Ganesh Murthy commented on PROTON-1927:
---------------------------------------
if you called "create_receiver(conn, self.address)" twice, or
"create_sender(conn, self.address)" twice, the *second* call will not create a
new sender or receiver since the previous call already did.
For examplke
r1 = .create_receiver(conn, self.address)
r2 = .create_receiver(conn, self.address)
In the above case r1 and r2 are the same.
To create two distinct receivers you need to use the *name* parameter
r1 = .create_receiver(conn, self.address, name="r1")
r2 = .create_receiver(conn, self.address, name="r2")
In this case r1 and r2 are two distinct receivers and the link names are
distinct too.
> Python _reactor.py creates duplicate link names for senders/receivers

> Project: Qpid Proton
> Issue Type: Bug
> Components: python-binding
> Affects Versions: proton-c-0.24.0
> Reporter: Chuck Rolke
> Priority: Major
>
> From DISPATCH-1114
> Creating a sender and a receiver in the same container produces duplicate
> link names. Try python/examples/helloworld.py that executes:
> event.container.create_receiver(conn, self.address)
> event.container.create_sender(conn, self.address)
> generates the same link name for each attach:
> (M=a1b7d *1 ?3) chug@ratchet examples> PN_TRACE_FRM=1 ./helloworld.py
> ...
> [0x55a01066d9a0]:0 -> @attach(18)
