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.

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.
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.
...so the backends don't have to do it.
Also added a stern warning about `org` being omitted, but leaving it as
allowed so as not to break existing apps (more than they are already broken,
at least).
Fixes#13322.
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.
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.
Fixes#13161.
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.
Fixes#13168.
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.
Fixes#13050.
It apparently works better (or can work better?) on multimonitor setups
than SwapBuffers.
This should be available back to Windows 95, but just in case, it falls
back to standard SwapBuffers if not available.
Fixes#13269.
On newer systems, the trick isn't necessary, and if you do it, if the user is
moving the mouse when launching the app, it'll show a hidden Dock.
Fixes#10340.
This is a special-case piece of functionality, generally these are expected
to go away during shutdown, but maybe someone is switching between audio
subsystems or something...
- 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.
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.
Fixes#12725.
You can't have two sections with the same name (so it can generate unique
page anchors), so fix one of these, and tweak another thing that _isn't_ a
header but wikiheader's quick-and-dirty parser thinks is one.
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.
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.
Fixes#12684.
So something like "index.pb" will now accept any file with a ".pb" extension,
to make macOS happy. This seems like a reasonable tradeoff.
Other minor cleanups.
Fixes#12778.
These events fire for other things, such as pressing a barrel button while
the pen is hovering.
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.
This info shows up in `pw-top` ...Gnome's sound preferences (etc) would
already show something more app-specific, but this command line tool shows
specific stream names.
Previously, we would WaitDevice first, but that would feed a silent buffer
to AAudio upfront, introducing latency. When this change was made, the
semaphore count should have been adjusted, since we're waiting on one less
buffer.
Fixes#12882.
- Add checks that ObtainPhysicalAudioDevice() was previously doing
(is subsystem initialized, is device valid).
- Remove optimizations that copy string to stack to release device_hash_lock
before SDL_GetPersistentString is called. Probably not necessary, and made
the code more complex.
These callbacks run in a thread we don't control, but might call SDL_SetError,
which will claim a TLS slot that never gets otherwise deallocated. To prevent
the leak, finish each callback by explicitly freeing any thread-local data.
Fixes#12732.
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.
Fixes https://github.com/libsdl-org/sdl2-compat/issues/367
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.
