Support getting versioned resources by using uri path parameters
----------------------------------------------------------------
Key: SLING-848
URL: https://issues.apache.org/jira/browse/SLING-848
Project: Sling
Issue Type: New Feature
Components: JCR Install
Affects Versions: JCR Resource 2.0.2
Reporter: Carsten Ziegeler
Assignee: Carsten Ziegeler
Fix For: JCR Resource 2.0.4
Getting versioned content should be support thorough uri path parameters, like
/something/hello;v=1.1
For jcr based resources the value of the version should either point to a
version name or label.
In order to not change our existing apis, we introduce a new utility method
which removes all uri path parameters
and returns a map of these. Every resource provider could use this utility
method and then decide to act on these
parameters.
If a requested version does not exists, a 404 is returned.
If the requested node does not directly point to a versionable node, the
algorithm checks the parent hierarchy until a versionable node is found, and
tries to get the version of this node and then goes down the path again. If the
versionable node does not have the requested version or the child, a 404 is
returned.
