Re: [infinispan-dev] JCache implementation documentation

Hi Galder, Thanks for your off-line email exchange confirming that community contributed tests of 5.3.0A's JSR-107 transactions option capability (and compliance) are welcome. Here is what we would like to contribute initially. 1. A test that 5.3.0.A can (both optimistically and pessimistically) accommodate a DIRTY_READ intolerant use-case via the JSR-107 API. Attached is sample JSR-107 PSEUDO code to drive this test (PESSIMISTIC policy). 2. A test that 5.3.0.A can accommodate a REPEATABLE_READ mandatory use-case via the JSR-107 API. (TODO=code). 3. A test that 5.3.0.A can accommodate a PHANTOM_READ intolerant use-case via the JSR-107 API. (TODO=note it is KNOWN that 5.3.0.A cannot yet accommodate this use case as TotalOrder on Infinispan does not yet provide isolation=SERIALIZABLE implementation. However, to be compliant with the JSR-107 Transactions option, an implementation must provide all isolation levels) Please consider taking a look at the attached plan for Test #1. It is very simple. A "Savings Account" is cached in Infinispan 5.3.0.A. Two transactional threads simultaneously operate (access/mutate) on the "Savings Account". Transactional Thread #2 indicates via the JSR-107 API that is is "DIRTY_READ" intolerant (by specifying isolation=READ_COMMITTED). It expects a pessimistic locking policy to be used by 5.3.0.A (i.e. to block @t=2 on its READ invoke). Therefore a challenge to 5.3.0.A's capability is to demonstrate the Thread 2 blocks @t=2. This test passes if Thread 2 blocks @t=2)

If you confirm this test is helpful, we will then provide a policy=OPTIMISTIC test for #1. Later, at the appropriate time, we would like to produce explicit tests for #2 and #3.
