From beb6ee71639ffe96f676ba4268cb85e4a933ab7e Mon Sep 17 00:00:00 2001 From: =?utf8?q?SZEDER=20G=C3=A1bor?= Date: Fri, 3 Feb 2017 03:48:28 +0100 Subject: [PATCH] completion: extract repository discovery from __gitdir() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit To prepare for caching the path to the repository in the following commit, extract the repository discovering part of __gitdir() into the __git_find_repo_path() helper function, which stores the found path in the $__git_repo_path variable instead of printing it. Make __gitdir() a wrapper around this new function. Declare $__git_repo_path local in the toplevel completion functions __git_main() and __gitk_main() to ensure that it never leaks into the environment and influences subsequent completions (though this isn't necessary right now, as __gitdir() is still only executed in subshells, but will matter for the following commit). Adjust tests checking __gitdir() or any other completion function calling __gitdir() to perform those checks in a subshell to prevent $__git_repo_path from leaking into the test environment. Otherwise leave the tests unchanged to demonstrate that this change doesn't alter __gitdir()'s behavior.
