My question is whether anyone is actually using the labels? I realize they are somewhat redundant when we are also adding the title part. The labels are also a friction point with cherry-picker.py as the script can't set those automatically like it can the PR title. So I'm thinking that maybe we should drop the labels? Anyone have an opinion or want to say if they use the labels and how they use them?

I haven't seen a particular use for them - the "needs backport" ones are useful as a marker for what still needs backporting, but nothing changes in the process based on whether or not a maintenance branch PR is a cherry-pick or not.

Sorry, I didn't mean to suggest that I thought the "needs backport to *" labels should go, my question is about the "cherry-pick for *" labels only.

If all of these become automated, then perhaps cherry-pick labels aren't needed.

The "needs backport *" labels will still be needed even in that instance probably for when a backporting PR fails (e.g. merge conflict that requires a human being to resolve).

There should still be a bot that removes the `needs backport` label. It will simplify this issue https://github.com/python/bedevere/issues/13

Which we are actively discussing. :) -Brett

OK then it seems like the there is no real need to apply `cherry-pick for *` anymore? +1 from me for not having to apply `cherry-pick for *` label. I can update cherry_picker.py readme and the devguide, if we're all ok with it :) what's probably more important is the backport PR

title pattern of: [X.Y] <whatever> (GH-<PR number>)

Yes, cherry_picker.py does this for you :) In the devguide though, we've only instructed people to prefix it with [X.Y], but did not mention about `GH-<PR number>`. I'll open an issue. Thanks :) Mariatta Wijaya On Tue, May 9, 2017 at 7:17 PM, Nick Coghlan wrote:

For that purpose, what's probably more important is the backport PR title pattern of:

[X.Y] <whatever> (GH-<PR number>)

The fact it's a cherry-pick is implied by the reference to the original PR (also indicated by the git cherry-pick message in the commit body), while the [X.Y] indicates which branch it's for.

The labels are also going to convey strictly less information than that, since they won't indicate the original PR number or the cherry-picked commit hash.

Cheers, Nick.
