commit-graph write: add itermediate progress
Add progress output to sections of code between "Annotating[...]" and "Computing[...]generation numbers". This can collectively take 5-10 seconds on a large enough repository. On a test repository with I have with ~7 million commits and ~50 million objects we'll now emit: $ ~/g/git/git --exec-path=$HOME/g/git commit-graph write Finding commits for commit graph among packed objects: 100% (124763727/124763727), done. Loading known commits in commit graph: 100% (18989461/18989461), done. Expanding reachable commits in commit graph: 100% (18989507/18989461), done. Clearing commit marks in commit graph: 100% (18989507/18989507), done. Counting distinct commits in commit graph: 100% (18989507/18989507), done. Finding extra edges in commit graph: 100% (18989507/18989507), done. Computing commit graph generation numbers: 100% (7250302/7250302), done. Writing out commit graph in 4 passes: 100% (29001208/29001208), done. Whereas on a medium-sized repository such as linux.git these new progress bars won't have time to kick in and as before and we'll still emit output like: $ ~/g/git/git --exec-path=$HOME/g/git commit-graph write Finding commits for commit graph among packed objects: 100% (6529159/6529159), done. Expanding reachable commits in commit graph: 815990, done. Computing commit graph generation numbers: 100% (815983/815983), done. Writing out commit graph in 4 passes: 100% (3263932/3263932), done. The "Counting distinct commits in commit graph" phase will spend most of its time paused at "0/*" as we QSORT(...) the list. That's not optimal, but at least we don't seem to be stalling anymore most of the time. Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
