![]() Switch to using Go modules. This migrates our vendor.json to use Go 1.11's modules system, and replaces the vendor folder with the output of go mod vendor. The vendored code should remain basically the same; I believe some tree shaking of packages and support scripts/licenses/READMEs/etc. happened. This also fixes Travis and our Makefile to no longer use govendor. |

Yamux
Yamux (Yet another Multiplexer) is a multiplexing library for Golang. It relies on an underlying connection to provide reliability and ordering, such as TCP or Unix domain sockets, and provides stream-oriented multiplexing. It is inspired by SPDY but is not interoperable with it.
Yamux features include:
- Bi-directional streams
- Streams can be opened by either client or server
- Useful for NAT traversal
- Server-side push support
- Flow control
- Avoid starvation
- Back-pressure to prevent overwhelming a receiver
- Keep Alives
- Enables persistent connections over a load balancer
- Efficient
- Enables thousands of logical streams with low overhead
Documentation
For complete documentation, see the associated Godoc.
Specification
The full specification for Yamux is provided in the spec.md
file.
It can be used as a guide to implementors of interoperable libraries.
Usage
Using Yamux is remarkably simple:
func client() {
// Get a TCP connection
conn, err := net.Dial(...)
if err != nil {
panic(err)
}
// Setup client side of yamux
session, err := yamux.Client(conn, nil)
if err != nil {
panic(err)
}
// Open a new stream
stream, err := session.Open()
if err != nil {
panic(err)
}
// Stream implements net.Conn
stream.Write([]byte("ping"))
}
func server() {
// Accept a TCP connection
conn, err := listener.Accept()
if err != nil {
panic(err)
}
// Setup server side of yamux
session, err := yamux.Server(conn, nil)
if err != nil {
panic(err)
}
// Accept a stream
stream, err := session.Accept()
if err != nil {
panic(err)
}
// Listen for a message
buf := make([]byte, 4)
stream.Read(buf)
}
