Events - processing of events

An event mechanism has been designed to make extending and overlapping of the CzechIdM core functionality within any module possible.

The event (EntityEvent) with type (EventType) is published via EntityEventManager from different places in the application (⇒ hook). A number of processors can react to the event (AbstractEntityEventProcessor) in a defined order (number ⇒ the smaller it is, the sooner the processor is run). Processors run synchronously at default and in one transaction (see next section). Processors with the same order will be run in a random order (OrderComparator) - it's good practice to design and set different processor's order (think about it in design). Instead of the annotation @Order, the method getOrder needs to be overloaded (see the example). Event content could be any Serializable object, but AbstractDto descendant is preffered - see original source lifecycle feature. Event content is required, event without content couldn't exist.

  • Event is created with given content
EntityEvent<IdmIdentityDto> event = new IdentityEvent(IdentityEventType.UPDATE, updateIdentity);
  • then is given to the processing via EntityEventManager
EventContext<IdmIdentityDto> context = entityEventManager.process(event);
  • when event is published and their content is descendant of AbstractDto, then original source is filled to the event - original source contains previously persisted (original) dto and could be used in "check modification" processors. If event creating new dto, then original source is null. Original source could be set externally - then no automatic filling occurs.
  • returning context contains results from all reacting processors in defined processors order.
  • the processor can label the event as (closed) or (suspended) and therefore skip all the other processors. If the suspended event is published again via EntityEventManager, the processing will continue where it was suspended, if context (with processed results) is preserved. If the processing of the event is (suspended), the called method should return the adequate accepted state.
  • when event walk through processors, then event's processed order is incremented - this order is used after event suspending and run again - event processing will continue with processor with the next order. Look out: when event is persisted, she will lost their context ⇒ when event is recreated from persistent state, she will continue with the next order.

Event is published with content and specific event type (e.g. CREATE, PASSWORD). Processors can be register by content type and event type - e.g. process event with IdmIdentityDto content and event type CREATE ⇒ other event contents and other event types will not be processed by this processor.

Event types has to be compared by their string representation, NOT by instance. Concrete event types e.q. IdentityEventType are used for documentation reason only - which domain type supports which event. Event types can be added in different modules with different type, but processor can react across all module (⇒ is registered to string event type representation eventType.name()).

...
EntityEvent<IdmIdentityDto> event = new CoreEvent<IdmIdentityDto>(CoreEventType.CREATE, identity);
if (event.hasType(IdentityEventType.CREATE)) {
 // do something
}
...

Module can publish their own event types. Basic (core) event types

  • CREATE - synchronous, new entity is created
  • UPDATE - synchronous, entity is updated
  • DELETE - synchronous, entity is removed
  • NOTIFY - asynchronous, notify about entity is changed (CU).
  • EAV_SAVE - synchronous, some entity extended attribute is modified (CUD) - it is synonym for NOTIFY type ⇒ notify about entity extended attribute is changed (only extended attribute is changed). When entity is saved together with extended attributes, then only source event (e.g. CREATE) on owner entity is published (⇒ eav attributes are saved after owner entity is saved in once process line - e.g. CREATE).

Different (and custom) event types can be used for different entities.

A page has been created directly in the application on the module page for an overview of all entity types and event types migrating through event processing. All the registered processors including the configuration are listed there:

The default order for listeners (- ⇒ before, + ⇒ after):

  • core: 0
  • provisioning: 1000
  • delete / archivate processed: 5000
  • EntityEvent - an event migrating through the processors. The content of the event can be BaseEntity, BaseDto or any serializable content.
  • EventContext - holds the context of the processed event - which processors it has been processed by, with what results, if the processing is suspended, closed, etc.
  • EventResult - the result of processing of the event by one processor.
  • EntityEventProcessor - event processor. Processor has to have unique identifier by module.
  • AsyncEntityEventProcessor - asynchronous entity event processor. Processor can control asynchronous processing priority.
  • EntityEventManager - ensures publishing of the event to processors.
  • EventableDtoService - adds event processing support to service - event processors have to be provided (e.g. for save, delete).
  • AbstractEntityEvent - an abstract event migrating through the processors - when adding a proper one can be simply inherited from.
  • DefaultEventContext - the default context of the processed event - all abstract and default events and processors use it.
  • DefaultEventResult - The default event result processed by one processor - all abstract and default events and processors use it.
  • AbstractEntityEventProcessor - abstract event processor - when adding a proper one can be simply inherited from.
  • AbstractApprovableEventProcessor - the event processor will send the whole event with dto (or serializable) content to WF for approval. It is necessary to configure the definition of the WF where the event will be sent to.
  • AbstractPublishEntityChangeProcessor - publish asynchronous NOTIFY event.
  • DefaultEntityEventManager - ensures publishing of the events to processors.
  • AbstractEventableDtoService - adds default event processing support to service - event processors have to be provided (e.g. for save, delete).

AbstractEntityEventProcessor

Use this super class, when creating new processor implementation (this class contains some boring parts).

Methods, which have to be implemented:

  • getName() - Unique (module scope) configurable object identifier. Its used in configuration key etc.
  • process(event) - the main processors method with business logic.
  • getOrder() - when will be processor processed. Processors are executed in defined order.

Methods, which could be implemented [optional]:

  • supports(event) - Returns true, when processor supports given event. Default implementation takes processor's template entity class and event type given in constructor (or configured by eventTypes property).
  • conditional(event) - Returns true, when processor supports given event. Returns true by default. Override this method for adding some condition.
  • isClosable() - Returns true, when processor could close event (only documentation purpose now). Returns false by default.

AsyncEntityEventProcessor

Use this super class, when creating new asynchronous processor implementation.

Methods, which could be implemented [optional]:

  • getPriority(event) - Registered async processor can vote about priority of processing for given event. Returns null by default ⇒ processor doesn't vote about priority - preserve original event priority. Use IMMEDIATE to execute whole event synchronously. All registered processors votes about event priority - whole event will be processed with the highest priority.

Transactional processing is controlled before the event publishing itself - the whole processing now takes place in a one transaction and all processors run synchronously by default. In case of an error in any processor, the whole transaction is rolled back, which has some advantages:

  • simple adding of validation or referential integrity
  • repeating the whole chain

and disadvantages as well:

  • having to catch all the exceptions properly to avoid "breaking the chain"
  • saving logs and archives in the new transaction (Propagation.REQUIRES_NEW)

Event properties (Map) can be specified for the event. Properties could be used in event processing.

Event properties are propagated automatically from parent into child event:

  • if parent event is given, when child event is published
  • if child event doesn't contain property with the same key - property can be preset manually and has a higher priority.
  • properties needed for internal event mechanism are not propagated. Property keys can be found in EntityEvent.
When NOTIFY event is published and event will be processed synchronously (asynchronous event processing is disabled or event has IMMEDIATE priority), the properties set by processing NOTIFY event is also available in the original event.

CzechIdM 8.0.0 brings new feature - asynchronous event processing. New event type NOTIFY was added, all previous events (CREATE, UPDATE, DELETE, EAV_SAVE etc.) are still synchronous.

Asynchronous NOTIFY event is published for dtos:

  • IdmIdentityDto - published, when identity is created or updated (or eav is saved, updated, deleted)
  • IdmIdentityContractDto- published, when contract is created or updated (or eav is saved, updated, deleted)
  • IdmContractGuaranteeDto- published, when contract guarantee is created or updated (or eav is saved, updated, deleted)
  • IdmIdentityRoleDto- published, when identity role is created or updated (or eav is saved, updated, deleted)
  • IdmRoleDto- published, when role is created or updated (or eav is saved, updated, deleted)
  • IdmRoleRequestDto- published, when request is completely approved or executed - provisioning listen this event mainly.
  • IdmTreeNodeDto- published, when tree node is created or updated (or eav is saved, updated, deleted)
  • IdmRoleCatalogueDto- published, when identity role catalogue is created or updated (doesn't have eav attributes)
As you can see, entity DELETE event is still synchronous.

Other entities will be added soon, when new asynchronous entity event processors will be implemented.

NOTIFY event type is processed asynchronously:

  • order 500 - by automatic roles in core module,
  • order 1000 - by account management in acc module, then provisioning is executed.

When asynchronous event is published, it's persisted into event queue (IdmEntityEvent). Internal scheduled task executes events from queue - all registered processors for event type NOTIFY is processed - the same behavior as standard event processing, processors are called in defined order synchronously by defult. Event (~entity) states (IdmEntityState) are persisted during event is processed (created / running / failed). Successfully processed events are deleted from queue by processor EntityEventDeleteExecutedProcessor. When exception occurs, event stays in queue with appropriate result code. Event agenda is available under APP_ADMIN permission on frontend from audit menu (shortcut tab can be added on all entity details e.g. see identity detail).

Features

Process event from queue

Events from queue are processed by event owner id - one event for one owner can be executed in the same time ⇒ we need to preserven event order by created date for one owner. Super owner id (EntityEventManager.EVENTPROPERTYSUPEROWNERID) can be used for setting custom event owner - this property will be resolved for evaluating running events for the same owner concurrency.

Events from queue can be deleted only (events without children can be deleted now from FE). Operation for retry failed events on truncate all events in queue will be developed in future.

Event priority

Before event is persisted into queue, then event priority is evaluated, priority types:

  • IMMEDIATE - immediate ~ synchronously. Event will be executed synchronously.
  • HIGH - asynchronously (7 / 10 in one cycle, batch size can be configured)
  • NORMAL - asynchronously (3 / 10 in one cycle, batch size can be configured)

Events are processed from queue by internal scheduled tasks by priority. Events with HIGH priority will use 7 slots, events with NORMAL priority will use 3 slots ⇒ events will be processed 7 / 3, when internal scheduled task for processing events will be executed.

Priority can be set to event manually or registered processors can vote about event's priority - see AsyncEntityEventProcessor - the highest priority is used.

Execute date

Execute date can be set to event manually. Event with priority HIGH or NORMAL will be processed after given date. Can be used for events, which could be executed sometimes "in night".

Parent event

Event can be published by another event ~ event chain (tree) is persisted. For example, when contract is saved, then contract NOTIFY event is published. This event is processed by provisioning processors - but only NOTIFY event with contract's identity is published here only. Provisioning is physically executed in other processor, which processes identity NOTIFY event.

Event parameters

When asynchronous event is published, then event content (and previous ~ original content) and event parameters is persisted into queue. This persisted attributes are used, when event is resurrected from queue and executed. Attributes are available in registered asynchronous processors - evaluate modifications, skipping by event parameter value etc. can be implemented in processors business logic.

Remove duplicate events

When internal scheduled task for executing event from queue is processed, then duplicate events are removed.

Duplicate event is event with the same:

  • owner
  • event type
  • event properties
  • original source (embedded dtos and audit fields are ignored).

Older duplicate events are removed - the newest event is used. Events are processed by priority in batch, default batch size can be configured ⇒ duplicates are removed only in this batch (not configurable for now, see future development). Batch size is designed this way, because events are processed by priority - event with HIGH priority should not wait too long for another bulk is begin to process. Remove duplicates should be redesigned from scratch - remove duplicates through whole queue.

Entity state

Persist event (~entity) state, when event is processed. State can be persisted manually, even without event processing. This state will be shown on entity detail soon (new frontend component).

Notification

Notification about registered asynchronous processors is prepared, when asynchronous event is published. Notification is send into topic core:event - uses console log by default and is send to currently logged identity - e.g. identity is saved, but provisioning will be executed asynchronously. Localization for asynchronous processors was added on frontend (see key acc:processor.identity-save-processor).

Configuration

  • Scheduler - configure internal scheduled tasks for processing events from queue.
  • Event processing - configure asynchronous event processing
  • Processors - configure entity event processors.
  • 0 - basic / core functionality - operation save, delete etc.
  • 50 - save eav, which are send together with owner's dto
  • 100 - automatic roles computation.
  • 1000 - after save - e.g. sends notifications.
  • 10000 - publish NOTIFY event about entity is changed.
  • -1000 - before delete provisioning (before identity role is deleted).
  • Identity:
    • -2000 - validate password in acc module - checks all system password policies and idm default policy ⇒ all policies are evaluated in one request. If acc module is enabled, then core password validation processor can be disabled.
    • -1000 - validate password in core module - checks idm default policy.
    • 100 - persist password
  • Contract:
    • 100 - Automatic roles recount while identity contract is saved, updated or deleted / disabled.
  • LongRunningTask:
    • 100 - execute scheduled long running tasks, which depends on currently ended scheduled task.
  • Provisioning:
    • -5000 - check disabled system
    • -1000 - compute attributes for provisioning (read attribute values from target system)
    • -500 - check readonly system
    • 0 - execute provisioning (create / update / delete)
    • 1000 - execute after provisioning actions (e.g. sends notifications)
    • 5000 - archive processed provisioning operation.

Other orders can be found directly in application, see supported event types.

Processors can be configured through Configurable interface by standard application configuration.

Duplicate role processors

Processors

Implemented processors in the product sorted by order of the processing:

DuplicateRolePrepareProcessor

@since 9.5.0

  • Event content: IdmRoleDto
  • Event type: DUPLICATE
  • Default order: -1000

Prepares role's basic properties.

Register custom processor after this processor's order, if some role basic property has to be overriden (or filled by different business logic).
## Enable / disable
idm.sec.core.processor.core-duplicate-role-prepare-processor.enabled=true
DuplicateRoleSaveProcessor

@since 9.5.0

  • Event content: IdmRoleDto
  • Event type: DUPLICATE
  • Default order: 0

Here is the role persisted into database.

Register custom processor after this processor's order, if some related entities has to be duplicated (e.g. guarantees).

idm.sec.core.processor.core-duplicate-role-save-processor.enabled=true
DuplicateRoleFormAttributeProcessor

@since 9.5.0

  • Event content: IdmRoleDto
  • Event type: DUPLICATE
  • Default order: 50

Duplicate role form attributes - parameters for the identity (~assigned) roles. Parameters are created for the target role or updated - extended attribute code is used for pairing.

Parameters provided to the bulk action form:

  • Duplicate role form attributes - if role form attributes will be duplicated.

Configuration properties:

DuplicateRoleCompositionProcessor

@since 9.5.0

  • Event content: IdmRoleDto
  • Event type: DUPLICATE
  • Default order: 100

Duplicate configured role composition (sub roles by business role definition) and duplicate sub roles recursively. If the same environment is selected, the only role composition is created - existing sub roles are used. If the different environment (~target environment) is used, then sub roles with the same environment as original are duplicated recursively into target environment.

Parameters provided to the bulk action form:

  • Duplicate sub roles (by business role definition) - if business role configuration will be duplicated (recursively).

Overidable methods (can be used for on the projects, e.g. example below):

  • duplicateRecursively - Returns true, when role should be cloned recursively - can be overriden, if some role hasn't be cloned recursively, if doesn't exist on the target environment before.
  • includeComposition - Returns true, when role composition should be included in the target role - can be overriden, if some role hasn't be cloned recursively, if doesn't have the same environment etc.

Custom processor example

Core processor can be disabled and overriden by processor implemented in custom module, if behavior of the core processor has to be changed.

Synchronous processor

If we want to get hooked after updating the identity, we should implement a processor to the event type IdentityEventType.UPDATE with an order number higher than 0:

@Enabled(ExampleModuleDescriptor.MODULE_ID)
@Component("exampleLogIdentityUpdateSyncProcessor")
@Description("Logs after identity is updated")
public class LogIdentityUpdateSyncProcessor
		extends CoreEventProcessor<IdmIdentityDto> 
		implements IdentityProcessor {
 
	/**
	 * Processor's identifier - has to be unique by module
	 */
	public static final String PROCESSOR_NAME = "log-identity-update-sync-processor";
	private static final org.slf4j.Logger LOG = org.slf4j.LoggerFactory
			.getLogger(LogIdentityUpdateSyncProcessor.class);
 
	public LogIdentityUpdateSyncProcessor() {
		// processing identity UPDATE event only
		super(IdentityEventType.UPDATE);
	}
 
	@Override
	public String getName() {
		// processor's identifier - has to be unique by module
		return PROCESSOR_NAME;
	}
 
	@Override
	public EventResult<IdmIdentityDto> process(EntityEvent<IdmIdentityDto> event) {
		// event content - identity
		IdmIdentityDto updateddIdentity = event.getContent();
		// log
		LOG.info("Identity [{},{}] was updated.", updateddIdentity.getUsername(), updateddIdentity.getId());
		// result
		return new DefaultEventResult<>(event, this);
	}
 
	@Override
	public int getOrder() {
		// right after identity update
		return CoreEvent.DEFAULT_ORDER + 1;
	}
}

Asynchronous processor

If we want to implement the same feature as above but asynchronously, we can process asynchronous IdentityEventType.NOTIFY instead IdentityEventType.UPDATE. When we need to change synchronous processors to asynchronous, we can simply change processed event type and add some condition, when only some original event types has to be processed ⇒ asynchronous NOTIFY event type is published for CREATE, UPDATE and EAV_SAVE event types.

@Enabled(ExampleModuleDescriptor.MODULE_ID)
@Component("exampleLogIdentityUpdateAsyncProcessor")
@Description("Logs after identity is updated")
public class LogIdentityUpdateAsyncProcessor
		extends CoreEventProcessor<IdmIdentityDto> 
		implements IdentityProcessor {
 
	/**
	 * Processor's identifier - has to be unique by module
	 */
	public static final String PROCESSOR_NAME = "log-identity-update-async-processor";
	private static final org.slf4j.Logger LOG = org.slf4j.LoggerFactory
			.getLogger(LogIdentityUpdateAsyncProcessor.class);
 
	public LogIdentityUpdateAsyncProcessor() {
		// processing identity NOTIFY event only
		super(IdentityEventType.NOTIFY);
	}
 
	@Override
	public boolean conditional(EntityEvent<IdmIdentityDto> event) {
		// we want to process original UPDATE event only
		// async NOTIFY event is published for CREATE, UPDATE, EAV_SAVE event types
		return super.conditional(event)
				&& IdentityEventType.UPDATE.name().equals(event.getProperties().get(EntityEventManager.EVENT_PROPERTY_PARENT_EVENT_TYPE));
	}
 
	@Override
	public String getName() {
		// processor's identifier - has to be unique by module
		return PROCESSOR_NAME;
	}
 
	@Override
	public EventResult<IdmIdentityDto> process(EntityEvent<IdmIdentityDto> event) {
		// event content - identity
		IdmIdentityDto updateddIdentity = event.getContent();
		// log
		LOG.info("Identity [{},{}] was updated.", updateddIdentity.getUsername(), updateddIdentity.getId());
		// result
		return new DefaultEventResult<>(event, this);
	}
 
	@Override
	public int getOrder() {
		// notify event has their own process line - we can use default order
		return CoreEvent.DEFAULT_ORDER;
	}
}
  • Skip duplicate event in "the bigger window".
  • Support to persist confidential event properties.
  • Support retry failed events
  • Create FE component with entity state
  • Notification about failed events (or report)
  • Automatic role event doesn't propagate parent event id ⇒ processed by LRT.
