Subject: [PATCH v6 0/2] hook API: connect hooks to the TTY again, fixes a v2.36.0 regression
Date: Tue,  7 Jun 2022 10:48:18 +0200	[thread overview]
Message-ID: <cover-v6-0.2-00000000000-20220606T170356Z-avarab@gmail.com> (raw)
In-Reply-To: <cover-v5-0.2-00000000000-20220602T131858Z-avarab@gmail.com>

This series fixes a v2.36.0 regression[1]. See [2] for the v5. The
reasons for why a regression needs this relatively large change to
move forward is discussed in past rounds, e.g. around [3]. CI at
https://github.com/avar/git/actions/runs/2448496389

Changes since v5:

 * Make the hook run test more meaningful, we now test with "-t" in
   the hook, instead of redirecting one of STDOUT or STDERR.

 * Add a test for both "git hook run" and "git commit", to showh that
   the "git hook run" command and one "real" user of it agree.
