Sam Lantinga e943d1ce5a Fixed bug 3945 - Add eglCreatePbufferSurface function
tomwardio

Proposed patch loads eglCreatePbufferSurface in same manner as other 1.1 functors. This allows custom video drivers to create pbuffer surfaces.

Sam Lantinga 8758b7bf15 Fixed bug 3980 - Fix for KMSDRM driver where cursor would not be shown on some gfx hardware because of unsupported cursor size
Manuel Alfayate Corchete

This fixes a problem with KMSDRM on some graphics hardware where only bigger cursor sizes are supported, such as current Intel gfx. (The kernel-side driver is what limits this: had to look for failing IOCTLs...)
That caused SDL_SetCursor() to fail silently, and we were left with a missing cursor without further explanation.
With this patch, different "standard" sizes are tried and a bigger one is used (with an intermediate and clean buffer only used to write the new cursor to the BO where it will live after) if we get, let's say, 16x16 which is pretty common but our hardware does not support that.

Sam Lantinga 5f38b5d705 Fixed bug 3979 - Failed to link with "multiple definition of `scalbln'" error on both MinGW and MinGW-w64 by CMake
Vitaly Novichkov

Once I ran build of my codecs collection on AppVeyor where my CMake script downloads latest SDL2 from HG repo, failed to link because of math functions conflict:

https://ci.appveyor.com/project/Wohlstand/audiocodecs/build/1.0.44
The revision is b9ff5f8b2303

There are both vanilla MinGW and MinGW-w64 are failed to build.

Sam Lantinga 1c0c90323c Fixed bug 3976 - SDL drivers may leak driverdata memory due to ignoring return value of SDL_AddDisplayMode
C Snover

SDL_AddDisplayMode returns an SDL_bool corresponding to whether or not the given display mode was added or not. It will return SDL_FALSE if a matching display mode already exists in the display's list of display modes, which causes ownership of the mode driverdata to remain with the caller. Some video drivers ignore the return value of SDL_AddDisplayMode, so leak the driverdata memory when SDL_AddDisplayMode returns SDL_FALSE.

Sam Lantinga 8fb3885c3c Fixed bug 3964 - YUV to RGB in video/SDL_yuv.c is broken for any output format of type ABGR8888 or BGR888
raist66676

Here is the bug in latest SDL 2.0.8 development repo. It is obvious and simple to fix by correcting typos on six lines of code.

In src/video/SDL_yuv.c on lines 217, 249, 280, 321, 353, and 384 the wrong conversion functions are called for SDL_PIXELFORMAT_ABGR8888 and SDL_PIXELFORMAT_BGR888. Instead of ABGR functions, BGRA functions are called. These are typos.

Sam Lantinga 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.

Changing the background color causes the titlebar to blend against it on

can accomplish this in our window's view's drawRect implementation, too.

Sam Lantinga 10376eb926 Fixed bug 3901 - Fix vsync-ed pageflips on the KMSDRM video driver
Manuel

I noticed that, at least on Intel GPU hardware, passing SDL_RENDERER_PRESENTVSYNC would result on a static console instead of the program graphics.
That was due to the fact that calling drmModePageFlip() only works if we have previously set up CRTC to one of the GBM buffers with a drmModeSetCrtc() call, so now it's done and things work as expected.

The KMSDRM_GLES_SetupCrtc() call is done only one time, only when needed (when egl_swapinterval is not 0: when it's 0, there's no need for it because we flip by calling drmModePageFlip() anyway).
The place where KMSDRM_GLES_SetupCrtc() call is done may look strange, but it's right: it needs EGL completely ready because it needs to call eglSwapBuffers() internally to work (see more comments about it in the code).

Sam Lantinga afefcbfeba Fixed bug 3876 - Resampling of certain sounds adds heavy distortion
Simon Hug

Patch that adds [-1, 1] clamping to the scalar audio type conversions.

This may come from the SDL_Convert_F32_to_X_Scalar functions. They don't clamp the float value to [-1, 1] and when they cast it to the target integer it may be too large or too small for the type and get truncated, causing horrible noise.

The attached patch throws clamping in, but I don't know if that's the preferred way to fix this. For x86 (without SSE) the compiler (I tested MSVC) seems to throw a horrible amount of x87 code in it. It's a bit better with SSE, but probably still quite the performance hit. And SSE2 uses a branchless approach with maxss and minss.

Sam Lantinga 9fd0d6191c Fixed bug 3821 - Allow SDL_CreateWindow and SDL_CreateRenderer with OpenGL ES 3.0 (GLES3) for Angle (Windows)
Carlos

Angle supports GLES3 but when using these functions (SDL_CreateWindow and SDL_CreateRenderer), defaults again to GLES2.0.

A current workaround (hack) to retrieve a GLES3.0 context with Angle is:

1) set

    SDL_GL_SetAttribute(SDL_GL_CONTEXT_MAJOR_VERSION, 3);
    SDL_GL_SetAttribute(SDL_GL_CONTEXT_MINOR_VERSION, 0);

after InitSDL AND after calling SDL_CreateWindow  (before SDL_CreateRenderer)

2) Comment lines 2032-2044 in SDL_render_gles2.c, funtion GLES2_CreateRenderer

    window_flags = SDL_GetWindowFlags(window);
    if (!(window_flags & SDL_WINDOW_OPENGL) ||
        profile_mask != SDL_GL_CONTEXT_PROFILE_ES || major != RENDERER_CONTEXT_MAJOR || minor != RENDERER_CONTEXT_MINOR) {

        changed_window = SDL_TRUE;
        SDL_GL_SetAttribute(SDL_GL_CONTEXT_PROFILE_MASK, SDL_GL_CONTEXT_PROFILE_ES);
        SDL_GL_SetAttribute(SDL_GL_CONTEXT_MAJOR_VERSION, RENDERER_CONTEXT_MAJOR);
        SDL_GL_SetAttribute(SDL_GL_CONTEXT_MINOR_VERSION, RENDERER_CONTEXT_MINOR);

        if (SDL_RecreateWindow(window, window_flags | SDL_WINDOW_OPENGL) < 0) {
            goto error;
        }
    }

This retrives a GLES3 context as confirmed using glGetString(GL_VERSION). This should be fixed by modifying a few if's.

Ryan C. Gordon fa15674134 coreaudio: changed device close procedure to prevent long hangs in some cases.
The audioqueue thread needs to keep running, and processing the CFRunLoop
until the AudioQueue is disposed of, otherwise CoreAudio will hang waiting for
final data to feed the device.

At least, I think this is how it all works. It definitely fixes the bug here!

Since AudioQueueDispose() calls AudioQueueStop() internally, there's no need
for our thread to handle this, either, which is good because the AudioQueue
would be disposed by this point. So now the AudioQueue is disposed first, and
then our thread is joined, and everything works out okay.

Just in case, we mark the device "paused" before setting everything in motion,
so any further callbacks from CoreAudio will write silence and not fire the
app's audio callback again.

Fixes Bugzilla #3868.

Sam Lantinga d2a2b0c139 Fixed bug 3857 - SDL_ConvertPixels misses YUV conversions
Sylvain

There are various YUV-RGB conversion coefficients, according to https://www.fourcc.org/fccyvrgb.php
I choose the first (from Video Demystified, with integer multiplication),
but the current SDL2 Dither functions use in fact the next one, which follows a specifications called CCIR 601.

Here's a patch to use the second ones and with previous warning corrections.
There are less multiplications involved because Chroma coefficient is 1.
Also, doing float multiplication is as efficient with vectorization.
In the end, the YUV decoding is faster: ~165 ms vs my previous 195 ms.

Moreover, if SDL2 is compiled with -march=native, then YUV decoding time drops to ~130ms, while older ones remains around ~220 ms.

Sam Lantinga e9652b1987 Fixed bug 3857 - SDL_ConvertPixels misses YUV conversions
Sylvain

Few issues with YUV on SDL2 when using odd dimensions, and missing conversions from/back to YUV formats.

1) The big part is that SDL_ConvertPixels() does not convert to/from YUV in most cases. This now works with any format and also with odd dimensions,
  by adding two internal functions SDL_ConvertPixels_YUV_to_ARGB8888 and SDL_ConvertPixels_ARGB8888_to_YUV (could it be XRGB888 ?).
  The target format is hard coded to ARGB888 (which is the default in the internal of the software renderer).
  In case of different YUV conversion, it will do an intermediate conversion to a ARGB8888 buffer.

  SDL_ConvertPixels_YUV_to_ARGB8888 is somehow redundant with all the "Color*Dither*Mod*".
  But it allows some completeness of SDL_ConvertPixels to handle all YUV format.
  It also works with odd dimensions.

  Moreover, I did some benchmark(SDL_ConvertPixel vs Color32DitherYV12Mod1X and Color32DitherYUY2Mod1X).
  gcc-6.3 and clang-4.0. gcc performs better than clang. And, with gcc, SDL_ConvertPixels() performs better (20%) than the two C function Color32Dither*().
  For instance, to convert 10 times a 3888x2592 image, it takes ~195 ms with SDL_ConvertPixels and ~235 ms with Color32Dither*().
  Especially because of gcc vectorize feature that optimises all conversion loops (-ftree-loop-vectorize).

  Nb: I put no image pitch for the YUV buffers. because it complexify a little bit the code and the API :
  There would be some ambiguity when setting the pitch exactly to image width:
  would it a be pitch of image width (for luma and chroma). or just contiguous data ? (could set pitch=0 for the later).


2) Small issues with odd dimensions:
  If width "w" is odd, luma plane width is still "w" whereas chroma planes will be "(w + 1)/2". Almost the same for odd h.
  Solution is to strategically substitute "w" by "(w+1)/2" at the good places ...

- In the repository, SDL_ConvertPixels() handles YUV only if yuv source format is exactly the same as YUV destination format.
  It basically does a memcpy of pixels, but it's done incorrectly when width or height is odd (wrong size of chroma planes). This is fixed.

- SDL Renderers don't support odd width/height for YUV textures.
  This is fixed for software, opengl, opengles2. (opengles 1 does not support it and fallback to software rendering).
  This is *not* fixed for D3D and D3D11 ... (and others, psp ?)
  Only *two* Dither function are fixed ... not sure if others are really used.

- This is not possible to create a NV12/NV12 texture with the software renderer, whereas other renderers allow it.
  This is fixed, by using SDL_ConvertPixels underneath.

- It was not possible to SDL_UpdateTexture() of format NV12/NV21 with the software renderer. this is fixed.

Here's also two testcases:
- that do all combination of conversion.
- to test partial UpdateTexture

Sam Lantinga 54685787ca Fixed bug 3847 - Hit Test x coordinate wrong on secondary monitor
Robert Turner

SDL_windowsevents.c contains code to retrieve the x and y coordinate for a requested hit test. It does this as follows:

    POINT winpoint = { (int) LOWORD(lParam), (int) HIWORD(lParam) };

LOWORD(lParam) does not correctly mask off high bits that are set if the point is on a second (or third, etc.) monitor. This effectively offsets the x-coordinate by a large value.

MSDN documentation suggests that LOWORD() and HIWORD() are the wrong macros for the task, instead suggesting we should be doing something like the following:

    POINT winpoint = { GET_X_LPARAM(lParam), GET_Y_LPARAM(lParam) };

Testing this change on my Windows 10 machine with 2 monitors gives the correct results.

Ryan C. Gordon 1a3b95a11e audio: Replaced the resampler. Again.
This time it's using real math from a real whitepaper instead of my previous
amateur, fast-but-low-quality attempt. The new resampler does "bandlimited
interpolation," as described here: https://ccrma.stanford.edu/~jos/resample/

The output appears to sound cleaner, especially at high frequencies, and of
course works with non-power-of-two rate conversions.

There are some obvious optimizations to be done to this still, and there is
other fallout: this doesn't resample a buffer in-place, the 2-channels-Sint16
fast path is gone because this resampler does a _lot_ of floating point math.
There is a nasty hack to make it work with SDL_AudioCVT.

It's possible these issues are solvable, but they aren't solved as of yet.
Still, I hope this effort is slouching in the right direction.

But clicking on the restore button now doesn't restore the window to its original 640x480 size. Instead, the window size is identical to the screen size now.

Sam Lantinga 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.

Sam Lantinga 222d25ad4b Fixed bug 3805 - Why is there no --enable-video-rpi option in configure?
Andreas Falkenhahn

When compiling SDL for the Raspberry Pi, I have to use the --host parameter to enable compilation of the native Raspberry Pi video driver, like so:

    --host=arm-raspberry-linux-gnueabihf

It took me a while to figure out that this was necessary in order to have the native Raspberry Pi video driver compiled in. I think it would be better if there was an option like --enable-video-rpi that could be passed to configure and that would also show up when saying configure --help. Currently, it?s rather difficult to figure out that you have to use the --host parameter with arm-raspberry-linux-gnueabihf in order to get Raspberry Pi video support. It?s also somewhat inconsistent because most other video drivers can in fact be enabled/disabled through specific configure parameters but there is no such parameter for the native Raspberry Pi video driver.

Sam Lantinga c8e3e0c414 Fixed bug 3799 - SDL_CreateWindow fails with SDL_WINDOW_VULKAN (libvulkan.so.1 not found)
Manuel Sabogal

Android NDK defines Vulkan as libvulkan.so, not libvulkan.so.1. This is causing the program to not being able to create a window using SDL_WINDOW_VULKAN.

To fix this issue just change the line http://hg.libsdl.org/SDL/file/bbaec41e93b5/src/video/android/SDL_androidvulkan.c#l53 from "libvulkan.so.1" to "libvulkan.so"

Sam Lantinga 0782f9be51 Fixed bug 3273 - Fix for slow video subsystem initialization when using XRandR.
Mart?n Golini

I'm having a very slow initialization of the video subsystem that locks the window creation for about 500 ms ( tested in at least 4 different systems ). What i found is that X11_InitModes_XRandR is using XRRGetScreenResources, that explicitly ask to poll the hardware for changes. This is not really necessary since if the data is already available you can use XRRGetScreenResourcesCurrent.
I attached a tentative patch that fix this issue. With the patch there's no lock when the subsystem is initialized and the window creation is instant in my applications. The patch only uses XRRGetScreenResourcesCurrent in X11_InitModes_XRandR but it could be potentially used in X11_GetDisplayModes and X11_SetDisplayMode.

Sam Lantinga 67f9348baa Fixed bug 3790 - Memory leak with surfaces blitting on each other
bastien.bouclet

When creating two surfaces and blitting them onto the other, SDL's internal reference counting fails, and one of the surfaces is not freed when calling SDL_FreeSurface.

Example code :

SDL_Surface *s1 = SDL_CreateRGBSurfaceWithFormat(0, 640, 480, 32, SDL_PIXELFORMAT_ARGB8888);
SDL_Surface *s2 = SDL_CreateRGBSurfaceWithFormat(0, 640, 480, 32, SDL_PIXELFORMAT_ARGB8888);

SDL_BlitSurface(s1, NULL, s2, NULL);
SDL_BlitSurface(s2, NULL, s1, NULL);

SDL_FreeSurface(s2);
SDL_FreeSurface(s1);

With this example, s1 is not freed after calling SDL_FreeSurface, its refcount attribute is still positive.

Ryan C. Gordon 167398b363 video: Let video targets optionally decide their default OpenGL configs.
This is necessary because the Raspberry Pi is a strange beast, that believes
it has OpenGL support (through glX?) but generally has GLES2 support.

So when using the raspberry video target, we need to force this to default
to a GLES2 context, or by default SDL_CreateWindow() will fail, deep down
when it tries to load the proper GL library.

Fixes testsprite2 (and basically everything else that wasn't testgles2) when
run on a Raspberry Pi without a X server.

Please note that other targets might also need this filled in, the Raspberry
Pi is just the most prominent and readily-available System-On-A-Chip style
thing on my desk.  :)

Sam Lantinga c26946e9f2 Fixed bug 3792 - [KMS/DRM] Wrong GBM format
Romain Tisserand

Using KMS/DRM driver from WIP SDL2.0.6 on Linux/ARM SoC RockChip RK3328 (ARM Mali 450 MP2 GPU).

The current code is using GBM_BO_FORMAT_XRGB8888 as GBM buffer format specifier.

The Mali driver (it has been confirmed some other vendor implementations too) expects GBM_FORMAT_XRGB8888.

The Mesa implementation is actually handling both values as the same, but it's not implemented like this into every gbm.h vendor header.

https://github.com/ideak/mesa/blob/master/src/gbm/backends/dri/gbm_dri.c

So with stock SDL2 on my card (Mali vendor implementation), it does not work, eglCreateWindowSurface fails, and gbm_is_format_supported fails too (with the BO variant).
It runs fine with GBM_FORMAT_XRGB8888.

Here is a link of the gbm.h from Mali user-space driver :

we can avoid it...but maybe we can't. I hear Vulkan is pretty cool.

Colin Barrett

Using the pre-built x86 devel libs from here:
https://www.libsdl.org/release/SDL2-devel-2.0.5-VC.zip

If I have:

SDL_GL_SetAttribute(SDL_GL_CONTEXT_PROFILE_MASK, SDL_GL_CONTEXT_PROFILE_ES);
SDL_GL_SetAttribute(SDL_GL_CONTEXT_MAJOR_VERSION, 2);
SDL_GL_SetAttribute(SDL_GL_CONTEXT_MINOR_VERSION, 0);
SDL_GL_SetAttribute(SDL_GL_CONTEXT_FLAGS, SDL_GL_CONTEXT_DEBUG_FLAG);

and I'm using ANGLE/(a GL driver that doesn't provide an ES2 context) such that SDL_EGL_CreateContext is called by SDL_GL_CreateContext, I get the error "Could not create EGL context (context attributes are not supported)" and no context is created.

Looking at the code in SDL_EGL_CreateContext - if gl_config.flags is non-zero, it looks like the code in the section guarded with "#ifdef EGL_KHR_create_context" should be executed - but it apparently isn't.

Is it possible this section hasn't been compiled into the pre-built libraries? If I build SDL2.dll myself using the Visual C++ solution (VS2015 Community Update 3) then the call succeeds as I expect

Sam Lantinga 8fc1fb0805 Fixed bug 3719 - Cocoa - Incorrect window size when leaving fullscreen
bastien.bouclet

When exiting a "fullscreen space" on OS X, windows don't go to their defined "windowed mode size", but go back to their previous size.

Steps to reproduce:
1. Create a windowed mode SDL window
2. Toggle it to fullscreen with the SDL_WINDOW_FULLSCREEN_DESKTOP flag
3. While in fullscreen, change the windowed mode size using SDL_SetWindowSize
4. Toggle the window back to windowed mode

Expected result:
- The window has the size specified during step 3.

Actual result:
- The window has the size specified when creating the window in step 1.

Attached is a minimal reproduction test case.
The attached test case works as expected on X11 and Windows.

Ozkan Sezer

Since the Vulkan merge, building against a Mac OS X SDM older than
10.11 fails in SDL_cocoametalview.m because Metal.framework is not
present. There is no conditional compiling in SDL_cocoametalview.m
either, so --disable-video-vulkan doesn't help with anything. (The
configury doesn't check darwin for x86_64 either, but it's another
story.)

is a problem for me.  Will this be fixed?

Ryan C. Gordon b128e8802d audio: A whole bunch of improvements to audio conversion (thanks, Solra!).
"Major changes, roughly in order of appearance:

- Use float math everywhere, instead of promoting to double and casting back
all the time.
- Conserve sound energy when downmixing any channel into two other channels.
- Add a QuadToStereo filter. (The previous technique of reusing StereoToMono
never worked, since it assumed an incorrect channel layout for 4.0.)
- Add a 71to51 filter. This removes just under half of the cases the previous
code would silently break in.
- Add a QuadTo51 filter. More silent breakage fixed.
- Add a 51to71 filter, removing another almost-half of the silently broken
cases.
- Add 8 to the list of values SDL_SupportedChannelCount will accept.
- Change SDL_BuildAudioCVT's channel-related logic to handle every case, and
to actually fail if it fails instead of silently corrupting sound data and/or
crashing down the road."

(Note that SDL doesn't otherwise support 7.1 audio yet, but hopefully it will
soon and the 7.1 converters are an important piece of that.  --ryan.)

This patch will check for the existence of the getDescriptor function added in Jelly Bean, and use it if it's there.  The Android Dashboard says that the majority of Android phones should support this function, and doing it this way will not force us to bump up our API version.

Clayton Craft

#define DEFAULT_OPENGL  "libGL.so.1"

On at least one distro (Alpine Linux), libGL.so is not created (or more accurately the symlink to libGL.so.1 is not created). For consistency, the 'path' variable in SDL_DirectFB_opengl.c should patch the DEFAULT_OPENGL in SDL_x11opengl.c ("libGL.so.1")

David Ludwig

I've created a new set of patches.  I am happy to create more, if it would help.

One version only copies 'size'.

A second version copies both 'size' and 'silence'.  When looking over the documentation for SDL_OpenAudio in SDL_audio.h, it mentioned that both 'size' and 'silence' were things that SDL_OpenAudio would calculate.

Regarding *both* patches, I did notice that SDL 1.2 appears to have always modified desired's size and silence fields.  The SDL wiki, at https://wiki.libsdl.org/SDL_OpenAudio#Remarks , does note:

Sam Lantinga 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).

safe to do anyhow.

Fixes Bugzilla #3674.

"I did more tests.
It appears the bug only happens if there is
another window on the screen that has "always
on top" property. For me it is xawtv - it is
always opened in a screen corner. Closing
xawtv or removing "always on top" property
from it makes the problem to go away.
Plus, it doesn't appear like the buttons are
not delivered at all. It appears that instead
the button presses are delivered on some mouse
positions, but not delivered when you move the
mouse to other part of the window... So this is
really weird and is likely somewhere deep in the
Xorg.
Maybe somehow it happens that the cursor is
actually above the xawtv window, but, because
my app uses grab, it is not visible there, and
in that case the events are not delivered to
my app?
But with my patch the button events are
always delivered flawlessly, it seems.

Hmm, and that indeed seems to explain my problem:
if the mask is set properly and my app uses
grab, then, even if the mouse is above some
other window, the events would still be delivered
to the grabbing app, which is what actually wanted
because my app uses relative mouse mode, so it
doesn't know the pointer can cross some other window
(my app draws the pointer itself).
So my current theory is that my patch only enforces
the mouse grab, which otherwise can be tricked by
some other window preventing the button events
delivery (but motion events are still delivered
via xinput2, which makes it all look very obscure)."

Sam Lantinga a4cfa93670 Fixed bug 2293 - Precise scrolling events
Martijn Courteaux

I implemented precise scrolling events. I have been through all the folders in /src/video/[platform] to implement where possible. This works on OS X, but I can't speak for others. Build farm will figure that out, I guess. I think this patch should introduce precise scrolling on OS X, Wayland, Mir, Windows, Android, Nacl, Windows RT.

The way I provide precise scrolling events is by adding two float fields to the SDL_MouseWheelScrollEvent datastructure, called "preciseX" and "preciseY". The old integer fields "x" and "y" are still present. The idea is that every platform specific code normalises the scroll amounts and forwards them to the SDL_SendMouseWheel function. It is this function that will now accumulate these (using a static variable, as I have seen how it was implemented in the Windows specific code) and once we hit a unit size, set the traditional integer "x" and "y" fields.

I believe this is pretty solid way of doing it, although I'm not the expert here.

There is also a fix in the patch for a typo recently introduced, that might need to be taken away by the time anybody merges this in. There is also a file in Nacl which I have stripped a horrible amount of trailing whitespaces. (Leave that part out if you want).

Sam Lantinga 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/paudio/SDL_paudio.c
src/audio/qsa/SDL_qsa_audio.c

I personally experienced this problem while hacking on the python bindings

a smaller, synthetic testcase.

Gabriel Jacobo

Thanks for the patch. I think it needs a bit of extra work though, looking at the code in SDL_gesture.c , I see that SDL_numGestureTouches only goes up, I think the right fix here involves adding SDL_GestureDelTouch (hooked into SDL_DelTouch) as well as SDL_GestureQuit (as you posted in your patch).

Sam Lantinga 362d549690 Fixed bug 2500 - X11: SDL tries (and fails) to hide foreign windows
Alvin

I'm interested in this bug as well. I have experienced it when trying to embed an SDL_Window into a FLTK application. To do this, I create a FLTK window (window inside a window - think video player) and then use SDL_CreateWindowFrom() on the inner most window's Xlib Window*. After which, I create a renderer.

In my situation I am using the FLTK GUI toolkit.

What I have experienced is that the SDL_CreateRender() will recreate the window in order to properly setup OpenGL capability. As part of this process, the window is hidden and a call is executed that waits indefinitely for an acknowledgement that the window was indeed unmapped. This is where my program hangs.

Please correct me if I am wrong, but should SDL2 not make Xlib calls that effect the Xlib Window in this situation (e.g. When SDL_CreateWindowFrom() is used)? The toolkit being used typically assumes responsibility and, I presume, tracks all Xlib Windows it creates.

On line src/video/SDL_video.c:1372 the comment associated with setting SDL_WINDOW_FOREIGN reads:

  /* Can't destroy and re-create foreign windows, hrm */

Since I do not know the reason for hiding the window in the first place, the attached patch simply does not wait for a response when X11_XWithdrawWindow() and X11_XMapRaised() are issued by X11_HideWindow() and X11_ShowWindow(), respectively. I presume that the GUI toolkit (GTK, FLTK, etc.) has or will consume the acknowledging event as it is managing the Xlib Window (or it thinks it is).

I have tested the patch against hg 5c645d037de2 and I have successfully tested:
* Embedding the SDL_Window inside a FLTK application.
* Calling SDL_SetWindowSize() when FLTK resizes the window (e.g. dragging cursor on the edge of the window).
* Filling the renderer's default target blue and drawing a red fill square at the centre (exciting, I know!)
* Calling SDL_Quit() when the application terminates

I do not receive any Xlib erorr messages (BadWindow, etc.) in any of those situations.

I am compiling with the Sun Studio 12 u2 compiler. There are multiple issues with the build, but this particular issue appears to be that it is illegal to declare a union of a struct of floats and a float. While GCC 4.8.1 does not flag this as an error, Sun Studio is much more standards compliant and strict, halting further compilation with an error.

Sam Lantinga 72ab258812 Fixed bug 2764 - Timer is not rescheduled with the returned interval
afwlehmann

Sorry for re-opening, but it turns out that the current interval is indeed not updated. I've just checked the source code of the 2.0.3 release again:

   163	    if (current->canceled) {
   164	        interval = 0;
   165	    } else {
   166	        interval = current->callback(current->interval, current->param);
   167	    }
   168
   169	    if (interval > 0) {
   170	        /* Reschedule this timer */
   171	        current->interval = interval; // <-- this line is missing
   172	        current->scheduled = tick + interval;
   173	        SDL_AddTimerInternal(data, current);
   174	    } else {

According to the documentation: "The callback function is passed the current timer interval and the user supplied parameter from the SDL_AddTimer() call and returns the next timer interval. If the returned value from the callback is 0, the timer is canceled."

If I understand the text correctly, then the current interval should in fact be updated according to the returned value. Otherwise there would be a discrepancy between the next time for which the timer is actually re-scheduled and the value that's passed to the callback once the timer fires again.

This could be fixed by adding line #171.

As far as I can see, *SDL_BlitFunc() is completely internal to SDL with

to SDL_BlitFunc seem to not have any calling conventions specified. So,
easy solution is simply removing the strict calling convention from the
type.

Sam Lantinga 6ef1a25d18 Fixed bug 3751 - DirectFB linux_input disabled by default
Clayton Craft

linux_input module is disabled by default, despite the comments in source code that it is otherwise:

src/video/directfb/SDL_DirectFB_video.c:
    devdata->use_linux_input = readBoolEnv(DFBENV_USE_LINUX_INPUT, 0);       /* default: on */

src/video/directfb/SDL_DirectFB_video.h:
    #define DFBENV_USE_LINUX_INPUT      "SDL_DIRECTFB_LINUX_INPUT"      /* Default: on  */

When using the directfb driver, the linux_input module is suppressed unless the SDL app is started with "SDL_DIRECTFB_LINUX_INPUT=1" set in the environment. I recall seeing at one point that the directfb folks recommended using linux_input over the other input drivers, but I am having trouble locating this recommendation. In any case, I believe that this should really be defaulted to 'on' since it's vastly superior to the other dfb input drivers!

Sam Lantinga ddeaa6016c Fixed bug 3299 - DirectInput: Incorrect joystick mapping when attaching new joysticks
Jimb Esser

Note: This is using DirectInput, I have to disable XInput as that causes all but the first 4 controllers to be completely ignored by SDL (I can find no way to reconcile XInput devices with DirectInput devices, otherwise I would make a patch that accepts the fifth and later controllers with DirectInput...).  XInput does not seem to have the problem below, only DirectInput.

I plug in 3 identical wireless Xbox 360 controllers, call them J1, J2, J3.  Direct Input shows them as having GUIDs G1, G2, G3.  I unplug J1, then J2 and J3 show up as having GUIDs G1 and G2!  Not so "unique"...  I start my SDL app when just J2 and J3 are plugged in, and open J2 and J3.  Then I plug in a new controller, SDL sees that now G3 exists, assigns that a new SDL joystick instance ID, which I request to be opened, but G3 at this point is J3, which I already had opened!  So I end up with two instances of J3 opened, and none of J1.  "Re-"opening G1 would get the actual handle to the newly attached controller, but there's no current way to know this.  This is clearly a bug or poor design in DirectInput or my wireless receiver drivers, but is a showstopping bug for my 8-20 player games (as soon as any one controller runs out of battery or goes to sleep and gets turned back on, suddenly things are busted requiring a restart (or, at least, a reinitialization of all controllers - the game can't go on)).

The solution I found is to use HID paths instead of GUIDs to uniquely identify joysticks.  GUIDs are still needed to open a controller, however I have added code to re-find the GUIDs for all joysticks whenever a new joystick is attached or removed.  This does now require opening of all joysticks (instead of just enumerating them), though if your app, like mine, is opening all of them anyway so that any can press a button to join, that doesn't change much (although perhaps they joysticks should be kept open in this case, instead of closed and re-opened).  If your app only ever opens one joystick, this will do more work at startup than it did previously.

Sam Lantinga 059d9e4627 Fixed bug 2950 - wrong axes values are set on joystick initialization
Edward Rudd

Device: Logitech Rumble Gamepad F510 in Xinput mode.

Upon opening the joystick the values of the axes are queried via PollAllValues are not actually set on the device all the time.

This can easily be seen in the testjoystick or testgamecontroller test programs,as the testjoystick shows all axes in the center until one 'tickles' the triggers., and the testgamecontroller will show the triggers as 'on' until on 'tickles' the triggers.

Upon further research the culprit is the SDL_HINT_JOYSTICK_ALLOW_BACKGROUND_EVENTS hint. In the default value events are ignored until there is an active window, Thus in cases where the joystick system is initialized and controllers opened before the initial window is created & focuses, the initial values will be incorrect.

Here is my current workaround in the game I'm working on porting..

SDL_SetHint(SDL_HINT_JOYSTICK_ALLOW_BACKGROUND_EVENTS, "1");
SDL_GameController* gamepad = SDL_GameControllerOpen(index);
SDL_SetHint(SDL_HINT_JOYSTICK_ALLOW_BACKGROUND_EVENTS, "0");

Sam Lantinga 05facb3d4e Fixed bug 2979 - SDL_ConvertSurface does not convert color keys consistently
Edmund Horner

When a 16-bit "565 format" surface has a colour key set, it will blit with correct transparency.  If, however, it has its colour key set then is converted to a 32-bit ARGB format surface, the colour key in the converted image will not necessarily be the same pixel value as the transparent pixels.  It may not blit correctly, because the colour key does not match the right pixels.

In my case, with an image using 0xB54A for transparency, the colour key was converted to 180,170,82; but the corresponding pixels (with the same original value) were converted to 180,169,82.  Blitting the converted image did not use transparency where expected.

I have attached a test case.  The bug has been replicated on both x86_64 Linux (SDL 2.0.2), and 32-bit MS C++ 2010 on Windows (SDL 2.0.0).

Sam Lantinga d226594fcc Workaround for bug 3049 - SDL_Init(SDL_INIT_VIDEO) - XDM authorization key matches an existing client!
malferit

Hello, I began a little program with SDL2 on Linux in C, and when I call SDL_Init(SDL_INIT_VIDEO) I get an error and this is printed in the console:

XDM authorization key matches an existing client!

I searched through Internet, and found that some people suggest to run 'xhost +' or to specify this in /etc/X11/xdm/xdm-config:

DisplayManager*authName:        MIT-MAGIC-COOKIE-1

I don't think an end user needs to know that...

But what bothered me is that first I started this little program in Pascal using the Freepascal compiler and it works. In freepascal you only use some thin header bindings in Pascal and then it links with the dynamic SDL library, so I don't understood why it worked with Freepascal and not in C.

I run ldd to the two generated applications:

Application in C:

	linux-gate.so.1 (0xffffe000)
	libSDL2-2.0.so.0 => /usr/lib/libSDL2-2.0.so.0 (0xb76ac000)

	librt.so.1 => /lib/librt.so.1 (0xb7491000)
	/lib/ld-linux.so.2 (0xb77b3000)

Application compiled with Freepascal:

	linux-gate.so.1 (0xffffe000)
	libSDL2-2.0.so.0 => /usr/lib/libSDL2-2.0.so.0 (0xb762a000)
	libX11.so.6 => /usr/lib/libX11.so.6 (0xb74f3000)
	libc.so.6 => /lib/libc.so.6 (0xb7367000)
	libm.so.6 => /lib/libm.so.6 (0xb7325000)
	libdl.so.2 => /lib/libdl.so.2 (0xb731f000)
	libpthread.so.0 => /lib/libpthread.so.0 (0xb7305000)
	librt.so.1 => /lib/librt.so.1 (0xb72fc000)

	libXdmcp.so.6 => /usr/lib/libXdmcp.so.6 (0xb72d3000)
	/lib/ld-linux.so.2 (0xb7755000)

It seems that Freepascal is linking with libX11, libxcb, libXau and libXdmcp .

Linking my C application with libxcb solved the problem (linking with libXau and/or libXdmcp without libxcb didn't work). Linking with X11 links all the other libraries and works as well.

So I fill this bug report mainly to let you know about this. I don't know if it is a problem that can be solved on the libSDL side or not, but at least I hope it will help.

Hi, some tests:

1. Disabled XDM. Login in console and running 'startx'. The program works without having to link with X11.

2. Enabled XDM. Added 'DisplayManager*authName: MIT-MAGIC-COOKIE-1' to /etc/X11/xdm/xdm-config.The program works without having to link with X11.

3. Enabled XDM without 'DisplayManager*authName: MIT-MAGIC-COOKIE-1' in /etc/X11/xdm/xdm-config . I get the authentication error unless I link with X11.

Coriiander

There's a slight mistake in the function "GetWindowStyle" found in file "SDL_windowswindow.c".

When a window is marked to be resizable, the resizable style is being added regardless of whether the window has a border or not. While for some arcane, hidden semantics this can be ok, it's still inconsistent in this case.

Sam Lantinga e3f3a757f3 Fixed bug 3158 - SDL display window scrambled over VNC
Witek Jachimczyk

I'm using SDL to develop a video viewer for MATLAB.  The window is scrambled while using thightVNC with its default mode of RGB656.

SDL does not correctly recognize the pixel mode.


I found a solution for this problem.  The solution involves modifying
SDL/src/video/SDL_pixels.c

Adding the following "if statement" under case 16: of SDL_MasksToPixelFormatEnum resolves the issue:

        if (Rmask == 0x003F &&
            Gmask == 0x07C0 &&
            Bmask == 0xF800 &&
            Amask == 0x0000) {
            return SDL_PIXELFORMAT_RGB565;
        }

I hope that this helps someone.  I took me a while to figure it out.

Sam Lantinga 4a9c6f0a14 Fixed bug 3173 - SDL_GL_GetAttribute overwrites error code from SDL_GL_GetProcAddress
Yann Dirson

When SDL_GL_GetProcAddress returns in error, the cause of the error is overwritten
in GL_GL_GetAttribute, reporting to the user "Failed getting OpenGL glGetString entry point", whereas the original "OpenGL library not loaded" never makes it
to the user.

Pushed a fix to:
f94cb13708


Note that the "OpenGL library not loaded" error looks like no root cause either,
and I'm still puzzled by the code path used: I'm forcing opengles2 renderer on
the x11 video driver on a rpi2, as in https://bugzilla.libsdl.org/3169, and although I now know that I must force the use of the RPI video driver instead
of the x11 one, I suspect even more accurate info can be given to user.

Sam Lantinga 3b837a2659 Fixed bug 3188 - AZERTY keyboard support broken and inconsistent
Daniel Gibson

AZERTY keyboard layouts (which are the default layouts in France and Belgium) don't have the number keys (1, 2, ..., 9, 0) in the first row of keys, but ?, &, ?", ', (, -, ?_, ??), = (with small differences between the France and Belgian variants). Numbers are reached via shift.

On Linux and OSX, SDL seems to use the corresponding ISO 8859-1 codes (231 for ?232 for ?tc) as SDL_Keycode (but no SDK_* constants exists for those values!), while on Windows SDL seems to map those keys to SDLK_1, SDLK_2 etc, like you'd get on QWERTY.
I don't know how other platforms behave.

So we have two problems:
1. At least on Linux and OSX invalid/undefined SDL_Keycodes are returned
2. Different platforms behave differently (Windows vs Linux/OSX)

It's unclear what behavior is desired: Should SDL_* constants for those keys be introduced (and Windows behavior changed accordingly)?
Or should all platforms behave like Windows here and use the existing SDLK_1, ..., SDLK_0 keycodes?

Sam Lantinga 1a5441451c Fixed bug 3309 - SDL_ConvertSurface adds AlphaMod when input surface has ColorKey
Sylvain

Let's you have a SDL_Surface that has ColorKey, but no Alpha Modulation.
When this surface is duplicated with SDL_ConvertSurface function, the result has ColorKey and Alpha Modulation (BLEND, and Opaque 255).

I think SDL_ConvertSurface should strictly keeps the input format.


example
=======

SDL_Surface *input; // ... Set up a surface with ColorKey and no AlphaMod

SDL_Surface *output = SDL_ConvertSurface(input, input->format, input->flags);

// "output" surface has a ColorKey but *also* AlphaMod (BLEND, and Opaque 255).

Sam Lantinga 6f843b902d Fixed bug 3243 - SDL_SetRenderDrawColor() behaves wrong with RGBA=0
Simon Hug

The bug is in the GL_ResetState and GLES_ResetState functions which get called after a new GL context is created. These functions set the cached current color to transparent black, but the GL specification says the initial color is opaque white.

The attached patch changes the values to 0xffffffff to reflect the initial state of the current color. Should the ResetState functions get called anywhere else in the future, this probably has to call the GL functions itself to ensure that the colors match.

Sam Lantinga 195b8bd8ee Fixed bug 3249 - keysym.mod is incorrect when mod keys are pressed for SDL_KEYDOWN events
Adam M.

The keysym.mod field does not reflect the state of the modified keys when processing key down events for the modifier keys themselves. The documentation says that it returns the current key modifiers, but they are not current for key down events involving modifier keys. I interpret "current" to mean "equal to SDL_GetModState() at the instant the event is processed/enqueued".

For example, if you depress the Shift key you get a key down event with .mod == 0. However, .mod should not be 0 because a shift key is down. If you then release the Shift key, you get a key up event with .mod == 0. Neither event reports the modifier key.

If you press Shift and then A, .mod is incorrect (== 0) when Shift is pressed, but is correct later when A is pressed (== KMOD_LSHIFT).

You might say this behavior is deliberate, i.e. keysym.mod is the value /before/ the event, not the current value as documented, but that explanation is incorrect because only key down events behave that way. Key up events correctly give the current value, not the value before the event.

Not only is it inconsistent with itself, I think it makes keyboard processing harder.

The problem is near line 740 in SDL_keyboard.c:

if (SDL_KEYDOWN == type) {
    modstate = keyboard->modstate; // SHOULD THIS BE MOVED DOWN?
    switch (keycode) {
    case SDLK_NUMLOCKCLEAR:
        keyboard->modstate ^= KMOD_NUM;
        break;
    case SDLK_CAPSLOCK:
        keyboard->modstate ^= KMOD_CAPS;
        break;
    default:
        keyboard->modstate |= modifier;
        break;
    }
} else {
    keyboard->modstate &= ~modifier;
    modstate = keyboard->modstate;
}

In the key down path, modstate (and thus keysym.mod) ends up being the modifier state /before/ the event, but in the key up path modstate ends up being the modifier state /after/ the event. Personally I think the "modstate = keyboard->modstate" line should just be moved after the entire if/else statement, so that keysym.mod always reflects the current state.

Sam Lantinga b5ea3c6d07 Fixed bug 3284 - minor correction for SDL_setenv on _WIN32__ platform
Coriiander

Here is a minor correction for a non-breaking mistake in SDL_setenv for __WIN32__ platform. See below for details.

FILE:
"SDL/src/stdlib/SDL_getenv.c"

FUNCTION: (__WIN32__ platform)
int SDL_setenv(const char *name, const char *value, int overwrite)

CODE:
    if (!overwrite) {
        char ch = 0;
        const size_t len = GetEnvironmentVariableA(name, &ch, sizeof (ch));
        if (len > 0) {
            return 0;  /* asked not to overwrite existing value. */
        }
    }


WHAT'S WRONG:
The 3th argument to GetEnvironmentVariable (being DWORD nSize) must be the number of characters, not the number of bytes. SDL currently passes "the size of 1 char", rather "1". While it is non-breaking (1=1 after all), it is incorrect. Furthermore there is no need to specify the 2nd and 3th arguments at all.

CORRECTION 1: (corrected argument_
    if (!overwrite) {
        char ch = 0;
        const size_t len = GetEnvironmentVariableA(name, &ch, 1);
        if (len > 0) {
            return 0;  /* asked not to overwrite existing value. */
        }
    }

CORRECTION 2: (stripped of unneeded code)
    if (!overwrite) {
        if (GetEnvironmentVariableA(name, NULL, 0) > 0) {
            return 0;  /* asked not to overwrite existing value. */
        }

Sam Lantinga 79a846d486 Fixed bug 3334 - SDL_ShowMessageBox uses wrong index and accesses un-allocated memory
romain.lacroix

For the windows implementation of SDL_ShowMessageBox() : ./src/video/windows/SDL_windowsmessagebox.c:345 WIN_ShowMessageBox()

The implementation in 2.0.4 uses "button index" for parameter "id" of function AddDialogButton().

It then expects the value provided in param wParam of function MessageBoxDialogProc() to be a valid index of a button.

It uses this value to index in the array of buttons when DialogBoxIndirect() returns (line 474 : *buttonid = buttons[which].buttonid;)

However, when dismissing this box with Escape, the return value of DialogBoxIndirect will be SDL_MESSAGEBOX_BUTTON_ESCAPEKEY_DEFAULT (=2) which is not always a valid index of array buttons.

When the array buttons has a length less or equal than 2, the memory access is invalid; I can see that the value written to *buttonId is uninitialized memory (random value).

The fix I propose : use value "buttonid" (field of button) for parameter "id" of AddDialogButton(), then copy return value of DialogBoxIndirect() in *buttonid. This way, we will not use an out-of-bounds index in array buttons.

Sam Lantinga 1da252c2d8 Fixed crash in bug 3367 - RGBA_FROM_PIXEL macro can't handle SDL_PIXELFORMAT_ARGB2101010
Simon Hug

The RGBA_FROM_PIXEL macro in src/video/blit.h [1] is not designed to work with more than 8 bits per channel and the ARGB2101010 format makes it read outside of the array bounds causing access violations. This can happen during blitting with the BlitNtoNPixelAlpha and SDL_Blit_Slow functions.

When SDL_InitFormat tries to calculate the loss of the channels [2], the Uint8 will wrap around and it will end up at 254 for the 10-bit channels. Clearly way over the 9 entries of the SDL_expand_byte array. (Not that a signed integer would help.) Then the macro tries to access the lookup table with the channel value which could be up to 1023. If the previous indirection didn't cause an access violation this one will.

I guess it's not worth modifying this macro for a format that only a few will use. It will only make the other blitters slower. I don't have good ideas to solve this issue.

Attached is a test case that does three blits. A copy one that work and the two that use the functions mentioned above.

Sam Lantinga 658975f381 Fixed bug 3639 - SDL_GetPrefPath returns a path with two consecutive slashes on Unix if org is omitted
Fabian Greffrath

we use SDL_GetPrefPath() in Chocolate Doom to get a reasonable directory to save and restore config files and savegames:

https://github.com/chocolate-doom/chocolate-doom/blob/sdl2-branch/src/m_config.c#L2162

However, since there is no "organization" behind Chocolate Doom and there is really only one "product" called Chocolate Doom, we pass an empty string for the org parameter and the package string for app.

This leads to two consecutive slashes in the path returned by SDL_GetPrefPath() like this:

/home/user/.local/share//chocolate-doom/

While this is harmless, it sure looks bad.

I believe that it should be possible to either pass a NULL pointer for the org parameter or at least have the function detect an empty string as a means to express "there is no origanization, just a single product". The generation of the path string to be returned by the function will have to get adapted accordingly.

Eric Wasylishen 2017-07-26 18:42:58 UTC
I set up an (admittedly exotic) 3-monitor setup, and when I enter fullscreen-desktop on the middle display (#2), the SDL window is off center. (covers half of monitor #2 and most of monitor #3).

The displays are arranged from left to right:

Display #1 (main): 2880x1800, 200% scaling
Display #2: 1920x1200, 150% scaling
Display #3: 1920x1080, 100% scaling

SDL display bounds:
INFO: Bounds: 1440x900 at 0,0
INFO: Bounds: 1281x801 at 1921,0  (these are incorrect)
INFO: Bounds: 1920x1080 at 4800,0

Correct bounds reported by calling EnumDisplayMonitors and printing the LPRECT param of the callback:
1440x900 at (0, 0)
1280x800 at (2880, 0)
1920x1080 at (4800, 0)

It seems like you need 3 displays to reproduce this, and the left two need DPI scaling, and the 3rd display needs to have a different scale factor than the others.

SDL: current hg (11235:6a587b9e0ec8)
Windows 10, Version 10.0.15063 Build 15063
Tested with testdraw2 and testgl2, and pressing alt+enter to enter fullscreen desktop.

This patch reworks SDL_windowsmodes.c to use EnumDisplayMonitors instead of EnumDisplayDevices, so we always have an HMONITOR for each SDL display.

With access to an HMONITOR, we can get the monitor bounds in virtual screen coordinates the proper way, by calling GetMonitorInfo. (whereas the original code was doing some calculations - e.g. "data->DeviceMode.dmPosition.x * data->ScaleX" - to try to get virtual screen coordinates. These worked in simple cases, but failed in more complex cases like this bug)

The one potential problem with my patch is, the ChangeDisplaySettingsEx docs say that you're supposed to get the display name from EnumDisplayDevices, but I'm getting the display name from GetMonitorInfo now.

Sam Lantinga 9dbe5a9686 Fixed bug 3311 - Broken touch positions with SDL_RenderSetLogicalSize & HIGHDPI on iOS
Eric wing

Hi, I think I found a bug when using SDL_WINDOW_ALLOW_HIGHDPI with SDL_RenderSetLogicalSize on iOS. I use SDL_RenderSetLogicalSize for all my stuff. I just tried turning on SDL_WINDOW_ALLOW_HIGHDPI on iOS and suddenly all my touch/mouse positions are really broken/far-off-the-mark.

I actually don't have a real retina device (still) so I'm seeing this using the iOS simulator with a 6plus template.

Attached is a simple test program that can reproduce the problem. It uses RenderSetLogicalSize and draws some moving happy faces (to show the boundaries/space of the LogicalSize and that it is working correctly for that part).

When you click/touch, it will draw one more happy face where your button point is.

If you comment out SDL_WINDOW_ALLOW_HIGHDPI, everything works as expected. But if you compile with it in, the mouse coordinates seem really far off the mark. (Face appears far up and to the left.)


Alex Szpakowski on the mailing list suggests the problem is
"I believe this is a bug in SDL_Render?s platform-agnostic mouse coordinate scaling code. It assumes the units of the mouse coordinates are always in pixels, which isn?t the case where high-DPI is involved (regardless of whether iOS is used) ? they?re actually in ?DPI independent? coordinates (which matches the window size, but not the renderer output size)."

Additionally, if this is correct, the Mac under Retina is also probably affected too and "as well as any other platform SDL adds high-dpi support for in the future".

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

Eric Wasylishen

I think I found a better fix.

The problem with https://hg.libsdl.org/SDL/rev/ebdc0738b1b5 is setting the styleMask to 0 clears the NSWindowStyleMaskFullScreen bit, which then confuses Cocoa later when you try to leave fullscreen. Instead I'm just clearing the NSWindowStyleMaskResizable bit, although SetWindowStyle(window, NSWindowStyleMaskFullScreen); seems to also work.

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.

Sam Lantinga 177f19aff0 Fixed bug 3410 - SDL_WINDOW_HIDDEN flag is inaccurate.
Jason Wyatt

After hiding the window, SDL_WINDOW_HIDDEN/SDL_WINDOW_SHOWN flags on a window are correctly updated. However on the next SDL_PumpEvents, they are set incorrectly.

This appears to be because X11_GetNetWMState does not check whether the _NET_WM_STATE property exists (it shouldn't on unmapped windows, see https://specifications.freedesktop.org/wm-spec/wm-spec-1.3.html#idm140130317598336). This results in an empty list of atoms for the state, which would imply that the window is not hidden.

(Seen on Fedora 24, Gnome)

--

Dan Ginsburg

More details on my proposed patch: I am on Kubuntu 16.04.2.  I ran into this same bug, but with Jason's patch I found that actualType != None was true so the SDL_WINDOW_HIDDEN would still not be set.  My fix instead is to explicitly check for whether the window is unmapped rather than relying on the returned values in XGetWindowProperty.

Sam Lantinga 36998b823e Fixed bug 3689 - MMX YUV renderer crash
felix

The functions in src/render/SDL_yuv_mmx.c contain the following inline assembly snippet:

        /* tap dance to workaround the inability to use %%ebx at will... */
        /*  move one thing to the stack... */
        "pushl $0\n"  /* save a slot on the stack. */
        "pushl %%ebx\n"  /* save %%ebx. */
        "movl %0, %%ebx\n"  /* put the thing in ebx. */
        "movl %%ebx,4(%%esp)\n"  /* put the thing in the stack slot. */
        "popl %%ebx\n"  /* get back %%ebx (the PIC register). */

Here's how it ended up in a binary on my old laptop:

   0xb5c17dbd <ColorRGBDitherYV12MMX1X+93>:	push   $0x0
   0xb5c17dbf <ColorRGBDitherYV12MMX1X+95>:	push   %ebx
   0xb5c17dc0 <ColorRGBDitherYV12MMX1X+96>:	mov    0xc(%esp),%ebx
   0xb5c17dc4 <ColorRGBDitherYV12MMX1X+100>:	mov    %ebx,0x4(%esp)
   0xb5c17dc8 <ColorRGBDitherYV12MMX1X+104>:	pop    %ebx

Apparently the compiler, oblivious to the fact that the assembly snippet manipulates the %esp register, decided to refer to the operand via that same register instead of via %ebp (I believe -fomit-frame-pointer enables this). This causes %ebx to be loaded with the wrong value, which later leads to a null pointer dereference.

Recent GCC can use the %ebx register normally: <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=47602#c16>. There is even an explicit constraint "b" for allocating it.

Sam Lantinga 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").

Sam Lantinga 74ca16547c Fixed bug 3699 - Shaped windows are distorted unless width is divisible by 8
Bogomancer

On X11, windows created using the shaped window API appear distorted unless the width of the shape surface is divisible by 8.

Steps to reproduce:

    1) Use your favorite image editor to resize one of the images in test/shapes/ to a width that's not a multiple of 8.
    2) Compile and run test/testshape.c on the image you edited.
    3) The shaped window will appear twisted and distorted.

It appears the bug was not caught sooner because all the test images are either 640 or 256 pixels wide.

I tracked down the bug to SDL_CalculateShapeBitmap() in SDL_shape.c. The shape surface is reduced to a 1-bit-per-pixel mask, but the original code doesn't take into account that X11 apparently wants each scanline to begin on a new byte.

Sam Lantinga cd79d8ccec Fixed bug 3696 - SDL_ShowMessageBox displays different error from intended
Mark Callow

SDL_ShowMessageBox calls SDL_CaptureMouse which, in the UIKit driver, raises a ?That operation is not supported? error, overwriting the SDL error that an application may be trying to report.

This is because UIKit SDL_CaptureMouse returns SDL_Unsupported() which ends up calling SDL_SetError() which has the following code:

    /* If we are in debug mode, print out an error message */
    SDL_LogDebug(SDL_LOG_CATEGORY_ERROR, "%s", SDL_GetError());

The SDL_GetError call here overwrites the static buffer?..

Although an application can avoid this by using SDL_GetErrorMsg(char* errstr,  int maxlen) to avoid the static buffer, SDL should be fixed.

The fix is simple. In SDL_SetError change

    SDL_LogDebug(SDL_LOG_CATEGORY_ERROR, "%s", SDL_GetError());

to

    SDL_LogDebug(SDL_LOG_CATEGORY_ERROR, "%s", error);

where error is the pointer to the buffer where it assembled the message.

Sam Lantinga 37722d01a8 Fixed bug 3697 - Main thread gets stuck on left mouse down
Amruth Raj

- My app runs in full screen to play video(I use SDL_WINDOW_FULLSCREEN_DESKTOP)
- Cmd-tab to go out of full screen to another app
- Cmd-tab again to get back to my app
- Press left mouse button at one of the edges of the screen, don't release yet.
After this point the main thread is stuck until I release the left mouse button and hence video rendering doesn't happen anymore.

On debugging more, I see that thread 0 is stuck as shown below with sendEvent processing left mouse down. It comes out only after it receives a left mouse up. There are some frames below which show NSWindowResizing, but my window flag doesn't have SDL_WINDOW_RESIZABLE set.

Sam Lantinga 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.

Ryan C. Gordon 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().

Ryan C. Gordon fc4402e5ff coreaudio: Better handling of audio buffer queue management.
We don't fill buffers just to throw them away during shutdown now, we let the
AudioQueue free its own buffers during disposal (which fixes possible warnings
getting printed to stderr by CoreAudio), and we stop the queue after running
any queued audio during shutdown, which prevents dropping the end of the
audio playback if you opened the device with an enormous sample buffer.

Ryan C. Gordon 793c788b1c coreaudio: dynamically allocate AudioQueueBuffers.
We need more than two buffers to flip between if they are small, or CoreAudio
won't make any sound; apparently it needs X milliseconds of audio queued when
it needs to play more or it drops any queued buffers. We are currently
guessing 50 milliseconds as a minimum, but there's probably a more proper
way to get the minimum time period from the system.

Ryan C. Gordon 93a6191cdc emscripten: keep track of pointer lock losses and maybe regrab pointer later.
If an Emscripten app is in relative mouse mode and the user presses Escape
(or whatever is appropriate), then the pointer lock is broken by the browser.

This keeps track of those losses, and next time the user presses a mouse
button down on the canvas, if the app is still meant to be in relative mouse
mode, we will attempt to regrab the pointer.

This makes it much more seamless for things like first-person shooters, and
the app doesn't need any manual intervention.

if the current default goes away. That will be fixed by implementing the

of this.

Capture also will now fire the callback in these conditions, offering nothing
but silence.

Apps can check SDL_GetAudioDeviceStatus() or listen for the

an opened audio device that has been unexpectedly lost.

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.

Sam Lantinga cf31ea1478 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.

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.

This currently favors libsamplerate over the fast path (quality over speed),

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.

Removing this conditional makes the resampler 10-20% faster. Left an
assert in there for debug builds, in case this still happens.

Sam Lantinga b0c5ceef7d 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.

Sam Lantinga 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.

Ryan C. Gordon 23020f92fa 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.

Sam Lantinga 4e9c9fce13 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.

Sam Lantinga 49292705a9 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.

Sam Lantinga 9d9e92cf46 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.

Sam Lantinga 356c2eadf4 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"...

Sam Lantinga 41be9756f0 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.

Sam Lantinga 082132a70c 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.

Sam Lantinga 2ba66d0525 Fixed bug 3535 - Misplaced comment #if/#endif closure comment
Coriiander

This notice is about a misplaced comment.

Often times when we use an #if #endif sequence, the #endif is followed by a comment to indicate what #if statement it belonged to. The SDL_xaudio2.c file contains a misplaced comment, as follows (I stripped the other comments):

#ifdef __GNUC__
#  define SDL_XAUDIO2_HAS_SDK 1
#elif defined(__WINRT__)
#  define SDL_XAUDIO2_HAS_SDK
#include "SDL_xaudio2.h"
#else
#if 0
#include <dxsdkver.h>
#if (!defined(_DXSDK_BUILD_MAJOR) || (_DXSDK_BUILD_MAJOR < 1284))
#  pragma message("Your DirectX SDK is too old. Disabling XAudio2 support.")
#else
#  define SDL_XAUDIO2_HAS_SDK 1
#endif
#endif
#endif /* 0 */



That final /* 0 */ should be moved one line up. Like this (I tabbed it out for you to make it more clear):

Sam Lantinga 880842cfdf Fixed bug 3531 - internal SDL_vsnprintf implementation access memory outside given buffer ranges
Tristan

The internal SDL_vsnprintf implementation accesses memory outside buffer. The bug existed also inside the format (%) processing, which was fixed with Bug 3441.

But there is still an invalid access, if we do not have any format inside the source string and the destination string is shorter than the format string. You can use any string for this test, as long it is longer than the buffer.

Example:

va_list argList;
char buffer[4];
SDL_vsnprintf(buffer, sizeof(buffer), "Testing", argList);

The bug is located on the 'else' branch of the format char test:

while (*fmt) {
  if (*fmt == '%') {
    ...
  } else {
    if (left > 1) {
      *text = *fmt;
      --left;
    }
    ++fmt;
    ++text;
  }
}
if (left > 0) {
  *text = '\0';
}

As you can see that text is always incremented, even when left is already one. When then on the last lines, *text is assigned the NULL char, the pointer is located outside bounds.

felix

Compiling even a simple SDL2 'hello world' program with gcc -Wstrict-prototypes (GCC 6.2.1) results in warnings like:

/usr/include/SDL2/SDL_gamecontroller.h:143:1: attention : function declaration isn't a prototype [-Wstrict-prototypes]
 extern DECLSPEC int SDLCALL SDL_GameControllerNumMappings();
 ^~~~~~

It seems there is a missing 'void' between the parentheses.

David Ludwig d6bcec8f6a WinRT: build fixes
These fixes are lumped into two categories:

1. add new file, SDL_dataqueue.c, to UWP/WinRT build-inputs (via MSVC project
   files)

2. implement a temporary, hack-fix for a build error in SDL_xinputjoystick.c.
   Win32's Raw Input APIs are, unfortunately, not available for use in UWP/WinRT
   APIs.  There does appear to be a replacement API, available in the
   Windows.Devices.HumanInterfaceDevice namespace.

   This fix should be sufficient to get SDL compiling again, without affecting
   Win32 builds, however using the UWP/WinRT API (in UWP/WinRT builds) would
   almost certainly be better (for UWP/WinRT builds).

   TODO: research Windows.Devices.HumanInterfaceDevice, and use that if and as
   appropriate.

Ozkan Sezer

With rev. 10651, i.e. http://hg.libsdl.org/SDL/rev/747a6a795b21 ,
SDL2 - OS X builds fail to run on 10.6 (my setup: i686 / 10.6.8)

The SDK listing it for 10.7+ does seem correct.  Reverting r10651

Sam Lantinga 4905cd9c09 Fixed bug 3340 - SDL_BlitScaled causes access violation in some cases.
Simon Hug

The SDL_BlitScaled function runs into an access violation for specific blit coordinates and surface sizes. The attached testcase blits a 800x600 surface to a 1280x720 surface at the coordinates -640,-345 scaled to 1280x720. The blit function that moves the data then runs over and reads after the pixel data from the src surface causing an access violation.

I can't say where exactly it goes wrong, but I think it could have something to do with the rounding in SDL_UpperBlitScaled. final_src.y is 288 and final_src.h is 313. Together that's 601, which I believe is one too much, but I just don't know the code enough to make sure that's the problem.

Sylvain

I think this patch fix the issue, but maybe it's worth re-writing "SDL_UpperBlitScaled" using SDL_FRect.

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)

Building SDL 2.0.5, or even the Mercurial snapshot (r10608) with GCC 6.2.1 and --enable-video-directfb generates a number of compiler diagnostics and fails.

Sam Lantinga ab8bd3d96b Fixed bug 3359 - Software renderer does incorrect blending with SDL_RenderCopyEx
Simon Hug

The software renderer produces incorrect results when blending textures at an angle with certain blend modes. It seems that there were some edge cases that weren't considered when the SW_RenderCopyEx function was last changed. Or another bug possibly covered up the problem. (More on that in another bug report.)

Most of the issues come from the fact that the rotating function sets a black colorkey. This is problematic because black is most likely appearing in the surface and the final blit will ignore these pixels. Unless a colorkey is already set (the software renderer currently never sets one), it's very hard to find a free color. Of course it could scan over the whole image until one is found, but that seems inefficient.

The following blend modes have issues when drawn at an angle.

NONE: The black pixels get ignored, making them essentially transparent. This breaks the 'dstRGBA = srcRGBA' definition of the NONE blend mode.

MOD: Again, the black pixels get ignored. This also breaks the 'dstRGB = dstRGB * srcRGB' definition of the MOD blend mode, where black pixels would make the destination black as well. A white colorkey will work though, with some preparations.

BLEND: There are some issues when blending a texture with a translucent RGBA target texture. I - uh - forgot what the problem here exactly is.

This patch fixes the issues mentioned above. It mainly changes the code so it tries to do things without the colorkey and removes the automatic format conversion part from the SDLgfx_rotateSurface function. Getting the format right is something the caller has to do now and the required code has been added to the SW_RenderCopyEx function.

There's a small change to the SW_CreateTexture function. RLE encoding a surface with an alpha mask can be a lossy process. Depending on how the user uses the RGBA channels, this may be undesired. The change that surfaces with an alpha mask don't get encoded makes the software renderer consistent with the other renderers.

The SW_RenderCopyEx function now does these steps: Lock the source surface if necessary. Create a clone of the source by using the pixel buffer directly. Check the format and set a flag if a conversion is necessary. Check if scaling or cropping is necessary and set the flag for that as well. Check if color and alpha modulation has to be done before the rotate. Check if the source is an opaque surface. If not, it creates a mask surface that is necessary for the NONE blend mode. If any of the flags were set, a new surface is created and the source will be converted, scaled, cropped, and modulated. The rest of the function stays somewhat the same. The mask also needs to be rotated of course and then there is the NONE blend mode...

It's surprisingly hard to get the pixel from a rotated surface to the destination buffer without affecting the pixel outside the rotated area. I found a way to do this with three blits which is pretty hard on the performance. Perhaps someone has an idea how to do this faster?

As mentioned above, the SDLgfx_rotateSurface now only takes 8-bit paletted or 32-bit with alpha mask surfaces. It additionally sets the new surfaces up for the MOD blend mode.

I shortly tested the 8-bit path of SDLgfx_rotateSurface and it seemed to work so far. This path is not used by the software renderer anyway.

if you set a dummy colorkey, it will remove the line ...
if you set a some alpha mod, the +90/-90 get transparent but not the 0/180  ...

Sam Lantinga 23c01c1890 Fixed bug 3079 - Allow non destructive SDL_GameControllerAddMappingsFromFile
x414e54

It is a bit of a pain to update the library or rely on whatever version the user has on their computer for default mappings.

So providing an easily updatable text file via SDL_GameControllerAddMappingsFromFile is still currently the most viable way. However using this replaces all mappings provided by the SDL_HINT_GAMECONTROLLERCONFIG environment variable which may have come from the user's custom Steam mapping.

There should be an easy way for games to supply extra game controller mappings to fill in the differences between SDL versions without it clobbering the SDL_HINT_GAMECONTROLLERCONFIG environment variable.

Internally the mappings could use a priority system and if the priority is lower then it will not overwrite the mappings.

For now it just assumes SDL_HINT_GAMECONTROLLERCONFIG is the highest priority, the default hardcoded are the lowest and anything set via the API is medium.

Sam Lantinga 40b571c91e Fixed bug 3468 - _allshr in SDL_stdlib.c is not working properly
Mark Pizzolato

On Windows with Visual Studio, when building SDL as a static library using the x86 (32bit) mode, several intrinsic operations are implemented in code in SDL_stdlib.c.

One of these, _allshr() is not properly implemented and fails for some input.  As a result, some operations on 64bit data elements (long long) don't always work.

I classified this bug as a blocker since things absolutely don't work when the affected code is invoked.  The affected code is only invoked when SDL is compiled in x86 mode on Visual Studio when building a SDL as a static library.  This build environment isn't common, and hence the bug hasn't been noticed previously.

I reopened #2537 and mentioned this problem and provided a fix.  That fix is provided again here along with test code which could be added to some of the SDL test code.  This test code verifies that the x86 intrinsic routines produce the same results as the native x64 instructions which these routines emulate under the Microsoft compiler.  The point of the tests is to make sure that Visual Studio x86 code produces the same results as Visual Studio x64 code.  Some of the arguments (or boundary conditions) may produce different results on other compiler environments, so the tests really shouldn't be run on all compilers.  The test driver only actually exercised code when the compiler defines _MSC_VER, so the driver can generically be invoked without issue.

This no longer uses a script to generate code for every possible type

times. Now we use a handful of more generic functions and assume staying in
the CPU cache is the most important thing anyhow.

This shrinks the size of the final build (in this case: macOS X amd64, -Os to
optimize for size) by 15%. When compiling on a single core, build times drop
by about 15% too (although the previous cost was largely hidden by multicore
builds).

Sam Lantinga 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.

Sam Lantinga ae8ca7c54d Fixed bug 3444 - Android-TV: no more handling of back button on remote
ny00

Unfortunately, simply checking the return codes of "onNativePadDown/Up" as previously done has its own issue:

If an SDL joystick is connected *and* opened, then a proper KeyEvent, say with keycode KEYCODE_BUTTON_1, should lead to an SDL joystick button event as expected.

If, however, the joystick was *not* opened, then "onNativePadDown/Up" will return a negative value, so before the commit from bug 3426, you could unexpectedly get a keyboard event. (In practice, you'll just get a log message, since KEYCODE_BUTTON_1 has no mapping to a proper SDL_ScanCode value, but it's still an problem).

What should still be done, though, is checking the key code itself. We do have the KeyEvent.isGamepadButton method, but according my test, it returns "true" exactly (and only) for the KEYCODE_BUTTON* values, and not for KEYCODE_DPAD* or any other key code.

Here is a possible solution:
- Do check the return codes of "onNativePadDown/Up" as previously done.
- In addition, in "Android_OnPadDown/Up" from src/joystick/android/SDL_sysjoystick.c, 0 should *always* be returned in case the key code can be translated to an SDL_joystick button; Even if no matching joystick can be found.

There are currently three entry points in the SDL2_main code for windows: main, wmain and WinMain. Only the latter two properly convert the arguments to UTF-8.

Console applications linked with MSVC will always link with the main entry point (wmain has to be selected by manually setting the entry point). This makes it likely that such programs will not have proper unicode arguments.

Sam Lantinga 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.

Sam Lantinga 063f752e0d Fixed bug 3328 - Race condition in Wayland_VideoInit
Robert Folland

When running this little test program with SDL2 on Wayland it often crashes in SDL_Init.

From a backtrace it is apparent that there is a race condition in creating a xkb_context_ref. Sometimes it is 0x0.

By moving the relevant lines higher up in Wayland_VideoInit (in SDL2-2.0.4/src/video/wayland/SDL_waylandvideo.c:302) this seems to get fixed.

I moved the call to WAYLAND_xkb_context_new() up to before the call to WAYLAND_wl_display_connect().

Here is the test program (just a loop of init and quit), and a backtrace from gdb:

#include <cstdio>
#include <stdlib.h>
#include <SDL2/SDL.h>
#include <unistd.h>
#include <iostream>

int main(int argc, char **argv)
{
    int count = atoi(argv[1]);

    for (int i = 0; i < count; i++) {
        std::cout << "Init " << i << std::endl;
        if (SDL_Init(SDL_INIT_VIDEO) < 0) {
            SDL_LogError(SDL_LOG_CATEGORY_APPLICATION,
                         "Couldn't initialize SDL: %s\n",
                         SDL_GetError());
            return 1;
        }
        std::cout << "Quit" << std::endl;
        SDL_Quit();
    }
    return 0;
}

Sam Lantinga f94bd05736 Fixed bug 3451 - Raspberry Pi Raspbian SDL_assert triggered sometimes at RPI_WarpMouseGlobal
Eric wing

Sometimes an SDL_assert triggers at RPI_WarpMouseGlobal
src/video/raspberry/SDL_rpimouse.c:232 'update'.

It doesn't always reproduce, but it seems to happen when you really bog down the system and the event loop can't update for awhile.


The first time I hit this, I wasn't even using the mouse. I don't call any warp mouse functions either.


I can usually reproduce with a simple program that runs an expensive blocking CPU series of functions which blocks the main loop until complete (can be up to 10 seconds).

Sometimes this assertion gets triggered after that. I'm not sure if
they are related or coincidental.


Disabling the SDL_asserts when compiling SDL will avoid this problem. I actually haven't seen any problems with the mouse when I do this.

On a Raspberry Pi 2 running Raspbian Jessie.

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.

Sam Lantinga eea76fc199 Fixed bug 3063 - Wayland: SDL resizes EGL surface to 0x0.
x414e54

Wayland will sometimes send empty resize events (0 width and 0 height) to the client. I have not worked out the exact conditions a client would receive these but I can assume it might be if the window is offscreen or not mapped yet.

This causes issues with some SDL clients as they receive the 0x0 event and unexpected resize event or might not request to resize back to the correct size.

As per the wl_shell Wayland spec configure events are only a suggestion and the client is free to ignore or pick a different size (this is how min/max and fixed aspect ratio is supped to be implemented).

A patch is attached but is just the first iteration and I will fix any issues such as checking for FULLSCREEN/MAXIMIZED or RESIZABLE flags unless someone else fixes this first.

I have update to take into account non resizable and fullscreen windows. Also adding in maximize/restore and title functions for Wayland.

Darren Kulp

The dummy video driver is not available on Mac OS X if SDL_VIDEO_OPENGL is set at library compilation time.

In src/video/SDL_video.c, there is a compile-time check in SDL_CreateWindow() for (SDL_VIDEO_OPENGL && __MACOSX__). When it succeeds, SDL_WINDOW_OPENGL is always requested. Since the dummy video driver does not supply an OpenGL implementation, the error "No OpenGL support in video driver" is supplied to the user, and SDL_CreateWindow() is exited early.

Sam Lantinga 9c48365524 Fixed bug 3029 - software renderer cuts off edges when rotate-blitting with a multiple of 90 degrees
Adam M.

When doing a rotated texture copy with the software renderer, where the angle is a multiple of 90 degrees, one or two edges of the image get cut off. This is because of the following line in sw_rotate.c:
    if ((unsigned)dx < (unsigned)sw && (unsigned)dy < (unsigned)sh) {
which is effectively saying:
    if (dx >= 0 && dx < src->w-1 && dy >= 0 && dy < src->h-1) {

As a result, it doesn't process pixels in the right column or bottom row of the source image (except when they're accessed as part of the bilinear filtering for nearby pixels). This causes it to look like the edges are cut off, and it's especially obvious with an exact multiple of 90 degrees.

As stated in Summary. The switch statement will execute the default case and set a SDL error message: "SDL_MixAudio(): unknown audio format".

There are atleast two more problems here:

1. SDL_MixAudioFormat does not notify the user that an error has occured and that a SDL error message was set. It took me awhile to understand why I couldn't mix down the volume on my AUDIO_U16LSB formatted audio stream.. until I started digging in the SDL source code.

2. The error message is incorrect, it should read: "SDL_MixAudioFormat(): unknown audio format".

Sam Lantinga 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);

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.

Jan Klass

Not sure if this is limited to the joystick subsystem,
but I created a minimal program for reproducibility,
which is attached.

The issue occurs with my gamepad Razer Onza (an xbox-style gamepad) plugged in.
On initialization, the gamepad is being recognized.
After quitting the subsystem, the poll will receive the joystick added event,
which it instantly handles itself, calling SDL_SYS_JoystickDetect again,
which this time calls IDirectInput8_EnumDevices with dinput = NULL (after it was released on quit).
This seems to lead to an access violation within said function, which I have no source for.

Sam Lantinga dac3892816 Fixed bug 2832 - Inverted arrow-key navigation in MessageBox
Jan Hellwig

On Windows, you are able to navigate between the buttons on a MessageBox that was created using SDL_ShowMessageBox using the arrow keys. However, if you press the left arrow key, the selection jumps to the button on the right of the currently selected one (and vice versa).

This can be fixed by reversing the order in which the buttons are added to the dialog.

The attached patch files fixes this problem. However the first press of an arrow key leads to the selection of the leftmost or rightmost button on the MessageBox, not to the selection of the button left/right of the one that is selected by default.

Sam Lantinga 72164985b0 Fixed bug 2823 - Release events for triggers receive wrong centered value
Ryochan7

I have been using SDL 2 for a little project that I have been developing for a while. My project is called antimicro and it takes gamepad input and then translates gamepad events into keyboard and mouse events. SDL is used to read the input from an XInput gamepad and it works great for the most part. However, there is one glaring problem that I have encountered.

When a device is unplugged and SDL sends the centered value release events for all axes, buttons, and hats, SDL does not use the proper centered value for the triggers. It pushes an SDL_JOYAXISMOTION event onto the queue with a value of 0 for all axes. That value is converted to around 16,000 for a Game Controller. That value is incorrect for triggers and, in my program, that causes any bindings that are assigned to the triggers to get activated. With most profiles, that will typically mean that a mouse right click and left click will be activated before the device is finally seen as removed and then those bindings are released by antimicro.

Sam Lantinga f674f2311a Fixed bug 2808 - Fix SDL reporting wrong window size on resume
Jonas Kulla

At startup time, the single android window is assigned a "windowed" (window->windowed.{w,h}) size based on the current orientation of the mobile device; this size is never updated throughout the lifetime of the app.

This becomes problematic when the app is paused and then resumed in an orientation that it did not start up in. Eventually, 'SDL_OnWindowRestored()' is called, which calls 'SDL_UpdateFullscreenMode()'. This function is very problematic because it is written with a desktop monitor in mind: it tries to find a matching display mode for the windowed size, doesn't find any, and finally applies the windowed size as the fullscreen one. In the end, the windowed size is reported in a RESIZED event, which doesn't correspond to the actual surface size.

To see this in action: Start an orientation aware SDL app in eg. portrait mode, suspend the app, put the device into landscape orientation and resume the app. It will erroneously render in portrait mode (until the device is rotated again).

Ryan C. Gordon f6a280ab7f audio: Don't trust audio drivers to drain pending audio.
This tends to be a frequent spot where drivers hang, and the waits were
often unreliable in any case.

Instead, our audio thread now alerts the driver that we're done streaming audio
(which currently XAudio2 uses to alert the system not to warn about the
impending underflow) and then SDL_Delay()'s for a duration that's reasonable
to drain the DMA buffers before closing the device.

Sam Lantinga 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?

Sam Lantinga 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.

Ryan C. Gordon 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."

Sam Lantinga 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.

Sam Lantinga 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.

Sam Lantinga 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.

Sam Lantinga 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.

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.

The SDLmain file src/main/windows/SDL_windows_main.c defines both entry points for console applications, main and wmain. This seems to confuse MSVC. It outputs a LNK4067 warning and then chooses main, which is a shame because only wmain has the unicode handling. Using SDLmain.lib provided on libsdl.org, the linker also goes for main.

I'm proposing to not define the main entry point at all. wmain should be supported well enough with MSVC.

Eric Wasylishen

The bug here is that a dead keys pressed before calling SDL_StartTextInput() carries over into future text input, so the next key pressed will have the deadkey applied to it.

This in undesirable, imho, and doesn't occur on OS X (haven't check Linux or elsewhere). It's causing a problem for Quakespasm on German keyboard layouts, where we use the ^ deadkey to toggle the console (which enables/disables text input), and ^ characters are showing up in the TEXTINPUT events.

Sam Lantinga 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.

Sam Lantinga 51d6371ec1 Fixed bug 3350 - GL renderers don't need to flip rows after reading back pixels from the target texture
Simon Hug

All OpenGL renderers always flip the rows of the pixels that come from glReadPixels. This is unnecessary for target textures since these are already top down.

Also, the rect->y value can be used directly for target textures for the same reason. I don't see any code that would handle the logical render size for target textures. Or am I missing something?

The attached patch makes the renderers only the flip rows if the data comes from the default framebuffer.

Sam Lantinga 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.)

Sam Lantinga a42c396a57 Fixed bug 3361 - Texture color modulation doesn't work with active NONE blend mode (opengl and opengles)
Simon Hug

The GL_SetBlendMode and GLES_SetBlendMode functions of the opengl and opengles renderers call the glTexEnvf to set the texture env mode to either GL_MODULATE (the default) or GL_REPLACE for the NONE blend mode. Using GL_REPLACE disables color and alpha modulation for textures.

These glTexEnv calls were put in the SetBlendMode function back in 2006 [1], but there the NONE code still used the GL_DECAL mode. The GL_REPLACE mode came in 2008 [2]. I'm a bit confused why that wasn't always GL_MODULATE and a bit surprised nobody reported that yet (unless I missed it). I guess only a few use the gles renderer and the newish shaders mask the issue.

Sam Lantinga 3f1b1629c4 Fixed bug 3362 - OpenGL renderer doesn't check if framebuffers are supported when creating target textures
Simon Hug

The GL_CreateTexture function doesn't have any checks for the case where the driver doesn't support the framebuffer object extension. It will call into GL_GetFBO which will call the non-existent glGenFramebuffersEXT.

Also, for some reason GL_CreateContext always sets the SDL_RENDERER_TARGETTEXTURE info flag, even if it is not supported. Changeset cc226dce7536 [1] makes this change, but doesn't explain why. It seems to me like the code would already have taken care of this [2].

The attached patch adds some checks and stops SDL from reporting render target support if there is none. The application can then properly inform the user instead of just crashing.

Sam Lantinga fd1d692bef Fixed bug 3368 - SDL_Blit_Slow doesn't ignore alpha values in colorkey comparison
Simon Hug

When the SDL_Blit_Slow function compares the pixel to the color key it does so without removing the alpha component from the pixel value and the key. This is different from the optimized 32-bit blitters which create a rgb mask and apply it to both to filter the alpha out. SDL_Blit_Slow will only skip the pixels with the exact alpha value of the key instead of all pixels with the same color.

The attached test case blits a surface with a color key and prints the pixel values to the console. The third row is expected to be skipped.

Sam Lantinga 2ccb46cebc Fixed bug 3373 - OpenGL implementation differences of glDrawTexfOES
Simon Hug

It seems not everyone implemented glDrawTexfOES the same. Intel and Mesa ignore the viewport entirely, whereas the Raspberry Pi implementation offsets the coordinates and does viewport clipping.

The glDrawTexfOES extension text [1] for the function says "Xs and Ys are given directly in window (viewport) coordinates." I guess this wasn't clear enough.

Alex Szpakowski

Honestly I'd probably remove that codepath from SDL_Render entirely. It's an OpenGL ES 1-specific extension that isn't likely to give huge performance gains and adds additional maintenance overhead to SDL_Render while also having bugs in some drivers (as seen here).

SFC30 controller: http://www.8bitdo.com/sfc30/

The SFC30 controller can present itself in a variety of modes and it offers up
different names in each. This patch captures data for three modes (one USB and
two Bluetooth) on three platforms (Mac OS X, Windows, Linux).

However, USB mode on Linux and Windows is missing as the button events did not
make it through to SDL's controllermap tool on Fedora 24/Linux 4.5.5 nor Steam
Big Picture mode on Windows. The two Bluetooth modes were indistinguishable on
Windows. Two modes on OS X were indistinguishable.

There exists a similar controller called the SNES30 (And some others) that are
very likely identical except for the name, but I have not verified this yet so
haven't synthesized lines for those controllers until I can.
