Subject [jira] [Commented] (PROTON-1226) Handler not set on inbound connection
Date Mon, 06 Jun 2016 14:31:20 GMT

    [ https://issues.apache.org/jira/browse/PROTON-1226?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15316554#comment-15316554

Alan Conway commented on PROTON-1226:
-------------------------------------

 Approved for 0.13.0. Fixes a regression in the container/reactor implementation (my bad,
implemented new listener interface without fully understanding the C reactor/handler relationship),
and fixes it in the right place with no impact on connection_engine based container implementations.

> Historically, the handler was always specified before the connection was created so that
the PN_CONNECTION_INIT could go to the correct handler, whereas the rest of the connection
options could only be applied later, after creation.
> For inbound connections, the handler was set on the listener (pn_reactor_acceptor())
and the reactor set it for the accepted connections.
> History has changed.  Nobody processes PN_CONNECTION_INIT except the global handler,
so deferred setting of the handler is probably OK, allowing the handler to be set at the same
time as the other non-transport options.
> Alternatively, the caller of on_accept() must separately apply the handler (which might
change per connection on a listener) to make the new listen_handler interface work as intended.
