Stefan Egli commented on OAK-5021:
----------------------------------

[~cziegeler], re your comment on JCR-4046 (which moved to OAK-5021 meanwhile):
{quote}First of all, you don't know if a pattern is targetting a file, assume
{noformat}/**/*.*{noformat}
{quote}
Are you expecting such a glob format to be supported via OAK-5019 ? The [GlobbingPathFilter|https://jackrabbit.apache.org/oak/docs/apidocs/org/apache/jackrabbit/oak/plugins/observation/filter/GlobbingPathFilter.html] defines globbing differently (more restricted).

> (Originally reported as JCR-4046, but moved to Oak as a result of introducing the OakEventFilter in OAK-5013. From the original description: )
> A file in JCR is represented by at least two nodes, the nt:file node and a child node named jcr:content holding the contents of the file (and metadata).
> This has the consequence that if the contents of a file changes, a change event of the jcr:content node is reported - but not of the nt:file node.
> This makes creating listeners listening for changes in files complicated, as you can't use the file name to filter  - especially with glob patterns (see JCR-4044 - now OAK-5019) this becomes troublesome.
> In addition, whenever you get a change for a jcr:content node, you have to check if the parent is a nt:file node and decide based on the result.
> It would be great to have a flag on the JackrabbitEventFilter to enable smarter reporting just for nt:files: if a property on jcr:content is changed, a change to the nt:file node is reported.
