rpc.debugLog unexported

How can I turn on debugging in net/rpc/server.go?

There is a promising variable called `debugLog` in there. How should I toggle it?

I don't know how much it will help, but the way to toggle it is to
literally edit net/rpc/debug.go to set debugLog to true. There's no
mechanism for setting it dynamically.

Thanks for your reply. Do you regularly edit standard libs as described (and
then presumably edit them back)?

I copied /usr/lib/go-1.13/net/rpc to my project directory, then changed all
imports of "net/rpc" to "./net/rpc", and then set debugLog (in my shadow copy,
not /usr/lib/go-1.13). It got the job done but still felt wrong.

While debugging the standard library, yes, I do. But I also agree
that for this case it might be useful to have a more usable mechanism.

If that helped solve the problem then I would encourage you to file an
issue asking for a mechanism to set debugLog in a simpler way, perhaps
via the `GODEBUG` environment variable or perhaps via a function in
the net/rpc package.

Hi,

I had tried a similar approach for customizing golokia. 

Why do we need to move the imported packages code to the project directory? 
Doesn't go compile using the local copy of the imported package in GOPATH? 

What am I missing here?
