Jan 1, 2025In 2025-01, the team focused on stability, correctness, and developer ergonomics in bbc/sofie-core. Key outcomes include targeted bug fixes, a minor UX improvement for debugging, and a dependency upgrade that enhances metadata handling and build reliability. Key features delivered: - Improve debug-mode placeholder URL for video previews: In VTFloatingInspector, replaced a hardcoded IP with a generic dummy URL for clearer debug output without changing functionality. (Commit 842a036b365db5200a030dcc6c812d66c9e48b3d) Major bugs fixed: - Prevent nextPartInstance invalidation on segment deletion: Added ensureNextPartInstanceIsNotDeleted guard; resets nextPartInstance to null if the referenced Segment is removed. (Commit b1045f992d975f747abe038047c0c0912ab88598) - Mos-Connection upgrade to fix ExternalMetadata.MosPayload passing for string content: Upgraded to mos-connection v4.2.2; changes confined to yarn.lock across packages. (Commit d4998939b463de518c7e12f32462cb77b6a40975) Overall impact and accomplishments: - Stability: Reduced risk of stale playback state and metadata misalignment, improving reliability in production workflows. - Maintainability: Dependency upgrade and clearer debugging artifacts reduce future maintenance burden. Technologies/skills demonstrated: - Dependency management and lockfile governance (yarn.lock) - TypeScript/JavaScript code health and defensive state handling (nextPartInstance) - Debug-oriented UI improvements without changing core behavior
