+ a command to open/create a channel on a connection?
All I've really seen of 0-10 so far, is the amqp.0-10-preview.xml, that has
been checked in on trunk. That doesn't have a 'channel' class in it (yet?).
In 0-10 the term channel refers to the physical transport for a session,
and although at any given point a session may only be attached to a
single channel, over it's lifespan a session may be connected to
multiple channels.
AMQP assumes that channels are purely a mechanism for multiplexing a
connection, so logically when a connection is established, the whole
range of permitted channels (0 to the negotiated MAX) are ready and
available for use.
The only thing you can actually do to a channel in AMQP without a
session being attached to it is to either open or resume a session, so
at the moment at least there is no need for a channel class.

In 0-10...
A TCP connection has many channels... (same as 0-8)
A Session may have a lifetime that exceeds the lifetime of a single
connection.
A session may be attached to a (single) channel.
It may then be detached, and later re-attached to a separate channel on
the
same or a different connection.
After a Session has been detached from a channel (or after the session has
been clsed) a different session may attach to that channel.
Hope this helps,

Hi, I had another look at this code and have another question. I am not
particularly well versed yet with the 0-10 protocol, so this may just be
my
ignorance. Is 'channel' in 0-8 renamed to 'session' for 0-10, and
completely
dropped from the 0-10 protocol? Or does 0-10 have both channels and
sessions?
Reason I ask is because the stub has connection, channel and session.
Sessions are opened on channels. Connection can have many channels, but
session and channel are always tied together 1:1.
Should it be that connection can have many sessions and the session open
method is handled at the connection level?
