Changes 8.11:
A number of bugs in the library and in pcregrep have been fixed. As always, see
ChangeLog for details. The following are the non-bug-fix changes:
. Added --match-limit and --recursion-limit to pcregrep.
. Added an optional parentheses number to the -o and --only-matching options
  of pcregrep.
. Changed the way PCRE_PARTIAL_HARD affects the matching of $, \z, \Z, \b, and
  \B.
. Added PCRE_ERROR_SHORTUTF8 to make it possible to distinguish between a
  bad UTF-8 sequence and one that is incomplete when using PCRE_PARTIAL_HARD.
. Recognize (*NO_START_OPT) at the start of a pattern to set the PCRE_NO_
  START_OPTIMIZE option, which is now allowed at compile time

Update to 8.10:

Release 8.10 25-Jun-2010
------------------------

There are two major additions: support for (*MARK) and friends, and the option
PCRE_UCP, which changes the behaviour of \b, \d, \s, and \w (and their
opposites) so that they make use of Unicode properties. There are also a number
of lesser new features, and several bugs have been fixed. A new option,
--line-buffered, has been added to pcregrep, for use when it is connected to
pipes.

Update to 8.00:

Release 8.00 19-Oct-09
----------------------

Bugs have been fixed in the library and in pcregrep. There are also some
enhancements. Restrictions on patterns used for partial matching have been
removed, extra information is given for partial matches, the partial matching
process has been improved, and an option to make a partial match override a
full match is available. The "study" process has been enhanced by finding a
lower bound matching length. Groups with duplicate numbers may now have
duplicated names without the use of PCRE_DUPNAMES. However, they may not have
different names. The documentation has been revised to reflect these changes.
The version number has been expanded to 3 digits as it is clear that the rate
of change is not slowing down.

Version 7.9 11-Apr-09
---------------------

1.  When building with support for bzlib/zlib (pcregrep) and/or readline
    (pcretest), all targets were linked against these libraries. This included
    libpcre, libpcreposix, and libpcrecpp, even though they do not use these
    libraries. This caused unwanted dependencies to be created. This problem
    has been fixed, and now only pcregrep is linked with bzlib/zlib and only
    pcretest is linked with readline.

2.  The "typedef int BOOL" in pcre_internal.h that was included inside the
    "#ifndef FALSE" condition by an earlier change (probably 7.8/18) \ 
has been
    moved outside it again, because FALSE and TRUE are already defined in AIX,
    but BOOL is not.

3.  The pcre_config() function was treating the PCRE_MATCH_LIMIT and
    PCRE_MATCH_LIMIT_RECURSION values as ints, when they should be long ints.

4.  The pcregrep documentation said spaces were inserted as well as colons (or
    hyphens) following file names and line numbers when outputting matching
    lines. This is not true; no spaces are inserted. I have also clarified the
    wording for the --colour (or --color) option.

5.  In pcregrep, when --colour was used with -o, the list of matching strings
    was not coloured; this is different to GNU grep, so I have changed it to be
    the same.

6.  When --colo(u)r was used in pcregrep, only the first matching substring in
    each matching line was coloured. Now it goes on to look for further matches
    of any of the test patterns, which is the same behaviour as GNU grep.

7.  A pattern that could match an empty string could cause pcregrep to loop; it
    doesn't make sense to accept an empty string match in pcregrep, so I have
    locked it out (using PCRE's PCRE_NOTEMPTY option). By experiment, this
    seems to be how GNU grep behaves.

8.  The pattern (?(?=.*b)b|^) was incorrectly compiled as "match must be at
    start or after a newline", because the conditional assertion was not being
    correctly handled. The rule now is that both the assertion and what follows
    in the first alternative must satisfy the test.

9.  If auto-callout was enabled in a pattern with a conditional group whose
    condition was an assertion, PCRE could crash during matching, both with
    pcre_exec() and pcre_dfa_exec().

10. The PCRE_DOLLAR_ENDONLY option was not working when pcre_dfa_exec() was
    used for matching.

11. Unicode property support in character classes was not working for
    characters (bytes) greater than 127 when not in UTF-8 mode.

12. Added the -M command line option to pcretest.

14. Added the non-standard REG_NOTEMPTY option to the POSIX interface.

15. Added the PCRE_NO_START_OPTIMIZE match-time option.

16. Added comments and documentation about mis-use of no_arg in the C++
    wrapper.

17. Implemented support for UTF-8 encoding in EBCDIC environments, a patch
    from Martin Jerabek that uses macro names for all relevant character and
    string constants.

18. Added to pcre_internal.h two configuration checks: (a) If both EBCDIC and
    SUPPORT_UTF8 are set, give an error; (b) If SUPPORT_UCP is set without
    SUPPORT_UTF8, define SUPPORT_UTF8. The "configure" script handles \ 
both of
    these, but not everybody uses configure.

19. A conditional group that had only one branch was not being correctly
    recognized as an item that could match an empty string. This meant that an
    enclosing group might also not be so recognized, causing infinite looping
    (and probably a segfault) for patterns such as \ 
^"((?(?=[a])[^"])|b)*"$
    with the subject "ab", where knowledge that the repeated group can \ 
match
    nothing is needed in order to break the loop.

20. If a pattern that was compiled with callouts was matched using pcre_dfa_
    exec(), but without supplying a callout function, matching went wrong.

21. If PCRE_ERROR_MATCHLIMIT occurred during a recursion, there was a memory
    leak if the size of the offset vector was greater than 30. When the vector
    is smaller, the saved offsets during recursion go onto a local stack
    vector, but for larger vectors malloc() is used. It was failing to free
    when the recursion yielded PCRE_ERROR_MATCH_LIMIT (or any other \ 
"abnormal"
    error, in fact).

22. There was a missing #ifdef SUPPORT_UTF8 round one of the variables in the
    heapframe that is used only when UTF-8 support is enabled. This caused no
    problem, but was untidy.

23. Steven Van Ingelgem's patch to CMakeLists.txt to change the name
    CMAKE_BINARY_DIR to PROJECT_BINARY_DIR so that it works when PCRE is
    included within another project.

24. Steven Van Ingelgem's patches to add more options to the CMake support,
    slightly modified by me:

      (a) PCRE_BUILD_TESTS can be set OFF not to build the tests, including
          not building pcregrep.

      (b) PCRE_BUILD_PCREGREP can be see OFF not to build pcregrep, but only
          if PCRE_BUILD_TESTS is also set OFF, because the tests use pcregrep.

25. Forward references, both numeric and by name, in patterns that made use of
    duplicate group numbers, could behave incorrectly or give incorrect errors,
    because when scanning forward to find the reference group, PCRE was not
    taking into account the duplicate group numbers. A pattern such as
    ^X(?3)(a)(?|(b)|(q))(Y) is an example.

26. Changed a few more instances of "const unsigned char *" to USPTR, \ 
making
    the feature of a custom pointer more persuasive (as requested by a user).

27. Wrapped the definitions of fileno and isatty for Windows, which appear in
    pcretest.c, inside #ifndefs, because it seems they are sometimes already
    pre-defined.

28. Added support for (*UTF8) at the start of a pattern.

29. Arrange for flags added by the "release type" setting in CMake to \ 
be shown
    in the configuration summary.

Log message:
Simply and speed up buildlink3.mk files and processing.
This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.

Update to 7.8:

Version 7.8 05-Sep-08
---------------------

1.  Replaced UCP searching code with optimized version as implemented for Ad
    Muncher (http://www.admuncher.com/) by Peter Kankowski. This uses a two-
    stage table and inline lookup instead of a function, giving speed ups of 2
    to 5 times on some simple patterns that I tested. Permission was given to
    distribute the MultiStage2.py script that generates the tables (it's not in
    the tarball, but is in the Subversion repository).

2.  Updated the Unicode datatables to Unicode 5.1.0. This adds yet more
    scripts.

3.  Change 12 for 7.7 introduced a bug in pcre_study() when a pattern contained
    a group with a zero qualifier. The result of the study could be incorrect,
    or the function might crash, depending on the pattern.

4.  Caseless matching was not working for non-ASCII characters in back
    references. For example, /(\x{de})\1/8i was not matching \x{de}\x{fe}.
    It now works when Unicode Property Support is available.

5.  In pcretest, an escape such as \x{de} in the data was always generating
    a UTF-8 string, even in non-UTF-8 mode. Now it generates a single byte in
    non-UTF-8 mode. If the value is greater than 255, it gives a warning about
    truncation.

6.  Minor bugfix in pcrecpp.cc (change "" == ... to NULL == ...).

7.  Added two (int) casts to pcregrep when printing the difference of two
    pointers, in case they are 64-bit values.

8.  Added comments about Mac OS X stack usage to the pcrestack man page and to
    test 2 if it fails.

9.  Added PCRE_CALL_CONVENTION just before the names of all exported functions,
    and a #define of that name to empty if it is not externally set. This is to
    allow users of MSVC to set it if necessary.

10. The PCRE_EXP_DEFN macro which precedes exported functions was missing from
    the convenience functions in the pcre_get.c source file.

11. An option change at the start of a pattern that had top-level alternatives
    could cause overwriting and/or a crash. This command provoked a crash in
    some environments:

      printf "/(?i)[\xc3\xa9\xc3\xbd]|[\xc3\xa9\xc3\xbdA]/8\n" | pcretest

    This potential security problem was recorded as CVE-2008-2371.

12. For a pattern where the match had to start at the beginning or immediately
    after a newline (e.g /.*anything/ without the DOTALL flag), pcre_exec() and
    pcre_dfa_exec() could read past the end of the passed subject if there was
    no match. To help with detecting such bugs (e.g. with valgrind), I modified
    pcretest so that it places the subject at the end of its malloc-ed buffer.

13. The change to pcretest in 12 above threw up a couple more cases when pcre_
    exec() might read past the end of the data buffer in UTF-8 mode.

14. A similar bug to 7.3/2 existed when the PCRE_FIRSTLINE option was set and
    the data contained the byte 0x85 as part of a UTF-8 character within its
    first line. This applied both to normal and DFA matching.

15. Lazy qualifiers were not working in some cases in UTF-8 mode. For example,
    /^[^d]*?$/8 failed to match "abc".

16. Added a missing copyright notice to pcrecpp_internal.h.

17. Make it more clear in the documentation that values returned from
    pcre_exec() in ovector are byte offsets, not character counts.

18. Tidied a few places to stop certain compilers from issuing warnings.

19. Updated the Virtual Pascal + BCC files to compile the latest v7.7, as
    supplied by Stefan Weber. I made a further small update for 7.8 because
    there is a change of source arrangements: the pcre_searchfuncs.c module is
    replaced by pcre_ucd.c.
