Define _POSIX_C_SOURCE globally

2024-02-15T14:41:12+00:00

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 and ensure that apart from symbols defined there the file only uses POSIX toys.

backend/multi: emit destroy signal before destroying child backends

2024-01-25T11:12:13+00:00

Some users might want to destroy the multi backend when a child backend is being destroyed. However, they can't destroy the multi backend if it's already in the process of being destroyed. The destroy signal was changed to be emitted after destroying child backends in babdd6ccf757 ("backend: fix use-after-free when destroying backends"). However, this was done to accomodate for an old "output_remove" event on backends, which has long been dropped in favor of wlr_output.events.destroy. This patch follows the same principle as 5d639394f3e8 ("types/output: emit destroy event before destroying global").

backend: drop wlr_backend_get_presentation_clock()

2023-10-30T17:39:39+00:00

We can just assume CLOCK_MONOTONIC everywhere. Simplifies the backend API, and fixes clock mismatches when multiple backends are used together with different clocks.

treewide: Migrate from sizeof(struct) to sizeof(*pointer) where practical

Use wl_container_of() instead of casts

2023-07-11T18:16:17+00:00

This slightly improves type safety. The culprits were found with: git grep -E '\([a-z0-9_ ]+ \*\)\W?[a-z]'

backend: drop wlr_backend_get_session()

2022-11-15T21:16:25+00:00

This no longer has purpose.

Use wl_signal_emit_mutable
