--------------------------------------------
Summary: Divert with incorrect filter causes startup failure
Key: ARTEMIS-5252
URL: https://issues.apache.org/jira/browse/ARTEMIS-5252
Project: ActiveMQ Artemis
Issue Type: Bug
Components: Broker
Affects Versions: 2.39.0
Environment: ActiveMQ Artemis 2.38,0 - 2.39.0 Linux / Windows
Reporter: Aleksandr Milovidov
Attachments: artemis_divert_with_incorrect_filter.log
When broker.xml contains a divert with an incorrect filter, ActiveMQ Artemis
fails to start.
Expected behavior:
If the divert was created before, keep previous divert settings and start.
If the divert was absent, skip creating the divert and start.
For example, if invalid filter is specified in the queue configuration, it does
not lead to a non-operating state of the server. A queue with an incorrect
filter is not deployed or not changed.
Also when we have a primary-backup cluster with replication, if someone
accidentally deployed incorrect divert configuration to both servers, it leads
to unavailability of the entire cluster after restart of the primary server.
Backup broker tries to become a live server but cannot start because of the
incorrect configuration.
Steps to reproduce:
1. Create a broker instance. Add to broker.xml:
{code:java}
<addresses>
<address name="test-source">
<anycast/>
</address>
<address name="test-destination">
<anycast>
<queue name="test-destination"/>
</anycast>
</address>
</addresses>
<diverts>
<divert name="divert-test">
<address>test-source</address>
<forwarding-address>test-destination</forwarding-address>
<exclusive>false</exclusive>
<filter string="key='value'"/>
</divert>
</diverts>
{code}
2. Change filter string to something incorrect which does not break xml syntax.
For example {{"(key='value'"}}
When reloading configuration, broker logs an error and continues to work:
{code:java}
ERROR [org.apache.activemq.artemis.core.server] AMQ224006: Invalid filter:
(key='value'
ERROR [org.apache.activemq.artemis.core.server] AMQ224069: Change detected in
broker configuration file, but reload failed
org.apache.activemq.artemis.api.core.ActiveMQInvalidFilterExpressionException:
AMQ229020: Invalid filter: (key='value'{code}
When restarting the broker, it logs:
{code:java}
ERROR [org.apache.activemq.artemis.core.server] AMQ224006: Invalid filter:
(key='value'
ERROR [org.apache.activemq.artemis.core.server] AMQ224000: Failure in
initialisation
{code}
