What I really would like to see is a deployer which takes cache metadata (@CacheConfig) and creates a cache based on that. Which we then inject into the container using @Inject with component scope. That would require the container to be a MC component as well though. See embedded ejb deployers.

[Design of JBoss jBPM] - postgresql enterprise tests broken (and repaired)

by alex.guizar＠jboss.com

I thought I'd post this note before someone went ahead and excluded the tests. When I upgraded the postgresql driver to 8.3 (to get the XA data source) I had to remove the classifier to match up the repository layout. The driver file name changed and the installer no longer packaged it. I did not encounter the problem locally because an earlier test had left behind another copy of the driver.

[Design of EJB 3.0] - Bringing in ejb3-cache

by ALRubinger

Recent work in SimpleStatefulCache has uncovered a few issues: * https://jira.jboss.org/jira/browse/EJBTHREE-1551 * https://jira.jboss.org/jira/browse/EJBTHREE-1549 (Resolved) My tests for 1549 are imperfect as they put Thread.sleep() into the client, resulting in: * Long execution time * Assumption that background work will have completed in the time allotted This has to be fixed. The best way to do this would be to extract out portions of SimpleStatefulCache such that they may be overridden with some locking introduced (@see org.jboss.ejb3.core.test.ejbthree1549.ForcePassivationCache.BlockingPassivationTask.block()). And while we're at it, the cache impls should really conform to the Cache SPI as dictated by the ejb3-cache project. Currently they do not. I'm working on the following: * Move / Copy / Something to put SimpleStatefulCache into ejb3-cache. Currently I can't have this implementation conform to both the legacy StatefulCache and new Cache SPIs because they're incompatible. * Do the extraction and fix the tests as outlined above * Add new internal callback mechanisms for things like "prePassivate", "passivationStarted", "passivationCompleted". Part of the contract of the cache impl will be to implement these callbacks (thus allowing us to do whatever blocking/locking or get notification in tests). * Move StatefulContainer to the new Cache SPI * WTF was I thinking with this horrid CacheFactory-per-impl design? Should better be a configurable factory capable of creating any N Caches. Ditto for the PersistenceManagerFactories. I'll have to change up the relevant jboss-beans.xml to fix this as well. Anything else we want to get in there? I'm unsure of what to do with the TreeCache impl here, because the second I move StatefulContainer to rely upon the new Cache SPI, that'll break. For now I'm starting with the elements that won't break everything. I'll have to coordinate/schedule API changes w/ Brian.

[Design of EJB 3.0] - Re: Pluggable @EJB Resolvers

by ALRubinger

I hadn't considered nested deployments, which is why we need DeploymentUnit. If JBossMetaData had a parent reference this might be a different story, but the reason I asked was to avoid the dependency on the Deployers SPI. I mentioned ClassLoader for the case that we'd need to construct Class objects from metadata in order to check assignability/equality of bean interfaces.

[Design of JBoss jBPM] - concurrency tests cannot be made to work reliably against hs

by alex.guizar＠jboss.com

I am excluding the following tests from the hsqldb build: * JBPM1072Test * JBPM938Test * JobExecutorDbTest Because hsqldb does not support isolation beyond READ_UNCOMMITTED, it allows objects to be read in inconsistent states and cause unpredictable exceptions.
