Subject [jira] [Commented] (SLING-8309) Allow adding CommitHooks and EditorProviders dynamically from bundles
Date Wed, 13 Mar 2019 13:41:00 GMT

    [ https://issues.apache.org/jira/browse/SLING-8309?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16791701#comment-16791701

Michael Dürig commented on SLING-8309:
--------------------------------------

I would strongly advice against exposing commit hooks at the OSGi level. You are drilling
a whole right into the most sensible core of your content repository putting data consistency
and security at risk.

> Currently, {{OakSlingRepositoryManager}} uses a hard-coded list of {{CommitHook}} and
{{EditorProvider}} to be used by the Oak repository. This means that other than building a
patched version of {{OakSlingRepositoryManager}} there's no way to include a new commit observer.
Ideally, a single pseudo-\{{CommitHook}} and pseudo-\{{EditorProvider}} should be handled
to Oak, and these should just dynamically aggregate all the {{CommitHook}} and {{EditorProvider}}
instances registered in the {{Whiteboard}}.
> All the currently hardcoded components are already available in the whiteboard, so no
functionality will be lost, but this change will automatically enable support for {{mix:atomicCounter}}
via the {{AtomicCounterEditorProvider}} that's not used at the moment.
> The old behavior should still be available via a new configuration, {{OakSlingRepositoryManagerConfiguration#dynamic_components}}.
