Brick 7fe6dbaf 2021-07-11T15:25:24 Reset rawInputEnableCount when RawInput is not supported
Hanseul Jun 557d0f82 2021-03-11T13:36:56 Commenting a false alarm in WIN_GLES_SetupWindow. When hint SDL_HINT_OPENGL_ES_DRIVER is set to "1" (e.g. for ANGLE support), assertion due to !_this->gl_config.driver_loaded can be causes while EGL is available.
Dean Herbert 4359a47b 2021-04-02T12:48:16 Simplify ClipCursor behaviour when RelativeMouseMode is enabled The implementation of clip logic for relative mode seemed to unnecessarily limit the usable area to the middle of the window, in a 2x2 pixel region. This has the adverse side effect of moving the operating system cursor to that location, even if it is in a valid location in the window. While in most scenarios this is handled correctly (by storing the original position of the cursor in the window and restoring when leaving relative mode), there are edge cases where this clip operation can cause WM_MOUSEMOVE to fire at a point in time where it counts as a relative delta from SDL's perspective.

Austin Shafer 16e3bfe8 2021-06-28T11:29:16 SetDisplayMode: Call XRRSetScreenSize before setting CRTC config X11_SetDisplayMode currently calls X11_XRRSetCrtcConfig alone. This results in the monitor's viewport getting changed, but the underlying screen dimensions stay the same. The spec indicates that RRSetCrtcConfig only changes the crtc mode and has no effect on the screen dimensions, only mentioning that the new crtc must fit entirely within the screen size. For the size to change, RRSetScreenSize also needs to be called. This affects Metro Exodus on Linux, when changing the resolution in the in-game settings Metro gets stuck in a loop waiting for the size of its vulkan surface to change. Because XRRSetScreenSize is not called the screen size is never changed, the vulkan surface dimensions do not change, and Metro hangs forever watching for a surface size update that will never come. This change disables the CRTC, calls XRRSetScreenSize, and then updates the CRTC configuration. This fixes changing the resolution from the Metro settings. Tested with: Metro Exodus, Portal 2

Ozkan Sezer bc9888c9 2021-06-12T14:55:24 OS2_GetDisplayModes: malloc a new copy of mode's driver data. Based on a patch by Jochen Schäfer <josch1710@live.de> : The problem is, that in the initialization code uses the same structure for desktop_mode and current_mode. See SDL_os2video.c:OS2_VideoInit(): stSDLDisplay.desktop_mode = stSDLDisplayMode; stSDLDisplay.current_mode = stSDLDisplayMode; ... stSDLDisplayMode.driverdata = pDisplayData; Then, if you call GetDisplayModes, current_mode will added to the modes list, with the same driverdata pointer to desktop_mode. SDL_AddDisplayMode( display, &display->current_mode ); When VideoQuit gets called, first the modes list gets freed including the driverdata, the desktop_mode gets freed. See SDL_video.c:SDL_VideoQuit(): for (j = display->num_display_modes; j--;) { SDL_free(display->display_modes[j].driverdata); display->display_modes[j].driverdata = NULL; } SDL_free(display->display_modes); display->display_modes = NULL; SDL_free(display->desktop_mode.driverdata); display->desktop_mode.driverdata = NULL; So, the display_modes[j].driverdata gets freed, but desktop_mode->driverdata points to the same memory, but is not NULL'ed. When desktop_mode->driverdata gets freed the memory is already freed, and libcx crashes the application on SDL_Quit.

Cameron Gutman e13b43ac 2021-06-05T12:44:08 Don't skip sending wakeups for the current thread We can be in a situation where we receive a win32 hook callback on the same thread that is currently waiting. In that case, we do still need to trigger a wakeup when an event is pushed because the hook itself won't necessarily do that (depending on what we return from the hook).
Cameron Gutman 85b51e6c 2021-06-05T11:46:47 Fall back to polling normally if not operating the win32 message loop In this condition, we cannot safely wait/wake on events.

Jupeyy 64724db0 2021-06-04T19:55:30 Implement bare minimum for SDL_FlashWindow
Francesco Abbate 0dd7024d 2021-03-12T21:58:20 Modifies WaitEvent and WaitEventTimeout to actually wait instead of polling When possible use native os functions to make a blocking call waiting for an incoming event. Previous behavior was to continuously poll the event queue with a small delay between each poll. The blocking call uses a new optional video driver event, WaitEventTimeout, if available. It is called only if an window already shown is available. If present the window is designated using the variable wakeup_window to receive a wakeup event if needed. The WaitEventTimeout function accept a timeout parameter. If positive the call will wait for an event or return if the timeout expired without any event. If the timeout is zero it will implement a polling behavior. If the timeout is negative the function will block indefinetely waiting for an event. To let the main thread sees events sent form a different thread a "wake-up" signal is sent to the main thread if the main thread is in a blocking state. The wake-up event is sent to the designated wakeup_window if present. The wake-up event is sent only if the PushEvent call is coming from a different thread. Before sending the wake-up event the ID of the thread making the blocking call is saved using the variable blocking_thread_id and it is compared to the current thread's id to decide if the wake-up event should be sent. Two new optional video device methods are introduced: WaitEventTimeout SendWakeupEvent in addition the mutex wakeup_lock which is defined and initialized but only for the drivers supporting the methods above. If the methods are not present the system behaves as previously performing a periodic polling of the events queue. The blocking call is disabled if a joystick or sensor is detected and falls back to previous behavior.

Anthony Pesch fc508eab 2021-05-23T15:59:20 kmsdrm: remove redundant modeset_pending flag this variable was added in commit 2067a7db8e4a36ba40ab34a55b3166ca28638a60 and ultimately tracks if this is a surface's first present. checking if the current bo is NULL provides the same functionality and cuts down on a redundant piece of state potentially getting out of sync in the future
Anthony Pesch 4c965b7a 2021-05-23T16:09:27 kmsdrm: fix SetDisplayMode binding the the wrong surface / context SetDisplayMode needs to recreate the EGL surfaces, which then need to be bound along with the correct context in each rendering thread commit 3a1d7d9c9ac670bf35cfa8ebf3706a1e2a3e5de4 removed this behavior which has broken using SetDisplayMode when rendering with multiple contexts the commit message was rather vague, but if the surfaces do need to be created immediately, this process probably needs to be split such that surface is created immediately, but the binding is deferred
Anthony Pesch 0219928d 2021-05-23T16:06:40 kmsdrm: honor mode previously set by SDL_SetWindowDisplayMode when enabling fullscreen and remove duplicate SDL_WINDOWEVENT_RESIZED event commit 2067a7db8e4a36ba40ab34a55b3166ca28638a60 made SDL_SetWindowSize and SDL_SetWindowFullscreen modify the display mode previously set by a call to SDL_SetWindowDisplayMode as far as I understand the SDL API, calling SDL_SetWindowDisplayMode followed by calling SDL_SetWindowFullscreen(..., SDL_WINDOW_FULLSCREEN) is the correct way to mode set / switch to fullscreen this change restores that functionaliy when switching to SDL_WINDOW_FULLSCREEN, but other cases are still modifying the display mode set by the user. rather than modifying the display mode set by the user, it seems this logic inside of KMSDRM_ReconfigureWindow should be pushed further down into KMSDRM_CreateSurfaces (as it was originally) to only modify the final mode that's set (based on the fullscreen flags), but not override the mode requested by the user
Anthony Pesch fd5de93a 2021-05-23T16:05:39 kmsdrm: fix gbm surface dimensions not matching the mode being set commit 2067a7db8e4a36ba40ab34a55b3166ca28638a60 introduced new surface_w and surface_h variables which were passed to gbm_surface_create rather than the dimensions from the drmModeModeInfo structure. commit 5105ecf8b1b37ab4e4b8344550c90dd69f49909e further refactored this code and no longer synchronized these variables inside KMSDRM_SetDisplayMode, breaking it this change removes the variables since they're seemingly redundant to begin with
Ryan C. Gordon fed84650 2021-05-27T10:40:41 loadbmp: Attempt to handle small palettes better. Only adjust the biClrUsed field if it is set to zero in the bitmap, and make some effort to make sure we don't overflow a buffer in any case. This was triggering an issue with the sailboat bmp used for testpalette.c in SDL 1.2, which is an 8-bit paletted image with 66 palette entries instead of 256. See discussion at https://github.com/libsdl-org/sdl12-compat/issues/63 This change might be a problem, but there's no indication this code, which originally landed in SDL_image 17 years ago with a large rewrite, is actually fixing a specific issue. I'm also not sure we should actually make an effort to accept a bmp that has a biClrUsed field that is both non-zero and _also_ incorrect.
Sam Lantinga 157c3f80 2021-05-21T09:45:08 [SDL] Minimize number of system calls when handling WM_INPUT raw input messages. Details: Currently doing 4 system calls per WM_INPUT message, which can cause the thread handling the message loop to be swapped out several times: * GetProp - to get window data from the window handle * GetRawInputData - to retrieve the raw input data * 2 calls to GetMessageExtraInfo - to ignore synthetic mouse events generated for touchscreens In this change: * Replaced GetProp by iterating the list of windows maintained by SDL (with a fallback to GetProp). Note that this will affect all messages and not just WM_INPUT * only calling GetMessageExtraInfo if a touchscreen has been detected Fix for https://jira.valve.org/browse/CSGO-4855 @saml

Ethan Lee 9161f951 2021-04-27T02:25:57 egl: Reject attempts to set negative swap intervals
Ryan C. Gordon c54c16d3 2021-04-30T13:19:36 wayland: don't hang in SDL_GL_SwapBuffers if the compositor is ghosting us. If you hide a window on Mutter, for example, the compositor never requests new frames, which will cause Mesa to block forever in eglSwapBuffers to satisfy the swap interval. We now always set the swap interval to 0 and manage this ourselves, handing the frame to Wayland when it requests a new one, and timing out at 10fps just to keep apps moving if the compositor wants no frames at all. My understanding is that other protocols are coming that might improve upon this solution, but for now it solves the total hang. Fixes #4335.

Ryan C. Gordon 8527c583 2021-04-27T01:36:23 cocoa: Fix recreated windows that are both borderless and resizable. These would accidentally get a titlebar because the "borderless" style mask is zero but the resizable attribute adds a bit. I assume this happens because you used to need window decoration to resize a window in macOS, but this changed in later releases. This only caused problems when recreating a window (you had an SDL_WINDOW_OPENGL window and tried to create a Metal SDL_Renderer on it, etc). Fixes #4324.
Ryan C. Gordon 2fdbae22 2021-04-26T18:43:28 cocoa: Remove mouse event tap. It doesn't appear to work anymore, and was disabled by default anyhow, since the needed APIs are forbidden on the Mac App Store. A better solution to lock the mouse to the window on macOS would still be welcome. CGAssociateMouseAndMouseCursorPosition() works fine for relative mouse mode, this was just a question of SDL_SetWindowGrab(). As it stands now, a grabbed mouse can briefly break out of the window, causing varying degrees of chaos.
Ryan C. Gordon 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.
Ryan C. Gordon 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.

Sylvain 6be9c009 2021-04-20T13:46:25 Android: prevent error EGL_BAD_DISPLAY while getting egl version without display There is an error "E libEGL : validate_display:91 error 3008 (EGL_BAD_DISPLAY)" that occurs when calling "eglQueryString(display, EGL_VERSION)", with EGL_NO_DISPLAY. Khronos says "EGL_BAD_DISPLAY is generated if display is not an EGL display connection, unless display is EGL_NO_DISPLAY and name is EGL_EXTENSIONS." but this was added in SDL with "EGL 1.5 allows querying for client version" ( https://github.com/libsdl-org/SDL/commit/56363ebf6124b345e1cfbd14fb6c0e654837910c ) In fact: - it actually doesn't work on Android that has 1.5 egl client - it works on desktop X11 (using SDL_VIDEO_X11_FORCE_EGL=1) The commit moves the version call where it's used, eg inside the "if (platform) {" and checks that "eglGetPlatformDisplay" has been correctly loaded.

Ethan Lee ed24c345 2021-04-16T21:35:50 wayland: Implement basic window move events via wl_surface_listener. This unearthed an unspeakably large amount of bugs in the wl_output enumerator, notably the fact that the wl_output user pointer was to temporary memory! This was "fixed" in e862856, and was then pointed out as a leak in 4183211, which was undone in d9ba204. The busted fix was correct that the malloc was an issue, but wrong about _why_; SDL_AddVideoDisplay copies by value and does not reuse the pointer, so generally you want your VideoDisplay to be on the stack, but of course the callbacks don't allow that, so a malloc was a workaround. But we can do better and just host our temporary display inside WaylandOutputData because that will be persistent while also not leaking. Wait, wasn't I talking about move events? Right, that: wl_surface_listener does at least give us the ability to know what monitor we're on, even though we have no idea where we are on the monitor. All we need to do is check the wl_output against the display list and then push a move event that both indicates the correct display while also not being _too_ much of a lie (but enough of a lie to where our event doesn't get discarded as "undefined" or whatever). The index check for the video display is what spawned the great nightmare you see before you; aside from the bugfix this is actually a really basic patch.

This is to be consistent with previous behavior that would only register the handler in -[SDLAppDelegate applicationDidFinishLaunching:] and allows the running app to opt out of the behavior by setting its own app delegate. - The URL event handler is now removed if it was set on SDLAppDelegate dealloc
