Subject [jira] Created: (DIRGROOVY-7) Support for "returning attributes" in searches
Date Thu, 15 Apr 2010 17:41:50 GMT
Support for "returning attributes" in searches
----------------------------------------------

                 Key: DIRGROOVY-7
                 URL: https://issues.apache.org/jira/browse/DIRGROOVY-7
             Project: Directory Groovy LDAP
          Issue Type: Improvement
            Reporter: Grégory Joseph
            Assignee: Stefan Zoerner


While the {{o.a.d.groovyldap.Search}} currently holds an {{attrs}} array for these, and they
are set accordingly on the SearchControls instance, 2 things are missing to make it useful:
* support for this in the Map-based constructor
* {{o.a.d.groovyldap.jndi.DirContextToMapObjectFactory}} should use these attributes (they're
passed as {{attrs}} to the {{getObjectInstance}} instance) instead of getting all attributes
from the current record.

This would have two benefits:
* a presumed performance gain ? (I've always assumed that's one of the reasons for passing
"returning attributes" to searches)
* the ability to retrieve operational attributes such as 'createTimestamp' and 'modifyTimestamp'
which are not retrieved when not specified explicitly.

I'll attach a patch that makes the following code work:
{code}
def LDAP ldap = LDAP.newInstance('ldap://localhost/dc=example,dc=com')
ldap.search(
        'base': 'ou=users',
        'filter': '(objectClass=posixAccount)',
        'attrs': ['uid','cn',
                'createTimestamp', 'creatorsName',
                'modifyTimestamp', 'modifiersName'
        ]
).each {
    println """${it.uid}: ${it.cn}
    mod: ${it.modifyTimestamp} (${it.creatorsName})
    cre: ${it.createTimestamp} (${it.modifiersName})"""
}{code}
(with the current groovyldap, the "mod" and "cre" lines print nulls)
