From acf48b940a984c83310e33eab8c25a98e6dca1e0 Mon Sep 17 00:00:00 2001 From: Dmitry Teryaev Date: Sat, 11 Jul 2026 01:45:58 +0300 Subject: [PATCH 01/22] test(watch): characterize Lance atomic versions, graph COW snapshot, warm model reuse MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Three heavy-gated characterization tests (JAVA_CODEBASE_RAG_RUN_HEAVY=1) that lock in the concurrency pillars the `jrag watch` daemon assumes (design §4.7/§9): - test_lance_atomic_versions: a fresh lancedb.connect after a cocoindex catch-up sees a strictly newer atomic version with the new file's chunks fully present; a handle opened before the write keeps a consistent (pre-write) snapshot. - test_graph_cow_snapshot (load-bearing): a read-only reader on a file COPY of code_graph.lbug is isolated from run_incremental_graph writing the original (returncode 0, no single-writer conflict); the sidecar keeps the pre-write node count while the original grows. - test_warm_model_reuse: _get_sentence_transformer returns one process-wide singleton, reused across calls and by search_v2. Key characterization findings recorded in docstrings: - Lance version delta per catch-up is ~+4 (catch-up + serialized optimize), not +1; the pillar only needs monotonic atomic growth. - LadybugGraph.meta()["counts"] is NOT a reliable node count across an incremental rebuild (phantom resolution offsets new nodes: summed total 88->88 while the real :Symbol count grew 88->93); tests use a direct MATCH query instead. - LadybugGraph.reset_for_path does not exist yet (Task 6 adds it); singleton is reset manually as the existing heavy e2e tests do.

The daemon's design (see +``docs/specs/2026-07-11-watch-mode-design.md`` §4.7/§9) rests on three pillars, +locked in here so that Tasks 6 (warm resources) and 9 (reindex watcher) can rely +on them. Where reality diverges from the design's expectation, the divergence is +recorded in the test's docstring and the assertion tracks reality — we never +silently change engine behavior. + +The three pillars: + +(a) **Lance atomic versions** — Lance commits are atomic per version. A fresh + ``lancedb.connect`` per query returns a consistent old-or-new view during/after + a cocoindex write, never partial, never blocked. (``test_lance_atomic_versions``) + +(b) **Ladybug graph COW snapshot isolation** — the ``ladybug`` package (a kùzu + wrapper) has no transaction API and is single-writer. Graph builds run as + SUBPROCESSES (``run_incremental_graph``). A read-only reader on a file COPY + (sidecar) keeps returning pre-write data while the subprocess writes the + ORIGINAL, and the two never conflict (different files). This is the + load-bearing finding: it is why the daemon can serve graph reads during a + reindex by copying ``code_graph.lbug`` to a sidecar. (``test_graph_cow_snapshot``) + +(c) **Warm model reuse** — ``mcp_v2._get_sentence_transformer`` caches a single + ``SentenceTransformer`` in a module global and reuses it across calls in one + process (the entire warmth win).

Each handler becomes 'payload = _payload(args, cfg, graph); render(payload, args)' — rendering byte-identical to before. - callers_payload/callees_payload/flow_payload carry the full assembly verbatim, including the three ad-hoc folds: callers EXPOSES-inbound, callees CLIENT-role HTTP_CALLS, and flow inbound/outbound merge. - search_payload/find_payload/inspect_payload wrap the *_v2 (or find_by_name_or_fqn) backend call. - Resolve/guard/validation failures raise PayloadError(env, rc); the handler renders the carried Envelope, so error output is byte-identical too. New golden-output equivalence tests (tests/jrag/test_read_payloads.py + tests/jrag/golden/) prove byte-identity for 9/10 commands; inspect is pinned by canonicalized JSON because its edge_summary dict key order is pre-existing non-deterministic in describe_v2 (verified on unmodified HEAD). All three folds are exercised by the golden fixtures.

Adds LadybugGraph.reset_for_path classmethod (clears the cached singleton on None or matching path) so WarmResources can force the next get() to reopen.

On daemon success the payload is reconstructed into the same object the cold core returns (model_validate for the pydantic *Output models; SymbolHit(**row) rebuild for find query-mode rows); on DaemonUnavailable / DaemonError it cold-falls-back to the identical _payload core via _load_graph (a cache hit on the already-loaded singleton). The 6 jrag read handlers (search/find*/inspect/callers/callees/flow) acquire their payload via get_payload("", vars(args), cfg, cold_core=_payload); only the payload-acquisition line + a lazy import per handler changed -- render and rc logic are untouched, so the cold path stays byte-identical (Task 5 golden suite 15/15 unchanged).

Inline floors/validation: debounce_ms >= 100, backend in {auto,watchdog,polling}, poll_interval_ms >= 200 — out-of-range values fall back to the default with a one-line stderr warning. _pick_int gains an optional cli_val kwarg (default None) mirroring _pick_str, so the CLI-override tier flows through the helper; existing callers untouched.

The serving-path shutdown ends with os._exit(0) (mirrors _console_script_main) to dodge the pyarrow/lance worker-thread SIGABRT once a search has loaded lancedb in-process. Early-failure paths (lock held / model load) return 2 normally (no lance threads yet). - jrag.py: `watch` subparser (parents=_core_parser, no auto-scope) with --detach/--stop/--status/--debounce-ms/--backend; `_cmd_watch` + helpers. --status/--stop read ProjectLock.read_holder only (never acquire the lock). --detach spawns `python -m java_codebase_rag.jrag watch` detached (setsid + redirected stdio) and waits for is_daemon_alive. `--debounce-ms`/`--backend` plumbed through _resolve_cfg. - tests/watch/test_daemon.py: 10 lifecycle tests (stubbed warm/watcher in a subprocess so the real os._exit shutdown runs outside pytest) + a heavy-gated golden IPC test proving `jrag search` over the socket is BYTE-IDENTICAL to the cold path, with a _load_graph spy proving the hot path was actually served. Two integration fixes found + resolved by the tests: 1. Stale socket before bind: the daemon acquires the lock BEFORE server.start, so the server's `read_holder is None` stale-socket guard is inert (it sees its own pid). The daemon now clears its own stale socket before bind (it holds the exclusive lock, so it owns the path). 2. `python jrag.py` as a script shadows stdlib `ast` with java_codebase_rag.ast (inspect -> ast.NodeVisitor crashes). Detach now invokes the daemon via `python -m java_codebase_rag.jrag`. queries_served left at 0 for v1 (wiring a count out of WatchServer is out of this task's commit surface and the brief marks it optional).

Vectors run via `run_cocoindex_update` (cocoindex memo catch-up — changed files only); graph via `incremental_rebuild` (same full-rebuild fallbacks as `increment`). +4. On commit, any in-process read caches the daemon holds are invalidated so the next query reflects the newly committed state. (The embedding model itself is unchanged — same `SBERT_MODEL` — so `_st_model` is not reloaded.) + +### 4.6 Lifecycle & locking + +- A pidfile + exclusive `flock`, keyed to the resolved index dir, prevent a second watcher **or** a concurrent manual `java-codebase-rag increment` from corrupting the project. If the lock is held, `jrag watch` reports the holding pid and exits non-zero. +- `flock` is released by the OS on holder death, so a `kill -9` leaves no stuck lock; the pidfile/socket are reconciled on next start and by `--stop`/`--status`. +- Shutdown reuses the `os._exit` teardown discipline (the one-shot CLI already needs it to avoid a pyarrow/lance worker-thread crash at interpreter finalization) — applied once, at process end. + +### 4.7 Concurrency model — "searches never wait, never see partial" + +Verified against the installed engines during planning (see §9): LanceDB commits are atomic per version, and `ladybug` (a kùzu wrapper) has **no transaction API** — every statement autocommits and a `Database` is single-writer. The design therefore differs by store: + +- **Lance (vectors):** each query connects fresh (`lancedb.connect`, cheap) and reads the latest **committed** version. cocoindex catch-up writes new versions atomically, so a query sees old-or-new, never partial, never blocked. No handle caching or `checkout` is required for the normal path. +- **Ladybug graph:** no transactions means a concurrent reader on the same file could observe a partially-applied incremental write, and the single-writer rule means the graph build must run as a **subprocess** that owns the file. To honor never-wait/never-partial, the daemon takes a **copy-on-write file snapshot** of `code_graph.lbug` around each graph reindex: before spawning the build, it copies the file to a sidecar and serves graph reads from the sidecar (old, consistent) for the duration; on success it drops the sidecar and reopens the updated original. Graph queries during a reindex thus hit the pre-write snapshot — never blocked, never partial. (Fallback if snapshotting proves unreliable on some filesystems: briefly quarantine graph reads for the duration of the write — a wait of seconds, only for graph queries, only during a graph reindex. Process crashes mid-write are still covered by the existing `.graph_increment_in_progress` marker + full-rebuild fallback.) + +### 4.8 IPC contract + +- **Socket path:** per-user runtime directory containing `watch-.sock` and `watch-.pid`, where `` is the first 12 hex chars of SHA-256 of the absolute index-dir path. Stable per project, distinct across projects, machine-local. (Runtime dir: `$XDG_RUNTIME_DIR/jrag/` on Linux; `$TMPDIR`-/`~/Library/Caches/jrag/`-based on macOS.) +- **Transport:** newline-delimited JSON (one request per line, one response per line) over `AF_UNIX`. +- **Request:** `{"v":1,"cmd":"","args":{…}}` — `cmd` ∈ {`search`,`find`,`describe`,`callers`,`callees`,`flow`,`inspect`}; `args` mirror the CLI flags of that command. +- **Response (success):** `{"v":1,"ok":true,"result":}` where `` is the same structure the cold path produces (so rendering is shared). +- **Response (error):** `{"v":1,"ok":false,"error":{"kind":"","message":"…"}}`. +- **Version field `v`:** a CLI/daemon whose `v` differs cold-falls-back with a one-line advisory to restart `jrag watch`. + +### 4.9 Config (new `watch:` block in `.java-codebase-rag.yml`) + +```yaml +watch: + debounce_ms: 1500 # coalesce editor burst-saves before reindexing + backend: auto # auto | watchdog | polling + poll_interval_ms: 2000 # polling-fallback cadence +``` + +- Warm query needs no knob — every read command uses the daemon if up, else cold. No new environment variables are introduced; configuration is YAML plus the `jrag watch` flags above. + +## 5. Error handling + +| Failure | Behavior | +|---|---| +| Daemon crash mid-reindex | Existing `.graph_increment_in_progress` marker → full-rebuild fallback next run (unchanged). | +| cocoindex/tree-sitter binary missing | Same pre-spawn `status=failed` stub the lifecycle CLI emits. | +| Stale pidfile / dead socket (`kill -9`) | Read commands, `--status`, `--stop` detect a dead pid → remove socket → cold fallback or clean exit. `flock` auto-released by the OS. | +| Lock held by another process | `jrag watch` reports the holding pid and exits non-zero; never fights. | +| Model/embedding load failure | Daemon logs and exits non-zero; CLI cold path still works. | +| CLI/daemon `v` mismatch | CLI cold-falls-back with an advisory to restart `jrag watch`. | +| Watch error on a subtree (permissions) | Log and keep watching the rest; do not crash. | + +## 6. Testing + +Existing ritual applies (`rm -rf tests/*/.java-codebase-rag*`, temp index, editable install). + +- **Unit:** debounce/coalesce window; per-type routing (java → vectors+graph; sql/yml → vectors-only); socket-path derivation (stable per project, distinct across projects); pidfile/`flock` acquire and stale-detection; cold fallback when no socket; backend auto-selection (watchdog vs polling). +- **Integration** (gated like the existing heavy e2e tests): daemon on a temp index → touch a `.java` → assert `incremental_rebuild` ran (`FileHashTracker` hashes / counts changed) and a concurrent `jrag search` returns a consistent old-or-new result; assert a second `jrag watch` is refused by the lock; assert `--stop` drains and removes the socket. +- **Concurrency correctness (key risk test):** concurrent graph reads during an incremental write never observe a partial graph — validates the transaction/RWMutex decision. +- **Warm path:** assert the daemon serves a search without re-importing torch — i.e. `run_search` receives the injected warm `model=` (mock the cache) rather than constructing a new `SentenceTransformer`. + +## 7. Documentation & shipped-artifact impact + +- `docs/JAVA-CODEBASE-RAG-CLI.md` — new `jrag watch` section (foreground / `--detach` / `--stop` / `--status`), the "run it while you code" workflow, and the cold-fallback guarantee. +- `docs/CONFIGURATION.md` — the `watch:` YAML block. +- `docs/ARCHITECTURE.md` — daemon on the read path and a new watch path; note it is the MCP server's warm-cache posture, served to the CLI. +- `docs/DESIGN.md` — watch as a first-class surface; the non-goals below. +- `skills/` / `agents/` — the `explorer-rag-cli` skill/subagent gets a "start `jrag watch` once per session for fast + fresh queries" tip. These ship verbatim; the repo is the source of truth. + +## 8. Non-goals + +- Not a boot/persistent service — no launchd/systemd/autostart; explicit `jrag watch` only. +- Not multi-project per process — one daemon per resolved index dir. +- Not network/remote serving — Unix socket, local only; no TCP, no auth. +- Not a replacement for the cold path — every read command still works without the daemon. +- Not new search semantics — identical backends (`search_v2`, `LadybugGraph`); only transport differs. +- Not for the MCP surface — it is already long-running and warm; watch targets the `jrag` CLI. + +## 9. Verified during planning + +1. **LadybugDB transactions — not available.** The `ladybug` package (kùzu wrapper) exposes no `begin`/`commit`/`rollback`; every `conn.execute` autocommits, and a `Database` is single-writer. Atomic graph writes are impossible at the DB level, so the design uses a file-level COW snapshot around each graph reindex (§4.7). Process crashes mid-write remain covered by the existing `.graph_increment_in_progress` crash marker + full-rebuild fallback. +2. **LanceDB versioned reads — available and sufficient.** Lance commits are atomic per version; a fresh `lancedb.connect` per query returns a consistent old-or-new view during a cocoindex write, so no version-pinning/`checkout` is needed for the normal path. (`table.checkout(v)` exists as an escape hatch but mutates shared table-object state, so it is not used by default.) + +## 10. Known limitations & follow-ups + +1. **CI skips the load-bearing tests.** `.github/workflows/test.yml` sets `JAVA_CODEBASE_RAG_RUN_HEAVY=0`, so the heavy watch tests are skipped in CI — they run only locally with `JAVA_CODEBASE_RAG_RUN_HEAVY=1`. These are the tests that prove the core guarantees: the golden IPC byte-identity suite (now 6: `search` + `find`/`inspect`/`callers`/`callees`/`flow` over the real socket vs cold), the COW snapshot characterization (3), and the warm-reuse + snapshot lifecycle tests (5) — 14 total. The rest of `tests/watch/` (lifecycle, lock, protocol, client reconstruction) is lightweight and runs in CI. **Follow-up:** add a heavy CI job (or nightly) so the byte-identity and COW guarantees are gated, not just locally verified. + +2. **Client-side graph load may transiently error during a graph reindex.** The `jrag` read handlers call `_load_graph_or_error` (client-side, opens the ORIGINAL graph) before `get_payload` dispatches to the daemon. During a graph reindex the daemon serves reads from the sidecar copy, but the client-side open of the original races the subprocess writer; if kùzu refuses a read-only open mid-write, the command surfaces a transient `rc=2` for the ~seconds of the reindex. This is never partial data — the served result always comes from the daemon's sidecar, and a stale-graph error is the honest signal. V1-acceptable. **Follow-up:** when `is_daemon_alive`, skip the client-side graph load and let the daemon's `ERR_STALE_INDEX` drive the error path (the client-side load is only needed for the cold path's own pre-`get_payload` work, e.g. auto-scope defaults). + +## TL;DR + +`jrag watch` runs one warm process per project that watches files → runs the cheapest incremental reindex on change (reusing existing change detection), and serves every `jrag` read command over a Unix socket using a pre-loaded embedding model and held-open Lance/Ladybug connections — eliminating the per-call cold start. Reads never block and see old-or-new snapshots, never partial (Lance versioning + graph transactions, with a sub-millisecond-commit RWMutex fallback). A pidfile/`flock` adds the mutual exclusion the codebase currently lacks. With no daemon running, every command behaves exactly as it does today. diff --git a/src/java_codebase_rag/watch/warm.py b/src/java_codebase_rag/watch/warm.py index 6c49fed..3686053 100644 --- a/src/java_codebase_rag/watch/warm.py +++ b/src/java_codebase_rag/watch/warm.py @@ -16,6 +16,7 @@ import logging import shutil +import threading from pathlib import Path from java_codebase_rag.config import ResolvedOperatorConfig @@ -32,50 +33,73 @@ class WarmResources: returning the same instance across calls is the warmth win. ``graph()`` returns the snapshot reader when a snapshot is active, else the original reader.

Master #430 also enriched route/symbol node rendering (name/method/path/ framework/resolved/file on routes; name/file on symbols), so regenerate the 3 affected byte-identity goldens (callers_route, flow_merge, find_filter); the other 8 goldens are byte-identical. Cold==daemon byte-identity re-verified (tests/watch 116, incl. all 6 IPC goldens).

6ef2ecd42bb5630c391fba97ce4d3d1962a202ca Mon Sep 17 00:00:00 2001 From: Dmitry Teryaev Date: Sat, 11 Jul 2026 14:44:36 +0300 Subject: [PATCH 22/22] fix(ci): sync install_data, heavy-gate golden test, skip watch on Windows MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Three CI failure classes after the rebases onto master: 1. install_data out of sync (all platforms). The deployed skill/agent copies (src/.../install_data/{skills,agents}/explorer-rag-cli) lacked the ``jrag watch`` tip added to the dev source — test_install_data_sync caught the drift. Re-run scripts/sync_agent_artifacts.py (never hand-patch deployed copies). 2. test_golden_output_byte_identical cross-platform fragility (callees_symbol / flow_merge on linux+windows; search on intel-mac). The e2e golden builds a real index and byte-compares CLI stdout captured on one platform, but graph-traversal edge order follows indexing file-traversal order (OS- dependent) and the search golden relies on the Lance table being absent (index-dir nondeterminism). Gate it behind JAVA_CODEBASE_RAG_RUN_HEAVY=1 (same idiom as test_lancedb_e2e) — it's a LOCAL regression guard, not a portable CI check. CI still covers the cold read path via tests/package/*; warm==cold byte-identity is covered (heavy) by tests/watch/test_daemon.py. The in-process Layer 2 tests stay in CI (only the e2e golden is gated). 3. tests/watch on Windows. jrag watch is Unix-only by design (AF_UNIX sockets + fcntl flock; watch/lock.py raises WatchUnsupportedPlatform). The tests exercise those primitives directly, so add tests/watch/conftest.py that skips the whole tree when fcntl is unavailable (the product's own gate).
