Subject [jira] [Commented] (PROTON-1927) Python _reactor.py creates duplicate link names for senders/receivers
Date Fri, 07 Sep 2018 09:23:00 GMT

    [ https://issues.apache.org/jira/browse/PROTON-1927?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16606882#comment-16606882

Robbie Gemmell commented on PROTON-1927:
----------------------------------------

Creating a sender and receiver link with the same name is expressly allowed by the spec, the
naming scope is directional.

I'd be more concerned with what it did if you called "create_receiver(conn, self.address)"
twice, or "create_sender(conn, self.address)" twice. The above suggests it might generate
them both the same name, which would be an issue.

> 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
> ...
