Re: [javagroups-users] Considering migrating to jboss cache from DistributedTree

Not sure what you mean here by "binding". Passing a JChannelFactoryMBean to the RuntimeConfig doesn't carry with it a requirement to pass in a TransactionManager. Think of RuntimeConfig as basically being a placeholder through which the external environment can pass in complex objects the cache may need and through which callers can get access to a few of the cache internals. > If I were to pass in a channel to CacheImpl, > whether multiplexed or not, I don't think I'll mess with > setUsingMultiplexer() and friends in the Configuration.

If you're writing your own extensions, then presumably you know how the code will be used and can guard against misuse. So, the barrier for what's considered "safe" can be a lot lower. :) > Thanks very much for the reply.

finishing JBCACHE-964 - refactoring JDBCCacheLoaderOld and any source depending on it to "migration" path

by Galder Zamarreno

Hi, JBCACHE-964 is getting close to completion. I have docu and some refactoring pending which I'd like to get some consensus on: JDBCCacheLoaderOld is a classloader that it's in the main code for legacy purpouses. As part of JBCACHE-964, I have created a migration directory that includes a classloader to transform data from 1.x to 2.x. I was talking to Manik about moving JDBCCacheLoaderOld to this migration directory, removing it from the main source directory. That means that if a customer wants to use it, they need to add jbosscache-cacheloader-migration.jar to their classpath which is fine, making the customer think twice before doing it. As part of this refactoring, AdjListJDBCCacheLoaderCompatibilityTest which relies on JDBCCacheLoaderOld would also be moved to the tests directory of the migration path (quite likely migration/tests/functional) and similar thing would occur to OldImplBenchmark (possibly to migration/tests/perf which does not exist right now) This would require a bit of refactoring but I think it's minimal and removes non trunk source/test code from the main codebase. Thoughts? -- Galder Zamarreño Sr. Software Maintenance Engineer JBoss, a division of Red Hat
