cmake requires the name of the directory containing CmakeLists.txt and
+the "generator" to use for your build environment.  For example, to
+build with Xcode on Mac OS, you can use the following command:
+    cmake -G "Xcode" ~/libarchive-download-dir/
+The result will be appropriate makefiles, solution files, or project
+files that can be used with the corresponding development tool.
+The default on Unix-like systems is to generate Makefiles, so you
+can also use cmake instead of the configure script:
+    cmake ~/libarchive-download-dir/
+    make
+    make install
+See the libarchive Wiki or the cmake site for further documentation.

+Jan 07, 2009: New archive_read_disk_entry_from_file() knows about ACLs,
+	extended attributes, etc so that bsdtar and bsdcpio don't require
+	such system-specific knowledge.
+Jan 03, 2009: Read filter system extensively refactored.  In particular,
+	read filter pipelines are now built out automatically and individual
+	filters should be much easier to implement.  Documentation on the

+Dec 28, 2008: Many Windows/Visual Studio fixes from Michihiro NAKAJIMA.
+
+Dec 28, 2008: Main libarchive development moved from FreeBSD Perforce

+Nov 08, 2008: Start of pre-release testing for libarchive 2.6
+
+Nov 07, 2008: Read filter refactor: The decompression routines just
+	consume and produce arbitrarily-sized blocks.  The reblocking
+	from read_support_compression_none() has been pulled into the
+	read core.  Also, the decompression bid now makes multiple
+	passes and stacks read filters.
+Oct 21, 2008: bsdcpio: New command-line parser.
+Oct 19, 2008: Internal read_ahead change: short reads are now an error
+Oct 06, 2008: bsdtar: option parser no longer uses getopt_long(),
+	gives consistent option parsing on all platforms.
+Sep 19, 2008: Jaakko Heinonen: shar utility built on libarchive
+Sep 17, 2008: Pedro Giffuni: birthtime support
+Sep 17, 2008: Miklos Vajna: lzma reader and test.  Note:  I still have
+	some concerns about the auto-detection (LZMA file format
+	doesn't support auto-detection well), so this is not yet
+	enabled under archive_read_support_compression_all().  For
+	now, you must call archive_read_support_compression_lzma() if
+	you want LZMA read support.
+Sep 11, 2008: Ivailo Petrov: Many fixes to Windows build, new solution files
+Jul 26, 2008: archive_entry now tracks which values have not been set.
+	This helps zip extraction (file size is often "unknown") and
+	time restores (tar usually doesn't know atime).
+Jul 26, 2008: Joerg Sonnenberger: Performance improvements to shar writer
+Jul 25, 2008: Joerg Sonnenberger: mtree write support
+
+Jul 02, 2008: libarchive 2.5.5 released
+
+Jul 02, 2008: libarchive 2.5.5b released
+Jul 01, 2008: bsdcpio is being used by enough people, we can call it 1.0.0 now
+Jun 20, 2008: bsdcpio: If a -l link fails with EXDEV, copy the file instead
+Jun 19, 2008: bsdcpio: additional long options for better GNU cpio compat
+Jun 15, 2008: Many small portability and bugfixes since 2.5.4b.
+
+May 25, 2008: libarchive 2.5.4b released
+May 21, 2008: Joerg Sonnenberger: fix bsdtar hardlink handling for newc format
+
+May 21, 2008: More progress on Windows building.  Thanks to "Scott"
+        for the Windows makefiles, thanks to Kees Zeelenberg for
+        code contributions.
+
+May 21, 2008: Fix a number of non-exploitable integer and buffer overflows,
+        thanks to David Remahl at Apple for pointing these out.
+
+May 21, 2008: Colin Percival: SIGINFO or SIGUSR1 to bsdtar prints progress info
+
+May 16, 2008: bsdtar's test harness no longer depends on file ordering.
+        This was causing spurious test failures on a lot of systems.
+        Thanks to Bernhard R. Link for the diagnosis.
+
+May 14, 2008: Joerg Sonnenberger: -s substitution support for bsdtar
+
+May 13, 2008: Joerg Sonnenberger: Many mtree improvements
+
+May 11, 2008: Joerg Sonnenberger: fix hardlink extraction when
+	hardlinks have different permissions from original file
+
+April 30, 2008: Primary libarchive work has been moved into the FreeBSD
+	project's Perforce repository: 	http://perforce.freebsd.org/
+	The libarchive project can be browsed at
+        //depot/user/kientzle/libarchive-portable
+        Direct link: http://preview.tinyurl.com/46mdgr
+
+May 04, 2008: libarchive 2.5.3b released
+	* libarchive: Several fixes to link resolver to address bsdcpio crashes
+	* bsdcpio: -p hardlink handling fixes
+	* tar/pax: Ensure ustar dirnames end in '/'; be more careful about
+	  measuring filenames when deciding what pathname fields to use
+	* libarchive: Mark which entry strings are set; be accurate about
+	  distinguishing empty strings ("") from unset ones (NULL)
+	* tar: Don't crash reading entries with empty filenames
+	* libarchive_test, bsdtar_test, bsdcpio_test:  Better defaults:
+	  run all tests, delete temp dirs, summarize repeated failures
+	* -no-undefined to libtool for Cygwin
+	* libarchive_test: Skip large file tests on systems with 32-bit off_t
+	* iso9660: Don't bother trying to find the body of an empty file;
+	  this works around strange behavior from some ISO9660 writers
+	* tar: allow -r -T to be used together
+	* tar: allow --format with -r or -u
+	* libarchive: Don't build archive.h
+
+May 04, 2008: Simplified building: archive.h is no longer constructed
+	This may require additional #if conditionals on some platforms.
+
+Mar 30, 2008: libarchive 2.5.1b released
+
+Mar 15, 2008: libarchive 2.5.0b released
+Mar 15, 2008: bsdcpio now seems to correctly write hardlinks into newc,
+	ustar, and old cpio archives.  Just a little more testing before
+	bsdcpio 1.0 becomes a reality.
+Mar 15, 2008: I think the new linkify() interface is finally handling
+	all known hardlink strategies.
+Mar 15, 2008: Mtree read fixes from Joerg Sonnenberger.
+Mar 15, 2008: Many new bsdtar and bsdcpio options from Joerg Sonnenberger.
+Mar 15, 2008: test harnesses no longer require uudecode; they
+	now have built-in decoding logic that decodes the reference
+	files as they are needed.
+
+Mar 14, 2008: libarchive 2.4.14 released; identical to 2.4.13 except for
+	a point fix for gname/uname mixup in pax format that was introduced
+	with the UTF-8 fixes.
+
+Feb 26, 2008: libarchive 2.4.13 released
+Feb 25, 2008: Handle path, linkname, gname, or uname that can't be converted
+	to/from UTF-8.  Implement "hdrcharset" attribute from SUS-2008.
+Feb 25, 2008: Fix name clash on NetBSD.
+Feb 18, 2008: Fix writing empty 'ar' archives, per Kai Wang
+Feb 18, 2008: [bsdtar] Permit appending on block devices.
+Feb 09, 2008: New "linkify" resolver to help with newc hardlink writing;
+	bsdcpio still needs to be converted to use this.
+Feb 02, 2008: Windows compatibility fixes from Ivailo Petrov, Kees Zeelenberg
+Jan 30, 2008: Ignore hardlink size for non-POSIX tar archives.
+
+Jan 22, 2008: libarchive 2.4.12 released
+Jan 22, 2008: Fix bad padding when writing symlinks to newc cpio archives.
+Jan 22, 2008: Verify bsdcpio_test by getting it to work against GNU cpio 2.9.
+	bsdcpio_test complains about missing options (-y and -z), format
+	of informational messages (--version, --help), and a minor formatting
+	issue in odc format output.  After this update, bsdcpio_test uncovered
+	several more cosmetic issues in bsdcpio, all now fixed.
+Jan 22, 2008: Experimental support for self-extracting Zip archives.
+Jan 22, 2008: Extend hardlink restore strategy to work correctly with
+	hardlinks extracted from newc cpio files.  (Which store the body
+	only with the last occurrence of a link.)

+	pattern selection for -i and -it.
+
+Dec 13, 2007: libarchive 2.4.8 released
+Dec 13, 2007: gzip and bzip2 compression now handle zero-byte writes correctly,

+Oct 30, 2007: libarchive 2.4.0 released
+Oct 30, 2007: Minor compile fix thanks to Joerg Schilling.
+Oct 30, 2007: Only run the format auction once at the beginning of the
+	archive.  This is simpler and supports better error recovery.
+Oct 29, 2007: Test support for very large entries in tar archives:
+	libarchive_test now exercises entries from 2GB up to 1TB.
+
+Oct 27, 2007: libarchive 2.3.5 released
+Oct 27, 2007: Correct some unnecessary internal data copying in the
+	"compression none" reader and writer; this reduces user time

+Oct 27, 2007: Fix for skipping archive entries that are exactly
+	a multiple of 4G on 32-bit platforms.
+Oct 25, 2007: Fix for reading very large (>8G) tar archives; this was
+	broken when I put in support for new GNU tar sparse formats.
+Oct 20, 2007: Initial work on new pattern-matching code for cpio; I
+	hope this eventually replaces the code currently in bsdtar.
+
+Oct 08, 2007: libarchive 2.3.4 released
+Oct 05, 2007: Continuing work on bsdcpio test suite.
+Oct 05, 2007: New cpio.5 manpage, updates to "History" of bsdcpio.1 and
+	bsdtar.1 manpages.
+Oct 05, 2007: Fix zip reader to immediately return EOF if you try
+	to read body of non-regular file.  In particular, this fixes
+	bsdtar extraction of zip archives.
+
+Sep 30, 2007: libarchive 2.3.3 released
+Sep 26, 2007: Rework Makefile.am so that the enable/disable options
+	actually do the right things.
+Sep 26, 2007: cpio-odc and cpio-newc archives no longer write bodies
+	for non-regular files.
+Sep 26, 2007: Test harness for bsdcpio is in place, needs more tests written.
+	This is much nicer than the ragtag collection of test scripts
+	that bsdtar has.
+
+Sep 20, 2007: libarchive 2.3.2 released
+Sep 20, 2007: libarchive 2.3.1 broke bsdtar because the archive_write_data()
+	fix was implemented incorrectly.
+
+Sep 16, 2007: libarchive 2.3.1 released
+Sep 16, 2007: Many fixes to bsdcpio 0.3:  handle hardlinks with -p, recognize
+	block size on writing, fix a couple of segfaults.
+Sep 16, 2007: Fixed return value from archive_write_data() when used
+	with archive_write_disk() to match the documentation and other
+	instances of this same function.
+Sep 15, 2007: Add archive_entry_link_resolver, archive_entry_strmode
+
+Sep 11, 2007: libarchive 2.2.8 released
+Sep 09, 2007: bsdcpio 0.2 supports most (not yet all) of the old POSIX spec.
+
+Sep 01, 2007: libarchive 2.2.7 released
+Aug 31, 2007: Support for reading mtree files, including an mtree.5 manpage
+	(A little experimental still.)
+Aug 18, 2007: Read gtar 1.17 --posix --sparse entries.
+Aug 13, 2007: Refined suid/sgid restore handling; it is no longer
+	an error if suid/sgid bits are dropped when you request
+	perm restore but don't request owner restore.
+Aug 06, 2007: Use --enable-bsdcpio if you want to try bsdcpio
+
+Aug 05, 2007: libarchive 2.2.6 released
+Aug 05, 2007: New configure option --disable-bsdtar, thanks to Joerg
+	Sonnenberger.
+Aug 05, 2007: Several bug fixes from FreeBSD CVS repo.
+
+Jul 13, 2007: libarchive 2.2.5 released
+
+Jul 12, 2007: libarchive 2.2.4 released
+Jul 12, 2007: Thanks to Colin Percival's help in diagnosing and
+	fixing several critical security bugs.  Details available at
+	http://security.freebsd.org/advisories/FreeBSD-SA-07:05.libarchive.asc
+
+May 26, 2007: libarchive 2.2.3 released
+May 26, 2007: Fix memory leaks in ZIP reader and shar writer, add some
+	missing system headers to archive_entry.h, dead code cleanup
+	from Colin Percival, more tests for gzip/bzip2, fix an
+	EOF anomaly in bzip2 decompression.
+
+May 12, 2007: libarchive 2.2.2 released
+May 12, 2007: Fix archive_write_disk permission restore by cloning
+	entry passed into write_header so that permission info is
+	still available at finish_entry time.  (archive_read_extract()
+	worked okay because it held onto the passed-in entry, but
+	direct consumers of archive_write_disk would break).  This
+	required fixing archive_entry_clone(), which now works and has
+	a reasonably complete test case.
+May 10, 2007: Skeletal cpio implementation.
+
+May 06, 2007: libarchive 2.2.1 released
+May 06, 2007: Flesh out a lot more of test_entry.c so as to catch
+	problems such as the device node breakage before releasing <sigh>.
+May 05, 2007: Fix a bad bug introduced in 2.1.9 that broke device
+	node entries in tar archives.
+May 03, 2007: Move 'struct stat' out of archive_entry core as well.
+	This removes some portability headaches and fixes a bunch
+	of corner cases that arise when manipulating archives on
+	dissimilar systems.
+
+Apr 30, 2007: libarchive 2.1.10 released
+Apr 31, 2007: Minor code cleanup.
+
+Apr 24, 2007: libarchive 2.1.9 released
+Apr 24, 2007: Fix some recently-introduced problems with libraries
+	(Just let automake handle it and it all works much better.)
+	Finish isolating major()/minor()/makedev() in archive_entry.c.
+
+Apr 23, 2007: libarchive 2.1.8 released
+Apr 23, 2007: Minor fixes found from building on MacOS X
+
+Apr 22, 2007: libarchive 2.1.7 released
+Apr 22, 2007: Eliminated all uses of 'struct stat' from the
+	format readers/writers.  This should improve portability;
+	'struct stat' is now only used in archive_entry and in
+	code that actually touches the disk.
+
+Apr 17, 2007: libarchive 2.1.6 released
+	Libarchive now compiles and passes all tests on Interix.
+
+Apr 16, 2007: libarchive 2.1.5 released
+
+Apr 15, 2007: libarchive 2.1b2 released
+Apr 15, 2007: New libarchive_internals.3 documentation of internal APIs.
+	Not complete, but should prove helpful.
+Apr 15, 2007: Experimental "read_compress_program" and "write_compress_program"
+	for using libarchive with external compression.  Not yet
+	well tested, and likely has portability issues.  Feedback
+	appreciated.
+
+Apr 14, 2007: libarchive 2.0.31 released
+Apr 14, 2007: More fixes for Interix, more 'ar' work
+
+Apr 14, 2007: libarchive 2.0.30 released
+Apr 13, 2007: libarchive now enforces trailing '/' on dirs
+	written to tar archives
+
+Apr 11, 2007: libarchive 2.0.29 released
+Apr 11, 2007: Make it easier to statically configure for different platforms.
+Apr 11, 2007: Updated config.guess, config.sub, libtool
+
+Apr 06, 2007: libarchive 2.0.28 released
+Apr 06, 2007: 'ar' format read/write support thanks to Kai Wang.
+
+Apr 01, 2007: libarchive 2.0.27 released
+Mar 31, 2007: Several minor fixes from Colin Percival and Joerg Sonnenberger.
+
+Mar 12, 2007: libarchive 2.0.25 released
+Mar 12, 2007: Fix broken --unlink flag.
+
+Mar 11, 2007: libarchive 2.0.24 released
+Mar 10, 2007: Correct an ACL blunder that causes any ACL with an entry
+    that refers to a non-existent user or group to not be restored correctly.
+    The fix both makes the parser more tolerant (so that archives created
+    with the buggy ACLs can be read now) and corrects the ACL formatter.
+Mar 10, 2007: More work on test portability to Linux.
+
+Mar 10, 2007: libarchive 2.0.22 released
+Mar 10, 2007: Header cleanups; added linux/fs.h, removed
+    some unnecessary headers, added #include guards in bsdtar.
+    If you see any obvious compile failures from this, let me know.
+Mar 10, 2007: Work on bsdtar test scripts: not yet robust enough
+    to enable as part of "make check", but getting better.
+Mar 10, 2007: libarchive now returns ARCHIVE_FAILED when
+    a header write fails in a way that only affects this item.
+    Less bad than ARCHIVE_FATAL, but worse than ARCHIVE_WARN.
+
+Mar 07, 2007: libarchive 2.0.21 released
+Mar 07, 2007: Add some ACL tests (only for the system-independent
+    portion of the ACL support for now).
+Mar 07, 2007: tar's ability to read ACLs off disk got
+    turned off for FreeBSD; re-enable it.  (ACL restores and
+    libarchive support for storing/reading ACLs from pax
+    archives was unaffected.)
+
+Mar 02, 2007: libarchive 2.0.20 released
+Mar 2, 2007:  It's not perfect, but it's pretty good.
+    Libarchive 2.0 is officially out of beta.
+
+Feb 28, 2007: libarchive 2.0b17 released
+Feb 27, 2007: Make the GID restore checks more robust by checking
+    whether the current user has too few or too many privileges.
+
+Feb 26, 2007: libarchive 2.0b15 released
+Feb 26, 2007: Don't lose symlinks when extracting from ISOs.
+    Thanks to Diego "Flameeyes" Pettenò for telling me about the
+    broken testcase on Gentoo that (finally!) led me to the cause
+    of this long-standing bug.
+
+Feb 26, 2007: libarchive 2.0b14 released
+Feb 26, 2007: Fix a broken test on platforms that lack lchmod().
+
+Feb 25, 2007: libarchive 2.0b13 released
+Feb 25, 2007: Empty archives were being written as empty files,
+    without a proper end-of-archive marker.  Fixed.
+
+Feb 23, 2007: libarchive 2.0b12 released
+Feb 22, 2007: Basic security checks added: _EXTRACT_SECURE_NODOTDOT
+    and _EXTRACT_SECURE_SYMLINK.  These checks used to be in bsdtar,
+    but they belong down in libarchive where they can be used by
+    other tools and where they can be better optimized.
+
+Feb 11, 2007: libarchive 2.0b11 released
+Feb 10, 2007: Fixed a bunch of errors in libarchive's handling
+    of EXTRACT_PERM and EXTRACT_OWNER, especially relating
+    to SUID and SGID bits.
+
+Jan 31, 2007: libarchive 2.0b9 released
+Jan 31, 2007: Added read support for "empty" archives as a
+    distinct archive format.  Bsdtar uses this to handle, e.g.,
+    "touch foo.tar; tar -rf foo.tar"
+
+Jan 22, 2007: libarchive 2.0b6 released
+Jan 22, 2007: archive_write_disk API is now in place.  It provides
+    a finer-grained interface than archive_read_extract.  In particular,
+    you can use it to create objects on disk without having an archive
+    around (just feed it archive_entry objects describing what you
+    want to create), you can override the uname/gname-to-uid/gid lookups
+    (minitar uses this to avoid getpwXXX() and getgrXXX() bloat).
+
+Jan 09, 2007: libarchive 2.0a3 released
+Jan 9, 2007: archive_extract is now much better; it handles the
+    most common cases with a minimal number of system calls.
+    Some features still need a lot of testing, especially corner
+    cases involving objects that already exist on disk.   I expect
+    the next round of API overhaul will simplify building test cases.
+Jan 9, 2007: a number of fixes thanks to Colin Percival, especially
+    corrections to the skip() framework and handling of large files.
+Jan 9, 2007: Fixes for large ISOs.  The code should correctly handle
+    very large ISOs with entries up to 4G.   Thanks to Robert Sciuk
+    for pointing out these issues.
+
+Sep 05, 2006: libarchive 1.3.1 released
+Sep 5, 2006: Bump version to 1.3 for new I/O wrappers.
+Sep 4, 2006: New memory and FILE read/write wrappers.
+Sep 4, 2006: libarchive test harness is now minimally functional;
+    it's located a few minor bugs in error-handling logic
+
+Aug 17, 2006: libarchive 1.2.54 released
+Aug 17, 2006: Outline ABI changes for libarchive 2.0; these
+   are protected behind #ifdef's until I think I've found everything
+   that needs to change.
+Aug 17, 2006: Fix error-handling in archive_read/write_close()
+   They weren't returning any errors before.
+Aug 17, 2006: Fix recursive-add logic to not trigger if it's not set
+   Fixes a bug adding files when writing archive to pipe or when
+   using archive_write_open() directly.
+Jul 2006: New "skip" handling improves performance extracting
+   single files from large uncompressed archives.
+
+Mar 21, 2006: 1.2.52 released
+Mar 21, 2006: Fix -p on platforms that don't have platform-specific
+   extended attribute code.
+Mar 20, 2006: Add NEWS file; fill in some older history from other
+   files.  I'll try to keep this file up-to-date from now on.
+
+OLDER NEWS SUMMARIES
+
+Mar 19, 2006: libarchive 1.2.51 released
+Mar 18, 2006: Many fixes to extended attribute support, including a redesign
+   of the storage format to simplify debugging.
+Mar 12, 2006: Remove 'tp' support; it was a fun idea, but not worth
+   spending much time on.
+Mar 11, 2006: Incorporated Jaakko Heinonen's still-experimental support
+   for extended attributes (Currently Linux-only.).
+Mar 11, 2006: Reorganized distribution package: There is now one tar.gz
+   file that builds both libarchive and bsdtar.
+Feb 13, 2006: Minor bug fixes: correctly read cpio device entries, write
+   Pax attribute entry names.
+Nov 7, 2005: Experimental 'tp' format support in libarchive.  Feedback
+   appreciated; this is not enabled by archive_read_support_format_all()
+   yet as I'm not quite content with the format detection heuristics.
+Nov 7, 2005: Some more portability improvements thanks to Darin Broady,
+   minor bugfixes.
+Oct 12, 2005: Use GNU libtool to build shared libraries on many systems.
+Aug 9, 2005: Correctly detect that MacOS X does not have POSIX ACLs.
+Apr 17, 2005: Kees Zeelenberg has ported libarchive and bsdtar to Windows:
+   http://gnuwin32.sourceforge.net/
+Apr 11, 2005: Extended Zip/Zip64 support thanks to Dan Nelson.  -L/-h
+   fix from Jaakko Heinonen.
+Mar 12, 2005: archive_read_extract can now handle very long
+   pathnames (I've tested with pathnames up to 1MB).
+Mar 12, 2005: Marcus Geiger has written an article about libarchive
+   http://xsnil.antbear.org/2005/02/05/archive-mit-libarchive-verarbeiten/
+   including examples of using it from Objective-C.  His MoinX
+   http://moinx.antbear.org/ desktop Wiki uses
+   libarchive for archiving and restoring Wiki pages.
+Jan 22, 2005: Preliminary ZIP extraction support,
+    new directory-walking code for bsdtar.
+Jan 16, 2005: ISO9660 extraction code added; manpage corrections.
+May 22, 2004: Many gtar-compatible long options have been added; almost
+    all FreeBSD ports extract correctly with bsdtar.
+May 18, 2004: bsdtar can read Solaris, HP-UX, Unixware, star, gtar,
+    and pdtar archives.

+# Welcome to libarchive!
+
+The libarchive project develops a portable, efficient C library that
+can read and write streaming archives in a variety of formats.  It
+also includes implementations of the common `tar`, `cpio`, and `zcat`
+command-line tools that use the libarchive library.
+
+## Questions?  Issues?
+
+* https://www.libarchive.org is the home for ongoing
+  libarchive development, including documentation,
+  and links to the libarchive mailing lists.
+* To report an issue, use the issue tracker at
+  https://github.com/libarchive/libarchive/issues
+* To submit an enhancement to libarchive, please
+  submit a pull request via GitHub: https://github.com/libarchive/libarchive/pulls
+
+## Contents of the Distribution
+
+This distribution bundle includes the following major components:
+
+* **libarchive**: a library for reading and writing streaming archives
+* **tar**: the 'bsdtar' program is a full-featured 'tar' implementation built on libarchive
+* **cpio**: the 'bsdcpio' program is a different interface to essentially the same functionality
+* **cat**: the 'bsdcat' program is a simple replacement tool for zcat, bzcat, xzcat, and such
+* **unzip**: the 'bsdunzip' program is a simple replacement tool for Info-ZIP's unzip
+* **examples**: Some small example programs that you may find useful.
+* **examples/minitar**: a compact sample demonstrating use of libarchive.
+* **contrib**:  Various items sent to me by third parties; please contact the authors with any questions.
+
+The top-level directory contains the following information files:
+
+* **NEWS** - highlights of recent changes
+* **COPYING** - what you can do with this
+* **INSTALL** - installation instructions
+* **README** - this file
+* **CMakeLists.txt** - input for "cmake" build tool, see INSTALL
+* **configure** - configuration script, see INSTALL for details.  If your copy of the source lacks a `configure` script, you can try to construct it by running the script in `build/autogen.sh` (or use `cmake`).
+
+The following files in the top-level directory are used by the 'configure' script:
+
+* `Makefile.am`, `aclocal.m4`, `configure.ac` - used to build this distribution, only needed by maintainers
+* `Makefile.in`, `config.h.in` - templates used by configure script
+
+## Documentation
+
+In addition to the informational articles and documentation
+in the online [libarchive Wiki](https://github.com/libarchive/libarchive/wiki),
+the distribution also includes a number of manual pages:
+
+ * bsdtar.1 explains the use of the bsdtar program
+ * bsdcpio.1 explains the use of the bsdcpio program
+ * bsdcat.1 explains the use of the bsdcat program
+ * libarchive.3 gives an overview of the library as a whole
+ * archive_read.3, archive_write.3, archive_write_disk.3, and
+   archive_read_disk.3 provide detailed calling sequences for the read
+   and write APIs
+ * archive_entry.3 details the "struct archive_entry" utility class
+ * archive_internals.3 provides some insight into libarchive's
+   internal structure and operation.
+ * libarchive-formats.5 documents the file formats supported by the library
+ * cpio.5, mtree.5, and tar.5 provide detailed information about these
+   popular archive formats, including hard-to-find details about
+   modern cpio and tar variants.
+
+The manual pages above are provided in the 'doc' directory in
+a number of different formats.
+
+You should also read the copious comments in `archive.h` and the
+source code for the sample programs for more details.  Please let us
+know about any errors or omissions you find.
+
+## Supported Formats
+
+Currently, the library automatically detects and reads the following formats:
+
+  * Old V7 tar archives
+  * POSIX ustar
+  * GNU tar format (including GNU long filenames, long link names, and sparse files)
+  * Solaris 9 extended tar format (including ACLs)
+  * POSIX pax interchange format
+  * POSIX octet-oriented cpio
+  * SVR4 ASCII cpio
+  * Binary cpio (big-endian or little-endian)
+  * PWB binary cpio
+  * ISO9660 CD-ROM images (with optional Rockridge or Joliet extensions)
+  * ZIP archives (with uncompressed or "deflate" compressed entries, including support for encrypted Zip archives)
+  * ZIPX archives (with support for bzip2, ppmd8, lzma and xz compressed entries)
+  * GNU and BSD 'ar' archives
+  * 'mtree' format
+  * 7-Zip archives (including archives that use zstandard compression)
+  * Microsoft CAB format
+  * LHA and LZH archives
+  * RAR and RAR 5.0 archives (with some limitations due to RAR's proprietary status)
+  * XAR archives
+
+The library also detects and handles any of the following before evaluating the archive:
+
+  * uuencoded files
+  * files with RPM wrapper
+  * gzip compression
+  * bzip2 compression
+  * compress/LZW compression
+  * lzma, lzip, and xz compression
+  * lz4 compression
+  * lzop compression
+  * zstandard compression
+
+The library can create archives in any of the following formats:
+
+  * POSIX ustar
+  * POSIX pax interchange format
+  * "restricted" pax format, which will create ustar archives except for
+    entries that require pax extensions (for long filenames, ACLs, etc).
+  * Old GNU tar format
+  * Old V7 tar format
+  * POSIX octet-oriented cpio
+  * SVR4 "newc" cpio
+  * Binary cpio (little-endian)
+  * PWB binary cpio
+  * shar archives
+  * ZIP archives (with uncompressed or "deflate" compressed entries)
+  * GNU and BSD 'ar' archives
+  * 'mtree' format
+  * ISO9660 format
+  * 7-Zip archives
+  * XAR archives
+
+When creating archives, the result can be filtered with any of the following:
+
+  * uuencode
+  * gzip compression
+  * bzip2 compression
+  * compress/LZW compression
+  * lzma, lzip, and xz compression
+  * lz4 compression
+  * lzop compression
+  * zstandard compression
+
+## Notes about the Library Design
+
+The following notes address many of the most common
+questions we are asked about libarchive:
+
+* This is a heavily stream-oriented system.  That means that
+  it is optimized to read or write the archive in a single
+  pass from beginning to end.  For example, this allows
+  libarchive to process archives too large to store on disk
+  by processing them on-the-fly as they are read from or
+  written to a network or tape drive.  This also makes
+  libarchive useful for tools that need to produce
+  archives on-the-fly (such as webservers that provide
+  archived contents of a users account).
+
+* In-place modification and random access to the contents
+  of an archive are not directly supported.  For some formats,
+  this is not an issue: For example, tar.gz archives are not
+  designed for random access.  In some other cases, libarchive
+  can re-open an archive and scan it from the beginning quickly
+  enough to provide the needed abilities even without true
+  random access.  Of course, some applications do require true
+  random access; those applications should consider alternatives
+  to libarchive.
+
+* The library is designed to be extended with new compression and
+  archive formats.  The only requirement is that the format be
+  readable or writable as a stream and that each archive entry be
+  independent.  There are articles on the libarchive Wiki explaining
+  how to extend libarchive.
+
+* On read, compression and format are always detected automatically.
+
+* The same API is used for all formats; it should be very
+  easy for software using libarchive to transparently handle
+  any of libarchive's archiving formats.
+
+* Libarchive's automatic support for decompression can be used
+  without archiving by explicitly selecting the "raw" and "empty"
+  formats.
+
+* I've attempted to minimize static link pollution.  If you don't
+  explicitly invoke a particular feature (such as support for a
+  particular compression or format), it won't get pulled in to
+  statically-linked programs.  In particular, if you don't explicitly
+  enable a particular compression or decompression support, you won't
+  need to link against the corresponding compression or decompression
+  libraries.  This also reduces the size of statically-linked
+  binaries in environments where that matters.
+
+* The library is generally _thread safe_ depending on the platform:
+  it does not define any global variables of its own.  However, some
+  platforms do not provide fully thread-safe versions of key C library
+  functions.  On those platforms, libarchive will use the non-thread-safe
+  functions.  Patches to improve this are of great interest to us.
+
+* The function `archive_write_disk_header()` is _not_ thread safe on
+  POSIX machines and could lead to security issue resulting in world
+  writeable directories.  Thus it must be mutexed by the calling code.
+  This is due to calling `umask(oldumask = umask(0))`, which sets the
+  umask for the whole process to 0 for a short time frame.
+  In case other thread calls the same function in parallel, it might
+  get interrupted by it and cause the executable to use umask=0 for the
+  remaining execution.
+  This will then lead to implicitely created directories to have 777
+  permissions without sticky bit.
+
+* In particular, libarchive's modules to read or write a directory
+  tree do use `chdir()` to optimize the directory traversals.  This
+  can cause problems for programs that expect to do disk access from
+  multiple threads.  Of course, those modules are completely
+  optional and you can use the rest of libarchive without them.
+
+* The library is _not_ thread aware, however.  It does no locking
+  or thread management of any kind.  If you create a libarchive
+  object and need to access it from multiple threads, you will
+  need to provide your own locking.
+
+* On read, the library accepts whatever blocks you hand it.
+  Your read callback is free to pass the library a byte at a time
+  or mmap the entire archive and give it to the library at once.
+  On write, the library always produces correctly-blocked output.
+
+* The object-style approach allows you to have multiple archive streams
+  open at once.  bsdtar uses this in its "@archive" extension.
+
+* The archive itself is read/written using callback functions.
+  You can read an archive directly from an in-memory buffer or
+  write it to a socket, if you wish.  There are some utility
+  functions to provide easy-to-use "open file," etc, capabilities.
+
+* The read/write APIs are designed to allow individual entries
+  to be read or written to any data source:  You can create
+  a block of data in memory and add it to a tar archive without
+  first writing a temporary file.  You can also read an entry from
+  an archive and write the data directly to a socket.  If you want
+  to read/write entries to disk, there are convenience functions to
+  make this especially easy.
+
+* Note: The "pax interchange format" is a POSIX standard extended tar
+  format that should be used when the older _ustar_ format is not
+  appropriate.  It has many advantages over other tar formats
+  (including the legacy GNU tar format) and is widely supported by
+  current tar implementations.

+ * Utility to match up hardlinks.
+ *
+ * The 'struct archive_entry_linkresolver' is a cache of archive entries
+ * for files with multiple links.  Here's how to use it:
+ *   1. Create a lookup object with archive_entry_linkresolver_new()
+ *   2. Tell it the archive format you're using.
+ *   3. Hand each archive_entry to archive_entry_linkify().
+ *      That function will return 0, 1, or 2 entries that should
+ *      be written.
+ *   4. Call archive_entry_linkify(resolver, NULL) until
+ *      no more entries are returned.
+ *   5. Call archive_entry_linkresolver_free(resolver) to free resources.
+ *
+ * The entries returned have their hardlink and size fields updated
+ * appropriately.  If an entry is passed in that does not refer to
+ * a file with multiple links, it is returned unchanged.  The intention
+ * is that you should be able to simply filter all entries through
+ * this machine.
+ *
+ * To make things more efficient, be sure that each entry has a valid
+ * nlinks value.  The hardlink cache uses this to track when all links
+ * have been found.  If the nlinks value is zero, it will keep every
+ * name in the cache indefinitely, which can use a lot of memory.
+ *
+ * Note that archive_entry_size() is reset to zero if the file
+ * body should not be written to the archive.  Pay attention!
+ */
+struct archive_entry_linkresolver;
+
+/*
+ * There are three different strategies for marking hardlinks.
+ * The descriptions below name them after the best-known
+ * formats that rely on each strategy:
+ *
+ * "Old cpio" is the simplest, it always returns any entry unmodified.
+ *    As far as I know, only cpio formats use this.  Old cpio archives
+ *    store every link with the full body; the onus is on the dearchiver
+ *    to detect and properly link the files as they are restored.
+ * "tar" is also pretty simple; it caches a copy the first time it sees
+ *    any link.  Subsequent appearances are modified to be hardlink
+ *    references to the first one without any body.  Used by all tar
+ *    formats, although the newest tar formats permit the "old cpio" strategy
+ *    as well.  This strategy is very simple for the dearchiver,
+ *    and reasonably straightforward for the archiver.
+ * "new cpio" is trickier.  It stores the body only with the last
+ *    occurrence.  The complication is that we might not
+ *    see every link to a particular file in a single session, so
+ *    there's no easy way to know when we've seen the last occurrence.
+ *    The solution here is to queue one link until we see the next.
+ *    At the end of the session, you can enumerate any remaining
+ *    entries by calling archive_entry_linkify(NULL) and store those
+ *    bodies.  If you have a file with three links l1, l2, and l3,
+ *    you'll get the following behavior if you see all three links:
+ *           linkify(l1) => NULL   (the resolver stores l1 internally)
+ *           linkify(l2) => l1     (resolver stores l2, you write l1)
+ *           linkify(l3) => l2, l3 (all links seen, you can write both).
+ *    If you only see l1 and l2, you'll get this behavior:
+ *           linkify(l1) => NULL
+ *           linkify(l2) => l1
+ *           linkify(NULL) => l2   (at end, you retrieve remaining links)
+ *    As the name suggests, this strategy is used by newer cpio variants.
+ *    It's noticeably more complex for the archiver, slightly more complex
+ *    for the dearchiver than the tar strategy, but makes it straightforward
+ *    to restore a file using any link by simply continuing to scan until
+ *    you see a link that is stored with a body.  In contrast, the tar
+ *    strategy requires you to rescan the archive from the beginning to
+ *    correctly extract an arbitrary link.

+ * The next section implements the peek/consume internal I/O
+ * system used by archive readers.  This system allows simple
+ * read-ahead for consumers while preserving zero-copy operation
+ * most of the time.
+ *
+ * The two key operations:
+ *  * The read-ahead function returns a pointer to a block of data
+ *    that satisfies a minimum request.
+ *  * The consume function advances the file pointer.
+ *
+ * In the ideal case, filters generate blocks of data
+ * and __archive_read_ahead() just returns pointers directly into
+ * those blocks.  Then __archive_read_consume() just bumps those
+ * pointers.  Only if your request would span blocks does the I/O
+ * layer use a copy buffer to provide you with a contiguous block of
+ * data.
+ *
+ * A couple of useful idioms:
+ *  * "I just want some data."  Ask for 1 byte and pay attention to
+ *    the "number of bytes available" from __archive_read_ahead().
+ *    Consume whatever you actually use.
+ *  * "I want to output a large block of data."  As above, ask for 1 byte,
+ *    emit all that's available (up to whatever limit you have), consume
+ *    it all, then repeat until you're done.  This effectively means that
+ *    you're passing along the blocks that came from your provider.
+ *  * "I want to peek ahead by a large amount."  Ask for 4k or so, then
+ *    double and repeat until you get an error or have enough.  Note
+ *    that the I/O layer will likely end up expanding its copy buffer
+ *    to fit your request, so use this technique cautiously.  This
+ *    technique is used, for example, by some of the format tasting
+ *    code that has uncertain look-ahead needs.
+ */

+/*
+ * Looks ahead in the input stream:
+ *  * If 'avail' pointer is provided, that returns number of bytes available
+ *    in the current buffer, which may be much larger than requested.
+ *  * If end-of-file, *avail gets set to zero.
+ *  * If error, *avail gets error code.
+ *  * If request can be met, returns pointer to data.
+ *  * If minimum request cannot be met, returns NULL.
+ *
+ * Note: If you just want "some data", ask for 1 byte and pay attention
+ * to *avail, which will have the actual amount available.  If you
+ * know exactly how many bytes you need, just ask for that and treat
+ * a NULL return as an error.

+ * an opaque interface (easier to modify in the future).
+ *
+ * Internally, it keeps a single list of "tree_entry" items that
+ * represent filesystem objects that require further attention.
+ * Non-directories are not kept in memory: they are pulled from
+ * readdir(), returned to the client, then freed as soon as possible.
+ * Any directory entry to be traversed gets pushed onto the stack.
+ *
+ * There is surprisingly little information that needs to be kept for
+ * each item on the stack.  Just the name, depth (represented here as the
+ * string length of the parent directory's pathname), and some markers
+ * indicating how to get back to the parent (via chdir("..") for a
+ * regular dir or via fchdir(2) for a symlink).

+ * An overview of ISO 9660 format:
+ *
+ * Each disk is laid out as follows:
+ *   * 32k reserved for private use
+ *   * Volume descriptor table.  Each volume descriptor
+ *     is 2k and specifies basic format information.
+ *     The "Primary Volume Descriptor" (PVD) is defined by the
+ *     standard and should always be present; other volume
+ *     descriptors include various vendor-specific extensions.
+ *   * Files and directories.  Each file/dir is specified by
+ *     an "extent" (starting sector and length in bytes).
+ *     Dirs are just files with directory records packed one
+ *     after another.  The PVD contains a single dir entry
+ *     specifying the location of the root directory.  Everything
+ *     else follows from there.
+ *
+ * This module works by first reading the volume descriptors, then
+ * building a list of directory entries, sorted by starting
+ * sector.  At each step, I look for the earliest dir entry that
+ * hasn't yet been read, seek forward to that location and read
+ * that entry.  If it's a dir, I slurp in the new dir entries and
+ * add them to the heap; if it's a regular file, I return the
+ * corresponding archive_entry and wait for the client to request
+ * the file body.  This strategy allows us to read most compliant
+ * CDs with a single pass through the data, as required by libarchive.

+ * From the birds-eye view a RAR file looks file this:
+ *
+ * <magic><base_block_1><base_block_2>...<base_block_n>
+ *
+ * There are a few types of base blocks. Those types are specified inside
+ * the 'switch' statement in this function. For example purposes, I'll write
+ * how a standard RARv5 file could look like here:
+ *
+ * <magic><MAIN><FILE><FILE><FILE><SERVICE><ENDARC>
+ *
+ * The structure above could describe an archive file with 3 files in it,
+ * one service "QuickOpen" block (that is ignored by this parser), and an
+ * end of file base block marker.
+ *
+ * If the file is stored in multiple archive files ("multiarchive"), it might
+ * look like this:
+ *
+ * .part01.rar: <magic><MAIN><FILE><ENDARC>
+ * .part02.rar: <magic><MAIN><FILE><ENDARC>
+ * .part03.rar: <magic><MAIN><FILE><ENDARC>
+ *
+ * This example could describe 3 RAR files that contain ONE archived file.
+ * Or it could describe 3 RAR files that contain 3 different files. Or 3
+ * RAR files than contain 2 files. It all depends what metadata is stored in
+ * the headers of <FILE> blocks.
+ *
+ * Each <FILE> block contains info about its size, the name of the file it's
+ * storing inside, and whether this FILE block is a continuation block of
+ * previous archive ('split before'), and is this FILE block should be
+ * continued in another archive ('split after'). By parsing the 'split before'
+ * and 'split after' flags, we're able to tell if multiple <FILE> base blocks
+ * are describing one file, or multiple files (with the same filename, for
+ * example).
+ *
+ * One thing to note is that if we're parsing the first <FILE> block, and
+ * we see 'split after' flag, then we need to jump over to another <FILE>
+ * block to be able to decompress rest of the data. To do this, we need
+ * to skip the <ENDARC> block, then switch to another file, then skip the
+ * <magic> block, <MAIN> block, and then we're standing on the proper
+ * <FILE> block.

+/**
+ * WARC is standardised by ISO TC46/SC4/WG12 and currently available as
+ * ISO 28500:2009.
+ * For the purposes of this file we used the final draft from:
+ * http://bibnum.bnf.fr/warc/WARC_ISO_28500_version1_latestdraft.pdf
+ *
+ * Todo:
+ * [ ] real-world warcs can contain resources at endpoints ending in /
+ *     e.g. http://bibnum.bnf.fr/warc/
+ *     if you're lucky their response contains a Content-Location: header
+ *     pointing to a unix-compliant filename, in the example above it's
+ *     Content-Location: http://bibnum.bnf.fr/warc/index.html
+ *     however, that's not mandated and github for example doesn't follow
+ *     this convention.
+ *     We need a set of archive options to control what to do with
+ *     entries like these, at the moment care is taken to skip them.

+ * A set of compatibility glue for building libarchive on Windows platforms.
+ *
+ * Originally created as "libarchive-nonposix.c" by Kees Zeelenberg
+ * for the GnuWin32 project, trimmed significantly by Tim Kientzle.
+ *
+ * Much of the original file was unnecessary for libarchive, because
+ * many of the features it emulated were not strictly necessary for
+ * libarchive.  I hope for this to shrink further as libarchive
+ * internals are gradually reworked to sit more naturally on both
+ * POSIX and Windows.  Any ideas for this are greatly appreciated.
+ *
+ * The biggest remaining issue is the dev/ino emulation; libarchive
+ * has a couple of public APIs that rely on dev/ino uniquely
+ * identifying a file.  This doesn't match well with Windows.  I'm
+ * considering alternative APIs.

+ *   * Mac OS extended metadata includes ACLs, so must be deferred on dirs.

+Change Log for PCRE2 - see also the Git log
+-------------------------------------------
+
+
+Version 10.42 11-December-2022
+------------------------------
+
+1. Change 19 of 10.41 wasn't quite right; it put the definition of a default,
+empty value for PCRE2_CALL_CONVENTION in src/pcre2posix.c instead of
+src/pcre2posix.h, which meant that programs that included pcre2posix.h but not
+pcre2.h failed to compile.
+
+2. To catch similar issues to the above in future, a new small test program
+that includes pcre2posix.h but not pcre2.h has been added to the test suite.
+
+3. When the -S option of pcre2test was used to set a stack size greater than
+the allowed maximum, the error message displayed the hard limit incorrectly.
+This was pointed out on GitHub pull request #171, but the suggested patch
+didn't cope with all cases. Some further modification was required.
+
+4. Supplying an ovector count of more than 65535 to pcre2_match_data_create()
+caused a crash because the field in the match data block is only 16 bits. A
+maximum of 65535 is now silently applied.
+
+5. Merged @carenas patch #175 which fixes #86 - segfault on aarch64 (ARM),
+
+
+Version 10.41 06-December-2022
+------------------------------
+
+1. Add fflush() before and after a fork callout in pcre2grep to get its output
+to be the same on all systems. (There were previously ordering differences in
+Alpine Linux).
+
+2. Merged patch from @carenas (GitHub #110) for pthreads support in CMake.
+
+3. SSF scorecards grumbled about possible overflow in an expression in
+pcre2test. It never would have overflowed in practice, but some casts have been
+added and at the some time there's been some tidying of fprints that output
+size_t values.
+
+4. PR #94 showed up an unused enum in pcre2_convert.c, which is now removed.
+
+5. Minor code re-arrangement to remove gcc warning about realloc() in
+pcre2test.
+
+6. Change a number of int variables that hold buffer and line lengths in
+pcre2grep to PCRE2_SIZE (aka size_t).
+
+7. Added an #ifdef to cut out a call to PRIV(jit_free) when JIT is not
+supported (even though that function would do nothing in that case) at the
+request of a user who doesn't even want to link with pcre_jit_compile.o. Also
+tidied up an untidy #ifdef arrangement in pcre2test.
+
+8. Fixed an issue in the backtracking optimization of character repeats in
+JIT. Furthermore optimize star repetitions, not just plus repetitions.
+
+9. Removed the use of an initial backtracking frames vector on the system stack
+in pcre2_match() so that it now always uses the heap. (In a multi-thread
+environment with very small stacks there had been an issue.) This also is
+tidier for JIT matching, which didn't need that vector. The heap vector is now
+remembered in the match data block and re-used if that block itself is re-used.
+It is freed with the match data block.
+
+10. Adjusted the find_limits code in pcre2test to work with change 9 above.
+
+11. Added find_limits_noheap to pcre2test, because the heap limits are now
+different in different environments and so cannot be included in the standard
+tests.
+
+12. Created a test for pcre2_match() heap processing that is not part of the
+tests run by 'make check', but can be run manually. The current output is from
+a 64-bit system.
+
+13. Implemented -Z aka --null in pcre2grep.
+
+14. A minor change to pcre2test and the addition of several new pcre2grep tests
+have improved LCOV coverage statistics. At the same time, code in pcre2grep and
+elsewhere that can never be obeyed in normal testing has been excluded from
+coverage.
+
+15. Fixed a bug in pcre2grep that could cause an extra newline to be written
+after output generaed by --output.
+
+16. If a file has a .bz2 extension but is not in fact compressed, pcre2grep
+should process it as a plain text file. A bug stopped this happening; now fixed
+and added to the tests.
+
+17. When pcre2grep was running not in UTF mode, if a string specified by
+--output or obtained from a callout in a pattern contained a character (byte)
+greater than 127, it was incorrectly output in UTF-8 format.
+
+18. Added some casts after warnings from Clang sanitize.
+
+19. Merged patch from cbouc (GitHub #139): 4 function prototypes were missing
+PCRE2_CALL_CONVENTION in src/pcre2posix.h. All function prototypes returning
+pointers had out of place PCRE2_CALL_CONVENTION in src/pcre2.h.*. These
+produced errors when building for Windows with #define PCRE2_CALL_CONVENTION
+__stdcall.
+
+20. A negative repeat value in a pcre2test subject line was not being
+diagnosed, leading to infinite looping.
+
+21. Updated RunGrepTest to discard the warning that Bash now gives when setting
+LC_CTYPE to a bad value (because older versions didn't).
+
+22. Updated pcre2grep so that it behaves like GNU grep when matching more than
+one pattern and a later pattern matches at an earlier point in the subject when
+the matched substrings are being identified by colour or by offsets.
+
+23. Updated the PrepareRelease script so that the man page that it makes for
+the pcre2demo demonstration program is more standard and does not cause errors
+when processed by lexgrog or mandb -c (GitHub issue #160).
+
+24. The JIT compiler was updated.
+
+
+Version 10.40 15-April-2022
+---------------------------
+
+1. Merged patch from @carenas (GitHub #35, 7db87842) to fix pcre2grep incorrect
+handling of multiple passes.
+
+2. Merged patch from @carenas (GitHub #36, dae47509) to fix portability issue
+in pcre2grep with buffered fseek(stdin).
+
+3. Merged patch from @carenas (GitHub #37, acc520924) to fix tests when -S is
+not supported.
+
+4. Revert an unintended change in JIT repeat detection.
+
+5. Merged patch from @carenas (GitHub #52, b037bfa1) to fix build on GNU Hurd.
+
+6. Merged documentation and comments patches from @carenas (GitHub #47).
+
+7. Merged patch from @carenas (GitHub #49) to remove obsolete JFriedl test code
+from pcre2grep.
+
+8. Merged patch from @carenas (GitHub #48) to fix CMake install issue #46.
+
+9. Merged patch from @carenas (GitHub #53) fixing NULL checks in matching and
+substituting.
+
+10. Add null_subject and null_replacement modifiers to pcre2test.
+
+11. Add check for NULL subject to POSIX regexec() function.
+
+12. Add check for NULL replacement to pcre2_substitute().
+
+13. For the subject arguments of pcre2_match(), pcre2_dfa_match(), and
+pcre2_substitute(), and the replacement argument of the latter, if the pointer
+is NULL and the length is zero, treat as an empty string. Apparently a number
+of applications treat NULL/0 in this way.
+
+14. Added support for Bidi_Class and a number of binary Unicode properties,
+including Bidi_Control.
+
+15. Fix some minor issues raised by clang sanitize.
+
+16. Very minor code speed up for maximizing character property matches.
+
+17. A number of changes to script matching for \p and \P:
+
+    (a) Script extensions for a character are now coded as a bitmap instead of
+        a list of script numbers, which should be faster and does not need a
+        loop.
+
+    (b) Added the syntax \p{script:xxx} and \p{script_extensions:xxx} (synonyms
+        sc and scx).
+
+    (c) Changed \p{scriptname} from being the same as \p{sc:scriptname} to being
+        the same as \p{scx:scriptname} because this change happened in Perl at
+        release 5.26.
+
+    (d) The standard Unicode 4-letter abbreviations for script names are now
+        recognized.
+
+    (e) In accordance with Unicode and Perl's "loose matching" rules, spaces,
+        hyphens, and underscores are ignored in property names, which are then
+        matched independent of case.
+
+18. The Python scripts in the maint directory have been refactored. There are
+now three scripts that generate pcre2_ucd.c, pcre2_ucp.h, and pcre2_ucptables.c
+(which is #included by pcre2_tables.c). The data lists that used to be
+duplicated are now held in a single common Python module.
+
+19. On CHERI, and thus Arm's Morello prototype, pointers are represented as
+hardware capabilities, which consist of both an integer address and additional
+metadata, meaning they are twice the size of the platform's size_t type, i.e.
+16 bytes on a 64-bit system. The ovector member of heapframe happens to only be
+8 byte aligned, and so computing frame_size ended up with a multiple of 8 but
+not 16. Whilst the first frame was always suitably aligned, this then
+misaligned the frame that follows, resulting in an alignment fault when storing
+a pointer to Fecode at the start of match. Patch to fix this issue by Jessica
+Clarke PR#72.
+
+20. Added -LP and -LS listing options to pcre2test.
+
+21. A user discovered that the library names in CMakeLists.txt for MSVC
+debugger (PDB) files were incorrect - perhaps never tried for PCRE2?
+
+22. An item such as [Aa] is optimized into a caseless single character match.
+When this was quantified (e.g. [Aa]{2}) and was also the last literal item in a
+pattern, the optimizing "must be present for a match" character check was not
+being flagged as caseless, causing some matches that should have succeeded to
+fail.
+
+23. Fixed a unicode property matching issue in JIT. The character was not
+fully read in caseless matching.
+
+24. Fixed an issue affecting recursions in JIT caused by duplicated data
+transfers.
+
+25. Merged patch from @carenas (GitHub #96) which fixes some problems with
+pcre2test and readline/readedit:
+
+  * Use the right header for libedit in FreeBSD with autoconf
+  * Really allow libedit with cmake
+  * Avoid using readline headers with libedit
+
+
+Version 10.39 29-October-2021
+-----------------------------
+
+1. Fix incorrect detection of alternatives in first character search in JIT.
+
+2. Merged patch from @carenas (GitHub #28):
+
+  Visual Studio 2013 includes support for %zu and %td, so let newer
+  versions of it avoid the fallback, and while at it, make sure that
+  the first check is for DISABLE_PERCENT_ZT so it will be always
+  honoured if chosen.
+
+  prtdiff_t is signed, so use a signed type instead, and make sure
+  that an appropriate width is chosen if pointers are 64bit wide and
+  long is not (ex: Windows 64bit).
+
+  IMHO removing the cast (and therefore the possibilty of truncation)
+  make the code cleaner and the fallback is likely portable enough
+  with all 64-bit POSIX systems doing LP64 except for Windows.
+
+3. Merged patch from @carenas (GitHub #29) to update to Unicode 14.0.0.
+
+4. Merged patch from @carenas (GitHub #30):
+
+  * Cleanup: remove references to no longer used stdint.h
+
+  Since 19c50b9d (Unconditionally use inttypes.h instead of trying for stdint.h
+  (simplification) and remove the now unnecessary inclusion in
+  pcre2_internal.h., 2018-11-14), stdint.h is no longer used.
+
+  Remove checks for it in autotools and CMake and document better the expected
+  build failures for systems that might have stdint.h (C99) and not inttypes.h
+  (from POSIX), like old Windows.
+
+  * Cleanup: remove detection for inttypes.h which is a hard dependency
+
+  CMake checks for standard headers are not meant to be used for hard
+  dependencies, so will prevent a possible fallback to work.
+
+  Alternatively, the header could be checked to make the configuration fail
+  instead of breaking the build, but that was punted, as it was missing anyway
+  from autotools.
+
+5. Merged patch from @carenas (GitHub #32):
+
+  * jit: allow building with ancient MSVC versions
+
+  Visual Studio older than 2013 fails to build with JIT enabled, because it is
+  unable to parse non C89 compatible syntax, with mixed declarations and code.
+  While most recent compilers wouldn't even report this as a warning since it
+  is valid C99, it could be also made visible by adding to gcc/clang the
+  -Wdeclaration-after-statement flag at build time.
+
+  Move the code below the affected definitions.
+
+  * pcre2grep: avoid mixing declarations with code
+
+  Since d5a61ee8 (Patch to detect (and ignore) symlink loops in pcre2grep,
+  2021-08-28), code will fail to build in a strict C89 compiler.
+
+  Reformat slightly to make it C89 compatible again.
+
+
+Version 10.38 01-October-2021
+-----------------------------
+
+1. Fix invalid single character repetition issues in JIT when the repetition
+is inside a capturing bracket and the bracket is preceded by character
+literals.
+
+2. Installed revised CMake configuration files provided by Jan-Willem Blokland.
+This extends the CMake build system to build both static and shared libraries
+in one go, builds the static library with PIC, and exposes PCRE2 libraries
+using the CMake config files. JWB provided these notes:
+
+- Introduced CMake variable BUILD_STATIC_LIBS to build the static library.
+
+- Make a small modification to config-cmake.h.in by removing the PCRE2_STATIC
+  variable. Added PCRE2_STATIC variable to the static build using the
+  target_compile_definitions() function.
+
+- Extended the CMake config files.
+
+  - Introduced CMake variable PCRE2_USE_STATIC_LIBS to easily switch between
+    the static and shared libraries.
+
+  - Added the PCRE_STATIC variable to the target compile definitions for the
+    import of the static library.
+
+Building static and shared libraries using MSVC results in a name clash of
+the libraries. Both static and shared library builds create, for example, the
+file pcre2-8.lib. Therefore, I decided to change the static library names by
+adding "-static". For example, pcre2-8.lib has become pcre2-8-static.lib.
+[Comment by PH: this is MSVC-specific. It doesn't happen on Linux.]
+
+3. Increased the minimum release number for CMake to 3.0.0 because older than
+2.8.12 is deprecated (it was set to 2.8.5) and causes warnings. Even 3.0.0 is
+quite old; it was released in 2014.
+
+4. Implemented a modified version of Thomas Tempelmann's pcre2grep patch for
+detecting symlink loops. This is dependent on the availability of realpath(),
+which is now tested for in ./configure and CMakeLists.txt.
+
+5. Implemented a modified version of Thomas Tempelmann's patch for faster
+case-independent "first code unit" searches for unanchored patterns in 8-bit
+mode in the interpreters. Instead of just remembering whether one case matched
+or not, it remembers the position of a previous match so as to avoid
+unnecessary repeated searching.
+
+6. Perl now locks out \K in lookarounds, so PCRE2 now does the same by default.
+However, just in case anybody was relying on the old behaviour, there is an
+option called PCRE2_EXTRA_ALLOW_LOOKAROUND_BSK that enables the old behaviour.
+An option has also been added to pcre2grep to enable this.
+
+7. Re-enable a JIT optimization which was unintentionally disabled in 10.35.
+
+8. There is a loop counter to catch excessively crazy patterns when checking
+the lengths of lookbehinds at compile time. This was incorrectly getting reset
+whenever a lookahead was processed, leading to some fuzzer-generated patterns
+taking a very long time to compile when (?|) was present in the pattern,
+because (?|) disables caching of group lengths.
+
+
+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 synonyms 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 statements 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.

+notice and this notice are preserved.  This file is offered as-is,
+without warranty of any kind.
+
+Basic Installation
+==================
+
+   Briefly, the shell command './configure && make && make install'
+should configure, build, and install this package.  The following
+more-detailed instructions are generic; see the 'README' file for
+instructions specific to this package.  Some packages provide this
+'INSTALL' file but do not implement all of the features documented
+below.  The lack of an optional feature in a given package is not
+necessarily a bug.  More recommendations for GNU packages can be found
+in *note Makefile Conventions: (standards)Makefile Conventions.
+
+   The 'configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a 'Makefile' in each directory of the package.
+It may also create one or more '.h' files containing system-dependent
+definitions.  Finally, it creates a shell script 'config.status' that
+you can run in the future to recreate the current configuration, and a
+file 'config.log' containing compiler output (useful mainly for
+debugging 'configure').
+
+   It can also use an optional file (typically called 'config.cache' and
+enabled with '--cache-file=config.cache' or simply '-C') that saves the
+results of its tests to speed up reconfiguring.  Caching is disabled by
+default to prevent problems with accidental use of stale cache files.
+
+   If you need to do unusual things to compile the package, please try
+to figure out how 'configure' could check whether to do them, and mail
+diffs or instructions to the address given in the 'README' so they can
+be considered for the next release.  If you are using the cache, and at
+some point 'config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+   The file 'configure.ac' (or 'configure.in') is used to create
+'configure' by a program called 'autoconf'.  You need 'configure.ac' if
+you want to change it or regenerate 'configure' using a newer version of
+'autoconf'.
+
+   The simplest way to compile this package is:
+
+  1. 'cd' to the directory containing the package's source code and type
+     './configure' to configure the package for your system.
+
+     Running 'configure' might take a while.  While running, it prints
+     some messages telling which features it is checking for.
+
+  2. Type 'make' to compile the package.
+
+  3. Optionally, type 'make check' to run any self-tests that come with
+     the package, generally using the just-built uninstalled binaries.
+
+  4. Type 'make install' to install the programs and any data files and
+     documentation.  When installing into a prefix owned by root, it is
+     recommended that the package be configured and built as a regular
+     user, and only the 'make install' phase executed with root
+     privileges.
+
+  5. Optionally, type 'make installcheck' to repeat any self-tests, but
+     this time using the binaries in their final installed location.
+     This target does not install anything.  Running this target as a
+     regular user, particularly if the prior 'make install' required
+     root privileges, verifies that the installation completed
+     correctly.
+
+  6. You can remove the program binaries and object files from the
+     source code directory by typing 'make clean'.  To also remove the
+     files that 'configure' created (so you can compile the package for
+     a different kind of computer), type 'make distclean'.  There is
+     also a 'make maintainer-clean' target, but that is intended mainly
+     for the package's developers.  If you use it, you may have to get
+     all sorts of other programs in order to regenerate files that came
+     with the distribution.
+
+  7. Often, you can also type 'make uninstall' to remove the installed
+     files again.  In practice, not all packages have tested that
+     uninstallation works correctly, even though it is required by the
+     GNU Coding Standards.
+
+  8. Some packages, particularly those that use Automake, provide 'make
+     distcheck', which can by used by developers to test that all other
+     targets like 'make install' and 'make uninstall' work correctly.
+     This target is generally not run by end users.
+
+Compilers and Options
+=====================
+
+   Some systems require unusual options for compilation or linking that
+the 'configure' script does not know about.  Run './configure --help'
+for details on some of the pertinent environment variables.
+
+   You can give 'configure' initial values for configuration parameters
+by setting variables in the command line or in the environment.  Here is
+an example:
+
+     ./configure CC=c99 CFLAGS=-g LIBS=-lposix
+
+   *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+   You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you can use GNU 'make'.  'cd' to the
+directory where you want the object files and executables to go and run
+the 'configure' script.  'configure' automatically checks for the source
+code in the directory that 'configure' is in and in '..'.  This is known
+as a "VPATH" build.
+
+   With a non-GNU 'make', it is safer to compile the package for one
+architecture at a time in the source code directory.  After you have
+installed the package for one architecture, use 'make distclean' before
+reconfiguring for another architecture.
+
+   On MacOS X 10.5 and later systems, you can create libraries and
+executables that work on multiple system types--known as "fat" or
+"universal" binaries--by specifying multiple '-arch' options to the
+compiler but only a single '-arch' option to the preprocessor.  Like
+this:
+
+     ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+                 CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+                 CPP="gcc -E" CXXCPP="g++ -E"
+
+   This is not guaranteed to produce working output in all cases, you
+may have to build one architecture at a time and combine the results
+using the 'lipo' tool if you have problems.
+
+Installation Names
+==================
+
+   By default, 'make install' installs the package's commands under
+'/usr/local/bin', include files under '/usr/local/include', etc.  You
+can specify an installation prefix other than '/usr/local' by giving
+'configure' the option '--prefix=PREFIX', where PREFIX must be an
+absolute file name.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+pass the option '--exec-prefix=PREFIX' to 'configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+   In addition, if you use an unusual directory layout you can give
+options like '--bindir=DIR' to specify different values for particular
+kinds of files.  Run 'configure --help' for a list of the directories
+you can set and what kinds of files go in them.  In general, the default
+for these options is expressed in terms of '${prefix}', so that
+specifying just '--prefix' will affect all of the other directory
+specifications that were not explicitly provided.
+
+   The most portable way to affect installation locations is to pass the
+correct locations to 'configure'; however, many packages provide one or
+both of the following shortcuts of passing variable assignments to the
+'make install' command line to change installation locations without
+having to reconfigure or recompile.
+
+   The first method involves providing an override variable for each
+affected directory.  For example, 'make install
+prefix=/alternate/directory' will choose an alternate location for all
+directory configuration variables that were expressed in terms of
+'${prefix}'.  Any directories that were specified during 'configure',
+but not in terms of '${prefix}', must each be overridden at install time
+for the entire installation to be relocated.  The approach of makefile
+variable overrides for each directory variable is required by the GNU
+Coding Standards, and ideally causes no recompilation.  However, some
+platforms have known limitations with the semantics of shared libraries
+that end up requiring recompilation when using this method, particularly
+noticeable in packages that use GNU Libtool.
+
+   The second method involves providing the 'DESTDIR' variable.  For
+example, 'make install DESTDIR=/alternate/directory' will prepend
+'/alternate/directory' before all installation names.  The approach of
+'DESTDIR' overrides is not required by the GNU Coding Standards, and
+does not work on platforms that have drive letters.  On the other hand,
+it does better at avoiding recompilation issues, and works well even
+when some directory options were not specified in terms of '${prefix}'
+at 'configure' time.
+
+Optional Features
+=================
+
+   If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving 'configure' the
+option '--program-prefix=PREFIX' or '--program-suffix=SUFFIX'.
+
+   Some packages pay attention to '--enable-FEATURE' options to
+'configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to '--with-PACKAGE' options, where PACKAGE
+is something like 'gnu-as' or 'x' (for the X Window System).  The
+'README' should mention any '--enable-' and '--with-' options that the
+package recognizes.
+
+   For packages that use the X Window System, 'configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the 'configure' options '--x-includes=DIR' and
+'--x-libraries=DIR' to specify their locations.
+
+   Some packages offer the ability to configure how verbose the
+execution of 'make' will be.  For these packages, running './configure
+--enable-silent-rules' sets the default to minimal output, which can be
+overridden with 'make V=1'; while running './configure
+--disable-silent-rules' sets the default to verbose, which can be
+overridden with 'make V=0'.
+
+Particular systems
+==================
+
+   On HP-UX, the default C compiler is not ANSI C compatible.  If GNU CC
+is not installed, it is recommended to use the following options in
+order to use an ANSI C compiler:
+
+     ./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
+
+and if that doesn't work, install pre-built binaries of GCC for HP-UX.
+
+   HP-UX 'make' updates targets which have the same timestamps as their
+prerequisites, which makes it generally unusable when shipped generated
+files such as 'configure' are involved.  Use GNU 'make' instead.
+
+   On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
+parse its '<wchar.h>' header file.  The option '-nodtk' can be used as a
+workaround.  If GNU CC is not installed, it is therefore recommended to
+try
+
+     ./configure CC="cc"
+
+and if that doesn't work, try
+
+     ./configure CC="cc -nodtk"
+
+   On Solaris, don't put '/usr/ucb' early in your 'PATH'.  This
+directory contains several dysfunctional programs; working variants of
+these programs are available in '/usr/bin'.  So, if you need '/usr/ucb'
+in your 'PATH', put it _after_ '/usr/bin'.
+
+   On Haiku, software installed for all users goes in '/boot/common',
+not '/usr/local'.  It is recommended to use the following options:
+
+     ./configure --prefix=/boot/common
+
+Specifying the System Type
+==========================
+
+   There may be some features 'configure' cannot figure out
+automatically, but needs to determine by the type of machine the package
+will run on.  Usually, assuming the package is built to be run on the
+_same_ architectures, 'configure' can figure that out, but if it prints
+a message saying it cannot guess the machine type, give it the
+'--build=TYPE' option.  TYPE can either be a short name for the system
+type, such as 'sun4', or a canonical name which has the form:
+
+     CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+     OS
+     KERNEL-OS
+
+   See the file 'config.sub' for the possible values of each field.  If
+'config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+   If you are _building_ compiler tools for cross-compiling, you should
+use the option '--target=TYPE' to select the type of system they will
+produce code for.
+
+   If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with '--host=TYPE'.
+
+Sharing Defaults
+================
+
+   If you want to set default values for 'configure' scripts to share,
+you can create a site shell script called 'config.site' that gives
+default values for variables like 'CC', 'cache_file', and 'prefix'.
+'configure' looks for 'PREFIX/share/config.site' if it exists, then
+'PREFIX/etc/config.site' if it exists.  Or, you can set the
+'CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all 'configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+   Variables not defined in a site shell script can be set in the
+environment passed to 'configure'.  However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost.  In order to avoid this problem, you should set
+them in the 'configure' command line, using 'VAR=value'.  For example:
+
+     ./configure CC=/usr/local2/bin/gcc
+
+causes the specified 'gcc' to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+Unfortunately, this technique does not work for 'CONFIG_SHELL' due to an
+Autoconf limitation.  Until the limitation is lifted, you can use this
+workaround:
+
+     CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+'configure' Invocation
+======================
+
+   'configure' recognizes the following options to control how it
+operates.
+
+'--help'
+'-h'
+     Print a summary of all of the options to 'configure', and exit.
+
+'--help=short'
+'--help=recursive'
+     Print a summary of the options unique to this package's
+     'configure', and exit.  The 'short' variant lists options used only
+     in the top level, while the 'recursive' variant lists options also
+     present in any nested packages.
+
+'--version'
+'-V'
+     Print the version of Autoconf used to generate the 'configure'
+     script, and exit.
+
+'--cache-file=FILE'
+     Enable the cache: use and save the results of the tests in FILE,
+     traditionally 'config.cache'.  FILE defaults to '/dev/null' to
+     disable caching.
+
+'--config-cache'
+'-C'
+     Alias for '--cache-file=config.cache'.
+
+'--quiet'
+'--silent'
+'-q'
+     Do not print messages saying which checks are being made.  To
+     suppress all normal output, redirect it to '/dev/null' (any error
+     messages will still be shown).
+
+'--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     'configure' can determine that directory automatically.
+
+'--prefix=DIR'
+     Use DIR as the installation prefix.  *note Installation Names:: for
+     more details, including other options available for fine-tuning the
+     installation locations.
+
+'--no-create'
+'-n'
+     Run the configure checks, but stop before creating any output
+     files.
+
+'configure' also accepts some other, not widely useful, options.  Run
+'configure --help' for more details.

+News about PCRE2 releases
+-------------------------
+
+
+Version 10.42 11-December-2022
+------------------------------
+
+This is an unexpectedly early release to fix a problem that was introduced in
+10.41. ChangeLog number 19 (GitHub #139) added the default definition of
+PCRE2_CALL_CONVENTION to pcre2posix.c instead of pcre2posix.h, which meant that
+programs including pcre2posix.h but not pcre2.h couldn't compile. A new test
+that checks this case has been added.
+
+A couple of other minor issues are also fixed, and a patch for an intermittent
+JIT fault is also included. See ChangeLog and the Git log.
+
+
+Version 10.41 06-December-2022
+------------------------------
+
+This is another mainly bug-fixing and code-tidying release. There is one
+significant upgrade to pcre2grep: it now behaves like GNU grep when matching
+more than one pattern and a later pattern matches at an earlier point in the
+subject when the matched substrings are being identified by colour or by
+offsets.
+
+
+Version 10.40 15-April-2022
+---------------------------
+
+This is mostly a bug-fixing and code-tidying release. However, there are some
+extensions to Unicode property handling:
+
+* Added support for Bidi_Class and a number of binary Unicode properties,
+including Bidi_Control.
+
+* A number of changes to script matching for \p and \P:
+
+  (a) Script extensions for a character are now coded as a bitmap instead of
+      a list of script numbers, which should be faster and does not need a
+      loop.
+
+  (b) Added the syntax \p{script:xxx} and \p{script_extensions:xxx} (synonyms
+      sc and scx).
+
+  (c) Changed \p{scriptname} from being the same as \p{sc:scriptname} to being
+      the same as \p{scx:scriptname} because this change happened in Perl at
+      release 5.26.
+
+  (d) The standard Unicode 4-letter abbreviations for script names are now
+      recognized.
+
+  (e) In accordance with Unicode and Perl's "loose matching" rules, spaces,
+      hyphens, and underscores are ignored in property names, which are then
+      matched independent of case.
+
+As always, see ChangeLog for a list of all changes (also the Git log).
+
+
+Version 10.39 29-October-2021
+-----------------------------
+
+This release is happening soon after 10.38 because the bug fix is important.
+
+1. Fix incorrect detection of alternatives in first character search in JIT.
+
+2. Update to Unicode 14.0.0.
+
+3. Some code cleanups (see ChangeLog).
+
+
+Version 10.38 01-October-2021
+-----------------------------
+
+As well as some bug fixes and tidies (as always, see ChangeLog for details),
+the documentation is updated to list the new URLs, following the move of the
+source repository to GitHub and the mailing list to Google Groups.
+
+* The CMake build system can now build both static and shared libraries in one
+go.
+
+* Following Perl's lead, \K is now locked out in lookaround assertions by
+default, but an option is provided to re-enable the previous behaviour.
+
+
+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.

+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 no longer maintained. The latest release of PCRE2 is available
+in .tar.gz, tar.bz2, or .zip form from this GitHub repository:
+
+https://github.com/PCRE2Project/pcre2/releases
+
+There is a mailing list for discussion about the development of PCRE2 at
+pcre2-dev@googlegroups.com. You can subscribe by sending an email to
+pcre2-dev+subscribe@googlegroups.com.
+
+You can access the archives and also subscribe or manage your subscription
+here:
+
+https://groups.google.com/g/pcre2-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
+  Building PCRE2 using autotools

+
+
+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.
+
+If you have downloaded and unpacked a PCRE2 release tarball, run the
+"configure" command from the PCRE2 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.
+
+The files in the GitHub repository do not contain "configure". If you have
+downloaded the PCRE2 source files from GitHub, before you can run "configure"
+you must run the shell script called autogen.sh. This runs a number of
+autotools to create a "configure" script (you must of course have the autotools
+commands installed in order to do this).
+
+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 a subset of Unicode properties are supported; see the
+  pcre2pattern man page for details. 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 option 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 versions earlier than 2013
+  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 of %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 what 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 because 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, pcre2posix_test, 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 the 8-bit library is built, a test program for the POSIX wrapper, called
+pcre2posix_test, is compiled, and when JIT support is enabled, a test program
+called pcre2_jit_test is built. The scripts and the program tests are all run
+when 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 interpretive
+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.
+
+Test 26 checks Unicode property support using tests that are generated
+automatically from the Unicode data tables.
+
+
+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_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.

+# PCRE2 - Perl-Compatible Regular Expressions
+
+The PCRE2 library is a set of C functions that implement regular expression
+pattern matching using the same syntax and semantics as Perl 5. PCRE2 has its
+own native API, as well as a set of wrapper functions that correspond to the
+POSIX regular expression API. The PCRE2 library is free, even for building 
+proprietary software. It comes in three forms, for processing 8-bit, 16-bit,
+or 32-bit code units, in either literal or UTF encoding.
+
+PCRE2 was first released in 2015 to replace the API in the original PCRE 
+library, which is now obsolete and no longer maintained. As well as a more
+flexible API, the code of PCRE2 has been much improved since the fork.
+ 
+## Download
+
+As well as downloading from the 
+[GitHub site](https://github.com/PCRE2Project/pcre2), you can download PCRE2 
+or the older, unmaintained PCRE1 library from an 
+[*unofficial* mirror](https://sourceforge.net/projects/pcre/files/) at SourceForge.
+
+You can check out the PCRE2 source code via Git or Subversion:
+
+    git clone https://github.com/PCRE2Project/pcre2.git
+    svn co    https://github.com/PCRE2Project/pcre2.git
+
+## Contributed Ports
+
+If you just need the command-line PCRE2 tools on Windows, precompiled binary
+versions are available at this 
+[Rexegg page](http://www.rexegg.com/pcregrep-pcretest.html).
+
+A PCRE2 port for z/OS, a mainframe operating system which uses EBCDIC as its
+default character encoding, can be found at 
+[http://www.cbttape.org](http://www.cbttape.org/) (File 939).
+
+## Documentation
+
+You can read the PCRE2 documentation 
+[here](https://PCRE2Project.github.io/pcre2/doc/html/index.html).
+
+Comparisons to Perl's regular expression semantics can be found in the
+community authored Wikipedia entry for PCRE.
+
+There is a curated summary of changes for each PCRE release, copies of
+documentation from older releases, and other useful information from the third
+party authored 
+[RexEgg PCRE Documentation and Change Log page](http://www.rexegg.com/pcre-documentation.html).
+
+## Contact
+
+To report a problem with the PCRE2 library, or to make a feature request, please
+use the PCRE2 GitHub issues tracker. There is a mailing list for discussion of
+ PCRE2 issues and development at pcre2-dev@googlegroups.com, which is where any
+announcements will be made. You can browse the 
+[list archives](https://groups.google.com/g/pcre2-dev).

+          one of PCRE's special properties such as ALNUM or SPACE or WORD.
+          Only WORD actually needs all four entries, but using repeats for the
+          others means they can all use the same code below.
+
+          The first two entries in each row are Unicode general categories, and
+          apply always, because all the characters they include are part of the
+          PCRE character set. The third and fourth entries are a general and a
+          particular category, respectively, that include one or more relevant
+          characters. One or the other is used, depending on whether the check
+          is for a general or a particular category. However, in both cases the
+          category contains more characters than the specials that are defined
+          for the property being tested against. Therefore, it cannot be used
+          in a NOTPROP case.
+
+          Example: the row for WORD contains ucp_L, ucp_N, ucp_P, ucp_Po.
+          Underscore is covered by ucp_P or ucp_Po. */

+
+This function is also called from pcre2_substitute() to handle escape sequences
+in replacement strings. In this case, the cb argument is NULL, and in the case
+of escapes that have further processing, only sequences that define a data
+character are recognised. The isclass argument is not relevant; the options
+argument is the final value of the compiled pattern's options.

+/* This function is called when the sequence "[:" or "[." or "[=" is
+encountered in a character class. It checks whether this is followed by a
+sequence of characters terminated by a matching ":]" or ".]" or "=]". If we
+reach an unescaped ']' without the special preceding character, return FALSE.
+
+Originally, this function only recognized a sequence of letters between the
+terminators, but it seems that Perl recognizes any sequence of characters,
+though of course unknown POSIX names are subsequently rejected. Perl gives an
+"Unknown POSIX class" error for [:f\oo:] for example, where previously PCRE
+didn't consider this to be a POSIX class. Likewise for [:1234:].
+
+The problem in trying to be exactly like Perl is in the handling of escapes. We
+have to be sure that [abc[:x\]pqr] is *not* treated as containing a POSIX
+class, but [abc[:x\]pqr:]] is (so that an error can be generated). The code
+below handles the special cases \\ and \], but does not try to do any other
+escape processing. This makes it different from Perl for cases such as
+[:l\ower:] where Perl recognizes it as the POSIX class "lower" but PCRE does
+not recognize "l\ower". This is a lesser evil than not diagnosing bad classes
+when Perl does, I think.
+
+A user pointed out that PCRE was rejecting [:a[:digit:]] whereas Perl was not.
+It seems that the appearance of a nested POSIX class supersedes an apparent
+external class. For example, [:a[:digit:]b:] matches "a", "b", ":", or
+a digit. This is handled by returning FALSE if the start of a new group with
+the same terminator is encountered, since the next closing sequence must close
+the nested group, not the outer one.
+
+In Perl, unescaped square brackets may also appear as part of class names. For
+example, [:a[:abc]b:] gives unknown POSIX class "[:abc]b:]". However, for
+[:a[:abc]b][b:] it gives unknown POSIX class "[:abc]b][b:]", which does not
+seem right at all. PCRE does not allow closing square brackets in POSIX class
+names.

+can cope with, allowing it to run on SunOS4 and other "close to standard"
+systems.
+
+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
+HAVE_BCOPY is defined. If your system has neither bcopy() nor memmove(), make

+/* This module contains the external function pcre2_dfa_match(), which is an
+alternative matching function that uses a sort of DFA algorithm (not a true
+FSM). This is NOT Perl-compatible, but it has advantages in certain
+applications. */
+
+
+/* NOTE ABOUT PERFORMANCE: A user of this function sent some code that improved
+the performance of his patterns greatly. I could not use it as it stood, as it
+was not thread safe, and made assumptions about pattern sizes. Also, it caused
+test 7 to loop, and test 9 to crash with a segfault.
+
+The issue is the check for duplicate states, which is done by a simple linear
+search up the state list. (Grep for "duplicate" below to find the code.) For
+many patterns, there will never be many states active at one time, so a simple
+linear search is fine. In patterns that have many active states, it might be a
+bottleneck. The suggested code used an indexing scheme to remember which states
+had previously been used for each character, and avoided the linear search when
+it knew there was no chance of a duplicate. This was implemented when adding
+states to the state lists.
+
+I wrote some thread-safe, not-limited code to try something similar at the time
+of checking for duplicates (instead of when adding states), using index vectors
+on the stack. It did give a 13% improvement with one specially constructed
+pattern for certain subject strings, but on other strings and on many of the
+simpler patterns in the test suite it did worse. The major problem, I think,
+was the extra time to initialize the index. This had to be done for each call
+of internal_dfa_match(). (The supplied patch used a static vector, initialized
+only once - I suspect this was the cause of the problems with the tests.)
+
+Overall, I concluded that the gains in some cases did not outweigh the losses
+in others, so I abandoned this code. */

+
+Arguments:
+  code          points to the compiled pattern
+  subject       subject string
+  length        length of subject string
+  startoffset   where to start matching in the subject

+/* If PCRE2 is to support UTF-8 on EBCDIC platforms, we cannot use normal
+character constants like '*' because the compiler would emit their EBCDIC code,
+which is different from their ASCII/UTF-8 code. Instead we define macros for
+the characters so that they always use the ASCII/UTF-8 code when UTF-8 support
+is enabled. When UTF-8 support is not enabled, the definitions use character
+literals. Both character and string versions of each character are needed, and
+there are some longer strings as well.
+
+This means that, on EBCDIC platforms, the PCRE2 library can handle either
+EBCDIC, or UTF-8, but not both. To support both in the same compiled library
+would need different lookups depending on whether PCRE2_UTF was set or not.
+This would make it impossible to use characters in switch/case statements,
+which would reduce performance. For a theoretical use (which nobody has asked
+for) in a minority area (EBCDIC platforms), this is not sensible. Any
+application that did need both could compile two versions of the library, using
+macros to give the functions distinct names. */

+/* UTF-8 support is not enabled; use the platform-dependent character literals
+so that PCRE2 works in both ASCII and EBCDIC environments, but only in non-UTF
+mode. Newline characters are problematic in EBCDIC. Though it has CR and LF
+characters, a common practice has been to use its NL (0x15) character as the
+line terminator in C-like processing environments. However, sometimes the LF
+(0x25) character is used instead, according to this Unicode document:
+
+http://unicode.org/standard/reports/tr13/tr13-5.html
+
+PCRE2 defaults EBCDIC NL to 0x15, but has a build-time option to select 0x25
+instead. Whichever is *not* chosen is defined as NEL.
+
+In both ASCII and EBCDIC environments, CHAR_NL and CHAR_LF are synonyms for the
+same code point. */

+Short summary about the backtracking mechanism empolyed by the jit code generator:
+
+The code generator follows the recursive nature of the PERL compatible regular
+expressions. The basic blocks of regular expressions are condition checkers
+whose execute different commands depending on the result of the condition check.
+The relationship between the operators can be horizontal (concatenation) and
+vertical (sub-expression) (See struct backtrack_common for more details).
+
+  'ab' - 'a' and 'b' regexps are concatenated
+  'a+' - 'a' is the sub-expression of the '+' operator
+
+The condition checkers are boolean (true/false) checkers. Machine code is generated
+for the checker itself and for the actions depending on the result of the checker.
+The 'true' case is called as the matching path (expected path), and the other is called as
+the 'backtrack' path. Branch instructions are expesive for all CPUs, so we avoid taken
+branches on the matching path.
+
+ Greedy star operator (*) :
+   Matching path: match happens.
+   Backtrack path: match failed.
+ Non-greedy star operator (*?) :
+   Matching path: no need to perform a match.
+   Backtrack path: match is required.
+
+The following example shows how the code generated for a capturing bracket
+with two alternatives. Let A, B, C, D are arbirary regular expressions, and
+we have the following regular expression:
+
+   A(B|C)D
+
+The generated code will be the following:
+
+ A matching path
+ '(' matching path (pushing arguments to the stack)
+ B matching path
+ ')' matching path (pushing arguments to the stack)
+ D matching path
+ return with successful match
+
+ D backtrack path
+ ')' backtrack path (If we arrived from "C" jump to the backtrack of "C")
+ B backtrack path
+ C expected path
+ jump to D matching path
+ C backtrack path
+ A backtrack path
+
+ Notice, that the order of backtrack code paths are the opposite of the fast
+ code paths. In this way the topmost value on the stack is always belong
+ to the current backtrack code path. The backtrack path must check
+ whether there is a next alternative. If so, it needs to jump back to
+ the matching path eventually. Otherwise it needs to clear out its own stack
+ frame and continue the execution on the backtrack code paths.
+*/
+
+/*
+Saved stack frames:
+
+Atomic blocks and asserts require reloading the values of private data
+when the backtrack mechanism performed. Because of OP_RECURSE, the data
+are not necessarly known in compile time, thus we need a dynamic restore
+mechanism.
+
+The stack frames are stored in a chain list, and have the following format:
+([ capturing bracket offset ][ start value ][ end value ])+ ... [ 0 ] [ previous head ]
+
+Thus we can restore the private data to a particular point in the stack.

+                   "Recursion" in the match() function
+
+The original match() function was highly recursive, but this proved to be the
+source of a number of problems over the years, mostly because of the relatively
+small system stacks that are commonly found. As new features were added to
+patterns, various kludges were invented to reduce the amount of stack used,
+making the code hard to understand in places.
+
+A version did exist that used individual frames on the heap instead of calling
+match() recursively, but this ran substantially slower. The current version is
+a refactoring that uses a vector of frames to remember backtracking points.
+This runs no slower, and possibly even a bit faster than the original recursive
+implementation.
+
+At first, an initial vector of size START_FRAMES_SIZE (enough for maybe 50
+frames) was allocated on the system stack. If this was not big enough, the heap
+was used for a larger vector. However, it turns out that there are environments
+where taking as little as 20KiB from the system stack is an embarrassment.
+After another refactoring, the heap is used exclusively, but a pointer the
+frames vector and its size are cached in the match_data block, so that there is
+no new memory allocation if the same match_data block is used for multiple
+matches (unless the frames vector has to be extended).

+(i.e. something has been matched, even if not part of the actual matched
+string), or (b) the pattern contains a lookbehind. These are the conditions for

+10 and 11. The 2-dimensional table is indexed by the properties of two adjacent

+
+The value is non-zero if a grapheme break is NOT permitted between the relevant
+two code points. The breaking rules are as follows:
+
+1. Break at the start and end of text (pretty obviously).
+
+2. Do not break between a CR and LF; otherwise, break before and after
+   controls.
+
+3. Do not break Hangul syllable sequences, the rules for which are:
+
+    L may be followed by L, V, LV or LVT
+    LV or V may be followed by V or T
+    LVT or T may be followed by T
+
+4. Do not break before extending characters or zero-width-joiner (ZWJ).
+
+The following rules are only for extended grapheme clusters (but that's what we
+are implementing).
+
+5. Do not break before SpacingMarks.
+
+6. Do not break after Prepend characters.
+
+7. Do not break within emoji modifier sequences or emoji zwj sequences. That
+   is, do not break between characters with the Extended_Pictographic property.
+   Extend and ZWJ characters are allowed between the characters; this cannot be
+   represented in this table, the code has to deal with it.
+
+8. Do not break within emoji flag sequences. That is, do not break between
+   regional indicator (RI) symbols if there are an odd number of RI characters
+   before the break point. This table encodes "join RI characters"; the code
+   has to deal with checking for previous adjoining RIs.
+
+9. Otherwise, break everywhere.

+/* The PRIV(utt)[] table below translates Unicode property names into type and
+code values. It is searched by binary chop, so must be in collating sequence of
+name. Originally, the table contained pointers to the name strings in the first
+field of each entry. However, that leads to a large number of relocations when
+a shared library is dynamically loaded. A significant reduction is made by
+putting all the names into a single, large string and using offsets instead.
+All letters are lower cased, and underscores are removed, in accordance with
+the "loose matching" rules that Unicode advises and Perl uses. */

+   This file contains a simple executable memory allocator
+
+   It is assumed, that executable code blocks are usually medium (or sometimes
+   large) memory blocks, and the allocator is not too frequently called (less
+   optimized than other allocators). Thus, using it as a generic allocator is
+   not suggested.
+
+   How does it work:
+     Memory is allocated in continuous memory areas called chunks by alloc_chunk()
+     Chunk format:
+     [ block ][ block ] ... [ block ][ block terminator ]
+
+   All blocks and the block terminator is started with block_header. The block
+   header contains the size of the previous and the next block. These sizes
+   can also contain special values.
+     Block size:
+       0 - The block is a free_block, with a different size member.
+       1 - The block is a block terminator.
+       n - The block is used at the moment, and the value contains its size.
+     Previous block size:
+       0 - This is the first block of the memory chunk.
+       n - The size of the previous block.
+
+   Using these size values we can go forward or backward on the block chain.
+   The unused blocks are stored in a chain list pointed by free_blocks. This
+   list is useful if we need to find a suitable memory area when the allocator
+   is called.
+
+   When a block is freed, the new free block is connected to its adjacent free
+   blocks if possible.
+
+     [ free block ][ used block ][ free block ]
+   and "used block" is freed, the three blocks are connected together:
+     [           one big free block           ]

+   ------------------------------------------------------------------------
+    Stack-Less JIT compiler for multiple architectures (x86, ARM, PowerPC)
+   ------------------------------------------------------------------------
+
+   Short description
+    Advantages:
+      - The execution can be continued from any LIR instruction. In other
+        words, it is possible to jump to any label from anywhere, even from
+        a code fragment, which is compiled later, as long as the compiling
+        context is the same. See sljit_emit_enter for more details.
+      - Supports self modifying code: target of any jump and call
+        instructions and some constant values can be dynamically modified
+        during runtime. See SLJIT_REWRITABLE_JUMP.
+        - although it is not suggested to do it frequently
+        - can be used for inline caching: save an important value once
+          in the instruction stream
+      - A fixed stack space can be allocated for local variables
+      - The compiler is thread-safe
+      - The compiler is highly configurable through preprocessor macros.
+        You can disable unneeded features (multithreading in single
+        threaded applications), and you can use your own system functions
+        (including memory allocators). See sljitConfig.h.
+    Disadvantages:
+      - The compiler is more like a platform independent assembler, so
+        there is no built-in variable management. Registers and stack must
+        be managed manually (the name of the compiler refers to this).
+    In practice:
+      - This approach is very effective for interpreters
+        - One of the saved registers typically points to a stack interface
+        - It can jump to any exception handler anytime (even if it belongs
+          to another function)
+        - Hot paths can be modified during runtime reflecting the changes
+          of the fastest execution path of the dynamic language
+        - SLJIT supports complex memory addressing modes
+        - mainly position and context independent code (except some cases)
+
+    For valgrind users:
+      - pass --smc-check=all argument to valgrind, since JIT is a "self-modifying code"

+  Scratch (R) registers: registers which may not preserve their values
+  across function calls.
+
+  Saved (S) registers: registers which preserve their values across
+  function calls.
+
+  The scratch and saved register sets overlap. The last scratch register
+  is the first saved register, the one before the last is the second saved
+  register, and so on.
+
+  If an architecture provides two scratch and three saved registers,
+  its scratch and saved register sets are the following:
+
+     R0   |        |   R0 is always a scratch register
+     R1   |        |   R1 is always a scratch register
+    [R2]  |   S2   |   R2 and S2 represent the same physical register
+    [R3]  |   S1   |   R3 and S1 represent the same physical register
+    [R4]  |   S0   |   R4 and S0 represent the same physical register
+
+  Note: SLJIT_NUMBER_OF_SCRATCH_REGISTERS would be 2 and
+        SLJIT_NUMBER_OF_SAVED_REGISTERS would be 3 for this architecture.
+
+  Note: On all supported architectures SLJIT_NUMBER_OF_REGISTERS >= 12
+        and SLJIT_NUMBER_OF_SAVED_REGISTERS >= 6. However, 6 registers
+        are virtual on x86-32. See below.
+
+  The purpose of this definition is convenience: saved registers can
+  be used as extra scratch registers. For example four registers can
+  be specified as scratch registers and the fifth one as saved register
+  on the CPU above and any user code which requires four scratch
+  registers can run unmodified. The SLJIT compiler automatically saves
+  the content of the two extra scratch register on the stack. Scratch
+  registers can also be preserved by saving their value on the stack
+  but this needs to be done manually.
+
+  Note: To emphasize that registers assigned to R2-R4 are saved
+        registers, they are enclosed by square brackets.
+
+  Note: sljit_emit_enter and sljit_set_context defines whether a register
+        is S or R register. E.g: when 3 scratches and 1 saved is mapped
+        by sljit_emit_enter, the allowed register set will be: R0-R2 and
+        S0. Although S2 is mapped to the same position as R2, it does not
+        available in the current configuration. Furthermore the S1 register
+        is not available at all.

+
+   As for sljit_emit_call and sljit_emit_icall, the first integer argument

+   Similarly the first floating point argument must be placed into SLJIT_FR0,

+
+   As for sljit_emit_enter, the integer arguments can be stored in scratch
+   or saved registers. The first integer argument without _R postfix is
+   stored in SLJIT_S0, the next one in SLJIT_S1, and so on. The integer
+   arguments with _R postfix are placed into scratch registers. The index
+   of the scratch register is the count of the previous integer arguments
+   starting from SLJIT_R0. The floating point arguments are always placed

+
+   Note: if a function is called by sljit_emit_call/sljit_emit_icall and
+         an argument is stored in a scratch register by sljit_emit_enter,
+         that argument uses the same scratch register index for both

+   the lower 32 bits of the input registers are used, and the CPU status
+   flags are set according to the 32 bit result. Although the higher 32 bit
+   of the input and the result registers are not defined by SLJIT, it might
+   be defined by the CPU architecture (e.g. MIPS). To satisfy these CPU
+   requirements all source registers must be the result of those operations
+   where this option was also set. Memory loads read 32 bit values rather
+   than 64 bit ones. In other words 32 bit and 64 bit operations cannot be
+   mixed. The only exception is SLJIT_MOV32 which source register can hold
+   any 32 or 64 bit value, and it is converted to a 32 bit compatible format
+   first. When the source and destination registers are the same, this
+   conversion is free (no instructions are emitted) on most CPUs. A 32 bit
+   value can also be converted to a 64 bit value by SLJIT_MOV_S32
+   (sign extension) or SLJIT_MOV_U32 (zero extension).
+
+   As for floating-point operations, this option sets 32 bit single
+   precision mode. Similar to the integer operations, all register arguments
+   must be the result of those operations where this option was also set.
+
+   Note: memory addressing always uses 64 bit values on 64 bit systems so
+         the result of a 32 bit operation must not be used with SLJIT_MEMx
+         macros.
+

+
+/* Many CPUs (x86, ARM, PPC) have status flag bits which can be set according
+   to the result of an operation. Other CPUs (MIPS) do not have status
+   flag bits, and results must be stored in registers. To cover both
+   architecture types efficiently only two flags are defined by SLJIT:
+
+    * Zero (equal) flag: it is set if the result is zero
+    * Variable flag: its value is defined by the arithmetic operation
+
+   SLJIT instructions can set any or both of these flags. The value of
+   these flags is undefined if the instruction does not specify their
+   value. The description of each instruction contains the list of
+   allowed flag types.
+
+   Note: the logical or operation can be used to set flags.
+
+   Example: SLJIT_ADD can set the Z, OVERFLOW, CARRY flags hence
+
+     sljit_op2(..., SLJIT_ADD, ...)
+       Both the zero and variable flags are undefined so they can
+       have any value after the operation is completed.
+
+     sljit_op2(..., SLJIT_ADD | SLJIT_SET_Z, ...)
+       Sets the zero flag if the result is zero, clears it otherwise.
+       The variable flag is undefined.
+
+     sljit_op2(..., SLJIT_ADD | SLJIT_SET_OVERFLOW, ...)
+       Sets the variable flag if an integer overflow occurs, clears
+       it otherwise. The zero flag is undefined.
+
+     sljit_op2(..., SLJIT_ADD | SLJIT_SET_Z | SLJIT_SET_CARRY, ...)
+       Sets the zero flag if the result is zero, clears it otherwise.
+       Sets the variable flag if unsigned overflow (carry) occurs,
+       clears it otherwise.
+
+   Certain instructions (e.g. SLJIT_MOV) does not modify flags, so
+   status flags are unchanged.
+
+   Example:
+
+     sljit_op2(..., SLJIT_ADD | SLJIT_SET_Z, ...)
+     sljit_op1(..., SLJIT_MOV, ...)
+       Zero flag is set according to the result of SLJIT_ADD.
+
+     sljit_op2(..., SLJIT_ADD | SLJIT_SET_Z, ...)
+     sljit_op2(..., SLJIT_ADD, ...)
+       Zero flag has unknown value.
+
+   These flags can be used for code optimization. E.g. a fast loop can be
+   implemented by decreasing a counter register and set the zero flag
+   using a single instruction. The zero register can be used by a
+   conditional jump to restart the loop. A single comparison can set a
+   zero and less flags to check if a value is less, equal, or greater
+   than another value.
+
+   Motivation: although some CPUs can set a large number of flag bits,
+   usually their values are ignored or only a few of them are used. Emulating
+   a large number of flags on systems without a flag register is complicated
+   so SLJIT instructions must specify the flag they want to use and only
+   that flag is computed. The last arithmetic instruction can be repeated if
+   multiple flags need to be checked.

+   This file contains a simple executable memory allocator
+
+   It is assumed, that executable code blocks are usually medium (or sometimes
+   large) memory blocks, and the allocator is not too frequently called (less
+   optimized than other allocators). Thus, using it as a generic allocator is
+   not suggested.
+
+   How does it work:
+     Memory is allocated in continuous memory areas called chunks by alloc_chunk()
+     Chunk format:
+     [ block ][ block ] ... [ block ][ block terminator ]
+
+   All blocks and the block terminator is started with block_header. The block
+   header contains the size of the previous and the next block. These sizes
+   can also contain special values.
+     Block size:
+       0 - The block is a free_block, with a different size member.
+       1 - The block is a block terminator.
+       n - The block is used at the moment, and the value contains its size.
+     Previous block size:
+       0 - This is the first block of the memory chunk.
+       n - The size of the previous block.
+
+   Using these size values we can go forward or backward on the block chain.
+   The unused blocks are stored in a chain list pointed by free_blocks. This
+   list is useful if we need to find a suitable memory area when the allocator
+   is called.
+
+   When a block is freed, the new free block is connected to its adjacent free
+   blocks if possible.
+
+     [ free block ][ used block ][ free block ]
+   and "used block" is freed, the three blocks are connected together:
+     [           one big free block           ]

+/*
+   This file contains a simple W^X executable memory allocator for POSIX
+   like systems and Windows
+
+   In *NIX, MAP_ANON is required (that is considered a feature) so make
+   sure to set the right availability macros for your system or the code
+   will fail to build.
+
+   If your system doesn't support mapping of anonymous pages (ex: IRIX) it
+   is also likely that it doesn't need this allocator and should be using
+   the standard one instead.
+
+   It allocates a separate map for each code block and may waste a lot of
+   memory, because whatever was requested, will be rounded up to the page
+   size (minimum 4KB, but could be even bigger).
+
+   It changes the page permissions (RW <-> RX) as needed and therefore, if you
+   will be updating the code after it has been generated, need to make sure to
+   block any concurrent execution, or could result in a SIGBUS, that could
+   even manifest itself at a different address than the one that was being
+   modified.
+
+   Only use if you are unable to use the regular allocator because of security
+   restrictions and adding exceptions to your application or the system are
+   not possible.
