[jira] [Created] (OAK-3507) Virtual index rows should have paths as 'null'

Vikas Saurabh created OAK-3507:
----------------------------------

             Summary: Virtual index rows should have paths as 'null'
                 Key: OAK-3507
                 URL: https://issues.apache.org/jira/browse/OAK-3507
             Project: Jackrabbit Oak
          Issue Type: Improvement
          Components: query
            Reporter: Vikas Saurabh
            Priority: Minor


While discussing OAK-3156, it was decided that virtual rows would have returned path as {{null}}. Opening this issue to let OAK-3156 be resolved as status quo on value being returned by virtual rows.

Note: Having {{null}} paths for virtual rows is semantically correct as there is no defined meaning of a path for those rows. But it brings in some backward incompatibility issue:
* existing queries which would have some {{... AND jcr:path='/'}} would not work anymore
* xpaths has path built in implicitly, so xpath need to be un-supported

PS: Do look at comments on OAK-3156 to get more details into how/why did we arrive here.
