Subject: [PATCH 1/4] rebase: stop reading and writing unnecessary strategy state
Date: Wed, 15 Mar 2023 15:14:56 +0000 [thread overview]
Message-ID: <029d0bf2b6249ddc3e79fe1bf3df3e05d22348ad.1678893298.git.phillip.wood@dunelm.org.uk> (raw)
In-Reply-To: <cover.1678893298.git.phillip.wood@dunelm.org.uk>
From: Phillip Wood <phillip.wood@dunelm.org.uk>
The state files for "--strategy" and "--strategy-option" are written and
read twice, once by builtin/rebase.c and then by sequencer.c. This is an
artifact of the scripted rebase and the need to support "rebase
--preserve-merges". Now that "--preserve-merges" no-longer exists we
only need to read and write these files in sequencer.c. This enables us
to remove a call to free() in read_strategy_opts() that was added by
f1f4ebf432 (sequencer.c: fix "opts->strategy" leak in
read_strategy_opts(), 2022-11-08) as this commit fixes the root cause of
that leak.
There is further scope for removing duplication in the reading and
writing of state files between builtin/rebase.c and sequencer.c but that
is left for a follow up series.
