AMQP 0-10 allowed session names to be up to 2^16 bytes long. The QMF management schema for the broker defined the name of a session object as being up to 2^8 bytes long. If a session was created with a name greater than 256 bytes, the broker could not send out management objects for the session, and periodic processing failed. Changes to the QMF management tools now support long-named sessions, which fixes the originally reported issue.

Description

A two part solution is proposed: 1. Truncate the session name when it is stored in the management object. A uuid would be prepended to the supplied session name to guarantee uniqueness. 2. Add a new field in the management schema that handles the full length name. Management tools will need to be updated to use the new field. Created attachment 912417 [details]
Adds "fullName" field and trucates existing "name" field in needed
Patch was reviewed and accepted
Created attachment 917427 [details]
Fixes problem with qpid-stat -u
Modified management schema to name new "fullName" field optional and RO. This allows then new schema to work with existing brokers.
Modified the SessionState and ManagedSession code to set the new field.

Makes new field optional and fixes qpid-tool display
Changes the new "fullName" field to optional. Addresses the qpid-tool formatting by truncating the table header separator to 256 characters.

Fixed patch
Fixed previous patch. managemnet-schema.xml is in the correct location now and patch was generated cleanly and not edited.
Patch applied upstream: http://svn.apache.org/r1611016 The long named session are fully supported by QMF management tools now, no exception is raised on the broker side.
