Delete all local changesets and revert to tree

Question

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

Answer 1

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())'
