Sam Lantinga fb14cb7425 Fixed bug 2263 - Event timestamp members are undocumented
Charles Huber

The event timestamp members should be documented to indicate their meaning and units.

Currently the timestamps are populated using SDL_GetTicks() in SDL_PushEvent() in SDL_events.c.

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

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

Sam Lantinga f142a7961e Fixed bug 2441 - SDL_DuplicateSurface
Rainer Deyke

I've written a small patch that adds a small SDL_DuplicateSurface function to SDL.  I've written the function as part of a larger (as yet unfinished) patch, but I think this function is useful enough that it merits inclusion in SDL on its own.

2. SDL_platform.h: recognize __EMX__ too as __OS2__
3. begin_code.h: set SDLCALL as _System for OS/2.

Alexey

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

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

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

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

Simple build instructions:

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

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

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

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

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").

This patch is wrong: the structure in question has nothing to do with any
gcc version in use.  I suggest reverting this adding a conigury check for
it, instead.  Something like the following should do it: (configure needs

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().

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.

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

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

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

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 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.

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

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

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);

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

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

C.W. Betts

Swift is very strict with types, so much that those of different signedness/size must be cast. Most of the defines are imported as 32-bit signed integers, while the corresponding field in a struct is a 32-bit unsigned integer. Appending a "u" would cause the defined types to be imported as 32-bit unsigned integers.

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 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.)

When using API 21 and running on an old device (android < 5.0 ?) some function are missing.

This was the only thing that made SDL_config.h generate differently between

X11 code to match our dynamic loader version, which removes the compile error
on some machines that prompted this test in the first place.

Xlib never wrote to this data, so if you're on an older Xlib where this param
wasn't const, your data should still be intact when we force the caller to
think it was actually const after all.

which window a given drop was delivered. For application-level drops (for
example, you launched an app by dropping a file on its icon), the window ID
will be zero.

- modifications to various pieces of SDL, in order to compile via MSVC 2015 +
  the Win10 API set
- enables SDL_Window resizing and programmatic-fullscreen toggling, when using
  the WinRT backend
- WinRT README updates

David Ludwig fa2d5ab497 WinRT: bug-fix - SDL_SetThreadPriority() didn't work on WinRT 8.x platforms
WinRT 8.0 (Phone and non-Phone) didn't offer an API to set an already-created
thread's priority.  WinRT 8.1 offered this API, along with several other
Win32 thread functions that were previously unavailable (in WinRT).

This change makes WinRT 8.1+ platforms use SDL's Win32 backend.

David Ludwig 623898f70b WinRT: lots of display and windowing related fixes
This change-set fixes a lot of windowing related bugs, especially with
regards to Windows 8.x apps running on Windows 10 (which was the driver for
this work).  The primary fixes include:
* listed display modes were wrong, especially when launching apps into a
  non-fullscreen space
* reported window flags were often wrong, especially on Windows 10
* fullscreen/windowed mode switches weren't failing (they are not
  programmatically possible in Win 8.x apps).

Ryan C. Gordon e346f14277 SDL_WarpMouseGlobal() should return non-void.
There are platforms it isn't implemented on (and currently can't be
implemented on!), and there's currently no way for an app to know this.

This shouldn't break ABI on apps that moved to a revision between 2.0.3 and
2.0.4.

Philipp Wiesemann 0e45984fa0 Fixed crash if initialization of EGL failed but was tried again later.
The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly
uninitialized data structure if loading the library first failed. A later try to
use EGL then skipped initialization and assumed it was previously successful
because the data structure now already existed. This led to at least one crash
in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was
dereferenced to make a call to eglBindAPI().

Ryan C. Gordon a0e878aafb Minor input grab clarifications.
Clarify that grabbing the mouse only works with one window at a time; this was
always true at the system level, though SDL could previously get confused
by multiple simultaneous grabs, so now we explicitly break any existing
grab before starting a new one and document it as such.

Also track the window that is currently grabbed, and provide an API to query
for that window. This makes it easy to automate mouse ungrabbing at
breakpoints with gdb7's scripting, since the scripts can now know which window
to ungrab.

In 2.1, we should probably change this API to SDL_GrabInput(win) and
SDL_UngrabInput(void), or something.

Marc Di Luzio f5d96416ad Allow setting of GL_CONTEXT_RELEASE_BEHAVIOR when creating the GL context when GLX_ARB_context_flush_control is available.
This extension allows the user to specify whether a full flush is performed when making a context not current.
The only way to set this currently is at context creation, so this patch provides that functionality.
Defualt behaviour is set at FLUSH, as per the spec.

This patch does not contain the changes to WGL, appleGL or other platforms as I do not have access to GL 4.5 hardware on those platforms.

Full details on the use of KHR_context_flush_control can be found here:

at all.

Ryan C. Gordon 483ea8b7b0 Fixed SDL_PRI?64 for 64-bit Linux.
64-bit Linux uses a "long" instead of "long long" for 64-bit ints.

when used with SDL's 64-bit datatypes on 64-bit Linux.

Edward Rudd b88ca1b4a6 the last parameter of XChangeProperty is the number of elements.. and when the element format is 32.. the element is "long" so we have 5 long elements here.
Yes this seems confusing as on mac+linux Long is either 32 or 64bits depending on the architecture, but this is how the X11 protocol is defined. Thus 5 is the correct value for the nelts here.  Not 5 or 10 depending on the architecture.

Alex Szpakowski 01bfc2158a Several improvements to the iOS backend:
- Added new custom launch screen code. It uses the launch screen nib when available on iOS 8+, the launch images dictionary if the launch screen nib isn't available, and the old standard image names if the launch image dictionary isn't in the plist.
The launch screen is now hidden during the first call to SDL_PumpEvents rather than SDL_CreateWindow so apps can have the launch screen still visible if they do time-consuming loading after creating their window. It also fades out in roughly the same way as the system launch screen behavior.
It can be disabled by setting the SDL_IPHONE_LAUNCHSCREEN define in SDL_config_iphoneos.h to 0.

- A blank UIView is now created and displayed when the window is first created. The old behavior was to defer creating any view until SDL_GL_CreateContext, which prevented rotation, touch events, and other windowing-related things from working until then. This also makes it easier to use SDL_GetWindowWMInfo after creating a window.

- Moved the keyboard and animation callback code from SDL's UIView subclasses to its UIViewController subclass, which lets them work properly in all cases when a SDL window is valid, even before SDL_GL_CreateContext is called and after SDL_GL_DeleteContext is called.

- SDL_GL_CreateContext, SDL_GL_SwapWindow, SDL_GL_MakeCurrent, and SDL_GL_DeleteContext are more robust.

- Fixed some edge cases where SDL windows weren't rotating properly or their reported sizes were out of sync with their actual sizes.

- Removed all calls to [UIApplication setStatusBarOrientation:]. It doesn't seem to work as expected in all cases in recent iOS versions.

- Some code style cleanup.
