Patch for Bug#55850 (Trigger warnings not cleared).
The problem was that the warnings risen by a trigger were not cleared upon successful completion. The warnings should be cleared if the trigger completes successfully. The fix is to skip merging warnings into caller's Warning Info for triggers. |

A pre-requisite patch for the fix for Bug#52044.
This patch also fixes Bug#55452 "SET PASSWORD is replicated twice in RBR mode". The goal of this patch is to remove the release of metadata locks from close_thread_tables(). This is necessary to not mistakenly release the locks in the course of a multi-step operation that involves multiple close_thread_tables() or close_tables_for_reopen(). On the same token, move statement commit outside close_thread_tables(). Other cleanups: Cleanup COM_FIELD_LIST. Don't call close_thread_tables() in COM_SHUTDOWN -- there are no open tables there that can be closed (we leave the locked tables mode in THD destructor, and this close_thread_tables() won't leave it anyway). Make open_and_lock_tables() and open_and_lock_tables_derived() call close_thread_tables() upon failure. Remove the calls to close_thread_tables() that are now unnecessary. Simplify the back off condition in Open_table_context. Streamline metadata lock handling in LOCK TABLES implementation. Add asserts to ensure correct life cycle of statement transaction in a session. Remove a piece of dead code that has also become redundant after the fix for Bug 37521. mysql-test/r/variables.result: Update results: set @@autocommit and statement transaction/ prelocked mode. mysql-test/r/view.result: A harmless change in CHECK TABLE <view> status for a broken view. If previously a failure to prelock all functions used in a view would leave the connection in LTM_PRELOCKED mode, now we call close_thread_tables() from open_and_lock_tables() and leave prelocked mode, thus some check in mysql_admin_table() that works only in prelocked/locked tables mode is no longer activated. mysql-test/suite/rpl/r/rpl_row_implicit_commit_binlog.result: Fixed Bug#55452 "SET PASSWORD is replicated twice in RBR mode": extra binlog events are gone from the binary log. mysql-test/t/variables.test: Add a test case: set autocommit and statement transaction/prelocked mode. sql/event_data_objects.cc: Simplify code in Event_job_data::execute(). Move sp_head memory management to lex_end(). sql/event_db_repository.cc: Move the release of metadata locks outside close_thread_tables(). Make sure we call close_thread_tables() when open_and_lock_tables() fails and remove extra code from the events data dictionary. Use close_mysql_tables(), a new internal function to properly close mysql.* tables in the data dictionary. Contract Event_db_repository::drop_events_by_field, drop_schema_events into one function. When dropping all events in a schema, make sure we don't mistakenly release all locks acquired by DROP DATABASE. These include locks on the database name and the global intention exclusive metadata lock. sql/event_db_repository.h: Function open_event_table() does not require an instance of Event_db_repository. sql/events.cc: Use close_mysql_tables() instead of close_thread_tables() to bootstrap events, since the latter no longer releases metadata locks. sql/ha_ndbcluster.cc: - mysql_rm_table_part2 no longer releases acquired metadata locks. Do it in the caller. sql/ha_ndbcluster_binlog.cc: Deploy the new protocol for closing thread tables in run_query() and ndb_binlog_index code. sql/handler.cc: Assert that we never call ha_commit_trans/ ha_rollback_trans in sub-statement, which is now the case. sql/handler.h: Add an accessor to check whether THD_TRANS object is empty (has no transaction started). sql/log.cc: Update a comment. sql/log_event.cc: Since now we commit/rollback statement transaction in mysql_execute_command(), we need a mechanism to communicate from Query_log_event::do_apply_event() to mysql_execute_command() that the statement transaction should be rolled back, not committed. Ideally it would be a virtual method of THD. I hesitate to make THD a virtual base class in this already large patch. Use a thd->variables.option_bits for now. Remove a call to close_thread_tables() from the slave IO thread. It doesn't open any tables, and the protocol for closing thread tables is more complicated now. Make sure we properly close thread tables, however, in Load_data_log_event, which doesn't follow the standard server execution procedure with mysql_execute_command(). @todo: this piece should use Server_runnable framework instead. Remove an unnecessary call to mysql_unlock_tables(). sql/rpl_rli.cc: Update Relay_log_info::slave_close_thread_tables() to follow the new close protocol. sql/set_var.cc: Remove an unused header. sql/slave.cc: Remove an unnecessary call to close_thread_tables(). sql/sp.cc: Remove unnecessary calls to close_thread_tables() from SP DDL implementation. The tables will be closed by the caller, in mysql_execute_command(). When dropping all routines in a database, make sure to not mistakenly drop all metadata locks acquired so far, they include the scoped lock on the schema. sql/sp_head.cc: Correct the protocol that closes thread tables in an SP instruction. Clear lex->sphead before cleaning up lex with lex_end to make sure that we don't delete the sphead twice. It's considered to be "cleaner" and more in line with future changes than calling delete lex->sphead in other places that cleanup the lex. sql/sp_head.h: When destroying m_lex_keeper of an instruction, don't delete the sphead that all lex objects share. @todo: don't store a reference to routine's sp_head instance in instruction's lex. sql/sql_acl.cc: Don't call close_thread_tables() where the caller will do that for us. Fix Bug#55452 "SET PASSWORD is replicated twice in RBR mode" by disabling RBR replication in change_password() function. Use close_mysql_tables() in bootstrap and ACL reload code to make sure we release all metadata locks. sql/sql_base.cc: This is the main part of the patch: - remove manipulation with thd->transaction and thd->mdl_context from close_thread_tables(). Now this function is only responsible for closing tables, nothing else. This is necessary to be able to easily use close_thread_tables() in procedures, that involve multiple open/close tables, which all need to be protected continuously by metadata locks. Add asserts ensuring that TABLE object is only used when is protected by a metadata lock. Simplify the back off condition of Open_table_context, we no longer need to look at the autocommit mode. Make open_and_lock_tables() and open_normal_and_derived_tables() close thread tables and release metadata locks acquired so-far upon failure. This simplifies their usage. Implement close_mysql_tables(). sql/sql_base.h: Add declaration for close_mysql_tables(). sql/sql_class.cc: Remove a piece of dead code that has also become redundant after the fix for Bug 37521. The code became dead when my_eof() was made a non-protocol method, but a method that merely modifies the diagnostics area. The code became redundant with the fix for Bug#37521, when we started to cal close_thread_tables() before Protocol::end_statement(). sql/sql_do.cc: Do nothing in DO if inside a substatement (the assert moved out of trans_rollback_stmt). sql/sql_handler.cc: Add comments. sql/sql_insert.cc: Remove dead code. Release metadata locks explicitly at the end of the delayed insert thread. sql/sql_lex.cc: Add destruction of lex->sphead to lex_end(), lex "reset" method called at the end of each statement. sql/sql_parse.cc: Move close_thread_tables() and other related cleanups to mysql_execute_command() from dispatch_command(). This has become possible after the fix for Bug#37521. Mark federated SERVER statements as DDL. Next step: make sure that we don't store eof packet in the query cache, and move the query cache code outside mysql_parse. Brush up the code of COM_FIELD_LIST. Remove unnecessary calls to close_thread_tables(). When killing a query, don't report "OK" if it was a suicide. sql/sql_parse.h: Remove declaration of a function that is now static. sql/sql_partition.cc: Remove an unnecessary call to close_thread_tables(). sql/sql_plugin.cc: open_and_lock_tables() will clean up after itself after a failure. Move close_thread_tables() above end: label, and replace with close_mysql_tables(), which will also release the metadata lock on mysql.plugin. sql/sql_prepare.cc: Now that we no longer release locks in close_thread_tables() statement prepare code has become more straightforward. Remove the now redundant check for thd->killed() (used only by the backup project) from Execute_server_runnable. Reorder code to take into account that now mysql_execute_command() performs lex->unit.cleanup() and close_thread_tables(). sql/sql_priv.h: Add a new option to server options to interact between the slave SQL thread and execution framework (hack). @todo: use a virtual method of class THD instead. sql/sql_servers.cc: Due to Bug 25705 replication of DROP/CREATE/ALTER SERVER is broken. Make sure at least we do not attempt to replicate these statements using RBR, as this violates the assert in close_mysql_tables(). sql/sql_table.cc: Do not release metadata locks in mysql_rm_table_part2, this is done by the caller. Do not call close_thread_tables() in mysql_create_table(), this is done by the caller. Fix a bug in DROP TABLE under LOCK TABLES when, upon error in wait_while_table_is_used() we would mistakenly release the metadata lock on a non-dropped table. Explicitly release metadata locks when doing an implicit commit. sql/sql_trigger.cc: Now that we delete lex->sphead in lex_end(), zero the trigger's sphead in lex after loading the trigger, to avoid double deletion. sql/sql_udf.cc: Use close_mysql_tables() instead of close_thread_tables(). sql/sys_vars.cc: Remove code added in scope of WL#4284 which would break when we perform set @@session.autocommit along with setting other variables and using tables or functions. A test case added to variables.test. sql/transaction.cc: Add asserts. sql/tztime.cc: Use close_mysql_tables() rather than close_thread_tables(). |

Pre-requisite patch for bug #51263 "Deadlock between
transactional SELECT and ALTER TABLE ... REBUILD PARTITION".
The goal of this patch is to decouple type of metadata
lock acquired for table by open_tables() from type of
table-level lock to be acquired on it.
To achieve this we change approach to how we determine what
type of metadata lock should be acquired on table to be open.
Now instead of inferring it at open_tables() time from flags
and type of table-level lock we rely on that type of metadata
lock is properly set at parsing time and is not changed
further.
sql/ha_ndbcluster.cc:
Now one needs to properly initialize table list element's
MDL_request object before calling mysql_rm_table_part2().
sql/lock.cc:
lock_table_names() no longer initializes table list elements'
MDL_request objects. Now proper initialization of these
requests is a responsibility of the caller.
sql/lock.h:
Removed MYSQL_OPEN_TAKE_UPGRADABLE_MDL flag which became
unnecessary. Thanks to the fact that we don't reset type of
requests for metadata locks between re-executions we now can
figure out that upgradable locks are requested by simply
looking at their type which were set in the parser. As result
this flag became redundant.
sql/mdl.h:
Added version of new operator which simplifies allocation of
MDL_request objects on a MEM_ROOT.
sql/sp_head.cc:
Added comment explaining why it is OK to infer type of
metadata lock to request from type of table-level lock
for prelocking.
Added enum_mdl_type argument to sp_add_to_query_tables()
to simplify its usage in trigger implementation.
sql/sp_head.h:
Added enum_mdl_type argument to sp_add_to_query_tables()
to simplify its usage in trigger implementation.
sql/sql_base.cc:
- open_table_get_mdl_lock():
Preserve type of MDL_request for table list element which
was set in the parser by creating MDL_request objects on
memory root if MYSQL_OPEN_FORCE_SHARED_MDL or
MYSQL_OPEN_FORCE_SHARED_HIGH_PRIO_MDL flag were specified.
Thanks to this and to the fact that we no longer reset
type of requests for metadata locks between re-executions
we no longer need to acquire exclusive metadata lock on
table to be created in a special way. This lock is acquired
by code handling acquiring of upgradable locks.
Also changed signature/calling convention for this function
to simplify its usage.
- Accordingly special lock strategy for table list elements
which was used for such locks became unnecessary and was
removed. Other strategies were renamed.
- Since we no longer have guarantee that MDL_request object
which were not satisfied due to lock conflict belongs to
table list element Open_table_context class and its methods
were extended to remember pointer to MDL_request which has
caused problem at request_backoff_action() time and use it
in recover_from_failed_open(). Similar approach is used
for cases when problem from which we need to recover is
not related to MDL but to the table itself. In this case
we store pointer to the element of table list.
- Changed open_tables()/open_tables_check_upgradable_mdl()/
open_tables_acquire_upgradable_mdl() not to rely on
MYSQL_OPEN_TAKE_UPGRADABLE_MDL flag to understand when
upgradable metadata locks should be acquired and not to
infer type of MDL lock from type of table-level lock.
Instead we assume that type of MDL to be acquired was set
in the parser (we can do this as type of MDL_request is
no longer reset between re-executions).
sql/sql_class.h:
Since we no longer have guarantee that MDL_request object
which were not satisfied due to lock conflict belongs to
table list element Open_table_context class and its methods
were extended to remember pointer to MDL_request which has
caused problem at request_backoff_action() time and use it
in recover_from_failed_open(). Similar approach is used
for cases when problem from which we need to recover is
not related to MDL but to the table itself. In this case
we store pointer to the element of table list.
sql/sql_db.cc:
Now one needs to properly initialize table list element's
MDL_request object before calling mysql_rm_table_part2()
or mysql_rename_tables().
sql/sql_lex.cc:
st_select_lex/st_select_lex_node::add_table_to_list() method
now has argument which allows specify type of metadata lock
to be requested for table list element being added.
sql/sql_lex.h:
- st_select_lex/st_select_lex_node::add_table_to_list()
method now has argument which specifies type of metadata
lock to be requested for table list element being added.
This allows to explicitly set type of MDL lock to be
acquired for a DDL statement in parser. It is also more
future-proof than inferring type of MDL request from type
of table-level lock.
- Added Yacc_state::m_mdl_type member which specifies which
type of metadata lock should be requested for tables to be
added to table list by a grammar rule in cases when the same
rule is used in several statements requiring different kinds
of metadata locks.
sql/sql_parse.cc:
- st_select_lex::add_table_to_list() method now has argument
which specifies type of metadata lock to be requested for
table list element being added. This allows to explicitly
set type of MDL lock to be acquired for a DDL statement in
parser. It is also more future-proof than inferring type of
MDL request from type of table-level lock.
- EXCLUSIVE_DOWNGRADABLE_MDL lock strategy has a new name -
OTLS_DOWNGRADE_IF_EXISTS.
- Adjusted LOCK TABLES implementation to the fact that we no
longer infer type of metadata lock to be acquired from table
level lock and that type of MDL request is set at parsing.
And thus MYSQL_OPEN_TAKE_UPGRADABLE_MDL flag became
unnecessary.
sql/sql_prepare.cc:
TABLE_LIST's lock strategy SHARED_MDL was renamed to OTLS_NONE
as now it means that metadata lock should not be changed during
call to open_table() (if it has been already acquired) and is
also used for exclusive metadata lock.
sql/sql_show.cc:
st_select_lex::add_table_to_list() method now has argument
which specifies type of metadata lock to be requested for
table list element being added.
sql/sql_table.cc:
- Adjusted mysql_admin_table()'s code to the fact that
open_tables() no longer determines what kind of metadata
lock should be obtained basing on type of table-level
lock and flags. Instead type of metadata lock for table
to be open should be set before calling open_tables().
- Changed mysql_alter_table() code to the facts:
a) that now it is responsibility of caller to properly
initalize MDL_request in table list elements before calling
lock_table_names()
b) and that MYSQL_OPEN_TAKE_UPGRADABLE_MDL is no longer
necessary since type of metadata lock to be obtained
at open_tables() time is set during parsing.
- Changed code of mysql_recreate_table() to properly set
type of metadata and table-level lock to be obtained
by mysql_alter_table() which it calls.
sql/sql_trigger.cc:
Instead of relying on MYSQL_OPEN_TAKE_UPGRADABLE_MDL flag to
force open_tables() to take an upgradable lock we now specify
exact type of lock to be taken when constructing table list
element for table to be open for CREATE/DROP TRIGGER.
sql/sql_view.cc:
We no longer use TABLE_LIST::EXCLUSIVE_MDL strategy to force
open_tables() to take an exclusive metadata lock on view to
be created. Instead we rely on parser setting proper type of
metadata lock to request and open_tables() acquiring it.
This became possible thanks to the fact that we no longer
reset type of MDL_request between statement re-executions.
sql/sql_yacc.yy:
Instead of inferring type of MDL_request for table to be
open from type of table-level lock and flags passed to
open_tables() we now explicitly specify them at parsing.
This became possible thanks to the fact that we no longer
reset type of MDL_request between statement re-executions.
In future this should allow to decouple type of metadata
lock from type of table-level lock.
The only exception to this approach is statements implemented
through mysql_admin_table() which re-uses same table list
element several times with different types of table-level
and metadata locks.
We now also properly initialize MDL_request objects for table
list elements which are later passed to lock_table_names()
function.
sql/table.cc:
Do not reset type of MDL_request between statement
re-executions. This became unnecessesary as we no longer
change type of MDL_request residing in table list element.
In its turn this change allows to set type of MDL_request
only once - at parsing time.
sql/table.h:
Got rid of TABLE_LIST::EXCLUSIVE_MDL lock strategy.
Now we can specify that we need to acquire exclusive lock
on table to be processed by open_tables() through setting
an appropriate type of MDL_request at parsing time (this
became possible thanks to the fact that we no longer reset
types of MDL_request's belonging to table list elements
between statement re-execution).
Strategy SHARED_MDL was renamed to OTLS_NONE as now it
means that metadata lock should not be changed during call
to open_table() (if it has been already acquired) and is
also used for exclusive metadata lock.
Strategy EXCLUSIVE_DOWNGRADABLE_MDL was renamed to
OTLS_DOWNGRADE_IF_EXISTS.

Bug#50755: Crash if stored routine def contains version comments
The problem was that a syntactically invalid trigger could cause the server to crash when trying to list triggers. The crash would happen due to a mishap in the backup/restore procedure that should protect parser items which are not associated with the trigger. The backup/restore is used to isolate the parse tree (and context) of a statement from the load (and parsing) of a trigger. In this case, a error during the parsing of a trigger could cause the improper backup/restore sequence. The solution is to properly restore the original statement context before the parser is exited due to syntax errors in the trigger body. mysql-test/r/trigger.result: Add test case result for Bug#50755 mysql-test/t/trigger.test: Add test case for Bug#50755 sql/sp_head.cc: Merge sp_head::destroy() and sp_head destructor.

3655 Jon Olav Hauglid 2009-10-19 Bug #30977 Concurrent statement using stored function and DROP FUNCTION breaks SBR Bug #48246 assert in close_thread_table Implement a fix for: Bug #41804 purge stored procedure cache causes mysterious hang for many minutes Bug #49972 Crash in prepared statements The problem was that concurrent execution of DML statements that use stored functions and DDL statements that drop/modify the same function might result in incorrect binary log in statement (and mixed) mode and therefore break replication. This patch fixes the problem by introducing metadata locking for stored procedures and functions. This is similar to what is done in Bug#25144 for views. Procedures and functions now are locked using metadata locks until the transaction is either committed or rolled back. This prevents other statements from modifying the procedure/function while it is being executed. This provides commit ordering - guaranteeing serializability across multiple transactions and thus fixes the reported binlog problem. Note that we do not take locks for top-level CALLs. This means that procedures called directly are not protected from changes by simultaneous DDL operations so they are executed at the state they had at the time of the CALL. By not taking locks for top-level CALLs, we still allow transactions to be started inside procedures. This patch also changes stored procedure cache invalidation. Upon a change of cache version, we no longer invalidate the entire cache, but only those routines which we use, only when a statement is executed that uses them. This patch also changes the logic of prepared statement validation. A stored procedure used by a prepared statement is now validated only once a metadata lock has been acquired. A version mismatch causes a flush of the obsolete routine from the cache and statement reprepare. Incompatible changes: 1) ER_LOCK_DEADLOCK is reported for a transaction trying to access a procedure/function that is locked by a DDL operation in another connection. 2) Procedure/function DDL operations are now prohibited in LOCK TABLES mode as exclusive locks must be taken all at once and LOCK TABLES provides no way to specifiy procedures/functions to be locked. Test cases have been added to sp-lock.test and rpl_sp.test. Work on this bug has very much been a team effort and this patch includes and is based on contributions from Davi Arnaut, Dmitry Lenev, Magne Mæhre and Konstantin Osipov. mysql-test/r/ps_ddl.result: Update results (Bug#30977). mysql-test/r/ps_ddl1.result: Update results (Bug#30977). mysql-test/r/sp-error.result: Update results (Bug#30977). mysql-test/r/sp-lock.result: Update results (Bug#30977). mysql-test/suite/rpl/r/rpl_sp.result: Update results (Bug#30977). mysql-test/suite/rpl/t/rpl_sp.test: Add a test case for Bug#30977. mysql-test/t/ps_ddl.test: Update comments. We no longer re-prepare a prepared statement when a stored procedure used in top-level CALL is changed. mysql-test/t/ps_ddl1.test: Modifying stored procedure p1 no longer invalidates prepared statement "call p1" -- we can re-use the prepared statement without invalidation. mysql-test/t/sp-error.test: Use a constant for an error value. mysql-test/t/sp-lock.test: Add test coverage for Bug#30977. sql/lock.cc: Implement lock_routine_name() - a way to acquire an exclusive metadata lock (ex- name-lock) on stored procedure/function. sql/sp.cc: Change semantics of sp_cache_routine() -- now it has an option to make sure that the routine that is cached is up to date (has the latest sp cache version). Add sp_cache_invalidate() to sp_drop_routine(), where it was missing (a bug!). Acquire metadata locks for SP DDL (ALTER/CREATE/DROP). This is the core of the fix for Bug#30977. Since caching and cache invalidation scheme was changed, make sure we don't invalidate the SP cache in the middle of a stored routine execution. At the same time, make sure we don't access stale data due to lack of invalidation. For that, change ALTER FUNCTION/PROCEDURE to not use the cache, and SHOW PROCEDURE CODE/SHOW CREATE PROCEDURE/FUNCTION to always read an up to date version of the routine from the cache. sql/sp.h: Add a helper wrapper around sp_cache_routine(). sql/sp_cache.cc: Implement new sp_cache_version() and sp_cache_flush_obsolete(). Now we flush stale routines individually, rather than all at once. sql/sp_cache.h: Update signatures of sp_cache_version() and sp_cache_flush_obsolete(). sql/sp_head.cc: Add a default initialization of sp_head::m_sp_cache_version. Remove a redundant sp_head::create(). sql/sp_head.h: Add m_sp_cache_version to sp_head class - we now keep track of every routine in the stored procedure cache, rather than of the entire cache. sql/sql_base.cc: Implement prelocking for stored routines. Validate stored routines after they were locked. Flush obsolete routines upon next access, one by one, not all at once (Bug#41804). Style fixes. sql/sql_class.h: Rename a Open_table_context method. sql/sql_parse.cc: Make sure stored procedures DDL commits the active transaction (issues an implicit commit before and after). Remove sp_head::create(), a pure redundancy. Move the semantical check during alter routine inside sp_update_routine() code in order to: - avoid using SP cache during update, it may be obsolete. - speed up and simplify the update procedure. Remove sp_cache_flush_obsolete() calls, we no longer flush the entire cache, ever, stale routines are flushed before next use, one at a time. sql/sql_prepare.cc: Move routine metadata validation to open_and_process_routine(). Fix Bug#49972 (don't swap flags at reprepare). Reset Sroutine_hash_entries in reinit_stmt_before_use(). Remove SP cache invalidation, it's now done by open_tables(). sql/sql_show.cc: Fix a warning: remove an unused label. sql/sql_table.cc: Reset mdl_request.ticket for tickets acquired for routines inlined through a view, in CHECK TABLE statement, to satisfy an MDL assert. sql/sql_update.cc: Move the cleanup of "translation items" to close_tables_for_reopen(), since it's needed in all cases when we back off, not just the back-off in multi-update. This fixes a bug when the server would crash on attempt to back off when opening tables for a statement that uses information_schema tables. |

Added MDL_request for stored routine as member to Sroutine_hash_entry in order to be able perform metadata locking for stored routines in future (Sroutine_hash_entry is an equivalent of TABLE_LIST class for stored routines). (WL#4284, follow up fixes). sql/mdl.cc: Introduced version of MDL_request::init() method which initializes lock request using pre-built MDL key. MDL_key::table_name/table_name_length() getters were renamed to reflect the fact that MDL_key objects are now created not only for tables. sql/mdl.h: Extended enum_mdl_namespace enum with values which correspond to namespaces for stored functions and triggers. Renamed MDL_key::table_name/table_name_length() getters to MDL_key::name() and name_length() correspondingly to reflect the fact that MDL_key objects are now created not only for tables. Added MDL_key::mdl_namespace() getter. Also added version of MDL_request::init() method which initializes lock request using pre-built MDL key. sql/sp.cc: Added MDL_request for stored routine as member to Sroutine_hash_entry. Changed code to use MDL_key from this request as a key for LEX::sroutines set. Removed separate "key" member from Sroutine_hash_entry as it became unnecessary. sql/sp.h: Added MDL_request for stored routine as member to Sroutine_hash_entry in order to be able perform metadata locking for stored routines in future (Sroutine_hash_entry is an equivalent of TABLE_LIST class for stored routines). Removed Sroutine_hash_entry::key member as now we can use MDL_key from this request as a key for LEX::sroutines set. sql/sp_head.cc: Removed sp_name::m_sroutines_key member and set_routine_type() method. Since key for routine in LEX::sroutines set has no longer sp_name::m_qname as suffix we won't save anything by creating it at sp_name construction time. Adjusted sp_name constructor used for creating temporary objects for lookups in SP-cache to accept MDL_key as parameter and to avoid any memory allocation. Finally, removed sp_head::m_soutines_key member for reasons similar to why sp_name::m_sroutines_key was removed sql/sp_head.h: Removed sp_name::m_sroutines_key member and set_routine_type() method. Since key for routine in LEX::sroutines set has no longer sp_name::m_qname as suffix we won't save anything by creating it at sp_name construction time. Adjusted sp_name constructor used for creating temporary objects for lookups in SP-cache to accept MDL_key as parameter and to avoid any memory allocation. Finally, removed sp_head::m_soutines_key member for reasons similar to why sp_name::m_sroutines_key was removed. sql/sql_base.cc: Adjusted code to the fact that we now use MDL_key from Sroutine_hash_entry::mdl_request as a key for LEX::sroutines set. MDL_key::table_name/table_name_length() getters were renamed to reflect the fact that MDL_key objects are now created not only for tables. sql/sql_trigger.cc: sp_add_used_routine() now takes MDL_key as parameter as now we use instance of this class as a key for LEX::sroutines set. |

BUG#39934: Slave stops for engine that only support row-based logging
This is a post-push fix addressing review requests and
problems with extra warnings.
Problem 1: The sub-statement where an unsafe warning was detected was
printed as part of the warning. This was ok for statements that
were unsafe due to, e.g., calls to UUID(), but did not make
sense for statements that were unsafe because there was more than
one autoincrement column (unsafeness in this case comes from the
combination of several sub-statements).
Fix 1: Instead of printing the sub-statement, print an explanation
of why the statement is unsafe.
Problem 2:
When a recursive construct (i.e., stored proceure, stored
function, trigger, view, prepared statement) contained several
sub-statements, and at least one of them was unsafe, there would be
one unsafeness warning per sub-statement - even for safe
sub-statements.
Fix 2:
Ensure that each type of warning is printed at most once, by
remembering throughout the execution of the statement which types
of warnings have been printed.
mysql-test/extra/rpl_tests/create_recursive_construct.inc:
- Clarified comment per review request.
- Added checks for the number of warnings in each invocation.
mysql-test/extra/rpl_tests/rpl_insert_delayed.test:
Per review request, replaced @@session.binlog_format by
@@global.binlog_format, since INSERT DELAYED reads the global
variable. (In this test case, the two variables have the same
value, so the change is cosmetic.)
mysql-test/r/sp_trans.result:
updated result file
mysql-test/suite/binlog/r/binlog_statement_insert_delayed.result:
updated result file
mysql-test/suite/binlog/r/binlog_stm_ps.result:
updated result file
mysql-test/suite/binlog/r/binlog_stm_unsafe_warning.result:
updated result file
mysql-test/suite/binlog/r/binlog_unsafe.result:
Updated result file. Note that duplicate warnings are now gone.
mysql-test/suite/binlog/t/binlog_unsafe.test:
- Added tests for: (1) a statement that is unsafe in many ways;
(2) a statement that is unsafe in the same way several times.
- Use -- style to invoke mysqltest commands.
mysql-test/suite/rpl/r/rpl_stm_found_rows.result:
updated result file
mysql-test/suite/rpl/r/rpl_stm_loadfile.result:
updated result file
mysql-test/suite/rpl/t/rpl_mix_found_rows.test:
Per review request, added comment explaining what the test case
does (copied from rpl_stm_found_rows.test)

Clarified grammar in comment.
mysql-test/suite/rpl_ndb/r/rpl_ndb_binlog_format_errors.result:
Updated result file.
sql/item_create.cc:
Made set_stmt_unsafe take one parameter, describing the
type of unsafeness.
sql/sp_head.cc:
Added unsafe_flags field and made it hold all the unsafe flags.
sql/sp_head.h:
- Removed the BINLOG_ROW_BASED_IF_MIXED flag from m_flags.
Instead, we use the new unsafe_flags field to hold the
unsafeness state of the sp.
- Made propagate_attributes() copy all unsafe flags.
sql/sql_base.cc:
- Made LEX::set_stmt_unsafe() take an extra argument.
- Made binlog_unsafe_warning_flags store the type of unsafeness.
- Per review requests, clarified comments
- Added DBUG printouts
sql/sql_class.cc:
- Made warnings be generated in issue_warnings() and call that from
binlog_query(). Wrote issue_warnings(), which prints zero or more
warnings, avoiding to print warnings more than once per statement.
- Per review request, added @todo so that we remember to assert
correct behavior in binlog_query.
sql/sql_class.h:
- Removed BINLOG_WARNING_PRINTED
- Use [set|clear]_current_stmt_binlog_row_based() instead of
modifying the flag directly.
- added issue_unsafe_warnings() (only called from binlog_unsafe)
- Per review request, improved some documentation.
sql/sql_insert.cc:
Added extra argument to LEX::set_stmt_unsafe()
sql/sql_lex.h:
- Added enum_binlog_stmt_unsafe, listing all types of unsafe
statements.
- Per review requests, improved many comments for member
functions.
- Added [get|set]_stmt_unsafe_flags(), which return/set all the
unsafe flags for a statement.
sql/sql_parse.cc:
- Renamed binlog_warning_flags to binlog_unsafe_warning_flags.
- Per review requests, improved comment.
sql/sql_view.cc:
Made views propagate all the new unsafe flags.
sql/sql_yacc.yy:
Added parameter to set_stmt_unsafe().
storage/innobase/handler/ha_innodb.cc:
Per review requests, replaced DBUG_EXECUTE_IF() by DBUG_EVALUATE_IF().

BUG#39934: Slave stops for engine that only support row-based logging
General overview:
The logic for switching to row format when binlog_format=MIXED had
numerous flaws. The underlying problem was the lack of a consistent
architecture.
General purpose of this changeset:
This changeset introduces an architecture for switching to row format
when binlog_format=MIXED. It enforces the architecture where it has
to. It leaves some bugs to be fixed later. It adds extensive tests to
verify that unsafe statements work as expected and that appropriate
errors are produced by problems with the selection of binlog format.
It was not practical to split this into smaller pieces of work.
Problem 1:
To determine the logging mode, the code has to take several parameters
into account (namely: (1) the value of binlog_format; (2) the
capabilities of the engines; (3) the type of the current statement:
normal, unsafe, or row injection). These parameters may conflict in
several ways, namely:
- binlog_format=STATEMENT for a row injection
- binlog_format=STATEMENT for an unsafe statement
- binlog_format=STATEMENT for an engine only supporting row logging
- binlog_format=ROW for an engine only supporting statement logging
- statement is unsafe and engine does not support row logging
- row injection in a table that does not support statement logging
- statement modifies one table that does not support row logging and
one that does not support statement logging
Several of these conflicts were not detected, or were detected with
an inappropriate error message. The problem of BUG#39934 was that no
appropriate error message was written for the case when an engine
only supporting row logging executed a row injection with
binlog_format=ROW. However, all above cases must be handled.
Fix 1:
Introduce new error codes (sql/share/errmsg.txt). Ensure that all
conditions are detected and handled in decide_logging_format()
Problem 2:
The binlog format shall be determined once per statement, in
decide_logging_format(). It shall not be changed before or after that.
Before decide_logging_format() is called, all information necessary to
determine the logging format must be available. This principle ensures
that all unsafe statements are handled in a consistent way.
However, this principle is not followed:
thd->set_current_stmt_binlog_row_based_if_mixed() is called in several
places, including from code executing UPDATE..LIMIT,
INSERT..SELECT..LIMIT, DELETE..LIMIT, INSERT DELAYED, and
SET @@binlog_format. After Problem 1 was fixed, that caused
inconsistencies where these unsafe statements would not print the
appropriate warnings or errors for some of the conflicts.
Fix 2:
Remove calls to THD::set_current_stmt_binlog_row_based_if_mixed() from
code executed after decide_logging_format(). Compensate by calling the
set_current_stmt_unsafe() at parse time. This way, all unsafe statements
are detected by decide_logging_format().
Problem 3:
INSERT DELAYED is not unsafe: it is logged in statement format even if
binlog_format=MIXED, and no warning is printed even if
binlog_format=STATEMENT. This is BUG#45825.
Fix 3:
Made INSERT DELAYED set itself to unsafe at parse time. This allows
decide_logging_format() to detect that a warning should be printed or
the binlog_format changed.
Problem 4:
LIMIT clause were not marked as unsafe when executed inside stored
functions/triggers/views/prepared statements. This is
BUG#45785.
Fix 4:
Make statements containing the LIMIT clause marked as unsafe at
parse time, instead of at execution time. This allows propagating
unsafe-ness to the view.
mysql-test/extra/rpl_tests/create_recursive_construct.inc:
Added auxiliary file used by binlog_unsafe.test to create and
execute recursive constructs
(functions/procedures/triggers/views/prepared statements).
mysql-test/extra/rpl_tests/rpl_foreign_key.test:
removed unnecessary set @@session.binlog_format
mysql-test/extra/rpl_tests/rpl_insert_delayed.test:
Filter out table id from table map events in binlog listing.
Got rid of $binlog_format_statement.
mysql-test/extra/rpl_tests/rpl_ndb_apply_status.test:
disable warnings around call to unsafe procedure
mysql-test/include/rpl_udf.inc:
Disabled warnings for code that generates warnings
for some binlog formats. That would otherwise cause
inconsistencies in the result file.
mysql-test/r/mysqldump.result:
Views are now unsafe if they contain a LIMIT clause.
That fixed BUG#45831. Due to BUG#45832, a warning is
printed for the CREATE VIEW statement.
mysql-test/r/sp_trans.result:
Unsafe statements in stored procedures did not give a warning if
binlog_format=statement. This is BUG#45824. Now they do, so this
result file gets a new warning.
mysql-test/suite/binlog/r/binlog_multi_engine.result:
Error message changed.
mysql-test/suite/binlog/r/binlog_statement_insert_delayed.result:
INSERT DELAYED didn't generate a warning when binlog_format=STATEMENT.
That was BUG#45825. Now there is a warning, so result file needs to be
updated.
mysql-test/suite/binlog/r/binlog_stm_ps.result:
Changed error message.
mysql-test/suite/binlog/r/binlog_unsafe.result:
updated result file:
- error message changed
- added test for most combinations of unsafe constructs invoked
from recursive constructs
- INSERT DELAYED now gives a warning (because BUG#45826 is fixed)
- INSERT..SELECT..LIMIT now gives a warning from inside recursive
constructs (because BUG#45785 was fixed)
- When a recursive construct (e.g., stored proc or function)
contains more than one statement, at least one of which is
unsafe, then all statements in the recursive construct give
warnings. This is a new bug introduced by this changeset.
It will be addressed in a post-push fix.
mysql-test/suite/binlog/t/binlog_innodb.test:
Changed error code for innodb updates with READ COMMITTED or
READ UNCOMMITTED transaction isolation level and
binlog_format=statement.
mysql-test/suite/binlog/t/binlog_multi_engine.test:
The error code has changed for statements where more than one
engine is involved and one of them is self-logging.
mysql-test/suite/binlog/t/binlog_unsafe-master.opt:
Since binlog_unsafe now tests unsafe-ness of UDF's, we need an extra
flag in the .opt file.
mysql-test/suite/binlog/t/binlog_unsafe.test:
- Clarified comment.
- Rewrote first part of test. Now it tests not only unsafe variables
and functions, but also unsafe-ness due to INSERT..SELECT..LIMIT,
INSERT DELAYED, insert into two autoinc columns, use of UDF's, and
access to log tables in the mysql database.
Also, in addition to functions, procedures, triggers, and prepared
statements, it now also tests views; and it constructs recursive
calls in two levels by combining these recursive constructs.
Part of the logic is in extra/rpl_tests/create_recursive_construct.inc.
- added tests for all special system variables that should not be unsafe.
- added specific tests for BUG#45785 and BUG#45825
mysql-test/suite/rpl/r/rpl_events.result:
updated result file
mysql-test/suite/rpl/r/rpl_extraColmaster_innodb.result:

the second half of the old rpl_found_rows.result, with the following
modifications:
- minor formatting changes
- additional initialization
mysql-test/suite/rpl/r/rpl_mix_insert_delayed.result:
Moved out code operating in mixed mode from rpl_stm_insert_delayed

Got rid of unnecessary explicit setting of binlog format.
mysql-test/suite/rpl/r/rpl_stm_found_rows.result:
Split rpl_found_rows.test into rpl_mix_found_rows.test (a new file) and
rpl_stm_found_rows.test (renamed rpl_found_rows.test). Changes in
this file:
- minor formatting changes
- warning is now issued for unsafe statements inside procedures
(since BUG#45824 is fixed)
- second half of file is moved to rpl_mix_found_rows.result
mysql-test/suite/rpl/r/rpl_stm_insert_delayed.result:
Moved out code operating in mixed mode from rpl_stm_insert_delayed
(into rpl_mix_insert_delayed) and got rid of explicit setting of

error message changed
mysql-test/suite/rpl/r/rpl_temporary_errors.result:
updated result file
mysql-test/suite/rpl/r/rpl_udf.result:
Remove explicit set of binlog format (and triplicate test execution)
and rely on test system executing the test in all binlog formats.
mysql-test/suite/rpl/t/rpl_bug31076.test:
Test is only valid in mixed or row mode since it generates row events.
mysql-test/suite/rpl/t/rpl_events.test:
Removed explicit set of binlog_format and removed duplicate testing.
Instead, we rely on the test system to try all binlog formats.
mysql-test/suite/rpl/t/rpl_extraColmaster_innodb.test:
Removed triplicate testing and instead relying on test system.
Test is only relevant for row format since statement-based replication
cannot handle extra columns on master.
mysql-test/suite/rpl/t/rpl_extraColmaster_myisam.test:
Removed triplicate testing and instead relying on test system.
Test is only relevant for row format since statement-based replication
cannot handle extra columns on master.
mysql-test/suite/rpl/t/rpl_idempotency-slave.opt:
Removed .opt file to avoid server restarts.
mysql-test/suite/rpl/t/rpl_idempotency.test:
- Moved out row-only tests to a new test file, rpl_row_idempotency.test.
rpl_idempotency now only contains tests that execute in all
binlog_formats.
- While I was here, also removed .opt file to avoid server restarts.
The slave_exec_mode is now set inside the test instead.
mysql-test/suite/rpl/t/rpl_mix_found_rows.test:
Split rpl_found_rows.test into rpl_mix_found_rows.test (a new file) and
rpl_stm_found_rows.test (renamed rpl_found_rows.test). This file
contains the second half of the original rpl_found_rows.test with the
follwing changes:
- initialization
- removed SET_BINLOG_FORMAT and added have_binlog_format_mixed.inc
- minor formatting changes
mysql-test/suite/rpl/t/rpl_mix_insert_delayed.test:
Moved out code operating in mixed mode from rpl_stm_insert_delayed
(into rpl_mix_insert_delayed) and got rid of explicit setting of
binlog format.
mysql-test/suite/rpl/t/rpl_rbr_to_sbr.test:
Test cannot execute in statement mode, since we no longer
switch to row format when binlog_format=statement.
Enforced mixed mode throughout the test.
mysql-test/suite/rpl/t/rpl_row_idempotency.test:
Moved the second half of rpl_idempotency.test, which only
executed in row mode, to this new file. We now rely on the
test system to set binlog format.
mysql-test/suite/rpl/t/rpl_row_insert_delayed.test:
- Got rid of unnecessary explicit setting of binlog format.
- extra/rpl_tests/rpl_insert_delayed.test does not need the
$binlog_format_statement variable any more, so that was
removed.
mysql-test/suite/rpl/t/rpl_slave_skip.test:
The test switches binlog_format internally and master generates both
row and statement events. Hence, the slave must be able to log in both
statement and row format. Hence test was changed to only execute in
mixed mode.
mysql-test/suite/rpl/t/rpl_stm_found_rows.test:
Split rpl_found_rows.test into rpl_mix_found_rows.test (a new file) and

- added have_binlog_format_statement and removed SET BINLOG_FORMAT.
- second half of file is moved to rpl_mix_found_rows.test
- added cleanup code
mysql-test/suite/rpl/t/rpl_stm_insert_delayed.test:
Moved out code operating in mixed mode from rpl_stm_insert_delayed
(into rpl_mix_insert_delayed) and got rid of explicit setting of
binlog format.
mysql-test/suite/rpl/t/rpl_switch_stm_row_mixed.test:
The test switches binlog_format internally and master generates both
row and statement events. Hence, the slave must be able to log in both
statement and row format. Hence test was changed to only execute in
mixed mode on slave.
mysql-test/suite/rpl/t/rpl_temporary_errors.test:
Removed explicit set of binlog format. Instead, the test now only
executes in row mode.
mysql-test/suite/rpl/t/rpl_udf.test:
Remove explicit set of binlog format (and triplicate test execution)
and rely on test system executing the test in all binlog formats.

The test needs slave to be able to switch to row mode, so the
test was changed to only execute in mixed and row mode.
mysql-test/t/partition_innodb_stmt.test:
Changed error code for innodb updates with READ COMMITTED or
READ UNCOMMITTED transaction isolation level and
binlog_format=statement.
sql/event_db_repository.cc:
Use member function to read current_stmt_binlog_row_based.
sql/events.cc:
Use member function to read current_stmt_binlog_row_based.
sql/ha_ndbcluster_binlog.cc:
reset_current_stmt_binlog_row_based() is not a no-op for the ndb_binlog
thread any more. Instead, the ndb_binlog thread now forces row mode both
initially and just after calling mysql_parse. (mysql_parse() is the only
place where reset_current_stmt_binlog_row_based() may be called from
the ndb_binlog thread, so these are the only two places that need to
change.)
sql/ha_partition.cc:
Use member function to read current_stmt_binlog_row_based.
sql/handler.cc:
Use member function to read current_stmt_binlog_row_based.
sql/item_create.cc:
Added DBUG_ENTER to some functions, to be able to trace when
set_stmt_unsafe is called.
sql/log.cc:
Use member function to read current_stmt_binlog_row_based.
sql/log_event.cc:
- Moved logic for changing to row format out of do_apply_event (and into
decide_logging_format).
- Added @todo comment for post-push cleanup.
sql/log_event_old.cc:
Move logic for changing to row format out of do_apply_event (and into
decide_logging_format).
sql/mysql_priv.h:
Make decide_logging_format() a member of the THD class, for two reasons:
- It is natural from an object-oriented perspective.
- decide_logging_format() needs to access private members of THD
(specifically, the new binlog_warning_flags field).
sql/rpl_injector.cc:
Removed call to set_current_stmt_binlog_row_based().
From now on, only decide_logging_fromat is allowed to modify
current_stmt_binlog_row_based. This call is from the ndb_binlog
thread, mostly executing code in ha_ndbcluster_binlog.cc.
This call can be safely removed, because:
- current_stmt_binlog_row_based is initialized for the ndb_binlog
thread's THD object when the THD object is created. So we're
not going to read uninitialized memory.
- The behavior of ndb_binlog thread does not use the state of the
current_stmt_binlog_row_based. It is conceivable that the
ndb_binlog thread would rely on the current_stmt_binlog_format
in two situations:
(1) when it calls mysql_parse;
(2) when it calls THD::binlog_query.
In case (1), it always clears THD::options&OPTION_BIN_LOG (because
run_query() in ha_ndbcluster_binlog.cc is only called with
disable_binlogging = TRUE).
In case (2), it always uses qtype=STMT_QUERY_TYPE.
sql/set_var.cc:
Added @todo comment for post-push cleanup.
sql/share/errmsg.txt:
Added new error messages and clarified ER_BINLOG_UNSAFE_STATEMENT.
sql/sp.cc:
Added DBUG_ENTER, to be able to trace when set_stmt_unsafe is called.
Got rid of MYSQL_QUERY_TYPE: it was equivalent to STMT_QUERY_TYPE.
sql/sp_head.cc:
Use member function to read current_stmt_binlog_row_based.
sql/sp_head.h:
Added DBUG_ENTER, to be able to trace when set_stmt_unsafe is called.
sql/sql_acl.cc:
Got rid of MYSQL_QUERY_TYPE: it was equivalent to STMT_QUERY_TYPE.
sql/sql_base.cc:
- Made decide_logging_format take care of all logic for deciding the
logging format, and for determining the related warnings and errors.
See comment above decide_logging_format for details.
- Made decide_logging_format a member function of THD, since it needs
to access private members of THD and since its purpose is to update
the state of a THD object.
- Added DBUG_ENTER, to be able to trace when set_stmt_unsafe is called.
sql/sql_class.cc:
- Moved logic for determining unsafe warnings away from THD::binlog_query
(and into decide_logging_format()). Now, it works like this:
1. decide_logging_format detects that the current statement shall
produce a warning, if it ever makes it to the binlog
2. decide_logging_format sets a flag of THD::binlog_warning_flags.
3. THD::binlog_query reads the flag. If the flag is set, it generates
a warning.
- Use member function to read current_stmt_binlog_row_based.
sql/sql_class.h:
- Added THD::binlog_warning_flags (see sql_class.cc for explanation).
- Made decide_logging_format() and reset_for_next_command() member
functions of THD (instead of standalone functions). This was needed
for two reasons: (1) the functions need to access the private member
THD::binlog_warning_flags; (2) the purpose of these functions is to
update the staet of a THD object, so from an object-oriented point
of view they should be member functions.
- Encapsulated current_stmt_binlog_row_based, so it is now private and
can only be accessed from a member function. Also changed the
data type to an enumeration instead of a bool.
- Removed MYSQL_QUERY_TYPE, because it was equivalent to
STMT_QUERY_TYPE anyways.
- When reset_current_stmt_binlog_row_based was called from the
ndb_binlog thread, it would behave as a no-op. This special
case has been removed, and the behavior of
reset_current_stmt_binlog_row_based does not depend on which thread
calls it any more. The special case did not serve any purpose,
since the ndb binlog thread did not take the
current_stmt_binlog_row_based flag into account anyways.
sql/sql_delete.cc:
- Moved logic for setting row format for DELETE..LIMIT away from
mysql_prepare_delete.
(Instead, we mark the statement as unsafe at parse time (sql_yacc.yy)
and rely on decide_logging_format() (sql_class.cc) to set row format.)
This is part of the fix for BUG#45831.
- Use member function to read current_stmt_binlog_row_based.
sql/sql_insert.cc:
- Removed unnecessary calls to thd->lex->set_stmt_unsafe() and
thd->set_current_stmt_binlog_row_based_if_mixed() from
handle_delayed_insert(). The calls are unnecessary because they
have already been made; they were made in the constructor of
the `di' object.
- Since decide_logging_format() is now a member function of THD, code
that calls decide_logging_format() had to be updated.
- Added DBUG_ENTER call, to be able to trace when set_stmt_unsafe is
called.
- Moved call to set_stmt_unsafe() for INSERT..SELECT..LIMIT away from
mysql_insert_select_prepare() (and into decide_logging_format).
This is part of the fix for BUG#45831.
- Use member function to read current_stmt_binlog_row_based.
sql/sql_lex.h:
- Added the flag BINLOG_STMT_FLAG_ROW_INJECTION to enum_binlog_stmt_flag.
This was necessary so that a statement can identify itself as a row
injection.
- Added appropriate setter and getter functions for the new flag.
- Added or clarified some comments.
- Added DBUG_ENTER()
sql/sql_load.cc:
Use member function to read current_stmt_binlog_row_based.
sql/sql_parse.cc:
- Made mysql_reset_thd_for_next_command() clear thd->binlog_warning_flags.
- Since thd->binlog_warning_flags is private, it must be set in a
member function of THD. Hence, moved the body of
mysql_reset_thd_for_next_command() to the new member function
THD::reset_thd_for_next_command(), and made
mysql_reset_thd_for_next_command() call
THD::reset_thd_for_next_command().
- Removed confusing comment.
- Use member function to read current_stmt_binlog_row_based.
sql/sql_repl.cc:
Use member function to read current_stmt_binlog_row_based.
sql/sql_table.cc:
Use member function to read current_stmt_binlog_row_based.
sql/sql_udf.cc:
Use member function to read current_stmt_binlog_row_based.
sql/sql_update.cc:
Moved logic for setting row format for UPDATE..LIMIT away from
mysql_prepare_update.
(Instead, we mark the statement as unsafe at parse time (sql_yacc.yy)
and rely on decide_logging_format() (sql_class.cc) to set row format.)
This is part of the fix for BUG#45831.
sql/sql_yacc.yy:
Made INSERT DELAYED, INSERT..SELECT..LIMIT, UPDATE..LIMIT, and
DELETE..LIMIT mark themselves as unsafe at parse time (instead
of at execution time).
This is part of the fixes BUG#45831 and BUG#45825.
storage/example/ha_example.cc:
Made exampledb accept inserts. This was needed by the new test case
rpl_ndb_binlog_format_errors, because it needs an engine that
is statement-only (and accepts inserts).
storage/example/ha_example.h:
Made exampledb a statement-only engine instead of a row-only engine.
No existing test relied exampledb's row-only capabilities. The new
test case rpl_ndb_binlog_format_errors needs an engine that is
statement-only.
storage/innobase/handler/ha_innodb.cc:
- Changed error error code and message given by innodb when
binlog_format=STATEMENT and transaction isolation level is
READ COMMITTED or READ UNCOMMITTED.
- While I was here, also simplified the condition for
checking when to give the error.

Bug#26030 (Parsing fails for stored routine w/multi-statement execution
enabled) Before this fix, the lexer and parser would treat the ';' character as a different token (either ';' or END_OF_INPUT), based on convoluted logic, which failed in simple cases where a stored procedure is implemented as a single statement, and used in a multi query. With this fix: - the character ';' is always parsed as a ';' token in the lexer, - parsing multi queries is implemented in the parser, in the 'query:' rules, - the value of thd->client_capabilities, which is the capabilities negotiated between the client and the server during bootstrap, is immutable and not arbitrarily modified during parsing (which was the root cause of the bug) |

Bug#36570: Parse error of CREATE PROCEDURE stmt with comments on \
slave The stored-routine code took the contents of the (lowest) parser and copied it directly to the binlog, which causes problems if there is a special case of interpretation at the parser level -- which there is, in the "/*!VER */" comments. The trailing "*/" caused errors on the slave, naturally. Now, since by that point we have /properly/ created parse-tree (as the rest of the server should do!) for the stored-routine CREATE, we can construct a perfect statement from that information, instead of writing uncertain information from an unknown parser state. Fortunately, there's already a function nearby that does exactly that. --- Update for Bug#36570. Qualify routine names with db name when writing to the binlog ONLY if the source text is qualified. mysql-test/r/binlog_innodb.result: Offsets changed due to quoting. --- New offset to account for db-qualified names. mysql-test/r/ctype_cp932_binlog.result: Offsets changed due to quoting. --- Qualify routine names with DB. Offsets change also. mysql-test/r/mysqlbinlog.result: Case changed in result due to interpretation of data instead of literal recitation. --- Qualify procedure name with db. mysql-test/r/rpl_sp.result: Offsets changed due to quoting. Added tests. --- Qualify routine names with DB if qualified in query. Offsets change also. mysql-test/t/rpl_sp.test: Add version-limiting quotes to exercise bug#36570. Test that backtick-quoted identifiers and labels work also. --- Use different db to show qualification works. Qualify routine names with DB if qualified in query. sql/sp.cc: In create_string, we may not have a sp_name parameter yet, so instead pass the char* and length of the only member we'd get out of it. Having done that, we can use the same function to write the CREATE (FUNC|TRIG|PROC) statement to the binlog as we always used to display the statement to the user. --- Make the db name part of the CREATE string if it is specified. Specify it in part of writing to the binlog when creating a new routine. sql/sp_head.cc: Set the sp_head m_explicit_name member as the sp_name member is set. We can not peek at this later, as the sp_name is gone by then. sql/sp_head.h: Add a member to track whether the name is qualified with the database. |

Bug#33618 (Crash in sp_rcontext)
Bug 33983 (Stored Procedures: wrong end <label> syntax is accepted) The server used to crash when REPEAT or another control instruction was used in conjunction with labels and a LEAVE instruction. The crash was caused by a missing "pop" of handlers or cursors in the code representing the stored program. When executing the code in a loop, this missing "pop" would result in a stack overflow, corrupting memory. Code generation has been fixed to produce the missing h_pop/c_pop instructions. Also, the logic checking that labels at the beginning and the end of a statement are matched was incorrect, causing Bug 33983. End labels, when used, must match the label used at the beginning of a block. mysql-test/r/sp-code.result: Bug#33618 (Crash in sp_rcontext) mysql-test/r/sp-error.result: Bug 33983 (Stored Procedures: wrong end <label> syntax is accepted) mysql-test/r/sp.result: Bug#33618 (Crash in sp_rcontext) mysql-test/t/sp-code.test: Bug#33618 (Crash in sp_rcontext) mysql-test/t/sp-error.test: Bug 33983 (Stored Procedures: wrong end <label> syntax is accepted) mysql-test/t/sp.test: Bug#33618 (Crash in sp_rcontext) sql/sp_head.cc: Bug#33618 (Crash in sp_rcontext) sql/sp_head.h: Bug#33618 (Crash in sp_rcontext) sql/sp_rcontext.cc: Bug#33618 (Crash in sp_rcontext) sql/sp_rcontext.h: Bug#33618 (Crash in sp_rcontext) sql/sql_yacc.yy: Bug#33618 (Crash in sp_rcontext) |

Bug #31153 calling stored procedure crashes server if available memory is low
When the server was out of memory it crashed because of invalid memory access. This patch adds detection for failed memory allocations and make the server output a proper error message. sql/mysqld.cc: Don't try to push_warning from within push_warning. It will cause a recursion until the stack is consumed. If my_net_init fails (for example: because of OOM) the temporary vio object might have been attached to the thd object already. This will cause a double free on the vio object when the thd object is deleted later on and the server will crash. sql/sp_head.cc: Added check for out-of-memory on a 'new' operation. Refactored reset_lex method to return a error state code instead of void. Initialize the mem-root with init_sql_alloc to get a basic error handler for memory allocation problems. This alone won't prevent the server from crashing, NULL pointers have to be accounted for as well. sql/sp_head.h: Use the throw() clause in operator new, to indicate to the compiler that memory allocation can fail and return NULL, so that the compiler should generate code to check for NULL before invoking C++ constructors, to be crash safe. sql/sql_base.cc: Use init_sql_alloc to get basic out-of-memory error handling. sql/sql_lex.h: Use the throw() clause in operator new, to indicate to the compiler that memory allocation can fail and return NULL, so that the compiler should generate code to check for NULL before invoking C++ constructors, to be crash safe. sql/sql_prepare.cc: Use init_sql_alloc to get basic out-of-memory error handling. sql/sql_yacc.yy: Check for memory allocation failures where it matters. |

Bug#28318 CREATE FUNCTION (UDF) requires a schema
Bug#29816 Syntactically wrong query fails with misleading error message The core problem is that an SQL-invoked function name can be a <schema qualified routine name> that contains no <schema name>, but the mysql parser insists that all stored procedures (function, procedures and triggers) must have a <schema name>, which is not true for functions. This problem is especially visible when trying to create a function or when a query contains a syntax error after a function call (in the same query), both will fail with a "No database selected" message if the session is not attached to a particular schema, but the first one should succeed and the second fail with a "syntax error" message. Part of the fix is to revamp the sp name handling so that a schema name may be omitted for functions -- this means that the internal function name representation may not have a dot, which represents that the function doesn't have a schema name. The other part is to place schema checks after the type (function, trigger or procedure) of the routine is known. mysql-test/r/sp-error.result: Add test case result for Bug#29816 mysql-test/r/udf.result: Add test case result for Bug#28318 mysql-test/t/sp-error.test: Add test case for Bug#29816 mysql-test/t/udf.test: Add test case for Bug#28318 sql/sp.cc: Copy the (last) nul byte of the stored routine key and move name parsing code to the sp_name class constructor. sql/sp_head.cc: Revamp routine name parsing for when no schema is specified and omit dot from the qualified name if the routine is not associated with a scheme name. sql/sp_head.h: Name parsing got bigger, uninline by moving to a single unit -- the sp_head.cc file. sql/sql_yacc.yy: Only copy the schema name if one is actually set and check for schema name presence only where it's necessary. |

A fix and a test case for Bug#26141 mixing table types in trigger
causes full table lock on innodb table. Also fixes Bug#28502 Triggers that update another innodb table will block on X lock unnecessarily (duplciate). Code review fixes. Both bugs' synopses are misleading: InnoDB table is not X locked. The statements, however, cannot proceed concurrently, but this happens due to lock conflicts for tables used in triggers, not for the InnoDB table. If a user had an InnoDB table, and two triggers, AFTER UPDATE and AFTER INSERT, competing for different resources (e.g. two distinct MyISAM tables), then these two triggers would not be able to execute concurrently. Moreover, INSERTS/UPDATES of the InnoDB table would not be able to run concurrently. The problem had other side-effects (see respective bug reports). This behavior was a consequence of a shortcoming of the pre-locking algorithm, which would not distinguish between different DML operations (e.g. INSERT and DELETE) and pre-lock all the tables that are used by any trigger defined on the subject table. The idea of the fix is to extend the pre-locking algorithm to keep track, for each table, what DML operation it is used for and not load triggers that are known to never be fired. mysql-test/r/trigger-trans.result: Update results (Bug#26141) mysql-test/r/trigger.result: Update results (Bug#28502) mysql-test/t/trigger-trans.test: Add a test case for Bug#26141 mixing table types in trigger causes full table lock on innodb table. mysql-test/t/trigger.test: Add a test case for Bug#28502 Triggers that update another innodb table will block echo on X lock unnecessarily. Add more test coverage for triggers. sql/item.h: enum trg_event_type is needed in table.h sql/sp.cc: Take into account table_list->trg_event_map when determining what tables to pre-lock. After this change, if we attempt to fire a trigger for which we had not pre-locked any tables, error 'Table was not locked with LOCK TABLES' will be printed. This, however, should never happen, provided the pre-locking algorithm has no programming bugs. Previously a trigger key in the sroutines hash was based on the name of the table the trigger belongs to. This was possible because we would always add to the pre-locking list all the triggers defined for a table when handling this table. Now the key is based on the name of the trigger, owing to the fact that a trigger name must be unique in the database it belongs to. sql/sp_head.cc: Generate sroutines hash key in init_spname(). This is a convenient place since there we have all the necessary information and can avoid an extra alloc. Maintain and merge trg_event_map when adding and merging elements of the pre-locking list. sql/sp_head.h: Add ,m_sroutines_key member, used when inserting the sphead for a trigger into the cache of routines used by a statement. Previously the key was based on the table name the trigger belonged to, since for a given table we would add to the sroutines list all the triggers defined on it. sql/sql_lex.cc: Introduce a new lex step: set_trg_event_type_for_tables(). It is called when we have finished parsing but before opening and locking tables. Now this step is used to evaluate for each TABLE_LIST instance which INSERT/UPDATE/DELETE operation, if any, it is used in. In future this method could be extended to aggregate other information that is hard to aggregate during parsing. sql/sql_lex.h: Add declaration for set_trg_event_type_for_tables(). sql/sql_parse.cc: Call set_trg_event_type_for_tables() after MYSQLparse(). Remove tabs. sql/sql_prepare.cc: Call set_trg_event_type_for_tables() after MYSQLparse(). sql/sql_trigger.cc: Call set_trg_event_type_for_tables() after MYSQLparse(). sql/sql_trigger.h: Remove an obsolete member. sql/sql_view.cc: Call set_trg_event_type_for_tables() after MYSQLparse(). sql/sql_yacc.yy: Move assignment of sp_head::m_type before calling sp_head::init_spname(), one is now used inside another. sql/table.cc: Implement TABLE_LIST::set_trg_event_map() - a method that calculates wh triggers may be fired on this table when executing a statement. sql/table.h: Add missing declarations. Move declaration of trg_event_type from item.h (it will be needed for trg_event_map bitmap when we start using Bitmap template instead of uint8). |

Patch for the following bugs:
- BUG#11986: Stored routines and triggers can fail if the code
has a non-ascii symbol
- BUG#16291: mysqldump corrupts string-constants with non-ascii-chars
- BUG#19443: INFORMATION_SCHEMA does not support charsets properly
- BUG#21249: Character set of SP-var can be ignored
- BUG#25212: Character set of string constant is ignored (stored routines)
- BUG#25221: Character set of string constant is ignored (triggers)
There were a few general problems that caused these bugs:
1. Character set information of the original (definition) query for views,
triggers, stored routines and events was lost.
2. mysqldump output query in client character set, which can be
inappropriate to encode definition-query.
3. INFORMATION_SCHEMA used strings with mixed encodings to display object
definition;
1. No query-definition-character set.
In order to compile query into execution code, some extra data (such as
environment variables or the database character set) is used. The problem
here was that this context was not preserved. So, on the next load it can
differ from the original one, thus the result will be different.
The context contains the following data:
- client character set;
- connection collation (character set and collation);
- collation of the owner database;
The fix is to store this context and use it each time we parse (compile)
and execute the object (stored routine, trigger, ...).
2. Wrong mysqldump-output.
The original query can contain several encodings (by means of character set
introducers). The problem here was that we tried to convert original query
to the mysqldump-client character set.
Moreover, we stored queries in different character sets for different
objects (views, for one, used UTF8, triggers used original character set).
The solution is
- to store definition queries in the original character set;
- to change SHOW CREATE statement to output definition query in the
binary character set (i.e. without any conversion);
- introduce SHOW CREATE TRIGGER statement;
- to dump special statements to switch the context to the original one
before dumping and restore it afterwards.
Note, in order to preserve the database collation at the creation time,
additional ALTER DATABASE might be used (to temporary switch the database
collation back to the original value). In this case, ALTER DATABASE
privilege will be required. This is a backward-incompatible change.
3. INFORMATION_SCHEMA showed non-UTF8 strings
The fix is to generate UTF8-query during the parsing, store it in the object
and show it in the INFORMATION_SCHEMA.
Basically, the idea is to create a copy of the original query convert it to
UTF8. Character set introducers are removed and all text literals are
converted to UTF8.
This UTF8 query is intended to provide user-readable output. It must not be
used to recreate the object. Specialized SHOW CREATE statements should be
used for this.
The reason for this limitation is the following: the original query can
contain symbols from several character sets (by means of character set
introducers).
Example:
- original query:
CREATE VIEW v1 AS SELECT _cp1251 'Hello' AS c1;
- UTF8 query (for INFORMATION_SCHEMA):
CREATE VIEW v1 AS SELECT 'Hello' AS c1;
