Request for a disconnect method

[ghost]

Hi,

Time to time this line causes error below. I had to remove suppression and catch it with error_get_last function otherwise it throws this exception.

{"type":2,"message":"ftp_chdir(): Timeout.","file":"/vendor/knplabs/gaufrette/src/Gaufrette/Adapter/Ftp.php","line":348}

When it happens I have to explicitly set connection variable to null by calling the temporary method below and try FTPing my file again which solves the problem.

public function disconnect()
{
    $this->connection = null;
}

Suggestion:
We need a way of manually disconnecting from the open/currently used adapter so that when we catch this exception we can assume that it was a timeout issue or something else then try to FTPing our file one more time before giving up. Temporary solution below solves my problem but I have to fork and modify the library for such a small fix.

while ($i < 2) {
    try {
        $this->adapter->write($path, $fileContent);

        return;
    } catch (RuntimeException $e) {
        $this->adapter->disconnect();
    }

    ++$i;
}

throw new AnotherException('Error message');

Thanks
