Subject [jira] [Commented] (OAK-8166) Index definition with orderable property definitions with and without functions breaks index
Date Wed, 03 Apr 2019 13:49:04 GMT

    [ https://issues.apache.org/jira/browse/OAK-8166?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16808739#comment-16808739
] 

Nitin Gupta commented on OAK-8166:
----------------------------------

[~catholicon] - that was my first thought of the fix - to fix it in IndexDefinition where
it adds the both the property def nodes to aggListItems - but there I am not sure if the contents
of this list are used elsewhere and there this is what would work . Also technically this
list has 2 distinct items (the prop definition node) - it's just happens that the name for
these are the same (which they should be ) - so not sure if maybe not adding one instance
of one of the prop definition node or manipulating the name of one would be a good idea .

 

Maybe we can do some handling in the code that loops over Matchers (derived from the aggListItems)
- but then again - that too also would be ignoring the duplicate entries - just at an earlier
stage .

>             Project: Jackrabbit Oak
>          Issue Type: Bug
>          Components: indexing
>    Affects Versions: 1.8.12
>            Reporter: Tom Blackford
>            Priority: Major

> If an index definition contains the same orderable property with and without functions,
it will fail to index any node which contains that property. The failure will be logged as
[1].
> Steps to reproduce:
> * Configure index with the two property definitions shown at [2].
> * Refresh the index definition
> * Modify a node that falls under the definition - it will fail with the exception shown
at [1]
> * Modify the 'non-function' index definition to not be orderable (orderable=false)
> * Refresh the index definition
> * Modify the same node - note there is no exception.
> Thanks to [~catholicon] for assistance identifying root cause.
