Alan Conway closed PROTON-1461. ------------------------------- Resolution: Cannot Reproduce Tried to reproduce this by applying this patch to the C sender example {code} modified examples/c/send.c @@ -119,7 +119,7 @@ static bool handle(app_data_t* app, pn_event_t* event) { pn_bytes_t msgbuf = encode_message(app); pn_link_send(sender, msgbuf.start, msgbuf.size); } - pn_link_advance(sender); + pn_delivery_settle(pn_link_current(sender)); /* Pre settled */ } break; } {code} I tested using the direct.c example server as follows: {code} ./direct "" amqp examples 0& sleep 1; ./send "" amqp examples 10000000000 {code} Both `send` and `direct` process grows quickly to about 370M but then stop growing while messages continue to flow. I think this is normal allocation up to max-frame-size limits by proton. I got exactly the same results with the unmodified send.c example which sends unsettled messages. Please re-open if the problem still exits and my reproducer is missing the point. > [c++] Proton C++ client silently retains presettled messages > ------------------------------------------------------------ > > Key: PROTON-1461 > URL: https://issues.apache.org/jira/browse/PROTON-1461 > Project: Qpid Proton > Issue Type: Bug > Components: cpp-binding > Affects Versions: 0.17.0 > Environment: Fedora 25 > Test message source: Qpid Dispatch Router with address that has > 'distributionMode: multicast' > Test client: example simple_recv.cpp > Reporter: Chuck Rolke > Assignee: Alan Conway > Fix For: proton-c-0.18.0 > > > With distributionMode 'multicast' the router sends messages presettled. In > this mode the simple_recv program memory grows without bound until OOM. > Switching the router to use distribution mode 'closest' causes the router to > send messages unsettled. In this mode the same simple_recv client sends back > a disposition and program memory use is normal. > A brokered connection, like to Apache Artemis, behaves normally with > unsettled messages and dispositions for each. > For comparison example program proton-0.18.0/examples/python/simple_recv.py > receives router multicast presettled messages and experiences no memory > growth. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@qpid.apache.org For additional commands, e-mail: dev-h...@qpid.apache.org
