Run "hg bisect -h". It's a method to track down the regression point
during changesets. A brief instruction is below:
- First, initizliaze
% hg bisect init
- Go to the broken point (usually the latest changeset, tip)
% hg update -rtip
- Mark it as bad
% hg bisect bad
- Go to the changeset that is known to work (e.g. v1.0.15)
% hg update -rv1.0.15
- Mark it as good
% hg bisect good
then the bisect will move to a next changeset to try.
- Try this changeset, and mark either good or bad.
- Repeat until the problematic changeset is found.
- Reset bisect
% hg bisect reset
Note that when you need an additonal patch, you have to apply the
patch at each time, and revert it (hg revert --all) before marking
