Subject [jira] Commented: (JCR-1563) Data Store: UTFDataFormatException when using large minRecordLength
Date Wed, 30 Apr 2008 08:38:55 GMT

    [ https://issues.apache.org/jira/browse/JCR-1563?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12593260#action_12593260
] 

Thomas Mueller commented on JCR-1563:
-------------------------------------

That's true, it was a mistake to use writeUTF. I can try to change it to write the raw bytes
in BundleBinding. Data using the new format will have the prefix '-3' (so far we have '-1'
and '-2'). I will introduce constants for those magic numbers. However this change is more
complex than simply capping minRecordLength to 32000.

> If using a value larger than 33000 for minRecordLength, and then trying to store a value
with 33000 bytes, the following exception is thrown: UTFDataFormatException. The reason is
that values are serialized using DataOutputStream.writeUTF. There is size limitation of 65
K when using this method. Small entries are hex encoded, and there is a prefix, so the limitation
for minRecordLength should be 32000.
> This is a problem for both FileDataStore and DbDataStore.
