Constructor Detail

DefaultUpgradeManager

public DefaultUpgradeManager()

Method Detail

afterPropertiesSet

public void afterPropertiesSet()

Specified by:

afterPropertiesSet in interface org.springframework.beans.factory.InitializingBean

Overrides:

afterPropertiesSet in class AbstractUpgradeManager

getRealBuildNumber

protected String getRealBuildNumber()

Specified by:

getRealBuildNumber in class AbstractUpgradeManager

Returns:

The build number of the new version of Confluence being upgraded to. This number can be found in the default.properties of the new expanded WAR

getDatabaseBuildNumber

protected String getDatabaseBuildNumber()

Specified by:

getDatabaseBuildNumber in class AbstractUpgradeManager

Returns:

The build number of the data in the database. If the version of the database data can not be determined, this method should return the same value as AbstractUpgradeManager.getConfiguredBuildNumber().

runUpgradePrerequisites

protected List<UpgradeError> runUpgradePrerequisites()

Description copied from class: AbstractUpgradeManager

Runs all upgrade prerequisites.

Specified by:

runUpgradePrerequisites in class AbstractUpgradeManager

Returns:

an empty list if all upgrade prerequisites pass, otherwise, returns a list consisting of one or more failure messages.

needUpgrade

public boolean needUpgrade()

This method has a side effect of putting an entry into the published cache indicating whether an upgrade is required or not.

Specified by:

needUpgrade in interface UpgradeManager

Overrides:

needUpgrade in class AbstractUpgradeManager

setDatabaseBuildNumber

public void setDatabaseBuildNumber()

Description copied from interface: UpgradeManager

Once installation is complete, we'll need to set the database build number in the database, so that a subsequent startup of Confluence is able to check that the home directory build number matches the database build number (see https://jira.atlassian.com/browse/CONF-13798).

setDatabaseBuildNumber

protected void setDatabaseBuildNumber(String databaseBuildNumber)
                               throws Exception

Description copied from class: AbstractUpgradeManager

Once the upgrade is complete, we'll need to set the new database build number in the database.

Specified by:

setDatabaseBuildNumber in class AbstractUpgradeManager

Parameters:

databaseBuildNumber - The new database build number

Throws:

Exception - when there is any problem setting the database build number

beforeUpgrade

protected void beforeUpgrade()

Overrides:

beforeUpgrade in class AbstractUpgradeManager

postUpgrade

protected void postUpgrade()

Overrides:

postUpgrade in class AbstractUpgradeManager

initialUpgradeFinished

protected void initialUpgradeFinished()
                               throws Exception

Update the pluginFrameworkDependent upgrade status based on whether there are any plugin framework dependent upgrade tasks to run.

Overrides:

initialUpgradeFinished in class AbstractUpgradeManager

Throws:

Exception - when setting the database or configuration build number fails

entireUpgradeFinished

public void entireUpgradeFinished()

Description copied from interface: UpgradeManager

Called when all immediate and deferred upgrade actions have been performed *if* an upgrade was needed.

Specified by:

entireUpgradeFinished in interface UpgradeManager

Overrides:

entireUpgradeFinished in class AbstractUpgradeManager

permitDatabaseUpgrades

protected boolean permitDatabaseUpgrades()

If we are in a clustered setup, only one node should be allowed to perform upgrades that affect the database. To enforce this, nodes will need to:

• successfully acquire the cluster upgrade lock AND
• successfully tag the build in the CONFVERSION table (this is a backup check, to help us detect rare cases where some cluster nodes are not communicating - producing multiple clusters)

If the upgrade process fails before all database upgrade tasks are complete, and the user ignores those errors and restarts the server, the existing tag on the CONFVERSION table will prevent the upgrade

Overrides:

permitDatabaseUpgrades in class AbstractUpgradeManager

Returns:

True by default. Is overridden for cluster upgrades.

runUpgradeTasks

protected void runUpgradeTasks(List<UpgradeTask> upgradeTasks)
                        throws UpgradeException

Overrides:

runUpgradeTasks in class AbstractUpgradeManager

Throws:

UpgradeException
