121e04732e Bug #52315: utc_date() crashes when system time > year 2037
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.

412798658a BUG#51866 - crash with repair by sort and fulltext keys
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.

  A test case for BUG#51866.

  A test case for BUG#51866.
sql/mysqld.cc:
  Min value for myisam_sort_buffer_size is 4096.
storage/myisam/mi_check.c:
  When estimating number of index entries for external
  fulltext parser, take into account that key_length may
  be bigger than myisam_sort_buffer_size. Reuse logic
  from _create_index_by_sort(): force MIN_SORT_BUFFER to
  be min value for myisam_sort_buffer_size.
  
  Another problem is that ftkey_nr has no other meaning
  than serial number of fulltext index starting with 1.
  We can't say if this key using built-in or external
  parser basing on it's value. In other words we always
  entered if-branch for external parser. At this point,
  the only way to check if we use default parser is to
  compare keyinfo::parser with &ft_default_parser.
storage/myisam/sort.c:
  Get rid of MIN_SORT_MEMORY, use MIN_SORT_BUFFER instead
  (defined in myisamdef.h, has the same value and purpose).

cf9966f86f Fix for Bug#37408 - Compressed MyISAM files should not require/use mmap()
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.

37d2019d17 Bug #32223 SETting max_allowed_packet variable
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.

06142cd545 Bug #42778: delete order by null global variable causes
assertion .\filesort.cc, line 797

A query with the "ORDER BY @@some_system_variable" clause,
where @@some_system_variable is NULL, causes assertion
failure in the filesort procedures.

The reason of the failure is in the value of
Item_func_get_system_var::maybe_null: it was unconditionally
set to false even if the value of a variable was NULL.

1e37c919ef Fix for BUG#10206 - InnoDB: Transaction requiring Max_BinLog_Cache_size > 4GB
always rollsback.

The global variable max_binlog_cache_size cannot be set more than 4GB on
32 bit systems, limiting transactions of all storage engines to 4G of changes.

The problem is max_binlog_cache_size is declared as ulong which is 4 bytes
on 32 bit and 8 bytes on 64 bit machines.

Fixed by using ulonglong for max_binlog_cache_size which is 8bytes on 32 
and 64 bit machines.The range for max_binlog_cache_size on 32 bit and 64 bit
systems is 4096-18446744073709547520 bytes.

5867396a8d Bug#36446: Attempt to set @@join_buffer_size to its minimum value produces spurious warning
If a sys-var has a base and a block-size>1, and then a
user-supplied value >= minimum ended up below minimum
thanks to block-size alignment, we threw a warning.
This meant for instance that when getting, then setting
the minimum, we'd see a warning. This was needlessly
confusing. (updated patch)

402bc523b2 Bug#36540: CREATE EVENT and ALTER EVENT statements fail with large server_id
The problem is that creating a event could fail if the value of
the variable server_id didn't fit in the originator column of
the event system table. The cause is two-fold: it was possible
to set server_id to a value outside the documented range (from
0 to 2^32-1) and the originator column of the event table didn't
have enough room for values in this range.

The log tables (general_log and slow_log) also don't have a proper
column type to store the server_id and having a large server_id
value could prevent queries from being logged.

The solution is to ensure that all system tables that store the
server_id value have a proper column type (int unsigned) and that
the variable can't be set to a value that is not within the range.

d1fb6bbcc8 Bug#40657: assertion with out of range variables and traditional sql_mode
In STRICT mode, out-of-bounds values caused an error message
to be queued (rather than just a warning), without any further
error-like processing happening. (The error is queued during
update, at which time it's too late. For it to be processed
properly, it would need to be queued during check-stage.)
The assertion rightfully complains that we're trying to send
an OK while having an error queued.

Changeset breaks a lot of tests out into check-stage. This also
allows us to send more correct warnings/error messages.

f92c573145 Bug#28234 - global/session scope - documentation vs implementation
Several system variables did not behave like system variables should do.
When trying to SET them or use them in SELECT, they were reported as
"unknown system variable". But they appeared in SHOW VARIABLES.

This has been fixed by removing the "fixed_vars" array of variables
and integrating the variables into the normal system variables chain.
All of these variables do now behave as read-only global-only
variables. Trying to SET them tells they are read-only, trying to
SELECT the session value tells they are global only. Selecting the
global value works. It delivers the same value as SHOW VARIABLES.

e5ae4e2392 A fix for Bug#22891 "session level max_allowed_packet can be
set but is ignored".
                                  
This patch makes @@session.max_allowed_packed and
@@session.net_buffer_length read-only as suggested in the bug
report. The user will have to use SET GLOBAL (and reconnect)
to alter the session values of these variables.
                            
The error string ER_VARIABLE_IS_READONLY is introduced.
                            
Tests are modified accordingly.


sql/set_var.cc:
  The class sys_var_thd_ulong_session_readonly is introduced as
  a specialization of sys_var_thd_ulong implementing a read-only
  session variable. The class overrides check() and
  check_default() to achieve the read-only property for the
  session part of the variable.

6d54b0443a Bug #32124: crash if prepared statements refer to variables in the where clause
The code to get read the value of a system variable was extracting its value 
on PREPARE stage and was substituting the value (as a constant) into the parse tree.
Note that this must be a reversible transformation, i.e. it must be reversed before
each re-execution.
Unfortunately this cannot be reliably done using the current code, because there are
other non-reversible source tree transformations that can interfere with this
reversible transformation.
Fixed by not resolving the value at PREPARE, but at EXECUTE (as the rest of the 
functions operate). Added a cache of the value (so that it's constant throughout
the execution of the query). Note that the cache also caches NULL values.
Updated an obsolete related test suite (variables-big) and the code to test the 
result type of system variables (as per bug 74).

1fc5777320 Final fix for bug#38349: Did the changes due to the 2 reviews.
- Updated slow_query_log_file_basic and general_log_file basis instead of the func version as
the func version run good but the basic versions fail.
- Sent innodb.test to dev@innodb.com.
- variables.test has differences probably due to a bug in mtr or in the SET statement (see bug#39369).
- general_log_file_basic.test and slow_query_log_file_bsaic.test have differences, which might be 
produced by the new mtr (see bug#38124).

fba9e7c878 A patch for Bug#34820: log_output can be set to illegal value.
We have "set" variables, which can accept empty values
(like sql_mode), and which can not (like log_output). The problem
was that the code does not distinguish them and allow empty
values for every set variable.

The fix is to introduce an attribute of a set variable telling
whether it can accept empty values.

89a208850a Bug#31177: Server variables can't be set to their current values
Default values of variables were not subject to upper/lower bounds
and step, while setting variables was. Bounds and step are also
applied to defaults now; defaults are corrected quietly, values
given by the user are corrected, and a correction-warning is thrown
as needed. Lastly, very large values could wrap around, starting
from 0 again. They are bounded at the maximum value for the
respective data-type now if no lower maximum is specified in the
variable's definition.

6eced1b857 Fix for bug #29131: SHOW VARIABLES reports variable 'log' but SET
doesn't recognize it

This is a 5.0 version of the patch, it will be null-merged to 5.1

Problem:

'log' and 'log_slow_queries' were "fixed" variables, i.e. they showed up
in SHOW VARIABLES, but could not be used in expressions like 
"select @@log". Also, using them in the SET statement produced an 
incorrect "unknown system variable" error.

Solution:

Make 'log' and 'log_slow_queries' read-only dynamic variables to make 
them available for use in expressions, and produce a correct error 
about the variable being read-only when used in the SET statement.


mysql-test/r/variables.result:
  Added a test case for bug #29131.
mysql-test/t/variables.test:
  Added a test case for bug #29131.
sql/mysql_priv.h:

sql/mysqld.cc:
  Changed the type of opt_log and opt_slow_log to my_bool to 
  align with the interfaces in set_var.cc
sql/set_var.cc:
  Made 'log' and 'log_slow_queries' to be read-only dynamic system 
  variable, i.e. available for use in expressions with the @@var syntax.
sql/set_var.h:
  Added a new system variable class representing a read-only boolean
  variable.
