This PR switches the Nomad repository from using govendor to Go modules for managing dependencies. Aspects of the Nomad workflow remain pretty much the same. The usual Makefile targets should continue to work as they always did. The API submodule simply defers to the parent Nomad version on the repository, keeping the semantics of API versioning that currently exists.
circbuf
This repository provides the circbuf package. This provides a Buffer object
which is a circular (or ring) buffer. It has a fixed size, but can be written
to infinitely. Only the last size bytes are ever retained. The buffer implements
the io.Writer interface.
Documentation
Full documentation can be found on Godoc
Usage
The circbuf package is very easy to use:
buf, _ := NewBuffer(6)
buf.Write([]byte("hello world"))
if string(buf.Bytes()) != " world" {
panic("should only have last 6 bytes!")
}
