WPCOMism in xmllrpc.php

[donncha]

The check for site_id on line 432 of xmlrpc.php is a piece of legacy code from WordPress.com and has been taken out in WordPress MU.

That foreach() loop is also missing a restore_current_blog() call, the complement of switch_to_blog(). It should be added immediately after the definition of $is_admin.

Those functions don't exist in WP.

Here's an untested patch based on a brief discussion with Donncha.

[ryan]

get_blogs_of_user() doesn't exist for WP. Nor do the switch and restore functions.

[ryan]

Ah, I see. We test for is_site_admin() to short-circuit for WP. The fix is so WPMU picks it up on merge.
