6046fd4c	2017-02-14T03:03:27	wasapi: Initial WASAPI support, for Windows Vista and later. This should remain binary compatible with Windows XP, as we dynamically load anything we need and fall back to DirectSound/WinMM/XAudio2 if not available.
c93bca48	2017-02-14T02:49:08	stdlib: Fixed crash on SDL_snprintf("%s", NULL). Like other C runtimes, it should probably produce the string "(null)". This bug probably only affected Windows, as most platforms use their standard C runtime's snprintf().
d1eb2d19	2017-02-13T17:05:14	thread: Don't use SetThreadDescription on WinRT right now. Can't LoadLibrary for it, but not sure if it's actually available there yet.
70c0400b	2017-02-13T17:00:46	windows: Try to unify all the GUID comparison code into a core helper function. There are likely several more I missed.
e5fc93ba	2017-02-13T16:59:02	audio: Don't wrap bootstrap declarations in preprocessor macros. They are harmless and ignored if we don't actually link against them. The preprocessor checks elsewhere if they're actually used.
ad9c702f	2017-02-13T16:56:41	audio: SDL_AudioStream's *_sample_frame_size should be in bytes, not bits. Fixes failures where SDL_AudioStreamGet() incorrectly thinks it got a partial sample frame request.
175f1e8f	2017-02-13T16:55:00	audio: Added a ThreadDeinit() method to match ThreadInit. Not used by any targets at the moment, but will be shortly!
886736a2	2017-02-11T16:38:16	Fixed bug 3584 - Small stack size for audio callback thread Walter van Niftrik We have found that since SDL 2.0.5 the audio callback thread is created with a very small stack size. In our application this is leading to stack overflows. We believe there is a bug at http://hg.libsdl.org/SDL/file/391fd532f79e/src/audio/SDL_audio.c#l1132, where the is_internal_thread flag appears to be inverted.
cf31ea14	2017-02-11T11:14:48	Fixed bug 3583 - X11 touch device can be permanently lost Volumetric In X11 the SDL error "Unknown touch device" can occur after which the application stops recognizing touch events. For a kiosk-type application this results in a hang as far as the user is concerned. This is reproducible on HP Z220/Z230/Z240 workstations by swapping USB cables for a while and it also occurs with no physical changes, probably due to USB device power management. A workaround is to make SDL re-enumerate the touch devices like it does at startup. A patch is attached.
06ccb71b	2017-02-10T11:21:15	Make sure the memory barrier functions are always available, and now they are implemented on Android __ARM_ARCH_5TE__
9171f71d	2017-02-10T09:41:16	Fixed warning in Android build
107c19da	2017-02-09T06:01:14	Log the error returned by XAudio2Create()
8eee82cd	2017-02-03T23:30:43	Windows: Fixed warning about unused variable. Found by buildbot.
33ff5bd1	2017-02-03T23:30:29	Fixed typo in log message.
710ae62a	2017-02-02T17:33:40	Remember XInput controllers that we've already seen, so when the raw device list changes we don't assign the old device to the new XInput userid. This isn't perfect, but at least we won't report the same device twice.
8f78f5bb	2017-02-02T16:56:02	Fixed build on Apple TV
da30992d	2017-02-02T00:41:58	Fixed bug 3577 - Can't set minimal size (message box appears instead) if maximal size wasn't declared (i.e. unlimited)
be28d7c8	2017-01-31T12:30:55	Added support for the Saitek Pro Flight X-56 Rhino
6717a3d3	2017-01-31T12:23:29	Added support for the HOTAS Warthog throttle
a156b0d9	2017-01-31T10:20:09	Added the HOTAS Warthog as a flight stick
800a72eb	2017-01-31T10:19:56	Switch stderr output to SDL_Log() so it shows up on Windows and mobile devices
52e9c42d	2017-01-28T14:35:35	Fixed Windows build
869b7fe3	2017-01-28T11:17:10	Fixed bug 3550 - No mouse move messages send while over the titlebar and windows edges Matthew Its possible to set SDL_CaptureMouse() so you continue receiving mouse input while the mouse is outside your window. This works however There is then a gap where no messages send, which is when the mouse is hovering the title bar and the window edges.
c3eea703	2017-01-28T10:54:12	Use a stronger X font definition for X11_MessageBox on UTF-8 X11 seemed to be confused by the broad definition, so WEIGHT_NAME, SLANT and SETWIDTH_NAME were defined, thus fixing the font lookup on some systems (tested on Mageia 6 with X11 1.19.1). Fixes bug 3571.
13433c4a	2017-01-27T21:23:27	Fixed bug 3569 - GL_UpdateViewport leaves PROJECTION matrix selected Tom Seddon GL_ActivateRenderer may call GL_UpdateViewport, which leaves the GL_PROJECTION matrix selected. But after GL_ResetState, the GL_MODELVIEW matrix is selected, suggesting that's the intended default state. It seems at least like these should be consistent. Presumably GL_UpdateViewport should be doing a glMatrixMode(GL_MODELVIEW) before it finishes.
0090a338	2017-01-27T21:16:38	Return an error if trying to set a window minimum size larger than the maximum size, or vice versa
d0247368	2017-01-27T18:06:50	Sorted controller entries
8fa9b57f	2017-01-27T20:50:30	windows: first shot at naming threads with SetThreadDescription(). This is a bleeding edge API, added to Windows 10 Anniversary Edition (build 1607, specifically). https://msdn.microsoft.com/en-us/library/windows/desktop/mt774976(v=vs.85).aspx Nothing supports this yet, including WinDbg, Visual Studio, minidumps, etc, so we still need to also use the RaiseException hack. But presumably tools will use this API as a more robust and universal way to get thread names sooner or later, so we'll start broadcasting to it now.
95ab9dc7	2017-01-27T06:05:50	Added Thrustmaster Wheel FFB entry to the list of wheels
3c90a52a	2017-01-27T05:59:58	Added an API to get the type of a connected joystick
aa90b730	2017-01-26T21:25:05	Add a mapping for Xbox Wireless Controllers running old firmware Also updates the naming of these Xbox Wireless Controllers connected via USB (and thus the third-party Xbox Controller Driver) to match. The Xbox Wireless Controller entries are now listed, in order, via USB, bia Bluetooh (with older firmware) and via Bluetooth (with firmware 3.1.1221.0).
ae5e9a31	2017-01-25T22:24:54	Add gamecontrollerdb mapping for Xbox One S on Mac This is valid for firmware version 3.1.1221.0; earlier versions of the firmware need a different mapping (and have different GUIDs).
ca89d9b5	2017-01-25T22:22:05	Darwin: fix detection of Xbox One S controller Firmware revision 3.1.1221.0 changes the mapping of the Xbox One S controller in Bluetooth mode. Aside from changing the layout of other buttons, this revision also changes the triggers to act as Accelerator and Brake axes from the simulation controls page. The Darwin sysjoystick code didn't previously map anything at these axes, making it impossible to detect input on these two buttons.
ede5c734	2017-01-24T19:38:01	Generalized the audio resampling hint for other resampling methods in the future
47e2f4e9	2017-01-24T20:30:48	audio: libsamplerate can't resample in-place; make space for a copy if needed.
c7f9dcb6	2017-01-24T15:52:22	audio: Offer a hint for libsamplerate quality/speed tradeoff. This defaults to the internal SDL resampler, since that's the likely default without a system-wide install of libsamplerate, but those that need more can tweak this.
1da3a337	2017-01-24T10:09:29	audio: Fix static analysis concerns about a dead assignment.
8f627c1c	2017-01-24T00:51:33	audio: Make sure SDL_AudioStream's work buffer is 16-byte aligned, for SIMD. Note the giantic FIXME, though!
17dcee20	2017-01-24T00:17:40	audio: Streams now resample in-place. Removed second allocated buffer.
b5eeab77	2017-01-24T00:08:24	audio: allow stereo Sint16 resampling fast path in SDL_AudioStream. This currently favors libsamplerate over the fast path (quality over speed), but I'm not sure that's the correct approach, as there may be surprising changes in performance metrics depending on what packages are available on a user's system. That being said, currently, the only thing with access to SDL_AudioStream is an SDL audio device's thread, and it might be mostly idle otherwise, so maybe this is generally good.
a80cb672	2017-01-24T00:03:36	audio: Fixed off-by-one error in upsampling.
dad07f96	2017-01-23T16:45:50	audio: Resampler now special-cases stereo and mono processing. Turns out that iterating from 0 to channels-1 was a serious performance hit! These cases now tend to match or beat the original audio resampler's speed!
8ce6ddf1	2017-01-23T16:42:47	audio: Fixed incorrect pointer in SDL_ResampleCVT_si16_c2(). Forgot to update this when we changed this to process in-place. Whoops!
ecdc6c12	2017-01-23T12:14:28	audio: Fixed copy/paste bug in float32->sint16/SSE2 scalar leftover code.
4b8f3546	2017-01-23T12:06:10	audio: Fix same bug as last commit, but for _mm_bslli_si128 vs _mm_slli_si128.
fab45018	2017-01-23T12:02:02	audio: use _mm_srli_si128 instead of _mm_bsrli_si128. They're the same thing (one is generally a #define of the other), but some toolchains don't offer the 'b' version.
3594bf8e	2017-01-23T01:05:44	audio: Wired up new SSE code to build system.
64056e81	2017-01-23T00:57:19	audio: Added SSE3 implementation of SDL_ConvertStereoToMono().
8855daac	2017-01-22T23:48:15	audio: Make the simple resampler operate in-place. This allows us to avoid an extra copy, allocate less memory and reduce cache pressure. On the downside: we have to do a lot of tapdancing to resample the buffer in reverse when the output is growing.
202ab30c	2017-01-22T20:27:48	audio: Special case for resampling stereo AUDIO_S16SYS audio data. This is a fairly common case, so we avoid the conversion to/from float here.
a7f86f2f	2017-01-22T20:18:59	audio: don't cast to double in SDL_ConvertStereoToMono(). It's expensive and (hopefully) unnecessary. If this becomes an overflow problem, we could multiply both values by 0.5f before adding them, but let's see if we can get by without the extra multiplication first.
4f981df3	2017-01-22T22:15:36	Haiku: Fixed memory leak if creating framebuffer failed.
63e83a31	2017-01-21T22:01:17	Haiku: Removed unused variable. Found by Cppcheck.
800a9e84	2017-01-21T22:00:56	Fixed compiler warning about returning a value in a void function.
83454c82	2017-01-20T16:26:24	audio: removed conditional from simple resampler's inner loop. We never seem to overflow the source buffer now; this might have been a leftover from a bug that was covered by Vitaly's fixes? Removing this conditional makes the resampler 10-20% faster. Left an assert in there for debug builds, in case this still happens.
8fa0b088	2017-01-20T08:13:23	Added support for the 8Bitdo Zero GamePad
9b99265a	2017-01-19T20:19:37	Fixed mingw64 32-bit build, which does have the correct structure definitions
f3540242	2017-01-18T12:19:57	Removed unused variable
b0c5ceef	2017-01-18T12:18:50	Fixed bug 3533 - Enumeration joystick devices omitted during directinput enumeration white.magic The logic which decides if a device enumerated via the direct input system in the function EnumJoysticksCallback in SDL_dinputjoystick.c is processed is discarding valid joystick devices due to the assumption that devices of the type DI8DEVTYPE_SUPPLEMENTAL are not valid devices. This change was added with 2.0.4 with this commit http://hg.libsdl.org/SDL/rev/1b9d40126645 that is linked to this bug report https://bugzilla.libsdl.org/show_bug.cgi?id=2460 which indicates that in that case devices of the type DI8DEVTYPE_SUPPLEMENTAL were not desirable as they caused a singular device to emit multiple "device added" events. Since then there appear to have been a few fixes to handle devices that fall into various other classes in the following two commits: http://hg.libsdl.org/SDL/rev/10ffb4787d7a and http://hg.libsdl.org/SDL/rev/6a2bbac05728 Two devices I have reports of failing to be listed when the DI8DEVTYPE_SUPPLEMENTAL type is excluded are ECS Gametric Throttle and Thrustmaster MFD Cougar. Sam Lantinga I verified that the OUYA controller shows up as a single device with this change, so I've reverted the change to ignore supplemental devices, leaving framework in place to easily add devices that we want to ignore.
dd007e3f	2017-01-18T11:58:16	Fixed bug 3561 - Re-acquire device before playing effects if needed. Mathieu Laurendeau Check the result of IDirectInputEffect_SetParameters and re-acquire the device to solve concurrency issues.
5cb1ca55	2017-01-18T11:57:27	Fixed building with mingw32
3e1679c8	2017-01-18T02:11:56	audio: Several fixes to "simple" resampler (thanks, Vitaly!). Fixes Bugzilla #3551.
95defd66	2017-01-17T21:18:31	Use icon width * sizeof(Uint32) instead of icon pitch when copying to icon resource data
57182930	2017-01-16T00:58:28	audio: Implemented SIMD support for audio data type converters. This currently adds an SSE2 implementation (but it's #ifdef'd out for now, until it's hooked up to the configure script and such).
1e66d457	2017-01-15T05:01:59	audio: Some fixes to the audio data type converter code. Removed some needless things ("len / sizeof (Uint8)"), and made sure the int32 -> float code uses doubles to avoid working with large integer values in a 32-bit float.
1e482095	2017-01-14T21:36:06	Fixed comments.
341d1ff9	2017-01-13T11:37:12	Fixed comment
a52d48c5	2017-01-10T08:54:33	Fixed bugs 2570, 3145, improved OpenGL ES context support on Windows and X11 Mark Callow The attached patch does the following for the X11 and Windows platforms, the only ones where SDL attempts to use context_create_es_profile: - Adds SDL_HINT_OPENGL_ES_DRIVER by which the application can say to use the OpenGL ES driver & EGL rather than the Open GL driver. (For bug #2570) - Adds code to {WIN,X11}_GL_InitExtensions to determine the maximum OpenGL ES version supported by the OpenGL driver (for bug #3145) - Modifies the test that determines whether to use the OpenGL driver or the real OpenGL ES driver to take into account the hint, the requested and supported ES version and whether ES 1.X is being requested. (For bug #2570 & bug #3145) - Enables the testgles2 test for __WINDOWS__ and __LINUX__ and adds the test to the VisualC projects. With the fix in place I have run testdraw2, testgl and testgles2 without any issues and have run my own apps that use OpenGL, OpenGL ES 3 and OpenGL ES 1.1.
bf11cd50	2017-01-09T20:37:52	Fixed bug 3552 - Building SDL in release mode fails under VS 2017 RC Lukasz Biel Tried to compile SDL2 using newest version of VS. Got: SDL_audiocvt.obj : error LNK2019: unresolved external symbol memcpy referenced in function SDL_ResampleCVT 1>E:\Users\dotPo\Lib\SDL\VisualC\x64\Release\SDL2.dll : fatal error LNK1120: 1 unresolved externals whole compilation process: http://pastebin.com/eWDAvBce Steps to reproduce: clone http://hg.libsdl.org/SDL using tortoise hg, open SDL\VisualC\SDL.sln, when promted if should retarget solution click ok, select release x64 build type, Build/Build Solution attempt 2, using Visual Studio cmake support: open folder SDL\ select release x64 build type, run CMake\Build CMakeLists.txt build fails When switched to debug build type, buils succeeds in both cases. VS 2017 is still beta.
23020f92	2017-01-09T16:31:57	audio: Don't ever use libsamplerate in the SDL_AudioCVT codepath. It causes audio pops if you're converting in chunks (and needs to allocate/initialize/free on each convert). We'll either adjust this interface when we break ABI for 2.1 to make this usable, or publish the SDL_AudioStream API for those that want a streaming solution. In the meantime, the "simple" resampler produces "good enough" audio without pops and doesn't have to be initialized, so that'll do for now on the SDL_AudioCVT interface.
ad7c26ff	2017-01-09T11:58:01	We only need the first few keymaps corresponding to the following constants: K_NORMTAB, K_SHIFTTAB, K_ALTTAB, K_ALTSHIFTTAB In the normal case we'll load all the keymaps from the kernel, but this reduces the size of the SDL library for the fallback case when we can't get to the tty.
6d6edcb8	2017-01-09T11:30:29	Fixed spacing
4e9c9fce	2017-01-09T10:10:33	Fixed bug 3100 - SetSwapInterval should now be enabled for ANGLE/EGL Mark Logan 2015-08-24 15:57:50 UTC In SDL_windowsopengles.c, WIN_GLES_SetSwapInterval is as follows: WIN_GLES_SetSwapInterval(_THIS, int interval) { /* FIXME: This should call SDL_EGL_SetSwapInterval, but ANGLE has a bug that prevents this * from working if we do (the window contents freeze and don't swap properly). So, we ignore * the request for now. */ SDL_Log("WARNING: Ignoring SDL_GL_SetSwapInterval call due to ANGLE bug"); return 0; } With a recent version of ANGLE (early July) calling SDL_EGL_SetSwapInterval with a D3D11 backend appears to work just fine. I am working on testing this with D3D9. -- Alex Szpakowski I found the bug, it was fixed in 2013. https://bugs.chromium.org/p/angleproject/issues/detail?id=481 In my opinion it should be safe to unconditionally use SetSwapInterval now. Anyone who encounters the bug should update their ANGLE to a version less than 3 years old, especially since they'd be using a SDL version that's 3+ years newer than their ANGLE version.
063c9d40	2017-01-09T06:00:58	audio: Replaced older resamplers in SDL_AudioCVT with the new ones.
a41103b1	2017-01-09T05:59:30	audio: Patched to compile if linking directly to libsamplerate.
e0a40fb6	2017-01-09T02:54:42	Implemented full evdev keyboard text support This is based on the Linux kernel driver, and has fallback mapping tables in case we aren't connected to a virtual terminal.
49292705	2017-01-08T20:03:18	Fixed bug 3545 - SDL_EVDEV_do_text_input() may be too eager to find error cases Rob I've ran into an issue where I successfully receive SDL_KEY[UP,DOWN] events but not SDL_TEXTINPUT or SDL_TEXTEDITING. In my case the code in SDL_EVDEV_do_text_input() is returning early (on error) prior to calling SDL_SendKeyboardText(). I'm running on the RaspberryPi 3, without X11. In SDL_EVDEV_do_text_input() there is a condition to check keysyms with a type value below 0xf0, then subtract 0xf0 from type. Without understanding the purpose of this code, I disabled it, recompiled, and I'm getting correct SDL_TEXTINPUT events. I'm going to guess that my hack/fix is going to be problematic in some other environment, but after some initial testing it looks like everything is running fine in my setup.
7b66295e	2017-01-08T19:04:38	Removed console check, let the kernel decide whether muting is appropriate on this terminal. We don't fail the init if we can't mute the terminal (we might be running from ssh, or on a system without virtual terminals, etc.)
c16dd74f	2017-01-08T18:32:20	Check the return value of SDL_EVDEV_Init()
38854e03	2017-01-08T16:18:49	audio: Improvements in channel conversion code.
35166609	2017-01-08T14:28:44	audio: Patched to compile with libsamplerate support (again).
d005dc21	2017-01-08T14:23:15	audio: Patched to compile with libsamplerate support.
19e937fc	2017-01-08T14:18:03	audio: libsamplerate loading now happens once at init time.
98cc9d10	2017-01-08T14:17:09	Fixed coding style on a function signature.
9d9e92cf	2017-01-08T10:41:22	Fixed bug 3304 - Android black screen on resume Richard Russell Resuming from a suspended state results in a black screen. This only happens when using GLES 1.1 (GLES 2 resumes correctly) and when the render target has been changed using SDL_SetRenderTarget. This problem is new in 2.0.4. The attached test case demonstrates the issue. Sylvain Becker has apparently found a fix as follows: "In the opengles leaf function (in 'src/render/opengles/SDL_render_gles.c'), it appears there is a call to 'GLES_ActivateRenderer' in 'GLES_SetRenderTarget', which is not present in opengles2. When commenting out this 'GLES_ActivateRenderer', it seems to resume fine". This appears to fix the testcase perfectly, but I don't know whether it could have any undesirable side-effects.
b8ab4eb9	2017-01-08T10:15:22	SDL_evdev.c: fix building against old kernel headers (K_OFF may not be defined.)
13f2e542	2017-01-07T19:55:29	x11: make the X11 target work on macOS with Xquartz.
e25f4e50	2017-01-07T16:51:48	Really fixed blit issue for capehill
7e505b0d	2017-01-07T16:49:23	Don't fail if we can't open the tty, this can be a legitimate use case.
61a3ba30	2017-01-07T17:09:14	Replaced a few single-line "//" comments.
267c9509	2017-01-07T13:47:34	Added mappings for the 8Bitdo NES30 Pro and iBuffalo SNES Controller Also swapped the Wii U Pro controller button mappings to position instead of label, as emulators expect from XBox controllers.
e9c2dcda	2017-01-07T10:13:04	Fixed bug 3469 - Keypresses leak to the console with 2.0.5 tvc I believe this patch should fix it, instead of looping through all the tty's and seemingly selecting the wrong one and corrupting the console I've just made SDL open /dev/tty which is the console attached to the current process anyway.
df25258a	2017-01-06T20:43:53	Added configure and cmake support for libsamplerate
c5825b69	2017-01-06T21:23:51	audio: Don't call a NULL function pointer when clearing audio streams. (Partially?) fixes Bugzilla #3547.
c1ac4c68	2017-01-06T21:17:33	Better fix for static analysis issue in SDL_DestroyRenderer(). Follow up fix for Bugzilla #3544.
cbe44f7f	2017-01-06T02:16:26	Added support for using libsamplerate to do audio resampling
37f404fb	2017-01-06T00:47:42	Fixed confusion between Ryan's new audio stream and the audio buffer we were calling stream in the callback
3df77ced	2017-01-06T00:40:22	Just roll back the entire portion of the commit from a8253d439914 which caused bug 3544 until we figure out what the right static analysis fix is.
748f4605	2017-01-06T03:38:14	audio: Add an assert to make sure non-streaming audio uses good buffer sizes.
356c2ead	2017-01-06T00:32:06	Fixed bug 3544 - Memory freeing bug in SDL_DestroyRenderer/SDL_DestroyTexture felix Here's a snippet of SDL_DestroyRenderer from hg revision 10746:7540ff5d0e0e: SDL_Texture texture = NULL; SDL_Texture nexttexture = NULL; /* ... */ for (texture = renderer->textures; texture; texture = nexttexture) { nexttexture = texture->next; SDL_DestroyTexture(texture); } SDL_DestroyTexture removes the texture from the linked list pointed to by the renderer and ends up calling SDL_DestroyTextureInternal, which contains this: if (texture->native) { SDL_DestroyTexture(texture->native); } If it happens that texture->native is an alias of nexttexture two stack frames up, SDL_DestroyRenderer will end up trying to destroy an already freed texture. I've had this very situation happen in dosemu2. Bug introduced in revision 10650:a8253d439914, which has a somewhat ironic description of "Fixed all known static analysis bugs"...

Fixed bug 3584 - Small stack size for audio callback thread Walter van Niftrik We have found that since SDL 2.0.5 the audio callback thread is created with a very small stack size. In our application this is leading to stack overflows. We believe there is a bug at http://hg.libsdl.org/SDL/file/391fd532f79e/src/audio/SDL_audio.c#l1132, where the is_internal_thread flag appears to be inverted.

Fixed bug 3583 - X11 touch device can be permanently lost Volumetric In X11 the SDL error "Unknown touch device" can occur after which the application stops recognizing touch events. For a kiosk-type application this results in a hang as far as the user is concerned. This is reproducible on HP Z220/Z230/Z240 workstations by swapping USB cables for a while and it also occurs with no physical changes, probably due to USB device power management. A workaround is to make SDL re-enumerate the touch devices like it does at startup. A patch is attached.

That being said, currently, the only thing with access to SDL_AudioStream is an SDL audio device's thread, and it might be mostly idle otherwise, so maybe this is generally good.

Fixed bug 3533 - Enumeration joystick devices omitted during directinput enumeration white.magic The logic which decides if a device enumerated via the direct input system in the function EnumJoysticksCallback in SDL_dinputjoystick.c is processed is discarding valid joystick devices due to the assumption that devices of the type DI8DEVTYPE_SUPPLEMENTAL are not valid devices. This change was added with 2.0.4 with this commit http://hg.libsdl.org/SDL/rev/1b9d40126645 that is linked to this bug report https://bugzilla.libsdl.org/show_bug.cgi?id=2460 which indicates that in that case devices of the type DI8DEVTYPE_SUPPLEMENTAL were not desirable as they caused a singular device to emit multiple "device added" events. Since then there appear to have been a few fixes to handle devices that fall into various other classes in the following two commits: http://hg.libsdl.org/SDL/rev/10ffb4787d7a and http://hg.libsdl.org/SDL/rev/6a2bbac05728 Two devices I have reports of failing to be listed when the DI8DEVTYPE_SUPPLEMENTAL type is excluded are ECS Gametric Throttle and Thrustmaster MFD Cougar. Sam Lantinga I verified that the OUYA controller shows up as a single device with this change, so I've reverted the change to ignore supplemental devices, leaving framework in place to easily add devices that we want to ignore.

Fixed bugs 2570, 3145, improved OpenGL ES context support on Windows and X11 Mark Callow The attached patch does the following for the X11 and Windows platforms, the only ones where SDL attempts to use context_create_es_profile: - Adds SDL_HINT_OPENGL_ES_DRIVER by which the application can say to use the OpenGL ES driver & EGL rather than the Open GL driver. (For bug #2570) - Adds code to {WIN,X11}_GL_InitExtensions to determine the maximum OpenGL ES version supported by the OpenGL driver (for bug #3145) - Modifies the test that determines whether to use the OpenGL driver or the real OpenGL ES driver to take into account the hint, the requested and supported ES version and whether ES 1.X is being requested. (For bug #2570 & bug #3145) - Enables the testgles2 test for __WINDOWS__ and __LINUX__ and adds the test to the VisualC projects. With the fix in place I have run testdraw2, testgl and testgles2 without any issues and have run my own apps that use OpenGL, OpenGL ES 3 and OpenGL ES 1.1.

audio: Don't ever use libsamplerate in the SDL_AudioCVT codepath. It causes audio pops if you're converting in chunks (and needs to allocate/initialize/free on each convert). We'll either adjust this interface when we break ABI for 2.1 to make this usable, or publish the SDL_AudioStream API for those that want a streaming solution. In the meantime, the "simple" resampler produces "good enough" audio without pops and doesn't have to be initialized, so that'll do for now on the SDL_AudioCVT interface.

Fixed bug 3100 - SetSwapInterval should now be enabled for ANGLE/EGL Mark Logan 2015-08-24 15:57:50 UTC In SDL_windowsopengles.c, WIN_GLES_SetSwapInterval is as follows: WIN_GLES_SetSwapInterval(_THIS, int interval) { /* FIXME: This should call SDL_EGL_SetSwapInterval, but ANGLE has a bug that prevents this * from working if we do (the window contents freeze and don't swap properly). So, we ignore * the request for now. */ SDL_Log("WARNING: Ignoring SDL_GL_SetSwapInterval call due to ANGLE bug"); return 0; } With a recent version of ANGLE (early July) calling SDL_EGL_SetSwapInterval with a D3D11 backend appears to work just fine. I am working on testing this with D3D9. -- Alex Szpakowski I found the bug, it was fixed in 2013. https://bugs.chromium.org/p/angleproject/issues/detail?id=481 In my opinion it should be safe to unconditionally use SetSwapInterval now. Anyone who encounters the bug should update their ANGLE to a version less than 3 years old, especially since they'd be using a SDL version that's 3+ years newer than their ANGLE version.

Fixed bug 3545 - SDL_EVDEV_do_text_input() may be too eager to find error cases Rob I've ran into an issue where I successfully receive SDL_KEY[UP,DOWN] events but not SDL_TEXTINPUT or SDL_TEXTEDITING. In my case the code in SDL_EVDEV_do_text_input() is returning early (on error) prior to calling SDL_SendKeyboardText(). I'm running on the RaspberryPi 3, without X11. In SDL_EVDEV_do_text_input() there is a condition to check keysyms with a type value below 0xf0, then subtract 0xf0 from type. Without understanding the purpose of this code, I disabled it, recompiled, and I'm getting correct SDL_TEXTINPUT events. I'm going to guess that my hack/fix is going to be problematic in some other environment, but after some initial testing it looks like everything is running fine in my setup.

Fixed bug 3304 - Android black screen on resume Richard Russell Resuming from a suspended state results in a black screen. This only happens when using GLES 1.1 (GLES 2 resumes correctly) and when the render target has been changed using SDL_SetRenderTarget. This problem is new in 2.0.4. The attached test case demonstrates the issue. Sylvain Becker has apparently found a fix as follows: "In the opengles leaf function (in 'src/render/opengles/SDL_render_gles.c'), it appears there is a call to 'GLES_ActivateRenderer' in 'GLES_SetRenderTarget', which is not present in opengles2. When commenting out this 'GLES_ActivateRenderer', it seems to resume fine". This appears to fix the testcase perfectly, but I don't know whether it could have any undesirable side-effects.

Fixed bug 3544 - Memory freeing bug in SDL_DestroyRenderer/SDL_DestroyTexture felix Here's a snippet of SDL_DestroyRenderer from hg revision 10746:7540ff5d0e0e: SDL_Texture *texture = NULL; SDL_Texture *nexttexture = NULL; /* ... */ for (texture = renderer->textures; texture; texture = nexttexture) { nexttexture = texture->next; SDL_DestroyTexture(texture); } SDL_DestroyTexture removes the texture from the linked list pointed to by the renderer and ends up calling SDL_DestroyTextureInternal, which contains this: if (texture->native) { SDL_DestroyTexture(texture->native); } If it happens that texture->native is an alias of nexttexture two stack frames up, SDL_DestroyRenderer will end up trying to destroy an already freed texture. I've had this very situation happen in dosemu2. Bug introduced in revision 10650:a8253d439914, which has a somewhat ironic description of "Fixed all known static analysis bugs"...
