Subject: [PATCHv2 19/21] completion: don't guard git executions with __gitdir()
Date: Fri, 3 Feb 2017 03:48:27 +0100 [thread overview]
Message-ID: <20170203024829.8071-20-szeder.dev@gmail.com> (raw)
In-Reply-To: <20170203024829.8071-1-szeder.dev@gmail.com>
Three completion functions, namely __git_index_files(), __git_heads()
and __git_tags(), first run __gitdir() and check that the path it
outputs exists, i.e. that there is a git repository, and run a git
command only if there is one.
After the previous changes in this series there are no further uses of
__gitdir()'s output in these functions besides those checks. And
those checks are unnecessary, because we can just execute those git
commands outside of a repository and let them error out. We don't
perform such a check in other places either.
Remove this check and the __gitdir() call from these functions,
sparing the fork()+exec() overhead of the command substitution and the
potential 'git rev-parse' execution.
