public class ContentParentTypeFixingUpgradeTask
extends AbstractUpgradeTask
implements DatabaseUpgradeTask

When writing StorageToAoMigrationUpgradeTask in the Inline Tasks plugin, we discovered that CAC had some trashed pages whose parent was a blog post. Some investigation into code followed to determine how this may have happened, and while we could not determine the exact way this could have happened, we found some code paths that could lead to the content type of an object changing (and fixed them). See CONF-17972 and HHH-416. This upgrade task was written to clean up instances with data like that just so other code doesn't blow up. We can't use Hibernate here because it would blow up as the ORM mapping is not as described in the HBM file.

Constructor Detail


public ContentParentTypeFixingUpgradeTask(net.sf.hibernate.SessionFactory sessionFactory)
Method Detail


public String getBuildNumber()
Specified by:
getBuildNumber in interface UpgradeTaskInfo
getBuildNumber in class AbstractUpgradeTask
The build number that this upgrade is applicable to


public void doUpgrade()
               throws Exception
Description copied from interface: UpgradeTask
Perform the upgrade.

Specified by:
doUpgrade in interface UpgradeTask


public boolean runOnSpaceImport()
Description copied from interface: BackupSupport
Returns true if an older Space can't be imported in a new instance without running this task. For example:

Note that tasks don't run on space import yet, so we just reject the import in this case.

Specified by:
runOnSpaceImport in interface BackupSupport


public boolean breaksBackwardCompatibility()
Description copied from interface: BackupSupport
Returns true if a new export can't be imported in an older instance. Breaking compatibility means a snapshot of the new version will not work at all with the previous version. For example: The best way to test is whether a newer export can be imported (with fully working features) in an older instance.

Specified by:
breaksBackwardCompatibility in interface BackupSupport
