2019-05-05lib/ui: fix Grid race conditionSimon Ser
This was is more complicated than others. The cells list is accessed by multiple goroutines: - Some change the Grid's contents via AddChild/RemoveChild - Some call Draw - Some invalidate the grid via Invalidate Invalidate calls are tricky to handle because they will also invalidate all child cells. This will inturn trigger the cellInvalidated callback, which needs to read the list of cells. For this reason, we use a sync.RWLock which allows multiple concurrent reads. Below is the race fixed by this commit.

2019-04-29lib/msgstore: protect with a mutexSimon Ser
MessageStore has a lot of exported fields that can be read from the outside. Each read must be protected, because a call from Update could happen at any time.
2019-04-29widgets/msglist: fix MessageList.store raceSimon Ser
This field could be written to in the middle of a Draw call, which reads it multiple times. Use an atomic variable instead.
2019-04-29worker/imap: use the IMAP connection from a single goroutineSimon Ser
Unfortunately, the IMAP protocol hasn't been designed to be used from multiple goroutines at the same time. For instance, if you fetch twice the same message from two different goroutines, it's not possible to tell whether the response is for one receiver or the other. For this reason, go-imap clients aren't safe to use from multiple goroutines. This commit changes the IMAP workers to be synchronous again (a command is executed only after the previous one has completed). To use IMAP from different threads, popular clients (e.g. Thunderbird) typically open multiple connections.

This release contains race conditions fixes.

2019-04-27lib/ui: introduce InvalidatableSimon Ser
Many Drawable implementations have their own Invalidate and OnInvalidate functions, with an unexported onInvalidate field. However OnInvalidate and Invalidate are usually not called in the same goroutine. This results in a race on this field, e.g.: Read at 0x00c000094748 by goroutine 7: git.sr.ht/~sircmpwn/aerc2/widgets.NewDirectoryList.func1() /home/simon/src/aerc2/widgets/dirlist.go:85 +0x56 git.sr.ht/~sircmpwn/aerc2/widgets.(*Spinner).Start.func1() /home/simon/src/aerc2/widgets/spinner.go:93 +0x1bb Previous write at 0x00c000094748 by main goroutine: [failed to restore the stack] Goroutine 7 (running) created at: git.sr.ht/~sircmpwn/aerc2/widgets.(*Spinner).Start() /home/simon/src/aerc2/widgets/spinner.go:46 +0x8f git.sr.ht/~sircmpwn/aerc2/widgets.NewDirectoryList() /home/simon/src/aerc2/widgets/dirlist.go:37 +0x286 git.sr.ht/~sircmpwn/aerc2/widgets.NewAccountView() /home/simon/src/aerc2/widgets/account.go:50 +0x5ca git.sr.ht/~sircmpwn/aerc2/widgets.NewAerc() /home/simon/src/aerc2/widgets/aerc.go:60 +0x800 main.main() /home/simon/src/aerc2/aerc.go:65 +0x33e To fix this, introduce a new type, Invalidatable, which protects the field. Unfortunately the Drawable must be passed to the callback function in Invalidate, so we still need to re-implement this in each Invalidatable user.
2019-04-27worker/types: fix Worker.Callbacks race conditionSimon Ser
Worker.Process* functions were called in different goroutines than Worker.Post*. Protect the map with a mutex. Also make the map unexported to prevent external unprotected accesses. Worker.Process* functions used to delete items from the map. However they didn't delete the element they retrieved: callbacks[msg.InResponseTo()] was read while callbacks[msg] was deleted. I'm not sure I understand why. I tried to delete the element that was accessed - but this broke everything (UI froze at "Connecting..."). I don't believe any elements were actually removed from the map, so the new code just doesn't remove anything.
2019-04-27widgets/spinner: fix Spinner.frame raceSimon Ser
It's accessed by the goroutine which increments it and the goroutine that draws the widget at the same time. Use atomic instead.
