1003: Incorrect table name
in multi-table DELETE the set of tables to delete from actually
references then tables in the other list, e.g:
DELETE alias_of_t1 FROM t1 alias_of_t1 WHERE ....
is a valid statement.
So we must turn off table name syntactical validity check for alias_of_t1
because it's not a table name (even if it looks like one).
In order to do that we add a special flag (TL_OPTION_ALIAS) to
disable the name checking for the aliases in multi-table DELETE.

erroneous check
Problem: Actually there were two problems in the server code. The check
for SQLCOM_FLUSH in SF/Triggers were not according to the existing
architecture which uses sp_get_flags_for_command() from sp_head.cc .
This function was also missing a check for SQLCOM_FLUSH which has a
problem combined with prelocking. This changeset fixes both of these
deficiencies as well as the erroneous check in
sp_head::is_not_allowed_in_function() which was a copy&paste error.
mysql-test/r/sp-error.result:

mysql-test/r/trigger.result:

mysql-test/t/sp-error.test:
FLUSH can create a problem with prelocking, hence it's disabled.
There is a better way to check this than a check in the parser.
Now we use sp_get_flags_for_command() and the error returned is
different.
mysql-test/t/trigger.test:
FLUSH can create a problem with prelocking, hence it's disabled.
There is a better way to check this than a check in the parser.
Now we use sp_get_flags_for_command() and the error returned is
different.
sql/sp_head.cc:
FLUSH and RESET are not allowed inside a SF/Trigger.
Because they don't imply a COMMIT sp_head::HAS_COMMIT_OR_ROLLBACK
cannot be used. Two new flags were introduced for that reason.
sql/sp_head.h:
Don't check m_type as this check is erroneous. This is probably
a copy and paste error when moving code from somewhere else. Another
fact which supports this was prefixing the enum value with the name
of class sp_head.
Adding two new flags HAS_SQLCOM_RESET and HAS_SQLCOM_FLUSH. The values
are 2048 and 4096 because in the 5.1 branch there are already new flags
which are with values up-to 1024.
sql/sql_parse.cc:
FLUSH can cause a problem with prelocking in SF/Trigger and
therefore is already disabled. RESET is also disabled because
is handled by the same code as FLUSH. We won't allow RESET inside
SF/Trigger at that stage without thorough analysis. The check for
them is already done in the parser by calling
is_not_allowed_in_function()
sql/sql_yacc.yy:
By listing SQLCOM_FLUSH as command which implies COMMIT
in sp_get_flags_for_command() the check in sql_yacc.yy is
obsolete.

User name (host name) has limit on length. The server code relies on these
limits when storing the names. The problem was that sometimes these limits
were not checked properly, so that could lead to buffer overflow.
The fix is to check length of user/host name in parser and if string is too
long, throw an error.

"real" table fails in JOINs".
This is a regression caused by the fix for Bug 18444.
This fix removed the assignment of empty_c_string to table->db performed
in add_table_to_list, as neither me nor anyone else knew what it was
there for. Now we know it and it's covered with tests: the only case
when a table database name can be empty is when the table is a derived
table. The fix puts the assignment back but makes it a bit more explicit.
Additionally, finally drop sp.result.orig which was checked in by mistake.
BitKeeper/deleted/.del-sp.result.orig:

mysql-test/r/derived.result:
Updated result file.
mysql-test/r/sp.result:

(See Bug#21148 for details)

Add a test case for Bug#21002 "Derived table not selecting from a "real"
table fails in JOINs"
sql/sp.cc:
Make empty_c_string globally accessible.

Add a comment for the constructor of Table_ident which is
used for derived tables. Make sure this constructor also initializes
the database name, not only the table name.

Don't call check_db_name for empty database.
Currently the only case when a table database name can be empty
is when the table is a derived table.
Report the right error if the database name is wrong (ER_WRONG_DB_NAME,
not ER_WRONG_TABLE_NAME).

context.
Routine arguments were evaluated in the security context of the routine
itself, not in the caller's context.
The bug is fixed the following way:
- Item_func_sp::find_and_check_access() has been split into two
functions: Item_func_sp::find_and_check_access() itself only
finds the function and check that the caller have EXECUTE privilege
on it. New function set_routine_security_ctx() changes security
context for SUID routines and checks that definer have EXECUTE
privilege too.
- new function sp_head::execute_trigger() is called from
Table_triggers_list::process_triggers() instead of
sp_head::execute_function(), and is effectively just as the
sp_head::execute_function() is, with all non-trigger related code
removed, and added trigger-specific security context switch.
- call to Item_func_sp::find_and_check_access() stays outside
of sp_head::execute_function(), and there is a code in
sql_parse.cc before the call to sp_head::execute_procedure() that
checks that the caller have EXECUTE privilege, but both
sp_head::execute_function() and sp_head::execute_procedure() call
set_routine_security_ctx() after evaluating their parameters,
and restore the context after the body is executed.

run at startup"
The server returned an error when trying to execute init-file with a
stored procedure that could return multiple result sets to the client.
A stored procedure can return multiple result sets if it contains
PREPARE, SELECT, SHOW and similar statements.
The fix is to set client_capabilites|=CLIENT_MULTI_RESULTS in
sql_parse.cc:handle_bootstrap(). There is no "client" really, so
nothing is ever sent. This makes init-file feature behave consistently:
the prepared statements that can be called directly in the init-file
can be used in a stored procedure too.

NDB table".
SQL-layer was not marking fields which were used in triggers as such. As
result these fields were not always properly retrieved/stored by handler
layer. So one might got wrong values or lost changes in triggers for NDB,
Federated and possibly InnoDB tables.
This fix solves the problem by marking fields used in triggers
appropriately.
Also this patch contains the following cleanup of ha_ndbcluster code:
We no longer rely on reading LEX::sql_command value in handler in order
to determine if we can enable optimization which allows us to handle REPLACE
statement in more efficient way by doing replaces directly in write_row()
method without reporting error to SQL-layer.
Instead we rely on SQL-layer informing us whether this optimization
applicable by calling handler::extra() method with
HA_EXTRA_WRITE_CAN_REPLACE flag.
As result we no longer apply this optimzation in cases when it should not
be used (e.g. if we have on delete triggers on table) and use in some
additional cases when it is applicable (e.g. for LOAD DATA REPLACE).
Finally this patch includes fix for bug#20728 "REPLACE does not work
correctly for NDB table with PK and unique index".
This was yet another problem which was caused by improper field mark-up.
During row replacement fields which weren't explicity used in REPLACE
statement were not marked as fields to be saved (updated) so they have
retained values from old row version. The fix is to mark all table
fields as set for REPLACE statement. Note that in 5.1 we already solve
this problem by notifying handler that it should save values from all
fields only in case when real replacement happens.
include/my_base.h:
Added HA_EXTRA_WRITE_CAN_REPLACE, HA_EXTRA_WRITE_CANNOT_REPLACE - new
parameters for ha_extra() method. We use them to inform handler that
write_row() which tries to insert new row into the table and encounters
some already existing row with same primary/unique key can replace old
row with new row instead of reporting error.
mysql-test/r/federated.result:
Additional test for bug#18437 "Wrong values inserted with a before update
trigger on NDB table".
mysql-test/r/ndb_replace.result:

mysql-test/t/federated.test:

Item_trigger_field::setup_field():

sql/mysql_priv.h:

Added declaration of mark_fields_used_by_triggers_for_insert_stmt() function.
sql/sql_delete.cc:
Mark fields which are used by ON DELETE triggers so handler will retrieve
values for these fields.
sql/sql_insert.cc:
Explicitly inform handler that we are doing REPLACE (using ha_extra() method)
in cases when it can promote insert operation done by write_row() to replace.
Also when we do REPLACE we want to store values for all columns so we should
inform handler about it.
Finally we should mark fields used by ON UPDATE/ON DELETE triggers as such
so handler can properly retrieve/restore values in these fields during
execution of REPLACE and INSERT ... ON DUPLICATE KEY UPDATE statements.
sql/sql_load.cc:
Explicitly inform handler that we are doing LOAD DATA REPLACE (using
ha_extra() method) in cases when it can promote insert operation done by
write_row() to replace.
Also when we do replace we want to save (replace) values for all columns
so we should inform handler about it.
Finally to properly execute LOAD DATA for table with triggers we should
mark fields used by ON INSERT triggers as such so handler can properly
store values for these fields.
sql/sql_parse.cc:
mysql_alter_table() function no longer takes handle_duplicates argument.
sql/sql_table.cc:
Got rid of handle_duplicates argument in mysql_alter_table() and
copy_data_between_tables() functions. These functions were always
called with handle_duplicates == DUP_ERROR and thus contained dead
(and probably incorrect) code.
sql/sql_trigger.cc:

fields read/set by triggers as such so handlers will be able properly
retrieve/store values in these fields.
sql/sql_trigger.h:
Table_triggers_list:
Added mark_fields_used() method which is used to mark fields read/set by

in these fields. To implement this method added 'trigger_fields' member
which is array of lists linking items for all fields used in triggers
grouped by event and action time.
sql/sql_update.cc:
Mark fields which are used by ON UPDATE triggers so handler will retrieve
and save values for these fields.

Bug#19022 "Memory bug when switching db during trigger execution"
Bug#17199 "Problem when view calls function from another database."
Bug#18444 "Fully qualified stored function names don't work correctly in
SELECT statements"
Documentation note: this patch introduces a change in behaviour of prepared
statements.
This patch adds a few new invariants with regard to how THD::db should
be used. These invariants should be preserved in future:
- one should never refer to THD::db by pointer and always make a deep copy
(strmake, strdup)
- one should never compare two databases by pointer, but use strncmp or
my_strncasecmp
- TABLE_LIST object table->db should be always initialized in the parser or
by creator of the object.
For prepared statements it means that if the current database is changed
after a statement is prepared, the database that was current at prepare
remains active. This also means that you can not prepare a statement that
implicitly refers to the current database if the latter is not set.
This is not documented, and therefore needs documentation. This is NOT a
change in behavior for almost all SQL statements except:
- ALTER TABLE t1 RENAME t2
- OPTIMIZE TABLE t1
- ANALYZE TABLE t1
- TRUNCATE TABLE t1 --
until this patch t1 or t2 could be evaluated at the first execution of
prepared statement.
CURRENT_DATABASE() still works OK and is evaluated at every execution
of prepared statement.
Note, that in stored routines this is not an issue as the default
database is the database of the stored procedure and "use" statement
is prohibited in stored routines.
This patch makes obsolete the use of check_db_used (it was never used in the
old code too) and all other places that check for table->db and assign it
from THD::db if it's NULL, except the parser.
How this patch was created: THD::{db,db_length} were replaced with a
LEX_STRING, THD::db. All the places that refer to THD::{db,db_length} were
manually checked and:
- if the place uses thd->db by pointer, it was fixed to make a deep copy
- if a place compared two db pointers, it was fixed to compare them by value
(via strcmp/my_strcasecmp, whatever was approproate)
Then this intermediate patch was used to write a smaller patch that does the
same thing but without a rename.
TODO in 5.1:
- remove check_db_used
- deploy THD::set_db in mysql_change_db
See also comments to individual files.
mysql-test/r/create.result:
Modify the result file: a database can never be NULL.
mysql-test/r/ps.result:
Update test results (Bug#17199 et al)
mysql-test/r/sp.result:
Update test results (Bug#17199 et al)
mysql-test/t/create.test:
Update the id of the returned error.
mysql-test/t/ps.test:
Add test coverage for prepared statements and current database. In scope of
work on Bug#17199 "Problem when view calls function from another database."
mysql-test/t/sp.test:
Add a test case for Bug#17199 "Problem when view calls function from another
database." and Bug#18444 "Fully qualified stored function names don't work
correctly in SELECT statements". Test a complementary problem.
sql/item_strfunc.cc:
Touch the code that reads thd->db (cleanup).
sql/log_event.cc:
While we are at it, replace direct access to thd->db with a method.
Should simplify future conversion of THD::db to LEX_STRING.
sql/slave.cc:
While we are at it, replace direct access to thd->db with a method.
Should simplify future conversion of THD::db to LEX_STRING.
sql/slave.h:
Remove a declaration for a method that is used only in one module.
sql/sp.cc:
Rewrite sp_use_new_db: this is a cleanup that I needed in order to understand
this function and ensure that it has no bugs.
sql/sp.h:
Add a new declaration for sp_use_new_db (uses LEX_STRINGs) and a comment.
sql/sp_head.cc:
- drop sp_name_current_db_new - a creator of sp_name class that was used
when sp_name was created for an identifier without an explicitly initialized
database. Now we pass thd->db to constructor of sp_name right in the
parser.
- rewrite sp_head::init_strings: name->m_db is always set now
- use the new variant of sp_use_new_db
- we don't need to update thd->db with SP MEM_ROOT pointer anymore when
parsing a stored procedure, as noone will refer to it (yes!)
sql/sp_head.h:
- remove unneded methods and members
sql/sql_class.h:
- introduce 3 THD methods to work with THD::db:
.set_db to assign the current database
.reset_db to reset the current database (temporarily) or set it to NULL
.opt_copy_db_to - to deep-copy thd->db to a pointer if it's not NULL
sql/sql_db.cc:
While we are at it, replace direct access to thd->db with a method.
Should simplify future conversion of THD::db to LEX_STRING.
sql/sql_insert.cc:
- replace checks with asserts: table_list->db must be always set in the parser.
sql/sql_lex.h:
- add a comment
sql/sql_parse.cc:
- implement the invariant described in the changeset comment.
- remove juggling with lex->sphead in SQLCOM_CREATE_PROCEDURE:
now db_load_routine uses its own LEX object and doesn't damage the main
LEX.
- add DBUG_ASSERT(0) to unused "check_db_used"
sql/sql_table.cc:
- replace a check with an assert (table_ident->db)
sql/sql_trigger.cc:
While we are at it, replace direct access to thd->db with a method.
Should simplify future conversion of THD::db to LEX_STRING.
sql/sql_udf.cc:
- use thd->set_db instead of direct modification of to thd->db
sql/sql_view.cc:
- replace a check with an assert (view->db)
sql/sql_yacc.yy:
- make sure that we always copy table->db or name->db or ident->db or
select_lex->db from thd->db if the former is not set. If thd->db
is not set but is accessed, return an error.
sql/tztime.cc:
- be nice, never copy thd->db by pointer.
Addendum fixes after changing the condition variable
for the global read lock.
The stress test suite revealed some deadlocks. Some were
related to the new condition variable (COND_global_read_lock)
and some were general problems with the global read lock.
It is now necessary to signal COND_global_read_lock whenever
COND_refresh is signalled.
We need to wait for the release of a global read lock if one
is set before every operation that requires a write lock.
But we must not wait if we have locked tables by LOCK TABLES.
After setting a global read lock a thread waits until all
write locks are released.

The function check_one_table_access() called to check access to tables in
SELECT/INSERT/UPDATE was doing additional checks/modifications that don't hold
in the context of setup_tables_and_check_access().
That's why the check_one_table() was split into two : the functionality needed by
setup_tables_and_check_access() into check_single_table_access() and the rest of
the functionality stays in check_one_table_access() that is made to call the new
check_single_table_access() function.

- check_one_table_access() split into two : check_single_table_access() to

check_single_table_access() and checks also the tables belonging to sub selects

function crashes server".
Attempts to execute prepared multi-delete statement which involved trigger or
stored function caused server crashes (the same happened for such statements
included in stored procedures in cases when one tried to execute them more
than once).
The problem was caused by yet another incorrect usage of check_table_access()
routine (the latter assumes that table list which it gets as argument
corresponds to value LEX::query_tables_own_last). We solve this problem by
juggling with LEX::query_tables_own_last value when we call
check_table_access() for LEX::auxilliary_table_list (better solution is too
intrusive and should be done in 5.1).
mysql-test/r/sp-prelocking.result:
Added test for bug#19634 "Re-execution of multi-delete which involve trigger/
stored function crashes server".
mysql-test/t/sp-prelocking.test:
Added test for bug#19634 "Re-execution of multi-delete which involve trigger/
stored function crashes server".
sql/sql_parse.cc:
To call safely check_table_access() for LEX::auxilliary_table_list we have
to juggle with LEX::query_tables_own_last value.
there was two problems about charsets in embedded server
1. mysys/charset.c - defined there default_charset_info variable is
modified by both server and client code (particularly when
--default-charset option is handled)
In embedded server we get two codelines modifying one variable.
I created separate default_client_charset_info for client code
2. mysql->charset and mysql->options.charset initialization isn't
properly done for embedded server - necessary calls added
include/sql_common.h:
client charset info default declared
libmysqld/lib_sql.cc:
thd_init_client_charset calls added
libmysqld/libmysqld.c:
check_embedded_connection moved to client.c to avoid code duplication
sql-common/client.c:
charset initialization moved to mysql_init_character_set to
be used in embedded server
sql/sql_parse.cc:
thread client charset initialization moved to thd_init_client_charset
to avoid code duplication
There was an incomplete reset of the name resolution context, that caused
INSERT ... SELECT ... JOIN statements to resolve not by joint row type calculated
for the join.
Removed the redundant re-initialization of the context, because
mysql_insert_select_prepare() now correctly saves/restores the context.

correctly saves/restores the context.
There was a wrong determination of the DB name (witch is
not always the one in TABLE_LIST because derived tables
may be calculated using temp tables that have their db name
set to "").
The fix determines the database name according to the type
of table reference, and calls the function check_access()
with the correct db name so the correct set of grants is found.
mysql-test/r/view_grant.result:
testsuite for the bug
mysql-test/t/view_grant.test:
testsuite for the bug
sql/sql_parse.cc:
correct determination of the db name.
There actually was 3 different problems -
hash_user_connections wasn't cleaned
one strdupped database name wasn't freed
and stmt->mem_root wasn't cleaned as it was
replased with mysql->field_alloc for result
For the last one - i made the library using stmt's
fields to store result if it's the case.
include/mysql.h:
statement pointer added to the advanced_command to be checked in
embedded server
include/sql_common.h:
stmt added to the cli_advanced_command interface
libmysql/libmysql.c:
stmt pointer now sent to advanced_command
libmysqld/embedded_priv.h:
it's enough to send database name to check_embedded_connection
libmysqld/lib_sql.cc:
Now we store result directly in the MYSQL_STMT structure to
avoid extra copying
libmysqld/libmysqld.c:
it's enough to only send database pointer to check_embedded_connection
sql-common/client.c:
stmt fake attribute added to cli_advanced_command
sql/sql_parse.cc:
hash_user_connections isn't used if no access checks compiled
