Subject: [PATCH 0/3] builtin/commit-graph.c: new split/merge options
Date: Thu, 30 Jan 2020 16:28:14 -0800 [thread overview]
Message-ID: <cover.1580430057.git.me@ttaylorr.com> (raw)
Hi,
Here are another few patches that came out of working on GitHub's
deployment of incremental commit-graphs. These three patches introduce
two new options: '--split[=<merge-all|no-merge>]' and
'--input=<source>'.
The former controls whether or not commit-graph's split machinery should
either write an incremental commit graph, squash the chain of
incrementals, or defer to the other options.
(This comes from GitHub's desire to have more fine-grained control over
the commit-graph chain's behavior. We run short jobs after every push
that we would like to limit the running time of, and hence we do not
want to ever merge a long chain of incrementals unless we specifically
opt into that.)
The latter of the two new options does two things:
* It cleans up the many options that specify input sources (e.g.,
'--stdin-commits', '--stdin-packs', '--reachable' and so on) under
one unifying name.
* It allows us to introduce a new argument '--input=none', to prevent
walking each packfile when neither '--stdin-commits' nor
'--stdin-packs' was given.
Together, these have the combined effect of being able to write the
following two new invocations:
$ git commit-graph write --split=merge-all --input=none
$ git commit-graph write --split=no-merge --input=stdin-packs
to (1) merge the chain, and (2) write a single new incremental.
Thanks in advance for your review, as always.
