CI for csaxs_bec / test (push) Successful in 1m31s
Custom (non-EPICS) ophyd device for the Canon CR-N300 PTZ remote camera. Phase 1 (implemented): standalone control that works with the imaging stack absent. PTZ/zoom/focus exposed as positioners (move()/set() -> status, stop(), spec limits: pan +/-170 deg, tilt -30..+100 deg, 20x zoom); camera parameters (exposure/iris, gain, white balance, focus mode, presets) via read()/describe() with read-back verification; Manual + Continuous/Face/Tracking AF focus modes. Control plane (transport/, pure stdlib, no ophyd): - CameraTransport ABC; XCTransport implements the Canon XC Control Protocol (session open/claim/yield, HTTP/CGI) with an injectable opener; FakeTransport is a full in-memory simulator for offline mode and tests. Spec-defined CGI paths/params/axis encodings (BPE-7216-005) are isolated and flagged for hardware verification. Imaging plane (acquisition/, pure stdlib, no ophyd, not a control dependency): - FrameRingBuffer (bounded, thread-safe, stores compressed frames) and a persistent, fail-soft, instrumented StreamWorker. Phase-2 grab API (get_latest/get_latest_n/get_nearest, decode-on-grab) seamed in the device. Credentials come from env vars (CANON_<NAME>_USER/_PASSWORD), never YAML/Redis. Adds example device config (real + simulation), a README, and pytest coverage (transport mocked, ring buffer, stream worker, device logic) — no hardware required. No new third-party dependencies (Phase-2 decode uses cv2, already a csaxs_bec dependency). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
