That err returned from ReadAll. I cannot see how that can possibly fail.
You need a more vivid imagination. The server might crash, the network might
fail, a firewall in between might reboot, and so on. Any issue along the path
might result in a timeout, short read (server said “content-lenght: 42” only
sent five bytes), or other errors.

Re: [go-nuts] ioutil.ReadAll()
For example: https://play.golang.org/p/ycoR-jU48J9 The only read error it ignores is io.EOF (which makes complete sense, when you think about it), everything else get passed up.

[go-nuts] ioutil.ReadAll()
Hi, I have a hard time imagining when https://golang.org/pkg/io/ioutil/#ReadAll would produce err != nil. The documentation doesn't tell either. It would help when writing unittests for code that use ioutil.ReadAll(). // Patrik -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
