Method Summary

Modifier and Type	Method and Description
void	createStateRecordsIfTheyDoNotExist() When the service is starting up for the first time, we need to create "state records".
void	destroy()
void	disableService(boolean cleanDenormalisedData) Disables the service and deletes all triggers/functions, so denormalised data will not be updated.
void	enableContentService()
void	enableService() Enables the service.
void	enableSpaceService()
Long	getContentPermissionUpdateLag() Returns the time difference between updating regular content permissions and denormalised content permissions
DenormalisedPermissionServiceState	getContentServiceState(boolean realTimeData) Get the state of denormalised content service.
Long	getSpacePermissionUpdateLag() Returns the time difference between updating regular space permissions and denormalised space permissions
DenormalisedPermissionServiceState	getSpaceServiceState(boolean realTimeData) Get the state of denormalised space service.
List<StateChangeInformation>	getStateChangeLog(int limit) Returns a list of service state change events
void	init()
boolean	isApiReady() Returns true if the state of the service is "READY", if both CONTENT and SPACE services are in ready state Possible reasons for returning false: 1.
boolean	isContentApiReady() Returns true if the state of denormalised CONTENT service is "READY", which means that denormalised content permissions reflect real permissions.
boolean	isSpaceApiReady() Returns true if the state of denormalised SPACE service is "READY", which means that denormalised space permissions reflect real permissions.

void	onApplicationStoppingEvent(com.atlassian.config.lifecycle.events.ApplicationStoppingEvent event)
void	reloadServiceState() We need to support it's state in memory because we'd like to avoid reading this value from DB for every request denormalised permissions receive.

DenormalisedPermissionStateManagerImpl

                                              DenormalisedServiceStateDao denormalisedServiceStateDao,

Method Detail

init

@PostConstruct
public void init()

scheduled

@Scheduled(fixedDelay=3000L)
public void scheduled()

Specified by:

scheduled in interface DenormalisedPermissionStateManager

reloadServiceState

@Internal
public void reloadServiceState()

We need to support it's state in memory because we'd like to avoid reading this value from DB for every request denormalised permissions receive. This state is used in router to switch between real denormalised permissions and the fallback service.

isApiReady

public boolean isApiReady()

Returns true if the state of the service is "READY", if both CONTENT and SPACE services are in ready state Possible reasons for returning false: 1. Service is disabled 2. Denormalized tables are not ready

Specified by:

isApiReady in interface DenormalisedPermissionStateManager

Returns:

the state of the service

isSpaceApiReady

public boolean isSpaceApiReady()

Returns true if the state of denormalised SPACE service is "READY", which means that denormalised space permissions reflect real permissions. Possible reasons for returning false: 1. Service is disabled 2. Denormalized tables are not ready

Specified by:

isSpaceApiReady in interface DenormalisedPermissionStateManager

Returns:

the state of the SPACe service

isContentApiReady

public boolean isContentApiReady()

Returns true if the state of denormalised CONTENT service is "READY", which means that denormalised content permissions reflect real permissions. Possible reasons for returning false: 1. Service is disabled 2. Denormalized tables are not ready

Specified by:

isContentApiReady in interface DenormalisedPermissionStateManager

Returns:

the state of the SPACe service

getSpaceServiceState

public DenormalisedPermissionServiceState getSpaceServiceState(boolean realTimeData)

Description copied from interface: DenormalisedPermissionStateManager

Get the state of denormalised space service.

Specified by:

getSpaceServiceState in interface DenormalisedPermissionStateManager

Parameters:

realTimeData - if true, data will be read from the DB. If false, cached data will be returned.

Returns:

the state of denormalised SPACE service

getContentServiceState

public DenormalisedPermissionServiceState getContentServiceState(boolean realTimeData)

Description copied from interface: DenormalisedPermissionStateManager

Get the state of denormalised content service.

Specified by:

getContentServiceState in interface DenormalisedPermissionStateManager

Parameters:

realTimeData - if true, data will be read from the DB. If false, cached data will be returned.

Returns:

the state of denormalised CONTENT service

enableService

public void enableService()

Enables the service. It would take some time to update denormalised data

Specified by:

enableService in interface DenormalisedPermissionStateManager

enableSpaceService

public void enableSpaceService()

enableContentService

public void enableContentService()

createStateRecordsIfTheyDoNotExist

@Internal
public void createStateRecordsIfTheyDoNotExist()
                                                  throws ExecutionException,
                                                         InterruptedException

When the service is starting up for the first time, we need to create "state records". It's important to do this in separate transaction because these records will be used for cluster-wide locking.

Throws:

ExecutionException

InterruptedException

getSpacePermissionUpdateLag

public Long getSpacePermissionUpdateLag()

Returns the time difference between updating regular space permissions and denormalised space permissions

Specified by:

getSpacePermissionUpdateLag in interface DenormalisedPermissionStateManager

Returns:

lag in ms, or null if the data record is not found (for example, the service has never been enabled)

getContentPermissionUpdateLag

public Long getContentPermissionUpdateLag()

Returns the time difference between updating regular content permissions and denormalised content permissions

Specified by:

getContentPermissionUpdateLag in interface DenormalisedPermissionStateManager

Returns:

lag in ms, or null if the data record is not found (for example, the service has never been enabled)

disableService

public void disableService(boolean cleanDenormalisedData)

Disables the service and deletes all triggers/functions, so denormalised data will not be updated.

Specified by:

disableService in interface DenormalisedPermissionStateManager

Parameters:

cleanDenormalisedData - - if true, all denormalised data will be truncated

getStateChangeLog

public List<StateChangeInformation> getStateChangeLog(int limit)

Returns a list of service state change events

Specified by:

getStateChangeLog in interface DenormalisedPermissionStateManager

Parameters:

limit - limit

Returns:

list or events, sorted by event date (desc)

onApplicationStartedEvent

@EventListener
public void onApplicationStartedEvent(com.atlassian.config.lifecycle.events.ApplicationStartedEvent event)

onApplicationStoppingEvent

@EventListener
public void onApplicationStoppingEvent(com.atlassian.config.lifecycle.events.ApplicationStoppingEvent event)

destroy

public void destroy()
             throws Exception

Specified by:

destroy in interface org.springframework.beans.factory.DisposableBean

Throws:

Exception
