Michael Widenius	29b751c796	Updated comments as part of code review .bzr-mysql/default.conf: 5.2 -> 5.3 sql/handler.h: Updated comments.	15 years ago
Michael Widenius	3631146442	Original idea from Zardosht Kasheff to add HA_CLUSTERED_INDEX - Added a lot of code comments - Updated get_best_ror_intersec() to prefer index scan on not clustered keys before clustered keys. - Use HA_CLUSTERED_INDEX to define if one should use HA_MRR_INDEX_ONLY - For test of using index or filesort to resolve ORDER BY, use HA_CLUSTERED_INDEX flag instead of primary_key_is_clustered() - Use HA_TABLE_SCAN_ON_INDEX instead of primary_key_is_clustered() to decide if ALTER TABLE ... ORDER BY will have any effect. sql/ha_partition.h: Added comment with warning for code unsafe to use with multiple storage engines at the same time sql/handler.h: Added HA_CLUSTERED_INDEX. Documented primary_key_is_clustered() sql/opt_range.cc: Added code comments Updated get_best_ror_intersec() to ignore clustered keys. Optimized away cpk_scan_used and one instance of current_thd (Simpler code) Use HA_CLUSTERED_INDEX to define if one should use HA_MRR_INDEX_ONLY sql/sql_select.cc: Changed comment to #ifdef For test of using index or filesort to resolve ORDER BY, use HA_CLUSTERED_INDEX flag instead of primary_key_is_clustered() (Change is smaller than what it looks beause of indentation change) sql/sql_table.cc: Use HA_TABLE_SCAN_ON_INDEX instead of primary_key_is_clustered() to decide if ALTER TABLE ... ORDER BY will have any effect. storage/innobase/handler/ha_innodb.h: Added support for HA_CLUSTERED_INDEX storage/innodb_plugin/handler/ha_innodb.cc: Added support for HA_CLUSTERED_INDEX storage/xtradb/handler/ha_innodb.cc: Added support for HA_CLUSTERED_INDEX	15 years ago

Michael Widenius	6da8ac5f71	Added option "AND DISABLE CHECKPOINT" to "FLUSH TABLES WITH READ LOCK" This makes it possible to do safe multi volume snapshots as long as one snapshots the volume with the transaction logs last. include/mysql_com.h: Added REFRESH_CHECKPOINT mysql-test/r/flush.result: Added test of new FLUSH TABLES syntax + calls to checkpoint_status handler calls mysql-test/t/flush.test: Added test of new FLUSH TABLES syntax + calls to checkpoint_status handler calls sql/handler.cc: Added code to call checkpoint_state for all handlertons that supports it sql/handler.h: Added new checkpoint_state() handlerton call to temporarly disable checkpoints. sql/lex.h: Added CHECKPOINT keyword sql/sql_yacc.yy: Added support for FLUSH TABLES WITH READ LOCK AND DISABLE CHECKPOINT storage/maria/ha_maria.cc: Added handlerton call to disable checkpoints. storage/maria/ma_checkpoint.c: Don't do checkpoint if checkpoints are disabled. storage/maria/ma_static.c: Added maria_checkpoint_disabled storage/maria/maria_def.h: Added maria_checkpoint_disabled storage/xtradb/handler/ha_innodb.cc: Added handlerton call to disable checkpoints. storage/xtradb/include/log0log.h: Added option to log_checkpoint() to allow one to ignore not critical checkpoints during the time checkpoints are disabled. storage/xtradb/log/log0log.c: Added code to allow one to disable checkpoints during a FLUSH TABLES ... DISABLE CHECKPOINT This was done by adding a new argument to log_checkpoint() which tells us when the checkpoint is called by srv_master_thread (which are safe to ignore) storage/xtradb/srv/srv0srv.c: Tell log_checkpoint() that checkpoints from srv_master_thread() are safe to ignore (will just delay recovery time a bit).	15 years ago
Sergey Petrunya	d4ce827226	Amend the previous cset: Make EXPLAIN better at displaying MRR/BKA: - Update all .result files - Extra comments	15 years ago
Sergey Petrunya	997445bc8e	Make EXPLAIN better at displaying MRR/BKA: - "Using MRR" is no longer shown with range access. - Instead, both range and BKA accesses will show one of the following: = "Rowid-ordered scan" = "Key-ordered scan" = "Key-ordered Rowid-ordered scan" depending on whether DS-MRR implementation will do scan keys in order, rowids in order, or both. - The patch also introduces a way for other storage engines/MRR implementations to pass information to EXPLAIN output about the properties of employed MRR scans.	15 years ago

Magne Mahre	9ff72a1acf	Bug#11900714 REMOVE LGPL LICENSED FILES IN MYSQL 5.1 The LGPL license is used in some legacy code, and to adhere to current licensing polity, we remove those files that are no longer used, and reorganize the remaining LGPL code so it will be GPL licensed from now on. Note: This patch only removed LGPL licensed files in MySQL 5.1, and is the second of a set of patches to remove LGPL from all trees. (See Bug# 11840513 for details)	15 years ago
Mattias Jonsson	e0887df8e1	Bug#11766249 bug#59316: PARTITIONING AND INDEX_MERGE MEMORY LEAK When executing row-ordered-retrieval index merge, the handler was cloned, but it used the wrong memory root, so instead of allocating memory on the thread/query's mem_root, it used the table's mem_root, resulting in non released memory in the table object, and was not freed until the table was closed. Solution was to ensure that memory used during cloning of a handler was allocated from the correct memory root. This was implemented by fixing handler::clone() to also take a name argument, so it can be used with partitioning. And in ha_partition only allocate the ha_partition's ref, and call the original ha_partition partitions clone() and set at cloned partitions. Fix of .bzrignore on Windows with VS 2010	15 years ago

Davi Arnaut	0f9ddfa9d8	Bug#42733: Type-punning warnings when compiling MySQL -- strict aliasing violations. One somewhat major source of strict-aliasing violations and related warnings is the SQL_LIST structure. For example, consider its member function `link_in_list` which takes a pointer to pointer of type T (any type) as a pointer to pointer to unsigned char. Dereferencing this pointer, which is done to reset the next field, violates strict-aliasing rules and might cause problems for surrounding code that uses the next field of the object being added to the list. The solution is to use templates to parametrize the SQL_LIST structure in order to deference the pointers with compatible types. As a side bonus, it becomes possible to remove quite a few casts related to acessing data members of SQL_LIST. sql/handler.h: Use the appropriate template type argument. sql/item.cc: Remove now-unnecessary cast. sql/item_subselect.cc: Remove now-unnecessary casts. sql/item_sum.cc: Use the appropriate template type argument. Remove now-unnecessary cast. sql/mysql_priv.h: Move SQL_LIST structure to sql_list.h Use the appropriate template type argument. sql/sp.cc: Remove now-unnecessary casts. sql/sql_delete.cc: Use the appropriate template type argument. Remove now-unnecessary casts. sql/sql_derived.cc: Remove now-unnecessary casts. sql/sql_lex.cc: Remove now-unnecessary casts. sql/sql_lex.h: SQL_LIST now takes a template type argument which must match the type of the elements of the list. Use forward declaration when the type is not available, it is used in pointers anyway. sql/sql_list.h: Rename SQL_LIST to SQL_I_List. The template parameter is the type of object that is stored in the list. sql/sql_olap.cc: Remove now-unnecessary casts. sql/sql_parse.cc: Remove now-unnecessary casts. sql/sql_prepare.cc: Remove now-unnecessary casts. sql/sql_select.cc: Remove now-unnecessary casts. sql/sql_show.cc: Remove now-unnecessary casts. sql/sql_table.cc: Remove now-unnecessary casts. sql/sql_trigger.cc: Remove now-unnecessary casts. sql/sql_union.cc: Remove now-unnecessary casts. sql/sql_update.cc: Remove now-unnecessary casts. sql/sql_view.cc: Remove now-unnecessary casts. sql/sql_yacc.yy: Remove now-unnecessary casts. storage/myisammrg/ha_myisammrg.cc: Remove now-unnecessary casts.	16 years ago

Sergey Vojtovich	4aa36ee7b6	BUG#39053 - UNISTALL PLUGIN does not allow the storage engine to cleanup open connections It was possible to UNINSTALL storage engine plugin when binding between THD object and storage engine is still active (e.g. in the middle of transaction). To avoid unclean deactivation (uninstall) of storage engine plugin in the middle of transaction, additional storage engine plugin lock is acquired by thd_set_ha_data(). If ha_data is not null and storage engine plugin was not locked by thd_set_ha_data() in this connection before, storage engine plugin gets locked. If ha_data is null and storage engine plugin was locked by thd_set_ha_data() in this connection before, storage engine plugin lock gets released. If handlerton::close_connection() didn't reset ha_data, server does it immediately after calling handlerton::close_connection(). Note that this is just a framework fix, storage engines must switch to thd_set_ha_data() from thd_ha_data() if they want to see fit. include/mysql/plugin.h: As thd_{get\|set}_ha_data() have some extra logic now, they must be implemented on server side. include/mysql/plugin.h.pp: As thd_{get\|set}_ha_data() have some extra logic now, they must be implemented on server side. sql/handler.cc: Make sure ha_data is reset and ha_data lock is released. sql/handler.h: hton is not supposed to be updated by ha_lock_engine(), make it const. sql/sql_class.cc: As thd_{get\|set}_ha_data() have some extra logic now, they must be implemented on server side. sql/sql_class.h: Added ha_data lock.	16 years ago

Sergey Petrunya	96e092dc73	Backport into MariaDB-5.2 the following: WL#2474 "Multi Range Read: Change the default MRR implementation to implement new MRR interface" WL#2475 "Batched range read functions for MyISAM/InnoDb" "Index condition pushdown for MyISAM/InnoDB" Igor's fix from sp1r-igor@olga.mysql.com-20080330055902-07614: There could be observed the following problems: 1. EXPLAIN did not mention pushdown conditions from on expressions in the 'extra' column. As a result if a query had no where conditions pushed down to a table, but had on conditions pushed to this table the 'extra' column in the EXPLAIN for the table missed 'using where'. 2. Conditions for ref access were not eliminated from on expressions though such conditions were eliminated from the where condition.	16 years ago
