#13391 closed defect (bug) (wontfix)

wpmu-terms.php fails if there are more terms in the blog's terms table than there are in wp_sitecategories

Reported by: mkanat's profile mkanat Owned by: donncha's profile donncha
Milestone: Priority: normal
Severity: normal Version: 2.9.2
Component: Administration Keywords: close
Focuses: Cc:


fix_blog_terms in wpmu-terms does this:

$maxterm = $wpdb->get_var( "SELECT max(cat_ID) FROM {$wpdb->sitecategories}" )

Then later it does this:

$term_id = $row->term_id + mt_rand( $maxterm+100, $maxterm+4000 );

However, if there are thousands of terms in the blog's terms table, and only a few terms in wp_sitecategories, this will result in term_ids that conflict with other term_ids in $wpdb->terms.

The simple (though probably not ideal) solution is to change the $maxterm line to:

$maxterm = max($wpdb->get_var( "SELECT max(cat_ID) FROM {$wpdb->sitecategories}" ),

$wpdb->get_var( "SELECT max(cat_ID) FROM {$wpdb->terms}" ) );

By the way, the reason this bug is marked as "major" severity is that running wpmu-terms.php on a blog with this problem causes the terms table to basically be fubar'ed beyond recovery.

Closing as wontfix due to this page not appearing in 3.0. Leaving the milestone attached however for record keeping purposes.
