Before this patch, the parser would execute:
- Select->expr_list.push_front()
- Select->expr_list.pop()
when parsing expressions lists, in the following rules:
- udf_expr_list
- expr_list
- ident_list
This is unnecessary, and introduces overhead due to the memory allocations
performed with Select->expr_list
With this patch, this code has been removed.
The list being parsed is maintained in the parser stack instead.
Also, 'udf_expr_list' has been renamed 'opt_udf_expr_list', since this
production can be empty.
sql/sql_lex.cc:
Removed unused attribute expr_list
sql/sql_lex.h:

sql/sql_yacc.yy:
Improved performances when parsing expression lists
This is a performance bug, related to the parsing or 'OR' and 'AND' boolean
expressions.
Let N be the number of expressions involved in a OR (respectively AND).
When N=1
For example, "select 1" involve only 1 term: there is no OR operator.
In 4.0 and 4.1, parsing expressions not involving OR had no overhead.
In 5.0, parsing adds some overhead, with Select->expr_list.
With this patch, the overhead introduced in 5.0 has been removed,
so that performances for N=1 should be identical to the 4.0 performances,
which are optimal (there is no code executed at all)
The overhead in 5.0 was in fact affecting significantly some operations.
For example, loading 1 Million rows into a table with INSERTs,
for a table that has 100 columns, leads to parsing 100 Millions of
expressions, which means that the overhead related to Select->expr_list
is executed 100 Million times ...
Considering that N=1 is by far the most probable expression,
this case should be optimal.
When N=2
For example, "select a OR b" involves 2 terms in the OR operator.
In 4.0 and 4.1, parsing expressions involving 2 terms created 1 Item_cond_or
node, which is the expected result.
In 5.0, parsing these expression also produced 1 node, but with some extra
overhead related to Select->expr_list : creating 1 list in Select->expr_list
and another in Item_cond::list is inefficient.
With this patch, the overhead introduced in 5.0 has been removed
so that performances for N=2 should be identical to the 4.0 performances.
Note that the memory allocation uses the new (thd->mem_root) syntax
directly.
The cost of "is_cond_or" is estimated to be neglectable: the real problem
of the performance degradation comes from unneeded memory allocations.
When N>=3
For example, "select a OR b OR c ...", which involves 3 or more terms.
In 4.0 and 4.1, the parser had no significant cost overhead, but produced
an Item tree which is difficult to evaluate / optimize during runtime.
In 5.0, the parser produces a better Item tree, using the Item_cond
constructor that accepts a list of children directly, but at an extra cost
related to Select->expr_list.
With this patch, the code is implemented to take the best of the two
implementations:
- there is no overhead with Select->expr_list
- the Item tree generated is optimized and flattened.
This is achieved by adding children nodes into the Item tree directly,
with Item_cond::add(), which avoids the need for temporary lists and memory
allocation
Note that this patch also provide an extra optimization, that the previous
code in 5.0 did not provide: expressions are flattened in the Item tree,
based on what the expression already parsed is, and not based on the order
in which rules are reduced.
For example : "(a OR b) OR c", "a OR (b OR c)" would both be represented
with 2 Item_cond_or nodes before this patch, and with 1 node only with this
patch. The logic used is based on the mathematical properties of the OR
operator (it's associative), and produces a simpler tree.

SP with local variables with non-ASCII names crashed the server.
The server replaces SP local variable names with NAME_CONST calls
when putting statements into the binary log. It used UTF8-encoded
item names as variable names for the replacement inside NAME_CONST
calls. However, statement string may be encoded by any
known character set by the SET NAMES statement.
The server used byte length of UTF8-encoded names to increment
the position in the query string that led to array index overrun.

Fixed bug #30120.
The Item_splocal class constructor has been modified to
accept new parameter `len_in_q': the byte length of
variable name in the query string.
sql/item.h:
Fixed bug #30120.
The Item_splocal class has been modified to keep new

The subst_spvars function has been modified to increment
position in the query string by the lengths of not
encoded variable names instead of byte length of names
encoded to UTF-8.

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.

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.

wh triggers may be fired on this table when executing a statement.
sql/table.h:

fails if a database is not selected prior.
The problem manifested itself when a user tried to
create a routine that had non-fully-qualified identifiers in its bodies
and there was no current database selected.
This is a regression introduced by the fix for Bug 19022:
The patch for Bug 19022 changes the code to always produce a warning
if we can't resolve the current database in the parser.
In this case this was not necessary, since even though the produced
parsed tree was incorrect, we never re-use sphead
that was obtained at first parsing of CREATE PROCEDURE.
The sphead that is anyhow used is always obtained through db_load_routine,
and there we change the current database to sphead->m_db before
calling yyparse.
The idea of the fix is to resolve the current database directly using
lex->sphead->m_db member when parsing a stored routine body, when
such is present.
This patch removes the need to reset the current database
when loading a trigger or routine definition into SP cache.
The redundant code will be removed in 5.1.

THD::copy_db_to(). The former will use the database of the sphead,
if we're parsing a stored routine, not the default database in
THD. The default database is needed to initialize tables->db
when the database part was not explicitly specified in the identifier.
sql/sql_yacc.yy:
Use st_lex::copy_db_to() in the parser, rather than
THD::copy_db_to(). The former will use the database of the sphead,
if we're parsing a stored routine, not the default database in
THD.

- 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;
client/mysqldump.c:
Set original character set and collation before dumping definition query.

on the sp->sphead pointer. If this flag is set for view DDL operations
we stop parsing with the error 'ER_SP_BAD_STATEMENT'.

Fixed runtime to no longer allow the caching of queries with UDF calls.
mysql-test/r/udf.result:
Added a test that turns on caching and checks that querys calling UDFs don't get cached.
mysql-test/t/udf.test:
Added a test that turns on caching and checks that querys calling UDFs don't get cached.
sql/sql_yacc.yy:
Fixed code to set safe_to_cache_query=0 regardless if the function call is a UDF or SP. Where it was placed previously -- at the very end of the else testing for UDFs -- it only executed the statement if the function call was a stored procedure call.
Changed code to enforce that SQL_CACHE only in the first SELECT is used to turn on caching(as documented), but any SQL_NO_CACHE will turn off caching (not documented, but a useful behaviour, especially for machine generated queries). Added test cases to explicitly test the documented caching behaviour and test cases for the reported bug.
mysql-test/r/query_cache.result:
Added non-bug specific tests that ensure that only SQL_CACHE in the first SELECT is respected when encountered by the parser. These tests validate what is already documented, that only the outer most SELECTS can use the SQL_CACHE option to turn on caching. Because it would break existing SQL applications, we do not return an error if the SQL_CACHE expression is found in nested SELECTs. Also added test to validate nested SELECT can contain SQL_NO_CACHE and it will always turn off caching for the whole query.
Also added a bug specific test case to validate that the buggy behavior as reported has been fixed.
mysql-test/t/query_cache.test:
Added non-bug specific tests that ensure that only SQL_CACHE in the first SELECT is respected when encountered by the parser. These tests validate what is already documented, that only the outer most SELECTS can use the SQL_CACHE option to turn on caching. Because it would break existing SQL applications, we do not return an error if the SQL_CACHE expression is found in nested SELECTs. Also added test to validate nested SELECT can contain SQL_NO_CACHE and it will always turn off caching for the whole query.
Also added a bug specific test case to validate that the buggy behavior as reported has been fixed.
sql/sql_yacc.yy:
Added an explicit check to make sure "SELECT SQL_CACHE" only works on the first select in a query.
The parser will always hit the outermost SELECT first, and if the SQL_CACHE option is found it sets the safe_to_query flag in the lex. Then, if there are subseqent "uncachable" subqueries or functions, as it parses those elements it sets the safe_to_query to 0. However, this cause problems if nested SELECTs also used the SQL_CACHE option, because then it would set back safe_to_query to 1, even though there are uncacheable expressions previously parsed.
By adding the check to ensure only the first SELECT can turn caching on, it means a subsequent SQL_CACHE option can't turn caching back on after a uncacheable subsequery was already encountered.

Bug 28127 (Some valid identifiers names are not parsed correctly)
Bug 26302 (MySQL server cuts off trailing "*/" from comments in SP/func)
This patch is the second part of a major cleanup, required to fix
Bug 25411 (trigger code truncated).
The root cause of the issue stems from the function skip_rear_comments,
which was a work around to remove "extra" "*/" characters from the query
text, when parsing a query and reusing the text fragments to represent a
view, trigger, function or stored procedure.
The reason for this work around is that "special comments",
like /*!50002 XXX */, were not parsed properly, so that a query like:
AAA /*!50002 BBB */ CCC
would be seen by the parser as "AAA BBB */ CCC" when the current version
is greater or equal to 5.0.2
The root cause of this stems from how special comments are parsed.
Special comments are really out-of-bound text that appear inside a query,
that affects how the parser behave.
In nature, /*!50002 XXX */ in MySQL is similar to the C concept
of preprocessing :
#if VERSION >= 50002
XXX
#endif
Depending on the current VERSION of the server, either the special comment
should be expanded or it should be ignored, but in all cases the "text" of
the query should be re-written to strip the "/*!50002" and "*/" markers,
which does not belong to the SQL language itself.
Prior to this fix, these markers would leak into :
- the storage format for VIEW,
- the storage format for FUNCTION,
- the storage format for FUNCTION parameters, in mysql.proc (param_list),
- the storage format for PROCEDURE,
- the storage format for PROCEDURE parameters, in mysql.proc (param_list),
- the storage format for TRIGGER,
- the binary log used for replication.
In all cases, not only this cause format corruption, but also provide a vector
for dormant security issues, by allowing to tunnel code that will be activated
after an upgrade.
The proper solution is to deal with special comments strictly during parsing,
when accepting a query from the outside world.
Once a query is parsed and an object is created with a persistant
representation, this object should not arbitrarily mutate after an upgrade.
In short, special comments are a useful but limited feature for MYSQLdump,
when used at an *interface* level to facilitate import/export,
but bloating the server *internal* storage format is *not* the proper way
to deal with configuration management of the user logic.
With this fix:
- the Lex_input_stream class now acts as a comment pre-processor,
and either expands or ignore special comments on the fly.
- MYSQLlex and sql_yacc.yy have been cleaned up to strictly use the
public interface of Lex_input_stream. In particular, how the input stream
accepts or rejects a character is private to Lex_input_stream, and the
internal buffer pointers of that class are strictly private, and should not
be tempered with during parsing.
This caused many changes mostly in sql_lex.cc.
During the code cleanup in case MY_LEX_NUMBER_IDENT,
Bug 28127 (Some valid identifiers names are not parsed correctly)
was found and fixed.
By parsing special comments properly, and removing the function
'skip_rear_comments' [sic],
Bug 26302 (MySQL server cuts off trailing "*/" from comments in SP/func)
has been fixed as well.

The value of "low-priority-updates" option and the LOW PRIORITY
prefix was taken into account at parse time.
This caused triggers (among others) to ignore this flag (if
supplied for the DML statement).
Moved reading of the LOW_PRIORITY flag at run time.
Fixed an incosistency when handling
SET GLOBAL LOW_PRIORITY_UPDATES : now it is in effect for
delayed INSERTs.

Bug#4968 ""Stored procedure crash if cursor opened on altered table"
Bug#6895 "Prepared Statements: ALTER TABLE DROP COLUMN does nothing"
Bug#19182 "CREATE TABLE bar (m INT) SELECT n FROM foo; doesn't work from
stored procedure."
Bug#19733 "Repeated alter, or repeated create/drop, fails"
Bug#22060 "ALTER TABLE x AUTO_INCREMENT=y in SP crashes server"
Bug#24879 "Prepared Statements: CREATE TABLE (UTF8 KEY) produces a
growing key length" (this bug is not fixed in 5.0)
Re-execution of CREATE DATABASE, CREATE TABLE and ALTER TABLE
statements in stored routines or as prepared statements caused
incorrect results (and crashes in versions prior to 5.0.25).
In 5.1 the problem occured only for CREATE DATABASE, CREATE TABLE
SELECT and CREATE TABLE with INDEX/DATA DIRECTOY options).
The problem of bugs 4968, 19733, 19282 and 6895 was that functions
mysql_prepare_table, mysql_create_table and mysql_alter_table are not
re-execution friendly: during their operation they modify contents
of LEX (members create_info, alter_info, key_list, create_list),
thus making the LEX unusable for the next execution.
In particular, these functions removed processed columns and keys from
create_list, key_list and drop_list. Search the code in sql_table.cc
for drop_it.remove() and similar patterns to find evidence.
The fix is to supply to these functions a usable copy of each of the
above structures at every re-execution of an SQL statement.
To simplify memory management, LEX::key_list and LEX::create_list
were added to LEX::alter_info, a fresh copy of which is created for
every execution.
The problem of crashing bug 22060 stemmed from the fact that the above
metnioned functions were not only modifying HA_CREATE_INFO structure
in LEX, but also were changing it to point to areas in volatile memory
of the execution memory root.
The patch solves this problem by creating and using an on-stack
copy of HA_CREATE_INFO in mysql_execute_command.
Additionally, this patch splits the part of mysql_alter_table
that analizes and rewrites information from the parser into
a separate function - mysql_prepare_alter_table, in analogy with
mysql_prepare_table, which is renamed to mysql_prepare_create_table.

SQLCOM_DROP_INDEX, which was a bug.
Just like CREATE INDEX, DROP INDEX is currently done via complete
table rebuild and is rightfully a slow administrative statement.
sql/sql_partition.cc:
Move is_partition_management() to sql_lex.cc
Adjust code to the new Alter_info.
sql/sql_table.cc:
Adjust mysql_alter_table, mysql_recreate_table, mysql_create_table,
mysql_prepare_table to new signatures.
Rename mysql_prepare_table to mysql_prepare_create_table. Make
sure it follows the convention and returns FALSE for success and
TRUE for error.
Move parts of mysql_alter_table to mysql_prepare_alter_table.
Move the first invokation of mysql_prepare_table from mysql_alter_table
to compare_tables, as it was needed only for the purpose
of correct comparison.
Since now Alter_info itself is created in the runtime mem root,
adjust mysql_prepare_table to always allocate memory in the
runtime memory root.
Remove dead code.

Bug #23667 "CREATE TABLE LIKE is not isolated from alteration
by other connections"
Bug #18950 "CREATE TABLE LIKE does not obtain LOCK_open"
As well as:
Bug #25578 "CREATE TABLE LIKE does not require any privileges
on source table".
The first and the second bugs resulted in various errors and wrong
binary log order when one tried to execute concurrently CREATE TABLE LIKE
statement and DDL statements on source table or DML/DDL statements on its
target table.
The problem was caused by incomplete protection/table-locking against
concurrent statements implemented in mysql_create_like_table() routine.
We solve it by simply implementing such protection in proper way.
Most of actual work for 5.1 was already done by fix for bug 20662 and
preliminary patch changing locking in ALTER TABLE.
The third bug allowed user who didn't have any privileges on table create
its copy and therefore circumvent privilege check for SHOW CREATE TABLE.
This patch solves this problem by adding privilege check, which was missing.
Finally it also removes some duplicated code from mysql_create_like_table()
and thus fixes bug #26869 "TABLE_LIST::table_name_length inconsistent with
TABLE_LIST::table_name".
mysql-test/r/create-big.result:
Added test coverage for concurrency-related issues with CREATE TABLE LIKE.
mysql-test/r/create.result:
Adjusted error-code in the test case after refactoring code that
implements CREATE TABLE ... LIKE.
mysql-test/r/grant2.result:
Added test for bug#25578 "CREATE TABLE LIKE does not require any privileges
on source table".
mysql-test/t/create-big.test:
Added test coverage for concurrency-related issues with CREATE TABLE LIKE.
mysql-test/t/create.test:
Adjusted error-code in the test case after refactoring code that
implements CREATE TABLE ... LIKE.
mysql-test/t/disabled.def:
Recent code changes ensured that CREATE TABLE LIKE statement is properly
isolated against other statements, so synchronization.test should no
longer fail (see fix for bug 20662 and preliminary patch for bug 23667
changing ALTER TABLE locking).
mysql-test/t/grant2.test:
Added test for bug#25578 "CREATE TABLE LIKE does not require any privileges
on source table".
sql/handler.h:
Introduced new flag for HA_CREATE_INFO::options in order to be able to
distinguish CREATE TABLE ... LIKE from other types of CREATE TABLE.
sql/mysql_priv.h:
mysql_create_like_table() now takes source table name not as a
Table_ident object but as regular table list element.
sql/sql_lex.h:
Removed LEX::like_name member. Now we use special flag in
LEX::create_info::options for distinguishing CREATE TABLE ... LIKE
from other types of CREATE TABLE and store name of source table as
regular element in statement's table list.
sql/sql_parse.cc:
CREATE TABLE ... LIKE implementation now uses statement's table list
for storing information about the source table. We also use flag
in LEX::create_info.options for distinguishing it from other types
of CREATE TABLE.
Finally CREATE TABLE ... LIKE now requires the same privileges on
the source tables as SHOW CREATE TABLE. Moved this privilege check
to check_show_create_table_access() function.
sql/sql_partition.cc:
Now we use special flag in LEX::create_info::options for distinguishing
CREATE TABLE ... LIKE from other types of CREATE TABLE and store name
of source table as regular element in statement's table list.
sql/sql_table.cc:
mysql_create_like_table():
- Commented and cleaned-up a bit code which is responsible for achieving
isolation from concurrent statements. Most of actual work was done by
fix for bug 20662 and preliminary patch changing locking locking in
ALTER TABLE, so here we do minor things like relaxing locking on
source table (we don't need lock on it, to have it open is enough) and
adjusting code to make it more friendly against code implementing I_S.
- Get rid of duplicated code related to source database/table name
handling. All these operations are already done in
st_select_lex::add_table_to_list(), so we achieve the same effect
by including source table into the statement's table list.
sql/sql_yacc.yy:
Now we use special flag in LEX::create_info::options for distinguishing
CREATE TABLE ... LIKE from other types of CREATE TABLE and store name

this patch as well.

sql/sql_table.cc:
mysql_create_like_table():
- Provided proper protection from concurrent statements.
This is achieved by keeping name-lock on the source table and holding
LOCK_open mutex during whole operation. This gives protection against
concurrent DDL on source table. Also holding this mutex makes copying
of .frm file, call to ha_create_table() and binlogging atomic against
concurrent DML and DDL operations on target table.
- Get rid of duplicated code related to source database/table name
handling. All these operations are already done in
st_select_lex::add_table_to_list(), so we achieve the same effect
by including source table into the statement's table list.
sql/sql_yacc.yy:
Now we use special flag in LEX::create_info::options for distinguishing
CREATE TABLE ... LIKE from other types of CREATE TABLE and store name
of source table as regular element in statement's table list.
Problem: we may get syntactically incorrect queries in the binary log
if we use a string value user variable executing a PS which
contains '... limit ?' clause, e.g.
prepare s from "select 1 limit ?";
set @a='qwe'; execute s using @a;
Fix: raise an error in such cases.
mysql-test/r/limit.result:
Fix for bug #28464: a string argument to 'limit ?' PS - replication fails
- test result
mysql-test/t/limit.test:
Fix for bug #28464: a string argument to 'limit ?' PS - replication fails
- test case
sql/item.cc:
Fix for bug #28464: a string argument to 'limit ?' PS - replication fails
- if Item_param::strict_type is set, check given and required types,
return an error if not equal.
sql/item.h:
Fix for bug #28464: a string argument to 'limit ?' PS - replication fails
- bool strict_type introduced, which indicates that a parameter value must be of
the required_result_type type.
- set_strict_type() function introduced to set required type.
sql/sql_yacc.yy:
Fix for bug #28464: a string argument to 'limit ?' PS - replication fails
- as we accept only INTs in the 'limit' clause set parameter's required type.

Bug #20662 "Infinite loop in CREATE TABLE IF NOT EXISTS ... SELECT
with locked tables"
Bug #20903 "Crash when using CREATE TABLE .. SELECT and triggers"
Bug #24738 "CREATE TABLE ... SELECT is not isolated properly"
Bug #24508 "Inconsistent results of CREATE TABLE ... SELECT when
temporary table exists"
Deadlock occured when one tried to execute CREATE TABLE IF NOT
EXISTS ... SELECT statement under LOCK TABLES which held
read lock on target table.
Attempt to execute the same statement for already existing
target table with triggers caused server crashes.
Also concurrent execution of CREATE TABLE ... SELECT statement
and other statements involving target table suffered from
various races (some of which might've led to deadlocks).
Finally, attempt to execute CREATE TABLE ... SELECT in case
when a temporary table with same name was already present
led to the insertion of data into this temporary table and
creation of empty non-temporary table.
All above problems stemmed from the old implementation of CREATE
TABLE ... SELECT in which we created, opened and locked target
table without any special protection in a separate step and not
with the rest of tables used by this statement.
This underminded deadlock-avoidance approach used in server
and created window for races. It also excluded target table
from prelocking causing problems with trigger execution.
The patch solves these problems by implementing new approach to
handling of CREATE TABLE ... SELECT for base tables.
We try to open and lock table to be created at the same time as
the rest of tables used by this statement. If such table does not
exist at this moment we create and place in the table cache special
placeholder for it which prevents its creation or any other usage
by other threads.
We still use old approach for creation of temporary tables.
Note that we have separate fix for 5.0 since there we use slightly
different less intrusive approach.
mysql-test/r/create.result:
Extended test coverage for CREATE TABLE ... SELECT. In particular added
tests for bug #24508 "Inconsistent results of CREATE TABLE ... SELECT
when temporary table exists" and bug #20662 "Infinite loop in CREATE
TABLE IF NOT EXISTS ... SELECT with locked tables".
mysql-test/r/trigger.result:
Added test case for bug #20903 "Crash when using CREATE TABLE .. SELECT
and triggers"
mysql-test/t/create.test:
Extended test coverage for CREATE TABLE ... SELECT. In particular added
tests for bug #24508 "Inconsistent results of CREATE TABLE ... SELECT
when temporary table exists" and bug #20662 "Infinite loop in CREATE
TABLE IF NOT EXISTS ... SELECT with locked tables".
mysql-test/t/trigger.test:
Added test case for bug #20903 "Crash when using CREATE TABLE .. SELECT
and triggers"
sql/lock.cc:
Now for creation of name-lock placeholder lock_table_name() uses
auxiliary function table_cache_insert_placeholder().
sql/mysql_priv.h:
Removed declaration of non-existing build_table_path() routine.
The former mysql_create_table_internal() was renamed to
mysql_create_table_no_lock() and now exposed to other modules to
give them opportunity of creation of tables in cases when name-lock
is already obtained.
reopen_name_locked_table() now has 3rd argument which controls linking
in of table being opened into THD::open_tables (this is useful in
cases when placeholder used for name-locking is already linked into
this list).
Added declaration of auxiliary function table_cache_insert_placeholder()
which is used for creation of table placeholders for name-locking.
Added declaration of lock_table_name_if_not_cached() which can be
used to take an exclusive name-lock on table if there are no records
for it in table cache.
Changed signature of unlink_open_table() function to simplify its use
and make it useful for table placeholders and tables that are only open.
Added auxiliary drop_open_table() routine.
Moved declaration of refresh_version to table.h header to make it
accessible from inline methods of TABLE class.
MYSQL_OPEN_IGNORE_LOCKED_TABLES flag is no longer used. Instead
MYSQL_OPEN_TEMPORARY_ONLY option was added.
sql/sql_base.cc:
Added support for the new approach to the handling of CREATE TABLE
... SELECT for base tables.
Now we try to open and lock table to be created at the same time as
the rest of tables used by this statement. If such table does not
exist at this moment we create and place in the table cache special
placeholder for it which prevents its creation or any other usage
by other threads.
Note significant distinctions of this placeholder from the placeholder
used for normal name-lock: 1) It is treated like open table by other
name-locks so it does not allow name-lock taking operations like DROP
TABLE or RENAME TABLE to proceed. 2) it is linked into THD::open_tables
list and automatically removed during close_thread_tables() call
open_tables():
Implemented logic described above. To do this added
auxiliary check_if_table_exists() function.
Removed support for MYSQL_OPEN_IGNORE_LOCKED_TABLES option
which is no longer used.
Added MYSQL_OPEN_TEMPORARY_ONLY which is used to restrict
search for temporary tables only.
close_cached_tables()/close_thread_table()/reopen_tables()/
close_old_data_files()/table_is_used()/remove_table_from_cache():
Added support for open placeholders (note that we also use them
when we need to re-open tables during flush).
unlink_open_table():
Changed function signature to simplify its use and to make
useful for open placeholders and tables which are only
open and not locked.
Added auxiliary drop_open_table() routine.
reopen_name_locked_table():
Now has 3rd argument which controls linking in of table being
opened into THD::open_tables (this is useful in cases when
placeholder used for name-locking is already linked into
this list).
Added auxiliary table_cache_insert_placeholder() routine which
simplifies creation of placeholders used for name-locking.
Added lock_table_name_if_not_cached() which can be used to take
an exclusive name-lock on table if there are no records for it
in table cache.
sql/sql_handler.cc:
Adjusted mysql_ha_mark_tables_for_reopen() routine to properly
handle placeholders which now can be linked into open tables
list.
sql/sql_insert.cc:
Introduced new approach to handling of base tables in CREATE TABLE
... SELECT statement.
Now we try to open and lock table to be created at the same time as
the rest of tables used by this statement. If such table does not
exist at this moment we create and place in the table cache special
placeholder for it which prevents its creation or any other usage
by other threads. By doing this we avoid races which existed with
previous approach in which we created, opened and locked target in
separate step without any special protection.
This also allows properly calculate prelocking set in cases when
target table already exists and has some on insert triggers.
Note that we don't employ the same approach for temporary tables
(this is okay as such tables are unaffected by other threads).
Changed create_table_from_items() and methods of select_create
class to implement this approach.
sql/sql_parse.cc:
The new approach to handling of CREATE TABLE ... SELECT for
base tables assumes that all tables (including table to be
created) are opened and (or) locked at the same time.
So in cases when we create base table we have to pass to
open_and_lock_tables() table list which includes target table.
sql/sql_prepare.cc:
The new approach to handling of CREATE TABLE ... SELECT for
base tables assumes that all tables (including table to be
created) are opened and (or) locked at the same time.
So in cases when we create base table we have to pass to
open_and_lock_tables() table list which includes target table.
sql/sql_table.cc:
Changed mysql_create_table(), mysql_create_like_table() and
mysql_alter_table() (in rename case) to obtain exclusive name-lock
on the non-temporary table which is going to be created (to which
we going to rename). This ensures that not only destination table
doesn't exist on disk but also that there are no placeholder in
table cache for it (i.e. there is no CREATE TABLE ... SELECT operation
in progress for it). Note that to avoid deadlocks while taking these
name-locks this code assumes that existence of any record for table in
table cache (even name-lock) means that table exists. Altough such
check can lead to false positives these should occur only in case of
highly concurrent DDL operations on the table and should not break
binary logging.
Renamed mysql_create_table_internal() to mysql_create_table_no_lock()
and made it accessible from other files to give them ability to create
table in situation when name-lock is already obtained or not relevant.
Adjusted calls to reopen_name_locked_table(), which now takes
extra argument, which controls linking of open table into
THD::open_tables list.
Removed redundant setting of table's 'version' field before calls
to close_cached_table(). This function will set it to 0 itself
anyway.
sql/sql_trigger.cc:
reopen_name_locked_tables() now has one more argument which controls
linking of opened table into the THD::open_tables list.
sql/sql_yacc.yy:
The new approach to handling of CREATE TABLE ... SELECT statement
for base tables assumes that all tables including table to be
created are open and (or) locked at the same time. Therefore
we need to set correct lock for target table.
sql/table.h:
Moved declaration of refresh_version variable from mysql_priv.h
to make it accessible from inline methods of TABLE class.
Renamed TABLE::locked_by_flush member to open_placeholder since
now it is also used for taking exclusive name-lock and not only
by flush.
Introduced TABLE::is_name_opened() helper method which can be used
to distinguish TABLE instances corresponding to open tables or
placeholders for them from closed instances (e.g. due to their old
version). Also introduced TABLE::needs_reopen_or_name_lock() helper
which allows to check if TABLE instance corresponds to outdated
version of table or to name-lock placeholder.
Introduced TABLE_LIST::create member which marks elements of
table list corresponds to the table to be created.
Adjusted TABLE_LIST::placeholder() method to take into account
name-lock placeholders for tables to be created (this, for example,
allows to properly handle such placeholders in lock_tables()).
Finally, moved currently unused TABLE::open_next/open_prev
members under ifdef NOT_YET.
mysql-test/r/create_select-big.result:
New BitKeeper file ``mysql-test/r/create_select-big.result''
mysql-test/t/create_select-big.test:
New BitKeeper file ``mysql-test/t/create_select-big.test''

We still use old approach for creation of temporary tables.
Also note that we decided to postpone introduction of some tests
for concurrent behaviour of CREATE TABLE ... SELECT till 5.1.
The main reason for this is absence in 5.0 ability to set @@debug
variable at runtime, which can be circumvented only by using several
test files with individual .opt files. Since the latter is likely
to slowdown test-suite unnecessary we chose not to push this tests
into 5.0, but run them manually for this version and later push
their optimized version into 5.1
mysql-test/r/create.result:
Extended test coverage for CREATE TABLE ... SELECT. In particular added
tests for bug #24508 "Inconsistent results of CREATE TABLE ... SELECT
when temporary table exists" and bug #20662 "Infinite loop in CREATE
TABLE IF NOT EXISTS ... SELECT with locked tables".
mysql-test/r/trigger.result:
Added test case for bug #20903 "Crash when using CREATE TABLE .. SELECT
and triggers"
mysql-test/t/create.test:
Extended test coverage for CREATE TABLE ... SELECT. In particular added
tests for bug #24508 "Inconsistent results of CREATE TABLE ... SELECT
when temporary table exists" and bug #20662 "Infinite loop in CREATE
TABLE IF NOT EXISTS ... SELECT with locked tables".
mysql-test/t/trigger.test:
Added test case for bug #20903 "Crash when using CREATE TABLE .. SELECT
and triggers"
sql/lock.cc:
Now for creation of name-lock placeholder in lock_table_name() we use
auxiliary function table_cache_insert_placeholder().
sql/mysql_priv.h:
Made build_table_path() function available outside of sql_table.cc file.
reopen_name_locked_table() now has 3rd argument which controls linking
in of table being opened into THD::open_tables (this is useful in
cases when placeholder used for name-locking is already linked into
this list).
Added declaration of auxiliary function table_cache_insert_placeholder()
which is used for creation of table placeholders for name-locking.
Added declaration of table_cache_has_open_placeholder() function which
can be used for checking if table cache contains an open placeholder for
the table and if this placeholder was created by another thread.
(This function is needed only in 5.0 where we use it in various versions
of CREATE TABLE in order to protect it from concurrent CREATE TABLE
... SELECT operations for the table. Starting from 5.1 we use different
approach so it is going to be removed there).
Made close_old_data_files() static within sql_base.cc file.
Added auxiliary drop_open_table() routine.
Moved declaration of refresh_version to table.h header to make it
accessible from inline methods of TABLE class.
MYSQL_OPEN_IGNORE_LOCKED_TABLES flag is no longer used. Instead
MYSQL_OPEN_TEMPORARY_ONLY option was added.
sql/sql_base.cc:
Added support for the new approach to the handling of CREATE TABLE
... SELECT for base tables.
Now we try to open and lock table to be created at the same time as
the rest of tables used by this statement. If such table does not
exist at this moment we create and place in the table cache special
placeholder for it which prevents its creation or any other usage
by other threads.
Note significant distinctions of this placeholder from the placeholder
used for normal name-lock: 1) It is treated like open table by other
name-locks so it does not allow name-lock taking operations like DROP
TABLE or RENAME TABLE to proceed. 2) it is linked into THD::open_tables
list and automatically removed during close_thread_tables() call.
open_tables():
Implemented logic described above. To do this added
auxiliary check_if_table_exists() function.
Removed support for MYSQL_OPEN_IGNORE_LOCKED_TABLES option
which is no longer used.
Added MYSQL_OPEN_TEMPORARY_ONLY which is used to restrict
search for temporary tables only.
close_cached_tables()/close_thread_table()/reopen_tables()/
close_old_data_files()/table_is_used()/remove_table_from_cache():
Added support for open placeholders (note that we also use them
when we need to re-open tables during flush).
Added auxiliary drop_open_table() routine.
reopen_name_locked_table():
Now has 3rd argument which controls linking in of table being
opened into THD::open_tables (this is useful in cases when
placeholder used for name-locking is already linked into
this list).
Added auxiliary table_cache_insert_placeholder() routine which
simplifies creation of placeholders used for name-locking.
Added table_cache_has_open_placeholder() function which can be
used for checking if table cache contains an open placeholder for
the table and if this placeholder was created by another thread.
(This function is needed only in 5.0 where we use it in various versions
of CREATE TABLE in order to protect it from concurrent CREATE TABLE
... SELECT operations for the table. Starting from 5.1 we use different
approach so it is going to be removed there).
sql/sql_handler.cc:
Adjusted mysql_ha_mark_tables_for_reopen() routine to properly
handle placeholders which now can be linked into open tables
list.
sql/sql_insert.cc:
Introduced new approach to handling of base tables in CREATE TABLE
... SELECT statement.
Now we try to open and lock table to be created at the same time as
the rest of tables used by this statement. If such table does not
exist at this moment we create and place in the table cache special
placeholder for it which prevents its creation or any other usage
by other threads. By doing this we avoid races which existed with
previous approach in which we created, opened and locked target in
separate step without any special protection.
This also allows properly calculate prelocking set in cases when
target table already exists and has some on insert triggers.
Note that we don't employ the same approach for temporary tables
(this is okay as such tables are unaffected by other threads).
Changed create_table_from_items() and select_create methods to
implement this approach.
sql/sql_parse.cc:
The new approach to handling of CREATE TABLE ... SELECT for
base tables assumes that all tables (including table to be
created) are opened and (or) locked at the same time.
So in cases when we create base table we have to pass to
open_and_lock_tables() table list which includes target table.
sql/sql_prepare.cc:
The new approach to handling of CREATE TABLE ... SELECT for
base tables assumes that all tables (including table to be
created) are opened and (or) locked at the same time.
So in cases when we create base table we have to pass to
open_and_lock_tables() table list which includes target table.
sql/sql_table.cc:
Now mysql_create_table_internal(), mysql_create_like_table() and
mysql_alter_table() not only check that destination table doesn't
exist on disk but also check that there is no create placeholder
in table cache for it (i.e. there is no CREATE TABLE ... SELECT
operation in progress for it). Note that starting from 5.1 we
use different approach in order to to protect CREATE TABLE ... SELECT
from concurrent CREATE TABLE (ALTER TABLE ... RENAME) operations,
the latter simply take name-locks on table before its creation
(on target table name before renaming).
Also made build_table_path() available from other files and
asjusted calls to reopen_name_locked_table(), which now takes
extra argument, which controls linking of open table into
THD::open_tables list.
sql/sql_trigger.cc:
reopen_name_locked_tables() now has one more argument which controls
linking of opened table into the THD::open_tables list.
sql/sql_yacc.yy:
The new approach to handling of CREATE TABLE ... SELECT statement
for base tables assumes that all tables including table to be
created are open and (or) locked at the same time. Therefore
we need to set correct lock for target table.
sql/table.h:
Moved declaration of refresh_version variable from mysql_priv.h
to make it accessible from inline methods of TABLE class.
Renamed TABLE::locked_by_flush member to open_placeholder since
now it is also used for taking exclusive name-lock and not only
by flush.
Introduced TABLE::is_name_opened() helper method which can be used
to distinguish TABLE instances corresponding to open tables or
placeholders for them from closed instances (e.g. due to their old
version). Also introduced TABLE::needs_reopen_or_name_lock() helper
which allows to check if TABLE instance corresponds to outdated
version of table or to name-lock placeholder.
Introduced TABLE_LIST::create member which marks elements of
table list corresponds to the table to be created.
Adjusted TABLE_LIST::placeholder() method to take into account
name-lock placeholders for tables to be created (this, for example,
allows to properly handle such placeholders in lock_tables()).

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

manual merge
Before this fix, the parser would sometime change where a token starts by
altering Lex_input_string::tok_start, which later confused the code in
sql_yacc.yy that needs to capture the source code of a SQL statement,
like to represent the body of a stored procedure.
This line of code in sql_lex.cc :
case MY_LEX_USER_VARIABLE_DELIMITER:
lip->tok_start= lip->ptr; // Skip first `
would <skip the first back quote> ... and cause the bug reported.
In general, the responsibility of sql_lex.cc is to *find* where token are
in the SQL text, but is *not* to make up fake or incomplete tokens.
With a quoted label like `my_label`, the token starts on the first quote.
Extracting the token value should not change that (it did).
With this fix, the lexical analysis has been cleaned up to not change
lip->tok_start (in the case found for this bug).
The functions get_token() and get_quoted_token() now have an extra
parameters, used when some characters from the beginning of the token need
to be skipped when extracting a token value, like when extracting 'AB' from
'0xAB', for example, for a HEX_NUM token.
This exposed a bad assumption in Item_hex_string and Item_bin_string,
which has been fixed:
The assumption was that the string given, 'AB', was in fact preceded in
memory by '0x', which might be false (it can be preceded by "x'" and
followed by "'" -- or not be preceded by valid memory at all)
If a name is needed for Item_hex_string or Item_bin_string, the name is
taken from the original and true source code ('0xAB'), and assigned in
the select_item rule, instead of relying on assumptions related to how
memory is used.

The issue found with bug 25411 is due to the function skip_rear_comments()
which damages the source code while implementing a work around.
The root cause of the problem is in the lexical analyser, which does not
process special comments properly.
For special comments like :
[1] aaa /*!50000 bbb */ ccc
since 5.0 is a version older that the current code, the parser is in lining
the content of the special comment, so that the query to process is
[2] aaa bbb ccc
However, the text of the query captured when processing a stored procedure,
stored function or trigger (or event in 5.1), can be after rebuilding it:
[3] aaa bbb */ ccc
which is wrong.
To fix bug 25411 properly, the lexical analyser needs to return [2] when
in lining special comments.
In order to implement this, some preliminary cleanup is required in the code,
which is implemented by this patch.
Before this change, the structure named LEX (or st_lex) contains attributes
that belong to lexical analysis, as well as attributes that represents the
abstract syntax tree (AST) of a statement.
Creating a new LEX structure for each statements (which makes sense for the
AST part) also re-initialized the lexical analysis phase each time, which
is conceptually wrong.
With this patch, the previous st_lex structure has been split in two:
- st_lex represents the Abstract Syntax Tree for a statement. The name "lex"
has not been changed to avoid a bigger impact in the code base.
- class lex_input_stream represents the internal state of the lexical
analyser, which by definition should *not* be reinitialized when parsing
multiple statements from the same input stream.
This change is a pre-requisite for bug 25411, since the implementation of
lex_input_stream will later improve to deal properly with special comments,
and this processing can not be done with the current implementation of
sp_head::reset_lex and sp_head::restore_lex, which interfere with the lexer.
This change set alone does not fix bug 25411.

This patch removes the SLAVESIDE_DISABLED token from the event status clause
and adds the ability to mark an event as status = SLAVESIDE_DISABLED by using
the syntax DISABLE ON SLAVE instead.
The patch also adds tests to rpl_events to check the new syntax.

This changeset adds replication of events and user-defined functions.
There are several bug reports involved in this change:
BUG#16421, BUG#17857, BUG#20384:
This patch modifies the mysql.events table to permit the addition of
another enum value for the status column. The column now has values
of ('DISABLED','SLAVESIDE_DISABLED','ENABLED'). A status of
SLAVESIDE_DISABLED is set on the slave during replication of events.
This enables users to determine which events werereplicated from the
master and to later enable them if they promote the slave to a master.
The CREATE, ALTER, and DROP statements are binlogged.
A new test was added for replication of events (rpl_events).
BUG#17671:
This patch modifies the code to permit logging of user-defined functions.
Note: this is the CREATE FUNCTION ... SONAME variety. A more friendly error
message to be displayed should a replicated user-defined function not be
found in the loadable library or if the library is missing from the
slave.The CREATE andDROP statements are binlogged. A new test was added
for replication of user-defined functions (rpl_udf).
The patch also adds a new column to the mysql.event table named
'originator' that is used to store the server_id of the server that
the event originated on. This enables users to promote a slave to a
master and later return the promoted slave to a slave and disable the
replicated events.
mysql-test/lib/init_db.sql:
WL#3629 - Replication of Invocation and Invoked Feature
This patch adds the SLAVESIDE_DISABLED to the list of enumerated
values for the mysql.event table.
This patch adds the column 'originator' to the mysql.event table.
mysql-test/r/events.result:
WL#3629 - Replication of Invocation and Invoked Feature
This patch adds the 'originator' column to the events test results.
This was necessary to ensure the manual insert into mysql.event table
succeeds because the originator column is set to NOT NULL.
mysql-test/r/events_grant.result:
WL#3629 - Replication of Invocation and Invoked Feature
This patch adds the 'originator' column to the events_grant test results.
This was necessary to ensure the manual insert into mysql.event table
succeeds because the originator column is set to NOT NULL.
mysql-test/r/events_restart_phase1.result:
WL#3629 - Replication of Invocation and Invoked Feature
This patch adds the 'originator' column to the events_restart_phase1
test results. This was necessary to ensure the manual insert into
mysql.event table succeeds because the originator column is set to
NOT NULL.
mysql-test/r/system_mysql_db.result:
WL#3629 - Replication of Invocation and Invoked Feature
This patch adds the SLAVESIDE_DISABLED to the list of enumerated

This patch adds the column 'originator' to the mysql.event table.
These changes to the result file were necessary to ensure correct test
results.
mysql-test/t/events.test:

This patch adds the 'originator' column to the events
test. This was necessary to ensure the manual insert into
mysql.event table succeeds because the originator column is set to
NOT NULL.

test. This was necessary to ensure the manual insert into
mysql.event table succeeds because the originator column is set to
NOT NULL.

sql/event_data_objects.cc:
WL#3629 - Replication of Invocation and Invoked Features
This patch modifies the code to permit processing of the new enum
SLAVESIDE_DISABLED which is set on the slave during replication
of events.
This patch uses the new Event_basic:: enumerated values.
sql/event_data_objects.h:
WL#3629 - Replication of Invocation and Invoked Features
This patch moves the duplicated enumeration values for ENABLED,
SLAVESIDE_DISABLED, and DISABLED to the Event_basic class removing
them from the other Event_* classes.
sql/event_db_repository.cc:
WL#3629 - Replication of Invocation and Invoked Features
This patch modifies the code to permit processing of the new enum
SLAVESIDE_DISABLED which is set on the slave during replication

Before this fix, the parser would accept illegal code in SQL exceptions
handlers, that later causes the runtime to crash when executing the code,
due to memory violations in the exception handler stack.
The root cause of the problem is instructions within an exception handler
that jumps to code located outside of the handler. This is illegal according
to the SQL 2003 standard, since labels located outside the handler are not
supposed to be visible (they are "out of scope"), so any instruction that
jumps to these labels, like ITERATE or LEAVE, should not parse.
The section of the standard that is relevant for this is :
SQL:2003 SQL/PSM (ISO/IEC 9075-4:2003)
section 13.1 <compound statement>,
syntax rule 4
<quote>
The scope of the <beginning label> is CS excluding every <SQL schema
statement> contained in CS and excluding every
<local handler declaration list> contained in CS. <beginning label> shall
not be equivalent to any other <beginning label>s within that scope.
</quote>
With this fix, the C++ class sp_pcontext, which represent the "parsing
context" tree (a.k.a symbol table) of a stored procedure, has been changed
as follows:
- constructors have been cleaned up, so that only building a root node for
the tree is public; building nodes inside a tree is not public.
- a new member, m_label_scope, indicates if a given syntactic context
belongs to a DECLARE HANDLER block,
- label resolution, in the method find_label(), has been changed to
implement the restriction of scope regarding labels used in a compound
statement.
The actions in the parser, when parsing the body of a SQL exception handler,
have been changed as follows:
- the implementation of an exception handler (DECLARE HANDLER) now creates
explicitly a new sp_pcontext, to isolate the code inside the handler from
the containing compound statement context.
- registering exception handlers as a result occurs in the parent context,
see the rule sp_hcond_element
- the code in sp_hcond_list has been cleaned up, to avoid code duplication
In addition, the flags IN_SIMPLE_CASE and IN_HANDLER, declared in sp_head.h
have been removed, since they are unused and broken by design (as seen with
Bug 19194 (Right recursion in parser for CASE causes excessive stack usage,
limitation), representing a stack in a single flag is not possible.
Tests in sp-error have been added to show that illegal constructs are now
rejected.
Tests in sp have been added for code coverage, to show that ITERATE or LEAVE
statements are legal when jumping to a label in scope, inside the body of
an exception handler.

The problem was that some facilities (like CONVERT_TZ() function or
server HELP statement) may require implicit access to some tables in
'mysql' database. This access was done by ordinary means of adding
such tables to the list of tables the query is going to open.
However, if we issued LOCK TABLES before that, we would get "table
was not locked" error trying to open such implicit tables.
The solution is to treat certain tables as MySQL system tables, like
we already do for mysql.proc. Such tables may be opened for reading
at any moment regardless of any locks in effect. The cost of this is
that system table may be locked for writing only together with other
system tables, it is disallowed to lock system tables for writing and
have any other lock on any other table.
After this patch the following tables are treated as MySQL system
tables:
mysql.help_category
mysql.help_keyword
mysql.help_relation
mysql.help_topic
mysql.proc (it already was)
mysql.time_zone
mysql.time_zone_leap_second
mysql.time_zone_name
mysql.time_zone_transition
mysql.time_zone_transition_type
These tables are now opened with open_system_tables_for_read() and
closed with close_system_tables(), or one table may be opened with
open_system_table_for_update() and closed with close_thread_tables()
(the latter is used for mysql.proc table, which is updated as part of
normal MySQL server operation). These functions may be used when
some tables were opened and locked already.
NOTE: online update of time zone tables is not possible during
replication, because there's no time zone cache flush neither on LOCK
TABLES, nor on FLUSH TABLES, so the master may serve stale time zone
data from cache, while on slave updated data will be loaded from the
time zone tables.

fixes).
The legend: on a replication slave, in case a trigger creation
was filtered out because of application of replicate-do-table/
replicate-ignore-table rule, the parsed definition of a trigger was not
cleaned up properly. LEX::sphead member was left around and leaked
memory. Until the actual implementation of support of
replicate-ignore-table rules for triggers by the patch for Bug 24478 it
was never the case that "case SQLCOM_CREATE_TRIGGER"
was not executed once a trigger was parsed,
so the deletion of lex->sphead there worked and the memory did not leak.
The fix:
The real cause of the bug is that there is no 1 or 2 places where
we can clean up the main LEX after parse. And the reason we
can not have just one or two places where we clean up the LEX is
asymmetric behaviour of MYSQLparse in case of success or error.
One of the root causes of this behaviour is the code in Item::Item()
constructor. There, a newly created item adds itself to THD::free_list
- a single-linked list of Items used in a statement. Yuck. This code
is unaware that we may have more than one statement active at a time,
and always assumes that the free_list of the current statement is
located in THD::free_list. One day we need to be able to explicitly
allocate an item in a given Query_arena.
Thus, when parsing a definition of a stored procedure, like
CREATE PROCEDURE p1() BEGIN SELECT a FROM t1; SELECT b FROM t1; END;
we actually need to reset THD::mem_root, THD::free_list and THD::lex
to parse the nested procedure statement (SELECT *).
The actual reset and restore is implemented in semantic actions
attached to sp_proc_stmt grammar rule.
The problem is that in case of a parsing error inside a nested statement
Bison generated parser would abort immediately, without executing the
restore part of the semantic action. This would leave THD in an
in-the-middle-of-parsing state.
This is why we couldn't have had a single place where we clean up the LEX
after MYSQLparse - in case of an error we needed to do a clean up
immediately, in case of success a clean up could have been delayed.
This left the door open for a memory leak.
One of the following possibilities were considered when working on a fix:
- patch the replication logic to do the clean up. Rejected
as breaks module borders, replication code should not need to know the
gory details of clean up procedure after CREATE TRIGGER.
- wrap MYSQLparse with a function that would do a clean up.
Rejected as ideally we should fix the problem when it happens, not
adjust for it outside of the problematic code.
- make sure MYSQLparse cleans up after itself by invoking the clean up
functionality in the appropriate places before return. Implemented in
this patch.
- use %destructor rule for sp_proc_stmt to restore THD - cleaner
than the prevoius approach, but rejected
because needs a careful analysis of the side effects, and this patch is
for 5.0, and long term we need to use the next alternative anyway
- make sure that sp_proc_stmt doesn't juggle with THD - this is a
large work that will affect many modules.
Cleanup: move main_lex and main_mem_root from Statement to its
only two descendants Prepared_statement and THD. This ensures that
when a Statement instance was created for purposes of statement backup,
we do not involve LEX constructor/destructor, which is fairly expensive.
In order to track that the transformation produces equivalent
functionality please check the respective constructors and destructors
of Statement, Prepared_statement and THD - these members were
used only there.
This cleanup is unrelated to the patch.

sql/sql_lex.h:
Declare st_lex::restore_lex().
sql/sql_parse.cc:
Consolidate the calls to unit.cleanup() and deletion of lex->sphead
in mysql_parse (COM_QUERY handler)
sql/sql_prepare.cc:
No need to delete lex->sphead to restore memory roots now in case of a
parse error - this is done automatically inside MYSQLparse
sql/sql_trigger.cc:
This code could lead to double deletion apparently, as in case
of an error lex.sphead was never reset.
sql/sql_yacc.yy:
Trap all returns from the parser to ensure that MySQL-specific cleanup
is invoked: we need to restore the global state of THD and LEX in
case of a parsing error. In case of a parsing success this happens as
part of normal grammar reduction process.

can be specified
Currently MySQL allows one to specify what indexes to ignore during
join optimization. The scope of the current USE/FORCE/IGNORE INDEX
statement is only the FROM clause, while all other clauses are not
affected.
However, in certain cases, the optimizer
may incorrectly choose an index for sorting and/or grouping, and
produce an inefficient query plan.
This task provides the means to specify what indexes are
ignored/used for what operation in a more fine-grained manner, thus
making it possible to manually force a better plan. We do this
by extending the current IGNORE/USE/FORCE INDEX syntax to:
IGNORE/USE/FORCE INDEX [FOR {JOIN | ORDER | GROUP BY}]
so that:
- if no FOR is specified, the index hint will apply everywhere.
- if MySQL is started with the compatibility option --old_mode then
an index hint without a FOR clause works as in 5.0 (i.e, the
index will only be ignored for JOINs, but can still be used to
compute ORDER BY).
See the WL#3527 for further details.

This patch fixes problem that LOAD DATA could use different
character sets when loading files on master and on slave sides:
- Adding replication of thd->variables.collation_database
- Adding optional character set clause into LOAD DATA
Note, the second way, with explicit CHARACTER SET clause
should be the recommended way to load data using an alternative
character set.
The old way, using "SET @@character_set_database=xxx" should be
gradually depricated.

Bug#24795: SHOW PROFILE
Profiling is only partially functional on some architectures. Where
there is no getrusage() system call, presently Null values are
returned where it would be required. Notably, Windows needs some love
applied to make it as useful.
Syntax this adds:
SHOW PROFILES
SHOW PROFILE [types] [FOR QUERY n] [OFFSET n] [LIMIT n]
where "n" is an integer
and "types" is zero or many (comma-separated) of
"CPU"
"MEMORY" (not presently supported)
"BLOCK IO"
"CONTEXT SWITCHES"
"PAGE FAULTS"
"IPC"
"SWAPS"
"SOURCE"
"ALL"
It also adds a session variable (boolean) "profiling", set to "no"
by default, and (integer) profiling_history_size, set to 15 by
default.
This patch abstracts setting THDs' "proc_info" behind a macro that
can be used as a hook into the profiling code when profiling
support is compiled in. All future code in this line should use
that mechanism for setting thd->proc_info.
---
Tests are now set to omit the statistics.
---
Adds an Information_schema table, "profiling" for access to
"show profile" data.

Several problems fixed:
1. There was a "catch-all" context initialization in setup_tables()
that was causing the table that we insert into to be visible in the
SELECT part of an INSERT .. SELECT .. statement with no tables in
its FROM clause. This was making sure all the under-initialized
contexts in various parts of the code are not left uninitialized.
Fixed by removing the "catch-all" statement and initializing the
context in the parser.
2. Incomplete name resolution context when resolving the right-hand
values in the ON DUPLICATE KEY UPDATE ... part of an INSERT ... SELECT ...
caused columns from NATURAL JOIN/JOIN USING table references in the
FROM clause of the select to be unavailable.
Fixed by establishing a proper name resolution context.
3. When setting up the special name resolution context for problem 2
there was no check for cases where an aggregate function without a
GROUP BY effectively takes the column from the SELECT part of an
INSERT ... SELECT unavailable for ON DUPLICATE KEY UPDATE.
Fixed by checking for that condition when setting up the name
resolution context.

operations)
Before this change, the boolean predicates:
- X IS TRUE,
- X IS NOT TRUE,
- X IS FALSE,
- X IS NOT FALSE
were implemented by expanding the Item tree in the parser, by using a
construct like:
Item_func_if(Item_func_ifnull(X, <value>), <value>, <value>)
Each <value> was a constant integer, either 0 or 1.
A bug in the implementation of the function IF(a, b, c), in
Item_func_if::fix_length_and_dec(), would cause the following :
When the arguments b and c are both unsigned, the result type of the
function was signed, instead of unsigned.
When the result of the if function is signed, space for the sign could be
counted twice (in the max() expression for a signed argument, and in the
total), causing the member max_length to be too high.
An effect of this is that the final type of IF(x, int(1), int(1)) would be
int(2) instead of int(1).
With this fix, the problems found in Item_func_if::fix_length_and_dec()
have been fixed.
While it's semantically correct to represent 'X IS TRUE' with
Item_func_if(Item_func_ifnull(X, <value>), <value>, <value>),
there are however more problems with this construct.
a)
Building the parse tree involves :
- creating 5 Item instances (3 ints, 1 ifnull, 1 if),
- creating each Item calls my_pthread_getspecific_ptr() once in the operator
new(size), and a second time in the Item::Item() constructor, resulting
in a total of 10 calls to get the current thread.
Evaluating the expression involves evaluating up to 4 nodes at runtime.
This representation could be greatly simplified and improved.
b)
Transforming the parse tree internally with if(ifnull(...)) is fine as long
as this transformation is internal to the server implementation.
With views however, the result of the parse tree is later exposed by the
::print() functions, and stored as part of the view definition.
Doing this has long term consequences:
1)
The original semantic 'X IS TRUE' is lost, and replaced by the
if(ifnull(...)) expression. As a result, SHOW CREATE VIEW does not restore
the original code.
2)
Should a future version of MySQL implement the SQL BOOLEAN data type for
example, views created today using 'X IS NULL' can be exported using
mysqldump, and imported again. Such views would be converted correctly and
automatically to use a BOOLEAN column in the future version.
With 'X IS TRUE' and the current implementations, views using these
"boolean" predicates would not be converted during the export/import, and
would use integer columns instead.
The difference traces back to how SHOW CREATE VIEW preserves 'X IS NULL' but
does not preserve the 'X IS TRUE' semantic.
With this fix, internal representation of 'X IS TRUE' booleans predicates
has changed, so that:
- dedicated Item classes are created for each predicate,
- only 1 Item is created to represent 1 predicate
- my_pthread_getspecific_ptr() is invoked 1 time instead of 10
- SHOW CREATE VIEW preserves the original semantic, and prints 'X IS TRUE'.
Note that, because of the fix in Item_func_if, views created before this fix
will:
- correctly use a int(1) type instead of int(2) for boolean predicates,
- incorrectly print the if(ifnull(...), ...) expression in SHOW CREATE VIEW,
since the original semantic (X IS TRUE) has been lost.
- except for the syntax used in SHOW CREATE VIEW, these views will operate
properly, no action is needed.
Views created after this fix will operate correctly, and will preserve the
original code semantic in SHOW CREATE VIEW.

Two problems here:
Problem 1:
While constructing the join columns list the optimizer does as follows:
1. Sets the join_using_fields/natural_join members of the right JOIN
operand.
2. Makes a "table reference" (TABLE_LIST) to parent the two tables.
3. Assigns the join_using_fields/is_natural_join of the wrapper table
using join_using_fields/natural_join of the rightmost table
4. Sets join_using_fields to NULL for the right JOIN operand.
5. Passes the parent table up to the same procedure on the upper
level.
Step 1 overrides the the join_using_fields that are set for a nested
join wrapping table in step 4.
Fixed by making a designated variable SELECT_LEX::prev_join_using to
pass the data from step 1 to step 4 without destroying the wrapping
table data.
Problem 2:
The optimizer checks for ambiguous columns while transforming
NATURAL JOIN/JOIN USING to JOIN ON. While doing that there was no
distinction between columns that are used in the generated join
condition (where ambiguity can be checked) and the other columns
(where ambiguity can be checked only when resolving references
coming from outside the JOIN construct itself).
Fixed by allowing the non-USING columns to be present in multiple
copies in both sides of the join and moving the ambiguity check
to the place where unqualified references to the join columns are
resolved (find_field_in_natural_join()).

Before this fix, a IN predicate of the form: "IN (( subselect ))", with two
parenthesis, would be evaluated as a single row subselect: if the subselect
returns more that 1 row, the statement would fail.
The SQL:2003 standard defines a special exception in the specification,
and mandates that this particular form of IN predicate shall be equivalent
to "IN ( subselect )", which involves a table subquery and works with more
than 1 row.
This fix implements "IN (( subselect ))", "IN ((( subselect )))" etc
as per the SQL:2003 requirement.
All the details related to the implementation of this change have been
commented in the code, and the relevant sections of the SQL:2003 spec
are given for reference, so they are not repeated here.
Having access to the spec is a requirement to review in depth this patch.
