verify-patch-sanity.py validates every active recipe .patch has internally- consistent hunk line counts — catching the 'malformed patch at line N' failure at commit/CI/preflight time instead of hours into a cook. This cycle hit that class three times (qtwaylandscanner, sddm, xwayland), each only discovered when cookbook tried to apply the patch. Running it across the repo found 29 latent malformed patches (validated against GNU patch: e.g. relibc/P3-sysv-ipc reproduces 'malformed patch at line 22'). They were harmless only because they sit in vendored recipes (baked, not re- applied) — but would fail on any version-bump re-derivation. --fix recounts the hunk headers (body untouched) and repaired all 29. Wired into build-preflight.sh (Phase 1.0D) and redbear-ci.yml, with a unit test (test-patch-sanity.sh). Skips archived/legacy trees and unvalidatable formats (empty placeholders, bare-@@ git hunks).

PSTL integration
|
|
================
|
|
|
|
The PSTL (or Parallel STL) project is quite complex in its current form and does not provide everything that libc++
|
|
requires, for example ``_LIBCPP_HIDE_FROM_ABI`` or similar annotations and including granularized headers. Furthermore,
|
|
the PSTL provides various layers of indirection that make sense in a generic implementation of the parallel algorithms,
|
|
but are unnecessarily complex in the context of a single standard library implementation. Because of these drawbacks, we
|
|
decided to adopt a modified PSTL in libc++. Specifically, the goals of the modified PSTL are
|
|
|
|
- No ``<__pstl_algorithm>`` and similar glue headers -- instead, the implementation files are included directly in
|
|
``<algorithm>`` and friends.
|
|
- No ``<pstl/internal/algorithm_impl.h>`` and ``<pstl/internal/algorithm_fwd.h>`` headers and friends -- these contain
|
|
the implementation and forward declarations for internal functions respectively. The implementation lives inside
|
|
``<__algorithm/pstl_any_of.h>`` and friends, and the forward declarations are not needed inside libc++.
|
|
- No ``<pstl/internal/glue_algorithm_defs.h>`` and ``<pstl/internal/glue_algorithm_impl.h>`` headers and friends --
|
|
these contain the public API. It lives inside ``<__algorithm/pstl_any_of.h>`` and friends instead.
|
|
- The headers implementing backends are kept with as few changes as possible to make it easier to keep the backends in
|
|
sync with the backends from the original PSTL.
|
|
- The configuration headers ``__pstl_config_site.in`` and ``pstl_config.h`` are removed, and any required configuration
|
|
is done inside ``__config_site.in`` and ``__config`` respectively.
|
|
- libc++-style tests for the public PSTL API
