* lib/ui: introduce InvalidatableSimon Ser2019-04-2712-127/+82
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* worker/types: fix Worker.Callbacks race conditionSimon Ser2019-04-272-21/+42
| | | | | | | | | | | | | 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.
* widgets/spinner: fix Spinner.frame raceSimon Ser2019-04-271-12/+15
| | | | | | | | | | | | | | | | | | | | | | | | It's accessed by the goroutine which increments it and the goroutine that draws the widget at the same time. Use atomic instead.

| | | | | | | | | When changing to an empty directory, ml.selected is 0, and the length of ml.store.Uids is 0. The loop condition is always true so we have an infinite loop causing 100% CPU usage and prevents us to change to other directories. Signed-off-by: Tom Lebreux <tomlebreux@cock.li>
