Lifecycle (internal/app + main.go):
- App.OnShutdown hooks run after the HTTP server drains, in
registration order: Worker.Shutdown (background jobs now drain
instead of dying on SIGTERM), DeviceAuthMiddleware.Stop (releases
the rate-limiter ticker), Handler.CloseScanner (fsnotify watcher
and scan log files)
Security headers:
- SecurityHeadersMiddleware (survivor of middleware/security.go,
renamed security_headers.go) is now on the echo stack: nosniff,
frame-deny, HSTS, CSP (unsafe-inline required by the sanctioned
theme flash guard + Alpine), referrer and permissions policy
Scanner settings cache:
- settings saves (UpdateScanSettings + ApplySetting for the three
scan keys) now invalidate MediaScanner's 30s settings cache via
SystemSettingsHandler.SetScanSettingsChanged, so changes apply on
the next poll instead of after the TTL
- MediaScanner.Close closes the scan logger, fixing a file-descriptor
leak on every per-item rescan (fresh scanners never closed logs)
Client fix:
- custom-section-builder's add/remove-selection buttons used inline
onclick attributes referencing module-scoped functions, which are
not global in a bundled ES module: the buttons threw ReferenceError.
Functions restored and exposed on window via declare global
Also fixes a pre-existing vet error (saveCoverImage copied
echo.Context by value, mutex included) and drops the per-key
SettingsCache.InvalidateKey variant left callerless by the
full-flush invalidation wiring.
- Add SettingsCache with TTL-based invalidation (30 seconds)
- Cache scan_poll_interval_seconds and auto_scan_enabled settings
- Reduce database queries from every poll/check to once per TTL period
- Improve error handling with proper fallback values
- Simplify boolean parsing with strings.ToLower for consistency
This optimization reduces database load when checking scan settings,
which occurs frequently during media scanning operations.
