Subject [jira] Commented: (LUCENENET-357) Mostly won't work on shared hosts / Mosso cloud etc due to 'Trust' levels
Date Wed, 21 Apr 2010 18:49:51 GMT

    [ https://issues.apache.org/jira/browse/LUCENENET-357?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12859480#action_12859480
] 

Frank West commented on LUCENENET-357:
--------------------------------------

I've checked a couple of times for anything relating to that - no dice. 
Is it even physically possible, isn't that going beyond what we have access to in a medium
trust environment?

TBH: I have no experience with this WeakReference concept, so I may be getting it all wrong.

Wouldn't it be simpler to just manage the cache in a regular fashion (expires, limits, etc),

rather than relying on these 'weak keys' - or wrap them in a container that you have access
to?

I have no problems at all with caching within my system, (apart from the time it takes regex
to remove some complex cache keys)
We just maintain lists, when they expire the GC removes them, and if the query is re-issued
it's regenerated / re-cached. Some slide, others expire in set times.
Everything is reasonable.

I don't know much/anything about WeakKeys - so perhaps I'm missing something.

However now it fails use of the 'Weak Hashtable' - any reference to a 'weak[something]' will
fail with a security exception. The issue only happens when returning sorted results.

(Rackspace cloud)
