This is the non-ndb part of the patch.
The return value of mysql_bin_log.write was ignored by most callers,
which may lead to inconsistent on master and slave if the transaction
was committed while the binlog was not correctly written. If
my_error() is call in mysql_bin_log.write, this could also lead to
assertion issue if my_ok() or my_error() is called after.
This fixed the problem by let the caller to check and handle the
return value of mysql_bin_log.write. This patch only adresses the
simple cases.

Bug#28870 check that table locks are released/reset
The problem is that some mysql_lock_tables error paths are not
resetting the tables lock type back to TL_UNLOCK. If the lock
types are not reset properly, a table might be returned to the
table cache with wrong lock_type.
The proposed fix is to ensure that the tables lock type is always
properly reset when mysql_lock_tables fails. This is a
incompatible change with respect to the process state information.
sql/lock.cc:
Merge mysql_lock_tables cleanup sequence and the reset_lock_data
function into a single function and take steps to ensure it is
always called for each error exit path. Also remove references
to the redundant THD::locked variable which was almost exclusively
used by this function and the same information is already on proc_info.
sql/sql_class.cc:
Remove references to the THD::locked variable.
sql/sql_class.h:
Remove the THD::locked variable.
sql/sql_show.cc:
Remove references to THD:locked, state_info will now default to proc_info.
- Moved some code from innodb_plugin to xtradb, to ensure that all tests runs
- Did changes in pbxt and maria storage engines becasue of changes in thd->query
- Reverted wrong code in sql_table.cc for how ROW_FORMAT is used.
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.

Bug#15192 "fatal errors" are caught by handlers in stored procedures
The problem is that fatal errors (e.g.: out of memory) were being
caught by stored procedure exception handlers which could cause
the execution to not be stopped due to a continue handler.
The solution is to not call any exception handler if the error is
fatal and send the fatal error to the client.

Bug#41860: Without Windows named pipe
The problem was that the patch for Bug#10374 broke named pipe
and shared memory transports on Windows due to a failure to
implement a dummy poll method for transports other than BSD
sockets. Another problem was that mysqltest lacked support
for named pipe and shared memory connections, which lead to
misleading test cases that were supposed run common queries
over both transports.
The solution is to properly implement, at the VIO layer, the
poll and is_connected methods. The is_connected method is
implemented for every suppported transport and the poll one
only where it makes sense. Furthermore, support for named pipe
and shared memory connections is added to mysqltest as to
enable testing of both transports using the test suite.
client/mysqltest.cc:
Add support for named pipe and shared memory connections.
include/violite.h:
Move private functions to vio/vio_priv.h
Add poll_read and is_connected methods.

Add poll_read and is_connected methods.
vio/vio_priv.h:
Add private functions.

Bug#10374 GET_LOCK does not let connection to close on the server side if it's aborted
The problem is that the server doesn't detect aborted connections which
are waiting on a lock or sleeping (user sleep), wasting system resources
for a connection that is already dead.
The solution is to peek at the connection every five seconds to verify if
the connection is not aborted. A aborted connection is detect by polling
the connection socket for available data to be read or end of file and in
case of eof, the wait is aborted and the connection killed.

Bug no 32858 was fixed in two different ways in what was
then called mysql 5.1 and 6.0. The fix in 6.0 was very
different since bugfix no 33204 was present. Furthermore,
the two fixes were not compatible. Hence in order to
backport Bug#33204 to the 5.1-based mysql-next-mr-bugfixing,
it was necessary to remove the 5.1 fix of 32858 and apply
the 6.0 version of the fix.

Non-transactional updates that take place inside a transaction present problems
for logging because they are visible to other clients before the transaction
is committed, and they are not rolled back even if the transaction is rolled
back. It is not always possible to log correctly in statement format when both
transactional and non-transactional tables are used in the same transaction.
In the current patch, we ensure that such scenario is completely safe under the
ROW and MIXED modes.

mysql-5.1-rpl-merge has been made a mirror of mysql-next-mr:
- "mysql-5.1-rpl-merge$ bzr pull ../mysql-next-mr"
This is the first cset (merge/...) committed after pulling
from mysql-next-mr.
2630.39.1, 2630.28.29, 2630.34.3, 2630.34.2, 2630.34.1, 2630.29.29,
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

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().

Update results: WL#4435.
mysql-test/t/ps.test:
WL#4435: A test case for an SQL-part of the problem.

of build headers.
sql/events.cc:
Rename: Protocol::send_fields() ->

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,

only what's needed.
Add a new protocol type -- Protocol_local.
sql/repl_failsafe.cc:
Rename: Protocol::send_fields() ->
Protocol::send_result_set_metadata().

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.

all prepared statement- external
related declarations.

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.

If a thread is killed in the server, we throw "shutdown" only if one is actually in
progress; otherwise, we throw "query interrupted".
Control-C in the mysql command-line client is "incremental" now.
First Control-C sends KILL QUERY (when connected to 5.0+ server, otherwise, see next)
Next Control-C sends KILL CONNECTION
Next Control-C aborts client.
As the first two steps only pertain to an existing query,
Control-C will abort the client right away if no query is running.
client will give more detailed/consistent feedback on Control-C now.
client/mysql.cc:
Extends Control-C handling; enhances up feedback to user.
On 5.0+ servers, we try to be nice and send KILL QUERY first
if Control-C is pressed in the command-line client, but if
that doesn't work, we now give the user the opportunity to
send KILL CONNECTION with another Control-C (and to kill the
client with another Control-C if that somehow doesn't work
either).
mysql-test/t/flush_read_lock_kill.test:
we're getting correct "thread killed" rather than
"in shutdown" error now
mysql-test/t/kill.test:
we're getting correct "thread killed" rather than
"in shutdown" error now
mysql-test/t/rpl000001.test:
we're getting correct "thread killed" rather than
"in shutdown" error now
mysql-test/t/rpl_error_ignored_table.test:
we're getting correct "thread killed" rather than
"in shutdown" error now
sql/records.cc:
make error messages on KILL uniform for rr_*()
by folding that handling into rr_handle_error()
sql/sql_class.h:
Only throw "shutdown" when we have one flagged as being in progress;
otherwise, throw "query interrupted" as it's likely to be "KILL CONNECTION"
or related.
sql/sql_cache.cc:
Use my_hash_init() on Windows as well.
sql/sql_class.h:
Use struct Query_cache_block (not class) for forward declaration,
realing the code to match 6.0 alignment.
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.
Post-push fix.
Problem: After the original bugfix, if a statement is unsafe,
binlog_format=mixed, and engine is statement-only, a warning was
generated and the statement executed. However, it is a fundamental
principle of binlogging that binlog_format=mixed should guarantee
correct logging, no compromise. So correct behavior is to generate
an error and don't execute the statement.
Fix: Generate error instead of warning.
Since issue_unsafe_warnings can only generate one error message,
this allows us to simplify the code a bit too:
decide_logging_format does not have to save the error code for
issue_unsafe_warnings

mysql-test/suite/rpl_ndb/t/rpl_ndb_binlog_format_errors.test:
updated test:
- ER_BINLOG_UNSAFE_AND_STMT_ENGINE is now an error.
- added test for multiple types of unsafety
sql/share/errmsg.txt:
- Reformulated ER_BINLOG_UNSAFE_AND_STMT_ENGINE to reflect that it
is now an error, not a warning.
- Added "Reason for unsafeness" to ER_BINLOG_UNSAFE_STATEMENT and
ER_BINLOG_UNSAFE_AND_STMT_ENGINE.
sql/sql_class.cc:
In decide_logging_format:
- generate an error immediately in case 3, instead of scheduling a
warning to be generated later. also updated comments accordingly
- in case 7, there is only one unsafe warning error code now, so we
don't need to store it in binlog_unsafe_warning_flags
(see changes in sql_lex.h)
- fixed compilation warning in DBUG_PRINT
In issue_binlog_warning:
- moved array of error codes to sql_lex.h (so that they are
accessible also from decide_logging_format)
- simplified code after the first set of bits in
binlog_unsafe_warning_flags was removed
sql/sql_class.h:
- got rid of enum_binlog_stmt_warning. It's not needed anymore
since we only have one type of unsafe warning (one of them
turned into an error)
- updated comments accordingly
sql/sql_lex.cc:
added initialization of the array of error codes that has been
moved from THD::issue_unsafe_warnings to LEX.
sql/sql_lex.h:
Moved array of error codes from THD::issue_unsafe_warnings to LEX.
