Subject [jira] [Updated] (JCR-2960) Long values not properly stored
Date Fri, 06 May 2011 14:38:03 GMT

     [ https://issues.apache.org/jira/browse/JCR-2960?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Stefan Guggisberg updated JCR-2960:
-----------------------------------

    Description: 
When a long value assigned to a property is too big, when restarting the server the value
become 0 !! 

The test pass with versions 1.6.4 and 2.0

  was:
When a long value assigned to a property is too large,  the value is correctly read until
the repository is restarted. Then the value read is 0 !
( see attached junit test)

The test pass with versions 1.6.4 and 2.0


regression of JCR-2762.

test case: 

any long value > 0x3FFFFFFFFFFFFFFF (i.e. with any of the 2 most significant bits set)
causes an overflow on deserialization.

this obviously also includes Long.MAX_VALUE and Long.MIN_VALUE...

example:
long test = 0x3FFFFFFFFFFFFFFFL;
 
BundleWriter.writeVarLong(test);
test == BundleReader.readVarLong()  // => ok

test++;
BundleWriter.writeVarLong(test);
=> BundleReader.readVarLong() returns 0

> Long values not properly stored
