I wrote a pool of workers, where the job is to receive an integer and return that number converted to string. However I faced a fatal error: all goroutines are asleep - deadlock!
error. What am I doing wrong and how can I fix it?

I was able to replicate your issue and fix it by using a pointer to
master
instead of a normal variable.Basically just change your
NewWorker()
method to this:func (m *Master) NewWorker() { m.Workers = append(m.Workers, Worker{}) }
Here's the output the program prints after the change:
0 1 2 3 4 5 6 7 8 9 10 . . .
Reason:
Everytime you called
NewWorker()
method, you weren't appending aworker
to the same master object. That's why the slice never got populated with 3 workers, as should've been the case.本回答被题主选为最佳回答 , 对您是否有帮助呢?解决 无用评论 打赏 举报
