Some of the server implementations don't support dates later
than 2038 due to the internal time type being 32 bit.
Added checks so that the server will refuse dates that cannot
be handled by either throwing an error when setting date at
runtime or by refusing to start or shutting down the server if
the system date cannot be stored in my_time_t.
When compressed myisam files are opened, they are always memory mapped
sometimes causing memory swapping problems.
When we mmap the myisam compressed tables of size greater than the memory
available, the kswapd0 process utilization is very high consuming 30-40% of
the cpu. This happens only with linux kernels older than 2.6.9
With newer linux kernels, we don't have this problem of high cpu consumption
and this option may not be required.
The option 'myisam_mmap_size' is added to limit the amount of memory used for
memory mapping of myisam files. This option is not dynamic.
The default value on 32 bit system is 4294967295 bytes and on 64 bit system it
is 18446744073709547520 bytes.
Note: Testcase only tests the option variable. The actual bug has be to
tested manually.

The help text for --init-slave=name:
"Command(s) that are executed when a slave connects to this master".
This text indicate that the --init-slave option is set on a master
server, and the master server passes the option's argument to slave
which connects to it. This is wrong. Actually the --init-slave option
just can be set on a slave server, and then the slave server executes
the argument each time the SQL thread starts.
Correct the help text for --init-slave option as following:
"Command(s) that are executed by a slave server each time the SQL thread starts."
sql/mysqld.cc:
Correct the help text for --init-slave option.
When parsing the service installation parameter in
default_service_handling() make sure the value of the
optional parameter doesn't overwrite it's name.
- Define and pass compile time path variables as pre-processor definitions to
mimic the makefile build.
- Set new CMake version and policy requirements explicitly.
- Changed DATADIR to MYSQL_DATADIR to avoid conflicting definition in
Platform SDK header ObjIdl.h which also defines DATADIR.
The maximum value of the max_join_size variable is set by converting
a signed type (long int) with negative value (-1) to a wider unsigned
type (unsigned long long), which yields the largest possible value of
the wider unsigned type -- as per the language conversion rules. But,
depending on build options, the type of the max_join_size might be a
shorter type (ha_rows - unsigned long) which causes the warning to be
thrown once the large value is truncated to fit.
The solution is to ensure that the maximum value of the variable is
always set to the maximum value of integer type of max_join_size.
Furthermore, it would be interesting to always have a fixed type for
this variable, but this would incur in a change of behavior which is
not acceptable for a GA version. See Bug#35346.
sql/mysqld.cc:
Set max value for type.
not logged
Errors encountered during initialization of the SSL subsystem
are printed to stderr, rather than to the error log.
This patch adds a parameter to several SSL init functions to
report the error (if any) out to the caller. The function
init_ssl() in mysqld.cc is moved after the initialization of
the log subsystem, so that any error messages can be logged to
the error log. Printing of messages to stderr has been
retained to get diagnostic output in a client context.
include/violite.h:
Adding an enumeration for the various errors that can
occur during initialization of the SSL module.
sql/mysqld.cc:
Adding more logging of SSL init errors, and moving
init_ssl() till after initialization of logging
subsystem.
vio/viosslfactories.c:
Define error strings, provide an access method for these
strings, and maintain an error parameter in several funcs
to return the error (if any) to the caller.
for indexes of InnoDB table
Fixes by replacing the PRNG that is used to pick random pages with a
better one.
Also adds a configuration option "innodb_use_legacy_cardinality_algorithm"
to enable the fix only when the option is set.
This patch is from http://bugs.mysql.com/file.php?id=11789
for bug #15936.
On some platforms fenv.h may #undef the min/max macros
defined in my_global.h.
Fixed by moving the #include directive for fenv.h from
mysqld.cc to my_global.h before definitions for min/max.
include/my_global.h:
Moved #include <fenv.h> from mysqld.cc.
sql/mysqld.cc:
Moved #include <fenv.h> to my_global.h.
Both of our own implementations of rint(3) were inconsistent with the
most common behavior of rint() on those platforms that have it: round
to nearest, break ties by rounding to nearest even.
Fixed by leaving just one implementation of rint() in our source tree,
and changing its behavior to match the most common native
implementations on other platforms.
configure.in:
Added checks for fenv.h and fesetround().
include/config-win.h:
Removed the incorrect implementation of rint() for Windows.
include/my_global.h:
Added an rint() implementation for platforms that do not have it.

The SHOW VARIABLES LIKE .../SELECT @@/SELECT ... FROM INFORMATION_SCHEMA.VARIABLES
were assuming that all the system variables are in system charset (UTF-8).
However the variables that are settable through command line will have a different
character set (character_set_filesystem).
Fixed the server to remember the correct character set of basedir, datadir, tmpdir,
ssl, plugin_dir, slave_load_tmpdir, innodb variables; init_connect and init_slave
variables and use it when processing data.

status
The problem appears to be a race condition, when service is being
stopped right after startup. We set the service status to SERVICE_RUNNING
way too early it cannot yet handle stop requests - initialization has
not finished and hEventShutdown that signals server to stop is not yet
created. If somebody issues "net stop MySQL" at this time, MySQL is not
informed about the stop and continues to run as usual, while
NTService::ServiceMain() stucks forever waiting for mysql's "main" thread
to finish.
Solution is to remain in SERVICE_START_PENDING status until after server
initialization is fully complete and only then change the status to
SERVICE_RUNNING. In SERVICE_START_PENDING we do not accept service control
requests, i.e it is not possible to stop service in that time.
sql/mysqld.cc:
Set service status to running after all initialization is complete
sql/nt_servc.cc:
New method SetRunning() to be called by application
to set service status to SERVICE_RUNNING when apllication
has finished initialization.
sql/nt_servc.h:
New method SetRunning() to be called by application
when initialization completes
When running Stored Routines the Status Variable "Questions" was wrongly
incremented. According to the manual it should contain the "number of
statements that clients have sent to the server"
Introduced a new status variable 'questions' to replace the query_id
variable which currently corresponds badly with the number of statements
sent by the client.
The new behavior is ment to be backward compatible with 4.0 and at the
same time work with new features in a similar way.
This is a backport from 6.0
mysql-test/r/status2.result:
Added test case
mysql-test/t/status2.test:
Added test case
sql/mysqld.cc:
Introduced a new status variable 'questions' to replace the query_id
variable which currently corresponds badly with the number of statements

sql/sql_class.h:
Introduced a new status variable 'questions' to replace the query_id
variable which currently corresponds badly with the number of statements
sent by the client.
sql/sql_parse.cc:
To be backward compatible with 4.0 and at the same time extend the
interpretation of the Question variable, it should be increased on
all COM-commands but COM_STATISTICS, COM_PING, COM_STMT_PREPARE,
COM_STMT_CLOSE and COM_STMT_RESET.
Since COM_QUERY can process multiple statements, there has to be an
extra increase there as well.
sql/sql_show.cc:
Removed deprecated SHOW_QUESTION status code.
sql/structs.h:
Removed deprecated SHOW_QUESTION status code.
test_if_data_home_dir fixed to look into real path.

- Replace per-thread signal()'s with SetUnhandledExceptionFilter().
The only remaining signal() is for SIGABRT (default abort()
handler in VS2005 is broken, i.e removes user exception filter)
- remove MessageBox()'es from error handling code
- Windows port for print_stacktrace() and write_core()
- Cleanup, removed some unused functions
sql/CMakeLists.txt:
Implement stack tracing on and generating crash dumps on Windows
sql/mysqld.cc:
Correct signal handling on Windows.
- For console events, like CTRL-C use SetConsoleCtrlHandler
- For exceptions like access violation, use SetUnhandledExceptionFilter
- For SIGABRT generate exception via __debugbreak() intrinsic
if built with VS2005 and later , since default SIGABRT handler
replaces unhandled exception filter specified by user
- make provisions to debug exception filter, as it is not trivial
(should be compiled with /DDEBUG_UNHANDLED_EXCEPTION_FILTER)
