render/vulkan: Avoid double-free on calloc error

2024-02-22T22:07:58+00:00

In query_modifier_support, the calloc for either or both of render_mods and texture_mods may fail, in which case both are freed for convenience. However, if one is non-NULL, vulkan_format_props_finish will try to free it again. NULL them to avoid double-free.

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.

render/pixel-format: Move has_alpha into it's own array

2024-01-31T18:47:17+00:00

Some opaque pixel formats (nv12, p010) require per-plane bytes_per_block info. However, it doesn't make sense to store them in wlr_pixel_format_info, as they will never be useful (currently, this info is used for shm, which doesn't have a concept of multi-planar buffers.) Let's define a separate array and function for determining whether a pixel format has alpha.

render/vulkan: fix possible double free

Fix bool return types

2024-01-04T21:24:06+00:00

This makes wlroots build in C23 mode. C23 is more strict and rejects implicit conversions from bool to a pointer.

render/vulkan: use _SRGB image view when possible

2023-12-04T15:13:31+00:00

This is the last of a set of commits which ensures that both textures and render buffers can be accessed through _UNORM and _SRGB image views. While _UNORM image views are not yet used for 8-bpc image formats, they will be needed in the future to support color transforms for both textures and render buffers.
