Replace hardcoded localhost:6379 values throughout codebase with environment-based configuration. Add REDIS_PORT support and allow REDIS_URL override for external Redis services. Configure Celery broker/result backend to use Redis settings with environment variable overrides.
Closes#762
- Add _cleanup_orphaned_crontab() helper function
- Delete old crontab when disabling backup schedule
- Delete old crontab when schedule settings change
- Prevents database bloat from unused CrontabSchedule records
- Row 1: Frequency, Day (if weekly), Hour, Minute, Period (if 12h)
- Row 2: Retention, Save button
- Use wrap=nowrap to keep time selectors on same row
- Set CrontabSchedule timezone to system timezone for accurate scheduling
- Replace time TextInput with hour/minute Select dropdowns for cleaner UX
- Remove UTC/local time conversion logic (handled by Celery)
- Add tests for timezone functionality in simple and advanced modes
Updated create_backup to use the system's configured timezone for backup
filenames instead of always using UTC. This makes filenames more intuitive
and matches users' local time expectations.
Changes:
- Import pytz and CoreSettings
- Get system timezone from CoreSettings.get_system_time_zone()
- Convert current UTC time to system timezone for filename timestamp
- Fallback to UTC if timezone conversion fails
- Internal metadata timestamps remain UTC for consistency
Example:
- System timezone: America/New_York (EST)
- Created at 3:00 PM EST
- Old filename: dispatcharr-backup-2025.12.09.20.00.00.zip (UTC time)
- New filename: dispatcharr-backup-2025.12.09.15.00.00.zip (local time)
This aligns with the timezone-aware scheduling already implemented.
The list_backups function was creating timezone-naive datetime objects,
which caused the frontend to incorrectly interpret timestamps.
Now uses datetime.UTC when creating timestamps from file modification time
(consistent with other usage in this file on lines 186, 216), so the ISO
string includes timezone info (+00:00). This allows the browser to properly
convert UTC timestamps to the user's local timezone for display.
Before: Backend sends "2025-12-09T14:12:44" (ambiguous timezone)
After: Backend sends "2025-12-09T14:12:44+00:00" (explicit UTC)
The frontend's toLocaleString() will now correctly convert to local time.
Frontend changes:
- Add advanced mode toggle switch for cron expressions
- Show cron expression input with helpful examples when enabled
- Display format hints: "minute hour day month weekday"
- Provide common examples (daily, weekly, every 6 hours, etc.)
- Conditionally render simple or advanced scheduling UI
- Support switching between simple and advanced modes
Backend changes:
- Add cron_expression to schedule settings (SETTING_KEYS, DEFAULTS)
- Update get_schedule_settings to include cron_expression
- Update update_schedule_settings to handle cron_expression
- Extend _sync_periodic_task to parse and use cron expressions
- Parse 5-part cron format: minute hour day_of_month month_of_year day_of_week
- Create CrontabSchedule from cron expression or simple frequency
- Add validation and error handling for invalid cron expressions
This addresses maintainer feedback for "custom scheduler (cron style) for more control".
Users can now schedule backups with full cron flexibility beyond daily/weekly.
Dramatically improve EPG refresh performance by parsing the XML file once
per source instead of once per channel. The new implementation:
- Pre-filters to only process EPG entries mapped to actual channels
- Parses the entire XML file in a single pass
- Uses O(1) set lookups to skip unmapped channel programmes
- Skips non-mapped channels entirely with minimal overhead
For EPG sources with many channels but few mapped (e.g., 10,000 channels
with 100 mapped to channels), this provides approximately:
- 99% reduction in file open operations
- 99% reduction in XML file scans
- Proportional reduction in CPU and I/O overhead
The parse_programs_for_tvg_id() function is retained for single-channel
use cases (e.g., when a new channel is mapped via signals).
Fixes inefficient repeated file parsing that was occurring with large
EPG sources.
- Simplify to database-only backups (remove data directory backup)
- Update UI to match app styling patterns:
- Use ActionIcon with transparent variant for table actions
- Match icon/color conventions (SquareMinus/red.9, RotateCcw/yellow.5, Download/blue.5)
- Use standard button bar layout with Paper/Box/Flex
- Green "Create Backup" button matching "Add" pattern
- Remove Card wrapper, Alert, and Divider for cleaner layout
- Update to Mantine v8 Table syntax
- Use standard ConfirmationDialog (remove unused color prop)
- Update tests to remove get_data_dirs references
- Added m3u_account__name to backend ordering_fields in StreamViewSet
- Implemented field mapping in frontend to convert column IDs to backend field names
- Added sort buttons to both Group and M3U columns with proper icons
- Sort buttons show current sort state (ascending/descending/none)
- Maintains consistent UX with existing Name column sorting
