Ethan Lee ae67c7d2 2021-11-09T01:30:00 Implemented SDL_SetWindowMouseRect() on Wayland
Cameron Gutman 2bf36bfa 2021-10-24T21:28:04 wayland: Implement WaitEventTimeout() and SendWakeupEvent() We can have spurious wakeups in WaitEventTimeout() due to Wayland events that don't end up causing us to generate an SDL event. Fortunately for us, SDL_WaitEventTimeout_Device() handles this situation properly by calling WaitEventTimeout() again with an adjusted timeout.
Cameron Gutman 408a93a1 2021-10-23T15:43:04 wayland: Use multi-thread event reading APIs Wayland provides the prepare_read()/read_events() family of APIs for reading from the display fd in a deadlock-free manner across multiple threads in a multi-threaded application. Let's use those instead of trying to roll our own solution using a mutex. This fixes an issue where a call to SDL_GL_SwapWindow() doesn't swap buffers if it happens to collide with SDL_PumpEvents() in the main thread. It also allows coexistence with other code or toolkits in our process that may want read and dispatch events themselves.
David Gow 25f9e32b 2021-10-02T16:52:43 wayland: Don't let multiple threads dispatch wayland events at once wl_display_dispatch() will block if there are no events available, and while we try to avoid this by using SDL_IOReady() to verify there are events before calling it, there is a race condition between SDL_IOReady() and wl_display_dispatch() if multiple threads are involved. This is made more likely by the fact that SDL_GL_SwapWindow() calls wl_display_dispatch() if vsync is enabled, in order to wait for frame events. Therefore any program which pumps events on a different thread from SDL_GL_SwapWindow() could end up blocking in one or other of them until another event arrives. This change fixes this by wrapping wl_display_dispatch() in a new mutex, which ensures only one thread can compete for wayland events at a time, and hence the SDL_IOReady() check should successfully prevent either from blocking.

meyraud705 4ada14a2 2021-07-21T13:39:10 Replace libc functions to SDL equivalent in wayland video subsystem Wayland video subsystem uses a mix of libc and SDL function. This patch switches libc functions to SDL ones and fixes a mismatch in memory allocation/dealoccation of SDL_Cursor in SDL_waylandmouse.c (calloc on line 201 and SDL_free on line 313) which caused memory corruption if custom memory allocator where provided to SDL.

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.
Ethan Lee f88d91d5 2021-04-12T23:47:23 wayland: Minor whitespace fix
Ethan Lee d785dab5 2021-04-12T23:37:53 wayland: Add unscaled resolutions to the display mode list
Ethan Lee 7510245a 2021-04-08T14:08:35 wayland: Create the data_device only after both device_manager and input exist. There is no guarantee on what order the Wayland interfaces will come in, but the callbacks were assuming that wl_data_device_manager would could before wl_seat. This would cause certain desktops to not have any data_device to work with, meaning certain features like the clipboard would silently no-op.
David Edmundson 6fd37194 2021-04-07T16:03:41 wayland: Fix leaked zxdg_decoration_manager
David Edmundson f6a09ef1 2021-04-07T16:16:23 wayland: Drop support for kwin specific decoration management KWin has supported the shared and formalised zxdg_decoration since Plasma 5.16 which came out mid 2019. Whilst it made sense to support them both for a while, it should not be needed for future SDL releases.
Ryan C. Gordon 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.
Ethan Lee eeee7308 2021-03-29T16:57:03 wayland: Implement IME support. Note that this is purely to make it possible to enter text that requires composition - for example, before this commit Kanji input didn't work at all. The big problem this still has is that we need the window position, and this is still not implemented. Once we have this information we can do the equivalent of XTranslateCoordinates to put the rectangle where we want it.
Ethan Lee 57a927e8 2021-02-12T14:27:58 wayland: Explicitly set min/max size for xdg-shell

Cameron Gutman a0d3c6c6 2021-01-25T21:42:14 Rename SetWindowGrab() to SetWindowMouseGrab()
Cameron Gutman 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.
Ethan Lee e787282b 2021-01-23T15:40:22 Implement Wayland_SetWindowResizable
Cameron Gutman bd553ea8 2021-01-20T21:17:20 Implement support for inhibiting the screensaver on Wayland We support both the org.freedesktop.ScreenSaver D-Bus API (same as the X11 backend) and the Wayland idle_inhibit_unstable_v1 protocol. Some Wayland compositors only support one or the other, so we need both to for broad compatibility.
Cameron Gutman 19236b46 2021-01-21T21:49:13 Implement support for minimizing windows on Wayland This required a bit of extra code to deal with the transition from minimized back to fullscreen
Cameron Gutman d789ba83 2021-01-19T18:20:07 Implement keyboard grab support for Wayland Use zwp_keyboard_shortcuts_inhibit_manager_v1 to allow SDL applications to capture system keyboard shortcuts like Alt+Tab when keyboard grab is enabled via SDL_HINT_GRAB_KEYBOARD.

M Stoeckl a78b9763 2020-07-14T19:18:16 Reuse Wayland connection from availability check
M Stoeckl 052a1373 2020-07-12T19:11:15 Merge VideoBootStrap::available into VideoBootStrap::create The two are only ever called together, and combining them makes it possible to eliminate redundant symbol loading and redundant attempts to connect to a display server.
Tudor Brindus 1a291ab1 2020-04-17T13:55:44 wayland: add support for SDL_SetWindowGrab

Michael Forney cdbeae52 2019-12-29T23:10:39 wayland: support wl_data_device_manager version < 3
Sam Lantinga afdb40af 2019-08-05T23:38:48 Fixed bug 4689 - SDL fails to detect compositor shutdown on Wayland -- program keeps running M Stoeckl To reproduce: 1. Run any SDL-based program with a Wayland compositor, orphaning it so that it doesn't have an immediate parent process. (For example, from a terminal, running `supertux2 & disown`.) The program should use the wayland backend, i.e. by setting environment variable SDL_VIDEODRIVER=wayland. 2. Kill the compositor process. Results: - The SDL program will keep running. Expected results: - The SDL program should close. (What close should mean here, I'm not sure - is injecting an SDL_Quit the appropriate action when a video driver disconnects?) Build data: 2019-06-22, hg tip (12901:bf8d9d29cbf1), Linux, can reproduce with sway, weston, and other Wayland oompositors.

Sam Lantinga 5febdfce 2018-09-24T11:49:25 Fixed whitespace
Ryan C. Gordon c8ac9096 2018-06-24T22:42:36 wayland: Implemented xdg-wm-base support. This is just in parity with the existing zxdg-shell-unstable-v6 code. Making the Wayland target robust (and uh, with title bars) is going to take a lot of work on top of this.
Ryan C. Gordon cd532207 2018-02-07T13:13:55 wayland: Add support for xdg-shell protocol (unstable v6). This is meant to be the desktop-enhanced version of wl_shell. Right now we just match what the existing wl_shell code does, but there are other areas of functionality available to us now, that we can fill in later. This uses the "unstable" API, since this is what ships in Ubuntu 17.10 (as part of Wayland 1.10), but Wayland 1.12 promotes this to stable with extremely minor changes. We will add support for the stable version when it makes sense to do so.
Sam Lantinga 8111a632 2018-01-03T10:49:26 Fixed bug 4013 - Wayland: fix videoquit on multimonitor system Vladimir On multimonitor system Wayland_VideoQuit invalid deiniting. Tested in Centos7 + Weston

Philipp Wiesemann 6c0aea42 2017-05-25T23:00:58 wayland: Fixed freeing memory of SDL_malloc() with plain free().
Sam Lantinga d3591800 2017-01-03T00:44:05 Fixed bug 3519 - SDL_GetDisplayMode fails to report mode.format when using Wayland backend Ryan C. Gordon Kristian says you can't do it with Wayland, and that going forward, it'll just handle whatever you throw at it anyhow. https://twitter.com/hoegsberg/status/816148272402165761 So I say we mark it SDL_PIXELFORMAT_RGB888, which is what my X11 display currently reports, and leave it at that.

Sam Lantinga d767a450 2016-11-06T08:34:27 Fixed 2942 - Wayland: Drag and Drop / Clipboard x414e54 I have implemented Drag and Drop and Clipboard support for Wayland. Drag and dropping files from nautilus to the testdropfile application seems to work and also copy and paste.
Sam Lantinga 063f752e 2016-10-13T04:54:43 Fixed bug 3328 - Race condition in Wayland_VideoInit Robert Folland When running this little test program with SDL2 on Wayland it often crashes in SDL_Init. From a backtrace it is apparent that there is a race condition in creating a xkb_context_ref. Sometimes it is 0x0. By moving the relevant lines higher up in Wayland_VideoInit (in SDL2-2.0.4/src/video/wayland/SDL_waylandvideo.c:302) this seems to get fixed. I moved the call to WAYLAND_xkb_context_new() up to before the call to WAYLAND_wl_display_connect(). Here is the test program (just a loop of init and quit), and a backtrace from gdb: #include <cstdio> #include <stdlib.h> #include <SDL2/SDL.h> #include <unistd.h> #include <iostream> int main(int argc, char **argv) { int count = atoi(argv[1]); for (int i = 0; i < count; i++) { std::cout << "Init " << i << std::endl; if (SDL_Init(SDL_INIT_VIDEO) < 0) { SDL_LogError(SDL_LOG_CATEGORY_APPLICATION, "Couldn't initialize SDL: %s\n", SDL_GetError()); return 1; } std::cout << "Quit" << std::endl; SDL_Quit(); } return 0; } Init 12 Quit Init 13 Program received signal SIGSEGV, Segmentation fault. xkb_context_ref (ctx=ctx@entry=0x0) at src/context.c:156 156 ctx->refcnt++; (gdb) bt #0 xkb_context_ref (ctx=ctx@entry=0x0) at src/context.c:156 #1 0x00007ffff5e1cd4c in xkb_keymap_new (ctx=0x0, format=XKB_KEYMAP_FORMAT_TEXT_V1, flags=flags@entry=XKB_KEYMAP_COMPILE_NO_FLAGS) at src/keymap-priv.c:65 #2 0x00007ffff5e1c6cc in xkb_keymap_new_from_buffer (ctx=<optimized out>, buffer=0x7ffff7fd5000 "xkb_keymap {\nxkb_keycodes \"(unnamed)\" {\n\tminimum = 8;\n\tmaximum = 255;\n\t<ESC>", ' ' <repeats 16 times>, "= 9;\n\t<AE01>", ' ' <re peats 15 times>, "= 10;\n\t<AE02>", ' ' <repeats 15 times>, "= 11;\n\t<AE03>", ' ' <repeats 15 times>, "= 12;\n\t<AE04>", ' ' <repeats 12 times>..., length=48090, format=<optimized out>, flags=<optimized out>) at src/keymap.c:191 #3 0x00007ffff7b8ea4e in keyboard_handle_keymap (data=0x6169b0, keyboard=<optimized out>, format=<optimized out>, fd=5, size=48091) at /home/vlab/abs/sdl2/src/SDL2-2.0.4/src/video/wayland/SDL_waylandevents.c:269 #4 0x00007ffff64501f0 in ffi_call_unix64 () from /usr/lib/libffi.so.6 #5 0x00007ffff644fc58 in ffi_call () from /usr/lib/libffi.so.6 #6 0x00007ffff665be3e in wl_closure_invoke (closure=closure@entry=0x61f000, flags=flags@entry=1, target=<optimized out>, target@entry=0x616d20, opcode=opcode@entry=0, data=<optimized out>) at src/connection.c:949 #7 0x00007ffff6658be0 in dispatch_event (display=<optimized out>, queue=<optimized out>) at src/wayland-client.c:1274 #8 0x00007ffff6659db4 in dispatch_queue (queue=0x617398, display=0x6172d0) at src/wayland-client.c:1420 #9 wl_display_dispatch_queue_pending (display=0x6172d0, queue=0x617398) at src/wayland-client.c:1662 #10 0x00007ffff665a0cf in wl_display_roundtrip_queue (display=0x6172d0, queue=0x617398) at src/wayland-client.c:1085 #11 0x00007ffff7b8faa0 in Wayland_VideoInit (_this=<optimized out>) at /home/vlab/abs/sdl2/src/SDL2-2.0.4/src/video/wayland/SDL_waylandvideo.c:302 #12 0x00007ffff7b7aed6 in SDL_VideoInit_REAL (driver_name=<optimized out>, driver_name@entry=0x0) at /home/vlab/abs/sdl2/src/SDL2-2.0.4/src/video/SDL_video.c:513 #13 0x00007ffff7ae0ee7 in SDL_InitSubSystem_REAL (flags=16416) at /home/vlab/abs/sdl2/src/SDL2-2.0.4/src/SDL.c:173 #14 0x0000000000400b24 in main (argc=2, argv=0x7fffffffebb8) at vplay-init.cpp:13 (gdb)
Sam Lantinga eea76fc1 2016-10-07T18:11:03 Fixed bug 3063 - Wayland: SDL resizes EGL surface to 0x0. x414e54 Wayland will sometimes send empty resize events (0 width and 0 height) to the client. I have not worked out the exact conditions a client would receive these but I can assume it might be if the window is offscreen or not mapped yet. This causes issues with some SDL clients as they receive the 0x0 event and unexpected resize event or might not request to resize back to the correct size. As per the wl_shell Wayland spec configure events are only a suggestion and the client is free to ignore or pick a different size (this is how min/max and fixed aspect ratio is supped to be implemented). A patch is attached but is just the first iteration and I will fix any issues such as checking for FULLSCREEN/MAXIMIZED or RESIZABLE flags unless someone else fixes this first. I have update to take into account non resizable and fullscreen windows. Also adding in maximize/restore and title functions for Wayland.
Sam Lantinga f11a4409 2016-09-01T01:26:56 wayland: Add support for relative mouse mode, by Jonas ?dahl <jadahl@gmail.com> Generate the C protocol files from the protocol XML files installed by wayland-protocols, and use them to implement support for relative pointer motions and pointer locking. Note that at the time, the protocol is unstable and may change in the future. Any future breaking changes will, however, fail gracefully and result in no regressions compared to before this patch.
Bastien Nocera 736a624d 2016-09-01T01:22:58 Wayland: Set "class" for each window we create This will be used by Wayland compositors to match the application ID and .desktop file to the SDL window(s). Applications can set the SDL_VIDEO_WAYLAND_WMCLASS environemnt variable early in the process to override using the binary name as a fallback. Note that we also support the SDL_VIDEO_X11_WMCLASS in the Wayland backend so that if a program correctly associated the desktop file with the window under X11, only a newer SDL would be needed for it to work under Wayland. https://bugzilla.libsdl.org/show_bug.cgi?id=3376

Philipp Wiesemann 0e45984f 2015-06-21T17:33:46 Fixed crash if initialization of EGL failed but was tried again later. The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly uninitialized data structure if loading the library first failed. A later try to use EGL then skipped initialization and assumed it was previously successful because the data structure now already existed. This led to at least one crash in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was dereferenced to make a call to eglBindAPI().

Edward Rudd b88ca1b4 2015-02-10T16:28:56 the last parameter of XChangeProperty is the number of elements.. and when the element format is 32.. the element is "long" so we have 5 long elements here. Yes this seems confusing as on mac+linux Long is either 32 or 64bits depending on the architecture, but this is how the X11 protocol is defined. Thus 5 is the correct value for the nelts here. Not 5 or 10 depending on the architecture. More info on the confusion https://bugs.freedesktop.org/show_bug.cgi?id=16802
