摘要

众所周知,并发编程是一门硬学科。在过去的几年中,为了简化并发编程实践,在改进并发编程抽象、技术和工具方面取得了巨大的进步。然而,在评估开发人员在编写并发应用程序时所面临的实际问题方面却很少付出努力。在本文中,我们对StackOverflow上并发编程的前250个最受欢迎的问题进行了实证调查。我们观察到,尽管有些问题(22.94%)与实际问题有关(例如,“如何修复这个并发错误”),但大多数问题(66.23%)与基本概念有关(例如,“什么是互斥锁?”),这些问题都是由经验丰富的StackOverflow用户创建的。奇怪的是,我们没有发现任何关于如何使用并发编程技术来提高应用程序性能的问题。

A study on the most popular questions about concurrent programming
Concurrent programming is notably known as a hard discipline. Over the last few years, great strides have been made in improving concurrent programming abstractions, techniques, and tools to ease concurrent programming practice. However, little effort has been placed on assessing what are the real-world problems faced by developers when writing concurrent applications. In this paper, we describe an empirical investigation of the top-250 most popular questions about concurrent programming on StackOverflow. We observed that even though some questions (22.94%) are related to practical problems (e.g., “how to fix this concurrency bug”), most of them (66.23%) are related to basic concepts (e.g., “what is a mutex?”), which were created by well- experienced StackOverflow users. Curiously, we did not find any question about how to use concurrent programming techniques to improve application performance.
