Subject: [WIP RFC PATCH 4/7] clone: test for our behavior on odd objects/* content
Date: Tue, 26 Feb 2019 01:26:22 +0100	[thread overview]
Message-ID: <20190226002625.13022-5-avarab@gmail.com> (raw)
In-Reply-To: <CACsJy8Bw-mXLyT7VaKBjYKLe6uSAQqyLG=_AzjDXykYzSQLkcg@mail.gmail.com>

We've implicitly supported .git/objects/* content of symlinks since
approximately forever, and when we do a copy of the repo we transfer
those over, but aren't very consistent about other random stuff we
find depending on if it's a "hidden" file or not.

Let's add a test for that, which shouldn't read as an endorsement of
what we're doing now, just asserts current behavior.
