- update to version 7.2, fixes bug: (#293752)
- Changes from 7.1 to 7.2

 1. If the fr_FR locale cannot be found for test 3, try the "french" locale,
    which is apparently normally available under Windows.

 2. Re-jig the pcregrep tests with different newline settings in an attempt
    to make them independent of the local environment's newline setting.

 3. Add code to configure.ac to remove -g from the CFLAGS default settings.

 4. Some of the "internals" tests were previously cut out when the link size
    was not 2, because the output contained actual offsets. The recent new
    "Z" feature of pcretest means that these can be cut out, making the tests
    usable with all link sizes.

 5. Implemented Stan Switzer's goto replacement for longjmp() when not using
    stack recursion. This gives a massive performance boost under BSD, but just
    a small improvement under Linux. However, it saves one field in the frame
    in all cases.

 6. Added more features from the forthcoming Perl 5.10:

    (a) (?-n) (where n is a string of digits) is a relative subroutine or
        recursion call. It refers to the nth most recently opened parentheses.

    (b) (?+n) is also a relative subroutine call; it refers to the nth next
        to be opened parentheses.

    (c) Conditions that refer to capturing parentheses can be specified
        relatively, for example, (?(-2)... or (?(+3)...

    (d) \K resets the start of the current match so that everything before
        is not part of it.

    (e) \k{name} is synonymous with \k<name> and \k'name' (.NET compatible).

    (f) \g{name} is another synonym - part of Perl 5.10's unification of
        reference syntax.

    (g) (?| introduces a group in which the numbering of parentheses in each
        alternative starts with the same number.

    (h) \h, \H, \v, and \V match horizontal and vertical whitespace.

 7. Added two new calls to pcre_fullinfo(): PCRE_INFO_OKPARTIAL and
    PCRE_INFO_JCHANGED.

 8. A pattern such as  (.*(.)?)*  caused pcre_exec() to fail by either not
    terminating or by crashing. Diagnosed by Viktor Griph; it was in the code
    for detecting groups that can match an empty string.

 9. A pattern with a very large number of alternatives (more than several
    hundred) was running out of internal workspace during the pre-compile
    phase, where pcre_compile() figures out how much memory will be needed. A
    bit of new cunning has reduced the workspace needed for groups with
    alternatives. The 1000-alternative test pattern now uses 12 bytes of
    workspace instead of running out of the 4096 that are available.

10. Inserted some missing (unsigned int) casts to get rid of compiler warnings.

11. Applied patch from Google to remove an optimization that didn't quite work.
    The report of the bug said:

      pcrecpp::RE("a*").FullMatch("aaa") matches, while
      pcrecpp::RE("a*?").FullMatch("aaa") does not, and
      pcrecpp::RE("a*?\\z").FullMatch("aaa") does again.

12. If \p or \P was used in non-UTF-8 mode on a character greater than 127
    it matched the wrong number of bytes.

- added --enable-unicode-properties configure option to support
  UTF-8 character strings in \P, \p, and \X (#269749)

- update to pcre 7.1

 1. Applied Bob Rossi and Daniel G's patches to convert the build system to one
    that is more "standard", making use of automake and other Autotools. There
    is some re-arrangement of the files and adjustment of comments consequent
    on this.

 2. Part of the patch fixed a problem with the pcregrep tests. The test of -r
    for recursive directory scanning broke on some systems because the files
    are not scanned in any specific order and on different systems the order
    was different. A call to "sort" has been inserted into RunGrepTest for the
    approprate test as a short-term fix. In the longer term there may be an
    alternative.

 3. I had an email from Eric Raymond about problems translating some of PCRE's
    man pages to HTML (despite the fact that I distribute HTML pages, some
    people do their own conversions for various reasons). The problems
    concerned the use of low-level troff macros .br and .in. I have therefore
    removed all such uses from the man pages (some were redundant, some could
    be replaced by .nf/.fi pairs). The 132html script that I use to generate
    HTML has been updated to handle .nf/.fi and to complain if it encounters
    .br or .in.

 4. Updated comments in configure.ac that get placed in config.h.in and also
    arranged for config.h to be included in the distribution, with the name
    config.h.generic, for the benefit of those who have to compile without
    Autotools (compare pcre.h, which is now distributed as pcre.h.generic).

 5. Updated the support (such as it is) for Virtual Pascal, thanks to Stefan
    Weber: (1) pcre_internal.h was missing some function renames; (2) updated
    makevp.bat for the current PCRE, using the additional files
    makevp_c.txt, makevp_l.txt, and pcregexp.pas.

 6. A Windows user reported a minor discrepancy with test 2, which turned out
    to be caused by a trailing space on an input line that had got lost in his
    copy. The trailing space was an accident, so I've just removed it.

 7. Add -Wl,-R... flags in pcre-config.in for *BSD* systems, as I'm told
    that is needed.

 8. Mark ucp_table (in ucptable.h) and ucp_gentype (in pcre_ucp_searchfuncs.c)
    as "const" (a) because they are and (b) because it helps the PHP
    maintainers who have recently made a script to detect big data structures
    in the php code that should be moved to the .rodata section. I remembered
    to update Builducptable as well, so it won't revert if ucptable.h is ever
    re-created.

 9. Added some extra #ifdef SUPPORT_UTF8 conditionals into pcretest.c,
    pcre_printint.src, pcre_compile.c, pcre_study.c, and pcre_tables.c, in
    order to be able to cut out the UTF-8 tables in the latter when UTF-8
    support is not required. This saves 1.5-2K of code, which is important in
    some applications.

    Later: more #ifdefs are needed in pcre_ord2utf8.c and pcre_valid_utf8.c
    so as not to refer to the tables, even though these functions will never be
    called when UTF-8 support is disabled. Otherwise there are problems with a
    shared library.

10. Fixed two bugs in the emulated memmove() function in pcre_internal.h:

    (a) It was defining its arguments as char * instead of void *.

    (b) It was assuming that all moves were upwards in memory; this was true
        a long time ago when I wrote it, but is no longer the case.

    The emulated memove() is provided for those environments that have neither
    memmove() nor bcopy(). I didn't think anyone used it these days, but that
    is clearly not the case, as these two bugs were recently reported.

11. The script PrepareRelease is now distributed: it calls 132html, CleanTxt,
    and Detrail to create the HTML documentation, the .txt form of the man
    pages, and it removes trailing spaces from listed files. It also creates
    pcre.h.generic and config.h.generic from pcre.h and config.h. In the latter
    case, it wraps all the #defines with #ifndefs. This script should be run
    before "make dist".

12. Fixed two fairly obscure bugs concerned with quantified caseless matching
    with Unicode property support.

    (a) For a maximizing quantifier, if the two different cases of the
        character were of different lengths in their UTF-8 codings (there are
        some cases like this - I found 11), and the matching function had to
        back up over a mixture of the two cases, it incorrectly assumed they
        were both the same length.

    (b) When PCRE was configured to use the heap rather than the stack for
        recursion during matching, it was not correctly preserving the data for
        the other case of a UTF-8 character when checking ahead for a match
        while processing a minimizing repeat. If the check also involved
        matching a wide character, but failed, corruption could cause an
        erroneous result when trying to check for a repeat of the original
        character.

13. Some tidying changes to the testing mechanism:

    (a) The RunTest script now detects the internal link size and whether there
        is UTF-8 and UCP support by running ./pcretest -C instead of relying on
        values substituted by "configure". (The RunGrepTest script already did
        this for UTF-8.) The configure.ac script no longer substitutes the
        relevant variables.

    (b) The debugging options /B and /D in pcretest show the compiled bytecode
        with length and offset values. This means that the output is different
        for different internal link sizes. Test 2 is skipped for link sizes
        other than 2 because of this, bypassing the problem. Unfortunately,
        there was also a test in test 3 (the locale tests) that used /B and
        failed for link sizes other than 2. Rather than cut the whole test out,
        I have added a new /Z option to pcretest that replaces the length and
        offset values with spaces. This is now used to make test 3 independent
        of link size. (Test 2 will be tidied up later.)

14. If erroroffset was passed as NULL to pcre_compile, it provoked a
    segmentation fault instead of returning the appropriate error message.

15. In multiline mode when the newline sequence was set to "any", the pattern
    ^$ would give a match between the \r and \n of a subject such as "A\r\nB".
    This doesn't seem right; it now treats the CRLF combination as the line
    ending, and so does not match in that case. It's only a pattern such as ^$
    that would hit this one: something like ^ABC$ would have failed after \r
    and then tried again after \r\n.

16. Changed the comparison command for RunGrepTest from "diff -u" to "diff -ub"
    in an attempt to make files that differ only in their line terminators
    compare equal. This works on Linux.

17. Under certain error circumstances pcregrep might try to free random memory
    as it exited. This is now fixed, thanks to valgrind.

19. In pcretest, if the pattern /(?m)^$/g<any> was matched against the string
    "abc\r\n\r\n", it found an unwanted second match after the second \r. This
    was because its rules for how to advance for /g after matching an empty
    string at the end of a line did not allow for this case. They now check for
    it specially.

20. pcretest is supposed to handle patterns and data of any length, by
    extending its buffers when necessary. It was getting this wrong when the
    buffer for a data line had to be extended.

21. Added PCRE_NEWLINE_ANYCRLF which is like ANY, but matches only CR, LF, or
    CRLF as a newline sequence.

22. Code for handling Unicode properties in pcre_dfa_exec() wasn't being cut
    out by #ifdef SUPPORT_UCP. This did no harm, as it could never be used, but
    I have nevertheless tidied it up.

23. Added some casts to kill warnings from HP-UX ia64 compiler.

24. Added a man page for pcre-config.

- update to new version 7.0
  Changes: As well as a number of bugfixes, there has been a major
  refactoring of the compiling code, which makes it easier to add new
  features, including some new optimizations. A QuoteMeta function has been
  added to the C++ wrapper. There is now a mode in which all Unicode newline
  sequences are recognized. Support for the Perl 5.10 syntax for features
  that were previously in PCRE but not in Perl (named groups, possessive
  quantifiers) has been added.

Mon Jul 10 16:29:14 CEST 2006 - ms@suse.de

- update to new version 6.7
- finally removed evil configure patch
- When UTF-8 mode was not set, PCRE looped when compiling certain patterns
  containing an extended class (one that cannot be represented by a bitmap
  because it contains high-valued characters or Unicode property items, e.g.
  [\pZ]). Almost always one would set UTF-8 mode when processing such a
  pattern, but PCRE should not loop if you do not (it no longer does).
  [Detail: two cases were found: (a) a repeated subpattern containing an
  extended class; (b) a recursive reference to a subpattern that followed a
  previous extended class. It wasn't skipping over the extended class
  correctly when UTF-8 mode was not set.]
- Applied a patch from the folks at Google to pcrecpp.cc, to fix "another
  instance of the 'standard' template library not being so standard".
