From dc09453a77f33c4dfdff306321ce93cf5fbd2d57 Mon Sep 17 00:00:00 2001 From: Brion Vibber Date: Mon, 8 Feb 2010 11:06:03 -0800 Subject: First steps on converting FeedSub into the pub/sub basis for OStatus communications: * renamed FeedSub plugin to OStatus * now setting avatar on subscriptions * general fixes for subscription * integrated PuSH hub to handle only user timelines on canonical ID url; sends updates directly * set $config['feedsub']['nohub'] = true to test w/ foreign feeds that don't have hubs (won't actually receive updates though) * a few bits of code documentation * HMAC support for verified distributions (safest if sub setup is on HTTPS) And a couple core changes: * minimizing HTML output for exceptions in API requests to aid in debugging * fix for rel=self link in apitimelineuser when id given This does not not yet include any of the individual subscription management (Salmon notifications for sub/unsub, etc) nor a nice UI for user subscriptions. Needs some further cleanup to treat posts as status updates instead of link references. --- .../extlib/XML/Feed/Parser/RSS11Element.php | 151 +++++++++++++++++++++ 1 file changed, 151 insertions(+) create mode 100755 plugins/OStatus/extlib/XML/Feed/Parser/RSS11Element.php (limited to 'plugins/OStatus/extlib/XML/Feed/Parser/RSS11Element.php') diff --git a/plugins/OStatus/extlib/XML/Feed/Parser/RSS11Element.php b/plugins/OStatus/extlib/XML/Feed/Parser/RSS11Element.php new file mode 100755 index 000000000..75918beda --- /dev/null +++ b/plugins/OStatus/extlib/XML/Feed/Parser/RSS11Element.php @@ -0,0 +1,151 @@ + + * @copyright 2005 James Stewart + * @license http://www.gnu.org/copyleft/lesser.html GNU LGPL 2.1 + * @version CVS: $Id: RSS11Element.php,v 1.4 2006/06/30 17:41:56 jystewart Exp $ + * @link http://pear.php.net/package/XML_Feed_Parser/ + */ + +/* + * This class provides support for RSS 1.1 entries.
