_get_image_dimensions now relies solely on pyvips header reading.
If pyvips cannot read the header the function returns None and the
caller encodes at full resolution rather than falling back to ffprobe.
Remove unused stdlib json import.
- 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.
- 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
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.
Increases block size to 16 MiB and adjusts progress display to work smoothly with that. Also removes download WS that was already unused. Provides faster upload speed than over WS.
