Method Detail

doDeferredUpgrade

public final void doDeferredUpgrade()
                             throws Exception

Description copied from interface: DeferredUpgradeTask

Run the upgrade that was deferred by an earlier call to doUpgrade.

Throws:

Exception

shouldRun

protected boolean shouldRun()

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.

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.
