Subject: [PATCH v2 5/9] midx: enable core.multiPackIndex by default
Date: Tue, 18 Aug 2020 14:25:26 +0000 [thread overview]
Message-ID: <0ee2434bdbabc6f3ed6e80402aa3a19bf9626fc6.1597760730.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.696.v2.git.1597760730.gitgitgadget@gmail.com>
From: Derrick Stolee <dstolee@microsoft.com>
The core.multiPackIndex setting has been around since c4d25228ebb
(config: create core.multiPackIndex setting, 2018-07-12), but has been
disabled by default. If a user wishes to use the multi-pack-index
feature, then they must enable this config and run 'git multi-pack-index
write'.
The multi-pack-index feature is relatively stable now, so make the
config option true by default. For users that do not use a
multi-pack-index, the only extra cost will be a file lookup to see if a
multi-pack-index file exists (once per process, per object directory).
Also, this config option will be referenced by an upcoming
"incremental-repack" task in the maintenance builtin, so move the config
option into the repository settings struct. Note that if
GIT_TEST_MULTI_PACK_INDEX=1, then we want to ignore the config option
and treat core.multiPackIndex as enabled.
