Sunitha Kambhampati updated DERBY-1373:
---------------------------------------

    Attachment: 10.1_explicitsvnadd_derby1373.diff.txt

In the earlier patch 10.1_derby1373.diff.txt' the new files didnt get added to the patch because,merge adds the files to the codeline but does not do a svn add.  In this case, svn stat shows A+ which is just the property file changes.  It does not add the file.  

I am attaching a new patch '10.1_explicitsvnadd_derby1373.diff.txt'  that has all the newly added files in it.  

svn stat 
M      java\engine\org\apache\derby\impl\services\jce\JCECipherFactory.java
M      java\testing\org\apache\derbyTesting\functionTests\tests\store\copyfiles.ant
A      java\testing\org\apache\derbyTesting\functionTests\tests\store\encryptionKey_jar.sql
A      java\testing\org\apache\derbyTesting\functionTests\tests\store\encryptionKey_jar_app.properties
A      java\testing\org\apache\derbyTesting\functionTests\master\encryptionKey_jar.out
M      java\testing\org\apache\derbyTesting\functionTests\suites\encryptionAll.runall

Can someone look at this patch. 

Thanks to Deepa for pointing the issue with 'A+' in the svn stat. .

Thanks,
Sunitha.

>
> An encrypted database cannot be booted when using the jar subprotocol.
> The problem lies in the method run from JCECipherFactory. The call to getRandomAccessFile returns null when the verifyKeyFile is an instance of InputStreamFile and the key verification therefore fails.
> The implementation of getRandomAccessFile for InputStreamFile states that its code cannot be reached which is untrue.
> The provided patch does two things, it provides a new class InputStreamRandomAccessFile in package org.apache.derby.impl.io. This class provides simple implementations of readInt and readFully so the key verification process succeeds. A quick scan of the derby source tree showed no problem or possible impact of this simple implementation.
> The second thing the patch does is to modify org/apache/derby/impl/io/InputStreamFile.java so the getRandomAccessFile creates an instance of InputStreamRandomAccessFile instead of returning null.
> This patch has been tested against trunk 410361. It solves the problem at least under the jar subprotocol.
> The patch has not been tested against http/https/classpath.
