Subject: [PATCH v2 3/3] sequencer: fix a memory leak in do_reset()
Date: Thu, 7 Oct 2021 11:46:11 +0200 [thread overview]
Message-ID: <patch-v2-3.3-66ae63db8fd-20211007T094019Z-avarab@gmail.com> (raw)
In-Reply-To: <cover-v2-0.3-00000000000-20211007T094019Z-avarab@gmail.com>
Fix a memory leak introduced in 9055e401dd6 (sequencer: introduce new
commands to reset the revision, 2018-04-25), which called
setup_unpack_trees_porcelain() without a corresponding call to
clear_unpack_trees_porcelain().
This inches us closer to passing various tests in
"t34*.sh" (e.g. "t3434-rebase-i18n.sh"), but because they have so many
other memory leaks in revisions.c this doesn't make any test file or
even a single test pass.
