[infinispan-dev] TreeCache needs Flag(s) to be maintained for the duration of a batch/tx

Hi, Re: https://issues.jboss.org/browse/ISPN-841 The issue here is the fact that if you call a TreeCache operation passing flags, you want this flags to apply to all cache operations encompassing the tree cache op. Now, the thing to remember about flags is that they get cleared after each cache invocation, so we must somehow pass flags around to all methods that operate on the cache as a result of a treecache.put for example. A rudimentary way to do so would be to pass Flag... to all methods involved which is not pretty and hard to maintain. An alternative would be to have some flags thread local that gets populated on start of tree cache operation and gets cleared in the end of the operation. Although this might work, isn't this very similar to what CacheDelegate does to maintain flags except that instead of keeping them for a cache invocation, it would keep them hanging around until the end of the operation? TreeCache operations are bounded by start/stop atomic calls that are essentially calls to start/stop batches. So, it seems to me that what this is asking for is for a wider functionality to keep flags for the duration of a transaction/batch, which would most likely be solved better in core/ Thoughts? -- Galder Zamarreño Sr. Software Engineer Infinispan, JBoss Cache
