------------------------------------------------------------------- Wed May 11 09:21:09 UTC 2022 - Jason Sikes <jsikes@suse.com> - Added pcre-8.45-bsc1199232-unicode-property-matching.patch * bsc#1199232 * CVE-2022-1586 * Fixes unicode property matching issue ------------------------------------------------------------------- Tue Oct 19 05:22:21 UTC 2021 - Stephan Kulow <coolo@suse.com> - pcre 8.45 (the final release) * Fixed a small (*MARK) bug in the interpreter (Bugzilla #2771). - pcre 8.44 * Small patch to pcreposix.c to set the erroroffset field to -1 immediately after a successful compile, instead of at the start of matching to avoid a sanitizer complaint (regexec is supposed to be thread safe). * Check the size of the number after (?C as it is read, in order to avoid integer overflow. (bsc#1172974, CVE-2020-14155) * Tidy up left shifts to avoid sanitize warnings; also fix one NULL deference in pcretest. - pcre 8.43 * In a pattern such as /[^\x{100}-\x{ffff}]*[\x80-\xff]/ which has a repeated negative class with no characters less than 0x100 followed by a positive class with only characters less than 0x100, the first class was incorrectly being auto-possessified, causing incorrect match failures. * If the only branch in a conditional subpattern was anchored, the whole subpattern was treated as anchored, when it should not have been, since the assumed empty second branch cannot be anchored. Demonstrated by test patterns such as /(?(1)^())b/ or /(?(?=^))b/. * Fix subject buffer overread in JIT when UTF is disabled and \X or \R has a greater than 1 fixed quantifier. This issue was found by Yunho Kim. (bsc#1172973 CVE-2019-20838) * If a pattern started with a subroutine call that had a quantifier with a minimum of zero, an incorrect "match must start with this character" could be recorded. Example: /(?&xxx)*ABC(?<xxx>XYZ)/ would (incorrectly) expect 'A' to be the first character of a match. - pcre 8.42 * If a backreference with a minimum repeat count of zero was first in a pattern, apart from assertions, an incorrect first matching character could be recorded. For example, for the pattern /(?=(a))\1?b/, "b" was incorrectly set as the first character of a match. * Fix out-of-bounds read for partial matching of /./ against an empty string when the newline type is CRLF. * When matching using the the REG_STARTEND feature of the POSIX API with a non-zero starting offset, unset capturing groups with lower numbers than a group that did capture something were not being correctly returned as "unset" (that is, with offset values of -1). * Matching the pattern /(*UTF)\C[^\v]+\x80/ against an 8-bit string containing multi-code-unit characters caused bad behaviour and possibly a crash. This issue was fixed for other kinds of repeat in release 8.37 by change 38, but repeating character classes were overlooked. - pcre 8.41 * Fix a missing else in the JIT compiler (bsc#1025709 CVE-2017-6004) * A (?# style comment is now ignored between a basic quantifier and a following '+' or '?' (example: /X+(?#comment)?Y/. * Avoid use of a potentially overflowing buffer in pcregrep (patch by Petr Pisar). * In the 32-bit library in non-UTF mode, an attempt to find a Unicode property for a character with a code point greater than 0x10ffff (the Unicode maximum) caused a crash. (bsc#1030807 CVE-2017-7244) * The alternative matching function, pcre_dfa_exec() misbehaved if it encountered a character class with a possessive repeat, for example [a-f]{3}+. (bsc#1030066 CVE-2017-7186) * When pcretest called pcre_copy_substring() in 32-bit mode, it set the buffer length incorrectly, which could result in buffer overflow. (bsc#1030805 CVE-2017-7245, bsc#1030803 CVE-2017-7246) * Fix returned offsets from regexec() when REG_STARTEND is used with a starting offset greater than zero. - pcre 8.40 * Fix register overwite in JIT when SSE2 acceleration is enabled. * Ignore "show all captures" (/=) for DFA matching. * Fix JIT unaligned accesses on x86. Patch by Marc Mutz. * In any wide-character mode (8-bit UTF or any 16-bit or 32-bit mode), without PCRE_UCP set, a negative character type such as \D in a positive class should cause all characters greater than 255 to match, whatever else is in the class. There was a bug that caused this not to happen if a Unicode property item was added to such a class, for example [\D\P{Nd}] or [\W\pL]. * A pattern such as (?<RA>abc)(?(R)xyz) was incorrectly compiled such that the conditional was interpreted as a reference to capturing group 1 instead of a test for recursion. Any group whose name began with R was misinterpreted in this way. (The reference interpretation should only happen if the group's name is precisely "R".) * A number of bugs have been mended relating to match start-up optimizations when the first thing in a pattern is a positive lookahead. These all applied only when PCRE_NO_START_OPTIMIZE was *not* set: (a) A pattern such as (?=.*X)X$ was incorrectly optimized as if it needed both an initial 'X' and a following 'X'. (b) Some patterns starting with an assertion that started with .* were incorrectly optimized as having to match at the start of the subject or after a newline. There are cases where this is not true, for example, (?=.*[A-Z])(?=.{8,16})(?!.*[\s]) matches after the start in lines that start with spaces. Starting .* in an assertion is no longer taken as an indication of matching at the start (or after a newline). ------------------------------------------------------------------- Thu Oct 19 09:26:17 UTC 2017 - kstreitova@suse.com - add pcre-8.39-stack_frame_size_detection.patch to fix pcre stack frame size detection because modern compilers broke it by cloning and inlining pcre match() function [bsc#1058722] ------------------------------------------------------------------- Wed Oct 26 15:26:14 UTC 2016 - astieger@suse.com - Update to PCRE 8.39 FATE#320298 bsc#972127. This version fixes a number of vulnerabilities that affect pcre and applications using the libary when accepting untrusted input as regular expressions or as part thereof. Remote attackers could have caused the application to crash, disclose information or potentially execute arbitrary code. * CVE-2014-8964: pcre: heap buffer overflow (bsc#906574) * CVE-2015-2325: pcre: heap buffer overflow in compile_branch() (bsc#924960) * CVE-2015-3210 pcre: heap buffer overflow in pcre_compile2() / compile_regex() (bsc#933288) * CVE-2015-3217: pcre: PCRE Library Call Stack Overflow Vulnerability in match() (bsc#933878) * CVE-2015-5073: pcre: Library Heap Overflow Vulnerability in find_fixedlength() (bsc#936227) * bsc#942865: heap overflow in compile_regex() * CVE-2015-8380: pcre: heap overflow in pcre_exec (bsc#957566) * CVE-2015-2327: pcre: mishandling of patterns with backreferences (bsc#957567) * bsc#957598: various security issues fixed in pcre 8.37 and 8.38 release * CVE-2015-2328: pcre: mishandled recursion patterns (bsc#957600) * CVE-2016-1283: pcre: Heap buffer overflow in pcre_compile2 causes DoS (bsc#960837) * CVE-2016-3191: pcre: workspace overflow for (*ACCEPT) with deeply nested parentheses (bsc#971741) - These other changes are included: * JIT compiler improvements * performance improvements * The Unicode data tables have been updated to Unicode 7.0.0. ------------------------------------------------------------------- Thu Jun 13 16:20:10 UTC 2013 - jengelh@inai.de - Update to new upstream release 8.33 * The Just-In-Time compiler (JIT) now supports all pattern features, including callouts and the backtracking verbs. In addition, some bugs are fixed and there are minor performance enhancements. - More robust make install call. Provide signature verification files (avoid depending on gpg-offline due to bootstrap cycle). ------------------------------------------------------------------- Sat Jun 8 20:16:10 UTC 2013 - crrodriguez@opensuse.org - Ensure the PCRE library and tools are built with large file support in 32 bit archs. ------------------------------------------------------------------- Sun Jan 6 15:40:59 UTC 2013 - p.drouand@gmail.com - Update to 8.32 version: * There is now support for 32-bit character strings and UTF-32. Like the 16-bit support, this is done by compiling a separate 32-bit library. * \X now matches a Unicode extended grapheme cluster. * Case-independent matching of Unicode characters that have more than one "other case" now makes all three (or more) characters equivalent. This applies, for example, to Greek Sigma, which has two lowercase versions. * Unicode character properties are updated to Unicode 6.2.0. * The EBCDIC support, which had decayed, has had a spring clean. * A number of JIT optimizations have been added, which give faster JIT execution speed. In addition, a new direct interface to JIT execution is available. This bypasses some of the sanity checks of pcre_exec() to give a noticeable speed-up. * A number of issues in pcregrep have been fixed, making it more compatible with GNU grep. In particular, --exclude and --include (and variants) apply to all files now, not just those obtained from scanning a directory recursively. In Windows environments, the default action for directories is now "skip" instead of "read" (which provokes an error). * If the --only-matching (-o) option in pcregrep is specified multiple times, each one causes appropriate output. For example, -o1 -o2 outputs the substrings matched by the 1st and 2nd capturing parentheses. A separating string can be specified by --om-separator (default empty). * When PCRE is built via Autotools using a version of gcc that has the "visibility" feature, it is used to hide internal library functions that are not part of the public API. - updated and versionned pcre-visibility.patch to svn trunk * Modifications on configure.ac and makefile have been merged on upstream release ------------------------------------------------------------------- Fri Nov 23 19:13:09 UTC 2012 - jengelh@inai.de - Update package descriptions about the differences between the PCRE library subpackages. ------------------------------------------------------------------- Wed Nov 7 13:35:35 UTC 2012 - cgiboudeaux@gmx.com - Use the --enable-pcre16 configure flag.

There are no changes to the code of the library. - Update to version 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 ------------------------------------------------------------------- Sat Oct 30 02:15:06 UTC 2010 - cristian.rodriguez@opensuse.org - Support GCC visibility, symbol clashes no more. ------------------------------------------------------------------- Sun Sep 19 11:03:57 CEST 2010 - vuntz@opensuse.org - Update to version 8.10: + Major additions: - support for (*MARK) and friends - PCRE_UCP option, which changes the behaviour of \b, \d, \s, and \w (and their opposites) so that they make use of Unicode properties + Other additions: - support for \N, which always matches any character other than newline - added --line-buffered to pcregrep + Several small new features and bugfixes - Changes from version 8.02: + Update Unicode data tables to Unicode 5.2.0 + Update the licensing terms in the pcregexp.pas file + Several bug fixes - Changes from version 8.01: + Several bug fixes and build system improvements - Changes from version 8.00: + Enhancements: - remove restrictions on patterns used for partial matching - give extra information for partial matches - improve the partial matching process - add option to make a partial match override a full match - enhance "study" process by finding a lower bound matching length - groups with duplicate numbers may now have duplicated names without the use of PCRE_DUPNAMES, but they may not have different names - add REG_UNGREEDY to the pcreposix interface, which maps to PCRE_UNGREEDY. + Several bug fixes - Drop pcre-7.9.patch: fixed upstream. - Rearrange spec file to have all the %files sections together, as well as all the scriptlets together. - Kill the main package that only included doc files like AUTHORS, NEWS, and license, and put those files in libpcre0: this really makes more sense. Therefore, make libpcre0 Provides/Obsoletes libpcre0. - We can also remove the other dependencies on the main package, since everything already depends on libpcre0. - Remove AutoReqProv: it's default now. - Remove references to perl 5.005 in descriptons: it's not mentioned anywhere anymore upstream. ------------------------------------------------------------------- Mon Jun 28 06:38:35 UTC 2010 - jengelh@medozas.de - use %_smp_mflags ------------------------------------------------------------------- Sat Apr 24 10:38:30 UTC 2010 - coolo@novell.com - buildrequire pkg-config to fix provides ------------------------------------------------------------------- Thu Feb 25 16:49:20 UTC 2010 - prusnak@suse.cz - build noarch docs only for >= 11.2 ------------------------------------------------------------------- Wed Feb 10 16:16:56 CET 2010 - ms@suse.de - fixed license statement according to the conversation and permissions granted in (bnc #578724) ------------------------------------------------------------------- Sat Dec 12 18:38:47 CET 2009 - jengelh@medozas.de - add baselibs.conf as a source - package documentation as noarch ------------------------------------------------------------------- Wed Oct 7 12:51:05 UTC 2009 - coolo@novell.com - add obsolete/provides for pcre-32bit (bnc#539543) ------------------------------------------------------------------- Wed Jun 10 13:03:11 CEST 2009 - coolo@novell.com - split package into tools, docs and libraries ------------------------------------------------------------------- Fri Jun 5 23:13:22 CEST 2009 - crrodriguez@suse.de - disable static libraries, shouldn't be used now ------------------------------------------------------------------- Sat May 30 22:02:07 CEST 2009 - dmueller@suse.de - fix symlinks to libpcre and libpcreposix to fix the build ------------------------------------------------------------------- Wed May 27 18:03:13 CEST 2009 - ms@suse.de - moved libpcre and libpcreposix to %{_lib} (bnc #507449) ------------------------------------------------------------------- Tue May 5 14:24:17 CEST 2009 - ms@suse.de - Release 7.9 11-Apr-09 (bnc #500734) Mostly bugfixes and tidies with just a couple of minor functional additions. ------------------------------------------------------------------- Wed Jan 7 12:34:56 CET 2009 - olh@suse.de - obsolete old -XXbit packages (bnc#437293) ------------------------------------------------------------------- Fri Sep 12 01:51:31 CEST 2008 - crrodriguez@suse.de - update to PCRE 7.8 * More bug fixes, plus a performance improvement in Unicode character property lookup. see complete changelog at http://www.pcre.org/changelog.txt ------------------------------------------------------------------- Thu Apr 10 12:54:45 CEST 2008 - ro@suse.de - added baselibs.conf file to build xxbit packages for multilib support ------------------------------------------------------------------- Fri Feb 1 19:43:16 CET 2008 - crrodriguez@suse.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 09:08:22 CET 2008 - crrodriguez@suse.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 <windows.h> 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 08:15:28 CET 2007 - crrodriguez@suse.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 12:46:16 CEST 2007 - ms@suse.de - added fix to run ldconfig for libpcre*, Thanks to Cristian Rodriguez <crrodriguez@novell.com> who provided the patch (#298291) ------------------------------------------------------------------- Mon Jul 23 15:22:40 CEST 2007 - ms@suse.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<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. ------------------------------------------------------------------- Tue May 1 11:02:54 CEST 2007 - ms@suse.de - added --enable-unicode-properties configure option to support UTF-8 character strings in \P, \p, and \X (#269749) ------------------------------------------------------------------- Mon Apr 30 10:12:10 CEST 2007 - trenn@suse.de - corrected assert compile error ------------------------------------------------------------------- Wed Apr 25 13:39:55 CEST 2007 - ms@suse.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 \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. ------------------------------------------------------------------- Fri Feb 9 10:07:29 CET 2007 - ms@suse.de - fixed wrong usage of assert() call ------------------------------------------------------------------- Tue Jan 9 11:28:53 CET 2007 - ms@suse.de - fixed build for all architectures ------------------------------------------------------------------- Mon Jan 8 16:07:02 CET 2007 - ms@suse.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 17:50:04 CEST 2006 - meissner@suse.de - CXXFLAGS needs RPM_OPT_FLAGS too. ------------------------------------------------------------------- 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". ------------------------------------------------------------------- Wed Jan 25 21:30:47 CET 2006 - mls@suse.de - converted neededforbuild to BuildRequires ------------------------------------------------------------------- Thu Jan 12 13:53:17 CET 2006 - mmj@suse.de - build with -fstack-protector ------------------------------------------------------------------- Thu Dec 1 01:39:04 CET 2005 - ro@suse.de - hack libtool core in configure script since configure.in is too broken for a autoreconf ... ------------------------------------------------------------------- Mon Sep 19 17:53:52 CEST 2005 - mmj@suse.de - update to the latest version v6.4 ------------------------------------------------------------------- Tue Aug 2 11:19:20 CEST 2005 - mmj@suse.de - update to the latest version v6.2 ------------------------------------------------------------------- Thu Jun 23 13:18:50 CEST 2005 - mmj@suse.de - update to latest version v6.1 ------------------------------------------------------------------- Mon Jun 13 08:51:51 CEST 2005 - mmj@suse.de - add gcc-c++ to #nfb as well ------------------------------------------------------------------- Wed Jun 8 23:41:35 CEST 2005 - mmj@suse.de - update to latest version v6.0 ------------------------------------------------------------------- Mon May 23 11:17:20 CEST 2005 - mmj@suse.de - use --enable-utf8 - use $RPM_OPT_FLAGS ------------------------------------------------------------------- Thu Mar 31 17:39:53 CEST 2005 - uli@suse.de - ignore test suite errors on ARM ------------------------------------------------------------------- Mon Nov 22 17:12:31 CET 2004 - choeger@suse.de - update to latest version v5.0 ------------------------------------------------------------------- Mon Jun 7 11:40:27 CEST 2004 - choeger@suse.de - update to latest version v4.5 ------------------------------------------------------------------- Mon Jan 5 15:39:13 CET 2004 - schwab@suse.de - Move pcre-config to pcre-devel. ------------------------------------------------------------------- Fri Oct 31 17:05:26 CET 2003 - choeger@suse.de - Don't build as root ------------------------------------------------------------------- Thu Aug 21 15:22:38 CEST 2003 - choeger@suse.de - update to v4.4 ------------------------------------------------------------------- Fri Aug 1 12:07:27 CEST 2003 - choeger@suse.de - disabled Test2, because it is not 64bit arch clean (contacted author, he knows about that problem) ------------------------------------------------------------------- Wed Jul 30 14:56:52 CEST 2003 - choeger@suse.de - update to most recent version v4.3 - splitted into -devel subpackage ------------------------------------------------------------------- Fri Dec 6 04:42:15 CET 2002 - coolo@suse.de - removed undefined symbols in libpcreposix ------------------------------------------------------------------- Tue Sep 17 17:34:28 CEST 2002 - ro@suse.de - removed bogus self-provides ------------------------------------------------------------------- Fri Apr 5 10:57:15 CEST 2002 - coolo@suse.de - fixing autoheader usage - forward ported %libdir changes from sles7-s390x ------------------------------------------------------------------- Tue Jan 22 19:07:26 CET 2002 - choeger@suse.de - update to version 3.9 - added BuildRoot ------------------------------------------------------------------- Tue Aug 21 01:11:46 MEST 2001 - mge@suse.de - pcre 3.5 ------------------------------------------------------------------- Wed Apr 11 22:26:54 CEST 2001 - froh@suse.de - suse_update_config ------------------------------------------------------------------- Mon Dec 4 12:08:52 MET 2000 - mge@suse.de - pcre 3.4 ------------------------------------------------------------------- Tue Jun 27 19:41:41 MEST 2000 - mge@suse.de - pcre 3.2 ------------------------------------------------------------------- Thu Mar 2 12:22:48 CET 2000 - mge@suse.de - fixed manpath ------------------------------------------------------------------- Sun Feb 13 16:54:53 MET 2000 - mge@suse.de - update to 3.1 - group tag ------------------------------------------------------------------- Mon Oct 25 23:38:47 MEST 1999 - mge@suse.de - initial SuSE-RPM: changed Makefile to install into /usr
