This is a brand-new thread to replace ds/early-access. The discussion on
that thread was very helpful [1].
With this in mind, I propose instead a set of "feature.*" config settings
that form groups of "community recommended" settings (with some caveats). In
the space below, I'll list a set of possible feature names and the implied
config options.
First, the main two categories we've discussed so far: many commits and many
files. These two feature sets are for when your repo is large in one of
these dimensions. Perhaps there are other settings to include in these?
feature.manyFiles:
index.version = 4
core.untrackedCache = true
feature.manyCommits:
core.commitGraph = true
gc.writeCommitGraph = true
(future: fetch.writeSplitCommitGraph = true)
Note: the fetch.writeSplitCommitGraph does not exist yet, but could be
introduced in a later release to write a new commit-graph (with --split) on
fetch.
The other category that has been discussed already is that of "experimental
features that we generally think are helpful but change behavior slightly in
some cases".
feature.experimental:
pack.useSparse = true
merge.directoryRenames = true
fetch.negotiationAlgorithm = skipping
Specifically, this setting is for config values we are not sure will ever be
on by default, but additional testing is needed to be sure. This is
different than a possible 'feature.preview' setting that would include
config settings that we are committed to updating the defaults in a future
release. There are many ways we can take this idea in the future (including
more additions to these categories).
Thanks, -Stolee
Updates in V2: I'm responding to Dscho's comments early, as they were very
valuable.
* Rearranged how we are checking for the feature.* settings, so if one
layer turns the setting on and a later layer turns it off, we do not
adjust the defaults.
* Switched to using enums for the non-boolean config options.
* Placed the repo_settings struct directly in the repository struct.
* All struct members are initialized to -1 using memset.
* The config changes around directory rename detection is greatly
simplified.
