1f482174	2021-04-25T12:44:35	x11: Mark backing_store as NotUseful when creating windows. This can give some performance boost, and save some resources, as there's no reason to keep a copy of an SDL window's contents on the server: most SDL apps are redrawing completely every frame, and the API allows for expose events to tell an app a redraw is needed anyhow. (And compositors are free to ignore this setting if it makes sense to do so, according to the Xlib docs.) Reference Issue #3776.
9c063468	2021-04-24T19:47:10	x11: call XSync before XSetInputFocus during SDL_ShowWindow. This only happens when using a non-NET_WM window manager, as we might try to set the focus before the window is mapped. Fixes #3949.

dbdbae44	2021-04-02T14:35:11	linux: (de)initialize d-bus at init and quit. Previously we had different subsystems quitting it, in conflict, and risked multiple threads racing to init it at the same time. Fixes #3643.
808249a5	2021-01-27T19:40:55	X11: Ungrab the keyboard when the mouse leaves the window GNOME Mutter requires keyboard grab for certain important functionality like window resizing, interaction with the application context menu, and opening the Activites view. To allow Mutter to grab the keyboard as needed, we'll ungrab when the mouse leaves our window. To be safe, we'll do this for all WMs since forks of Mutter and Matacity (and possibly others) may have the same behavior, and we don't want to have to keep track of those.
6b057c67	2021-01-26T19:16:17	Expose separate keyboard and mouse grab support This adds SDL_SetWindowKeyboardGrab(), SDL_GetWindowKeyboardGrab(), SDL_SetWindowMouseGrab(), SDL_GetWindowMouseGrab(), and new SDL_WINDOW_KEYBOARD_GRABBED flag. It also updates the test harness to exercise this functionality and makes a minor fix to X11 that I missed in https://hg.libsdl.org/SDL/rev/02a2d609369b To fit in with this new support, SDL_WINDOW_INPUT_CAPTURE has been renamed to SDL_WINDOW_MOUSE_CAPTURE with the old name remaining as an alias for backwards compatibility with older code.
a0d3c6c6	2021-01-25T21:42:14	Rename SetWindowGrab() to SetWindowMouseGrab()
e1f73e64	2021-01-23T16:22:44	Refactor keyboard grab to be managed by the video core This gives us flexibility to add others hints to control keyboard grab behavior without having to touch all of the backends. It also allows us to possibly expose keyboard grab separately from mouse grab for applications that want to manage those independently.

1ef45c18	2020-11-08T23:40:17	Fixed bug 5339 - Minor memory leak in SDL_x11events.c wcodelyokoyt The atom name that X11_GetAtomName() returns never gets freed, which result in a minor memory leak (14 bytes?) every time the user drops a file on a window. You can see the line in question here: https://github.com/spurious/SDL-mirror/blob/6b6170caf69b4189c9a9d14fca96e97f09bbcc41/src/video/x11/SDL_x11events.c#L1350 Fix: call XFree on name after the while loop.
73010da4	2020-10-19T17:26:33	x11events: ignore UnmapNotify events from XReparentWindow UnmapNotify event does not mean that window has been iconified. It just reports that window changed state from mapped to unmapped. XReparentWindow can unmap and remap window if it was mapped. This causes unnecessary events - HIDDEN, MINIMIZED, RESTORED and SHOW. These events are problematic with Metacity 3.36+ which started to remove window decorations from fullscreen windows. - SDL makes decorated window fullscreen - Metacity removes decorations - SDL gets UnmapNotify and exits from fullscreen - Metacity re-adds decorations As SDL will also get MapNotify event it will try to restore window state causing above steps to repeat. https://bugzilla.libsdl.org/show_bug.cgi?id=5314

9a769da0	2020-09-07T20:10:50	X11: Remove our X11 error callback in X11_DeleteDevice() If we don't remove it, we will infinitely recurse if X11_CreateDevice() is called again and orig_x11_errhandler becomes X11_SafetyNetErrHandler().
8669a87f	2020-07-14T21:13:27	Reuse X11 connection from availability check Instead of creating an X11 connection to test that X11 is available, closing the connection, and then reconnecting for real, use the same connection to handle both cases. The X11 connection retry delay mechanism in the case where X11 is dynamically loaded has been removed. It was only necessary to avoid authetnication token reuse from the XOpenDisplay call that used to exist in X11_Available. Now that this call is only made once, it is no longer needed. Also drop unused and inapplicable code from a comment. ***

eadc8693	2020-05-11T14:31:04	Fixed bug 5103 - Port fcitx support to both fcitx 4 & 5 wengxt Due to the new major fcitx version is coming close, the existing code need to be ported to use new Fcitx dbus interface. The new dbus interface is supported by both fcitx 4 and 5, and has a good side effect, which is that it will work with flatpak for free. Also the patch remove the dependency on fcitx header. Instead, it just hardcodes a few enum value in the code so need to handle the different header for fcitx4 or 5.

d1df3437	2020-02-14T13:17:18	x11: SDL_SetWindowPosition should try to wait for the window manager. Wait up to 100 milliseconds, since the window manager might alter or outright veto the window change...or not respond at all. In a well-functioning system, though, this should help make sure that SDL_SetWindowPosition's results match reality. Fixes Bugzilla #4646.
4b585e75	2020-02-03T08:06:52	Fixed bug 4833 - Use EGL for X11? Martin Fiedler To be precise, this is about desktop OpenGL on X11. For OpenGL ES, EGL is already used (as it's the only way to get an OpenGL ES context), as Sylvain noted above. To shine some light on why this is needed: In 99% of all cases, using GLX on X11 is fine, even though it's effectively deprecated in favor of EGL [1]. However, there's at least one use case that requires the OpenGL context being created with EGL instead of GLX, and that's DRM_PRIME interoperability: The function glEGLImageTargetTexture2DOES simply doesn't work with GLX. (Currently, Mesa actually crashes when trying that.) Some example code: https://gist.github.com/kajott/d1b29c613be30893c855621edd1f212e Runs on Intel and open-source AMD drivers just fine (others unconfirmed), but with #define USE_EGL 0 (i.e. forcing it to GLX), it crashes. The same happens when using SDL for window and context creation. The good news is that most of the pieces for EGL support on X11 are already in place: SDL_egl.c is pretty complete (and used for desktop OpenGL on Wayland, for example), and SDL_x11opengl.c has the aforementioned OpenGL-ES-on-EGL support. However, when it comes to desktop OpenGL, it's hardcoded to fall back to GLX. I'm not advocating to make EGL the default for desktop OpenGL on X11; don't fix what ain't broken. But something like an SDL_HINT_VIDEO_X11_FORCE_EGL would be very appreciated to make use cases like the above work with SDL.

e5af951e	2019-12-02T15:41:25	Fix sending SDL_WINDOWEVENT_RESTORED after unminimizing windows on X11 SDL_SendWindowEvent will only send a RESTORED event if the window has the minimized or maximized flag set. However, for a SHOWN event, it will clear the minimized flag. Since the SHOWN event was being sent first for a MapNotify event, the RESTORED event would never be sent. Swapping the SendWindowEvent calls around fixes this. https://bugzilla.libsdl.org/show_bug.cgi?id=4821
b1539c4c	2019-11-16T22:35:48	Fixed bug 4819 - Attempting to create an OpenGL ES context with unachievable MSAA parameters under X11 dooms the program Solra Bizna I have written a program that, in the event that the user requests more MSAA samples than their hardware supports, attempts to gracefully fall back to the best MSAA available. This code works with my conventional OpenGL renderer, but if I change nothing about the code except to make it request an OpenGL ES profile instead, Xlib kills the program with an error that looks like: X Error of failed request: BadWindow (invalid Window parameter) Major opcode of failed request: 4 (X_DestroyWindow) Resource id in failed request: 0x5c00008 Serial number of failed request: 188 Current serial number in output stream: 193 To trigger the bug, attempt to create a window with the SDL_WINDOW_OPENGL flag, with SDL_GL_CONTEXT_PROFILE_MASK set to SDL_GL_CONTEXT_PROFILE_ES, and with SDL_GL_MULTISAMPLESAMPLES set to any unsupported value. SDL_CreateWindow properly returns NULL, but at this point the program is already doomed. Xlib will shortly terminate the program with an error. Calling SDL_CreateWindow again will immediately trigger this termination. I have attached a skeletal program that reproduces this bug for me. Replacing SDL_GL_CONTEXT_PROFILE_ES with SDL_GL_CONTEXT_PROFILE_COMPATIBILITY avoids the bug (but, obviously, doesn't create an OpenGL ES context). As I suspected, the problem was with XDestroyWindow being called twice on the same window. The X11_CreateWindow function in src/video/x11/SDL_x11window.c calls SetupWindowData. If initialization fails after that point, XDestroyWindow gets called on the window by a subsequent call to X11_DestroyWindow. But, later in the same function, iff a GLES context is requested and initializing it fails, X11_XDestroyWindow (which wraps XDestroyWindow) is manually called. Shortly after, the intended call to X11_DestroyWindow occurs, which attempts to destroy the same window again. Boom. (The above confusing summary involves three separate, similarly-named functions: XDestroyWindow, X11_DestroyWindow, X11_XDestroyWindow) I have attached a simple patch that removes the redundant X11_XDestroyWindow calls. I've tested that XDestroyWindow still gets called for the windows in question, and that it only gets called once.

c0255be4	2019-10-26T23:58:55	x11: check if the X server honored our XMoveWindow() call (thanks, R.E. Rust!). This can happen if a window is still grabbed when we try to move it, or if the X11 ecosystem is just in a bad mood, I guess. This makes sure that SDL will report the correct position for a window; otherwise, SDL_GetWindowPosition will just report whatever the last SDL_SetWindowPosition call requested, even if the window didn't actually move. Fixes Bugzilla #4646.
ed7483f8	2019-10-15T22:36:08	x11: On macOS, look for X11 install in /opt/X11 instead of /usr/X11R6. This is where Apple installs XQuartz now (and apparently, the compatibility symlink at /usr/X11R6 can be missing). Fixes Bugzilla #4706.

8dea23c7	2019-05-19T10:44:14	Fixed bug 3911 - SYSWM generic X11 events missing event data Andrei Drexler For X11 GenericEvents, the associated data is only available between a call to XGetEventData and the matching XFreeEventData, i.e. in X11_HandleGenericEvent. Trying to call XGetEventData a second time on the same event will fail, so an application that wants to inspect XInput2 events (e.g. for stylus pressure) has no way of retrieving its data from queued SYSWM events. The attached patch (based on SDL-2.0.7-11629) sends SYSWM messages from X11_HandleGenericEvent while the data is still available, allowing client code to register an event filter/watcher and process the event inside the callback.

5029d50e	2018-11-10T16:15:48	Add SDL_TouchDeviceType enum and SDL_GetTouchDeviceType(SDL_TouchID id). Touch device types include SDL_TOUCH_DEVICE_DIRECT (a touch screen with window-relative coordinates for touches), SDL_TOUCH_DEVICE_INDIRECT_ABSOLUTE (a trackpad-style device with absolute device coordinates), and SDL_TOUCH_DEVICE_INDIRECT_RELATIVE (a trackpad-style device with screen cursor-relative coordinates). Phone screens are an example of a direct device type. Mac trackpads are the indirect-absolute touch device type. The Apple TV remote is an indirect-relative touch device type.

e061a92d	2018-08-02T16:03:47	Some drag'and'drop improvements. First: disable d'n'd events by default; most apps don't need these at all, and if an app doesn't explicitly handle these, each drop on the window will cause a memory leak if the events are enabled. This follows the guidelines we have for SDL_TEXTINPUT events already. Second: when events are enabled or disabled, signal the video layer, as it might be able to inform the OS, causing UI changes or optimizations (for example, dropping a file icon on a Cocoa app that isn't accepting drops will cause macOS to show a rejection animation instead of the drop operation just vanishing into the ether, X11 might show a different cursor when dragging onto an accepting window, etc). Third: fill in the drop event details in the test library and enable the events in testwm.c for making sure this all works as expected.

Currently the X11 XInput2 backend expects application to do "event.tfinger.x * (window_width-1)" instead. X11 XInput2 touch events are normalized so x is 1.0 at "width - 1" but other SDL backends appear to have x be 1.0 at "width". Same issue for touch event y with regards to height."

c0019b7f	2017-10-11T13:31:21	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.

0782f9be	2017-09-05T08:24:38	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.

f5a38f23	2017-08-21T00:42:06	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)."

a4cfa936	2017-08-14T21:28:04	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).
fb835f9e	2017-08-14T20:22:19	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 src/joystick/linux/SDL_sysjoystick.c -------------------------------------------------------- On Tuesday 24 December 2013 00:43:13 Sven Eckelmann wrote: > I have occasional crashes here caused by the X11 backend of SDL2.

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.
362d5496	2017-08-14T10:28:47	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.

d226594f	2017-08-12T16:48:46	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: DisplayManagerauthName: 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 'DisplayManagerauthName: 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.

This can give some performance boost, and save some resources, as there's no reason to keep a copy of an SDL window's contents on the server: most SDL apps are redrawing completely every frame, and the API allows for expose events to tell an app a redraw is needed anyhow.

X11: Ungrab the keyboard when the mouse leaves the window GNOME Mutter requires keyboard grab for certain important functionality like window resizing, interaction with the application context menu, and opening the Activites view. To allow Mutter to grab the keyboard as needed, we'll ungrab when the mouse leaves our window. To be safe, we'll do this for all WMs since forks of Mutter and Matacity (and possibly others) may have the same behavior, and we don't want to have to keep track of those.

x11events: ignore UnmapNotify events from XReparentWindow UnmapNotify event does not mean that window has been iconified. It just reports that window changed state from mapped to unmapped. XReparentWindow can unmap and remap window if it was mapped. This causes unnecessary events - HIDDEN, MINIMIZED, RESTORED and SHOW. These events are problematic with Metacity 3.36+ which started to remove window decorations from fullscreen windows. - SDL makes decorated window fullscreen - Metacity removes decorations - SDL gets UnmapNotify and exits from fullscreen - Metacity re-adds decorations As SDL will also get MapNotify event it will try to restore window state causing above steps to repeat. https://bugzilla.libsdl.org/show_bug.cgi?id=5314

Fixed bug 4833 - Use EGL for X11? Martin Fiedler To be precise, this is about *desktop OpenGL* on X11. For OpenGL ES, EGL is already used (as it's the only way to get an OpenGL ES context), as Sylvain noted above. To shine some light on why this is needed: In 99% of all cases, using GLX on X11 is fine, even though it's effectively deprecated in favor of EGL [1]. However, there's at least one use case that *requires* the OpenGL context being created with EGL instead of GLX, and that's DRM_PRIME interoperability: The function glEGLImageTargetTexture2DOES simply doesn't work with GLX. (Currently, Mesa actually crashes when trying that.) Some example code: https://gist.github.com/kajott/d1b29c613be30893c855621edd1f212e Runs on Intel and open-source AMD drivers just fine (others unconfirmed), but with #define USE_EGL 0 (i.e. forcing it to GLX), it crashes. The same happens when using SDL for window and context creation. The good news is that most of the pieces for EGL support on X11 are already in place: SDL_egl.c is pretty complete (and used for desktop OpenGL on Wayland, for example), and SDL_x11opengl.c has the aforementioned OpenGL-ES-on-EGL support. However, when it comes to desktop OpenGL, it's hardcoded to fall back to GLX. I'm not advocating to make EGL the default for desktop OpenGL on X11; don't fix what ain't broken. But something like an SDL_HINT_VIDEO_X11_FORCE_EGL would be very appreciated to make use cases like the above work with SDL.

Fixed bug 4819 - Attempting to create an OpenGL ES context with unachievable MSAA parameters under X11 dooms the program Solra Bizna I have written a program that, in the event that the user requests more MSAA samples than their hardware supports, attempts to gracefully fall back to the best MSAA available. This code works with my conventional OpenGL renderer, but if I change nothing about the code except to make it request an OpenGL ES profile instead, Xlib kills the program with an error that looks like: X Error of failed request: BadWindow (invalid Window parameter) Major opcode of failed request: 4 (X_DestroyWindow) Resource id in failed request: 0x5c00008 Serial number of failed request: 188 Current serial number in output stream: 193 To trigger the bug, attempt to create a window with the SDL_WINDOW_OPENGL flag, with SDL_GL_CONTEXT_PROFILE_MASK set to SDL_GL_CONTEXT_PROFILE_ES, and with SDL_GL_MULTISAMPLESAMPLES set to any unsupported value. SDL_CreateWindow properly returns NULL, but at this point the program is already doomed. Xlib will shortly terminate the program with an error. Calling SDL_CreateWindow again will immediately trigger this termination. I have attached a skeletal program that reproduces this bug for me. Replacing SDL_GL_CONTEXT_PROFILE_ES with SDL_GL_CONTEXT_PROFILE_COMPATIBILITY avoids the bug (but, obviously, doesn't create an OpenGL ES context). As I suspected, the problem was with XDestroyWindow being called twice on the same window. The X11_CreateWindow function in src/video/x11/SDL_x11window.c calls SetupWindowData. If initialization fails after that point, XDestroyWindow gets called on the window by a subsequent call to X11_DestroyWindow. But, later in the same function, iff a GLES context is requested and initializing it fails, X11_XDestroyWindow (which wraps XDestroyWindow) is manually called. Shortly after, the intended call to X11_DestroyWindow occurs, which attempts to destroy the same window again. Boom. (The above confusing summary involves three separate, similarly-named functions: XDestroyWindow, X11_DestroyWindow, X11_XDestroyWindow) I have attached a simple patch that removes the redundant X11_XDestroyWindow calls. I've tested that XDestroyWindow still gets called for the windows in question, and that it only gets called once.

This can happen if a window is still grabbed when we try to move it, or if the X11 ecosystem is just in a bad mood, I guess. This makes sure that SDL will report the correct position for a window; otherwise, SDL_GetWindowPosition will just report whatever the last SDL_SetWindowPosition call requested, even if the window didn't actually move.

Fixed bug 3911 - SYSWM generic X11 events missing event data Andrei Drexler For X11 GenericEvents, the associated data is only available between a call to XGetEventData and the matching XFreeEventData, i.e. in X11_HandleGenericEvent. Trying to call XGetEventData a second time on the same event will fail, so an application that wants to inspect XInput2 events (e.g. for stylus pressure) has no way of retrieving its data from queued SYSWM events. The attached patch (based on SDL-2.0.7-11629) sends SYSWM messages from X11_HandleGenericEvent while the data is still available, allowing client code to register an event filter/watcher and process the event inside the callback.

Some drag'and'drop improvements. First: disable d'n'd events by default; most apps don't need these at all, and if an app doesn't explicitly handle these, each drop on the window will cause a memory leak if the events are enabled. This follows the guidelines we have for SDL_TEXTINPUT events already. Second: when events are enabled or disabled, signal the video layer, as it might be able to inform the OS, causing UI changes or optimizations (for example, dropping a file icon on a Cocoa app that isn't accepting drops will cause macOS to show a rejection animation instead of the drop operation just vanishing into the ether, X11 might show a different cursor when dragging onto an accepting window, etc). Third: fill in the drop event details in the test library and enable the events in testwm.c for making sure this all works as expected.

X11 XInput2 touch events are normalized so x is 1.0 at "width - 1" but other SDL backends appear to have x be 1.0 at "width". Same issue for touch event y with regards to height."

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.

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)."

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).

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 src/joystick/linux/SDL_sysjoystick.c -------------------------------------------------------- On Tuesday 24 December 2013 00:43:13 Sven Eckelmann wrote: > I have occasional crashes here caused by the X11 backend of SDL2.

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.

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.
