-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 This is to announce grep-2.22, a stable release. Special thanks to Norihiro Tanaka and Paul Eggert for making so many fine changes.
There have been 86 commits by 6 people in the 49 weeks since 2.21. See the NEWS below for a brief summary. Thanks to everyone who has contributed! The following people contributed changes to this release: Jim Meyering (34) Norihiro Tanaka (17) Paul Eggert (32) Santiago Ruano Rincón (1) Yuliy Pisetsky (1) Zev Weiss (1) Jim [on behalf of the grep maintainers] ================================================================== Here is the GNU grep home page: http://gnu.org/s/grep/ For a summary of changes and contributors, see: http://git.sv.gnu.org/gitweb/?p=grep.git;a=shortlog;h=v2.22 or run this command from a git-cloned grep directory: git shortlog v2.21..v2.22 To summarize the 344 gnulib-related changes, run these commands from a git-cloned grep directory: git checkout v2.22 git submodule summary v2.21 Here are the compressed sources and a GPG detached signature[*]: http://ftp.gnu.org/gnu/grep/grep-2.22.tar.xz http://ftp.gnu.org/gnu/grep/grep-2.22.tar.xz.sig Use a mirror for higher download bandwidth: http://ftpmirror.gnu.org/grep/grep-2.22.tar.xz http://ftpmirror.gnu.org/grep/grep-2.22.tar.xz.sig [*] Use a .sig file to verify that the corresponding file (without the .sig suffix) is intact. First, be sure to download both the .sig file and the corresponding tarball. Then, run a command like this: gpg --verify grep-2.22.tar.xz.sig If that command fails because you don't have the required public key, then run this command to import it: gpg --keyserver keys.gnupg.net --recv-keys 7FD9FCCB000BEEEE and rerun the 'gpg --verify' command. This release was bootstrapped with the following tools: Autoconf 2.69.147-5ad35 Automake 1.99a Gnulib v0.1-606-g956fa54 ================================================================== NEWS * Noteworthy changes in release 2.22 (2015-11-01) [stable] ** Improvements Performance has improved for patterns containing very long strings, reducing preprocessing time for an N-byte regexp from O(N^2) to only slightly superlinear for most patterns. Before, a command like the following would take over a minute, but now, it takes less than a second: : | grep -f <(seq -s '' 99999) When building grep, 'configure' now uses PCRE's pkg-config module for configuration information, rather than attempting to guess it by hand. ** Bug fixes A DFA matcher bug made this command mistakenly print its input line: echo axb | grep -E '^x|x$' Likewise for this equivalent command: echo axb | grep -e '^x' -e 'x$' [bug introduced in grep-2.19 ] grep no longer reads from uninitialized memory or from beyond the end of the heap-allocated input buffer. This fix addressed CVE-2015-1345. [bug introduced in grep-2.19 ] With -z, '.' and '[^x]' in a pattern now consistently match newline. Previously, they sometimes matched newline, and sometimes did not. [bug introduced in grep-2.4] When the JIT stack is exhausted, grep -P now grows the stack rather than reporting an internal PCRE error. 'grep -D skip PATTERN FILE' no longer hangs if FILE is a fifo. [bug introduced in grep-2.12] --exclude and related options are now matched against entire command-line arguments, not against command-line components. [bug introduced in grep-2.6] Fix performance degradation of grep -Fw in unibyte locales.
