When Tom tries to verify me, it claims I rejected him, and that he rejected me. Neither is true #12479

Looking at the rageshake, it looks like there might be two VerificationRequest object monitoring the same request with the same transaction id. Doesn't look like a dupe of another bug.

In both requests, Matthew's client sent a second (and even third for request 2) .accept event which confused the hell out of both of Tom's and Matthew's client, upon which they both cancelled for the same reason.

bwindels · 2020-02-25T17:01:44Z

Looking into what's happening on Matthew's side before the second .accept gets send, there seems to be quite a bit megolm activity before.

bwindels · 2020-02-27T16:48:45Z

Have been investigating and still not sure why Matthew's client is sending 2 .accept events. He has reported several verification successes with other people since and will try to repro with Tom again.

Apart from waiting for more repros and having added more logging, not sure what else to do for now so parking this.

bwindels · 2020-02-28T18:30:53Z

This turned out to be Matthew's iOS client sending the second .accept, closing.

ara4n · 2020-02-28T18:32:17Z

Bruno & I just spent a while digging further into this, and spotted that the duplicate .accept()s are coming one from Chrome and the other from iOS.

In other words, Riot/iOS (on 0.110 - 20200221165108) was sitting in the background(?) sending rogue .accept()s. I thought we fixed this shortly after FOSDEM? :-/

@manuroe, @SBiOSoftWhare: is this a known issue? It's a really nasty failure mode :(

bwindels · 2020-03-03T17:20:57Z

Created an issue for Riot iOS, so this one can be closed.
