| Summary: A library for Perl-compatible regular expressions | |
The PCRE2 library is a set of functions that implement regular expression pattern matching using the same syntax and semantics as Perl 5. PCRE2 is a re-working of the original PCRE library to provide an entirely new API. libpcre2-16 supports 16-bit and UTF-16 strings.
BSD-3-Clause
* Sun Feb 18 2018 avindra@opensuse.org
- Update to new upstream release 10.31
* New pcre2_config() options: PCRE2_CONFIG_NEVER_BACKSLASH_C and
PCRE2_CONFIG_COMPILED_WIDTHS.
* New pcre2_pattern_info() option PCRE2_INFO_EXTRAOPTIONS to
retrieve the extra compile time options.
* Public names for all pcre2_compile() error numbers.
* Added PCRE2_CALLOUT_STARTMATCH and PCRE2_CALLOUT_BACKTRACK
bits to a new field callout_flags in callout blocks.
- use https for main site
- cleanup with spec-cleaner
* Mon Sep 11 2017 jengelh@inai.de
- Update to new upstream release 10.30
* The main interpreter, pcre2_match(), has been refactored into
a new version that does not use recursive function calls for
remembering backtracking positions. The new implementation
allows backtracking into recursive group calls in patterns,
making it more compatible with Perl. For patterns that have a
lot of backtracking, the heap is now used, and there is
explicit limit on the amount, settable by
pcre2_set_heap_limit(). The "recursion limit" is retained,
but is renamed as "depth limit".
* The new option PCRE2_ENDANCHORED insists that a pattern match
must end at the end of the subject.
* The new option PCRE2_EXTENDED_MORE implements Perl's /xx
feature, and pcre2test is upgraded to support it. Setting
within the pattern by (?xx) is Also supported.
* (?n) can be used to set PCRE2_NO_AUTO_CAPTURE, because Perl
now has this.
* Additional pattern compile options in the compile context are
now available: PCRE2_EXTRA_ALLOW_SURROGATE_ESCAPES and
PCRE2_EXTRA_BAD_ESCAPE_IS LITERAL.
* The newline type PCRE2_NEWLINE_NUL is now available.
* The match limit value now also applies to pcre2_dfa_match()
as there are patterns that can use up a lot of resources
without necessarily recursing very deeply.
* Various minor security fixes found by fuzzers:
+ bsc#1037165: crash for forward reference in lookbehind with
PCRE2_ANCHORED
+ CVE-2017-8786: heap-based buffer overflow write in pcre2test
(bsc#1036942)
+ CVE-2017-7186: DoS by triggering an invalid Unicode property
lookup (bsc#1030066)

* Sat Aug 05 2017 astieger@suse.com
- fix SLE 11 build
* Tue May 02 2017 astieger@suse.com
- pcre2grep can now read .gz and .bz2 files directly
- pcre2test is now built to support line editing
* Thu Feb 16 2017 astieger@suse.com
- pcre2 10.23:
* major re-factoring of the pcre2_compile.c file
* Back references are now permitted in lookbehind assertions when
there are no duplicated group numbers (that is, (?| has not
been used), and, if the reference is by name, there is only one
group of that name. The referenced group must, of course be of
fixed length.
* \g{+<number>} (e.g. \g{+2} ) is now supported. It is a "forward
back reference" and can be useful in repetitions
(compare \g{-<number>} ). Perl does not recognize this syntax.
* pcre2grep now automatically expands its buffer up to a maximum
set by --max-buffer-size.
* The -t option (grand total) has been added to pcre2grep.
* A new function called pcre2_code_copy_with_tables() exists to
copy a compiled pattern along with a private copy of the
character tables that is uses.
* Tue Feb 07 2017 dimstar@opensuse.org
- Explicitly package %{_docdir}/%{name} to fix build with RPM 4.13.
* Mon Aug 01 2016 astieger@suse.com
- pcre2 10.22:
* The POSIX wrapper function regcomp() did not used to
support back references and subroutine calls if called with the
REG_NOSUB option. It now does.
* A new function, pcre2_code_copy(), is added, to make a copy of a
compiled pattern.
* Support for string callouts is added to pcre2grep.
* Added the PCRE2_NO_JIT option to pcre2_match().
* The pcre2_get_error_message() function now returns with a
negative error code if the error number it is given is unknown.
* Several updates have been made to pcre2test and test scripts
* Fix CVE-2016-3191: workspace overflow for (*ACCEPT) with deeply
nested parentheses (boo#971741)
* Sun Jan 17 2016 jengelh@inai.de
- Update to new upstream release 10.21
* Improve JIT matching speed of patterns starting with + or *.
* Use memchr() to find the first character in an unanchored match
in 8-bit mode in the interpreter. This gives a significant speed
improvement.
* 10.20 broke the handling of [[:>:]] and [[:<:]] in that
processing them could involve a buffer overflow if the
following character was an opening parenthesis.
* 10.20 also introduced a bug in processing this pattern:
/((?x)(*:0))#(?'/, which was fixed.
* A callout with a string argument containing an opening square
bracket, for example /(?C$[$)(?<]/, was incorrectly processed and
could provoke a buffer overflow.
* A possessively repeated conditional group that could match an empty
string, for example, /(?(R))*+/, was incorrectly compiled.
* The Unicode tables have been updated to Unicode 8.0.0.
* An empty comment (?#) in a pattern was incorrectly processed and
could provoke a buffer overflow.
* Fix infinite recursion in the JIT compiler when certain patterns
/such as (?:|a|){100}x/ are analysed.
* Some patterns with character classes involving [: and \\ were
incorrectly compiled and could cause reading from uninitialized
memory or an incorrect error diagnosis. Examples are:
/[[:\\](?<[::]/ and /[[:\\](?'abc')[a:].
* A missing closing parenthesis for a callout with a string argument
was not being diagnosed, possibly leading to a buffer overflow.
* If (?R was followed by - or + incorrect behaviour happened instead
of a diagnostic.
* Fixed an issue when \p{Any} inside an xclass did not read the current
character.
* About 80 more fixes, which you can read about in the ChangeLog
shipped with the libpcre2-8-0 package.
* Tue Jul 14 2015 astieger@suse.com
- PCRE2 10.20:
* Callouts with string arguments and the
pcre2_callout_enumerate() function have been implemented.
* The PCRE2_NEVER_BACKSLASH_C option, which locks out the use of
\C, is added.
* The PCRE2_ALT_CIRCUMFLEX option lets ^ match after a newline at
the end of a subject in multiline mode.
* The way named subpatterns are handled has been refactored. The
previous approach had several bugs.
* The handling of \c in EBCDIC environments has been changed to
conform to the perlebcdic document. (Incompatible change)
* Bugs have been mended, many of them discovered by fuzzers.
