Overview

Package common implements the git pack protocol with a pluggable transport. This is a low-level package to implement new transports. Use a concrete implementation instead (e.g. http, file, ssh).

A simple example of usage can be found in the file package.

Types

type Command

type Command interface {
	// StderrPipe returns a pipe that will be connected to the command's
	// standard error when the command starts. It should not be called after
	// Start.
	StderrPipe() (io.Reader, error)
	// StdinPipe returns a pipe that will be connected to the command's
	// standard input when the command starts. It should not be called after
	// Start. The pipe should be closed when no more input is expected.
	StdinPipe() (io.WriteCloser, error)
	// StdoutPipe returns a pipe that will be connected to the command's
	// standard output when the command starts. It should not be called after
	// Start.
	StdoutPipe() (io.Reader, error)
	// Start starts the specified command. It does not wait for it to
	// complete.
	Start() error
	// Close closes the command and releases any resources used by it. It
	// will block until the command exits.
	Close() error
}

Command is used for a single command execution. This interface is modeled after exec.Cmd and ssh.Session in the standard library.

type CommandKiller

type CommandKiller interface {
	// Kill and close the session whatever the state it is. It will block until
	// the command is terminated.
	Kill() error
}

CommandKiller expands the Command interface, enabling it for being killed.

type Commander

type Commander interface {
	// Command creates a new Command for the given git command and
	// endpoint. cmd can be git-upload-pack or git-receive-pack. An
	// error should be returned if the endpoint is not supported or the
	// command cannot be created (e.g. binary does not exist, connection
	// cannot be established).
	Command(cmd string, ep *transport.Endpoint, auth transport.AuthMethod) (Command, error)
}

Commander creates Command instances. This is the main entry point for transport implementations.

type ServerCommand

type ServerCommand struct {
	Stderr io.Writer
	Stdout io.WriteCloser
	Stdin  io.Reader
}

ServerCommand is used for a single server command execution.
