Zeren Wang	a58ab484a6	feat(projects): Projects MVP Phase 2 — instructions, document shelf, promotion, trash (#5443) ... * feat(projects): Projects MVP Phase 2 — instructions, document shelf, promotion, trash Implements docs/superpowers/specs/2026-09-12-projects-mvp-phase2-design.md (issue #5160, tracker #5129) in the slice order of the spec's §16. Slices: - A: ProjectsConfig + write-time 422 UTF-8 byte cap; PROJECT_CONTEXT_KEY admission pinning (both server-owned sets + worker hoist); latest-only request-scoped <project> block via DynamicContextMiddleware wrap_model_call/awrap_model_call (idempotent reassembly, reserved ID prefix + marker + provenance, never persisted); journal audit fingerprints; Instructions tab. - B: ProjectDocumentRow + migration 0023; ProjectDocumentRepository with locked check-and-set; hash-qualified immutable shelf storage with Paths helpers; upload/list/content/delete-to-trash routes; project delete trashes the shelf in-transaction; request-scoped bounded <documents> index with honest count/shown + actionable overflow note; list_project_documents/read_project_document tools registered only on pinned runs; PAT allowlist + drift guards; blocking-IO anchors. - C: shared thread-upload ingestion service (uploads router refactored to parity); POST from-thread with provenance; attach-to-thread with lock-staged copy (archived source allowed); read-only thread-files view with per-group truncation reporting. - D: restore (restored/merged/not_found/no_target/content_missing; no file moves), purge (continuous row lock across unlink/delete/commit, retryable on FS errors), retention sweep (lazy + startup, 24h orphan guard, row-side reconciliation never deletes). - E: Documents tab (shelf + conversation-files browser, provenance, archived banner, content-missing rows), /workspace/trash route, sidebar entry, composer attach handoff, i18n (en-US/zh-CN), e2e mocks + specs. Review hardening folded in (10 rounds, all with tests): - force active shelf content (HTML/XML family) to download; nosniff on artifact + content responses; unified unsandboxed-iframe PDF preview (fixes the pre-existing Chromium sandbox blank in the artifact viewer) - scope document trash to the URL project under the document lock - atomic no-overwrite filename reservation for ALL ingestion (seeded claims + os.link commit with suffix retry; same-name re-upload now unique-names instead of replacing); hidden staging only, no visible placeholders; lease cleanup on setup failure - serialize conversion under the document lock with post-lock active revalidation; drain locked filesystem work on cancellation; preserve bytes when an insert's commit state is uncertain (including trashed rows) - original-integrity checks before serving text or cached conversions; content_missing surfaced in list responses (UI reads the flag, no 409-probe); downloads always serve original bytes - bounded streaming document reads with cached char counts; shelf limits declared in middleware release identity - thread-root confinement for from-thread sources; config fallback rejects fractional/infinite values; composer counts staged attachments; pending attachments persist until submission or removal; in-flight instruction/rename edits survive save refetches; shelf and trash pagination; conversation-file and thread-files pages stay subscribed to refetches Docs: README/README_zh, backend API.md/ARCHITECTURE.md, AGENTS.md contracts, config.example.yaml projects block. Review follow-ups (head b4807477 → this revision): - The trash retention sweep is split so repeated lazy triggers stay bounded: the indexed expiry purge still runs on every trigger (GET /api/trash/documents, POST /api/trash/purge) while the O(all rows + all files) reconciliation is throttled to one run per user per 15 minutes (process-local, per-user window). The startup sweep now runs as a background task instead of blocking gateway readiness, and shutdown awaits it (bounded). - The export scrub (stripInternalMarkers) is fence- and indentation-aware like the render path, so a pasted, fenced <project>/<documents> snippet survives markdown export while real injected blocks (never fenced) are still removed. Fence regexes moved to a dependency-free leaf module to avoid the messages↔streamdown import cycle. - The artifact viewer's PDF iframe no longer carries an added title attribute (the upstream e2e contract locates it via :not([title])), and the upstream artifact-preview spec now pins the new contract: PDFs render unsandboxed, images keep sandbox="". * fix(projects): round-2 review — cancel an overrun trash sweep, restore the PDF frame title - Shutdown cancelled only the shield around the background startup sweep, so an all-users reconciliation that outlived the 5s budget kept walking rows and files while the document repo and DB engine were disposed underneath it. The wait now lives in `_shutdown_startup_trash_sweep`, which cancels the task and drains it before worker exit: the shield keeps the wait bounded, the cancel makes it final (CancelledError lands at the sweep's next await, and `_run_startup_trash_sweep` only catches `Exception`, so nothing swallows it). - The browser-preview iframe lost `title={getFileName(filepath)}` in the previous fix round, leaving the PDF frame without an accessible name while its siblings keep theirs. Restore it (WCAG frame titles), assert it in the DOM test, and anchor the e2e on `iframe[title="report.pdf"]` instead of `iframe:not([title])`. * fix(projects): round-3 review — report the sweep's late finish, not a phantom cancel `Task.cancel()` returns False when the sweep already finished inside the window between the deadline firing and the cancel, so the shutdown log claimed a cancellation that never happened. Branch on that outcome: the warning stays for a real cancel, a late finish is logged at info, and both paths still reap the task before worker exit. * fix(projects): round-4 review — make Empty trash delete what it confirms `POST /api/trash/purge` only ran the retention sweep, and the sweep's candidate selection is age-gated, so a freshly trashed document survived "Empty trash" even though the confirmation promises that every listed document is permanently deleted. With one trashed row the route answered `{"purged": 0}` and left it in place; `GET /api/trash/documents` sweeps expired rows before listing, so the visible rows were normally ineligible for the action by construction. Empty trash now drives `purge_all_trashed`: the caller's trashed rows (`list_all_trashed`, no age filter) each go through the same guarded, row-locked `purge` as the single-document delete — bytes first, then the row, in one transaction — so a row restored mid-flight is skipped instead of force-deleted, and an unlink failure rolls that row back and answers 500 with a retryable message. Retention expiry stays where it was: the sweep's `purge_candidates` is now the only age-gated selection, and the lazy retention sweep still runs on the listing and at startup. Tests: the router suite replaces the retention-gated expectation with the reviewer's repro (fresh row purged, bytes unlinked, shelf and other users' trash untouched, a failing unlink stays retryable and 500); a blocking-I/O anchor drives the new entry point through the offload; the mocked e2e covers the action end to end; a new real-backend spec performs it against the real gateway and re-reads `GET /api/trash/documents`. README, API, ARCHITECTURE and the phase-2 design docs (en+zh) state the age-independent contract.	2026-09-16 18:46:18 +08:00
Zeren Wang	5951c89b5b	feat(projects): project workspaces with scoped chats and thread membership (#5265) ... * feat(projects): project workspaces with scoped chats and thread membership Backend: - projects table model and migration; fail-closed ProjectRepository with ownership checks, CRUD/archive/restore/delete router, and atomic thread move between projects - threads_meta.project_id column exposed as reserved deerflow_project_id metadata; project-aware thread create/search with pagination bounds and membership echoed in create responses - first-run admission assigns the project only at genuine first run, seeded at write time and dropped when invalid; serialized against project deletion and thread assignment - branch creation inherits the source thread's project membership (an archived/deleted project degrades the branch to unassigned instead of failing the request) Frontend: - projects data layer, thread move API, and sidebar projects section with flat/grouped modes, archived-project threads, and stable virtual-list offsets - project detail page with project-scoped new chat (/workspace/chats/new?project=) and paginated thread list - move-to-project thread menu, new-project dialog, archived-project gates - project-scoped new chats pre-create the thread with membership before the first submit or /goal set, so runs never proceed outside the project - goal-set preparation is fenced against conversation switches: a stale continuation is dropped instead of saving the goal or launching the abandoned submission on the newly opened conversation - project thread lists join thread lifecycle invalidations (stop, pin) so an open project page never keeps stale titles, recency, or pagination * fix(chats): keep archive undo toast when the sidebar row unmounts The archive success toast was fired from per-mutate callbacks passed to mutation.mutate. React Query drops those handlers when the observer component unmounts before the mutation settles; archiving the open chat removes its sidebar row mid-flight, so the undo toast never appeared and the e2e archive-undo test timed out waiting for it. Move the success/error handlers to the mutation level (useArchiveThread options, same pattern as useMoveThreadToProject) where callbacks are delivered even after the originating row unmounts. * fix(projects): pin project thread listing contract and exclude archived chats GET /api/projects/{id}/threads returned the thread store row verbatim (list[dict], no response_model): user_id/assistant_id leaked, any future ThreadMetaRow column would auto-leak, and the OpenAPI schema was empty. Return a narrow ProjectThreadResponse (the exact fields ProjectThread declares) with the same metadata secret redaction the surrounding thread endpoints get from _MetadataRedactingResponse. The listing also ran search() without the archived filter, so a retired chat rendered as a normal row on the project page while the sidebar hid it. Search archived=False to mirror the sidebar's archived:false lists; restore stays on the global Archived tab. Both regressions pinned by new router tests: wire-shape allowlist and archived-member exclusion. * docs(migrations): record the 0019/0020 chain against the bootstrap reservation The tree now chains 0018 -> 0019_projects -> 0020_threads_meta_project_id, so migrations/AGENTS.md was stale twice over: the revision index stopped at 0018 and the rolling-forward section still claimed the tree 'deliberately remains at 0018'. Document the new head and record the intentional numeric-prefix reuse of 0019: 0019_projects is in-chain while 0019_thread_incarnations stays the reserved, allowlisted out-of-tree rollout id. The owning rollout revision must re-parent onto this tree's head when it merges so alembic never sees two heads off 0018; bootstrap.py now cross-references that note next to _FORWARD_COMPATIBLE_REVISION. * fix(chats): invalidate project thread lists on archive/restore useArchiveThread refreshed the infinite sidebar cache, threads/search and the per-thread metadata cache but not the project-scoped list ([...PROJECTS_QUERY_KEY, 'threads', id]) this PR adds — the one thread mutation not wired to that key, after usePinThread, useRenameThread, useDeleteThread, useMoveThreadToProject and invalidateStoppedThreadCaches. An archive from a sidebar row while a project page is open therefore left the archived chat rendered as a normal row until remount (and undo left it missing). Invalidate the prefix in the mutation-level success handler. Regression test asserts the project-list prefix is invalidated on success. * fix(projects): fetch project discovery only in grouped sidebar mode RecentChatList mounted two useProjects queries per sidebar render, but knownProjectIds is consumed only by the grouped-mode exclusion filter; in the default flat mode every page load paid two GET /api/projects?status= round trips for data nothing read. Gate both queries on grouped mode — GroupedProjectList fetches the same keys when the toggle is on and TanStack dedupes the observers. Also set retry: false on useProject: a deleted or foreign project 404s deterministically, and the page renders a dedicated not-found state for it, so the default 1s/2s/4s retry backoff kept deep links in 'loading' for ~7s before that state appeared. Matches useThreadMetadata / useThreadTokenUsage. * fix(threads): fail closed on project-scoped create in memory mode MemoryThreadMetaStore.create accepted project_id and silently ignored it, making memory mode the one membership path that fails open: POST /api/threads with a project id returned 200 and the run started unassigned, violating the invariant that a run never proceeds outside the selected project (the SQL store raises ProjectNotAssignableError inside the insert transaction for the same request). Raise ProjectNotAssignableError whenever project_id is present so the router's existing 404 mapping applies, the frontend keeps the composer text for a retry, and memory mode behaves exactly like SQL mode. set_project already reports rejection; create now matches it. Store-level test (raises, nothing persisted, project filter stays empty, unscoped creates still work) plus a router-level test asserting the 404 and that no row is left behind. * fix(projects): window the project page thread list ProjectThreadsSection rendered every loaded page as a plain Link row, so a long-lived project accumulated unbounded DOM on the page's scroll surface: each load-more appended another 100 rows and every formatTimeAgo tick re-rendered the whole list. Reuse VirtualThreadList (now generic over any row shape with a thread_id), pointing its scroll parent at this page's ScrollArea viewport via the shared [data-slot="scroll-area-viewport"] selector used by /workspace/chats; under the 60-row threshold it falls back to the plain render, so small projects are unchanged. * fix(projects): restore row dividers and pin them with a render test The row class template literal concatenated transition-colors directly with the conditional border-b token, so non-final rows rendered the invalid class 'transition-colorsborder-b' and lost both the divider and the transition. Compose the row classes with cn() and a boolean guard instead. The section moved out of page.tsx into a testable component so the row markup finally has coverage: a DOM test asserts every row except the final data row carries border-b (index-based, not last: — correct under virtualization where the last mounted row is not the last data row), and the untitled fallback plus load-more button render for a partial page. * fix(projects): validate forward schemas and fence membership reads	2026-09-08 17:00:26 +08:00
Michael	4791e94a73	feat(gateway): add /health/ready readiness probe backed by the database (#5166) ... * feat(gateway): add /health/ready readiness probe backed by the database ## Why GET /health only proves the process is up: it returns 200 even when the persistence engine cannot reach the database. Orchestrators already treat it as a readiness gate (docker-compose.yaml marks the gateway service healthy and nginx depends_on service_healthy), so a DB outage or a still-migrating Postgres leaves the stack 'healthy' while every request fails. ## What changed - New GET /health/ready endpoint: bounded SELECT 1 against the existing persistence engine (deerflow.persistence.engine.get_engine) with a 2s timeout. - Response is 200 {'status': 'ready', 'database': 'ok'} when reachable, 503 {'status': 'degraded', 'database': 'unreachable'} when the probe fails, and 200 ready with database=not_configured for backend=memory (nothing to probe). - GET /health is unchanged (pure liveness), and /health/ready is public through the existing /health auth whitelist. - docker-compose.yaml gateway healthcheck now polls /health/ready so service_healthy reflects database reachability. - Documented both endpoints in backend/app/gateway/AGENTS.md. ## Surface area - [x] Backend API - new GET /health/ready endpoint under backend/app/gateway - [x] Sandbox / Docker - gateway healthcheck in docker/docker-compose.yaml now gates on readiness - [ ] Frontend UI / Agents / Skills / Dependencies - [x] Default behavior change - existing /health unchanged; the prod compose healthcheck is stricter (503 while the database is unreachable) ## Validation - New unit tests in backend/tests/test_gateway_health.py cover ok / unreachable / not_configured probe results and the 200/503 payload mapping (6 passed). - app.gateway.app imports cleanly and registers both /health and /health/ready. - ruff check + ruff format clean. ## AI assistance **Tool(s) used:** Codex (coding agent) **How you used it:** design, implementation, and unit tests produced with AI assistance; reviewed before commit. - [ ] I've read and understand every line of this change and take responsibility for it — it's not unreviewed AI output. * fix(helm): point the gateway readiness probe at /health/ready ## Why Review on #5166 (willem-bd, P1): the chart still probed /health for readiness, so Kubernetes marked the pod ready and routed traffic while the database was unreachable - exactly the failure mode /health/ready was added to catch. ## What changed - deploy/helm/deer-flow/templates/gateway-deployment.yaml: readinessProbe httpGet.path now hits /health/ready (DB-backed, 503 while the database is unreachable). The liveness probe stays on /health. ## Verification - One-line path change inside the existing readinessProbe block; git diff confirms only the readiness path changed (liveness untouched). ## AI assistance **Tool(s) used:** Codex (coding agent) **How you used it:** implemented the reviewer-requested probe path change; reviewed before commit. - [ ] I've read and understand every line of this change and take responsibility for it — it's not unreviewed AI output. * fix(gateway): readiness probe also checks the effective checkpointer/Store backend ## Why Follow-up review on #5166 (willem-bd, P1): get_engine() only represents the ORM backend selected by `database:`. The legacy `checkpointer:` section takes precedence for the LangGraph checkpointer and Store, so a split configuration (a local SQLite/memory `database:` with `checkpointer.type: postgres`) could report 200 while the PostgreSQL backend agent runs depend on was down. ## What changed - GET /health/ready now probes both persistence halves: the ORM engine behind `database:` (unchanged) and the effective LangGraph checkpointer/Store backend resolved with the runtime's own rule (legacy `checkpointer:` config, otherwise derived from `database:`), for memory/sqlite/postgres backends. - The payload gains a `checkpointer` field with the same ok / not_configured / unreachable vocabulary as `database`; 503 degraded is returned when either probe is unreachable. - Probes are bounded by the existing 2s timeout: sqlite via aiosqlite SELECT 1 on the resolved path, postgres via a bounded psycopg AsyncConnection SELECT 1 on the DSN with the configured search_path. A missing driver for a configured backend degrades readiness (the runtime could not run either). - Documented the two-probe semantics in the endpoint docstring and backend/app/gateway/AGENTS.md. ## Verification - New tests: healthy ORM engine + unreachable legacy checkpointer backend -> 503 degraded with database: ok / checkpointer: unreachable; checkpointer probe mapping for memory/sqlite(postgres missing-driver) backends; existing payload tests now pin the checkpointer field. - cd backend && python -m pytest tests/test_gateway_health.py: 11 passed. - app.gateway.app imports cleanly; ruff check + ruff format clean. ## AI assistance **Tool(s) used:** Codex (coding agent) **How you used it:** design, implementation, and unit tests produced with AI assistance; reviewed before commit. - [ ] I've read and understand every line of this change and take responsibility for it — it's not unreviewed AI output. * fix(gateway): bound /health/ready to one deadline and probe the startup checkpointer snapshot ## Why Second round of review on #5166 (zhfeng P1/P2, willem-bd P1/P1/P2). Three correctness issues remained in the readiness endpoint: - The database and checkpointer probes ran sequentially, each allowed 2s, so a healthy response could take almost 4s - past Kubernetes' 1s default readinessProbe timeout and inside Docker's 3s client timeout. A slow but healthy backend could make every replica unready. - The checkpointer probe re-resolved process-wide, hot-reloaded configuration per request, while app.state.checkpointer/store are built once from the startup_config snapshot in langgraph_runtime(). After a live config edit the endpoint could probe a backend the running gateway does not use, and a resolution failure was swallowed into None -> not_configured -> 200. - The SQLite probe opened the path with aiosqlite.connect(), which creates the file when missing: a deleted checkpoint database was silently resurrected as an empty file and reported ok instead of surfacing the outage. ## What changed - backend/app/gateway/health.py: the two probes now run concurrently beneath a single endpoint-wide deadline (_READINESS_DEADLINE_SECONDS=3.0) so a healthy response completes within one probe window (~2s), never the sum of both. A probe that overruns the deadline degrades the endpoint instead of hanging. - langgraph_runtime() now records the checkpointer/Store config resolved from the same startup_config snapshot its checkpointer/store singletons are built from (app.state.checkpointer_config); /health/ready probes that snapshot and never re-resolves hot-reloaded config. resolve_checkpointer_config() returns None on resolution failure and the endpoint fails closed (503, checkpointer: unreachable) instead of reporting not_configured. - The SQLite probe opens disk-backed paths with the non-creating mode=rw URI flag, so a missing database file stays missing and yields unreachable; in-memory forms (:memory:, file:...mode=memory) have nothing external to probe and report not_configured like the memory backend. - Orchestrator timeouts now sit above the endpoint bound: Helm readinessProbe gains timeoutSeconds: 5 (Kubernetes default is 1s) and the docker-compose gateway healthcheck client timeout moves from 3s to 5s. ## Verification - New regression tests: concurrent probes keep total elapsed time within one probe window; a probe ignoring its budget trips the endpoint deadline to 503; missing SQLite file stays absent and yields unreachable; in-memory SQLite forms map to not_configured; missing startup snapshot / config resolution failure fail closed to 503; resolve_checkpointer_config() raising is covered. - cd backend && python -m pytest tests/test_gateway_health.py: 21 passed; tests/test_gateway_docs_toggle.py and lifespan/shutdown gateway suites pass. - ruff check + ruff format clean on all changed files. ## AI assistance **Tool(s) used:** Codex (coding agent) **How you used it:** implemented the reviewer-requested concurrency/deadline, startup-snapshot probing, fail-closed resolution, and non-creating SQLite probe; reviewed before commit. - [ ] I've read and understand every line of this change and take responsibility for it — it's not unreviewed AI output. * fix(gateway): serialize connection-opening readiness probes behind a strict gate ## Why Review on #5166 (willem-bd, P1): every request to /health/ready opened a new PostgreSQL connection in _probe_postgres_backend, outside both the ORM pool and the runtime checkpointer pool. The route is public through the /health auth prefix and nginx proxies /health/*, so concurrent unauthenticated requests could create an unbounded number of connections (each held for up to two seconds), exhaust PostgreSQL max_connections, and take down both normal traffic and the readiness probe itself. ## What changed - backend/app/gateway/health.py: connection-opening checkpointer probes (sqlite connect, postgres AsyncConnection.connect) now run inside a strict per-process gate - an asyncio.Lock cached per running event loop - so at most one probe connection can be in flight per worker process. Requests that queue behind the gate are still shed by the existing endpoint-wide deadline, so a flood cannot pile up new connections or open files. - Memory and unknown-backend decisions stay outside the gate; payload and probe semantics are unchanged. The serialization is documented in the module docstring and backend/app/gateway/AGENTS.md. ## Verification - New regression test: 8 concurrent readiness_payload() requests against an instrumented sqlite probe assert the maximum number of in-flight probe connections is 1 while every request still returns 200. - cd backend && python -m pytest tests/test_gateway_health.py: 22 passed; tests/test_gateway_docs_toggle.py and tests/test_gateway_lifespan_shutdown.py also pass on the merged main head. - ruff check + ruff format clean on all changed files. ## AI assistance **Tool(s) used:** Codex (coding agent) **How you used it:** implemented the reviewer-requested strict concurrency bound for the public readiness probe; reviewed before commit. - [ ] I've read and understand every line of this change and take responsibility for it — it's not unreviewed AI output.	2026-09-04 23:26:53 +08:00
Sunshine	bf740ffa90	feat(auth): add personal access tokens for programmatic API access (#5041) ... * feat(auth): add personal access tokens for programmatic API access (#4849) Backend-first implementation of the PAT contract from #4849: show-once dfp_ tokens bound to their owning user (AUTH_SOURCE_PAT, is_internal=false), digest-only storage (migration 0017), strict credential precedence (invalid Bearer is a 401, never cookie fallback), CSRF double-submit skipped only for Bearer requests while auth-endpoint origin checks still run, scopes intersecting the authz route permissions, session-auth-only PAT management and password changes, and throttled best-effort last_used_at stamps. * fix(auth): harden PAT scope boundary and schema parity from adversarial review Independent review of the initial draft found: (1) scopes only constrained the threads/runs permission axis while admin routes treated a PAT as its (possibly admin) owner — is_admin_user now rejects PAT callers outright since no scope grants admin capability; (2) the model declared a column UNIQUE constraint while migration 0017 created a named unique index, so downgrade failed on create_all-bootstrapped DBs — both now use the named unique index; (3) auth-disabled mode is an operator override and now stays ahead of the Bearer check so a stray Authorization header cannot 401 an E2E sandbox; plus wiring the previously-unused constants, bounding the last_used_at stamp cache, and four new tests (middleware-level expiry, expires_in_days, admin-capability rejection with session control, and the auth-disabled precedence). * docs(api): document personal access tokens for programmatic API access * fix(auth): close PAT security boundaries from review (default-deny routes, extension admin suppression) P1-1: scope intersection only constrains @require_permission routes, so undecorated mutation routes (DELETE /api/memory, POST /api/agents, Lark credential switching, channel config) accepted a PAT holding a single read scope. AuthMiddleware now enforces a default-deny route policy in auth/pat.py: PAT requests are admitted only to the thread/run lifecycle routes the v1 scopes govern; everything else answers 403 regardless of scopes. Session-cookie callers are unaffected. P1-2: the extension principal resolver projected is_admin/roles from the raw system_role, so an admin-owned PAT passed deerflow_extension_api.require_admin on contributed routes despite the documented no-admin guarantee. The projection is now PAT-aware and suppresses every admin signal for PAT callers, mirroring deps.is_admin_user. Both fixes carry regression tests (route outside policy 403 + session control; production resolver admin suppression), and API.md documents the default-deny boundary. * fix(auth): enforce PAT scopes on stateless run entry and harden decorator Follow-up hardening from an independent audit of the P1 fixes: - POST /api/runs/stream and /api/runs/wait were the only allowlisted run entrypoints without @require_permission, so a threads:read-only PAT could still start runs (same bug class as P1-1, now closed): both now carry @require_permission("runs", "create"). POST /api/threads and POST /api/threads/search gain threads:write / threads:read for the same reason. Authorization-disabled deployments see no change (the permission set resolves to all permissions). - require_permission now binds the wrapped signature to locate a positionally-passed request before injecting the test stub, fixing 'got multiple values for argument' on direct positional unit-test calls. - API.md: the intro PAT example used GET /api/models, which the new default-deny policy 403s — replaced with GET /api/threads; the default-deny route list now spells out method sets. Regression test: threads:read-only PAT is 403 on the decorated stateless entry while a runs:create PAT passes. * fix(auth): address review P2s (empty Authorization header, PAT name trimming, API example) - CSRFMiddleware treats an explicitly empty Authorization header as present (is None), so an invalid credential always reaches AuthMiddleware's uniform 401 instead of a CSRF 403 that varies by method/CSRF state. Regression: empty-header request dies at auth. - PATCreateRequest strips the name and rejects whitespace-only values before token generation; created names are stored trimmed. - API.md intro PAT example now uses the implemented POST /api/threads/search endpoint (GET /api/threads does not exist). - AGENTS.md trimmed back under the guidance soft budget after the upstream merge. * fix(auth): tighten PAT route policy to implemented methods only The allowlist admitted GET /api/threads, a method no router implements. Pre-authorizing a dead method weakens the default-deny boundary: a future GET collection route added without a permission decorator would become PAT-reachable without an explicit policy change. Restrict the rule to POST, fix the stale GET description in API.md's PAT constraints, and document the default-deny boundary accurately in the gateway AGENTS.md guidance (only the threads/runs allowlist is PAT-reachable; every other authenticated route 403s PAT callers). Audited every remaining rule against the mounted routers: all other method+path entries map to real routes. Regression: test_pat_policy_does_not_pre_authorize_unimplemented_methods. * test(auth): guarantee the negative digest test mutates the token token[:-1] + "X" is identical to the original whenever the generated token already ends in X (1/62), making the negative digest assertion fail intermittently. Choose the replacement character based on the existing tail so the mutated token always differs. * fix(auth): require runs:cancel for cancel-then-stream requests stream_existing_run is gated at runs:read so action-less stream joins work with read-only credentials, but its ?action=interrupt|rollback branch cancels the run — a separate permission. A runs:read-only PAT passed both the PAT route policy and the route decorator and could interrupt or roll back an active run, bypassing the runs:cancel scope. Decorators cannot express query-parameter-conditional permissions, so the check lives in require_cancel_permission_when_action(), applied at the top of the handler. Regression drives the real helper through the production middleware: runs:read-only PAT + action is 403, the same token joins action-less, runs:read+cancel passes, session control unaffected. * docs(changelog): add the PAT feature entry * docs(readme): add personal access tokens section Repo documentation-update policy requires user-facing features to update README.md in the same changeset; the PAT feature previously touched only backend/docs/API.md and the gateway AGENTS.md. * fix(auth): require runs:cancel for mutating multitask strategies All five run-creation entrypoints were gated only by runs:create, but RunCreateRequest.multitask_strategy accepts interrupt/rollback and start_run forwards it to create_or_reject, which terminates an already-active run. A runs:create-only PAT could therefore kill an existing run through a create request, bypassing runs:cancel. Decorators cannot express body-parameter-conditional permissions, and per-route checks leave the same hole for the next entrypoint, so the gate lives in start_run itself — the single choke point every run-creation path (HTTP routes and internal launchers) flows through. Regenerate launches pass multitask_strategy="reject" and are unaffected; requests without a stamped auth context (internal/test compositions) skip the gate. The check is the shared authz.require_cancel_permission_if primitive; require_cancel_permission_when_action now delegates to it, so every request dimension that carries cancel capability (query action, body strategy) flows through one gate. Regression drives the real middleware stack: runs:create-only PAT + interrupt/rollback is 403 with the exact detail, reject (explicit and default) stays available, runs:create+cancel passes, session control unaffected; a source anchor pins the gate inside start_run. * fix(runs): keep observer joins from applying creator cancel-on-disconnect sse_consumer's finally block applied the record's on_disconnect=cancel policy on ANY consumer's disconnect. The join surfaces (GET /join and the action-less GET/POST stream join) feed it the existing RunRecord, so anyone with thread read access — including a runs:read-only PAT — could cancel a locally-owned running run simply by closing the SSE connection, without runs:cancel. The policy expresses the creator's intent for their own connection; an observer's disconnect must never be read as that intent. sse_consumer gains apply_on_disconnect (default True). The two join surfaces pass False; the creating endpoints (thread-scoped and stateless create-and-stream) keep the creator semantics unchanged. wait_for_run_completion needs no change: its callers are creator-side or post-explicit-cancel paths only. Regression exercises a real generator close — the same machinery Starlette drives on client disconnect — against the production sse_consumer: creator stream disconnect cancels, observer join disconnect does not; a wiring anchor pins both join call sites and the creator defaults. API.md documents the cancel-capability constraint (this fix plus the action/strategy gates) in PAT Constraints. * test(auth): pin the multitask gate behaviorally; state wait invariant Independent adversarial review of the round-5 fixes found the P1-a regression only mirror-pinned: the source anchor could be satisfied by a comment, and deleting the gate from start_run would not fail the suite. This drives the production start_run directly — a create-only auth context gets 403 with the exact detail for interrupt, and a reject request with no cancel permission at all proceeds past the gate (never a permission 403). Also documents wait_for_run_completion's creator-side invariant (every caller is the creating endpoint or post-explicit-cancel) so a future observer wiring thinks twice before reusing it — the one-caller- away variant of the observer-disconnect P1. * docs(changelog): correct the PAT entry's digest and route-policy description The entry said HMAC digests (the implementation stores SHA-256 digests, as documented in API.md and pinned by the repository tests) and claimed the route policy admits 'implemented stateless endpoints' (it admits the thread/run lifecycle routes, narrowing further by scopes). Also notes the cancel-capability gate now covering action and multitask strategies. * fix(auth): enumerate the PAT runs route policy per implemented subroute The runs subtree rule was a GET|POST /runs(/.*)? wildcard — it pre-authorized every current and future subroute under /runs, including methods the router never implemented (e.g. GET /runs/stream), which is the same latent default-deny weakening the threads collection rule was tightened for: a future route added under /runs would become PAT-reachable without an explicit policy change. The wildcard is replaced with six segment-precise rules covering exactly the 14 implemented method+path combinations; the {run_id} slot necessarily matches any single segment, so the POST-only collection names (stream, wait, regenerate, edit-regenerate) are excluded from the GET run-id rule via negative lookahead — no dead method stays pre-authorized. Behavior for implemented routes is unchanged. test_pat_runs_policy_admits_exactly_the_mounted_routes derives the expected set from the mounted thread_runs router instead of a hand-maintained list: every implemented GET/POST route under /runs must be admitted, routes in this router outside the subtree stay denied, and representative unimplemented neighbors are denied — so adding a route under /runs now fails CI until it is explicitly allowlisted, and a removed route leaves a dead rule visible. API.md's PAT constraints list the enumerated routes and drops a feedback mention that belonged to the stateless /api/runs axis. * docs(migration): add the 0017 renumbering coordination note to 0017 The PR's migration-coordination comment states each migration file carries the note; the file did not. Adds it: numbering was generated against main head 0016 alongside #5078 and #4843; whoever merges first keeps the slot, the others renumber on rebase (revision/down_revision plus the bootstrap head assertions). * fix(auth): pad base62 tokens to a fixed 43-char width int.from_bytes discards leading zero bytes, so the unpadded encoder returned a variable-length body — empty for all-zero input, and shorter than 40 characters for any draw below 62**39 (~1 in 14.5M), leaving test_generate_pat_token_format probabilistically flaky and the token body without stable width (review round 6, P3). _base62 now left-pads with "0" to _base62_width(len(data)) — the exact integer digit count (62^43 > 2^256 > 62^42, so 43 for 32 bytes). The format test asserts the exact fixed width instead of a probabilistic floor, and a new unit test pins the all-zero, leading-zero-byte, and max-value edges deterministically.	2026-08-29 23:50:45 +08:00

Nan Gao	c542185a7f	feat(extensions): add gateway contribution points and packaged extension management (#4780) ... * feat(extensions): add gateway services and routers * feat(extensions): add standalone reference extension * fix(extensions): harden contributed gateway routes * docs(extensions): document gateway contribution points * feat(extensions): add operator CLI for packaged extension management Add `deerflow extensions install/list/enable/disable/remove` plus the root `make extension-*` wrappers, backed by an `ExtensionManager` that owns one transaction over backend/pyproject.toml, backend/uv.lock, the managed source snapshot, the uv environment, and the `plugins:` block in config.yaml. Install accepts a package requirement, a public HTTPS Git URL, or a local directory. Local directories are copied to backend/extensions/sources/ as deployable snapshots rather than editable installs, and the root .dockerignore re-includes that tree so snapshots reach the backend builder. Remote sources are HTTPS-only; SSH Git, file:// and local wheels are rejected because the stock Docker builder cannot reproduce them. Because environment configuration can still resolve a plain package name to a local wheel (a UV_FIND_LINKS wheelhouse, say), every uv add/remove is followed by an audit of the new lock: any local reference the stock image build cannot reproduce rolls back the whole transaction. A config carrying duplicate top-level `plugins:` keys is rejected outright rather than managed against one block while the Gateway reads another. Dependency synchronization now has one lock authority. The `extensions` dependency group joins [tool.uv].default-groups, every startup path syncs the same lock with --locked and launches with --no-sync, and the Docker images move to uv 0.11.1 for the --no-workspace boundary the manager needs. Loader gains `enabled`, `name` and `package` fields so a disabled extension is skipped before resolution and import. Co-authored-by: Codex <codex@openai.com> * fix(extensions): stop the managed plugins rewrite from destroying config Two data-safety defects in the managed `plugins:` block writer. The "next top-level key" boundary was a regex matching only `[A-Za-z_][A-Za-z0-9_-]*` or a quoted key. `AppConfig` is `extra="allow"`, so a config may legally carry any top-level key, and a key the pattern cannot recognize did not fail loudly — it read as "no next section", and the rewrite replaced that neighbour and its entire subtree with the managed block. `my.key`, `2fa`, `$schema`, `my key` and non-ASCII keys were all silently deleted by a plain `extension-enable`/`disable`. Both boundaries now come from the YAML parser's node marks, so key shape is irrelevant. The file-final branch never consulted the trailing-comment scan the has-next-key branch used, so any comment below the block was dropped. Since the manager appends `plugins:` at end of file, that is the steady-state shape for most installs: an operator note below the block was destroyed on the next toggle. Separately, every managed install wrote `required: true` while the loader defaults to false. That turned any later load failure — broken wheel, missing native library, deleted snapshot — into a Gateway startup abort recoverable only with shell access. New records are now written `required: false`, with an explicit `install --required` opt-in; adopting an existing hand-written record still preserves the operator's own choice. * fix(extensions): harden the manager transaction and correct its docs Follow-up hardening on the extension package manager. Security posture, which the docs already claimed: - Scrub `UV_PYTHON`, `UV_INSECURE_HOST`, `UV_CONSTRAINT` and `UV_NO_BUILD_ISOLATION` from the controlled uv environment. `UV_PYTHON` swaps the interpreter that the entry-point probe then imports and calls, and every later `uv run --no-sync` startup uses; `UV_INSECURE_HOST` removes the TLS validation the HTTPS-only source rule depends on. Neither is an index, proxy, cache or credential-provider setting, so neither was covered by the carve-out. - Recognize run-together and all-caps secret query parameters (`accesstoken`, `ACCESSTOKEN`, `key`, `pw`, `sas`, `code`). The camel-case splitter only fires on case transitions, so only the separated spellings were caught. Short generic words stay boundary-anchored, so `?keyword=` remains installable. - Validate the config before running any uv command. `uv add`/`uv sync` execute the package's build backend, so a config the manager could never write to must fail before that code runs rather than afterwards through rollback. Transaction integrity: - Run the second dependency-file restore from a `finally`. The recovery sync runs without `--locked` when the checkout had no lock, so uv writes one while resolving; if that sync then failed, the restore was skipped and the operator kept a lock file they never had. A failing recovery sync now also reports the original failure instead of replacing it. - Skip the recovery sync on cancellation. Answering Ctrl-C with a full dependency resolve invites a second interrupt that escapes the handler and strands the checkout mid-transaction; the declarations are already restored and the next locked startup sync reconciles the environment. - Retry a non-blocking lock on Windows instead of using `msvcrt.LK_LOCK`, which gives up after ~10s — far shorter than a real `uv add` plus `uv sync`, so contention surfaced as `Permission denied` rather than serializing. - Locate the entry-point probe's JSON payload instead of parsing stdout's first line, so a `sitecustomize`/`.pth` banner cannot roll back a good install. - Warn when the lock records a loopback source. `127.0.0.1` inside the image builder is a different machine, but unlike an environment-driven wheelhouse resolution this is a source the operator typed deliberately, so it is reported rather than rolled back. Private-network indexes are untouched: a builder on that network can reach them. Docs: the blanket claim that failed operations restore the config file was wrong — the conflict branches deliberately preserve a concurrent external edit and leave `remove` deactivated. Document that, the `required: false` default, the config preflight, the interrupt behaviour, and where the plugins-block boundaries come from. * test(gateway): pin the request-path projection agreement `get_request_route_path()` imports the private `starlette._utils.get_route_path` so the auth and CSRF predicates classify the exact string Starlette's router matches on. Its requirement is not "strip root_path correctly" but "return what the dispatcher is matching", so delegating to the router's own implementation keeps the two in lockstep by construction. Keep the private import rather than vendoring a copy: an import that disappears fails loudly at startup, while a stale copy diverges silently at a security boundary. Cover the property directly instead of the mechanism, so the tests survive a future reimplementation: - projection edge cases, including the segment-boundary guard that keeps root_path="/api" from slicing "/apifoo/models" into a string the router would never match - agreement with the router under nested mounts - the two bypasses these predicates exist to prevent: a protected route mounted under the "/health" public prefix must still 401, and a POST mounted under "/api/webhooks" must still require a CSRF token Both are verified to fail when the projection is reverted to `request.url.path` (9/13 red) and when a plausible vendored copy omits the boundary guard (the 2 boundary cases red). Declare starlette as a bounded direct dependency so a bump — which is security-relevant here — shows up in review rather than arriving silently through FastAPI. * ci: pin uv to the version production ships ExtensionManager is not a consumer of uv the build tool -- it is a program whose whole job is driving `uv` as a subprocess, depending on its CLI behavior (`--no-workspace`, `--no-sync`, what `uv add` writes into `[dependency-groups] extensions`) and on the `uv.lock` serialization format. uv is closer to a runtime dependency with a contract than to incidental tooling. backend/Dockerfile pins that binary to 0.11.1, but all eight astral-sh/setup-uv steps installed whatever was latest at run time, so CI exercised the manager against a uv that is not the uv production runs. The sharpest failure that allows: a newer uv bumps uv.lock's `revision`, CI stays green because the same uv reads back what it wrote, and the pinned uv in the production image cannot read the committed lock. `uv lock --check` is version-sensitive for the same reason -- it verifies the lock is what *this* uv would produce, and two versions can emit equivalent but non-identical output. Pin every step to 0.11.1 and lift the one lingering setup-uv@v3 to v7 so the steps share input and caching behavior. Pinning alone drifts apart again on the next bump, so add a constraint test in the style of test_compose_default_bind_host.py: the Dockerfile's UV_IMAGE tag is the single source of truth, and both compose defaults plus every setup-uv step must match it. Verified to fail when a pin drifts, when a step omits `version`, and -- the real scenario -- when the Dockerfile is bumped alone, which lights up the workflows and both compose files at once. * fix(gateway): state the extension route auth limit and abort a failed dev sync Two scoped review follow-ups. README: contributed routers cannot enter the host's reserved public prefixes, which makes every extension endpoint session-authenticated -- there is no way to expose an unauthenticated route. The rejection rule was documented but its consequence was not, so inbound provider webhooks and public status endpoints read as merely undocumented rather than out of scope for this release. docker/dev-entrypoint.sh: the self-heal retry reuses `--locked`, so it repairs a corrupt .venv but never a lock that disagrees with pyproject.toml. `set -e` already stopped the script there -- uvicorn was not being started against a stale environment -- but it exited on a bare uv exit code with no indication of what to do. Abort explicitly with the cause and the fix. Tests slice the sync block out of the real script and run it against a stub uv, so they exercise the shipped code rather than a copy of it (/app/backend only exists inside the container). They cover the success path, the retry that recovers, the abort, and the guidance. Verified against the pre-fix script: only the guidance case goes red, confirming the abort itself was already correct. * fix(extensions): point Git SSH shorthand at the HTTPS correction Git's SCP-like shorthand carries no URL scheme, so `git+git@host:org/repo.git` reached the scheme rules looking like a bare path and was rejected with "local path references are not deployable; pass a local directory so DeerFlow can snapshot it". The operator asked for a remote source, so that guidance points at the wrong fix. Detect the shorthand ahead of the scheme rules and report the public-HTTPS correction instead. The bare `git@host:org/repo.git` spelling took a different wrong turn: packaging parses it as a direct reference named `git`, leaving `host:org/repo.git`, whose `host` reads as a URL scheme and produced the generic HTTPS message. Both spellings now share one message, as does the PEP 508 named form. * docs: keep the root extension summary within its new budget #4799 split the depth out of the module guides and added a size gate; the root file's job is now orientation, and this branch had pushed it 192 bytes past the soft limit. The manager transaction, source rules, and lock discipline are already stated in full in the extensions guide, so the root keeps the one-line orientation and points there instead of restating them. --------- Co-authored-by: Codex <codex@openai.com>	2026-08-13 23:55:30 +08:00
Nan Gao	7389331e65	feat(extensions): observe task lifecycle and system model calls (#4684) ... * feat(extensions): observe task lifecycle and system model calls PR 1 (#4636) gave extensions a middleware chain, and a middleware only sees what passes through the agent graph. Two runtime surfaces stay invisible to it: when a lead run or a subagent begins and ends, and the DeerFlow-owned model calls made outside the graph. This slice adds both, with no new Gateway surface -- routers, services, and the reference extension stay in PR 3. Contract (deerflow-extension-api 0.1.1) --------------------------------------- Two contribution kinds join `middlewares` on the registry: `task_lifecycle` (`on_task_start` / `on_task_stop`, receiving a `TaskInfo` and a conservative `TaskOutcome` of completed / aborted / failed) and `system_model_observer` (`on_system_model_call`, receiving a `SystemOperationKind`, a `SystemModelRequest` snapshot, and a `SystemModelResult` carrying either the response or the provider exception plus a duration). `SystemModelRequest.messages` normalizes to a tuple at construction. Goal evaluation and memory extraction pass a message list while title generation and summarization pass one prompt string, and a bare `str` already satisfies `Sequence` -- without normalization an observer iterating `request.messages` would silently walk characters. Copying also makes the frozen snapshot immutable in fact rather than only by declaration, since observations may run after the call site returns and keeps mutating its own list. Registry marks and rollbacks become per-bucket and positional, so an `install()` that fails after registering two different kinds cannot leave one of them behind. `needs_task_store` now covers all three kinds: a deployment that registers only lifecycle hooks still gets a task store. Task lifecycle -------------- The lead worker notifies start after the run has started and stop after completion persistence and the completion hook, but before clearing the finalizing barrier and publishing the stream end -- holding the barrier across stop is what keeps a same-thread replacement run from overlapping this task's lifecycle. Cancellation raised out of the stop notification is deferred, not propagated in place, so a cancelled run still clears the barrier and emits its end frame. A subagent with a parent `run_id` wraps its execution in the same pair inside `finally`, reporting `parent_task_id` so a delegation tree is reconstructable; a subagent without a `run_id` (embedded client, standalone LangGraph Server) logs and skips rather than inventing a parent. Contributors run in registration order inside one shared 3s budget and every failure is logged and failed open. System model calls ------------------ Four kinds cover the model calls the middleware chain cannot see: goal evaluation, memory extraction, title generation, and summarization. Each site reports both terminal paths without changing the provider exception the host observes, short-circuits on `has_system_model_observers`, and passes the live task store when the runtime has one (detached work gets an isolated store). The sync summarization half stays unobserved on purpose -- it and its only host caller are the sync side of an async-only runtime, so notifying there would block a thread on a call site the host never reaches; the reason is recorded at the call site. The DeerMem backend must stay vendorable and cannot import the extension API, so it reports through a new `MemoryCallbacks.on_memory_llm_result` host hook that the DeerFlow-side callbacks translate into an observation. Notification loop ----------------- Extension resources must be touched on the loop that created them, but subagents can execute on isolated loops and DeerMem runs on a worker thread. The Gateway registers its serving loop before any runtime dependency starts and resets it last through the exit stack, so every startup-failure and cancellation path is covered. Awaited hooks raised on another loop are dispatched across with `run_coroutine_threadsafe` and awaited under the same budget; synchronous sites submit fire-and-forget work. Shutdown stops accepting detached observations before the memory flush -- that flush runs on a worker thread and can emit memory observations -- while keeping the loop alive for awaited task hooks until run and subagent drain completes. Tests ----- `test_extension_task_lifecycle.py`, `test_extension_subagent_lifecycle.py`, and `test_extension_system_model_calls.py` cover ordering, fail-open, budget exhaustion, snapshot binding under a concurrent singleton replacement, the loop-dispatch and shutdown-suspension paths, and both terminal paths at every call site. `test_gateway_run_drain_shutdown.py` pins the stop-before-barrier and drain ordering. * fix(extensions): decide notification fail-open by origin, observe cancellation `_notify_each` only guarded `Exception`, so a contributor letting a `CancelledError` escape — an extension implementing an internal timeout with cancellation, say — skipped its successors and reached the worker's deferred-interrupt path, ending an otherwise successful run as cancelled. Fail-open is about where a failure came from, not its base class: only a genuine cancellation of the host task increments `Task.cancelling()`, so propagate on that and contain everything else. `KeyboardInterrupt` / `SystemExit` still propagate. `observe_system_model_call` skipped observers on cancellation for the same base-class reason, leaving goal / title / summarization silent on a terminal path that is routine — interrupt/rollback admission and shutdown both cancel the run task, with the provider tokens already spent. Awaiting observers there is unreliable (a repeated cancel interrupts that await before any of them runs), so report through the same non-blocking submission the synchronous memory bridge uses, then propagate the cancellation untouched. DeerMem keeps `BaseException` around its provider call, now with the reason recorded: that path runs on a worker thread, where cancelling the awaiting side never interrupts the running thread, so `CancelledError` cannot arrive at all. Its host-hook wrapper narrows to `Exception` — only the hook's own failures are non-fatal, and an observability path must not swallow a process teardown signal. * fix(extensions): warn on budget exhaustion, scope observer logs by task, propagate teardown Review response on #4684: - The memory observation bridge caught BaseException, which would swallow a teardown signal raised while dispatching; it now catches Exception, matching the boundary the DeerMem-side call site documents and tests. - A notification-budget timeout raised mid-hook fell into the generic hook-failure path and logged an asyncio-internal traceback; it now logs a warning like the pre-hook budget skip, while a TimeoutError a contributor raises on its own stays classified as a hook failure. - System model observer logs passed the operation kind as the task id, so log lines said "task goal/title/..."; they now carry the task scope id alongside the kind.	2026-08-11 16:33:22 +08:00

Nan Gao	1f792d0f4b	feat(extensions): add middleware plugin foundation (#4636) ... * feat(extensions): add middleware plugin foundation * fix(extensions): stop config resolution from masking extension loading `create_app()` resolved the configured plugin list inside the fail-open guard around `load_extensions()`. CI has no `config.yaml` (gitignored and never generated by the workflow), so `get_app_config()` raised `FileNotFoundError` there and was swallowed as an extension failure -- `load_extensions()` never ran at all, and the four `create_app()` tests in `test_extension_app_loading.py` passed locally but failed on every runner. Resolve the plugin list before the guard. Only an absent `config.yaml` is tolerated, mirroring `_resolve_trace_enabled_for_app_construction()`: `create_app()` runs at import time, and lifespan still performs strict config loading before serving. A `config.yaml` that exists but fails to parse or validate now propagates instead of being reported as an extension failure -- reporting it as the latter silently dropped a `required: true` extension rather than failing the boot. Make the tests config-independent with an autouse `stub_app_config` fixture, following the existing pattern in `test_gateway_lifespan_shutdown.py`, and cover both new branches of the config-resolution boundary. * fix(extensions): bind the run's extension snapshot through subagent delegation The lead-agent path resolves one immutable loaded-extension snapshot per run and binds it through task-store allocation and graph construction, but the subagent path re-read the process-wide singleton at execution time. In production both are the same object, yet a `set_loaded_extensions()` between the lead run's start and a subagent's execution (test teardown, a future hot-reload path) would let one run mix two extension generations — exactly what the documented invariant exists to prevent. The graph-build binding is a ContextVar scoped to synchronous construction, so it has already exited by the time a tool delegates; the snapshot has to travel through runtime context instead. The run worker publishes it under the host-internal `EXTENSION_SNAPSHOT_CONTEXT_KEY` (written after the caller merge, popped when the run has none, so a caller-supplied value is never authoritative), `task_tool` reads it back through the type-checking `resolve_run_extensions()`, and `SubagentExecutor` binds it at construction. Callers outside the Gateway run path — embedded `DeerFlowClient`, standalone LangGraph Server — install no snapshot and keep the existing `get_loaded_extensions()` fallback. * refactor(extensions): defer the ordering table by call, not by a lying tuple `CORE_ORDERING_CONSTRAINTS` was a `tuple` subclass that overrode only `__iter__` and resolved into a class-level `_resolved` side channel. A tuple cannot populate its own storage after construction, so the instance stayed the empty tuple it was built as: `len()` was 0, `bool()` was False, `in` was always False, indexing raised, slicing and `reversed()` came back empty, and it compared unequal to the plain tuples tests substitute for it — all while iteration yielded the real constraints. Only `assert_ordering` consumed it, and only by iterating, so the split went unnoticed. The sibling `_AnchorTable(dict)` uses the same idea soundly because dict is mutable: `self.update()` fills the real storage, making every inherited operation correct. That trick does not survive the port to an immutable type. Replace it with `core_ordering_constraints()`, matching how `stack.py` defers the same kind of table via `_anchors()`. The deferral is kept — it is about dependency direction, not just cycles: `extensions/` is the layer the middleware layer calls into, so a module-scope `agents.middlewares` import here points the dependency backwards and closes a cycle as soon as any middleware imports something under `extensions/` at module level. Resolution stays at `assert_ordering` time, which already runs inside the middleware builder. Tests pin both halves: the returned value is a plain tuple whose len/bool/ membership/indexing/reversal/equality agree with iteration, and a subprocess probe asserts importing `extensions.ordering` does not load the middleware layer while calling the function does.	2026-08-04 22:33:26 +08:00

Introduces an AgentStore interface routing all read/write surfaces, an agents table + migration 0006, startup validation, and a file->db importer. Follows the thread_meta store / run_events backend-switch / 0003_scheduled_tasks migration patterns; no new dependency. * fix(agents): make db storage path production-ready (review round 1) Addresses review feedback on the db/sync agent-storage path: - sql.py: mirror the async engine's per-connection SQLite PRAGMAs on the sync engine (busy_timeout=30000, synchronous=NORMAL, foreign_keys=ON, WAL) so both engines behave identically against the shared DB; guard the engine cache with a lock (double-checked) so concurrent first-touch cannot build duplicate engines or register the connect listener twice. - routers/agents.py + routers/assistants_compat.py: offload the sync-store reads that ran on the event loop (list/get/check, update's pre-read + legacy guard + refresh, and assistants_compat's four list routes) via asyncio.to_thread — on db+postgres each was a network round trip stalling the loop. Writes were already offloaded. - file.py: translate the create() mkdir(exist_ok=False) race FileExistsError into AgentExistsError (router 409, matching SqlAgentStore's IntegrityError path); correct the _write docstring — per-file atomic replace, two commits sequential not transactional. Tests: sync-engine PRAGMA + engine-cache reuse assertions; file create-race -> AgentExistsError; strict Blockbuster anchor over the read endpoints so a regression back onto the loop fails CI. * fix(agents): address round-2 review on the db store path - update_agent tool: align the docstring/inline comment with FileAgentStore._write. Cross-field write atomicity is db-only; the file backend commits config then soul via two sequential os.replace (a crash between them can leave a fresh config.yaml beside a stale SOUL.md). The dropped partial-write *reporting* is an intentional tradeoff — the stage-then-replace safety is preserved (test_update_agent_soul_failure_does_not_replace_config still holds). - SqlAgentStore.update(): true upsert. Catch IntegrityError on the insert-on-missing branch, re-fetch and apply, so two concurrent first-time writes (e.g. two setup_agent handshakes) converge instead of surfacing a raw UNIQUE(user_id, name) violation as a 500. Symmetric with create(). - get_agent_store(): document the graph-subprocess config-resolution invariant (the except->file fallback is a genuine no-config path, not a mask for a misconfigured graph process) and pin it with two tests driving the real get_app_config() file resolution: db resolves from an on-disk config.yaml, file fallback when config is unresolvable. * test(agents): cover SqlAgentStore.update() write-race upsert recovery Mandatory-TDD test for the round-2 fix in 0680340a: two concurrent first-time update()s where the loser's insert hits UNIQUE(user_id, name). Deterministically forces the IntegrityError recovery path by making the first _row probe miss the committed winner, and asserts last-writer-wins instead of a surfaced 500.	2026-07-23 08:03:21 +08:00
Vanzeren	42baed8c8c	feat(checkpoint): dual-mode checkpoint storage with LangGraph DeltaChannel (#4292) ... * feat(checkpoint): dual-mode checkpoint storage with LangGraph DeltaChannel Add a restart-required database.checkpoint_channel_mode ("full" default, "delta") that stores the messages channel via LangGraph 1.2 DeltaChannel, cutting checkpoint storage from O(n^2) to O(n) for append-only history. Existing full checkpoints seed delta state transparently; no data migration. - config: mode schema + freeze-on-first-use with CheckpointModeReconfigurationError; mode marker persisted in checkpoint metadata; unsafe delta->full downgrade rejected fail-closed with CheckpointModeMismatchError (run-level error, failed state read) - state: delta message state schema; CheckpointStateAccessor centralizes materialized reads for all consumers (threads API, branches, regeneration, compaction, state updates, memory, goal workers) - runtime: raw writers (run durations, interrupted title, thread goal) parent their checkpoints to the checkpoint they derive from, preserving delta ancestry; rollback forks the pre-run lineage through a state mutation graph with Overwrite restores; InMemorySaver delta-history override delegates to the base walk (fixes dropped first write after migration, also present upstream) - tests: conformance suite over {memory, sqlite, postgres} covering migration replay, stable message IDs, storage shape and writer preservation; conftest fixture isolates the frozen mode between tests; stale config fakes refreshed - ci: backend unit tests gain a postgres service * fix(checkpoint): close materialization gaps in goal flow, guard public factory - Route goal-continuation message reads through CheckpointStateAccessor: raw channel_values reads see the delta sentinel in delta mode, which disabled goal continuation (stand_down=no_durable_end_of_turn) after durable assistant turns. Raw tuples remain for tuple-only metadata (checkpoint id, pending_writes). - Reject checkpoint_channel_mode='delta' + checkpointer in create_deerflow_agent at construction: factory-built persisted graphs bypass mode-marker injection and the fail-closed gate, reproducing silent mixed-mode state loss. Delta without persistence stays allowed. - Import the postgres saver lazily (pytest.importorskip in the fixture) so the documented default install collects the suite; add a CI job running pytest --collect-only on uv sync --group dev without extras. - Fix test_checkpointer fallback test to patch get_app_config at its use site (provider module), making it deterministic when a local config.yaml selects a persistent backend. * fix(gateway): preserve extension-owned channels in state mutations, bump config version - build_state_mutation_graph / build_checkpoint_state_mutation_accessor accept an explicit state_schema; branch and POST /state now compile the mutation graph from the thread's effective schema (graph_state_schema on the assistant graph). The base-ThreadState fallback silently discarded channels contributed by custom AgentMiddleware.state_schema on branch (data loss) and returned a false-success 200 on POST /state. - POST /state validates values keys against the mutation graph's channels and rejects unknown fields with 422 instead of ignoring them; reducer detection covers extension channels (BinaryOperatorAggregate or DeltaChannel) so Overwrite replace semantics work for middleware reducers in both modes. - Endpoint regression: custom AgentMiddleware.state_schema value survives branch, updates through POST /state, and an unknown field receives 422. - config_version 26 -> 27 for the new database.checkpoint_channel_mode (example, Helm chart values + README, support-bundle fixture), so existing installs get the outdated-config warning and make config-upgrade merges the field; covered by a test driving the real example file and the real config-upgrade script. * fix(gateway): resolve assistant schema via one boundary, copy branch reducer values with Overwrite GET /threads/{id}/state now resolves the thread's assistant_id through a single reusable boundary (thread metadata -> assistant_id -> effective graph), so channels contributed by a custom AgentMiddleware.state_schema are materialized instead of dropped by the default lead schema. POST /state uses the same boundary instead of resolving the schema ad hoc. Branch writes wrap every copied reducer channel in Overwrite (derived from the effective mutation graph: BinaryOperatorAggregate + DeltaChannel), not just messages, so already-aggregated values are never re-merged. Regression tests use a real AgentMiddleware.state_schema with a non-identity reducer in both full and delta modes: GET /state returns the extension value, POST /state replaces it, branch preserves it byte-for-byte; the unknown-field 422 is a separate assertion. * refactor(checkpoint): collapse read-path round-trips and ship dual-mode parity tests Address review round 4 on PR #4292: - Push ahistory/history limit through Pregel into checkpointer.alist (SQL LIMIT) instead of materializing all rows and breaking in Python - Fold the read-side mode-compat gate onto the returned snapshot's metadata; only writes keep the pre-write tuple fetch (fail-closed) - Cache factory-built accessor graphs per (assistant_id, mode) with factory-identity revalidation; state reads no longer build a lead agent per request - get_thread: one snapshot fetch + one raw pending_writes fetch on the resolved checkpoint (post-checkpoint __error__ writes never surface in snapshot.tasks; verified empirically) - DeerFlowClient.get_thread: single checkpointer.list walk collects pending_writes per checkpoint instead of N get_tuple calls - InMemorySaver delta-history patch: stand-down when the upstream override disappears, try/except guard, validated-version warning, guard tests - make_lead_agent mode precedence: first freeze is owned by app_config (client-supplied configurable key ignored); once frozen, injected key/app_config must match or fail closed - Rollback: lock in non-message channel restoration via fork inheritance with a dedicated reducer-channel test - Add tests/test_threads_checkpoint_mode.py and tests/test_gateway_checkpoint_mode.py referenced by AGENTS.md and the PR validation section: lifecycle parity (memory + sqlite), per-step blob-count storage guard, gateway endpoint parity Counted-saver tests pin checkpoint round-trips for aget/ahistory so these regressions cannot silently return. * fix(checkpoint): precise mode-mismatch HTTP mapping, gate E2E, and accessor resilience - threads router: map CheckpointModeMismatchError to 409 (with cause and thread id) and CheckpointModeReconfigurationError to 503 across all state endpoints instead of swallowing both into a generic 500 - gate coverage: seed a real delta checkpoint into AsyncSqliteSaver and assert aget/aupdate/ahistory fail closed; assert 409 at the HTTP boundary through the real route stack - rollback: compile the restore mutation graph with the thread's effective state schema per the build_state_mutation_graph contract - inheritance contract locks: rollback and manual compaction preserve middleware-contributed channels via checkpoint fork cloning - services: revalidate the accessor-graph cache against app_config identity so config.yaml hot-reloads never serve a stale compiled graph - services: degrade full-mode state reads to raw checkpointer reads when the agent factory is unavailable (delta gate still applies; delta mode has no fallback) - deps: override websockets==16.0 (langgraph-sdk 0.4.2's <16 pin silently downgraded 16.0 -> 15.0.1; pin is not grounded in any API incompatibility) and bump the langchain lower bound to what the lockfile actually resolves * fix(checkpoint): include anchor checkpoint in degraded history walk + cover get_thread - _RawCheckpointReadAccessor.ahistory: alist(before=...) is exclusive while pregel's get_state_history treats config.checkpoint_id as the inclusive start; fetch the anchor explicitly so both read paths paginate identically - extend the degraded-path gateway test: GET /thread returns raw values, and POST /history with before starts at the anchor checkpoint * fix(gateway): preserve degraded checkpoint timestamps * fix(gateway): harden degraded checkpoint access * fix(gateway): resolve assistants for checkpoint reads --------- Co-authored-by: Willem Jiang <willem.jiang@gmail.com>	2026-07-22 08:33:29 +08:00

Adds regression tests for the request guard, session teardown on delete, and the composing-Enter key decision. * fix(frontend): smooth streaming in long tool threads * Revert "fix(frontend): smooth streaming in long tool threads" This reverts commit f0462516eabe77f138d4027ea1c714fb226683cf. * fix(browser): address review security and lifecycle findings - Reject cross-origin WebSocket upgrades on the live browser stream (Origin allow-list reuse of CORS/same-origin helpers) to close a WS-CSRF hole, and fail closed when the ownership store is absent. - Warn when a CDP-attached session runs with the SSRF request guard off, and drop the unreachable CDP screencast teardown dead code. - Read browser session launch config from a single canonical source (browser_navigate) so it is deterministic regardless of call order. - Bound per-thread Chromium accumulation with idle-timeout eviction and an LRU max-sessions cap. - Reset the Live reconnect counter on a successful open so the stream can't permanently stall after the cumulative attempt cap. * fix(frontend): reduce long tool thread render stalls Reuse stable historical message groups during streaming, defer heavy Markdown and browser previews, and lazy-decode message images. * fix(browser): keep live control responsive during continuous input Why: Manual browser control felt laggy — a physical click ran the remote Playwright click three times and each non-move input synchronously awaited a JPEG screenshot, so events queued behind capture (queue wait up to ~237ms). The first async attempt used a trailing-edge debounce, which froze the visible page until a wheel/keyboard gesture stopped ("scroll finishes, then it jumps"). What: - Frontend forwards one `click` per physical click instead of also emitting `down`/`up`, so the remote page is not clicked twice per gesture. - Backend detaches live-frame capture from input dispatch: non-move actions start a rate-limited background refresh loop (leading frame + bounded cadence) that keeps emitting frames while input continues and never blocks dispatch. - Add regression tests: input dispatch no longer awaits the screenshot, rapid inputs coalesce, and continuous input keeps refreshing before it stops. Scenarios: Verified in the live Browser panel — a single click completes in ~57ms (was blocked behind a 171ms capture), and a 1.14s sustained wheel gesture renders ~7 frames throughout the scroll instead of one frame after it ends. * fix(browser): harden worker and session lifecycle * fix(browser): address latest review feedback * fix(frontend): preserve optimistic new-chat message * test(e2e): preserve mocked message run ids * fix(browser): address capability review feedback --------- Co-authored-by: Willem Jiang <willem.jiang@gmail.com>	2026-07-21 11:46:33 +08:00
heart-scalpel	3bc3af2530	fix(runs): close multi-worker ownership gaps in run atomicity (#3948) (#4003) ... * feat(runs): cross-process run ownership with lease + reconciliation (#3948) Implements work items 2 and 3 of the multi-worker P0 plan (docs/multi_worker.md). Work item 1 (Postgres startup gate, #3960) already landed; this PR makes run creation race-safe across worker processes and lets Postgres deployments recover orphaned inflight runs from crashed workers without mis-marking live runs as orphans. Work item 2 — cross-process atomic create_or_reject - Alembic revision 0004_run_ownership adds runs.owner_worker_id, runs.lease_expires_at, idx_runs_lease, and a partial unique index uq_runs_thread_active (one pending/running run per thread). The index is declared on RunRow.__table_args__ with sqlite_where + postgresql_where (mirroring uq_channel_connection_active_identity) so the empty-DB bootstrap path — which runs Base.metadata.create_all + alembic stamp head without executing any revision's upgrade() — also lands it on fresh deployments. Migration 0004 additionally creates it idempotently for legacy/versioned upgrades. - RunRepository.create_run_atomic is the new atomic primitive: - reject: INSERT directly; the partial unique index catches duplicate active runs; the manager surfaces the result as ConflictError. - interrupt/rollback: SELECT FOR UPDATE the conflicting rows, skip rows whose lease is still valid AND owned by another live worker (raise ConflictError — the INSERT would have failed on the index anyway, and a retry loop cannot make progress), cancel the rest in the same transaction, then INSERT the new row. Rows owned by this worker are interruptible regardless of lease state. - RunManager.create_or_reject dispatches to the store under the existing local lock; same-worker in-memory cancellation runs after the store commit succeeds. MemoryRunStore mirrors the same semantics for tests and database.backend=memory. Work item 3 — lease heartbeat + Postgres reconciliation - RunOwnershipConfig (lease_seconds=30, grace_seconds=10, heartbeat_enabled=false by default), registered as startup-only in reload_boundary.STARTUP_ONLY_FIELDS because the heartbeat background task is created once in langgraph_runtime() and is not rebuilt on config.yaml edits. - When heartbeat_enabled, each worker renewes leases on its own active runs with interval = lease_seconds / 3. The loop is bounded and stop-event-cancellable so shutdown is prompt. - reconcile_orphaned_inflight_runs now runs on every backend — the sqlite-only gate in app/gateway/deps.py is dropped in the same commit so there is no window where Postgres would mis-mark live Worker A runs as orphans. Reconciliation errors only runs whose lease is NULL (legacy pre-ownership rows) or older than grace_seconds. In single-worker mode (heartbeat off, NULL leases) all inflight rows reclaim immediately, preserving the pre-ownership recovery latency. - Heartbeat starts AFTER startup reconciliation and stops BEFORE the in-flight run drain on shutdown so the two cannot race. GATEWAY_WORKERS=1 with heartbeat_enabled=false keeps current behavior. Verified: 170 related tests + full backend suite (minus Docker-gated live tests) green; ruff check + ruff format clean. * fix(runs): tighten unique-violation handling and document clock-sync budget Three follow-up fixes to the cross-process run ownership work in #3948, surfacing during review. 1. _is_unique_violation: detect by driver-native signal, not message text The previous substring heuristic ("unique" + "violat", or "duplicate") missed SQLite's actual phrasing "UNIQUE constraint failed: <table>.<index>" — SQLite says "failed", not "violates", and never "duplicate". On SQLite the detector returned False, the reject path re-raised the raw IntegrityError, and clients saw HTTP 500 instead of ConflictError 409. The conversion is the load-bearing piece of the "store is source of truth" design but was untested — every atomic test used MemoryRunStore, which raises ConflictError directly and never reached this branch. Now prefers driver-native signals: psycopg pgcode/sqlcode "23505" and sqlite3 sqlite_errorcode SQLITE_CONSTRAINT_UNIQUE (reachable through SQLAlchemy IntegrityError.orig). Message matching stays as a fallback with SQLite's exact "unique constraint failed" phrase added. 2. interrupt/rollback: convert exhausted-retry IntegrityError to ConflictError The reject branch converts unique violations to ConflictError. The interrupt/rollback retry loop did not — on the 3rd attempt it re-raised the raw IntegrityError, leaking HTTP 500 for the same race condition that reject surfaces as 409. Symmetric conversion added after the loop; callers now see a consistent ConflictError regardless of strategy. 3. Document clock-sync requirement for multi-worker lease reconciliation reconcile_orphaned_inflight_runs compares another worker's UTC lease_expires_at against this worker's datetime.now(UTC). The only skew budget is grace_seconds (default 10s) — worst case, with the owning worker's heartbeat just about to fire, a peer whose clock is more than ~grace_seconds ahead can mis-reclaim a still-live run as an orphan. Documented in RunOwnershipConfig's docstring (with the math) and in config.example.yaml (with operational guidance), so operators in NTP-poor environments know to raise grace_seconds. Default unchanged: 10s is reasonable for NTP-synced K8s/cloud, and bumping it would slow recovery of genuinely dead workers (lease_seconds + grace_seconds from last heartbeat to reclaim). Tests: - test_create_run_atomic_reject_propagates_conflict_on_unique_violation: end-to-end against a real SQLite-backed RunRepository, pre-inserts an active run, asserts reject-strategy create surfaces as ConflictError rather than raw IntegrityError. - test_is_unique_violation_detects_real_sqlite_integrity_error: unit test for the detector against a real SQLite-raised IntegrityError; asserts driver-level sqlite_errorcode is SQLITE_CONSTRAINT_UNIQUE. - test_interrupt_exhausted_retries_surface_as_conflict_error: pins the symmetric 409 behavior after the retry loop exhausts. Verified: ruff check + ruff format clean; multi-worker + run_repository + owner_isolation + reload_boundary suites green. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * fix(runs): close multi-worker ownership gaps in lease heartbeat and unique-violation detection Five code-review fixes from docs/multi_worker.md: 1. Drop unused ``claim_inflight_runs`` primitive — no caller anywhere. ``create_run_atomic`` does its own inline claim (SELECT FOR UPDATE + cancel) inside the INSERT transaction; a separate claim primitive would split that into two transactions and open a claim→INSERT race. Removes ~40 lines across base.py / memory.py / sql.py plus the unused ``now_iso`` parameter, freeing future RunStore implementations from providing it. 2. Broaden ``_renew_leases`` filter to renew pending/running runs owned by this worker even when ``record.task is None``. The previous ``task is not None`` requirement skipped the brief window between ``create_run_atomic`` inserting the row and the worker spawning the agent task; under event-loop load that window can approach ``lease_seconds``, after which peer reconciliation marks the run ``error`` (visible) or a peer's ``create_or_reject("interrupt")`` silently kills the queued run. Filter now: ``task is None or not task.done()``. 3. Document the unsynchronised ``record.lease_expires_at = new_expiry`` write. ``lease_expires_at`` is the only field on an existing record this path mutates; ``set_status`` / ``_persist_status`` touch other fields, so there is no concurrent writer to race against. Re-acquiring ``self._lock`` would serialise unrelated run mutations for no gain. 4. Gate ``_is_unique_violation`` message fallbacks on ``isinstance(current, (SAIntegrityError, sqlite3.IntegrityError))``. The driver-code path (pgcode/sqlite_errorcode) remains load-bearing; substring fallbacks are now belt-and-suspenders only for cases where the driver attribute isn't reachable through the cause chain. Without the gate, any application exception whose ``str()`` happens to contain "duplicate key" / "unique" + "violat" (CHECK constraint, validation error) would silently surface as HTTP 409 instead of 500. 5. Route ``update_lease`` through ``_call_store_with_retry`` for consistency with every other store call, and wrap ``await self._renew_leases()`` in ``_heartbeat_loop`` with ``except Exception: logger.warning(...)``. Previously a transient error from the snapshot path or an unexpected exception would kill the heartbeat task silently — after which no lease is ever renewed again and every active run eventually looks orphaned. ``except Exception`` lets ``CancelledError`` (BaseException since 3.8) propagate so shutdown cancellation still works. Regression tests: - ``test_heartbeat_renews_pending_run_before_task_is_spawned`` - ``test_is_unique_violation_does_not_misclassify_application_exception`` Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * fix(runs): harden multi-worker migration, memory atomicity, and tz-naive lease comparison Three follow-up fixes to the multi-worker run ownership work: - migration 0004 dedupe pass: cancel superseded duplicate active rows per thread before creating the partial UNIQUE index ``uq_runs_thread_active`` so dirty DBs (Postgres deployments that had reconciliation skipped by the old sqlite-only gate, or any env that ran GATEWAY_WORKERS>1 before this PR) do not abort the alembic upgrade and block gateway startup. Keeps the newest active row per thread, marks the rest as error with an explanatory message. - MemoryRunStore.create_run_atomic interrupt/rollback path: split the single- pass loop into two passes (collect candidates, validate, then mutate) so a ConflictError raised on a later candidate does not leave earlier candidates half-interrupted. Mirrors the SQL store's transactional rollback semantics; the entire test_multi_worker_run_ownership.py suite runs against memory so this divergence was giving false confidence. - RunRepository.create_run_atomic interrupt path: coerce tz-naive ``row.lease_expires_at`` to UTC before comparing against the aware ``cutoff``. SQLite drops tzinfo on read despite ``DateTime(timezone=True)`` (this file's own comment acknowledges it), so the Python-side comparison raised ``TypeError: can't compare offset-naive and offset-aware datetimes`` whenever heartbeat was enabled on SQLite and a lease was non-NULL. Defaults (heartbeat off -> leases always NULL) masked it, but there was no guard against the combination. Follows the existing "naive is UTC" convention from ``coerce_iso``. Each fix ships with a regression test pinning the behavior. Co-Authored-By: heart-scalpel <heart-scalpel@users.noreply.github.com> Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * fix(runs): enforce heartbeat for multi-worker, fix memory-store datetime comparison, lazy-import ConflictError in store layer Three fixes from code review: 1. Extend the startup gate (GATEWAY_WORKERS>1) to also require run_ownership.heartbeat_enabled=true. Without heartbeat every run has a NULL lease, so reconciliation treats all inflight rows as orphans and Worker B would kill Worker A's live runs on every rolling update or scale-up. 2. Fix MemoryRunStore.list_inflight_with_expired_lease to parse created_at as datetime instead of ISO string lexical comparison, and handle tz-naive lease values uniformly with the SQL store. 3. Store layer (sql.py, memory.py) now lazy-imports ConflictError inside create_run_atomic instead of importing from the higher RunManager layer at module level. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * fix(runs): add owner check to update_lease, document create() assumption, restore deleted comment - update_lease (SQL + memory) now requires owner_worker_id match in WHERE clause so the primitive is safe by construction against misuse - create() docstring notes it bypasses atomic create_run_atomic and assumes no active run exists for the thread - restore explanatory comment in MemoryRunStore.aggregate_tokens_by_thread that was dropped in an earlier commit Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * fix(runs): add psycopg3 sqlstate detection and periodic orphan reconciliation - _is_unique_violation now checks sqlstate attribute (psycopg3 uses this instead of pgcode). On Postgres, the only supported multi-worker backend, detection was falling through to the message-substring fallback. - _heartbeat_loop now runs reconcile_orphaned_inflight_runs every 3rd cycle (every lease_seconds) to catch orphans whose lease expires between pod restarts. Single-worker deployments are unaffected (heartbeat off).

heart-scalpel	8cde7f258e	feat(gateway): refuse multi-worker startup on non-Postgres backends (#3960) ... Why: issue #3948 identifies four correctness breakers when GATEWAY_WORKERS > 1. Work item 1 adds a startup gate that refuses to boot when database.backend is not postgres, giving operators a clear error instead of silent SQLite write-lock corruption. The gate runs inside langgraph_runtime() before init_engine_from_config, so a misconfigured deploy never opens a listener or writes to disk. Non-integer env values fall back to 1 so uvicorn's own validation is unaffected.	2026-07-06 15:20:27 +08:00

Reuses one ScheduledTaskScheduleInput for create and edit; backend contract unchanged; zero new deps (pure Intl + DST-safe offset helpers). * feat(scheduled-tasks): full-page i18n + recipe templates + E2E locale pin Localize the rest of the scheduled-tasks page (filters, detail pane, actions, edit form, run list, enum values) via t.scheduledTasks.* in en/zh. Add four built-in recipe templates (GitHub Trending, news digest, issue triage, weekly report) exposed as a chip row that pre-fills title + prompt + schedule. Pin Playwright locale to en-US so E2E selectors stay stable against i18n. No backend change, no new deps. * fix(scheduled-tasks): idempotent 0003 migration, update head constants, future-date once test Merge with main surfaced three CI failures: - 0003_scheduled_tasks create_table collided with legacy test seeds that build from full metadata; guard with inspector.has_table so the revision no-ops when the table already exists (0004/0005 are already idempotent via _helpers.py). - persistence bootstrap concurrency/regression tests pinned HEAD to main's 0002_runs_token_usage; bump to the new head 0005_scheduled_task_thread_nullable. - once-task router test used a fixed past run_at and tripped the must-be-in-the-future validation; use a future date. * address review: ok-check, 502 for trigger failure, mock fields, migration filename, doc fences - fetchThreadScheduledTasks now checks response.ok like the other fetchers. - trigger endpoint returns 502 (not 409) when dispatch fails outright, so clients can distinguish a real conflict from a server-side failure. - E2E mock normalizes scheduled-task objects with context_mode/last_thread_id and nullable thread_id, matching the backend contract the UI renders against. - Rename 0002_scheduled_tasks.py -> 0003_scheduled_tasks.py to match its revision id (file was renamed in spirit already; filename now follows). - CONFIGURATION.md: close the Tool Groups yaml fence and drop the stray fence after the Scheduler notes so the sections render correctly. * fix(scheduled-tasks): harden lease, poller, config, and frontend UX after review * fix(scheduled-tasks): harden run lifecycle, overlap skip, non_interactive gating, and DST conversion after review - defer a once task's terminal status to the run-completion hook; the task stays running until the real outcome, and a startup sweep cancels once tasks orphaned by a crash (launch-time 'completed' could stick forever) - record interrupted runs as a distinct 'interrupted' run status with a readable message; an interrupted once task ends 'cancelled', not 'failed' - enforce overlap_policy=skip for fresh_thread_per_run via an active-run pre-check (same-thread ConflictError can never fire across fresh threads) - protect terminal run statuses from the late launch-path 'running' write - honor context.non_interactive only for internally-authenticated callers; arbitrary clients can no longer strip ask_clarification - fix DST-stale timezone offset in zonedLocalToUtcIso by re-deriving the offset at the resolved instant (once tasks fired an hour late around spring-forward and the create->edit round-trip diverged) - drop dead ScheduledTaskRunRepository.update_by_run_id; share one Gateway API error helper between channels and scheduled-tasks frontends * fix(scheduled-tasks): close review round-3 gaps in guards, concurrency, and API ergonomics - scrub internal-only context keys (non_interactive) from the assembled run config for non-internal callers: gating body.context alone left the same key smuggle-able through the free-form body.config copied verbatim by build_run_config - guard update_after_launch with protect_terminal so the launch bookkeeping write cannot clobber a once task already finalized by a fast-failing run's completion hook (parent-row sibling of the run-row guard) - reject a manual trigger while the task has an active run (409) instead of launching a duplicate concurrent run on fresh_thread_per_run - re-arm a terminal once task to enabled when PATCH pushes run_at into the future; previously the endpoint returned 200 with a next_run_at that could never be claimed - make max_concurrent_runs a real global cap: each poll claims only into the remaining budget of active (queued/running) scheduled runs - paginate GET /scheduled-tasks/{id}/runs (limit<=200, offset) and push the thread filter of /threads/{id}/scheduled-tasks into SQL - stamp context.user_id on scheduler-launched runs, matching IM channels, so user-scoped guardrail providers see the owning user --------- Co-authored-by: Willem Jiang <willem.jiang@gmail.com>	2026-07-04 21:51:57 +08:00

Xinmin Zeng	befe334f10	fix(config): make the reload boundary discoverable from code (#3144) (#3153) ... * fix(config): make the reload boundary discoverable from code, not just docs Closes #3144. The hot-reload contract — per-run fields are resolved through `get_app_config()` on every request, infrastructure fields snapshot at gateway startup — landed in `backend/CLAUDE.md` as part of #3131. A maintainer reading `get_config()` or an `AppConfig` field still had to context-switch to that document to know which fields require a process restart, and there was no enforcement that the prose list stayed in sync with the code. This commit moves the boundary to a machine-readable single source of truth and surfaces it where the code lives: - New `deerflow.config.reload_boundary` module owns the registry of restart-required fields (`STARTUP_ONLY_FIELDS`) and a tiny helper API (`is_startup_only_field`, `iter_startup_only_field_paths`, `format_field_description`). The standardised `"startup-only:"` prefix is exported as `STARTUP_ONLY_PREFIX` so future scanners / lint hooks / doc generators can pivot off it without re-parsing prose. - `AppConfig`'s `database`, `checkpointer`, `run_events`, `stream_bridge`, `sandbox`, and `log_level` fields now build their `Field(description=...)` from `format_field_description(...)`. The same text shows up in IDE hover (Pydantic v2 exposes `description` via `model_fields[...]`). - `channels` is restart-required too but lives outside the AppConfig Pydantic schema (the config section is consumed directly by `start_channel_service`). The registry owns it so the boundary is not split between two places. - `get_config()` docstring points to the registry instead of leaving the reader to find `CLAUDE.md`. The `CLAUDE.md` table collapses to a one-liner pointing back at `reload_boundary.py` so the boundary has one canonical location, not two. Drift coverage in `tests/test_reload_boundary.py`: - Every registered field has a non-trivial reason. - Iterator / membership helpers stay in sync with the dict. - Every registry entry that maps to an `AppConfig` field also carries the `"startup-only:"` prefix in the schema (catches "forgot to update the schema"). - Reverse drift: any AppConfig field whose description starts with the prefix must be registered (catches "marked restart-required in the schema but forgot the registry"). - The runtime introspection that IDE hover depends on (`AppConfig.model_fields["database"].description`) is pinned, so a future Pydantic upgrade or schema swap that breaks the hover surface shows up as a test failure rather than a silent regression. Refs: bytedance/deer-flow#3138 (split summary), #3107 (origin), #3131 (prior boundary fix in prose form). * fix(config): preserve field doc and correct log_level reload reason Two follow-ups on the PR #3153 review: 1. The `log_level` STARTUP_ONLY_FIELDS reason previously claimed `apply_logging_level()` mutates the root logger level. It does not: only the `deerflow` / `app` logger levels are set, and root handler thresholds are conditionally lowered so messages from those loggers can propagate. Reword to match the actual behavior so operators reading IDE hover get accurate restart guidance. 2. `format_field_description(field_path)` was the sole `Field(description=)` for every restart-required field, which silently overwrote the original human-facing documentation — most visibly the `log_level` field that used to list debug/info/warning/error and clarify that third-party libraries are not affected. Extend the helper with a keyword-only `field_doc` parameter that composes the startup-only marker with the original prose so IDE hover documents both *why* the field is restart-required and *what* it actually accepts. Updated all six restart-required AppConfig fields (`log_level`, `database`, `sandbox`, `run_events`, `checkpointer`, `stream_bridge`) to pass their original descriptions through the helper. Tests: two new cases in `test_reload_boundary.py` pin (a) the helper composition and (b) every AppConfig restart-required field still surfaces a recognisable substring of its original documentation. --------- Co-authored-by: Willem Jiang <willem.jiang@gmail.com>	2026-06-07 21:27:14 +08:00
Xinmin Zeng	268fdd6968	fix(gateway): drain in-flight runs before closing checkpointer on shutdown (#3381) ... * fix(gateway): drain in-flight runs before closing checkpointer on shutdown Chat runs execute in fire-and-forget background asyncio tasks that write checkpoints through a shared checkpointer. On shutdown, langgraph_runtime's AsyncExitStack tore down the checkpointer's postgres connection pool while those run tasks were still mid-graph. langgraph's AsyncPregelLoop._checkpointer_put_after_previous then ran its `finally: await checkpointer.aput(...)` against the closed pool, raising psycopg_pool.PoolClosed. Because that put runs in a langgraph-internal task (not on run_agent's call stack), run_agent's try/except cannot catch it and it surfaces as "unhandled exception during asyncio.run() shutdown". Add RunManager.shutdown() to cancel and bounded-await all in-flight runs, and call it from langgraph_runtime BEFORE the AsyncExitStack closes the checkpointer, so the final checkpoint write lands while the pool is still open. The drain is bounded by a timeout so a stuck run cannot hang worker shutdown, and is shielded so a second shutdown signal cannot abandon it mid-drain and reopen the race. Closes #3373 * fix(gateway): address review — preserve completed-run status, bound drain persistence Addresses Copilot review on #3381: - RunManager.shutdown(): decide run status AFTER the drain. Under the lock it now only requests cancellation; after asyncio.wait it marks/persists `interrupted` only for runs still pending or ended cancelled. A run that completes (e.g. `success`) during the drain window keeps its real terminal status instead of being unconditionally overwritten. - Bound the trailing status persistence within the timeout budget (deadline = loop.time()+timeout; gather wrapped in asyncio.wait_for) so a slow store backing off under DB pressure cannot push shutdown past the deadline. - deps: use asyncio.create_task instead of asyncio.ensure_future. - tests: wait deterministically for the run to be in-flight (poll the first checkpoint) instead of a fixed sleep; init shutdown_calls explicitly in the recovery test double; add regression test asserting a run completing during the drain keeps its status (in memory and in the store). * fix(gateway): address maintainer review — surface failed drain persists, clarify timeout constant Addresses @WillemJiang review on #3381: - shutdown(): inspect the gather result of the trailing interrupted-status persistence. _persist_status is best-effort (it catches + logs its own failure with exc_info and returns False, so it never raises out of the gather), but the aggregate result was never checked — a partial failure had no shutdown-level visibility. Now any escaped Exception is logged, and any False (a persist that did not confirm) is logged with the run_id. Added regression test test_shutdown_surfaces_failed_interrupted_persist. - deps: clarify the _RUN_DRAIN_TIMEOUT_SECONDS comment — state the actual value of _SHUTDOWN_HOOK_TIMEOUT_SECONDS (5.0s) and that both count toward the lifespan shutdown window. Kept as two separate constants (independent teardown steps that may diverge) rather than one shared "must match" value. - Verified no other test fake needs the shutdown stub: _FakeRunManager in test_worker_langfuse_metadata.py is a run_agent() argument (worker path), never injected into langgraph_runtime, so it never receives shutdown().	2026-06-07 11:24:30 +08:00

Xinmin Zeng	e93f658472	fix(stability): resolve P0 blockers from v2.0-m1-rc1 stability audit (#3107) (#3131) ... * fix(task-tool): unwrap callback manager when locating usage recorder `config["callbacks"]` may arrive as a `BaseCallbackManager` (e.g. the `AsyncCallbackManager` LangChain hands to async tool runs), not just a plain list. The previous `for cb in callbacks` loop raised `TypeError: 'AsyncCallbackManager' object is not iterable`, which `ToolErrorHandlingMiddleware` then converted into a failed `task` ToolMessage even though the subagent had completed internally — Ultra mode lost subagent results and the lead agent fell back to redoing the work. Unwrap `BaseCallbackManager.handlers` before searching for the recorder. Refs: bytedance/deer-flow#3107 (BUG-002) * fix(frontend): treat any task tool error as a terminal subtask failure The subtask card status machine matched only three English prefixes (`Task Succeeded. Result:`, `Task failed.`, `Task timed out`). Anything else fell through to `in_progress`, so a `task` tool error wrapped by `ToolErrorHandlingMiddleware` (`Error: Tool 'task' failed ...`) left the card spinning forever even after the run had ended. Extract the prefix logic into `parseSubtaskResult` and recognise any leading `Error:` token as a terminal failure. The extracted function is unit-tested against the legacy prefixes plus the `AsyncCallbackManager` regression captured in the upstream issue. Refs: bytedance/deer-flow#3107 (BUG-007) * fix(frontend): exclude hidden, reasoning, and tool payloads from chat export `formatThreadAsMarkdown` / `formatThreadAsJSON` iterated raw messages without running the UI-level `isHiddenFromUIMessage` filter. Exported transcripts therefore included `hide_from_ui` system reminders, memory injections, provider `reasoning_content`, tool calls, and tool result messages — content that is intentionally hidden in the chat view. Filter the export to the user-visible transcript by default and gate reasoning / tool calls / tool messages / hidden messages behind explicit `ExportOptions` flags so a future debug export can opt back in without forking the formatter. Refs: bytedance/deer-flow#3107 (BUG-006) * fix(gateway): route get_config through get_app_config for mtime hot reload `get_config(request)` returned the `app.state.config` snapshot captured at startup. The worker / lead-agent path then threaded that frozen `AppConfig` through `RunContext` and `agent_factory`, so per-run fields edited in `config.yaml` (notably `max_tokens`) were ignored until the gateway process was restarted — even though `get_app_config()` already does mtime-based reload at the bottom layer. Route the request dependency through `get_app_config()` directly. Runtime `ContextVar` overrides (`push_current_app_config`) and test-injected singletons (`set_app_config`) keep working; `app.state.config` is now only read at startup for one-shot bootstrap (logging level, IM channels, `langgraph_runtime` engines). `tests/test_gateway_deps_config.py` encoded the old snapshot contract and is removed; `tests/test_gateway_config_freshness.py` replaces it with mtime, ContextVar, and `set_app_config` coverage. `test_skills_custom_router.py` and `test_uploads_router.py` now inject test configs via FastAPI `dependency_overrides[get_config]` instead of mutating `app.state.config`. Document the hot-reload boundary in `backend/CLAUDE.md` so reviewers know which fields are picked up on the next request vs. which still require a restart (`database`, `checkpointer`, `run_events`, `stream_bridge`, `sandbox.use`, `log_level`, `channels.*`). Refs: bytedance/deer-flow#3107 (BUG-001) * fix(gateway): broaden get_config 503 to any config-load failure Address review feedback on the previous commit: 1. Narrow exception catch removed. The old contract returned 503 whenever `app.state.config is None`. The first cut only mapped `FileNotFoundError`, leaving `PermissionError`, YAML parse errors, and pydantic `ValidationError` to bubble up as 500. At the request boundary we treat any inability to materialise the config as "configuration not available" (503) and log the original exception so the operator still has the stack. 2. Removed the unused `request: Request` parameter and the matching `# noqa: ARG001`. FastAPI's `Depends()` does not require the dependency to accept `Request`; the only call site uses the no-arg form. 3. `backend/CLAUDE.md` boundary now lists the *reason* each field is restart-required (engine binding, singleton caching, one-shot `apply_logging_level`, etc.), not just the field name, so reviewers do not have to reverse-engineer the boundary themselves. Tests parametrise four exception classes (`FileNotFoundError`, `PermissionError`, `ValueError`, `RuntimeError`) and assert 503 for each. Refs: bytedance/deer-flow#3107 (BUG-001) * fix(task-tool): defend _find_usage_recorder against non-list callbacks Address review feedback. The previous commit handled the two common shapes LangChain hands to async tool runs — a plain `list[BaseCallbackHandler]` and a `BaseCallbackManager` subclass — but iterated any other shape directly, which would still raise `TypeError` if e.g. a single handler instance leaked through without a list wrapper. Treat any non-list, non-manager `config["callbacks"]` value as "no recorder" rather than crash. Docstring now lists all four shapes explicitly. New tests cover the single-handler-object case, `runtime is None`, `callbacks is None`, and `runtime.config` being a non-dict — all required to be silent no-ops. Refs: bytedance/deer-flow#3107 (BUG-002) * fix(frontend): drop dead identity ternary and add opt-in export tests Address review feedback on the previous export commit: 1. Removed the no-op `typeof msg.content === "string" ? msg.content : msg.content` expression in `formatThreadAsJSON`. Both branches returned the same value; the message content now flows through unchanged whether it is a string or the rich `MessageContent[]` shape (LangChain JSON-serialises the array structure correctly already). 2. Expanded the JSDoc on `ExportOptions` to make it clearer that the four flags are not currently wired to any UI control — callers wanting a debug export must build the options object explicitly. The default behaviour continues to match the explicit prescription in bytedance/deer-flow#3107 BUG-006. 3. Added opt-in coverage. The previous tests only exercised the `options = {}` default path; the new cases verify each flag flips the corresponding payload back into the export so a future debug-export surface does not silently break the contract. Refs: bytedance/deer-flow#3107 (BUG-006) * fix(frontend): export subtask prefix constants and document fallback intent Address review feedback on the previous BUG-007 commit: 1. `SUCCESS_PREFIX`, `FAILURE_PREFIX`, `TIMEOUT_PREFIX`, and the `ERROR_WRAPPER_PATTERN` regex are now exported. The JSDoc explicitly pins them as part of the backend↔frontend contract defined in `task_tool.py` and `tool_error_handling_middleware.py`, so any future structured-status migration (e.g. backend writing `additional_kwargs.subagent_status` instead of leading text) can reference these from one canonical place rather than redefine them. 2. The `in_progress` fallback now carries a docstring explaining the deliberate choice — LangChain only ever emits a `ToolMessage` once the tool itself has returned, so unrecognised content means the contract has drifted and "still running" is the right operator signal (eagerly marking it terminal-failed would mask the drift). No behaviour change; this is documentation and an API export. Refs: bytedance/deer-flow#3107 (BUG-007) * fix(gateway): drop app.state.config snapshot and freeze run_events_config Address @ShenAC-SAC's BUG-001 review on #3131. The previous cut still stored an ``AppConfig`` snapshot on ``app.state.config`` for startup bootstrap. Two follow-on hazards from that: 1. Future code touching the gateway lifespan could accidentally start reading ``app.state.config`` again, silently regressing the request hot path back to a stale snapshot. 2. ``get_run_context()`` paired a freshly-reloaded ``AppConfig`` with the startup-bound ``event_store`` and a *live* ``run_events_config`` field — so an operator who edited ``run_events.backend`` mid-flight would have produced a run context whose ``event_store`` and ``run_events_config`` referred to different backends. Clean approach (aligned with the direction in PR #3128): - ``lifespan()`` keeps a local ``startup_config`` variable and passes it explicitly into ``langgraph_runtime(app, startup_config)`` and into ``start_channel_service``. No ``app.state.config`` attribute is set at any point. - ``langgraph_runtime`` now accepts ``startup_config`` as a required parameter, removing the ``getattr(app.state, "config", None)`` lookup and the "config not initialised" runtime error. - The matching ``run_events_config`` is frozen onto ``app.state`` next to ``run_event_store`` so ``get_run_context`` reads the two from the same startup-time source. ``app_config`` continues to be resolved live via ``get_app_config()``. - ``backend/CLAUDE.md`` boundary explanation updated to spell out the ``startup_config`` / ``get_app_config()`` split. New regression test ``test_run_context_app_config_reflects_yaml_edit`` exercises the worker-feeding path: it asserts that ``ctx.app_config`` follows a mid-flight ``config.yaml`` edit while ``ctx.run_events_config`` stays frozen to the startup snapshot the event store was built from. Refs: bytedance/deer-flow#3107 (BUG-001), bytedance/deer-flow#3131 review * fix(frontend): parse Task cancelled and polling timed out as terminal Address @ShenAC-SAC's BUG-007 review on #3131. `task_tool.py` actually emits five terminal strings: - `Task Succeeded. Result: …` - `Task failed. …` - `Task timed out. …` - `Task cancelled by user.` ← previously matched none - `Task polling timed out after N minutes …` ← previously matched none The previous cut handled three; the last two fell through to the "unknown content" branch and pushed the subtask card back to `in_progress` even though the backend had already reached a terminal state. Add explicit matches plus regression tests for both. The `in_progress` fallback is now reserved for genuinely unrecognised output (i.e. contract drift), as documented. Refs: bytedance/deer-flow#3107 (BUG-007), bytedance/deer-flow#3131 review * fix(frontend): sanitize JSON export content via the Markdown content path Address @ShenAC-SAC's BUG-006 review and the Copilot inline comment on #3131. The previous cut filtered hidden/tool messages out of the JSON export but still serialised `msg.content` verbatim, so: - inline `<think>…</think>` wrappers stayed in the exported `content` even with `includeReasoning: false`, - content-array thinking blocks leaked the `thinking` field, - `<uploaded_files>…</uploaded_files>` markers leaked the workspace paths a user uploaded files to. JSON now goes through the same sanitiser the Markdown path uses (`extractContentFromMessage` + `stripUploadedFilesTag`). Reasoning and tool_calls remain gated behind their `ExportOptions` flags. AI / human rows that sanitise to empty content with no opted-in reasoning or tool calls are dropped so the JSON matches the Markdown path's `continue` on empty assistant fragments. New regression tests cover the three leak shapes the reviewer called out plus the empty-content-drop case. Refs: bytedance/deer-flow#3107 (BUG-006), bytedance/deer-flow#3131 review * test(gateway): align lifespan stub with langgraph_runtime two-arg signature Codex round-3 review of c0bc7a06 flagged this: changing `langgraph_runtime` to require `startup_config` as a second positional argument broke the one-arg stub `_noop_langgraph_runtime(_app)` in `test_gateway_lifespan_shutdown.py`, which is patched into `app.gateway.app.langgraph_runtime` by the lifespan shutdown bounded-timeout regression. Lifespan would then call the stub with two args and raise `TypeError` before the bounded-shutdown assertion ran. Update the stub to match the new signature. The shutdown test itself is unaffected — it only cares about the channel `stop_channel_service` hang path. Refs: bytedance/deer-flow#3107 (BUG-001), bytedance/deer-flow#3131 review * fix(frontend): strip every known backend marker in export, not just uploads Codex round-3 review of 258ca800 and the matching maintainer feedback on PR #3131 made the same point: the JSON export now ran the Markdown-side sanitiser, but that sanitiser only stripped `<uploaded_files>`. The full set of payloads middleware embeds inside message `content` is larger: - `<uploaded_files>` — `UploadsMiddleware` - `<system-reminder>` — `DynamicContextMiddleware` - `<memory>` — `DynamicContextMiddleware` (nested inside system-reminder) - `<current_date>` — `DynamicContextMiddleware` The primary protection is still `isHiddenFromUIMessage`: the `<system-reminder>` HumanMessage is marked `hide_from_ui: true` and never reaches the formatter. This commit adds the second line of defence so a regression that drops the `hide_from_ui` flag — or any future middleware that injects the same tag vocabulary into a visible HumanMessage — cannot leak the payload into the export file. Concrete changes: - New `INTERNAL_MARKER_TAGS` constant + `stripInternalMarkers(content)` helper in `core/messages/utils.ts`. The constant doubles as documentation for the backend↔frontend contract. - `formatMessageContent` in `export.ts` now calls `stripInternalMarkers` instead of `stripUploadedFilesTag`. UI render paths (`message-list-item.tsx`) keep using the narrower function so a user legitimately typing `<memory>` in a meta-discussion is preserved. - The "drop empty rows" guard in `buildJSONMessage` switched from `=== undefined` to truthy `!` checks. Codex spotted the asymmetry: when `extractReasoningContentFromMessage` returned the empty string (which it legitimately can), the JSON path emitted `{reasoning: ""}` while the Markdown path's `!reasoning` `continue` correctly dropped the row. New regression tests cover the defence-in-depth strip with a `<system-reminder><memory><current_date>` payload deliberately *not* marked `hide_from_ui`; tool-message sanitization under `includeToolMessages: true`; the mixed-content-array case (`thinking + text + image_url`); and the opted-in empty-reasoning drop. Live verification on a real Ultra-mode thread that uploaded a PDF (`曾鑫民-薪资交易流水.pdf`): backend state's first HumanMessage carries the `<uploaded_files>` block (with `/mnt/user-data/uploads/...` paths) as part of a content-array. The Markdown and JSON export blobs both come back free of `<uploaded_files>`, `<system-reminder>`, `<current_date>`, `tool_calls`, and reasoning — while preserving the user's `这是什么 ？` prompt and the assistant's visible answer. Refs: bytedance/deer-flow#3107 (BUG-006), bytedance/deer-flow#3131 review * test(frontend): cover trim, varied N, and pre-execution Error: prefixes Codex round-3 review of 50e2c257 flagged three coverage gaps in the subtask-status parser: 1. `Task cancelled by user.` and `Task polling timed out` previously had no whitespace-trim coverage — the original trim test only exercised the success prefix. Streaming chunks can arrive with leading/trailing newlines; the regex needed an explicit assertion. 2. The polling-timeout case was tested only at one `N` (15 minutes). The backend interpolates the live `timeout_seconds // 60` value, so the matcher must hold for any positive integer. Now we run the case for 1, 5, and 60 minutes. 3. `task_tool.py` also emits three `Error:` strings for pre-execution failures — unknown subagent type, host-bash disabled, and "task disappeared from background tasks". They are intentionally handled by `ERROR_WRAPPER_PATTERN` rather than dedicated prefixes (the wrapper already produces the right terminal-failed shape) but had no test coverage proving that wiring. Codex was right that a refactor splitting one of them off into its own prefix would silently break things. The JSDoc on the constants block now spells the three pre-execution errors out so the relationship between `task_tool.py` returns and the prefix vocabulary is explicit. No production code change beyond the docstring — this commit is pure coverage hardening for the contract that already exists.

JeffJiang	db5ad86381	feat: enhance chat history loading with new hooks and UI components (#2338) ... * Refactor API fetch calls to use a unified fetch function; enhance chat history loading with new hooks and UI components - Replaced `fetchWithAuth` with a generic `fetch` function across various API modules for consistency. - Updated `useThreadStream` and `useThreadHistory` hooks to manage chat history loading, including loading states and pagination. - Introduced `LoadMoreHistoryIndicator` component for better user experience when loading more chat history. - Enhanced message handling in `MessageList` to accommodate new loading states and history management. - Added support for run messages in the thread context, improving the overall message handling logic. - Updated translations for loading indicators in English and Chinese. * Fix test assertions for run ordering in RunManager tests - Updated assertions in `test_list_by_thread` to reflect correct ordering of runs. - Modified `test_list_by_thread_is_stable_when_timestamps_tie` to ensure stable ordering when timestamps are tied.	2026-04-26 11:20:17 +08:00
rayhpeng	56d5fa3337	feat(persistence):Unified persistence layer with event store, feedback, and rebase cleanup (#2134) ... * feat(persistence): add unified persistence layer with event store, token tracking, and feedback (#1930) * feat(persistence): add SQLAlchemy 2.0 async ORM scaffold Introduce a unified database configuration (DatabaseConfig) that controls both the LangGraph checkpointer and the DeerFlow application persistence layer from a single `database:` config section. New modules: - deerflow.config.database_config — Pydantic config with memory/sqlite/postgres backends - deerflow.persistence — async engine lifecycle, DeclarativeBase with to_dict mixin, Alembic skeleton - deerflow.runtime.runs.store — RunStore ABC + MemoryRunStore implementation Gateway integration initializes/tears down the persistence engine in the existing langgraph_runtime() context manager. Legacy checkpointer config is preserved for backward compatibility. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(persistence): add RunEventStore ABC + MemoryRunEventStore Phase 2-A prerequisite for event storage: adds the unified run event stream interface (RunEventStore) with an in-memory implementation, RunEventsConfig, gateway integration, and comprehensive tests (27 cases). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(persistence): add ORM models, repositories, DB/JSONL event stores, RunJournal, and API endpoints Phase 2-B: run persistence + event storage + token tracking. - ORM models: RunRow (with token fields), ThreadMetaRow, RunEventRow - RunRepository implements RunStore ABC via SQLAlchemy ORM - ThreadMetaRepository with owner access control - DbRunEventStore with trace content truncation and cursor pagination - JsonlRunEventStore with per-run files and seq recovery from disk - RunJournal (BaseCallbackHandler) captures LLM/tool/lifecycle events, accumulates token usage by caller type, buffers and flushes to store - RunManager now accepts optional RunStore for persistent backing - Worker creates RunJournal, writes human_message, injects callbacks - Gateway deps use factory functions (RunRepository when DB available) - New endpoints: messages, run messages, run events, token-usage - ThreadCreateRequest gains assistant_id field - 92 tests pass (33 new), zero regressions Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(persistence): add user feedback + follow-up run association Phase 2-C: feedback and follow-up tracking. - FeedbackRow ORM model (rating +1/-1, optional message_id, comment) - FeedbackRepository with CRUD, list_by_run/thread, aggregate stats - Feedback API endpoints: create, list, stats, delete - follow_up_to_run_id in RunCreateRequest (explicit or auto-detected from latest successful run on the thread) - Worker writes follow_up_to_run_id into human_message event metadata - Gateway deps: feedback_repo factory + getter - 17 new tests (14 FeedbackRepository + 3 follow-up association) - 109 total tests pass, zero regressions Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * test+config: comprehensive Phase 2 test coverage + deprecate checkpointer config - config.example.yaml: deprecate standalone checkpointer section, activate unified database:sqlite as default (drives both checkpointer + app data) - New: test_thread_meta_repo.py (14 tests) — full ThreadMetaRepository coverage including check_access owner logic, list_by_owner pagination - Extended test_run_repository.py (+4 tests) — completion preserves fields, list ordering desc, limit, owner_none returns all - Extended test_run_journal.py (+8 tests) — on_chain_error, track_tokens=false, middleware no ai_message, unknown caller tokens, convenience fields, tool_error, non-summarization custom event - Extended test_run_event_store.py (+7 tests) — DB batch seq continuity, make_run_event_store factory (memory/db/jsonl/fallback/unknown) - Extended test_phase2b_integration.py (+4 tests) — create_or_reject persists, follow-up metadata, summarization in history, full DB-backed lifecycle - Fixed DB integration test to use proper fake objects (not MagicMock) for JSON-serializable metadata - 157 total Phase 2 tests pass, zero regressions Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * config: move default sqlite_dir to .deer-flow/data Keep SQLite databases alongside other DeerFlow-managed data (threads, memory) under the .deer-flow/ directory instead of a top-level ./data folder. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * refactor(persistence): remove UTFJSON, use engine-level json_serializer + datetime.now() - Replace custom UTFJSON type with standard sqlalchemy.JSON in all ORM models. Add json_serializer=json.dumps(ensure_ascii=False) to all create_async_engine calls so non-ASCII text (Chinese etc.) is stored as-is in both SQLite and Postgres. - Change ORM datetime defaults from datetime.now(UTC) to datetime.now(), remove UTC imports. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * refactor(gateway): simplify deps.py with getter factory + inline repos - Replace 6 identical getter functions with _require() factory. - Inline 3 _make_*_repo() factories into langgraph_runtime(), call get_session_factory() once instead of 3 times. - Add thread_meta upsert in start_run (services.py). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(docker): add UV_EXTRAS build arg for optional dependencies Support installing optional dependency groups (e.g. postgres) at Docker build time via UV_EXTRAS build arg: UV_EXTRAS=postgres docker compose build Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * refactor(journal): fix flush, token tracking, and consolidate tests RunJournal fixes: - _flush_sync: retain events in buffer when no event loop instead of dropping them; worker's finally block flushes via async flush(). - on_llm_end: add tool_calls filter and caller=="lead_agent" guard for ai_message events; mark message IDs for dedup with record_llm_usage. - worker.py: persist completion data (tokens, message count) to RunStore in finally block. Model factory: - Auto-inject stream_usage=True for BaseChatOpenAI subclasses with custom api_base, so usage_metadata is populated in streaming responses. Test consolidation: - Delete test_phase2b_integration.py (redundant with existing tests). - Move DB-backed lifecycle test into test_run_journal.py. - Add tests for stream_usage injection in test_model_factory.py. - Clean up executor/task_tool dead journal references. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(events): widen content type to str|dict in all store backends Allow event content to be a dict (for structured OpenAI-format messages) in addition to plain strings. Dict values are JSON-serialized for the DB backend and deserialized on read; memory and JSONL backends handle dicts natively. Trace truncation now serializes dicts to JSON before measuring. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(events): use metadata flag instead of heuristic for dict content detection Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(converters): add LangChain-to-OpenAI message format converters Pure functions langchain_to_openai_message, langchain_to_openai_completion, langchain_messages_to_openai, and _infer_finish_reason for converting LangChain BaseMessage objects to OpenAI Chat Completions format, used by RunJournal for event storage. 15 unit tests added. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(converters): handle empty list content as null, clean up test Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(events): human_message content uses OpenAI user message format Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * feat(events): ai_message uses OpenAI format, add ai_tool_call message event - ai_message content now uses {"role": "assistant", "content": "..."} format - New ai_tool_call message event emitted when lead_agent LLM responds with tool_calls - ai_tool_call uses langchain_to_openai_message converter for consistent format - Both events include finish_reason in metadata ("stop" or "tool_calls") Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(events): add tool_result message event with OpenAI tool message format Cache tool_call_id from on_tool_start keyed by run_id as fallback for on_tool_end, then emit a tool_result message event (role=tool, tool_call_id, content) after each successful tool completion. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * feat(events): summary content uses OpenAI system message format Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(events): replace llm_start/llm_end with llm_request/llm_response in OpenAI format Add on_chat_model_start to capture structured prompt messages as llm_request events. Replace llm_end trace events with llm_response using OpenAI Chat Completions format. Track llm_call_index to pair request/response events. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(events): add record_middleware method for middleware trace events Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * test(events): add full run sequence integration test for OpenAI content format Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * feat(events): align message events with checkpoint format and add middleware tag injection - Message events (ai_message, ai_tool_call, tool_result, human_message) now use BaseMessage.model_dump() format, matching LangGraph checkpoint values.messages - on_tool_end extracts tool_call_id/name/status from ToolMessage objects - on_tool_error now emits tool_result message events with error status - record_middleware uses middleware:{tag} event_type and middleware category - Summarization custom events use middleware:summarize category - TitleMiddleware injects middleware:title tag via get_config() inheritance - SummarizationMiddleware model bound with middleware:summarize tag - Worker writes human_message using HumanMessage.model_dump() Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(threads): switch search endpoint to threads_meta table and sync title - POST /api/threads/search now queries threads_meta table directly, removing the two-phase Store + Checkpointer scan approach - Add ThreadMetaRepository.search() with metadata/status filters - Add ThreadMetaRepository.update_display_name() for title sync - Worker syncs checkpoint title to threads_meta.display_name on run completion - Map display_name to values.title in search response for API compatibility Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(threads): history endpoint reads messages from event store - POST /api/threads/{thread_id}/history now combines two data sources: checkpointer for checkpoint_id, metadata, title, thread_data; event store for messages (complete history, not truncated by summarization) - Strip internal LangGraph metadata keys from response - Remove full channel_values serialization in favor of selective fields Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: remove duplicate optional-dependencies header in pyproject.toml Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(middleware): pass tagged config to TitleMiddleware ainvoke call Without the config, the middleware:title tag was not injected, causing the LLM response to be recorded as a lead_agent ai_message in run_events. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: resolve merge conflict in .env.example Keep both DATABASE_URL (from persistence-scaffold) and WECOM credentials (from main) after the merge. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(persistence): address review feedback on PR #1851 - Fix naive datetime.now() → datetime.now(UTC) in all ORM models - Fix seq race condition in DbRunEventStore.put() with FOR UPDATE and UNIQUE(thread_id, seq) constraint - Encapsulate _store access in RunManager.update_run_completion() - Deduplicate _store.put() logic in RunManager via _persist_to_store() - Add update_run_completion to RunStore ABC + MemoryRunStore - Wire follow_up_to_run_id through the full create path - Add error recovery to RunJournal._flush_sync() lost-event scenario - Add migration note for search_threads breaking change - Fix test_checkpointer_none_fix mock to set database=None Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * chore: update uv.lock Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(persistence): address 22 review comments from CodeQL, Copilot, and Code Quality Bug fixes: - Sanitize log params to prevent log injection (CodeQL) - Reset threads_meta.status to idle/error when run completes - Attach messages only to latest checkpoint in /history response - Write threads_meta on POST /threads so new threads appear in search Lint fixes: - Remove unused imports (journal.py, migrations/env.py, test_converters.py) - Convert lambda to named function (engine.py, Ruff E731) - Remove unused logger definitions in repos (Ruff F841) - Add logging to JSONL decode errors and empty except blocks - Separate assert side-effects in tests (CodeQL) - Remove unused local variables in tests (Ruff F841) - Fix max_trace_content truncation to use byte length, not char length Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * style: apply ruff format to persistence and runtime files Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * Potential fix for pull request finding 'Statement has no effect' Co-authored-by: Copilot Autofix powered by AI <223894421+github-code-quality[bot]@users.noreply.github.com> * refactor(runtime): introduce RunContext to reduce run_agent parameter bloat Extract checkpointer, store, event_store, run_events_config, thread_meta_repo, and follow_up_to_run_id into a frozen RunContext dataclass. Add get_run_context() in deps.py to build the base context from app.state singletons. start_run() uses dataclasses.replace() to enrich per-run fields before passing ctx to run_agent. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * refactor(gateway): move sanitize_log_param to app/gateway/utils.py Extract the log-injection sanitizer from routers/threads.py into a shared utils module and rename to sanitize_log_param (public API). Eliminates the reverse service → router import in services.py. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * perf: use SQL aggregation for feedback stats and thread token usage Replace Python-side counting in FeedbackRepository.aggregate_by_run with a single SELECT COUNT/SUM query. Add RunStore.aggregate_tokens_by_thread abstract method with SQL GROUP BY implementation in RunRepository and Python fallback in MemoryRunStore. Simplify the thread_token_usage endpoint to delegate to the new method, eliminating the limit=10000 truncation risk. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * docs: annotate DbRunEventStore.put() as low-frequency path Add docstring clarifying that put() opens a per-call transaction with FOR UPDATE and should only be used for infrequent writes (currently just the initial human_message event). High-throughput callers should use put_batch() instead. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(threads): fall back to Store search when ThreadMetaRepository is unavailable When database.backend=memory (default) or no SQL session factory is configured, search_threads now queries the LangGraph Store instead of returning 503. Returns empty list if neither Store nor repo is available. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * refactor(persistence): introduce ThreadMetaStore ABC for backend-agnostic thread metadata Add ThreadMetaStore abstract base class with create/get/search/update/delete interface. ThreadMetaRepository (SQL) now inherits from it. New MemoryThreadMetaStore wraps LangGraph BaseStore for memory-mode deployments. deps.py now always provides a non-None thread_meta_repo, eliminating all `if thread_meta_repo is not None` guards in services.py, worker.py, and routers/threads.py. search_threads no longer needs a Store fallback branch. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * refactor(history): read messages from checkpointer instead of RunEventStore The /history endpoint now reads messages directly from the checkpointer's channel_values (the authoritative source) instead of querying RunEventStore.list_messages(). The RunEventStore API is preserved for other consumers. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(persistence): address new Copilot review comments - feedback.py: validate thread_id/run_id before deleting feedback - jsonl.py: add path traversal protection with ID validation - run_repo.py: parse `before` to datetime for PostgreSQL compat - thread_meta_repo.py: fix pagination when metadata filter is active - database_config.py: use resolve_path for sqlite_dir consistency Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * Implement skill self-evolution and skill_manage flow (#1874) * chore: ignore .worktrees directory * Add skill_manage self-evolution flow * Fix CI regressions for skill_manage * Address PR review feedback for skill evolution * fix(skill-evolution): preserve history on delete * fix(skill-evolution): tighten scanner fallbacks * docs: add skill_manage e2e evidence screenshot * fix(skill-manage): avoid blocking fs ops in session runtime --------- Co-authored-by: Willem Jiang <willem.jiang@gmail.com> * fix(config): resolve sqlite_dir relative to CWD, not Paths.base_dir resolve_path() resolves relative to Paths.base_dir (.deer-flow), which double-nested the path to .deer-flow/.deer-flow/data/app.db. Use Path.resolve() (CWD-relative) instead. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * Feature/feishu receive file (#1608) * feat(feishu): add channel file materialization hook for inbound messages - Introduce Channel.receive_file(msg, thread_id) as a base method for file materialization; default is no-op. - Implement FeishuChannel.receive_file to download files/images from Feishu messages, save to sandbox, and inject virtual paths into msg.text. - Update ChannelManager to call receive_file for any channel if msg.files is present, enabling downstream model access to user-uploaded files. - No impact on Slack/Telegram or other channels (they inherit the default no-op). * style(backend): format code with ruff for lint compliance - Auto-formatted packages/harness/deerflow/agents/factory.py and tests/test_create_deerflow_agent.py using `ruff format` - Ensured both files conform to project linting standards - Fixes CI lint check failures caused by code style issues * fix(feishu): handle file write operation asynchronously to prevent blocking * fix(feishu): rename GetMessageResourceRequest to _GetMessageResourceRequest and remove redundant code * test(feishu): add tests for receive_file method and placeholder replacement * fix(manager): remove unnecessary type casting for channel retrieval * fix(feishu): update logging messages to reflect resource handling instead of image * fix(feishu): sanitize filename by replacing invalid characters in file uploads * fix(feishu): improve filename sanitization and reorder image key handling in message processing * fix(feishu): add thread lock to prevent filename conflicts during file downloads * fix(test): correct bad merge in test_feishu_parser.py * chore: run ruff and apply formatting cleanup fix(feishu): preserve rich-text attachment order and improve fallback filename handling * fix(docker): restore gateway env vars and fix langgraph empty arg issue (#1915) Two production docker-compose.yaml bugs prevent `make up` from working: 1. Gateway missing DEER_FLOW_CONFIG_PATH and DEER_FLOW_EXTENSIONS_CONFIG_PATH environment overrides. Added in fb2d99f (#1836) but accidentally reverted by ca2fb95 (#1847). Without them, gateway reads host paths from .env via env_file, causing FileNotFoundError inside the container. 2. Langgraph command fails when LANGGRAPH_ALLOW_BLOCKING is unset (default). Empty $${allow_blocking} inserts a bare space between flags, causing ' --no-reload' to be parsed as unexpected extra argument. Fix by building args string first and conditionally appending --allow-blocking. Co-authored-by: cooper <cooperfu@tencent.com> * fix(frontend): resolve invalid HTML nesting and tabnabbing vulnerabilities (#1904) * fix(frontend): resolve invalid HTML nesting and tabnabbing vulnerabilities Fix `<button>` inside `<a>` invalid HTML in artifact components and add missing `noopener,noreferrer` to `window.open` calls to prevent reverse tabnabbing. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix(frontend): address Copilot review on tabnabbing and double-tab-open Remove redundant parent onClick on web_fetch ChainOfThoughtStep to prevent opening two tabs on link click, and explicitly null out window.opener after window.open() for defensive tabnabbing hardening. --------- Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com> * refactor(persistence): organize entities into per-entity directories Restructure the persistence layer from horizontal "models/ + repositories/" split into vertical entity-aligned directories. Each entity (thread_meta, run, feedback) now owns its ORM model, abstract interface (where applicable), and concrete implementations under a single directory with an aggregating __init__.py for one-line imports. Layout: persistence/thread_meta/{base,model,sql,memory}.py persistence/run/{model,sql}.py persistence/feedback/{model,sql}.py models/__init__.py is kept as a facade so Alembic autogenerate continues to discover all ORM tables via Base.metadata. RunEventRow remains under models/run_event.py because its storage implementation lives in runtime/events/store/db.py and has no matching repository directory. The repositories/ directory is removed entirely. All call sites in gateway/deps.py and tests are updated to import from the new entity packages, e.g.: from deerflow.persistence.thread_meta import ThreadMetaRepository from deerflow.persistence.run import RunRepository from deerflow.persistence.feedback import FeedbackRepository Full test suite passes (1690 passed, 14 skipped). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(gateway): sync thread rename and delete through ThreadMetaStore The POST /threads/{id}/state endpoint previously synced title changes only to the LangGraph Store via _store_upsert. In sqlite mode the search endpoint reads from the ThreadMetaRepository SQL table, so renames never appeared in /threads/search until the next agent run completed (worker.py syncs title from checkpoint to thread_meta in its finally block). Likewise the DELETE /threads/{id} endpoint cleaned up the filesystem, Store, and checkpointer but left the threads_meta row orphaned in sqlite, so deleted threads kept appearing in /threads/search. Fix both endpoints by routing through the ThreadMetaStore abstraction which already has the correct sqlite/memory implementations wired up by deps.py. The rename path now calls update_display_name() and the delete path calls delete() — both work uniformly across backends. Verified end-to-end with curl in gateway mode against sqlite backend. Existing test suite (1690 passed) and focused router/repo tests pass. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * refactor(gateway): route all thread metadata access through ThreadMetaStore Following the rename/delete bug fix in PR1, migrate the remaining direct LangGraph Store reads/writes in the threads router and services to the ThreadMetaStore abstraction so that the sqlite and memory backends behave identically and the legacy dual-write paths can be removed. Migrated endpoints (threads.py): - create_thread: idempotency check + write now use thread_meta_repo.get/create instead of dual-writing the LangGraph Store and the SQL row. - get_thread: reads from thread_meta_repo.get; the checkpoint-only fallback for legacy threads is preserved. - patch_thread: replaced _store_get/_store_put with thread_meta_repo.update_metadata. - delete_thread_data: dropped the legacy store.adelete; thread_meta_repo.delete already covers it. Removed dead code (services.py): - _upsert_thread_in_store — redundant with the immediately following thread_meta_repo.create() call. - _sync_thread_title_after_run — worker.py's finally block already syncs the title via thread_meta_repo.update_display_name() after each run. Removed dead code (threads.py): - _store_get / _store_put / _store_upsert helpers (no remaining callers). - THREADS_NS constant. - get_store import (router no longer touches the LangGraph Store directly). New abstract method: - ThreadMetaStore.update_metadata(thread_id, metadata) merges metadata into the thread's metadata field. Implemented in both ThreadMetaRepository (SQL, read-modify-write inside one session) and MemoryThreadMetaStore. Three new unit tests cover merge / empty / nonexistent behaviour. Net change: -134 lines. Full test suite: 1693 passed, 14 skipped. Verified end-to-end with curl in gateway mode against sqlite backend (create / patch / get / rename / search / delete).

Scope note: authz.py, test_auth.py, and test_auth_type_system.py are deferred to commit 2 because they depend on middleware and deps wiring that is not yet in place. Commit 1 stays "pure new files only" as the spec mandates. * feat(auth): wire auth end-to-end (middleware + frontend replacement) Backend: - Port auth_middleware, csrf_middleware, langgraph_auth, routers/auth - Port authz decorator (owner_filter_key defaults to 'owner_id') - Merge app.py: register AuthMiddleware + CSRFMiddleware + CORS, add _ensure_admin_user lifespan hook, _migrate_orphaned_threads helper, register auth router - Merge deps.py: add get_local_provider, get_current_user_from_request, get_optional_user_from_request; keep get_current_user as thin str|None adapter for feedback router - langgraph.json: add auth path pointing to langgraph_auth.py:auth - Rename metadata['user_id'] -> metadata['owner_id'] in langgraph_auth (both metadata write and LangGraph filter dict) + test fixtures Frontend: - Delete better-auth library and api catch-all route - Remove better-auth npm dependency and env vars (BETTER_AUTH_SECRET, BETTER_AUTH_GITHUB_*) from env.js - Port frontend/src/core/auth/* (AuthProvider, gateway-config, proxy-policy, server-side getServerSideUser, types) - Port frontend/src/core/api/fetcher.ts - Port (auth)/layout, (auth)/login, (auth)/setup pages - Rewrite workspace/layout.tsx as server component that calls getServerSideUser and wraps in AuthProvider - Port workspace/workspace-content.tsx for the client-side sidebar logic Tests: - Port 5 auth test files (test_auth, test_auth_middleware, test_auth_type_system, test_ensure_admin, test_langgraph_auth) - 176 auth tests PASS After this commit: login/logout/registration flow works, but persistence layer does not yet filter by owner_id. Commit 4 closes that gap. * feat(auth): account settings page + i18n - Port account-settings-page.tsx (change password, change email, logout) - Wire into settings-dialog.tsx as new "account" section with UserIcon, rendered first in the section list - Add i18n keys: - en-US/zh-CN: settings.sections.account ("Account" / "账号") - en-US/zh-CN: button.logout ("Log out" / "退出登录") - types.ts: matching type declarations * feat(auth): enforce owner_id across 2.0-rc persistence layer Add request-scoped contextvar-based owner filtering to threads_meta, runs, run_events, and feedback repositories. Router code is unchanged — isolation is enforced at the storage layer so that any caller that forgets to pass owner_id still gets filtered results, and new routes cannot accidentally leak data. Core infrastructure ------------------- - deerflow/runtime/user_context.py (new): - ContextVar[CurrentUser | None] with default None - runtime_checkable CurrentUser Protocol (structural subtype with .id) - set/reset/get/require helpers - AUTO sentinel + resolve_owner_id(value, method_name) for sentinel three-state resolution: AUTO reads contextvar, explicit str overrides, explicit None bypasses the filter (for migration/CLI) Repository changes ------------------ - ThreadMetaRepository: create/get/search/update_*/delete gain owner_id=AUTO kwarg; read paths filter by owner, writes stamp it, mutations check ownership before applying - RunRepository: put/get/list_by_thread/delete gain owner_id=AUTO kwarg - FeedbackRepository: create/get/list_by_run/list_by_thread/delete gain owner_id=AUTO kwarg - DbRunEventStore: list_messages/list_events/list_messages_by_run/ count_messages/delete_by_thread/delete_by_run gain owner_id=AUTO kwarg. Write paths (put/put_batch) read contextvar softly: when a request-scoped user is available, owner_id is stamped; background worker writes without a user context pass None which is valid (orphan row to be bound by migration) Schema ------ - persistence/models/run_event.py: RunEventRow.owner_id = Mapped[ str | None] = mapped_column(String(64), nullable=True, index=True) - No alembic migration needed: 2.0 ships fresh, Base.metadata.create_all picks up the new column automatically Middleware ---------- - auth_middleware.py: after cookie check, call get_optional_user_from_ request to load the real User, stamp it into request.state.user AND the contextvar via set_current_user, reset in a try/finally. Public paths and unauthenticated requests continue without contextvar, and @require_auth handles the strict 401 path Test infrastructure ------------------- - tests/conftest.py: @pytest.fixture(autouse=True) _auto_user_context sets a default SimpleNamespace(id="test-user-autouse") on every test unless marked @pytest.mark.no_auto_user. Keeps existing 20+ persistence tests passing without modification - pyproject.toml [tool.pytest.ini_options]: register no_auto_user marker so pytest does not emit warnings for opt-out tests - tests/test_user_context.py: 6 tests covering three-state semantics, Protocol duck typing, and require/optional APIs - tests/test_thread_meta_repo.py: one test updated to pass owner_id= None explicitly where it was previously relying on the old default Test results ------------ - test_user_context.py: 6 passed - test_auth*.py + test_langgraph_auth.py + test_ensure_admin.py: 127 - test_run_event_store / test_run_repository / test_thread_meta_repo / test_feedback: 92 passed - Full backend suite: 1905 passed, 2 failed (both @requires_llm flaky integration tests unrelated to auth), 1 skipped * feat(auth): extend orphan migration to 2.0-rc persistence tables _ensure_admin_user now runs a three-step pipeline on every boot: Step 1 (fatal): admin user exists / is created / password is reset Step 2 (non-fatal): LangGraph store orphan threads → admin Step 3 (non-fatal): SQL persistence tables → admin - threads_meta - runs - run_events - feedback Each step is idempotent. The fatal/non-fatal split mirrors PR #1728's original philosophy: admin creation failure blocks startup (the system is unusable without an admin), whereas migration failures log a warning and let the service proceed (a partial migration is recoverable; a missing admin is not). Key helpers ----------- - _iter_store_items(store, namespace, *, page_size=500): async generator that cursor-paginates across LangGraph store pages. Fixes PR #1728's hardcoded limit=1000 bug that would silently lose orphans beyond the first page. - _migrate_orphaned_threads(store, admin_user_id): Rewritten to use _iter_store_items. Returns the migrated count so the caller can log it; raises only on unhandled exceptions. - _migrate_orphan_sql_tables(admin_user_id): Imports the 4 ORM models lazily, grabs the shared session factory, runs one UPDATE per table in a single transaction, commits once. No-op when no persistence backend is configured (in-memory dev). Tests: test_ensure_admin.py (8 passed) * test(auth): port AUTH test plan docs + lint/format pass - Port backend/docs/AUTH_TEST_PLAN.md and AUTH_UPGRADE.md from PR #1728 - Rename metadata.user_id → metadata.owner_id in AUTH_TEST_PLAN.md (4 occurrences from the original PR doc) - ruff auto-fix UP037 in sentinel type annotations: drop quotes around "str | None | _AutoSentinel" now that from __future__ import annotations makes them implicit string forms - ruff format: 2 files (app/gateway/app.py, runtime/user_context.py) Note on test coverage additions: - conftest.py autouse fixture was already added in commit 4 (had to be co-located with the repository changes to keep pre-existing persistence tests passing) - cross-user isolation E2E tests (test_owner_isolation.py) deferred — enforcement is already proven by the 98-test repository suite via the autouse fixture + explicit _AUTO sentinel exercises - New test cases (TC-API-17..20, TC-ATK-13, TC-MIG-01..07) listed in AUTH_TEST_PLAN.md are deferred to a follow-up PR — they are manual-QA test cases rather than pytest code, and the spec-level coverage is already met by test_user_context.py + the 98-test repository suite. Final test results: - Auth suite (test_auth*, test_langgraph_auth, test_ensure_admin, test_user_context): 186 passed - Persistence suite (test_run_event_store, test_run_repository, test_thread_meta_repo, test_feedback): 98 passed - Lint: ruff check + ruff format both clean * test(auth): add cross-user isolation test suite 10 tests exercising the storage-layer owner filter by manually switching the user_context contextvar between two users. Verifies the safety invariant: After a repository write with owner_id=A, a subsequent read with owner_id=B must not return the row, and vice versa. Covers all 4 tables that own user-scoped data: TC-API-17 threads_meta — read, search, update, delete cross-user TC-API-18 runs — get, list_by_thread, delete cross-user TC-API-19 run_events — list_messages, list_events, count_messages, delete_by_thread (CRITICAL: raw conversation content leak vector) TC-API-20 feedback — get, list_by_run, delete cross-user Plus two meta-tests verifying the sentinel pattern itself: - AUTO + unset contextvar raises RuntimeError - explicit owner_id=None bypasses the filter (migration escape hatch) Architecture note ----------------- These tests bypass the HTTP layer by design. The full chain (cookie → middleware → contextvar → repository) is covered piecewise: - test_auth_middleware.py: middleware sets contextvar from cookies - test_owner_isolation.py: repositories enforce isolation when contextvar is set to different users Together they prove the end-to-end safety property without the ceremony of spinning up a full TestClient + in-memory DB for every router endpoint. Tests pass: 231 (full auth + persistence + isolation suite) Lint: clean * refactor(auth): migrate user repository to SQLAlchemy ORM Move the users table into the shared persistence engine so auth matches the pattern of threads_meta, runs, run_events, and feedback — one engine, one session factory, one schema init codepath. New files --------- - persistence/user/__init__.py, persistence/user/model.py: UserRow ORM class with partial unique index on (oauth_provider, oauth_id) - Registered in persistence/models/__init__.py so Base.metadata.create_all() picks it up Modified -------- - auth/repositories/sqlite.py: rewritten as async SQLAlchemy, identical constructor pattern to the other four repositories (def __init__(self, session_factory) + self._sf = session_factory) - auth/config.py: drop users_db_path field — storage is configured through config.database like every other table - deps.py/get_local_provider: construct SQLiteUserRepository with the shared session factory, fail fast if engine is not initialised - tests/test_auth.py: rewrite test_sqlite_round_trip_new_fields to use the shared engine (init_engine + close_engine in a tempdir) - tests/test_auth_type_system.py: add per-test autouse fixture that spins up a scratch engine and resets deps._cached_* singletons * refactor(auth): remove SQL orphan migration (unused in supported scenarios) The _migrate_orphan_sql_tables helper existed to bind NULL owner_id rows in threads_meta, runs, run_events, and feedback to the admin on first boot. But in every supported upgrade path, it's a no-op: 1. Fresh install: create_all builds fresh tables, no legacy rows 2. No-auth → with-auth (no existing persistence DB): persistence tables are created fresh by create_all, no legacy rows 3. No-auth → with-auth (has existing persistence DB from #1930): NOT a supported upgrade path — "有 DB 到有 DB" schema evolution is out of scope; users wipe DB or run manual ALTER So the SQL orphan migration never has anything to do in the supported matrix. Delete the function, simplify _ensure_admin_user from a 3-step pipeline to a 2-step one (admin creation + LangGraph store orphan migration only). LangGraph store orphan migration stays: it serves the real "no-auth → with-auth" upgrade path where a user's existing LangGraph thread metadata has no owner_id field and needs to be stamped with the newly-created admin's id. Tests: 284 passed (auth + persistence + isolation) Lint: clean * security(auth): write initial admin password to 0600 file instead of logs CodeQL py/clear-text-logging-sensitive-data flagged 3 call sites that logged the auto-generated admin password to stdout via logger.info(). Production log aggregators (ELK/Splunk/etc) would have captured those cleartext secrets. Replace with a shared helper that writes to .deer-flow/admin_initial_credentials.txt with mode 0600, and log only the path. New file -------- - app/gateway/auth/credential_file.py: write_initial_credentials() helper. Takes email, password, and a "initial"/"reset" label. Creates .deer-flow/ if missing, writes a header comment plus the email+password, chmods 0o600, returns the absolute Path. Modified -------- - app/gateway/app.py: both _ensure_admin_user paths (fresh creation + needs_setup password reset) now write to file and log the path - app/gateway/auth/reset_admin.py: rewritten to use the shared ORM repo (SQLiteUserRepository with session_factory) and the credential_file helper. The previous implementation was broken after the earlier ORM refactor — it still imported _get_users_conn and constructed SQLiteUserRepository() without a session factory. No tests changed — the three password-log sites are all exercised via existing test_ensure_admin.py which checks that startup succeeds, not that a specific string appears in logs. CodeQL alerts 272, 283, 284: all resolved. * security(auth): strict JWT validation in middleware (fix junk cookie bypass) AUTH_TEST_PLAN test 7.5.8 expects junk cookies to be rejected with 401. The previous middleware behaviour was "presence-only": check that some access_token cookie exists, then pass through. In combination with my Task-12 decision to skip @require_auth decorators on routes, this created a gap where a request with any cookie-shaped string (e.g. access_token=not-a-jwt) would bypass authentication on routes that do not touch the repository (/api/models, /api/mcp/config, /api/memory, /api/skills, …). Fix: middleware now calls get_current_user_from_request() strictly and catches the resulting HTTPException to render a 401 with the proper fine-grained error code (token_invalid, token_expired, user_not_found, …). On success it stamps request.state.user and the contextvar so repository-layer owner filters work downstream. The 4 old "_with_cookie_passes" tests in test_auth_middleware.py were written for the presence-only behaviour; they asserted that a junk cookie would make the handler return 200. They are renamed to "_with_junk_cookie_rejected" and their assertions flipped to 401. The negative path (no cookie → 401 not_authenticated) is unchanged. Verified: no cookie → 401 not_authenticated junk cookie → 401 token_invalid (the fixed bug) expired cookie → 401 token_expired Tests: 284 passed (auth + persistence + isolation) Lint: clean * security(auth): wire @require_permission(owner_check=True) on isolation routes Apply the require_permission decorator to all 28 routes that take a {thread_id} path parameter. Combined with the strict middleware (previous commit), this gives the double-layer protection that AUTH_TEST_PLAN test 7.5.9 documents: Layer 1 (AuthMiddleware): cookie + JWT validation, rejects junk cookies and stamps request.state.user Layer 2 (@require_permission with owner_check=True): per-resource ownership verification via ThreadMetaStore.check_access — returns 404 if a different user owns the thread The decorator's owner_check branch is rewritten to use the SQL thread_meta_repo (the 2.0-rc persistence layer) instead of the LangGraph store path that PR #1728 used (_store_get / get_store in routers/threads.py). The inject_record convenience is dropped — no caller in 2.0 needs the LangGraph blob, and the SQL repo has a different shape. Routes decorated (28 total): - threads.py: delete, patch, get, get-state, post-state, post-history - thread_runs.py: post-runs, post-runs-stream, post-runs-wait, list_runs, get_run, cancel_run, join_run, stream_existing_run, list_thread_messages, list_run_messages, list_run_events, thread_token_usage - feedback.py: create, list, stats, delete - uploads.py: upload (added Request param), list, delete - artifacts.py: get_artifact - suggestions.py: generate (renamed body parameter to avoid conflict with FastAPI Request) Test fixes: - test_suggestions_router.py: bypass the decorator via __wrapped__ (the unit tests cover parsing logic, not auth — no point spinning up a thread_meta_repo just to test JSON unwrapping) - test_auth_middleware.py 4 fake-cookie tests: already updated in the previous commit (745bf432) Tests: 293 passed (auth + persistence + isolation + suggestions) Lint: clean * security(auth): defense-in-depth fixes from release validation pass Eight findings caught while running the AUTH_TEST_PLAN end-to-end against the deployed sg_dev stack. Each is a pre-condition for shipping release/2.0-rc that the previous PRs missed. Backend hardening - routers/auth.py: rate limiter X-Real-IP now requires AUTH_TRUSTED_PROXIES whitelist (CIDR/IP allowlist). Without nginx in front, the previous code honored arbitrary X-Real-IP, letting an attacker rotate the header to fully bypass the per-IP login lockout. - routers/auth.py: 36-entry common-password blocklist via Pydantic field_validator on RegisterRequest + ChangePasswordRequest. The shared _validate_strong_password helper keeps the constraint in one place. - routers/threads.py: ThreadCreateRequest + ThreadPatchRequest strip server-reserved metadata keys (owner_id, user_id) via Pydantic field_validator so a forged value can never round-trip back to other clients reading the same thread. The actual ownership invariant stays on the threads_meta row; this closes the metadata-blob echo gap. - authz.py + thread_meta/sql.py: require_permission gains a require_existing flag plumbed through check_access(require_existing=True). Destructive routes (DELETE/PATCH/state-update/runs/feedback) now treat a missing thread_meta row as 404 instead of "untracked legacy thread, allow", closing the cross-user delete-idempotence gap where any user could successfully DELETE another user's deleted thread. - repositories/sqlite.py + base.py: update_user raises UserNotFoundError on a vanished row instead of silently returning the input. Concurrent delete during password reset can no longer look like a successful update. - runtime/user_context.py: resolve_owner_id() coerces User.id (UUID) to str at the contextvar boundary so SQLAlchemy String(64) columns can bind it. The whole 2.0-rc isolation pipeline was previously broken end-to-end (POST /api/threads → 500 "type 'UUID' is not supported"). - persistence/engine.py: SQLAlchemy listener enables PRAGMA journal_mode=WAL, synchronous=NORMAL, foreign_keys=ON on every new SQLite connection. TC-UPG-06 in the test plan expects WAL; previous code shipped with the default 'delete' journal. - auth_middleware.py: stamp request.state.auth = AuthContext(...) so @require_permission's short-circuit fires; previously every isolation request did a duplicate JWT decode + users SELECT. Also unifies the 401 payload through AuthErrorResponse(...).model_dump(). - app.py: _ensure_admin_user restructure removes the noqa F821 scoping bug where 'password' was referenced outside the branch that defined it. New _announce_credentials helper absorbs the duplicate log block in the fresh-admin and reset-admin branches. * fix(frontend+nginx): rollout CSRF on every state-changing client path The frontend was 100% broken in gateway-pro mode for any user trying to open a specific chat thread. Three cumulative bugs each silently masked the next. LangGraph SDK CSRF gap (api-client.ts) - The Client constructor took only apiUrl, no defaultHeaders, no fetch interceptor. The SDK's internal fetch never sent X-CSRF-Token, so every state-changing /api/langgraph-compat/* call (runs/stream, threads/search, threads/{tid}/history, ...) hit CSRFMiddleware and got 403 before reaching the auth check. UI symptom: empty thread page with no error message; the SPA's hooks swallowed the rejection. - Fix: pass an onRequest hook that injects X-CSRF-Token from the csrf_token cookie per request. Reading the cookie per call (not at construction time) handles login / logout / password-change cookie rotation transparently. The SDK's prepareFetchOptions calls onRequest for both regular requests AND streaming/SSE/reconnect, so the same hook covers runs.stream and runs.joinStream. Raw fetch CSRF gap (7 files) - Audit: 11 frontend fetch sites, only 2 included CSRF (login/setup + account-settings change-password). The other 7 routed through raw fetch() with no header — suggestions, memory, agents, mcp, skills, uploads, and the local thread cleanup hook all 403'd silently. - Fix: enhance fetcher.ts:fetchWithAuth to auto-inject X-CSRF-Token on POST/PUT/DELETE/PATCH from a single shared readCsrfCookie() helper. Convert all 7 raw fetch() callers to fetchWithAuth so the contract is centrally enforced. api-client.ts and fetcher.ts share readCsrfCookie + STATE_CHANGING_METHODS to avoid drift. nginx routing + buffering (nginx.local.conf) - The auth feature shipped without updating the nginx config: per-API explicit location blocks but no /api/v1/auth/, /api/feedback, /api/runs. The frontend's client-side fetches to /api/v1/auth/login/local 404'd from the Next.js side because nginx routed /api/* to the frontend. - Fix: add catch-all `location /api/` that proxies to the gateway. nginx longest-prefix matching keeps the explicit blocks (/api/models, /api/threads regex, /api/langgraph/, ...) winning for their paths. - Fix: disable proxy_buffering + proxy_request_buffering for the frontend `location /` block. Without it, nginx tries to spool large Next.js chunks into /var/lib/nginx/proxy (root-owned) and fails with Permission denied → ERR_INCOMPLETE_CHUNKED_ENCODING → ChunkLoadError. * test(auth): release-validation test infra and new coverage Test fixtures and unit tests added during the validation pass. Router test helpers (NEW: tests/_router_auth_helpers.py) - make_authed_test_app(): builds a FastAPI test app with a stub middleware that stamps request.state.user + request.state.auth and a permissive thread_meta_repo mock. TestClient-based router tests (test_artifacts_router, test_threads_router) use it instead of bare FastAPI() so the new @require_permission(owner_check=True) decorators short-circuit cleanly. - call_unwrapped(): walks the __wrapped__ chain to invoke the underlying handler without going through the authz wrappers. Direct-call tests (test_uploads_router) use it. Typed with ParamSpec so the wrapped signature flows through. Backend test additions - test_auth.py: 7 tests for the new _get_client_ip trust model (no proxy / trusted proxy / untrusted peer / XFF rejection / invalid CIDR / no client). 5 tests for the password blocklist (literal, case-insensitive, strong password accepted, change-password binding, short-password length-check still fires before blocklist). test_update_user_raises_when_row_concurrently_deleted: closes a shipped-without-coverage gap on the new UserNotFoundError contract. - test_thread_meta_repo.py: 4 tests for check_access(require_existing=True) — strict missing-row denial, strict owner match, strict owner mismatch, strict null-owner still allowed (shared rows survive the tightening). - test_ensure_admin.py: 3 tests for _migrate_orphaned_threads / _iter_store_items pagination, covering the TC-UPG-02 upgrade story end-to-end via mock store. Closes the gap where the cursor pagination was untested even though the previous PR rewrote it. - test_threads_router.py: 5 tests for _strip_reserved_metadata (owner_id removal, user_id removal, safe-keys passthrough, empty input, both-stripped). - test_auth_type_system.py: replace "password123" fixtures with Tr0ub4dor3a / AnotherStr0ngPwd! so the new password blocklist doesn't reject the test data. * docs(auth): refresh TC-DOCKER-05 + document Docker validation gap - AUTH_TEST_PLAN.md TC-DOCKER-05: the previous expectation ("admin password visible in docker logs") was stale after the simplify pass that moved credentials to a 0600 file. The grep "Password:" check would have silently failed and given a false sense of coverage. New expectation matches the actual file-based path: 0600 file in DEER_FLOW_HOME, log shows the path (not the secret), reverse-grep asserts no leaked password in container logs. - NEW: docs/AUTH_TEST_DOCKER_GAP.md documents the only un-executed block in the test plan (TC-DOCKER-01..06). Reason: sg_dev validation host has no Docker daemon installed. The doc maps each Docker case to an already-validated bare-metal equivalent (TC-1.1, TC-REENT-01, TC-API-02 etc.) so the gap is auditable, and includes pre-flight reproduction steps for whoever has Docker available. --------- Co-authored-by: greatmengqi <chenmengqi.0376@bytedance.com> * refactor(persistence): unify SQLite to single deerflow.db and move checkpointer to runtime Merge checkpoints.db and app.db into a single deerflow.db file (WAL mode handles concurrent access safely).

User.id is a Pydantic UUID, and aiosqlite cannot bind a raw UUID object to a VARCHAR column, so the INSERT for the initial human_message event silently rolled back and raised out of the worker task. Because that put() sat outside the worker's try block, the finally-clause that publishes end-of-stream never ran and the SSE stream hung forever. jsonl mode was unaffected because json.dumps(default=str) coerces UUID objects transparently. Fixes: - db.py: coerce user.id to str at the context-read boundary (matches what resolve_user_id already does for the other repositories) - worker.py: move RunJournal init + human_message put inside the try block so any failure flows through the finally/publish_end path instead of hanging the subscriber Defense-in-depth: - engine.py: add PRAGMA busy_timeout=5000 so checkpointer and event store wait for each other on the shared deerflow.db file instead of failing immediately under write-lock contention - journal.py: skip fire-and-forget _flush_sync when a previous flush task is still in flight, to avoid piling up concurrent put_batch writes on the same SQLAlchemy engine during streaming; flush() now waits for pending tasks before draining the buffer - database_config.py: doc-only update clarifying WAL + busy_timeout keep the unified deerflow.db safe for both workloads Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * chore(persistence): drop redundant busy_timeout PRAGMA Python's sqlite3 driver defaults to a 5-second busy timeout via the ``timeout`` kwarg of ``sqlite3.connect``, and aiosqlite + SQLAlchemy's aiosqlite dialect inherit that default. Setting ``PRAGMA busy_timeout=5000`` explicitly was a no-op — verified by reading back the PRAGMA on a fresh connection (it already reports 5000ms without our PRAGMA). Concurrent stress test (50 checkpoint writes + 20 event batches + 50 thread_meta updates on the same deerflow.db) still completes with zero errors and 200/200 rows after removing the explicit PRAGMA. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(journal): unwrap Command tool results in on_tool_end Tools that update graph state (e.g. ``present_files``) return ``Command(update={'messages': [ToolMessage(...)], 'artifacts': [...]})``. LangGraph later unwraps the inner ``ToolMessage`` into checkpoint state, but ``RunJournal.on_tool_end`` was receiving the ``Command`` object directly via the LangChain callback chain and storing ``str(Command(update={...}))`` as the tool_result content. This produced a visible divergence between the event-store and the checkpoint for any thread that used a Command-returning tool, blocking the event-store-backed history fix in the follow-up commit. Concrete example from thread ``6d30913e-dcd4-41c8-8941-f66c716cf359`` (seq=48): checkpoint had ``'Successfully presented files'`` while event_store stored the full Command repr. The fix detects ``Command`` in ``on_tool_end``, extracts the first ``ToolMessage`` from ``update['messages']``, and lets the existing ToolMessage branch handle the ``model_dump()`` path. Legacy rows still containing the Command repr are separately cleaned up by the history helper in the follow-up commit. Tests: - ``test_tool_end_unwraps_command_with_inner_tool_message`` — unit test of the unwrap branch with a constructed Command - ``test_tool_invoke_end_to_end_unwraps_command`` — end-to-end via ``CallbackManager`` + ``tool.invoke`` to exercise the real LangChain dispatch path that production uses, matching the repro shape from ``present_files`` - Counter-proof: temporarily reverted the patch, both tests failed with the exact ``Command(update={...})`` repr that was stored in the production SQLite row at seq=48, confirming LangChain does pass the ``Command`` through callbacks (the unwrap is load-bearing) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(threads): load history messages from event store, immune to summarize ``get_thread_history`` and ``get_thread_state`` in Gateway mode read messages from ``checkpoint.channel_values["messages"]``. After SummarizationMiddleware runs mid-run, that list is rewritten in-place: pre-summarize messages are dropped and a synthetic summary-as-human message takes position 0. The frontend then renders a chat history that starts with ``"Here is a summary of the conversation to date:..."`` instead of the user's original query, and all earlier turns are gone. The event store (``RunEventStore``) is append-only and never rewritten, so it retains the full transcript. This commit adds a helper ``_get_event_store_messages`` that loads the event store's message stream and overrides ``values["messages"]`` in both endpoints; the checkpoint fallback kicks in only when the event store is unavailable. Behavior contract of the helper: - **Full pagination.** ``list_messages`` returns the newest ``limit`` records when no cursor is given, so a fixed limit silently drops older messages on long threads. The helper sizes the read from ``count_messages()`` and pages forward with ``after_seq`` cursors. - **Copy-on-read.** Each content dict is copied before ``id`` is patched so the live store object (``MemoryRunEventStore`` returns references) is never mutated. - **Stable ids.** Messages with ``id=None`` (human + tool_result, which don't receive an id until checkpoint persistence) get a deterministic ``uuid5(NAMESPACE_URL, f"{thread_id}:{seq}")`` so React keys stay stable across requests. AI messages keep their LLM-assigned ``lc_run--*`` ids. - **Legacy ``Command`` repr sanitization.** Rows captured before the ``journal.py`` ``on_tool_end`` fix (previous commit) stored ``str(Command(update={'messages': [ToolMessage(content='X', ...)]}))`` as the tool_result content. ``_sanitize_legacy_command_repr`` regex-extracts the inner text so old threads render cleanly. - **Inline feedback.** When loading the stream, the helper also pulls ``feedback_repo.list_by_thread_grouped`` and attaches ``run_id`` to every message plus ``feedback`` to the final ``ai_message`` of each run. This removes the frontend's need to fetch a second endpoint and positional-index-map its way back to the right run. When the feedback subsystem is unavailable, the ``feedback`` field is left absent entirely so the frontend hides the button rather than rendering it over a broken write path. - **User context.** ``DbRunEventStore`` is user-scoped by default via ``resolve_user_id(AUTO)``. The helper relies on the ``@require_permission`` decorator having populated the user contextvar on both callers; the docstring documents this dependency explicitly so nobody wires it into a CLI or migration script without passing ``user_id=None``. Real data verification against thread ``6d30913e-dcd4-41c8-8941-f66c716cf359``: checkpoint showed 12 messages (summarize-corrupted), event store had 16. The original human message ``"最新伊美局势"`` was preserved as seq=1 in the event store and correctly restored to position 0 in the helper output. Helper output for AI messages was byte-identical to checkpoint for every overlapping message; only tool_result ids differed (patched to uuid5) and the legacy Command repr at seq=48 was sanitized. Tests: - ``test_thread_state_event_store.py`` — 18 tests covering ``_sanitize_legacy_command_repr`` (passthrough, single/double-quote extraction, unparseable fallback), helper happy path (all message types, stable uuid5, store non-mutation), multi-page pagination, summarize regression (recovers pre-summarize messages), feedback attachment (per-run, multi-run threads, repo failure graceful), and dependency failure fallback to ``None``. Docs: - ``docs/superpowers/plans/2026-04-10-event-store-history.md`` — the implementation plan this commit realizes, with Task 1 revised after the evaluation findings (pagination, copy-on-read, Command wrap already landed in journal.py, frontend feedback pagination in the follow-up commit, Standard-mode follow-up noted). - ``docs/superpowers/specs/2026-04-11-runjournal-history-evaluation.md`` — the Claude + second-opinion evaluation document that drove the plan revisions (pagination bug, dict-mutation bug, feedback hidden bug, Command bug). - ``docs/superpowers/specs/2026-04-11-summarize-marker-design.md`` — design for a follow-up PR that visually marks summarize events in history, based on a verified ``adispatch_custom_event`` experiment (``trace=False`` middleware nodes can still forward the Pregel task config via explicit signature injection). Scope: Gateway mode only (``make dev-pro``). Standard mode (``make dev``) hits LangGraph Server directly and bypasses these endpoints; the summarize symptom is still present there and is tracked as a separate follow-up in the plan. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * refactor(feedback): inline feedback on history and drop positional mapping The old ``useThreadFeedback`` hook loaded ``GET /api/threads/{id}/messages?limit=200`` and built two parallel lookup tables: ``runIdByAiIndex`` (an ordinal array of run_ids for every ``ai_message``-typed event) and ``feedbackByRunId``. The render loop in ``message-list.tsx`` walked the AI messages in order, incrementing ``aiMessageIndex`` on each non-human message, and used that ordinal to look up the run_id and feedback. This shape had three latent bugs we could observe on real threads: 1. **Fetch was capped at 200 messages.** Long or tool-heavy threads silently dropped earlier entries from the map, so feedback buttons could be missing on messages they should own. 2. **Ordinal mismatch.** The render loop counted every non-human message (including each intermediate ``ai_tool_call``), but ``runIdByAiIndex`` only pushed entries for ``event_type == "ai_message"``. A run with 3 tool_calls + 1 final AI message would push 1 entry while the render consumed 4 positions, so buttons mapped to the wrong positions across multi-run threads. 3. **Two parallel data paths.** The ``/history`` render path and the ``/messages`` feedback-lookup path could drift in-between an ``invalidateQueries`` call and the next refetch, producing transient mismaps. The previous commit moved the authoritative message source for history to the event store and added ``run_id`` + ``feedback`` inline on each message dict returned by ``_get_event_store_messages``. This commit aligns the frontend with that contract: - **Delete** ``useThreadFeedback``, ``ThreadFeedbackData``, ``runIdByAiIndex``, ``feedbackByRunId``, and ``fetchAllThreadMessages``. - **Introduce** ``useThreadMessageEnrichment`` that fetches ``POST /history?limit=1`` once, indexes the returned messages by ``message.id`` into a ``Map<id, {run_id, feedback?}>``, and invalidates on stream completion (``onFinish`` in ``useThreadStream``). Keying by ``message.id`` is stable across runs, tool_call chains, and summarize. - **Simplify** ``message-list.tsx`` to drop the ``aiMessageIndex`` counter and read ``enrichment?.get(msg.id)`` at each render step. - **Rewire** ``message-list-item.tsx`` so the feedback button renders when ``feedback !== undefined`` rather than when the message happens to be non-human. ``feedback`` is ``undefined`` for non-eligible messages (humans, non-final AI, tools), ``null`` for the final ai_message of an unrated run, and a ``FeedbackData`` object once rated — cleanly distinguishing "not eligible" from "eligible but unrated". ``/api/threads/{id}/messages`` is kept as a debug/export surface; no frontend code calls it anymore but the backend router is untouched. Validation: - ``pnpm check`` clean (0 errors, 1 pre-existing unrelated warning) - Live test on thread ``3d5dea4a`` after gateway restart confirmed the original user query is restored to position 0 and the feedback button behaves correctly on the final AI message.

Also update checkpointer imports from the old deerflow.agents.checkpointer path to deerflow.runtime.checkpointer, and clean up orphaned feedback props in the frontend message components. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(rebase): restore FeedbackButtons component and enrichment lost during rebase The FeedbackButtons component (defined inline in message-list-item.tsx) was introduced in commit 95df8d13 but lost during rebase. The previous rebase cleanup commit incorrectly removed the feedback/runId props and enrichment hook as "orphaned code" instead of restoring the missing component. This commit restores: - FeedbackButtons component with thumbs up/down toggle and optimistic state - FeedbackData/upsertFeedback/deleteFeedback imports - feedback and runId props on MessageListItem - useThreadMessageEnrichment hook and entry lookup in message-list.tsx Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.6 (1M context) <noreply@anthropic.com> Co-authored-by: Copilot Autofix powered by AI <223894421+github-code-quality[bot]@users.noreply.github.com> Co-authored-by: DanielWalnut <45447813+hetaoBackend@users.noreply.github.com> Co-authored-by: Willem Jiang <willem.jiang@gmail.com> Co-authored-by: JilongSun <965640067@qq.com> Co-authored-by: jie <49781832+stan-fu@users.noreply.github.com> Co-authored-by: cooper <cooperfu@tencent.com> Co-authored-by: yangzheli <43645580+yangzheli@users.noreply.github.com> Co-authored-by: greatmengqi <chenmengqi.0376@gmail.com> Co-authored-by: greatmengqi <chenmengqi.0376@bytedance.com>	2026-04-26 11:09:55 +08:00
greatmengqi	94eee95fe0	feat(auth): release-validation pass for 2.0-rc — 12 blockers + simplify follow-ups (#2008) ... * feat(auth): introduce backend auth module Port RFC-001 authentication core from PR #1728: - JWT token handling (create_access_token, decode_token, TokenPayload) - Password hashing (bcrypt) with verify_password - SQLite UserRepository with base interface - Provider Factory pattern (LocalAuthProvider) - CLI reset_admin tool - Auth-specific errors (AuthErrorCode, TokenError, AuthErrorResponse) Deps: - bcrypt>=4.0.0 - pyjwt>=2.9.0 - email-validator>=2.0.0 - backend/uv.toml pins public PyPI index Tests: 12 pure unit tests (test_auth_config.py, test_auth_errors.py). Scope note: authz.py, test_auth.py, and test_auth_type_system.py are deferred to commit 2 because they depend on middleware and deps wiring that is not yet in place. Commit 1 stays "pure new files only" as the spec mandates. * feat(auth): wire auth end-to-end (middleware + frontend replacement) Backend: - Port auth_middleware, csrf_middleware, langgraph_auth, routers/auth - Port authz decorator (owner_filter_key defaults to 'owner_id') - Merge app.py: register AuthMiddleware + CSRFMiddleware + CORS, add _ensure_admin_user lifespan hook, _migrate_orphaned_threads helper, register auth router - Merge deps.py: add get_local_provider, get_current_user_from_request, get_optional_user_from_request; keep get_current_user as thin str|None adapter for feedback router - langgraph.json: add auth path pointing to langgraph_auth.py:auth - Rename metadata['user_id'] -> metadata['owner_id'] in langgraph_auth (both metadata write and LangGraph filter dict) + test fixtures Frontend: - Delete better-auth library and api catch-all route - Remove better-auth npm dependency and env vars (BETTER_AUTH_SECRET, BETTER_AUTH_GITHUB_*) from env.js - Port frontend/src/core/auth/* (AuthProvider, gateway-config, proxy-policy, server-side getServerSideUser, types) - Port frontend/src/core/api/fetcher.ts - Port (auth)/layout, (auth)/login, (auth)/setup pages - Rewrite workspace/layout.tsx as server component that calls getServerSideUser and wraps in AuthProvider - Port workspace/workspace-content.tsx for the client-side sidebar logic Tests: - Port 5 auth test files (test_auth, test_auth_middleware, test_auth_type_system, test_ensure_admin, test_langgraph_auth) - 176 auth tests PASS After this commit: login/logout/registration flow works, but persistence layer does not yet filter by owner_id. Commit 4 closes that gap. * feat(auth): account settings page + i18n - Port account-settings-page.tsx (change password, change email, logout) - Wire into settings-dialog.tsx as new "account" section with UserIcon, rendered first in the section list - Add i18n keys: - en-US/zh-CN: settings.sections.account ("Account" / "账号") - en-US/zh-CN: button.logout ("Log out" / "退出登录") - types.ts: matching type declarations * feat(auth): enforce owner_id across 2.0-rc persistence layer Add request-scoped contextvar-based owner filtering to threads_meta, runs, run_events, and feedback repositories. Router code is unchanged — isolation is enforced at the storage layer so that any caller that forgets to pass owner_id still gets filtered results, and new routes cannot accidentally leak data. Core infrastructure ------------------- - deerflow/runtime/user_context.py (new): - ContextVar[CurrentUser | None] with default None - runtime_checkable CurrentUser Protocol (structural subtype with .id) - set/reset/get/require helpers - AUTO sentinel + resolve_owner_id(value, method_name) for sentinel three-state resolution: AUTO reads contextvar, explicit str overrides, explicit None bypasses the filter (for migration/CLI) Repository changes ------------------ - ThreadMetaRepository: create/get/search/update_*/delete gain owner_id=AUTO kwarg; read paths filter by owner, writes stamp it, mutations check ownership before applying - RunRepository: put/get/list_by_thread/delete gain owner_id=AUTO kwarg - FeedbackRepository: create/get/list_by_run/list_by_thread/delete gain owner_id=AUTO kwarg - DbRunEventStore: list_messages/list_events/list_messages_by_run/ count_messages/delete_by_thread/delete_by_run gain owner_id=AUTO kwarg. Write paths (put/put_batch) read contextvar softly: when a request-scoped user is available, owner_id is stamped; background worker writes without a user context pass None which is valid (orphan row to be bound by migration) Schema ------ - persistence/models/run_event.py: RunEventRow.owner_id = Mapped[ str | None] = mapped_column(String(64), nullable=True, index=True) - No alembic migration needed: 2.0 ships fresh, Base.metadata.create_all picks up the new column automatically Middleware ---------- - auth_middleware.py: after cookie check, call get_optional_user_from_ request to load the real User, stamp it into request.state.user AND the contextvar via set_current_user, reset in a try/finally. Public paths and unauthenticated requests continue without contextvar, and @require_auth handles the strict 401 path Test infrastructure ------------------- - tests/conftest.py: @pytest.fixture(autouse=True) _auto_user_context sets a default SimpleNamespace(id="test-user-autouse") on every test unless marked @pytest.mark.no_auto_user. Keeps existing 20+ persistence tests passing without modification - pyproject.toml [tool.pytest.ini_options]: register no_auto_user marker so pytest does not emit warnings for opt-out tests - tests/test_user_context.py: 6 tests covering three-state semantics, Protocol duck typing, and require/optional APIs - tests/test_thread_meta_repo.py: one test updated to pass owner_id= None explicitly where it was previously relying on the old default Test results ------------ - test_user_context.py: 6 passed - test_auth*.py + test_langgraph_auth.py + test_ensure_admin.py: 127 - test_run_event_store / test_run_repository / test_thread_meta_repo / test_feedback: 92 passed - Full backend suite: 1905 passed, 2 failed (both @requires_llm flaky integration tests unrelated to auth), 1 skipped * feat(auth): extend orphan migration to 2.0-rc persistence tables _ensure_admin_user now runs a three-step pipeline on every boot: Step 1 (fatal): admin user exists / is created / password is reset Step 2 (non-fatal): LangGraph store orphan threads → admin Step 3 (non-fatal): SQL persistence tables → admin - threads_meta - runs - run_events - feedback Each step is idempotent. The fatal/non-fatal split mirrors PR #1728's original philosophy: admin creation failure blocks startup (the system is unusable without an admin), whereas migration failures log a warning and let the service proceed (a partial migration is recoverable; a missing admin is not). Key helpers ----------- - _iter_store_items(store, namespace, *, page_size=500): async generator that cursor-paginates across LangGraph store pages. Fixes PR #1728's hardcoded limit=1000 bug that would silently lose orphans beyond the first page. - _migrate_orphaned_threads(store, admin_user_id): Rewritten to use _iter_store_items. Returns the migrated count so the caller can log it; raises only on unhandled exceptions. - _migrate_orphan_sql_tables(admin_user_id): Imports the 4 ORM models lazily, grabs the shared session factory, runs one UPDATE per table in a single transaction, commits once. No-op when no persistence backend is configured (in-memory dev). Tests: test_ensure_admin.py (8 passed) * test(auth): port AUTH test plan docs + lint/format pass - Port backend/docs/AUTH_TEST_PLAN.md and AUTH_UPGRADE.md from PR #1728 - Rename metadata.user_id → metadata.owner_id in AUTH_TEST_PLAN.md (4 occurrences from the original PR doc) - ruff auto-fix UP037 in sentinel type annotations: drop quotes around "str | None | _AutoSentinel" now that from __future__ import annotations makes them implicit string forms - ruff format: 2 files (app/gateway/app.py, runtime/user_context.py) Note on test coverage additions: - conftest.py autouse fixture was already added in commit 4 (had to be co-located with the repository changes to keep pre-existing persistence tests passing) - cross-user isolation E2E tests (test_owner_isolation.py) deferred — enforcement is already proven by the 98-test repository suite via the autouse fixture + explicit _AUTO sentinel exercises - New test cases (TC-API-17..20, TC-ATK-13, TC-MIG-01..07) listed in AUTH_TEST_PLAN.md are deferred to a follow-up PR — they are manual-QA test cases rather than pytest code, and the spec-level coverage is already met by test_user_context.py + the 98-test repository suite. Final test results: - Auth suite (test_auth*, test_langgraph_auth, test_ensure_admin, test_user_context): 186 passed - Persistence suite (test_run_event_store, test_run_repository, test_thread_meta_repo, test_feedback): 98 passed - Lint: ruff check + ruff format both clean * test(auth): add cross-user isolation test suite 10 tests exercising the storage-layer owner filter by manually switching the user_context contextvar between two users. Verifies the safety invariant: After a repository write with owner_id=A, a subsequent read with owner_id=B must not return the row, and vice versa. Covers all 4 tables that own user-scoped data: TC-API-17 threads_meta — read, search, update, delete cross-user TC-API-18 runs — get, list_by_thread, delete cross-user TC-API-19 run_events — list_messages, list_events, count_messages, delete_by_thread (CRITICAL: raw conversation content leak vector) TC-API-20 feedback — get, list_by_run, delete cross-user Plus two meta-tests verifying the sentinel pattern itself: - AUTO + unset contextvar raises RuntimeError - explicit owner_id=None bypasses the filter (migration escape hatch) Architecture note ----------------- These tests bypass the HTTP layer by design. The full chain (cookie → middleware → contextvar → repository) is covered piecewise: - test_auth_middleware.py: middleware sets contextvar from cookies - test_owner_isolation.py: repositories enforce isolation when contextvar is set to different users Together they prove the end-to-end safety property without the ceremony of spinning up a full TestClient + in-memory DB for every router endpoint. Tests pass: 231 (full auth + persistence + isolation suite) Lint: clean * refactor(auth): migrate user repository to SQLAlchemy ORM Move the users table into the shared persistence engine so auth matches the pattern of threads_meta, runs, run_events, and feedback — one engine, one session factory, one schema init codepath. New files --------- - persistence/user/__init__.py, persistence/user/model.py: UserRow ORM class with partial unique index on (oauth_provider, oauth_id) - Registered in persistence/models/__init__.py so Base.metadata.create_all() picks it up Modified -------- - auth/repositories/sqlite.py: rewritten as async SQLAlchemy, identical constructor pattern to the other four repositories (def __init__(self, session_factory) + self._sf = session_factory) - auth/config.py: drop users_db_path field — storage is configured through config.database like every other table - deps.py/get_local_provider: construct SQLiteUserRepository with the shared session factory, fail fast if engine is not initialised - tests/test_auth.py: rewrite test_sqlite_round_trip_new_fields to use the shared engine (init_engine + close_engine in a tempdir) - tests/test_auth_type_system.py: add per-test autouse fixture that spins up a scratch engine and resets deps._cached_* singletons * refactor(auth): remove SQL orphan migration (unused in supported scenarios) The _migrate_orphan_sql_tables helper existed to bind NULL owner_id rows in threads_meta, runs, run_events, and feedback to the admin on first boot. But in every supported upgrade path, it's a no-op: 1. Fresh install: create_all builds fresh tables, no legacy rows 2. No-auth → with-auth (no existing persistence DB): persistence tables are created fresh by create_all, no legacy rows 3. No-auth → with-auth (has existing persistence DB from #1930): NOT a supported upgrade path — "有 DB 到有 DB" schema evolution is out of scope; users wipe DB or run manual ALTER So the SQL orphan migration never has anything to do in the supported matrix. Delete the function, simplify _ensure_admin_user from a 3-step pipeline to a 2-step one (admin creation + LangGraph store orphan migration only). LangGraph store orphan migration stays: it serves the real "no-auth → with-auth" upgrade path where a user's existing LangGraph thread metadata has no owner_id field and needs to be stamped with the newly-created admin's id. Tests: 284 passed (auth + persistence + isolation) Lint: clean * security(auth): write initial admin password to 0600 file instead of logs CodeQL py/clear-text-logging-sensitive-data flagged 3 call sites that logged the auto-generated admin password to stdout via logger.info(). Production log aggregators (ELK/Splunk/etc) would have captured those cleartext secrets. Replace with a shared helper that writes to .deer-flow/admin_initial_credentials.txt with mode 0600, and log only the path. New file -------- - app/gateway/auth/credential_file.py: write_initial_credentials() helper. Takes email, password, and a "initial"/"reset" label. Creates .deer-flow/ if missing, writes a header comment plus the email+password, chmods 0o600, returns the absolute Path. Modified -------- - app/gateway/app.py: both _ensure_admin_user paths (fresh creation + needs_setup password reset) now write to file and log the path - app/gateway/auth/reset_admin.py: rewritten to use the shared ORM repo (SQLiteUserRepository with session_factory) and the credential_file helper. The previous implementation was broken after the earlier ORM refactor — it still imported _get_users_conn and constructed SQLiteUserRepository() without a session factory. No tests changed — the three password-log sites are all exercised via existing test_ensure_admin.py which checks that startup succeeds, not that a specific string appears in logs. CodeQL alerts 272, 283, 284: all resolved. * security(auth): strict JWT validation in middleware (fix junk cookie bypass) AUTH_TEST_PLAN test 7.5.8 expects junk cookies to be rejected with 401. The previous middleware behaviour was "presence-only": check that some access_token cookie exists, then pass through. In combination with my Task-12 decision to skip @require_auth decorators on routes, this created a gap where a request with any cookie-shaped string (e.g. access_token=not-a-jwt) would bypass authentication on routes that do not touch the repository (/api/models, /api/mcp/config, /api/memory, /api/skills, …). Fix: middleware now calls get_current_user_from_request() strictly and catches the resulting HTTPException to render a 401 with the proper fine-grained error code (token_invalid, token_expired, user_not_found, …). On success it stamps request.state.user and the contextvar so repository-layer owner filters work downstream. The 4 old "_with_cookie_passes" tests in test_auth_middleware.py were written for the presence-only behaviour; they asserted that a junk cookie would make the handler return 200. They are renamed to "_with_junk_cookie_rejected" and their assertions flipped to 401. The negative path (no cookie → 401 not_authenticated) is unchanged. Verified: no cookie → 401 not_authenticated junk cookie → 401 token_invalid (the fixed bug) expired cookie → 401 token_expired Tests: 284 passed (auth + persistence + isolation) Lint: clean * security(auth): wire @require_permission(owner_check=True) on isolation routes Apply the require_permission decorator to all 28 routes that take a {thread_id} path parameter. Combined with the strict middleware (previous commit), this gives the double-layer protection that AUTH_TEST_PLAN test 7.5.9 documents: Layer 1 (AuthMiddleware): cookie + JWT validation, rejects junk cookies and stamps request.state.user Layer 2 (@require_permission with owner_check=True): per-resource ownership verification via ThreadMetaStore.check_access — returns 404 if a different user owns the thread The decorator's owner_check branch is rewritten to use the SQL thread_meta_repo (the 2.0-rc persistence layer) instead of the LangGraph store path that PR #1728 used (_store_get / get_store in routers/threads.py). The inject_record convenience is dropped — no caller in 2.0 needs the LangGraph blob, and the SQL repo has a different shape. Routes decorated (28 total): - threads.py: delete, patch, get, get-state, post-state, post-history - thread_runs.py: post-runs, post-runs-stream, post-runs-wait, list_runs, get_run, cancel_run, join_run, stream_existing_run, list_thread_messages, list_run_messages, list_run_events, thread_token_usage - feedback.py: create, list, stats, delete - uploads.py: upload (added Request param), list, delete - artifacts.py: get_artifact - suggestions.py: generate (renamed body parameter to avoid conflict with FastAPI Request) Test fixes: - test_suggestions_router.py: bypass the decorator via __wrapped__ (the unit tests cover parsing logic, not auth — no point spinning up a thread_meta_repo just to test JSON unwrapping) - test_auth_middleware.py 4 fake-cookie tests: already updated in the previous commit (745bf432) Tests: 293 passed (auth + persistence + isolation + suggestions) Lint: clean * security(auth): defense-in-depth fixes from release validation pass Eight findings caught while running the AUTH_TEST_PLAN end-to-end against the deployed sg_dev stack. Each is a pre-condition for shipping release/2.0-rc that the previous PRs missed. Backend hardening - routers/auth.py: rate limiter X-Real-IP now requires AUTH_TRUSTED_PROXIES whitelist (CIDR/IP allowlist). Without nginx in front, the previous code honored arbitrary X-Real-IP, letting an attacker rotate the header to fully bypass the per-IP login lockout. - routers/auth.py: 36-entry common-password blocklist via Pydantic field_validator on RegisterRequest + ChangePasswordRequest. The shared _validate_strong_password helper keeps the constraint in one place. - routers/threads.py: ThreadCreateRequest + ThreadPatchRequest strip server-reserved metadata keys (owner_id, user_id) via Pydantic field_validator so a forged value can never round-trip back to other clients reading the same thread. The actual ownership invariant stays on the threads_meta row; this closes the metadata-blob echo gap. - authz.py + thread_meta/sql.py: require_permission gains a require_existing flag plumbed through check_access(require_existing=True). Destructive routes (DELETE/PATCH/state-update/runs/feedback) now treat a missing thread_meta row as 404 instead of "untracked legacy thread, allow", closing the cross-user delete-idempotence gap where any user could successfully DELETE another user's deleted thread. - repositories/sqlite.py + base.py: update_user raises UserNotFoundError on a vanished row instead of silently returning the input. Concurrent delete during password reset can no longer look like a successful update. - runtime/user_context.py: resolve_owner_id() coerces User.id (UUID) to str at the contextvar boundary so SQLAlchemy String(64) columns can bind it. The whole 2.0-rc isolation pipeline was previously broken end-to-end (POST /api/threads → 500 "type 'UUID' is not supported"). - persistence/engine.py: SQLAlchemy listener enables PRAGMA journal_mode=WAL, synchronous=NORMAL, foreign_keys=ON on every new SQLite connection. TC-UPG-06 in the test plan expects WAL; previous code shipped with the default 'delete' journal. - auth_middleware.py: stamp request.state.auth = AuthContext(...) so @require_permission's short-circuit fires; previously every isolation request did a duplicate JWT decode + users SELECT. Also unifies the 401 payload through AuthErrorResponse(...).model_dump(). - app.py: _ensure_admin_user restructure removes the noqa F821 scoping bug where 'password' was referenced outside the branch that defined it. New _announce_credentials helper absorbs the duplicate log block in the fresh-admin and reset-admin branches. * fix(frontend+nginx): rollout CSRF on every state-changing client path The frontend was 100% broken in gateway-pro mode for any user trying to open a specific chat thread. Three cumulative bugs each silently masked the next. LangGraph SDK CSRF gap (api-client.ts) - The Client constructor took only apiUrl, no defaultHeaders, no fetch interceptor. The SDK's internal fetch never sent X-CSRF-Token, so every state-changing /api/langgraph-compat/* call (runs/stream, threads/search, threads/{tid}/history, ...) hit CSRFMiddleware and got 403 before reaching the auth check. UI symptom: empty thread page with no error message; the SPA's hooks swallowed the rejection. - Fix: pass an onRequest hook that injects X-CSRF-Token from the csrf_token cookie per request. Reading the cookie per call (not at construction time) handles login / logout / password-change cookie rotation transparently. The SDK's prepareFetchOptions calls onRequest for both regular requests AND streaming/SSE/reconnect, so the same hook covers runs.stream and runs.joinStream. Raw fetch CSRF gap (7 files) - Audit: 11 frontend fetch sites, only 2 included CSRF (login/setup + account-settings change-password). The other 7 routed through raw fetch() with no header — suggestions, memory, agents, mcp, skills, uploads, and the local thread cleanup hook all 403'd silently. - Fix: enhance fetcher.ts:fetchWithAuth to auto-inject X-CSRF-Token on POST/PUT/DELETE/PATCH from a single shared readCsrfCookie() helper. Convert all 7 raw fetch() callers to fetchWithAuth so the contract is centrally enforced. api-client.ts and fetcher.ts share readCsrfCookie + STATE_CHANGING_METHODS to avoid drift. nginx routing + buffering (nginx.local.conf) - The auth feature shipped without updating the nginx config: per-API explicit location blocks but no /api/v1/auth/, /api/feedback, /api/runs. The frontend's client-side fetches to /api/v1/auth/login/local 404'd from the Next.js side because nginx routed /api/* to the frontend. - Fix: add catch-all `location /api/` that proxies to the gateway. nginx longest-prefix matching keeps the explicit blocks (/api/models, /api/threads regex, /api/langgraph/, ...) winning for their paths. - Fix: disable proxy_buffering + proxy_request_buffering for the frontend `location /` block. Without it, nginx tries to spool large Next.js chunks into /var/lib/nginx/proxy (root-owned) and fails with Permission denied → ERR_INCOMPLETE_CHUNKED_ENCODING → ChunkLoadError. * test(auth): release-validation test infra and new coverage Test fixtures and unit tests added during the validation pass. Router test helpers (NEW: tests/_router_auth_helpers.py) - make_authed_test_app(): builds a FastAPI test app with a stub middleware that stamps request.state.user + request.state.auth and a permissive thread_meta_repo mock. TestClient-based router tests (test_artifacts_router, test_threads_router) use it instead of bare FastAPI() so the new @require_permission(owner_check=True) decorators short-circuit cleanly. - call_unwrapped(): walks the __wrapped__ chain to invoke the underlying handler without going through the authz wrappers. Direct-call tests (test_uploads_router) use it. Typed with ParamSpec so the wrapped signature flows through. Backend test additions - test_auth.py: 7 tests for the new _get_client_ip trust model (no proxy / trusted proxy / untrusted peer / XFF rejection / invalid CIDR / no client). 5 tests for the password blocklist (literal, case-insensitive, strong password accepted, change-password binding, short-password length-check still fires before blocklist). test_update_user_raises_when_row_concurrently_deleted: closes a shipped-without-coverage gap on the new UserNotFoundError contract. - test_thread_meta_repo.py: 4 tests for check_access(require_existing=True) — strict missing-row denial, strict owner match, strict owner mismatch, strict null-owner still allowed (shared rows survive the tightening). - test_ensure_admin.py: 3 tests for _migrate_orphaned_threads / _iter_store_items pagination, covering the TC-UPG-02 upgrade story end-to-end via mock store. Closes the gap where the cursor pagination was untested even though the previous PR rewrote it. - test_threads_router.py: 5 tests for _strip_reserved_metadata (owner_id removal, user_id removal, safe-keys passthrough, empty input, both-stripped). - test_auth_type_system.py: replace "password123" fixtures with Tr0ub4dor3a / AnotherStr0ngPwd! so the new password blocklist doesn't reject the test data. * docs(auth): refresh TC-DOCKER-05 + document Docker validation gap - AUTH_TEST_PLAN.md TC-DOCKER-05: the previous expectation ("admin password visible in docker logs") was stale after the simplify pass that moved credentials to a 0600 file. The grep "Password:" check would have silently failed and given a false sense of coverage. New expectation matches the actual file-based path: 0600 file in DEER_FLOW_HOME, log shows the path (not the secret), reverse-grep asserts no leaked password in container logs. - NEW: docs/AUTH_TEST_DOCKER_GAP.md documents the only un-executed block in the test plan (TC-DOCKER-01..06). Reason: sg_dev validation host has no Docker daemon installed. The doc maps each Docker case to an already-validated bare-metal equivalent (TC-1.1, TC-REENT-01, TC-API-02 etc.) so the gap is auditable, and includes pre-flight reproduction steps for whoever has Docker available. --------- Co-authored-by: greatmengqi <chenmengqi.0376@bytedance.com>	2026-04-26 11:08:11 +08:00
rayhpeng	d8ecaf46c9	feat(persistence): add unified persistence layer with event store, token tracking, and feedback (#1930) ... * feat(persistence): add SQLAlchemy 2.0 async ORM scaffold Introduce a unified database configuration (DatabaseConfig) that controls both the LangGraph checkpointer and the DeerFlow application persistence layer from a single `database:` config section. New modules: - deerflow.config.database_config — Pydantic config with memory/sqlite/postgres backends - deerflow.persistence — async engine lifecycle, DeclarativeBase with to_dict mixin, Alembic skeleton - deerflow.runtime.runs.store — RunStore ABC + MemoryRunStore implementation Gateway integration initializes/tears down the persistence engine in the existing langgraph_runtime() context manager. Legacy checkpointer config is preserved for backward compatibility. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(persistence): add RunEventStore ABC + MemoryRunEventStore Phase 2-A prerequisite for event storage: adds the unified run event stream interface (RunEventStore) with an in-memory implementation, RunEventsConfig, gateway integration, and comprehensive tests (27 cases). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(persistence): add ORM models, repositories, DB/JSONL event stores, RunJournal, and API endpoints Phase 2-B: run persistence + event storage + token tracking. - ORM models: RunRow (with token fields), ThreadMetaRow, RunEventRow - RunRepository implements RunStore ABC via SQLAlchemy ORM - ThreadMetaRepository with owner access control - DbRunEventStore with trace content truncation and cursor pagination - JsonlRunEventStore with per-run files and seq recovery from disk - RunJournal (BaseCallbackHandler) captures LLM/tool/lifecycle events, accumulates token usage by caller type, buffers and flushes to store - RunManager now accepts optional RunStore for persistent backing - Worker creates RunJournal, writes human_message, injects callbacks - Gateway deps use factory functions (RunRepository when DB available) - New endpoints: messages, run messages, run events, token-usage - ThreadCreateRequest gains assistant_id field - 92 tests pass (33 new), zero regressions Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(persistence): add user feedback + follow-up run association Phase 2-C: feedback and follow-up tracking. - FeedbackRow ORM model (rating +1/-1, optional message_id, comment) - FeedbackRepository with CRUD, list_by_run/thread, aggregate stats - Feedback API endpoints: create, list, stats, delete - follow_up_to_run_id in RunCreateRequest (explicit or auto-detected from latest successful run on the thread) - Worker writes follow_up_to_run_id into human_message event metadata - Gateway deps: feedback_repo factory + getter - 17 new tests (14 FeedbackRepository + 3 follow-up association) - 109 total tests pass, zero regressions Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * test+config: comprehensive Phase 2 test coverage + deprecate checkpointer config - config.example.yaml: deprecate standalone checkpointer section, activate unified database:sqlite as default (drives both checkpointer + app data) - New: test_thread_meta_repo.py (14 tests) — full ThreadMetaRepository coverage including check_access owner logic, list_by_owner pagination - Extended test_run_repository.py (+4 tests) — completion preserves fields, list ordering desc, limit, owner_none returns all - Extended test_run_journal.py (+8 tests) — on_chain_error, track_tokens=false, middleware no ai_message, unknown caller tokens, convenience fields, tool_error, non-summarization custom event - Extended test_run_event_store.py (+7 tests) — DB batch seq continuity, make_run_event_store factory (memory/db/jsonl/fallback/unknown) - Extended test_phase2b_integration.py (+4 tests) — create_or_reject persists, follow-up metadata, summarization in history, full DB-backed lifecycle - Fixed DB integration test to use proper fake objects (not MagicMock) for JSON-serializable metadata - 157 total Phase 2 tests pass, zero regressions Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * config: move default sqlite_dir to .deer-flow/data Keep SQLite databases alongside other DeerFlow-managed data (threads, memory) under the .deer-flow/ directory instead of a top-level ./data folder. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * refactor(persistence): remove UTFJSON, use engine-level json_serializer + datetime.now() - Replace custom UTFJSON type with standard sqlalchemy.JSON in all ORM models. Add json_serializer=json.dumps(ensure_ascii=False) to all create_async_engine calls so non-ASCII text (Chinese etc.) is stored as-is in both SQLite and Postgres. - Change ORM datetime defaults from datetime.now(UTC) to datetime.now(), remove UTC imports. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * refactor(gateway): simplify deps.py with getter factory + inline repos - Replace 6 identical getter functions with _require() factory. - Inline 3 _make_*_repo() factories into langgraph_runtime(), call get_session_factory() once instead of 3 times. - Add thread_meta upsert in start_run (services.py). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(docker): add UV_EXTRAS build arg for optional dependencies Support installing optional dependency groups (e.g. postgres) at Docker build time via UV_EXTRAS build arg: UV_EXTRAS=postgres docker compose build Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * refactor(journal): fix flush, token tracking, and consolidate tests RunJournal fixes: - _flush_sync: retain events in buffer when no event loop instead of dropping them; worker's finally block flushes via async flush(). - on_llm_end: add tool_calls filter and caller=="lead_agent" guard for ai_message events; mark message IDs for dedup with record_llm_usage. - worker.py: persist completion data (tokens, message count) to RunStore in finally block. Model factory: - Auto-inject stream_usage=True for BaseChatOpenAI subclasses with custom api_base, so usage_metadata is populated in streaming responses. Test consolidation: - Delete test_phase2b_integration.py (redundant with existing tests). - Move DB-backed lifecycle test into test_run_journal.py. - Add tests for stream_usage injection in test_model_factory.py. - Clean up executor/task_tool dead journal references. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(events): widen content type to str|dict in all store backends Allow event content to be a dict (for structured OpenAI-format messages) in addition to plain strings. Dict values are JSON-serialized for the DB backend and deserialized on read; memory and JSONL backends handle dicts natively. Trace truncation now serializes dicts to JSON before measuring. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(events): use metadata flag instead of heuristic for dict content detection Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(converters): add LangChain-to-OpenAI message format converters Pure functions langchain_to_openai_message, langchain_to_openai_completion, langchain_messages_to_openai, and _infer_finish_reason for converting LangChain BaseMessage objects to OpenAI Chat Completions format, used by RunJournal for event storage. 15 unit tests added. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(converters): handle empty list content as null, clean up test Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(events): human_message content uses OpenAI user message format Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * feat(events): ai_message uses OpenAI format, add ai_tool_call message event - ai_message content now uses {"role": "assistant", "content": "..."} format - New ai_tool_call message event emitted when lead_agent LLM responds with tool_calls - ai_tool_call uses langchain_to_openai_message converter for consistent format - Both events include finish_reason in metadata ("stop" or "tool_calls") Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(events): add tool_result message event with OpenAI tool message format Cache tool_call_id from on_tool_start keyed by run_id as fallback for on_tool_end, then emit a tool_result message event (role=tool, tool_call_id, content) after each successful tool completion. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * feat(events): summary content uses OpenAI system message format Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(events): replace llm_start/llm_end with llm_request/llm_response in OpenAI format Add on_chat_model_start to capture structured prompt messages as llm_request events. Replace llm_end trace events with llm_response using OpenAI Chat Completions format. Track llm_call_index to pair request/response events. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(events): add record_middleware method for middleware trace events Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * test(events): add full run sequence integration test for OpenAI content format Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * feat(events): align message events with checkpoint format and add middleware tag injection - Message events (ai_message, ai_tool_call, tool_result, human_message) now use BaseMessage.model_dump() format, matching LangGraph checkpoint values.messages - on_tool_end extracts tool_call_id/name/status from ToolMessage objects - on_tool_error now emits tool_result message events with error status - record_middleware uses middleware:{tag} event_type and middleware category - Summarization custom events use middleware:summarize category - TitleMiddleware injects middleware:title tag via get_config() inheritance - SummarizationMiddleware model bound with middleware:summarize tag - Worker writes human_message using HumanMessage.model_dump() Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(threads): switch search endpoint to threads_meta table and sync title - POST /api/threads/search now queries threads_meta table directly, removing the two-phase Store + Checkpointer scan approach - Add ThreadMetaRepository.search() with metadata/status filters - Add ThreadMetaRepository.update_display_name() for title sync - Worker syncs checkpoint title to threads_meta.display_name on run completion - Map display_name to values.title in search response for API compatibility Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(threads): history endpoint reads messages from event store - POST /api/threads/{thread_id}/history now combines two data sources: checkpointer for checkpoint_id, metadata, title, thread_data; event store for messages (complete history, not truncated by summarization) - Strip internal LangGraph metadata keys from response - Remove full channel_values serialization in favor of selective fields Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: remove duplicate optional-dependencies header in pyproject.toml Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(middleware): pass tagged config to TitleMiddleware ainvoke call Without the config, the middleware:title tag was not injected, causing the LLM response to be recorded as a lead_agent ai_message in run_events. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: resolve merge conflict in .env.example Keep both DATABASE_URL (from persistence-scaffold) and WECOM credentials (from main) after the merge. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(persistence): address review feedback on PR #1851 - Fix naive datetime.now() → datetime.now(UTC) in all ORM models - Fix seq race condition in DbRunEventStore.put() with FOR UPDATE and UNIQUE(thread_id, seq) constraint - Encapsulate _store access in RunManager.update_run_completion() - Deduplicate _store.put() logic in RunManager via _persist_to_store() - Add update_run_completion to RunStore ABC + MemoryRunStore - Wire follow_up_to_run_id through the full create path - Add error recovery to RunJournal._flush_sync() lost-event scenario - Add migration note for search_threads breaking change - Fix test_checkpointer_none_fix mock to set database=None Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * chore: update uv.lock Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(persistence): address 22 review comments from CodeQL, Copilot, and Code Quality Bug fixes: - Sanitize log params to prevent log injection (CodeQL) - Reset threads_meta.status to idle/error when run completes - Attach messages only to latest checkpoint in /history response - Write threads_meta on POST /threads so new threads appear in search Lint fixes: - Remove unused imports (journal.py, migrations/env.py, test_converters.py) - Convert lambda to named function (engine.py, Ruff E731) - Remove unused logger definitions in repos (Ruff F841) - Add logging to JSONL decode errors and empty except blocks - Separate assert side-effects in tests (CodeQL) - Remove unused local variables in tests (Ruff F841) - Fix max_trace_content truncation to use byte length, not char length Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * style: apply ruff format to persistence and runtime files Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * Potential fix for pull request finding 'Statement has no effect' Co-authored-by: Copilot Autofix powered by AI <223894421+github-code-quality[bot]@users.noreply.github.com> * refactor(runtime): introduce RunContext to reduce run_agent parameter bloat Extract checkpointer, store, event_store, run_events_config, thread_meta_repo, and follow_up_to_run_id into a frozen RunContext dataclass. Add get_run_context() in deps.py to build the base context from app.state singletons. start_run() uses dataclasses.replace() to enrich per-run fields before passing ctx to run_agent. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * refactor(gateway): move sanitize_log_param to app/gateway/utils.py Extract the log-injection sanitizer from routers/threads.py into a shared utils module and rename to sanitize_log_param (public API). Eliminates the reverse service → router import in services.py. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * perf: use SQL aggregation for feedback stats and thread token usage Replace Python-side counting in FeedbackRepository.aggregate_by_run with a single SELECT COUNT/SUM query. Add RunStore.aggregate_tokens_by_thread abstract method with SQL GROUP BY implementation in RunRepository and Python fallback in MemoryRunStore. Simplify the thread_token_usage endpoint to delegate to the new method, eliminating the limit=10000 truncation risk. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * docs: annotate DbRunEventStore.put() as low-frequency path Add docstring clarifying that put() opens a per-call transaction with FOR UPDATE and should only be used for infrequent writes (currently just the initial human_message event). High-throughput callers should use put_batch() instead. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(threads): fall back to Store search when ThreadMetaRepository is unavailable When database.backend=memory (default) or no SQL session factory is configured, search_threads now queries the LangGraph Store instead of returning 503. Returns empty list if neither Store nor repo is available. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * refactor(persistence): introduce ThreadMetaStore ABC for backend-agnostic thread metadata Add ThreadMetaStore abstract base class with create/get/search/update/delete interface. ThreadMetaRepository (SQL) now inherits from it. New MemoryThreadMetaStore wraps LangGraph BaseStore for memory-mode deployments. deps.py now always provides a non-None thread_meta_repo, eliminating all `if thread_meta_repo is not None` guards in services.py, worker.py, and routers/threads.py. search_threads no longer needs a Store fallback branch. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * refactor(history): read messages from checkpointer instead of RunEventStore The /history endpoint now reads messages directly from the checkpointer's channel_values (the authoritative source) instead of querying RunEventStore.list_messages(). The RunEventStore API is preserved for other consumers. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(persistence): address new Copilot review comments - feedback.py: validate thread_id/run_id before deleting feedback - jsonl.py: add path traversal protection with ID validation - run_repo.py: parse `before` to datetime for PostgreSQL compat - thread_meta_repo.py: fix pagination when metadata filter is active - database_config.py: use resolve_path for sqlite_dir consistency Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * Implement skill self-evolution and skill_manage flow (#1874) * chore: ignore .worktrees directory * Add skill_manage self-evolution flow * Fix CI regressions for skill_manage * Address PR review feedback for skill evolution * fix(skill-evolution): preserve history on delete * fix(skill-evolution): tighten scanner fallbacks * docs: add skill_manage e2e evidence screenshot * fix(skill-manage): avoid blocking fs ops in session runtime --------- Co-authored-by: Willem Jiang <willem.jiang@gmail.com> * fix(config): resolve sqlite_dir relative to CWD, not Paths.base_dir resolve_path() resolves relative to Paths.base_dir (.deer-flow), which double-nested the path to .deer-flow/.deer-flow/data/app.db. Use Path.resolve() (CWD-relative) instead. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * Feature/feishu receive file (#1608) * feat(feishu): add channel file materialization hook for inbound messages - Introduce Channel.receive_file(msg, thread_id) as a base method for file materialization; default is no-op. - Implement FeishuChannel.receive_file to download files/images from Feishu messages, save to sandbox, and inject virtual paths into msg.text. - Update ChannelManager to call receive_file for any channel if msg.files is present, enabling downstream model access to user-uploaded files. - No impact on Slack/Telegram or other channels (they inherit the default no-op). * style(backend): format code with ruff for lint compliance - Auto-formatted packages/harness/deerflow/agents/factory.py and tests/test_create_deerflow_agent.py using `ruff format` - Ensured both files conform to project linting standards - Fixes CI lint check failures caused by code style issues * fix(feishu): handle file write operation asynchronously to prevent blocking * fix(feishu): rename GetMessageResourceRequest to _GetMessageResourceRequest and remove redundant code * test(feishu): add tests for receive_file method and placeholder replacement * fix(manager): remove unnecessary type casting for channel retrieval * fix(feishu): update logging messages to reflect resource handling instead of image * fix(feishu): sanitize filename by replacing invalid characters in file uploads * fix(feishu): improve filename sanitization and reorder image key handling in message processing * fix(feishu): add thread lock to prevent filename conflicts during file downloads * fix(test): correct bad merge in test_feishu_parser.py * chore: run ruff and apply formatting cleanup fix(feishu): preserve rich-text attachment order and improve fallback filename handling * fix(docker): restore gateway env vars and fix langgraph empty arg issue (#1915) Two production docker-compose.yaml bugs prevent `make up` from working: 1. Gateway missing DEER_FLOW_CONFIG_PATH and DEER_FLOW_EXTENSIONS_CONFIG_PATH environment overrides. Added in fb2d99f (#1836) but accidentally reverted by ca2fb95 (#1847). Without them, gateway reads host paths from .env via env_file, causing FileNotFoundError inside the container. 2. Langgraph command fails when LANGGRAPH_ALLOW_BLOCKING is unset (default). Empty $${allow_blocking} inserts a bare space between flags, causing ' --no-reload' to be parsed as unexpected extra argument. Fix by building args string first and conditionally appending --allow-blocking. Co-authored-by: cooper <cooperfu@tencent.com> * fix(frontend): resolve invalid HTML nesting and tabnabbing vulnerabilities (#1904) * fix(frontend): resolve invalid HTML nesting and tabnabbing vulnerabilities Fix `<button>` inside `<a>` invalid HTML in artifact components and add missing `noopener,noreferrer` to `window.open` calls to prevent reverse tabnabbing. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix(frontend): address Copilot review on tabnabbing and double-tab-open Remove redundant parent onClick on web_fetch ChainOfThoughtStep to prevent opening two tabs on link click, and explicitly null out window.opener after window.open() for defensive tabnabbing hardening. --------- Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com> * refactor(persistence): organize entities into per-entity directories Restructure the persistence layer from horizontal "models/ + repositories/" split into vertical entity-aligned directories. Each entity (thread_meta, run, feedback) now owns its ORM model, abstract interface (where applicable), and concrete implementations under a single directory with an aggregating __init__.py for one-line imports. Layout: persistence/thread_meta/{base,model,sql,memory}.py persistence/run/{model,sql}.py persistence/feedback/{model,sql}.py models/__init__.py is kept as a facade so Alembic autogenerate continues to discover all ORM tables via Base.metadata. RunEventRow remains under models/run_event.py because its storage implementation lives in runtime/events/store/db.py and has no matching repository directory. The repositories/ directory is removed entirely. All call sites in gateway/deps.py and tests are updated to import from the new entity packages, e.g.: from deerflow.persistence.thread_meta import ThreadMetaRepository from deerflow.persistence.run import RunRepository from deerflow.persistence.feedback import FeedbackRepository Full test suite passes (1690 passed, 14 skipped). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(gateway): sync thread rename and delete through ThreadMetaStore The POST /threads/{id}/state endpoint previously synced title changes only to the LangGraph Store via _store_upsert. In sqlite mode the search endpoint reads from the ThreadMetaRepository SQL table, so renames never appeared in /threads/search until the next agent run completed (worker.py syncs title from checkpoint to thread_meta in its finally block). Likewise the DELETE /threads/{id} endpoint cleaned up the filesystem, Store, and checkpointer but left the threads_meta row orphaned in sqlite, so deleted threads kept appearing in /threads/search. Fix both endpoints by routing through the ThreadMetaStore abstraction which already has the correct sqlite/memory implementations wired up by deps.py. The rename path now calls update_display_name() and the delete path calls delete() — both work uniformly across backends. Verified end-to-end with curl in gateway mode against sqlite backend. Existing test suite (1690 passed) and focused router/repo tests pass. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * refactor(gateway): route all thread metadata access through ThreadMetaStore Following the rename/delete bug fix in PR1, migrate the remaining direct LangGraph Store reads/writes in the threads router and services to the ThreadMetaStore abstraction so that the sqlite and memory backends behave identically and the legacy dual-write paths can be removed. Migrated endpoints (threads.py): - create_thread: idempotency check + write now use thread_meta_repo.get/create instead of dual-writing the LangGraph Store and the SQL row. - get_thread: reads from thread_meta_repo.get; the checkpoint-only fallback for legacy threads is preserved. - patch_thread: replaced _store_get/_store_put with thread_meta_repo.update_metadata. - delete_thread_data: dropped the legacy store.adelete; thread_meta_repo.delete already covers it. Removed dead code (services.py): - _upsert_thread_in_store — redundant with the immediately following thread_meta_repo.create() call. - _sync_thread_title_after_run — worker.py's finally block already syncs the title via thread_meta_repo.update_display_name() after each run. Removed dead code (threads.py): - _store_get / _store_put / _store_upsert helpers (no remaining callers). - THREADS_NS constant. - get_store import (router no longer touches the LangGraph Store directly). New abstract method: - ThreadMetaStore.update_metadata(thread_id, metadata) merges metadata into the thread's metadata field. Implemented in both ThreadMetaRepository (SQL, read-modify-write inside one session) and MemoryThreadMetaStore. Three new unit tests cover merge / empty / nonexistent behaviour. Net change: -134 lines. Full test suite: 1693 passed, 14 skipped. Verified end-to-end with curl in gateway mode against sqlite backend (create / patch / get / rename / search / delete).

rayhpeng	34e835bc33	feat(gateway): implement LangGraph Platform API in Gateway, replace langgraph-cli (#1403) ... * feat(gateway): implement LangGraph Platform API in Gateway, replace langgraph-cli Implement all core LangGraph Platform API endpoints in the Gateway, allowing it to fully replace the langgraph-cli dev server for local development. This eliminates a heavyweight dependency and simplifies the development stack. Changes: - Add runs lifecycle endpoints (create, stream, wait, cancel, join) - Add threads CRUD and search endpoints - Add assistants compatibility endpoints (search, get, graph, schemas) - Add StreamBridge (in-memory pub/sub for SSE) and async provider - Add RunManager with atomic create_or_reject (eliminates TOCTOU race) - Add worker with interrupt/rollback cancel actions and runtime context injection - Route /api/langgraph/* to Gateway in nginx config - Skip langgraph-cli startup by default (SKIP_LANGGRAPH_SERVER=0 to restore) - Add unit tests for RunManager, SSE format, and StreamBridge * fix: drain bridge queue on client disconnect to prevent backpressure When on_disconnect=continue, keep consuming events from the bridge without yielding, so the worker is not blocked by a full queue. Only on_disconnect=cancel breaks out immediately.

Router modules will delegate to these functions instead of using private cross-imported helpers. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * refactor: wire routers to use services layer, remove cross-module private imports Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * style: apply ruff formatting to refactored files Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(runtime): support LangGraph dev server and add compat route - Enable official LangGraph dev server for local development workflow - Decouple runtime components from agents package for better separation - Provide gateway-backed fallback route when dev server is skipped - Simplify lifecycle management using context manager in gateway * feat(runtime): add Store providers with auto-backend selection - Add async_provider.py and provider.py under deerflow/runtime/store/ - Support memory, sqlite, postgres backends matching checkpointer config - Integrate into FastAPI lifespan via AsyncExitStack in deps.py - Replace hardcoded InMemoryStore with config-driven factory * refactor(gateway): migrate thread management from checkpointer to Store and resolve multiple endpoint failures - Add Store-backed CRUD helpers (_store_get, _store_put, _store_upsert) - Replace checkpoint-scanning search with two-phase strategy: phase 1 reads Store (O(threads)), phase 2 backfills from checkpointer for legacy/LangGraph Server threads with lazy migration - Extend Store record schema with values field for title persistence - Sync thread title from checkpoint to Store after run completion - Fix /threads/{id}/runs/{run_id}/stream 405 by accepting both GET and POST methods; POST handles interrupt/rollback actions - Fix /threads/{id}/state 500 by separating read_config and write_config, adding checkpoint_ns to configurable, and shallow-copying checkpoint/metadata before mutation - Sync title to Store on state update for immediate search reflection - Move _upsert_thread_in_store into services.py, remove duplicate logic - Add _sync_thread_title_after_run: await run task, read final checkpoint title, write back to Store record - Spawn title sync as background task from start_run when Store exists * refactor(runtime): deduplicate store and checkpointer provider logic Extract _ensure_sqlite_parent_dir() helper into checkpointer/provider.py and use it in all three places that previously inlined the same mkdir logic. Consolidate duplicate error constants in store/async_provider.py by importing from store/provider.py instead of redefining them. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * refactor(runtime): move SQLite helpers to runtime/store, checkpointer imports from store _resolve_sqlite_conn_str and _ensure_sqlite_parent_dir now live in runtime/store/provider.py. agents/checkpointer/provider and agents/checkpointer/async_provider import from there, reversing the previous dependency direction (store → checkpointer becomes checkpointer → store). Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * refactor(runtime): extract SQLite helpers into runtime/store/_sqlite_utils.py Move resolve_sqlite_conn_str and ensure_sqlite_parent_dir out of checkpointer/provider.py into a dedicated _sqlite_utils module. Functions are now public (no underscore prefix), making cross-module imports semantically correct. All four provider files import from the single shared location. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(gateway): use adelete_thread to fully remove thread checkpoints on delete AsyncSqliteSaver has no adelete method — the previous hasattr check always evaluated to False, silently leaving all checkpoint rows in the database. Switch to adelete_thread(thread_id) which deletes every checkpoint and pending-write row for the thread across all namespaces (including sub-graph checkpoints). Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(gateway): remove dead bridge_cm/ckpt_cm code and fix StrEnum lint app.py had unreachable code after the async-with lifespan refactor: bridge_cm and ckpt_cm were referenced but never defined (F821), and the channel service startup/shutdown was outside the langgraph_runtime block so it never ran. Move channel service lifecycle inside the async-with block where it belongs. Replace str+Enum inheritance in RunStatus and DisconnectMode with StrEnum as suggested by UP042.
