Alex Hansson enhanced connection error logging in the apple/foundationdb repository by integrating peer address information into N2_ConnectError trace events. Using C++ and leveraging network programming and error handling expertise, Alex required peer address to be passed at BindPromise construction, removing the previous setPeerAddr method to enforce correctness and consistency. All relevant call sites were updated to ensure peer address availability, aligning new logging with existing N2 error events for a unified approach. This work improved observability and streamlined debugging workflows, enabling faster root-cause analysis of network failures and contributing to more reliable operational monitoring within the codebase.
