A new flag is set, when property checks are present in an XCLASS.
Final file tidies for 8.34.
Fix internal error for XCLASS in 16/32-bit non-UCP versions with heap recursion, and get rid of some compiler warnings when UCP is not configured.
Add support for [[:<:]] and [[:>:]] as a transition aid.
Source tidies for 8.34-RC1.
Rename the (as yet unreleased) PCRE_NO_AUTO_POSSESSIFY option to PCRE_NO_AUTO_POSSESS - no need to be so long - and to match (*NO_AUTO_POSSESS).
In /x mode, allow white space before a possessive + character.
Add (*NO_AUTO_POSSESS) and document interaction between auto-possessification and callouts.
Require group names to start with a non-digit.
Allow quantifiers on (?!) so as to be the same as other assertions.
Give errors for [A-\d] and [a-[:digit:]] etc.
Implement compile-time nested parentheses limit, specified at build time.
Update POSIX class handling in UCP mode.
Guard the call of check_char_prop since it does not exists when UCP is disabled.
Allow auto-possessify to check more complex bracketed expressions.
Auto-possessify OP_CLASS and some other bugfixes.
Auto-possessifying now supports property comparison with zero repeat quantifiers.
Explicit possessive quantifiers now use the new opcodes. Fixed an infelicity with EXACT in caseless mode.
More auto-possessification additions, using possessive class repeats. These are not yet used for explicit possessification.
Add U+0085 and U+180E to what \s matches in UCP mode, to match Perl.
+1 is not needed for XCLASS as well.
Further auto-possessification patch.
Fix \o{...} to accept characters between 0x80000000 and 0xffffffff
The 32-bit library in non-UTF-32 mode can accept any 32-bit character, not
just up to 0x7fffffff.
Fix auto-callout with PCRE_UCP, which was compiling rubbish.
Add \o{} and tidy up \x{} handling. Minor update to RunTest.
Update \8 and \9 handling to match most recent Perl.
Refactor named group handling for conditional tests.
Add VT to the set of characters recognized as white space.
Refactored auto-possessification code.
Make back references to duplicated named subpatterns more like Perl.
Fix typo in comment.
Refactor the code for creating the name/number table.
Fix incorrect "first data item" recorded for an assertion condition.
Implement PCRE_INFO_MATCH_EMPTY and fix 2 bugs concerned with scanning for empty string matching.
Fix spelling mistakes in comments.
Code (but not yet documentation) for *LIMIT_MATCH and *LIMIT_RECURSION.
Implement PCRE_NEVER_UTF
Fix open parens in MAKE/SKIP/PRUNE/THEN name bug.
Allow callout before assertion condition in a conditional group.
Make \A record a lookbehind value of 1.
Fix some Microsoft compiler warnings.
Remove commented code that has been obsolete since 8.00.
File tidies, preparing for 8.32-RC1.
Support (*UTF) in all libraries.
Remove unnecessary unsigned casts
Use CHAR_NULL in pcre_compile when checking for character zero.
valgrind: Mark excess code space as unaddressable When PCRE compiles a pattern, the required space is first estimated and this amount of memory is then allocated. For some patterns, the actually required code space is less than that, which means that the end of the code space is unused. This patch marks that region as unaddressable, so that valgrind will signal an error when it is accessed.
Refactor the solution of the unsigned overflow.
Fix overflow by unsigned conversion Similar to rev 1146.
Get rid of compiler warnings from pcre_compile.c in all modes.
pcre32: Fix signed-unsigned compare
pcre32: Fix signed-unsigned compare
pcre32: Fix signed-unsigned compare
pcre32: Fix signed-unsigned compare
pcre32: Fix signed-unsigned compare
pcre32: Remove a stray comment
pcre32: Fix unused variable warnings Add ifdefs since these variables are unused on pcre32.
pcre32: Remove unnecessary ifdefing Just define HAS_EXTRALEN etc to 0. This reduces the amount of #ifdef COMPILE_PCRE32.
pcre32: More 32-bit cleanliness fixes
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 compile_branch
pcre32: compile: Fix signed/unsigned mismatch in check_auto_possessive
pcre32: compile: Fix signed/unsigned mismatch in check_posix_name
pcre32: compile: Fix signed/unsigned mismatch in adjust_recurse
pcre32: compile: Fix signed/unsigned mismatch in check_posix_syntax
pcre32: compile: Fix signed/unsigned mismatch in could_be_empty_branch
pcre32: compile: Fix signed/unsigned mismatch in find_recurse
pcre32: compile: Fix signed/unsigned mismatch in find_bracket
pcre32: compile: Fix signed/unsigned mismatch in find_fixedlength
pcre32: compile: Fix signed/unsigned mismatch in find_parens_sub
pcre32: compile: Fix signed/unsigned mismatch in read_repeat_counts
pcre32: compile: Fix signed/unsigned mismatch in get_ucp
pcre32: compile: Use uint32 to store characters in compile_branch Do this to preserve any 32-bit data character in 32-bit non-UTF-32 mode.
pcre32: compile: Use uint32 to store characters in check_auto_possessive Do this to preserve any 32-bit data character in 32-bit non-UTF-32 mode.
pcre32: compile: Return data character as uint32 from check_escape Do this to preserve any 32-bit data character in 32-bit non-UTF-32 mode.
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: Use uint32 in check_escape
Use pcre_uint32 for the data character in check_escape(), so that it
correctly parses \x{} with any 32-bit hex value in 32-bit non-UTF-32
mode.
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: compile: Fix \H and \V character ranges for pcre32 Go up to 0xffffffff, and move the tests to the split 16- and 32-bit tests because the output differs. TODO: these character ranges look rather odd for non-UTF mode... bug?
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.
Fix bugs in new caseless support code in the auto-possessifying function.
Case folding in JIT and removing unnecessary spaces
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.
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.
Fix patterns that incorrectly set "anchored" or "start of line" for .* inside atomic parentheses or when *PRUNE or *SKIP is present.
Source tidies for 8.31-RC2.
Apply character value checks to \u.... in JavaScript mode, for compatibility
with \x{....} in non-JavaScript mode.

Fix auto-possessify bugs for \s*\R and \S*R.
Add support for PCRE_INFO_MAXLOOKBEHIND.
Correct and tidy up comments relating to OP_NOT (no code changes).

Rolled back trunk to r755 to prepare for merging the 16-bit branch.
Renamed isnumber in pcre_compile to avoid a clash with ctype.h in Macs, and fixed a bug in fixed-length calculation for lookbehinds that would show up only in quite long subpatterns.
Computation of memory needed for the table of names of groups was giving an unnecessarily large value.
Source tidies for 8.21-RC1
Added (int) casts to reduce 64-bit warnings.

Minor code tidy.
Permit quantifiers on parenthesized assertions.
Document and comment tidies.
Fix isolated \k bug.
Fix unset variable bug introduced during recursion refactoring.
Remove atomic from single repeats; convert possessive atomic to possessive non-atomic (because they are the same).
