Thu Apr 10 14:00:00 2008 roAATTsuse.de
- added baselibs.conf file to build xxbit packages
for multilib support

Fri Feb 1 13:00:00 2008 crrodriguezAATTsuse.de
- update to version 7.6
- The main reason for having this release so soon after 7.5
is because it fixes a potential buffer overflow problem in pcre_compile()
when run in UTF-8 mode. In addition, the CMake configuration files have been brought up to date.

Sun Jan 13 13:00:00 2008 crrodriguezAATTsuse.de
- update version 7.5
1. Applied a patch from Craig: \"This patch makes it possible to \'ignore\'
values in parens when parsing an RE using the C++ wrapper.\"
2. Negative specials like \\S did not work in character classes in UTF-8 mode.
Characters greater than 255 were excluded from the class instead of being
included.
3. The same bug as (2) above applied to negated POSIX classes such as
[:^space:].
4. PCRECPP_STATIC was referenced in pcrecpp_internal.h, but nowhere was it
defined or documented. It seems to have been a typo for PCRE_STATIC, so
I have changed it.
5. The construct (?&) was not diagnosed as a syntax error (it referenced the
first named subpattern) and a construct such as (?&a) would reference the
first named subpattern whose name started with \"a\" (in other words, the
length check was missing). Both these problems are fixed. \"Subpattern name
expected\" is now given for (?&) (a zero-length name), and this patch also
makes it give the same error for \\k\'\' (previously it complained that that
was a reference to a non-existent subpattern).
6. The erroneous patterns (?+-a) and (?-+a) give different error messages;
this is right because (?- can be followed by option settings as well as by
digits. I have, however, made the messages clearer.
7. Patterns such as (?(1)a|b) (a pattern that contains fewer subpatterns
than the number used in the conditional) now cause a compile-time error.
This is actually not compatible with Perl, which accepts such patterns, but
treats the conditional as always being FALSE (as PCRE used to), but it
seems to me that giving a diagnostic is better.
8. Change \"alphameric\" to the more common word \"alphanumeric\" in comments
and messages.
9. Fix two occurrences of \"backslash\" in comments that should have been
\"backspace\".
10. Remove two redundant lines of code that can never be obeyed (their function
was moved elsewhere).
11. The program that makes PCRE\'s Unicode character property table had a bug
which caused it to generate incorrect table entries for sequences of
characters that have the same character type, but are in different scripts.
It amalgamated them into a single range, with the script of the first of
them. In other words, some characters were in the wrong script. There were
thirteen such cases, affecting characters in the following ranges:
U+002b0 - U+002c1
U+0060c - U+0060d
U+0061e - U+00612
U+0064b - U+0065e
U+0074d - U+0076d
U+01800 - U+01805
U+01d00 - U+01d77
U+01d9b - U+01dbf
U+0200b - U+0200f
U+030fc - U+030fe
U+03260 - U+0327f
U+0fb46 - U+0fbb1
U+10450 - U+1049d
12. The -o option (show only the matching part of a line) for pcregrep was not
compatible with GNU grep in that, if there was more than one match in a
line, it showed only the first of them. It now behaves in the same way as
GNU grep.
13. If the -o and -v options were combined for pcregrep, it printed a blank
line for every non-matching line. GNU grep prints nothing, and pcregrep now
does the same. The return code can be used to tell if there were any
non-matching lines.
14. Added --file-offsets and --line-offsets to pcregrep.
15. The pattern (?=something)(?R) was not being diagnosed as a potentially
infinitely looping recursion. The bug was that positive lookaheads were not
being skipped when checking for a possible empty match (negative lookaheads
and both kinds of lookbehind were skipped).
16. Fixed two typos in the Windows-only code in pcregrep.c, and moved the
inclusion of to before rather than after the definition of
INVALID_FILE_ATTRIBUTES (patch from David Byron).
17. Specifying a possessive quantifier with a specific limit for a Unicode
character property caused pcre_compile() to compile bad code, which led at
runtime to PCRE_ERROR_INTERNAL (-14). Examples of patterns that caused this
are: /\\p{Zl}{2,3}+/8 and /\\p{Cc}{2}+/8. It was the possessive \"+\" that
caused the error; without that there was no problem.
18. Added --enable-pcregrep-libz and --enable-pcregrep-libbz2.
19. Added --enable-pcretest-libreadline.
20. In pcrecpp.cc, the variable \'count\' was incremented twice in
RE::GlobalReplace(). As a result, the number of replacements returned was
double what it should be. I removed one of the increments, but Craig sent a
later patch that removed the other one (the right fix) and added unit tests
that check the return values (which was not done before).
21. Several CMake things:
(1) Arranged that, when cmake is used on Unix, the libraries end up with
the names libpcre and libpcreposix, not just pcre and pcreposix.
(2) The above change means that pcretest and pcregrep are now correctly
linked with the newly-built libraries, not previously installed ones.
(3) Added PCRE_SUPPORT_LIBREADLINE, PCRE_SUPPORT_LIBZ, PCRE_SUPPORT_LIBBZ2.
22. In UTF-8 mode, with newline set to \"any\", a pattern such as .
*a.
*=.b.
*
crashed when matching a string such as a\\x{2029}b (note that \\x{2029} is a
UTF-8 newline character). The key issue is that the pattern starts .
*;
this means that the match must be either at the beginning, or after a
newline. The bug was in the code for advancing after a failed match and
checking that the new position followed a newline. It was not taking
account of UTF-8 characters correctly.
23. PCRE was behaving differently from Perl in the way it recognized POSIX
character classes. PCRE was not treating the sequence [:...:] as a
character class unless the ... were all letters. Perl, however, seems to
allow any characters between [: and :], though of course it rejects as
unknown any \"names\" that contain non-letters, because all the known class
names consist only of letters. Thus, Perl gives an error for [[:1234:]],
for example, whereas PCRE did not - it did not recognize a POSIX character
class. This seemed a bit dangerous, so the code has been changed to be
closer to Perl. The behaviour is not identical to Perl, because PCRE will
diagnose an unknown class for, for example, [[:l\\ower:]] where Perl will
treat it as [[:lower:]]. However, PCRE does now give \"unknown\" errors where
Perl does, and where it didn\'t before.
24. Rewrite so as to remove the single use of %n from pcregrep because in some
Windows environments %n is disabled by default.

Tue Nov 6 13:00:00 2007 crrodriguezAATTsuse.de
- update to version 7.4, since version 7.2, more than 40 bugs were fixed
including multiple vulnerabilities [#325921] . The list of changes is too long
to mention here, see changelog.txt for details.

Wed Aug 8 14:00:00 2007 msAATTsuse.de
- added fix to run ldconfig for libpcre
*, Thanks to
Cristian Rodriguez who provided
the patch (#298291)

Mon Jul 23 14:00:00 2007 msAATTsuse.de
- 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 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.

Tue May 1 14:00:00 2007 msAATTsuse.de
- added --enable-unicode-properties configure option to support
UTF-8 character strings in \\P, \\p, and \\X (#269749)

Mon Apr 30 14:00:00 2007 trennAATTsuse.de
- corrected assert compile error

Wed Apr 25 14:00:00 2007 msAATTsuse.de
- 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 \
of a subject such as \"A\\r\
B\".
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\
.
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 was matched against the string
\"abc\\r\
\\r\
\", 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.

Fri Feb 9 13:00:00 2007 msAATTsuse.de
- fixed wrong usage of assert() call

Tue Jan 9 13:00:00 2007 msAATTsuse.de
- fixed build for all architectures

Mon Jan 8 13:00:00 2007 msAATTsuse.de
- 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.

Sat Oct 28 14:00:00 2006 meissnerAATTsuse.de
- CXXFLAGS needs RPM_OPT_FLAGS too.

Mon Jul 10 14:00:00 2006 msAATTsuse.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\".
