- Move OnlyOffice conversion out of worker subprocesses into async event loop
using httpx.AsyncClient with shared client and clean shutdown hook
- Add OOConversionManager with in-flight deduplication (asyncio.Future) and
configurable concurrency limit (OO_MAX_CONCURRENT=2)
- Add 10s total timeout for office previews via asyncio.wait_for
- Return 503 when OnlyOffice is unavailable, 504 on timeout
- Remove office handling from worker dispatch(); workers now only do
images, video, and PDFs
- Replace PNG tempfile bridge with framed binary input protocol on worker
stdin: (json_size)(data_size)(json)(raw_data)
- Add process_image_buffer() for in-memory AVIF conversion via pyvips
- Add office_previews to WS server message, cached every 30s from OO
availability check
- Frontend gates only office document previews on office_previews flag;
images, video, PDFs remain unconditional
- Change default OnlyOffice port from 8080 to 8988
