Subject: [PATCH v2 05/29] grep: add a test asserting that --perl-regexp dies when !PCRE
Date: Sat, 13 May 2017 23:14:45 +0000 [thread overview]
Message-ID: <20170513231509.7834-6-avarab@gmail.com> (raw)
In-Reply-To: <20170513231509.7834-1-avarab@gmail.com>
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.
