How to delete robot comments?

[Peter Bruin]

A bot generated a lot of lint warnings due to some errors in the commit. The errors are fixed but now the bot can not post anymore comments as the total would exceed 5000.

Is there a way to delete the comments from the previous patch-sets?

Thanks, 

Peter

If these are Gerrit robot comments (as opposed to normal comments posted by a robot) you can simply drop the refs/changes/<sharded-change-id>/robot-comments ref in the repo to delete all robot comments on the change.

Deleting normal comments requires rewriting the change meta ref and is possible via the Delete Comment REST endpoint [1], but doing it for that many comments might not be efficient. Maybe rather delete the change and create it newly.

Thanks Edwin,

I tried to delete the reference but ran into some access rights. As I didn't want to tinkle with the access rights I went for the easy way out and deleted the whole change and asked the user to push again. This resolved the issue.

Thanks!
