Name : pcre2
Product : Fedora 31
Version : 10.34
Release : 8.fc31
URL : https://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. This package provides support for strings in 8-bit and UTF-8
encodings. Install pcre2-utf16 or pcre2-utf32 packages for the other ones.
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.

Update Information:
This release fixes computing an offest for the start of the UTF-16 error when a
high surrogate is not followed by a valid low surrogate, compiling a lookbehind
when preceded by a DEFINE group, and makes manual pages about the pattern syntax
always available.

ChangeLog:
* Mon Mar 16 2020 Petr Pisar <ppisar(a)redhat.com> - 10.34-8
- Fix computing an offest for the start of the UTF-16 error when a high
surrogate is not followed by a valid low surrogate (upstream bug #2527)

(upstream bug #2531)
- Make manual pages about pattern syntax available when the library is
installed (bug #1808612)
--------------------------------------------------------------------------------
References:
[ 1 ] Bug #1808612 - The pcre2 manual pages are in the devel packages but they describe
the syntax and therefore are necessary all the time
