Not all WP_Query::query_vars get updated during WP_Query::get_posts()
|Reported by:||prettyboymp||Owned by:|
There is a lot of logic within the WP_Query::get_posts() method that fills in missing query vars with defaults and manipulates others based on the rest of the query. However, some of the final states for many of the variables aren't updated in the WP_Query::query_vars array. For example, the post type is lost as a local variable and post_status is used for building compiling mysql expressions, but never directly updated.
The result is that any plugins that want to recreate the query for another system, (ie, an external search provider) must directly copy much of the business logic that WP_Query::get_posts() has embedded in it in order to fill in for the incomplete query_var array.
