- Trim document extension list to common office formats only
(doc/docx/xls/xlsx/ppt/pptx/odt/ods/odp/rtf), removing txt/md/csv/html/xml/etc.
- Simplify Doc getters: merge guard clauses into single returns
(img, previewable, previewurl, ext).
- Simplify MediaPreview.preview() into single boolean expression.
- Use global FILE_TYPES instead of inline extension lists.
- 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.
- MediaPreview.vue: only render <img> for non-video, non-audio items
(video/audio already have their own player containers)
- Document.ts: limit previewurl to previewable files (was checking only .complete)
- Use modern tooling uv and bun
- Various changes to work with latest PyAV and PIL that have changed their API
- Improved image, video and document previews (uses AVIF, renders AVIF/HEIC/videos in HDR, faster processing)
- Fix a server hang in some cases where a folder was moved or renamed
- Log exceptions instead of only returning 500 response to client
- Log timing of preview generation functions
- Default to quality 50 in previews (previously 40)
