This is a real world example from our middleware.
https://github.com/cybozu-go/cmd/blob/master/http.go#L122-L132
It uses the context in the request to propagate a unique ID.
Please see also my announcement of the package here :-)

Here is an example:
https://play.golang.org/p/3mFS_7-mM8
You have two wrapper handlers (logIt and authIt). authIt, authenticates
every handler you want to authenticate. For simplicity it takes a user id
from a url and checks roles.
logIt is another wrapper handler, that logs every handler and it

Daniel, fwiw I couldn't get govendor list to work in my environment.
Sam, thanks a lot of that snippet. I also had some trouble running that,
but I was able to reverse engineer the important parts out to generate a
one-liner that worked for me.
go list -f '{{ range .Imports }}{{printf "\t%q -> %
Francis,
And, of course,
keyVals := make([]string, b.N*10)
// ...
for _, key := range keyVals {
setTwo(s, key)
}
should be
keyVals := make([]string, b.N)
// ...
for _, key := range keyVals {
setTwo(s, key)
}
or
s /b.N*10/b.N/g

In your original example, if you don't cast, it works.

Francis,
First, fix any bugs.
For example, "The benchmark function must run the target code b.N times."
https://golang.org/pkg/testing/
Therefore,
keyVals := make([]string, b.N*10)
// ...
for _, key := range keyVals {
setOne(s, key)
}
should be
keyVals := make([]string, b.N)
// ...
If I understand correctly using Context will allow "middleware" to pass
data into the handler? Can someone provide a simple example please.

thanks a lot !! It is very much appreciated.
The for loop is *very* clever.

Hi,
Does anyone know of a tool that can analyze dependencies and print a graph,
specifically as it relates to golang vendor'd libraries. I'm using 1.7 and
most tools don't seem to be able to produce results on a project that is
using vendor'd dependencies.
Tools I've tried:

Hi,
I took the liberty of creating what I think you're trying to achieve in the
go playground so I could test: https://play.golang.org/p/IgtSUNLakJ
Are you expecting the output of the two goroutines to be run in parallel so
you get the output 1 2 3 4 5 6?
Cheers

I looked at the C version, and it looks like it actually uses the TCL

I don't know the answer but if I were you, I would start from looking at
Windows applications written in Go and see how they have done.
For instance, the package https://github.com/lxn/walk has implemented lots
of Windows GUI stuff. It would probably provide the information you are
looking for.

Not sure exactly how to describe this issue or the right words to use when
talking about some of the concepts. Here's a best effort.
Given a type T that implements interfaces A1 and A2, T is an acceptable
input for any function that requires an A1 or A2 as input. Given A1 and A2
are identical in d
You could close(done). It doesn't block, thus you won't have to allocate a
buffer.
chan struct{} would take even less space and WaitGroup seems unnecessary in

I dig into the repo you mentioned, TBHonnest, im not that wise, and it
remains unclear.
For the few i know, select is the approach to take, but the API is unclear.
Not sure if it s possible to come up with something as straight as

`glide update` or a install should do the job, yes.
If that does not `mv vendor _vendor && glide install` to figure out if

Hi,
Test() never actually dereference the C string (now dangling) pointer after
C.free. And even if it did, it is unlikely that the C.free() resulted in
the memory page your string resided on was unmapped. Segfaults only happen
if you access unmapped memory.

Nevermind, looks like it is undefined behavior here.

I was expecting it to segfault after deallocating CString. How does it work
