Query: A Study of Real-World Data Races in Golang   The concurrent programming literature is rich with tools and techniques for
data race detection. Less, however, has been known about real-world,
industry-scale deployment, experience, and insights about data races. Golang
(Go for short) is a modern programming language that makes concurrency a
first-class citizen. Go offers both message passing and shared memory for
communicating among concurrent threads. Go is gaining popularity in modern
microservice-based systems. Data races in Go stand in the face of its emerging
popularity.
  In this paper, using our industrial codebase as an example, we demonstrate
that Go developers embrace concurrency and show how the abundance of
concurrency alongside language idioms and nuances make Go programs highly
susceptible to data races. Google's Go distribution ships with a built-in
dynamic data race detector based on ThreadSanitizer. However, dynamic race
detectors pose scalability and flakiness challenges; we discuss various
software engineering trade-offs to make this detector work effectively at
scale. We have deployed this detector in Uber's 46 million lines of Go codebase
hosting 2100 distinct microservices, found over 2000 data races, and fixed over
1000 data races, spanning 790 distinct code patches submitted by 210 unique
developers over a six-month period. Based on a detailed investigation of these
data race patterns in Go, we make seven high-level observations relating to the
complex interplay between the Go language paradigm and data races.
