that is actually sick.

how common is it for go devs to experience leaking goroutines ? id like to think go is a lot less shoot yourself in the foot here since they provide a framework for concurrency/parallelism rather than you working with the tiny pieces of it and building out the architecture yourself, but ive only needed to use goroutines once and it was a pretty problem-free experience.

It depends how much the code uses manually spawned goroutines, and how complex the lifecycle of these goroutines is… in big codebases such as kubernetes, docker, etc, it has been a problem. There have been research papers and blogs about this, but most Go developers are not aware of this issue it seems.

About as often as leaking memory in C++

F. again i have minimal experience actually ever needing it in go, but guessing this is just generally the exercise of managing the lifecycle of a goroutine well in your code? proper handling so things dont get orphaned in buffer, fire and forget woopsies, etc.

early on i do feel like go kinda advertised batteries included concurrency but i kinda wished they advertised the foot-shooting-mechanisms and gaps in the abstraction a little more. overall i prefer to have enough control to choose how to manage the lifecycle. mem leaks bum me out and kill my steam, at least from my experience with c/cpp.
