Subject [jira] [Created] (JCR-3592) Retry fails when updating stream
Date Tue, 07 May 2013 19:05:15 GMT
Todd Pagni created JCR-3592:
-------------------------------

             Summary: Retry fails when updating stream
                 Key: JCR-3592
                 URL: https://issues.apache.org/jira/browse/JCR-3592
             Project: Jackrabbit Content Repository
          Issue Type: Bug
          Components: jackrabbit-core
    Affects Versions: 2.5
            Reporter: Todd Pagni


DbDataStore.addRecord executes a few update statements.   We are getting deadlocks when the
update statements are executed (different issue), which cause the update statements to fail.
 When the update fails, it should be retried in RetryManager.doTry.  When the failure occurs
due to the deadlock, we do see a retry, but they retry fails for the (UPDATE DATASTORE SET
DATA=? WHERE ID=?) query because the stream has already been read. See error below: 

com.microsoft.sqlserver.jdbc.SQLServerException: The stream value is not the specified length.
The specified length was 6,985, the actual length is 0.
