cursor is interpreted latin1 character and Bug#9819 "Cursors: Mysql Server
Crash while fetching from table with 5 million records."
A fix for a possible memory leak when fetching into an SP cursor
in a long loop.
The patch uses a common implementation of cursors in the binary protocol and
in stored procedures and implements materialized cursors.
For implementation details, see comments in sql_cursor.cc
include/my_sys.h:
- declaration for multi_alloc_root
libmysqld/Makefile.am:
- drop protocol_cursor.cc, add sql_cursor.cc (replaces the old
implementation of cursors with a new one)
mysql-test/r/ctype_ujis.result:
- test results fixed (a test case for Bug#6513)
mysql-test/r/sp-big.result:
- test results fixed (a test case for Bug#9819)
mysql-test/t/ctype_ujis.test:
Add a test case for Bug#6513 "Test Suite: Values inserted by using cursor is
interpreted latin1 character"
mysql-test/t/sp-big.test:
Add a restricted test case for Bug#9819 "Cursors: Mysql Server Crash
while fetching from table with 5 million records."
mysys/my_alloc.c:
- an implementation of multi_alloc_root; this is largely a copy-paste
from mulalloc.c, but the function is small and there is no easy way
to reuse the existing C function.
sql/Makefile.am:
- add sql_cursor.h, sql_cursor.cc (a new implementation of stored procedure
cursors) and drop protocol_cursor.cc (the old one)
sql/handler.cc:
- now TABLE object has its mem_root always initialized.
Adjust the implementation handler::ha_open
sql/item_subselect.cc:
- adjust to the changed declaration of st_select_lex_unit::prepare
sql/protocol.h:
- drop Protocol_cursor
sql/sp_head.cc:
- move juggling with Query_arena::free_list and Item::next to
sp_eval_func_item, as this is needed in 3 places already.
sql/sp_head.h:
- declare a no-op implementation for cleanup_stmt in sp_instr_cpush.
This method is needed for non-materializing cursors, which are yet not
used in stored procedures.
- declaration for sp_eval_func_item
sql/sp_rcontext.cc:
- reimplement sp_cursor using the new implementation of server side cursors.
- use sp_eval_func_item to assign values of SP variables from the
row fetched from a cursor. This should fix a possible memory leak in
the old implementation of sp_cursor::fetch
sql/sp_rcontext.h:
- reimplement sp_cursor using the new implementation of server side cursors.
sql/sql_class.cc:
- disable the functionality that closes transient cursors at commit/rollback;
transient cursors are not used in 5.0, instead we use materialized ones.
To be enabled in a later version.
sql/sql_class.h:
- adjust to the rename Cursor -> Server_side_cursor
- additional declarations of select_union used in materialized cursors
sql/sql_derived.cc:
- reuse bits of tmp table code in UNION, derived tables, and materialized
cursors
- cleanup comments
sql/sql_lex.h:
- declarations of auxiliary methods used by materialized cursors
- a cleanup in st_select_lex_unit interface
sql/sql_list.h:
- add an array operator new[] to class Sql_alloc
sql/sql_prepare.cc:
- split the tight coupling of cursors and prepared statements to reuse
the same implementation in stored procedures
- cleanups of error processing in Prepared_statement::{prepare,execute}
sql/sql_select.cc:
- move the implementation of sensitive (non-materializing) cursors to
sql_cursor.cc
- make temporary tables self-contained: the table, its record and fields
are allocated in TABLE::mem_root. This implementation is not clean
and resets thd->mem_root several times because of the way create_tmp_table
works (many additional things are done inside it).
- adjust to the changed declaration of st_select_lex_unit::prepare
sql/sql_select.h:
- move the declaration of sensitive (non-materializing) cursors to
sql_cursor.cc
sql/sql_union.cc:
- move pieces of st_select_unit::prepare to select_union and st_table
methods to be able to reuse code in the implementation of materialized
cursors
sql/sql_view.cc:
- adjust to the changed signature of st_select_lex_unit::prepare
sql/table.cc:
- implement auxiliary st_table methods for use with temporary tables
sql/table.h:
- add declarations for auxiliary methods of st_table used to work with
temporary tables
tests/mysql_client_test.c:
- if cursors are materialized, a parallel update of the table used
in the cursor may go through: update the test.
sql/sql_cursor.cc:
New BitKeeper file ``sql/sql_cursor.cc'' -- implementation of server side
cursors
sql/sql_cursor.h:
New BitKeeper file ``sql/sql_cursor.h'' - declarations for
server side cursors.
thd->allow_sum_func was left 'true' after previous statement thus allowing
sum funcs to be present in conditions.
thd->allow_sum_func should be set to 0 for each query and each prepared
statement reinitialization. This is done in lex_start() and
reset_stmt_for_execute().
sql/sql_lex.cc:
Fix bug#13180 thd->allow_sum_func wasn't reset obefore query processing.
thd->allow_sum_func is set to 0 in lex_start().
sql/sql_prepare.cc:
Fix bug#13180 thd->allow_sum_func wasn't reset obefore query processing.
thd->allow_sum_func is set to 0 in reset_stmt_for_execute().
mysql-test/t/update.test:
Test case for bug#13180 thd->allow_sum_funcs wasn't reset before query
processing.
mysql-test/r/update.result:
Test case for bug#13180 thd->allow_sum_funcs wasn't reset before query
processing.

This bug occurs when some trigger for table used by DML statement is created
or changed while statement was waiting in lock_tables(). In this situation
prelocking set which we have calculated becames invalid which can easily lead
to errors and even in some cases to crashes.
With proposed patch we no longer silently reopen tables in lock_tables(),
instead caller of lock_tables() becomes responsible for reopening tables and
recalculation of prelocking set.
mysql-test/t/trigger.test:
Added tests for bug #12704 "Server crashes during trigger execution".
Unfortunately these tests rely on the order in which tables are locked
by statement so they are non-determenistic and therefore should be disabled.
sql/lock.cc:
mysql_lock_tables():
Now instead of always reopening altered or dropped tables by itself
mysql_lock_tables() can notify upper level and rely on caller doing this.
sql/mysql_priv.h:
Now mysql_lock_tables() can either reopen deleted or altered tables by itself
or notify caller about such situation through 'need_reopen' argument and rely
on it in this.
Also lock_tables() has new 'need_reopen' out parameter through which it
notifies caller that some tables were altered or dropped so he needs to reopen
them (and rebuild prelocking set some triggers may change or simply appear).
sql/sp.cc:
sp_add_used_routine():
To be able to restore LEX::sroutines_list to its state right after parsing
we now adjust LEX::sroutines_list_own_last/sroutines_list_own_elements when
we add directly used routine.
sp_remove_not_own_routines():
Added procedure for restoring LEX::sroutines/sroutines_list to their state
right after parsing (by throwing out non-directly used routines).
sp_cache_routines_and_add_tables_for_view()/sp_update_stmt_used_routines():
We should use LEX::sroutines_list instead of LEX::sroutines as source of
routines used by view, since LEX::sroutines is not availiable for view
on second attempt to open it (see comment in open_tables() about it).
sql/sp.h:
sp_remove_not_own_routines():
Added procedure for restoring LEX::sroutines/sroutines_list to their state
right after parsing (by throwing out non-directly used routines).
sql/sp_head.cc:
Removed assert which is no longer always true.
sql/sql_base.cc:
reopen_table():
When we re-open table and do shallow copy of TABLE object we should adjust
pointers to it in associated Table_triggers_list object. Removed nil
operation.
open_tables():
Now this function is able to rebuild prelocking set for statement if it is
needed. It also correctly handles FLUSH TABLES which may occur during its
execution.
lock_tables():
Instead of allowing mysql_lock_tables() to silently reopen altered or dropped
tables let us notify caller and rely on that it will do reopen itself.
This solves the problem when trigger suddenly appears or changed during
mysq_lock_tables().
close_tables_for_reopen():
Added routine for properly preparing for reopening of tables and recalculation
of set of prelocked tables.
sql/sql_handler.cc:
Here we let mysql_lock_tables() to reopen dropped or altered tables by itself.
sql/sql_insert.cc:
Here we let mysql_lock_tables() to reopen dropped or altered tables by itself.
sql/sql_lex.cc:
LEX:
Added 'sroutines_list_own_last' and 'sroutines_list_own_elements' members
which are used for keeping state in which 'sroutines_list' was right after
statement parsing (and for restoring of this list to this state).
sql/sql_lex.h:
LEX:
Added 'sroutines_list_own_last' and 'sroutines_list_own_elements' members
which are used for keeping state in which 'sroutines_list' was right after
statement parsing (and for restoring of this list to this state).
Added chop_off_not_own_tables() method to simplify throwing away list
of implicitly used (prelocked) tables.
sql/sql_prepare.cc:
Now instead of silently reopening altered or dropped tables in
lock_tables() we notify caller and rely on that the caller will
reopen tables.
sql/sql_table.cc:
Here we let mysql_lock_tables() to reopen dropped or altered tables by itself.
sql/sql_trigger.cc:
Added Table_triggers_list::set_table() method to adjust Table_triggers_list
to new pointer to TABLE instance.
sql/sql_trigger.h:
Added Table_triggers_list::set_table() method to adjust Table_triggers_list
to new pointer to TABLE instance.
sql/sql_update.cc:
Now instead of silently reopening altered or dropped tables in
lock_tables() we notify caller and rely on that the caller will
reopen tables.

Information_schema DB
Bug#9846 Inappropriate error displayed while
dropping table from 'INFORMATION_SCHEMA'
Bug#10734 Grant of privileges other than 'select' and
'create view' should fail on schema
Bug#10708 SP's can use INFORMATION_SCHEMA as ROUTINE_SCHEMA
cumulative fix for bugs above(after review, 2nd version)
added privilege check for information schema db & tables
The idea of the patch is to separate statement processing logic,
such as parsing, validation of the parsed tree, execution and cleanup,
from global query processing logic, such as logging, resetting
priorities of a thread, resetting stored procedure cache, resetting
thread count of errors and warnings.
This makes PREPARE and EXECUTE behave similarly to the rest of SQL
statements and allows their use in stored procedures.
This patch contains a change in behaviour:
until recently for each SQL prepared statement command, 2 queries
were written to the general log, e.g.
[Query] prepare stmt from @stmt_text;
[Prepare] select * from t1 <-- contents of @stmt_text
The chagne was necessary to prevent [Prepare] commands from being written
to the general log when executing a stored procedure with Dynamic SQL.
We should consider whether the old behavior is preferrable and probably
restore it.
This patch refixes Bug#7115, Bug#10975 (partially), Bug#10605 (various bugs
in Dynamic SQL reported before it was disabled).
mysql-test/r/not_embedded_server.result:
Since we don't want to log Dynamic SQL in stored procedures,
now the general log gets only one log entry per SQL statement.
mysql-test/r/sp-error.result:
- remove obsolete tests
- a better error message for the case when a stored procedure that
returns a result set is called from a function
mysql-test/r/trigger.result:
- a better error message for the case when a stored procedure that
returns a result set is called from a trigger
mysql-test/t/sp-error.test:
- a better error message for the case when a stored procedure that
returns a result set is called from a function.
- move the comment to its place (end of file).
mysql-test/t/trigger.test:
- a better error message for the case when a stored procedure that
returns a result set is called from a trigger
sql/item_func.cc:
- we need to pass sql_command explicitly to get_var_with_binlog, because
when creating a query for SQL prepared statement thd->lex->sql_command
points at SQLCOM_EXECUTE, which is not listed in the list of update
queries.
sql/log_event.h:
- remove an extra copy of the previous sentence
sql/mysql_priv.h:
- fix declarations of sql_prepare.cc API
sql/share/errmsg.txt:
- a new error message, when one attempts to execute a prepared statement
which is currently being executed (this can happen only in Dynamic SQL
at the moment).
sql/sp_head.cc:
- extend sp_multi_results_command to return different flags for a
command (and rename it)
- add support for SQLCOM_PREPARE,SQLCOM_EXECUTE, SQLCOM_DEALLOCATE
to sp_get_flags_for_command
- replace multiple boolean sp_head members with uint m_flags
- a fix for a crash when user variables are used in a stored procedure
and binlog is on. A temporary fix for Bug#12637 "SP crashes the server
if it has update query with user var & binlog is enabled", which actually
stands for stored functions: now instead of a crash we break
replication if a user variable is used in a stored function which
is executed in prelocked mode.
sql/sp_head.h:
- replace multiple boolean flags of sp_head with uint m_flags;
- add flag CONTAINS_DYNAMIC_SQL
- use this flag to error if a stored procedure with Dynamic SQL is
called from a function or trigger.
sql/sql_class.cc:
- Statement_map::insert should not delete a statement if it exists,
now it's done externally to be able to handle the case when the
statement being deleted is in use.
- remove extra code (free_list is already reset in free_items)
sql/sql_lex.cc:
- add lex->stmt_prepare_mode; we can't rely on thd->command any more,
because we don't reset it any more (Dynamic SQL requirement is that
PS are as little intrusive as possible).
sql/sql_lex.h:
- declare bool LEX::stmt_prepare_mode
sql/sql_parse.cc:
- move prepared statement code to sql_prepare.cc
- change declarations (refactored code)
- better error message when one attempts to use Dynamic SQL or a
stored procedure that returns a result set in a function or trigger.
sql/sql_prepare.cc:
- major refactoring to ensure PREPARE/EXECUTE commands do not reset global THD
state and allow their use in stored procedures.
- add Prepared_statement::flags and use it to ensure no recursive execution
of a prepared statement is possible
- better comments
sql/sql_yacc.yy:
- enable PREPARE/EXECUTE/DEALLOCATE in stored procedures
- produce an error message on attempt to use PREPARE/EXECUTE/DEALLOCATE
in a stored function or trigger
mysql-test/r/sp-dynamic.result:
- sp-dynamic.test results
mysql-test/t/sp-dynamic.test:
- a new test for PREPARE/EXECUTE/DEALLOCATE in stored procedures.
- current_arena to stmt_arena: the thread may have more than one
'current' arenas: one for runtime data, and one for the parsed
tree of a statement. Only one of them is active at any moment.
- set_item_arena -> set_query_arena, because Item_arena was renamed to
Query_arena a while ago
- set_n_backup_item_arena -> set_n_backup_active_arena;
the active arena is the arena thd->mem_root and thd->free_list
are currently pointing at.
- restore_backup_item_arena -> restore_active_arena (with the same
rationale)
- change_arena_if_needed -> activate_stmt_arena_if_needed; this
method sets thd->stmt_arena active if it's not done yet.

is really needed.

To enable full access to contents of I_S tables from stored functions
or statements that use them, we manipulate with thread's open tables
state and ensure that we won't cause deadlock when we open tables by
ignoring flushes and name-locks.
Building of contents of I_S.TABLES no longer requires locking of tables
since we use use handler::info() method with HA_STATUS_AUTO flag instead
of handler::update_auto_increment() for obtaining information about
auto-increment values. But this also means that handlers have to implement
support for HA_STATUS_AUTO flag (particularly InnoDB needs it).
mysql-test/r/alter_table.result:
Updated test results. This change was caused by the fact that now when
we build contents of I_S tables (and thus output of SHOW INDEX) we
don't use instances of tables which may be already opened and locked
by thread (we always use new instance).
mysql-test/r/information_schema.result:

close_thread_tables():
Get rid of 'stopper' argument which is no longer used. Now when we need
to open and then close some table without touching tables which are already
opened we use THD::reset_n/restore_backup_open_tables_state() methods.
open_tables()/open_normal_and_derived_tables():
Added 'flags' argument to be able open tables even if some has done
a flush or hold namelock on them.
sql/sp.cc:
close_proc_table/open_proc_table_for_read/db_find_routine():
Replaced push_open_tables_state/pop_open_tables_state() methods which
were saving/restoring current open tables state in/from THD::open_state_list
with reset_n_backup_open_tables_state/restore_backup_open_tables_state()
methods which assume that backup storage for this state is allocated on
stack (or elsewhere) by their caller.
open_proc_table_for_read():
Since now we can have several open tables states stacked up we can't rely
rely on checking whether we have some tables open in previous state.
Instead we always assume that some tables are open and we need to ignore
flush while locking mysql.proc. We don't really need
MYSQL_LOCK_IGNORE_GLOBAL_READ_LOCK in this case since we open mysql.proc table
only for reading.
sql/sp.h:
Added declarations of open_proc_table_for_read()/close_proc_table() to be
able to use them in sql_show.cc.
sql/sql_base.cc:
close_thread_tables():

get_all_tables():
Now we use THD::reset_n_/restore_backup_open_tables_state() for
saving/restoring open tables state instead of working with it directly
(This also allows us to have proper content of I_S system tables in
statements with stored functions and in stored functions). We also
ignore possible flushes when opening tables (we may create deadlock
otherwise). Also we do all needed manipulations with LEX in this function
and not in get_schema_tables_result() now.
get_schema_tables_record():
Let us use handler::info() method with HA_STATUS_AUTO flag for obtaining
information about table's auto-increment value. This allows to avoid locking
of tables which is needed when we use handler::update_auto_increment() method.
fill_schema_proc():
Now we use open_proc_table_for_read/close_proc_table() for access to
mysql.proc table (so we won't cause deadlock if we already have some
tables open and locked, this also allows us to have proper content in
ROUTINES system table in statements using stored functions/in stored
functions).
get_schema_tables_result():
Moved all manipulations with Open_tables_state and LEX needed for
safe opening of tables to ST_SCHEMA_TABLE::fill_table functions
(i.e. get_all_tables() and fill_schema_proc()).
sql/sql_update.cc:
open_tables()/open_normal_and_derived_tables():
Added 'flags' argument to be able open tables even if some has done
a flush or hold namelock on them.

The idea of the patch
is that every cursor gets its own lock id for table level locking.
Thus cursors are protected from updates performed within the same
connection. Additionally a list of transient (must be closed at
commit) cursors is maintained and all transient cursors are closed
when necessary. Lastly, this patch adds support for deadlock
timeouts to TLL locking when using cursors.
+ post-review fixes.
include/thr_lock.h:
- add a notion of lock owner to table level locking. When using
cursors, lock owner can not be identified by a thread id any more,
as we must protect cursors from updates issued within the same
connection (thread). So, each cursor has its own lock identifier to
use with table level locking.
- extend return values of thr_lock and thr_multi_lock with
THR_LOCK_TIMEOUT and THR_LOCK_DEADLOCK, since these conditions
are now possible (see comments to thr_lock.c)
mysys/thr_lock.c:
Better support for cursors:
- use THR_LOCK_OWNER * as lock identifier, not pthread_t.
- check and return an error for a trivial deadlock case, when an
update statement is issued to a table locked by a cursor which has
been previously opened in the same connection.
- add support for locking timeouts: with use of cursors, trivial
deadlocks can occur. For now the only remedy is the lock wait timeout,
which is initialized from a new global variable 'table_lock_wait_timeout'
Example of a deadlock (assuming the storage engine does not downgrade
locks):
con1: open cursor for select * from t1;
con2: open cursor for select * from t2;
con1: update t2 set id=id*2; -- blocked
con2: update t1 set id=id*2; -- deadlock
Lock timeouts are active only if a connection is using cursors.
- the check in the wait_for_lock loop has been changed from
data->cond != cond to data->cond != 0. data->cond is zeroed
in every place it's changed.

- add handlerton instance, init handler::ht with it
sql/ha_myisam.h:
- ctor moved to .cc to make use of MyISAM handlerton
sql/ha_myisammrg.cc:
- init handler::ht in the ctor
sql/ha_myisammrg.h:
- ctor moved to .cc to make use of MyISAM MERGE handlerton
sql/ha_ndbcluster.cc:
- init handlerton::flags and handler::ht
sql/handler.cc:
- drop support for ISAM storage engine, which was removed from 5.0
- close all "transient" cursors at COMMIT/ROLLBACK. A "transient"
SQL level cursor is a cursor that uses tables that have a transaction-
specific state.
sql/handler.h:
- extend struct handlerton with flags, add handlerton *ht to every
handler instance.
sql/lock.cc:
- extend mysql_lock_tables to send error to the client if
thr_multi_lock returns a timeout or a deadlock error.
sql/mysqld.cc:
- add server option --table_lock_wait_timeout (in seconds)
sql/set_var.cc:
- add new global variable 'table_lock_wait_timeout' to specify
a wait timeout for table-level locks of MySQL (in seconds). The default
timeout is 50 seconds. The timeout is active only if the connection
has open cursors.
sql/sql_class.cc:
- implement Statement_map::close_transient_cursors
- safety suggests that we need an assert ensuring
llock_info->n_cursors is functioning properly, adjust destruction of
the Statement_map to allow such assert in THD::~THD
sql/sql_class.h:
- add support for Cursors registry to Statement map.
sql/sql_prepare.cc:
- maintain a list of cursors that must be closed at commit/rollback.
sql/sql_select.cc:
- extend class Cursor to support specific at-COMMIT/ROLLBACK behavior.
If a cursor uses tables of a storage engine that
invalidates all open tables at COMMIT/ROLLBACK, it must be closed
before COMMIT/ROLLBACK is executed.
sql/sql_select.h:
- add an own lock_id and commit/rollback status flag to class Cursor
tests/mysql_client_test.c:
A test case for Bug#10760 and complementary issues: test a simple
deadlock case too.

Revert wrong patch of calling close_connection() in first close_connections() loop. (Bug #7403)
Instead we now print a warning for closed connections only if mysqld is sarted with --warnings
Added comments to make the close_connections() logic clearer
sql/sql_prepare.cc:
Use floatget() and doubleget() to protect against unaligned data

Fix handling of floats and doubles when using prepared statements
API in the embedded server.
sql/sql_prepare.cc:
Jim's fix for the #10443.
Within the embedded server, there's no need to use float4get()
and float8get() for setting parameters, since they are never
stored.
in cursors.
libmysql/libmysql.c:
- reset_stmt_handle(): don't reset the server side just because we have
an open cursor: the server will close the cursor automatically if
needed
sql/sql_prepare.cc:
- implement Prepared_statement::close_cursor,
- implicitly close an open cursor in mysql_stmt_execute instead of
issuing an error (to reduce the need to explicitly close cursors
and save network bandwidth).
- cleanup
sql/sql_select.cc:
Remove a destructor: cursor destruction can not be done by simply
calling a destructor, because of cross-references between cursor
and statement memory.
sql/sql_select.h:
- add an empty Cursor destructor
tests/mysql_client_test.c:
- remove a test for dropped functionality
