Konstantin Osipov	a14bbee5ab	Backport of revno ## 2617.31.1, 2617.31.3, 2617.31.4, 2617.31.5, ... 2617.31.12, 2617.31.15, 2617.31.15, 2617.31.16, 2617.43.1 - initial changeset that introduced the fix for Bug#989 and follow up fixes for all test suite failures introduced in the initial changeset. ------------------------------------------------------------ revno: 2617.31.1 committer: Davi Arnaut <Davi.Arnaut@Sun.COM> branch nick: 4284-6.0 timestamp: Fri 2009-03-06 19:17:00 -0300 message: Bug#989: If DROP TABLE while there's an active transaction, wrong binlog order WL#4284: Transactional DDL locking Currently the MySQL server does not keep metadata locks on schema objects for the duration of a transaction, thus failing to guarantee the integrity of the schema objects being used during the transaction and to protect then from concurrent DDL operations. This also poses a problem for replication as a DDL operation might be replicated even thought there are active transactions using the object being modified. The solution is to defer the release of metadata locks until a active transaction is either committed or rolled back. This prevents other statements from modifying the table for the entire duration of the transaction. This provides commitment ordering for guaranteeing serializability across multiple transactions. - Incompatible change: If MySQL's metadata locking system encounters a lock conflict, the usual schema is to use the try and back-off technique to avoid deadlocks -- this schema consists in releasing all locks and trying to acquire them all in one go. But in a transactional context this algorithm can't be utilized as its not possible to release locks acquired during the course of the transaction without breaking the transaction commitments. To avoid deadlocks in this case, the ER_LOCK_DEADLOCK will be returned if a lock conflict is encountered during a transaction. Let's consider an example: A transaction has two statements that modify table t1, then table t2, and then commits. The first statement of the transaction will acquire a shared metadata lock on table t1, and it will be kept utill COMMIT to ensure serializability. At the moment when the second statement attempts to acquire a shared metadata lock on t2, a concurrent ALTER or DROP statement might have locked t2 exclusively. The prescription of the current locking protocol is that the acquirer of the shared lock backs off -- gives up all his current locks and retries. This implies that the entire multi-statement transaction has to be rolled back. - Incompatible change: FLUSH commands such as FLUSH PRIVILEGES and FLUSH TABLES WITH READ LOCK won't cause locked tables to be implicitly unlocked anymore. mysql-test/extra/binlog_tests/drop_table.test: Add test case for Bug#989. mysql-test/extra/binlog_tests/mix_innodb_myisam_binlog.test: Fix test case to reflect the fact that transactions now hold metadata locks for the duration of a transaction. mysql-test/include/mix1.inc: Fix test case to reflect the fact that transactions now hold metadata locks for the duration of a transaction. mysql-test/include/mix2.inc: Fix test case to reflect the fact that transactions now hold metadata locks for the duration of a transaction. mysql-test/r/flush_block_commit.result: Update test case result (WL#4284). mysql-test/r/flush_block_commit_notembedded.result: Update test case result (WL#4284). mysql-test/r/innodb.result: Update test case result (WL#4284). mysql-test/r/innodb_mysql.result: Update test case result (WL#4284). mysql-test/r/lock.result: Add test case result for an effect of WL#4284/Bug#989 (all locks should be released when a connection terminates). mysql-test/r/mix2_myisam.result: Update test case result (effects of WL#4284/Bug#989). mysql-test/r/not_embedded_server.result: Update test case result (effects of WL#4284/Bug#989). Add a test case for interaction of WL#4284 and FLUSH PRIVILEGES. mysql-test/r/partition_innodb_semi_consistent.result: Update test case result (effects of WL#4284/Bug#989). mysql-test/r/partition_sync.result: Temporarily disable the test case for Bug#43867, which will be fixed by a subsequent backport. mysql-test/r/ps.result: Add a test case for effect of PREPARE on transactional locks: we take a savepoint at beginning of PREAPRE and release it at the end. Thus PREPARE does not accumulate metadata locks (Bug#989/WL#4284). mysql-test/r/read_only_innodb.result: Update test case result (effects of WL#4284/Bug#989). mysql-test/suite/binlog/r/binlog_row_drop_tbl.result: Add a test case result (WL#4284/Bug#989). mysql-test/suite/binlog/r/binlog_row_mix_innodb_myisam.result: Update test case result (effects of WL#4284/Bug#989). mysql-test/suite/binlog/r/binlog_stm_drop_tbl.result: Add a test case result (WL#4284/Bug#989). mysql-test/suite/binlog/r/binlog_stm_mix_innodb_myisam.result: Update test case result (effects of WL#4284/Bug#989). mysql-test/suite/binlog/r/binlog_unsafe.result: A side effect of Bug#989 -- slightly different table map ids. mysql-test/suite/binlog/t/binlog_row_drop_tbl.test: Add a test case for WL#4284/Bug#989. mysql-test/suite/binlog/t/binlog_stm_drop_tbl.test: Add a test case for WL#4284/Bug#989. mysql-test/suite/binlog/t/binlog_stm_row.test: Update to the new state name. This is actually a follow up to another patch for WL#4284, that changes Locked thread state to Table lock. mysql-test/suite/ndb/r/ndb_index_ordered.result: Remove result for disabled part of the test case. mysql-test/suite/ndb/t/disabled.def: Temporarily disable a test case (Bug#45621). mysql-test/suite/ndb/t/ndb_index_ordered.test: Disable a part of a test case (needs update to reflect semantics of Bug#989). mysql-test/suite/rpl/t/disabled.def: Disable tests made meaningless by transactional metadata locking. mysql-test/suite/sys_vars/r/autocommit_func.result: Add a commit (Bug#989). mysql-test/suite/sys_vars/t/autocommit_func.test: Add a commit (Bug#989). mysql-test/t/flush_block_commit.test: Fix test case to reflect the fact that transactions now hold metadata locks for the duration of a transaction. mysql-test/t/flush_block_commit_notembedded.test: Fix test case to reflect the fact that transactions now hold metadata locks for the duration of a transaction. Add a test case for transaction-scope locks and the global read lock (Bug#989/WL#4284). mysql-test/t/innodb.test: Fix test case to reflect the fact that transactions now hold metadata locks for the duration of a transaction (effects of Bug#989/WL#4284). mysql-test/t/lock.test: Add a test case for Bug#989/WL#4284. mysql-test/t/not_embedded_server.test: Add a test case for Bug#989/WL#4284. mysql-test/t/partition_innodb_semi_consistent.test: Replace TRUNCATE with DELETE, to not issue an implicit commit of a transaction, and not depend on metadata locks. mysql-test/t/partition_sync.test: Temporarily disable the test case for Bug#43867, which needs a fix to be backported from 6.0. mysql-test/t/ps.test: Add a test case for semantics of PREPARE and transaction-scope locks: metadata locks on tables used in PREPARE are enclosed into a temporary savepoint, taken at the beginning of PREPARE, and released at the end. Thus PREPARE does not effect what locks a transaction owns. mysql-test/t/read_only_innodb.test: Fix test case to reflect the fact that transactions now hold metadata locks for the duration of a transaction (Bug#989/WL#4284). Wait for the read_only statement to actually flush tables before sending other concurrent statements that depend on its state. mysql-test/t/xa.test: Fix test case to reflect the fact that transactions now hold metadata locks for the duration of a transaction (Bug#989/WL#4284). sql/ha_ndbcluster_binlog.cc: Backport bits of changes of ha_ndbcluster_binlog.cc from 6.0, to fix the failing binlog test suite with WL#4284. WL#4284 implementation does not work with 5.1 implementation of ndbcluster binlog index. sql/log_event.cc: Release metadata locks after issuing a commit. sql/mdl.cc: Style changes (WL#4284). sql/mysql_priv.h: Rename parameter to match the name used in the definition (WL#4284). sql/rpl_injector.cc: Release metadata locks on commit (WL#4284). sql/rpl_rli.cc: Remove assert made meaningless, metadata locks are released at the end of the transaction. sql/set_var.cc: Close tables and release locks if autocommit mode is set. sql/slave.cc: Release metadata locks after a rollback. sql/sql_acl.cc: Don't implicitly unlock locked tables. Issue a implicit commit at the end and unlock tables. sql/sql_base.cc: Defer the release of metadata locks when closing tables if not required to. Issue a deadlock error if the locking protocol requires that a transaction re-acquire its locks. Release metadata locks when closing tables for reopen. sql/sql_class.cc: Release metadata locks if the thread is killed. sql/sql_parse.cc: Release metadata locks after implicitly committing a active transaction, or after explicit commits or rollbacks. sql/sql_plugin.cc: Allocate MDL request on the stack as the use of the table is contained within the function. It will be removed from the context once close_thread_tables is called at the end of the function. sql/sql_prepare.cc: The problem is that the prepare phase of the CREATE TABLE statement takes a exclusive metadata lock lock and this can cause a self-deadlock the thread already holds a shared lock on the table being that should be created. The solution is to make the prepare phase take a shared metadata lock when preparing a CREATE TABLE statement. The execution of the statement will still acquire a exclusive lock, but won't cause any problem as it issues a implicit commit. After some discussions with stakeholders it has been decided that metadata locks acquired during a PREPARE statement must be released once the statement is prepared even if it is prepared within a multi statement transaction. sql/sql_servers.cc: Don't implicitly unlock locked tables. Issue a implicit commit at the end and unlock tables. sql/sql_table.cc: Close table and release metadata locks after a admin operation. sql/table.h: The problem is that the prepare phase of the CREATE TABLE statement takes a exclusive metadata lock lock and this can cause a self-deadlock the thread already holds a shared lock on the table being that should be created. The solution is to make the prepare phase take a shared metadata lock when preparing a CREATE TABLE statement. The execution of the statement will still acquire a exclusive lock, but won't cause any problem as it issues a implicit commit. sql/transaction.cc: Release metadata locks after the implicitly committed due to a new transaction being started. Also, release metadata locks acquired after a savepoint if the transaction is rolled back to the save point. The problem is that in some cases transaction-long metadata locks could be released before the transaction was committed. This could happen when a active transaction was ended by a "START TRANSACTION" or "BEGIN" statement, in which case the metadata locks would be released before the actual commit of the active transaction. The solution is to defer the release of metadata locks to after the transaction has been implicitly committed. No test case is provided as the effort to provide one is too disproportional to the size of the fix.	2009-12-05 02:02:48 +03:00
Alfranio Correia	a4c50983f4	BUG#45292 orphan binary log created when starting server twice ... This patch fixes three bugs as follows. First, aborting the server while purging binary logs might generate orphan files due to how the purge operation was implemented: (purge routine - sql/log.cc - MYSQL_BIN_LOG::purge_logs) 1 - register the files to be removed in a temporary buffer. 2 - update the log-bin.index. 3 - flush the log-bin.index. 4 - erase the files whose names where register in the temporary buffer in step 1. Thus a failure while executing step 4 would generate an orphan file. Second, a similar issue might happen while creating a new binary as follows: (create routine - sql/log.cc - MYSQL_BIN_LOG::open) 1 - open the new log-bin. 2 - update the log-bin.index. Thus a failure while executing step 1 would generate an orphan file. To fix these issues, we record the files to be purged or created before really removing or adding them. So if a failure happens such records can be used to automatically remove dangling files. The new steps might be outlined as follows: (purge routine - sql/log.cc - MYSQL_BIN_LOG::purge_logs) 1 - register the files to be removed in the log-bin.~rec~ placed in the data directory. 2 - update the log-bin.index. 3 - flush the log-bin.index. 4 - delete the log-bin.~rec~. (create routine - sql/log.cc - MYSQL_BIN_LOG::open) 1 - register the file to be created in the log-bin.~rec~ placed in the data directory. 2 - open the new log-bin. 3 - update the log-bin.index. 4 - delete the log-bin.~rec~. (recovery routine - sql/log.cc - MYSQL_BIN_LOG::open_index_file) 1 - open the log-bin.index. 2 - open the log-bin.~rec~. 3 - for each file in log-bin.~rec~. 3.1 Check if the file is in the log-bin.index and if so ignore it. 3.2 Otherwise, delete it. The third issue can be described as follows. The purge operation was allowing to remove a file in use thus leading to the loss of data and possible inconsistencies between the master and slave. Roughly, the routine was only taking into account the dump threads and so if a slave was not connect the file might be delete even though it was in use.	2009-12-04 14:40:42 +00:00

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. Having a a high-level interface for transaction management provides a better base for implementing transactional concepts that are not always tied to storage engines and also makes it easier to interect with other higher level modules of the server. client/Makefile.am: Add new file to the build. libmysqld/CMakeLists.txt: Add new file to the build. libmysqld/Makefile.am: Add new file to the build. sql/CMakeLists.txt: Add new file to the build. sql/Makefile.am: Add new file to the build. sql/handler.cc: Remove multiplexer commit or rollback function.

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".

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
unknown	b9f9fe2e1a	Bug #43913 rpl_cross_version can't pass on conflicts complainig clash with --slave-load-tm ... The 'slave_patternload_file' is assigned to the real path of the load data file when initializing the object of Relay_log_info. But the path of the load data file is not formatted to real path when executing event from relay log. So the error will be encountered if the path of the load data file is a symbolic link. Actually the global 'opt_secure_file_priv' is not formatted to real path when loading data from file. So the same thing will happen too. To fix these errors, the path of the load data file should be formatted to real path when executing event from relay log. And the 'opt_secure_file_priv' should be formatted to real path when loading data infile. mysql-test/suite/rpl/r/rpl_loaddata_symlink.result: Test result for bug#43913. mysql-test/suite/rpl/t/rpl_loaddata_symlink-master.sh: Added the test file to create a link from $MYSQLTEST_VARDIR/std_data to $MYSQLTEST_VARDIR/std_data_master_link mysql-test/suite/rpl/t/rpl_loaddata_symlink-slave.sh: Added the test file to create a link from $MYSQLTEST_VARDIR/std_data to $MYSQLTEST_VARDIR/std_data_slave_link mysql-test/suite/rpl/t/rpl_loaddata_symlink.test: Added the test file to verify if loading data infile will work fine if the path of the load data file is a symbolic link. sql/rpl_rli.cc: Added call 'my_realpath' function for avoiding sometimes the 'fn_format' function can't format real path rightly.	2009-11-28 12:43:16 +08:00
unknown	b958fc655f	Bug #34739 unexpected binlog file name when --log-bin is set to a directory name ... If --log-bin is set to a directory name with the trailing 'FN_LIBCHAR', which will be '/' on Unix like systems, and '\\' on Windows like systems. the basename of the binlog is empty so that the created files named '.000001' and '.index'. It is not expected. The same thing happened to --log-bin-index, --relay-log and --relay-log-index options. To resolve the problem, in these cases the program should report an error and abort. sql/mysqld.cc: Added a check for the value of the --log-bin and --log-bin-index arguments, if it's a directory, reports an error and aborts. sql/rpl_rli.cc: Added a check for the value of the --relay-log and --relay-log-index arguments, if it's a directory, reports an error and aborts.	2009-11-05 14:07:31 +08:00

Alfranio Correia	5c25d17c4e	BUG#43075 rpl.rpl_sync fails sporadically on pushbuild ... NOTE: Backporting the patch to next-mr. The slave was crashing while failing to execute the init_slave() function. The issue stems from two different reasons: 1 - A failure while allocating the master info structure generated a segfault due to a NULL pointer. 2 - A failure while recovering generated a segfault due to a non-initialized relay log file. In other words, the mi->init and rli->init were both set to true before executing the recovery process thus creating an inconsistent state as the relay log file was not initialized. To circumvent such problems, we refactored the recovery process which is now executed while initializing the relay log. It is ensured that the master info structure is created before accessing it and any error is propagated thus avoiding to set mi->init and rli->init to true when for instance the relay log is not initialized or the relay info is not flushed. The changes related to the refactory are described below: 1 - Removed call to init_recovery from init_slave. 2 - Changed the signature of the function init_recovery. 3 - Removed flushes. They are called while initializing the relay log and master info. 4 - Made sure that if the relay info is not flushed the mi-init and rli-init are not set to true. In this patch, we also replaced the exit(1) in the fault injection by DBUG_ABORT() to make it compliant with the code guidelines.	2009-09-30 22:41:05 +01:00
Alfranio Correia	3ab71376ce	BUG#40337 Fsyncing master and relay log to disk after every event is too slow ... NOTE: Backporting the patch to next-mr. The fix proposed in BUG#35542 and BUG#31665 introduces a performance issue when fsyncing the master.info, relay.info and relay-log.bin* after #th events. Although such solution has been proposed to reduce the probability of corrupted files due to a slave-crash, the performance penalty introduced by it has made the approach impractical for highly intensive workloads. In a nutshell, the option --syn-relay-log proposed in BUG#35542 and BUG#31665 simultaneously fsyncs master.info, relay-log.info and relay-log.bin* and this is the main source of performance issues. This patch introduces new options that give more control to the user on what should be fsynced and how often: 1) (--sync-master-info, integer) which syncs the master.info after #th event; 2) (--sync-relay-log, integer) which syncs the relay-log.bin* after #th events. 3) (--sync-relay-log-info, integer) which syncs the relay.info after #th transactions. To provide both performance and increased reliability, we recommend the following setup: 1) --sync-master-info = 0 eventually the operating system will fsync it; 2) --sync-relay-log = 0 eventually the operating system will fsync it; 3) --sync-relay-log-info = 1 fsyncs it after every transaction; Notice, that the previous setup does not reduce the probability of corrupted master.info and relay-log.bin*. To overcome the issue, this patch also introduces a recovery mechanism that right after restart throws away relay-log.bin* retrieved from a master and updates the master.info based on the relay.info: 4) (--relay-log-recovery, boolean) which enables a recovery mechanism that throws away relay-log.bin* after a crash. However, it can only recover the incorrect binlog file and position in master.info, if other informations (host, port password, etc) are corrupted or incorrect, then this recovery mechanism will fail to work.	2009-09-29 15:40:52 +01:00

unknown	b125770aaa	We are now using Valgrind rather than purify, and have for quite some time. ... Consequently, rename HAVE_purify to HAVE_valgrind, and related changes. Leave some comments about purify when not clear that they apply also to Valgrind. Fix redundant IF_VALGRIND declaration. Misc. small fixes: - Fixes for pool-of-threads patch. - Fixes for push of PBXT storage engine. - mysql-test-run.pl fix. - Fix build problem in compile-pentium64-max. BUILD/SETUP.sh: Rename purify -> valgrind. BUILD/build_mccge.sh: Rename purify -> valgrind. BUILD/compile-dist: Fix that PBXT was missing in source tarball after `BUILD/compile-dist && make dist` BUILD/compile-pentium64-max: Fix a build problem with BUILD/compile-pentium64-max on CentOS/Fedora Core 10 amd64. On these systems, there is libz.so but no libz.a. Finding libz.so, ./configure decides to use system zlib. But since BUILD/compile-pentium64-max builds a fully static binary with -all-static, the link of mysqld fails due to missing libz.a. Fix by using bundled zlib in the build script. BUILD/compile-solaris-sparc-purify: Rename purify -> valgrind. include/m_string.h: Rename purify -> valgrind. include/my_global.h: Rename purify -> valgrind. mysql-test/Makefile.am: Fix that PBXT test suite was missing from `make dist` source tarball. mysql-test/lib/mtr_unique.pm: Better fix to avoid races when chmod'ing the semaphore file.

Alfranio Correia	f6eb9426ce	BUG#43949 Initialization of slave produces a warning message in Valgrind ... In order to define the --slave-load-tmpdir, the init_relay_log_file() was calling fn_format(MY_PACK_FILENAME) which internally was indirectly calling strmov_overlapp() (through pack_dirname) and the following warning message was being printed out while running in Valgrind: "source and destination overlap in strcpy". We fixed the issue by removing the flag MY_PACK_FILENAME as it was not necessary. In a nutshell, with this flag the function fn_format() tried to replace a directory by either "~", "." or "..". However, we wanted exactly to remove such strings. In this patch, we also refactored the functions init_relay_log_file() and check_temp_dir(). The former was refactored to call the fn_format() with the flag MY_SAFE_PATH along with the MY_RETURN_REAL_PATH, in order to avoid issues with long directories and return an absolute path, respectively. The flag MY_SAFE_UNPACK_FILENAME was removed too as it was responsible for removing "~", "." or ".." only from the file parameter and we wanted to remove such strings from the directory parameter in the fn_format(). This result is stored in an rli variable, which is then processed by the other function in order to verify if the directory exists and if we are able to create files in it. mysql-test/suite/rpl/t/rpl_slave_load_tmpdir_not_exist.test: Changed the output to make it consistent among different runs. mysys/mf_format.c: Replaced a return for DBUG_RETURN.	2009-04-19 02:21:33 +01:00

If secure-file-priv was set on slave, it became unable to execute LOAD DATA INFILE statements sent from master using mixed or statement-based replication.

He Zhenxing	bd35cfe22e	BUG#38734 rpl_server_id2 sync_with_master failed ... Rotate event is automatically generated and written when rotating binary log or relay log. Rotate events for relay logs are usually ignored by slave SQL thread becuase they have the same server id as that of the slave. However, if --replicate-same-server-id is enabled, rotate event for relay log would be treated as if it's a rotate event from master, and would be executed by slave to update the rli->group_master_log_name and rli->group_master_log_pos to a wrong value and cause the MASTER_POS_WAIT function to fail and return NULL. This patch fixed this problem by setting a flag bit (LOG_EVENT_RELAY_LOG_F) in the event to tell the SQL thread to ignore these Rotate events generated for relay logs. This patch also added another binlog event flag bit (LOG_EVENT_ARTIFICIAL_F) to distinquish faked events, the method used before this was by checking if log_pos was zero. sql/log.h: Add a member to MYSQL_BIN_LOG to distinguish binary log from relay log. sql/log_event.cc: Change artificial_event member to LOG_EVENT_ARTIFICIAL_F flag If LOG_EVENT_RELAY_LOG_F is set in the event flags for a rotate event, ignore it when updating position Refactored the code in Rotate_log_event::do_update_pos sql/log_event.h: Add LOG_EVENT_RELAY_LOG_F flag to Log_event flags Add RELAY_LOG flag to Rotate_log_event flags sql/sql_repl.cc: Set LOG_EVENT_ARTIFICIAL_F for fake rotate events	2008-09-28 15:34:25 +08:00
Michael Widenius	52cb0c24a6	Added versioning of Maria index ... Store max_trid in index file as state.create_trid. This is used to pack all transids in the index pages relative to max possible transid for file. Enable versioning for transactional tables with index. Tables with an auto-increment key, rtree or fulltext keys are not versioned. Changed info->lastkey to type MARIA_KEY. Removed info->lastkey_length as this is now part of info->lastkey Renamed old info->lastkey to info->lastkey_buff Use exact key lenghts for keys, not USE_WHOLE_KEY For partial key searches, use SEARCH_PART_KEY When searching to insert new key on page, use SEARCH_INSERT to mark that key has rowid Changes done in a lot of files: - Modified functions to use MARIA_KEY instead of key pointer and key length - Use keyinfo->root_lock instead of share->key_root_lock[keynr] - Simplify code by using local variable keyinfo instead if share->keyinfo[i] - Added #fdef EXTERNAL_LOCKING around removed state elements - HA_MAX_KEY_BUFF -> MARIA_MAX_KEY_BUFF (to reserve space for transid) - Changed type of 'nextflag' to uint32 to ensure all SEARCH_xxx flags fits into it .bzrignore: Added missing temporary directory extra/Makefile.am: comp_err is now deleted on make distclean include/maria.h: Added structure MARIA_KEY, which is used for intern key objects in Maria. Changed functions to take MARIA_KEY as an argument instead of pointer to packed key. Changed some functions that always return true or false to my_bool. Added virtual function make_key() to avoid if in _ma_make_key() Moved rw_lock_t for locking trees from share->key_root_lock to MARIA_KEYDEF. This makes usage of the locks simpler and faster include/my_base.h: Added HA_RTREE_INDEX flag to mark rtree index. Used for easier checks in ma_check() Added SEARCH_INSERT to be used when inserting new keys Added SEARCH_PART_KEY for partial searches Added SEARCH_USER_KEY_HAS_TRANSID to be used when key we use for searching in btree has a TRANSID Added SEARCH_PAGE_KEY_HAS_TRANSID to be used when key we found in btree has a transid include/my_handler.h: Make next_flag 32 bit to make sure we can handle all SEARCH_ bits mysql-test/include/maria_empty_logs.inc: Read and restore current database; Don't assume we are using mysqltest.

Added SEARCH_INSERT flag to be used when inserting new keys in btree. This flag tells us the that the keys includes row position and it's thus safe to remove SEARCH_FIND Added comparision of transid. This is only done if the keys actually have a transid, which is indicated by nextflag mysys/my_lock.c: Fixed wrong test (Found by Guilhem) scripts/Makefile.am: Ensure that test programs are deleted by make clean sql/rpl_rli.cc: Moved assignment order to fix compiler warning storage/heap/hp_write.c: Add SEARCH_INSERT to signal ha_key_cmp that we we should also compare rowid for keys storage/maria/Makefile.am: Remove also maria log files when doing make distclean storage/maria/ha_maria.cc: Use 'file->start_state' as default state for transactional tables without versioning At table unlock, set file->state to point to live state. (Needed for information schema to pick up right number of rows) In ha_maria::implicit_commit() move all locked (ie open) tables to new transaction. This is needed to ensure ha_maria->info doesn't point to a deleted history event.

unknown	2a0d2fef51	Bug#12713 "Error in a stored function called from a SELECT doesn't ... cause ROLLBACK of statement", part 1. Review fixes. Do not send OK/EOF packets to the client until we reached the end of the current statement. This is a consolidation, to keep the functionality that is shared by all SQL statements in one place in the server. Currently this functionality includes: - close_thread_tables() - log_slow_statement(). After this patch and the subsequent patch for Bug#12713, it shall also include: - ha_autocommit_or_rollback() - net_end_statement() - query_cache_end_of_result(). In future it may also include: - mysql_reset_thd_for_next_command(). include/mysql_com.h: Rename now unused members of NET: no_send_ok, no_send_error, report_error. These were server-specific variables related to the client/server protocol. They have been made obsolete by this patch. Previously the same members of NET were used to store the error message both on the client and on the server. The error message was stored in net.last_error (client: mysql->net.last_error, server: thd->net.last_error). The error code was stored in net.last_errno (client: mysql->net.last_errno, server: thd->net.last_errno). The server error code and message are now stored elsewhere (in the Diagnostics_area), thus NET members are no longer used by the server. Rename last_error to client_last_error, last_errno to client_last_errno to avoid potential bugs introduced by merges. include/mysql_h.ic: Update the ABI file to reflect a rename. Renames do not break the binary compatibility. libmysql/libmysql.c: Rename last_error to client_last_error, last_errno to client_last_errno. This is necessary to ensure no unnoticed bugs introduced by merged changesets. Remove net.report_error, net.no_send_ok, net.no_send_error. libmysql/manager.c: Rename net.last_errno to net.client_last_errno. libmysqld/lib_sql.cc: Rename net.last_errno to net.client_last_errno. Update the embedded implementation of the client-server protocol to reflect the refactoring of protocol.cc. libmysqld/libmysqld.c: Rename net.last_errno to net.client_last_errno. mysql-test/r/events.result: Update to reflect the change in mysql_rm_db(). Now we drop stored routines and events for a given database name only if there is a directory for this database name. ha_drop_database() and query_cache_invalidate() are called likewise. Previously we would attempt to drop routines/events even if database directory was not found (it worked, since routines and events are stored in tables). This fixes Bug 29958 "Weird message on DROP DATABASE if mysql.proc does not exist". The change was done because the previous code used to call send_ok() twice, which led to an assertion failure when asserts against it were added by this patch. mysql-test/r/grant.result: Fix the patch for Bug 16470, now FLUSH PRIVILEGES produces an error if mysql.procs_priv is missing. This fixes the assert that send_ok() must not called after send_error() (the original patch for Bug 16470 was prone to this). mysql-test/suite/rpl/r/rpl_row_tabledefs_2myisam.result: Produce a more detailed error message. mysql-test/suite/rpl/r/rpl_row_tabledefs_3innodb.result: Produce a more detailed error message. mysql-test/t/grant.test: Update the test, now FLUSH PRIVILEGES returns an error if mysql.procs_priv is missing. server-tools/instance-manager/mysql_connection.cc: Rename net.last_errno to net.client_last_errno. sql/ha_ndbcluster_binlog.cc: Add asserts. Use getters to access statement status information. Add a comment why run_query() is broken. Reset the diagnostics area in the end of run_query() to fulfill the invariant that the diagnostics_area is never assigned twice per statement (see the comment in the code when this can happen). We still do not clear thd->is_fatal_error and thd->is_slave_error, which may lead to bugs, I consider the whole affair as something to be dealt with separately. sql/ha_partition.cc: fatal_error() doesn't set an error by itself. Perhaps we should remove this method altogether and instead add a flag to my_error to set thd->is_fatal_error property. Meanwhile, this change is a part of inspection made to the entire source code with the goal to ensure that fatal_error() is always accompanied by my_error(). sql/item_func.cc: There is no net.last_error anymore. Remove the obsolete assignment. sql/log_event.cc: Use getters to access statement error status information. sql/log_event_old.cc: Use getters to access statement error status information. sql/mysqld.cc: Previously, if a continue handler for an error was found, my_message_sql() would not set an error in THD. Since the current statement must be aborted in any case, find_handler() had a hack to assign thd->net.report_error to 1. Remove this hack. Set an error in my_message_sql() even if the continue handler is found. The error will be cleared anyway when the handler is executed. This is one action among many in this patch to ensure the invariant that whenever thd->is_error() is TRUE, we have a message in thd->main_da.message(). sql/net_serv.cc: Use a full-blown my_error() in net_serv.cc to report an error, instead of just setting net->last_errno. This ensures the invariant that whenever thd->is_error() returns TRUE, we have a message in thd->main_da.message(). Remove initialization of removed NET members. sql/opt_range.cc: Use my_error() instead of just raising thd->net.report_error. This ensures the invariant that whenever thd->is_error() returns TRUE, there is a message in thd->main_da.message(). sql/opt_sum.cc: Move invocation of fatal_error() right next to the place where we set the error message. That makes it easier to track that whenever fatal_error() is called, there is a message in THD. sql/protocol.cc: Rename send_ok() and send_eof() to net_send_ok() and net_send_eof() respectively. These functions write directly to the network and are not for use anywhere outside the client/server protocol code. Remove the code that was responsible for cases when either there is no error code, or no error message, or both. Instead the calling code ensures that they are always present. Asserts are added to enforce the invariant. Instead of a direct access to thd->server_status and thd->total_warn_count use function parameters, since these from now on don't always come directly from THD. Introduce net_end_statement(), the single-entry-point replacement API for send_ok(), send_eof() and net_send_error(). Implement Protocol::end_partial_result_set to use in select_send::abort() when there is a continue handler. sql/protocol.h: Update declarations. sql/repl_failsafe.cc: Use getters to access statement status information in THD. Rename net.last_error to net.client_last_error. sql/rpl_record.cc: Set an error message in prepare_record() if there is no default value for the field -- later we do print this message to the client. sql/rpl_rli.cc: Use getters to access statement status information in THD. sql/slave.cc: In create_table_from_dump() (a common function that is used in LOAD MASTER TABLE SQL statement and COM_LOAD_MASTER_DATA), instead of hacks with no_send_ok, clear the diagnostics area when mysql_rm_table() succeeded. Update has_temporary_error() to work correctly when no error is set. This is the case when Incident_log_event is executed: it always returns an error but does not set an error message. Use getters to access error status information. sql/sp_head.cc: Instead of hacks with no_send_error, work through the diagnostics area interface to suppress sending of OK/ERROR packets to the client. Move query_cache_end_of_result before log_slow_statement(), similarly to how it's done in dispatch_command(). sql/sp_rcontext.cc: Remove hacks with assignment of thd->net.report_error, they are not necessary any more (see the changes in mysqld.cc). sql/sql_acl.cc: Use getters to access error status information in THD. sql/sql_base.cc: Access thd->main_da.sql_errno() only if there is an error. This fixes a bug when auto-discovery, that was effectively disabled under pre-locking. sql/sql_binlog.cc: Remove hacks with no_send_ok/no_send_error, they are not necessary anymore: the caller is responsible for network communication. sql/sql_cache.cc: Disable sending of OK/ERROR/EOF packet in the end of dispatch_command if the response has been served from the query cache. This raises the question whether we should store EOF packet in the query cache at all, or generate it anew for each statement (we should generate it anew), but this is to be addressed separately. sql/sql_class.cc: Implement class Diagnostics_area. Please see comments in sql_class.h for details. Fix a subtle coding mistake in select_send::send_data: when on slave, an error in Item::send() was ignored. The problem became visible due to asserts that the diagnostics area is never double assigned. Remove initialization of removed NET members. In select_send::abort() do not call select_send::send_eof(). This is not inheritance-safe. Even if a stored procedure continue handler is found, the current statement is aborted, not succeeded. Instead introduce a Protocol API to send the required response, Protocol::end_partial_result_set(). This simplifies implementation of select_send::send_eof(). No need to add more asserts that there is no error, there is an assert inside Diagnostics_area::set_ok_status() already. Leave no trace of no_send_* in the code. sql/sql_class.h: Declare class Diagnostics_area. Remove the hack with no_send_ok from Substatement_state. Provide inline implementations of send_ok/send_eof. Add commetns. sql/sql_connect.cc: Remove hacks with no_send_error. Since now an error in THD is always set if net->error, it's not necessary to check both net->error and thd->is_error() in the do_command loop. Use thd->main_da.message() instead of net->last_errno. Remove the hack with is_slave_error in sys_init_connect. Since now we do not reset the diagnostics area in net_send_error (it's reset at the beginning of the next statement), we can access it safely even after execute_init_command. sql/sql_db.cc: Update the code to satisfy the invariant that the diagnostics area is never assigned twice. Incidentally, this fixes Bug 29958 "Weird message on DROP DATABASE if mysql.proc does not exist". sql/sql_delete.cc: Change multi-delete to abort in abort(), as per select_send protocol. Fixes the merge error with the test for Bug 29136 sql/sql_derived.cc: Use getters to access error information. sql/sql_insert.cc: Use getters to access error information. sql-common/client.c: Rename last_error to client_last_error, last_errno to client_last_errno. sql/sql_parse.cc: Remove hacks with no_send_error. Deploy net_end_statement(). The story of COM_SHUTDOWN is interesting. Long story short, the server would become on its death's door, and only no_send_ok/no_send_error assigned by send_ok()/net_send_error() would hide its babbling from the client. First of all, COM_QUIT does not require a response. So, the comment saying "Let's send a response to possible COM_QUIT" is not only groundless (even mysqladmin shutdown/mysql_shutdown() doesn't send COM_QUIT after COM_SHUTDOWN), it's plainly incorrect. Secondly, besides this additional 'OK' packet to respond to a hypothetical COM_QUIT, there was the following code in dispatch_command(): if (thd->killed) thd->send_kill_message(); if (thd->is_error() net_send_error(thd); This worked out really funny for the thread through which COM_SHUTDOWN was delivered: we would get COM_SHUTDOWN, say okay, say okay again, kill everybody, get the kill signal ourselves, and then attempt to say "Server shutdown in progress" to the client that is very likely long gone. This all became visible when asserts were added that the Diagnostics_area is not assigned twice. Move query_cache_end_of_result() to the end of dispatch_command(), since net_send_eof() has been moved there. This is safe, query_cache_end_of_result() is a no-op if there is no started query in the cache. Consistently use select_send interface to call abort() or send_eof() depending on the operation result. Remove thd->fatal_error() from reset_master(), it was a no-op. in hacks with no_send_error woudl save us from complete breakage of the client/server protocol. Consistently use select_send::abort() whenever there is an error, and select_send::send_eof() in case of success. The issue became visible due to added asserts. sql/sql_partition.cc: Always set an error in THD whenever there is a call to fatal_error(). sql/sql_prepare.cc: Deploy class Diagnostics_area. Remove the unnecessary juggling with the protocol in Select_fetch_protocol_binary::send_eof(). EOF packet format is protocol-independent. sql/sql_select.cc: Call fatal_error() directly in opt_sum_query. Call my_error() whenever we call thd->fatal_error(). sql/sql_servers.cc: Use getters to access error information in THD. sql/sql_show.cc: Use getters to access error information in THD. Add comments. Call my_error() whenever we call fatal_error(). sql/sql_table.cc: Replace hacks with no_send_ok with the interface of the diagnostics area. Clear the error if ENOENT error in ha_delete_table(). sql/sql_update.cc: Introduce multi_update::abort(), which is the proper way to abort a multi-update. This fixes the merge conflict between this patch and the patch for Bug 29136. sql/table.cc: Use a getter to access error information in THD. sql/tztime.cc: Use a getter to access error information in THD.	2007-12-12 18:21:01 +03:00

First, there was no error code reported under conditions of the bug description although the slave sql thread halted. Second, executions were different with and without presence of prim key in the table. Third, there was no way to instruct the slave whether to ignore an error and skip to the following event or to halt. Fourth, there are handler errors which might happen due to idempotent applying of binlog but those were not listed among the "idempotent" error list. All the named issues are addressed. Wrt to the 3rd, there is the new global system variable, changeble at run time, which controls the slave sql thread behaviour. The new variable allows further extensions to mimic the sql_mode session/global variable. To address the 4th, the new bug#32468 had to be fixed as it was staying in the way. include/my_bitmap.h: basic operations with bits of an integer type are added. mysql-test/extra/rpl_tests/rpl_foreign_key.test: regression test for bug#32468 mysql-test/extra/rpl_tests/rpl_row_basic.test: changes due to bug#31552/31609 idempotency is not default any longer mysql-test/extra/rpl_tests/rpl_row_tabledefs.test: changes due to bug#31552/31609 idempotency is not default any longer mysql-test/suite/rpl/r/rpl_foreign_key_innodb.result: results changed mysql-test/suite/rpl/r/rpl_idempotency.result: results changed mysql-test/suite/rpl/r/rpl_row_basic_11bugs.result: results changed mysql-test/suite/rpl/r/rpl_row_basic_2myisam.result: results changed mysql-test/suite/rpl/r/rpl_row_basic_3innodb.result: results changed mysql-test/suite/rpl/r/rpl_row_mystery22.result: results changed mysql-test/suite/rpl/r/rpl_row_tabledefs_2myisam.result: results changed mysql-test/suite/rpl/r/rpl_row_tabledefs_3innodb.result: results changed mysql-test/suite/rpl/r/rpl_temporary_errors.result: results changed mysql-test/suite/rpl/t/rpl_idempotency.test: extenstions to the test providing testing of complements to the idempotent error set and checking how slave halts when it faces an error from the list when the mode is STRICT. mysql-test/suite/rpl/t/rpl_row_basic_11bugs.test: changes due to bug#31552/31609 idempotency is not default any longer. mysql-test/suite/rpl/t/rpl_row_mystery22.test: changes due to bug#31552/31609 idempotency is not default any longer mysql-test/suite/rpl/t/rpl_temporary_errors.test: changes due to bug#31552/31609 idempotency is not default any longer mysql-test/suite/rpl_ndb/r/rpl_ndb_dd_advance.result: results changed mysql-test/suite/rpl_ndb/r/rpl_row_basic_7ndb.result: results changed sql/log_event.cc: the fix for bug#32468 delete rows event on a table with foreign key constraint fails ensures the flags are set at proper time so that their values will be caught by innodb. reseting the flags is done along the common error and errorless execution path. The list of idempotent error is extended with foreign keys related items. NDB engine write events are designed with the replace sematics in mind. Therefore the corrsponding ndb handler's flag are (re)set regardless of the slave's execution mode. Rows_log_event::write_row() starts using the bool replace argument as its caller sets it depending on the event's execution mode. sql/log_event.h: adding a new member to hold the slave's mode during execution of the event. sql/mysql_priv.h: changes to link the command line option with the new global sys var. sql/mysqld.cc: introduction of the new command line option. providing its initialization to a default. changes to link the command line option with the new global sys var. sql/rpl_rli.cc: rli post-event-execution cleanup restores the default bits. sql/set_var.cc: The new "standard" sys_var_set class' and the new global system var related declarations and definitions. fix_slave_exec_mode() is used as with the update method of a new class so as at time of the command line arguments parsing. sql/set_var.h: new declarations. The class for the new global sys var is based on yet another new "standard" one. sql/share/errmsg.txt: slave_exec_mode setting error; slave inconsistency error which may be not an error when the intention is "idempotent". I.e consisting of row-based events binlog is being applied for the 2nd (more) time. sql/sql_class.h: The names for the bits of the new sever slave_exec_mode_options. mysql-test/suite/rpl/t/rpl_idempotency-master.opt: innodb is necessary mysql-test/suite/rpl/t/rpl_idempotency-slave.opt: innodb is necessary, as well as the tests start with non-default IDEMPOTENT slave execution mode.	2007-12-12 12:14:59 +02:00

unknown	f252f9248a	WL#3817: Simplify string / memory area types and make things more consistent (first part) ... The following type conversions was done: - Changed byte to uchar - Changed gptr to uchar* - Change my_string to char * - Change my_size_t to size_t - Change size_s to size_t Removed declaration of byte, gptr, my_string, my_size_t and size_s. Following function parameter changes was done: - All string functions in mysys/strings was changed to use size_t instead of uint for string lengths. - All read()/write() functions changed to use size_t (including vio). - All protocoll functions changed to use size_t instead of uint - Functions that used a pointer to a string length was changed to use size_t* - Changed malloc(), free() and related functions from using gptr to use void * as this requires fewer casts in the code and is more in line with how the standard functions work. - Added extra length argument to dirname_part() to return the length of the created string. - Changed (at least) following functions to take uchar* as argument: - db_dump() - my_net_write() - net_write_command() - net_store_data() - DBUG_DUMP() - decimal2bin() & bin2decimal() - Changed my_compress() and my_uncompress() to use size_t. Changed one argument to my_uncompress() from a pointer to a value as we only return one value (makes function easier to use). - Changed type of 'pack_data' argument to packfrm() to avoid casts. - Changed in readfrm() and writefrom(), ha_discover and handler::discover() the type for argument 'frmdata' to uchar** to avoid casts. - Changed most Field functions to use uchar* instead of char* (reduced a lot of casts). - Changed field->val_xxx(xxx, new_ptr) to take const pointers. Other changes: - Removed a lot of not needed casts - Added a few new cast required by other changes - Added some cast to my_multi_malloc() arguments for safety (as string lengths needs to be uint, not size_t). - Fixed all calls to hash-get-key functions to use size_t*. (Needed to be done explicitely as this conflict was often hided by casting the function to hash_get_key). - Changed some buffers to memory regions to uchar* to avoid casts. - Changed some string lengths from uint to size_t. - Changed field->ptr to be uchar* instead of char*. This allowed us to get rid of a lot of casts. - Some changes from true -> TRUE, false -> FALSE, unsigned char -> uchar - Include zlib.h in some files as we needed declaration of crc32() - Changed MY_FILE_ERROR to be (size_t) -1. - Changed many variables to hold the result of my_read() / my_write() to be size_t. This was needed to properly detect errors (which are returned as (size_t) -1). - Removed some very old VMS code - Changed packfrm()/unpackfrm() to not be depending on uint size (portability fix) - Removed windows specific code to restore cursor position as this causes slowdown on windows and we should not mix read() and pread() calls anyway as this is not thread safe. Updated function comment to reflect this. Changed function that depended on original behavior of my_pwrite() to itself restore the cursor position (one such case). - Added some missing checking of return value of malloc(). - Changed definition of MOD_PAD_CHAR_TO_FULL_LENGTH to avoid 'long' overflow. - Changed type of table_def::m_size from my_size_t to ulong to reflect that m_size is the number of elements in the array, not a string/memory length. - Moved THD::max_row_length() to table.cc (as it's not depending on THD). Inlined max_row_length_blob() into this function. - More function comments - Fixed some compiler warnings when compiled without partitions. - Removed setting of LEX_STRING() arguments in declaration (portability fix). - Some trivial indentation/variable name changes. - Some trivial code simplifications: - Replaced some calls to alloc_root + memcpy to use strmake_root()/strdup_root(). - Changed some calls from memdup() to strmake() (Safety fix) - Simpler loops in client-simple.c BitKeeper/etc/ignore: added libmysqld/ha_ndbcluster_cond.cc --- added debian/defs.mk debian/control
