* rpc: implement websockets with github.com/gorilla/websocket
This change makes package rpc use the github.com/gorilla/websocket
package for WebSockets instead of golang.org/x/net/websocket. The new
library is more robust and supports all WebSocket features including
continuation frames.
There are new tests for two issues with the previously-used library:
- TestWebsocketClientPing checks handling of Ping frames.
- TestWebsocketLargeCall checks whether the request size limit is
applied correctly.
* rpc: raise HTTP/WebSocket request size limit to 5MB
* rpc: remove default origin for client connections
The client used to put the local hostname into the Origin header because
the server wanted an origin to accept the connection, but that's silly:
Origin is for browsers/websites. The nobody would whitelist a particular
hostname.
Now that the server doesn't need Origin anymore, don't bother setting
one for clients. Users who need an origin can use DialWebsocket to
create a client with arbitrary origin if needed.
* vendor: put golang.org/x/net/websocket back
* rpc: don't set Origin header for empty (default) origin
* rpc: add HTTP status code to handshake error
This makes it easier to debug failing connections.
* ethstats: use github.com/gorilla/websocket
* rpc: fix lint

Gorilla WebSocket
Gorilla WebSocket is a Go implementation of the WebSocket protocol.
Documentation
Status
The Gorilla WebSocket package provides a complete and tested implementation of the WebSocket protocol. The package API is stable.
Installation
go get github.com/gorilla/websocket
Protocol Compliance
The Gorilla WebSocket package passes the server tests in the Autobahn Test Suite using the application in the examples/autobahn subdirectory.
Gorilla WebSocket compared with other packages
| github.com/gorilla | golang.org/x/net | |
|---|---|---|
| RFC 6455 Features | ||
| Passes Autobahn Test Suite | Yes | No |
| Receive fragmented message | Yes | No, see note 1 |
| Send close message | Yes | No |
| Send pings and receive pongs | Yes | No |
| Get the type of a received data message | Yes | Yes, see note 2 |
| Other Features | ||
| Compression Extensions | Experimental | No |
| Read message using io.Reader | Yes | No, see note 3 |
| Write message using io.WriteCloser | Yes | No, see note 3 |
Notes:
- Large messages are fragmented in Chrome's new WebSocket implementation.
- The application can get the type of a received data message by implementing a Codec marshal function.
- The go.net io.Reader and io.Writer operate across WebSocket frame boundaries. Read returns when the input buffer is full or a frame boundary is encountered. Each call to Write sends a single frame message. The Gorilla io.Reader and io.WriteCloser operate on a single WebSocket message.
