The PRAGMA journal_mode=WAL returns 'wal' even on CIFS mounts where
WAL shared-memory actually fails. Now we do a concrete test write after
setting WAL mode; if it fails, we close the connection, remove stale
WAL/SHM files, reopen in DELETE mode.
When the data directory is on a CIFS/SMB mount (or other filesystem
lacking mmap shared-memory support), SQLite WAL mode fails with
'locking protocol' or 'readonly database' errors. The init_db function
now detects this and falls back to DELETE journal mode automatically.
Version:
- New app/__version__.py with 'dev' fallback for local dev
- Dockerfile injects APP_VERSION build arg from CI tag
- Health endpoint and footer now show actual release version
- Test updated to accept 'dev' in non-Docker environments
File size:
- Capture filesize/filesize_approx from yt-dlp extract_info
- Write to DB via update_job_progress and broadcast via SSE
- New 'Size' column in download table (hidden on mobile)
- formatSize helper: bytes → human-readable (KB/MB/GB)
- Frontend store picks up filesize from SSE events
- create_session uses INSERT OR IGNORE to handle concurrent requests
with same session cookie (race when multiple requests arrive before
the first INSERT commits)
- Widen actions column 110px→130px to fit 3 action buttons without
overflowing (was causing 4px horizontal scrollbar)
- Widen status column 100px→120px for DOWNLOADING badge breathing room
Backend:
- New error_log table: url, domain, error, format_id, media_type,
session_id, created_at
- log_download_error() called when yt-dlp throws during download
- GET /admin/errors returns recent entries (limit 200)
- DELETE /admin/errors clears all entries
- Manual purge also clears error log
- Domain extracted from URL via urlparse for grouping
Frontend:
- New 'Errors' tab in admin panel (Sessions, Storage, Errors, Settings)
- Each error entry shows: domain, timestamp, full URL, error message,
format/media type metadata
- Red left border + error-colored message for visual scanning
- Clear Log button to wipe entries
- Empty state: 'No errors logged.'
Error entries contain enough context (full URL, error message, domain,
format, media type) to paste into an LLM for domain-specific debugging.
