What version of Go are you using (go version)?

go version go1.7.1 windows/amd64

What operating system and processor architecture are you using (go env)?

Windows 10 Pro x64 1607

What did you do?

Follow the demo guide provided for h2i tool:

  • go get golang.org/x/net/http2/h2i
  • h2i google.com

What did you expect to see?

h2 debug log for connection to google.com. Something like this:

Connecting to google.com:443 ...
Connected to 74.125.224.41:443
Negotiated protocol "h2-14"
[FrameHeader SETTINGS len=18]
  [MAX_CONCURRENT_STREAMS = 100]
  [INITIAL_WINDOW_SIZE = 1048576]
  [MAX_FRAME_SIZE = 16384]
[FrameHeader WINDOW_UPDATE len=4]
  Window-Increment = 983041

What did you see instead?

Connecting to google.com:443 ...
Connected to 172.217.20.14:443
Negotiated protocol "h2"
The handle is invalid.

I suspect the golang.org/x/crypto/ssh/terminal package doesn't work on Windows.

Have you tried the Bash for Windows thing? Maybe it'll work there.

That didn't work also it results in some sys call error and then:

# golang.org/x/net/http2/hpack
/home/raees/go/src/golang.org/x/net/http2/hpack/huffman.go:14: undefined: sync.Pool

Um, I think you're using some ancient version of Go then. I'm not convinced you're actually using Go 1.7 as you think you are.

I've verified the version and it is go version go1.7.1 linux/amd64 and here is the error:

raees@RAEES-PROBOOK:~$ go get golang.org/x/net/http2/h2i
# cd /home/raees/go/src/golang.org/x/crypto; git submodule update --init --recursive
package golang.org/x/crypto/ssh/terminal: read |0: interrupted system call

My guess is that Microsoft WSL team has not yet implemented the system calls used by this package.

Okay, closing this bug then. I'm not sure there's anything I can do.

On a second try, it actually worked without changing anything. The output text is displayed in a wired way but the tool seems to be working fine.
