Subject: [PATCH v3 10/10] t5325: check both on-disk and in-memory reverse index
Date: Mon, 25 Jan 2021 18:37:51 -0500	[thread overview]
Message-ID: <38c8afabf25a7f5e144850938cf00b53e9cf25fd.1611617820.git.me@ttaylorr.com> (raw)
In-Reply-To: <cover.1611617819.git.me@ttaylorr.com>

Right now, the test suite can be run with 'GIT_TEST_WRITE_REV_INDEX=1'
in the environment, which causes all operations which write a pack to
also write a .rev file.

To prepare for when that eventually becomes the default, we should
continue to test the in-memory reverse index, too, in order to avoid
losing existing coverage. Unfortuantely, explicit existing coverage is
rather sparse, so only a basic test is added.

The new test is parameterized over whether or not the .rev file should
be written, and is run in both modes by t5325 (without having to touch
GIT_TEST_WRITE_REV_INDEX).
