Can't use feed names as a slug with some permalink structures

[raena]

If you have date-based permalinks like yyyy/mm/dd/slug, and your slug happens to be the name of a feed, someone clicking its permalink will see a feed instead of the post.

You can see this in action on this post of Matthew Thomas', here:  http://mpt.net.nz/?p=36

The proper permalink for this can be seen in the URL on the headline, which is:  http://mpt.net.nz/archive/2004/09/30/atom

But clicking it gets an Atom feed for September 30th.

His site still uses an alpha from 1.3, but I've replicated this on a 1.5 install.

Eek! Still valid for WP 2.0.1

Recreation:

1. /%year%/%monthnum%/%day%/%postname%/ as permalink style
2. Create new entry with "Atom" as title
3. Access the entry
4. Get offered an atom feed to download

Maybe wordpress shouldn't allow you to have a slug with that name.

Hi Mark,

This is currently the only "blocker" bug open ;-)

Are you waiting on dev-feedback before preparing a patch? Is there something else needed before pursuing further? Is the bug really blocker?

Try this on for size.

I like Skeltoac's fix. That should do it.

We have a list of feeds in $wp_rewrite->feeds.

Updated to use $wp_rewrite->feeds

(In [4199]) Don't allow pages to have the same names as feeds to avoid rewrite collision. Props skeltoac. fixes #1231
