Re: [jboss-as7-dev] Update to deferred resolve and start/stop

Folks, I rebased the as2777 <https://github.com/tdiesler/jboss-as/tree/as2777> branch on the current as3694 <https://github.com/tdiesler/jboss-as/tree/as3694> approach. This integrates with the CLI and you can do <deployment name="simple.war" runtime-name="simple.war"> <content sha1="be6f7ba1ceaa2028c86d080648e1467904999f8e"/> <properties> <property name="start.policy" value="deferred"/> </properties> </deployment> [tdiesler@tdvaio jboss-as-7.2.0.Alpha1-SNAPSHOT]$ bin/jboss-cli.sh --connect [standalone@localhost:9999 /] start simple.war [standalone@localhost:9999 /] stop simple.war on the server you should see 08:56:30,002 INFO [org.jboss.web] (MSC service thread 1-2) JBAS018210: Register web context: /simple 08:57:16,533 INFO [org.jboss.web] (MSC service thread 1-3) JBAS018224: Unregister web context: /simple The current implementation sets the initial mode of the CONFIGURE_MODULE to NEVER for start.policy=deferred The start/stop operations toggle the mode of the INSTALL phase service between ACTIVE/NEVER. The CLEANUP phase is currently a problem on repeated start. You'll see Caused by: java.lang.NullPointerException atorg.jboss.as.ejb3.deployment.processors.merging.AbstractMergingProcessor.deploy(AbstractMergingProcessor.java:61) at org.jboss.as.server.deployment.DeploymentUnitPhaseService.start(DeploymentUnitPhaseService.java:124) [jboss-as-server-7.2.0.Alpha1-SNAPSHOT.jar:7.2 because the EEModuleDescription is no longer attached. Stopping a deployment would not need to take the Module and associated ClassLoader down. So any datastructures needed to configure the Module can safely be cleaned up IMHO. I presume the DUPs can reasonably be fixed by moving them to the appropriate phases (see below) and by making

sure they still have the data structures attached to do yo-yo on the activate phases. Using this terminology <https://issues.jboss.org/browse/AS7-3585> STRUCTURE => STRUCTURE PARSE => PRE_INSTALL REGISTER => INSTALL => POST_INSTALL DEPENDENCIES => PRE_RESOLVE CONFIGURE_MODULE => RESOLVE FIRST_MODULE_USE => POST_RESOLVE POST_MODULE => PRE_ACTIVATE INSTALL => ACTIVATE => POST_ACTIVATE CLEANUP => CLEANUP We could stop at PRE_RESOLVE. Subsequent start would go up to and including CLEANUP. Subsequent stop would go back including PRE_ACTIVATE. Subsequent start as before. cheers --thomas -- xxxxxxxxxxxxxxxxxxxxxxxxxxxx Thomas Diesler JBoss OSGi Lead JBoss, a division of Red Hat xxxxxxxxxxxxxxxxxxxxxxxxxxxx _______________________________________________ jboss-as7-dev mailing list jboss-as7-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-as7-dev
