Markus Kramer commented on HHH-3440:
------------------------------------
This is the changeset which introduced the bug:
http://fisheye.jboss.org/changelog/Hibernate?cs=14093
And this is the reason:
http://opensource.atlassian.com/projects/hibernate/browse/HHH-2669
It seems to be only a small (maybe unnecessary) optimization. However, it causes severe backward compatibility issues.
Will this be addressed? I hope this change will be reverted soon.
> 3.3.0 GA with MySQL 5.0 throws table validation exception
> ---------------------------------------------------------
>
> Key: HHH-3440
> URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3440
> Project: Hibernate Core
> Issue Type: Bug
> Components: core
> Affects Versions: 3.3.0.GA
> Environment: Hibernate 3.3.0 GA
> MySQL 5.0
> JBoss 4.2.2
> Reporter: Carlo Luib-Finetti
>
> Hibernate immediately throws an exception at application startup, when it does the schema validation.
> org.hibernate.HibernateException: Wrong column type in dpjw.assessment for column NOTES. Found: text, expected: longtext
> Comparing the sources of 3.2.0 with 3.3.0 I can see that someone set two java statements into comment. The 3.2 version of MySQLDialect.java looks like this:
> protected void registerVarcharTypes() {
> registerColumnType( Types.VARCHAR, "longtext" );
> registerColumnType( Types.VARCHAR, 16777215, "mediumtext" );
> registerColumnType( Types.VARCHAR, 65535, "text" );
> registerColumnType( Types.VARCHAR, 255, "varchar($l)" );
> }
> while the new 3.3.0 version is this:
> protected void registerVarcharTypes() {
> registerColumnType( Types.VARCHAR, "longtext" );
> // registerColumnType( Types.VARCHAR, 16777215, "mediumtext" );
> // registerColumnType( Types.VARCHAR, 65535, "text" );
> registerColumnType( Types.VARCHAR, 255, "varchar($l)" );
> }
> If I uncomment these (and others in the same Java file!), the validation process is ok.
> Is there any reason why these statements (and others!) were commented out???
