- Use ffmpeg CLI directly for HEIC/HEIF previews (bypassing pyvips which
cannot encode >8-bit AVIF on current system). ffmpeg handles tile
assembly, EXIF rotation, HDR metadata and ICC profiles automatically.
- pyvips remains primary for other image formats; ffmpeg is fallback.
- Simplify _get_image_dimensions() to use pyvips header read for all
formats including HEIC, with ffprobe as fallback.
- Move all imports to top of preview.py; remove lazy OnlyOffice import.
- Worker pool: add readiness handshake (\x01 byte), bounded idle wait
with PREVIEW_TIMEOUT, eager module import before signalling.
- Fix dispatch data check bug (was 'if data is not None' -> 'if data').
- Add logger.exception for unhandled preview/dispatch errors.
- EmojiFormatter now includes tracebacks for exception logs.
- Return 503 on preview timeouts instead of 504.
Replace Aspose.Words with OnlyOffice Document Server for generating
bitmap previews of office documents (Word, Excel, PowerPoint, etc.).
Backend:
- Add cista/onlyoffice.py conversion client
- Convert office docs directly to PNG via OnlyOffice, then AVIF via pyvips
- Make office previews optional based on OnlyOffice availability
- Remove Aspose.Words dependency and all related code
- Add spreadsheet and presentation format support
Frontend:
- Mark office files as previewable in Document.ts
- Add office extensions to MediaPreview.vue preview list
- Fix pre-existing @ts-ignore in HeaderMain.vue
Tests:
- Fix test_lrucache.py parameter name (open -> opener)
Also run ruff format across the codebase to satisfy linter checks.
Implement complete WebDAV file serving compatible with various clients from Windows File Explorer to more specialized sync tools. The old control WebSocket has been updated to part-DAV, part REST API instead. Implemented user:pass BASIC auth. Added UI and backend for creating tokens that avoid the need to use actual username and password for requests from CLI or DAV.
