kostja@dipika.(none) d1f9376229 Tentative implementation of 
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.

################ The basic functions ################
# 1. PREPARE stmt_name FROM <preparable statement>;
# <preparable statement> ::=
# 'literal_stmt' |
# @variable_ref_stmt.
# The statement may contain question marks as placeholders for parameters.
#
# Bind a statement name to a string containing a SQL statement and
# send it to the server. The server will parse the statement and
# reply with "Query Ok" or an error message.
#
PREPARE stmt FROM ' select * from t1 where a = ? ' ;
# 2. EXECUTE stmt_name [USING @var [, @var ]];
# Current values of supplied variables are used as parameters.
#
# Send the server the order to execute the statement and supply values
# for the input parameters needed.
# If no error occurs the server reply will be identical to the reply for
# the query used in PREPARE with question marks replaced with values of
# the input variables.
#
SET @var= 2 ;
EXECUTE stmt USING @var ;
# The non prepared statement with the same server reply would be:
select * from t1 where a = @var ;
# 3. DEALLOCATE PREPARE stmt_name;
#
# Send the server the order to drop the parse informations.
# The server will reply with "Query Ok" or an error message.

##### RULES OF THUMB TO PRESERVE THE SYSTEMATICS OF THE PS TEST CASES #####
#
# 0. You don't have the time to
# - read and pay attention to these rules of thumb
# - accept that QA may move your test case to a different place
# (I will not change your code!!) .
# Please append your test case to
# t/ps.test
#
# 1. You have more time and want to get as much value from you test case as
# possible. Please try to make the following decisions:
#
# Will the execution or result of the sub test case depend on the
# properties of a storage engine ?
#
# NO --> alter t/ps_1general.test (Example: Command with syntax error)
# If you need a table, please try to use
# t1 - very simple table
# t9 - table with nearly all available column types
# whenever possible.
#
# The structure and the content of these tables can be found in
# include/ps_create.inc CREATE TABLE ...
# include/ps_renew.inc DELETE all rows and INSERT some rows
#
# Both tables are managed by the same storage engine.
# The type of the storage engine is stored in the variable
# '$type' . In ps_1general.test $type is set to 'MYISAM'.
#
# Please feel free to source ps_create.inc or ps_renew.inc
# whenever you think it helps. But please restore the original
# state of these tables after your tests, because the following
# statements may depend on it.
#
# YES
# |
# |
# Is it possible to apply the sub test case to all table types ?
# YES --> alter include/ps_query.inc (for SELECTs)
# include/ps_modify.inc (for INSERT/UPDATE/DELETE)
# include/ps_modify1.inc (also for INSERT/UPDATE/DELETE,
# but t/ps_5merge.test will not source that file)
# Please try to find an appropriate place within the file.
# It would be nice if we have some systematics in the
# order of the sub test cases (if possible).
#
# Please be aware, that
# include: ps_query.inc, ps_modify.inc, ps_modify1.inc
# will be sourced by several test case files stored within the
# subdirectory 't'. So every change here will affect several test
# cases.
#
# NO
# |
# |
# Append the sub test case to the appropriate
# ps_<number><table type>.test .
#
# 2. The current structure of the PS tests
#
# t/ps_1general.test Check of basic PS features, SHOW commands and DDL
# The tests should not depend on the table type.
#
# t/ps_2myisam Check of PS on tables of type MYISAM .
# t/ps_3innodb Check of PS on tables of type InnoDB .
# ...
# t/ps_6bdb Check of PS on tables of type BDB .
# All storage engine related tests use the variable $type to hold the
# name of the storage engine.
#
# include/ps_query.inc test cases with SELECT/...
# These test cases should not modify the content or
# the structure (DROP/ALTER..) of the tables
# 't1' and 't9'.
# include/ps_modify.inc test cases with INSERT/UPDATE/...
# These test cases should not modify the structure
# (DROP/ALTER..) of the tables
# 't1' and 't9'.
# These two test sequences will be applied to all table types .
#
# include/ps_modify1.inc test cases with INSERT/UPDATE/...
# This test sequences will be applied to all table types
# except MERGE tables.
#
# include/ps_create.inc DROP and CREATE of the tables
# 't1' and 't9' .
# include/ps_renew.inc DELETE all rows and INSERT some rows, that means
# recreate the original content of these tables.
# Please do not alter the commands concerning these two tables.
#
# Please feel free and encouraged to exploit the current code sharing
# mechanism of the 'ps_<number><table type>' test cases. It is an convenient
# way to check all storage engines.
#
# Thank you for reading these rules of thumb.
#
# Matthias
# End of 4.1 tests
