LeoVasanko f1e16b7abe Preview: add pdf+pyvips encode path and simplify timings 2026-04-25 00:20:19 +00:00
LeoVasanko d5ff7757c8 Preview: persistent worker pool, fast AVIF encode, access-log timing
- Add preview_worker.py: long-lived subprocess; JSONL request / framed binary
  response protocol (BLAKE3 checksum + LE uint32 sizes + msgspec JSON + payload)
- Add _PreviewWorkerPool: asyncio queue-based pool; kill+replace workers on timeout,
  checksum error, or protocol error; PREVIEW_TIMEOUT=3s, PREVIEW_WORKERS=cpu-scaled
- Use pyvips effort=0,strip=True for fast AVIF thumbnails; CISTA_PIL=1 env forces Pillow
- Report load/process/save ms in PreviewResponse; inject into access log via req.ctx._log_extra
- Wire start/shutdown_preview_workers into Sanic lifecycle hooks (app.py)
- Call configure_main_logging() after Sanic() to install emoji formatter
- Silence worker stderr (DEVNULL)
