Archive engine returns wrong values for average record length
and max data length.
With this fix they're calculated as following:
- max data length is 2 ^ 63 where large files are supported
and INT_MAX32 where this is not supported;
- average record length is data length / records in data file.

The parser rule for expressions in a udf parameter list contains
two hacks:
First, the parser input stream is read verbatim, bypassing
the lexer.
Second, the Item::name field is overwritten. If the argument to a
udf was a field, the field's name as seen by name resolution was
overwritten this way.
If the field name was quoted or escaped, it would appear as e.g. "`field`".
Fixed by not overwriting field names.

This test case uses mysqlbinlog to dump the content of master-bin.000001,
but the content of master-bin.000001 is not that this test needs.
MTR runs a lot of test cases on one server, so when this test starts, the current binlog file
might not be master-bin.000001, or there are other events are written by tests before.
'RESET MASTER' command must be called at the begin, it ensures that binlog of this test
is wrote to master-bin.000001 correctly.
Three other tests have the same problem, They were fixed together.

Postfix.
extra/rpl_tests/rpl_row_sp006.test had changed to fix this bug.
extra/rpl_tests/rpl_row_sp006.test is also referenced by rpl_ndb_sp006,
So rpl_row_sp006.result must be changed too.
The plugin feature is disabled, you need HAVE_DLOPEN
Selectively skip tests that require dynamic loading (ie: static builds).

on subquery inside a SP
Problem: repeated call of a SP containing an incorrect query with a
subselect may lead to failed ASSERT().
Fix: set proper sublelect's state in case of error occured during
subquery transformation.

Fix for bug#46629: Item_in_subselect::val_int(): Assertion `0'
on subquery inside a SP
- don't set Item_subselect::changed in the Item_subselect::fix_fields()
if an error occured during subquery transformation.
That prevents us of further processing incorrect subqueries after
Item_in_subselect::select_in_like_transformer().

name as existing view
When trying to create a table with the same name as existing view with
join, mysql server crashes.
The problem is when create table is issued with the same name as view, while
verifying with the existing tables, we assume that base table object is
created always.
In this case, since it is a view over multiple tables, we don't have the
mysql derived table object.
Fixed the logic which checks if there is an existing table to not to assume
that table object is created when the base table is view over multiple
tables.

Inserting a negative value in the autoincrement column of a
partitioned innodb table was causing the value of the auto
increment counter to wrap around into a very large positive
value. The consequences are the same as if a very large positive
value was inserted into a column, e.g. reduced autoincrement
range, failure to read autoincrement counter.
The current patch ensures that before calculating the next
auto increment value, the current value is within the positive
maximum allowed limit.

Modifies the set_auto_increment_if_higher function, to take
into account negative auto increment values when doing a
comparison.
Essentially, Bug#45574 results in this bug. The 'CREATE DATABASE IF NOT EXISTS' statement was not
binlogged, when the database has existed.
Sometimes, the master and slaves become inconsistent. The "CREATE DATABASE
IF NOT EXISTS mysqltest1" statement is not binlogged
if the db 'mysqltest1' existed before the test case is executed.
So the db 'mysqltest1' can't be created on slave.
Patch of Bug#45574 has resolved this problem.
But I think it is better to replace 'mysqltest1' by default db 'test'.
myisamchk tool generates warnings when run on an myisam files (.MYI or .MYD)
This is because of the conversion of max_value for certain options in myisamchk
from singed long to unsigned long
The max value for the options key_buffer_size, read_buffer_size, write_buffer
_size and sort_buffer_size is given as (long) ~0L which becomes -1 when casted
from signed long to longlong and then casted to ulonglong. When (ulonglong) -1
is compared with maximal value for GET_ULONG data type, we adjust it to
(ulonglong) ULONG_MAX and throw the warning.
Fixed by using the right max size.
Max values for the variables (from mysqld.cc)
----------------------------
1. key_buffer_size
5.0: ULONG_MAX
5.1: SIZE_T_MAX
6.0: SIZE_T_MAX
2. read_buffer_size and write_buffer_size
5.0: INT_MAX32
5.1: INT_MAX32
6.0: INT_MAX32
3. sort_buffer_size (aka myisam_sort_buffer_size)
5.0: UINT_MAX32
5.1: ULONG_MAX
6.0: ULONG_MAX
Note: testcase not attached
myisam/myisamchk.c:
Bug#33785 - myisamchk show warning message
Fixed the Max value for key_buffer_size, read_buffer_size, write_buffer_size and
sort_buffer_size options
CREATE TABLE...LIKE...
The mysql server option 'sync_frm' is ignored when table is created with
syntax CREATE TABLE .. LIKE..
Fixed by adding the MY_SYNC flag and calling my_sync() from my_copy() when
the flag is set.
In mysql_create_table(), when the 'sync_frm' is set, MY_SYNC flag is passed
to my_copy().
Note: TestCase is not attached and can be tested manually using debugger.

This fixes the regression introduced in 5.1 that prevents 64 bit builds on Intel while still keeping the core2 hack operational so the cluster can build.
Remove a self assignment.
Rework a few constructs to avoid a potential overflow.
Based upon patch contributed by Michal Hrusecky
storage/ndb/src/kernel/blocks/dbdict/Dbdict.cpp:
Remove self assignment, the object is being initialized.
storage/ndb/src/mgmsrv/InitConfigFileParser.cpp:
Setup the string in a single snprintf.
Failing to connect would release parts of the MYSQL struct.
We would then proceed to try again to connect without re-
initializing the struct.
We prevent the unwanted freeing of data we'll still need now.
client/mysqladmin.cc:
Losing a connection (or not even getting on in the first place) should
not trash the MYSQL-struct.
Add a lot of comments.
Rewrite re-connection fu.

Assert against bad parameters usually caused by de-initing a
MYSQL-struct without re-initing it again before re-use.
