This fix does not remove the underlying cause of the assertion failure. It just works around the problem, allowing a corrupted secondary index to be fixed by DROP INDEX and CREATE INDEX (or in the worst case, by re-creating the table). ibuf_delete(): If the record to be purged is the last one in the page or it is not delete-marked, refuse to purge it. Instead, write an error message to the error log and let a debug assertion fail. ibuf_set_del_mark(): If the record to be delete-marked is not found, display some more information in the error log and let a debug assertion fail. row_undo_mod_del_unmark_sec_and_undo_update(), row_upd_sec_index_entry(): Let a debug assertion fail when the record to be delete-marked is not found. buf_page_print(): Add ut_ad(0) so that corruption will be more prominent in stress testing with debug binaries. Add ut_ad(0) here and there where corruption is noticed. btr_corruption_report(): Display some data on page_is_comp() mismatch. btr_assert_not_corrupted(): A wrapper around btr_corruption_report(). Assert that page_is_comp() agrees with the table flags. rb:911 approved by Inaam Rana |
