The actual installation in a repository works fine and both the install node as well as the parent /apps/acs-aem-commons node are of type nt:folder which is perfectly valid.

Agreed. Nothing about that install node looks unexpected to me. I'll have to look into to the TypeEditor to see how that constraint is evaluated. Can you paste the log lines for the scan goal related to Oak repository initialization? I wonder if the CND for nt:folder is somehow being redefined at runtime to not extend nt:hierarchyNode.

@kwin I'm not going to be able to run any builds myself until April 4 at the earliest (I'm between laptops until then). Do you know if there is a possibility that AutoSave can commit between adding a child node and setting its primary type when it is a folder that doesn't contain a .content.xml file?

kwin commented Apr 7, 2022

I don't think that the primary type is modified but is set to nt:folder during creation already by FileVault.

constraint violation appears to be detected here: https://github.com/apache/jackrabbit-oak/blob/73d9ec9823723bf2fa7741e557614cb89dc6962b/oak-core/src/main/java/org/apache/jackrabbit/oak/plugins/nodetype/TypeEditor.java#L487

curious. the install node appears to be defined as nt:unstructured:

@kwin oakpal is currently linked to version 3.4.4 of filevault, and the relevant logic is happening in FolderArtifactHandler.java:

See: https://github.com/apache/jackrabbit-filevault/blob/jackrabbit-filevault-3.4.4/vault-core/src/main/java/org/apache/jackrabbit/vault/fs/impl/io/FolderArtifactHandler.java#L82-L90

The order of extraction is:

  1. -content, with filter:
<workspaceFilter version="1.0">
    <filter root="/apps/acs-commons/config"/>
    <filter root="/apps/acs-commons/config.author"/>
    <filter root="/apps/acs-commons/config.publish"/>
</workspaceFilter>
  1. -ui.apps, with filter:
<filter root="/apps/acs-commons">
    <!-- ... includes /apps/acs-commons but excludes /apps/acs-commons/install -->
    <exclude pattern="/apps/acs-commons/install(/.*)?" />
</filter>
  1. -ui.content and everything else

The constraint violation on autosave is confusing, because it looks like /apps/acs-commons is imported as nt:folder, and then we attempt to import /apps/acs-commons/install as nt:unstructured.

But actually, the FolderArtifactHandler imports all of /apps, acs-commons, and install as nt:unstructured nodes during the -content package installation, because the -content workspace filter does not contain any of those paths, and because both jcr:root and nt:unstructured nodetypes specifies + * = nt:unstructured, every segment passes the parent.getPrimaryNodeType().canAddChildNode(dir.getRelativePath()) test.

When the -ui.apps subpackage is installed, the FolderArtifactHandler accepts /apps/acs-commons for a second time, but because it already exists, and because it is contained by the -ui.apps workspace filter, its primary node type is switched to FolderArtifactHandler.nodeType, which is set to nt:folder by default.

See: https://github.com/apache/jackrabbit-filevault/blob/jackrabbit-filevault-3.4.4/vault-core/src/main/java/org/apache/jackrabbit/vault/fs/impl/io/FolderArtifactHandler.java#L106-L108

It is the next autosave after this point that fails with the constraint violation, because the install folder still exists as a child of type nt:unstructured, which is now not allowed by the nt:folder nodetype of /apps/acs-commons.

The reason this isn't reproduced when installing the -content package in any Sling or AEM distribution is that /apps is universally pre-created by these products as an nt:folder node, which causes every child of /apps that is imported by filevault to fail the parent.getPrimaryNodeType().canAddChildNode(dir.getRelativePath()) test and therefore default to nt:folder all the way down.

I think the proper resolution is to configure oakpal-maven-plugin in acs-aem-commons/pom.xml with an /apps{nt:folder} forcedRoot, because that goes along with the other expected installation environment context that is already defined.

<forcedRoots>
    <forcedRoot>
        <path>/apps</path>
        <primaryType>nt:folder</primaryType>
    </forcedRoot>
</forcedRoots>

I'll submit a PR with this change and any other related fixes and request a review from you.

Thanks for the analysis. This behavior of FileVault was introduced with https://issues.apache.org/jira/browse/JCRVLT-417. Although some regressions were already fixed with https://issues.apache.org/jira/browse/JCRVLT-544 it seems we need another exclusion for nt:unstructured in FileVault to catch this edge case.
