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

Jon Olav Hauglid	0db0e64f33	Bug #11755431 (former 47205) MAP 'REPAIR TABLE' TO RECREATE +ANALYZE FOR ENGINES NOT SUPPORTING NATIVE REPAIR Executing 'mysqlcheck --check-upgrade --auto-repair ...' will first issue 'CHECK TABLE FOR UPGRADE' for all tables in the database in order to check if the tables are compatible with the current version of MySQL. Any tables that are found incompatible are then upgraded using 'REPAIR TABLE'. The problem was that some engines (e.g. InnoDB) do not support 'REPAIR TABLE'. This caused any such tables to be left incompatible. As a result such tables were not properly fixed by the mysql_upgrade tool. This patch fixes the problem by first changing 'CHECK TABLE FOR UPGRADE' to return a different error message if the engine does not support REPAIR. Instead of "Table upgrade required. Please do "REPAIR TABLE ..." it will report "Table rebuild required. Please do "ALTER TABLE ... FORCE ..." Second, the patch changes mysqlcheck to do 'ALTER TABLE ... FORCE' instead of 'REPAIR TABLE' in these cases. This patch also fixes 'ALTER TABLE ... FORCE' to actually rebuild the table. This change should be reflected in the documentation. Before this patch, 'ALTER TABLE ... FORCE' was unused (See Bug#11746162) Test case added to mysqlcheck.test client/mysqlcheck.c: Changed mysqlcheck to do 'ALTER TABLE ... FORCE' if 'CHECK TABLE FOR UPGRADE' reports ER_TABLE_NEEDS_REBUILD and not ER_TABLE_NEEDS_UPGRADE. mysql-test/r/mysqlcheck.result: Added regression test. mysql-test/std_data/bug47205.frm: InnoDB 5.0 FRM which contains a varchar primary key using utf8_general_ci. This is an incompatible FRM for 5.5. mysql-test/t/mysqlcheck.test: Added regression test. sql/handler.h: Added new HA_CAN_REPAIR flag. sql/share/errmsg-utf8.txt: Added new error message ER_TABLE_NEEDS_REBUILD sql/sql_admin.cc: Changed 'CHECK TABLE FOR UPDATE' to give ER_TABLE_NEEDS_REBUILD instead of ER_TABLE_NEEDS_UPGRADE if the engine does not support REPAIR (as indicated by the new HA_CAN_REPAIR flag). sql/sql_lex.h: Remove unused ALTER_FORCE flag. sql/sql_yacc.yy: Make sure ALTER TABLE ... FORCE recreates the table by setting the ALTER_RECREATE flag as the ALTER_FORCE flag was unused. storage/archive/ha_archive.h: Added new HA_CAN_REPAIR flag to Archive storage/csv/ha_tina.h: Added new HA_CAN_REPAIR flag to CSV storage/federated/ha_federated.h: Added new HA_CAN_REPAIR flag to Federated storage/myisam/ha_myisam.cc: Added new HA_CAN_REPAIR flag to MyISAM	15 years ago
Magnus Blåudd	0be575b7c8	Bug#60111 storage type for table not saved in .frm - Add new "format section" in extra data segment with additional table and column properties. This was originally introduced in 5.1.20 based MySQL Cluster - Remove hardcoded STORAGE DISK for table and instead output the real storage format used. Keep both TABLESPACE and STORAGE inside same version guard. - Implement default version of handler::get_tablespace_name() since tablespace is now available in share and it's unnecessary for each handler to implement. (the function could actually be removed totally now). - Add test for combinations of TABLESPACE and STORAGE with CREATE TABLE and ALTER TABLE - Add test to show that 5.5 now can read a .frm file created by MySQL Cluster 7.0.22. Although it does not yet show the column level attributes, they are read.	15 years ago
Jon Olav Hauglid	e99f2b1c4e	Bug #42230 during add index, cannot do queries on storage engines that implement add_index The problem was that ALTER TABLE blocked reads on an InnoDB table while adding a secondary index, even if this was not needed. It is only needed for the final step where the .frm file is updated. The reason queries were blocked, was that ALTER TABLE upgraded the metadata lock from MDL_SHARED_NO_WRITE (which blocks writes) to MDL_EXCLUSIVE (which blocks all accesses) before index creation. The way the server handles index creation, is that storage engines publish their capabilities to the server and the server determines which of the following three ways this can be handled: 1) build a new version of the table; 2) change the existing table but with exclusive metadata lock; 3) change the existing table but without metadata lock upgrade. For InnoDB and secondary index creation, option 3) should have been selected. However this failed for two reasons. First, InnoDB did not publish this capability properly. Second, the ALTER TABLE code failed to made proper use of the information supplied by the storage engine. A variable need_lock_for_indexes was set accordingly, but was not later used. This patch fixes this problem by only doing metadata lock upgrade before index creation/deletion if this variable has been set. This patch also changes some of the related terminology used in the code. Specifically the use of "fast" and "online" with respect to ALTER TABLE. "Fast" was used to indicate that an ALTER TABLE operation could be done without involving a temporary table. "Fast" has been renamed "in-place" to more accurately describe the behavior. "Online" meant that the operation could be done without taking a table lock. However, in the current implementation writes are always prohibited during ALTER TABLE and an exclusive metadata lock is held while updating the .frm, so ALTER TABLE is not completely online. This patch replaces "online" with "in-place", with additional comments indicating if concurrent reads are allowed during index creation/deletion or not. An important part of this update of terminology is renaming of the handler flags used by handlers to indicate if index creation/deletion can be done in-place and if concurrent reads are allowed. For example, the HA_ONLINE_ADD_INDEX_NO_WRITES flag has been renamed to HA_INPLACE_ADD_INDEX_NO_READ_WRITE, while HA_ONLINE_ADD_INDEX is now HA_INPLACE_ADD_INDEX_NO_WRITE. Note that this is a rename to clarify current behavior, the flag values have not changed and no flags have been removed or added. Test case added to innodb_mysql_sync.test.	15 years ago
Mattias Jonsson	c04318ed24	Bug#57778: failed primary key add to partitioned innodb table inconsistent and crashes It was possible to issue an ALTER TABLE ADD PRIMARY KEY on an partitioned InnoDB table that failed and crashed the server. The problem was that it succeeded to create the PK on at least one partition, and then failed on a subsequent partition, due to duplicate key violation. Since the partitions that already had added the PK was not reverted all partitions was not consistent with the table definition, which caused the crash. The solution was to add a revert step to ha_partition::add_index() that dropped the index for the already succeeded partitions, on failure. mysql-test/r/partition.result: updated result mysql-test/t/partition.test: Added test sql/ha_partition.cc: Only allow ADD/DROP flags in pairs, so that they can be reverted on failures. If add_index() fails for a partition, revert (drop the index) for the previous partitions. sql/handler.h: Added some extra info in a comment.	15 years ago
Davi Arnaut	a5efb91dea	Bug#49938: Failing assertion: inode or deadlock in fsp/fsp0fsp.c Bug#54678: InnoDB, TRUNCATE, ALTER, I_S SELECT, crash or deadlock - Incompatible change: truncate no longer resorts to a row by row delete if the storage engine does not support the truncate method. Consequently, the count of affected rows does not, in any case, reflect the actual number of rows. - Incompatible change: it is no longer possible to truncate a table that participates as a parent in a foreign key constraint, unless it is a self-referencing constraint (both parent and child are in the same table). To work around this incompatible change and still be able to truncate such tables, disable foreign checks with SET foreign_key_checks=0 before truncate. Alternatively, if foreign key checks are necessary, please use a DELETE statement without a WHERE condition. Problem description: The problem was that for storage engines that do not support truncate table via a external drop and recreate, such as InnoDB which implements truncate via a internal drop and recreate, the delete_all_rows method could be invoked with a shared metadata lock, causing problems if the engine needed exclusive access to some internal metadata. This problem originated with the fact that there is no truncate specific handler method, which ended up leading to a abuse of the delete_all_rows method that is primarily used for delete operations without a condition. Solution: The solution is to introduce a truncate handler method that is invoked when the engine does not support truncation via a table drop and recreate. This method is invoked under a exclusive metadata lock, so that there is only a single instance of the table when the method is invoked. Also, the method is not invoked and a error is thrown if the table is a parent in a non-self-referencing foreign key relationship. This was necessary to avoid inconsistency as some integrity checks are bypassed. This is inline with the fact that truncate is primarily a DDL operation that was designed to quickly remove all data from a table. mysql-test/suite/innodb/t/innodb-truncate.test: Add test cases for truncate and foreign key checks. Also test that InnoDB resets auto-increment on truncate. mysql-test/suite/innodb/t/innodb.test: FK is not necessary, test is related to auto-increment. Update error number, truncate is no longer invoked if table is parent in a FK relationship. mysql-test/suite/innodb/t/innodb_mysql.test: Update error number, truncate is no longer invoked if table is parent in a FK relationship. Use delete instead of truncate, test is used to check the interaction of FKs, triggers and delete. mysql-test/suite/parts/inc/partition_check.inc: Fix typo. mysql-test/suite/sys_vars/t/foreign_key_checks_func.test: Update error number, truncate is no longer invoked if table is parent in a FK relationship. mysql-test/t/mdl_sync.test: Modify test case to reflect and ensure that truncate takes a exclusive metadata lock. mysql-test/t/trigger-trans.test: Update error number, truncate is no longer invoked if table is parent in a FK relationship. sql/ha_partition.cc: Reorganize the various truncate methods. delete_all_rows is now passed directly to the underlying engines, so as truncate. The code responsible for truncating individual partitions is moved to ha_partition::truncate_partition, which is invoked when a ALTER TABLE t1 TRUNCATE PARTITION p statement is executed. Since the partition truncate no longer can be invoked via delete, the bitmap operations are not necessary anymore. The explicit reset of the auto-increment value is also removed as the underlying engines are now responsible for reseting the value. sql/handler.cc: Wire up the handler truncate method. sql/handler.h: Introduce and document the truncate handler method. It assumes certain use cases of delete_all_rows. Add method to retrieve the list of foreign keys referencing a table. Method is used to avoid truncating tables that are parent in a foreign key relationship. sql/share/errmsg-utf8.txt: Add error message for truncate and FK. sql/sql_lex.h: Introduce a flag so that the partition engine can detect when a partition is being truncated. Used to give a special error. sql/sql_parse.cc: Function mysql_truncate_table no longer exists. sql/sql_partition_admin.cc: Implement the TRUNCATE PARTITION statement. sql/sql_truncate.cc: Change the truncate table implementation to use the new truncate handler method and to not rely on row-by-row delete anymore. The truncate handler method is always invoked with a exclusive metadata lock. Also, it is no longer possible to truncate a table that is parent in some non-self-referencing foreign key. storage/archive/ha_archive.cc: Rename method as the description indicates that in the future this could be a truncate operation. storage/blackhole/ha_blackhole.cc: Implement truncate as no operation for the blackhole engine in order to remain compatible with older releases. storage/federated/ha_federated.cc: Introduce truncate method that invokes delete_all_rows. This is required to support partition truncate as this form of truncate does not implement the drop and recreate protocol. storage/heap/ha_heap.cc: Introduce truncate method that invokes delete_all_rows. This is required to support partition truncate as this form of truncate does not implement the drop and recreate protocol. storage/ibmdb2i/ha_ibmdb2i.cc: Introduce truncate method that invokes delete_all_rows. This is required to support partition truncate as this form of truncate does not implement the drop and recreate protocol. storage/innobase/handler/ha_innodb.cc: Rename delete_all_rows to truncate. InnoDB now does truncate under a exclusive metadata lock. Introduce and reorganize methods used to retrieve the list of foreign keys referenced by a or referencing a table. storage/myisammrg/ha_myisammrg.cc: Introduce truncate method that invokes delete_all_rows. This is required in order to remain compatible with earlier releases where truncate would resort to a row-by-row delete.	15 years ago
unknown	d0d8bbed5e	WL#5370 Keep forward-compatibility when changing 'CREATE TABLE IF NOT EXISTS ... SELECT' behaviour BUG#47132, BUG#47442, BUG49494, BUG#23992 and BUG#48814 will disappear automatically after the this patch. BUG#55617 is fixed by this patch too. This is the 5.5 part. It implements: - 'CREATE TABLE IF NOT EXISTS ... SELECT' statement will not insert anything and binlog anything if the table already exists. It only generate a warning that table already exists. - A couple of test cases for the behavior changing.	15 years ago
Konstantin Osipov	523066987d	A fix for Bug#41158 "DROP TABLE holds LOCK_open during unlink()". Remove acquisition of LOCK_open around file system operations, since such operations are now protected by metadata locks. Rework table discovery algorithm to not require LOCK_open. No new tests added since all MDL locking operations are covered in lock.test and mdl_sync.test, and as long as these tests pass despite the increased concurrency, consistency must be unaffected. mysql-test/t/disabled.def: Disable NDB tests due to Bug#55799. sql/datadict.cc: No longer necessary to protect ha_create_table() with LOCK_open. Serial execution is now ensured by metadata locks. sql/ha_ndbcluster.cc: Do not manipulate with LOCK_open in cluster code. sql/ha_ndbcluster_binlog.cc: Do not manipulate with LOCK_open in cluster code. sql/ha_ndbcluster_binlog.h: Update function signature. sql/handler.cc: Implement ha_check_if_table_exists(). @todo: some engines provide ha_table_exists_in_engine() handlerton call, for those we perhaps shouldn't call ha_discover(), to be more efficient. Since currently it's only NDB, postpone till integration with NDB. sql/handler.h: Declare ha_check_if_table_exists() function. sql/mdl.cc: Remove an obsolete comment. sql/sql_base.cc: Update to a new signature of close_cached_tables(): from now on we always call it without LOCK_open. Update comments. Remove get_table_share_with_create(), we should not attempt to create a table under LOCK_open. Introduce get_table_share_with_discover() instead, which would request a back off action if the table exists in engine. Remove acquisition of LOCK_open for data dictionary operations, such as check_if_table_exists(). Do not use get_table_share_with_create/discover for views, where it's not needed. Make tdc_remove_table() optionally acquire LOCK_open to simplify usage of this function. Use the right mutex in the partitioning code when manipulating with thd->open_tables. sql/sql_base.h: Update signatures of changes functions. sql/sql_insert.cc: Do not wrap quick_rm_table() with LOCK_open acquisition, this is unnecessary. sql/sql_parse.cc: Update to the new calling convention of tdc_remove_table(). Update to the new signature of close_cached_tables(). Update comments. sql/sql_rename.cc: Update to the new calling convention of tdc_remove_table(). Remove acquisition of LOCK_open around filesystem operations. sql/sql_show.cc: Remove get_trigger_table_impl(). Do not acquire LOCK_open for a dirty read of the trigger file. sql/sql_table.cc: Do not acquire LOCK_open for filesystem operations. sql/sql_trigger.cc: Do not require LOCK_open for trigger file I/O. sql/sql_truncate.cc: Update to the new signature of tdc_remove_table(). sql/sql_view.cc: Do not require LOCK_open for view I/O. Use tdc_remove_table() to expel view share. Update comments. sql/sys_vars.cc: Update to the new signature of close_cached_tables().	15 years ago
Konstantin Osipov	36290c0923	A pre-requisite patch for the fix for Bug#52044. This patch also fixes Bug#55452 "SET PASSWORD is replicated twice in RBR mode". The goal of this patch is to remove the release of metadata locks from close_thread_tables(). This is necessary to not mistakenly release the locks in the course of a multi-step operation that involves multiple close_thread_tables() or close_tables_for_reopen(). On the same token, move statement commit outside close_thread_tables(). Other cleanups: Cleanup COM_FIELD_LIST. Don't call close_thread_tables() in COM_SHUTDOWN -- there are no open tables there that can be closed (we leave the locked tables mode in THD destructor, and this close_thread_tables() won't leave it anyway). Make open_and_lock_tables() and open_and_lock_tables_derived() call close_thread_tables() upon failure. Remove the calls to close_thread_tables() that are now unnecessary. Simplify the back off condition in Open_table_context. Streamline metadata lock handling in LOCK TABLES implementation. Add asserts to ensure correct life cycle of statement transaction in a session. Remove a piece of dead code that has also become redundant after the fix for Bug 37521. mysql-test/r/variables.result: Update results: set @@autocommit and statement transaction/ prelocked mode. mysql-test/r/view.result: A harmless change in CHECK TABLE <view> status for a broken view. If previously a failure to prelock all functions used in a view would leave the connection in LTM_PRELOCKED mode, now we call close_thread_tables() from open_and_lock_tables() and leave prelocked mode, thus some check in mysql_admin_table() that works only in prelocked/locked tables mode is no longer activated. mysql-test/suite/rpl/r/rpl_row_implicit_commit_binlog.result: Fixed Bug#55452 "SET PASSWORD is replicated twice in RBR mode": extra binlog events are gone from the binary log. mysql-test/t/variables.test: Add a test case: set autocommit and statement transaction/prelocked mode. sql/event_data_objects.cc: Simplify code in Event_job_data::execute(). Move sp_head memory management to lex_end(). sql/event_db_repository.cc: Move the release of metadata locks outside close_thread_tables(). Make sure we call close_thread_tables() when open_and_lock_tables() fails and remove extra code from the events data dictionary. Use close_mysql_tables(), a new internal function to properly close mysql.* tables in the data dictionary. Contract Event_db_repository::drop_events_by_field, drop_schema_events into one function. When dropping all events in a schema, make sure we don't mistakenly release all locks acquired by DROP DATABASE. These include locks on the database name and the global intention exclusive metadata lock. sql/event_db_repository.h: Function open_event_table() does not require an instance of Event_db_repository. sql/events.cc: Use close_mysql_tables() instead of close_thread_tables() to bootstrap events, since the latter no longer releases metadata locks. sql/ha_ndbcluster.cc: - mysql_rm_table_part2 no longer releases acquired metadata locks. Do it in the caller. sql/ha_ndbcluster_binlog.cc: Deploy the new protocol for closing thread tables in run_query() and ndb_binlog_index code. sql/handler.cc: Assert that we never call ha_commit_trans/ ha_rollback_trans in sub-statement, which is now the case. sql/handler.h: Add an accessor to check whether THD_TRANS object is empty (has no transaction started). sql/log.cc: Update a comment. sql/log_event.cc: Since now we commit/rollback statement transaction in mysql_execute_command(), we need a mechanism to communicate from Query_log_event::do_apply_event() to mysql_execute_command() that the statement transaction should be rolled back, not committed. Ideally it would be a virtual method of THD. I hesitate to make THD a virtual base class in this already large patch. Use a thd->variables.option_bits for now. Remove a call to close_thread_tables() from the slave IO thread. It doesn't open any tables, and the protocol for closing thread tables is more complicated now. Make sure we properly close thread tables, however, in Load_data_log_event, which doesn't follow the standard server execution procedure with mysql_execute_command(). @todo: this piece should use Server_runnable framework instead. Remove an unnecessary call to mysql_unlock_tables(). sql/rpl_rli.cc: Update Relay_log_info::slave_close_thread_tables() to follow the new close protocol. sql/set_var.cc: Remove an unused header. sql/slave.cc: Remove an unnecessary call to close_thread_tables(). sql/sp.cc: Remove unnecessary calls to close_thread_tables() from SP DDL implementation. The tables will be closed by the caller, in mysql_execute_command(). When dropping all routines in a database, make sure to not mistakenly drop all metadata locks acquired so far, they include the scoped lock on the schema. sql/sp_head.cc: Correct the protocol that closes thread tables in an SP instruction. Clear lex->sphead before cleaning up lex with lex_end to make sure that we don't delete the sphead twice. It's considered to be "cleaner" and more in line with future changes than calling delete lex->sphead in other places that cleanup the lex. sql/sp_head.h: When destroying m_lex_keeper of an instruction, don't delete the sphead that all lex objects share. @todo: don't store a reference to routine's sp_head instance in instruction's lex. sql/sql_acl.cc: Don't call close_thread_tables() where the caller will do that for us. Fix Bug#55452 "SET PASSWORD is replicated twice in RBR mode" by disabling RBR replication in change_password() function. Use close_mysql_tables() in bootstrap and ACL reload code to make sure we release all metadata locks. sql/sql_base.cc: This is the main part of the patch: - remove manipulation with thd->transaction and thd->mdl_context from close_thread_tables(). Now this function is only responsible for closing tables, nothing else. This is necessary to be able to easily use close_thread_tables() in procedures, that involve multiple open/close tables, which all need to be protected continuously by metadata locks. Add asserts ensuring that TABLE object is only used when is protected by a metadata lock. Simplify the back off condition of Open_table_context, we no longer need to look at the autocommit mode. Make open_and_lock_tables() and open_normal_and_derived_tables() close thread tables and release metadata locks acquired so-far upon failure. This simplifies their usage. Implement close_mysql_tables(). sql/sql_base.h: Add declaration for close_mysql_tables(). sql/sql_class.cc: Remove a piece of dead code that has also become redundant after the fix for Bug 37521. The code became dead when my_eof() was made a non-protocol method, but a method that merely modifies the diagnostics area. The code became redundant with the fix for Bug#37521, when we started to cal close_thread_tables() before Protocol::end_statement(). sql/sql_do.cc: Do nothing in DO if inside a substatement (the assert moved out of trans_rollback_stmt). sql/sql_handler.cc: Add comments. sql/sql_insert.cc: Remove dead code. Release metadata locks explicitly at the end of the delayed insert thread. sql/sql_lex.cc: Add destruction of lex->sphead to lex_end(), lex "reset" method called at the end of each statement. sql/sql_parse.cc: Move close_thread_tables() and other related cleanups to mysql_execute_command() from dispatch_command(). This has become possible after the fix for Bug#37521. Mark federated SERVER statements as DDL. Next step: make sure that we don't store eof packet in the query cache, and move the query cache code outside mysql_parse. Brush up the code of COM_FIELD_LIST. Remove unnecessary calls to close_thread_tables(). When killing a query, don't report "OK" if it was a suicide. sql/sql_parse.h: Remove declaration of a function that is now static. sql/sql_partition.cc: Remove an unnecessary call to close_thread_tables(). sql/sql_plugin.cc: open_and_lock_tables() will clean up after itself after a failure. Move close_thread_tables() above end: label, and replace with close_mysql_tables(), which will also release the metadata lock on mysql.plugin. sql/sql_prepare.cc: Now that we no longer release locks in close_thread_tables() statement prepare code has become more straightforward. Remove the now redundant check for thd->killed() (used only by the backup project) from Execute_server_runnable. Reorder code to take into account that now mysql_execute_command() performs lex->unit.cleanup() and close_thread_tables(). sql/sql_priv.h: Add a new option to server options to interact between the slave SQL thread and execution framework (hack). @todo: use a virtual method of class THD instead. sql/sql_servers.cc: Due to Bug 25705 replication of DROP/CREATE/ALTER SERVER is broken. Make sure at least we do not attempt to replicate these statements using RBR, as this violates the assert in close_mysql_tables(). sql/sql_table.cc: Do not release metadata locks in mysql_rm_table_part2, this is done by the caller. Do not call close_thread_tables() in mysql_create_table(), this is done by the caller. Fix a bug in DROP TABLE under LOCK TABLES when, upon error in wait_while_table_is_used() we would mistakenly release the metadata lock on a non-dropped table. Explicitly release metadata locks when doing an implicit commit. sql/sql_trigger.cc: Now that we delete lex->sphead in lex_end(), zero the trigger's sphead in lex after loading the trigger, to avoid double deletion. sql/sql_udf.cc: Use close_mysql_tables() instead of close_thread_tables(). sql/sys_vars.cc: Remove code added in scope of WL#4284 which would break when we perform set @@session.autocommit along with setting other variables and using tables or functions. A test case added to variables.test. sql/transaction.cc: Add asserts. sql/tztime.cc: Use close_mysql_tables() rather than close_thread_tables().	16 years ago

Davi Arnaut	f56dd32bf7	Bug#34043: Server loops excessively in _checkchunk() when safemalloc is enabled Essentially, the problem is that safemalloc is excruciatingly slow as it checks all allocated blocks for overrun at each memory management primitive, yielding a almost exponential slowdown for the memory management functions (malloc, realloc, free). The overrun check basically consists of verifying some bytes of a block for certain magic keys, which catches some simple forms of overrun. Another minor problem is violation of aliasing rules and that its own internal list of blocks is prone to corruption. Another issue with safemalloc is rather the maintenance cost as the tool has a significant impact on the server code. Given the magnitude of memory debuggers available nowadays, especially those that are provided with the platform malloc implementation, maintenance of a in-house and largely obsolete memory debugger becomes a burden that is not worth the effort due to its slowness and lack of support for detecting more common forms of heap corruption. Since there are third-party tools that can provide the same functionality at a lower or comparable performance cost, the solution is to simply remove safemalloc. Third-party tools can provide the same functionality at a lower or comparable performance cost. The removal of safemalloc also allows a simplification of the malloc wrappers, removing quite a bit of kludge: redefinition of my_malloc, my_free and the removal of the unused second argument of my_free. Since free() always check whether the supplied pointer is null, redudant checks are also removed. Also, this patch adds unit testing for my_malloc and moves my_realloc implementation into the same file as the other memory allocation primitives. client/mysqldump.c: Pass my_free directly as its signature is compatible with the callback type -- which wasn't the case for free_table_ent.	16 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.

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

Mattias Jonsson	47906997c7	Bug#51851: Server with SBR locks mutex twice on LOAD DATA into partitioned MyISAM table Problem was that the ha_data structure was introduced in 5.1 and only used for partitioning first, but with the intention of be of use for others engines as well, and when used by other engines it would clash if it also was partitioned.

The overall objective of this change is to provide groundwork for the design of transactional DDL locking by cleaning up the transaction high level API to better distinguish operations implicit and explicit, and single statement transaction from operations on the normal transaction.

Solution was to remove the cache and always return the table flags from the first partition (if the handler was initialized). mysql-test/r/partition_innodb_stmt.result: Bug#39084: Getting intermittent errors with statement-based binary logging New test result file. mysql-test/t/partition_innodb_stmt.test: Bug#39084: Getting intermittent errors with statement-based binary logging New test file. sql/ha_partition.cc: Bug#39084: Getting intermittent errors with statement-based binary logging Removed m_table_flags, and added m_handler_status. Added checks that all partitions have the same table flags. Moved some variable initializations. Updated some comments. Fixed typo initialise -> initialize Changed HA_EXTTA_NO_READCHECK to do nothing, since it is only used in ha_open, which is called for every partition in ::open anyway. sql/ha_partition.h: Bug#39084: Getting intermittent errors with statement-based binary logging Removed m_table_flags, and added m_handler_status. Always return the first partitions table flags, instead of using cached table flags. Added define of enabled/disabled partitioning table flags Fixed type initialise -> initialize Updated some comments. sql/handler.cc: Bug#39084: Getting intermittent errors with statement-based binary logging Fixed type initialise -> initialize. sql/handler.h: Bug#39084: Getting intermittent errors with statement-based binary logging Added comment to understand where the cached value is set.	17 years ago

Mattias Jonsson	9e71cd43f0	Bug#37453: Dropping/creating index on partitioned table with InnoDB Plugin locks table This is a pre fix update that does the change to the handler api. This is done since there are already changes in this version, so the real fix does not need to change the api. sql/handler.h: Bug#37453: Dropping/creating index on partitioned table with InnoDB Plugin locks table The check for which alter table flags a handler have is done through the handlerton, which will not work correctly for any partitioned table. It must be through the handler interface. To be able to fix this I have to add a virtual function to the handler class.	17 years ago
Guilhem Bichot	84c1fffabb	Fix for BUG#31612 "Trigger fired multiple times leads to gaps in auto_increment sequence". The bug was that if a trigger fired multiple times inside a top statement (for example top-statement is a multi-row INSERT, and trigger is ON INSERT), and that trigger inserted into an auto_increment column, then gaps could be observed in the auto_increment sequence, even if there were no other users of the database (no concurrency). It was wrong usage of THD::auto_inc_intervals_in_cur_stmt_for_binlog. Note that the fix changes "class handler", I'll tell the Storage Engine API team. mysql-test/r/trigger-trans.result: result; before the bugfix, the sequence was 1,2,4,6,8,10,12... mysql-test/t/trigger-trans.test: test for BUG#31612 sql/handler.cc: See revision comment of handler.h. As THD::auto_inc_intervals_in_cur_stmt_for_binlog is cumulative over all trigger invokations by the top statement, the second invokation of the trigger arrived in handler::update_auto_increment() with already one interval in THD::auto_inc_intervals_in_cur_stmt_for_binlog. The method thus believed it had already reserved one interval for that invokation, thus reserved a twice larger interval (heuristic when we don't know how large the interval should be: we grow by powers of two). InnoDB thus increased its internal per-table auto_increment counter by 2 while only one row was to be inserted. Hence a gap in the sequence. The fix is to use the new handler::auto_inc_intervals_count. Note that the trigger's statement knows how many rows it is going to insert, but provides estimation_rows_to_insert == 0 (see comments in sql_insert.cc why triggers don't call handler::ha_start_bulk_insert()). * removing white space at end of line * we don't need to maintain THD::auto_inc_intervals_in_cur_stmt_for_binlog if no binlogging or if row-based binlogging. Using auto_inc_intervals_count in the heuristic makes the heuristic independent of binary logging, which is good. sql/handler.h: THD::auto_inc_intervals_in_cur_stmt_for_binlog served - for binlogging - as a heuristic when we have no estimation of how many records the statement will insert. But the first goal needs to be cumulative over all statements which form a binlog event, while the second one needs to be attached to each statement. THD::auto_inc_intervals_in_cur_stmt_for_binlog is cumulative, leading to BUG#31612. So we introduce handler::auto_inc_intervals_count for the second goal. See the revision comment of handler.cc. A smaller issue was that, even when the binlog event was only one statement (no triggers, no stored functions), THD::auto_inc_intervals_in_cur_stmt.nb_elements() could be lower than the number of reserved intervals (fooling the heuristic), because its append() method collapses two contiguous intervals in one. Note that as auto_inc_intervals_count is in class 'handler' and not in class 'THD', it does not need to be handled in THD::reset\|restore_sub_statement_state(). sql/log.cc: Comment is wrong: if auto_increment is second, in handler::update_auto_increment() 'append' is false and so auto_inc_intervals_in_cur_stmt_for_binlog is empty, we do not come here. sql/sql_class.h: comment	17 years ago
Mattias Jonsson	65811a336d	Bug#37453: Dropping/creating index on partitioned table with InnoDB Plugin locks table The fast/on-line add/drop index handler calls was not implemented whithin the partitioning. This implements it in the partitioning handler. Since this is only used by the not included InnoDB plugin, there is no test case. (Have tested it manually with the plugin, and it does not allow unique indexes not including partitioning function, or removal of pk, which in innodb generates a new pk, which is not in the partitioning function.) NOTE: This introduces a new handler method, and because of that changes the storage engine api. (One cannot use a handlerton to see the capabilities of a table's handler if it is partitioned. So I added a wrapper function in the handler that defaults to the handlerton function, which the partitioning handler overrides. sql/ha_partition.cc: Bug#37453: Dropping/creating index on partitioned table with InnoDB Plugin locks table Added support for fast/on-line add/drop index. Implemented alter_table_flags as bit-or of the partitioned hton and the first partitions alter_table_flags. It is only to forward the calls for the other functions: check_if_incompatible_data add_index prepare_drop_index final_drop_index to all parts handler sql/ha_partition.h: Bug#37453: Dropping/creating index on partitioned table with InnoDB Plugin locks table Added support for fast/on-line add/drop index. sql/handler.h: Bug#37453: Dropping/creating index on partitioned table with InnoDB Plugin locks table Added the function on handler level, defaulting to use the handlerton function, but a handler can override it. Needed for partitioned tables. NOTE: Change of storage engine api. sql/sql_partition.cc: Bug#37453: Dropping/creating index on partitioned table with InnoDB Plugin locks table Using the new handler function, instead of the handlerton function. This works better with the partitioning handler. sql/sql_table.cc: Bug#37453: Dropping/creating index on partitioned table with InnoDB Plugin locks table Using the new handler function, instead of the handlerton function. This works better with the partitioning handler. Also using new process info for 'manage keys' (kind of fix for bug-37550).	17 years ago
Mattias Jonsson	be63f0af4f	Bug#38804: Query deadlock causes all tables to be inaccessible. Problem was a mutex added in bug n 27405 for solving a problem with auto_increment in partitioned innodb tables. (in ha_partition::write_row over partitions file->ha_write_row) Solution is to use the patch for bug#33479, which refines the usage of mutexes for auto_increment. Backport of bug-33479 from 6.0: Bug-33479: auto_increment failures in partitioning Several problems with auto_increment in partitioning (with MyISAM, InnoDB. Locking issues, not handling multi-row INSERTs properly etc.) Changed the auto_increment handling for partitioning: Added a ha_data variable in table_share for storage engine specific data such as auto_increment value handling in partitioning, also see WL 4305 and using the ha_data->mutex to lock around read + update. The idea is this: Store the table's reserved auto_increment value in the TABLE_SHARE and use a mutex to, lock it for reading and updating it and unlocking it, in one block. Only accessing all partitions when it is not initialized. Also allow reservations of ranges, and if no one has done a reservation afterwards, lower the reservation to what was actually used after the statement is done (via release_auto_increment from WL 3146). The lock is kept from the first reservation if it is statement based replication and a multi-row INSERT statement where the number of candidate rows to insert is not known in advance (like INSERT SELECT, LOAD DATA, unlike INSERT VALUES (row1), (row2),,(rowN)). This should also lead to better concurrancy (no need to have a mutex protection around write_row in all cases) and work with any local storage engine. mysql-test/suite/parts/inc/partition_auto_increment.inc: Bug#38804: Query deadlock causes all tables to be inaccessible.

Using the new table_share->ha_data for keeping the auto_increment value, shared by all instances of the same table. It is read+updated when holding a auto_increment specific mutex. Also added release_auto_increment to decrease gaps if possible. And a lock for multi-row INSERT statements where the number of candidate rows to insert is not known in advance (like INSERT SELECT, LOAD DATA; Unlike INSERT INTO (row1),(row2),,(rowN)).
