Closes what was left of TODO.md sections 1, 2 and 3, and rewrites that
file to hold outstanding items only.
The API break gets a minor bump, because pre-1.0 the soname carries
MAJOR.MINOR and 0.1 and 0.2 are therefore different ABIs. Five
signatures changed and the ato* contract with them; UPGRADING.md is new
and lists every one, with the before/after for the cases the compiler
cannot warn about.
Section 3.1 is finished: reallocarray with the multiplication checked,
aligned_alloc and posix_memalign, asprintf/vasprintf, scanf/vscanf.
Four functions on that list are deliberately absent rather than missing
-- sprintf, strtok, setbuf and perror -- and TODO.md now says which and
why, so nobody adds them thinking they were forgotten.
Section 1.9, the cross-cutting tests:
tests/test_pool.c drives every failure path AKERR_MAX_ARRAY_ERROR
+ 10 times and checks the pool after each round,
because a wrapper that leaks a slot fails a
hundred calls later in unrelated code. It also
asserts that each error names the function and
file it was raised from, which is what catches a
FAIL that migrates into a helper during a
refactor: status right, message right, origin
quietly lying.
tests/negative/ two sources that must FAIL to compile, built with
-Werror and registered WILL_FAIL. AKERR_NOIGNORE
and the format attributes are enforced by the
compiler and by nothing else; drop either and
every ordinary test still passes.
Thread safety is answered rather than tested: the library is not
thread-safe and cannot be made so from here, because libakerror's error
pool is an unlocked process-global array. README.md says so plainly and
TODO.md carries it as the item blocking any future pthread wrappers.
Doxygen is configured and gated. All 147 public functions have @brief,
a @param each, @throws per status and @return; EXTRACT_ALL is off and
WARN_NO_PARAMDOC on, so `cmake --build build --target docs` fails on an
undocumented entity. It ran to 0 warnings. The Doxyfile carries no
version -- cmake/RunDoxygen.cmake feeds PROJECT_NUMBER in from
project(), so that stays the one place a version is written.
CI now builds against the submodule it pins instead of also installing
libakerror@main and never linking it, adds -Werror, and gains a
sanitizer job. The pre-push hook matches, and runs the docs check too.
Coverage: 99.5% of lines (1643/1651), 100% of functions (147/147). The
eight uncovered lines are each uncovered on purpose and TODO.md says
which and why.

Bump deps/libakerror 22 commits to 5ff8790 (1.0.0), which makes the
status-name table private, moves consumer status codes to a band starting
at AKERR_FIRST_CONSUMER_STATUS, enforces range ownership rather than
treating it as advisory, and gives the library an soname. See
deps/libakerror/UPGRADING.md.
src/stdlib.c needed no changes. This library defines no status codes of its
own -- it raises libakerror's AKERR_* codes and propagates errno, both
inside libakerror's reserved 0-255 band -- and it never referenced
AKERR_MAX_ERR_VALUE, __AKERR_ERROR_NAMES, AKERR_STATUS_RANGE_OK or
AKERR_STATUS_NAME_OK. What moved was everything around the code:
A -DAKSL_COVERAGE=ON build stopped configuring at all. libakerror
namespaces its `mutation` target when embedded but not its `coverage`
target, so it collided with ours. Shadow add_custom_target for the duration
of the add_subdirectory() call and rename the dependency's to
akerror_coverage, alongside the existing add_test shadow. Fix upstream and
delete the workaround; recorded in TODO.md.
Pin the 1.0.0 floor three ways, since no single one covers every
consumption path: an #error in akstdlib.h feature-testing
AKERR_FIRST_CONSUMER_STATUS, because libakerror publishes no version macro;
Requires: akerror >= 1.0.0 in akstdlib.pc, which also gets consumers
-lakerror transitively; and find_dependency(akerror) in
akstdlibConfig.cmake. The last was already broken before this bump -- the
template still carried its MyLibraryConfig placeholder with the dependency
commented out, so any external find_package(akstdlib) failed with a bare
"akerror::akerror not found" out of the generated targets file.
Branch coverage of src/stdlib.c fell from 51.0% to 44.3% with no source or
test change: the 1.0.0 PREPARE_ERROR/FAIL_* macros expand to more branches
at every call site, so 337/661 became 481/1087 -- 144 more branches covered,
426 more counted. Line coverage held at 99.0% (200/202) and function
coverage at 100% (21/21). Re-ratchet the CI branch gate 45 -> 40 rather than
chase branches that belong to libakerror's own suite.
tests/test_status_registry.c pins the contract that made the status-code
migration a no-op: libakstdlib reserves no consumer range, so an application
may allocate from AKERR_FIRST_CONSUMER_STATUS without coordinating with it,
and every status this library raises is inside the reserved band with a name
actually registered -- an unnamed one degrades to "Unknown Error" in every
later stack trace, which nothing else would notice. It exercises the new
ownership enforcement too, so the "reserves nothing" assertion cannot pass
vacuously.
ctest 13/13, ASan+UBSan 13/13, coverage 15/15 at 90/40, mutation 89.6%
(155/173, unchanged). Also verified out of tree: the #error fires as the
first diagnostic against a stale akerror.h, pkg-config refuses akerror
0.9.0, and an external find_package(akstdlib) consumer builds and runs
against a temp-prefix install.
