We do have the commit mails and most of us read them, but sometimes not. It's
not really guaranteed that someone will review the code. Plus, it could be
too late once someone reads it since a build could have already gone through.
What about a process like this:
* Create new review branches for the active development trees. One for
rawhide, one for rhel4-branch, one for rhel5-branch. Whatever we need,
really:
master-review
rhel5-branch-review
rhel4-branch-review
Or some other names (rawrawhide, for example).
* If you want code reviewed by someone else before it goes in to the mainline,
commit it to the review branch for the release you're working on. A commit
mail will go out to everyone and we will also see code come in if we are
keeping local copies of the review branches (which we all should anyway).
* Establish review rules. Such as, you can't review your own code. Someone
else on the team reviews the patch on the review branch and if they like
it, cherry-pick it to the mainline and use the Signed-Off By feature of
git. That way we get two people to blame if a patch goes bad.
By using review branches to stage code, we can all continue to work at our on
pace and still get reviews from other people. We can at least ensure that
what gets built from rawhide is more stable...or at least looked at by two
people.
Using review branches also keeps the door open to emergency fixes that need to
go and we don't really have to change our processes for that.
Thoughts?
