Re: [infinispan-dev] Set of keys modified in tx

Manik,
Recall our conversation regarding adding a set of modified keys to
tx context. You said how we can have "this set of keys updated by
the TxInterceptor after a in-tx-scope completion of every write
command".
It seems that the best way to collect these keys is to add them in
TxInterceptor#enlistWriteAndInvokeNext right where we add
modifications to xaAdapter. And also the easiest way to lookup
modified keys seems to be from ctx#getLookedUpEntries(). Traverse
entries, get keys and copy them into a set in TransactionXaAdapter.
Hmm, I wonder if this is all a lot of hassle for an early unlock.
Perhaps it does make sense - as discussed on a separate email thread -
to just stipulate that any explicit locks acquired using lock() from
within a TX get released when the TX completes. Much easier for all
involved.
WDYT?
