#49558: grep @2.21_0: update to 2.22 ---------------------------------+-------------------------------- Reporter: mschamschula@… | Owner: macports-tickets@… Type: update | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.3.4 Keywords: haspatch maintainer | Port: grep ---------------------------------+-------------------------------- GNU grep has been update to version 2.22: ** 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.
