Most of the groundwork for sprint task 729 (implement FUNCTIONs).
Expanded the mysql.proc table, reworked the find/create/drop functions
completely, added new functions for FUNCTIONs (lotta functions here :),

the parser correspondingly, and fiddled around a bit to make SP FUNCTIONs
coexist with UDFs.

sp_head *

Better approach for prelocking of tables for stored routines execution
and some SP-related cleanups.
- We don't have separate stage for calculation of list of tables
to be prelocked and doing implicit LOCK/UNLOCK any more.
Instead we calculate this list at open_tables() and do implicit
LOCK in lock_tables() (and UNLOCK in close_thread_tables()).
Also now we support cases when same table (with same alias) is
used several times in the same query in SP.
- Cleaned up execution of SP. Moved all common code which handles
LEX and does preparations before statement execution or complex
expression evaluation to auxilary sp_lex_keeper class. Now
all statements in SP (and corresponding instructions) that
evaluate expression which can contain subquery have their
own LEX.
mysql-test/r/lock.result:
Replaced wrong error code with the correct one after fixing bug in
SP-locking.
mysql-test/r/mysqldump.result:
Added dropping of view which is used in test to its beginning.
mysql-test/r/sp.result:
Added tests for improved SP-locking.
Temporarily disabled tests for SHOW PROCEDURE STATUS and alike
(Until Monty will allow to open mysql.proc under LOCK TABLES without
mentioning it in lock list).
Replaced wrong results of test for bug #5240 with correct results after
fixing bug in handling of cursors.
mysql-test/t/lock.test:
Replaced wrong error code with the correct one after fixing bug in
SP-locking.
mysql-test/t/mysqldump.test:
Added dropping of view which is used in test to its beginning.
mysql-test/t/sp.test:
Added tests for improved SP-locking.
Temporarily disabled tests for SHOW PROCEDURE STATUS and alike
(Until Monty will allow to open mysql.proc under LOCK TABLES without
mentioning it in lock list).
Removed test for bug #1654 since we already test exactly this function
in one of SP-locking tests.
Removed comment about cursor's wrong behavior in test for bug #5240
after fixing bug which was its cause.
sql/item_func.cc:
Removed comment which is no longer true.
sql/mysql_priv.h:
Changed open_tables() signature.
Now its 2nd parameter is in/out since it can add elements to table list.
sql/sp.cc:
sp_find_procedure():
Added one more parameter which enforces cache only lookup.
sp_merge_hash():
Now uses its return value to indicate that first of two hashes changed
as result of merge.
sp_cache_routines():
This function caches all stored routines used in query now.
sql/sp.h:
- sp_find_procedure() now has one more parameter which enforces cache only
lookup.
- sp_merge_hash() now uses its return value to indicate that first of two
hashes changed as result of merge.
- sp_cache_routines() caches all stored routines now. So it does not need
third argument any more.
sql/sp_head.cc:
sp_head::sp_head():
Added initialization of new m_spfuns and m_spprocs members.
sp_head::execute():
Let us save/restore part of thread context which can be damaged by
execution of instructions.
sp_head::execute_function()/execute_procedure():
Now it is responsibility of caller to close tables used in
subqueries which are passed as routine parameters.
sp_head::restore_lex():
Let us accumulate information about routines used by this one
in new m_spfuns, m_spprocs hashes.
sp_lex_keeper::reset_lex_and_exec_core()
Main method of new auxilary sp_lex_keeper class to which instructions
delegate responsibility for handling LEX and preparations before
executing statement or calculating complex expression.
Since all instructions which calculate complex expression or execute
command now use sp_lex_keeper they have to implement
sp_instr::exec_core() method. Most of instruction specific logic
has moved from sp_instr::execute() to this new method.
Removed sp_instr_set_user_var class which is no longer used, because
nowdays we allow execution of statements in stored functions and
triggers.
sp_merge_table_list() became sp_head::merge_table_list() method. It
also treats sp_head::m_sptabs as multi-set of tables now.
sp_hash_to_table_list() became sp_head::add_used_tables_to_table_list().
It takes into account that sp_head::m_sptabs is multi-set and allocates
object into persistent arena of PS.
Removed sp_merge_table_hash(), sp_open_and_lock_tables(),
sp_unlock_tables(), sp_merge_routine_tables() methods since they are not
used by new prelocking mechanism.
Added sp_add_sp_tables_to_table_list() which serves for adding tables needed
by routines used in query to the query table list for prelocking.
sql/sp_head.h:
class sp_head:
- Added m_spfuns, m_spprocs members for storing names of routines used
by this routine.
- Added add_used_tables_to_table_list() method which allows to add
tables needed by this routine to query's table list.
- Converted sp_merge_table_list() to sp_head::merge_table_list() method.
- Changed semantics of THD::m_sptabs. Now it is multi-set which contains
only tables which are used by this routine and not routines that are
called from this one.
Removed sp_merge_routine_tables(), sp_merge_table_hash(),
sp_open_and_lock_tables(), sp_unlock_tables() calls since they are not
used for our prelocking list calculation.
Added auxilary sp_lex_keeper class to which instructions delegate
responsibility for handling LEX and preparations before executing
statement or calculating complex expression. This class uses
new sp_instr::exec_core() method which is responsible for executing
instruction's core function after all preparations were made.
All instructions which hold and calculate complex expression now have
their own LEX (by aggregating sp_lex_keeper instance). sp_instr_stmt
now uses sp_lex_keeper too.
Removed sp_instr_set_user_var class which is no longer used, because
nowdays we allow execution of statements in stored functions and
triggers.
sql/sp_rcontext.cc:
Now sp_cursor holds pointer to sp_lex_keeper instead of LEX.
sql/sp_rcontext.h:
Now sp_cursor holds pointer to sp_lex_keeper instead of LEX.
sql/sql_acl.cc:
acl_init(), grant_init():
Now we use simple_open_n_lock_tables() instead of explicit
calls to open_tables() and mysql_lock_tables().
sql/sql_base.cc:
Implemented support for execution of statements in "prelocked" mode.
When we have statement which uses stored routines explicitly or
implicitly (via views or triggers) we have to open and lock all tables
for these routines at the same time as tables for the main statement.
In fact we have to do implicit LOCK TABLES at the begining of such
statement and implict UNLOCK TABLES at its end. We call such mode
"prelocked".
When open_tables() is called for the statement tables which are needed
for execution of routines used by it are added to its tables list
(this process also caches all routines used). Implicit use of routines
is discovered when we open view or table with trigger and apropriate
tables are added to the table list at this moment. Statement which has
such extra tables in its list (well actually any that uses functions)
is marked as requiring prelocked mode for its execution.
When lock_tables() sees such statement it will issue implicit LOCK TABLES
for this extended table list instead of doing usual locking, it will also
set THD::prelocked_mode to indicate that we are in prelocked mode.
When open_tables()/lock_tables() are called for statement of stored
routine (substatement), they notice that we are running in prelocked mode
and use one of prelocked tables from those that are not used by upper
levels of execution.
close_thread_tables() for substatement won't really close tables used
but will mark them as free for reuse instead.
Finally when close_thread_tables() is called for the main statement it
really unlocks and closes all tables used.
Everything will work even if one uses such statement under real LOCK
TABLES (we are simply not doing implicit LOCK/UNLOCK in this case).
sql/sql_class.cc:
Added initialization of THD::prelocked_mode member.
sql/sql_class.h:
- Added prelocked_mode_type enum and THD::prelocked_mode member
which are used for indication whenever "prelocked mode" is on
(i.e. that statement uses stored routines and is executed under
implicit LOCK TABLES).
- Removed THD::shortcut_make_view which is no longer needed.
We use TABLE_LIST::prelocking_placeholder for the same purprose
now.
sql/sql_handler.cc:
Changed open_tables() invocation.
Now its 2nd parameter is in/out since it can add elements to table list.
sql/sql_lex.cc:
lex_start():
Added initialization of LEX::query_tables_own_last.
Unused LEX::sptabs member was removed.
st_lex::unlink_first_table()/link_first_table_back():
We should update LEX::query_tables_last properly if table list
contains(ed) only one element.
sql/sql_lex.h:
LEX:
- Removed sptabs member since it is no longer used.
- Added query_tables_own_last member, which if non-0 indicates that
statement requires prelocking (implicit LOCK TABLES) for its execution
and points to last own element in query table list. If it is zero
then this query does not need prelocking.
- Added requires_prelocking(), mark_as_requiring_prelocking(),
first_not_own_table() inline methods to incapsulate and simplify
usage of this new member.
sql/sql_parse.cc:
dispatch_command():
To properly leave prelocked mode when needed we should call
close_thread_tables() even if there are no open tables.
mysql_execute_command():
- Removed part of function which were responsible for doing implicit
LOCK TABLES before statement execution if statement used stored
routines (and doing UNLOCK TABLES at the end).
Now we do all this in open_tables()/lock_tables()/close_thread_tables()
instead.
- It is also sensible to reset errors before execution of statement
which uses routines.
- SQLCOM_DO, SQLCOM_SET_OPTION, SQLCOM_CALL
We should always try to open tables because even if statement has empty
table list, it can call routines using tables, which should be preopened
before statement execution.
- SQLCOM_CALL
We should not look up routine called in mysql.proc, since it should be
already cached by this moment by open_tables() call.
- SQLCOM_LOCK_TABLES
it is better to use simple_open_n_lock_tables() since we want to avoid
materialization of derived tables for this command.
sql/sql_prepare.cc:
mysql_test_update():
Changed open_tables() invocations. Now its 2nd parameter is in/out
since it can add elements to table list.
check_prepared_statement():
Since now we cache all routines used by statement in open_tables() we
don't need to do it explicitly.
mysql_stmt_prepare():
Now we should call close_thread_tables() when THD::lex points to the
LEX of statement which opened tables.
reset_stmt_for_execute():
Commented why we are resetting all tables in table list.
sql/sql_trigger.h:
Table_triggers_list::process_triggers():
We should surpress sending of ok packet when we are calling trigger's
routine, since now we allow statements in them.
sql/sql_update.cc:
Changed open_tables() invocations.
Now its 2nd parameter is in/out since it can add elements to table list.
sql/sql_view.cc:
mysql_make_view():
- Removed handling of routines used in view. Instead we add tables which
are needed for their execution to statement's table list in
open_tables().
- Now we use TABLE_LIST::prelocking_placeholder instead of
THD::shortcut_make_view for indicating that view is opened
only to discover which tables and routines it uses (this happens
when we build extended table list for prelocking). Also now we try
to avoid to modify main LEX in this case (except of its table list).
- Corrected small error we added tables to the table list of the main
LEX without updating its query_tables_last member properly.
sql/sql_yacc.yy:
Now each expression which is used in SP statements and can contain
subquery has its own LEX. This LEX is stored in corresponding sp_instr
object and used along with Item tree for expression calculation.
We don't need sp_instr_set_user_var() anymore since now we allow
execution of statements in stored functions and triggers.
sql/table.h:
Added TABLE_LIST::prelocking_placeholder member for distinguishing
elements of table list which does not belong to the statement itself
and added there only for prelocking (as they are to be used by routines
called by this statement).
sql/tztime.cc:
my_tz_init():
Now we use more simplier simple_open_n_lock_tables() call instead of
open_tables()/lock_tables() pair.

In order to make ALTER PROCEDURE|FUNCTION work correctly, and in general to
make characteristics (and SHOW) work right, we had to separate the old
definition blob in the mysql.proc table into separate fields for parameters,
return type, and body, and handle the characteristics (like SQL SECURITY)
separately... and then reassemble the CREATE string for parsing, of course.
This is rather ugly, mostly the parser bit. (Hopefully that will be better
with the new parser.)

Separated the definitions string of the procedure into different columns
in the mysql.proc schema.

Rewrote much of the code related this (have a assemble the definition
string from its different parts now) and the way characteristics are now
handled, in order to make ALTER actually work.
sql/sp.h:
Changed prototypes.

return type (for functions) and body.
sql/sql_yacc.yy:

This is ugly and messy; hopefully there's a more elegant way to do this
when the new parser is installed.

WL#2130: Table locking for stored FUNCTIONs
Collect all tables and SPs refered by a statement, and open all tables
with an implicit LOCK TABLES. Do find things refered by triggers and views,
we open them first (and then repeat this until nothing new is found), before
doing the actual lock tables.
mysql-test/r/information_schema.result:

mysql-test/r/sp-error.result:

mysql-test/t/information_schema.test:
Disabled one test case due to a bug involving LOCK TABLES,
which shows up with WL#2130.
mysql-test/t/lock.test:
New error message with WL#2130. This change is under debate and might change
in the future, but will do for now.
mysql-test/t/sp-error.test:
Updated for WL#2130. Some tests are voided when table access does work from
functions.
mysql-test/t/sp.test:
Updated for WL#2130.
mysql-test/t/view.test:
Updated for WL#2130.
sql/item_func.cc:
We now have to set net.no_send_ok for functions too, with WL#2130.
sql/share/errmsg.txt:
Reused an error code since the old use was voided by WL#2130, but a new
one was needed instead (similar, but more specific restriction).
sql/sp.cc:
Fixed error handling and collection of used tables for WL#2130.
sql/sp.h:
Fixed error handling and collection of used tables for WL#2130.
sql/sp_head.cc:
Added support functions for collecting and merging hash tables and lists

sql/sp_head.h:
Added support functions for collecting and merging hash tables and lists
of used tables from SPs and substatements, for WL#2130.
sql/sql_base.cc:
Changed the way table->query_id is tested and set during with locked tables
in effect. This makes some SP test cases work with WL#2130, but has a side
effect on some error cases with explicit LOCK TABLES. It's still debated if
this is the correct way, so it might change.
sql/sql_class.h:
Added flags for circumventing some interference between WL#2130 and mysql_make_view().
sql/sql_derived.cc:
Added some missing initializations. (Potential bugs.)
sql/sql_lex.cc:
Clear the new hash tables for WL#2130.

Added hash tables for procedures and tables too (as for functions), for WL#2130.
sql/sql_parse.cc:
WL#2130: Make table accesses from stored functions work by adding an implicit
LOCK TABLES around (most) executed statements. To do this, we have to go through
a loop where we collect all SPs and tables in mysql_execute_statement.
sql/sql_prepare.cc:
Cache both functions and procedures for WL#2130.
sql/sql_show.cc:
Added some missing initializations. (Potential bugs.)
sql/sql_view.cc:
Shortcut mysql_make_view() if thd->shortcut_make_view is true during
the pre-open phase for collecting tables in WL#2130. Otherwise, the
similar mechanism here causes interference.
sql/sql_yacc.yy:
For WL#2130, added caching of procedures and disallowed LOCK/UNLOCK TABLES in SPs.

In order to make ALTER PROCEDURE|FUNCTION work correctly, and in general to
make characteristics (and SHOW) work right, we had to separate the old
definition blob in the mysql.proc table into separate fields for parameters,
return type, and body, and handle the characteristics (like SQL SECURITY)
separately... and then reassemble the CREATE string for parsing, of course.
This is rather ugly, mostly the parser bit. (Hopefully that will be better
with the new parser.)
Docs/sp-imp-spec.txt:
Separated the definitions string of the procedure into different columns
in the mysql.proc schema.
mysql-test/r/sp.result:
New characteristics tests.
mysql-test/t/sp.test:
New characteristics tests.
scripts/mysql_create_system_tables.sh:
Separated the definitions string of the procedure into different columns
in the mysql.proc schema.
scripts/mysql_fix_privilege_tables.sql:
Separated the definitions string of the procedure into different columns
in the mysql.proc schema.
sql/sp.cc:
Separated the definitions string of the procedure into different columns.
Rewrote much of the code related this (have a assemble the definition
string from its different parts now) and the way characteristics are now
handled, in order to make ALTER actually work.
sql/sp.h:
Changed prototypes.
sql/sp_head.cc:
Rewrote much of the code related to the new mysql.proc schema with separate
definition fields (have to assemble the definition string from its different
parts now) and the way characteristics are now handled, in order to make ALTER
actually work.
sql/sp_head.h:
Separated the different parts of the definition strings: name, parameters,
return type (for functions) and body.
sql/sql_yacc.yy:
Separated the different parts of the definition strings: name, parameters,
return type (for functions) and body.
This is ugly and messy; hopefully there's a more elegant way to do this
when the new parser is installed.
