Introduce WP_Theme, wp_get_themes(), and wp_get_theme() to replace get_themes(), get_theme(), get_theme_data(), current_theme_info(), and others. * Getters and Helpers: Introduces a series of methods to allow for easy generation of headers for display, and other theme metadata, including page templates. * Screenshots: Handles support for multiple screenshots. (see # Additional screenshots must be PNG and start with screenshot-2.png, and be sequential to be counted. see #19816. * Error Handling: Broken themes have a WP_Error object attached to them. * Caching: Introduces a wp_cache_themes_persistently filter (also in [20020]) to enable persistent caching of all filesystem and sanitization operations normally handled by WP_Theme (and formerly get_file_data() and get_themes()). Themes are cached individually and across five different cache keys for different data pieces. * Compatibility: A WP_Theme object is backwards compatible with a theme's array formerly returned by get_themes() and get_theme(), and an stdClass object formerly returned by current_theme_info(). * i18n/L10n: Theme headers are now localizable with proper Text Domain and Domain Path headers, like plugins. (Language packs may remove the requirement for headers.) For page templates, see #6007 (not fixed yet, but will be easy now). For headers, fixes #15858. * PHP and CSS files: New methods that fetch a list of theme files (for the theme editor) only on demand, rather than only loading them into memory. fixes #11214. Functions deprecated: * get_themes(), get_allowed_themes() and get_broken_themes() -- use wp_get_themes() * get_theme() and current_theme_info() -- use wp_get_theme() * get_site_allowed_themes() -- use WP_Theme::get_allowed_on_network() * wpmu_get_blog_allowedthemes() -- use WP_theme::get_allowed_on_site() see also [20016], [20018], [20019], [20020], [20021], [20022], [20025], [20026], [20027]. also fixes #19244. see #20103. git-svn-id: http://svn.automattic.com/wordpress/trunk@20029 1a063a9b-81f0-0310-95a4-ce76da25c4cd

switch_to_blog() and restore_current_blog() housekeeping. wp-includes/admin-bar.php: * Replace get_admin_url() and get_home_url() with admin_url() and home_url() and place them inside a switch/restore. Likewise replace current_user_can_for_blog() with current_user_can(). This avoids doing multiple switch restores. wp-includes/ms-blogs.php: * Deprecate the $validate argument to switch_to_blog(). This avoids a not very necessary call to get_blog_details(), possibly saving a few queries. * Use $_wp_switched and $_wp_switched_stack instead of $switched and $switched_stack to make it less likely these globals will be stomped. * Use GLOBALS to access blog_id and other globals. I've preferred this style lately since it makes it obvious a global is being used and avoids global blog_id being stomped by a local variable. * Lose some is_object() checks. wp_get_current_user() always returns an object, for example. * Call the new WP_Roles::reinit() method. wp-includes/class-wp-xmlrpc-server.php: * Replace current_user_can_for_blog() with current_user_can() and move it inside the switch/restore pair. This eliminates a switch/restore. wp-includes/capabilities.php: * Use array_keys() instead of $role => $data since $data is unused. I *think* this is a bit faster. * Introduce WP_Roles::reinit(). This reinitializes WP_Roles and is used after switch_to_blog() has already update the blog ID in the wpdb object. If a global roles array is being used instead of the db, reinit is skipped. * current_user_can_for_blog() now does a switch/restore. It didn't before meaning it could be reinitializing the user with the wrong role information for the current blog. wp-includes/ms-settings.php: * Define $_wp_switched_stack and $_wp_switched. This way switch_to_blog() and restore_current_blog() can rely on it being set. wp-settings.php: * Instantiate the WP_Roles global. This was it is always defined during init. To remove the WP_Roles checks from WP_Role and WP_User this would probably have to move before plugins are loaded, which might not be a good thing. wp-includes/functions.php: * Update wp_upload_dir() to reference _wp_switched. git-svn-id: http://core.svn.wordpress.org/trunk@21485 1a063a9b-81f0-0310-95a4-ce76da25c4cd
