Subject [jira] Created: (YOKO-286) Connection pooling doesn't account for transport constraints

Connection pooling doesn't account for transport constraints

                 Key: YOKO-286
             Project: Yoko - CORBA Server
          Issue Type: Bug
          Components: orb core
    Affects Versions: 1.0-incubating-M2
            Reporter: David Jencks
             Fix For: Incubation

ClientManager combined with Connection_impl do not look at the transport_mech in a TAG_CSI_SEC_MECH_LIST
tagged component in a profile in an IOR.  As a result requests for a required EstablishTrustInClient
connection can get filled with a plan ssl connection.

The attached patch extracts the transport_mech tagged components from the IOR when a Connection_impl
is constructed and uses them to compare equality in the equal() method and perhaps more importantly
filter whether the Connection_impl is compatible with a second IOR in get_usable_profiles.

This patch solves the immediate problem we were having in geronimo but might be susceptible
to improvement.  In particular the extractTransportInfo(IOR) method only looks at one collection
of tagged components whereas get_usable_profiles appears to be looking at a sequence of collections
of tagged components.  In addition it might be possible to filter the profiles returned from
get_usable_profiles to return the compatible profiles rather than insisting that all the transport
infos of every profile match.
