2023-11-22xdg-toplevel: check that title provided actually is UTF-8Manuel Stoeckl
While the xdg-shell protocol requires this, it does not yet have a dedicated error code for invalid titles; this commit makes wlroots send a generic error instead.

2023-10-26util/token: rename TOKEN_STRLEN to TOKEN_SIZESimon Ser
TOKEN_STRLEN is not actually the strlen() of the token. It's the size taken by the token included the final zero byte. Change the name to make this clearer, and remove unnecessary +1's.
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.

2022-12-06util/env: make env_parse_switch() return a size_tSimon Ser
This function is guaranteed to never return a negative value. This is important because we use arr[env_parse_switch(...)] in a few places.
2022-12-06util/env: add docsSimon Ser
I always forget what env_parse_switch() does on error.
2022-11-25util/time: use int64_t return value for get_current_time_msec()Simon Ser
0xFFFFFFFF milliseconds is 4,294,967,295 ms so about 50 days. A little bit too close for comfort. Use int64_t instead of uint64_t to avoid C's implicit conversion footguns in computations.

2022-08-19util/array: Add array_realloc for wl_arrayKenny Levinsen
array_realloc will grow the array for the target size like wl_insert_add, but will also shrink the array if the target size is sufficiently smaller than the current allocation.

2021-12-14util/global: remove wl_display arg from wlr_global_destroy_safeSimon Ser
Since [1], we can get the wl_display directly from the wl_global. [1]: https://gitlab.freedesktop.org/wayland/wayland/-/commit/2b22160fb690a76247aa9bd0be3069ff43e8239f
2021-09-05util/shm: add allocate_shm_file_pairSimon Ser
This function behaves like allocate_shm_file, except it also returns a read-only FD. This is useful to share the same segment of memory with many Wayland clients.

2021-04-11util/uuid: replace with util/token, remove libuuidRyan Farley
Use 128-bit hexadecimal string tokens generated with /dev/urandom instead of UUIDs for xdg-foreign handles, removing the libuuid dependency. Update readme and CI. Closes #2830. build: remove xdg-foreign feature With no external dependencies required, there's no reason not to always build it. Remove WLR_HAS_XDG_FOREIGN as well.

2020-12-18util/time: add timespec_from_nsecSimon Ser
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.
2020-02-17util: add wlr_output_destroy_safeSimon Ser
This adds a generic helper to destory transient globals. See [1]. This patch depends on [2] and [3].

2019-07-27Remove all wayland-server.h includesSimon Ser
The documentation for wayland-server.h says: > Use of this header file is discouraged. Prefer including > wayland-server-core.h instead, which does not include the server protocol > header and as such only defines the library PI, excluding the deprecated API > below. Replacing wayland-server.h with wayland-server-core.h allows us to drop the WL_HIDE_DEPRECATED declaration.
2019-06-16Use a set to track pointer button state.Ashkan Kiani
In addition to `button_count`, we keep track of the current buttons pressed just as in `wlr_keyboard`. Add `set_add` and `set_remove` to assist with this. These functions can only be used with values greater than 0 (such as the button/key masks for keyboards and pointers). Partially addresses: - https://github.com/swaywm/wlroots/issues/1716 - https://github.com/swaywm/wlroots/issues/1593
2018-10-28util: use shm_open for in-memory filesemersion
shm_open is a POSIX function creating an in-memory file. Using it simplifies the code and removes the dependency on XDG_RUNTIME_DIR. The only downside is that we need to generate a random name for the shm file.
