Ryan C. Gordon 5b688514c7 wikiheaders: Don't autolink things that are already linked.
This is a dirty hack, but it currently works for our purposes. We just refuse
to link an eligible string (like, say...`SDL_shadercross`), if there's a '['
character right before it.

This WILL NOT WORK if the string is in the middle of a link! For example, if
you had `[please refer to SDL_shadercross](https://example.com/)`, this will
still fail in the usual ways, but we're not building out a robust parser here
at the moment, and this catches the most common problem.

Fixes #13160.

Ryan C. Gordon c80d6954cb Revert "audio: Added SDL_SetAudioIterationCallbacks()."
This reverts commit 608f706a95.

Didn't end up using this in SDL3_mixer, and it's a super-awkward API if we
don't need it.

I _might_ bite the bullet and let people lock a physical audio device, though,
as I could see that being useful but less awkward for the same reasons I
originally wanted it.

Ryan C. Gordon 07ef532681 hints: Renamed SDL_HINT_LOG_BACKENDS to SDL_DEBUG_LOGGING.
This still logs backend choices, but we might use it for other things. For
example, what Android device is being used, or all the devices we enumerated,
etc.

Ideally this eventually logs all the stuff we often have to ask followup
questions about.

Ryan C. Gordon af1c05fd58 filesystem: Check SDL_GetPrefPath parameters at the higher level.
...so the backends don't have to do it.

Also added a stern warning about `org` being omitted, but leaving it as

at least).

2025-07-15 20:36:56 -04:00
Ryan C. Gordon f2ae6503c0 audio: Binding an SDL_AudioStream will set missing formats.
It _must_ have the format set for the opposite side from the device (so
playback needs the src format set, and recording needs the dst format set),
since the stream gets mangled by the device thread if not. So if it has never
been set (stream created with NULL audiospec), just set it to match the device.
If the stream is just meant to buffer and not convert, this is desired
behavior, even if it didn't also fix a bug.

Binding the audio stream will always set the device side's format, as usual;
this does not need to be set by the caller at all.

Fixes #13363.

2025-07-13 21:40:42 -04:00
Ryan C. Gordon 536126fdcf emscripten: Move over to using Pointer Events for all mouse, pen, and touch.
This allows us to avoid browser mouse emulation for touches, since we provide
our own anyhow.

The other option is to "prevent default" in the legacy touch event handlers we
historically used, to tell the browser not to supply emulation, but we can't
currently tell Emscripten to mark those handlers as not "passive," so as it
stands they are unable to prevent default. Using Pointer Events bypasses this
problem entirely.

Ryan C. Gordon 9af93abd4f cocoa: Don't minimize fullscreen windows for a modal file dialog.
macOS sends a focus loss event when the dialog is created, which causes SDL
to try to minimize the window, which confuses the entire system. So in this
special case, don't do the minimization.

Ryan C. Gordon 515433aa8a android: If various POSIX fsops functions fail, try using AAssetManager.
This specifically affects SDL_EnumerateDirectory and SDL_GetPathInfo. Android
assets are read-only, so no need to do this for things like
SDL_CreateDirectory, etc, and the POSIX SDL_CopyFile() uses SDL_IOStream
behind the scenes, which already supports Android assets.

Ryan C. Gordon f286558bae windows: Use wglSwapLayerBuffers if available.

back to standard SwapBuffers if not available.

- Check for specific availability instead of waiting for "device ready."
- Don't use snd_pcm_wait, just use a simple SDL_Delay (nothing to recover).
- Fixed SDL_max call that should have been SDL_min (now using SDL_clamp).
- ALSA_RecordDevice() now returns 0 if no availability, which kicks us back
  to WaitDevice to try again, as an extra safety check.

Ryan C. Gordon f61d956a04 cocoa: add explicit tracking areas to the window.
This makes sure we get reliable mouse enter/exit events from the system on
older macOS releases.

Newer releases don't have this problem--my assumption is that Cocoa has a
more aggressive default tracking area installed for some newer UI feature.

For 3.2.16, we'll use the explicit tracking area on older macOSes only, but
I'll remove that check in revision control for newer OSes and see what
happens.

Ryan C. Gordon 795d1ae1fb testmessage: Don't push the event if "Retry" was chosen.
Otherwise, the message box thread goes back to blocking, but the app's main
thread progresses to SDL_WaitThread and won't pump the event queue anymore.

On iOS, this means the messagebox won't pop back up (because it uses
SDL_RunOnMainThread, which needs the event loop to pump), but it's just bad
practice on any platform to stop pumping the event queue for indefinite
lengths of time.

Ryan C. Gordon 57346f2ba8 dialog: Cocoa backend should reactivate the app after the modal dialog.
Otherwise the window won't have focus until you click on it again. Calling
makeKeyAndOrderFront isn't enough to fix it, either.

This trick comes from a similar problem we solve in our
applicationDidFinishLaunching implementation: activate (give app focus to) the
system Dock, as something that definitely exists that isn't us and is harmless
to activate, and then activate us right afterwards. This unconfuses whatever
is getting confused inside Cocoa.

The correct thing to do is check IS_POINTER_INCONTACT_WPARAM in the event.

If the pen is already touching or not, SDL_SendPenTouch() will do the right
thing, so it's safe to call it even if we're already in the right state.

Ryan C. Gordon b00b08f832 touch: Keep state correct when removing virtual touch devices during quit.
This is probably not strictly necessary, since SDL_InitMouse will zero out
the whole struct to start if SDL is reinitialized, but just in case.

Ryan C. Gordon 4c035a1fd8 audio: Allow PipeWire and PulseAudio streams to migrate to other sinks.
SDL still manages hotplug and default device management here, but if a user
wants to use an external tool, such as `pactl move-sink-input`, to put it
onto a different device, they probably know what they're doing and we
shouldn't stop them.

If this turns out to have some unexpected consequences, though, we can revisit
the change.

Ryan C. Gordon ae17b04c0d alsa: Don't start the hardware until the device thread is ready to do work.
Otherwise, in the time it takes the thread to start and other init tasks to
complete, we tend to get an underrun on some systems, which ALSA logs to
stderr.

So this is moved to an InitThread implementation, which runs from the device
thread, right before it begins its main loop.

Ryan C. Gordon 41636959d2 audio: Feed output devices immediately, instead of waiting upfront.
This prevents the waste of an initial buffer of audio on many backends, and is
hopefully harmless on all of them.
