           Summary: abort: unknown revision when pulling a bookmark
                    associated with a hidden changeset
          Severity: bug
    Classification: Unclassified
                OS: All
          Reporter: gregory.szorc at gmail.com
          Hardware: All
            Status: UNCONFIRMED
           Version: unspecified
         Component: Mercurial
           Product: Mercurial

This bug is similar in nature to bug 4075 in that things blow up when
attempting to push/pull when hidden changesets are involved.

I had a non-publishing repository where I was pushing bookmarks so I could
access things on separate devices. Somehow I managed to create a bookmark on
the server that was pointing to a hidden/obsolete changeset. When I attempted
to pull that repo, the client aborted:

$ hg pull collab
pulling from ssh://hgssh@hg.gregoryszorc.com/gecko-collab

adding remote bookmark gps/build/generic-build-rule
adding remote bookmark gps/build/gyp-dependencies
adding remote bookmark gps/build/jarmaker-api
adding remote bookmark gps/build/js-modules-install-manifests
abort: unknown revision '4eb57fd5292afdb2b547a0ca1354ea9ab825447f'!

I confirmed the changeset in question existed, but was hidden:

$ hg log --hidden -r 'hidden() and 4eb57fd5292afdb2b547a0ca1354ea9ab825447f'
changeset:   170469:4eb57fd5292a
parent:      170304:6c06b499bb16

I'm trying to come up with STR. The simple case of setting a bookmark to an
obsolete/hidden changeset and then pulling that repo from local fs doesn't seem
to be triggering this...
