[jira] [Commented] (DISPATCH-1037) Listeners with http enabled are
not being shutdown after they are deleted
[ https://issues.apache.org/jira/browse/DISPATCH-1037?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16511493#comment-16511493 ]
Ganesh Murthy commented on DISPATCH-1037:
-----------------------------------------
Due to difficulty in deleting HTTP listeners via libwebsockets, we are no longer allowing delete operation on HTTP listeners
> Listeners with http enabled are not being shutdown after they are deleted

> Key: DISPATCH-1037
> URL: https://issues.apache.org/jira/browse/DISPATCH-1037
> Project: Qpid Dispatch
> Issue Type: Bug
> Components: Routing Engine
> Reporter: Fernando Giorgetti
> Assignee: Ganesh Murthy
> Priority: Major
>
> When an http enabled listener is deleted through the console, or via qdmanage ($management), it is being removed from the list of listeners (qdmanage query) but the router still listens to the related TCP port.
> In the example below I had a router with an http listener on port 5674 and a non-http listener at 5672.
> Here are the steps to demonstrate it:
> * Start the router and query listeners
>
> {code:java}
> $ qdmanage query --type listener | egrep 'name'
> "name": "listener/0.0.0.0:5672",
> "name": "listener/0.0.0.0:5674",
> {code}
>
> * Verify TCP ports being listened
>
> {code:java}
> $ netstat -anp | egrep tcp.*LISTEN.*qdrouterd
> tcp 0 0 0.0.0.0:5672 0.0.0.0:* LISTEN 2887/qdrouterd
> tcp 0 0 0.0.0.0:5674 0.0.0.0:* LISTEN 2887/qdrouterd
> {code}
>
> * Delete HTTP listener on port 5674
>
> {code:java}
> $ qdmanage delete --type listener --name 'listener/0.0.0.0:5674'
> {code}
>
> * Query listeners
>
> {code:java}
> $ qdmanage query --type listener | egrep 'name'
> "name": "listener/0.0.0.0:5672",
> {code}
>
> * Verify TCP ports being listened
>
> {code:java}
> $ netstat -anp | egrep tcp.*LISTEN.*qdrouterd
> tcp 0 0 0.0.0.0:5672 0.0.0.0:* LISTEN 2887/qdrouterd
> tcp 0 0 0.0.0.0:5674 0.0.0.0:* LISTEN 2887/qdrouterd
> {code}
>
> Note: This is only happening with http enabled listeners. Regular listeners are being shutdown properly.
