EiffelActivityTriggeredEvent (ActT)

The EiffelActivityTriggeredEvent declares that a certain activity - typically a build, test or analysis activity - has been triggered by some factor. Note that this is crucially different from the activity execution having started (as declared by EiffelActivityStartedEvent).

In a situation where execution follows immediately upon triggering these two events should be sent together. Where that is not the case (e.g. due to queuing) the time delta between EiffelActivityTriggeredEvent and EiffelActivityStartedEvent constitutes the queue time.

Data Members

data.name

Type: String
Required: Yes
Description: The name of the activity. Uniqueness is not required or checked, but is useful.

data.categories

Type: String[]
Required: No
Description: Any categorization of the activity. This can be used to group multiple similar activities for analysis and visualization purposes. Example usage is to label the similar but unique build activities of all the components of system X as "System X Component Build" (whereas the name would be e.g. "System X Component Y Build").

data.triggers

Type: Object[]
Required: No
Description: The circumstances triggering the activity.

data.triggers.type

Type: String
Required: Yes
Legal values: MANUAL, EIFFEL_EVENT, SOURCE_CHANGE, TIMER, OTHER
Description: The type of trigger.
MANUAL signifies that the activity was manually triggered.
EIFFEL_EVENT signifies that the activity was triggered by one or more Eiffel events. These events should be represented via CAUSE links.
SOURCE_CHANGE signifies that the activity was triggered as a consequence of a detected source change not represented by Eiffel events.
TIMER signifies that the activity was triggered by a timer.
OTHER signifies any other triggering cause.

data.triggers.description

Type: String
Required: No
Description: A description of the trigger.

data.executionType

Type: String
Required: No
Legal values: MANUAL, SEMI_AUTOMATED, AUTOMATED, OTHER
Description: The type of execution (often related to, but ultimately separate from, data.triggers.type).

Links

CAUSE

Required: No
Legal targets: Any
Multiple allowed: Yes
Description: Identifies a cause of the event occurring. SHOULD not be used in conjunction with CONTEXT: individual events providing CAUSE within a larger context gives rise to ambiguity. It is instead recommended to let the root event of the context declare CAUSE.

CONTEXT

Required: No
Legal targets: EiffelActivityTriggeredEvent, EiffelTestSuiteStartedEvent
Multiple allowed: No
Description: Identifies the activity or test suite of which this event constitutes a part.

FLOW_CONTEXT

Required: No
Legal targets: EiffelFlowContextDefinedEvent
Multiple allowed: Yes
Description: Identifies the flow context of the event: which is the continuous integration and delivery flow in which this occurred – e.g. which product, project, track or version this is applicable to.

Meta Members

meta.id

Type: String
Format: UUID
Required: Yes
Description: The unique identity of the event, generated at event creation.

meta.type

Type: String
Format: An event type name
Required: Yes
Description: The type of event. This field is required by the recipient of the event, as each event type has a specific meaning and a specific set of members in the data and links objects.

meta.version

Type: String
Format: Semantic Versioning 2.0.0
Required: Yes
Description: The version of the event type. This field is required by the recipient of the event to interpret the contents. Please see Versioning for more information.

meta.time

Type: Integer
Format: Milliseconds since epoch.
Required: Yes
Description: The event creation timestamp.

meta.tags

Type: String[]
Format: Free text
Required: No
Description: Any tags or keywords associated with the events, for searchability purposes.

meta.source

Type: Object
Format:
Required: No
Description: A description of the source of the event. This object is primarily for traceability purposes, and while optional, some form of identification of the source is HIGHLY RECOMMENDED. It offers multiple methods of identifying the source of the event, techniques which may be select from based on the technology domain and needs in any particular use case.

meta.source.domainId

Type: String
Format: Free text
Required: No
Description: Identifies the domain that produced an event. A domain is an infrastructure topological concept, which may or may not corresponds to an organization or product structures. A good example would be Java packages notation, ex. com.mycompany.product.component or mycompany.site.division. Also, keep in mind that all names are more or less prone to change. Particularly, it is recommended to avoid organizational names or site names, as organizations tend to be volatile and development is easily relocated. Relatively speaking, product and component names tend to be more stable and are therefore encouraged, while code names may be an option. You need to decide what is the most sensible option in your case.

meta.source.host

Type: String
Format: Hostname
Required: No
Description: The hostname of the event sender.

meta.source.name

Type: String
Format: Free text
Required: No
Description: The name of the event sender.

meta.source.serializer

Type: Object
Format:
Required: No
Description: The GAV coordinates of the serializer software used to construct the event.

meta.source.serializer.groupId

Type: String
Format: groupId
Required: Yes
Description: The groupId of the serializer software.

meta.source.serializer.artifactId

Type: String
Format: artifactId
Required: Yes
Description: The artifactId of the serializer software.

meta.source.serializer.version

Type: String
Format: version
Required: Yes
Description: The version of the serializer software.

meta.source.uri

Type: String
Format: URI
Required: No
Description: The URI of, related to or describing the event sender.

meta.security

Type: Object
Format:
Required: No
Description: An optional object for enclosing security related information, particularly supporting data integrity. See Security for further information.

meta.security.sdm

Type: Object
Format:
Required: No
Description: An optional object for properties supporting the Strong Distribution Model. Note that this only addressed the integrity of the Eiffel event, not its confidentiality or availability.

meta.security.sdm.authorIdentity

Type: String
Format:
Required: Yes
Description: The identity of the author of the event. This property is intended to enable the recipient to look up the appropriate public key for decrypting the digest and thereby verifying author identity and data integrity. The format of the author identity varies depending on the key infrastructure solution used. Note that this requires the presence of a Trusted Authority (TA) which the recipient can query for the correct public key. The identity and location of the TA must never be included in the event itself, as this would compromise the security of the solution.

meta.security.sdm.encryptedDigest

Type: String
Format:
Required: Yes
Description: The encrypted digest. The cryptographic hash function and the decryption algorithm to use, similarly to the Trusted Authority (TA), must be known to the recipient. Note that the digest of the entire event is affected by the value of this property. For this reason the input to the hash function SHALL be the entire event unaltered in all parts except for this property, which SHALL be replaced by an empty string.
