2019-05-19worker/types/worker: remove mutexSimon Ser
Worker.callbacks contains two types of callbacks: some are action callbacks, some are message callbacks. Each of those is access from one side of the communication channel (UI goroutine vs. worker goroutine). Instead of using a channel, we can use two different maps for each kind. This simplifies the code and also ensures we don't call an action callback instead of a message callback (or the other way around).
2019-05-19worker/types/worker: make ID allocation atomicSimon Ser
Message IDs are allocated for both messages from UI to workers and the other way around. Hence, the global nextId variable is accessed from multiple goroutines. Instead, use atomic to access the global counter.
2019-05-19worker/types/worker: set ID before sending messageSimon Ser
The previous code set the message ID after sending it, which could result in the receiver reading the ID before it's set.
2019-05-19lib/ui/ui: use atomic instead of channelSimon Ser
This makes it so an atomic `invalid` value is used instead of an unbuffered channel. When many invalidations kick in, a lot of values were sent to the channel. (Since OnInvalidate's callback can be run in any goroutine, we need to be careful about races here.)
2019-05-19Update internal state and draw from the same goroutineSimon Ser
This commit introduces a new Aerc.Tick function that should be called to refresh the internal state. This in turn makes each AccountView process worker events. The UI goroutine repeatedly refreshes the internal state before drawing a new frame. The reason for this is that many worker messages may need to be processed for a single frame, and drawing the UI is far slower than refreshing the internal state. This has been confirmed in my testing (calling Aerc.Tick only once per frame results in a slower display). Many synchronization code has been removed. We can now write widgets without having to care so much about races. The remaining sync users are: - widgets/spinner: the spinner value is updated from inside an internal goroutine - lib/ui/invalidatable: Invalidate may be called from any goroutine - lib/ui/grid: same - lib/ui/ui: an internal goroutine needs read access to UI.exit - worker/types/worker: Worker.callbacks is used for both worker and UI callbacks The exact goroutine requirements for Drawable have been documented.
2019-05-19Update go-imap and go-imap-idleSimon Ser
This fixes a race condition in go-imap-idle. See [1]. [1]: https://github.com/emersion/go-imap-idle/commit/2704abd7050ed7f2143753554ee23affdf847bd9
2019-05-19widgets/terminal: fix damage race conditionSimon Ser
Terminal.damage is accessed when drawing and when invalidating the widget. For this reason we need to protect it with a mutex. This seems to fix various damage issues I've been experiencing (where some regions of the terminal weren't correctly repainted).
