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.
Document update for 8.31-RC1 test release.
Check for overlong name in (*MARK) etc.
Fix auto-possessifying bugs when PCRE_UCP is not set, but character tables specify characters in the range 127-255 are letters, spaces, etc.
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).
OP_NOT now supports any UTF character
fix local symbol issues in pcre_printint.c
Additional casts to avoid compiler warnings, originally from a MS compiler, but also given by gcc if you turn on enough warnings.
Source file tidies for 8.30-RC1 release; fix Makefile.am bugs for building symbolic links to man pages.
Add pcre16 prefix to 16 bit structs
Allow octal escapes up to \777 in 16-bit non-UTF mode.
Tidy compile-time error messages for 16-bit.
Typos in PrepareRelease; include 16-bit in make distcheck; fix RunTest and RunGrepTest when building in non-source directory; problem in pcretest when no UTF or 16-bit support; other tidies consequent on building a tarball.
Merging all the changes from the pcre16 branch into the trunk.
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.
Expand compile workspace for very many forward references. This ups the limit by a factor of 100.
Fix repeated forward reference needed character bug.
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.
Code tidies.
Fix problem with possessively repeated groups with minima greater than one.
Fix bad compiling of possessively repeated conditional subpattern.
Fixed several items that were being incorrectly rejected as "not fixed length" in lookbehinds.
Caseless matching of backreferences with fixed length repetitions was broken.
Small tidies, and documentation update for JavaScript \x, \u, \U support.
Correctly supporting \x and \u in JavaScript compatibility mode
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.
Comment correction and minor code improvement.
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.
Fix miscompile of /(*ACCEPT)a/, which thought a match had to start with "a".
Final source and document tidies for 8.20-RC1.
Get rid of unused variable compiler warnings when UTF-8 not supported.
Fix bug introduced by 8.13/37 concerning POSIX class recognition
Documentation and general text tidies in preparation for test release.
Allow all characters except closing parens in MARK:NAME etc.
Avoid false positive for infinite recursion by not checking conditionals at compile time, but add tests at runtime that also catch infinite mutual recursion.
Fix three compile-time bugs (Bugzilla #1123).
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).
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.
Tidy the API for _pcre_valid_utf8() to a more suitable form for a future public release. Also make -s in pcretest force a study for every regex.
Make pcre_study() more robust against update omissions; fix ONCE oversight.
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.
Tidies of documenation and code while preparing for release.
Fix internal error for recursive named back references.
Added support for (*NO_START_OPT)
Give error if \c is followed by a byte > 127 (in ASCII/UTF-8 modes).
Fix #-comment bugs in UTF-8 mode with PCRE_NEWLINE_ANY.
Fix \s bug in character classes (always removing VT).
Fix problem with (*THEN) not backing up far enough.
Tidyup for 8.10-RC2 test release.
Fix forward reference in the presence of (?#( (open parens in comment).
Prepare for release candidate.
One more (int) cast.
Extend auto-possessify to handle some Unicode properties.
