2024-02-15Define _POSIX_C_SOURCE globallySimon Ser
Stop trying to maintain a per-file _POSIX_C_SOURCE. Instead, require POSIX.1-2008 globally. A lot of core source files depend on that already. Some care must be taken on a few select files where we need a bit more than POSIX. Some files need XSI extensions (_XOPEN_SOURCE) and some files need BSD extensions (_DEFAULT_SOURCE). In both cases, these feature test macros imply _POSIX_C_SOURCE. Make sure to not define both these macros and _POSIX_C_SOURCE explicitly to avoid POSIX requirement conflicts (e.g. _POSIX_C_SOURCE says POSIX.1-2001 but _XOPEN_SOURCE says POSIX.1-2008). Additionally, there is one special case in render/vulkan/vulkan.c. That file needs major()/minor(), and these are system-specific. On FreeBSD, _POSIX_C_SOURCE hides system-specific symbols so we need to make sure it's not defined for this file. On Linux, we can explicitly include <sys/sysmacros.h> and ensure that apart from symbols defined there the file only uses POSIX toys.
2024-01-17xwayland: close pipe fds on set_cloexec() errorKirill Primak
2023-10-10xwayland/server: add ready flagSimon Ser
Allows one to check whether the server is currently ready.
2023-10-03treewide: Migrate from sizeof(struct) to sizeof(*pointer) where practicalAlexander Orzechowski
2022-12-06xwayland: use internal_configSimon Ser
Avoids the need to have a separate config.h, and removes C compiler arguments.
2022-11-18xwayland/server: delay non-lazy startupSimon Ser
This allows users to setup event listeners before the server is actually started.
2022-11-18xwayland/server: add start signalSimon Ser
This can be used to know when wlr_xwayland_server decides to start a new Xwayland process. At that point the wl_client has already been created but the Xwayland process hasn't been started yet.
2022-08-18Use wl_signal_emit_mutableAlexander Orzechowski
2022-05-23xwayland: Add support for -force-xrandr-emulationJoshua Ashton
2022-05-07xwayland: add wlr_xwayland_server_options.terminate_delaySimon Ser
This allows users to specify a delay after which the Xwayland process terminates itself when there are no more X11 clients connected.
2022-03-02Xwayland: use -displayfd instead of USR1Dominique Martinet
Using Xwayland -displayfd means we don't need to worry about handling SIGUSR1 to second guess when Xwayland is ready and write to the pipe: just let it do that write when it would be sending SIGUSR1 otherwise. Closes: #3356
2022-03-02Xwayland: rename notify pipe 'p' to notify_fdDominique Martinet
2021-11-02xwayland: add support for -noTouchPointerEmulationSimon Ser
This allows compositors to handle touch pointer emulation manually, instead of having Xwayland do it [1]. [1]: https://gitlab.freedesktop.org/xorg/xserver/-/merge_requests/691
2021-07-27xwayland: embed wlr_xwayland_server_options in server structSimon Ser
As more options are added, more fields will be duplicated. Let's just embed the struct in wlr_xwayland_server so that we don't need to keep both in sync.
2021-07-27xwayland: simplify argv filling logicSimon Ser
Remove fill_arg and replace it with stack-allocations and simple array-filling.
2021-06-25xwayland: improve startup log messageSimon Ser
Logging the raw Xwayland command-line was incomplete, uninformative and confusing for end-users. Instead, print a proper message in English.
2021-05-12xwayland: actually use Xwayland from pkg-configThomas Weißschuh
eec2e1d3b16ba40c85483badcc7809277274ce5d introduced logic to use the Xwayland binary discovered via pkg-config. While the newly introduced checks correctly used the binary from pkg-config, the actual execution still used the previous PATH-search logic.
2021-03-03xwayland: use -listenfd if availableSimon Ser
Xwayland's -listen option was deprecated in [1] in favor of -listenfd. [1]: https://gitlab.freedesktop.org/xorg/xserver/-/merge_requests/593
2021-03-03xwayland: check executable exists on initSimon Ser
Instead of walking PATH like a previous proposal [1], this one checks that the Xwayland path specified in the pkg-config file exists. I think this is a reasonable compromise: - Users that don't have Xwayland installed system-wide won't get a bogus DISPLAY env variable set up. - Users that have WLR_XWAYLAND set won't be affected by this check. - Users that have Xwayland installed system-wide and a different Xwayland in their PATH still get their custom Xwayland. - Users that don't have Xwayland installed system-wide but have it somewhere else in PATH are left out. But this is pretty niche, and they can just set WLR_XWAYLAND. [1]: https://github.com/swaywm/wlroots/pull/2314
2020-12-19xwayland: avoid crash on repeated server_finish_display() callIsaac Freund
This function may end up being called more than once if the Xwayland binary does not exist on the system.
2020-12-07xwayland: use pipe instead of SIGUSR1 to signal readinessDominik Honnef
Closes: https://github.com/swaywm/wlroots/issues/2154
2020-12-02xwayland: add -core to flagsSimon Ser
Xwayland has its own special handling for signals like SIGSEGV/SIGABRT. Instead of leaving the job to the OS, it tries to walk up the call stack (badly, because a lot of information is missing), print the stack trace to stdout, then exit(1). This is very annoying because it prevents Xwayland crashes from being easily debugged. Xwayland has a flag "-core" that aborts instead of exiting. This allows the OS to generate a coredump. It's far from perfect but better than nothing, I guess.
2020-10-20xwayland: fix minor typo in debug logTudor Brindus
This accidentally slipped through 1b0e4c7.
2020-10-11xwayland: introduce WLR_XWAYLAND for specifying which Xwayland to useTudor Brindus
When debugging Xwayland-related issues, a common first step in debugging has been to ask the reporter to move their real Xwayland to /usr/bin/Xwayland.bin, and create a shell script starting Xwayland with extra arguments under the original /usr/bin/Xwayland location. Introducing a `WLR_XWAYLAND` environment variable makes this less invasive, by allowing the user to swap out Xwayland without resorting to global system changes (or source patches).
2020-09-04xwayland: disconnect display destroy listener even if xwayland didn't initializeIlia Bozhinov
2020-06-30xwayland: Don't discard ready signalsScott Moreau
The xwayland ready signals are used to do initial setup like starting xwm. Discarding the signals means that the handler functions will not be called in the case that Xwayland is restarted and thus, xwm managed clients fail. Fixes #2174."
2020-05-27xwayland: add error-checking to `server_start_lazy`Tudor Brindus
This prevents a very unlikely crash in `xwayland_socket_connected`. Refs #2163.
2020-05-19xwayland: add option to disable WMSimon Ser
2020-05-19xwayland: split serverSimon Ser
Split the server part of wlr_xwayland into wlr_xwayland_server. This allows compositors to implement their own XWM when wlroots' isn't a good fit.
