Subject [jira] [Commented] (PROTON-1618) Give unambiguous indication when server listen operation succeeds or fails
Date Thu, 12 Oct 2017 02:14:00 GMT

    [ https://issues.apache.org/jira/browse/PROTON-1618?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16201339#comment-16201339

ASF subversion and git services commented on PROTON-1618:

Commit 31d5ba096aa850e49b0f2475a3c1ef9f171f9a3c in qpid-proton's branch refs/heads/master
from [~aconway]
[ https://git-wip-us.apache.org/repos/asf?p=qpid-proton.git;h=31d5ba0 ]

PROTON-1618: c++ container: unambiguous listen success/fail indicator

Added listener_handler::on_open() to indicate a successful listen.

After a call to container::listen():
- on success, call listener_handler::on_open() before any call to listener_handler::on_accept()
- on failure, call listener_handler::on_error() followed by listener_handler::on_close()

An application can tell from the first event received (on_open() vs. on_close()) if the
listen call succeeded or failed.

> The C proactor API provides events to indicate when an async listen operation has succeeded
or failed, but the semantics are a little unclear. The C++ API lacks the required events.
> Simplify & clarify the C API, and add the missing events in C++.
