Oops! This is my mistake. The correct command should be:
git show-ref -s | git graph --write --update-head --stdin-commits
Without "--stdin-commits" the command will walk all packed objects
to look for commits and then build the graph. That's why it's taking
so long. That method takes several minutes on the Linux repo, but with
--stdin-commits it should take as long as "git log >/dev/null".
Thanks, it took around 15m to finish with the command I initially ran on
my test repo.
Then the `merge-base --is-ancestor` performance problem I was
complaining about in
https://public-inbox.org/git/87608bawoa.fsf@xxxxxxxxxxxxxxxxxxx/ takes
around 1s with your series, 5s without it. Nice.
Thanks for testing this! May I ask how many commits are in your repo?
One way to find out is to run 'git graph --read' and it will tell you
how many commits are in the serialized graph.
Thanks,
