File tidies, preparing for 8.32-RC1.
Support (*UTF) in all libraries.
Last minute fixes and some documentation update in the JIT compiler.
Temporarily remove 32-bit masking Remove the masking via the PCRE_NO_UTF32_CHECK. It will be reintroduced as a dedicated runtime option later, with support for JIT and non-JIT cases.
Fix compile-time assertion to test the right thing The assertion needs to test that the *public* definition of the 32-bit character is a 32-bit integer type, not the *private* definition.
Rewrite 32-bit GETCHAR* macros Move the high-bit masking to a dedicated macro, and use that in the GETCHAR* and RAWUCHAR* macros.
Add more safety parentheses to macros
JIT native interface.
Use CHAR_NULL in pcre_compile when checking for character zero.
Add a definition for CHAR_NULL (helpful for the z/OS port).
Fix -Wundef warnings when stdint.h is not available Pointed out by Daniel Richard G. on the mailing list.
valgrind: Add --support-valgrind configure option When --enable-valgrind is passed, PCRE will annotate some memory regions as unaddressable, aiding in finding invalid memory accesses when running under valgrind. This is useful mostly for debugging PCRE itself, and thus probably should not be enabled in release builds.
Clean up compiler warnings for pcre_exec.c in all modes.
Get rid of compiler warnings from pcre_compile.c in all modes.
Change comment.
pcre32: Fix signed-unsigned compare
Make ucp_gentype unsigned int It's compared against unsigned values, so change it to unsigned to quit a few -Wsign-compare warnings.
pcre32: Remove unnecessary ifdefing Just define HAS_EXTRALEN etc to 0. This reduces the amount of #ifdef COMPILE_PCRE32.
pcre32: Remove unnecessary space
pcre32: exec: Mask bits > 21 in 32-bit UTF mode Allow passing characters with high bits set in UTF-32 mode.
pcre32: pcretest: Don't convert data line to UTF-8 first
While reading the data lines, directly put them into the 8, 16 or
32 bit buffers instead of first converting them into UTF-8 and only
afterwards converting that buffer to 16/32 bit. This is necessary so
the in 32 bit mode the \x{} escapes can use the full 32-bit range
(while the non-standard 5/6 byte UTF-8 sequences can only express
characters up to 31-bits).
pcre32: Mask out bits >= 22 on 32-bit characters in UTF-32 mode UTF-32 only uses 21 bits, so the upper bits may be used to store flags etc. To allow passing the unmodified internal buffers to pcre32, make pcre32 mask out those upper bits. TODO: do the same for the JIT compiler, and add tests
pcre32: compile: Separate first/req char flags from the character itself This is necessary so that 32-bit characters in non-UTF-32 mode can be from the whole 32-bit range.
pcre32: compile: Fix signed/unsigned mismatch in GET_UCD
pcre32: compile: Encode back references as negative numbers Return the back reference as negative numbers from check_escape(), instead of adding them to ESC_REF. This way, there will never be an overflow.
pcre32: compile: Make check_escape return the data character in an out param check_escape needs to return both the escape code and possibly a data character. Return the data character in an out param instead of mixing it with the escape code; this is in preparation to making the character a pcre_uint32 to enable the full 32-bit range in pcre32 in non-UTF-32 mode.
pcre32: xclass: Use pcre_uint32 for characters This fixes character classes for 32-bit in non-UTF-32 mode.
pcre32: Add 32-bit library Create libpcre32 that operates on 32-bit characters (UTF-32). This turned out to be surprisingly simple after the UTF-16 support was introduced; mostly just extra ifdefs and adjusting and adding some tests.
All the remaining changes for handling characters with more than one other case.
Update character class handling to use new character case information; rework \h, \H, \v, and \V to use the same apparatus with centrally defined lists.
Update MultiStage2.py to create new case-folding information in the Unicode tables.
New "case" macros did not work in EBCDIC mode.
Turn case lists for horizontal and vertical white space into macros so they are defined only once.
General spring-clean of EBCDIC-related issues in the code, which had decayed over time. Also the documentation. Added one test that can be run in an ASCII world to do a little testing of EBCDIC-related things.
Set config.h NEWLINE values appropriately for EBCDIC, adding --enable-ebcdic-nl25 (and CMake equivalent) for the alternate NL encoding.
Add support for PCRE_STUDY_EXTRA_NEEDED.
Improve extended grapheme clusters using a bit table.
Upgrade \X to match an extended grapheme cluster
Fix patterns that incorrectly set "anchored" or "start of line" for .* inside atomic parentheses or when *PRUNE or *SKIP is present.
Apply character value checks to \u.... in JavaScript mode, for compatibility
with \x{....} in non-JavaScript mode.
Document update for 8.31-RC1 test release.
Check for overlong name in (*MARK) etc.
(COMMIT*) is now supported by the JIT compiler
Applied Graycode's patch to use heap stack frames more efficiently.
Add support for PCRE_INFO_MAXLOOKBEHIND.
(*MARK) support, set_SOM optimization and other fixes in JIT
Improved \X and back reference partial matching
Partial matching support is added to the JIT compiler
fix local symbol issues in pcre_printint.c
JIT test prints cpu info

Add pcre16 prefix to 16 bit structs
add pcre16_callout_block and pcre16_extra
Tidy compile-time error messages for 16-bit.
Merging all the changes from the pcre16 branch into the trunk.
Rolled back trunk to r755 to prepare for merging the 16-bit branch.
Source tidies for 8.21-RC1
Preserve the size of JIT compiled code. Add PCRE_INFO_JITSIZE and use it for the /M option in pcretest.
Expand compile workspace for very many forward references. This ups the limit by a factor of 100.
Update *MARK handling to be more like Perl.
Test for workspace overflow with forward reference data.
Disallow \N in character classes, for Perl compatibility.
Support \C in lookbehinds and DFA matching when not in UTF-8 mode.
Fixed several items that were being incorrectly rejected as "not fixed length" in lookbehinds.
Source tidies for 8.20-RC3.
Revert handling of atomic groups that do not include captures to the old way of handling, thus reducing stack usage.
Make (*THEN) work as in Perl in subpatterns that do not contain | alternatives.
File tidies for 8.20-RC2 release.
Restore tail-recursion optimizations when no (*THEN) in pattern.
Final source and document tidies for 8.20-RC1.
Adjust JIT limit code; make JIT test return 1 if not successful.
Commit all the changes for JIT support, but without any documentation yet.
Documentation and general text tidies in preparation for test release.
Avoid false positive for infinite recursion by not checking conditionals at compile time, but add tests at runtime that also catch infinite mutual recursion.
Permit quantifiers on parenthesized assertions.
Fix isolated \k bug.
Re-do atomic group processing to fix backtrack capture bugs. Recursion is also re-worked.
Fix problem with the interaction of (*ACCEPT) in an assertion with PCRE_NOTEMPTY.
Fix two study bugs concerned with minimum subject lengths; add features to pcretest so that all tests can be run with or without study; adjust tests so that this happens.
Refactoring to reduce stack usage for possessively quantified subpatterns. Also fixed a number of bugs related to repeated subpatterns. Some further tidies consequent on the removal of OP_OPT are also in this patch.
Remove OP_OPT by handling /i and /m entirely at compile time. Fixes bug with patterns like /(?i:([^b]))(?1)/, where the /i option was mishandled.
Pass back detailed info when UTF-8 check fails at runtime.
Fix small typos in pcre_internal.h
Tidies of documenation and code while preparing for release.
Added support for (*NO_START_OPT)
Give error if \c is followed by a byte > 127 (in ASCII/UTF-8 modes).
Remove loops from GETCHAR etc. macros.
Fix problem with (*THEN) not backing up far enough.
Prepare for release candidate.
Fix crash for property test in non-UTF-8 mode.
Added PCRE_UCP and related stuff to make \w etc use Unicode properties.
Add new special properties Xan, Xps, Xsp, Xwd to help with \w etc.

Tidy up, remove trailing spaces, etc. for 8.00-RC1.
Fix problems with conditional references to duplicate named subpatterns.
Allow duplicate names for same-numbered groups; forbid different names.
Added lower bound length-finding to pcre_study() and use it when matching; make the value available via pcre_fullinfo(); also fixed bugs connected with pcre_study() in pcre_dfa_exec().
Allow fixed-length subroutine calls in lookbehinds.
Capture data when (*ACCEPT) is inside capturing parentheses.
Correct returned capture count after recursion has matched more than outer.
