Problem: ======== During ALTER TABLE ... IGNORE, a partial rollback on duplicate key error resets trx->undo_no to 0. The subsequent insert then enters the undo rewrite block with undo_no == 0, hitting the assertion that expected undo_no == 1. Solution: ========= Partial rollback which truncates the last insert undo record via trx_undo_truncate_end(), which rewrites TRX_UNDO_PAGE_FREE on the page. By checking trx->undo_no as part of the rewrite predicate, InnoDB correctly skips the rewrite logic after partial rollback. trx_undo_report_row_operation(): Pre-compute the full predicate (clear_ignore) before trx_undo_assign_low(), since old_offset and top_offset are not modified by that call. trx_undo_rewrite_ignore(): Extract the rewrite body into a separate ATTRIBUTE_COLD ATTRIBUTE_NOINLINE static function. |
