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.

util/log: drop unnecessary _XOPEN_SOURCE

2024-02-15T14:20:14+00:00

snprintf() is actually ISO C99. We still need POSIX for clock_gettime().

util/transform: add wlr_output_transform_coords()

2023-11-23T10:07:34+00:00

We hand-roll this in multiple places.

util/transform: move over wl_output_transform helpers

2023-11-23T10:03:57+00:00

These aren't really tied to wlr_output.

xdg-toplevel: check that title provided actually is UTF-8

2023-11-22T19:03:00+00:00

While the xdg-shell protocol requires this, it does not yet have a dedicated error code for invalid titles; this commit makes wlroots send a generic error instead.

util/token: rename TOKEN_STRLEN to TOKEN_SIZE

2023-10-26T16:30:12+00:00

TOKEN_STRLEN is not actually the strlen() of the token. It's the size taken by the token included the final zero byte. Change the name to make this clearer, and remove unnecessary +1's.

util/addon: make wlr_addon_set_finish() safer

2023-10-08T11:06:09+00:00

wl_list_for_each_safe() breaks if an item immediately after the current one is removed, see https://gitlab.freedesktop.org/wlroots/wlroots/-/merge_requests/4358#note_2106260.

util: add struct to track union of rectangles

2023-10-05T11:45:32+00:00

The new struct rect_union is designed to make it easier to efficiently accumulate a list of rectangles, and then operate on an exact cover of their union. Using rect_union, the times needed to added t rectangles, and then compute their exact cover will be O(t), and something between Ω(t) and O(t^2), depending on the rectangle arrangement. If one tries to do the same by storing a pixman_region32_t and updating it with pixman_region32_union_rect(), then total time needed would be between Ω(t^2) and O(t^3), depending on the input. Without changing the public API (data structure + rectangle ordering rules) for pixman_region32_t, it is impossible to improve its worst case time.

Use struct initializers instead of memset()

2023-07-07T15:31:11+00:00

This is a bit more type-safe.

util/log: fix buffer overflow
