[jira] Created: (QPID-2456) Staged transient messages do not get
deleted from store
Staged transient messages do not get deleted from store
-------------------------------------------------------
Key: QPID-2456
URL: https://issues.apache.org/jira/browse/QPID-2456
Project: Qpid
Issue Type: Bug
Components: C++ Broker
Affects Versions: 0.6
Reporter: Gordon Sim
There are two cases here. In both, a store module must be loaded.
(a) run ./src/tests/datagen --count 1 --min-size 7000000 --max-size 7000000 | ./src/tests/sender, with no queue named test-queue defined. The message will be dropped but the staged data remains (see the log files in .qpidd/rhm/dat) and grows each time you repeat.
(b) with a transient queue created, (e.g. qpid-config add queue test-queue), dequeued staged messages are likewise not deleted (./src/tests/datagen --count 1 --min-size 7000000 --max-size 7000000 | ./src/tests/sender --send-eos 1, then ./src/tests/receiver > /dev/null and again check the growing log files)

[jira] Closed: (QPID-2456) Staged transient messages do not get

----------------------------------
Resolution: Not A Problem
The growth of BDB log files does not indicate that the messages are not being deleted. The log files are used to recover transactions in case of database failure. There should be a strategy to manage these files.
Running the scenarios above, I have seen that the database itself (messages.db) remains at approximately the size of the largest message sent. A code inspection shows that the messages are in fact deleted.
