> I've found a few memory leaks in the Openwire code when running the unit tests for our
library. I'll report the first few now (the ones I think I've figured out), and I'll add info
on further leaks in separate comments.
> First possible leak:
> ==22866== 1728 (864 direct, 864 indirect) bytes in 12 blocks are definitely lost in loss
record 25 of 40
> ==22866==    at 0x1B90939A: operator new(unsigned) (vg_replace_malloc.c:132)
> ==22866==    by 0x81943CA: activemq::connector::openwire::OpenWireConnector::createConsumerInfo(cms::Destination
const*, activemq::connector::SessionInfo*) (OpenWireConnector.cpp:621)
> ==22866==    by 0x81994FD: activemq::connector::openwire::OpenWireConnector::createConsumer(cms::Destination
const*, activemq::connector::SessionInfo*, std::string const&, bool) (OpenWireConnector.cpp:382)
> ==22866==    by 0x8148B89: activemq::core::ActiveMQSession::createConsumer(cms::Destination
const*, std::string const&, bool) (ActiveMQSession.cpp:236)
> ==22866==    by 0x8146CAB: activemq::core::ActiveMQSession::createConsumer(cms::Destination
const*, std::string const&) (ActiveMQSession.cpp:208)
> OpenWireConnector::createConsumerInfo allocates a commands::ConsumerInfo which is returned
to OpenWireConnector::createConsumer which does a few things with it, but doesn't delete it
if the member function returns normally.
> Next possible leak:
> ==22866== 1232 (440 direct, 792 indirect) bytes in 11 blocks are definitely lost in loss
record 27 of 40
> ==22866==    at 0x1B90939A: operator new(unsigned) (vg_replace_malloc.c:132)
> ==22866==    by 0x81989F7: activemq::connector::openwire::OpenWireConnector::createProducer(cms::Destination
const*, activemq::connector::SessionInfo*) (OpenWireConnector.cpp:680)
> ==22866==    by 0x8149324: activemq::core::ActiveMQSession::createProducer(cms::Destination
const*) (ActiveMQSession.cpp:309)
> OpenWireConnector::createProducer allocates a OpenWireProducerInfo which isn't deleted
if the member function returns normally.
