Summary

This chapter discussed the intricacies of thread safety and concurrency within the STL. We started by distinguishing between concurrency and thread safety, underscoring that while related, each serves a distinct purpose. Our journey began with a foundational understanding of thread safety as a pillar for stable concurrency and how the lack thereof can lead to unpredictable software behavior. We examined the interplay between these concepts, addressing the challenges and highlighting the rewards of concurrent programming when thread safety is maintained.

We looked into the thread-safe nature of STL containers and algorithms, dissecting race conditions and the techniques to anticipate and guard against them. The chapter provided detailed insights into the behaviors of various STL containers under multi-threaded scenarios, from std::vector to std::list and associative to unordered containers. We also uncovered the concurrency aspects of container adaptors, asserting that knowledge...
