* test(infra): retry recursive temp-dir removal instead of failing a shard on ENOTEMPTY (#11966)
Two shards on release/v3.8.51 went red in one day with the same signature —
"ENOTEMPTY, Directory not empty: /tmp/omniroute-<test>-XXXXXX" — from
combo-same-provider-cascade (Unit Tests fast-path 4/4, on a PR that touches only
.github/) and auth-policy-embeddings-webfetch-7785 (the 20k-test TIA step). Both pass
alone and on re-run: the cleanup races something still writing into the directory
(SQLite WAL/-shm checkpoint, a worker, the backup) and under a loaded hosted runner
the window opens. 1154 test files do their own cleanup with
fs.rmSync(dir, { recursive: true, force: true }); 57 already asked for retries.
One-shot codemod (scripts/ad-hoc/codemod-rm-maxretries.mjs, kept for the record):
every rm / rmSync / rmdirSync option object with `recursive: true` and no
`maxRetries` gains `maxRetries: 5, retryDelay: 100` — Node itself then retries
ENOTEMPTY/EBUSY/EPERM for up to ~0.5 s before giving up. 2243 call sites in 1292
files under tests/, the shared tests/_setup/isolateDataDir.ts exit hook included.
Only the option object changes: no call site, assertion or import is touched.
Validation: prettier and ESLint (with the frozen suppressions) clean on all 1292
files; a random 20-file sample runs green (quota-redis-store hangs identically on
the untouched tree — it needs a Redis on localhost, an environment matter). The
four unit shards on this PR are the full run.
* fix(quality): let check-forgotten-sibling-tests read a 1,000-file diff
The gate shells out to `git diff` through execFileSync with Node's default 1 MB
maxBuffer; the 1,292-file codemod in this PR is the first diff large enough to
overflow it, and the gate died with `spawnSync git ENOBUFS` before comparing
anything. 64 MB is far above any real PR and costs nothing when unused.
Validated on a 2-PR combined board: 158/158 across the drain's 17 focused test files (incl. integration qdrant-routes), typecheck:core + dashboard-typecheck clean, env-doc-sync, mutation-test-coverage, cli-i18n, file-size, changelog-integrity all green. Every red discriminated per-item as stale-test (contract intentionally moved, citing the origin PR) or real bug (fixed, never masked) across 3 base-advance waves (#9985): stryker registration, i18n gaps (health.* namespace mismatch + pt-BR parity), combo-token-window pins (872K), CLI catalog counts (prime-agent), the isComboStep single-target reasoning-transport-fallback regression, container-guard hermeticity, and 26 unsuppressed ESLint errors from the wave (typed qdrant adapter, import trim, justified disable with precedent). Drains the accumulated base-red cluster.
