About chenyahui/AnnotatedCode
AnnotatedCode is a GitHub repository that provides detailed annotations and explanations for the source code of well-known open-source projects. It covers C/C++ projects such as libco (coroutine), Redis, muduo (network library), libevent, and sofa-pbrpc, as well as Go projects including groupcache, ratelimit (rate limiter), and go/x/time/rate. Additionally, it includes in-depth analysis of Go standard library components (e.g., sync.Cond, WaitGroup, channel, timer). The annotations are accompanied by blog posts available at cyhone.com. The repository is archived and read-only as of November 2023.
