We have a code review repository where people hg push -f all sorts of stuff. After reviews are complete, we pull from the project's central repository, rebase, and push. I recently upgraded to mercurial 2.1 and get this message:
abort: can't rebase immutable changeset 43ab8134e7af
(see hg help phases for details)
when I try to hg pull --rebase from the central repository. How do I fix it?
In the review repository's .hg/hgrc file, add these lines:
[phases]
publish = False
The problem is due to a new feature in mercurial 2.1 called phases. It's great. Here is a nice introduction to its use.
To make the changesets in question mutable right now, use hg phase -f -d REV to force REV to be mutable again. Once the hgrc file has been changed, you shouldn't have to do that any more.
As a side note, hg push -f is lame. Make an alias hg review that pushes with -f to that repository.
