Compared with the previous release (10.8.2.2), Derby release 10.8.3.0 introduces the following new features and incompatibilities. These merit your special attention.
The SQL state of the error returned from a lock timeout when the property "derby.locks.deadlockTrace=true" is set will return 40XL1 rather than 40XL2.
In the previous release, applications which set "derby.locks.deadlockTrace=true" would get error 40XL2 when a lock timeout was received. This was confusing as simply setting the system to return extra diagnostic information would change the SQL state of the error returned by the system for a lock timeout.
Applications which explicitly tested for SQL state error 40XL2 as a lock timeout will no longer get that error. 40XL1 will now always be returned for a lock timeout error whether lock diagnostics are enabled or not.
The previous behavior was not intended. Lock timeout should generate same SQL state whether diagnostics are enabled or not. Only the text of the error will change based on the requested diagnostic level.
If the application has been explicitly coded to take action when getting error 40XL2 and does not do the same action for 40XL1, then the application should be changed. This action is usually retry logic based on a lock timeout or deadlock.
Derby can pick incorrect join column value for a RIGHT OUTER JOIN with NATURAL/USING clause.
In case of RIGHT OUTER JOIN with NATURAL/USING clause, Derby always picked the join column's value from the right table. This could lead to incorrect join column value depending on the data in the tables. The correct value should be determined by doing equivalent of COALESCE(leftTableValue, rightTableValue). This correct behavior has been implemented as a fix for DERBY-4631.
The data returned for join column value for a RIGHT OUTER JOIN with NATURAL/USING clause can now be different(and correct).
Derby release 10.8.3.0 was built using the following environment:
It is essential that you verify the integrity of the downloaded files using the PGP and MD5 signatures. MD5 verification ensures the file was not corrupted during the download process. PGP verification ensures that the file came from a certain person.
The PGP signatures can be verified using
PGP or
GPG.
First download the Apache Derby
KEYS
as well as the asc signature file for the particular
distribution. It is important that you get these files from the ultimate
trusted source - the main ASF distribution site, rather than from a mirror.
Then verify the signatures using ...
% pgpk -a KEYS % pgpv db-derby-X.Y.tar.gz.asc or % pgp -ka KEYS % pgp db-derby-X.Y.tar.gz.asc or % gpg --import KEYS % gpg --verify db-derby-X.Y.tar.gz.asc
To verify the MD5 signature on the files, you need to use a program
called md5 or md5sum, which is
included in many unix distributions. It is also available as part of
GNU
Textutils. Windows users can get binary md5 programs from here, here, or
here.
We strongly recommend that you verify your downloads with both PGP and MD5.
