| 141 | * not exploitable, but there is no reason not to prepare it: INDEX_NAME and |
| 142 | * TABLE_NAME are compared as values, so %s is the correct placeholder. |
| 143 | * |
| 144 | * 2. The result came from $wpdb->query(), which returns false when the query fails, |
| 145 | * and the old "return ( $result !== 0 ) ? 1 : 0" read that false as 1, i.e. "the |
| 146 | * index is already there". A failing lookup therefore reported the table as |
| 147 | * optimized: AHSC_DBOPT_Optimize() skipped creating the index and |
| 148 | * AHSC_DBOPT_Check() declared everything fine. get_var() returns null on failure, |
| 149 | * which is distinguishable from a legitimate count of zero. |
| 150 | * |
| 151 | * 3. INFORMATION_SCHEMA spans every schema on the server, and the query had no |
| 152 | * TABLE_SCHEMA filter. On shared MySQL with several installations using the same |
| 153 | * table prefix, an index belonging to another database counted as ours. |
