-------------------------------
Resolution: Done
Transactions corrupted because sybase truncates trailing zeros
--------------------------------------------------------------
Key: JBMESSAGING-825
URL:
http://jira.jboss.com/jira/browse/JBMESSAGING-825
Project: JBoss Messaging
Issue Type: Bug
Affects Versions: 1.2.0.Beta2
Reporter: Tim Fox
Assigned To: Tim Fox
Fix For: 1.2.0.CR1
Sybase has the wonderful characteristic of truncating trailing zeros in VARBINARY
columns.
So If I set a byte array with values: 1, 2, 3, 4, 5, 0, 0, 0
Then I get back a byte array with values: 1, 2, 3, 4, 5
Xid global txids and branch qualifiers can have trailing zeros since they can become
corrupt after storing and retrieving in the database.
Solution is to introduce a flag "usingTrailingByte" on the pm config. If true
then a non zero byte will always be appended to the byte[] before storing and removed on
retrieval.
This flag should be true for sybase config and false for others.
