You’re on Windows, right? Does any one get this and are they (you reading this) on Windows as well?

5

yes, I ran it on win10 x64 + go 1.14.

Interesting if this happening on this specific platform… so much for platform compatibility for golang if this is the case!

Can you close this: https://github.com/travisjeffery/proglog/tree/master/ServerSideServiceDiscovery and run the tests in the ServerSideServiceDiscovery directory. If they do pass, can you give me a recursive diff between your and this ServerSideServiceDiscovery directory. On Linux I’d do that with diff -r don’t know how you’d do that on Windows.

Hi again,

It still errors out in windows. However I ran the code on a linux vm, and it passed without problems…

Maybe you put a note in your book commenting that the code is proven to work only in unix like environments?

8

Yeah I’ll definitely mention it in the book. If I get a chance I’ll tinker with it on Windows as well. Or you ever find a fix I’d appreciate it.
