2a2c8d42ca Initial shot at a renderer target for Apple's Metal API.
This isn't complete, but is enough to run testsprite2. It's currently
Mac-only; with a little work to figure out how to properly glue in a Metal
layer to a UIView, this will likely work on iOS, too.

This is only wired up to the configure script right now, and disabled by
default. CMake and Xcode still need their bits filled in as appropriate.

351d6d4784 audio: Port WASAPI to WinRT, remove XAudio2 backend.
XAudio2 doesn't have capture support, so WASAPI was to replace it; the holdout
was WinRT, which still needed it as its primary audio target until the WASAPI
code code be made to work.

The support matrix now looks like:

WinXP: directsound by default, winmm as a fallback for buggy drivers.
Vista+: WASAPI (directsound and winmm as fallbacks for debugging).
WinRT: WASAPI

a6a4e27ae8 Updated SDL's YUV support, many thanks to Adrien Descamps
New functions get and set the YUV colorspace conversion mode:
	SDL_SetYUVConversionMode()
	SDL_GetYUVConversionMode()
	SDL_GetYUVConversionModeForResolution()

SDL_ConvertPixels() converts between all supported RGB and YUV formats, with SSE acceleration for converting from planar YUV formats (YV12, NV12, etc) to common RGB/RGBA formats.

Added a new test program, testyuv, to verify correctness and speed of YUV conversion functionality.

e_pluschauskas

I noticed that after updating SDL to 2.0.6 my application now exports SDL_main.

At GitHub SDL mirror (branch 2.0.5) SDL_main prototyped as
extern C_LINKAGE int SDL_main(int argc, char *argv[]);
but at branch 2.0.6 prototype is
extern C_LINKAGE DECLSPEC int SDL_main(int argc, char *argv[]);

also tidies the unreadable whitespace in win32 case.)

16b8c4ea43 Fixed bug 3811 - change HAVE_COPYSIGN to HAVE__COPYSIGN in SDL_config_windows.h
Ozkan Sezer

The patch below changes HAVE_COPYSIGN macro in SDL_config_windows.h to
HAVE__COPYSIGN, so that _copysign() can be used in SDL_stdlib.h which
is available in many more windows-targeting toolchains such as MinGW,
MSVC >= 6, etc, and not just  MSVC >= 2013. SDL_stdlib.c already has a
specific check for HAVE__COPYSIGN, so I believe this is reasonable.
2017-09-10 10:30:25 -07:00
Sam Lantinga
be1caece4a Correction: copysign has been supported by windows several toolchains
for a very long time, including MSVC6, MinGW, LCC-Win32, (no released
watcom versions though, but that's of no concern.)

f465f24d73 Fixed bug 3760 - RWops doesn't check for integer overflow when stdio_fseek only supports 32 bits
Simon Hug

When RWops seeks with fseek or fseeko it uses the types long or off_t which can be 32 bits on some platforms. stdio_seek does not check if the 64-bit integer for the offset fits into a 32-bit integer. Offsets equal or larger than 2 GiB will have implementation-defined behavior and failure states would be very confusing to debug.

The attached patch adds range checking by using the macros from limits.h for long type and some bit shifting for off_t because POSIX couldn't be bothered to specify min and max macros.

It also defines HAVE_FSEEKI64 in SDL_config_windows.h so that the Windows function gets picked up automatically with the default config.

And there's an additional error message for when ftell fails.

28bf56c12c Fixed bug 3801 - HAVE_LIBSAMPLERATE_H depending on HAVE_LIBC in current SDL_config.h.in
Ozkan Sezer

HAVE_LIBSAMPLERATE_H is depending on HAVE_LIBC in current config.h.in:
it shouldn't be.  HAVE_LIBUDEV_H, HAVE_DBUS_DBUS_H, HAVE_IBUS_IBUS_H,
HAVE_FCITX_FRONTEND_H, and HAVE_ALTIVEC_H have the same situation too.
I suggest something like the following, which moves them out of the
HAVE_LIBC confinement and also moves the windows dx header stuff along
side them. (Not ideal, but a bit cleaner I think.)

d51dc7378b Fixed bug 3797 - configure check for float.h
Ozkan Sezer

Cmake checks for float.h, but configure does not:  the attached patch

HAVE_FLOAT_H macro to SDL_config.h.cmake and SDL_config.h.in.

In SDL_config_macosx.h and SDL_config_windows.h, defined HAVE_FLOAT_H
as 1, where I know that it's true.

d28cb702e4 Fixed bug 3781 - unbalanced #pragma pack(pop) in close_code.h
Ozkan Sezer

Revision 288 (http://hg.libsdl.org/SDL/rev/2f5a6062db86) excluded the
Watcom compiler from forcing 4 byte structure packing in begin_code.h.
However, it missed updating close_code.h, which now has an unbalanced
#pragma pack(pop) if the compiler is Watcom.  The issue seems to have
crawled into SDL2, too.

003d491f86 Fixed bug 3724 - Allow Angle Static Link
Carlos

We would like to add a switch (define) that allows us to compile Angle statically with SDL. That is, getting rid of the OpenGL DLL. Usually you need OpenGL to be loaded dynamically as DLL because implementation is provided by the system but no need with Angle.

Only 2 files need modification and it shouldn't affect current behaivor:
include/SDL_egl.h and src/video/SDL_egl.c, as in here

https://github.com/native-toolkit/sdl/pull/10/files

The flag name could be SDL_VIDEO_STATIC_ANGLE (instead of NATIVE_TOOLKIT_STATIC_ANGLE) as discussed here https://github.com/native-toolkit/sdl/pull/10

We have tested this with both Windows and UWP, using NME engine (https://github.com/haxenme/nme).

fb835f9e3b Fixed bug 2330 - Debian bug report: SDL2 X11 driver buffer overflow with large X11 file descriptor
manuel.montezelo

Original bug report (note that it was against 2.0.0, it might have been fixed in between):  http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=733015

--------------------------------------------------------
Package: libsdl2-2.0-0
Version: 2.0.0+dfsg1-3
Severity: normal
Tags: patch

I have occasional crashes here caused by the X11 backend of SDL2. It seems to
be caused by the X11_Pending function trying to add a high number (> 1024)
file descriptor to a fd_set before doing a select on it to avoid busy waiting
on X11 events. This causes a buffer overflow because the file descriptor is
larger (or equal) than the limit FD_SETSIZE.

Attached is a possible workaround patch.

Please also keep in mind that fd_set are also used in following files which
may have similar problems.

src/audio/bsd/SDL_bsdaudio.c
src/audio/paudio/SDL_paudio.c
src/audio/qsa/SDL_qsa_audio.c
src/audio/sun/SDL_sunaudio.c

I personally experienced this problem while hacking on the python bindings
package for SDL2 [1] (while doing make runtest). But it easier to reproduce in
a smaller, synthetic testcase.

c59d9923b3 Implemented more flexible blending modes for accelerated renderers
This fixes bug 2594 - Propose new blend mode, SDL_BLENDMODE_BLEND_DSTA

	blendMode = SDL_ComposeCustomBlendMode(SDL_BLENDFACTOR_SRC_ALPHA,
	                                       SDL_BLENDFACTOR_ONE_MINUS_SRC_ALPHA,
	                                       SDL_BLENDOPERATION_ADD,
	                                       SDL_BLENDFACTOR_ZERO,
	                                       SDL_BLENDFACTOR_ONE,
	                                       SDL_BLENDOPERATION_ADD);

This fixes bug 2828 - Subtractive Blending

	blendMode = SDL_ComposeCustomBlendMode(SDL_BLENDFACTOR_SRC_ALPHA,
	                                       SDL_BLENDFACTOR_ONE,
	                                       SDL_BLENDOPERATION_SUBTRACT,

	                                       SDL_BLENDOPERATION_SUBTRACT);


This goes partway to fixing bug 3684 - Add support for a pre-multiplied alpha blending mode

	blendMode = SDL_ComposeCustomBlendMode(SDL_BLENDFACTOR_ONE,
	                                       SDL_BLENDFACTOR_ONE_MINUS_SRC_ALPHA,
	                                       SDL_BLENDOPERATION_ADD,

Seems to be a missing functionality. I want to set an icon from RC file. I cant pass MAKEINTRESOURCE(X) string to SDL_RegisterApp() cause string returned by MAKEINTRESOURCE string is not actually a string and SDL_strlen will crash. Moreover LoadImage seems to be loading wrong icon size. LoadIcon seems to be fine.

56363ebf61 Fixed bug 3690 - SDL2 KMS/DRM render context support
Manuel

The attached patch adds support for KMS/DRM context graphics.

It builds with no problem on X86_64 GNU/Linux systems, provided the needed libraries are present, and on ARM GNU/Linux systems that have KMS/DRM support and a GLES2 implementation.
Tested on Raspberry Pi: KMS/DRM is what the Raspberry Pi will use as default in the near future, once the propietary DispmanX API by Broadcom is overtaken by open graphics stack, it's possible to boot current Raspbian system in KMS mode by adding "dtoverlay=vc4-kms-v3d" to config.txt on Raspbian's boot partition.
X86 systems use KMS right away in every current GNU/Linux system.

Simple build instructions:

$./autogen.sh
$./configure --enable-video-kmsdrm
$make

e10a98d2ad Fixed bug 3720 - SDL_GL_GetAttribute doesn't check for initialized video driver
Simon Hug

SDL_GL_GetAttribute doesn't check if a video driver has been initialized and will access the SDL_VideoDevice pointer, which is NULL at that point.

I think all of the attributes require an initialized driver, so a simple NULL check should fix it. Patch is attached.

2008d86696 Fixed bug 3703 - Missing media keys support on Amazon Fire TV remote control
Holger Schemel

Summary: This patch adds support for key events for the "rewind" and "fast forward" media keys on the Amazon Fire TV remote control.

How to reproduce the problem: Run Android build of SDL2 application on the Amazon Fire TV (tested with "stick" version) and log key events.

Expected behaviour: Every key pressed on the Fire TV remote control should result in a corresponding key event (pressed/released).

Observed behaviour: Of the bottom row of buttons on the Fire TV remote control, only the "play/pause" (middle) button generates a key event, while the "rewind" (left) and "fast forward" (right) buttons to not generate any event at all.

The attached patch adds support for these two missing buttons/keys.

Note 1: Some missing definitions were added for the already existing key codes SDL_SCANCODE_APP1 and SDL_SCANCODE_APP2 (to keep up the correct order of enumerations / array positions when adding the two new key codes).

Note 2: Definitions in "scancodes_linux.h" and "scancodes_xfree86.h" (to also add support for these keys on other platforms) were added without testing. However, I was unable to find corresponding definitions for these two media keys for Windows and Mac OS X.

Note 3: I have also updated the (broken) link to the USB usage page standard PDF document (comment in "include/SDL_scancode.h").

553b328664 Fixed bug 3668 - Overflow of SDL_AudioCVT.filters with some downmixes
Simon Hug

There's a chance that an audio conversion from many channels to a few can use more than 9 audio filters. SDL_AudioCVT has 10 SDL_AudioFilter pointers of which one has to be the terminating NULL pointer. The SDL code has no checks for this limit. If it overflows there can be stack or heap corruption or a call to 0xa.

Attached patch adds a function that checks for this limit and throws an error if it is reached. Also adds some documentation.

Test parameters that trigger this issue:
AUDIO_U16MSB with 224 channels at 46359 Hz
                 V
AUDIO_S16MSB with 6 channels at 27463 Hz

The fuzzer program I uploaded in bug 3667 has more of them.

3c955d0540 syswm: prevent buffer overflow if SDL and app have different config headers.
This only affects Wayland and DirectFB, as a Unix system generally has X11
support. Other platforms also have different sizes for the C union in
question, but are likely the only target for that platform, etc.

Apps that might run on Wayland or DirectFB will need to be compiled against
new headers from an official 2.0.6 release, or be prepared to force the x11
target, or not use SDL_GetWindowWMInfo().

"In particular, only one VkSurfaceKHR can exist at a time for a given window. Similarly, a native window cannot be used by both a VkSurfaceKHR and EGLSurface simultaneously"

a52d48c5ab 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.

4a089ca1c8 Fixed bug 3486 - Can't get HINSTANCE of my window
realitix

SDL2 allows to create widow and to get information through SDL_SysWMinfo.
But it misses something, with Vulkan, you need the HWND and HINSTANCE of the window for Win32 system.
Sadly, SDL2 provides only HWND but not HINSTANCE.

In some context, it can be difficult to get the HINSTANCE, indeed, I'm using pySDL2 (Python) and I can only access properties that SDL2 gives me.
I have to use a dirty trick like that to get the HINSTANCE:  (https://raw.githubusercontent.com/bglgwyng/pyVulkan/master/examples/win32misc.py)

9a8642bd6a Fixed bug 3478 - Patch Haiku to use dlopen instead of load_add_on
Kai Sterker

SDL2 on Haiku so far uses Haiku-specific APIs for loading dynamic objects as add-ons, instead of using dlopen to load them as libraries. This, for example, leads to SDL_mixer not being able to load its audio backends, when compiled with standard settings.

As discussed at https://www.freelists.org/post/haikuports/SDL2-mixer-ogg-music-not-playing-and-other-stuff,2 , the best way to deal with this would be using dlopen instead of load_add_on. The following patch implements this change by dropping the Haiku-specific bits and using dlopen instead.

012217f069 Fixed bug 3369 - RaspberryPI ability to specify a Dispmanx layer
Albert Casals

On a RaspberryPI, it might become convenient to specify the Dispmanx layer SDL uses.
Currently, it is hardcoded to be 10000 to sit above most applications.

This can be specially useful when integrating other graphical apps and frameworks like OMXplayer, QT5 etc.. in order to have more flexibility on their Z-order.

83cb2b63a3 Fixed bug 2758 - Android issues with NDK r10c and API-21
Sylvain

After a long time, I found out more clearly what was going wrong.

The native libraries should be built with a "APP_PLATFORM" as low as possible.
Ideally, APP_PLATFORM should be equals to the minSdkVersion of the AndroidManifest.xml
So that the application never runs on a lower APP_PLATFORM than it has been built for.

An additional good patch would be to write explicitly in "jni/Application.mk": APP_PLATFORM=android-10

(If no APP_PLATFORM is set, the "targetSdkVersion" of the AndroidManifest.xml is applied as an APP_PLATFORM to the native libraries. And currently, this is bad, because targetSdkVersion is 12, whereas minSdkLevel is 10.
And in fact, there is a warning from ndk: "Android NDK: WARNING: APP_PLATFORM android-12 is larger than android:minSdkVersion 10 in ./AndroidManifest.xml".)


to precise what happened in the initial reported test-case:
Let say the "c" code contains a call to "srand()".

with APP_PLATFORM=android-21, libSDL2.so contains a undef reference to "srand()".
with APP_PLATFORM=android-10, libSDL2.so contains a undef reference to "srand48()".

but srand() is missing on devices with APP_PLATFORM=android-10 (it was in fact replaced by srand48()).
So, if you build for android-21 (where srand() is available), you will really have a call to "srand()" and it will fail on android-10.
That was the issue. The path tried to fix this by in fact always calling srand48().


SDL patches that were applied are beneficial anyway, there are implicitly allowing they backward compatibility of using android-21 on a android-10 platform.
It can be helpful in case you want to target a higher APP_PLATFORM than minSdkVersion to have potentially access to more functions.
Eg you want to have access to GLES3 functions (or other) of "android-21". But, if dlopen() fails (on android-10), you do a fall-back to GLES2.

36e40d30fc Fixed bug 2923 - Add SDL_PIXELFORMAT_RGBA32 for byte-wise 32bit RGBA data
Daniel Gibson

Ok, I followed the simple approach of just making SDL_PIXELFORMAT_RGBA32 an alias of SDL_PIXELFORMAT_RGBA8888/SDL_PIXELFORMAT_ABGR8888, depending on endianess. And I did the same for SDL_PIXELFORMAT_ARGB32, .._BGRA, .._ABGR.

SDL_GetPixelFormatName() will of course return SDL_PIXELFORMAT_RGBA8888 (or SDL_PIXELFORMAT_ABGR8888) instead of SDL_PIXELFORMAT_RGBA32, but as long as that's mentioned in the docs it shouldn't be a problem.

d2676c2985 Fixed bug 2924 - SDL_CreateRGBSurface[From] versions that take SDL_PIXELFORMAT enum
Daniel Gibson

Currently, SDL_CreateRGBSurface() and SDL_CreateRGBSurfaceFrom() take Uint32 masks for RGBA to "describe" the Pixelformat of the surface.
Internally those value are only used to map to one of the SDL_PIXELFORMAT_* enum values that are used for further processing.

I think it would be both handy and more efficient to be able to specify SDL_PIXELFORMAT_* yourself without using SDL_PixelFormatEnumToMasks() to create masks first, so I implemented functions that do that:
SDL_CreateRGBSurfaceWithFormat() and SDL_CreateRGBSurfaceWithFormatFrom() which are like the versions without "WithFormat" but instead of taking 4 Uint32s for R/G/B/A masks, they take one for a SDL_PIXELFORMAT_* enum value.

Together with https://bugzilla.libsdl.org/show_bug.cgi?id=2923 creating a SDL_Surface* from RGBA data (e.g. from stb_image)  is as easy as
  surf = SDL_SDL_CreateRGBSurfaceWithFormat(0, w, h, bppToUse*8, SDL_PIXELFORMAT_RGBA32);

73f2c5413d Fixed bug 2885 - SDL_stdinc.h doesn't need to include iconv.h
Ryan C. Gordon

We still include iconv.h in SDL_stdinc.h, probably because this header might have referenced the native iconv functions and types directly. Since these are hidden behind a stable ABI now and never just a #define for the system iconv, we shouldn't need this header included from a public SDL header anymore, slowing down external apps compiles and pulling tons of stuff into the namespace.

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.

bb24662c79 Fixed bug 3301 - IBus support on Linux with CMake
joe.gsoc16

I recently looked into Unicode support in SDL2 and realized that
SDL_TEXTEDITING doesn't get triggered at all (Japanese IME).
According to others on IRC it works fine on Windows/Mac but not
for me on (arch)Linux.
When compiling SDL with autotools, IBus support is enabled by
default but not so with CMake.
I never used CMake before but got it working and also included
that pkg-config determines flags for dbus (FIXME in CMakeLists).

77305d47c2 Fixed bug 3345 - SDL_RenderClear inconsistency with ClipRect
Simon Hug

The description of the SDL_RenderClear function in the SDL_render.h header says the following:

"This function clears the entire rendering target, ignoring the viewport."

The word "entire" implies that the clipping rectangle set with SDL_RenderSetClipRect also gets ignored. This is left somewhat ambiguous if only the viewport is mentioned. Minor thing, but let's see what the implementations actually do.

The software renderer ignores the clipping rectangle when clearing. It even has a comment on this: /* By definition the clear ignores the clip rect */

Most other render drivers (opengl, opengles, opengles2, direct3d, and psp [I assume. Can't test it.]) use the scissor test for the ClipRect and don't disable it when clearing. Clearing will only happen within the clipping rectangle for these drivers.

An exception is direct3d11 which uses a clear function that ignores the scissor test.

9fff05f8d6 Fixed bug 3352 - Adding alpha mask support to SDL_SaveBMP_RW
Simon Hug

The current SDL_SaveBMP_RW function that saves surfaces to a BMP uses an old bitmap header which doesn't officially support alpha channels. Applications just ignore the byte where the alpha is stored. This can easily be extended by using a newer header version and setting the alpha mask.

The attached patch has these changes:

- Extending the description of the function in the SDL_surface.h header with the supported formats.
- Refining when surfaces get stored to a 32-bit BMP. (Must have bit depth of 8 or higher and must have an alpha mask or colorkey.)
- Fixing a small bug that saves 24-bit BGR surfaces with a colorkey in a 24-bit BMP.
- Adding code that switches to the bitmap header version 4 if the surface has an alpha mask or colorkey. (I chose version 4 because Microsoft didn't lose its documentation behind a file cabinet like they did with version 3.)
- Adding a hint that can disable the use of the version 4 header. This is for people that need the legacy header or like the old behavior better. (I'm not sure about the hint name, though. May need changing if there are any rules to that.)

Kai Sterker
There are already patches available from mingw64 that fix the issue

https://github.com/Alexpux/MINGW-packages/tree/master/mingw-w64-SDL2

With those applied, I could compile SDL2 without problems. But of course, it would be preferable if SDL built cleanly from source.
