From a84fd3bcc6253f847af3366ebb9de9b8f441a624 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Mon, 3 May 2021 14:23:24 +0900 Subject: [PATCH] CodingGuidelines: explicitly allow "local" for test scripts 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 with 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.
