QPID-5460: [linearstore] Recovery of store which contains prepared but incomplete transactions results in message loss
> [linearstore] Recovery of store which contains prepared but incomplete transactions results in message loss
> -----------------------------------------------------------------------------------------------------------
>
> Key: QPID-5460
> URL: https://issues.apache.org/jira/browse/QPID-5460
> Project: Qpid
> Issue Type: Bug
> Components: C++ Broker
> Reporter: Kim van der Riet
> Assignee: Kim van der Riet
>
> 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.
> Steps to Reproduce:
> 1. Start broker loading linearstore:
> {color:blue}{{./qpidd --load-module linearstore.so --truncate yes}}{color}
> 2. Run qpid-txtest against broker:
> {color:blue}{{./qpid-txtest --messages-per-tx 4 --tx-count 1000000 --total-messages 100 --size 10 --queues 5}}{color}
> 3.After several seconds of running, kill the broker:
> {color:blue}{{ps -eaf | grep qpidd}}
> {{kill -9 <pid from previous cmd>}}{color}
> 4. Restart broker and recover messages (don't use --truncate)
> {color:blue}{{./qpidd --load-module linearstore.so}}{color}
> 5. Check for lost messages using qpid-txtest:
> {color:blue}{{./qpid-txtest --messages-per-tx 4 --tx-count 1000000 --total-messages 100 --size 10 --queues 5 --check yes --init no --transfer no}}{color}
> Actual results:
> {{qpid-txtest}} reports some messages are missing.
> Expected results:
> {{qpid-txtest}} retrieves all messages.
