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.
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.
If the display is destroyed before wlr_global_destroy_safe's timer
fires, the struct destroy_global_data is leaked. This shouldn't cause
issues in practice because the timer will never fire, but makes it
harder to spot compositor memory leaks.
When testing Xwayland multi-HiDPI support with Wine + SimCity4
I encountered a 100% CPU lockup from sway. This turned out to be
triggering a bug in the wlroots pointer contraint code.
region_confine() contains multiple recursive calls where arguments
are modified and resubmitted to the function. One of the calls
is however made using the original arguments, if/when this triggers
it results in the same codepath being followed each loop so the
condition always applies.
It makes much more sense if this was intended to apply the clamped
values x,y instead of the original x1,y1, and indeed this fixes the
infinite loop and results in correct behaviour.
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.
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.

Fixes#2616
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.
