2020-06-19output: make rollback_render mandatorySimon Ser
If the output backend provides attach_render, assert it also provides a way to revert it via rollback_render.
2020-06-19output: rename impl->rollback to rollback_renderSimon Ser
The output backend API is now mostly state-less thanks to the atomic hooks (commit and test). There is one exception though: attach_render. This function makes the rendering context current. However sometimes the compositor might decide not to render after attach_render (e.g. when there's nothing new to render to the back buffer). Thus wlr_output_rollback has been introduced to revert the pending state. Because the output backend API is mostly state-less, the only thing wlr_output_impl.rollback needs to do is revert the current rendering context. Rename the function to rollback_render to make this clear. Add a check in the common wlr_output code to only call rollback_render when attach_buffer has been previously called. On the long term, we'll be able to remove attach_render and rollback_render together.
2020-06-18render/egl: print error nameSimon Ser
Allows for easier debugging.
2020-06-18surface: ignore viewport src rect on NULL bufferSimon Ser
According to the viewporter protocol: > If the wl_buffer is NULL, the surface has no content and therefore no size.
2020-06-18surface: don't unset width and height in finalizeRouven Czerwinski
During surface finalization we may not have received a new buffer, resetting width and height in this case is wrong since we display the old buffer in this case.
2020-06-17input/keyboard: send modifiers on first keyboard enterTudor Brindus
Will fix Firefox bug https://bugzilla.mozilla.org/show_bug.cgi?id=1643991. Fixes swaywm/sway#5462.
2020-06-17viewporter: new protocol implementationSimon Ser
Closes: https://github.com/swaywm/wlroots/issues/633
2020-06-17surface: introduce wlr_surface_get_buffer_source_boxSimon Ser
This helper allows compositors to retrieve the buffer source box in buffer-local coordinates.
2020-06-17surface: add wlr_surface_state.viewportSimon Ser
This field contains the viewport source and destination parameters. It's intended to be updated by a third-party protocol, for instance viewporter.
2020-06-17render: add wlr_render_subtexture_with_matrixSimon Ser
This renders only a subset of the texture, instead of the full texture.
2020-06-17util/region: add wlr_region_scale_xySimon Ser
2020-06-17box: add wlr_fboxSimon Ser
Same as wlr_box, but for floating-point numbers.
2020-06-17render/gles2: use .x/.y instead of .s/.tSimon Ser
texcoord is a vector of coordinates, with the first member being the X axis value and the second member being the Y axis value. It makes more sense to use the accessors with the same names.
2020-06-16render: assert sane values for box functionsRouven Czerwinski
Width and height should always be > 0 for render functions which take a wlr_box. References https://github.com/swaywm/wlroots/issues/2281

2020-06-11examples/fullscreen-shell: stop advertising linux-dmabuf unconditonallySimon Ser
Remove the wlr_linux_dmabuf_v1_create call. wlr_renderer_init_wl_display will take care of creating the linux-dmabuf global if the OpenGL implementation supports it.
2020-06-11examples/screencopy-dmabuf: call strncpy with maxlen - 1Simon Ser
The original code wasn't wrong since we were manually writing a null byte anyway, but this makes GCC happy. Closes: https://github.com/swaywm/wlroots/issues/2273
2020-06-10render/egl: explicit client extension handlingSimon Ser
Prior to this commit, wlr_egl_init seemed to assume the extension string queried via EGL_NO_DISPLAY was a subset of the extension string queried via an initialized display. This isn't correct. EGL_EXT_client_extensions [1] defines two types of extensions: client extensions and display extensions. The set of supported client and display extensions are disjoint (ie. an extension is either a client or a display extension, not both). Client extensions are queried via EGL_NO_DISPLAY, display extensions are queried via an initialized display. Rename the variables to make this clear. Remove the misleading comment. Log both client and display extensions. [1]: https://www.khronos.org/registry/EGL/extensions/EXT/EGL_EXT_client_extensions.txt

2020-06-08backend/drm: fix stack overflow in dealloc_crtcSimon Ser
Call drm_crtc_commit directly instead of calling drm_connector_set_mode. This restores the previous behaviour where conn_enable was called [1].

2020-06-06render: choose DMA-BUF texture target via eglQueryDmaBufModifiersEXTSimon Ser
EGL_EXT_image_dma_buf_import_modifiers tells us whether we should use GL_TEXTURE_2D or GL_TEXTURE_EXTERNAL_OES. Using the right texture target can fix some failures and/or improve performance on some drivers. This does the same as a Weston commit [1].

2020-06-06util/time: move `timespec_sub` to time utilitiesTudor Brindus
2020-06-06util/time: de-duplicate `timespec_to_msec`Tudor Brindus
2020-06-06util: fix and move `get_current_time_msec` into a util fileTudor Brindus
This commit makes `get_current_time_msec` correctly return milliseconds as opposed to microseconds. It also considers the value of `tv_sec`, so we don't lose occasionally go back in time by one second. Finally, the function is moved into `util/time.cc` so that it can be reused elsewhere without having to consider these pitfalls.
2020-06-05Allow keyboard and pointer grabs to hook clear_focus()Thomas Hebb
This is necessary for some grabs, which currently have no way of knowing when the pointer/keyboard focus has left a surface. For example, without this, a drag-and-drop grab can erroneously drop into a window that the cursor is no longer over. This is the plumbing needed to properly fix swaywm/sway#5220. The existing fix, swaywm/sway#5222, relies on every grab's `enter()` hook allowing a `NULL` surface. This is not guaranteed by the API and, in fact, is not the case for the xdg-shell popup grab and results in a crash when the cursor leaves a surface and does not immediately enter another one while a popup is open (#2161). This fix also adds an assertion to wlr_seat_pointer_notify_enter() that ensures it's never called with a `NULL` surface. This will make Sway crash much more until it fixes its usage of the API, so we should land this at the same time as a fix in Sway (which I haven't posted yet).
2020-06-05wlr_seat: Clarify wording of non-grab-respecting function commentsThomas Hebb
I found the previous wording a bit confusing when I first read it. Reword these comments to explicitly say that the grab-respecting variants should be used in most cases. This change has no functional effect.
2020-06-05wlr_seat: Declare functions in the same order for pointer, keyboard, and touchThomas Hebb
These three APIs are very similar to one another, but they all had slightly different function orderings. For consistency, always declare the non_`notify` functions first, then the `notify` functions, then `{start,end,has}_grab`. This change has no functional effect.

2020-06-02render: stop making EGL context current in wlr_egl_initSimon Ser
This leaves an EGL context current behind. wlr_gles2_renderer_create was assuming the EGL context was already current because of this (because it called a GL function right off the bat).
2020-06-02backend/wayland: fix spurious eglSwapBuffers failuresSimon Ser
This was introduced in [1]. However after reverting that PR I still can't reproduce the bug the PR aimed to fix [2]. Since there's no good explanation why we would need to swap buffers before resizing, let's just revert the PR. [1]: https://github.com/swaywm/wlroots/pull/1486 [2]: https://github.com/swaywm/wlroots/issues/1371 Closes: https://github.com/swaywm/wlroots/issues/1768

Fixes #2233.
2020-06-01backend/drm: always perform a CRTC commit in drm_connector_commitSimon Ser
When the mode, status or buffer hasn't changed, drm_connector_commit was a no-op. Because of this individual changes to the gamma LUT or adaptive sync status were ignored (if committed without a buffer). Instead, perform a commit to apply the changes.
2020-06-01backend/drm: drop extra wlr_output_update_enabled callSimon Ser
drm_connector_set_mode already takes care of keeping this up-to-date.

Stop using drmModeObjectSetProperty, set the property in the crtc_commit function instead.
2020-06-01backend/drm: rollback pending CRTC state on test commitSimon Ser
A test commit doesn't apply the pending state. The CRTC state will be populated again if the compositor decides to perform a regular commit afterwards.
2020-06-01export-dmabuf: Keep frame->output = NULL until frame is readyAndri Yngvason
This fixes a crash that happens when a client requests a frame on a backend that does not implement export_dmabuf. An assertion fails with the message: sway: types/wlr_output.c:777: wlr_output_lock_attach_render: Assertion `output->attach_render_locks > 0' failed.
2020-05-31wlr_keyboard_group: introduce enter and leaveBrian Ashworth
This introduces the enter and leave events for wlr_keyboard_group. The enter event is emitted when a keyboard is added to the group while a key is pressed that is not pressed by any other keyboard in the group. The data is a wl_array of the pressed key codes unique to the keyboard that should now be considered pressed. Similarly the leave event is emitted when a keyboard is removed from the group while at least one key is pressed that is not pressed by any other keyboard in the group. The data is a wl_array of the pressed key codes unique to the keyboard that should now be considered released. The purpose of these events are to allow the compositor to update its state to avoid corruption. Additionally, for the leave event, the focused surface may have been notified of a key press for some or all of the key codes and needs to be notified of a key release to avoid state corruption. These were previously emitted as normal key events, but they are not normal key events. There is no actual key press or release associated with the events. It's purely for state keeping purposes. Emitting them as separate events allows the compositor to handle them differently. Since these are purely for state keeping purposes and are not associated with an actual key being pressed or released, bindings should not be triggered as a result of these events.
