From 49cdd751ec22a0e5b107416c50ba6328f750da7e Mon Sep 17 00:00:00 2001 From: Lyonzin Date: Thu, 3 Sep 2026 22:20:13 -0300 Subject: [PATCH 1/5] fix(config): resolve relative and tilde KNOWLEDGE_RAG_DIR at startup Apply .expanduser().resolve() to BASE_DIR so relative paths (./data) and tilde paths (~/rag) produce absolute derived paths. Idempotent for existing absolute paths. Cross-platform safe.

In HTTP/SSE mode the Chroma Rust binding holds a live sqlx pool, so the post-client switch left stale `-wal`/`-shm` handles and the first `Collection.add()` failed during compaction with `SQLITE_NOTADB` (error 26, "file is not a database"). WAL is now switched inside `_init_chroma_client` **before** the client opens the DB, is idempotent (a DB already in WAL is left untouched), pre-creates a fresh install's DB directly in WAL (so run #1 is already WAL, verified against chromadb 1.5.9), and is skipped on network filesystems (NFS/SMB/CIFS) where WAL is unsafe (chroma-core/chroma#7040 caveat), including UTF-8 mountpoints. Read-only startups were unaffected; only incremental writes hit the failure. Reported by @admincheg with an isolated A/B reproduction. 18 regression tests lock the ordering, idempotency, fresh-install pre-create and network-FS guard. - **fix(config)** — the `init`-generated `config.yaml` now enables 29 formats (code + infrastructure) instead of only `.md`/`.txt`/`.pdf`/`.docx`. The bundled `mcp_server/data/config.example.yaml` template previously shipped an explicit list with the new infra/code formats commented out, so anyone who ran `init` silently opted out of Go/Rust/YAML/Proto/SQL/etc; it now mirrors the root `config.example.yaml` (the 4 office/notebook formats and MetaTrader stay opt-in, commented). Also corrects the stale "20 formats" count to 35 across `README.md` and `docs/ARCHITECTURE.md`, and `12 MCP tools` to 13 in the npm README. - **fix(search)**: `QueryCache` never hit for the default dispatch path. In `KnowledgeOrchestrator.query()`, the per-result formatting loop reassigns the local name `search_method` (to label each result `hybrid`/`semantic`/`keyword`) after the cache lookup already ran, so the cache write stored under that clobbered value instead of the caller's actual dispatch parameter (`"auto"` by default). Every repeat of the same query missed the cache. The per-result label now uses its own variable; the parameter is untouched for the rest of the function. +- **fix(config)**: GH #208: `KNOWLEDGE_RAG_DIR` set to a relative path (e.g. `./my-data`) or tilde path (`~/rag`) now resolves correctly at startup. `BASE_DIR` applies `.expanduser().resolve()` so all derived paths (`config.yaml`, `data_dir`, `chroma_db`, `documents_dir`, `models_cache_dir`) are always absolute regardless of how the env var was written. Absolute paths are idempotent (no behavior change for existing users). Cross-platform safe — tested on Linux, Windows and macOS. ### v4.8.5 (2026-08-13) — Enterprise observability: `/health` probes + JSON structured logging (opt-in) diff --git a/mcp_server/config.py b/mcp_server/config.py index a435d35..5bcb0fe 100644 --- a/mcp_server/config.py +++ b/mcp_server/config.py @@ -96,7 +96,7 @@ def _is_project_root(path): _venv_dir = _venv_project_dir() if os.environ.get("KNOWLEDGE_RAG_DIR"): - BASE_DIR = Path(os.environ["KNOWLEDGE_RAG_DIR"]) + BASE_DIR = Path(os.environ["KNOWLEDGE_RAG_DIR"]).expanduser().resolve() elif _venv_dir is not None and (_venv_dir / "config.yaml").exists(): # Prefer venv parent if it has an actual config.yaml (editable installs, PyPI installs) BASE_DIR = _venv_dir diff --git a/tests/test_config.py b/tests/test_config.py index a0e0ee4..2f77e20 100644 --- a/tests/test_config.py +++ b/tests/test_config.py @@ -1,5 +1,8 @@ """Tests for configuration integrity.""" +import os +from pathlib import Path + from mcp_server.config import _merge_query_expansion_sources, config @@ -152,3 +155,42 @@ def test_query_expansion_groups_extend_legacy_entries(): assert merged["tb"] == ["triple barrier", "trip_barr", "legacy_alias"] assert "tb" in merged["triple barrier"] assert "trip_barr" in merged["triple barrier"] + + +class TestKnowledgeRagDirResolution: + """KNOWLEDGE_RAG_DIR must resolve relative and tilde paths to absolute.""" + + def test_relative_path_becomes_absolute(self, monkeypatch, tmp_path): + import importlib + + import mcp_server.config as config_module + + rel = "." + os.sep + "my-rag-data" + monkeypatch.setenv("KNOWLEDGE_RAG_DIR", rel) + monkeypatch.chdir(tmp_path) + importlib.reload(config_module) + + assert config_module.BASE_DIR.is_absolute() + assert config_module.BASE_DIR == (tmp_path / "my-rag-data").resolve() + + def test_absolute_path_stays_absolute(self, monkeypatch, tmp_path): + import importlib + + import mcp_server.config as config_module + + abs_path = str(tmp_path / "rag-store") + monkeypatch.setenv("KNOWLEDGE_RAG_DIR", abs_path) + importlib.reload(config_module) + + assert config_module.BASE_DIR == Path(abs_path).resolve() + + def test_tilde_path_expands(self, monkeypatch, tmp_path): + import importlib + + import mcp_server.config as config_module + + monkeypatch.setenv("KNOWLEDGE_RAG_DIR", "~/.knowledge-rag") + importlib.reload(config_module) + + assert config_module.BASE_DIR.is_absolute() + assert "~" not in str(config_module.BASE_DIR) From 6f68d918f4215ad87be41e39a2302492f8dcf961 Mon Sep 17 00:00:00 2001 From: Lyonzin Date: Thu, 3 Sep 2026 22:34:36 -0300 Subject: [PATCH 2/5] fix(test): use subprocess isolation for BASE_DIR resolution tests importlib.reload(config_module) corrupts module-global state (the config import replaces sys.stdout and rebuilds embedding profiles), causing 5 unrelated tests to fail.
