Occasionally when performing a rebase using the MercurialEclipse plugin my repository gets thrown into an odd state. It will become stuck in a “rebasing” state, yet when I try to abort the rebase (e.g. “hg rebase -a”) I get this error message:
abort: unknown revision ‘xxxx‘!
Where xxxx is a revision hash. Usually at this point I’ve abandoned all hope of performing the rebase — I just want to get back to a happier time when my repository was not screwed up. So far my solution has been to nuke my project directory and clone it again. Is there a less drastic solution?
Just remove the .hg/rebasestate and your repo will work.
The patch described in this thread calls the internal function clearstate which just unlinks this file.
