Thumbnails are now keyed by blob_hash on disk so identical files share
a single set of thumbnails (icon/preview/large). For 4000 duplicate
files with the same content, this reduces thumbnail storage from 12,000
files to just 3.
Changes:
- get_thumbnail_path() keys by blob_hash instead of file_id
- get_thumbnail(), get_cached_thumbnail(), generate_all_sizes_background()
accept blob_hash parameter for disk dedup
- generate_all_sizes_background() fast path: if blob-hash thumbnails
already exist on disk, skip image processing entirely and just
populate moka cache for the new file_id
- delete_thumbnails() only invalidates moka cache (shared disk
thumbnails must not be deleted when one file is removed)
- delete_blob_thumbnails() added for GC; garbage_collect() now cleans
up orphaned thumbnail files alongside blob files
- External thumbnails (video frames) stored as ext-{file_id}.jpg
since they are client-generated and not dedup-able
- ThumbnailPort trait updated with blob_hash parameters
- All handler call sites updated (file_handler, preview_handler)
- Tests updated for new signatures
The folder upload path (uploadFolderEntries) used a flat 10s fetch
timeout for all files regardless of size. Large files like .CR2 RAW
images (~25MB) on slower networks (e.g. Raspberry Pi) exceeded this
timeout, causing the AbortController to kill the request before the
server received the full body — hence no server logs and 'unknown
error' on the frontend.
Changed to size-scaled timeout: 30s base + 2s per MB (min 10s).
A 25MB CR2 now gets ~80s instead of 10s.
Starting with PostgreSQL 18, the data directory (PGDATA)
of the Docker Image has changed to be version specific.
For PostgreSQL 18 it is /var/lib/postgresql/18/docker/.
This means that to persist data, mounts and volumes
should target the new location: /var/lib/postgresql/.
FixesDioCrafts/OxiCloud#281
- Move all sync I/O (id3::Tag, mp3_duration) into spawn_blocking via
extract_metadata_blocking() to avoid stalling Tokio worker threads
- Replace fetch_all with streaming .fetch() in reextract_all_audio_metadata
for O(1) memory usage regardless of audio file count
- Consolidate get_duration_secs into extract_metadata_blocking, eliminating
redundant file open (tag was read twice before)
- Replace blocking blake3::hash() with DedupService::hash_file() in
file_upload_service (create_file, update_file). Uses spawn_blocking +
mmap_rayon instead of blocking the Tokio async worker.
- Parallelize thumbnail resize+encode with rayon par_iter() for the 3
sizes (Icon, Preview, Large) inside spawn_blocking.
Replace hardcoded DEFAULT_MAX_CONCURRENT_DECODES=4 with adaptive
max_concurrent_decodes() that uses available_parallelism()/2 (min 2).
Matches the pattern already used in image_transcode_service.
Improves thumbnail throughput on 16+ core servers by 2-4x.
