[jira] [Commented] (QPID-7847) qmf.client.BrokerAgent does not
provide reconnect support
[ https://issues.apache.org/jira/browse/QPID-7847?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16076760#comment-16076760 ]
ASF subversion and git services commented on QPID-7847:
-------------------------------------------------------
Commit 0ffa89e177346e68bdeb5a24b9f25190c983bd34 in qpid-cpp's branch refs/heads/master from [~aconway]
[ https://git-wip-us.apache.org/repos/asf?p=qpid-cpp.git;h=0ffa89e ]
QPID-7847: qmf.client.BrokerAgent does not provide reconnect support
Provided via BrokerAgent.connect(), for example:
BrokerAgent.connect(self.server.addr, reconnect_delays=ReconnectDelays(.125, 1, True)
After a connection failure this will try to reconnect with the following delays (seconds)
0, .125, .25, .5, 1, 1, 1, 1 ...
You can use any iterable as the reconnect_delays, ReconnectDelays provides a convenience
to generate an exponential (binary) backoff between two values, followed by a
fixed (or unlimited) repeat of the final value.

> Key: QPID-7847
> URL: https://issues.apache.org/jira/browse/QPID-7847
> Project: Qpid
> Issue Type: Bug
> Components: QMF
> Reporter: Alan Conway
> Assignee: Alan Conway
>
> Moved from PROTON-1511
> The BrokerAgent is provided by this diff: https://reviews.apache.org/r/52280/diff/3#0 Here is how to reproduce:
> 1. Instantiate a BrokerAgent connecting to a qpidd broker
> 2. Do something with the connected BrokerAgent object to show that it's working
> 3. kill qpidd with `pkill -9 -f qpidd`
> 4. start qpidd up again
> 5. Try to do step 2 again
> 6. Receive a traceback indicating the BrokerAgent is disconnected
> My code handles reconnect support for the connection, but it's not prepared to also handle reconnect support for the BrokerAgent connection. I would like that connection to have a reconnect support option added so I can call it like:
> BrokerAgent(**existing_options, reconnect=True)
> Having reconnect default to True is also fine w/ me. I think users may still want the option to set it also.
