问题
The rebase extension to mercurial provides functionality similar to git's rebase.
Letting the rebase execute takes something like 4 minutes (~240 s) for 100 commits.
In my imagination this should be extremely fast, a few seconds at most, but clearly I'm missing something.
What makes it take so long? Are the commits themselves just extremely expensive?
回答1:
By default, rebase writes to the working copy, but you can configure it to run in-memory for better performance, and to allow it to run if the working copy is dirty.
Just add following lines in your .hgrc file:
[rebase]
experimental.inmemory = True
(To get more configuration for rebase try to run hg help rebase)
