Method Detail

setSessionFactory5

public void setSessionFactory5(org.hibernate.SessionFactory sessionFactory)

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

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

doUpgrade

public void doUpgrade()
               throws Exception

Description copied from interface: UpgradeTask

Perform the upgrade.

Specified by:

doUpgrade in interface UpgradeTask

Throws:

Exception

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.

Specified by:

breaksBackwardCompatibility in interface BackupSupport
