Problem: ========= One of the purge thread access the corrupted page and tries to remove from LRU list. In the mean time, other purge threads are waiting for same page in buf_wait_for_read(). Assertion(buf_fix_count == 0) fails for the purge thread which tries to remove the page from LRU list. Solution: ======== - Set the page id as FIL_NULL to indicate the page is corrupted before removing the block from LRU list. Acquire hash lock for the particular page id and wait for the other threads to release buf_fix_count for the block. - Added the error check for btr_cur_open() in row_search_on_row_ref(). |
