fix(knowledge_sql): match write keywords on word boundaries (allow valid SELECTs) (#640 )

* fix(knowledge_sql): match write keywords on word boundaries The read-only guard rejected a query if any of DROP/DELETE/INSERT/UPDATE/ ALTER/CREATE/ATTACH appeared as a bare substring of the uppercased text. That wrongly blocks valid SELECTs whose column/alias/literal merely contains one -- e.g. "deleted_at" (DELETE), "created_at" (CREATE), "updated_content" (UPDATE). The knowledge_chunks table actually has deleted_at/created_at columns and the store's own retrieval filters on "WHERE deleted_at IS NULL", so realistic read queries were refused. Match on word boundaries with a compiled regex, mirroring the sibling tool db_query.py. Add a regression test. * fix(knowledge_sql): ignore string literals in keyword scan, broaden error handling - Strip single-quoted literals before the forbidden-keyword scan so SELECTs whose data merely mentions a write keyword (e.g. LIKE '%delete%') are not rejected. - Catch sqlite3.Error instead of only OperationalError so multi- statement strings return a failed ToolResult instead of raising. - Document created_at/deleted_at in the tool's schema description. --------- Co-authored-by: Elliot Slusky <elliot@slusky.com>

Syed Osama Ali ShahandElliot Slusky	23f04264f9	fix(knowledge_sql): match write keywords on word boundaries (allow valid SELECTs) (#640 ) * fix(knowledge_sql): match write keywords on word boundaries The read-only guard rejected a query if any of DROP/DELETE/INSERT/UPDATE/ ALTER/CREATE/ATTACH appeared as a bare substring of the uppercased text. That wrongly blocks valid SELECTs whose column/alias/literal merely contains one -- e.g. "deleted_at" (DELETE), "created_at" (CREATE), "updated_content" (UPDATE). The knowledge_chunks table actually has deleted_at/created_at columns and the store's own retrieval filters on "WHERE deleted_at IS NULL", so realistic read queries were refused. Match on word boundaries with a compiled regex, mirroring the sibling tool db_query.py. Add a regression test. * fix(knowledge_sql): ignore string literals in keyword scan, broaden error handling - Strip single-quoted literals before the forbidden-keyword scan so SELECTs whose data merely mentions a write keyword (e.g. LIKE '%delete%') are not rejected. - Catch sqlite3.Error instead of only OperationalError so multi- statement strings return a failed ToolResult instead of raising. - Document created_at/deleted_at in the tool's schema description. --------- Co-authored-by: Elliot Slusky <elliot@slusky.com>	2026-07-16 16:36:31 -07:00

Jon Saad-FalconandClaude Opus 4.8	6240c59ca3	Update cost-comparison models: GPT-5.6 Sol, Claude Fable 5 (#634 ) Refresh the cost-comparison / savings surfaces to current frontier cloud pricing (per 1M tokens): - OpenAI: GPT-5.3 ($2/$10) -> GPT-5.6 Sol ($5/$30) - Anthropic: Claude Opus 4.6 ($5/$25) -> Claude Fable 5 ($10/$50) - Google: Gemini 3.1 Pro ($2/$12) -> unchanged Internal provider keys are renamed in lockstep (gpt-5.3 -> gpt-5.6-sol, claude-opus-4.6 -> claude-fable-5) across the canonical CLOUD_PRICING dict, the two server-rendered HTML pages, and the frontend color/label maps so backend, dashboard, and UI stay consistent. Energy/FLOPs metadata is carried over unchanged. Model catalog and eval configs are untouched (real model/benchmark entries, not the cost comparison).

talyaseenandClaude Opus 4.8	0b140110d8	Make OpenAI-compat and Ollama engine streaming truly async (#626 ) The OpenAI-compat and Ollama engines exposed stream()/stream_full() as async def but iterated a synchronous httpx.Client.iter_lines() internally, blocking the single event loop on every inter-token read (serializing concurrent chats; one wedged upstream read froze the whole API). Convert both to a shared AsyncHTTPEngineMixin using httpx.AsyncClient + aiter_lines() with a per-event-loop pooled client and the configured timeout applied; map mid-stream transport errors (RemoteProtocolError/ReadError) to EngineConnectionError via a deliberately narrow set that keeps CancelledError/GeneratorExit propagating; handle non-2xx explicitly (incl. 3xx and a typed EngineContextLengthError for context-window overflow 400s); switch litellm streaming to acompletion; and offload the blocking non-streaming handlers and websocket generate() to asyncio.to_thread. No public API change. Strong MockTransport-based tests, including a pin that the async path never touches the sync client. Complements #618.

Elliot SluskyandClaude Opus 4.8	928776a71c	ci: enforce ruff format in CI, add Makefile matching the CI test lane (#625 ) CI's lint job ran ruff check but never ruff format --check, letting format drift land silently (79 files had drifted from the pinned ruff 0.15.1). Add the ruff format --check step to ci.yml, reformat the 79 drifted files with the pinned ruff (mechanical only — verified AST-identical to before across all files, no logic changes), and add a Makefile whose test target mirrors the actual CI lane.

Jon Saad-Falcon Claude Opus 4.8 Elliot Slusky	26bc7efb09	fix(packaging): make openjarvis-rust a uv-only group to unblock pip install openjarvis[desktop] (#624 ) * fix(packaging): make openjarvis-rust a uv-only dependency group (unblock pip[desktop]) #615 added openjarvis-rust to the published `desktop` extra so `uv sync --extra desktop` builds the native PyO3 extension for the desktop app. But openjarvis-rust is not on PyPI and `[tool.uv.sources]` is stripped from published wheel metadata, so `pip install openjarvis[desktop]` from PyPI failed at install trying to resolve openjarvis-rust from PyPI (#584). Move openjarvis-rust into a uv `desktop-native` dependency group (PEP 735 — excluded from wheel metadata) and sync it in the desktop app via `uv sync --group desktop-native`. The extension is still built from the local path source; only the published metadata changes. Verified: the built wheel no longer lists openjarvis-rust in any Requires-Dist (nowhere in the metadata), and uv.lock still resolves it from the local path source under the group. Adds tests/deployment/test_packaging.py to guard the split (not in the published extra, present in the group, path source, and the desktop app syncs the group).

Elliot SluskyandClaude Opus 4.8	d865b4bed4	Fix blocking async server handlers (#618 ) Closes #219. Replace synchronous httpx calls in async SendBlue and model-management handlers with awaited httpx.AsyncClient (context-managed close); run Whisper transcription and engine.list_models via asyncio.to_thread so they don't block the event loop; and harden TelemetryStore/aggregator SQLite for concurrency (WAL, synchronous=NORMAL, busy_timeout=5000, plus a write-serializing lock on the shared connection). Adds async-usage assertions and a real 8-thread concurrent-write test. Related: #570 (async httpx, different issue #559).
