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.
Having 1.16 results in the following error when running the compositor:
2019-04-27 17:30:50 - [wayland] wl_global_create: implemented version for 'wl_seat' higher than interface version (7 > 6)
2019-04-27 17:30:50 - [sway/input/seat.c:428] seat_create:could not allocate seat
We require wayland-server >= 1.17 for wl_seat version 7.

There was an issue in 0.51.1 and earlier, where lists of dependencies
and disablers weren't acting like they should. Instead of disabling a
build, it would error out instead.
Changing this logic to work around it is annoying, so just bump the
version instead.
This is insanely fruststating. Since it works off of currently committed
git files, if you ever remove anything, your build will fail until you
commit it.
It doesn't even belong in the build system anyway, as it's only part of
an individual's specific workflow. Use for own scripts for your own
workflow. Go use some git hooks to generate this or something.
Bumps minimum version to 0.51.0
- 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
This requires functions without a prototype definition to be static.
This allows to detect dead code, export less symbols and put shared
functions in headers.
Eliminates this warning when building wlroots as a subproject:
subprojects/wlroots/meson.build:216: DEPRECATION: Library wlroots
was passed to the libraries keyword argument of a previous call
to generate() method instead of first positional argument. Adding
wlroots to Requires field, but this is a deprecated behaviour
that will change in a future version of Meson. Please report the
issue if this warning cannot be avoided in your case.
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.
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.
The Meson option "b_lundef" need to be set to false on FreeBSD, because
the symbol "environ" is in crt1.o, which is not linked with shared
libraries. With Meson >=0.48.0 it is possible to set this option only
for FreeBSD. This patch changes meson.build to do that.
