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.
2023-08-03Avoid using memcpy() to copy structsSimon Ser
We can just use a regular assignment instead. This is more type-safe since there is no need to provide the struct size. The remaining memcpy() calls perform array copies or copies from void pointers (which may be unaligned).
2023-07-11Use wl_container_of() instead of castsSimon Ser
This slightly improves type safety. The culprits were found with: git grep -E '\([a-z0-9_ ]+ \*\)\W?[a-z]'
2022-12-06build: unify naming for HAVE_* definesSimon Ser
We sometimes used HAS_, sometimes polluted the LIBINPUT_ namespace, etc.

2021-09-01render/allocator: re-open GBM FDSimon Ser
Using the same DRM file description for the DRM backend and for the GBM allocator will result in GEM handle ref'counting issues [1]. Re-open the DRM FD to fix these issues. [1]: https://gitlab.freedesktop.org/mesa/drm/-/merge_requests/110
