[llvm-dev] FYI: LLVM Phabricactor notifications.

Mon Jun 3 04:24:40 PDT 2019

Hi David,

No, these are Phabricator emails, for a recent example see D62616 which was originally subscribed only to cfe-commits, but then in the final Phabricator email after committing we see:

This revision was automatically updated to reflect the committed changes.
Closed by commit rL362363: [CodeComplete] Add a bit more whitespace to completed patterns (authored by ibiryukov, committed by ).
Herald added a project: LLVM.
Herald added a subscriber: llvm-commits.

There's no reason for Herald to be adding project LLVM/subscriber llvm-commits at the last second here.

I am curious how this plays with what I reported in PR41996. It would be sad if Clang commits were reported to the llvm-commits list, and not cfe-commits.

I'm guessing that the commit mails you're thinking of are not from Phabricator, but rather directly from the SVN post-commit hook. Those are not affected.

The ones that would be different now are the ones with something like "[PATCH] D123456" in the subject line, or "[Diffusion] rL123456", where rL is the callsign. You'll still get emails for callsigns rG and rL, but those (already) generally only go to the committer, and will also get the replies if you comment on the commit through the Phabricator UI.

I tweaked the notifications yesterday, hopefully we don't see more spam storms.

For filtering git refs: this is something that has changed substantially in Phabricator over the past couple of months, but I think I've managed to restrict notifications to only "master." (Although, again, this has changed a lot... getting this right depends on my own archaeological skills for digging through old revisions of the Phab documentation.)

There are some complicating factors in deciding what the notifications should actually be doing... one major source of complexity stems from the fact that we re-import most commits multiple times. This makes it hard to reason about how different notifications will fire, and which source will actually autoclose differential revisions.

The current state is that most commits should notify the committer twice: once for the Subversion repo (repo callign rL), and once for git master (rG). I think this may actually be the best state while we're living in both worlds: the SVN commit is the source of truth, but a lot of folks care about re-syncing from Git, so that also seems like something folks will want. Of course, this is a transitional pain point, and there's not going to be a single configuration that can satisfy every possible thing folks would want.

One particular change: I've disabled notifications for the duplicate Subversion meta-repos... so, for example, a commit to Clang will still get 2 notifications (rL and rG). Before yesterday, this should have sent 3: one each for rL, rG, and rC. Projects not in the monorepo will get notifications for rL only.

I also follow the Phabricator development quite closely because we upgrade every couple of weeks

I’d be more than happy to help maintain the phab instance for LLVM

Congrats. You're now an admin :)
(and thanks!!)

I'll figure out who easy it is to give access to our GCE to external folks, given everything on it is OSS stuff.

(Provocative offtopic. (I personally hope that never ever happens.))

Strong +1 to not switching away from phab.

Aaron, do you have admin on phab yet? If yes, would you mind to config the notifications?
(honestly, part of my comment was trying to figure out who wants it so badly that they'd be willing to help with maintenance - I have admin bits to hand out :)
