v1.9.25 — Settings tab load time: 6.5 s → 0 ms

Caught during the v1.9.24 binary smoke test: GET /system/dependencies took ~6.5 s on the first cold call because it runs 20+ importlib.import_module() probes (torch, mediapipe, audiocraft, pyannote, onnxruntime, rembg, realesrgan, gfpgan, insightface, ...) plus an ffmpeg -version subprocess plus an ollama HTTP probe — all synchronously in one request. This blocked the Settings tab render on first open.

Fix

  • New module-level _deps_cache in opencut/routes/system.py with a threading.Lock and a 60-second TTL.
  • Cold call still pays the ~5 s import tax once; every subsequent call within the window returns from memory in <1 ms.
  • New ?fresh=1 query param bypasses the cache so the frontend can force a re-check after an install/uninstall.

Measured (via compiled PyInstaller exe)

cold call:   5513 ms   (20+ importlib + ffmpeg + ollama)
warm call:     87 ms   (HTTP roundtrip overhead only — cached in memory)
fresh=1:      173 ms   (bypasses cache; sys.modules warm)

~63x speedup on steady-state.

How this was found

Part of a rolling QA cycle: every tagged release gets an end-to-end binary smoke test against the PyInstaller exe (not just the Flask test client). That exercise caught v1.9.23's OPENCUT_PORT regression in v1.9.24, and now v1.9.25's dependency-check slowness.
