2021-02-15xwayland/selection: log when proxy window loses ownershipTudor Brindus
2021-02-15xwayland/selection: ignore requests for anything but the newest dataTudor Brindus
Our internal state machine gets screwed up if selection events are not monotonically increasing in time, and we can enter a self-copy loop from the proxy window that exhausts all pipes. Snippet of logs when this occurs: 00:00:46.238 [wlr] [xwayland/selection/incoming.c:487] XCB_XFIXES_SELECTION_NOTIFY (selection=277, owner=4194626) 00:00:46.238 [wlr] [xwayland/selection/incoming.c:487] XCB_XFIXES_SELECTION_NOTIFY (selection=277, owner=2097153) 00:00:46.238 [wlr] [xwayland/selection/outgoing.c:378] XCB_SELECTION_REQUEST (time=58979563 owner=2097153, requestor=2097153 selection=277, target=279, property=278) 00:00:46.238 [wlr] [xwayland/selection/outgoing.c:397] ignoring old request from timestamp 58979563; expecting > 58979563 00:00:46.238 [wlr] [xwayland/selection/outgoing.c:29] SendEvent destination=2097153 SelectionNotify(31) time=58979563 requestor=2097153 selection=277 target=279 property=0 00:00:46.238 [wlr] [xwayland/selection/incoming.c:453] XCB_SELECTION_NOTIFY (selection=277, property=0, target=279) Note that 2097153 is `selection->window`, and 4194626 is Emacs. The race occurs if the selection owner changes back to our proxy window between when we get `XCB_XFIXES_SELECTION_NOTIFY` for Emacs and when we call `xcb_convert_selection` in `incoming.c:source_send` -- the ConvertSelection request can end up hitting our proxy window, but the timestamp will be rejected. Fixes #2192.
2021-02-14examples: remove wlroots dep from client examplesSimon Ser
There is one exception: layer-shell still uses wlr_log. Would need to convert to fprintf to drop the wlroots dep there. Fixes: 34e7f69d6942 ("examples: remove dependency on wlr_egl from clients")
2021-02-14examples: drop wlr/render/egl.h include from client examplesSimon Ser
We use egl_common.h instead. Fixes: 34e7f69d6942 ("examples: remove dependency on wlr_egl from clients")
2021-02-14examples: drop wlroots dep from egl_common.cSimon Ser
Just use fprintf instead of wlr_log.
2021-02-08xdg-foreign: rename finish_* functions to destroy_*Tadeo Kondrak
They free their argument, so the name is more clear.
2021-02-08xdg-foreign: Make imported object inert when exported is destroyedTadeo Kondrak
Fixes a double-free experienced with Firefox and xdg-desktop-portal-gtk.

2021-02-08backend/x11: drop x11-xcb dependencySimon Ser
We don't need it anymore now that we've stopped using the EGL Xlib platform.
2021-02-07tablet_v2: Fix implicit grab end detectionJustus Rossmeier
Store the previously focused surface in `state->focused` as well as in `state->original` when starting an implicit grab. That way at the end of an implicit grab, the detection whether the grab started and ended on the same surface works as intended, even if the original surface was never left at all.
2021-02-06region: remove leftover description of resource_listBrandon Dowdy
"resource_list" no longer exists for regions. Remove the last remaining description of what it does.
2021-02-05render/gles2: remove YUV blocklistSimon Ser
Mesa provides YUV shaders, and can import multi-planar YUV DMA-BUFs as a single EGLImage. Remove the arbitrary limitation. If the driver doesn't support importing YUV as a single EGLImage, the import will fail and the result will be the same anyways.

Fixes #2659
2021-02-05xwayland: free render picture backing cursorIlia Mirkin
Otherwise it gets leaked never to be recovered.

This requires a change to the type of `struct wlr_tablet` and `wlr_tablet_init` signature, both of which are part of the unstable API.

2021-02-04xwayland/selection: allow simultaneous Wayland-to-X11 transfersTudor Brindus
There seems to be no reason why we can't service multiple Wayland-to-X11 transfers concurrently, so long as they are to different windows (or possibly, same windows but different target properties?) This commit removes the queuing logic, but retains the request de-duplication from #2428.
2021-02-04xwayland/selection: use one target window per selectionTudor Brindus
Previously, the clipboard and primary selections shared the same window. This was racey, and could have led to pasting failures. On xfixes selection owner change notification, the logic for requesting the supported mimetypes of the new owner's selection looks like: xcb_convert_selection( xwm->xcb_conn, selection->window, selection->atom, xwm->atoms[TARGETS], xwm->atoms[WL_SELECTION], selection->timestamp ); This means ask the selection owner to write its TARGETS for the `selection->atom` selection (one of PRIMARY, CLIPBOARD, DND_SELECTION) to `selection->window`'s WL_SELECTION atom. However, `selection->window` is shared for both PRIMARY and CLIPBOARD selections, and WL_SELECTION is used as the target atom in both cases. So, there's a race when both selections change at the same time. The CLIPBOARD selection might support mimetypes {A, B, C}, and the PRIMARY only {A, B}. If the ConvertSelection requests/responses "cross on the wire", so to speak, wlroots can end up believing that the PRIMARY selection also supports C. A Wayland client may then ask for the PRIMARY selection in C format, which will fail with "convert selection failed". This commit fixes this by using a separate window for PRIMARY and CLIPBOARD target requests, so that WL_SELECTION can be used as the target atom in both cases.
2021-02-04xwayland/selection: use one X11 window per incoming transferTudor Brindus
This commit introduces logic for using a new X11 window for each incoming transfer, rather than having a global window for each selection source. This eliminates a whole class of bugs involving multiple concurrent incoming transfers. For now, we retain the outgoing transfer queue, and the selection source-specific windows to support it. Source-specific windows are no longer used in the incoming path, and will be removed in a future PR. Refs #1497.
2021-02-04examples/egl_common: make attribs constBrandon Dowdy
Make (config, context)_attribs const just to be on the safe side.
2021-02-03backend/wayland: flush remote displaySimon Ser
It turns out wl_event_source_check is not enough to guarantee that the remote wl_display will be flushed after we queue requests. We need to explicitly flush, just like we do in our X11 code. References: https://gitlab.freedesktop.org/wayland/wayland/-/issues/187
2021-02-02region: remove resource_list arg from region_createSimon Ser
This is never used.
2021-02-02region: make wlr_region_create privateSimon Ser
This function should only be called from the handler for wl_compositor.create_region requests.
2021-02-02render/dmabuf: make src arg const in wlr_dmabuf_attributes_copySimon Ser

2021-02-01render/wlr_texture: clamp texture coordinates to edge by defaultQuantum
Clamping texture coordinates prevents OpenGL from blending the left and right edge (or top and bottom edge) when scaling textures with GL_LINEAR filtering. This prevents visual artifacts like swaywm/sway#5809. Per discussion on IRC, this behaviour is made default. Compositors that want the wrapping behaviour (e.g. for tiled patterns) can override this by doing: struct wlr_gles2_texture_attribs attribs; wlr_gles2_texture_get_attribs(texture, &attribs); glBindTexture(attribs.target, attribs.tex); glTexParameteri(attribs.target, GL_TEXTURE_WRAP_S, GL_REPEAT); glTexParameteri(attribs.target, GL_TEXTURE_WRAP_T, GL_REPEAT); glBindTexture(attribs.target, 0);
2021-02-01render/egl: log whether DMA-BUF modifiers are supportedSimon Ser
2021-02-01render/egl: add check for EGL_KHR_surfaceless_contextBrandon Dowdy
As surfaces are no longer going to be used for wlr_egl, I may as well just go and add this check as it is needed for safety whenever surface-less rendering is being used.
2021-01-31xwayland/selection: make xwm_selection_init take a wlr_xwm_selection *Tudor Brindus
This makes it consistent with xwm_selection_finish.
2021-01-31xwayland/selection: introduce `xwm_selection_transfer_init`Tudor Brindus
Currently, all this does is initialize `wl_client_fd` to -1, so that comparisons with 0 are meaningful.
2021-01-31xwayland/selection: make xwm_selection_finish take a wlr_xwm_selection *Tudor Brindus
Previously it took a wlr_xwm *, which was a bit surprising in that it freed members of wlr_xwm *, not just its respective selections.
2021-01-31xwayland/selection: destroy all selections on Xwayland restartTudor Brindus
Previously, Xwayland could restart, and we'd get events for transfers pointing to the previous (now freed) xwm instance. This led to use-after-free segfaults. Closes #2565.
2021-01-31xwayland/selection: don't leak Wayland fd if ConvertSelection failsTudor Brindus
If our ConvertSelection failed, we would previously leak the pending Wayland client fd. Refs swaywm/sway#5946.
2021-01-31xwayland/selection: don't request another selection while one is pendingTudor Brindus
This will hopefully be fixed in the future by having separate windows for each X11-to-Wayland transfer, but until then, let's avoid a compositor crash.
2021-01-30examples: remove "major" and "minor" from egl_common.cBrandon Dowdy
Remove "major" and "minor" from egl_common.c as they are not used by the examples that use egl_common.c.
2021-01-29backend/wayland: remove unnecessary castSimon Ser
2021-01-29xwayland/selection: end incr transfer on empty prop, not next selectionTudor Brindus
Previously, `transfer->incr` was being cleared on the next selection. However, if the next selection was *also* incremental, it's possible that `xwm_handle_selection_property_notify` would route us to `xwm_get_incr_chunk` instead of `xwm_selection_get_data`.
2021-01-29xwayland/selection: refactor remaining incremental transfer codeTudor Brindus
2021-01-29xwayland/selection: extract out property requestsTudor Brindus
Apart from reducing duplication, this has the positive side-effect of allowing all deallocs to use `xwm_selection_transfer_destroy_property_reply`, as opposed to the latter and a mix of ad-hoc `free`s.
2021-01-29xwayland/selection: simplify incremental transfer control flowTudor Brindus
Previously, if the Wayland client died before an incremental transfer was complete, the logs would be spammed by "write error to target fd" as wlroots entered some control flow wherein it'd continually try scheduling further writes to the already-dead pipe. This commit contains no behavioral changes, but introduces explicit handling for draining the X11 selection in case of Wayland client death.
2021-01-29xwayland/selection: explicitly bail if first write to Wayland fd failsTudor Brindus
If `xwm_data_source_write` failed, it's failed permanently. In fact, a failing `xwm_data_source_write` sets `transfer->property_reply` to null as part of its error handling. Instead of relying on an indirect check (whether `transfer->property_reply` is still non-null), explicitly use the return value from `xwm_data_source_write`.
2021-01-29xwayland/selection: make `xwm_data_source_write` return 0 on failureTudor Brindus
The `fd` is marked `O_NONBLOCK`, so `write` will never spuriously return `EINTR`. Therefore, `write` failing is permanent, and we can return 0 to make the return value meaningful.
2021-01-29render/egl: remove *config_attribs and wlr_egl->configBrandon Dowdy
Breaking changes: Both "EGLint *config_attribs" and "wlr_egl->config" no longer exist.
2021-01-29render/egl: remove wlr_egl_{create,destroy}_surfaceBrandon Dowdy
Breaking changes: wlr_egl_create_surface and wlr_egl_destroy_surface have been removed and no longer exist.
2021-01-29examples: remove dependency on wlr_egl from clientsBrandon Dowdy
The specified clients in this commit used to rely on wlr_egl and some of its related functions in order to render surfaces. This is no longer the case as of this commit.
