Old Slug Redirect fails with Close Old Comments enabled

[ShaneF]

I was have a problem with Old slug redirects, and passed most of them off as server errors. But that is not the case.

Currently on the site, I have a custom structure for posts: /blog/%year%/%monthnum%/%day%/%postname%/

Remember that 'blog' is a static page holding the posts as well. The example to explain the problem is this.

Currently, I have this post, ​http://bugssite.org/blog/2008/07/28/left-4-dead-preview/. As you can see it goes to the post. The old slug for this post was "​http://bugssite.org/blog/2008/07/28/left-4-dead/" but if you goto this link it shows the "single" page layout with nothing. It's not a '404' error as needed for old_slug checking.

I think the reason is that because /blog/ is a 'static page' and it is valid. If you do "​http://bugssite.org/2008/07/28/left-4-dead/" or even "​http://bugssite.org/left-4-dead/" it redirects to the correct page of "​http://bugssite.org/blog/2008/07/28/left-4-dead-preview/"

Judging from the IRC chat, I take is_404 is not being set?

If the issue is that the 404 is not being set, then that'd have the flow on effect of the redirection code not kicking in i believe.

I just confirmed it works as expected for me using the same permalink structure.

At first, I had an issue with a custom rewrite rule i've got in place, But once i delt with that, The redirection works for me as expected.

Throw some debug lines in around these locations:

wp_old_slug_redirect (): query.php line 2600
WP Class: classes line 210

to see what rewrite rule's being matched, and all that, you might find something funky in your rewrite rules.

Is blog a page? I think that is were the is_404 has it's problem.

404 Error Returns: 0

$wp_query->query_vars['name'] is: left-4-dead

Ok. The reason why it will not work is because 'Close old posts after X" was enabled. Once it was disabled it worked fine.

[DD32]

    [posts] => Array
        (
            [0] => stdClass Object
                (
                    [comment_status] => closed
                    [ping_status] => closed
                )

        )

To me, It looks like the close comments on old posts is kicking in and breaking it, ShaneF confirmed on IRC that disabling that functionality allowed it to work.

attachment 7976.diff added.

• Returns early if $posts is empty
• Untested locally; ShaneF, feel like testing for me?

[ShaneF]

Works like a charm.
