ALTER VIEW is currently not supported as a prepared statement

ALTER VIEW is currently not supported when called from stored
procedures or functions for related reasons and should also be disabled.
This patch disables these DDL statements and adjusts the appropriate test
cases accordingly.
Additional tests has been added to reflect on the fact that we do support
CREATE/ALTER/DROP TABLE for Prepared Statements (PS), Stored Procedures (SP)
and PS within SP.

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.
Tested by checking the effect of LOW_PRIORITY flag via a

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.

sql/field.h:
Implement a deep copy constructor for create_field
sql/mysql_priv.h:
LEX::key_list and LEX::create_list were moved to LEX::alter_info.
Update declarations to use LEX::alter_info instead of these two
members.
Remove declarations of mysql_add_index, mysql_drop_index.
sql/sql_class.cc:
Implement deep copy constructors.
sql/sql_class.h:
Implement (almost) deep copy constructors for key_part_spec,
Alter_drop, Alter_column, Key, foreign_key.
Replace pair<columns, keys> with an instance of Alter_info in
select_create constructor. We create a new copy of Alter_info
each time we re-execute SELECT .. CREATE prepared statement.
sql/sql_insert.cc:
Adjust to a new signature of create_table_from_items.
sql/sql_lex.cc:
Implement Alter_info::Alter_info that would make a "deep" copy
of all definition lists (keys, columns).
Move is_partition_management() from sql_partition.cc (feature-based
file division is evil).
sql/sql_lex.h:
Move key_list and create_list to class Alter_info. Implement
Alter_info::Alter_info that can be used with PS and SP.
Get rid of Alter_info::clear() which was an attempt to save on
matches and always use Alter_info::reset().
Implement an auxiliary Alter_info::init_for_create_from_alter()
which is used in mysql_alter_table.
sql/sql_list.cc:
Implement a copy constructor of class List that makes a deep copy
of all list nodes.
sql/sql_list.h:
Implement a way to make a deep copy of all list nodes.
sql/sql_parse.cc:
Adjust to new signatures of mysql_create_table, mysql_alter_table,
select_create. Functions mysql_create_index and mysql_drop_index has
become identical after initialization of alter_info was moved to the
parser, and were merged. Flag enable_slow_log was not updated for
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.
sql/sql_yacc.yy:
LEX::key_list and LEX::create_list moved to class Alter_info

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:

Note that, altough tests covering concurrency-related aspects of CREATE TABLE
LIKE behaviour will only be introduced in 5.1, they were run manually for
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.
