32bit builds with the --enable-assembler flag (enabled by default)
fail with an error message: undefined reference to `strmov_overlapp'.

Since the fix for bug 48866 we use a home-grown strmov function
instead of the ctpcpy function, but the source file for this
function was missed in the Makefile.am.

The strings/Makefile.am file has been modified to include strmov.c
file into ASSEMBLER_x86 and ASSEMBLER_sparc32 sections.

Recover the right contents of the index file at the end of the test case.

Manually deleteing one or more entries from 'master-bin.index', will
cause master infinitely loop to send one binlog file. 

When starting a dump session, master opens index file and search the binlog file
which is being requested by the slave. The position of the binlog file in the
index file is recorded. it will be used to find the next binlog file when current
binlog file has dumped completely. As only the position is used, it may
not get the correct file if some entries has been removed manually from the index file.
the master will reopen the current binlog file which has been dump completely
and redump it if it can not get the next binlog file's name from index file.
It obviously is a logical error.


Even though it is allowed to manually change index file,
but it is not recommended. so after this patch, master
sends a fatal error to slave and close the dump session if a new binlog file
has been generated and master can not get it from the index file.

This bug is the same problem as Bug 49836 for 5.1 versions.

      
In statement-based or mixed-mode replication, use DROP TEMPORARY TABLE
to drop multiple tables causes different errors on master and slave, 
when one or more of these tables do not exist. Because when executed
on slave, it would automatically add IF EXISTS to the query to ignore
all ER_BAD_TABLE_ERROR errors.

To fix the problem, do not add IF EXISTS when executing DROP TEMPORARY
TABLE on the slave, and clear the ER_BAD_TABLE_ERROR error after
execution if the query does not expect any errors.

           to make the test run gracefully on windows.

There was also a syntax error in windows part of the test.

Several problems fixed : 
1. Non constant expressions in UNION ... ORDER BY were not correctly cleaned up
in st_select_lex_unit::cleanup() causing crashes in EXPLAIN EXTENDED because of
fields quoted by these expressions pointing to the already freed temporary table
used to calculate the UNION.
Fixed by correctly cleaning up expressions of any depth.

2. Subqueries in the order by part of UNION ... ORDER BY ... caused a crash in 
EXPLAIN EXTENDED because of a transformation attempt made during EXPLAIN EXTENDED
execution. Fixed by not doing the transformation when in EXPLAIN.

3. Fulltext functions caused crash when in the ORDER BY part of an un-parenthesized
UNION that gets "promoted" to be valid for the whole union, e.g. 
SELECT * FROM t1 UNION SELECT * FROM t2 ORDER BY MATCHES (a) AGAINST ('abc' IN BOOLEAN MODE).
This is a case that demonstrates a more general problem of parts of the query being
moved to another level. When doing such transformation late in the optimization run
when most of the flags about the contents of the query are already aggregated it's possible 
to "split" the flags so that they correctly reflect the new queries after the transformation.
In specific the ST_SELECT_LEX::ftfunc_list is holding all the free text function for all the 
parts of the second SELECT in the UNION and we don't know what part of that is in the ORDER BY
that we're to move to the UNION level and what part is about the other parts of the second SELECT.
Fixed by throwing and error when such statements are about to be processed by adding a check 
for the presence of MATCH() inside the ORDER BY clause that's going to get promoted to UNION.
To workaround this new limitation one must parenthesize the UNION SELECTs and provide a real 
global ORDER BY for the UNION outside of the parenthesis.

on re-execution of prepared statement

Problem: some (see eq_ref_table()) ORDER BY/GROUP BY optimization
is called before each PS execution. However, we don't properly 
initialize its stucture every time before the call.

Fix: properly initialize the sturture used.

  freezes (win) the server

The check for equality was assuming the field object is always 
created. If it's not it was de-referencing a NULL pointer.
Fixed to use the data in the create object instead.

the declaration of THR_LOCK_myisam_mmap in mi_static 
is redundant as it accessible via the extern declaration 
in include/myisam.h

If first call of the procedure is failed on
the open_table stage stmt_arena->state is set to
EXECUTED state. On second call(if no errors on
open_table stage) it leads to use of worng memory arena
in find_field_in_view() function as
thd->stmt_arena->is_stmt_prepare_or_first_sp_execute()
returns FALSE for EXECUTED state. The item is created 
not in its own arena and it leads to crash on further
calls of the procedure.
The fix: 
change state of arena only if
no errors on open_table stage happens.

At the end of execution top level join execution
we cleanup this join with true argument.
It leads to underlying join cleanup(subquery) with true argument too
and to tmp_table_param->field array cleanup which is required later.
The problem is that Item_func_set_user_var does not set
result_filed which leads to unnecessary repeated excution of subquery
on final stage.
The fix is to set result_field for Item_func_set_user_var.

branches/5.1: Merge r4922 from branches/zip.

This the fix for the first part of Bug #41609 from InnoDB Plugin to
the built-in InnoDB in MySQL 5.1. This allows InnoDB Hot Backup to
back up a database while the built-in InnoDB in MySQL 5.1 is creating
temporary tables. (This fix does not address the printouts about
missing .ibd files for temporary tables at InnoDB startup, which was
committed to branches/zip in r6252.)

rb://219 approved by Sunny Bains.

branches/zip: Distinguish temporary tables in MLOG_FILE_CREATE.
This addresses Mantis Issue #23 in InnoDB Hot Backup and some
of MySQL Bug #41609.

In MLOG_FILE_CREATE, we need to distinguish temporary tables, so that
InnoDB Hot Backup can work correctly.  It turns out that we can do this
easily, by using a bit of the previously unused parameter for page number.
(The page number parameter of MLOG_FILE_CREATE has been written as 0 
ever since MySQL 4.1, which introduced MLOG_FILE_CREATE.)

MLOG_FILE_FLAG_TEMP: A flag for indicating a temporary table in
the page number parameter of MLOG_FILE_ operations.

fil_op_write_log(): Add the parameter log_flags.

fil_op_log_parse_or_replay(): Add the parameter log_flags.
Do not replay MLOG_FILE_CREATE when MLOG_FILE_FLAG_TEMP is set in log_flags.
This only affects ibbackup --apply-log.  InnoDB itself never replays file
operations.

branches/5.1: fix bug#49267: innodb-autoinc.test fails on windows
because of different case mode

There is no change to the InnoDB code, only to fix test case by
changing "T1" to "t1".

When the $diff_statement variable for diff_master_slave.inc was
put in multiple lines, the rear part of the statement would be 
missing when being executed on Windows systems.

Fixed the problem by always putting the value for $diff_statement
in one line.

unnecessarily

Changing an instance of the define that was missed
in the original commit due to the fact that it was
misspelled.

Post-merge fix: wait for statement result before disconnecting.
Otherwise, the statement might affect unrelated tests.
