BzrCheckError: Internal check failed: revno does not match len(mainline) 714 != 0

[Matt Nordhoff]

While running "bzr check", I've gotten this error on several occasions, while it tries to check a branch.

On the first occasion, I was checking a remote (LP, in fact) repo/branch over bzr+ssh (yes, I know that's terribly slow). I tried to reproduce it afterwards but was unable to. It's possible the branch got written to while I was checking it.

Anyway, on this occasion, it happened on bzr.dev/bzrlib/plugins/bzrtools, which is a symlink pointing to a branch in a different repository, so obviously it can't just be checked in this repo. I'm pretty sure this one is reproducible, because I think I got it while checking the repo another time a few weeks ago.

bzr.dev r4459, Ubuntu 8.04.

If you can reproduce, please run with BZR_PDB=1 and poke around a bit.

Yeah, I can definitely reproduce it, just by doing "bzr check --branch
bzr.dev/bzrlib/plugins/bzrtools".

I have to admit, I've never used pdb before. I'm not against learning,
but it'd be faster if someone who is not me tried to do it. :-P

I've been checking bzrtools hundreds of times recently while I was
putting my check patch together. Never saw this.

It's not about bzrtools; it's about the symlink. (bzrtools does actually
pass if I check it directly.)

Steps to reproduce:

bzr init-repo a
bzr init-repo b
bzr init a/branch
bzr init b/branch
bzr ci --unchanged -m a a/branch/
bzr ci --unchanged -m b b/branch/
ln -s ../../b/branch a/branch/b
bzr check a
--

I have the same error message in one of my projects repository. The only different is that the 2 revno is the followwin 43!=44 When I am making a new commit both of those number will increase. How can I repair my repository?

[Martin Pool (mbp)]

Krisztian, 'bzr reconcile' should fix this.
