Konstantin Osipov	a9013f8fba	Backport of: ... ---------------------------------------------------------- revno: 2617.23.20 committer: Konstantin Osipov <kostja@sun.com> branch nick: mysql-6.0-runtime timestamp: Wed 2009-03-04 16:31:31 +0300 message: WL#4284 "Transactional DDL locking" Review comments: "Objectify" the MDL API. MDL_request and MDL_context still need manual construction and destruction, since they are used in environment that is averse to constructors/destructors. sql/mdl.cc: Improve comments. Add asserts to backup()/restore_from_backup()/merge() methods. Fix an order bug in the error path of mdl_acquire_exclusive_locks(): we used to first free a ticket object, and only then exclude it from the list of tickets.	2009-12-04 02:52:05 +03:00
Konstantin Osipov	f477e66ec5	Backport of: ... ------------------------------------------------------------ revno: 2617.23.18 committer: Davi Arnaut <Davi.Arnaut@Sun.COM> branch nick: 4284-6.0 timestamp: Mon 2009-03-02 18:18:26 -0300 message: Bug#989: If DROP TABLE while there's an active transaction, wrong binlog order WL#4284: Transactional DDL locking This is a prerequisite patch: These changes are intended to split lock requests from granted locks and to allow the memory and lifetime of granted locks to be managed within the MDL subsystem. Furthermore, tickets can now be shared and therefore are used to satisfy multiple lock requests, but only shared locks can be recursive. The problem is that the MDL subsystem morphs lock requests into granted locks locks but does not manage the memory and lifetime of lock requests, and hence, does not manage the memory of granted locks either. This can be problematic because it puts the burden of tracking references on the users of the subsystem and it can't be easily done in transactional contexts where the locks have to be kept around for the duration of a transaction. Another issue is that recursive locks (when the context trying to acquire a lock already holds a lock on the same object) requires that each time the lock is granted, a unique lock request/granted lock structure structure must be kept around until the lock is released. This can lead to memory leaks in transactional contexts as locks taken during the transaction should only be released at the end of the transaction. This also leads to unnecessary wake ups (broadcasts) in the MDL subsystem if the context still holds a equivalent of the lock being released. These issues are exacerbated due to the fact that WL#4284 low-level design says that the implementation should "2) Store metadata locks in transaction memory root, rather than statement memory root" but this is not possible because a memory root, as implemented in mysys, requires all objects allocated from it to be freed all at once. This patch combines review input and significant code contributions from Konstantin Osipov (kostja) and Dmitri Lenev (dlenev). mysql-test/r/mdl_sync.result: Add test case result. mysql-test/t/mdl_sync.test: Add test case for shared lock upgrade case. sql/event_db_repository.cc: Rename mdl_alloc_lock to mdl_request_alloc. sql/ha_ndbcluster_binlog.cc: Use new function names to initialize MDL lock requests. sql/lock.cc: Rename MDL functions. sql/log_event.cc: The MDL request now holds the table and database name data (MDL_KEY). sql/mdl.cc: Move the MDL key to the MDL_LOCK structure in order to make the object suitable for allocation from a fixed-size allocator. This allows the simplification of the lists in the MDL_LOCK object, which now are just two, one for granted tickets and other for waiting (upgraders) tickets. Recursive requests for a shared lock on the same object can now be granted using the same lock ticket. This schema is only used for shared locks because that the only case that matters. This is used to avoid waste of resources in case a context (connection) already holds a shared lock on a object. sql/mdl.h: Introduce a metadata lock object key which is used to uniquely identify lock objects. Separate the structure used to represent pending lock requests from the structure used to represent granted metadata locks. Rename functions used to manipulate locks requests in order to have a more consistent function naming schema. sql/sp_head.cc: Rename mdl_alloc_lock to mdl_request_alloc. sql/sql_acl.cc: Rename alloc_mdl_locks to alloc_mdl_requests. sql/sql_base.cc: Various changes to accommodate that lock requests are separated from lock tickets (granted locks). sql/sql_class.h: Last acquired lock before the savepoint was set. sql/sql_delete.cc: Various changes to accommodate that lock requests are separated from lock tickets (granted locks). sql/sql_handler.cc: Various changes to accommodate that lock requests are separated from lock tickets (granted locks). sql/sql_insert.cc: Rename alloc_mdl_locks to alloc_mdl_requests. sql/sql_parse.cc: Rename alloc_mdl_locks to alloc_mdl_requests. sql/sql_plist.h: Typedef for iterator type. sql/sql_plugin.cc: Rename alloc_mdl_locks to alloc_mdl_requests. sql/sql_servers.cc: Rename alloc_mdl_locks to alloc_mdl_requests. sql/sql_show.cc: Various changes to accommodate that lock requests are separated from lock tickets (granted locks). sql/sql_table.cc: Various changes to accommodate that lock requests are separated from lock tickets (granted locks). sql/sql_trigger.cc: Save reference to the lock ticket so it can be downgraded later. sql/sql_udf.cc: Rename alloc_mdl_locks to alloc_mdl_requests. sql/table.cc: Rename mdl_alloc_lock to mdl_request_alloc. sql/table.h: Separate MDL lock requests from lock tickets (granted locks). storage/myisammrg/ha_myisammrg.cc: Rename alloc_mdl_locks to alloc_mdl_requests.	2009-12-04 02:29:40 +03:00
Konstantin Osipov	7f628ac2dd	Backport of: ... ---------------------------------------------------------- revno: 2630.4.38 committer: Konstantin Osipov <konstantin@mysql.com> branch nick: mysql-6.0-4144 timestamp: Wed 2008-06-25 22:07:06 +0400 message: WL#4144 - Lock MERGE engine children. Committing a version of the patch merged with WL#3726 on behalf of Ingo. Step #1: Move locking from parent to children. MERGE children are now left in the query list of tables after inserted there in open_tables(). So they are locked by lock_tables() as all other tables are. The MERGE parent does not store locks any more. It appears in a MYSQL_LOCK with zero lock data. This is kind of a "dummy" lock. All other lock handling is also done directly on the children. To protect against parent or child modifications during LOCK TABLES, the children are detached after every statement and attached before every statement, even under LOCK TABLES. The children table list is removed from the query list of tables on every detach and on close of the parent. Step #2: Move MERGE specific functionality from SQL layer into table handler. Functionality moved from SQL layer (mainly sql_base.cc) to the table handler (ha_myisammrg.cc). Unnecessary code is removed from the SQL layer. Step #3: Moved all MERGE specific members from TABLE to ha_myisammrg. Moved members from TABLE to ha_myisammrg. Renamed some mebers. Fixed comments. Step #4: Valgrind and coverage testing Valgrind did not uncover new problems. Added purecov comments. Added a new test for DATA/INDEX DIRECTORY options. Changed handling of ::reset() for non-attached children. Fixed the merge-big test. Step #5: Fixed crashes detected during review Changed detection when to attach/detach. Added new tests. Backport also the fix for Bug#44040 "MySQL allows creating a MERGE table upon VIEWs but crashes when using it" include/my_base.h: WL#4144 - Lock MERGE engine children Added HA_EXTRA_ADD_CHILDREN_LIST and HA_EXTRA_IS_ATTACHED_CHILDREN for MERGE table support mysql-test/r/merge.result: WL#4144 - Lock MERGE engine children Fixed test result. mysql-test/t/disabled.def: Enable merge.test, which now is working again (WL#4144). mysql-test/t/merge-big.test: Fix the messages for wait_condition (merge with WL#3726). mysql-test/t/merge.test: WL#4144 - Lock MERGE engine children Fixed one test to meet coding standards for tests (upper case keywords, engine names as in SHOW ENGINES). Fixed error codes. Added a test for DATA/INDEX DIRECTORY. mysys/thr_lock.c: WL#4144 - Lock MERGE engine children Added purecov comments. sql/ha_partition.cc: WL#4144 - Lock MERGE engine children Added MERGE specific extra operations to ha_partition::extra(). Extended comments. Changed function comment to doxygen style. Fixed nomenclature: 'parameter' -> 'operation'. sql/mysql_priv.h: WL#4144 - Lock MERGE engine children Removed declarations for removed functions. sql/sql_base.cc: WL#4144 - Lock MERGE engine children Leave the children in the query list of tables after open_tables(). Set proper back links (prev_global). Attach MERGE children before and detach them after every statement. Even under LOCK TABLES. Remove children from the query list when they are detached. Remove lock forwarding from children to parent. Moved MERGE specific functions to ha_myisammrg.cc. Added purecov comments. Backport the fix for Bug#44040 "MySQL allows creating a MERGE table upon VIEWs but crashes when using it" sql/sql_table.cc: WL#4144 - Lock MERGE engine children Changed detection of MERGE tables. sql/table.cc: WL#4144 - Lock MERGE engine children Moved is_children_attached() method from TABLE to ha_myisammrg. sql/table.h: WL#4144 - Lock MERGE engine children Moved all MERGE specific members from TABLE to ha_myisammrg. storage/myisammrg/ha_myisammrg.cc: WL#4144 - Lock MERGE engine children Set proper back links in the child list (prev_global). Added a function for removal of the child list from the query list. Remove children from the query list when the parent is closed. Make parent lock handling a dummy (zero locks). Moved MERGE specific functionality from SQL layer to here. Moved all MERGE specific members from TABLE to ha_myisammrg. Renamed children list pointers. Added initialization and free for the children list mem_root. Fixed comments. Added purecov comments. storage/myisammrg/ha_myisammrg.h: WL#4144 - Lock MERGE engine children Added method add_children_list(). Moved all MERGE specific members from TABLE to ha_myisammrg. Renamed children list pointers. Added a mem_root for the children list. storage/myisammrg/myrg_extra.c: WL#4144 - Lock MERGE engine children Changed handling of ::reset() for non-attached children.	2009-12-03 02:09:22 +03:00
Konstantin Osipov	eff3780dd8	Initial import of WL#3726 "DDL locking for all metadata objects". ... Backport of: ------------------------------------------------------------ revno: 2630.4.1 committer: Dmitry Lenev <dlenev@mysql.com> branch nick: mysql-6.0-3726-w timestamp: Fri 2008-05-23 17:54:03 +0400 message: WL#3726 "DDL locking for all metadata objects". After review fixes in progress. ------------------------------------------------------------ This is the first patch in series. It transforms the metadata locking subsystem to use a dedicated module (mdl.h,cc). No significant changes in the locking protocol. The import passes the test suite with the exception of deprecated/removed 6.0 features, and MERGE tables. The latter are subject to a fix by WL#4144. Unfortunately, the original changeset comments got lost in a merge, thus this import has its own (largely insufficient) comments. This patch fixes Bug#25144 "replication / binlog with view breaks". Warning: this patch introduces an incompatible change: Under LOCK TABLES, it's no longer possible to FLUSH a table that was not locked for WRITE. Under LOCK TABLES, it's no longer possible to DROP a table or VIEW that was not locked for WRITE. ****** Backport of: ------------------------------------------------------------ revno: 2630.4.2 committer: Dmitry Lenev <dlenev@mysql.com> branch nick: mysql-6.0-3726-w timestamp: Sat 2008-05-24 14:03:45 +0400 message: WL#3726 "DDL locking for all metadata objects".

Fix for assert failures in kill.test which occured when one tried to kill ALTER TABLE statement on merge table while it was waiting in wait_while_table_is_used() for other connections to close this table. These assert failures stemmed from the fact that cleanup code in this case assumed that temporary table representing new version of table was open with adding to THD::temporary_tables list while code which were opening this temporary table wasn't always fulfilling this. This patch changes code that opens new version of table to always do this linking in. It also streamlines cleanup process for cases when error occurs while we have new version of table open. ****** WL#3726 "DDL locking for all metadata objects" Add libmysqld/mdl.cc to .bzrignore. ****** Backport of: ------------------------------------------------------------ revno: 2630.4.6 committer: Dmitry Lenev <dlenev@mysql.com> branch nick: mysql-6.0-3726-w timestamp: Sun 2008-05-25 00:33:22 +0400 message: WL#3726 "DDL locking for all metadata objects". Addition to the fix of assert failures in kill.test caused by changes for this worklog. Make sure we close the new table only once. .bzrignore: Add libmysqld/mdl.cc libmysqld/CMakeLists.txt: Added mdl.cc to the list of files needed for building of libmysqld. libmysqld/Makefile.am: Added files implementing new meta-data locking subsystem to the server. mysql-test/include/handler.inc: Use separate connection for waiting while threads performing DDL operations conflicting with open HANDLER tables reach blocked state. This is required because now we check and close tables open by HANDLER statements in this connection conflicting with DDL in another each time open_tables() is called and thus select from I_S which is used for waiting will unblock DDL operations if issued from connection with open HANDLERs. mysql-test/r/create.result: Adjusted test case after change in implementation of CREATE TABLE ... SELECT. We no longer have special check in open_table() which catches the case when we select from the table created. Instead we rely on unique_table() call which happens after opening and locking all tables. mysql-test/r/flush.result: FLUSH TABLES WITH READ LOCK can no longer happen under LOCK TABLES. Updated test accordingly. mysql-test/r/flush_table.result: Under LOCK TABLES we no longer allow to do FLUSH TABLES for tables locked for read. Updated test accordingly. mysql-test/r/handler_innodb.result: Use separate connection for waiting while threads performing DDL operations conflicting with open HANDLER tables reach blocked state. This is required because now we check and close tables open by HANDLER statements in this connection conflicting with DDL in another each time open_tables() is called and thus select from I_S which is used for waiting will unblock DDL operations if issued from connection with open HANDLERs. mysql-test/r/handler_myisam.result: Use separate connection for waiting while threads performing DDL operations conflicting with open HANDLER tables reach blocked state. This is required because now we check and close tables open by HANDLER statements in this connection conflicting with DDL in another each time open_tables() is called and thus select from I_S which is used for waiting will unblock DDL operations if issued from connection with open HANDLERs. mysql-test/r/information_schema.result: Additional test for WL#3726 "DDL locking for all metadata objects". Check that we use high-priority metadata lock requests when filling I_S tables. Rearrange tests to match 6.0 better (fewer merge conflicts). mysql-test/r/kill.result: Added tests checking that DDL and DML statements waiting for metadata locks can be interrupted by KILL command. mysql-test/r/lock.result: One no longer is allowed to do DROP VIEW under LOCK TABLES even if this view is locked by LOCK TABLES. The problem is that in such situation write locks on view are not mutually exclusive so upgrading metadata lock which is required for dropping of view will lead to deadlock. mysql-test/r/partition_column_prune.result: Update results (same results in 6.0), WL#3726 mysql-test/r/partition_pruning.result: Update results (same results in 6.0), WL#3726 mysql-test/r/ps_ddl.result: We no longer invalidate prepared CREATE TABLE ... SELECT statement if target table changes. This is OK since it is not strictly necessary. The first change is wrong, is caused by FLUSH TABLE now flushing all unused tables. This is a regression that Dmitri fixed in 6.0 in a follow up patch. mysql-test/r/sp.result: Under LOCK TABLES we no longer allow accessing views which were not explicitly locked. To access view we need to obtain metadata lock on it and doing this under LOCK TABLES may lead to deadlocks. mysql-test/r/view.result: One no longer is allowed to do DROP VIEW under LOCK TABLES even if this view is locked by LOCK TABLES. The problem is that in such situation even "write locks" on view are not mutually exclusive so upgrading metadata lock which is required for dropping of view will lead to deadlock mysql-test/r/view_grant.result: ALTER VIEW implementation was changed to open a view only after checking that user which does alter has appropriate privileges on it. This means that in case when user's privileges are insufficient for this we won't check that new view definer is the same as original one or user performing alter has SUPER privilege. Adjusted test case accordingly. mysql-test/r/view_multi.result: Added test case for bug#25144 "replication / binlog with view breaks". mysql-test/suite/rpl/t/disabled.def: Disable test for deprecated features (they don't work with new MDL). mysql-test/t/create.test: Adjusted test case after change in implementation of CREATE TABLE ... SELECT. We no longer have special check in open_table() which catches the case when we select from the table created. Instead we rely on unique_table() call which happens after opening and locking all tables. mysql-test/t/disabled.def: Disable merge.test, subject of WL#4144 mysql-test/t/flush.test: FLUSH TABLES WITH READ LOCK can no longer happen under LOCK TABLES. Updated test accordingly. mysql-test/t/flush_table.test: Under LOCK TABLES we no longer allow to do FLUSH TABLES for tables locked for read. Updated test accordingly. mysql-test/t/information_schema.test: Additional test for WL#3726 "DDL locking for all metadata objects". Check that we use high-priority metadata lock requests when filling I_S tables. Rearrange the results for easier merges with 6.0. mysql-test/t/kill.test: Added tests checking that DDL and DML statements waiting for metadata locks can be interrupted by KILL command. mysql-test/t/lock.test: One no longer is allowed to do DROP VIEW under LOCK TABLES even if this view is locked by LOCK TABLES. The problem is that in such situation write locks on view are not mutually exclusive so upgrading metadata lock which is required for dropping of view will lead to deadlock. mysql-test/t/lock_multi.test: Adjusted test case to the changes of status in various places caused by change in implementation FLUSH TABLES WITH READ LOCK, which is now takes global metadata lock before flushing tables and therefore waits on at these places. mysql-test/t/ps_ddl.test: We no longer invalidate prepared CREATE TABLE ... SELECT statement if target table changes. This is OK since it is not strictly necessary. The first change is wrong, is caused by FLUSH TABLE now flushing all unused tables. This is a regression that Dmitri fixed in 6.0 in a follow up patch. mysql-test/t/sp.test: Under LOCK TABLES we no longer allow accessing views which were not explicitly locked.

The problem is that in such situation even "write locks" on view are not mutually exclusive so upgrading metadata lock which is required for dropping of view will lead to deadlock. mysql-test/t/view_grant.test: ALTER VIEW implementation was changed to open a view only after checking that user which does alter has appropriate privileges on it. This means that in case when user's privileges are insufficient for this we won't check that new view definer is the same as original one or user performing alter has SUPER privilege. Adjusted test case accordingly. mysql-test/t/view_multi.test: Added test case for bug#25144 "replication / binlog with view breaks". sql/CMakeLists.txt: Added mdl.cc to the list of files needed for building of server. sql/Makefile.am: Added files implementing new meta-data locking subsystem to the server. sql/event_db_repository.cc: Allocate metadata lock requests objects (MDL_LOCK) on execution memory root in cases when TABLE_LIST objects is also allocated there or on stack. sql/ha_ndbcluster.cc: Adjusted code to work nicely with new metadata locking subsystem. close_cached_tables() no longer has wait_for_placeholder argument. Instead of relying on this parameter and related behavior FLUSH TABLES WITH READ LOCK now takes global shared metadata lock. sql/ha_ndbcluster_binlog.cc: Adjusted code to work with new metadata locking subsystem. close_cached_tables() no longer has wait_for_placeholder argument. Instead of relying on this parameter and related behavior FLUSH TABLES WITH READ LOCK now takes global shared metadata lock. sql/handler.cc: update_frm_version(): Directly update TABLE_SHARE::mysql_version member instead of going through all TABLE instances for this table (old code was a legacy from pre-table-definition-cache days). sql/lock.cc: Use new metadata locking subsystem. Threw away most of functions related to name locking as now one is supposed to use metadata locking API instead. In lock_global_read_lock() and unlock_global_read_lock() in order to avoid problems with global read lock sneaking in at the moment when we perform FLUSH TABLES or ALTER TABLE under LOCK TABLES and when tables being reopened are protected only by metadata locks we also have to take global shared meta data lock. sql/log_event.cc: Adjusted code to work with new metadata locking subsystem. For tables open by slave thread for applying RBR events allocate memory for lock request object in the same chunk of memory as TABLE_LIST objects for them. In order to ensure that we keep these objects around until tables are open always close tables before calling Relay_log_info::clear_tables_to_lock(). Use new auxiliary Relay_log_info::slave_close_thread_tables() method to enforce this. sql/log_event_old.cc: Adjusted code to work with new metadata locking subsystem. Since for tables open by slave thread for applying RBR events memory for lock request object is allocated in the same chunk of memory as TABLE_LIST objects for them we have to ensure that we keep these objects around until tables are open. To ensure this we always close tables before calling Relay_log_info::clear_tables_to_lock(). To enfore this we use new auxiliary Relay_log_info::slave_close_thread_tables() method. sql/mdl.cc: Implemented new metadata locking subsystem and API described in WL3726 "DDL locking for all metadata objects". sql/mdl.h: Implemented new metadata locking subsystem and API described in WL3726 "DDL locking for all metadata objects". sql/mysql_priv.h: - close_thread_tables()/close_tables_for_reopen() now has one more argument which indicates that metadata locks should be released but not removed from the context in order to be used later in mdl_wait_for_locks() and tdc_wait_for_old_version(). - close_cached_table() routine is no longer public. - Thread waiting in wait_while_table_is_used() can be now killed so this function returns boolean to make caller aware of such situation. - We no longer have table cache as separate entity instead used and unused TABLE instances are linked to TABLE_SHARE objects in table definition cache. - Now third argument of open_table() is also used for requesting table repair or auto-discovery of table's new definition. So its type was changed from bool to enum. - Added tdc_open_view() function for opening view by getting its definition from disk (and table cache in future). - reopen_name_locked_table() no longer needs "link_in" argument as now we have exclusive metadata locks instead of dummy TABLE instances when this function is called. - find_locked_table() now takes head of list of TABLE instances instead of always scanning through THD::open_tables list. Also added find_write_locked_table() auxiliary. - reopen_tables(), close_cached_tables() no longer have mark_share_as_old and wait_for_placeholder arguments. Instead of relying on this parameters and related behavior FLUSH TABLES WITH READ LOCK now takes global shared metadata lock. - We no longer need drop_locked_tables() and abort_locked_tables(). - mysql_ha_rm_tables() now always assume that LOCK_open is not acquired by caller. - Added notify_thread_having_shared_lock() callback invoked by metadata locking subsystem when acquiring an exclusive lock, for each thread that has a conflicting shared metadata lock. - Introduced expel_table_from_cache() as replacement for remove_table_from_cache() (the main difference is that this new function assumes that caller follows metadata locking protocol and never waits). - Threw away most of functions related to name locking. One should use new metadata locking subsystem and API instead. sql/mysqld.cc: Got rid of call initializing/deinitializing table cache since now it is embedded into table definition cache. Added calls for initializing/ deinitializing metadata locking subsystem. sql/rpl_rli.cc: Introduced auxiliary Relay_log_info::slave_close_thread_tables() method which is used for enforcing that we always close tables open for RBR before deallocating TABLE_LIST elements and MDL_LOCK objects for them. sql/rpl_rli.h: Introduced auxiliary Relay_log_info::slave_close_thread_tables() method which is used for enforcing that we always close tables open for RBR before deallocating TABLE_LIST elements and MDL_LOCK objects for them. sql/set_var.cc: close_cached_tables() no longer has wait_for_placeholder argument. Instead of relying on this parameter and related behavior FLUSH TABLES WITH READ LOCK now takes global shared metadata lock. sql/sp_head.cc: For tables added to the statement's table list by prelocking algorithm we allocate these objects either on the same memory as corresponding table list elements or on THD::locked_tables_root (if we are building table list for LOCK TABLES). sql/sql_acl.cc: Allocate metadata lock requests objects (MDL_LOCK) on execution memory root in cases when we use stack TABLE_LIST objects to open tables. Got rid of redundant code by using unlock_locked_tables() function. sql/sql_base.cc: Changed code to use new MDL subsystem. Got rid of separate table cache. Now used and unused TABLE instances are linked to the TABLE_SHAREs in table definition cache. check_unused(): Adjusted code to the fact that we no longer have separate table cache. Removed dead code. table_def_free(): Free TABLE instances referenced from TABLE_SHARE objects before destroying table definition cache. get_table_share(): Added assert which ensures that noone will be able to access table (and its share) without acquiring some kind of metadata lock first. close_handle_and_leave_table_as_lock(): Adjusted code to the fact that TABLE instances now are linked to list in TABLE_SHARE. list_open_tables(): Changed this function to use table definition cache instead of table cache. free_cache_entry(): Unlink freed TABLE elements from the list of all TABLE instances for the table in TABLE_SHARE. kill_delayed_thread_for_table(): Added auxiliary for killing delayed insert threads for particular table. close_cached_tables(): Got rid of wait_for_refresh argument as we now rely on global shared metadata lock to prevent FLUSH WITH READ LOCK sneaking in when we are reopening tables. Heavily reworked this function to use new MDL code and not to rely on separate table cache entity. close_open_tables(): We no longer have separate table cache. close_thread_tables(): Release metadata locks after closing all tables. Added skip_mdl argument which allows us not to remove metadata lock requests from the context in case when we are going to use this requests later in mdl_wait_for_locks() and tdc_wait_for_old_versions(). close_thread_table()/close_table_for_reopen(): Since we no longer have separate table cache and all TABLE instances are linked to TABLE_SHARE objects in table definition cache we have to link/unlink TABLE object to/from appropriate lists in the share. name_lock_locked_table(): Moved redundant code to find_write_locked_table() function and adjusted code to the fact that wait_while_table_is_used() can now return with an error if our thread is killed. reopen_table_entry(): We no longer need "link_in" argument as with MDL we no longer call this function with dummy TABLE object pre-allocated and added to the THD::open_tables. Also now we add newly-open TABLE instance to the list of share's used TABLE instances. table_cache_insert_placeholder(): Got rid of name-locking legacy. lock_table_name_if_not_cached(): Moved to sql_table.cc the only place where it is used. It was also reimplemented using new MDL API. open_table(): - Reworked this function to use new MDL subsystem. - Changed code to deal with table definition cache directly instead of going through separate table cache. - Now third argument is also used for requesting table repair or auto-discovery of table's new definition. So its type was changed from bool to enum. find_locked_table()/find_write_locked_table(): Accept head of list of TABLE objects as first argument and use this list instead of always searching in THD::open_tables list. Also added auxiliary for finding write-locked locked tables. reopen_table(): Adjusted function to work with new MDL subsystem and to properly manuipulate with lists of used/unused TABLE instaces in TABLE_SHARE. reopen_tables(): Removed mark_share_as_old parameter. Instead of relying on it and related behavior FLUSH TABLES WITH READ LOCK now takes global shared metadata lock. Changed code after removing separate table cache. drop_locked_tables()/abort_locked_tables(): Got rid of functions which are no longer needed. unlock_locked_tables(): Moved this function from sql_parse.cc and changed it to release memory which was used for allocating metadata lock requests for tables open and locked by LOCK TABLES. tdc_open_view(): Intoduced function for opening a view by getting its definition from disk (and table cache in future). reopen_table_entry(): Introduced function for opening table definitions while holding exclusive metatadata lock on it. open_unireg_entry(): Got rid of this function. Most of its functionality is relocated to open_table() and open_table_fini() functions, and some of it to reopen_table_entry() and tdc_open_view(). Also code resposible for auto-repair and auto-discovery of tables was moved to separate function. open_table_entry_fini(): Introduced function which contains common actions which finalize process of TABLE object creation. auto_repair_table(): Moved code responsible for auto-repair of table being opened here. handle_failed_open_table_attempt() Moved code responsible for handling failing attempt to open table to one place (retry due to lock conflict/old version, auto-discovery and repair). open_tables(): - Flush open HANDLER tables if they have old version of if there is conflicting metadata lock against them (before this moment we had this code in open_table()). - When we open view which should be processed via derived table on the second execution of prepared statement or stored routine we still should call open_table() for it in order to obtain metadata lock on it and prepare its security context. - In cases when we discover that some special handling of failure to open table is needed call handle_failed_open_table_attempt() which handles all such scenarios. open_ltable(): Handling of various special scenarios of failure to open a table was moved to separate handle_failed_open_table_attempt() function. remove_db_from_cache(): Removed this function as it is no longer used. notify_thread_having_shared_lock(): Added callback which is invoked by MDL subsystem when acquiring an exclusive lock, for each thread that has a conflicting shared metadata lock. expel_table_from_cache(): Introduced function for removing unused TABLE instances. Unlike remove_table_from_cache() it relies on caller following MDL protocol and having appropriate locks when calling it and thus does not do any waiting if table is still in use. tdc_wait_for_old_version(): Added function which allows open_tables() to wait in cases when we discover that we should back-off due to presence of old version of table. abort_and_upgrade_lock(): Use new MDL calls. mysql_wait_completed_table(): Got rid of unused function. open_system_tables_for_read/for_update()/performance_schema_table(): Allocate MDL_LOCK objects on execution memory root in cases when TABLE_LIST objects for corresponding tables is allocated on stack. close_performance_schema_table(): Release metadata locks after closing tables. ****** Use I_P_List for free/used tables list in the table share. sql/sql_binlog.cc: Use Relay_log_info::slave_close_thread_tables() method to enforce that we always close tables open for RBR before deallocating TABLE_LIST elements and MDL_LOCK objects for them. sql/sql_class.cc: Added meta-data locking contexts as part of Open_tables_state context. Also introduced THD::locked_tables_root memory root which is to be used for allocating MDL_LOCK objects for tables in LOCK TABLES statement (end of lifetime for such objects is UNLOCK TABLES so we can't use statement or execution root for them). sql/sql_class.h: Added meta-data locking contexts as part of Open_tables_state context. Also introduced THD::locked_tables_root memory root which is to be used for allocating MDL_LOCK objects for tables in LOCK TABLES statement (end of lifetime for such objects is UNLOCK TABLES so we can't use statement or execution root for them). Note: handler_mdl_context and locked_tables_root and mdl_el_root will be removed by subsequent patches. sql/sql_db.cc: mysql_rm_db() does not really need to call remove_db_from_cache() as it drops each table in the database using mysql_rm_table_part2(), which performs all necessary operations on table (definition) cache. sql/sql_delete.cc: Use the new metadata locking API for TRUNCATE. sql/sql_handler.cc: Changed HANDLER implementation to use new metadata locking subsystem. Note that MDL_LOCK objects for HANDLER tables are allocated in the same chunk of heap memory as TABLE_LIST object for those tables. sql/sql_insert.cc: mysql_insert(): find_locked_table() now takes head of list of TABLE object as its argument instead of always scanning through THD::open_tables list. handle_delayed_insert(): Allocate metadata lock request object for table open by delayed insert thread on execution memroot. create_table_from_items(): We no longer allocate dummy TABLE objects for tables being created if they don't exist. As consequence reopen_name_locked_table() no longer has link_in argument. open_table() now has one more argument which is not relevant for temporary tables. sql/sql_parse.cc: - Moved unlock_locked_tables() routine to sql_base.cc and made available it in other files. Got rid of some redundant code by using this function. - Replaced boolean TABLE_LIST::create member with enum open_table_type member. - Use special memory root for allocating MDL_LOCK objects for tables open and locked by LOCK TABLES (these object should live till UNLOCK TABLES so we can't allocate them on statement nor execution memory root). Also properly set metadata lock upgradability attribure for those tables. - Under LOCK TABLES it is no longer allowed to flush tables which are not write-locked as this breaks metadata locking protocol and thus potentially might lead to deadlock. - Added auxiliary adjust_mdl_locks_upgradability() function. sql/sql_partition.cc: Adjusted code to the fact that reopen_tables() no longer has "mark_share_as_old" argument. Got rid of comments which are no longer true. sql/sql_plist.h: Added I_P_List template class for parametrized intrusive doubly linked lists and I_P_List_iterator for corresponding iterator. Unlike for I_List<> list elements of such list can participate in several lists. Unlike List<> such lists are doubly-linked and intrusive. sql/sql_plugin.cc: Allocate metadata lock requests objects (MDL_LOCK) on execution memory root in cases when we use stack TABLE_LIST objects to open tables. sql/sql_prepare.cc: Replaced boolean TABLE_LIST::create member with enum open_table_type member. This allows easily handle situation in which instead of opening the table we want only to take exclusive metadata lock on it. sql/sql_rename.cc: Use new metadata locking subsystem in implementation of RENAME TABLE. sql/sql_servers.cc: Allocate metadata lock requests objects (MDL_LOCK) on execution memory root in cases when we use stack TABLE_LIST objects to open tables. Got rid of redundant code by using unlock_locked_tables() function. sql/sql_show.cc: Acquire shared metadata lock when we are getting information for I_S table directly from TABLE_SHARE without doing full-blown table open. We use high priority lock request in this situation in order to avoid deadlocks. Also allocate metadata lock requests objects (MDL_LOCK) on execution memory root in cases when TABLE_LIST objects are also allocated there sql/sql_table.cc: mysql_rm_table(): Removed comment which is no longer relevant. mysql_rm_table_part2(): Now caller of mysql_ha_rm_tables() should not own LOCK_open. Adjusted code to use new metadata locking subsystem instead of name-locks. lock_table_name_if_not_cached(): Moved this function from sql_base.cc to this file and reimplemented it using metadata locking API. mysql_create_table(): Adjusted code to use new MDL API. wait_while_table_is_used(): Changed function to use new MDL subsystem. Made thread waiting in it killable (this also led to introduction of return value so caller can distinguish successful executions from situations when waiting was aborted). close_cached_tables(): Thread waiting in this function is killable now. As result it has return value for distinguishing between succes and failure. Got rid of redundant boradcast_refresh() call. prepare_for_repair(): Use MDL subsystem instead of name-locks. mysql_admin_table(): mysql_ha_rm_tables() now always assumes that caller doesn't own LOCK_open. mysql_repair_table(): We should mark all elements of table list as requiring upgradable metadata locks. mysql_create_table_like(): Use new MDL subsystem instead of name-locks. create_temporary_tables(): We don't need to obtain metadata locks when creating temporary table. mysql_fast_or_online_alter_table(): Thread waiting in wait_while_table_is_used() is now killable. mysql_alter_table(): Adjusted code to work with new MDL subsystem and to the fact that threads waiting in what_while_table_is_used() and close_cached_table() are now killable. sql/sql_test.cc: We no longer have separate table cache. TABLE instances are now associated with/linked to TABLE_SHARE objects in table definition cache. sql/sql_trigger.cc: Adjusted code to work with new metadata locking subsystem. Also reopen_tables() no longer has mark_share_as_old argument (Instead of relying on this parameter and related behavior FLUSH TABLES WITH READ LOCK now takes global shared metadata lock). sql/sql_udf.cc: Allocate metadata lock requests objects (MDL_LOCK) on execution memory root in cases when we use stack TABLE_LIST objects to open tables. sql/sql_update.cc: Adjusted code to work with new meta-data locking subsystem. sql/sql_view.cc: Added proper meta-data locking to implementations of CREATE/ALTER/DROP VIEW statements. Now we obtain exclusive meta-data lock on a view before creating/ changing/dropping it. This ensures that all concurrent statements that use this view will finish before our statement will proceed and therefore we will get correct order of statements in the binary log. Also ensure that TABLE_LIST::mdl_upgradable attribute is properly propagated for underlying tables of view. sql/table.cc: Added auxiliary alloc_mdl_locks() function for allocating metadata lock request objects for all elements of table list. sql/table.h: TABLE_SHARE: Got rid of unused members. Introduced members for storing lists of used and unused TABLE objects for this share. TABLE: Added members for linking TABLE objects into per-share lists of used and unused TABLE instances. Added member for holding pointer to metadata lock for this table. TABLE_LIST: Replaced boolean TABLE_LIST::create member with enum open_table_type member. This allows easily handle situation in which instead of opening the table we want only to take exclusive meta-data lock on it (we need this in order to handle ALTER VIEW and CREATE VIEW statements). Introduced new mdl_upgradable member for marking elements of table list for which we need to take upgradable shared metadata lock instead of plain shared metadata lock. Added pointer for holding pointer to MDL_LOCK for the table. Added auxiliary alloc_mdl_locks() function for allocating metadata lock requests objects for all elements of table list. Added auxiliary set_all_mdl_upgradable() function for marking all elements in table list as requiring upgradable metadata locks. storage/myisammrg/ha_myisammrg.cc: Allocate MDL_LOCK objects for underlying tables of MERGE table. To be reworked once Ingo pushes his patch for WL4144.	2009-11-30 18:55:03 +03:00

V Narayanan	0d61bd9dce	Bug#45800 crash when replacing into a merge table and there is a duplicate ... A REPLACE in the MERGE engine is actually a REPLACE into one (FIRST or LAST) of the underlying MyISAM tables. So in effect the server works on the meta data of the MERGE table, while the real insert happens in the MyISAM table. The MERGE table has no index, while MyISAM has a unique index. When a REPLACE into a MERGE table ( and the REPLACE conflicts with a duplicate in a child table) is done, we try to access the duplicate key information for the MERGE table. This information actually does not exist, hence this results in a crash. The problem can be resolved by modifying the MERGE engine to provide us the duplicate key information directly, instead of just returning the MyISAM index number as the error key. Then the SQL layer (or "the server") does not try to access the key_info of the MERGE table, which does not exist. The current patch modifies the MERGE engine to provide the position for a record where a unique key violation occurs. include/myisammrg.h: Bug#45800 crash when replacing into a merge table and there is a duplicate Add a member to the st_mymerge_info structure that will store the duplicate key offset in the MERGE table. This offset will be the sum of the record offset of the MyISAM table within the MERGE table and the offset of the record within the MyISAM table. mysql-test/r/merge.result: Bug#45800 crash when replacing into a merge table and there is a duplicate Result file for the test case. mysql-test/t/merge.test: Bug#45800 crash when replacing into a merge table and there is a duplicate Added test case for both REPLACE and INSERT...ON DUPLICATE UPDATE. storage/myisammrg/ha_myisammrg.cc: Bug#45800 crash when replacing into a merge table and there is a duplicate The info method now will process the HA_STATUS_ERRKEY flag and will return the index and the offset of the duplicate key. storage/myisammrg/ha_myisammrg.h: Bug#45800 crash when replacing into a merge table and there is a duplicate Set the HA_DUPLICATE_POS flag to indicate that the duplicate key information is now available in the MERGE storage engine. storage/myisammrg/myrg_info.c: Bug#45800 crash when replacing into a merge table and there is a duplicate We modify the myrg_status function to return the position of the duplicate key.

V Narayanan	e80537b791	Bug#40675 MySQL 5.1 crash with index merge algorithm and Merge tables ... A Query in the MyISAM merge table was crashing if the index merge algorithm was being used Index Merge optimization requires the reading of multiple indexes at the same time. Reading multiple indexes at once with current SE API means that we need to have handler instance for each to-be-read index. This is done by creating clones of the handlers instances. The clone internally does a open of the handler. The open for a MERGE engine is handled in the following phases 1) open parent table 2) generate list of underlying table 3) attach underlying tables But the current implementation does only the first phase (i.e.) open parent table. The current patch fixes this at the MERGE engine level, by handling the clone operation within the MERGE engine rather than in the storage engine API. It opens and attaches the MyISAM tables on the MyISAM storage engine interface directly within the MERGE engine. The new MyISAM table instances, as well as the MERGE clone itself, are not visible in the table cache. This is not a problem because all locking is handled by the original MERGE table from which this is cloned of. mysql-test/r/merge.result: updated the result file to reflect the new tests added to test the fix mysql-test/t/merge.test: Added new tests to verify that the index merge algorithm does not crash in the merge engine. storage/myisammrg/ha_myisammrg.cc: Implement the clone method, that handles 1) Cloning the handler 2) Opening underlying MYISAM child tables 3) Copies the state of the original handler and the children into the cloned instances 4) Sets the appropriate flags storage/myisammrg/ha_myisammrg.h: Added a flag that is set to indicate that the current instance is cloned.

unknown	5b8cdbf4a6	Fixed bug#36006: Optimizer does table scan for SELECT COUNT(*) ... for ENGINE=MRG_MYISAM (should be optimized out). Before WL#3281 MERGE engine had the HA_NOT_EXACT_COUNT flag unset, and it worked with COUNT optimization as desired. After the removal of the HA_NOT_EXACT_COUNT flag neither HA_STATS_RECORDS_IS_EXACT (opposite to former HA_NOT_EXACT_COUNT flag) nor modern HA_HAS_RECORDS flag were not added to MERGE table flag mask. 1.

unknown	e223c32077	Bug#30273 - merge tables: Can't lock file (errno: 155) ... The patch for Bug 26379 (Combination of FLUSH TABLE and REPAIR TABLE corrupts a MERGE table) fixed this bug too. However it revealed a new bug that crashed the server. Flushing a merge table at the moment when it is between open and attach of children crashed the server. The flushing thread wants to abort locks on the flushed table. It calls ha_myisammrg::lock_count() and ha_myisammrg::store_lock() on the TABLE object of the other thread. Changed ha_myisammrg::lock_count() and ha_myisammrg::store_lock() to accept non-attached children. ha_myisammrg::lock_count() returns the number of MyISAM tables in the MERGE table so that the memory allocation done by get_lock_data() is done correctly, even if the children become attached before ha_myisammrg::store_lock() is called. ha_myisammrg::store_lock() will not return any lock if the children are not attached. This is however a change in the handler interface. lock_count() can now return a higher number than store_lock() stores locks. This is more safe than the reverse implementation would be. get_lock_data() in the SQL layer is adjusted accordingly. It sets MYSQL_LOCK::lock_count based on the number of locks returned by the handler::store_lock() calls, not based on the numbers returned by the handler::lock_count() calls. The latter are only used for allocation of memory now. No test case. The test suite cannot reliably run FLUSH between lock_count() and store_lock() of another thread. The bug report contains a program that can repeat the problem with some probability. include/myisammrg.h: Bug#30273 - merge tables: Can't lock file (errno: 155) Added mutex to struct st_myrg_info (MYRG_INFO). sql/handler.h: Bug#30273 - merge tables: Can't lock file (errno: 155) Extended comments for handler::lock_count() and handler::store_lock(). sql/lock.cc: Bug#30273 - merge tables: Can't lock file (errno: 155) Changed get_lock_data() so that the final lock_count is taken from the number of locks returned from handler::store_lock() instead of from handler::lock_count(). sql/sql_base.cc: Fixed a purecov comment.

A thread trying to lock a MERGE table performs busy waiting while REPAIR TABLE or a similar table administration task is ongoing on one or more of its MyISAM tables. 2. A thread trying to lock a MERGE table performs busy waiting until all threads that did REPAIR TABLE or similar table administration tasks on one or more of its MyISAM tables in LOCK TABLES segments do UNLOCK TABLES. The difference against problem #1 is that the busy waiting takes place *after* the administration task. It is terminated by UNLOCK TABLES only. 3. Two FLUSH TABLES within a LOCK TABLES segment can invalidate the lock. This does *not* require a MERGE table. The first FLUSH TABLES can be replaced by any statement that requires other threads to reopen the table. In 5.0 and 5.1 a single FLUSH TABLES can provoke the problem. Bug 26867 - LOCK TABLES + REPAIR + merge table result in memory/cpu hogging Trying DML on a MERGE table, which has a child locked and repaired by another thread, made an infinite loop in the server. Bug 26377 - Deadlock with MERGE and FLUSH TABLE Locking a MERGE table and its children in parent-child order and flushing the child deadlocked the server. Bug 25038 - Waiting TRUNCATE Truncating a MERGE child, while the MERGE table was in use, let the truncate fail instead of waiting for the table to become free. Bug 25700 - merge base tables get corrupted by optimize/analyze/repair table Repairing a child of an open MERGE table corrupted the child. It was necessary to FLUSH the child first. Bug 30275 - Merge tables: flush tables or unlock tables causes server to crash Flushing and optimizing locked MERGE children crashed the server. Bug 19627 - temporary merge table locking Use of a temporary MERGE table with non-temporary children could corrupt the children. Temporary tables are never locked. So we do now prohibit non-temporary chidlren of a temporary MERGE table. Bug 27660 - Falcon: merge table possible It was possible to create a MERGE table with non-MyISAM children. Bug 30273 - merge tables: Can't lock file (errno: 155) This was a Windows-only bug. Table administration statements sometimes failed with "Can't lock file (errno: 155)". These bugs are fixed by a new implementation of MERGE table open. When opening a MERGE table in open_tables() we do now add the child tables to the list of tables to be opened by open_tables() (the "query_list"). The children are not opened in the handler at this stage. After opening the parent, open_tables() opens each child from the now extended query_list. When the last child is opened, we remove the children from the query_list again and attach the children to the parent. This behaves similar to the old open. However it does not open the MyISAM tables directly, but grabs them from the already open children. When closing a MERGE table in close_thread_table() we detach the children only. Closing of the children is done implicitly because they are in thd->open_tables. For more detail see the comment at the top of ha_myisammrg.cc. Changed from open_ltable() to open_and_lock_tables() in all places that can be relevant for MERGE tables. The latter can handle tables added to the list on the fly. When open_ltable() was used in a loop over a list of tables, the list must be temporarily terminated after every table for open_and_lock_tables(). table_list->required_type is set to FRMTYPE_TABLE to avoid open of special tables. Handling of derived tables is suppressed. These details are handled by the new function open_n_lock_single_table(), which has nearly the same signature as open_ltable() and can replace it in most cases. In reopen_tables() some of the tables open by a thread can be closed and reopened. When a MERGE child is affected, the parent must be closed and reopened too. Closing of the parent is forced before the first child is closed. Reopen happens in the order of thd->open_tables. MERGE parents do not attach their children automatically at open. This is done after all tables are reopened. So all children are open when attaching them. Special lock handling like mysql_lock_abort() or mysql_lock_remove() needs to be suppressed for MERGE children or forwarded to the parent. This depends on the situation. In loops over all open tables one suppresses child lock handling. When a single table is touched, forwarding is done. Behavioral changes: =================== This patch changes the behavior of temporary MERGE tables. Temporary MERGE must have temporary children. The old behavior was wrong. A temporary table is not locked. Hence even non-temporary children were not locked. See Bug 19627 - temporary merge table locking. You cannot change the union list of a non-temporary MERGE table when LOCK TABLES is in effect. The following does *not* work: CREATE TABLE m1 ... ENGINE=MRG_MYISAM ...; LOCK TABLES t1 WRITE, t2 WRITE, m1 WRITE; ALTER TABLE m1 ... UNION=(t1,t2) ...; However, you can do this with a temporary MERGE table. You cannot create a MERGE table with CREATE ... SELECT, neither as a temporary MERGE table, nor as a non-temporary MERGE table. CREATE TABLE m1 ... ENGINE=MRG_MYISAM ... SELECT ...; Gives error message: table is not BASE TABLE. include/my_base.h: Bug#26379 - Combination of FLUSH TABLE and REPAIR TABLE corrupts a MERGE table Added HA_EXTRA_ATTACH_CHILDREN and HA_EXTRA_DETACH_CHILDREN. include/myisammrg.h: Bug#26379 - Combination of FLUSH TABLE and REPAIR TABLE corrupts a MERGE table Added element 'children_attached' to MYRG_INFO.
