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.

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.

e4ef1885d9 Fixed bug 3890 - Incomplete fix for CVE-2017-2888
Felix Geyer

http://hg.libsdl.org/SDL/rev/a31ee4d64ff6 tries to fix CVE-2017-2888.
Unfortunately compilers may optimize the second condition "(size / surface->pitch) != surface->h" away.
See https://bugzilla.redhat.com/show_bug.cgi?id=1500623#c2
I've verified that this is also the case on Debian unstable (gcc 7.2).

f658a737f6 Fixed bug 3882 - cmake fix for osx
Ozkan Sezer

In my cross-build environment with cmake-2.8.12.1, cmake does not add
SDL_coreaudio.m to its makefiles and the result is a failure. The fix
is simple: set the language to C for it as it is done at other places
in CMakeLists.txt.

a223560a7f Fixed bug 3880 - X Error upon quit since rev. 11607
Ozkan Sezer

Since changeset 11607:60cd425a2f14, I am getting the following
error upon quit.  Running testsprite2, clicking the mouse, and
quiting it is enough to trigger it.  This is on my old Fedora9
x86-Linux:

X Error of failed request:  BadCursor (invalid Cursor parameter)
  Major opcode of failed request:  2 (X_ChangeWindowAttributes)
  Resource id in failed request:  0xb057340
  Serial number of failed request:  905
  Current serial number in output stream:  906

Reverting  https://hg.libsdl.org/SDL/rev/60cd425a2f14  removes
the error.

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.

f4cd68a537 Fixed bug 3866 - CMake error when trying to make the 'uninstall' target when it already exists
Steve Robinson

In my project, the 'uninstall' target is already created by the glew library.  I get this error when SDL2 tries to create it:

CMake Error at _build/3rdparty/SDL2/SDL2-2.0.6/CMakeLists.txt:1816 (add_custom_target):
  add_custom_target cannot create target "uninstall" because another target
  with the same name already exists.  The existing target is a custom target
  created in source directory
  "D:/Code/sdl2-tutorial/_build/3rdparty/glew/glew-2.1.0/build/cmake".  See
  documentation for policy CMP0002 for more details.

To fix it, go to the bottom of the SDL2 CMakeLists.txt file.  Add an if statement to check for the existence of the target before creating it.  The end result looks like this:

if(NOT TARGET uninstall)
  configure_file(
      "${CMAKE_CURRENT_SOURCE_DIR}/cmake_uninstall.cmake.in"
      "${CMAKE_CURRENT_BINARY_DIR}/cmake_uninstall.cmake"
      IMMEDIATE @ONLY)

  add_custom_target(uninstall
      COMMAND ${CMAKE_COMMAND} -P ${CMAKE_CURRENT_BINARY_DIR}/cmake_uninstall.cmake)
endif()

This is how the glew library deals with this possibility in their CMakeLists.txt file.

4f38db1735 Fixed bug 3867 - Can't find install_manifest.txt when running 'uninstall' target
Steve Robinson

When I try to build the 'uninstall' target in CMake when SDL2 is added to a subdirectory of my project, I get this error:

1>CMake Error at cmake_uninstall.cmake:2 (message):
1>  Cannot find install manifest:
1>  "D:/Code/sdl2-tutorial/_build/3rdparty/SDL2/SDL2-2.0.6/install_manifest.txt"

The install_manifest.txt is actually in the top-level binary directory, not the project-specific binary directory.

To fix it, change all instances of:
CMAKE_CURRENT_BINARY_DIR

To:
CMAKE_BINARY_DIR

In:
cmake_uninstall.cmake.in

c0019b7f49 Fixed bug 3871 - Touch events are not normalised on X11
Trent Gamblin

The documentation for SDL_TouchFingerEvent says that the x and y coordinates are normalised between 0-1. I've found that to be true on Windows, Android and iOS but on X11 they are in pixel coordinates. This patch fixes the issue. This was the cleanest way I could do it with what was available without changing things around a lot but you may know a better way.

42fff7ce2b audio: Don't stack-allocate resampler padding.
(I thought padding size ranged from 5 frames to ~30 frames (based around
RESAMPLER_ZERO_CROSSINGS, which is 5), but it's actually between 512 and
several thousands (based on RESAMPLER_SAMPLES_PER_ZERO_CROSSING)). It gets
big fast when downsampling.
