Health Check Updates

Changes to the health system this release include improved stability, logging, documentation, and lifecycle conditions.

  • Parameter checking and error reporting - All health checks, actions, and conditions were updated to check for missing or invalid attributes and report clearer error logs.
  • Documentation - Full documentation of the health checking system is now present at /resin-doc/admin/health.xtp.
  • Lifecycle conditions - Resin can now be configured to execute health actions on startup, shutdown, and restart.
Example: Sending an email on startup in health.xml
<cluster xmlns="http://caucho.com/ns/resin"
         xmlns:health="urn:java:com.caucho.health">

  <health:SendMail>
    <to>admin@yourdomain.com</to>
    <health:OnStartup/>
  </health:SendMail>
 
</cluster>

maven/junit embedding/integration with JPA/data sources

When embedded Resin is launched inside a maven/junit task, the default behavior is to disable Resin's Alarm, which manages timeouts. To re-enable the alarm, use a '-Dcaucho.alarm-enable' on the command-line when launching Java.

The alarm is disabled in embedded cases to handle of embedded Quercus in a non-Resin container.

WebSocket draft v7

Resin's WebSocket support has been upgraded to the test v7 draft of the IETF specification.
