Gerrit/Alternatives to git-review
If installing git-review is not feasible for you, you can use plain Git as well. This can sometimes be a better option if git-review doesn't suit your workflow.
Set up
Download the commit-msg hook script from gerrit:tools/hooks/commit-msg and save it in the .git/hooks/ subdirectory of your cloned copy of the repository.
There's three ways to do it:
Using curl
cd myrepo/
curl https://gerrit.wikimedia.org/r/tools/hooks/commit-msg > .git/hooks/commit-msg
Mark the file as as "executable". In Linux you can change this with:
chmod u+x .git/hooks/commit-msg
Using wget
cd myrepo/
wget -P .git/hooks https://gerrit.wikimedia.org/r/tools/hooks/commit-msg
Mark the file as as "executable". In Linux you can change this with:
chmod u+x .git/hooks/commit-msg
Using the web browser
Select "Save as..." from the context menu when right-clicking on this link: gerrit:tools/hooks/commit-msg
Save it to myrepo/.git/hooks/
Commit
Whenever you commit a change locally, the hook script will automatically add a unique "Change-Id" to the commit message.
Push for review
Add to following Git alias to simplify the command to push changes to Gerrit for review. You can do this by executing the following:
git config --global alias.push-for-review "push gerrit HEAD:refs/for/master"
If you have a single 'origin' remote, then in the above command replace 'gerrit' with 'origin':
git config --global alias.push-for-review "push origin HEAD:refs/for/master"
The refs/for/ part is a virtual branch prefix used by Gerrit.
However, you may replace "master" with another remote branch that you want to commit to.
E.g.: When trying to push to the remote branch Foo use refs/for/Foo.
Push a commit to Gerrit with:
git push-for-review
If you want to group a few related changesets (when working on a feature, or just to make them searchable in Gerrit), you can push them under the same topic using refs/for/Foo%topic=topic, for example:
git push gerrit HEAD:refs/for/master%topic=T12345
git push gerrit HEAD:refs/for/master%topic=my-feature
