From 3be7ba6ee3841ab729f71f359598042160fa5e2a Mon Sep 17 00:00:00 2001 From: Sarah Fortune Date: Thu, 7 May 2026 14:59:24 -0700 Subject: [PATCH] ci+test: run check on windows and guard windows-only test behavior MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Run the check job on windows-latest in addition to ubuntu so the windows code paths (no O_NOFOLLOW, node fallbacks for fd-relative ops, ACL inspection) are exercised on every PR rather than only documented. Make the test suite pass on the new windows runner by addressing the platform-specific failures: - Long happy-path tests that mix supported (mkdir, write, read) and unsupported (stat, list, move, exists) operations are guarded with skipIf(process.platform === "win32") since the pinned filesystem helper throws "unsupported-platform" on win32 by design (src/pinned-python.ts). - Short focused tests where the unsupported operation is the whole point (pinned-python, pinned-write-fallback-coverage, write-boundary-bypass symlink-move) split into runIf(non-win32) and runIf(win32) tests, with the windows variant asserting unsupported-platform. - The expectFsSafeCode helper accepts unsupported-platform on windows; new expectedFsSafeCode helper substitutes for per-rejects.toMatchObject sites where the windows code differs from posix (e.g. path-alias / not-found returning unsupported-platform via the helper layer). - secure-file-reads test split into a posix happy-path runIf and a windows runIf that asserts permission-unverified, since ACL inspection has no portable equivalent on windows (src/secure-file.ts:177). - safeFileURLToPath test uses hardcoded platform-specific input/ output instead of building the URL via pathToFileURL+fileURLToPath so the assertion verifies the function directly. - Fix expandHomePrefix to normalize path separators by splitting via path.normalize + path.sep and rejoining via path.join. Apply the same segment-based check to resolveHomeRelativePath and resolveOsHomeRelativePath. Drop input.trim() — whitespace is a valid filename character on both platforms and env-var inputs are already trimmed upstream via normalizeOptionalString. - coverage-more's "normalizes empty temp names" decomposes the result with path.dirname/path.basename instead of regex-matching a path-separator literal. - extracted-helpers' path-helpers test builds its root with path.resolve so the drive letter is present on windows. - additional-boundary-bypass guards its "..\evil.txt" sanitizer assertion behind a non-win32 check (windows reserves "\" as a path separator and cannot have it in a filename). - coverage-more's sibling temp test guards just the posix file-mode assertion (stat.mode & 0o777 === 0o600), which has no analog on windows. The syncing behaviour the test actually targets still runs on both platforms. - Raise test/new-primitives.test.ts size budget to 1500 to accommodate the secure-file-reads test split. After: 253 passed, 1 failed, 66 skipped on windows-11-arm64. The single remaining failure is a separate library-side gap (a SAFE_REJECTED_SUSPICIOUS_WRITE_PAYLOADS payload resolves on windows instead of rejecting) and will be tracked in a follow-up.
