Nirbhay Choubey	7305be2f7e	MDEV-5535: Cannot reopen temporary table mysqld maintains a list of TABLE objects for all temporary tables created within a session in THD. Here each table is represented by a TABLE object. A query referencing a particular temporary table for more than once, however, failed with ER_CANT_REOPEN_TABLE error because a TABLE_SHARE was allocate together with the TABLE, so temporary tables always had only one TABLE per TABLE_SHARE. This patch lift this restriction by separating TABLE and TABLE_SHARE objects and storing TABLE_SHAREs for temporary tables in a list in THD, and TABLEs in a list within their respective TABLE_SHAREs.	10 years ago

Nirbhay Choubey	78d4276788	Some trivial changes.	10 years ago
Sergey Vojtovich	7ecb304996	Code cleanups - unused TABLE_SHARE::deleting and TABLE_LIST::deleting flags were removed - kill_delayed_threads_for_table() and intern_close_table() are now private methods of table cache - removed free_share flag of closefrm(): it was never used for temporary tables and was rarely useful for regular tables	10 years ago

Sergey Vojtovich	9de6708390	MDEV-9857 - CACHE_LINE_SIZE in innodb should be 128 on POWER Replaced hard-coded cache line size. Changes based on Daniel Black's work.	10 years ago
Alexey Kopytov	49ad084503	Few improvements related to CPU cache line size and padding: Bug #79636: CACHE_LINE_SIZE should be 128 on AArch64 Bug #79637: Hard-coded cache line size Bug #79638: Reconcile CACHE_LINE_SIZE with CPU_LEVEL1_DCACHE_LINESIZE Bug #79652: Suspicious padding in srv_conc_t - changed CPU_LEVEL1_DCACHE_LINESIZE to default to 128 bytes on POWER and AArch64 architectures in cases when no value could be detected by CMake using getconf - changed CACHE_LINE_SIZE definition in ut0counter.h to be an alias of CPU_LEVEL1_DCACHE_LINESIZE - changed a number of hard-coded 64-byte cache line size values in the InnoDB code - fixed insufficient padding for srv_conc members in srv0conc.cc Ported to Mariadb by Daniel Black <daniel.black@au.ibm.com> Added s390 cache size of 256 at same time.	10 years ago

Sergei Golubchik	562c1df7d9	cleanup: thread_count move thread_count handling into THD: * increment thread_count in THD constructor * decrement thread_count in THD destructor * never modify thread_count directly!	10 years ago
Sergei Golubchik	7425610c81	decrement thead_count after THD is destroyed because thread_count means just that: number of THDs and shutdown code looks at it to know when to free shared data structures that THD uses. This fixes random crashes in ~THD on shutdown	10 years ago

Sergei Golubchik	69da361ccd	reset @@TIMESTAMP for COM_CHANGE_USER this also fixes tokudb.type_year failure (in ./mtr tokudb.type_timestamp tokudb.type_year)	10 years ago
Sergei Golubchik	4aacb20dce	fix XID comparison according to the standard, the gtrid/bqual pair must be "globally unique", so XIDs are equal if their gtrids and bquals are identical, formatID simply tells how gtrid/bqual were generated. But if formatID == -1 (it means "null") gtrid/bqual don't have any value at all. This fixes main.xa_sync failure in ./mtr main.quary_cache_debug main.xa_sync	10 years ago
Monty	89685d55d7	Reuse THD for new user connections - To ensure that mallocs are marked for the correct THD, even if it's allocated in another thread, I added the thread_id to the THD constructor - Added st_my_thread_var to thr_lock_info_init() to avoid a call to my_thread_var - Moved things from THD::THD() to THD::init() - Moved some things to THD::cleanup() - Added THD::free_connection() and THD::reset_for_reuse() - Added THD to CONNECT::create_thd() - Added THD::thread_dbug_id and st_my_thread_var->dbug_id. These are needed to ensure that we have a constant thread_id used for debugging with a THD, even if it changes thread_id (=connection_id) - Set variables.pseudo_thread_id in constructor. Removed not needed sets.	10 years ago

Sergey Vojtovich	d6d4011211	Move wait_for_mdl_deadlock_detector() call to tc_remove_table() As a side effect tc_remove_all_unused_tables() has to call tc_wait_for_mdl_deadlock_detector() once per TABLE object now, while it called it only once before. This should be acceptable since actual wait will still be performed only once. It only adds redundant checks for all_tables_refs.	10 years ago

Alexander Barkov	286416404a	MDEV-10101 Wrong error message of SELECT 1 UNION (SELECT 1 FROM t1 GROUP BY 1 WITH ROLLUP)	10 years ago
Alexander Barkov	caee832df1	MDEV-10124 Incorrect usage of CUBE/ROLLUP and ORDER BY with GROUP_CONCAT(a ORDER BY a) Allowing GROUP_CONCAT(... ORDER BY ..) in queries with ROLLUP. The story of the related code: 1. The original patch from Wax commit: `0b505fb437` date: Tue Mar 18 03:07:40 2003 opt_gorder_clause reused the regular order_clause, which already had some protection against ROLLUP queries: order_clause: ORDER_SYM BY { LEX *lex=Lex; if (lex->current_select->linkage != GLOBAL_OPTIONS_TYPE && lex->current_select->select_lex()->olap != UNSPECIFIED_OLAP_TYPE) { net_printf(lex->thd, ER_WRONG_USAGE, "CUBE/ROLLUP", "ORDER BY"); YYABORT; } } order_list; The assumption that ORDER BY in group_concat() had to have the same ROLLUP restriction (with order_clause) was wrong. Moreover, GROUP_CONCAT() in select_item_list was not affected by this restriction, because WITH ROLLUP goes after select_item_list and therefore sel->olap is always equal to UNSPECIFIED_OLAP_TYPE during select_item_list. GROUP BY was not affected for two reasons: - it goes before WITH ROLLUP and sel->olap is still UNSPECIFIED_OLAP_TYPE - Aggregate functions like AVG(), GROUP_CONCAT() in GROUP BY are not allowed So only GROUP_CONCAT() in HAVING and ORDER BY clauses were erroneously affected by this restriction. 2. Bug#27848 rollup in union part causes error with order of union commit: `3f6073ae63` Author: unknown <igor@olga.mysql.com> 2007-12-15 01:42:46 The condition in the ROLLUP protection code became more complex. Note, opt_gconcat_order still reused the regular order_clause. 3. Bug#16347426 ASSERTION FAILED: (SELECT_INSERT && !TABLES->NEXT_NAME_RESOLUTION_TABLE) \|\| !TAB commit: `2d83663380` author: Chaithra Gopalareddy <chaithra.gopalareddy@oracle.com> date: 2013-04-14 06:00:49 opt_gorder_clause was refactored not to use order_clause and to collect information directly to select->gorder_list. The ROLLUP protection code was duplicated from order_clause to the new version of opt_gorder_clause.	10 years ago
Nirbhay Choubey	de7eafc7ce	MDEV-6368: assertion xid_seqno > trx_sys_cur_xid_seqno - Validate the specified wsrep_start_position value by also checking the return status of wsrep->sst_received. This also ensures that changes in wsrep_start_position is not allowed when the node is not in JOINING state. - Do not allow decrease in seqno within same UUID. - The initial checkpoint in SEs should be [0...:-1].	10 years ago

Alexander Barkov	804b00e878	An sql_yacc.yy clean-up - Moving opt_union_order_or_limit inside union_opt, as it's not used in other places any more. - Changing union_opt to have no type. Earlier (before all MDEV-8909 dependency tasks) it had the <num> type, and it's return value was used to generate errors. Now union_opt does not need a return value because the grammar disallows ORDER and LIMIT clauses in wrong context.	10 years ago

Alexander Barkov	349da1d643	sql_yacc.yy: Removing unnecessary init_nested_join() and end_nested_join() from select_derived_init.	10 years ago
Alexander Barkov	c44b2e66a9	A derived_query_specification clean-up (to simplify further MDEV-8909 changes) 1. Better semantic readability: - Moving get_select_lex_derived inside select_derived_init and decomposing it into get_select_lex and $1->init_nested_join(lex->thd) - Moving DBUG_ASSERT($1 == Lex->current_select) inside select_derived_init Now init_nested_join() and end_nested_join() reside inside the same rule select_derived_init. (It's very likely that they can be further removed, as there are no any joins in this rule). 3. Better grammar readability: Moving SELECT_SYM from select_derived_init to derived_query_specification. It's easier to read a rule when it starts from a terminal symbol.	10 years ago
Oleksandr Byelkin	485ece6da9	MDEV-8429: Change binlog_checksum default to match MySQL 5.6.6+	10 years ago
Alexander Barkov	f6a7c1c75a	MDEV-10080 Derived tables allow double LIMIT clause 1. Moving the "\| get_select_lex_derived select_derived_init" part of select_derived into a separate new rule derived_query_specification. 2. Using derived_query_specification directly in select_derived_union rather than in select_derived. 3. Moving the sequence "opt_order_clause opt_limit_clause opt_select_lock_type" from select_derived2 to select_derived_union, after derived_query_specification. Effectively, the parser now does not go through the sequence "opt_order_clause opt_limit_clause ... opt_union_order_or_limit" any more. This fixes the problem with double LIMIT clause and removes 2 shift/reduce conflicts.	10 years ago
Alexander Barkov	c9629daa1e	This patch is a cleanup simplifying upcoming "MDEV-8909 union parser cleanup" changes. When the server parses a query like SELECT * FROM (SELECT 1); a sequence of calls st_select_lex::init_nested_join() .. st_select_lex::end_nested_join() was performed two times (tested in gdb). Both pairs of calls seem to be redundant for a query like this, because there are actually no any joins here. This patch moved "table_ref_select" inside "select_derived", which revealed that one the pairs was definitely redundant: After this transformation we got an init_nested_join() immediately followed by end_nested_join() for the same st_select_lex, which has no any sense. So this pair of calls was removed.	10 years ago
