Subject: [PATCH v3 15/15] t1507: inline full_name()
Date: Fri, 20 Dec 2019 10:16:02 -0800	[thread overview]
Message-ID: <4fe445279b715b3a49e7635adc1af152de183bff.1576865664.git.liu.denton@gmail.com> (raw)
In-Reply-To: <cover.1576865663.git.liu.denton@gmail.com>

Before, we were running `test_must_fail full_name`. However,
`test_must_fail` should only be used on git commands. Inline full_name()
so that we can use test_must_fail on the git command directly.

When full_name() was introduced in 28fb84382b (Introduce
<branch>@{upstream} notation, 2009-09-10), the `git -C` option wasn't
available yet (since it was introduced in 44e1e4d67d (git: run in a
directory given with -C option, 2013-09-09)). As a result, the helper
function removed the need to manually cd each time. However, since
`git -C` is available now, we can just use that instead and inline
full_name().

An alternate approach was taken where we taught full_name() to accept an
optional `!` arg to trigger test_must_fail behavior. However, this added
more unnecessary complexity than inlining so we inline instead.
