From 9001c1920c9b812efc671bdc0c313d0a3418d8ee Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=C3=86var=20Arnfj=C3=B6r=C3=B0=20Bjarmason?= Date: Sat, 20 May 2017 21:42:09 +0000 Subject: [PATCH] grep: add a test asserting that --perl-regexp dies when !PCRE MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add a test asserting that when --perl-regexp (and -P for grep) is given to git-grep & git-log that we die with an error. In developing the PCRE v2 series I introduced a regression where -P would (through control-flow fall-through) become synonymous with basic POSIX matching. I.e. 'git grep -P '[\d]' would match "d" instead of digits. The entire test suite would still pass with this serious regression, since everything that tested for --perl-regexp would be guarded by the PCRE prerequisite, fix that blind-spot by adding tests under !PCRE asserting that git must die when given --perl-regexp or -P.
