Fixed the following problems:
1. cmake 2.6 warning because of a changed default on
how the dependencies to libraries with a specified 
path are resolved.
Fixed by requiring cmake 2.6.
2. Removed an obsolete pre-NT4 hack including defining
Windows system defines to alter the behavior of windows.h.
3. Disabled warning C4065 on compiling sql_yacc.cc because
of a know incompatibility in some of the newer bison binaries.

without error

When using quick access methods for searching rows in UPDATE or 
DELETE there was no check if a fatal error was not already sent 
to the client while evaluating the quick condition.
As a result a false OK (following the error) was sent to the 
client and the error was thus transformed into a warning.

Fixed by checking for errors sent to the client during 
SQL_SELECT::check_quick() and treating them as real errors.

Fixed a wrong test case in group_min_max.test
Fixed a wrong return code in mysql_update() and mysql_delete()

  sort_buffer_size cannot allocate

The NULL return from tree_insert() (on low memory) was not
checked for in Item_func_group_concat::add(). As a result
on low memory conditions a crash happens.

Fixed by properly checking the return code.

GHz.

The crash happend because for views which are joins
we have table_list->table == 0 and 
table_list->table->'any method' call leads to crash.
The fix is to perform table_list->table->file->extra()
method for all tables belonging to view.


mysql-test/r/view.result:

sql/sql_insert.cc:
  added prepare_for_positional_update() function
  which updates extra info about primary key for
  tables belonging to view.

Details:
- Add "sync_slave_with_master" at test end
- Restore the initial value of log_bin_trust_function_creators

without proper formatting
      
The problem is that a suitably crafted database identifier
supplied to COM_CREATE_DB or COM_DROP_DB can cause a SIGSEGV,
and thereby a denial of service. The database name is printed
to the log without using a format string, so potential
attackers can control the behavior of my_b_vprintf() by
supplying their own format string. A CREATE or DROP privilege
would be required.
      
This patch supplies a format string to the printing of the
database name. A test case is added to mysql_client_test.


sql/sql_parse.cc:
  Added format strings.
tests/mysql_client_test.c:
  Added new test case.

                               But Should Be "Zero Rows"


After applying the innodb snapshot 5.0-ss5406 for bug#40565, the windows push build
tests failed because of the missing cast of void * pointer in row0sel.c file

Informed the innodb developers and received patch by email.

innobase/row/row0sel.c:
  Cast the default_rec which is a void * pointer

BUG#38479 - valgrind warnings in show table status for innodb tables

Detailed revision comments:

branches/5.0:

Fix Bug#38479 valgrind warnings in show table status for innodb tables

by initializing prebuilt->hint_need_to_fetch_extra_cols.

  Details:
  - Limit the queries to character sets and collations
    which are most probably available in all build types.
    But try to preserve the intention of the tests.
  - Remove the variants adjusted to some build types.

  Note:
  1. The results of the review by Bar are included.
  2. I am not able to check the correctness of this patch
     on any existing build type and any MySQL version.
     So it could happen that the new test fails somewhere.

occasionally.

mysql_multi can call mysqld_safe. In doing this it's not changing the 
current working directory. This may cause confusion in the case where 
mysqld_multi is handling instances of servers of different versions 
and the current working directory is the installation directory of one 
of these servers.

Fixed by enhancing the meaning of basedir in [mysqldN] sections of 
mysqld_multi. If specified, mysqld_multi will change the current 
working directory to the basedir directory before starting the server 
in mysqld_multi ... start ... and then change it back to what it was.

  Bug #36654: optionally preserve, change and restore the cwd when 
  starting server instances

      
Failure to allocate memory for the hash->array element,
caused hash_init to return without initializing the other
members of the hash. Thus although the dynamic array
buffer may be allocated at a later point in the code, the
incompletely initialized hash caused fatal failures.

This patch moves the initialization of the other members
of the hash above the array allocation, so that the usage
of this hash will not result in fatal failures.

include/hash.h:
  Bug#43572 Handle failures from hash_init
  
  hash_inited is used to verify that the hash is
  valid. After the change induced by the current
  patch hash->array.buffer !=0 is not a valid check
  for this condition, since, the dynamic array can
  be allocated even at a later time. Bootstrap SQL
  script is setting some variables, which are
  actually not set due to this hash_inited issue.
  Thus we get empty grant tables.
  
  A better way to check if the hash is valid is
  to verify that hash->blength is greater than 0.
mysys/hash.c:
  Bug#43572 Handle failures from hash_init
  
  Move the initialization of the other members
  of the hash above the array allocation, so that
  the usage of this hash will not result in fatal
  failures.

      
Inconsistent behavior of session variable max_allowed_packet 
(and net_buffer_length); only assignment to the global variable 
has any effect, without this being obvious to the user.
      
The patch for Bug#22891 is backported to 5.0, making the two
session variables read-only. As this is a backport to GA 
software, the error used when trying to assign to the read-
only variable is ER_UNKNOWN_ERROR. The error message is the 
same as in 5.1+.

mysql-test/t/variables.test:
  Tests are changed to account for the new semantics, and assignment to the read-only variables is added to test 
  the emission of the correct error message.
sql/set_var.cc:
  Both max_allowed_packet and net_buffer_length are changed 
  to be of type sys_var_thd_ulong_session_readonly. ER_UNKNOWN_ERROR is used to indicate an attempt to assign 
  to an instance of a read-only variable.
sql/set_var.h:
  Class sys_var_thd_ulong_session_readonly is added.

 
Change the default optimization level for Sun Studio to "-O1". 
This is a workaround for a Sun Studio bug (see bug #41710 
comments for details): 
 
1. Use $GCC instead of $ac_cv_prog_gcc to check for gcc, since 
the first one is the only documented way to do it. 
 
2. Use $GXX instead of $ac_cv_prog_cxx_g to check for g++, 
since the latter is set to "yes" when the C++ compiler accepts 
"-g" which is the case for both g++ and CC. 
 
3. When building with Sun Studio, set the default values for 
CFLAGS/CXXFLAGS to "-O1", since unlike GCC, Sun Studio 
interprets "-O" as "-xO3" (see the manual pages for cc and CC).

with gcc 4.3.2
      
Compiling MySQL with gcc 4.3.2 and later produces a number of 
warnings, many of which are new with the recent compiler
versions.
                  
This bug will be resolved in more than one patch to limit the
size of changesets. This is the second patch, fixing more
of the warnings.
