Subject: [PATCH 7/9] t0060: test ntfs/hfs-obscured dotfiles
Date: Sat, 1 May 2021 11:42:54 -0400	[thread overview]
Message-ID: <YI12/oqmfIoSuxN2@coredump.intra.peff.net> (raw)
In-Reply-To: <YI12hK4X/gfl3u29@coredump.intra.peff.net>

We have tests that cover various filesystem-specific spellings of
".gitmodules", because we need to reliably identify that path for some
security checks. These are from dc2d9ba318 (is_{hfs,ntfs}_dotgitmodules:
add tests, 2018-05-12), with the actual code coming from e7cb0b4455
(is_ntfs_dotgit: match other .git files, 2018-05-11) and 0fc333ba20
(is_hfs_dotgit: match other .git files, 2018-05-02).

Those latter two commits also added similar matching functions for
.gitattributes and .gitignore. These ended up not being used in the
final series, and are currently dead code. But in preparation for them
being used in some fsck checks, let's make sure they actually work by
throwing a few basic tests at them. Likewise, let's cover .mailmap
(which does need matching code added).

I didn't bother with the whole battery of tests that we cover for
.gitmodules. These functions are all based on the same generic matcher,
so it's sufficient to test most of the corner cases just once.

Note that the ntfs magic prefix names in the tests come from the
algorithm described in e7cb0b4455 (and are different for each file).
