Worked on the goauthentik/authentik repository to enhance the stability and reliability of the Outpost API by addressing a critical concurrency issue in websocket event delivery. Focused on backend development using Go, the work involved introducing a mutex to serialize all websocket write operations within the APIController, effectively preventing panics caused by concurrent WriteMessage and WriteJSON calls. This targeted concurrency control followed gorilla/websocket best practices and resulted in a localized, low-risk change that did not alter the API surface. The fix improved system resilience, ensuring more reliable real-time event delivery and a smoother experience for clients relying on websocket connections.
