cache preload in 2.1.1; does it work?

bord Jun 2, 2008 10:10 AM

hello all, (this is jbosscache 2.1.1GA)
I have the /whatever set in my XML CacheLoaderConfiguration, yet the preloading through cacheloader is not happening at time of cache.start. I have to explicitly follow the cache.start with a call of getCacheLoaderManager().preload() using the CacheSPI object to get preloading to work.
This is not satisfactory because the loading happens after my cacheStarted listener is invoked and the latter was designed to set a flag to distinguish preloads from later loads. (So i have to do further work-arounds with this flag setting.)

When i look at the jboss 2.1.1GA code I was appalled to see the CacheImpl.internalStart performs the preloadCache when the cacheLoaderManager object is non-null, yet the latter private member is never set in the class including the injectDependencies -- latter seems to set all the other data members.

So is anyone getting cache loader preloading to work in 2.1.x?
For most part my XML cacheloader configuration is the same as what i had working in 1.4.1 release (note i skipped 2.0).
thanks
Craig

Interesting that you see this problem - there are unit tests in 2.1.1 that prove that preloading works.

Could you tell me how you create and start your cache? E.g., do you retrieve a started, running cache from the DefaultCacheFactory or do you get an unstarted cache and call create() and start()?

Ugh, that's not pleasant. Our "preload" test seems to have been modified so that it does not test preloading.

Thanks for reporting this. JBCACHE-1358.

Have you tried 2.1.0 or 2.0.0?

Cheers

I had the problem in 2.1.0 and have not tried 2.0.0.

Anyway it is fixed in trunk and branch 2.1.X now. Will be releasing another CR on 2.2.0 very soon.
