vvzvlad	f0e38b9776	perf(core): improve async handling and caching performance ... Convert delayed_delete_file to async and use asyncio.sleep. Add pre‑semaphore cache hit to serve cached files without acquiring the download semaphore. Set SQLite busy_timeout to reduce lock errors. Introduce a diagnostics counter for pending _persist_media_file_id_async tasks. Refactor flag extraction to accept pre‑generated HTML and compute html body once. Batch reply enrichment in RSS generator to minimize API calls. Store cached messages directly in tg_cache and add fallback for legacy double‑pickle format. BREAKING CHANGE: delayed_delete_file is now async and must be awaited.	2026-05-18 00:08:46 +03:00
vvzvlad	57a96044bc	feat(db): add mime_type column and caching helpers ... Add a new `mime_type` column to the media_file_ids table and provide functions to get and set cached MIME types. The API now attempts to retrieve the MIME type from the database before falling back to python-magic, persisting the detected type for future requests. This reduces I/O overhead and improves response performance. Also adjust logging to debug level to reduce noise.	2026-04-06 23:46:22 +03:00
vvzvlad	c9b0d2ffc9	feat(db): replace media file ID JSON store with SQLite ... Switch persistence of media file identifiers from a JSON file to a SQLite database. Introduce DB_PATH, init_db_sync, upsert, update, and removal functions. Remove json-repair dependency and related locking logic. Update api_server and post_parser to use the new database helpers. BREAKING CHANGE: media_file_ids.json is no longer used; existing data must be migrated to the new SQLite database.	2026-04-05 20:20:37 +03:00
