defined to succeed:

include/trx0sys.h: Allow Hot Backup build to see some
                   TRX_SYS_DOUBLEWRITE_... macros. 
trx/trx0sys.c:     Exclude trx_sys_close() function from Hot Backup build.

branches/zip: dict_table_check_for_dup_indexes(): Assert that the
data dictionary mutex is being held while table->indexes is accessed.
This is already the case.

Currently, only dict_table_get_next_index() and dict_table_get_first_index()
are being invoked without holding dict_sys->mutex.

branches/zip: ChangeLog: Document r4922 that was forgotten.

Problem: EXPLAIN EXTENDED was trying to resolve references to 
freed temporary table fields for GROUP_CONCAT()'s ORDER BY arguments.

Fix: use stored original GROUP_CONCAT()'s arguments in such a case.

 function on windows
               
When making sure that the directory path ends up with a 
slash/backslash we need to check for the correct length of 
the buffer and trim at the appropriate location so we don't
write past the end of the buffer.

The crash is the result of an attempt made by JOIN::optimize to evaluate
the WHERE condition when no records have been actually read.
The fix is to remove erroneous 'outer_join' variable check.

The crash happens because greedy_serach
can not determine best plan due to
wrong inner table dependences. These
dependences affects join table sorting
which performs before greedy_search starting.
In our case table which has real 'no dependences'
should be put on top of the list but it does not
happen as inner tables have no dependences as well.
The fix is to exclude RAND_TABLE_BIT mask from
condition which checks if table dependences
should be updated.

  function on windows

When making sure that the directory path ends up with a 
slash/backslash we need to check for the correct length of 
the buffer and trim at the appropriate location so we don't
write past the end of the buffer.

CHECK_FIELD_IGNORE was treated as CHECK_FIELD_ERROR_FOR_NULL;
UPDATE...SET...NULL on NOT NULL fields behaved differently after
a trigger.

Now distinguishes between IGNORE and ERROR_FOR_NULL and save/restores
check-field options.

When mysqlbinlog was given the --database=X flag, it always printed
'ROLLBACK TO', but the corresponding 'SAVEPOINT' statement was not
printed. The replicated filter(replicated-do/ignore-db) and binlog
filter (binlog-do/ignore-db) has the same problem. They are solved
in this patch together.

After this patch, We always check whether the query is 'SAVEPOINT'
statement or not. Because this is a literal check, 'SAVEPOINT' and
'ROLLBACK TO' statements are also binlogged in uppercase with no
any comments.

The binlog before this patch can be handled correctly except one case
that any comments are in front of the keywords. for example:
 /* bla bla */ SAVEPOINT a;
 /* bla bla */ ROLLBACK TO a;

The log event of 'CREATE EVENT' was being binlogged with garbage
at the end of the query if 'CREATE EVENT' is followed by another SQL statement
and they were executed as one command.
for example:
    DELIMITER |;
    CREATE EVENT e1 ON EVERY DAY DO SELECT 1; SELECT 'a';
    DELIMITER ;|
When binlogging 'CREATE EVENT', we always create a new statement with definer
and write it into the log event. The new statement is made from cpp_buf(preprocessed buffer).
which is not a c string(end with '\0'), but it is copied as a c string.

In this patch, cpp_buf is copied with its length.

Fix a non-determinism in innodb_bug38231.

Reported by:	Sergey Vojtovich <svoj@Sun.COM>

The crash happens because of incorrect max_length calculation
in QUOTE function(due to overflow). max_length is set
to 0 and it leads to assert failure.
The fix is to cast expression result to
ulonglong variable and adjust it if the
result exceeds MAX_BLOB_WIDTH.

There was no way to repair corrupt ARCHIVE data file,
when unrecoverable data loss is inevitable.

With this fix REPAIR ... EXTENDED attempts to restore
as much rows as possible, ignoring unrecoverable data.

Normal REPAIR is still able to repair meta-data file
only.

by sort and fulltext keys.

Min value for myisam_sort_buffer_size is 4096.

Repairing MyISAM table with fulltext indexes and low
myisam_sort_buffer_size may crash the server.

Estimation of number of index entries was done incorrectly,
causing further assertion failure or server crash.

Docs note: min value for myisam_sort_buffer_size has been
changed from 4 to 4096.

Invalid memory read if HANDLER ... READ NEXT is executed
after failed (e.g. empty table) HANDLER ... READ FIRST.

The problem was that we attempted to perform READ NEXT,
whereas there is no pivot available from failed READ FIRST.

With this fix READ NEXT after failed READ FIRST equals
to READ FIRST.

This bug affects MyISAM tables only.

When MyISAM writes newly created index page it may be
initialized partially. In other words some bytes of
sensible data and uninitialized tail of the page may
go into index file.

Under certain rare circumstances these hunks of memory
may contain data that would be otherwise inaccessible
to user, like passwords or data from other tables.

Fixed by initializing memory for temporary MyISAM key
buffer to '\0'.

No test case for this fix as it is heavily covered by
existing tests.

with a more robust condition which waits for the TRUNCATE and LOCK commands
to appear in information_schema.processlist. This could also break if there
