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.

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.
On some terminals under default settings, black is truly rendered as
`#000`, making it unreadable when the background is also black.
Refs swaywm/sway#5141.
When colors aren't used, write the log importance to stderr. This makes
it easier to grep for errors and avoids mistaking error messages for
debug messages.
The Wayland protocol specifies output transform rotations to be
counterclockwise and applied to the surface. Previously, wlroots
copied Weston and incorrectly made rotations act clockwise on
surfaces. This commit fixes that.
This change will break compositors which expect transform rotations
to be clockwise, and the rare applications that make use of surface
transforms.

- Remove all intermediate static libraries.
They serve no purpose and are just add a bunch of boilerplate for
managing dependencies and options. It's now managed as a list of
files which are compiled into libwlroots directly.
- Use install_subdir instead of installing headers individually.
I've changed my mind since I did that. Listing them out is annoying as
hell, and it's easy to forget to do it.
- Add not_found_message for all of our optional dependencies that have a
meson option. It gives some hints about what option to pass and what
the optional dependency is for.
- Move all backend subdirectories into their own meson.build. This
keeps some of the backend-specific build logic (especially rdp and
session) more neatly separated off.
- Don't overlink example clients with code they're not using.
This was done by merging the protocol dictionaries and setting some
variables containing the code and client header file.
Example clients now explicitly mention what extension protocols they
want to link to.
- Split compositor example logic from client example logic.
- Minor formatting changes
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.
This commit matches sway's 2dc4978d8af326c310057ca8fd22a4c7f5d09335.
To help ensure a reproducible build (when debug info is disabled),
the meson build script now uses the -fmacro-prefix-map command line
argument supported by GCC to strip the build-path dependent bytes
of each __FILE__ string used by wlr_log and related functions.
A rather ugly algorithm is used to compute the relative path between
the build and source folders, because meson has no specific function
for this.
When the compiler does not support -fmacro-prefix-map, fall back
to shifting the start of each __FILE__ string by the length of the
relative path to the source directory.
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).

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.
I do not think the conversion is specifically defined, but on my system and SirCmpwn's
the floats are rounded instead of floored, which is incorrect in this case, since
for a range from 0 to 256, any value greater or equal to 0 and less than 256 is valid.
I.e. [0;256[, or 0 <= x < 256, but if x is e.g. -0.1, then it will be rounded to 0, which
is invalid. The correct behavior would be to floor to -1.
Even if the file is removed right away, a race with someone using inotify
is definitely possible, so play safe and restrict umask for our tmpfiles
