Class AddMissingUnmanagedUniqueConstraintsUpgradeTask

java.lang.Object
com.atlassian.confluence.upgrade.AbstractUpgradeTask
com.atlassian.confluence.upgrade.upgradetask.AddMissingUnmanagedUniqueConstraintsUpgradeTask
All Implemented Interfaces:
BackupSupport, DatabaseUpgradeTask, UpgradeTask, UpgradeTaskInfo, org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanNameAware
public class AddMissingUnmanagedUniqueConstraintsUpgradeTask extends AbstractUpgradeTask implements DatabaseUpgradeTask
Because of CONFSERVER-38706, some unique constraints which are not managed by Hibernate have been missing for instances freshly installed with Confluence 5.6 - 5.8. Affected constraints can be found in findAllConstraints()} This Upgrade task aims to add all of them gracefully and seamlessly. Duplicates are removed if any before constraints are added.
Since:
7.1.0

  • Method Details

    • runOnSpaceImport

      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:
      • A task updating macro names in the BodyContent table would be blocking.
      • Tasks which updates data related to the space would be blocking.
      • A task upgrading the user table wouldn't be blocking.
      • Adding a mandatory column on space-related content breaks space import

      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

    • breaksBackwardCompatibility

      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:

      • A destructive operation (Some data is replaced by another) breaks backwards compatibility
      • Adding a optional column does NOT break backwards compatibility
      • Data is copied to another column doesn't breaks backwards compatibility
      • A build number incrementation doesn't breaks backwards compatibility
      The best way to test is whether a newer export can be imported (with fully working features) in an older instance.
