Three follow-ons to the stale-build report, all cases of an identity not
capturing something that changes the output.
The host PCM cache under <cache>/crafter.build/<target>-<march>/ is shared by
every crafter-build on the machine, and freshness was a per-file mtime
comparison. That cannot tell "this PCM is newer than my source" from "this PCM
was built from different sources that happen to be newer", so a package install
and a working checkout — or two checkouts of different versions — silently
compiled their project.cpp against each other's declarations. Invalidation now
keys on a stamp over the bytes of every module source, which also covers the
case one file's mtime never could: the cached PCMs import each other, so a
change to :Interface invalidates :Clang's PCM with Crafter.Build-Clang.cppm
untouched.
Project args ApplyStandardArgs does not itself interpret are now folded into
VariantId. Such a flag typically decides what gets compiled or bundled — the
report's example is --no-webgpu dropping entries from cfg.files — and without it
both settings shared one bin dir and interleaved their outputs there, leaving a
bundle matching neither. Sorted and deduplicated so flag order doesn't split the
cache, and inherited by test Configurations.
`crafter-build clean` removes the project's bin/ and build/ trees. It
deliberately does not load project.cpp: cleaning is most often reached when
something is already wrong, and a clean that first needs the project to compile
is useless exactly then.
The suite had only HelloWorld, which built and exited an empty exe. Add
in-process tests covering each public surface area users actually touch:
- StaticLib / ModuleInterface / DependencyLink — Build() against
fixtures for libraries, project-local module interfaces, and
cross-config module deps with link verification (runs the built exe).
- ShaderCompile — drives Shader::Compile directly, validates SPIR-V
magic + Check() idempotency.
- StandardArgs — covers --debug, --target=, --march=, --mtune=,
--lib/--shared promotions, and ArgQuery::Has / Get.
- TestRunnerSpec — FromSpec parse rules, ForTarget routing for host,
wasm32-wasip1, aarch64-linux-gnu (+ sysroot QEMU_LD_PREFIX),
i686 → qemu-i386 rewrite, mingw → wine on Linux hosts, FromEnv.
- VariantId — confirms type / debug / sysroot / defines / compileFlags /
target / march all perturb the cache key, plus PcmDir routing.
- WasiBrowserRuntime — calls EnableWasiBrowserRuntime, asserts the
three cfg.files entries get registered and index.html had its
template placeholder substituted.
- RunSingleTestExit — drives RunSingleTest against tiny sh scripts and
pins the documented exit-code mapping (0/77/non-zero) and the
Cmd-prefix runner path.
Closes#12.
