Improved SDL_PollEvent usage (#4794) 
* Avoid unnecessary SDL_PumpEvents calls in SDL_WaitEventTimeout

* Add a sentinel event to avoid infinite poll loops

* Move SDL_POLLSENTINEL to new internal event category

* Tweak documentation to indicate SDL_PumpEvents isn't always called

* Avoid shadowing event variable

* Ignore poll sentinel if more (user) events have been added after

227c33b8ec Add note about SDL_TICKS_PASSED hitting int overflow problems with large timeouts 2021-10-13 09:33:57 -07:00

1fa154fda3 Fix weak enforcement of timeouts in SDL_WaitEventTimeout_Device. This will loop pumping events and waiting for a system event to come in. However not all system events will turn into an SDL event. It's not unusual for a Windows message to be some internal thing that SDL doesn't convert into a message. In that case the loop will simple circle but not exit. As long as such messages are coming in the loop will continue to run regardless of the timeout. When messages finally stop it'll still wait for the full timeout so you can have arbitrarily long delays. 
Instead do an absolute elapsed time check since the start of the wait.  If that is exceeded during any iteration the routine exits as the timeout has elapsed.

2423c51471 Work around hang in AAudioStream_write() during extended shared object loading while running in a debugger. Observed on a OnePlus 8T (KB2005) running Oxygen OS 11.0.10.10.KB05AA. 
The observed behavior is that any nonzero timeout value would hang until the device was paused and resumed. And a zero timeout value would always return 0 frames written even when audio fragments could be heard. Making a manual timeout system unworkable.
None of the straightforward systems imply that there's a detectable problem before the call to AAudioStream_write(). And the callback set within AAudioStreamBuilder_setErrorCallback() does not get called as we enter the hang state.
I've found that AAudioStream_getTimestamp() will report an error state from another thread. So this change codifies that behavior a bit until a better fix or more root cause can be found.

40ed9f75c9 Workaround for Windows occasionally ignoring SetCursorPos() calls 
Also, since we're flushing mouse motion before and including the warp, we don't need the isWin10FCUorNewer hack to simulate mouse warp motion.

ad5205739e wayland: Only dispatch frame events in Wayland_GLES_SwapWindow 
Dispatching all events in Wayland_GLES_SwapWindow leads to resizes being
acked before the program has a chance to handle the resize. This change
reduces jumping on fullscreen transition with apps that call
SDL_PollEvent before issuing any render calls.
