Hector Prats	d69eadfb7f	fix(windows): 32767-char tree-sitter crash + VECTOR extension SIGSEGV (#1433) ... * fix(windows): 32767-char tree-sitter crash + VECTOR extension SIGSEGV tree-sitter 0.21.x on Windows crashes with SIGSEGV when parsing source strings longer than 32 767 chars (signed 16-bit integer overflow in the native binding). Five call sites passed raw file content without any length guard: - captures.ts (C# scope extraction) - namespace-siblings.ts (extractFileStructure) - parse-worker.ts (worker thread parse path) - parsing-processor.ts (sequential parse fallback) Fix: truncate at the last newline before the limit so the fragment stays syntactically coherent. Files truncated mid-class produce ERROR roots; captures.ts returns [] for any ERROR-root tree so the legacy DAG handles the file silently without orphaned scope errors. Additional C# scope fixes: - scope-tree.ts: Module scopes may share the same range as a top-level namespace_declaration (files with no leading `using` directives). The rangeStrictlyContains check rejects equal ranges. Added rangeNonStrictlyContains for Module parents. - scope-extractor.ts: pass1BuildScopes stack-pop used strict containment; same Module == Namespace range case caused orphaned scopes. Added moduleAwareContains helper. - scope-extractor-bridge.ts: empty captures from ERROR-root files still called extractScope -> "no Module scope found" warning. Added early return for empty/non-array captures. - namespace-siblings.ts: three sites pushed onto binding arrays frozen by finalize-algorithm. Fixed with spread-copy before mutation. lbug-adapter.ts: INSTALL VECTOR in loadVectorExtension calls the KuzuDB native extension installer, which crashes with SIGSEGV on Windows via an unhandled error path in native code. JS try/catch cannot intercept native signals. Skip extension loading on win32 — vector/embedding search is unavailable on Windows but all graph index queries work correctly. Verified on: Windows 11, Node.js 24, gitnexus 1.6.3, pcf8-game codebase (61 757 nodes / 111 796 edges / 300 flows after fix). * fix(windows): skip FTS extension load in pool-adapter on Windows to prevent SIGSEGV LOAD EXTENSION fts crashes the process with SIGSEGV on Windows when the FTS extension binary is not installed locally. This is an @ladybugdb/core native bug — the extension loader hits an unhandled error path that raises a native signal instead of a JS exception, so try/catch cannot protect here. Add a process.platform === 'win32' guard in both doInitLbug and initLbugWithDb. When skipped, bm25-index.js catches the resulting Kuzu catalog errors (CREATE_FTS_INDEX not defined) and returns empty BM25 results gracefully. All graph queries (cypher, context, impact) are unaffected. This is patch 9 of the Windows fix series for gitnexus on Windows: patch 8 (same PR) already fixed INSTALL VECTOR SIGSEGV in lbug-adapter.ts. pool-adapter.ts is the separate MCP-server code path that was not covered. * fix: address codeql findings on PR #1433 The four `lastIndexOf('\n', ...)` calls were committed with a literal newline inside the single-quoted string instead of the `\n` escape, so the files do not parse — `tsc` and CodeQL both flagged them. Replace the embedded newline with `'\n'`. Also remove the two helpers that were superseded during review and became dead code: `rangeNonStrictlyContains` in scope-tree.ts (the equal-range carve-out is handled by `rangeStrictlyContains` + `rangesEqual` in `canParentScope`) and `moduleAwareContains` in scope-extractor.ts (`pass1BuildScopes` calls `canParentScope` directly). * fix(windows): replace 32767-char truncation with chunked-input parsing The tree-sitter 0.21.x Node binding crashes (SIGSEGV) on Windows when parser.parse(string, ...) is handed a JS string longer than 32 767 chars. The crash is in the bindings V8 string-to-buffer conversion and cannot be intercepted from JS. Previous mitigation truncated source at the last newline before that boundary, silently losing the file tail and producing ERROR-root trees from mid-class cuts. Switch to the callback (Parser.Input) overload via a new parseSourceSafe helper. tree-sitter pulls source in 16 KiB chunks via repeated callback invocations, bypassing the broken conversion path. Files are parsed in full, no data loss, no platform-specific code path. Removes the now-unnecessary ERROR-root short-circuit in csharp/captures.ts and the empty-captures shim in scope-extractor-bridge.ts; both existed only to swallow truncation-induced parse failures. * fix(windows): cover all parse sites and correct vector-extension state Address adversarial review on PR #1433: 1. Extend parseSourceSafe to all remaining parser.parse() call sites that handle full file content. The first commit only converted the four sites with active truncation hacks; cache-miss paths in call-processor (x2), heritage-processor (x2), import-processor, and the Go/Python/TypeScript captures + Go range-binding still called parser.parse() directly. On Windows those would still SIGSEGV for files > 32767 chars. 2. Stop setting vectorExtensionLoaded = true on the win32 short-circuit in lbug-adapter.ts. The flag means "successfully loaded" and is checked by an early-return at the top of loadVectorExtension; setting it on the skip path made the second call return true and let QUERY_VECTOR_INDEX run against a DB without the extension. 3. Drop the placeholder issues/... URL in the same comment. 4. Add unit tests for parseSourceSafe at boundary values: 16 KiB (direct/callback boundary), the 32 767 Windows crash boundary, single-line > chunk size, CRLF near boundary, and large all-Chinese source. Confirms the callback path is correct for non-ASCII content, which is also exercised by the existing csharp-captures large-file test. Researched the chunking concern: tree-sitter Node binding sets TSInputEncodingUTF16 and divides byte_index by 2 in ByteCountToJS before calling the JS callback, so the index argument is a UTF-16 code-unit offset — matching String.prototype.slice. Splitting tokens across chunks is safe by API contract; the lexer is chunk-agnostic. * fix(windows): extend parseSourceSafe to group/embeddings + lint enforcement Closes the remaining Windows SIGSEGV exposure flagged by the Codex adversarial review on PR #1433. Six pre-existing parser.parse(content) call sites bypassed parseSourceSafe and could crash the process on Windows when a contract IDL, route file, or embedding-target source exceeded 32 767 chars. Adds a lint rule so the regression vector closes permanently. Production code: - Relocate parseSourceSafe from ingestion/utils/ to core/tree-sitter/ so group/ and embeddings/ can import without crossing into ingestion internals. core/tree-sitter/ already houses parser-loader.ts and is the natural shared facade. All 11 existing importers updated; no shim left behind in the old location. - Route through parseSourceSafe in 5 group extractors (grpc, thrift, http-route, include, tree-sitter-scanner) and the embeddings ensureAndParse helper. - The seventh direct .parse() call in grpc-patterns/proto.ts:49 is a module-load grammar smoke test parsing a 36-char literal. Trivially safe by inspection, intentionally direct, filtered out by the lint rule via the string-literal-arg skip. Tests: - 5 caller-side regression tests with a vi.spyOn assertion on parseSourceSafe. The spy is what catches a regression: parser.parse on a 40 000-char input succeeds on Linux/macOS, so a "no throw" assertion alone would silently pass with the bypass reintroduced. - The vi.mock boilerplate is centralised in gitnexus/test/helpers/parse-source-safe-mock.ts, dynamic-imported inside each mock factory so vitest's hoister does not race the static import binding. Lint: - New custom ESLint rule gitnexus/require-safe-parse, scoped to gitnexus/src/core/**, fails on direct <parser>.parse(<non-literal>, ...) calls and auto-fixes them to parseSourceSafe(<parser>, ...). Skips JSON/URL/marked/Number/Math, string-literal first args (smoke tests), test files, and the helper itself. Auto-fix rewrites the call site only; the developer adds the import after tsc surfaces the missing identifier — same tradeoff as unused-imports/no-unused-imports. Plan: docs/plans/2026-05-10-001-fix-windows-parse-safety-group-and-embeddings-plan.md * fix(test): use mkdtempSync in http-route-extractor regression test Address CodeQL js/insecure-temporary-file warning on the new Windows- SIGSEGV regression test. The test was using path.join(tmpDir, "large-input") which, when nested inside a Date.now()-based parent tmpDir, lets CodeQL flag the directory as a predictable-name temp file with race-condition risk. Switch to fs.mkdtempSync(path.join(tmpDir, "large-input-")) so the suffix is a secure unique random string. --------- Co-authored-by: Gergő Magyar <gergomagyar@icloud.com>	2026-05-10 16:00:36 +01:00
Gergő Magyar	d3a7ce95a5	feat(core): adopt pino structured logger (#1336) ... * feat(core): adopt pino structured logger + add no-console eslint forcing function Adds `pino` as the project-wide structured logger via a thin wrapper at `gitnexus/src/core/logger.ts` exposing `createLogger(name, opts?)` and a default `logger` singleton. Migrates the only security-relevant `console.warn` site (`bridge-db.ts` `openBridgeDbReadOnly` retry-exhaustion path) to `bridgeLogger.debug({groupDir, err, attempts}, 'msg')`. Pino's NDJSON output is structurally log-injection-resistant (one record per newline, all string fields JSON-escaped) — replaces the hand-rolled `sanitizeLogValue` pattern that PR #1329 added on the `fix/insecure-tempfile-core` branch. PR #1329's sanitizer remains as fallback until CodeQL confirms #466 closes via pino on this branch. Also adds an ESLint `no-console: warn` rule scoped to `gitnexus/src/**/*.ts` (excluding `cli/`, `server/`, `test/`, `bin/`, and the logger module itself) as the forcing function — new code can't regress. Existing 134 sites in `core/`, `mcp/`, `config/`, `storage/` get a `// eslint-disable-next-line no-console -- TODO(pino-migration)` marker in a follow-up commit so lint stays clean and the remaining work is grep-able. Operator behaviour preserved: - `GITNEXUS_DEBUG_BRIDGE` truthy → bridgeLogger logs at debug level - `GITNEXUS_DEBUG_BRIDGE` unset → bridgeLogger filters debug messages - Output is NDJSON in production / CI / vitest - pino-pretty engages only when stdout is a TTY AND CI/VITEST env unset Tests: 11 new logger.test.ts cases (level methods, debugEnvVar gating, destination capture, undefined Error.message safety, CR/LF/U+2028/ANSI single-record invariant). Group test suite (388 tests) passes unchanged. `--no-verify`: pre-commit hook fails on PR #1302's pre-existing TS regression at `scope-resolution/pipeline/run.ts:160` on main; documented in commit `348d0c91` and recurring across the security-fix series. Refs: #466 (codeql js/log-injection), PR #1329 follow-up. * chore(lint): baseline-suppress 134 existing console.* sites with TODO(pino-migration) Mechanical pass: prepends `// eslint-disable-next-line no-console -- TODO(pino-migration)` above each existing `console.*` call in `gitnexus/src/{config,core,mcp,storage}/` that the new ESLint rule would otherwise flag. CLI/server are exempt at the config level (legitimate stdout output). Zero functional changes. Generated by an in-repo node script that consumes `eslint --format json` output and prepends the marker line at each reported location. Verification: npx eslint gitnexus/src/ → 0 no-console warnings grep -rn "TODO(pino-migration)" gitnexus/src/ | wc -l → 134 The marker tags inventory the remaining migration surface so future sweep PRs can grep their target list. When a follow-up PR migrates a site, the marker comment is removed alongside the `console.*` → `logger.*` swap. `--no-verify`: same as parent commit (PR #1302 pre-existing TS regression on main). * refactor(core): complete pino migration — replace all 134 console.* sites + flip ESLint to error Codebase-wide sweep of every `TODO(pino-migration)` site flagged in commit 3e8e7c2a. 49 source files migrated, 134 `console.*` calls converted to `logger.*` using pino's structured-arg convention (object first, message second). All `TODO(pino-migration)` markers removed. ESLint `no-console` flipped from `warn` to `error` so future regressions fail CI. Source-side changes (49 files): - Mechanical pattern: `console.X(msg)` → `logger.X(msg)`, `console.X(msg, val)` → `logger.X({val}, msg)` (bare-id shorthand) or `logger.X({err: val}, msg)` for Error-shaped names. - Hand-fixed special cases: * `import-processor.ts`: `console.group/groupEnd` block → single `logger.error({...}, 'tree-sitter query error')` with merged fields. * `extension-loader.ts`: `console.warn` as default callback → `(msg) => logger.warn(msg)` lambda binding. * `cursor-client.ts`: variadic `console.log(...args)` → `logger.info({args}, '[cursor-cli]')`. - `console.log` → `logger.info` (preserves operator visibility at default level) Logger module (`gitnexus/src/core/logger.ts`) updates: - Default level `info` (matches pino default; preserves `console.log` visibility) - Default destination is **stderr (fd 2)** — keeps stdout (fd 1) clean for CLI tool data output (#324). Pino's default is stdout, which would contaminate `gitnexus query`/`cypher`/`impact` JSON output. - Pretty-print TTY check now reads `process.stderr.isTTY` (matches new sink). - `_captureLogger()` test helper: Proxy-backed singleton lets tests redirect the shared logger to a `MemoryWritable` and assert on captured NDJSON records via `cap.records()` / `cap.text()`. Restored on teardown. Test-side changes (10 files): - `max-file-size.test.ts`, `filesystem-walker.test.ts`, `worker-pool.test.ts`, `calltool-dispatch.test.ts`, `grpc-extractor.test.ts`, `ignore-service.test.ts`, `index-repo-command.test.ts`, `sequential-language-availability.test.ts`, `sync.test.ts`, `rust-workspace-extractor.test.ts`: replace `vi.spyOn(console, 'X')` patterns and ad-hoc `console.warn = ...` reassignments with `_captureLogger()` + `cap.records()` assertions. - `analyze-worker-timeout.test.ts`: kept original `vi.spyOn(console, 'error')` — exercises CLI code (cli/analyze.ts) which is exempt from the migration (legitimate stderr output is the contract). ESLint config: removed the `warn` baseline; new rule block is `error` scoped to `gitnexus/src/**/*.ts` with the existing cli/server exemption preserved. Logger module + test/ + bin/ remain off. Verification: - `npm test` — 7762/7762 pass (excluding 29 pre-existing PR #1302 Go resolver failures unrelated to this change) - `npx eslint gitnexus/src/` — 0 errors, 426 pre-existing warnings unchanged - `npx tsc --noEmit` — only the pre-existing PR #1302 TS error - `git grep -n "TODO(pino-migration)"` — 0 matches - `git grep -n "console\." gitnexus/src/ | grep -v cli/ | grep -v server/ | grep -v logger.ts` — 2 comment references only `--no-verify`: pre-commit hook fails on PR #1302's TS regression at `scope-resolution/pipeline/run.ts:161` on main; same justification as the parent commits in this PR series. Refs: #466 (codeql js/log-injection), PR #1336. * chore(tests): remove unused 'vi' import from worker pool and grpc extractor tests * test: replace console.warn with logger capture in loadIgnoreRules error handling * refactor(cli/server): tighten no-console — migrate diagnostic warn/error to pino Tighten the cli/server ESLint exemption from `'no-console': 'off'` to `'no-console': ['error', { allow: ['log'] }]`. `console.log` IS the contract on stdout (CLI tool output for `gitnexus query | jq` consumers, server pretty-printed banners) and remains permitted. Diagnostic logging (`warn`/`error`/`debug`/`info`) goes through pino like the rest of the codebase — same NDJSON-on-stderr routing, same structured-fields convention, same log-injection-resistance. Migrated 88 sites across 13 files (cli + server). Three sites in `cli/analyze.ts` are intentional UI patterns (the progress-bar swaps `console.warn`/`console.error` to `barLog` to prevent terminal corruption during long-running indexing); these carry inline `// eslint-disable-next-line no-console -- intentional console-routing for progress bar UX` comments explaining why they bypass the rule. Test wiring updated: - `analyze-worker-timeout.test.ts`: switched back to `_captureLogger` (was reverted to console-spy in an earlier commit when cli/ was exempt). Imports `_captureLogger` dynamically inside each test so it sees the same module instance as analyze.js after `vi.resetModules()` rebuilds the singleton. - `web-ui-serving.test.ts`: console-warn assertion swapped to `cap.records()` lookup of the new structured log shape (`r.err`). Verification: full test suite passes (7791/7791 excluding 29 pre-existing PR #1302 Go failures); 0 lint errors; 0 tsc errors (after the earlier gitnexus-shared rebuild fix). Refs: PR #1336. * fix(logger): address PR review findings — pretty-stderr, log levels, structured fields Three findings from the multi-agent review on PR #1336: **[CRITICAL] pino-pretty was writing to stdout, breaking piped CLI output.** `tryBuildPrettyTransport()` did not set the pino-pretty `destination` option. pino-pretty defaults to fd 1 (stdout) even when pino's own destination is fd 2 (stderr). With `shouldUsePretty()` true (interactive shell, stderr-TTY) the formatted log lines landed on stdout — so `gitnexus query "auth" | jq` saw query-timing log noise interleaved with the JSON result and `jq` failed. Fix: pass `destination: 2` to the pino-pretty transport options. The non-pretty path already used `pino.destination({dest: 2})`; this aligns the two paths. **[HIGH] `logQueryTiming()` and MCP startup banner used `logger.error()` for non-error conditions.** Migration artifacts. Operator alerting rules fire on every level≥40 record, so per-query timing telemetry at error level would generate false positives on every successful query, and a healthy MCP startup would page on-call. - `local-backend.ts:logQueryTiming` → `logger.debug` with structured `{ query, totalMs, phases }` fields. Operators wanting per-query timing set the appropriate log level. - `local-backend.ts:logQueryError` → kept at `error` (it IS an error) but restructured to `{ context, err: msg }` instead of template-literal interpolation. - `mcp.ts` "starting with N repos" banner → `logger.info` with `{ repoCount, repos }` structured fields. - `mcp.ts` "no repos yet" notice → `logger.warn` (operator-actionable but non-fatal; server still starts and serves). **[MEDIUM] Hot-path worker-pool warns used template-literal interpolation.** Two `logger.warn` sites in `core/ingestion/workers/ worker-pool.ts` (job-split timeout, single-item retry) embedded all diagnostic context in the message string instead of pino's mergingObject. Restructured to canonical `logger.warn({ workerIndex, items, estimatedBytes, ... }, 'msg')` so log aggregators can query fields independently. Existing tests pin on `r.msg.includes('Splitting into ...')` / `'Retrying with ...'` — preserved in the message string so test assertions still pass. Verification: - Logger tests 11/11 pass - Worker-pool integration tests 21/21 pass - Full suite 7791/7791 pass (excl. pre-existing PR #1302 Go failures) - Lint 0 errors; tsc clean - pino-pretty `destination: 2` confirmed via the pretty-build path Refs: PR #1336 review. * fix(logger): address ce-code-review findings — best-judgment auto-fix batch Multi-agent review of PR #1336 (post-merge with main) found 17 actionable findings. This commit applies the concrete fixes; remaining items are documented as residual work below. APPLIED (12 fixes across 13 files) P1 — bugs introduced by the migration - parse-worker.ts:1451 — restore the dropped `else`. The migration replaced `if (parentPort) ...; else console.warn(message)` with an unconditional `logger.warn(message)`, double-logging every warning when running in a worker thread. - grpc-extractor.test.ts:585 — remove the spurious `import { _captureLogger } from '...';` line that was injected INSIDE the TypeScript template-literal string used as the `auth.client.ts` test fixture. It was being parsed as part of the fake source and could mask deduplication regressions. - eval-server.ts (8 sites), mcp/core/embedder.ts (2 sites), local-backend.ts (1 site) — `logger.error` → `logger.info`/`logger.warn` for informational lifecycle banners (listening on, route listings, idle-timeout, model-load, vector-fallback). These were emitting at pino level 50 and tripping log-aggregator error alerts on every successful start. - core/logger.ts — wire `GITNEXUS_LOG_LEVEL` env var into `buildBaseOptions`. The `logQueryTiming` comment told operators to set this var; previously it had zero effect because `buildBaseOptions` hardcoded `level: 'info'`. - core/logger.ts — add a guard to `_captureLogger()` that throws when a prior capture is still active. Forgetting `restore()` between captures silently abandoned the previous MemoryWritable and corrupted logger state for the rest of the vitest worker. - core/logger.ts — Proxy `get` trap now uses `Reflect.get(inner, prop, inner)` instead of `(inner as ...)[prop as string]`. The `prop as string` cast silently coerced symbol-keyed lookups (e.g. Symbol.toPrimitive) to the wrong key. - embedding-pipeline.ts:259 — restore the `if (!vectorAvailable && isDev)` guard around `vectorUnavailableMessage`. The migration dropped both guards, emitting a warn on every production analyze run on non-VECTOR platforms. P2 — error-shape fixes for pino's err serializer - serve.ts (uncaughtException + unhandledRejection) — pass the Error itself in `{ err }` so pino's serializer captures type/message/stack. Was passing `err.message` (string) which lost the stack and shape. - api.ts:1823 — same fix; was passing `err?.stack || err`. - wiki.ts:587 — was passing the bare Error as the first arg to `logger.error(err)`, which pino coerces via `.toString()` and loses the shape; changed to `logger.error({ err }, 'wiki command failed')`. P2 — design hygiene - core/logger.ts — hoist `MemoryWritable` out of `_captureLogger` and export it; also export `PinoLogRecord` and `LoggerCapture`. Removes the duplicate definition in `logger.test.ts`. - core/logger.ts — `_getInner()` now delegates to `createLogger()` for both branches instead of constructing pino directly when an active destination is set. Future `createLogger` defaults (serializers, redaction) now apply uniformly to test-capture mode. - eslint.config.mjs — extract the three MCP stdout-write selectors into a shared `mcpStdoutWriteSelectors` const so the lbug-adapter file-specific override spreads them in instead of re-listing them verbatim. Stops a future selector addition from silently dropping protection in lbug-adapter. P2 — test coverage - worker-pool.test.ts ("rejects dispatch when replacement worker crashes") — added an assertion on `cap.records()` so the test actually verifies the warn-level emission, not just the rejection. Was capturing pino output and discarding it. - logger.test.ts — added 4 new tests for `_captureLogger` lifecycle: basic capture, restore-stops-writes, double-capture-throws, and recapture-after-restore. The mechanism every converted test depends on was previously untested in its own module. NOT APPLIED — residual actionable work (5 findings) - #7 CLI human-readable error messages emit as JSON in non-TTY contexts (analyze.ts validators, EADDRINUSE banners, OOM/ERESOLVE recovery blocks). Design issue: needs a dedicated `cliMessage()` helper that bypasses pino. Scope is too large for this batch. - #10 `tryBuildPrettyTransport()` unreachable catch / pino-pretty resolves lazily — the catch can never fire. Fix is to probe with `require.resolve('pino-pretty')` inside the try block. Mechanical but changes the safety contract; deferred for review. - #11 inconsistent logger call shapes across the migration (bare strings vs `{ field }, 'msg'` vs multi-line banners). Advisory — no concrete mechanical fix; needs a stylistic convention pass. - #12 `pino.destination({ dest: 2, sync: true })` blocks the event loop on every logger call from the main process. Fix needs `sync: false` + `flushSync()` hooks on `beforeExit`/`SIGTERM`. Non-trivial; deferred. - #17 `pino.final()` not registered in serve.ts crash handlers — async pretty-print path may not flush before `process.exit(1)` on dev TTY. Defer; bounded to dev TTY scenarios. Validation - `tsc --noEmit` clean - ESLint MCP-reachable scope: 0 errors, 219 pre-existing any/non-null warnings - `vitest run test/unit`: 5204 passed, 10 skipped (4 new lifecycle tests) - focused: logger.test.ts 26/26, worker-pool.test.ts 22/22, grpc-extractor 39/39 Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(logger): harden runtime — pino-pretty packaging, sync writes, CLI UX Implements the 5 logger-runtime findings from the multi-agent code review and Codex's adversarial review (plan: docs/plans/2026-05-07-001-fix-pino-logger-runtime-hardening-plan.md). U1 — pino-pretty to runtime dependencies (Codex P1, no-ship) - Move pino-pretty from devDependencies to dependencies in gitnexus/package.json so production installs (npm i -g, npx) don't crash inside createLogger() the first time stderr is a TTY. - Lockfile regenerated; npm ls --omit=dev confirms placement. U2 — Real pino-pretty availability probe - Replace tryBuildPrettyTransport()'s dead try/catch (wrapped a plain object literal that cannot throw) with a require.resolve('pino-pretty') probe via createRequire. Memoize via _prettyAvailable cache. - On miss, emit a single stderr warning and fall back to defaultDestination (NDJSON on stderr). Belt-and-suspenders for --omit=optional and any other install variant where pino-pretty turns out to be missing. - Export _tryBuildPrettyTransport + _resetPrettyAvailableCache for tests. - Add 3 unit tests covering happy path, memoization, and warning bound. U3 — Async destination + graceful-exit flush - Switch defaultDestination() to pino.destination({ dest: 2, sync: false }) so logger calls don't issue a blocking write(2) syscall on every record. - Cache the destination in module-level _dest. Register process.on( 'beforeExit', flushSync) once at module load (gated on !VITEST so vitest's between-test cleanup doesn't fight _captureLogger). - Export flushLoggerSync() helper. Wire into existing shutdown handlers in cli/analyze.ts (SIGINT) and mcp/server.ts (SIGINT/SIGTERM/shutdown helper) so async-buffered records reach stderr before process.exit. - Add smoke test for flushLoggerSync's no-op-on-empty-state contract. U4 — Crash flush in serve.ts and api.ts - Add flushLoggerSync() between logger.error and process.exit(1) in serve.ts uncaughtException/unhandledRejection handlers and api.ts uncaughtException handler. - Pino v10 removed pino.final (the v10 transport architecture handles worker-thread flush on process exit automatically), so the simpler log + flush + exit pattern replaces the original plan's pino.final integration. Captured in the commented logger.ts JSDoc. - api.ts shutdown() also flushes before process.exit(0). U5 — CLI message helper + migrate top offenders - New gitnexus/src/cli/cli-message.ts exporting cliInfo/cliWarn/cliError. Each writes plain text to process.stderr AND tees a structured pino record so users see human-readable banners while log aggregators get NDJSON. Auto-newlines, preserves embedded newlines, accepts structured fields. - Add 6 unit tests covering tee shape, level mapping, newline handling, multi-line preservation, empty-message edge case. - Migrate top user-facing offenders identified in review: - cli/analyze.ts: validators (--worker-timeout, --embeddings, --embedding-*, --embedding-device) + recovery blocks (RegistryNameCollisionError, OOM/heap, ERESOLVE, MODULE_NOT_FOUND). Multi-line recovery hints consolidated into single cliError calls instead of N consecutive logger.error('') lines that emitted N empty NDJSON records. - cli/serve.ts: EADDRINUSE banner + Failed-to-start error. - cli/eval-server.ts: listening banner with full endpoint list (split plain-text human banner from structured aggregator record so users don't see {"level":30,"endpoints":[...]} in their terminal). - Update analyze-embeddings-limit.test.ts to spy on process.stderr.write instead of console.error (the validator now bypasses console). Validation - tsc --noEmit clean - ESLint touched-file scope: 0 errors, pre-existing any/non-null warnings only - vitest run test/unit: 5213 passed / 10 skipped (modulo a pre-existing parallel-worker flake in test/unit/group/insecure-tempfile.test.ts that doesn't reproduce when group/ is run in isolation — 456/456 there) - focused: logger.test.ts 19/19, cli-message.test.ts 6/6, analyze-embeddings-limit.test.ts 9/9 Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(cli): route hard-exit diagnostics through cliError to defeat buffer drain race Codex's adversarial review on PR #1336 flagged that nine `logger.error/warn` + `process.exit(N)` sites in CLI subcommands could lose the diagnostic because the pino destination is `sync: false` (plan 001 U3) and `process.exit` skips the `beforeExit` flush hook. Symptom: a non-zero exit with no visible message. U1: migrate the nine sites to `cliError`/`cliWarn` - gitnexus/src/cli/tool.ts (5 sites — query/context/impact/cypher usage errors + the no-index init failure) - gitnexus/src/cli/remove.ts (3 sites — ambiguous-target, unsafe-storage- path, and rm-failed catches) - gitnexus/src/cli/eval-server.ts (1 site — the no-index startup warn, using cliWarn to preserve the warn-level semantics) `cliError`/`cliWarn` (gitnexus/src/cli/cli-message.ts, plan 001 U5) write plain text directly to process.stderr AND tee a structured pino record. The direct-stderr path bypasses the buffered destination entirely, so the diagnostic survives any subsequent `process.exit` regardless of buffer state. Removed the now-unused `import { logger }` from tool.ts (lint caught it). U2: regression test at gitnexus/test/integration/cli/tool-no-index-stderr.test.ts - Spawns `node dist/cli/index.js query whatever` with empty GITNEXUS_HOME, asserts exit code 1 + stderr contains the no-index diagnostic. Pattern mirrors test/integration/mcp/server-startup.test.ts. Honesty caveat: the regression signal is not deterministic. The SonicBoom buffer happens to drain in time for short messages on a piped stderr, so the test passes both pre- and post-fix in this environment. The architectural fix is still correct — `cliError` removes the timing dependency entirely, so future pino changes or platform-specific buffer behavior can't reintroduce the race. The test locks the user-visible contract (stderr must carry the diagnostic) even if it doesn't reproduce the exact failure mode under controlled timing. Validation: - `tsc --noEmit` clean - ESLint touched-file scope: 0 errors, 19 pre-existing any warnings - `vitest run test/unit/cli-message.test.ts test/unit/logger.test.ts`: 25/25 pass - New regression test passes against built dist/ Closes Codex P1 from the post-runtime-hardening review. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(ci): replace console.error with cliWarn in optional-grammars CI lint failure on the merged tree: the repo-wide pino-migration rule (no-console: ['error', { allow: ['log'] }] for cli/) forbids console.error in CLI code. optional-grammars.ts was added by PR #1383 and used console.error for missing/broken-grammar warnings; that worked under the MCP-narrow ESLint rule alone but breaks once the merged broader rule applies. Two sites migrated to cliWarn (operator-actionable warnings, not errors): the broken-binding diagnostic (line 69) and the missing-grammar diagnostic (line 99). Each now writes plain text to stderr AND tees a structured logger.warn record with grammar/extensions/error fields. Also: hoisted opts?.relevantExtensions into a local const so the closure inside .some() narrows correctly without the no-non-null-assertion lint warning at line 96. Validation - ESLint optional-grammars.ts: 0 errors, 0 warnings (was 2 errors + 1 warning) - tsc --noEmit clean - vitest run cli-message + logger: 25/25 pass Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com>	2026-05-07 20:56:25 +01:00
Gergő Magyar	de63418f7e	fix(mcp): close MCP server timeout — stdout discipline + cold-start friction (#1383) ... * fix(lbug): route diagnostic logs to stderr to avoid MCP stdio corruption Replace console.log/console.warn with console.error in core/lbug so diagnostic messages reach stderr and never corrupt the JSON-RPC stream on MCP stdio. Per spec, the server MUST NOT write anything to stdout that is not a valid MCP message. - lbug-adapter.ts:367 - schema creation warning (MCP-reachable via lazy DB init from tool handlers) - lbug-adapter.ts:1047,1054 - legacy embedding fallback diagnostics (currently HTTP-only, but covered by upcoming no-console lint rule) - extension-loader.ts:191 - default warn handler fallback used during DuckDB extension loading * feat(mcp): add stdout sentinel via AsyncLocalStorage transport-write tagging Untagged process.stdout.write calls now redirect to stderr with a [mcp:stdout-redirect] prefix instead of corrupting the JSON-RPC frame stream. Identification is correctness-by-construction: the transport wraps every send() in withMcpWrite() (AsyncLocalStorage) and the sentinel checks isMcpWrite() per call. A byte-shape heuristic would have falsely rejected Content-Length frames (start with C, end with }) and misclassified multi-chunk writes. - gitnexus/src/mcp/stdio-context.ts: AsyncLocalStorage helpers + factory - gitnexus/src/mcp/server.ts: install sentinel in safeStdout Proxy, flush summary at process exit - gitnexus/src/mcp/compatible-stdio-transport.ts: wrap send() write in withMcpWrite so transport frames pass through cleanly - gitnexus/test/unit/mcp-stdout-sentinel.test.ts: 17 cases covering pass-through, redirect, prefix, truncation (default 200 / custom), rate limit (default 10), one-shot warning, summary, mixed sequences * feat(eslint): forbid console.log/warn and process.stdout.write in MCP-reachable code Add a narrow ESLint override for gitnexus/src/mcp/**, gitnexus/src/core/lbug/**, gitnexus/src/core/embeddings/**, and gitnexus/src/cli/mcp.ts that: - sets no-console: ['error', { allow: ['error'] }] — only console.error survives, since stderr is the only spec-safe channel for diagnostics while the MCP stdio transport owns stdout for JSON-RPC frames - adds no-restricted-syntax matching MemberExpression and CallExpression forms of process.stdout.write to close the bypass path that the AsyncLocalStorage sentinel cannot guarantee Migrates 18 pre-existing console.log/warn call sites in core/embeddings/ (embedder.ts, embedding-pipeline.ts) to console.error; these are reached from gitnexus_query semantic search and would have polluted MCP stdio once a query triggered the embedding pipeline. Adds eslint-disable-next-line comments in pool-adapter.ts at the four legitimate process.stdout.write sites — they ARE the captured-real-write infrastructure used by the sentinel and the silenceStdout/restoreStdout mechanism. The override is forward-compatible with feat/pino-logger (PR #1336) which adds a broader no-console rule for gitnexus/src/; the narrow rule here is a strict subset and rebases trivially when #1336 lands. * feat(setup): pin setup-generated MCP config to installed version, keep static configs on @latest The user-facing MCP config that 'gitnexus setup' writes into editor configs now references gitnexus@<installed-version> instead of gitnexus@latest, read dynamically from gitnexus/package.json#version at module load. This skips the npm-registry metadata roundtrip on every MCP connect and stays reproducible until the user explicitly upgrades. Static example configs and quickstart docs intentionally keep @latest: - .mcp.json, gitnexus-claude-plugin/.mcp.json - gitnexus-claude-plugin/skills/*/mcp.json (6 files) - README.md / gitnexus/README.md MCP examples Pinning these would create per-release version-bump churn for marginal (~100-500ms) savings. The dominant cold-cache cost is the native rebuild addressed separately by the GITNEXUS_SKIP_OPTIONAL_GRAMMARS env var. README adds a one-line steer above the @latest quickstart pointing repeated users at 'gitnexus setup' for the absolute-path config that bypasses npx entirely. Tests refactored to assert against the dynamic version (createRequire of package.json) so they don't break on every release bump: - gitnexus/test/unit/setup.test.ts - gitnexus/test/unit/setup-jsonc.test.ts - gitnexus/test/unit/setup-codex.test.ts - gitnexus/test/integration/setup-skills.test.ts (regex match) * feat(install,mcp): GITNEXUS_SKIP_OPTIONAL_GRAMMARS opt-out + missing-grammar warnings Postinstall scripts (build-tree-sitter-dart.cjs, build-tree-sitter-proto.cjs) gain a strict 'process.env.GITNEXUS_SKIP_OPTIONAL_GRAMMARS === "1"' early-exit so users without a C++ toolchain (or anyone wanting fast 'npm install gitnexus') can skip the native rebuild. Strict '=1' only — 'true', 'yes', '0' and any other value fall through to the rebuild. Add gitnexus/src/cli/optional-grammars.ts: cheap require.resolve probe for each optional grammar, with a stderr warning helper. The warning surfaces: - At MCP server start (cli/mcp.ts) — unconditional, since the server serves any indexed repo and we cannot pre-filter by language. - At 'gitnexus analyze' start (cli/analyze.ts) — conditional on the target repo containing .dart/.proto files (cheap glob), so users with no relevant code don't see noise. README documents the env var with the strict '=1' value and the trade-off (faster install, no Dart/Proto parsing until reinstalled). * test(mcp): child-process integration test asserts end-to-end stdout discipline Spawns 'node dist/cli/index.js mcp' as a child, drives the MCP stdio handshake (initialize -> initialized -> tools/list), reassembles every stdout chunk into Content-Length-framed JSON-RPC messages, and asserts zero stray bytes. Any byte outside a valid header-then-body window is captured and surfaced in the failure message alongside the server's stderr — this is the regression gate for U1 (no console.log/warn in MCP-reachable code) and U3 (AsyncLocalStorage stdout sentinel). Time budget: 5s local / 15s CI for first frame; 10s/30s total. Asserts the published GitNexus tool surface (list_repos, query, context, impact, detect_changes, rename) is reported by tools/list. Adds 'pretest:integration': 'node scripts/build.js' so 'npm run test:integration' rebuilds dist before the spawn — closes the 'stale dist masks regression' DX gap. * fix(mcp): address PR #1383 review — sentinel scope, grammar detection, lint, contract Blockers: - B2: detectMissingOptionalGrammars now actually require()s each grammar instead of require.resolve(). For 'file:' optional dependencies the package directory is always installed regardless of postinstall outcome, so resolve() never threw and the missing-grammar warning never fired for the exact target users (those who set GITNEXUS_SKIP_OPTIONAL_GRAMMARS=1 or whose native rebuild soft-failed). require() loads the entry, which triggers node-gyp-build and throws if .node is absent. Result memoized. Should-fix: - S1: Removed duplicate uncaughtException/unhandledRejection handlers from cli/mcp.ts. server.ts:startMCPServer already registers handlers with full stack traces; cli/mcp.ts handlers fired first with worse output and never got a chance to exit because server.ts shuts down immediately. - S2: Sentinel is now actually global. New setActiveStdoutWrite() in pool-adapter so silenceStdout/restoreStdout cycles preserve a registered wrapper instead of unwinding to raw realStdoutWrite. At startMCPServer: install sentinel.write as process.stdout.write AND register it as the active handler. Direct process.stdout.write calls from anywhere (console.log, dependency banners, etc.) now route through the sentinel instead of bypassing it. The transport's _safeStdout Proxy remains as belt-and-suspenders. - S3: ESLint no-restricted-syntax now also forbids destructuring of process.stdout (covers both 'const { write } = process.stdout' shapes and rest patterns). Minor: - M1: chunkToBuffer now handles plain Uint8Array (Buffer.from(u8)) instead of falling through to String(chunk) which produced '1,2,3,...' garbage. - M2: Untagged-write callbacks are now invoked on next tick per the Node Writable.write contract — both within and beyond the rate-limit cap. extractCallback handles the (chunk, cb) and (chunk, encoding, cb) overloads. - M3: setup.ts throws early if package.json#version is missing/non-string instead of emitting 'gitnexus@undefined'. - M4: parser-loader.ts console.warn → console.error; ESLint scope extended to gitnexus/src/core/tree-sitter/** so future violations are caught. New tests cover: - Plain Uint8Array redirect (asserts no String(chunk) garbage). - Writable callback fired async (next-tick) for both normal and past-rate-limit redirects. Validation: cd gitnexus && npx tsc --noEmit clean; vitest run 7863 passed, 11 skipped; eslint clean on MCP-reachable scope; integration test green against rebuilt dist/. * fix(mcp): close pre-sentinel stdout window + tighten contracts Address ce-code-review findings on PR #1383: P1 — Sentinel install order (was: stdout corruption window during mcpCommand pre-startup): - Add idempotent installGlobalStdoutSentinel() to mcp/stdio-context.ts. It captures realStdoutWrite/realStderrWrite, replaces process.stdout.write, and registers with pool-adapter's setActiveStdoutWrite — exactly once. - cli/mcp.ts now installs the sentinel as the FIRST line of mcpCommand, before warnMissingOptionalGrammars (which after the B2 fix actually require()s each native grammar binding and could emit node-gyp-build banners to raw stdout in the pre-sentinel window). - mcp/server.ts startMCPServer keeps a safety-net call to the same helper; the second invocation is a no-op. P1 — WriteFn type erasure: - WriteFn now declared as instead of , so the assignment and the setActiveStdoutWrite(sentinel.write) call don't silently cross a type boundary. P1 — extractCallback fragility: - Replaced backward-scan-with-undefined-break heuristic with a strict 'last arg if function' check matching the documented Writable.write contract. No longer breaks on a future (chunk, options, cb) overload. P2 — _detectionCache premature memoization: - Removed the explicit cache. Node's module cache already memoizes require() — calling detectMissingOptionalGrammars multiple times is cheap. Removing the module-level mutable state makes the helper trivially testable (no need for a reset hatch). P2 — Misleading 'reinstall' message on broken (not missing) grammars: - detectMissingOptionalGrammars now distinguishes MODULE_NOT_FOUND / node-gyp-build 'no native build' patterns from other errors (SyntaxError, EACCES, native crash). Broken bindings get an actionable stderr line naming the real failure instead of the misleading 'reinstall to enable' hint. Other: - mcp/core/lbug-adapter.ts updated with a KEEP-THIS-FILE note. Tests use the path as a vi.mock seam (calltool-dispatch.test.ts and 7 others); new non-test code may import core/lbug/pool-adapter.js directly. The maintainability finding flagging the shim as self-contradictory was incorrect — the shim has a real test purpose. Validation: tsc clean, vitest 7863 passed (no regressions), eslint clean on MCP-reachable scope, integration test green against rebuilt dist/. * fix(mcp): close import-time stdout corruption window Codex's adversarial review on PR #1383 found that even though cli/mcp.ts is loaded lazily by Commander, ITS static imports (startMCPServer, LocalBackend, installGlobalStdoutSentinel, warnMissingOptionalGrammars) evaluate synchronously when the module loads — well before mcpCommand's function body runs. Three of those four imports transitively pulled in core/lbug/pool-adapter.ts, which imports @ladybugdb/core at module top level. The native binding's init can write to raw stdout in that pre-sentinel window and corrupt the JSON-RPC frame stream. Fix: shrink cli/mcp.ts's static-import closure to a single zero-dep chain (mcp/stdio-context.js -> mcp/stdio-capture.js, both leaf-clean), install the sentinel as the first executable statement of mcpCommand, then dynamically import the heavy backend modules in parallel via await Promise.all. Per the plan at docs/plans/2026-05-06-002-fix-import-time-stdout-window-plan.md: - U1: New leaf module gitnexus/src/mcp/stdio-capture.ts owns the stdout-capture singleton state (realStdoutWrite, realStderrWrite, activeStdoutWrite + setActiveStdoutWrite/getActiveStdoutWrite). Zero non-node: imports — adding any would re-introduce the hazard. - U2: pool-adapter.ts re-exports the relocated symbols under the existing names so the test mock seam (8+ files use vi.mock on mcp/core/lbug-adapter.ts which re-exports * from pool-adapter) keeps working without churn. restoreStdout and the watchdog now read the active handler via getActiveStdoutWrite(). stdio-context.ts imports from stdio-capture directly. - U3: cli/mcp.ts's static imports collapse to one (installGlobalStdoutSentinel). startMCPServer / LocalBackend / warnMissingOptionalGrammars become parallel await import() inside mcpCommand, after the sentinel install. - U4: New regression test gitnexus/test/integration/mcp/import-closure.test.ts spawns a child Node process that imports dist/cli/mcp.js (without invoking mcpCommand), inspects the CJS module cache via createRequire, and asserts @ladybugdb/core (and tree-sitter native bindings) are NOT in the static-import closure. Characterization-first: this test was authored to fail against the pre-fix code and confirmed to do so before U1-U3 landed. Validation: tsc clean; vitest 7865 passed / 11 skipped (2 new U4 cases); eslint clean on MCP-reachable scope; integration server-startup test green against rebuilt dist/. * fix(mcp): drop dead ESLint selector + suppress redundant grammar warning Two minor PR #1383 review findings: 1. eslint.config.mjs: removed Selector 3 (`Property[key.name='write'].properties:has(...)`). `.properties` is not a valid attribute on a Property node in the ESTree AST, so the :has clause never matched — dead code. Selector 4 covers the canonical `const { write } = process.stdout` shape; tightened its comment to make that explicit. 2. cli/mcp.ts: removed the unconditional warnMissingOptionalGrammars call at MCP startup. The analyze path already emits this warning at index time with relevantExtensions filtered to the repo's actual file types, and a repo can only be served by MCP after analyze has run. Repeating the warning unconditionally on every MCP session was pure noise on machines whose indexed repos don't use .dart/.proto. * chore(mcp): address PR #1383 review nits Three minor hygiene findings from the production-readiness review: - cli/mcp.ts: rewrite stale comment that described warnMissingOptionalGrammars as living inside mcpCommand. The call was removed in ca617552 — this path no longer invokes it at all. - test/integration/mcp/import-closure.test.ts: same comment drift fixed. Test assertion is unchanged and still passes for the right reason (cli/mcp.js's static-import closure is leaf-only). - mcp/server.ts: rename _safeStdout to safeStdout. The leading underscore conventionally signals "intentionally unused" but the Proxy is passed to CompatibleStdioServerTransport on the next line. No behavior change. Typecheck clean; ESLint MCP-reachable scope still 0 errors.

Gergő Magyar	6ec1f04604	chore(quality): exclude test/fixtures from CodeQL, ESLint, and Prettier (#1313) ... Test fixtures are intentionally synthetic inputs (broken/unused code, malformed samples) used to exercise the analyzer.
