Raghavendra D Prabhu	1077eef942	PXC-391: Avoid Total Order Isolation (TOI) for LOCAL sql admin commands. The admin commands in question are: > OPTIMIZE > REPAIR > ANALYZE For LOCAL or NO_WRITE_TO_BINLOG invocations of these commands, ie OPTIMIZE LOCAL TABLE <t1> they are not binlogged as expected. Also, in addition, they are not executed under TOI. Hence, they are not propagated to other nodes. The effect is same as that of wsrep_on=0. Also added tests for this. A WSREP_DEBUG for wsrep_register_hton has also been added. The galera_flush_local test has also been updated for verifying that effects of NO_WRITE_TO_BINLOG / LOCAL are equivalent to wsrep_on=0 from wsrep perspective.

Ajo Robert	15de3c6275	Bug#19817021 CRASH IN TABLE_LIST::PREPARE_SECURITY WHEN DOING BAD DDL IN PREPARED STATEMENT Analysis ======== A repeat execution of the prepared statement 'ALTER TABLE v1 CHECK PARTITION' where v1 is a view leads to server exit. ALTER TABLE ... CHECK PARTITION is not applicable for views and check for the same check is missing. This leads to further execution and creation of derived table for the view (Allocated under temp_table mem_root). Any reference to open view or related pointers from second execution leads to server exit as the same was freed at previous execution closure. Fix: ====== Added check for view in mysql_admin_table() on PARTITION operation. This will prevent mysql_admin_table() from going ahead and creating temp table and related issues. Changed message on admin table view operation error to be more appropriate.	10 years ago
Monty	3cb578c001	MDEV-6152: Remove calls to current_thd while creating Item - Part 3: Adding mem_root to push_back() and push_front() Other things: - Added THD as an argument to some partition functions. - Added memory overflow checking for XML tag's in read_xml()	10 years ago
Monty	1bae0d9e56	Stage 2 of MDEV-6152: - Added mem_root to all calls to new Item - Added private method operator new(size_t size) to Item to ensure that we always use a mem_root when creating an item. This saves use once call to current_thd per Item creation	10 years ago
Sergey Vojtovich	31e365efae	MDEV-8010 - Avoid sql_alloc() in Items (Patch #1 ) Added mandatory thd parameter to Item (and all derivative classes) constructor. Added thd parameter to all routines that may create items. Also removed "current_thd" from Item::Item. This reduced number of pthread_getspecific() calls from 290 to 177 per OLTP RO transaction.	10 years ago
Monty	7332af49e4	- Renaming variables so that they don't shadow others (After this patch one can compile with -Wshadow and get much fewer warnings) - Changed ER(ER_...) to ER_THD(thd, ER_...) when thd was known or if there was many calls to current_thd in the same function. - Changed ER(ER_..) to ER_THD_OR_DEFAULT(current_thd, ER...) in some places where current_thd is not necessary defined. - Removing calls to current_thd when we have access to thd Part of this is optimization (not calling current_thd when not needed), but part is bug fixing for error condition when current_thd is not defined (For example on startup and end of mysqld) Notable renames done as otherwise a lot of functions would have to be changed: - In JOIN structure renamed: examined_rows -> join_examined_rows record_count -> join_record_count - In Field, renamed new_field() to make_new_field() Other things: - Added DBUG_ASSERT(thd == tmp_thd) in Item_singlerow_subselect() just to be safe. - Removed old 'tab' prefix in JOIN_TAB::save_explain_data() and use members directly - Added 'thd' as argument to a few functions to avoid calling current_thd.	11 years ago

Kristian Nielsen	3b961347db	MDEV-7888, MDEV-7929: Parallel replication hangs sometimes on ANALYZE TABLE or DDL The hangs occur when the group_commit_orderer object is freed before the last mark_start_commit() call on it - this loses the wakeup to other waiting worker threads, causing them to hang until killed manually. The object was freed because wakeup_subsequent_commits() was called two early in two places. For MDEV-7888, during ANALYZE TABLE, and for MDEV-7929 during record_gtid() after processing a DDL event. The group_commit_orderer object can be freed when its last transaction has called wait_for_prior_commit(). Fix by implementing a suspend/resume mechanism for wakeup_subsequent_commits() that can be used in places where a transaction is committed without this being the commit of the actual replication event group. Also add a protection mechanism (that asserts in debug builds) which can prevent the too-early free and hang if other similar bugs should remain in other parts of the code.	11 years ago

Michael Widenius	70823e1d91	MDEV-5120 Test suite test maria-no-logging fails The reason for the failure was a bug in an include file on debian that causes 'struct stat' to have different sized depending on the environment. This patch fixes so that we always include my_global.h or my_config.h before we include any other files. Other things: - Removed #include <my_global.h> in some include files; Better to always do this at the top level to have as few "always-include-this-file-first' files as possible. - Removed usage of some include files that where already included by my_global.h or by other files. client/mysql_plugin.c: Use my_global.h first client/mysqlslap.c: Remove duplicated include files extra/comp_err.c:

unknown	629b822913	MDEV-5262, MDEV-5914, MDEV-5941, MDEV-6020: Deadlocks during parallel replication causing replication to fail. In parallel replication, we run transactions from the master in parallel, but force them to commit in the same order they did on the master. If we force T1 to commit before T2, but T2 holds eg. a row lock that is needed by T1, we get a deadlock when T2 waits until T1 has committed. Usually, we do not run T1 and T2 in parallel if there is a chance that they can have conflicting locks like this, but there are certain edge cases where it can occasionally happen (eg. MDEV-5914, MDEV-5941, MDEV-6020). The bug was that this would cause replication to hang, eventually getting a lock timeout and causing the slave to stop with error. With this patch, InnoDB will report back to the upper layer whenever a transactions T1 is about to do a lock wait on T2. If T1 and T2 are parallel replication transactions, and T2 needs to commit later than T1, we can thus detect the deadlock; we then kill T2, setting a flag that causes it to catch the kill and convert it to a deadlock error; this error will then cause T2 to roll back and release its locks (so that T1 can commit), and later T2 will be re-tried and eventually also committed. The kill happens asynchroneously in a slave background thread; this is necessary, as the reporting from InnoDB about lock waits happen deep inside the locking code, at a point where it is not possible to directly call THD::awake() due to mutexes held. Deadlock is assumed to be (very) rarely occuring, so this patch tries to minimise the performance impact on the normal case where no deadlocks occur, rather than optimise the handling of the occasional deadlock. Also fix transaction retry due to deadlock when it happens after a transaction already signalled to later transactions that it started to commit. In this case we need to undo this signalling (and later redo it when we commit again during retry), so following transactions will not start too early. Also add a missing thd->send_kill_message() that got triggered during testing (this corrects an incorrect fix for MySQL Bug#58933).	12 years ago

Dmitry Lenev	fc2c669297	Fix for bug#14188793 - "DEADLOCK CAUSED BY ALTER TABLE DOEN'T CLEAR STATUS OF ROLLBACKED TRANSACTION" and bug #17054007 - "TRANSACTION IS NOT FULLY ROLLED BACK IN CASE OF INNODB DEADLOCK". The problem in the first bug report was that although deadlock involving metadata locks was reported using the same error code and message as InnoDB deadlock it didn't rollback transaction like the latter. This caused confusion to users as in some cases after ER_LOCK_DEADLOCK transaction could have been restarted immediately and in some cases rollback was required. The problem in the second bug report was that although InnoDB deadlock caused transaction rollback in all storage engines it didn't cause release of metadata locks. So concurrent DDL on the tables used in transaction was blocked until implicit or explicit COMMIT or ROLLBACK was issued in the connection which got InnoDB deadlock. The former issue has stemmed from the fact that when support for detection and reporting metadata locks deadlocks was added we erroneously assumed that InnoDB doesn't rollback transaction on deadlock but only last statement (while this is what happens on InnoDB lock timeout actually) and so didn't implement rollback of transactions on MDL deadlocks. The latter issue was caused by the fact that rollback of transaction due to deadlock is carried out by setting THD::transaction_rollback_request flag at the point where deadlock is detected and performing rollback inside of trans_rollback_stmt() call when this flag is set. And trans_rollback_stmt() is not aware of MDL locks, so no MDL locks are released. This patch solves these two problems in the following way: - In case when MDL deadlock is detect transaction rollback is requested by setting THD::transaction_rollback_request flag. - Code performing rollback of transaction if THD::transaction_rollback_request is moved out from trans_rollback_stmt(). Now we handle rollback request on the same level as we call trans_rollback_stmt() and release statement/ transaction MDL locks.	12 years ago

And trans_rollback_stmt() is not aware of MDL locks, so no MDL locks are released. This patch solves these two problems in the following way: - In case when MDL deadlock is detect transaction rollback is requested by setting THD::transaction_rollback_request flag. - Code performing rollback of transaction if THD::transaction_rollback_request is moved out from trans_rollback_stmt(). Now we handle rollback request on the same level as we call trans_rollback_stmt() and release statement/ transaction MDL locks.	12 years ago
Sergey Vojtovich	b7f9c89423	MDEV-4702 - Reduce usage of LOCK_open Following variables do not require LOCK_open protection anymore: - table_def_cache (renamed to tdc_hash) is protected by rw-lock LOCK_tdc_hash; - table_def_shutdown_in_progress doesn't need LOCK_open protection; - last_table_id use atomics; - TABLE_SHARE::ref_count (renamed to TABLE_SHARE::tdc.ref_count) is protected by TABLE_SHARE::tdc.LOCK_table_share; - TABLE_SHARE::next, ::prev (renamed to tdc.next and tdc.prev), oldest_unused_share, end_of_unused_share are protected by LOCK_unused_shares; - TABLE_SHARE::m_flush_tickets (renamed to tdc.m_flush_tickets) is protected by TABLE_SHARE::tdc.LOCK_table_share; - refresh_version (renamed to tdc_version) use atomics.	12 years ago

Sergey Petrunya	56a6e71f9c	Fix merge.test failure - Problem: mysql_admin_table() calls open_temporary_tables(). This causes assertion failure, because mysql_execute_command() has already called open_temporary_tables() - Solution: call close_thread_tables() at the start of mysql_admin_table(), like mysql-5.6 does	13 years ago

Michael Widenius	8ed283d882	Fixed bug MPDEV-628 / LP:989055 - Querying myisam table metadata may corrupt the table. The issue was that there was that SHOW commands could open the table in the store engine, even in cases where it should not be allowed to do that (ie, the storage engines meta data for that table was under big changes). The cases where this should not be allowed are: - ALTER TABLE DISABLE KEYS - ALTER TABLE ENABLE KEYS - REPAIR TABLE - OPTIMIZE TABLE - DROP TABLE This patch adds a new mode, protected_against_usage(). If this is used then the SHOW command will wait until the table is accessable. This is implemented by re-using the already exising 'version' flag for TABLE_SHARE. It also added functions to be used to change TABLE_SHARE->version instead of changing it directly. mysql-test/r/myisam-metadata.result: Added test case mysql-test/t/myisam-metadata.test: Added test case sql/mysqld.cc: Start from refresh_version 2 as 0 and 1 are reserved. sql/sql_admin.cc: Added MYSQL_OPEN_FOR_REPAIR Updated call to wait_while_table_is_used() sql/sql_base.cc: Updated call to wait_while_table_is_used() - Allow one to specify how the table should be removed (for all commands except show or for all commands). - Don't allow one to reopen the table if one has called share->protect_against_usage() sql/sql_base.h: Added TDC_RT_REMOVE_NOT_OWN_AND_MARK_NOT_USABLE, which is used to mark that no one can reopen this table, except with MYSQL_OPEN_FOR_REPAIR . - Added MYSQL_OPEN_FOR_REPAIR - Updated prototype for wait_while_table_is_used() sql/sql_table.cc: Updated call to wait_while_table_is_used() Use MYSQL_OPEN_FOR_REPAIR for open tables that where repaired. sql/sql_truncate.cc: Updated call to wait_while_table_is_used() sql/table.cc: Use set_refresh_version() sql/table.h: Added functions to be used to change TABLE_SHARE->version instead of changing it directly	13 years ago
Sergei Golubchik	5205188200	cleanup: * remove unused mysql_option * don't allocate 5GB of memory in the mtr tests * restore the behavior in dynamic_column_offset_byte(), put the ifdef correctly * prefer __attribute__((unused)) to #ifdef * prefer UNINIT_VAR to LINT_INIT * make most Warning_info users blissfully unaware of the postponed initialization * use my_offsetof instead of offsetof where the compiler thinks the latter is incorrect	13 years ago
