[QPID-5850] Session names longer than 256 bytes cause errors when encoding session management objects

• Type: Bug

Description

AMQP 0-10 allows session names to be up to 2^16 bytes long; the QMF management schema for the broker however defines the name of a session object as being up to 2^8 bytes long. If a session is created with a name greater than 256 bytes, the broker cannot send out management objects for it i.e. periodic processing fails.

Python reproducer:
from qpid.messaging import *
session = Connection.establish("localhost:5672").session(name="a"*1024)
session.sync()
raw_input('Press Enter: ')

1. in a separate window use qpid-tool to view session info
   session.close()

The proposed solution is to:

• add a new field in the management session schema that can hold the full session name
• truncate the session name (if needed) when copied to the existing field
