-------------------------------
Summary: KahaDB checkpoint needs to fail fast in the event of
journal write failure
Key: AMQ-6815
URL: https://issues.apache.org/jira/browse/AMQ-6815
Project: ActiveMQ
Issue Type: Bug
Components: KahaDB
Affects Versions: 5.15.0
Reporter: Gary Tully
Assignee: Gary Tully
Fix For: 5.16.0
KahaDB checkpoint does some async updated to the journal and syncs to the
index. However the async journal updates can error out and not get reported
leading to the index metadata being stale. This can lead to reading an invalid
location on restart which may result in full recovery of the index.
Any exception from the async store needs to cause the checkpoint to fail.
In addition, on reading a corrupt location, we can do a sanity check to avoid a
potential OOM by validating the size before allocation.
