In case of outer join and emtpy WHERE conditon
'always true' condition is created for WHERE clasue.
Later in mysql_select() original SELECT_LEX WHERE
condition is overwritten with created cond.
However SELECT_LEX condition is also used as inital
condition in mysql_select()->JOIN::prepare().
On second execution of PS modified SELECT_LEX condition
is taken and it leads to crash.
The fix is to restore original SELECT_LEX condition
(set to NULL if original cond is NULL) in
reinit_stmt_before_use().
HAVING clause is fixed too for safety reason
(no test case as I did not manage to think out
appropriate example).

The problem was that a user could supply supply data in chunks
via the COM_STMT_SEND_LONG_DATA command to prepared statement
parameter other than of type TEXT or BLOB. This posed a problem
since other parameter types aren't setup to handle long data,
which would lead to a crash when attempting to use the supplied
data.
Given that long data can be supplied at any stage of a prepared
statement, coupled with the fact that the type of a parameter
marker might change between consecutive executions, the solution
is to validate at execution time each parameter marker for which
a data stream was provided. If the parameter type is not TEXT or
BLOB (that is, if the type is not able to handle a data stream),
a error is returned.
sql/sql_prepare.cc:
Before converting the parameter data stream, check the type
compatibility.
tests/mysql_client_test.c:

strict aliasing violations.
One somewhat major source of strict-aliasing violations and
related warnings is the SQL_LIST structure. For example,
consider its member function `link_in_list` which takes
a pointer to pointer of type T (any type) as a pointer to
pointer to unsigned char. Dereferencing this pointer, which
is done to reset the next field, violates strict-aliasing
rules and might cause problems for surrounding code that
uses the next field of the object being added to the list.
The solution is to use templates to parametrize the SQL_LIST
structure in order to deference the pointers with compatible
types. As a side bonus, it becomes possible to remove quite
a few casts related to acessing data members of SQL_LIST.

match the type of the elements of the list. Use forward

in pointers anyway.

the type of object that is stored in the list.

The status of memory allocation in the Lex_input_stream (called
from the Parser_state constructor) was not checked which led to
a parser crash in case of the out-of-memory error.
The solution is to introduce new init() member function in
Parser_state and Lex_input_stream so that status of memory
allocation can be returned to the caller.

'CREATE TABLE IF NOT EXISTS ... SELECT' statement were causing 'CREATE
TEMPORARY TABLE ...' to be written to the binary log in row-based
mode (a.k.a. RBR), when there was a temporary table with the same name.
Because the 'CREATE TABLE ... SELECT' statement was executed as
'INSERT ... SELECT' into the temporary table. Since in RBR mode no
other statements related to temporary tables are written into binary log,
this sometimes broke replication.
This patch changes behavior of 'CREATE TABLE [IF NOT EXISTS] ... SELECT ...'.
it ignores existence of temporary table with the
same name as table being created and is interpreted
as attempt to create/insert into base table. This makes behavior of
'CREATE TABLE [IF NOT EXISTS] ... SELECT' consistent with
how ordinary 'CREATE TABLE' and 'CREATE TABLE ... LIKE' behave.
- Moved some code from innodb_plugin to xtradb, to ensure that all tests runs

This is a re-commit of Monty's merge to eliminate an extra commit from
MySQL-5.1.42 that was accidentally included in the merge.
This is a merge of the MySQL 5.1.41 clone-off (clone-5.1.41-build). In
case there are any extra changes done before final MySQL 5.1.41
release, these will need to be merged later before MariaDB 5.1.41
release.
UPDATE + VIEW + SP + MERGE + ALTER
When cleaning up the stored procedure's internal
structures the flag to ignore the errors for
INSERT/UPDATE IGNORE was not cleaned up.
As a result error ignoring was on during name
resolution. And this is an abnormal situation : the
SELECT_LEX flag can be on only during query execution.
Fixed by correctly cleaning up the SELECT_LEX flag
when reusing the SELECT_LEX in a second execution.
Implemented the server infrastructure for the fix:
1. Added a function LEX_STRING *thd_query_string(THD) to return
a LEX_STRING structure instead of char *.
This is the function that must be called in innodb instead of
thd_query()
2. Did some encapsulation in THD : aggregated thd_query and
thd_query_length into a LEX_STRING and made accessor and mutator
methods for easy code updating.
3. Updated the server code to use the new methods where applicable.
* Finished Monty and Jani's merge
* Some InnoDB tests still fail (because it's old xtradb code run against
newer testsuite). They are expected to go after mergning with the latest
xtradb.

This patch fixes a number of GCC warnings about variables used
before initialized. A new macro UNINIT_VAR() is introduced for
use in the variable declaration, and LINT_INIT() usage will be
gradually deprecated. (A workaround is used for g++, pending a
patch for a g++ bug.)
GCC warnings for unused results (attribute warn_unused_result)
for a number of system calls (present at least in later
Ubuntus, where the usual void cast trick doesn't work) are
also fixed.
client/mysqlmanager-pwgen.c:
A fix for warn_unused_result, adding fallback to use of
srand()/rand() if /dev/random cannot be used. Also actually
adds calls to rand() in the second branch so that it actually
creates a random password.

build)
The crash was caused by freeing the internal parser stack during the parser
execution.
This occured only for complex stored procedures, after reallocating the parser
stack using my_yyoverflow(), with the following C call stack:
- MYSQLparse()
- any rule calling sp_head::restore_lex()
- lex_end()
- x_free(lex->yacc_yyss), xfree(lex->yacc_yyvs)
The root cause is the implementation of stored procedures, which breaks the
assumption from 4.1 that there is only one LEX structure per parser call.
The solution is to separate the LEX structure into:
- attributes that represent a statement (the current LEX structure),
- attributes that relate to the syntax parser itself (Yacc_state),
so that parsing multiple statements in stored programs can create multiple
LEX structures while not changing the unique Yacc_state.
Now, Yacc_state and the existing Lex_input_stream are aggregated into
Parser_state, a structure that represent the complete state of the (Lexical +
Syntax) parser.

Bug#31210: INSERT DELAYED crashes server when used on partitioned tables
Changed to the newly added error message
PREPARE", review fixes:
- make the patch follow the specification of WL#4166 and remove
the new error that was originally introduced.
Now the client never gets an error from reprepare, unless it failed.
I.e. even if the statement at hand returns a completely different
result set, this is not considered a server error.
The C API library, that can not handle this situation, was modified to
return a client error.
Added additional test coverage.
include/errmsg.h:
Add a new client side error: now when we automatically
reprepare a statement, the new result set may contain a different
number of columns.
include/mysql_com.h:
Add a new server status to be sent to the client if the
number of columns in the result set is different.
libmysql/errmsg.c:
Add a new error message.
libmysql/libmysql.c:
Make the client library robust against a result set that
contains a different number of columns from prepare time.
Previously that could never happen, and we simply had an assert.
That means in particular that all clients are advised to upgrade
with transition to 5.1, if they are using prepared statements C API.
Make mysql_stmt_store_result() and mysql_stmt_execute() robust against
"broken" statement handles (those that have an error).
sql/sql_parse.cc:
Clear transient server status flags at start of statement more
systematically.
sql/share/errmsg.txt:
Remove an error that is unused and is not part of any public release.
sql/sql_prepare.cc:
Instead of returning an error in case the number of result set columns
has changed, simply update the client in server status.
That will allow modern clients automatically recover from an error.
tests/mysql_client_test.c:
Add additional coverage to the cases when the number of result
set columns changed as a result of reprepare.
Cover conversion and truncation of result set columns.

Add metadata validation to ~20 more SQL commands. Make sure that
these commands actually work in ps-protocol, since until now they
were enabled, but not carefully tested.
Fixes the ml003 bug found by Matthias during internal testing of the
patch.
mysql-test/r/ps_ddl.result:
Update test results (WL#4165)
mysql-test/t/ps_ddl.test:
Cover with tests metadata validation of 26 SQL statements.
sql/mysql_priv.h:
Fix the name in the comment.
sql/sp_head.cc:
Changed the way the observer is removed in case of stored procedures
to support validation prepare stmt from "call p1(<expr>)": whereas
tables used in the expression must be validated, substatements
of p1 must not.
The previous scheme used to silence the observer only in stored
functions and triggers.
sql/sql_class.cc:
Now the observer is silenced in sp_head::execute(). Remove it from
Sub_statement_state.
sql/sql_class.h:
Now the observer is silenced in sp_head::execute(). Remove it from
Sub_statement_state.
sql/sql_parse.cc:
Add CF_REEXECUTION_FRAGILE to 20 more SQLCOMs that need it.
sql/sql_prepare.cc:
Add metadata validation to ~20 new SQLCOMs that need it.
Fix memory leaks with expressions used in SHOW DATABASES and CALL
(and prepared statements).
We need to fix all expressions at prepare, since if these expressions
use subqueries, there are one-time transformations of the parse
tree that must be done at prepare.
List of fixed commands includes: SHOW TABLES, SHOW DATABASES,
SHOW TRIGGERS, SHOW EVENTS, SHOW OPEN TABLES,SHOW KEYS, SHOW FIELDS,
SHOW COLLATIONS, SHOW CHARSETS, SHOW VARIABLES, SHOW TATUS, SHOW TABLE
STATUS, SHOW PROCEDURE STATUS, SHOW FUNCTION STATUS, CALL.
Add comment to set_parameters().
sql/table.h:
Update comments.
WL#4165 Prepared statements: validation
WL#4166 Prepared statements: automatic re-prepare
Fixes
Bug#27430 Crash in subquery code when in PS and table DDL changed after PREPARE
Bug#27690 Re-execution of prepared statement after table was replaced with a view crashes
Bug#27420 A combination of PS and view operations cause error + assertion on shutdown
The basic idea of the patch is to keep track of table metadata between
prepared statement prepare and execute. If some table used in the statement
has changed, the prepared statement is re-prepared before execution.
See WL#4165 and WL#4166 contents and comments in the code for details
of the implementation.
include/my_global.h:
Remove 'register' keyword to avoid warnings when swapping large structures
that don't fit into a register. Any modern compiler is capable of placing
a variable in a register when that would benefit performance.
mysql-test/r/ps_1general.result:
Update test results: since now we re-prepare automatically,
more correct results are produced in prepare-ddl-execute scenario.
mysql-test/r/query_cache_merge.result:
Ensure that the table definition cache is large enough for
the test to pass in --ps-protocol
mysql-test/r/trigger.result:
Update test results to reflect automatic statement reprepare.
mysql-test/t/disabled.def:
Enable ps_ddl.test, which now passes.
mysql-test/t/ps_1general.test:
Since now we re-execute prepared statements after DDL successfully,
change the test to produce repeatable results. Remove expectancy of
an error in one place where now we automatically reprepare the prepared
statement.
mysql-test/t/query_cache_merge.test:
Ensure the table definition cache is large enough for the test to pass
in --ps-protocol
mysql-test/t/trigger.test:
Sinc
sql/item.cc:
Implement Item_param "copy" functionality, used at re-prepare of
a prepared statement.
We copy the type of the original parameter, and move the assigned value,
if any. Sic, the value is "moved", since it can be quite big --
e.g. in case we deal with a LONG DATA parameter.
It's essential to move the value from the old parameter since
at the time of re-prepare the client packet with the necessary information
may be not available.
sql/item.h:
Declare a new method used for reprepare.
sql/my_decimal.h:
Implement "swap()" functionality of class my_decimal to be
able to easily swap two decimal values.
sql/mysql_priv.h:
Declare enum_metadata_type.
sql/mysqld.cc:
Implement a status variable for the number of reprepared statements.
sql/sql_base.cc:
Implement metadata version validation.
sql/share/errmsg.txt:
Add two new error messages: ER_NEED_REPREPARE and ER_PS_REBIND.
The first error (theoretically) never reaches the user.
It is issued by the metadata validation framework when a metadata version
has changed between prepare and execute. Later on it's intercepted
and the statement is automatically re-prepared. Only if the error
has occurred repeatedly MAX_REPREPARE_ATTEMTS (3) times do we
return it to the user.
The second error is issued when after re-prepare we discover
that the metadata we sent over to the client using the binary
protocol differs drammatically from the new result set metadata
that the reprepared statement produces (e.g. number of result
set columns is different).
sql/sql_class.cc:
Implement metadata version validation framework.
sql/sql_class.h:
Declarations for metadata version validation framework.
sql/sql_parse.cc:
Mark commands for which we must invalidate and reprepare a prepared
statement when metadata has changed.
sql/sql_prepare.cc:
Implement WL#4165 and WL#4166 (limited support of metadata validation
and re-prepare).
sql/table.h:
Implement metadata validation.
tests/mysql_client_test.c:
Add a test case for WL#4166
