76f48acf63 audio: threading and device hang improvements.
This tries to make SDL robust against device drivers that have hung up,
apps don't freeze in catastrophic (but not necessarily uncommon) conditions.

Now we detach the audio thread and let it clean up and don't care if it
never actually runs to completion.

bac61096d8 ensure SDL_AUDIODEVICEREMOVED gets sent when hotplug removes a device
James Zipperer

The problem I was seeing was that the the ALSA hotplug thread would call SDL_RemoveAudioDevice, but my application code was not seeing an SDL_AUDIODEVICEREMOVED event to go along with it.   To fix it, I added some code into SDL_RemoveAudioDevice to call SDL_OpenedAudioDeviceDisconnected on the corresponding open audio device.  There didn't appear to be a way to cross reference the handle that SDL_RemoveAudioDevice gets and the SDL_AudioDevice pointer that SDL_OpenedAudioDeviceDisconnected needs, so I ended up adding a void *handle field to struct SDL_AudioDevice so that I could do the cross reference.

Is there some other way beside adding a void *handle field to the struct to get the proper information for SDL_OpenedAudioDeviceDisconnected?

2558c9c836 fix audio deadlock
James Zipperer

Close the audio device before waiting for the audio thread to complete, which fixes a situation where the audio thread never completes

Add an additional check in the audio thread to see if the device is enabled and bail out if the device is no longer enabled

a21a227a87 Fixed bug 3021 - HapticOpenFromJoystick() problems
Joe Thompson

With Direct Input device (MOMO Steering Wheel w/FF)
with SDL 2.0.3,
SDL_HapticOpenFromJoystick() would fail. (Can't set exclusive mode)
Now with 2.0.4 rc1,
SDL_HapticOpenFromJoystick() succeeds but the the returned SDL_Haptic* cannot be used. Calls to SDL_HapticNewEffect() fail with "Haptic error Unable to create effect"

If SDL_HapticOpen() is used instead of HapticOpenFromJoystick(), the device is usable. Calls to HapticNewEffect() succeed with the exact same parameters as the previous failing call.

I have attached a proposed patch for this issue.

When using SDL_HapticOpenFromJoystick(), the original code did not (re)enumerate the axes. This returned a new haptic device with 0 axes. Later, when a new effect is created, SDL_SYS_SetDirection() would set the flags to include DIEFF_SPHERICAL, regardless of what the caller actually set. (see Line 566 in SDL_dinputhaptic.c). This would cause the SDL_HapticNewEffect() to fail (or interpret the coordinates incorreclty.)

The patch moves the call to IDirectInputDevice8_EnumObjects() outside of the if() block so that the axes are (re)enumerated for the new haptic device.

Note: For steering wheels it is common for the joystick to have multiple axes (ie steering, throttle, brake), but the haptic portion of the joystick usually only applies to steering.

46f44f66f8 Fixed potential buffer overflow in SDL_vsnprintf() (thanks, Taylor!).
Fixes Bugzilla #3441.

"When using internal SDL_vsnprintf(), and source string length is greater
than destination, the final NULL char will be written beyond destination size.

Primary issue that is SDL_strlcpy returns length of source string
(SDL_PrintString()), not how much is written to destination. The destination
ptr is then incremented by this length before the sanity check is done.
Destination string is properly terminated, but an extra NULL char will be
written beyond destination buffer length.

Patch used internally is attached which fixes primary issue with SDL_strlcpy()
in SDL_PrintString() and adjusts sanity checks to increment destination ptr
safely."

351adf156a Fixed bug 2157 - Caps Lock key produces key down & key up events while key is still pressed.
Tim McDaniel

Using checkkeys test app:
* Press and hold Caps Lock key.
* checkkeys reports a CapsLock key pressed event and a CapsLock key released event.
* Release Caps Lock key.
* checkkeys reports no further events.

This patch fixes OSX Caps Lock up/down event detection by installing a HID callback.

4e6f219941 Fixed bug 3065 - Screen is flickering during closing on-screen keyboard on Android
Deve

When I'm trying to close on-screen keyboard using SDL_StopTextInput() function by touching the screen (SDL_FINGERUP or SDL_FINGERDOWN event), the screen is flickering. It is white for a while.

Note that it usually works without problems when I use phone's "back" button. I noticed flickering occasionally too, but not that often.

Philipp Wiesemann

The attached patch maybe fixes the flicker but not the actual fault causing it.

fae5d0eab3 Fixed bug 3107 OSX - Process events in SDLApplication to fix integration with CEF.
John Wordsworth

While attempting to integrate CEF (Browser) into an SDL application, we noticed that there were problems on OS X where approximately 50% of the input events were essentially being lost - even when we were using off-screen rendering in CEF and passing through input events manually.

It appears that this problem has been around for a while (see: http://www.magpcss.org/ceforum/viewtopic.php?f=6&t=11141).

Please consider the following patch that fixes this issue. Instead of processing events directly after calling [NSApp nextEventMatchingMask:...] we now pass these events down to NSApp, for processing by an overloaded sendEvent: method. Chromium also forwards events to NSApp in the same way, which means we don't miss events, even if they were originally dequeued by CEF.

Seems like check of the visibility of renderer (renderer->hidden) is missing in SDL_RenderCopyEx.

In SDL_RenderCopy it should be done much earlier (after checking support for RenderCopyEx, line 1750).

0250eb3c4f Fixed bug 3134 - CalculateXRandRRefreshRate() returns incorrect refresh rate due to floating point truncation.
Michael

In SDL_x11modes.c the CalculateXRandRRefreshRate() function performs integer math on values that may return fractional results. This causes a value that would be calculated as 59.99972... to be returned as 59. In Linux the xrandr command returns 60Hz for this particular display mode yet SDL returns 59Hz.

I suggest this function be updated to correctly round the result of the calculation instead of truncating the result.

64180d2261 Fixed bug 3138 - c_dfDIJoystick2 already defined in dinput8.lib
Machiel van Hooren

In SDL_dxjoystick.c line 349 there is a constant c_dfDIJoystick2.
However, this constant is aparently also defined in dinput8.lib.

I encountered a linking error when statically linking to SDL:
SDL2_static.lib(SDL_dxjoystick.obj) : error LNK2005: _c_dfDIJoystick2 already defined in dinput8.lib
My application is also linking to dinput8.lib because we rolled our own joystick input and are not using the joystick functionality from SDL.

1a31bbe2c8 Fixed bug 3157 - Rudimentary touchscreen support in SDL_evdev (supports Raspberry Pi)
tvc

I've spent the last few days implementing touchscreen support in core/linux/SDL_evdev.c. It's fairly rudimentary at the moment, as can be seen from the multiple TODO's and FIXME's littered throughout, but I'm mainly submitting this patch for review. I've tested this patch on my Raspberry Pi 2 with the official touchscreen and it works fantastically, reporting all 10 multitouch points. I'm happy to work on this further, the evdev logic also needs a bit of a cleanup I think (I may have included a few changes). But if it's good enough in its current state to be committed then I'm sure there'd be plenty of people pleased, as currently the only other framework/library that supports touchscreens on the Raspberry Pi is Kivy.

473051f6bb Fixed bug 3159 - SDL_blit_slow with BLENDING does not work
Fritzor

Source Suface is ABGR and Destination Surface is ABGR. We use software blending. In the Switch-Case statement for SDL_COPY_BLEND (Line 126) the alpha-channel is not calculated like in every SDL_blit_auto - function. So if the destination Surface has alpha - channel of zero the resulting surface has zero as well.
Add:  ?dstA = srcA + ((255 - srcA) * dstA) / 255;? to code and everything is okay.

13dd2ccda8 Fixed bug 3161 - SDL_WINDOWEVENT_EXPOSED event possible queue overflow
Marcel Bakker

Observed when resizing or moving a window in Windows 7.

Depending on how you resize/move your window
, you may receive none or a lot of SDL_WINDOWEVENT_EXPOSED events
, at the moment you release the mouse button.

Maybe add this event to an already existing list of overflow candidates ?

614cb35a4d Fixed bug 3165 - define numbers don't match types in Swift
C.W. Betts

Swift is very strict with types, so much that those of different signedness/size must be cast. Most of the defines are imported as 32-bit signed integers, while the corresponding field in a struct is a 32-bit unsigned integer. Appending a "u" would cause the defined types to be imported as 32-bit unsigned integers.

 	SDL_RendererInfo renderer_info;
 	if (SDL_GetRenderDriverInfo(i, &renderer_info) != 0) {

 	}
 	std::cerr << "Renderer " << i << " '" << renderer_info.name << "': flags=0x"

    renderer = SDL_CreateRenderer(window, wanted_renderer, 0);

... on banana pi or raspberry pi I get an error like the following (the actual
context profile value varies, being used uninitialized)

 ERROR: Couldn't create renderer: Unknown OpenGL context profile 900

With this patch I get the following, which should help more pointing to a real problem:

7b0ccd32e5 Fixed bug 3405 - Wrong default icon size on windows systems
Evgeny Vrublevsky

Original code in the video/windows/SDL_windowsevents.c registers obsolete WNDCLASS (not WNDCLASSEX). As the result only one icon size is used as the small and normal icons. Also original code doesn't specify required size of an icon. As the result when 256x256 icon is available, the program uses it as a default icon, and it looks ugly.

We have to use WNDCLASSEX and load icons with proper sizes which we can get using GetSystemMetrics.

Better idea. We could use the first icon from resources, like the Explorer does. Patch is included. It also correctly loads large and small icons, so it will look nice everywhere.

86b4319d21 Fixed bug 3422 - OpenGL ES 1.1 renderer: SDL_UpdateTexture breaks later function calls (missing glDisable)
ny00

Using the OpenGL ES 1.1 renderer, after updating a texture with SDL_UpdateTexture (or SDL_UnlockTexture), a following call to SDL_RenderFillRect draws a rectangle with the wrong color (which appears to be the same as the texture's top-left pixel).

Comparing SDL_render_gles.c:GLES_UpdateTexture to SDL_render_gl.c:GL_UpdateTexture, a missing call to glDisable appears to be the cause. After adding it back, the bug is resolved.
