Subject: [PATCH v3 10/10] commit-graph write: emit a percentage for all progress

From: Ævar Arnfjörð Bjarmason <[email-masked]>
Date: Thu, 22 Nov 2018 13:28:23 +0000

Change the "Annotating commit graph" progress output to show a
completion percentage. I added this in 7b0f229222 ("commit-graph
write: add progress output", 2018-09-17) and evidently didn't notice
how easy it was to add a completion percentage.

Now for the very large test repository mentioned in previous commits
we'll emit (shows all progress output):

    Finding commits for commit graph among packed objects: 100% (48333911/48333911), done.
    Annotating commit graph: 100% (21435984/21435984), done.
    Counting distinct commits in commit graph: 100% (7145328/7145328), done.
    Finding extra edges in commit graph: 100% (7145328/7145328), done.
    Computing commit graph generation numbers: 100% (7145328/7145328), done.
    Writing out commit graph in 5 passes: 100% (35726640/35726640), done.

And for linux.git:

    Finding commits for commit graph among packed objects: 100% (6365442/6365442), done.
    Annotating commit graph: 100% (2391666/2391666), done.
    Computing commit graph generation numbers: 100% (797222/797222), done.
    Writing out commit graph in 5 passes: 100% (3986110/3986110), done.
