mule-image was generating and storing three WebP sizes per photo in /data/thumbs while Nextcloud already keeps its own previews for the same source files. Frontend thumbnail requests now proxy NC's /index.php/core/preview keyed by the photo's Nextcloud fileid, authenticated with the owner's encrypted app password. - new column photos.nextcloud_fileid (alembic 0018) plus an index - get_preview_async + fetch_fileid helpers in nextcloud_dav.py - thumb route proxies NC primary, falls back to /data/thumbs (legacy rows / NC unreachable) so a single-file revert restores the old path - extract_metadata caches the fileid on first run for new photos - generate_thumbnails now writes only medium since the vision worker still loads it from disk; small + large drop out of the worker path - backend/scripts/backfill_nextcloud_fileid.py for one-shot population of existing rows: docker exec mulita-backend python -m scripts.backfill_nextcloud_fileid X-Mule-Thumb-Source response header marks each request 'nextcloud' or 'disk' for observability while the rollout settles.

"""Add photos.nextcloud_fileid for NC preview proxying

Revision ID: 0018_photos_nextcloud_fileid
|
|
Revises: 0017_photos_list_index
|
|
Create Date: 2026-05-11
|
|
|
|
The thumbnail endpoint will proxy Nextcloud's /index.php/core/preview
|
|
instead of generating and serving its own WebP cache under /data/thumbs.
|
|
That requires storing each photo's Nextcloud numeric fileid alongside
|
|
the row. NULL is allowed because legacy / non-NC photos still exist
|
|
and the handler keeps the on-disk fallback for them.
