Signed-off-by: TomSweeneyRedHat <tsweeney@redhat.com> Vendors in fsouza/docker-client, docker/docker and a few more related. Of particular note, changes to the TweakCapabilities() function from docker/docker along with the parse.IDMappingOptions() function from Buildah. Please pay particular attention to the related changes in the call from libpod to those functions during the review. Passes baseline tests.

// ContainerAttach attaches a connection to a container in the server.
|
|
// It returns a types.HijackedConnection with the hijacked connection
|
|
// and the a reader to get output. It's up to the called to close
|
|
// the hijacked connection by calling types.HijackedResponse.Close.
|
|
//
|
|
// The stream format on the response will be in one of two formats:
|
|
//
|
|
// If the container is using a TTY, there is only a single stream (stdout), and
|
|
// data is copied directly from the container output stream, no extra
|
|
// multiplexing or headers.
|
|
//
|
|
// If the container is *not* using a TTY, streams for stdout and stderr are
|
|
// multiplexed.
|
|
// The format of the multiplexed stream is as follows:
|
|
//
|
|
// [8]byte{STREAM_TYPE, 0, 0, 0, SIZE1, SIZE2, SIZE3, SIZE4}[]byte{OUTPUT}
|
|
//
|
|
// STREAM_TYPE can be 1 for stdout and 2 for stderr
|
|
//
|
|
// SIZE1, SIZE2, SIZE3, and SIZE4 are four bytes of uint32 encoded as big endian.
|
|
// This is the size of OUTPUT.
|
|
//
|
|
// You can use github.com/docker/docker/pkg/stdcopy.StdCopy to demultiplex this
|
|
// stream.
