In stream-based programming, data sources are abstracted as a stream of values that can be manipulated via callback functions, and at Uber, our mobile apps leverage the strengths of this programming model. Even though this provides a powerful and expressive paradigm for handling asynchronous data sources in interactive software, high-level stream abstractions can also make it difficult for developers to reason about control and data-flow relationships in their programs.

In this talk, I will present our experiences with mitigating the bugs arising out of stream-based programming. Firstly, I will present the design and implementation of a type-based approach that can statically prove the thread-safety of UI accesses in stream-based software and will report our experience applying the checker to two Uber apps, where it currently runs on every code change and blocks changes that introduce potential threading bugs. Secondly, I will describe our efforts in addressing concerns pertaining to RxJava back-pressure and will share our best practices for negating it.
