public class RemovePeopleDirectoryDuplicatesUpgradeTask
- extends AbstractDeferredRunUpgradeTask
- implements DatabaseUpgradeTask
The index flushing strategy is (intentionally) inaccurate and relies on an in-memory 'flushed entries' cache
to prevent the same object being flushed twice. This risks duplicate entries being created in the index immediately after
the application is restarted if the most recently queued index task entries prior to the restart are AddDocumentIndexTasks.
See CONF-29072 for additional details.
Therefore, this upgrade task changes any recent 'ADD' index task entries in the database to 'UPDATE' tasks
instead, and from this point forward we no longer create 'ADD' entries in isolation.
This upgrade task also re-indexes existing PersonalInformation objects to remove any duplicate entries in the people directory.

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.

doDeferredUpgrade
public void doDeferredUpgrade()
throws java.lang.Exception
- Description copied from interface:
DeferredUpgradeTask
- Run the upgrade that was deferred by an earlier call to doUpgrade.
- Specified by:
doDeferredUpgrade
in interface DeferredUpgradeTask
- Throws:
java.lang.Exception
getBuildNumber
public java.lang.String getBuildNumber()
- Specified by:
getBuildNumber
in interface UpgradeTaskInfo
- Overrides:
getBuildNumber
in class AbstractUpgradeTask
- Returns:
- The build number that this upgrade is applicable to
