ZF-8262: Zend_Ldap_Collection fails to check constraints, fails to return first result with current without seeking

Issue Type: Bug Created: 2009-11-09T13:03:39.000+0000 Last Updated: 2009-11-10T04:01:43.000+0000 Status: Resolved Fix version(s): - 1.10.0 (27/Jan/10)

Zend_Ldap_Collection has a protected var _currentNumber that defaults to -1. Calling current() on a fresh Zend_Ldap_Collection returned by a search will result in Zend_Ldap_Collection searching for index -1 in an array that should be indexed with positive numbers. This then falls through to Zend_Ldap_Collection_Default where a similar error is made, all in all resulting in the inability to call current() without seeking first. There is a function getFirst(), however I would expect current() to return either NULL if no result exists (as in Zend_Db_Table_Rowset_Abstract) or the first result if I do not seek.

Fixed in trunk (r18921)

Removed dependency on calling Zend_Ldap_Collection::rewind() before using Zend_Ldap_Collection::current() and/or Zend_Ldap_Collection::key(). Zend_Ldap_Collection::rewind() will be called internally if iteration has not been started yet.

Added Zend_Ldap_Collection::getInnerIterator() to return the underlying Zend_Ldap_Collection_Iterator_Default.

Added Zend_Ldap_Collection::dn() to accompany Zend_Ldap_Collection::key(). The latter returns the numerical index of the current result item within the result set, the former returns its DN.
