From 7f13a9cf3a1673c42868192a85a60f7614c9a85f Mon Sep 17 00:00:00 2001 From: Solomon Hykes Date: Wed, 13 Mar 2013 00:29:40 -0700 Subject: [PATCH] Merge dockerd into docker. 'docker -d' runs in daemon mode. For all other commands, docker auto-detects whether to run standalone or to remote-control the daemon --- client.go | 53 ----------------- term.go | 143 ---------------------------------------------- termios_darwin.go | 8 --- termios_linux.go | 8 --- 4 files changed, 212 deletions(-) delete mode 100644 client.go delete mode 100644 term.go delete mode 100644 termios_darwin.go delete mode 100644 termios_linux.go diff --git a/client.go b/client.go deleted file mode 100644 index 30d741f8bd..0000000000 --- a/client.go +++ /dev/null @@ -1,53 +0,0 @@ -package client - -import ( - "github.com/dotcloud/docker/future" - "github.com/dotcloud/docker/rcli" - "io" - "log" - "os" -) - -// Run docker in "simple mode": run a single command and return. -func SimpleMode(args []string) error { - var oldState *State - var err error - if IsTerminal(0) && os.Getenv("NORAW") == "" { - oldState, err = MakeRaw(0) - if err != nil { - return err - } - defer Restore(0, oldState) - } - // FIXME: we want to use unix sockets here, but net.UnixConn doesn't expose - // CloseWrite(), which we need to cleanly signal that stdin is closed without - // closing the connection. - // See http://code.google.com/p/go/issues/detail?id=3345 - conn, err := rcli.Call("tcp", "127.0.0.1:4242", args...) - if err != nil { - return err - } - receive_stdout := future.Go(func() error { - _, err := io.Copy(os.Stdout, conn) - return err - }) - send_stdin := future.Go(func() error { - _, err := io.Copy(conn, os.Stdin) - if err := conn.CloseWrite();
