From a98a4f8bb56eacffff1765ff09dd29af26e5fc12 Mon Sep 17 00:00:00 2001 From: Thomas Bruederli Date: Wed, 27 Aug 2014 17:45:21 +0200 Subject: Remove 3rd party libs from our repository and define the dependencies in composer.json-dist. Also remove the ancient utf8 lib and replace it with 'Patchwork UTF-8 for PHP'. For direct git checkouts, copy composer.json-dist into composer.json and run `php composer.phar install` to install the dependencies. --- program/lib/Net/Socket.php | 686 --------------------------------------------- 1 file changed, 686 deletions(-) delete mode 100644 program/lib/Net/Socket.php (limited to 'program/lib/Net/Socket.php') diff --git a/program/lib/Net/Socket.php b/program/lib/Net/Socket.php deleted file mode 100644 index bf1d1bbcd..000000000 --- a/program/lib/Net/Socket.php +++ /dev/null @@ -1,686 +0,0 @@ - - * Chuck Hagenbuch - * - * @category Net - * @package Net_Socket - * @author Stig Bakken - * @author Chuck Hagenbuch - * @copyright 1997-2003 The PHP Group - * @license http://www.php.net/license/2_02.txt PHP 2.02 - * @link http://pear.php.net/packages/Net_Socket - */ - -require_once 'PEAR.php'; - -define('NET_SOCKET_READ', 1); -define('NET_SOCKET_WRITE', 2); -define('NET_SOCKET_ERROR', 4); - -/** - * Generalized Socket class. - * - * @category Net - * @package Net_Socket - * @author Stig Bakken - * @author Chuck Hagenbuch - * @copyright 1997-2003 The PHP Group - * @license http://www.php.net/license/2_02.txt PHP 2.02 - * @link http://pear.php.net/packages/Net_Socket - */ -class Net_Socket extends PEAR -{ - /** - * Socket file pointer. - * @var resource $fp - */ - var $fp = null; - - /** - * Whether the socket is blocking.
