Subject [jira] Commented: (JCR-1428) Add API for selective bundle consistency check (Jackrabbit-specific)
Date Fri, 29 Feb 2008 11:46:51 GMT

    [ https://issues.apache.org/jira/browse/JCR-1428?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12573693#action_12573693

Alexander Klimetschek commented on JCR-1428:

> That's why one should login first and do the consistency check on WorkspaceImpl only.

I see, that's why you proposed to use the uuid of the jcr:system node for checking the versioning
pm. Didn't see that there is one WorkspaceImpl per session, hence possibly multiple WorkspaceImpl
per actual workspace, and not exact on WorkspaceImpl per workspace (jackrabbit's internal
architecture is sometimes hard to follow, because of the mix of JCR API and internal impl

The problem is that WorkspaceImpl has no access to the persistence managers stored in RepositoryImpl
(getWorkspaceInfo() and vMgr for versioning). I see only two solutions:

a) have a public method in RepositoryImpl so that WorkspaceImpl can access it -> no restriction
to admin user possible
b) introduce a special private interface that is passed to WorkspaceImpl in constructor that
allows access to PMs -> larger refactoring of central classes

Jukka and others, WDYT?

> Add a jackrabbit-specific API for doing a selective consistencyCheck, ie. on single nodes.
The current entire-workspace check can be very slow if there workspace is large enough. Also
it should be easy to write a tool to invoke that feature programmatically rather than by configuration
+ restart (see below).
> Existing Implementation:
> The current bundle consistencyCheck feature is enabled by setting a bundle PM parameter
and restarting Jackrabbit, it will then run upon startup (see JCR-972 for the only issue regarding
bundle consistency check). This check looks for broken parent-child relationships, ie. it
will remove any child node entries that reference non-existing parent nodes. For non-existing
parent UUIDs and other problems in bundles it will log those.
> Outlook:
> An advanced consistencyCheck could also check for non-existing version nodes and vice-versa
(see JCR-630), but this is not the focus of this issue and could be a later addition to the
