AtomPub Doesn't Work When Using Clean URLs

[josephscott]

When trying to get a post collection a client will ask for wp-app.php/posts which works fine with the regular ?p=1 style URLs, but will return zero posts when clean URLs are turned on. After comparing successful requests with failed ones, it looks like WordPress is marking wp-app.php/posts requests as a 404 so it doesn't bother to do the post query to fetch recent post data. From the client point of view it looks like the blog has no posts.

The solution I came up with checks the $req_uri value to see if it's equal to wp-app.php. If it is then it breaks out of the rewrite match loop. This worked for both the default ?p=1 style URLs and clean URLs.

Just to note, it looks like AtomPub support for clean URL blogs has not been working for quite awhile. It doesn't work in 2.5.1 and appears to have broke during the r5951 changes back at the end of August 2007.

(In [8263]) Don't try to match rewrite rules against AtomPub requests. Props josephscott. fixes #7249
