From 41f3428f20ab5e5efe2c2cd0c4495120615d85bd Mon Sep 17 00:00:00 2001 From: Devanshu Rajesh Chicholikar Date: Tue, 24 Feb 2026 14:15:58 -0500 Subject: [PATCH 1/5] refactor: split playground.py (1306 lines) into 6 focused modules playground.py was 1306 lines -- 6.5x our 200-line guideline. Split into a package with focused modules: playground/__init__.py (29 lines) -- combines routers, re-exports playground/helpers.py (80 lines) -- constants, DEMO_REPO_IDS, session utils playground/search.py (218 lines) -- POST /search, GET /repos, GET /stats playground/session.py (68 lines) -- GET /limits, GET /session playground/validation.py(185 lines) -- POST /validate-repo, GitHub API helpers playground/indexing.py (247 lines) -- POST /index, GET /index/{job_id} Total: 827 lines across 6 files (was 1306 in 1 file). Net: -479 lines removed during cleanup. main.py unchanged -- imports router and load_demo_repos from routes.playground which __init__.py re-exports. Test updates: - test_validate_repo.py: updated imports + patch targets - test_anonymous_indexing.py: updated 40+ patch decorators to point to correct new modules (indexing.* for indexing tests, search.* for search tests) 289 tests pass.

All playground modules now pass PEP8 120-char max. Skipped (duplicates 4th+ time): sync Redis calls in async endpoints, create_session cookie flow. count_code_files fallback to size estimate is intentional -- tree API fails for large valid repos. 289 tests pass. --- backend/routes/playground/search.py | 24 ++++++++++++++++++++---- backend/routes/playground/validation.py | 5 ++++- 2 files changed, 24 insertions(+), 5 deletions(-) diff --git a/backend/routes/playground/search.py b/backend/routes/playground/search.py index 05891a4..391b71e 100644 --- a/backend/routes/playground/search.py +++ b/backend/routes/playground/search.py @@ -98,7 +98,11 @@ def _validate_user_repo_access( expired_at=indexed_repo.get("expires_at"), session_token=token_preview) raise HTTPException( status_code=410, - detail={"error": "repo_expired", "message": "Repository index expired.

Fix: added @patch('routes.playground.indexing.redis_client', MagicMock()) to TestIndexEndpoint, TestSessionConflict, and TestStatusEndpoint. TestStatusEndpoint uses MagicMock(get=MagicMock(return_value=None)) so test_job_not_found_returns_404 exercises the real AnonymousIndexingJob code path (redis.get returns None -> job not found -> 404). 289 tests pass locally.
