Barak Korren commented on OVIRT-1154:
-------------------------------------

We don't want to significantly slow down the CI because of this, a good guideline should be for the whole whitelist matching process to take:
# At most 1 network fetch (right not if fetches once via cloning from Gerrit)
# At most O\(n) time to search the match, where 'n' is the *number of contributors* as opposed to *number of patches*

AFAIK we don't keep lists of contributors anywhere ATM, so we'll probably need to scan patches to see who contributed. We may not be able to practically do this fast enough. We will need to check if Git or Gerrit can do this efficiently for us ahead of time. 

We also need some proper definition of who is considered a contributor. I don't think that someone with a merged patch ever is a good heuristic, should probably be something like N patches merged in the last M months.

> Right now our white list is based on a text file with email addresses in it. Its kinda silly when we already have lists and groups of users in Gerrit.
> Some suggestions:
> * make any members of a project's "maintainers" group automatically white-listed
> * make a specific group for other white-listed people
