Bug#989: If DROP TABLE while there's an active transaction, wrong binlog order
WL#4284: Transactional DDL locking
Currently the MySQL server does not keep metadata locks on
schema objects for the duration of a transaction, thus failing
to guarantee the integrity of the schema objects being used
during the transaction and to protect then from concurrent
DDL operations. This also poses a problem for replication as
a DDL operation might be replicated even thought there are
active transactions using the object being modified.
The solution is to defer the release of metadata locks until
a active transaction is either committed or rolled back. This
prevents other statements from modifying the table for the
entire duration of the transaction. This provides commitment
ordering for guaranteeing serializability across multiple
transactions.
- Incompatible change:
If MySQL's metadata locking system encounters a lock conflict,
the usual schema is to use the try and back-off technique to
avoid deadlocks -- this schema consists in releasing all locks
and trying to acquire them all in one go.
But in a transactional context this algorithm can't be utilized
as its not possible to release locks acquired during the course
of the transaction without breaking the transaction commitments.
To avoid deadlocks in this case, the ER_LOCK_DEADLOCK will be
returned if a lock conflict is encountered during a transaction.
Let's consider an example:
A transaction has two statements that modify table t1, then table
t2, and then commits. The first statement of the transaction will
acquire a shared metadata lock on table t1, and it will be kept
utill COMMIT to ensure serializability.
At the moment when the second statement attempts to acquire a
shared metadata lock on t2, a concurrent ALTER or DROP statement
might have locked t2 exclusively. The prescription of the current
locking protocol is that the acquirer of the shared lock backs off
-- gives up all his current locks and retries. This implies that
the entire multi-statement transaction has to be rolled back.
- Incompatible change:
FLUSH commands such as FLUSH PRIVILEGES and FLUSH TABLES WITH READ
LOCK won't cause locked tables to be implicitly unlocked anymore.

sql/ha_ndbcluster_binlog.cc:
Backport bits of changes of ha_ndbcluster_binlog.cc
from 6.0, to fix the failing binlog test suite with
WL#4284. WL#4284 implementation does not work
with 5.1 implementation of ndbcluster binlog index.
sql/log_event.cc:

Release metadata locks on commit (WL#4284).
sql/rpl_rli.cc:
Remove assert made meaningless, metadata locks are released
at the end of the transaction.
sql/set_var.cc:
Close tables and release locks if autocommit mode is set.
sql/slave.cc:
Release metadata locks after a rollback.
sql/sql_acl.cc:
Don't implicitly unlock locked tables. Issue a implicit commit
at the end and unlock tables.
sql/sql_base.cc:
Defer the release of metadata locks when closing tables
if not required to.
Issue a deadlock error if the locking protocol requires
that a transaction re-acquire its locks.
Release metadata locks when closing tables for reopen.
sql/sql_class.cc:
Release metadata locks if the thread is killed.
sql/sql_parse.cc:
Release metadata locks after implicitly committing a active
transaction, or after explicit commits or rollbacks.
sql/sql_plugin.cc:
Allocate MDL request on the stack as the use of the table
is contained within the function. It will be removed from
the context once close_thread_tables is called at the end
of the function.
sql/sql_prepare.cc:
The problem is that the prepare phase of the CREATE TABLE
statement takes a exclusive metadata lock lock and this can
cause a self-deadlock the thread already holds a shared lock
on the table being that should be created.
The solution is to make the prepare phase take a shared
metadata lock when preparing a CREATE TABLE statement. The
execution of the statement will still acquire a exclusive
lock, but won't cause any problem as it issues a implicit
commit.
After some discussions with stakeholders it has been decided that
metadata locks acquired during a PREPARE statement must be released
once the statement is prepared even if it is prepared within a multi
statement transaction.
sql/sql_servers.cc:
Don't implicitly unlock locked tables. Issue a implicit commit
at the end and unlock tables.
sql/sql_table.cc:
Close table and release metadata locks after a admin operation.
sql/table.h:
The problem is that the prepare phase of the CREATE TABLE
statement takes a exclusive metadata lock lock and this can
cause a self-deadlock the thread already holds a shared lock
on the table being that should be created.
The solution is to make the prepare phase take a shared
metadata lock when preparing a CREATE TABLE statement. The
execution of the statement will still acquire a exclusive
lock, but won't cause any problem as it issues a implicit
commit.
sql/transaction.cc:
Release metadata locks after the implicitly committed due
to a new transaction being started. Also, release metadata
locks acquired after a savepoint if the transaction is rolled
back to the save point.
The problem is that in some cases transaction-long metadata locks
could be released before the transaction was committed. This could
happen when a active transaction was ended by a "START TRANSACTION"
or "BEGIN" statement, in which case the metadata locks would be
released before the actual commit of the active transaction.
The solution is to defer the release of metadata locks to after the
transaction has been implicitly committed. No test case is provided
as the effort to provide one is too disproportional to the size of
the fix.

message:
WL#4284: Transactional DDL locking
SQL statements' effect on transactions.
Currently the MySQL server and its storage engines are not
capable of rolling back operations that define or modify data
structures (also known as DDL statements) or operations that
alter any of the system tables (the mysql database). Allowing
these group of statements to participate in transactions
is unfeasible at this time (since rollback has no effect
whatsoever on them) and goes against the design of our metadata
locking subsystem.
The solution is to issue implicit commits before and after
those statements execution. This effectively confines each of
those statements to its own special transaction and ensures
that metadata locks taken during this special transaction
are not leaked into posterior statements/transactions.
mysql-test/include/commit.inc:
Alter table rename was not committing the normal transaction at the
end of its execution, and as a consequence, the commit was being
issued in the next DDL command (rename table) that happened to end
the active transaction. Other changes are to take into account the
implicit commits issued before and after the DDL command execution.
mysql-test/include/implicit_commit_helper.inc:
Add auxiliary test that shows if a statement issued a
implicit commit.
mysql-test/r/commit_1innodb.result:
Update test case result.
mysql-test/r/implicit_commit.result:
Test implicit commit behavior of some SQL commands.
mysql-test/t/implicit_commit.test:

sql/events.cc:

sql/mysql_priv.h:
Add flags array for server commands and remove historical
left over.
sql/sql_class.h:
Add flags to control when to issue implicit commits before and
after a command execution.
sql/sql_delete.cc:
A implicit commit is issued at the end of truncate
statements.
sql/sql_parse.cc:
Mark commands that need implicit commits before and
after their executions. The implicit commits of the
statement and the normal transaction are now issued
regardless of the user access privileges.
sql/sql_table.cc:
A implicit commit is now issued before admin commands.
tests/mysql_client_test.c:
Test that COM_REFRESH issues a implicit commit.

Bug#36004 mysql_stmt_prepare resets the list of warnings
Although the manual says that "the list of messages is reset
for each new statement that uses a table", the list of messages
is being unconditionally reset for prepare commands.
The solution is to enforce that the prepare command will only
reset the message list if the statement being prepared uses
a table or a warning is pushed.

Fix link error with intel compiler (icl
defines of special label for exception handler)
The reason for the bug is that mysqtest as well as other client tools
running in test suite (mysqlbinlog, mysqldump) will first try to connect
whatever database has created shared memory with default base name
"MySQL" and use this. (Same effect could be seen on Unix if mtr would
not care to calculate "port" and "socket" parameter).
The fix ensures that all client tools and running in mtr use unique
per-database shared memory base parameters, so there is no possibility
to clash with already installed one. We use socket name for shared memory
base (it's known to be unique). This shared-memory-base is written to the
MTR config file to the [client] and [mysqld] sections. Fix made also made
sure all client tools understand and correctly handle --shared-memory-base.
Prior to this patch it was not the case for mysqltest, mysqlbinlog and
mysql_client_test.
All new connections done from mtr scripts via connect() will by default
set shared-memory-base. And finally, there is a possibility to force
shared memory or pipe connection and overwrite shared memory/pipe base name
from within mtr scripts via optional PIPE or SHM modifier. This functionality
was manually backported from 6.0

2630.29.28, 2630.31.1, 2630.28.13, 2630.28.10, 2617.23.14 and
some other minor revisions.
This patch implements:
WL#4264 "Backup: Stabilize Service Interface" -- all the
server prerequisites except si_objects.{h,cc} themselves (they can
be just copied over, when needed).
WL#4435: Support OUT-parameters in prepared statements.
(and all issues in the initial patches for these two
tasks, that were discovered in pushbuild and during testing).
Bug#39519: mysql_stmt_close() should flush all data
associated with the statement.
After execution of a prepared statement, send OUT parameters of the invoked
stored procedure, if any, to the client.
When using the binary protocol, send the parameters in an additional result
set over the wire. When using the text protocol, assign out parameters to
the user variables from the CALL(@var1, @var2, ...) specification.
The following refactoring has been made:
- Protocol::send_fields() was renamed to Protocol::send_result_set_metadata();
- A new Protocol::send_result_set_row() was introduced to incapsulate
common functionality for sending row data.
- Signature of Protocol::prepare_for_send() was changed: this operation
does not need a list of items, the number of items is fully sufficient.
The following backward incompatible changes have been made:
- CLIENT_MULTI_RESULTS is now enabled by default in the client;
- CLIENT_PS_MULTI_RESUTLS is now enabled by default in the client.
include/mysql.h:
Add a new flag to MYSQL_METHODS::flush_use_result
function pointer. This flag determines if all results
should be flushed or only the first one:
- if flush_all_results is TRUE, then cli_flush_use_result()
will read/flush all pending results. I.e. it will read
all packets while server status attribute indicates that
there are more results. This is a new semantic, required
to fix the bug.
- if flush_all_results is FALSE, the old sematic
is preserved -- i.e. cli_flush_use_result() reads data
until first EOF-packet.
include/mysql.h.pp:
Update the ABI with new calls (compatible changes).
include/mysql_com.h:
Add CLIENT_PS_OUT_PARAMS -- a client capability indicating that the client supportsю
libmysql/libmysql.c:
Add mysql_stmt_next_result() -- analogue of mysql_next_result() for binary protocol.
Fix a minor bug in alloc_fields() -- not all members were copied over,
and some only shallow-copied (catalog).
Flush all results in mysql_stmt_close() (Bug#39519).
libmysqld/lib_sql.cc:
Rename send_fields() -> send_result_set_metadata().
Refactoring: change prepare_for_send() so that it accepts only
what it really needs -- a number of elements in the list.
mysql-test/r/ps.result:
Update results: WL#4435.
mysql-test/t/ps.test:
WL#4435: A test case for an SQL-part of the problem.
sql-common/client.c:
Bug#39519.
Implement new functionality in cli_flush_use_result():
if flush_all_delete is TRUE, then it should read/flush
all pending results.
sql/Makefile.am:
Add a new header sql_prepare.h to the list
of build headers.
sql/events.cc:
Rename: Protocol::send_fields() ->
Protocol::send_result_set_metadata().
sql/handler.cc:
Rename: Protocol::send_fields() ->
Protocol::send_result_set_metadata().
sql/mysql_priv.h:
Move sql_prepare.cc-specific declarations to a new
header - sql_prepare.h.
sql/procedure.h:
Rename: Protocol::send_fields() ->
Protocol::send_result_set_metadata().
sql/protocol.cc:
Move the logic responsible for sending of one result
set row to the Protocol class. Define a template
for end-of-statement action.
Refactoring: change prepare_for_send() so that it accepts
only what it really needs -- a number of elements in the list.
Rename send_fields() to send_result_set_metadata().
sql/protocol.h:
Update with new declarations (WL#4435).
Rename send_fields() -> send_result_set_metadata().
prepare_for_send() only needs the number of columns to send,
and doesn't use the item list - update signature to require
only what's needed.
Add a new protocol type -- Protocol_local.
sql/repl_failsafe.cc:
Rename: Protocol::send_fields() ->
Protocol::send_result_set_metadata().
sql/slave.cc:
Rename: Protocol::send_fields() ->
Protocol::send_result_set_metadata().
sql/sql_acl.cc:
Rename: Protocol::send_fields() ->
Protocol::send_result_set_metadata().
sql/sql_base.cc:
Include sql_prepare.h (for Reprepare_observer).
sql/sql_cache.cc:
Extend the query cache flags block to be able
to store a numeric id for the result format,
not just a flag binary/non-binary.
sql/sql_class.cc:
Update to use the rename of Protocol::send_fields()
to Protocol::send_result_set_metadata().
Use Protocol::send_one_result_set_row().
sql/sql_class.h:
Move the declaration of Reprepare_observer to the
new header - sql_prepare.h.
Update to the new signature of class Protocol::send_fields().
sql/sql_connect.cc:
Use a protocol template method instead of
raw NET layer API at the end of a statement.
sql/sql_cursor.cc:
Rename: Protocol::send_fields() ->
Protocol::send_result_set_metadata().
sql/sql_error.cc:
Rename: Protocol::send_fields() ->
Protocol::send_result_set_metadata().
sql/sql_handler.cc:
Rename: Protocol::send_fields() ->
Protocol::send_result_set_metadata().
Use new method Protocol::send_one_result_set_row().
sql/sql_help.cc:
Rename: Protocol::send_fields() ->
Protocol::send_result_set_metadata().
sql/sql_lex.cc:
Initialize multi_statements variable.
Add a handy constant for empty lex
string.
sql/sql_lex.h:
Add a separate member for a standalone
parsing option - multi-statements support.
sql/sql_list.cc:
sql_list.h is a standalone header now,
no need to include mysql_priv.h.
sql/sql_list.h:
Make sql_list.h a stand-alone header.
sql/sql_parse.cc:
Include sql_prepare.h for prepared
statements- related declarations.
Use a new Protocol template method to end
each statement (send OK, EOF or ERROR to
the client).
sql/sql_prepare.cc:
Implement Execute Direct API (WL#4264),
currently unused. It will be used by the service
interface (Backup).
Use a new header - sql_prepare.h.
Add support for OUT parameters in the
binary and text protocol (prepared statements
only).
sql/sql_prepare.h:
Add a new header to contain (for now)
all prepared statement- external
related declarations.
sql/sql_profile.cc:
Rename: Protocol::send_fields() ->
Protocol::send_result_set_metadata().
sql/sql_repl.cc:
Rename: Protocol::send_fields() ->
Protocol::send_result_set_metadata().
sql/sql_select.cc:
Rename: Protocol::send_fields() ->
Protocol::send_result_set_metadata().
sql/sql_show.cc:
Rename: Protocol::send_fields() ->
Protocol::send_result_set_metadata().
sql/sql_string.h:
Add a way to convert a String to LEX_STRING.
sql/sql_table.cc:
Rename: Protocol::send_fields() ->
Protocol::send_result_set_metadata().
sql/sql_update.cc:
Remove an extraneous my_error(). The error
is already reported in update_non_unique_table_error().
sql/sql_yacc.yy:
Support for multi-statements is an independent
property of parsing, not derived from
the protocol type.
tests/mysql_client_test.c:
Add tests for WL#4435 (binary protocol).

message:
Cover four special cases of WL#4166 with tests:
- when the query cache is disabled at the time of prepared statement
reprepare
- when long data parameters are used
- when character_set_connection != character_set_client, and a parameter
conversion takes place
- when parameter data is out of acceptable range, e.g. year 10000 is
supplied as part of MYSQL_TYPE_DATETIME value. The server is supposed
to warn in such case.

CMakeLists.txt files cleanup
- remove SAFEMALLOC and SAFE_MUTEX definitions that were
present in *each* CMakeLists.txt. Instead, put them into top level
CMakeLists.txt, but disable on Windows, because
a) SAFEMALLOC does not add any functionality that is not already
present in Debug C runtime ( and 2 safe malloc one on top of the other
only unnecessarily slows down the server)
b)SAFE_MUTEX does not work on Windows and have been
explicitely disabled on Windows with #undef previously. Fortunately,
ntdll does pretty good job identifying l problems with
CRITICAL_SECTIONs.
DebugBreak()s on using uninited critical section, unlocking unowned
critical section)
-Also, remove occationally used -D_DEBUG (added by compiler
anyway)
sql/udf_example.c:
use unixish end of line

Vladislav Vaintroub 2008-11-03
Cleanup CMakeLists.txt(s) - remove winsock2 (ws2_32) from
TARGET_LINK_LIBRARIES.
Every exe or dll linked with mysys needs ws2_32, because
mysys uses winsock function WSAStartup in my_init().
However, there is no need to explicitely add ws2_32 to
the list of TARGET_LINK_LIBRARIES multiple times.
Visual Studio comes with a handy pragma that tells linker
to add library. So patch replaces bunch of ws2_32 in
CMakeLists with single pragma comment(lib,"ws2_32")
in my_init.c
Additionally, reference to non-existing "debug" library
has been removed from TARGET_LINK_LIBRARIES. The correct
name of the library is "dbug".

Always use TLS functions instead of __declspec(thread) to access
thread local storage variables.
The change removes the necessity to recomplile the same source
files twice - with USE_TLS for DLLs and without USE_TLS for EXEs.
Real benefit of this change is better readability and maintainability
of TLS functions within MySQL.
There is a performance loss using TlsXXX functions compared to __declspec
but the difference is negligible in practice. In a sysbench-like benchmark
I ran with with TlsGetValue, pthread_[get|set]_specific was called 600000000
times and took 0.17sec of total 35min CPU time, or 0.008%.
client/mysql.cc:
Remove leading whitespace.
Remove extra text after #else directive.
client/mysqldump.c:
Function does not take a parameter.
mysys/array.c:
buffer is a uchar pointer.
sql/item.cc:
Assert if it should not happen.
storage/myisam/mi_check.c:
Cast to expected type. This is probably a bug, but it is
casted in a similar way in another part of the code.
storage/ndb/include/mgmapi/ndb_logevent.h:
Apply fix from cluster team.
tests/mysql_client_test.c:
Remove extraneous slash.
The problem is that the lexer could inadvertently skip over the
end of a query being parsed if it encountered a malformed multibyte
character. A specially crated query string could cause the lexer
to jump up to six bytes past the end of the query buffer. Another
problem was that the laxer could use unfiltered user input as
a signed array index for the parser maps (having upper and lower
bounds 0 and 256 respectively).
The solution is to ensure that the lexer only skips over well-formed
multibyte characters and that the index value of the parser maps
is always a unsigned value.
mysql-test/r/ctype_recoding.result:
Update test case result: ending backtick is not skipped over anymore.
sql/sql_lex.cc:
Characters being analyzed must be unsigned as they can be
used as indexes for the parser maps. Only skip over if the
string is a valid multi-byte sequence.
tests/mysql_client_test.c:
Add test case for Bug#45010
Post-merge fix: test case could fail due to a conversion of the
max_join_size value to a integer. Fixed by preserving the value
as a string for comparison purposes.
tests/mysql_client_test.c:
Preserve max_join_size value as a string instead of converting
it to a integer -- value can be larger then the type used.
unnecessarily
The problem is that libmysqlclient.so is built with THREAD
undefined, while a client compiling against the same header
files will see THREAD as defined and definitions in
my_pthread.h will be included, possibly resulting in undefined
symbols that cannot be resolved with libmysqlclient.so.
The suggested solution is to require that clients wanting to
link with libmysqlclient.so should be built with
MYSQL_CLIENT_NO_THREADS defined. This requires a documentation
change, and more details for this will be supplied if this
patch is approved.
The MYSQL_CLIENT_NO_THREADS define was renamed from
UNDEF_THREADS_HACK, to get a more suitable (less suspicious)
name for the define. (The UNDEF_THREADS_HACK is retained for
backwards compatibility, though.)
This patch is also in anticipation of WL#4958, which will
remove this problem altogether by dropping the building of
libmysqlclient.

sql/sql_table.cc:
We should skip error sending then we should return
warnings to client as some functions may send its
own errors, so we should set no_warnings_for_error= 0
only in case of warning.
The fix is to enable message storing into error message
list for 'drop table' command(only for error case).
tests/mysql_client_test.c:

without proper formatting
The problem is that a suitably crafted database identifier
supplied to COM_CREATE_DB or COM_DROP_DB can cause a SIGSEGV,
and thereby a denial of service. The database name is printed
to the log without using a format string, so potential
attackers can control the behavior of my_b_vprintf() by
supplying their own format string. A CREATE or DROP privilege
would be required.
This patch supplies a format string to the printing of the
database name. A test case is added to mysql_client_test.
sql/sql_parse.cc:
Added format strings.
tests/mysql_client_test.c:
Added new test case.
per-file comments:
tests/mysql_client_test.c
the test for bug 37956 isn't relevant anymore.
The query there 'select point(?,?)' doesn't produce an error.
This is a back port from 5.1 to 5.0.
Fix for BUG 20023: mysql_change_user() resets the value
of SQL_BIG_SELECTS.
The bug was that SQL_BIG_SELECTS was not properly set
in COM_CHANGE_USER.
The fix is to update SQL_BIG_SELECTS properly.
sql/sql_class.cc:
Update THD::options with the respect to SQL_BIG_SELECTS
in COM_CHANGE_USER.
tests/mysql_client_test.c:
Add a test case BUG#20023.
*with --with-charset=utf8*
Problem: wrong LONG TEXT field length is sent to a client
when multibyte server character set used.
Fix: always limit field length sent to a client to 2^32,
as we store it in 4 byte slot.
Note: mysql_client_test changed accordingly.
sql/protocol.cc:
Fix for bug#19829:make test Failed in mysql_client_test
*with --with-charset=utf8*
- limit field length sent to client to UINT_MAX32 as
it may exceeds 32 bit slot for LONG TEXT fields if
thd_charset->mbmaxlen > 1.
tests/mysql_client_test.c:
Fix for bug#19829:make test Failed in mysql_client_test
*with --with-charset=utf8*
- checking field members have in mind that field length
is limited to UINT_MAX32.
returns short string value.
Multibyte character sets were not taken into account when
calculating max_length in Item_param::convert_str_value(). As a
result, string parameters of a prepared statement could be
truncated later when calculating string length in characters by
dividing length in bytes by the charset's mbmaxlen value (e.g. in
Field_varstring::store()).
Fixed by taking charset's mbmaxlen into account when calculating
max_length in Item_param::convert_str_value().
sql/item.cc:
Multiply string's length in characters by charset's mbmaxlen when
calculating max_length.
tests/mysql_client_test.c:
Added a test case for bug #41078.
- Remove bothersome warning messages. This change focuses on the warnings
that are covered by the ignore file: support-files/compiler_warnings.supp.

The problem is that the query cache stores packets containing
the server status of the time when the cached statement was run.
This might lead to a wrong transaction status in the client side
if a statement is cached during a transaction and is later served
outside a transaction context (and vice-versa).
The solution is to take into account the transaction status when
storing in and serving from the query cache.

The code to get read the value of a system variable was extracting its value
on PREPARE stage and was substituting the value (as a constant) into the parse tree.
Note that this must be a reversible transformation, i.e. it must be reversed before
each re-execution.
Unfortunately this cannot be reliably done using the current code, because there are
other non-reversible source tree transformations that can interfere with this
reversible transformation.
Fixed by not resolving the value at PREPARE, but at EXECUTE (as the rest of the
functions operate). Added a cache of the value (so that it's constant throughout
the execution of the query). Note that the cache also caches NULL values.
Updated an obsolete related test suite (variables-big) and the code to test the
result type of system variables (as per bug 74).

Send_field.org_col_name has broken value on secondary execution.

tests/mysql_client_test.c:
test case fix
The test was changed because now forgotten attributes are properly set.
Length value is the length of the field,
Max_length is the length of the field value.
So Max_length can not be more than Length.
The fix: fixed calculation of the Item_empty_string item length
(Patch applied and queued on demand of Trudy/Davi.)

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

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.

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

The problem was that the COM_STMT_SEND_LONG_DATA was sending a response
packet if the prepared statement wasn't found in the server (due to
reconnection). The commands COM_STMT_SEND_LONG_DATA and COM_STMT_CLOSE
should not send any packets, even error packets should not be sent since
they are not expected by the client API.
The solution is to clear generated during the execution of the aforementioned
commands and to skip resend of prepared statement commands. Another fix is
that if the connection breaks during the send of prepared statement command,
the command is not sent again since the prepared statement is no longer in the
server.
libmysql/libmysql.c:
The mysql handle might be reset after a reconnection.
Pass the now used stmt argument to cli_advanced_command.
sql-common/client.c:
Don't resend command if the connection broke and it's a prepared
statement command. If the session is broken, prepared statements
on the server are gone, set the error accordanly.
sql/sql_prepare.cc:

command.

Under some circumstances, the mysql_insert_id() value after SELECT ...
INSERT could return a wrong value. This could happen when the last
SELECT ... INSERT did not involve an AUTO_INCREMENT column, but the
value of mysql_insert_id() was changed by some previous statements.
Fixed by checking the value of thd->insert_id_used in
select_insert::send_eof() and returning 0 for mysql_insert_id() if it
is not set.
sql/sql_insert.cc:
Do not return thd->last_insert_id unconditionally in

--local-infile=0 checks can be bypassed by sending a FETCH LOCAL FILE response
Add a check for CLIENT_LOCAL_FILES before sending a local file.
Beware, that all binary distributions enable sending of local files and it's up
to the programs which use libmysql to disable it, if they don't use this functionality.
Otherwise they are not safe.
client/mysqltest.c:
Enable LOAD DATA LOCAL INFILE for the test suite, like some rpl and ndb test.
sql-common/client.c:
Check if the client has LOAD DATA LOCAL INFILE disabled and
don't serve such requests from the server. This is not 100% proof,
as if the client has this enabled, in all binary builds for BC,
the check won't work and the client can be tricked into sending a
local file.

Executing a prepared statement associated with a materialized
cursor yields to the client a metadata packet with wrong table
and database names. The problem was occurring because the server
was sending the the name of the temporary table used by the cursor
instead of the table name of the original table. The same problem
occurs when selecting from views, in which case the table name was
being sent and not the name of the view.
The solution is to fill the list item from the temporary table but
preserving the table and database names of the original fields. This
is achieved by tweaking the Select_materialize to accept a pointer to
the Materialized_cursor class which contains the item list to be filled.
sql/sql_cursor.cc:
Fill the item list in the send_fields method and preserve
the table and database name of the fields.

insert ... select.
The 5.0 manual page for mysql_insert_id() does not mention anything
about INSERT ... SELECT, though its current behavior is incosistent
with what the manual says about the plain INSERT.
Fixed by changing the AUTO_INCREMENT and mysql_insert_id() handling
logic in INSERT ... SELECT to be consistent with the INSERT behavior,
the manual, and the changes in 5.1 introduced by WL3146:
- mysql_insert_id() now returns the first automatically generated
AUTO_INCREMENT value that was successfully inserted by INSERT ... SELECT
- if an INSERT ... SELECT statement is executed, and no automatically
generated value is successfully inserted, mysql_insert_id() now returns
the ID of the last inserted row.
sql/sql_class.h:
Replaced last_insert_id with autoinc_value_of_last_inserted_row to be
consistent with 5.1 code.
sql/sql_insert.cc:
Revised the AUTO_INCREMENT and mysql_insert_id() handling logic in
INSERT ... SELECT to be consistent with INSERT behavior, the manual, and
changes in 5.1 introduced by WL3146:
- mysql_insert_id() now returns the first automatically generated
AUTO_INCREMENT value that was successfully inserted;
- if an INSERT ... SELECT statement is executed, and no automatically
generated value is successfully inserted, mysql_insert_id() now returns
the ID of the last inserted row.
tests/mysql_client_test.c:
Backported the test cases related to INSERT ... SELECT and
mysql_insert_id() from WL3146 patch to 5.0.

Referencing an element from the SELECT list in a WHERE
clause is not permitted. The namespace of the WHERE
clause is the table columns only. This was not enforced
correctly when resolving outer references in sub-queries.
Fixed by not allowing references to aliases in a
sub-query in WHERE.

crashes.
MySQL distributions contain a number of programs that are used only by
the MySQL test suite internally, i.e. they are not indended to be
invoked directly by a user. As a result, such programs are not
documented, do not have any built-in help or proper error reporting,
which may confuse users.
This patch fixes the problem with the following changes:
- mytest, libmysqltest and all references to them were removed from the
distribution since they are not used anymore
- bug25714 now displays an error message when run with incorrect
arguments or with the --help option
- mysql_client_test now does not call abort() in case of errors,
instead it does a clean exit() with a proper error status.

command and reported to a client.
The fact that a timestamp field will be set to NO on UPDATE wasn't shown
by the SHOW COMMAND and reported to a client through connectors. This led to
problems in the ODBC connector and might lead to a user confusion.
A new filed flag called ON_UPDATE_NOW_FLAG is added.
Constructors of the Field_timestamp set it when a field should be set to NOW
on UPDATE.
The get_schema_column_record function now reports whether a timestamp field
will be set to NOW on UPDATE.
