Does this fix #104? It seems like this will return false and nil for the error if it is not a socket.

Yeah good point... I initially return error but then wonder if it will break things so I change it to warning. I think an Error here seems okay to me? It's just we will have to change the CleanUpSocket function as well.

I vaguely recall the socket checking logic differs between linux and Windows. It might be worth double-checking.

There is already a TestSocketRegularFile which I modified a little bit that test this behavior.
The limitation is that we will have different behaviors on linux and windows... Because according golang/go#33357, windows socket file are not returning the right mode somehow... So the test will behavior a little bit different based on the two platforms.

Do we have a unit test that asserts we should return an error if the socket path exists but is not a socket file? |
