git / gerrit prevent develop branch to be merged into stable / testing branch

Question

Using Gerrit it is easy to accidentally merge unstable code from the develop branch into the stable branch:

$ git checkout develop
$ commit
$ git push origin HEAD:refs/for/stable

In Gerrit it isn't very clear that the proposed change comes from the develop branch and is to be merged into the stable branch. Is there a way to prevent this merge from happening, either in git or in Gerrit?

Update: For now we use a custom command to push to gerrit which finds the last branch in origin it was based on and only allow pushing to that branch.

Answer 1

Currently there are no options in software which would prevent You from making this kind of mistake.

There are, however, a few things You could do:

• train people, so they always check the branch name while performing a review
• set up a "pushed to correct branch" category (howto here) with options like +1 "Correct branch", 0 "No score", -1 "Incorrect branch", so the reviewer has to formally confirm that he checked the branch name
• set up a continuous integration tool to automatically review and score the aforementioned category (Jenkins has a plugin You could use)

Would You share the custom command You use to push to gerrit, please?
