Hi all,after the recent switch to GitHub, I've seen that reviews that require multiple iterations are hard to follow using the old workflow we were using in Gerrit.Till now we basically amended the commit and pushed it again. Gerrit had a feature to calculate diffs between versions of the patch, so it was relatively easy to follow the changes between iterations (unless there was a big change in the base branch and the patch was rebased).In GitHub we don't have this feature (at least I haven't seen it). So I'm proposing to change this workflow.The idea is to create a PR with the initial commit. When a modification needs to be done as a result of the review, instead of amending the existing commit, we should create a new commit. From the review tool in GitHub it's very easy to check individual commits.

Once the review is finished, the patch will be merged with the "Squash and Merge" option, that will combine all the commits into a single one before merging, so the end result will be exactly the same we had with Gerrit.

Just a note to the maintainers who are merging PRs to have patience and check the commit message when there are more than 1 commits in PR.
Another thing to consider is that rfc.sh script always does a rebase before pushing changes. This rewrites history and changes all commits of a PR. I think we shouldn't do a rebase in rfc.sh. Only if there are conflicts, I would do a manual rebase and push the changes.
With github workflow, we don't need './rfc.sh' in my personal opinion. I ported it to new branch and github considering the number of developers who are used to it. If you do the changes as per github, then you would have a separate branch per PR (ie, feature/bug), so you are at your own to decide when to rebase.
What do you think ?
I agree, we can remove -f option of ./rfc.sh and also the rebase part in ./rfc.sh!

Amar
