Jan Lindström	a03dd94be8	MDEV-6936: Buffer pool list scan optimization Merged Facebook commit `617aef9f91` authored by Inaam Rana to InnoDB storage engine (not XtraDB) from https://github.com/facebook/mysql-5.6 WL#7047 - Optimize buffer pool list scans and related batch processing Reduce excessive scanning of pages when doing flush list batches. The fix is to introduce the concept of "Hazard Pointer", this reduces the time complexity of the scan from O(n*n) to O. The concept of hazard pointer is reversed in this work. Academically hazard pointer is a pointer that the thread working on it will declar such and as long as that thread is not done no other thread is allowe do anything with it. In this WL we declare the pointer as a hazard pointer and then if any thread attempts to work on it, it is allowed to do so but it has to a the hazard pointer to the next valid value. We use hazard pointer sol reverse traversal of lists within a buffer pool instance. Add an event to control the background flush thread. The background f thread wait has been converted to an os event timed wait so that it c signalled by threads that want to kick start a background flush when buffer pool is running low on free/dirty pages.	11 years ago

Inaam Rana	5352a76134	Bug#13704145: ELIMINATE LRU SCAN WHEN DROPPING A TABLE rb://942 approved by: Marko Makela We don't need to scan LRU for dropping AHI entries when DROPing a table. AHI entries are already removed when we free up extents for the btree.	14 years ago
Inaam Rana	358a31df43	Bug#11759044 - 51325: DROPPING AN EMPTY INNODB TABLE TAKES A LONG TIME WITH LARGE BUFFER POOL (Note: this a backport of revno:3472 from mysql-trunk) rb://845 approved by: Marko When dropping a table (with an .ibd file i.e.: with innodb_file_per_table set) we scan entire LRU to invalidate pages from that table. This can be painful in case of large buffer pools as we hold the buf_pool->mutex for the scan. Note that gravity of the problem does not depend on the size of the table. Even with an empty table but a large and filled up buffer pool we'll end up scanning a very long LRU list. The fix is to scan flush_list and just remove the blocks belonging to the table from the flush_list, marking them as non-dirty. The blocks are left in the LRU list for eventual eviction due to aging. The flush_list is typically much smaller than the LRU list but for cases where it is very long we have the solution of releasing the buf_pool->mutex after scanning 1K pages. buf_page_[set\|unset]_sticky(): Use new IO-state BUF_IO_PIN to ensure that a block stays in the flush_list and LRU list when we release buf_pool->mutex. Previously we have been abusing BUF_IO_READ to achieve this.	14 years ago
Jimmy Yang	95fa7fab3b	Fix bug #11830883 , SUPPORT "CORRUPTED" BIT FOR INNODB TABLES AND INDEXES. Also addressed issues in bug #11745133, where we could mark a table corrupted instead of crashing the server when found a corrupted buffer/page if the table created with innodb_file_per_table on.	14 years ago

Marko Mäkelä	67a0d9c0e0	Fix bit-rot left by the multiple buffer pools patch. Rename buf_pool_watch, buf_pool_mutex, buf_pool_zip_mutex to buf_pool->watch, buf_pool->mutex, buf_pool->zip_mutex in comments. Refer to buf_pool->flush_list_mutex instead of flush_list_mutex. Remove obsolete declarations of buf_pool_mutex and buf_pool_zip_mutex.	15 years ago
Marko Mäkelä	a8f2f7af32	Bug #56680 wrong InnoDB results from a case-insensitive covering index row_search_for_mysql(): When a secondary index record might not be visible in the current transaction's read view and we consult the clustered index and optionally some undo log records, return the relevant columns of the clustered index record to MySQL instead of the secondary index record. REC_INFO_DELETED_FLAG: Move the definition from rem0rec.ic to rem0rec.h. ibuf_insert_to_index_page_low(): New function, refactored from ibuf_insert_to_index_page(). ibuf_insert_to_index_page(): When we are inserting a record in place of a delete-marked record and some fields of the record differ, update that record just like row_ins_sec_index_entry_by_modify() would do. mysql_row_templ_t: Add clust_rec_field_no. row_sel_store_mysql_rec(), row_sel_push_cache_row_for_mysql(): Add the flag rec_clust, for returning data at clust_rec_field_no instead of rec_field_no. Resurrect the debug assertion that the record not be marked for deletion. (Bug #55626) buf_LRU_free_block(): Refactored from buf_LRU_search_and_free_block(). This is needed for the innodb_change_buffering_debug diagnostics. [UNIV_DEBUG \|\| UNIV_IBUF_DEBUG] ibuf_debug, buf_page_get_gen(), buf_flush_page_try(): Implement innodb_change_buffering_debug=1 for evicting pages from the buffer pool, so that change buffering will be attempted more frequently.	15 years ago
