Hi,


I originally imported the swift milestone-proposed branch  (lp:~hudson-openstack/swift/milestone-proposed) from launchpad into a git repository locally, sometime after the 1.4.1 release and synced again after the 1.4.2. This was before it was clear that the swift project was definitely moving to use git and the repo on github would definitely be the public git repo.


In looking to now switch to pulling from the project repo on github and I've noticed a few discrepancies.

Tag 1.4.1 within my local repo, which was imported from bzr, points to a different commit than what the github repository points to. I'm wondering how that has come to be?

github points to the following commit as being 1.4.1
$ git ls-remote openstack | grep refs/tags/1.4.1
9ab33970b58b8219245bfd89e2ad9442c0e94f17    refs/tags/1.4.1

Looking at the imported repo in git, I can see the following differences between what is tagged in github versus what was tagged in launchpad.

<snip 2 additional commits>

Commit d41490c38477205c6 merges the commit marked as 1.4.1 in github (9ab33970b58b82192) onto the milestone-proposed branch from launchpad.


I've looked at the tags from bzr on launchpad and confirmed that they point to same changes as my local tree for 1.4.1, so I'm wondering was the tag moved on launchpad sometime after the import into the github repository?


I see a similar thing happening with the 1.4.2 tag. What is tagged in github is not quite the same as the tag imported from launchpad. Also confirmed that the import of the tag from bzr to my local git repo is pointing to the same data, so it looks like the tags on launchpad for swift for 1.4.1 and 1.4.2 don't match what is tagged in github.

<snip commits to do with 1.4.1>

Commit a9c0a26 is what is tagged in github as the 1.4.2 release, but commit c4f718ff7c565 is what comes in with the import from launchpad using git-bzr-ng.

Also wondering if the milestone-proposed branch is getting deleted and recreated each time in github? Which would explain why each time I do comparisons it looks like the milestone-proposed branch in github doesn't share the same history after commit de49be3929d as the milestone-proposed branch in launchpad since ?


I also see odd things when looking at the glance repo on github, where the commit tagged for diablo-4 is not associated with any branch? Wondering if the same process resulted in that? This does have the effect of meaning you have to explicitly pull the tag in order to get the additional commits associated with it, as it doesn't get pulled across automatically with either of the two branches there.
