Pavel Moravec created QPID-5533: ----------------------------------- Summary: [C++ broker] Linearstore to return any empty page to EPL Key: QPID-5533 URL: https://issues.apache.org/jira/browse/QPID-5533 Project: Qpid Issue Type: Improvement Components: C++ Broker Affects Versions: 0.24 Reporter: Pavel Moravec Priority: Minor
Linear store should return to EPL _any_ empty file of a journal, not only the oldest one (once it gets emptied). As there can be corner cases where journal enqueue record sits in journal (almost) forever, while the journal gets next enqueue+dequeue records in parallel. In particular, basic scenarios cover message filters in consumers, priority queue (with message of lower priority never consumed), or tpl journal with orphaned transaction (until QPID-5531 is fixed). One particular reproducer with priority queue: qpid-config add queue testQueue --argument=x-qpid-priorities=10 --durable qpid-send -a testQueue -m 1 --priority 1 --durable=yes while true; do ./src/tests/qpid-send -a testQueue -m 5000 --priority 2 --durable=yes; ./src/tests/qpid-receive -a testQueue -m 5000 --print-content=no; qpid-stat -q; done ~/.qpidd/qls/jrnl/testQueue/ grows forever. (I am fine to close it as WONTFIX if a potential fix would be too complex, compared to the probability of the corner cases) -- This message was sent by Atlassian JIRA (v6.1.5#6160) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@qpid.apache.org For additional commands, e-mail: dev-h...@qpid.apache.org
