Description Kim van der Riet 2014-01-09 16:56:14 UTC
During recovery of the linear store, transactions that were being prepared at the time the broker stopped/crashed are not correctly recovered, and this results in these messages being lost.


Version-Release number of selected component (if applicable): Trunk


How reproducible: Easily


Steps to Reproduce:
1. Start broker loading linearstore:
./qpidd --load-module linearstore.so --truncate yes
2. Run qpid-txtest against broker:
./qpid-txtest --messages-per-tx 4 --tx-count 1000000 --total-messages 100 --size 10 --queues 5
3.After several seconds of running, kill the broker:
ps -eaf | grep qpidd
kill -9 <pid from previous cmd>
4. Restart broker and recover messages (don't use --truncate)
./qpidd --load-module linearstore.so
5. Check for lost messages using qpid-txtest:
./qpid-txtest --messages-per-tx 4 --tx-count 1000000 --total-messages 100 --size 10 --queues 5 --check yes --init no --transfer no

Actual results:
qpid-txtest reports some messages are missing.

Expected results:
qpid-txtest retrieves all messages.
