Bug in Zend_Cache_Backend_Apc::getIds()

[jianzhong]

The getIds() method is looking for an array item indexed with 'info' in the array returned by calling apc_cache_info(), but the key doesn't exist. The key name has changed to 'key', instead of 'info'. See the apc_cache_info() return value below.

array(14) {
  ["nslots"] => int(4099)
  ["ttl"] => int(0)
  ["nhits"] => float(1)
  ["nmisses"] => float(0)
  ["ninserts"] => float(1)
  ["nentries"] => int(1)
  ["nexpunges"] => float(0)
  ["stime"] => int(1386244867)
  ["mem_size"] => float(656)
  ["file_upload_progress"] => int(1)
  ["memory_type"] => string(4) "mmap"
  ["cache_list"] => array(1) {
    [0] => array(9) {
      ["key"] => string(5) "test1"
      ["ttl"] => int(3600)
      ["nhits"] => float(1)
      ["mtime"] => int(1386244910)
      ["ctime"] => int(1386244910)
      ["dtime"] => int(0)
      ["atime"] => int(1386244910)
      ["ref_count"] => int(0)
      ["mem_size"] => int(656)
    }
  }
  ["deleted_list"] => array(0) {
  }
  ["slot_distribution"] => array(1) {
    [1140] => int(1)
  }
}

My php version is 5.5.3, and has APCu module enabled.

In Apc.conf:

public function getIds()
{
    $res = array();
    $array = apc_cache_info('user', false);
    var_dump($array['cache_list']);
    $records = $array['cache_list'];
    foreach ($records as $record) {
            $res[] = $record['info'];
    }
    return $res;
}

I fixed it temporarily like this:

public function getIds()
{
    $res = array();
    $array = apc_cache_info('user', false);
    var_dump($array['cache_list']);
    $records = $array['cache_list'];
    foreach ($records as $record) {
        if (isset($record['info'])) {
            $res[] = $record['info'];
        } else {
            $res[] = $record['key'];
        }
    }
    return $res;
}

But cleaner solution would probably be to use APCIterator instead of relying on the apc_cache_info structure which can change.
