Subject: [PATCHv2 07/21] completion: ensure that the repository path given on the command line exists
Date: Fri,  3 Feb 2017 03:48:15 +0100	[thread overview]
Message-ID: <20170203024829.8071-8-szeder.dev@gmail.com> (raw)
In-Reply-To: <20170203024829.8071-1-szeder.dev@gmail.com>

The __gitdir() helper function prints the path to the git repository
to its stdout or stays silent and returns with error when it can't
find a repository or when the repository given via $GIT_DIR doesn't
exist.

This is not the case, however, when the path in $__git_dir, i.e. the
path to the repository specified on the command line via 'git
--git-dir=<path>', doesn't exist: __gitdir() still outputs it as if it
were a real existing repository, making some completion functions
believe that they operate on an existing repository.

Check that the path in $__git_dir exists and return with error without
printing anything to stdout if it doesn't.
