public class ReferencedUsersUserMappingUpgradeTask
extends AbstractUserMappingUpgradeTask
implements DatabaseUpgradeTask

Upgrade task to ensure that for all the user names in Confluence a ConfluenceUser object exist. Various username related columns across all content table are considered. This is consistent with Confluence's behaviour of allowing content to be owned/created/modified/whatever by non-existent users. Note that various "post schema" upgrade tasks assume this task has already run and make the assumption that all content referenced users are populated in the user_mapping table (ConfluenceUser). e.g. UserIndexingUpgradeTask.

Method Detail

getUsernamesMissingMapping

protected Set<String> getUsernamesMissingMapping()
Specified by:
getUsernamesMissingMapping in class AbstractUserMappingUpgradeTask

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:

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: 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

getBuildNumber

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

getShortDescription

public String getShortDescription()
Description copied from interface: UpgradeTaskInfo
A short (<50 chars) description of the upgrade action

Specified by:
getShortDescription in interface UpgradeTaskInfo
Overrides:
getShortDescription in class AbstractUpgradeTask
