I used to write commit message to connect issue system like issue #9548, redmine start page is fixed, and wonder whether it can be written in hook or plugin in gerrit system.
So in the code review page, the issue #9548 can be automatically show the http link to my issues system (like redmine): => issue#9548,redmine start page is fixed
It will be easily for code review.
Yes, it is possible. In your Gerrit configuration, you have to provide a regex expression for the string in the commit message and the link to your bugtracker with wildcards. See the Gerrit documentation. For your example, you would have a regex like (issue\s+#?)(\d+)
