Bug Description

I just ran bzr shelve on a lightweight checkout, and am now unable to restore this shelved pack a few minutes later. The exact steps were

1) Working on a lightweight checkout using a local shared repository, but bound to a remote branch (in a remote shared repository), I did a bzr add, then bzr shelve --all
2) Switched to a new remote branch... didn't do anything with this
3) Switched back to the original branch and attempted to run bzr unshelve

At this point the following error was spat back out at me:

C:\Source\BondAdvance\bzr\working>bzr unshelve
Using changes with id "1".
bzr: ERROR: bzrlib.errors.NoSuchRevision: CHKInventoryRepository('file:///C:/Source/BondAdvance/bzr/.bzr/repository/') has no revision ('<email address hidden>',)

I've attached the shelf file for perusal. I would like this to remain a non-public bug for now though as the actual bundle itself contains some possibly sensitive material... though if I can find reproduction steps I will happily re-raise this in a new public bug.

I haven't tested for reproducibility yet... I have found this setup (as in multiple shared repo's) is causing some other issues though (I use bzr-svn, and have been bitten by quite a few bugs in the last few months... potentially the repo itself is in an inconsistent state somehow).

Ok... it *appears* as if the local shared repository missed out on a revision that was pushed to the remote branch. I ran a bzr up in the lightweight checkout, and this pulled in an extra revision that was present in the remote branch (and the remote shared repo), but not the local branch. I wonder if this is an issue in wider bzr potentially...

Hi Robert,

I would request that this bug report stays private without prior discussion with me. As stated in the description, some of the details and source snippets (though generally small and likely safe) I am not really under permission to release to the wide internet :)

Had discussions with various people finally so this has now been deemed abile to be revealed

As a workaround, you should be able to do 'bzr unshelve X --preview' and apply the resulting patch.
