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.
330f2911	2017-01-22T22:15:24	WinRT: Fixed typo in README.
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.
5e78bc64	2017-01-21T22:00:40	Fixed copyright symbol in testgles2 program.
a395a907	2017-01-20T16:40:11	Fixed mapping the PG-9021 which, on Linux, emits a button partway through the trigger press along with axis motion all along the pull
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.
06d1d945	2017-01-14T21:35:49	Fixed doxygen warning and linking of function names.
a812b4eb	2017-01-14T21:35:18	Changed Bugzilla link in README.md to HTTPS like in BUGS.txt.
2b481015	2017-01-14T21:34:45	Fixed warnings about missing initializers in testoverlay2 program.
341d1ff9	2017-01-13T11:37:12	Fixed comment
01f66613	2017-01-12T10:58:35	fixed SENSOR_LANDSCAPE and SENSOR_PORTRAIT mode false nativeResume bug
acd76826	2017-01-10T23:23:32	We don't actually build with the Xt library
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.
97f19cc3	2017-01-09T15:56:11	testresample: write correct length to the .wav header.
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.
53588ff6	2017-01-08T14:16:19	README-linux: added notes about libsamplerate.
25b47ea3	2017-01-08T10:52:02	Fixed attempting to dynamically load libsamplerate when shared object loading is disabled. Thanks to Ozkan Sezer for pointing this out
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.)
70c8bd24	2017-01-07T22:24:45	Fixed a bunch of compiler warnings in the test code.
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.
5fcd454a	2017-01-06T20:00:17	emscripten-buildbot.sh: let user override default SDKDIR.
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"...
345c5989	2017-01-06T03:15:27	haiku: Patched to compile.
3443dc19	2017-01-05T23:53:46	Don't do any audio conversion if none is necessary
41be9756	2017-01-05T23:26:13	Fixed bug 3546 - SDL_EVDEV_is_console() uses type of wrong size when calling ioctl Rob When calling ioctl(fd, KDGKBTYPE, &type) in SDL_EVDEV_is_console(), we declare type as an 'int'. This should be a 'char'. The subsequent syscall, and kernel code, only writes the lower byte of the word. See: http://lxr.free-electrons.com/source/drivers/tty/vt/vt_ioctl.c?v=4.4#L399 ucval = KB_101; ret = put_user(ucval, (char __user *)arg); I've observed intermittent behavior related to this, and I can force an error condition by using an int initialized to 0xFFFFFFFF. The resulting ioctl will set type to 0XFFFFFF02, and the conditional return in SDL_EVDEV_is_console() will fail. Recommend changing to char, or masking off unused bits.
b3e8db80	2017-01-06T01:07:34	audio: rename fake_stream to work_buffer. It's more than an alternative for when the OS can't provide a DMA buffer, now.
992124d4	2017-01-06T01:02:58	audio: Fixed SDL_AudioStreamGet() function parameters. There was a draft of this where it did audio conversion into the final buffer, if there was enough room available past what you asked for, but that interface got removed, so the parameters didn't make sense (and we were using the wrong one in any case, too!).
99fc1ef9	2017-01-06T00:56:29	naclaudio: Untested attempt to migrate to SDL_AudioStream.
115d0ce7	2017-01-06T00:50:01	haikuaudio: Untested attempt to get this working with SDL_AudioStream.
1a90c72d	2017-01-06T00:49:35	emscriptenaudio: don't get stuck in infinite loop if SDL_AudioStreamPut fails.
f07a1a5a	2017-01-05T21:31:02	emscriptenaudio: Reworked to use SDL_AudioStream.
3761b5f6	2017-01-05T20:11:19	Fixed a few compiler warnings.
4aa9e369	2017-01-05T19:45:57	Patched to compile on some compilers.
52130bde	2017-01-05T19:30:45	diskaudio: Use SDL_Log, not fprintf.
30178a9b	2017-01-05T19:29:38	audio: Added SDL_AudioStream. Non-power-of-two resampling now works!
f12ab8f2	2017-01-05T19:12:20	audio: More effort to improve and simplify audio resamplers.
d024c724	2017-01-05T08:16:39	Fixed signedness issue when blitting on a big endian platform, as reported by capehill For example, if sR is 0 and dR is 255, we will get -255*sA casted to an unsigned value. Basically results are quite large numbers instead of the expected 0-255 range.
e6e6613c	2017-01-05T02:53:29	Fixed build warning on Haiku
4938c505	2017-01-04T10:28:07	Added SDL_JoystickGetAxisInitialState() to get a joystick axis' initial value. This is useful for controller mapping programs to determine an axis' zero state
99e10ef5	2017-01-04T07:06:48	Assume D-pad or thumbstick style axes are centered at 0
9d042052	2017-01-04T09:33:47	x11: deal with xrandr display size in millimeters being zero. Xquartz on macOS reports a zero size, which leads to a division by zero here.
26f84d74	2017-01-04T06:21:17	Added mappings for several GameCube and SNES controllers
d2a01b6e	2017-01-04T06:19:56	Added the NEXT SNES Controller to the list of zero-centered joysticks
c7780497	2017-01-04T05:56:47	Increased joystick jitter tolerance for PS3 controllers
1ddff75c	2017-01-04T05:09:02	Some controllers have trouble getting out to 20000
082132a7	2017-01-03T23:39:28	Fixed binding the D-pad on some Super NES style controllers Fixed a case where partial trigger pull could be bound to another button There is a fundamental problem not resolved by this commit: Some controllers have axes (triggers, pedals, etc.) that don't start at zero, but we're guaranteed that if we get a value that it's correct. For these controllers, the current code works, where we take the first value we get and use that as the zero point and generate axis motion starting from that point on. Other controllers have digital axes (D-pad) that assume a zero starting point, and the first value we get is the min or max axis value when the D-pad is moved. For these controllers, the current code thinks that the zero point is the axis value after the D-pad motion and this doesn't work. My hypothesis is that the first class of devices is more common and that we should solve for that, and add an exception to SDL_JoystickAxesCenteredAtZero() as needed for the second class of devices.
d3591800	2017-01-03T00:44:05	Fixed bug 3519 - SDL_GetDisplayMode fails to report mode.format when using Wayland backend Ryan C. Gordon Kristian says you can't do it with Wayland, and that going forward, it'll just handle whatever you throw at it anyhow. https://twitter.com/hoegsberg/status/816148272402165761 So I say we mark it SDL_PIXELFORMAT_RGB888, which is what my X11 display currently reports, and leave it at that.
18d9b23c	2017-01-02T10:30:32	Fixed bug 3539 - SDL2, missing MIR LDFLAGS Gianfranco Hello, this is the failure I got https://launchpadlibrarian.net/300679206/buildlog_ubuntu-zesty-amd64.libsdl2_2.0.5+dfsg1-2ubuntu1_BUILDING.txt.gz LTLINK build/libSDL2.la build/.libs/SDL_mirvideo.o: In function `MIR_InitDisplayFromOutput': ././src/video/mir/SDL_mirvideo.c:258: undefined reference to `mir_output_get_current_mode' collect2: error: ld returned 1 exit status
67ed8943	2017-01-01T19:10:36	Fixed bug 3529 - SDL_EGL_UnloadLibrary is not called at all on SDL_Quit kaisyu In case of OpenGLES, the sequences of loading and unloading driver library should be like that: SDL_Init ... SDL_GL_LoadLibrary SDL_EGL_LoadLibrary ... SDL_Quit ... SDL_GL_UnloadLibrary SDL_EGL_UnloadLibrary ... However, according to my test results, the varible '_this->gl_config.driver_loaded' does not allow 'SDL_GL_UnloadLibrary' to call 'SDL_EGL_UnloadLibrary'.

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.

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.

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.

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 3546 - SDL_EVDEV_is_console() uses type of wrong size when calling ioctl Rob When calling ioctl(fd, KDGKBTYPE, &type) in SDL_EVDEV_is_console(), we declare type as an 'int'. This should be a 'char'. The subsequent syscall, and kernel code, only writes the lower byte of the word. See: http://lxr.free-electrons.com/source/drivers/tty/vt/vt_ioctl.c?v=4.4#L399 ucval = KB_101; ret = put_user(ucval, (char __user *)arg); I've observed intermittent behavior related to this, and I can force an error condition by using an int initialized to 0xFFFFFFFF. The resulting ioctl will set type to 0XFFFFFF02, and the conditional return in SDL_EVDEV_is_console() will fail. Recommend changing to char, or masking off unused bits.

Fixed binding the D-pad on some Super NES style controllers Fixed a case where partial trigger pull could be bound to another button There is a fundamental problem not resolved by this commit: Some controllers have axes (triggers, pedals, etc.) that don't start at zero, but we're guaranteed that if we get a value that it's correct. For these controllers, the current code works, where we take the first value we get and use that as the zero point and generate axis motion starting from that point on. Other controllers have digital axes (D-pad) that assume a zero starting point, and the first value we get is the min or max axis value when the D-pad is moved. For these controllers, the current code thinks that the zero point is the axis value after the D-pad motion and this doesn't work. My hypothesis is that the first class of devices is more common and that we should solve for that, and add an exception to SDL_JoystickAxesCenteredAtZero() as needed for the second class of devices.
