2023-10-09output: allow_artifacts -> allow_reconfigurationKenny Levinsen
The name "allow_artifacts" and associated description is very vague, and theoretically allow for tearing behavior. Clarify that we only intend to mean artifacts related to output configuration (e.g., modesets). References: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3740
2023-10-08scene/output_layout: Add assert for duplicate output insertionAlexander Orzechowski
Ensure that the output was not added multiple times to the scene output layout.

Add recommendations for the most common mistakes when reporting an issue.
2023-10-08util/addon: make wlr_addon_set_finish() saferKirill Primak
wl_list_for_each_safe() breaks if an item immediately after the current one is removed, see https://gitlab.freedesktop.org/wlroots/wlroots/-/merge_requests/4358#note_2106260.

2023-10-07scene_output_layout: Don't destroy output when output layout is destroyedAlexander Orzechowski
There were a couple of problems with this: 1. The behavior is unexpected. Typically objects in wlroots won't also destroy objects that they depend on. For instance, wlr_scene_output will not destroy the wlr_output when it's destroyed. It shouldn't be any different for scene layouts. 2. This fixes a crash where because wlr_output_layout and wlr_scene_output are both addons to wlr_output, we might get into a situation where wl_list_for_each_safe might malfunction. See [1] This means that the compositor needs to manually destroy the output when they destroy the layout, hence ~breaking. Compositors can just call `wlr_scene_output_destroy()` if they want to destroy both at the same time. [1] https://gitlab.freedesktop.org/wlroots/wlroots/-/merge_requests/4358#note_2106260 This reverts commit 1a731596c5bcd252d8796cacb59af8b20ceb914f. Co-authored-by: Kirill Primak <vyivel@eclair.cafe>
2023-10-06output_event_commit: Remove committed and bufferAlexander Orzechowski
The newly introduced state struct can be used to retrieve this.

2023-10-06render/allocator: log message when GBM is disabledSimon Ser
When the backend and renderer would need GBM but it's disabled at compile-time, log a message to make this situation easier to debug.
2023-10-06render: log error when requested renderer is compile-time disabledSimon Ser
It can be a bit confusing to debug when the user requests an explicit renderer but it's disabled at build-time. Log an error when that happens.
2023-10-06seat: remove wlr_seat_validate_grab_serial()Kirill Primak
It makes little sense to have a catch-all grab vaildation function, considering that e.g. tablet tool implicit grabs are possible as well. Besides, the function has always returned true anyway.
2023-10-06xwayland: batch client ID request with other property requestsSimon Ser
2023-10-06xwayland: batch property requests when handling new windowSimon Ser
Instead of sending one request, waiting for the reply, and repeating for all properties we're interested in, we can send all property requests in one go and then wait for the server to reply.

2023-10-05render/drm_format_set: use published kernel doc URLSimon Ser
The kernel patch has been merged, so this is available in the official docs now.
2023-10-05render/vulkan: constrain blend to output subpass to redrawn regionManuel Stoeckl
This commit only applies to the render pass API.
2023-10-05util: add struct to track union of rectanglesManuel Stoeckl
The new struct rect_union is designed to make it easier to efficiently accumulate a list of rectangles, and then operate on an exact cover of their union. Using rect_union, the times needed to added t rectangles, and then compute their exact cover will be O(t), and something between Ω(t) and O(t^2), depending on the rectangle arrangement. If one tries to do the same by storing a pixman_region32_t and updating it with pixman_region32_union_rect(), then total time needed would be between Ω(t^2) and O(t^3), depending on the input. Without changing the public API (data structure + rectangle ordering rules) for pixman_region32_t, it is impossible to improve its worst case time.
2023-10-05renderer: Don't crash when trying to fallback to pixmanAlexander Orzechowski
Pixman won't be chosen by default if the system has a valid render node but gles2 and vulkan creation failed.

2023-10-02output_defer_present: Calloc right structAlexander Orzechowski
2023-10-02output: defer fake present events until after commitRose Hudson
Since headless and wayland-without-presentation-feedback were firing present inside their commit impls, present was getting fired before commit, which is cursed. Defer this with an idle timer so that commit handlers can run before present handlers.
2023-10-02backend/drm: restore pending page-flip check when tearingSimon Ser
DRM_MODE_PAGE_FLIP_ASYNC doesn't allow user-space to submit new buffers before waiting for the uevent: the kernel will return EBUSY in that case. Fixes: c2aa7fd965cb ("backend/drm: Add async page flip support to legacy")
2023-10-02cursor: Unset cursor if texture upload failedAlexander Orzechowski
We need to make sure cursor_output_cursor_update() will clear the old texture references through all code paths.
2023-10-02cursor: Remove dead codeAlexander Orzechowski
This conditional would never fire because `cursor_output_cursor_reset_image` nulls the previous xcursor.
2023-10-02cursor: Unset cursor image when there is not available xcursor themeAlexander Orzechowski
This fixes a crash in the case where the last cursor was a client surface cursor but then transitioned into a server managed xcursor that isn't available. Because the logic would return early before, we would continue to reference a texture pointer belonging to a client surface but would otherwise disassociate with it (we wouldn't clear the cursor if the surface is destroyed) resulting an an eventual UAF. Let's just make the cursor invisible if we don't know what to show. It's compositor policy if they want to show a default. Co-authored-by: Scott Moreau <oreaus@gmail.com> Fixes: #3686

2023-09-27Fix possible crash in server-decoration when surface destroyedBrian J. Tarricone
If the underlying surface is destroyed, but the client has not yet destroyed the server decoration object, and then tries to call request_mode() on it, the compositor will crash, because the wlr_server_decoration struct has been freed, and the wl_resource's user_data member has been NULLed out. Yes, this is certainly an error for the client to do that, but I shouldn't be able to write a buggy (or malicious) Wayland app that can take down the entire compositor.
2023-09-22wlr_scene: clarify wlr_scene_output ownership semanticsJohn Lindgren
wlr_scene_output_layout_add_output() was made public by f5917f024760 ("scene_output_layout: make output adding explicit") but the ownership semantics are not obvious and should be clarified.

2023-09-21render/pass: Introduce wlr_render_rect_options_get_boxAlexander Orzechowski
2023-09-11screencopy_v1: only bind, not render with, buffer in shm copy pathManuel Stoeckl
wlr_renderer_read_pixels does not need to be called inside a render pass; rather, it only needs to have the correct buffer bound to the renderer. This commit optimizes the implementation of frame_shm_copy(...) by only binding the source buffer instead of starting a no-op render pass with it.
2023-09-11output: Mutate frame_pending needs_frame when there is an explicit output commitAlexander Orzechowski
These states would be set if output_init is invoked with a enabled state. This would make frame_pending == true which means wlroots will ignore any further frame events and the compositor will appear dead.
2023-09-10render/vulkan: fix validation error with vkCmdBlitImageManuel Stoeckl
Specfically, VUID-vkCmdBlitImage-srcImage-00247.
2023-09-09render/vulkan: de-duplicate VkImageUsageFlagsSimon Ser
The flags passed to vkCreateImage() must match the flags used when querying formats. Make this clearer by using the same variable.

2023-08-25backend/drm: drop no-op shortcutSimon Ser
Since e5fc8cd4c734 ("output: trigger frame/present events on all commits on enabled output"), any commit on an enabled output is supposed to trigger frame/present events. The DRM backend was skipping the commit completely for no-op commits. Stop doing so. Closes: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3719
2023-08-24render/pass: ensure rect has positive sizeSimon Ser
