Podman rootless containers with overlay storage do not propagate inotify
events through bind mounts, making the fsnotify file watcher ineffective.
This caused new files added on the host to go undetected until the
5-minute full-filesystem-walk polling fallback caught them.
Add a lightweight directory mtime polling mechanism that runs every 10
seconds, checking stat() on all subdirectories under watched library
folders against a cached mtime value. When a directory's mtime changes
(indicating files were added/removed/renamed), it feeds into the existing
markDirectoryDirty() → processDirtyDirectories() → job queue pipeline.
Changes:
- Add dirMtimes cache + mutex to MediaScanner struct
- Add seedDirectoryMtimes() to populate cache on startup (prevents
false-positive flood on first poll)
- Add pollDirectoryChanges() goroutine (10s ticker) and
checkDirectoryMtimes() (walks directories, compares mtimes)
- Launch mtime poller from WatchChanges() alongside existing goroutines
- Rename StartPolling logs to [ORPHAN-CLEANUP] to clarify its role
- Change default poll interval from 60s → 30m (new file detection now
handled by the fast mtime poll; full sync focuses on orphan cleanup)
- Update GetScanSettings default from 60 → 1800 seconds
- Add 5 tests: seed cache, skip nonexistent, detect new dir, skip
unchanged, detect modified dir
Expected result: new files detected in ~20 seconds (10s poll + 10s
debounce) regardless of inotify/container support.
- Add FormatInTimezone and FormatTimestamptzInTimezone helpers
in templates/utils.go for timezone-aware time display
- Add Timezone field to templates.User struct
- Pass user timezone from DB to template context in helpers.go
- Add timezone update handling in auth.go UpdateProfile with
validation via time.LoadLocation
- Add UpdateTimezoneSettings handler in system_settings.go for
admin system-wide default timezone using UpdateSystemSetting
Replace direct error equality checks (err == pgx.ErrNoRows, err != http.ErrServerClosed)
with the idiomatic errors.Is() function throughout handlers, services, middleware, and app
startup. This correctly handles wrapped error chains.
Also replace a raw type assertion (*HTTPError) with errors.AsType[*HTTPError]() in the
error handler middleware for consistency.
Additionally, rename shadowed variables for clarity:
- sidecar.go: config -> sidecarConfig, systemConfig (shadowed package-level vars)
- media_scanner.go: uuid -> uuidString (shadowed the uuid package import)
- Update validation to use scan_poll_interval_seconds field (1-3600 seconds)
- Update all test cases and assertions to use new field name
- Update integration test to reflect new field name
Create new SystemSettingsHandler for managing system-wide scan settings:
- GetScanSettings: retrieve scan frequency and auto-scan status
- UpdateScanSettings: update scan settings (15-1440 minutes range)
- Admin-only access (no user-specific data)
- Key-value based storage instead of per-user settings
Replaces per-user scan settings with centralized system configuration.
This handler is used by /api/libraries/scan-settings endpoints.
