notmuch/maildir: remove double emit of the dirinfo
There was some bug which could be worked around by double emitting an event. However that proofed to be brittle: We send the first message here from the worker goroutine: https://git.sr.ht/~sircmpwn/aerc/tree/a5553438/item/worker/maildir/worker.g= o#L306 Then Tick() is waked in the main goroutine and calls ProcessMessage: https://git.sr.ht/~sircmpwn/aerc/tree/a5553438/item/widgets/account.go#L100 ProcessMessage in the main goroutine reads types.Message state with msg.getId() and msg.InResponseTo(): https://git.sr.ht/~sircmpwn/aerc/tree/a5553438/item/worker/types/worker.go#= L74-76 Meanwhile in the worker goroutine we call PostMessage for a second time with a pointer that points to the *same* previous message that ProcessMessage is reading: https://git.sr.ht/~sircmpwn/aerc/tree/a5553438/item/worker/maildir/worker.g= o#L306 The second PostMessage call makes writes to message while ProcessMessage in the main goroutine is possibly reading: https://git.sr.ht/~sircmpwn/aerc/tree/a5553438/item/worker/types/worker.go#= L59 This led to a data race in the event loop Reported-By: Wagner Riffel <w@104d.net>
