According to the weblogs.com XMLRPC ping API, the parameters to
weblogUpdates.extendedPing are as follows, in order:
- name of site
- URL of site or RSS feed
- the url of the page to be checked for changes
- the URL of an RSS, RDF, or Atom feed
- a name (or “tag”) categorizing your site content (optional)
However, WordPress sends only three parameters: site name, site URL, and RSS URL. This can be seen below:
$client->query('weblogUpdates.extendedPing', get_option('blogname'), $home, get_bloginfo('rss2_url') )
In other words, the
page to be checked for changes (which most software fills with the new or updated permalink) is instead filled with the feed URL, and the feed URL is not provided at all.
This bit of code seems to be in all recent versions of WordPress; b2 was apparently okay. I’ve only been able to find one page that even suggests it’s a bug. Have all of the ping services out there just accepted this and worked around it? Or does WordPress wind up sending two pings (a failed
extendedPing followed by a normal two-parameter
ping) for every attempt?
