[PATCH] libpcre2: upgrade 10.39 -> 10.40


License-Update: year updated to 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

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

(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

(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

23. Fixed a unicode properrty 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

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
