Now that multi-pack reuse is supported, enable it via the feature.experimental configuration in addition to the classic `pack.allowPackReuse`. This will allow more users to experiment with the new behavior who might not otherwise be aware of the existing `pack.allowPackReuse` configuration option. The enum with values NO_PACK_REUSE, SINGLE_PACK_REUSE, and MULTI_PACK_REUSE is defined statically in builtin/pack-objects.c's compilation unit. We could hoist that enum into a scope visible from the repository_settings struct, and then use that enum value in pack-objects. Instead, define a single int that indicates what pack-objects's default value should be to avoid additional unnecessary code movement. Though `feature.experimental` implies `pack.allowPackReuse=multi`, this can still be overridden by explicitly setting the latter configuration to either "single" or "false". Tests covering all of these cases are showin t5332. Signed-off-by: Taylor Blau <me@ttaylorr.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

feature.*::
|
|
The config settings that start with `feature.` modify the defaults of
|
|
a group of other config settings. These groups are created by the Git
|
|
developer community as recommended defaults and are subject to change.
|
|
In particular, new config options may be added with different defaults.
|
|
|
|
feature.experimental::
|
|
Enable config options that are new to Git, and are being considered for
|
|
future defaults. Config settings included here may be added or removed
|
|
with each release, including minor version updates. These settings may
|
|
have unintended interactions since they are so new. Please enable this
|
|
setting if you are interested in providing feedback on experimental
|
|
features. The new default values are:
|
|
+
|
|
* `fetch.negotiationAlgorithm=skipping` may improve fetch negotiation times by
|
|
skipping more commits at a time, reducing the number of round trips.
|
|
+
|
|
* `pack.useBitmapBoundaryTraversal=true` may improve bitmap traversal times by
|
|
walking fewer objects.
|
|
+
|
|
* `pack.allowPackReuse=multi` may improve the time it takes to create a pack by
|
|
reusing objects from multiple packs instead of just one.
|
|
|
|
feature.manyFiles::
|
|
Enable config options that optimize for repos with many files in the
|
|
working directory. With many files, commands such as `git status` and
|
|
`git checkout` may be slow and these new defaults improve performance:
|
|
+
|
|
* `index.skipHash=true` speeds up index writes by not computing a trailing
|
|
checksum. Note that this will cause Git versions earlier than 2.13.0 to
|
|
refuse to parse the index and Git versions earlier than 2.40.0 will report
|
|
a corrupted index during `git fsck`.
|
|
+
|
|
* `index.version=4` enables path-prefix compression in the index.
|
|
+
|
|
* `core.untrackedCache=true` enables the untracked cache. This setting assumes
|
|
that mtime is working on your machine.
