Subject: [PATCH 1/2] commit-graph write: add progress output
Date: Tue,  4 Sep 2018 20:27:28 +0000
Message-ID: <20180904202729.13900-2-avarab@gmail.com> (raw)
In-Reply-To: <20180904202729.13900-1-avarab@gmail.com>

Before this change the "commit-graph write" command didn't report any
progress. On my machine this command takes more than 10 seconds to
write the graph for linux.git, and around 1m30s on the
2015-04-03-1M-git.git[1] test repository, which is a test case for
larger monorepos.

Furthermore, since the gc.writeCommitGraph setting was added in
d5d5d7b641 ("gc: automatically write commit-graph files", 2018-06-27),
there was no indication at all from a "git gc" run that anything was
different. This why one of the progress bars being added here uses
start_progress() instead of start_delayed_progress(), so that it's
guaranteed to be seen. E.g. on my tiny 867 commit dotfiles.git
repository:

    $ git -c gc.writeCommitGraph=true gc
    Enumerating objects: 2821, done.
    [...]
    Total 2821 (delta 1670), reused 2821 (delta 1670)
    Computing commit graph generation numbers: 100% (867/867), done.

On larger repositories, such as linux.git the delayed progress bar(s)
will kick in, and we'll show what's going on instead of, as was
previously happening, printing nothing while we write the graph:

    $ git -c gc.writeCommitGraph=true gc
    Annotating commits in commit graph: 1565573, done.
    Computing commit graph generation numbers: 100% (782484/782484), done.

Note that here we don't show "Finding commits for commit graph", this
is because under "git gc" we seed the search with the commit
references in the repository, and that set is too small to show any
progress, but would e.g. on a smaller repo such as git.git with
--stdin-commits:

    $ git rev-list --all | git -c gc.writeCommitGraph=true write --stdin-commits
    Finding commits for commit graph: 100% (162576/162576), done.
    Computing commit graph generation numbers: 100% (162576/162576), done.

With --stdin-packs we don't show any estimation of how much is left to
do. This is because we might be processing more than one pack. We
could be less lazy here and show progress, either detect by detecting
that we're only processing one pack, or by first looping over the
packs to discover how many commits they have. I don't see the point in
doing that work. So instead we get (on 2015-04-03-1M-git.git):

    $ echo pack-<HASH>.idx | git -c gc.writeCommitGraph=true --exec-path=$PWD commit-graph write --stdin-packs
    Finding commits for commit graph: 13064614, done.
    Annotating commits in commit graph: 3001341, done.
    Computing commit graph generation numbers: 100% (1000447/1000447), done.
