Integration with Git
Add Gerrit as one of your remotes
You will want to add Gerrit as a remote, using the username you selected in the Gerrit web interface,
git remote add gerrit USERNAME@review.source.kitware.com:ITK
Gerrit allows you to select a username, and to upload your public SSH key(s).
How to push to Gerrit
When on your topic branch, to view the commits that will be pushed as changes,
git fetch gerrit git log gerrit/master..
Then, when you have a topic branch ready to go,
git push gerrit HEAD:refs/for/master/topic-name
(Note: this could be simply
git gerrit-push
if you have run SetupForDevelopment.sh)
Each of the commits listed by git log will then show up as a commit, optionally labeled with topic-name, in the Gerrit web interface. These commits can then be reviewed and integrated.
Making Changes in Uploaded Patches (Hard way)
If your change requires revision before it is accepted, you will first need to correct the commit in the topic branch. The change-id should have been automatically added to your commits, or you can manually add it after the fact if necessary.
git rebase -i HEAD~2
An editor will open, see here for details on interactive rebasing. Once you have edited the relevant commit(s) you should be ready to upload the updated patches, assuming your commit messages all have the last line,
Change-Id:[change id from Gerrit here]
You can then push the corrected commit(s) to Gerrit,,
git push gerrit HEAD:refs/for/master/topic-name
This updated patch will be shown in the interface as patch set 2, any subsequent commits in the topic should also be updated with their new parents being the updated commits.
Making Changes in Uploaded Patches (Easy way)
If your change requires revision before it is accepted, you will first need to correct the commit in the topic branch. To do this:
git add
any files that have changed.
Then
git commit --amend
An editor will open. You can edit the commit message if necessary. Then
git gerrit push
This updated patch will be shown in the interface as patch set 2, any subsequent commits in the topic should also be updated with their new parents being the updated commits.
