[jira] [Resolved] (JCR-3376) TCK: SQLPathTest.testChildAxisRoot expects root node not in result

     [ https://issues.apache.org/jira/browse/JCR-3376?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Thomas Mueller resolved JCR-3376.
---------------------------------

    Resolution: Fixed

Revision 1359213 allows for optional nodes to be in the result. For the test SQLPathTest.testChildAxisRoot, the root node is now optional.

I tested with Jackrabbit Core (-PintegrationTesting) and with Oak (oak-jcr), with the test removed from the known.issues list in the pom.xml.

> The TCK test SQLPathTest.testChildAxisRoot runs the following SQL-1 query:
>     SELECT * FROM nt:base WHERE jcr:path LIKE '/%' AND NOT jcr:path LIKE '/%/%'
> It expects the result to be
>     /jcr:system, /testroot, /testdata
> It does not allow the implementation to return the root node ('/'). According to the specification, a JCR implementation may filter the root node, as noted by Randall Hauch - http://jackrabbit.510166.n4.nabble.com/TCK-SQLPathTest-testChildAxisRoot-td4655670.html - quote:
> "
> Section 6.6.5.1 ("jcr:like function") defines the semantics of the wildcard characters as generally used within LIKE predicates (and "jcr:like" in XPath):
> 	"As in SQL, the character '%' represents any string of zero or more 
> 	characters, and the character '_' (underscore) represents any 
> 	single character."
> while Section 8.5.2.2 ("Pseudo-property jcr:path") specifies the semantics "jcr:path" pseudo column and narrows the semantics of using LIKE with "jcr:path" in the second-to-last bullet point:
> 	"Predicates in the WHERE clause that test jcr:path are only required to 
> 	support the operators =, <> and LIKE. In the case of LIKE predicates, 
> 	support is only required for tests using the % wildcard character as a 
> 	match for a whole path segment (the part between two / characters) 
> 	or within index brackets...."
> Because the '%' matches only a whole path segment, the "/%" literal only matches paths that have at least one path segment, which means that it matches all descendants of the root node.
> "
> the specification says "In the case of LIKE predicates, support is only required for tests using the % wildcard character as a match for a whole path segment (the part between two / characters)..." but it doesn't specify it needs to do so.
