Moved issue gerrit:5283 to now be  issue chromium:682001 .

What email is being sent to which address(es)? This may be a duplicate of  issue 680605 .

They're being sent to pdfium-reviews@. The previous bug was for the first upload. This behaviour is for subsequent pushes of the same CL which I don't think it was emailing about previously?

Aha, gotcha. I guess I still don't quite follow, though. These threads ([1], [2], [3], [4], [5]) don't contain any messages corresponding to later patchset uploads.

In particular, [1] contains the following messages:
1) Initial upload
2 & 3) Comment on PS2 (no notification of upload of PS2)
4) Comment on PS3 (no notification of upload of PS3)
5 & 6) Comment on PS4 (no notification of upload of PS4)
7) Change has landed

So I'm not sure which messages you're referring to that are sent upon upload and shouldn't be sent.

Like https://groups.google.com/d/msg/pdfium-reviews/fGuG79HchPQ/yXOUkergAQAJ for example.

Aha. That's on Gerrit, not git-cl, so would be a lot harder to change. You didn't upload patchset 3, you created it online by editing the commit description. That automatically triggers a message from within Gerrit itself.

I've filed a feature request (https://bugs.chromium.org/p/gerrit/issues/detail?id=5291) on the gerrit side for making this avoidable, but in the mean time I'm going to mark this WontFix. There are some features of Gerrit that people are going to have to adjust to.
