Subject: [PATCH v4 3/4] t7508: add tests capturing racy timestamp handling
Date: Fri, 07 Jan 2022 11:17:30 +0000	[thread overview]
Message-ID: <82d0b6ab8d2dc3198216aac9551927dfd6d91cc0.1641554252.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.1105.v4.git.1641554252.gitgitgadget@gmail.com>

From: Marc Strapetz <marc.strapetz@syntevo.com>

"git status" fixes racy timestamps regardless of the worktree being
dirty or not. The new test cases capture this behavior.
