Update to 6.5:

Version 6.5 01-Feb-06
---------------------

 1. When using the partial match feature with pcre_dfa_exec(), it was not
    anchoring the second and subsequent partial matches at the new starting
    point. This could lead to incorrect results. For example, with the pattern
    /1234/, partially matching against "123" and then "a4" gave a match.

 2. Changes to pcregrep:

    (a) All non-match returns from pcre_exec() were being treated as failures
        to match the line. Now, unless the error is PCRE_ERROR_NOMATCH, an
        error message is output. Some extra information is given for the
        PCRE_ERROR_MATCHLIMIT and PCRE_ERROR_RECURSIONLIMIT errors, which are
        probably the only errors that are likely to be caused by users (by
        specifying a regex that has nested indefinite repeats, for instance).
        If there are more than 20 of these errors, pcregrep is abandoned.

    (b) A binary zero was treated as data while matching, but terminated the
        output line if it was written out. This has been fixed: binary zeroes
        are now no different to any other data bytes.

    (c) Whichever of the LC_ALL or LC_CTYPE environment variables is set is
        used to set a locale for matching. The --locale=xxxx long option has
        been added (no short equivalent) to specify a locale explicitly on the
        pcregrep command, overriding the environment variables.

    (d) When -B was used with -n, some line numbers in the output were one less
        than they should have been.

    (e) Added the -o (--only-matching) option.

    (f) If -A or -C was used with -c (count only), some lines of context were
        accidentally printed for the final match.

    (g) Added the -H (--with-filename) option.

    (h) The combination of options -rh failed to suppress file names for files
        that were found from directory arguments.

    (i) Added the -D (--devices) and -d (--directories) options.

    (j) Added the -F (--fixed-strings) option.

    (k) Allow "-" to be used as a file name for -f as well as for a data file.

    (l) Added the --colo(u)r option.

    (m) Added Jeffrey Friedl's -S testing option, but within #ifdefs so that it
        is not present by default.

 3. A nasty bug was discovered in the handling of recursive patterns, that is,
    items such as (?R) or (?1), when the recursion could match a number of
    alternatives. If it matched one of the alternatives, but subsequently,
    outside the recursion, there was a failure, the code tried to back up into
    the recursion. However, because of the way PCRE is implemented, this is not
    possible, and the result was an incorrect result from the match.

    In order to prevent this happening, the specification of recursion has
    been changed so that all such subpatterns are automatically treated as
    atomic groups. Thus, for example, (?R) is treated as if it were (?>(?R)).

 4. I had overlooked the fact that, in some locales, there are characters for
    which isalpha() is true but neither isupper() nor islower() are true. In
    the fr_FR locale, for instance, the \xAA and \xBA characters (ordmasculine
    and ordfeminine) are like this. This affected the treatment of \w and \W
    when they appeared in character classes, but not when they appeared outside
    a character class. The bit map for "word" characters is now created
    separately from the results of isalnum() instead of just taking it from the
    upper, lower, and digit maps. (Plus the underscore character, of course.)

 5. The above bug also affected the handling of POSIX character classes such as
    [[:alpha:]] and [[:alnum:]]. These do not have their own bit maps in PCRE's
    permanent tables. Instead, the bit maps for such a class were previously
    created as the appropriate unions of the upper, lower, and digit bitmaps.
    Now they are created by subtraction from the [[:word:]] class, which has
    its own bitmap.

 6. The [[:blank:]] character class matches horizontal, but not vertical space.
    It is created by subtracting the vertical space characters (\x09, \x0a,
    \x0b, \x0c) from the [[:space:]] bitmap. Previously, however, the
    subtraction was done in the overall bitmap for a character class, meaning
    that a class such as [\x0c[:blank:]] was incorrect because \x0c would not
    be recognized. This bug has been fixed.

 7. Patches from the folks at Google:

      (a) pcrecpp.cc: "to handle a corner case that may or may not happen in
      real life, but is still worth protecting against".

      (b) pcrecpp.cc: "corrects a bug when negative radixes are used with
      regular expressions".

      (c) pcre_scanner.cc: avoid use of std::count() because not all systems
      have it.

      (d) Split off pcrecpparg.h from pcrecpp.h and had the former built by
      "configure" and the latter not, in order to fix a problem somebody had
      with compiling the Arg class on HP-UX.

      (e) Improve the error-handling of the C++ wrapper a little bit.

      (f) New tests for checking recursion limiting.

 8. The pcre_memmove() function, which is used only if the environment does not
    have a standard memmove() function (and is therefore rarely compiled),
    contained two bugs: (a) use of int instead of size_t, and (b) it was not
    returning a result (though PCRE never actually uses the result).

 9. In the POSIX regexec() interface, if nmatch is specified as a ridiculously
    large number - greater than INT_MAX/(3*sizeof(int)) - REG_ESPACE is
    returned instead of calling malloc() with an overflowing number that would
    most likely cause subsequent chaos.

10. The debugging option of pcretest was not showing the NO_AUTO_CAPTURE flag.

11. The POSIX flag REG_NOSUB is now supported. When a pattern that was compiled
    with this option is matched, the nmatch and pmatch options of regexec() are
    ignored.

12. Added REG_UTF8 to the POSIX interface. This is not defined by POSIX, but is
    provided in case anyone wants to the the POSIX interface with UTF-8
    strings.

13. Added CXXLDFLAGS to the Makefile parameters to provide settings only on the
    C++ linking (needed for some HP-UX environments).

14. Avoid compiler warnings in get_ucpname() when compiled without UCP support
    (unused parameter) and in the pcre_printint() function (omitted "default"
    switch label when the default is to do nothing).

15. Added some code to make it possible, when PCRE is compiled as a C++
    library, to replace subject pointers for pcre_exec() with a smart pointer
    class, thus making it possible to process discontinuous strings.

16. The two macros PCRE_EXPORT and PCRE_DATA_SCOPE are confusing, and perform
    much the same function. They were added by different people who were trying
    to make PCRE easy to compile on non-Unix systems. It has been suggested
    that PCRE_EXPORT be abolished now that there is more automatic apparatus
    for compiling on Windows systems. I have therefore replaced it with
    PCRE_DATA_SCOPE. This is set automatically for Windows; if not set it
    defaults to "extern" for C or "extern C" for C++, which works fine on
    Unix-like systems. It is now possible to override the value of PCRE_DATA_
    SCOPE with something explicit in config.h. In addition:

    (a) pcreposix.h still had just "extern" instead of either of these macros;
        I have replaced it with PCRE_DATA_SCOPE.

    (b) Functions such as _pcre_xclass(), which are internal to the library,
        but external in the C sense, all had PCRE_EXPORT in their definitions.
        This is apparently wrong for the Windows case, so I have removed it.
        (It makes no difference on Unix-like systems.)

17. Added a new limit, MATCH_LIMIT_RECURSION, which limits the depth of nesting
    of recursive calls to match(). This is different to MATCH_LIMIT because
    that limits the total number of calls to match(), not all of which increase
    the depth of recursion. Limiting the recursion depth limits the amount of
    stack (or heap if NO_RECURSE is set) that is used. The default can be set
    when PCRE is compiled, and changed at run time. A patch from Google adds
    this functionality to the C++ interface.

18. Changes to the handling of Unicode character properties:

    (a) Updated the table to Unicode 4.1.0.

    (b) Recognize characters that are not in the table as "Cn" (undefined).

    (c) I revised the way the table is implemented to a much improved format
        which includes recognition of ranges. It now supports the ranges that
        are defined in UnicodeData.txt, and it also amalgamates other
        characters into ranges. This has reduced the number of entries in the
        table from around 16,000 to around 3,000, thus reducing its size
        considerably. I realized I did not need to use a tree structure after
        all - a binary chop search is just as efficient. Having reduced the
        number of entries, I extended their size from 6 bytes to 8 bytes to
        allow for more data.

    (d) Added support for Unicode script names via properties such as \p{Han}.

19. In UTF-8 mode, a backslash followed by a non-Ascii character was not
    matching that character.

20. When matching a repeated Unicode property with a minimum greater than zero,
    (for example \pL{2,}), PCRE could look past the end of the subject if it
    reached it while seeking the minimum number of characters. This could
    happen only if some of the characters were more than one byte long, because
    there is a check for at least the minimum number of bytes.

21. Refactored the implementation of \p and \P so as to be more general, to
    allow for more different types of property in future. This has changed the
    compiled form incompatibly. Anybody with saved compiled patterns that use
    \p or \P will have to recompile them.

22. Added "Any" and "L&" to the supported property types.

23. Recognize \x{...} as a code point specifier, even when not in UTF-8 mode,
    but give a compile time error if the value is greater than 0xff.

24. The man pages for pcrepartial, pcreprecompile, and pcre_compile2 were
    accidentally not being installed or uninstalled.

25. The pcre.h file was built from pcre.h.in, but the only changes that were
    made were to insert the current release number. This seemed silly, because
    it made things harder for people building PCRE on systems that don't run
    "configure". I have turned pcre.h into a distributed file, no longer built
    by "configure", with the version identification directly included. There is
    no longer a pcre.h.in file.

    However, this change necessitated a change to the pcre-config script as
    well. It is built from pcre-config.in, and one of the substitutions was the
    release number. I have updated configure.ac so that ./configure now finds
    the release number by grepping pcre.h.

26. Added the ability to run the tests under valgrind.
