From 2d49dfa035d3fb48d0ecc3189d78a4ceb8066024 Mon Sep 17 00:00:00 2001 From: kilyanni Date: Sun, 2 Aug 2026 12:30:09 +0200 Subject: [PATCH 01/26] toolchain: run shebanged wasm files directly under wasmer A wasm module prefixed with `#!/path/to/wasix-run` becomes a file the kernel can exec AND wasmer can load: the vendored wasmer-wasm-shebang.patch skips a leading shebang line when loading a module. wasix-run is the trampoline that line points at: a wasmer-free stub that resolves the runtime from WASIX_WASMER at exec time (so it can be baked into build artifacts without putting the fast-moving wasmer input into their closures), forwards the environment (whole-environment mode via WASIX_RUN_ENV_ALL for the test harness, a small allowlist otherwise; empty and whitespace-only values are skipped since wasmer's CLI rejects them), and mounts the working tree.

One compile, shared with the shipped artifact; a runtime bump later re-runs tests without rebuilding anything.

Wiring: libraries attach the check (or, without a suite, a generic link-smoke) as passthru.tests on every supported profile; wheels re-run their installCheckPhase against the installed wheel, with declared check inputs carried across the cross gate via a passthru stash (wasixDeclaredCheckInputs) that package files can REPLACE when the inherited list cannot run in the guest; shipped CLIs keep curated suites plus a liveness smoke; the python dependency closure gets import tests; rust gets a cargo-test handoff (build once, exnref-translate, run under wasmer).

Restored; diagnose the psycopg/pillow cases + on their own evidence rather than assuming one root. +- Fix: inspect the failing dylibs' import/export sections (wasmer inspect) + the way httptools was diagnosed; the pattern may again be a **wasm**-guarded + embedder path in the vendored library rather than a toolchain bug. ### no default `TERM` 🔴 - wasmer starts processes with `TERM` unset (verified); terminal programs degrade.

Not a wasix or wasmer defect: nixpkgs' cpython sets + `ac_cv_x87_double_rounding=yes` for EVERY cross build + (pkgs/development/interpreters/python/cpython/default.nix). x87's 80-bit + registers are what cause double rounding, and wasm32 has no x87, only strict + IEEE 754 binary64. With it set, `pycore_pymath.h` defines + `_PY_SHORT_FLOAT_REPR 0`, CPython drops `Python/dtoa.c` (Gay's correctly + rounded shortest repr) and falls back to `%.17g`. +- Fixed: `overlay/packages/python3/package.nix` appends + `ac_cv_x87_double_rounding=no` to configureFlags (configure's command-line + assignments beat the environment, and the last one wins). Verified under + wasmer: `float_repr_style = short`, `repr(1.1) == '1.1'`.

Small suites (six, idna, numpy) exit 0. +- Workaround: the `wasix_hard_exit` pytest plugin (`pkgs/emulated-check.nix`) + calls `os._exit` with pytest's own exit status after the summary is + written, so interpreter shutdown never runs (same plugin as the shutdown-GC + trap above). +- Fix: find what fails in CPython's shutdown path under wasix (thread join, + atexit, or fd close) and make it exit cleanly. + +### `dup()` of stderr fails EOVERFLOW 🟡 + +- `faulthandler.enable()` in CPython dies with errno 61, EOVERFLOW (verified + running pytest on the python webc); it dups the stderr fd.

NetworkError gains unreachable variants mapped end to end. epoll-stale-handler-deadlock: re-registering a pipe/socketpair fd in a new epoll after the old one closed dropped the stale handler's join guards while the pipe locks were held, deadlocking the guest (python's selectors does exactly this); replaced handlers are dropped only after every lock is released, and EPOLLOUT is primed for socketpair ends, which are always writable but never emit a writable transition. With those fixed (plus whole-env forwarding delivering NO_INTERNET), dnspython runs 1179 tests and pycurl 613 against its loopback fixtures; the TLS-over-loopback remainder is recorded in WASIX-TODO.md.

Caveats for + upstream: the socket arm's `set_handler` has the same stale-drop pattern, + and priming happens once per registration, so a second `epoll_wait` on the + same always-writable fd still reports nothing (true level-trigger needs the + drain path to re-poll readiness).

Nothing about the suite is restated; there is no per-package +harness config. + +**Build-once / run-many, one compile.** The package's own build captures its +test tree as a `check` output (`pkgs/lib/check-output.nix`, applied set-wide +through the stdenv adapter), so the suite is compiled by the same derivation +that produces the shipped artifact. A run-only derivation +(`pkgs/emulated-check.nix`) restores that tree, prepends a `#!wasix-run` +shebang to every executable wasm, and runs the package's real checkPhase with +the runtime present. wasmer is never a build input, so a wasmer bump re-runs +tests without recompiling. The restore relies on the sandbox build dir being +`/build` in both derivations, so baked absolute paths resolve. + +The shebang (plus `patches/wasmer-wasm-shebang.patch`, which makes the +runtime skip it when loading a module) is what lets every harness work +unmodified: ctest, automake recipes that exec `./prog` directly, meson test. +harfbuzz runs its meson tests through a per-package `exe_wrapper` in its own +cross file; the set-wide `mesonEmulatorHook` stays no-op'd deliberately, +because the stock hook also makes meson execute target binaries during +configure (`pkgs/overlay/default.nix`). + +Opting in and out: + +- C libraries: `doCheck` in the package file; `doCheck = false` (with a + reason) opts out. +- Wheels: `passthru.wasix.installCheck = true`/`false`.

As the previous comments indicate this is possible to do in +some situations, but the current logic is incomplete and has led to +miscompilations such as #98323 and #199910. One option would be to make +the logic more robust, but in lieu of that in the meantime the change +here is to completely disable stackification in these situations. This +provides at least a "known working" base to build on later and fixes the +known regressions around this. + +Closes #98323 +Closes #199910 + +Backport to LLVM 21.1.2.
