wp_publish_post function does not check for unique postname in database

[mihirgosai]

If we use wp_publish_post function to change status of post, it does not check for unique postname (slug) from database. It can end up having two or more posts with same postname (slug).

Solution is to use code as below in wp-includes/post.php:
(function name: wp_publish_post)

$post->post_name = wp_unique_post_slug($post->post_name, $post->ID, 'publish', $post->post_type, $post->post_parent);

$wpdb->update( $wpdb->posts, array( 'post_status' => 'publish', 'post_name' => $post->post_name), array( 'ID' => $post->ID ) );
