-------------------------------------------------------------------------------- Fedora EPEL Update Notification FEDORA-EPEL-2017-fdcd61a2be 2017-05-04 13:28:00.660821 --------------------------------------------------------------------------------

Name : pcre2 Product : Fedora EPEL 7 Version : 10.21 Release : 18.el7 URL : http://www.pcre.org/ Summary : Perl-compatible regular expression library Description : PCRE2 is a re-working of the original PCRE (Perl-compatible regular expression) library to provide an entirely new API.

PCRE2 is written in C, and it has its own API. There are three sets of functions, one for the 8-bit library, which processes strings of bytes, one for the 16-bit library, which processes strings of 16-bit values, and one for the 32-bit library, which processes strings of 32-bit values. There are no C++ wrappers.

The distribution does contain a set of C wrapper functions for the 8-bit library that are based on the POSIX regular expression API (see the pcre2posix man page). These can be found in a library called libpcre2posix. Note that this just provides a POSIX calling interface to PCRE2; the regular expressions themselves still follow Perl syntax and semantics. The POSIX API is restricted, and does not give full access to all of PCRE2's facilities.

This release fixes a crash when finding a Unicode property for a character with a code point greater than 0x10ffff in UTF-32 library while UTF mode is disabled and JIT mode is enabled. It also fixes an incortect cast in UTF validation routine. ---- This release fixes DFA magch for a possessively repeated character class and a memory allocator from the pattern if no context is supplied to pcre2_match(). ---- This release closes serialization file in pcre2test after any error and it fixes a potential NULL dereference in pcre2_callout_enumerate() if called with a NULL pattern pointer when Unicode support is available. ---- This release fixes a pcre2test bug for global match with zero terminated subject. -------------------------------------------------------------------------------- References:
