--------------------------------------
> Great! The patch looks very good!
Thanks!
> I will apply it in my environment, test it, and then commit it. The
> 'blockOnConnectionLoss' feature is OK, what is your use case? Just one
> remark:
Our application caches query results that we know to be stable. If some nodes
in the result set of such a query are not yet in the Jackrabbit caches and the
connection is lost, then they are skipped in the NodeIterator for the queries
result. I.e., our caches could get out-of-sync when the connection is lost,
which would require a restart. Blocking within Jackrabbit solves this
transparently, and this patch makes a first attempt at that. Currently one
statement/changelog fails before blocking, i.e. that statement/changelog is
lost, so with very bad luck our caches could still get out of sync. I'm still
thinking on how to block on this first statement/changelog in an elegant way.
Of course, we get a lot of contention, but that would - in theory be resolved -
when the connection comes up again.
> Currently TRIALS is 2, that means giving up after at most 1 second. I think

Yes, 10 is fine.

> Since bundled db pm doesn't inherited from database pm, it can't reconnect
> once database is bounced. it would be nice to add this feature.
