Delete all local changesets and revert to tree
dvcs, head, mercurial, version-control
Solution
When the simplest way (a new `hg clone`) isn't practical, I use `hg strip`:
% hg outgoing -l 1
% hg strip $rev # replace $rev with the revision number from outgoing
Repeat until `hg outgoing` stays quiet. Note that `hg strip $rev` obliterates `$rev` and all its descendants.
Note that you may have to first enable `strip` in your Mercurial settings.
PS: an even smarter approach is to use the revset language, and do:
% hg strip 'roots(outgoing())'
Problem
I'm using Mercurial and I've got into a terrible mess locally, with three heads. I can't push, and I just want to delete all my local changes and commits and start again with totally clean code and a clean history. In other words, I want to end up with (a) exactly the same code locally as exists in the tip of the remote branch and (b) no history of any local commits. I know `hg update -C` overwrites any local changes. But how do I delete any local commits? To be clear, I have no interest in preserving any of the work I've done locally. I just want the simplest way to revert back to a totally clean local checkout.
