--------------------------------------
Summary: Crash router by deleting authServicePlugin entity through
management call
Key: DISPATCH-1477
URL: https://issues.apache.org/jira/browse/DISPATCH-1477
Project: Qpid Dispatch
Issue Type: Bug
Components: Management Agent
Affects Versions: 1.9.0
Reporter: Ernest Allen
I'm able to crash the router to which the console is connected.
Below are the step to do it through a console. It should also be possible
through qdmanage.
Steps:
* Go to the entities page
* select authServicePlugin from the list of entities on the left
* if there are no plugins listed
** click on the 'no data' item on the left
** select the Create tab at the top of the area on the right
** click the Create button at the bottom of the form
** reselect the authServicePlugin from the list
* select an authServicePlugin from the sublist
* click the Delete tab
* click the Delete button
Expected results:
The selected authServicePlugin should be deleted
Actual results:
The router to which the console is connected crashes.
Last entry from the router's log:
2019-11-09 10:04:26.052574 -0500 CONN_MGR (warning) Attribute authService of
entity authServicePlugin has been deprecated. Use host and port instead.
2019-11-09 10:04:26.052620 -0500 CONN_MGR (info) Created SASL plugin config
with name (null)
