I expect that this is so that the use
In your tests in the round-trippers you do change the requests, as far as i
can see.

I haven’t written anything like that, I’m merely offering a suggestion on why
the docs say not to do it.

hello, is there any replacement for `fork` syscall in Golang?
I've found:
- exec.Command
- syscall.ForkExec
but `exec.Command` can only execute a out side command.
syscall.ForkExec is needless, because what I need is `fork` only.
just like the C-way, fork, and return pid, then I entry differen

Note that fork() has been invented at the time when no threads were
used at all, and a process had always had just a single thread of
execution in it, and hence forking it was safe. With Go,

Learn about error handling and concurrent state in the latest release of
Get Programming with Go, available from Manning Books.
The first draft is complete. If you have any feedback, now’s the time to
get it in, as we are currently editing the book before it goes to
production.

While the garbage collector may point to this, and I’ve previously argued
about data centers stepping on other applications’ feet, my understanding
is the stated goal is systems programming.

the answer is hidden in the spec, i believe (it's not easy to parse,
so i suggest reading the whole thing):
"The right operand in a shift expression must have unsigned integer
type or be an untyped constant representableby a value of type uint.
If the left operand of a non-constant shift expressio

Hi
Total newbie question but I ave go installed and all the basic hello world
example are working fine.
However when I use go get to get a remote folder it will not create the
folders.
So I'm doing
go get github.com/golang/example/hello
and get this
cd .; git clone https://github.com/golang

Ok Basically I reinstalled Git and allowed some more functionality in the
windows cmd terminal. Seems to work now.

Hi Matthew,
First of all, thanks for looking at the free chapters and providing
feedback.
I think I should reword the paragraph about the data centre, because there
is what Go was initially announced as, and then there is the niche that it
now occupies -- the later being predominately network ser

Golang gurus,
I'm currently trying to modularize my project with the help of Golang
plugin, and I come across this dependency vendoring dilemma.
Let's say we have a project layout:
- Two different projects in separate repo: `Host` and `Guest`
- `Host` depends on package `pkgA`
- `Guest

I just made a few mods to the stringer tool to generate a function that
converts a string back to the const int type, e.g., for this const int type:
// SignalType provides standard signals -- can extend by starting at iota +
last signal here
type SignalType int64
