wp_insert_post doesn't catch query failure

[lonnylot]

When we insert the post into the DB in wp-includes/post.php on line 2565 we check to see if the return is === false. $wpdb->insert will NEVER return false. It will only return -1 or the number of affected rows.

This is simply not true. $wpdb->insert() returns FALSE on error.

-1 is usually returned in an AJAX request, so something else is going on in your case.

$wpdb->insert() can return false, but it can also return mysql_affected_rows(), which on failure is -1.

I was looking at the code again and believe I was wrong w/ my initial statement. Before the call to mysql_affected_rows() there is a call to mysql_error() that will return false on an error. IMO this can be closed/deleted
