feat(workers): self-healing worker pool + deferred-resolution observability (#1741) (#1947)
* fix(workers): fail fast instead of silently degrading on worker-pool startup failure (#1741) When an explicitly-sized worker pool (--workers <N>) fails to start because every worker crashes during top-of-script init, the parse phase used to log a swallowed `logger.warn` and silently fall back to the ~10x slower sequential parser. In #1741 (rc99) that turned a worker-startup regression into a 123-minute "stuck" parse with no explanation. This change: - Surfaces the real crash: the pool now spawns workers with `{ stderr: true }`, tees + captures each worker's stderr, and attaches the tail to its readiness-failure messages (propagated via WorkerPoolInitializationError.readinessFailures). "did not report ready" now carries the underlying native-binding/import error. - Gates the fallback: when --workers was explicit and fallback was not opted into, a total startup failure throws an actionable error instead of degrading. Auto-sized pools still fall back, but loudly (logger.error + progress warning). New --allow-sequential-fallback flag (+ i18n) opts back in. - Adds env-gated worker bootstrap-stage logging (GITNEXUS_WORKER_BOOTSTRAP / --verbose): imports+grammars loaded -> ready sent -> first task received, so a slow/crashing startup is diagnosable. Tests: all-workers-failed gating (fatal vs loud degrade), stderr surfacing, and the updated lazy-cache fallback contract (opt-in flag + fail-fast). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * feat(ingestion): always-on slow-file watchdog for deferred call resolution (#1741) The original #1741 symptom is a run that appears stuck at "Resolving calls (all chunks)... (9000/18066 files)" — the progress bar freezes inside a single file's call resolution and nothing reaches the log. Rich per-file deferred diagnostics already exist, but only behind --verbose / GITNEXUS_PROFILE_DEFERRED, so a plain `analyze` run gives the user a frozen bar and silence. Add an always-on (not verbose-gated) per-file watchdog in processCallsFromExtracted: when a single file's call resolution exceeds alwaysOnSlowFileWarnMs() (default 15s, override GITNEXUS_SLOW_FILE_WARN_MS, 0 disables) it emits a throttled logger.warn naming the culprit file and the files-resolved-so-far — turning the silent stall into one actionable line. Throttled (>=30s between warnings) so a genuinely slow repo can't storm the log. The watchdog is observation-only; resolution behavior is unchanged. Note: deliberately did NOT add a heritage child x parent product cap — the name lookups are O(1) (type-registry Map.get) and the product is bounded, so the heritage build is not the bottleneck; a cap would risk dropping real edges for no measured gain. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test(ingestion): worker-vs-sequential parity guard for binding/edge collapse (#1741) rc99 produced almost no bindings/edges (13 bindings vs rc91's 106,305) because a worker-path failure left extracted results unmerged while the run still reported success. Rather than an arbitrary "implausibly low" runtime threshold (which false-positives on legitimately low-binding repos/languages), pin the invariant directly: for the same repo, worker mode and sequential mode must produce the same graph. The test runs the ts-simple cross-file fixture through worker mode (workerPoolSize + lowered threshold) and sequential mode (skipWorkers), and asserts: usedWorkerPool is true/false respectively (guards the test itself against a silent fallback masking divergence), identical CALLS/IMPORTS/DEFINES/ HAS_METHOD edge sets and Class/Function/Method defs, and non-zero CALLS/IMPORTS (the rc99 collapse signature). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(workers): arm fail-fast for env-sized pools + fix watchdog /0 denominator (#1741) Addresses two review findings on the #1741 worker-startup PR: - Fail-fast gate missed the env channel. `explicitWorkers` keyed only off the `--workers` flag, so a pool sized via `GITNEXUS_WORKER_POOL_SIZE` (with no `--workers`) silently degraded to sequential on a total worker-startup crash — reproducing the original #1741 symptom for env-channel operators. The gate now arms on a non-zero size from either channel, via a single-source `envWorkerPoolSize()` helper exported from worker-pool.ts (also rewired through resolveAutoPoolSize). The fatal message now names the channel actually used instead of "--workers undefined". - Always-on slow-file watchdog printed "Resolved N/0 files". `resolvedTotal` was pre-counted only on the profile path, but the watchdog reads it on every run, so a plain `analyze` showed a bogus /0 denominator on exactly the unprofiled hang the watchdog exists to explain. Pre-count now runs whenever its result is read (profile path OR watchdog active). Tests: strengthened the watchdog test to assert "1/1" (not "/0"); added env-channel fail-fast/degrade cases and made the gating suite hermetic against an ambient GITNEXUS_WORKER_POOL_SIZE. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * feat(workers): self-healing worker pool replaces the fail-fast flag (#1741) Replaces the interim --allow-sequential-fallback flag with automatic, bounded self-healing in the worker pool — industry-standard supervision (OTP restart-intensity, systemd StartLimit, circuit-breaker, AWS jittered backoff) translated to the Node worker_threads pool. worker-pool.ts — bounded startup self-heal (the missing layer): - A worker that crashes during top-of-script init is now RETRIED with capped, full-jitter backoff (BASE 250ms, CAP 2s) up to a small per-slot budget, so a transient blip heals itself with no operator action. The prior code dropped an unready initial slot on its first crash. - A DETERMINISTIC crash-loop (>=2 fresh workers crash with the same normalized signature before any reaches ready — the #1741 missing native-binding case) is detected and short-circuited, so the pool gives up in ~1s instead of burning every slot's budget. Correctness rests on the STRUCTURAL signal (zero workers ever ready + budget exhausted), so a missed signature only costs a few seconds, never a misfire; even a stderr-less crash groups via its normalized "exited with code N" message. - Backoff sleeps are cancellable (unref'd timer + abort on terminate), so terminate() can't be wedged for the backoff duration. - WorkerPoolInitializationError now carries a crashClass for an accurate, flag-free message. The runtime respawn/breaker path is unchanged. parse-impl.ts — collapse to automatic fail-fast: - handleWorkerStartupFailure always logs the real cause then THROWS with the captured crash + `--workers 0` as the explicit sequential escape. No more degrade branch; no dependence on how the pool was sized. This is reached only after the bounded self-heal is exhausted, so it can't resurrect the #1741 silent 123-minute sequential grind. Construction failure (broken install) also fails fast instead of degrading silently. Removed --allow-sequential-fallback end to end (CLI, run-analyze, pipeline, i18n). --workers 0 remains the explicit "parse sequentially" path; one flag removed, none added. Grounded in a research+critique pass; the critique's hazards (N-parallel race, empty-stderr timing, non-cancellable sleep, runtime-breaker regression) are addressed or scoped out by design. Tests: startup self-heal (transient recovers; deterministic fails fast without burning the budget); gating test rewritten to the fail-fast-always contract; obsolete degrade test removed. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(workers): ref + cancel startup backoff so transient retries aren't dropped (#1741 U1) abortableSleep unref'd its backoff timer, so a transient startup retry could be silently dropped if that timer was the last ref'd handle on the event loop — the process could exit mid-recovery. Keep the timer ref'd (a pending retry is necessary work) and register a cancel fn in a pool-scoped set; terminate() now clears pending backoffs so it can't be wedged for the backoff cap. A normally fired timer self-deregisters (clear-on-settle), so no timer lingers after a slot's retry loop exits. Exposes pendingStartupTimers in getStats. Tests: terminate-during-backoff cancels + spawns nothing after (R2); the recovery test now asserts no startup timer lingers after settle (R1). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(workers): route GITNEXUS_WORKER_POOL_SIZE=0 to sequential, not a phantom fail-fast (#1741 U2) env=0 (no --workers) built a size-0 pool that threw a fabricated "retry budget exhausted / native binding" crash. The shouldUseWorkers gate now routes env=0 to the sequential path before pool construction — but only when no explicit --workers <N> was given, so an explicit positive size wins over an ambient env=0. The route emits one log line so the undocumented (possibly accidental) env=0 case is observable instead of a silent degrade. envWorkerPoolSize is un-exported (module-internal sizing reader); a new workerPoolDisabledByEnv() predicate serves the gate. Empty/whitespace env is now treated as unset (auto formula), not 0 — an empty assignment is an accident, not a request for zero workers. Reattached the detached resolveAutoPoolSize JSDoc and corrected the stale docstring. Tests: env=0 → sequential (no spawn); explicit --workers wins over env=0; workerPoolDisabledByEnv unit (0=true, positive/empty/invalid=false); getStats shape updated for pendingStartupTimers. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(workers): make deterministic crash-loop detection conservative (#1741 U3) The old tally counted crash EVENTS in a shared signature->count map, so a simultaneous transient crash storm (e.g. spawn EAGAIN under fork pressure) or a single slot crashing identically twice falsely tripped "deterministic" and hard-aborted work that would have self-healed. Replace it: a crash counts toward deterministic only after its signature REPRODUCES across a respawn on the same slot, and the short-circuit fires once >=2 distinct slots reproduced (or 1 for a size-1 pool). Every slot now gets >=1 self-heal attempt before any short-circuit; the structural budget floor still bounds the worst case. crashSignature now also collapses Windows backslash paths and bare (no-0x) hex runs so the fast-path fires on those platforms; exported for unit testing. Tests: simultaneous storm self-heals (the discriminator vs an attempt-0 rule); distinct-per-attempt crashes classify transient-exhausted; single-slot reproduction classifies deterministic; crashSignature normalization unit. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(workers): class-aware startup failure hint + reattach detached JSDoc (#1741 U4) The "often a missing/broken native binding" hint was appended to every failure class, including a pool *construction* failure where no worker ever ran (a missing build / bad worker path). Make the hint class-aware: keep it for the readiness/init classes, use a construction-specific hint otherwise, and surface the construction error (e.g. "Worker script not found: …") verbatim. Reattach the waitForWorkerReady JSDoc that the stderr-capture block had detached from its function. (The abortableSleep docstring was already corrected in U1.) Tests: construction message surfaces the real error + drops the native-binding guess; deterministic/transient messages keep the hint (regression guard).

feat(ingestion): resolve FastAPI include_router(prefix=...) cross-file routes (#1877)
* feat(ingestion): resolve FastAPI include_router(prefix=...) cross-file routes
FastAPI sub-route files declare paths via @router.<verb> while the entry
file mounts the router with app.include_router(<router>, prefix='/x').
Previously both the ingestion-layer Route graph nodes and the group-layer
ExtractedContract URLs lost the cross-file prefix, breaking provider <->
consumer matching.
Ingestion layer:
- parse-worker emits routerIncludes / routerImports + decoratorReceiver
- parsing-processor / parse-impl thread the new fields and aggregate
prefixesByModule across chunks; decorator routes whose receiver is
'router' are duplicated once per matching prefix
- routes.ts joins prefix via normalizeExtractedRoutePath
Group layer:
- HttpLanguagePlugin gains an optional prepareRepo() pre-pass and a
repoContext arg to scan(); python.ts builds prefixesByModule and
falls back to the bare path when no entry matches
- http-route-extractor caches one repoContext per plugin
Tests:
- 3 new http-route-extractor cases (attr / named-import / no-prefix)
- ParseWorkerResult literals in 3 test files updated to the new shape
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
* fix(ingestion,group): address PR #1877 review — relative imports, cross-package collisions, host names, ingestion tests
Follow-ups to the FastAPI `include_router(prefix=...)` cross-file fix
based on PR #1877's automated production-readiness review. Three
correctness gaps and one test coverage gap addressed:
1. Relative-import support in the worker regex (FINDING 2)
`FROM_IMPORT_ROUTER_RE` now accepts module paths starting with a
`.` (e.g. `from .calls import router as calls_router`). The
previous `[A-Za-z_][\w.]*` rejected leading dots and silently
dropped every relative-import Shape-B include — a real pattern
from the PR description's own motivating example. The matching
helpers now strip leading dots before keying so absolute and
relative imports collapse to the same module key.
2. Cross-package same-name module collisions (FINDING 3)
Two-tier module keying replaces the previous basename-only key:
• short key — `users` (file basename without `.py`)
• long key — `api/users` (parent dir + stem)
`prefixesByLongKey` is consulted first and only falls back to
`prefixesByShortKey` when no long-key match is available. Both
the ingestion pipeline (parse-impl.ts) and the group extractor
(http-patterns/python.ts) carry the same scheme so the graph
nodes and HTTP contracts agree on which prefix applies.
New protocol field `ExtractedRouterModuleAlias` (parse-worker →
parsing-processor → parse-impl) lets Shape-A
`<host>.include_router(<mod>.router, prefix='/x')` calls promote
to a long key when the same file imports `<mod>` via
`from <pkg> import <mod>`. Without this, `api/users.py` and
`admin/users.py` collided on the basename `users` and the admin
file's routes inherited the `/users` prefix that was only meant
for `api/users.py`.
3. Non-`app` host variable names (FINDING 4)
The group-layer `INCLUDE_ROUTER_*_PATTERNS` queries pinned the
host identifier to the literal `"app"` and dropped every
`application = FastAPI()` / `api = FastAPI()` pattern — the
constraint was redundant given that the call shape
(`include_router` invoked with a router argument and a
`prefix=` keyword) is already specific enough. The pin is
removed; the ingestion regex was already unrestricted.
4. Ingestion-layer regression tests (FINDING 1)
The previous PR added group-layer tests
(`http-route-extractor.test.ts`) but zero in-tree tests for the
ingestion path. Two new suites pin the
worker → parse-impl → routes flow:
- `test/unit/fastapi-router-bindings.test.ts` (23 cases):
`extractFastAPIRouterBindings()` is split into a stand-alone
module so it can be unit-tested without booting a worker
thread, then pinned for regex shape, two-tier key emission,
relative-import support, and negative cases.
- `test/integration/fastapi-prefix-pipeline.test.ts` (5 cases)
plus `test/fixtures/fastapi-prefix-app/` — runs the full
`runPipelineFromRepo()` against a realistic multi-package
fixture (containing both `api/users.py` and `admin/users.py`)
and inspects the resulting `Route` graph nodes for cross-file
prefix joining and absence of cross-package bleed.
Verification
- `npx tsc --noEmit`: pass
- PR-touched test suites (6 files / 117 cases): all green
- `npx prettier --check`: pass on touched files
- `npx eslint`: 0 errors on touched files
Cache / compatibility
The new `routerModuleAliases?` field on `ParseWorkerResult` and
`routerModuleAliases` on `WorkerExtractedData` are optional /
guarded with `?? []`, so historical parse-cache entries continue
to load without forced re-scan.

* refactor(ingestion): move fastapi-router-bindings out of workers/ — pure module, not a worker
Addresses @magyargergo's `CHANGES_REQUESTED` review on PR #1877:
> Sorry I just found that we are introducing a new worker in the PR.
`gitnexus/src/core/ingestion/workers/fastapi-router-bindings.ts` was a
**pure-function module** — it never imported `worker_threads` or
`parentPort`, never spawned a worker, and was never registered as a
worker entry. It was placed in `workers/` purely because it was split
out of `workers/parse-worker.ts` to make its functions unit-testable
without booting a worker thread (parse-worker is itself the worker
entry and cannot be loaded from the main thread).
To remove the misleading directory placement:
• The implementation moves to
`gitnexus/src/core/ingestion/route-extractors/fastapi-router-bindings.ts`,
alongside the other framework-specific route extractors (`expo`,
`nextjs`, `php`, `laravel`, `middleware`, `response-shapes`).
• `workers/parse-worker.ts` keeps a thin re-export so the worker
entry can keep using `extractFastAPIRouterBindings` directly. The
re-export now carries an explicit comment stating that the imported
file is **not** a worker and that the `workers/` directory
deliberately hosts only true worker entries (`parse-worker.ts`,
`worker-pool.ts`, `quarantine.ts`).
• The new file's leading docstring opens with "NOT A WORKER" and
explains why it exists where it does.
• The unit test (`test/unit/fastapi-router-bindings.test.ts`) is
updated to import from the new path.
No behaviour change. The function body, signatures, and exported types
are identical.
Verification
• `npx tsc --noEmit`: pass
• `npx tsc` (dist rebuild): pass
• `test/unit/fastapi-router-bindings.test.ts` (23 cases): all green
• `test/integration/fastapi-prefix-pipeline.test.ts` (5 cases): all green
• `test/unit/group/http-route-extractor.test.ts` (63 cases): all green
• `npx prettier --check` on touched files: pass
• `npx eslint` on touched files: 0 errors
Refs PR #1877.
* refactor(ingestion): drop parse-worker re-exports; consumers import router types directly from route-extractors
Addresses @magyargergo's two remaining review comments on PR #1877:
1. **`gitnexus/src/core/ingestion/workers/parse-worker.ts:247`** —
"Can you please remove them and update the call sites?"
The `export type { ExtractedRouterInclude, ExtractedRouterImport,
ExtractedRouterModuleAlias } from '../route-extractors/...'` block
in parse-worker.ts is gone. The remaining `import type {…}` is
purely local — used only to type the corresponding fields on
`ParseWorkerResult` below — and the leading comment now says so
explicitly ("this file does NOT re-export them"). The
`extractFastAPIRouterBindings` symbol is also no longer re-exported
from parse-worker.ts; it's still imported here so the worker entry
can call it per file, but downstream consumers must reach it via
`route-extractors/fastapi-router-bindings` directly.
Call sites updated:
- `gitnexus/src/core/ingestion/parsing-processor.ts`
- `gitnexus/src/core/ingestion/pipeline-phases/parse-impl.ts`
Both files now `import type { ExtractedRouterInclude,
ExtractedRouterImport, ExtractedRouterModuleAlias }` directly from
`route-extractors/fastapi-router-bindings.js`. The worker types
they still need (`ParseWorkerResult`, `ExtractedToolDef`, etc.)
keep coming from `workers/parse-worker.js`.
The unit + integration tests already imported from the new path,
so no test changes were required.
2. **`gitnexus/src/core/ingestion/parsing-processor.ts:168`** —
suggested simplification:
for (const item of result.routerIncludes ?? []) allRouterIncludes.push(item);
for (const item of result.routerImports ?? []) allRouterImports.push(item);
for (const item of result.routerModuleAliases ?? []) allRouterModuleAliases.push(item);
Applied verbatim. Replaces the previous `if (result.…) for …`
guards. The cache-compat semantics are unchanged — historical
parse-cache entries that lack these fields still load cleanly,
the new form just spells the fallback inline.
No behavior change, no tests touched, no public API change.
Verification
• `npx tsc --noEmit`: pass
• `npx tsc` (dist rebuild): pass
• PR-touched test suites (6 files / 117 cases): all green
• `npx prettier --check` on touched files: pass
• `npx eslint` on touched files: 0 errors
Refs PR #1877.
* refactor(ingestion): hoist fastapi-router-bindings type imports to top of parse-worker.ts
Move the `import type { ExtractedRouterInclude, ExtractedRouterImport,
ExtractedRouterModuleAlias }` block to the top of the file with the
other type imports, and drop the comment that previously sat next to
ExtractedDecoratorRoute.

fix(analyze): prevent cache-hit native workers from aborting (#1751)
* fix(analyze): prevent cache-hit native workers from aborting Delay parse worker startup until a cache miss requires it, fall back to sequential parsing when initial worker readiness fails, and preserve analyzer diagnostics/progress when heap respawn captures child output. Constraint: Node 25 and tree-sitter/N-API worker initialization can abort before ready, while warm-cache analysis should not start workers at all. Rejected: Treating status-134/SIGABRT as heap OOM unconditionally | native worker aborts require distinct recovery guidance and stderr/stdout evidence. Rejected: cli-progress noTTYOutput for respawn progress | it appends newline frames instead of preserving one-line redraw UX. Confidence: high Scope-risk: moderate Directive: Keep parse-worker creation behind confirmed cache misses and preserve TTY-style progress when respawn pipes stderr for crash classification. Tested: GitNexus impact analysis for ensureHeap, runChunkedParseAndResolve, createWorkerPool, WorkerPool, walkRepositoryPaths; GitNexus detect_changes scoped to staged worktree; targeted vitest for analyze respawn, parse lazy cache, filesystem walker, worker pool; npx tsc --noEmit; npm run build; NODE_OPTIONS='--max-old-space-size=8192' npm test. Not-tested: Windows terminal rendering and published npm package install path. * ci(docker): tolerate slower arm64 TypeScript builds Docker PR builds run gitnexus prepare under QEMU for linux/arm64, where the fixed 120s TypeScript timeout can kill otherwise healthy builds. Increase the default timeout and allow GITNEXUS_BUILD_TIMEOUT_MS to tune slower environments without changing the build steps. Constraint: PR #1751 Docker Build & Push gitnexus failed with spawnSync /bin/sh ETIMEDOUT while running node_modules/.bin/tsc in scripts/build.js.\nRejected: Rerunning CI only | the failure was the build script's deterministic timeout boundary under arm64 emulation, not a code assertion.\nConfidence: high\nScope-risk: narrow\nDirective: Keep build timeout changes in scripts/build.js configurable; do not hide real compiler failures, only allow slower successful compiles to finish.\nTested: GitNexus impact for gitnexus/scripts/build.js reported LOW; gitnexus detect_changes reported 1 changed file, 0 affected processes, low risk; git diff --check; gitnexus npm run build.\nNot-tested: GitHub Docker arm64 build rerun before pushing; local Docker multi-platform build under QEMU. * fix(analyze): truncate respawn progress safely Preserve complete ANSI escape sequences and grapheme boundaries when the respawn progress terminal shim truncates wrapped output, so the shim does not emit dangling escape bytes or split surrogate pairs while keeping raw writes untouched. Constraint: Claude review on PR #1751 flagged `s.slice(0, width)` in createAnsiPipeTerminal.write() as a latent terminal-corruption risk. Rejected: Adding a display-width dependency | a local helper is sufficient for this narrow respawn terminal shim and avoids new dependency churn. Rejected: Changing silent status-134 classification | current tests already document the output-less 134 fallback as heap guidance. Confidence: high Scope-risk: narrow Directive: Keep respawn terminal writes ANSI-aware and preserve rawWrite bypass semantics for callers that intentionally write control sequences. Tested: GitNexus impact for createAnsiPipeTerminal reported LOW; GitNexus detect_changes reported 2 changed files, 3 affected processes, medium risk; targeted vitest for analyze respawn progress and heap respawn; gitnexus npx tsc --noEmit; prettier check for changed files; eslint for changed files. Not-tested: Full npm test suite; manual terminal rendering on Windows. --------- Co-authored-by: wangxc <wangxc_a_bj@si-tech.com.cn> |
