serverList（）只返回100个结果

Question

I'm trying to write a bit of code to inventory our OpenStack deployment, and I've run into an issue where serverList() only ever returns 100 results instead of the 600+ I'm expecting. I've reviewed the documentation and a bit of the source, and as far as I can tell there's no reason that this should be happening as the PaginatedIterator should be doing its pagination transparently.

There are no errors or warning either generated in my code, or logged on my controller [that I can find]. I am using php-opencloud v1.12 via composer.

use OpenCloud\OpenStack;
$client = new OpenStack('http://1.2.3.4:5000/v2.0/', array(
    'username'  => 'admin',
    'password'  => 'hunter2',
    'tenantName'=> 'admin',
));
$service = $client->computeService('nova', 'RegionOne');

$stmt = $dbh->prepare('INSERT INTO servers VALUES (?,?)');
/* foreach($service->serverList() as $server) {
    $stmt->execute([$server->id, $server->name]);
} // neither method works */
$list = $service->serverList();
while( $list->valid() ) {
    $server = $list->current();
    $stmt->execute([$server->id, $server->name]);
    $list->next();
}
echo "\n";
var_dump($dbh->query('SELECT * FROM servers')->fetchAll(PDO::FETCH_ASSOC));

分页的默认限制为100.可以使用更高的限制覆盖此限制，如下所示：

$list = $service->serverList(null, array('limit' => 700));
