Change in gerrit

Question

I am using gerrit for my project. I am automating some of my work which includes identifying the gerrit commit cherry-picked to local machine. for example: I have several changes uploaded on gerrit for review. I cherry picked those changes to local machine. Is there any way i can find out which changes are cherry picked and which are not?? I can compare revisions of cherry picked changes with the one on gerrit, but the problem is revision changes if parent changes.[revision is calculated by using different factors like diff,parent etc]

Which is the unique thing about gerrit change that doesn't change even if I cherry pick changes locally.

Answer 1

The Change-Id footer line in the commit message is unique for each commit (at least for a particular project/branch combo). The SHA-1 can't be used since it, as you've discovered, changes after a cherry-pick. To find the change id of an uploaded commit the query SSH command and /changes REST endpoint are useful.

Theoretically you could also use git cherry or git patch-id to compare commits, but I don't think it would be very practical in this case.
