This may be better asked in a k8s forum, but I'm not aware of a good one,
and as I've never seen this anywhere but in Go applications, perhaps
someone here will know about this.
In our enterprise, we have a bunch of k8s clusters. I have a bunch of Go

I did. It fails to parse dates with two digits for the month or day.

A little while ago, I was able to write some unit tests for some code that
makes an http connection. I created a mockserver and a client using that
server. That test in that application works fine.
I'm now trying to do basically the same thing in a different application.

I don't expect this should be very difficult, go-wise, but I haven't

I am not a new programmer, but I am pretty new to golang, having only
written a couple of small applications, and that was several months ago.
I'm trying to construct an application using Cobra, using some nonstandard
conventions. Is it better to ask a question like this in an issue in the

There is nothing new here. Every programming language, framework, and tool
has had the same problem. Quality documentation and training is often the
hardest thing to produce, and is often deemphasized in budgets. It's also

Ok. I did that. https://github.com/golang/go/issues/51337 .

A while ago, I wrote a small Go app that reads things from zip files. I
tested it with various zip files (usually Java jar files), and it has
always worked perfectly fine.
Today I'm looking at another jar file. The Java "jar" command likes it
perfectly fine. I could list the contents and extr

I'm aware of the "build constraints" mechanism, which lets individual files
be only compiled on specific oses or architectures.
I am constructing an app that has a single cgo module, which is the "meat"
of the application (longest module). In my poc, the cgo header specifies a

I'm pretty new to Go (many years in other languages). I'm trying to use
cgo to use a C library we're using.
I have the following line of code, which is compiling (that's been enough
of a struggle):
status = int(C.VeProtect(C.VeObj(fpeProtect), &argsProtect))
This is failing at runtime with
32 matches
