I will take a look at your suggestions asap. I am at SLAC from half an
For your question:
Normally an XrdClientPhyConnection has not to know the
XrdClientLogConnection to dispatch the message to. This task is done by
the InputBuffer which buffers the pending responses and makes the
calling threads wait for a message for the streamid they specified. This
is due to the protocol structure, which specifies a response for every
request. If a response does not come, this is treated as a timeout error
This is for normal processing, and does not apply for unsolicited
responses, which follow another path, and are dispatched asynchronously
to the instances of XrdClient which are using that
XrdClientPhyConnection. But, for now, this is not the case.
