Bug#57113: ha_partition::extra(ha_extra_function):
            Assertion `m_extra_cache' failed

Fix for bug#55458 included DBUG_ASSERTS causing
debug builds of the server to crash on
another multi-table update.

Removed the asserts since they where wrong.
(updated after testing the patch in 5.5).

mysql-test/r/partition.result:
  updated result
mysql-test/t/partition.test:
  Added test for bug#57113
sql/ha_partition.cc:
  Removed the assert for m_extra_cache when
  ::extra(HA_PREPARE_FOR_UPDATE) was called.

Updated according to reviewers comments.

Problem was that the handler call ::extra(HA_EXTRA_CACHE) was cached
but the ::extra(HA_EXTRA_PREPARE_FOR_UPDATE) was not.

Solution was to also cache the other call and forward it when moving
to a new partition to scan.

mysql-test/r/partition.result:
  test result
mysql-test/t/partition.test:
  New test from bug report.
sql/ha_partition.cc:
  cache the HA_EXTRA_PREPARE_FOR_UPDATE just like HA_EXTRA_CACHE.
sql/ha_partition.h:
  Added cache flag for HA_EXTRA_PREPARE_FOR_UPDATE

           INSERT IGNORE ... SELECT ... UNION SELECT ...

This assert was triggered by INSERT IGNORE ... SELECT. The assert checks that a
statement either sends OK or an error to the client. If the bug was triggered
on release builds, it caused OK to be sent to the client instead of the correct
error message (in this case ER_FIELD_SPECIFIED_TWICE).

The reason the assert was triggered, was that lex->no_error was set to TRUE
during JOIN::optimize() because of IGNORE. This causes all errors to be ignored.
However, not all errors can be ignored. Some, such as ER_FIELD_SPECIFIED_TWICE
will cause the INSERT to fail no matter what. But since lex->no_error was set,
the critical errors were ignored, the INSERT failed and neither OK nor the
error message was sent to the client.

This patch fixes the problem by temporarily turning off lex->no_error in
places where errors cannot be ignored during processing of INSERT ... SELECT.

Test case added to insert.test.

read_rnd_buffer_size

Applied the updated description from Paul's patch.

Undo workaround as fix is being merged in

failures on sparc64.

file .\item_subselect.cc, line 836

IN quantified predicates are never executed directly. They are rather wrapped
inside nodes called IN Optimizers (Item_in_optimizer) which take care of the
execution. However, this is not done during query preparation. Unfortunately
the LIKE predicate pre-evaluates constant right-hand side arguments even
during name resolution. Likely this is meant as an optimization.

Fixed by not pre-evaluating LIKE arguments in view prepare mode.

Reverted the ulong->uint diff
Re-applied the first diff.
The original commit message follows:

enum plugin system variables are ulong internally, not int.
On systems where long is not the same as an int it causes
problems. 
Fixed by correct typecasting. Removed the test from the 
experimental list.

Follow-up patch: added test cases for -0 and while

The enum system variables were handled inconsistently 
as ints, unsigned int and unsigned long on various places.
This caused problems on platforms on which 
sizeof(int) != sizeof(long).
Fixed by homogenizing the type of the enum variables
to unsigned int, since it's size compatible with the C enum
type. 
Removed the test from the experimental list.

if() treated any non-numeric string as false
Fixed to treat those as true instead
Added some test cases
Fixed missing $ in variable name in include/mix2.inc

Post fix

mysql-test/t/mysqlbinlog.test:
  Updated for Bug#34283

With statement- or mixed-mode logging, "LOAD DATA INFILE" queries
are written to the binlog using special types of log events.
When mysqlbinlog reads such events, it re-creates the file in a
temporary directory with a generated filename and outputs a
"LOAD DATA INFILE" query where the filename is replaced by the
generated file. The temporary file is not deleted by mysqlbinlog
after termination.

To fix the problem, in mixed mode we go to row-based. In SBR, we
document it to remind user the tmpfile is left in a temporary
directory.

Also drop check-testcase if this has been done
Added comment explaining the restart: syntax

Fix compiler warnings.

mysys/stacktrace.c:
  Tag unused parameters.
sql/sql_lex.cc:
  Variable becomes unused in non-debug builds. Also, no need to
  assert the obvious.

mostly because existing test result files were not updated.

In order to be able to check if the set of the grouping fields in a 
GROUP BY has changed (and thus to start a new group) the optimizer
caches the current values of these fields in a set of Cached_item 
derived objects.
The Cached_item_str, used for caching varchar and TEXT columns,
is limited in length by the max_sort_length variable.
A String buffer to store the value with an alloced length of either
the max length of the string or the value of max_sort_length 
(whichever is smaller) in Cached_item_str's constructor.
Then, at compare time the value of the string to compare to was 
truncated to the alloced length of the string buffer inside 
Cached_item_str.
This is all fine and valid, but only if you're not assigning 
values near or equal to the alloced length of this buffer.
Because when assigning values like this the alloced length is 
rounded up and as a result the next set of data will not match the
group buffer, thus leading to wrong results because of the changed
alloced_length.
Fixed by preserving the original maximum length in the 
Cached_item_str's constructor and using this instead of the 
alloced_length to limit the string to compare to.
Test case added.

Fix a regression (due to a typo) which caused spurious incorrect
argument errors for long data stream parameters if all forms of
logging were disabled (binary, general and slow logs).

sql/sql_prepare.cc:
  Add a missing logical NOT operator.

The problem is that the fix Bug#29784 was mistakenly
reverted when updating YaSSL to a newer version.

The solution is to re-apply the fix and this time
actually add a meaningful test case so that possible
regressions are caught.

extra/yassl/taocrypt/src/coding.cpp:
  Fixed buffer allocation to compute the proper maximum
  decoded size: (EncodedLength * 3/4) + 3

  Start the server using the certificate and key that
  triggers the problem.

Problem: The original patch didn't compile on debug_werror
due to wrong format in printf("%d") for size_t variables.

Fix: Adding cast to (int).

/*![:version:] Query Code */, where [:version:] is a sequence of 5 
digits representing the mysql server version(e.g /*!50200 ... */),
is a special comment that the query in it can be executed on those 
servers whose versions are larger than the version appearing in the 
comment. It leads to a security issue when slave's version is larger 
than master's. A malicious user can improve his privileges on slaves. 
Because slave SQL thread is running with SUPER privileges, so it can
execute queries that he/she does not have privileges on master.

This bug is fixed with the logic below: 
- To replace '!' with ' ' in the magic comments which are not applied on
  master. So they become common comments and will not be applied on slave.

- Example:
  'INSERT INTO t1 VALUES (1) /*!10000, (2)*/ /*!99999 ,(3)*/
  will be binlogged as
  'INSERT INTO t1 VALUES (1) /*!10000, (2)*/ /* 99999 ,(3)*/

Also drop check-testcase if this has been done

to mysql-5.1-innodb plugin.

Do not attempt to test the innodb plugin with the embedded server,
it's not supported for now.

Problem: The functions my_like_range_xxx() returned
badly formed maximum strings for Asian character sets,
which made problems for storage engines.

Fix: 
- Removed a number my_like_range_xxx() implementations,
  which were in fact dumplicate code pieces.
- Using generic my_like_range_mb() instead.
- Setting max_sort_char member properly for Asian character sets
- Adding unittest/strings/strings-t.c, 
  to test that my_like_range_xxx() return well-formed 
  min and max strings.

Notes:

- No additional tests in mysql/t/ available.
  Old tests cover the affected code well enough.

InnoDB Plugin 1.0.10 has been released with MySQL 5.1.49.
