error NoSuchRevision during update

[Mikael Andersson]

A trunk and feature branch were created in a shared repository. An Update of the feature branch resulted in the error below.

The following actions were done in Bazaar Explorer:

Created a shared repository with a trunk branch.
Created a feature branch which I bound to the trunk.
Created three files: a.txt, b.txt and c.txt in the trunk.
Added and commited above files.
The files were then pulled into the feature branch.

The rest of the actions, I do not remember, but I hope the details are clear from the trace below.

Run command: bzr update -r revid:<email address hidden>
All changes applied successfully.
bzr: ERROR: bzrlib.errors.NoSuchRevision: BzrBranch7(file:///C:/Bazaar%20test/repository/test_feature/) has no revision <email address hidden>

I'm going to tentatively reassign this to qbzr, as I think the cause may be there rather than bzr itself: it appears that qbzr is specifying a revision ID to 'bzr update' that isn't in the ancestry of the branch, which causes this error. Perhaps it is trying to update a working tree of the test_feature branch to a revision only found in the ancestry of the trunk branch?

I'm not certain the root cause isn't bzr itself, so please feel free to assign it back if you think I'm wrong.

[Gary van der Merwe (garyvdm)]

The only way that qbzr automatic adds a -r parameter to update, is when using the qlog "Update to this revision" feature. But using that, I was only able to get this error:

Run command: bzr update -r revid:<email address hidden>
bzr: ERROR: branch has no revision <email address hidden>
bzr update --revision only works for a revision in the branch history

Anyway, qlog should not give you the option "Update to this revision" for revisions that are not ancestor of the branch tip.

Mikael: if I have correctly diagnosed what happened, then you are trying to update in the wrong way. To do what I think you want, just click on the "Update" option in Bzr Explorer.
