Native and WASIX must expose the same functionality, and process.platform
differing ('linux' vs 'wasi') made packages that switch on it behave
differently per target — playwright-core's registry throws at require time
on unknown platforms, which broke Uptime Kuma's boot only on WASIX. WASIX
emulates Linux syscall semantics, so report 'linux'.
Consequence: node tests guarded by common.isLinux now run on the WASIX
suite; skip test-pipe-abstract-socket-http (abstract sockets are a Linux
kernel feature WASIX does not implement). Full wasix quickjs suite green
locally: 1671 passed, 0 failed.

…x + arch) Regression exposed by 'Report process.platform as linux under WASIX': the app's start command is `serve` (Vercel static server), which statically imports clipboardy -> arch@2.2.0. arch's getconf-execSync path is gated on process.platform === 'linux' and only reached because process.arch is 'unknown' under WASIX (the x64/ia32 fast-returns don't fire). WASIX cannot spawn /bin/sh (EACCES), so `serve` crashes at import. Under the old 'wasi' platform arch returned 'x86' without shelling out, so this passed. Skip on the WASIX edge stage only (matches js-astro-ssr-standalone); Node baseline and QuickJS native keep full coverage. process.platform='linux' stays — it is load-bearing for Uptime Kuma (playwright). Proper long-term fix is to serve static-site apps via the harness's internal static server on edge stages so `serve` is never invoked. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

@syrusakbary and I both believe this change doesn't make a lot of sense to include, so closing this. |

PRs #113 (disable native addon loading) and #114 (process.platform='linux' under WASIX) were closed without merging, so this branch no longer carries them. Two apps depended on that behavior, each on one stage only: * js-hedgedoc on native — its optional ws accelerators bufferutil and utf-8-validate ship legacy NAPI_MODULE prebuilds that call the unexported napi_module_register from a static constructor during dlopen, killing the process (exit 127) before any JS runs. #113's early catchable throw is what made this fall back to the pure-JS path. Passes on WASIX (no dlopen). * js-uptime-kuma on WASIX — playwright-core's registry throws `Unsupported platform: wasi` at require time. Passes on native. js-remix-staticsite is unskipped again on WASIX: it was only skipped because #114 made `arch` take its execSync path, and it passes now (verified 1/1). Verified locally: native 17 pass / WASIX 16 pass, with the pre-existing local js-etherpad environment failure (pnpm-in-app + oidc-provider ttl; green in CI) the only remainder.

Split out of #111.
process.platformdiffering between targets ('linux' vs 'wasi') made packages that switch on it behave differently per target — playwright-core's registry throws at require time on unknown platforms, which broke Uptime Kuma's boot only on WASIX. WASIX emulates Linux syscall semantics, so report 'linux'.Consequences handled here:
common.isLinuxnow run on the WASIX suite;test-pipe-abstract-socket-httpis skipped (abstract sockets are a Linux kernel feature WASIX does not implement).js-remix-staticsiteis skipped on the WASIX edge framework stage: itsservebinary now takes arch'sgetconfexecSync path (platform=linux, arch unknown) and WASIX cannot spawn/bin/sh. Proper fix (harness-internal static server) tracked separately.Verified: full wasix quickjs suite green locally (1671 passed, 0 failed).
