检测进口包裹中的比赛状况

Question

I have package where I write a golang code. I have a fear that program works incorrecly because it outputs different results from time to time. Probably it's due to race condtions. So I run multiple times:

go run -race myprogram

But I didn't got any warning or errros.

Probably, errors are in another package I imported. As I understand, -race flag doesn't detect them. If so, how can I do it (detect race condtion which occurs not in my code but in package I imported and I use in my code)?

Answer 1

The race condition detection is false negative rather than false positive. This means that it detects race at any time when it has just happened - when a program tries to read or write a shared value at the same time. The bottom line is the -race flag works not at 100% cases.
