[go-nuts] [NEWBIE] syncmap - how to use it correctly
Please explain me( I dont understand why syncmap - not sync If i try Load/Store from multiple goroutins - i have vary values with same key in syncmap If i try lock with mutex- all ok. But is syncmap not thread safe by default? Locked version of function: https://github.com/recoilme/slowpoke/blob/master/channel/main.go#L497 And async test: https://github.com/recoilme/slowpoke/blob/master/channel/main_test.go#L100 If i remove lock mutex from load/store of syncmap - test will pass or fail - and i will have muliple values with same key.
