setUpgradeTasks

public void setUpgradeTasks(List<UpgradeTask> upgradeTasks)

getUpgradeTasks

public List<UpgradeTask> getUpgradeTasks()

setSchemaUpgradeTasks

public void setSchemaUpgradeTasks(List<UpgradeTask> upgradeTasks)

getSchemaUpgradeTasks

public List<UpgradeTask> getSchemaUpgradeTasks()

getErrors

public List<UpgradeError> getErrors()

Specified by:

getErrors in interface UpgradeManager

runUpgradePrerequisites

protected abstract List<UpgradeError> runUpgradePrerequisites()

Runs all upgrade prerequisites.

Returns:

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

getConfiguredBuildNumber

protected String getConfiguredBuildNumber()

Returns:

The build number of the current version that the user is running under. This version is stored in their confluence home confluence.cfg.xml file

setConfiguredBuildNumber

protected void setConfiguredBuildNumber(String buildNumber)
                                 throws com.atlassian.config.ConfigurationException

Throws:

com.atlassian.config.ConfigurationException

needUpgrade

public boolean needUpgrade()

Specified by:

needUpgrade in interface UpgradeManager

upgradeFinished

protected void upgradeFinished()
                        throws Exception

Once all upgrade tasks have been completed without error, make sure the build number stored in the applications main configuration file and database now matches the build number of this version of the release.

Throws:

Exception - when setting the database or configuration build number fails

getRealBuildNumber

protected abstract String getRealBuildNumber()

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 abstract String getDatabaseBuildNumber()

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 getConfiguredBuildNumber().

setDatabaseBuildNumber

protected abstract void setDatabaseBuildNumber(String databaseBuildNumber)
                                        throws Exception

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

Parameters:

databaseBuildNumber - The new database build number

Throws:

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

permitDatabaseUpgrades

protected boolean permitDatabaseUpgrades()
                                  throws UpgradeException

This is used to guard against database upgrades being performed multiple times on the same database. By default, assume a non-clustered setup and allow database upgrades.

Returns:

True by default. Is overridden for cluster upgrades.

Throws:

UpgradeException - If the implementation of this method encounters any errors.

postUpgrade

protected void postUpgrade()

isUpgraded

public boolean isUpgraded()

Specified by:

isUpgraded in interface UpgradeManager

Returns:

true if the UpgradeManager was able to successfully upgrade this instance, or if no upgrade was necessary; otherwise false.
