Three gallery serving routes bypassed the getStorage() abstraction and
used fs.* directly against local paths. Worked in local-fs mode, 500'd
in S3 mode because the files only exist in the bucket. Reported by
@w1ll-i-code with a precise root-cause pointer at gallery.js:1138.
The admin photo serving route (adminPhotos.js) had already been
converted to use storage.stat + storage.get; the gallery side hadn't.
This PR brings the gallery routes in line.
Changes:
- Add getRange(relPath, start, end) to the StorageBackend interface +
LocalFsStorage (fs.createReadStream with start/end) + S3StorageBackend
(downloadStream with Range header). Needed for video range requests
on S3 — previously the photo route did fs.createReadStream(filePath,
{start, end}) which is local-only.
- /:slug/thumbnail/:photoId — read mtime via storage.stat, stream bytes
via storage.get. Watermark application path materializes the source
via withLocalCopy (no-op in local mode, downloads to a tmp file then
cleans up in S3 mode) so applyWatermark's sharp + fs.readFile still
works.
- /:slug/photo/:photoId — branches on source_origin: external/reference
photos still use the local fs path (NAS mounts are local), managed
photos use the storage abstraction. Video range requests pass through
to storage.getRange. Pre-generated watermarks served via storage too.
On-the-fly watermark generation uses withLocalCopy for managed photos.
- /:slug/hero/:photoId — hero images are always managed-storage keys
(imageProcessor.generateHeroImage writes via the storage abstraction),
so this just switches to storage.stat + storage.get. Watermark via
withLocalCopy.
Verified end-to-end against minio in dev:
POST /api/admin/photos/N/upload → photo + thumbnail land in S3
GET /api/gallery/<slug>/thumbnail/<id> → 200, JPEG 300x300 ✓
GET /api/gallery/<slug>/photo/<id> → 200, JPEG 1200x800 ✓
GET /api/gallery/<slug>/hero/<id> → 200, JPEG 1920x1080 ✓
ETag round-trip (If-None-Match) → 304 ✓
Backend logs → no errors
LocalFs regression: 13/13 smoke tests pass.
Closes#432.
