Switch from the pkg-config dependency names to the upstream
libxcb repository names. Each repository contains multiple
libraries but is generally available in distributions as a single
package.
libxcb contains xcb, xcb-composite, xcb-xfixes, xcb-xinput and
xcb-shm. libxcb-render-util contains xcb-render. libxcb-wm
contains xcb-icccm. xcb-image was outdated and is no longer needed.
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 dependency is already required by many other widely used X11
programs, such as i3, Qt, and other XWMs. So it should be available
on most systems.
X11 support can be pretty broken without xcb-icccm, with focus issues
for instance. Let's just remove this --please-break-my-desktop footgun
option.
Check that the pkg-config file is available. This will be required
in the future to check whether xwayland supports features such as
-listenfd, -initfd or -verbose.
If there's no pkg-config file, check that the Xwayland executable
is available.
This effectively makes our relationship with xwayland closer to what
a dynamic library is: checked at build-time, but can be overridden
at run-time.
This is simply a false sense of security, and is worse than just using
setuid. CAP_SYS_ADMIN is an extremely serious capability that is
effectively as powerful as root.
It also required users to be in the input group, which allows any
process to keylog the entire system.
Changed the contribution guidelines to be more consistent with the style
that wlroots has evolved into, and removed some duplicate information
that already exists in the kernel style.
