Sam Lantinga b54bcb34d0 Fixed bug 3483 - Steelseries Nimbus MFi controller reversed Y-axis analog stick
benjamin.feng

Probable underlying cause: https://bugzilla.libsdl.org/show_bug.cgi?id=3124#c5

"If you download and build the HID Calibrator sample you can see that these are totally legitimate HID devices (except for inverting the Y-axis of joysticks, which is contrary to the HID specification but does make them more compatible with games compiled expecting XBOX controllers)."

Sam Lantinga 92bf608527 Fixed bug 3616 - SDL_GL_CreateContext fails with SDL_GL_CONTEXT_DEBUG_FLAG and ANGLE/GLES 2.0
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.

Sam Lantinga 90b38a5d61 Fixed bug 3786 - building against a Mac OS X SDK < 10.11 fails since the vulkan merge
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.)

I cross-build against 10.8 SDK on linux using clang-3.4.2 and this
is a problem for me.  Will this be fixed?

Sam Lantinga d619d88560 Fixed bug 3662 - Error message when using the audio conversion setup without an initialized audio subsystem is a bit vague
Simon Hug

This issue actually raises the question if this API change (requirement of initialized audio subsystem) is breaking backwards compatibility. I don't see the documentation saying it is needed in 2.0.5.

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.)

Sam Lantinga 2a945b44cb Fixed bug 2361 - [Android] Joysticks do not have unique IDs
David Brady

When I attempted to make a mapping file for Android gamepads, I quickly discovered that most of the ones that I have here show up as the same device (Broadcom Bluetooth HID), meaning that it was impossible to make mappings on Android, since every device looked the same.

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.

Sam Lantinga 0560544d1c Fixed 3783 - Default libGL path for directFB on Linux differs from x11 path
Clayton Craft

The default path used by directfb for libGL is different than the default path used by x11 in SDL2:

./src/video/directfb/SDL_DirectFB_opengl.c:
path = "libGL.so";

./src/video/x11/SDL_x11opengl.c:
#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")

Sam Lantinga 8e7998e19d Fixed bug 3710 - SDL_OpenAudio(desired, obtained) doesn't update desired's size when obtained is NULL
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).

Ryan C. Gordon f5a38f234b x11: specify event mask for buttons when grabbing pointer (thanks, Stas!).
This fixes a strange corner case (notes appended below), and should be
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).

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

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 64dd829b0a Fixed bug 2418 - Structure SDL_gestureTouch leaking
Leonardo

Structure SDL_gestureTouch gets reallocated for every new added gesture but its never freed.

Proposed patch add the function SDL_GestureQuit() that takes care of doing that and gets called when TouchQuit is called.

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).

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.

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.

UX-admin

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.

Ozkan Sezer

The attached patch removes SDLCALL attribute from SDL_BlitFunc() funcptr.

As far as I can see, *SDL_BlitFunc() is completely internal to SDL with
no specific calling convention requirements.  The actual functions assigned
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)
	libpthread.so.0 => /lib/libpthread.so.0 (0xb766e000)
	libc.so.6 => /lib/libc.so.6 (0xb74e2000)
	libm.so.6 => /lib/libm.so.6 (0xb74a0000)
	libdl.so.2 => /lib/libdl.so.2 (0xb749a000)
	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)
	libxcb.so.1 => /usr/lib/libxcb.so.1 (0xb72dc000)
	libXau.so.6 => /usr/lib/libXau.so.6 (0xb72d9000)
	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.

Sam Lantinga 45cec28bc4 Fixed bug 3058 - Slight mistake in GetWindowStyle in SDL_windowswindow.c
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

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.

Ian Abbott

I just spotted what I think is a bug in "src/thread/pthread/SDL_sysmutex.c" in the SDL_TryLockMutex function when FAKE_RECURSIVE_MUTEX is defined (for an implementation of Pthreads with no recursive mutex support).  It calls pthread_mutex_lock instead of pthread_mutex_trylock, so it will block until the mutex is available instead of returning SDL_MUTEX_TIMEDOUT if it cannot lock the mutex immediately.

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.

Since SDL will overwrite the error or exit the function with a return value that indicates success, the error form SDL_LoadObject for the optional stuff might as well be cleared right away.

Sam Lantinga 6e1b11bae4 Fixed bug 3714 - Windows: SDL_WINDOW_FULLSCREEN_DESKTOP broken on 3 monitor setup w/ DPI scaling
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".

Sam Lantinga 997c69b9ef Fixed bug 3697 - Main thread gets stuck on left mouse down
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.

Sam Lantinga 6391cc3fef Backed out changeset ebdc0738b1b5 for bug 3697
Eric Wasylishen

Unfortunately this commit seems to have broken exiting desktop-fullscreen.
- Launch testgl2.
- Press alt+enter to go fullscreen-desktop
- Press alt+enter again. The spinning cube will freeze, and the window stays fullscreen desktop.

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 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.

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

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.

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

target, or not use SDL_GetWindowWMInfo().

Ryan C. Gordon 6d661cab7b windows: Change the default on SDL_HINT_WINDOWS_DISABLE_THREAD_NAMING.
It's easier for Visual Studio users that want this information to turn it on
or live without it, than it is to explain why every debugger that isn't Visual
Studio crashes out here. Eventually SetThreadDescription() will be the thing
everyone uses anyhow.

Bastien Bouclet 545fba7886 x11: Don't send duplicate events when reconciling the keyboard state
Failing to check if a key was known to be pressed by SDL was causing
SDL_SendKeyboardKey to send duplicate key pressed events with the repeat
property set to true.

Ryan C. Gordon de52dc2948 haiku: Correctly set keyboard focus (thanks, Kai!).
The message sent upon the window being activated or deactivated, to trigger
the call to SDL_SetKeyboardFocus was missing a mandatory parameter. So
keyboard focus was never properly set.

Ryan C. Gordon e5918acf46 wasapi: properly report init failure if on pre-Vista version of Windows.
We really should change the Init interface to return 0 on success and -1 on
error, like everything else, to avoid this sort of confusion.

Philipp Wiesemann 604a4b1b30 haiku: Fixed SDL_SetClipboardText() allocating too much memory and cutting text.
It allocated pointers instead of chars and passed a wrong size to SDL_strlcpy().

Ryan C. Gordon a7fc2822d4 audio: rename bsd target to netbsd.
Apparently this is no longer a generic BSD audio target, and hasn't been for
years, so rename it for NetBSD.
2017-05-24 19:56:59 -04:00
Ryan C. Gordon 6844d92c23 coreaudio: we don't need to track number of allocated audio buffers anymore.
CoreAudio takes care of iterating through the buffers and freeing them now,
so we don't have to manage this ourselves.
2017-05-24 13:28:13 -04:00
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.
