Month: 2026-04 Summary: - Key features delivered: - User-Uploaded Track Playback Enhancements in Metrolist: robust playback of user-uploaded YouTube Music tracks with improved metadata parsing, authentication handling, and stream URL management. This enables private/uploaded tracks to be identified, authenticated, and played reliably within queues. (Linked commit: 7f3f4ea7bdcba78944baefe7f8db32eb002acb34) - Major bugs fixed: - Fixed uploaded/private tracks being dropped from queues due to metadata gaps and misclassified auth paths. - Hardened stream URL handling with cookie-based authentication for private streams; ensured cookies are attached only to YouTube-related hosts. - Improved error handling for rate limits (HTTP 429) and 403 scenarios; implemented fallback and retry improvements. - Improved data handling for missing artist/album IDs and guarded playlist ID checks to minimize false positives. - Overall impact and accomplishments: - Significantly improved reliability and UX for user-uploaded content, enabling private uploads to play consistently and reducing playback failures. Enhanced security and correctness of auth flows, leading to better retention for uploaded-content features. - Technologies/skills demonstrated: - OkHttp interceptors for cookie management; NewPipe integration and multi-client stream selection logic; resilient error handling for network responses; code hygiene improvements (constants extraction, Timber logging, null-safety).
