Subject: [PATCH v2 01/10] merge: make xopts a strvec
Date: Thu, 31 Aug 2023 17:17:11 -0400 [thread overview]
Message-ID: <20230831211711.GA949469@coredump.intra.peff.net> (raw)
In-Reply-To: <20230831211637.GA949188@coredump.intra.peff.net>
The "xopts" variable uses a custom array with ALLOC_GROW(). Using a
strvec simplifies things a bit. We need fewer variables, and we can also
ditch our custom parseopt callback in favor of OPT_STRVEC().
As a bonus, this means that "--no-strategy-option", which was previously
a silent noop, now does something useful: like other list-like options,
it will clear the list of -X options seen so far. This matches the
behavior of revert/cherry-pick, which made the same change in fb60b9f37f
(sequencer: use struct strvec to store merge strategy options,
2023-04-10).
