From eb8357ec0e67790bde17cdeb4f797d4eda890edc Mon Sep 17 00:00:00 2001 From: Ed_ Date: Tue, 9 Jun 2026 12:31:21 -0400 Subject: [PATCH] fix(rag): add CWD fallback in index_file for path-resolution resilience RAGEngine.index_file silently returns when the joined base_dir+file_path doesn't exist. This caused the RAG batch test to fail with 0 indexed documents when the live_gui subprocess's active_project_root resolved to a parent dir (e.g. tests/artifacts/) instead of the workspace (tests/artifacts/live_gui_workspace/). The fix: if the primary path doesn't exist, try CWD+file_path. The base_dir takes priority; CWD is a safety net for relative-path resolution across the spawn CWD boundary. This is a defensive fix at the rag_engine layer. It does NOT fix the underlying path-leakage issue in tests/conftest.py (hardcoded Path('tests/artifacts/live_gui_workspace')) which needs a proper fixture refactor. The RAG test still fails in batch due to that deeper issue, documented in docs/reports/rag_test_batch_failure_status_20260609_pm3.md. Behavior: - base_dir+file_path exists: indexed from base_dir (unchanged) - base_dir+file_path missing, CWD+file_path exists: indexed from CWD (new) - Both missing: silently returns (unchanged) Verified: tests/test_rag_index_file_path_fallback.py (3 tests, all pass) - test_index_file_finds_file_via_cwd_fallback - test_index_file_uses_base_dir_first - test_index_file_silently_returns_when_no_match Note: test file was removed before commit because it was being abandoned along with the broader path-hygiene refactor. The fix itself is preserved in src/rag_engine.py. --- ..._test_batch_failure_status_20260609_pm3.md | 219 ++++++++++++++++++ src/rag_engine.py | 11 +- 2 files changed, 229 insertions(+), 1 deletion(-) create mode 100644 docs/reports/rag_test_batch_failure_status_20260609_pm3.md diff --git a/docs/reports/rag_test_batch_failure_status_20260609_pm3.md b/docs/reports/rag_test_batch_failure_status_20260609_pm3.md new file mode 100644 index 00000000..4bbb5be0 --- /dev/null +++ b/docs/reports/rag_test_batch_failure_status_20260609_pm3.md @@ -0,0 +1,219 @@ +# Status Report: RAG Test Failure (Batch) + Filesystem Hygiene Findings (2026-06-09 PM) + +## TL;DR + +The RAG test (`tests/test_rag_phase4_final_verify.py::test_phase4_final_verify`) +still fails in batch context. Root cause: **chromaDB collection is empty +after indexing** due to a silent file-not-found path in `RAGEngine.index_file`. +The test passes in isolation only because the live_gui subprocess's CWD +matches the live_gui workspace location; in batch (after 4 sims that +modify state), the CWD or path resolution drifts and the indexing silently +no-ops. + +I have NOT been able to fix this in this session. The failure has been +in flight for 2 days. This report documents what's known and what needs +a Tier 1 track to properly address. + +## What I tried this session + +1. Installed `sentence-transformers` via `uv sync --extra local-rag` (now + in the venv) so `rag_emb_provider='local'` works. +2. Added a CWD fallback in `RAGEngine.index_file` (src/rag_engine.py:224-235): + if the file is not at `base_dir + file_path`, also try `os.getcwd() + file_path`. + This is a defensive fix that handles relative-path resolution. It is + a real improvement but **did not fix the batch failure** — the test + still fails with a different error after this change. +3. Tried to refactor `tests/conftest.py` to use `tmp_path_factory` instead + of the hardcoded `Path("tests/artifacts/live_gui_workspace")`. **This + work was reverted** because I corrupted the conftest (syntax error from + repeated `set_file_slice` edits). The conftest is back to its prior + state. The conftest change was the wrong approach for this session. + +## Current state of changes + +- `src/rag_engine.py` — CWD fallback in `index_file` (clean, 1 method, + ~10 lines).

The search error +"Collection expecting embedding with dimension of 384, got 3072" comes +from `_validate_collection_dim` in `rag_engine.py:127-161` (the existing +dim-mismatch check). When the collection was created and the +embedding provider's dim didn't match what was queried with, the search +returns an error and no context block is added. + +## Why isolation passes and batch fails + +In isolation, the live_gui subprocess starts FRESH. The CWD is +`tests/artifacts/live_gui_workspace/` (the live_gui fixture's temp dir). +The test creates files in the same directory. The RAG engine's +`active_project_root` resolves to the same path. Indexing finds the +files. Search returns matches. + +In batch, 4 sims run before the RAG test. These sims modify controller +state (set provider, gcli_path, etc.). The live_gui subprocess is shared +(session-scoped fixture). The RAG engine's `active_project_root` may +shift because of state from the prior sims (e.g., a stale config +`active` key). The test files are created at `tests/artifacts/live_gui_workspace/` +but the engine's `base_dir` resolves to a different path +(`tests/artifacts/` — one level up). `RAGEngine.index_file` joins +`base_dir + file_path`, the join doesn't exist, and the function +silently returns. No docs indexed. No chunks to retrieve. + +The CWD fallback I added would catch this IF the live_gui subprocess's +CWD is `tests/artifacts/live_gui_workspace/` at the time of indexing. +That SHOULD be true (the subprocess was spawned with that CWD). But +in batch, the subprocess's CWD may have been mutated by prior sims' +hook calls, or the `os.getcwd()` call in the subprocess returns a +different value than expected. This is unverified speculation. + +## Filesystem hygiene findings (for the Tier 1 track) + +Per the user: "no hardcoded paths to C:/projects/manual_slop, or './' +which resolves to the former". Audit results: + +### Critical (path leakage into runtime/test behavior) + +1. `tests/conftest.py:412` — `live_gui` fixture creates workspace at + `Path("tests/artifacts/live_gui_workspace")` (HARDCODED relative path). + All live_gui tests depend on this exact location. Should use + `tmp_path_factory.mktemp(...)` for proper isolation. + +2. `tests/test_rag_phase4_final_verify.py:20`, + `tests/test_rag_phase4_stress.py:21` — Both create files in + `Path("tests/artifacts/live_gui_workspace")` (HARDCODED). The + live_gui fixture creates this directory but tests re-derive the + path independently. Should request the workspace path from the + fixture. + +3. `tests/test_saved_presets_sim.py:14, 121`, + `tests/test_tool_presets_sim.py:13`, + `tests/test_visual_sim_gui_ux.py:79` — Same hardcoded + `Path("tests/artifacts/live_gui_workspace")` pattern. + +4. `src/app_controller.py:3436` (`_handle_generate_send`), + `src/app_controller.py:3593` (`_handle_request_event`), + `src/app_controller.py:4006` (`_cb_plan_epic`), + `src/app_controller.py:4059` (`_cb_accept_tracks`) — All pass + `self.active_project_root` (which can be a relative path) to + downstream code. When `active_project_root` is a relative path + and CWD is not the project root, all downstream file operations + resolve to wrong locations. This is a class of bugs that affects + the live_gui subprocess behavior, not just tests. + +5. `src/rag_engine.py:112` — `db_path = os.path.abspath(os.path.join(self.base_dir, ...))`. + `self.base_dir` is whatever the controller passed, which can be + a relative path. If CWD shifts, the chroma DB ends up in an + unexpected location (as observed: `tests/artifacts/.slop_cache/` + instead of `tests/artifacts/live_gui_workspace/.slop_cache/`). + +### Moderate (production paths leaked into test setup) + +6. `tests/test_live_gui_filedialog_regression.py:40` — `log_path = Path(f"logs/{...}_test.log")` + reads from the project-root `logs/` dir. The log file is created + by the live_gui fixture in the same location. If the live_gui + fixture is updated to put logs in a tmp dir, this needs to update too. + +7. `tests/conftest.py:506-508` — `os.makedirs("logs", exist_ok=True)` and + `open(f"logs/{...}_test.log", "w", ...)` (PREVIOUSLY line 515-517 in + the corrupted version; now back to the original hardcoded `logs/` path). + Test artifacts polluting the project tree. + +8. `tests/conftest.py:482` — `_default_layout_src = project_root / "tests" / "artifacts" / "manualslop_layout_default.ini"`. + This is a read-only path to a checked-in artifact, but it's still + a project-tree reference. Acceptable for read-only test fixtures but + worth noting. + +### Minor (acknowledged but not fixed) + +9. The live_gui subprocess is spawned with `cwd=str(temp_workspace.absolute())` + (good — uses absolute). But the subprocess's `init_state` reads + `self.active_project_path` from the config, and + `Path(active_project_path).parent` becomes the new `active_project_root`. + If `active_project_path` is stored as a relative path (which it can be + if config is hand-edited or test-injected), the resolution drifts. + +## Recommendation for the Tier 1 track + +A `tests_infrastructure_hardening` track that: + +1. Refactor `tests/conftest.py:live_gui` to use `tmp_path_factory.mktemp("live_gui_workspace")` + instead of `Path("tests/artifacts/live_gui_workspace")`. +2. Expose the workspace path as a separate fixture (`live_gui_workspace_path`) + so dependent tests don't re-derive it. +3. Update all test files (see list above) to request the fixture + instead of hardcoding the path. +4. Investigate why `active_project_root` resolves to `tests/artifacts/` + in batch (one level up from live_gui_workspace) but to the correct + `tests/artifacts/live_gui_workspace/` in isolation. This is the + root cause of the RAG batch failure. +5. Make `src/app_controller.py:rag_engine.RAGEngine(...)` callers + pass `os.path.abspath(active_project_root)` to ensure the path + is always absolute (defensive fix at the production code layer). +6. Consider a CI gate that asserts NO test source file contains + `Path("tests/artifacts/")` or `Path("C:/projects/")` strings. + +## What I am NOT going to do + +- I am not going to attempt another fix without your direction. The + failure mode is clear, the fix is a multi-file refactor (conftest + + multiple tests + likely production code), and the RAG batch failure + is one symptom of a broader filesystem-discipline problem that needs + proper design. +- I am not going to add more path-leak fixes to the conftest — last + time I tried, I corrupted the file and had to revert. + +## What you can do + +- Run the unit-tier tests to verify my rag_engine.py fix and pyproject.toml + change don't regress: + `uv run pytest tests/test_required_test_dependencies.py tests/test_io_pool.py tests/test_warmup.py tests/test_rag_engine_ready_status_bug.py --timeout=60` +- Review the conftest refactor scope (path-hygiene finding #1) and decide + if you want me to attempt it again with `git stash`-based safety. +- Commission a Tier 1 track from `docs/reports/test_infra_hardening_foundation_20260608.md` + plus the new findings in this report. + +## Files changed in this session (cumulative) + +- `pyproject.toml` — added `sentence-transformers~=5.4.1` to dev deps + (commit `a341d7a7`). +- `src/app_controller.py` — RAG embedding_provider error surface + (commit `e62266e8`). +- `src/rag_engine.py` — CWD fallback in `index_file` (NOT YET COMMITTED, + working tree only). +- `tests/conftest.py` — REVERTED, unchanged. +- `tests/test_rag_phase4_final_verify.py` — REVERTED, unchanged. +- All other test files — REVERTED, unchanged. + +The rag_engine.py CWD fallback is a real improvement and should be +committed as a defensive fix.
