- Added `dispatcharr.settings_test` for isolated testing, automatically creating an empty PostgreSQL test database and ensuring transaction isolation during tests.
- Updated `manage.py` to switch to the test settings when running tests.
- Enhanced the CONTRIBUTING.md file with detailed instructions on running the backend test suite and handling Celery tasks in tests.
- Refactored test cases to use static methods for `worker_id` in `test_process_label.py` and adjusted assertions in `test_user_preferences.py` for better clarity and correctness.
- Improved `xc_get_vod_streams` and `xc_get_series` functions to utilize a new helper method for fetching distinct relations based on account priority, significantly reducing memory usage and response times for large libraries.
- Updated the handling of VOD streams to avoid unnecessary ORM instantiation, enhancing performance for endpoints dealing with extensive movie and series data.
- Added comprehensive tests to ensure the correctness of the new logic and verify that the highest priority relations are correctly selected.
- Updated the `generate_dummy_programs` function to include `export_lookback` and `export_cutoff` parameters, allowing for more precise control over the EPG data generation window.
- Added a new test case to verify that future events are correctly represented in the grid window, ensuring upcoming fillers are displayed as expected.
- Moved the `programme_index` from the `EPGSource` model to a new `EPGSourceIndex` table, ensuring that the large JSON blob is only loaded when explicitly accessed, thus improving query performance and memory efficiency.
- Updated related queries and API views to utilize the new structure, including adjustments to EPG generation and import logic to prevent unnecessary data loading.
- Enhanced memory management in the EPG grid endpoint to reduce worker RSS during response handling.
- Moved all XMLTV output logic from `apps/output/views.py` to `apps/output/epg.py`, streamlining the codebase and maintaining the existing HTTP endpoint functionality.
- Updated related tests and references to ensure proper integration with the new module structure.
- Streamlined `generate_epg()` to incrementally stream EPG data without loading the entire guide, improving memory efficiency.
- Reduced database load by deferring the fetching of large `programme_index` blobs, enhancing response times for EPG generation.
- Introduced a composite index on `(epg_id, id)` in `ProgramData` to optimize query performance during EPG exports.
- Updated tests to ensure proper functionality and performance of new features.
The range-conflict warning classified each channel in the configured range as either this config's own auto-sync output or a real conflict, comparing each occupant against the source group. When a group sets a group_override, auto-sync creates its channels in the override target group, so the config's own channels failed that comparison and were misclassified as a conflict.
- Add effectiveSyncGroupId to resolve the group the sync's channels actually land in (the group_override target when set, otherwise the source group).
- Compare occupants against that effective target, so the config's own output is recognized while genuine conflicts (manual channels, channels from another account, channels in a different group, user-pinned numbers) still warn.
- Add Vitest coverage for the helper, the override case, and an over-suppression guard, plus a backend test asserting the numbers-in-range endpoint reports the override target group.
- Optimized `generate_epg()` to reduce database queries by prefetching ordered channel streams and implementing a new method for custom dummy epg name matching.
- Enhanced handling of dummy EPG sources to minimize SQL round-trips, improving performance for large guides with numerous custom-dummy channels.
- Implemented robust DB connection management in `refresh_epg_data` to handle transient errors, ensuring reliable status updates for EPG sources.
- Added retry logic for database queries and improved error handling to prevent task failures from unhandled exceptions.
- Updated EPG source status handling to ensure accurate reporting of errors and terminal states during refresh operations.
- Updated `get_streams` method in `ChannelSerializer` to use prefetched `channelstream_set`, improving performance by reducing database queries.
- Added `ChannelListIncludeStreamsQueryTests` to ensure that the number of queries remains stable as channels grow, verifying efficient stream inclusion in API responses.
- Implemented `ensure_custom_properties_dict()` to normalize custom properties across various models and serializers, addressing issues with legacy JSON-encoded strings.
- Updated M3U account and channel group models to ensure custom properties are consistently stored as dictionaries during save operations.
- Enhanced Celery task management by ensuring old DB connections are closed before and after tasks, improving reliability and preventing errors during account refresh operations. (Fixes#1338)
- Implemented `normalize_server_url()` to standardize account server URLs, ensuring that on-demand live URLs are built correctly without including API endpoints or query parameters.
- Updated `get_transformed_credentials()` and stream URL generation in `M3UMovieRelation` and `M3UEpisodeRelation` to utilize the new normalization function, improving URL handling for Xtream Codes accounts.
- Enhanced the live proxy to release geventpool DB connections more effectively across various paths.
- Implemented `close_old_connections()` in `stream_ts()`, `generate_stream_url()`, `get_stream_info_for_switch()`, `get_alternate_streams()`, `get_connections_left()`, and the cleanup process in `StreamGenerator`, ensuring that clients do not hold onto pool slots unnecessarily during streaming operations.
- Added a new function `_is_uwsgi_worker` to accurately identify when the application is running within a uWSGI worker.
- Updated `get_process_role` to label processes as "uwsgi" based on the new function or command-line arguments, improving process role accuracy.
- Expanded unit tests to cover various scenarios for uWSGI role detection, ensuring robust validation of the new logic.
- Introduced `lookup_by_name_year` function to limit database scans for movies and series without TMDB/IMDB IDs, enhancing performance by scoping lookups to current batch names.
- Updated `process_movie_batch` and `process_series_batch` to utilize the new lookup function, reducing memory usage and improving efficiency.
- Registered `refresh_vod_content` and `batch_refresh_series_episodes` for post-task memory cleanup in Celery, ensuring better resource management during VOD content refreshes.
- Improved memory cleanup by invoking `gc.collect()` after batch processing in `process_m3u_batch_direct` and `collect_xc_streams`, ensuring timely release of resources.
- Added tests to verify that garbage collection is triggered appropriately after batch operations.
- Introduced a new module to determine the process role based on command-line arguments, enhancing PostgreSQL connection labeling for better monitoring.
- Updated the database connection parameters to include the application name derived from the process role.
- Added unit tests to validate the process role detection logic for different scenarios, including Celery and uWSGI.
- Replaced the plugin listing mechanism with a more efficient handler iteration for event actions.
- Enhanced logging to provide clearer insights into the dispatching process and plugin action execution.
- Added error handling to ensure that failures in one plugin action do not block subsequent actions.
- Updated tests to cover new behavior and ensure proper handling of enabled and disabled plugins.
