[jira] Resolved: (QPID-2278) Store recovery compatibility problem
introduced by alternate-exchange fix
[ https://issues.apache.org/jira/browse/QPID-2278?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Kim van der Riet resolved QPID-2278.
------------------------------------
Resolution: Fixed
Changing the order of the encoded items such that the alternate exchange is encoded last (after the args FieldTable) means that on decode, the broker can check for remaining bytes and decode the alternate-exchange name only if the string is present.
Fixed in r.890965

> A recent checkin (r.831082) fixed a problem in which the exchange did not persist the alternate-exchange setting, and on recovery this was being lost. To fix it, an additional string was added to the Exchange::encode() and Exchange::decode() methods. However, this fix means that there is a binary incompatibility between pre- and post-fix exchange data. Attempting to recover stores from pre-fix brokers result in broker shutdown if recovery is attempted using post-fix brokers.
