Subject: [PATCH] CodingGuidelines: explicitly allow "local" for test scripts
Date: Mon, 03 May 2021 13:10:58 +0900	[thread overview]
Message-ID: <xmqqfsz4a23x.fsf@gitster.g> (raw)

01d3a526 (t0000: check whether the shell supports the "local"
keyword, 2017-10-26) raised a test balloon to see if those who build
and test Git use a platform without a shell that lacks support for
the "local" keyword.  After two years, 7f0b5908 (t0000: reword
comments for "local" test, 2019-08-08) documented that "local"
keyword, even though is outside POSIX, is allowed in our test
scripts.

Let's write it in the CodingGuidelines, too.  It might be tempting
to allow it in scripted Porcelains (we have avoided getting them
contaminiated by "local" so far), but they are on their way out and
getting rewritten in C.
