Subject: [PATCH] t1300: fix unset of GIT_CONFIG_NOSYSTEM leaking into subsequent tests
Date: Fri, 23 Apr 2021 07:47:15 +0200	[thread overview]
Message-ID: <5b69d9d34e4bdf1c7eb3b172ad8ef0f78542c789.1619156659.git.ps@pks.im> (raw)
In-Reply-To: <20210421204637.GA2947267@szeder.dev>

[-- Attachment #1: Type: text/plain, Size: 1921 bytes --]

In order to test whether the new GIT_CONFIG_SYSTEM environment variable
behaves as expected, we unset GIT_CONFIG_NOSYSTEM in one of our tests in
t1300. But because tests are not executed in a subshell, this unset
leaks into all subsequent tests and may thus cause them to fail in some
environments. These failures are easily reproducable with `make
prefix=/root test`.

Fix the issue by not using `sane_unset GIT_CONFIG_NOSYSTEM`, but instead
just manually add it to the environment of the two command invocations
which need it.
