            Bug ID: 3603
                CC: mercurial-devel at selenic.com
          Assignee: bugzilla at selenic.com
           Summary: Unexplained repository corruption
          Severity: bug
    Classification: Unclassified
                OS: Mac OS
          Reporter: csutton at inf.ed.ac.uk
          Hardware: Macintosh
            Status: UNCONFIRMED
           Version: unspecified
         Component: Mercurial
           Product: Mercurial

I have a roughly ~800MB repo that I have used for about 3 years. I am the only
user, but I keep one clone on my Mac laptop and one clone on a remote Linux
machine. I pretty much do all my work on the Mac clone and push to the remote
clone. On Mac I am currently using hg version 2.3 and on Linux 2.1. (Didn't
realize the version mismatch until I prepared this bug report; maybe that's not
so good.)

I committed some changes that were intended to move some directories around the
repo. Then when I pushed I got:

I didn't intend to commit a .DS_Store file but it is possible that I did so
inadvertently. Some Googling led me to the verify command. On the Mac repo this
returns

[csutton hg] :; hg verify

I am sending a bug report because the software asked me to do so. My questions
are: Did I do something wrong? Am I totally screwed? Is there any way to
recover? Thanks for any help that you're able to provide...
