["ASF subversion and git services (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/NIFI-15296?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=18043256#comment-18043256 ] 

ASF subversion and git services commented on NIFI-15296:
--------------------------------------------------------

Commit 3c0c64619bb29e06516308491331ba4e9c20caae in nifi's branch refs/heads/main from David Handermann
[ https://gitbox.apache.org/repos/asf?p=nifi.git;h=3c0c64619b ]

NIFI-15296 Fixed enabling Controller Services with dependencies

- Filtered list of required Controller Services based on whether the property descriptor has satisfied dependencies to avoid enabling unnecessary referenced Controller Services
- Added unit test with Primary Controller Service referencing Secondary Controller Service depending on specified properties

Signed-off-by: Pierre Villard <pi...@gmail.com>

This closes #10603.

> The framework {{ControllerServiceNode}} interface includes the {{getRequiredControllerServices}} method, which is responsible for returning a flattened list of Controller Services that must be enabled before the current Controller Service can be enabled. At the time of initial implementation, the framework did not support the concept of dependent properties, so the standard implementation returns every {{ControllerServiceNode}} configured through a property values. With the introduction of dependent properties, however, it is possible for one Controller Service to be configured with a property referencing another Controller Service that is not needed for actual operation.
> Following the strategy of framework handling for other dependent property values, referenced Controller Services with unsatisfied dependencies should not be included in the list of required Controller Services. With correct filtering, such Controller Services should not be enabled as part of enabling the primary Controller Service in which they are referenced.
