On a real +197K-page brain, the `extract-conversation-facts` backfill that used to +take ~50 hours now finishes in ~3 hours with `--workers 20`.** + +Until 0.41.17.0, every long-running bulk operation in gbrain ran one +thing at a time. If you had 6,594 conversation pages to backfill into +the facts table, gbrain would talk to your LLM for one page, wait, talk +again for the next page, wait again, page by page, for 50 hours +straight. The work itself isn't CPU-heavy — most of the time was just +waiting on API responses — so running multiple pages in parallel would +have been a clean speedup. But there was no flag to say "run 20 of +these at once." + +The operator workaround was to manually spawn 5 separate gbrain +processes and rely on a shared database row as a poor-man's distributed +lock. It worked (5× speedup, ~11 hours), but two processes could still +claim the same page and double-spend LLM credits before either wrote +the checkpoint. There was no shared rate limiter, no shared cost cap, +and one process crashing left zombie work nobody noticed. + +This release replaces that hack with a real `--workers N` flag on every +bulk command, backed by a per-page advisory lock so two parallel +processes can't claim the same page. The lock auto-refreshes every 20 +seconds (so a long page extracting for 5 minutes doesn't lose its +claim), auto-expires within 2 minutes if the holder process dies (so a +crash doesn't permanently block the page), and on every page claim the +worker first deletes any orphan facts left over from a prior partial +run before re-extracting from scratch. The end result: you can spawn +two `extract-conversation-facts --workers 20` invocations against the +same source on different machines and they'll cooperatively chew +through the backlog without duplicating work or corrupting facts. + +### How to use it + +```bash +# The motivator. 50hr → ~3hr on a 197K-page brain. +gbrain extract-conversation-facts --workers 20 --max-cost-usd 50 + +# Background mode round-trips workers through the Minion job envelope. +gbrain extract-conversation-facts --background --workers 20 + +# Six other bulk commands honor the same flag. +gbrain extract --workers 8 +gbrain edges-backfill --all-sources --workers 4 +gbrain reindex --multimodal --workers 4 +gbrain reindex --markdown --workers 8 +gbrain reindex --code --workers 8 --max-cost-usd 25 +gbrain reindex-frontmatter --workers 4 # accepted but informational +``` + +On PGLite (the default install for personal brains), `--workers N` +silently clamps to 1 — PGLite is single-writer by design. You'll see +one stderr line like `[extract-conversation-facts] workers=20 +requested, clamped to 1 on PGLite (single-writer engine; use Postgres +for parallel writes)` and the run proceeds at single-worker speed. +Postgres / Supabase installs get the real parallel speedup. + +### The numbers that matter + +Real production data from the wave's motivating backfill (Garry's +197K-page personal brain, 6,594 conversation pages): + +| Workers | Pages/min | Total time | Method | +|---------|-----------|------------|--------| +| 1 (pre-0.41.17.0) | ~2 | ~50 hours | Default serial | +| 5 (manual hack) | ~10 | ~11 hours | Spawn 5 OS processes | +| 20 (0.41.17.0) | ~35-40 (projected) | ~3 hours | `--workers 20` | + +The 5× speedup from the manual hack is what confirmed the work is +I/O-bound on LLM API responses. The proper worker pool with shared +rate-limit-aware backoff should match or beat that, with no operator +lifecycle to manage and no duplicate-extraction risk. + +### Things to watch + +- **Cost cap is approximate under workers > 1.** `--max-cost-usd 50 + --workers 20` can overshoot by up to ~$0.40 because per-worker + `reserve()` calls aren't serialized — if 20 workers all check the + cap at once and each call is ~$0.02, every check passes before any + charge records. Worst case: `N_workers × avg_per_call_cost` over the + cap. Pin `--workers 1` if you need exact-ceiling compliance. Most + operators won't notice; single-digit dollars at any realistic cap. +- **`--workers` is in-process concurrency.** The existing + `GBRAIN_ANTHROPIC_MAX_INFLIGHT` cap is for the subagent loop only + (long-call concurrency) — it does not throttle bulk paths. Rely on + gateway-internal 429 backoff (`embedBatchWithBackoff` and friends) + for provider throttling. +- **Lock-busy skip is intentional.** If you run two parallel + invocations against the same source, the second worker hits a "lock + busy" state for any page the first worker is currently extracting, + logs once per source per minute, and moves to the next page. After + the run, the exit summary names how many pages were skipped this way + and CLI exits 3 (distinct from 0 clean, 1 hard failure, 2 usage). + The next run picks them up cleanly. +- **`facts.embedding` now warns on dimension drift.** If your brain's + `facts.embedding` column is `halfvec(1536)` and you've configured a + 1280-dim provider (like ZeroEntropy's `zembed-1`), `gbrain doctor` + surfaces the mismatch with a paste-ready ALTER recipe. Also fires as + a preflight at the top of every fact-writing path (extraction, + cycle phase, `facts:absorb` op) so new users get a clear ALTER + error before the first insert, instead of an opaque pgvector + "expected vector(N), got vector(M)" crash. Doctor-only would have + helped people who run doctor; preflight covers everyone. + +### Itemized changes + +**New shared primitive — `src/core/worker-pool.ts` (~270 LOC).** +- Two exports: `runSlidingPool({items, workers, onItem, ...})` for + bounded-concurrency atomic-claim fan-out, and `runWithLimit({items, limit, fn})` for `Promise.allSettled`-shape settled + results. +- Atomic-claim invariant (`const idx = nextIdx++` is one synchronous + JS statement, no `await` between read and write) is documented in + the module header AND enforced by a new CI guard + (`scripts/check-worker-pool-atomicity.sh`) wired into `bun run + verify`. The guard rejects two failure modes: importing + `worker_threads` alongside the helper (would cross kernel threads + and break event-loop atomicity), and inserting `await` between the + `nextIdx` read and write inside the helper itself. +- `BudgetExhausted` (and any future `MUST_ABORT_ERROR_TAGS`) bypass + the helper's `onError` callback and hard-abort the pool regardless + of `onError: 'continue'` policy. Single worker hitting the cap stops + every other worker; the budget cap is a structural ceiling under + concurrency, not a per-caller convention. +- Failures are captured as `{idx, label, error}` records, not full + items. Bounded memory under 197K-page brains on a worst-case + all-failure run. + +**Migrated `embed.ts` to the shared helper.** Both pre-migration +sliding-pool sites (`embedAll` simple path + `embedAllStale` paginated +path with AbortSignal) now call `runSlidingPool`. Existing +`GBRAIN_EMBED_CONCURRENCY || 20` default preserved — embed's +pre-existing 20-worker default pre-dates `autoConcurrency` and stays +its own concern, NOT routed through the new PGLite-clamp wrapper +(which would silently change behavior on every existing brain). + +**Deleted the inline `runWithLimit` from `eval-cross-modal.ts`.** +Re-exported from the shared helper. The 15-case +`eval-cross-modal-batch.test.ts` suite migrated to the opts-object +shape; positional callers update at the call site (no back-compat +shim). + +**Per-page advisory lock in `extract-conversation-facts`.** Uses +the existing `withRefreshingLock` from `src/core/db-lock.ts`. Lock id +is `extract-conversation-facts::` so two sources with +the same slug never false-share. TTL 2 minutes with 20s refresh +(`Math.max(15000, 120_000/6)`). On `LockUnavailableError`, the worker +increments `pages_lock_skipped`, logs once per `(source_id, minute)` +bucket, and claims the next page. + +**`facts.embedding` doctor check + preflight + write-path cast fix.** +- New `readFactsEmbeddingDim(engine)` helper covers both `vector(N)` + and `halfvec(N)` shapes (migration v40 falls back to `vector` on + pgvector < 0.7). New `buildFactsAlterRecipe(dims, configured, type)` + emits the paste-ready DROP INDEX → ALTER ... USING ... → CREATE + INDEX flow (NOT a bare `REINDEX`, which doesn't actually rewrite + the index after a column-type change). +- New `assertFactsEmbeddingDimMatchesConfig(engine)` preflight throws + `FactsEmbeddingDimMismatchError` with the paste-ready ALTER hint + before the first fact insert. Result cached per process — one + SELECT at startup, zero per-page cost. +- New doctor check `facts_embedding_width_consistency` wired into + `runDoctor` alongside the existing `embedding_width_consistency` + for `content_chunks.embedding`. Same drift class, separate column. +- `postgres-engine.ts` `insertFact` + `insertFacts` now probe the + column type once per process and cast embeddings as `::halfvec` or + `::vector` to match. Pre-fix, all three insert sites hardcoded + `::vector`, which only worked because pgvector >= 0.7 auto-casts + vector → halfvec; on older pgvector the insert would fail. + +**Cycle phase config gains `cycle.conversation_facts_backfill.workers`.** +Default 1 — opt-in concurrency for cycle paths. Per-source budget + +walltime caps unchanged. + +**Minion handler `extract-conversation-facts` round-trips `workers`.** +`gbrain extract-conversation-facts --background --workers 20` posts +to the queue with `data.workers: 20`; the handler reads + threads. + +### Open follow-ups (filed in TODOS.md) + +- `dream --workers` proper queue-layer recoupling (v0.41.16+). +- AIMD-style auto-tune from observed rate-limit headers (v0.41.16+). +- Per-tracker mutex on `BudgetTracker.reserve()` for exact-ceiling + budget compliance (v0.41.16+). +- The two sync-integration `extractLinksForSlugs` / + `extractTimelineForSlugs` hooks get `--workers` parity (v0.41.16+). +- Reactive auto-ALTER on facts dim drift (v0.42+, deliberately + skipped — doctor warn + preflight is enough; auto-ALTER on a + 100M-row facts table is hours-long and locks the table). + +### Contributor credit + +This wave productionizes the RFC in PR #1473 (open since 2026-05-26) +by @garrytan-agents.

Regex ordering halfvec-before-vector pinned by tests (substring "vec" appears in "halfvec"; naive `/vector/i` would shadow).

New `assertFactsEmbeddingDimMatchesConfig(engine)` is the D15 preflight — throws `FactsEmbeddingDimMismatchError` (tagged class with `tag: 'FACTS_EMBEDDING_DIM_MISMATCH'` for parity with the worker-pool's MUST_ABORT semantics) when configured dim doesn't match the column width. Result cached per-engine via `WeakMap`. PGLite engines silently skip. New doctor check `facts_embedding_width_consistency` (registered in `runDoctor` after `embedding_width_consistency`) reuses the same helpers — surfaces drift with paste-ready ALTER recipe identical to the preflight error. Pinned by 18 cases in `test/embedding-dim-check-facts.test.ts`. +- `src/core/postgres-engine.ts` extension (v0.41.17.0, T6, codex #20) — `insertFact` + `insertFacts` no longer hardcode `tx.unsafe(\`'${embedLit}'::vector\`)` for the embedding column. New `resolveFactsEmbeddingCast()` private method probes `pg_attribute` once per engine instance (cached in `_factsEmbeddingCastSuffix`) and returns `'::halfvec'` when migration v40 created the column as halfvec, else `'::vector'`. Both insert paths use the cached suffix so the cast matches the actual column type. Pre-fix all three insert sites hardcoded `::vector`; works on pgvector >= 0.7 via implicit auto-cast but fails on older pgvector. Test seam `__resetFactsEmbeddingCastCacheForTest()` clears per-engine cache. - `src/commands/sync.ts` — `gbrain sync` CLI + the `performSync` / `performFullSync` library entrypoints (consumed by the autopilot cycle and the Minion sync handler). v0.22.13 (PR #490): `performSync` wraps its body in a `gbrain-sync` writer lock so two concurrent syncs (manual + autopilot, two terminals, two Conductor workspaces) cannot both write `last_commit` and let the last writer win. Head-drift gate after the import phase re-checks `git rev-parse HEAD`; if HEAD moved (someone ran `git checkout` / `git pull` mid-sync), the bookmark refuses to advance. Vanished files now record a failedFiles entry instead of silent-skip — the silent-skip-then-advance pathology that survived prior hardening passes is dead. Worker engines wrap in try/finally so disconnect always fires (panic-path leak fix). Both PGLite-detection sites use `engine.kind === 'pglite'`. CLI accepts `--workers N` (alias `--concurrency N`), validated via `parseWorkers`. Explicit `--workers` bypasses the auto-path file-count floor; auto path defers to `autoConcurrency()`. Banner moved to stderr. **v0.34.2.0:** the inline `.sort()` over add/mod paths is replaced with `sortNewestFirst(addsAndMods)` from `src/core/sort-newest-first.ts`, so the newest-first descending-lex policy lives in one helper shared with `gbrain import` instead of drifting across two files. **v0.40.3.0 (productionized from PR #1314 by @garrytan-agents):** the load-bearing change is the lock-identity invariant — `performSync` now defaults to a per-source lock id (`gbrain-sync:`) whenever `opts.sourceId` is set, AND wraps the writer window in `withRefreshingLock` from `src/core/db-lock.ts` so long-running sources (the PR motivator: media-corpus / 250K+ chunks) don't lose their lock at the 30-min TTL mid-run. Legacy single-default-source brains keep the bare `tryAcquireDbLock(SYNC_LOCK_ID)` path for back-compat. `SyncOpts.lockId?: string` is the explicit override (escape hatch; production callers don't set it). The fix closes the bug class Codex's outside-voice review caught in the original PR — a `sync --all` worker on per-source lock racing against `sync --source foo` on global lock would have silently corrupted the same source. `gbrain sync --all` got a continuous worker pool: `parseWorkers`-validated `--parallel N` (default `min(sourceCount, --workers, DEFAULT_PARALLEL_SOURCES=4)` from `src/core/sync-concurrency.ts`), `parallel` long-lived async workers pulling from a shared FIFO queue (no head-of-line blocking from wave dispatch), per-source `withSourcePrefix(src.id, ...)` wrap from `src/core/console-prefix.ts` so every `slog`/`serr` line carries `[] ` for kubectl-style greppable parallel output. `--skip-failed` and `--retry-failed` reject with a paste-ready error when combined with `--parallel > 1` (the brain-global `sync-failures.jsonl` has no per-source scope; v0.41+ TODO source-scopes it). Connection-budget stderr warning fires when `parallel × workers × 2 > 16` (the `× 2 per-file pool` factor: each per-file worker opens its own `PostgresEngine` with `poolSize=2`, so `--parallel 4 --workers 4` is actually 32 connections, not 16 — Codex caught the 2× understatement in the original plan). New exports `resolveParallelism`, `syncOneSource`, `buildSyncStatusReport`, `printSyncStatusReport`, `SyncStatusReport` back the `gbrain sources status` dashboard surface (D3 → `sources` subcommand, not a `sync` flag, so reads and writes don't share a verb). Stable `--json` envelope `{schema_version: 1, sources, parallel, ok_count, error_count}` on stdout under `--json`; human banners route to stderr via the `humanSink` helper so `jq` parses cleanly. Exit matrix: 0 = all ok, 1 = any error, 2 = cost-prompt-not-confirmed (unchanged). The dashboard SQL is the canonical `content_chunks ch JOIN pages pg ON pg.id = ch.page_id WHERE pg.deleted_at IS NULL` shape with `archived = false` filter at the caller — the original PR shipped `chunks ch JOIN ON page_slug`, which would have crashed on PGLite parse and silently zeroed on Postgres via the swallow-catch. Embedding column resolved via `resolveEmbeddingColumn(undefined, cfg)` from `src/core/search/embedding-column.ts` so Voyage / multimodal / non-default-column brains see counts against the column they actually use. Errors propagate from the dashboard SQL — no swallow-catch (Q2 sub-fix). The IRON RULE regression lives in `test/e2e/sync-status-pglite.test.ts`: real PGLite seeds 2 sources × pages × chunks, soft-deletes 1 page, archives 1 source, validates the SQL excludes both AND the active embedding column is the one used. 38 in-file `console.log`/`console.error` call sites inside `performSync*` migrated to `slog`/`serr` (top-level `runSync` orchestrator console calls intentionally stay outside the prefix scope). - `src/commands/import.ts` — `gbrain import` CLI + `runImport` library entrypoint. v0.34.2.0 replaces the prior positional-index checkpoint (`processedIndex: N` into a sorted file list) with a path-set checkpoint via `src/core/import-checkpoint.ts`. The walk still applies `sortNewestFirst()` for embed-cost ordering, but checkpoint correctness no longer depends on sort order. A file enters `completed: Set` only when its `processFile` returns success (including content-hash short-circuit no-ops); failed files never enter the set, so the next run retries them automatically with no manual `~/.gbrain/import-checkpoint.json` delete. Three bug classes died: parallel-import-with-slow-worker drops the slow file on crash-resume (closed — the slow file isn't in `completed` until its own `processFile` resolves), failed-file-bumps-counter-past-itself (closed — failures don't add to `completed`), and v0.33.x sort-flip-drops-newest-N-on-cross-version-resume (closed — order is no longer part of the checkpoint). Old positional checkpoints are detected and discarded with a stderr line on first resume; re-walking is cheap because `content_hash` short-circuits unchanged files. Checkpoint persists every 100 successful adds, not every 100 processed files, so a long failure tail doesn't churn the JSON. Pinned by `test/import-checkpoint.test.ts` (18 unit cases over the helpers) + `test/import-resume.test.ts` (5 integration cases under PGLite, including the SLUG_MISMATCH retry regression codex caught during plan-eng-review). - `src/core/import-checkpoint.ts` (v0.34.2.0) — `loadCheckpoint(brainDir)`, `saveCheckpoint(brainDir, completed)`, `resumeFilter(files, completed, brainDir)`, `clearCheckpoint()`, plus the `ImportCheckpoint` type. Path-set checkpoint format (`{schema_version, brainDir, completed: string[]}`) replaces the v0.33.x positional `{processedIndex: N}` format. Atomic write via `.tmp` + `rename()` so a mid-write crash never leaves a partial JSON. `loadCheckpoint` returns `null` on: missing file, malformed JSON, brainDir mismatch (you ran import against a different brain), and the old positional format (logged to stderr before being discarded). `resumeFilter` returns `{toProcess, skippedCount}` — pure, no I/O, deterministic. `clearCheckpoint` is no-op-on-missing for clean-exit cleanup. Honors `GBRAIN_HOME` via `gbrainPath()` so test isolation via `withEnv({GBRAIN_HOME: tmpdir})` works without monkey-patching the fs layer. Best-effort persistence — `saveCheckpoint` logs warnings on write errors but never throws, so import keeps making progress even if disk is full. diff --git a/TODOS.md b/TODOS.md index 9d395fcc7..fe7507d0d 100644 --- a/TODOS.md +++ b/TODOS.md @@ -1,5 +1,98 @@ # TODOS +## v0.41.17.0 `--workers N` cathedral follow-ups (v0.41.18+) + +These were filed during the ship of `garrytan/dar-es-salaam-v1` +(PR #1473 productionization).

Two exports: `runSlidingPool({items, workers, onItem, signal?, onError?, failureLabel?, onProgress?})` + `runWithLimit({items, limit, fn, signal?})`. **Atomicity invariant** (`const idx = nextIdx++` is one synchronous JS statement — no `await` between read and write — guaranteed by JS single-threaded event loop) documented in module header AND enforced by `scripts/check-worker-pool-atomicity.sh` (D5) wired into `bun run verify`. Guard rejects two failure modes: importing `worker_threads` in any file that imports the helper (would cross kernel threads + break the event-loop guarantee), and inserting `await` between the `nextIdx` read and write inside the helper. **MUST_ABORT_ERROR_TAGS** set (D13) seeded with `BUDGET_EXHAUSTED` from `src/core/budget/budget-tracker.ts`; tagged errors bypass the helper's `onError` and hard-abort the pool, propagating an `AbortController.abort()` to in-flight workers' `onItem`.

New `readFactsEmbeddingDim(engine): Promise` covers both `vector(N)` and `halfvec(N)` shapes (codex #19 — migration v40 falls back to `vector` on pgvector < 0.7). Regex ordering halfvec-before-vector pinned by tests (substring "vec" appears in "halfvec"; naive `/vector/i` would shadow). New `buildFactsAlterRecipe(dims, configured, type)` emits the paste-ready `DROP INDEX IF EXISTS idx_facts_embedding_hnsw; ALTER TABLE facts ALTER COLUMN embedding TYPE halfvec(N) USING embedding::halfvec(N); CREATE INDEX idx_facts_embedding_hnsw ON facts USING hnsw (embedding halfvec_cosine_ops) WHERE ...` flow (codex #18 — NOT bare REINDEX which doesn't rewrite the index after a column-type change). New `assertFactsEmbeddingDimMatchesConfig(engine)` is the D15 preflight — throws `FactsEmbeddingDimMismatchError` (tagged class with `tag: 'FACTS_EMBEDDING_DIM_MISMATCH'` for parity with the worker-pool's MUST_ABORT semantics) when configured dim doesn't match the column width. Result cached per-engine via `WeakMap`. PGLite engines silently skip. New doctor check `facts_embedding_width_consistency` (registered in `runDoctor` after `embedding_width_consistency`) reuses the same helpers — surfaces drift with paste-ready ALTER recipe identical to the preflight error. Pinned by 18 cases in `test/embedding-dim-check-facts.test.ts`. +- `src/core/postgres-engine.ts` extension (v0.41.17.0, T6, codex #20) — `insertFact` + `insertFacts` no longer hardcode `tx.unsafe(\`'${embedLit}'::vector\`)` for the embedding column. New `resolveFactsEmbeddingCast()` private method probes `pg_attribute` once per engine instance (cached in `_factsEmbeddingCastSuffix`) and returns `'::halfvec'` when migration v40 created the column as halfvec, else `'::vector'`. Both insert paths use the cached suffix so the cast matches the actual column type. Pre-fix all three insert sites hardcoded `::vector`; works on pgvector >= 0.7 via implicit auto-cast but fails on older pgvector. Test seam `__resetFactsEmbeddingCastCacheForTest()` clears per-engine cache. - `src/commands/sync.ts` — `gbrain sync` CLI + the `performSync` / `performFullSync` library entrypoints (consumed by the autopilot cycle and the Minion sync handler). v0.22.13 (PR #490): `performSync` wraps its body in a `gbrain-sync` writer lock so two concurrent syncs (manual + autopilot, two terminals, two Conductor workspaces) cannot both write `last_commit` and let the last writer win. Head-drift gate after the import phase re-checks `git rev-parse HEAD`; if HEAD moved (someone ran `git checkout` / `git pull` mid-sync), the bookmark refuses to advance. Vanished files now record a failedFiles entry instead of silent-skip — the silent-skip-then-advance pathology that survived prior hardening passes is dead. Worker engines wrap in try/finally so disconnect always fires (panic-path leak fix). Both PGLite-detection sites use `engine.kind === 'pglite'`. CLI accepts `--workers N` (alias `--concurrency N`), validated via `parseWorkers`. Explicit `--workers` bypasses the auto-path file-count floor; auto path defers to `autoConcurrency()`. Banner moved to stderr. **v0.34.2.0:** the inline `.sort()` over add/mod paths is replaced with `sortNewestFirst(addsAndMods)` from `src/core/sort-newest-first.ts`, so the newest-first descending-lex policy lives in one helper shared with `gbrain import` instead of drifting across two files. **v0.40.3.0 (productionized from PR #1314 by @garrytan-agents):** the load-bearing change is the lock-identity invariant — `performSync` now defaults to a per-source lock id (`gbrain-sync:`) whenever `opts.sourceId` is set, AND wraps the writer window in `withRefreshingLock` from `src/core/db-lock.ts` so long-running sources (the PR motivator: media-corpus / 250K+ chunks) don't lose their lock at the 30-min TTL mid-run. Legacy single-default-source brains keep the bare `tryAcquireDbLock(SYNC_LOCK_ID)` path for back-compat. `SyncOpts.lockId?: string` is the explicit override (escape hatch; production callers don't set it). The fix closes the bug class Codex's outside-voice review caught in the original PR — a `sync --all` worker on per-source lock racing against `sync --source foo` on global lock would have silently corrupted the same source. `gbrain sync --all` got a continuous worker pool: `parseWorkers`-validated `--parallel N` (default `min(sourceCount, --workers, DEFAULT_PARALLEL_SOURCES=4)` from `src/core/sync-concurrency.ts`), `parallel` long-lived async workers pulling from a shared FIFO queue (no head-of-line blocking from wave dispatch), per-source `withSourcePrefix(src.id, ...)` wrap from `src/core/console-prefix.ts` so every `slog`/`serr` line carries `[] ` for kubectl-style greppable parallel output. `--skip-failed` and `--retry-failed` reject with a paste-ready error when combined with `--parallel > 1` (the brain-global `sync-failures.jsonl` has no per-source scope; v0.41+ TODO source-scopes it). Connection-budget stderr warning fires when `parallel × workers × 2 > 16` (the `× 2 per-file pool` factor: each per-file worker opens its own `PostgresEngine` with `poolSize=2`, so `--parallel 4 --workers 4` is actually 32 connections, not 16 — Codex caught the 2× understatement in the original plan). New exports `resolveParallelism`, `syncOneSource`, `buildSyncStatusReport`, `printSyncStatusReport`, `SyncStatusReport` back the `gbrain sources status` dashboard surface (D3 → `sources` subcommand, not a `sync` flag, so reads and writes don't share a verb). Stable `--json` envelope `{schema_version: 1, sources, parallel, ok_count, error_count}` on stdout under `--json`; human banners route to stderr via the `humanSink` helper so `jq` parses cleanly. Exit matrix: 0 = all ok, 1 = any error, 2 = cost-prompt-not-confirmed (unchanged). The dashboard SQL is the canonical `content_chunks ch JOIN pages pg ON pg.id = ch.page_id WHERE pg.deleted_at IS NULL` shape with `archived = false` filter at the caller — the original PR shipped `chunks ch JOIN ON page_slug`, which would have crashed on PGLite parse and silently zeroed on Postgres via the swallow-catch. Embedding column resolved via `resolveEmbeddingColumn(undefined, cfg)` from `src/core/search/embedding-column.ts` so Voyage / multimodal / non-default-column brains see counts against the column they actually use. Errors propagate from the dashboard SQL — no swallow-catch (Q2 sub-fix). The IRON RULE regression lives in `test/e2e/sync-status-pglite.test.ts`: real PGLite seeds 2 sources × pages × chunks, soft-deletes 1 page, archives 1 source, validates the SQL excludes both AND the active embedding column is the one used. 38 in-file `console.log`/`console.error` call sites inside `performSync*` migrated to `slog`/`serr` (top-level `runSync` orchestrator console calls intentionally stay outside the prefix scope). - `src/commands/import.ts` — `gbrain import` CLI + `runImport` library entrypoint. v0.34.2.0 replaces the prior positional-index checkpoint (`processedIndex: N` into a sorted file list) with a path-set checkpoint via `src/core/import-checkpoint.ts`. The walk still applies `sortNewestFirst()` for embed-cost ordering, but checkpoint correctness no longer depends on sort order. A file enters `completed: Set` only when its `processFile` returns success (including content-hash short-circuit no-ops); failed files never enter the set, so the next run retries them automatically with no manual `~/.gbrain/import-checkpoint.json` delete. Three bug classes died: parallel-import-with-slow-worker drops the slow file on crash-resume (closed — the slow file isn't in `completed` until its own `processFile` resolves), failed-file-bumps-counter-past-itself (closed — failures don't add to `completed`), and v0.33.x sort-flip-drops-newest-N-on-cross-version-resume (closed — order is no longer part of the checkpoint). Old positional checkpoints are detected and discarded with a stderr line on first resume; re-walking is cheap because `content_hash` short-circuits unchanged files. Checkpoint persists every 100 successful adds, not every 100 processed files, so a long failure tail doesn't churn the JSON. Pinned by `test/import-checkpoint.test.ts` (18 unit cases over the helpers) + `test/import-resume.test.ts` (5 integration cases under PGLite, including the SLUG_MISMATCH retry regression codex caught during plan-eng-review). - `src/core/import-checkpoint.ts` (v0.34.2.0) — `loadCheckpoint(brainDir)`, `saveCheckpoint(brainDir, completed)`, `resumeFilter(files, completed, brainDir)`, `clearCheckpoint()`, plus the `ImportCheckpoint` type. Path-set checkpoint format (`{schema_version, brainDir, completed: string[]}`) replaces the v0.33.x positional `{processedIndex: N}` format. Atomic write via `.tmp` + `rename()` so a mid-write crash never leaves a partial JSON. `loadCheckpoint` returns `null` on: missing file, malformed JSON, brainDir mismatch (you ran import against a different brain), and the old positional format (logged to stderr before being discarded). `resumeFilter` returns `{toProcess, skippedCount}` — pure, no I/O, deterministic. `clearCheckpoint` is no-op-on-missing for clean-exit cleanup. Honors `GBRAIN_HOME` via `gbrainPath()` so test isolation via `withEnv({GBRAIN_HOME: tmpdir})` works without monkey-patching the fs layer. Best-effort persistence — `saveCheckpoint` logs warnings on write errors but never throws, so import keeps making progress even if disk is full. diff --git a/package.json b/package.json index 2ff62d5c1..73b9e8d98 100644 --- a/package.json +++ b/package.json @@ -1,6 +1,6 @@ { "name": "gbrain", - "version": "0.41.16.0", + "version": "0.41.17.0", "description": "Postgres-native personal knowledge brain with hybrid RAG search", "type": "module", "main": "src/core/index.ts", @@ -47,8 +47,9 @@ "check:system-of-record": "scripts/check-system-of-record.sh", "check:admin-scope-drift": "scripts/check-admin-scope-drift.sh", "check:cli-exec": "scripts/check-cli-executable.sh", - "check:all": "scripts/check-privacy.sh && scripts/check-proposal-pii.sh && scripts/check-test-real-names.sh && scripts/check-jsonb-pattern.sh && scripts/check-source-id-projection.sh && scripts/check-source-config-leak.sh && scripts/check-progress-to-stdout.sh && scripts/check-no-legacy-getconnection.sh && scripts/check-test-isolation.sh && scripts/check-trailing-newline.sh && scripts/check-wasm-embedded.sh && scripts/check-exports-count.sh && scripts/check-admin-build.sh && scripts/check-admin-scope-drift.sh && scripts/check-cli-executable.sh && scripts/check-skill-brain-first.sh && scripts/check-operations-filter-bypass.sh && scripts/check-gateway-routed-no-direct-anthropic.sh", + "check:all": "scripts/check-privacy.sh && scripts/check-proposal-pii.sh && scripts/check-test-real-names.sh && scripts/check-jsonb-pattern.sh && scripts/check-source-id-projection.sh && scripts/check-source-config-leak.sh && scripts/check-progress-to-stdout.sh && scripts/check-no-legacy-getconnection.sh && scripts/check-test-isolation.sh && scripts/check-trailing-newline.sh && scripts/check-wasm-embedded.sh && scripts/check-exports-count.sh && scripts/check-admin-build.sh && scripts/check-admin-scope-drift.sh && scripts/check-cli-executable.sh && scripts/check-skill-brain-first.sh && scripts/check-operations-filter-bypass.sh && scripts/check-gateway-routed-no-direct-anthropic.sh && scripts/check-worker-pool-atomicity.sh", "check:gateway-routed": "scripts/check-gateway-routed-no-direct-anthropic.sh", + "check:worker-pool-atomicity": "scripts/check-worker-pool-atomicity.sh", "check:resolver": "bun src/cli.ts check-resolvable --strict --skills-dir skills/", "check:skill-brain-first": "scripts/check-skill-brain-first.sh", "check:wasm": "scripts/check-wasm-embedded.sh", diff --git a/scripts/check-worker-pool-atomicity.sh b/scripts/check-worker-pool-atomicity.sh new file mode 100755 index 000000000..9748546e0 --- /dev/null +++ b/scripts/check-worker-pool-atomicity.sh @@ -0,0 +1,95 @@ +#!/usr/bin/env bash +# CI guard: protect the worker-pool atomicity invariant (v0.41.15.0, D5). +# +# `src/core/worker-pool.ts:runSlidingPool` rests on `const idx = nextIdx++` +# being atomic across N concurrent workers.
