does not work well together". Now using simplier and more correct
implementation of st_lex::unlink_first_table()/link_first_table_back()
(It also nicely handles case when global table list is created because
of implictly used time zone tables). (2nd attempt)
Fix for bug #7705 "CONVERT_TZ() crashes with subquery/WHERE on index
column". Implemented new approach for caching objects for constant
time zone arguments. Now instead of determining whenever these arguments
are constants and performing time zone lookup at fix_fields() stage, we
do it on first get_date() invocation.
Cleanup of global @@time_zone variable handling.
mysql-test/r/timezone2.result:
Added test for bugs #7705 "CONVERT_TZ() crashes with subquery/WHERE on
index column" and #7899 "CREATE TABLE .. SELECT .. and CONVERT_TZ()
function does not work well together".
mysql-test/t/timezone2.test:
Added test for bugs #7705 "CONVERT_TZ() crashes with subquery/WHERE on
index column" and #7899 "CREATE TABLE .. SELECT .. and CONVERT_TZ()
function does not work well together".
sql/item_timefunc.cc:
Item_func_convert_tz():
New approach for caching objects for constant time zone arguments.
Now instead of determining whenever these arguments are constants
and performing time zone lookup at fix_fields() stage, we do it
on first get_date() invocation. This works better in cases when
const_item() for these arguments returns true only on get_date()
stage but not on fix_fields() stage (e.g. this happens in quries
with joins or derived tables).
sql/item_timefunc.h:
Item_func_convert_tz():
Added from_tz_cached/to_tz_cached members indicating whenever we
already have Time_zone object representing one of constant time zone
arguments.
sql/set_var.cc:
Cleaned up global @@time_zone variable handling. Now we use proper
locking when we are setting or reading its value.
sql/set_var.h:
Removed declaration of sys_var_thd_time_zone::get_tz_ptr() method, which
no longer used.
sql/sql_lex.cc:
st_lex::unlink_first_table(), st_lex::link_first_table_back():
Simplify implementation according to Monty's suggestion.
Instead doing something special if global and local table lists
are the same, we simply save/restore pointers to first elements
of both global and local lists (which works even when this lists
are the same!). This handles nicely the case when we have separate
global table list becuase time zone tables are implicitly used.
sql/tztime.cc:
Backport of Monty's fixes from 5.0, which give us nicer error messages
if we haven't found time zone with such name or its description.
mysql.time_zone* tables".
We are excluding implicitly used time zone tables from privilege
checking.
mysql-test/r/timezone2.result:
Added test for bug #6116 "SET time_zone := ... requires access to
mysql.time_zone tables"
mysql-test/t/timezone2.test:
Added test for bug #6116 "SET time_zone := ... requires access to
mysql.time_zone tables"
sql/sql_parse.cc:
check_table_access(): we should avoid privilege checking for implicitly
used time zone tables.
sql/tztime.cc:
Indicated dependancy between my_tz_get_table_list() function and
my_tz_check_n_skip_implicit_tables() function.
sql/tztime.h:
Added my_tz_check_n_skip_implicit_tables() function which allows easily
determine whenever we have found beggining of the list of implicitly used
time zone tables and fast-forward to its end.
Fixed bug in end space handle for WHERE text_column="constant"
heap/hp_hash.c:
Optimzations (no change of logic)
libmysql/libmysql.c:
Added missing casts (portability fix)
myisam/mi_key.c:
Changed macro to take arguments and not depend on local variables
Simple indentation fixes ?

sql/field.cc:
Removed not used variable
Portability fix (cast)
Simplified Field_str::double()
Simple indentation cleanups
sql/field.h:
Removed not needed class variable
sql/item_cmpfunc.cc:
Indentation fix
sql/item_strfunc.cc:
Use on stack variable for Item_str_func::val() instead of str_value.
This makes it safe to use str_value inside the Item's val function.
Cleaned up LEFT() usage, thanks to the above change
sql/item_sum.cc:
Indentation cleanups
sql/protocol.cc:
Added missing cast
sql/sql_acl.cc:
Indentatin cleanups.
Added missing cast
Simple optimization of get_sort()
sql/sql_select.cc:
Don't use 'ref' to search on text field that is not of type BINARY (use 'range' instead).
The reson is that for 'ref' we use 'index_next_same' to read the next possible row.
For text fields, rows in a ref may not come in order, like for 'x', 'x\t' 'x ' (stored in this order) which causes a search for 'column='x ' to fail
sql/tztime.cc:
Simple cleanup
strings/ctype-bin.c:
Comment fixes
strings/ctype-mb.c:
Changed variable names for arguments
Instead of trying to open time zone tables during calculation of CONVERT_TZ() function
or setting of @@time_zone variable we should open and lock them with the rest of
statement's table (so we should add them to global table list) and after that use such
pre-opened tables for loading info about time zones.
mysql-test/r/timezone2.result:
Added test for bug #4508
mysql-test/t/timezone2.test:
Added test for bug #4508
scripts/mysql_create_system_tables.sh:
Added one more test time zone to time zone tables which is needed for test for bug #4508.
sql/item_create.cc:
CONVERT_TZ() now is treated as special function.
sql/item_create.h:
CONVERT_TZ() now is treated as special function.
sql/item_timefunc.cc:
Item_func_convert_tz now uses list of pre-opened time zone tables instead of trying to
open them ad-hoc. Also it avoid calling of current_thd.
sql/item_timefunc.h:
Added comment describing special nature of CONVERT_TZ() function.
Optimization: Added own fix_fields() method and tz_tables member for caching pointer
to list of open time zone tables to Item_func_convert_tz class.
sql/lex.h:
CONVERT_TZ() now is treated as special function.
sql/mysql_priv.h:
Removed function which is no longer used.
sql/set_var.cc:
Now my_tz_find() accepts list of pre-opened time zone tables as last argument
and no longer needs pointer to current THD.
sql/set_var.h:
Exported sys_time_zone, which is now used in sql_yacc.yy for quick finding out if we are
setting @@time_zone variable.
sql/sql_base.cc:
Moved propagation of pointers to open tables from global list to local select lists to
open_and_lock_tables(), also added implicit usage of time zone tables as condition for
such propagation.
sql/sql_lex.cc:
Added fake_time_zone_tables_list which is used to indicate that time zone tables are
implicitly used in statement.
st_select_lex_unit::create_total_list(): if time zone tables are implicitly used in
statement add them to global tables list.
sql/sql_lex.h:
Added LEX::time_zone_tables_used member which is used to indicate that time zone tables
are implicitly used in this statement (by pointing to fake_time_zone_table_list) and
for holding pointer to those tables after they've been opened.
sql/sql_parse.cc:
We should also create global table list if statement uses time zone tables implicitly.
Added initialization of LEX::time_zone_tables_used to mysql_query_init().
sql/sql_prepare.cc:
We should also create global table list if statement uses time zone tables implicitly.
sql/sql_select.cc:
Removed functions which are no longer used.
sql/sql_yacc.yy:
CONVERT_TZ() and @@time_zone variable are handled in special way since they implicitly
use time zone tables.
sql/tztime.cc:
Fix for bug #4508 "CONVERT_TZ() function with new time zone as param crashes server".
If statement uses CONVERT_TZ() function or @@time_zone variable is set then it implicitly
uses time zone tables. We need to open and lock such tables with all other tables of
such statement.
All code responsible for opening table was removed from tz_load_from_db() and function was
renamed to tz_load_from_open_tables() (which uses list of pre-opened tables).
We also have new functions for construction and initialization of table list of time
zone tables.
my_tz_find() now always require list of pre-opened time zone tables and no longer needs
current THD. So we have to pre-open them in my_tz_init().
Also now we try to open time zone tables only if they were found during startup.
sql/tztime.h:
New function for construction of table list of time zone tables my_tz_get_table_list().
Now my_tz_find() requires list of pre-pened time zone tables instead of current thread.
the second is for the rest of time declarations in mysys.
include/my_time.h:
New declarations moved from mysql_time.h
include/mysql_time.h:
New declarations moved to my_time.h.
sql/tztime.cc:
Enforcing Monty's approach to header files.
sql/tztime.h:
Enforcing Monty's approach to header files: everything is included in
one place.
(table opened in my_tz_init, was removed from thd->open_tables in
tz_load_from_db w/o being unlocked, so it was stayng in open_cache
forever preventing the latter from being free'd in table_cache_free)
problems with unresolved dependancies on some platforms.
sql/mysql_priv.h:
Moved my_time_t definitions to tztime.h to avoid mysql_tzinfo_to_sql dependancy
on mysql_priv.h.
sql/tztime.cc:
Removed mysql_tzinfo_to_sql dependancy from mysql_priv.h
sql/tztime.h:
Moved my_time_t definitions to tztime.h to avoid mysql_tzinfo_to_sql dependancy
on mysql_priv.h.

tests/client_test.c:
- a test case for Bug#4030 "Client side conversion string -> date type
doesn't work (prepared statements)"
Now we are using time zone abbreviations in debug builds or in utlities only.
Tried to remove warnings generated by compiler by using more proper types for
members of time zone describing structures. Removed unused variables.
Fixed test_time to be able to build on FreeBSD without much problems.
Portability fix: resolved ambiguity of abs() function.
Added basic per-thread time zone functionality (based on public
domain elsie-code). Now user can select current time zone
(from the list of time zones described in system tables).
All NOW-like functions honor this time zone, values of TIMESTAMP
type are interpreted as values in this time zone, so now
our TIMESTAMP type behaves similar to Oracle's TIMESTAMP WITH
LOCAL TIME ZONE (or proper PostgresSQL type).
WL#1266 "CONVERT_TZ() - basic time with time zone conversion
function".
Fixed problems described in Bug #2336 (Different number of warnings
when inserting bad datetime as string or as number). This required
reworking of datetime realted warning hadling (they now generated
at Field object level not in conversion functions).
Optimization: Now Field class descendants use table->in_use member
instead of current_thd macro.
include/my_global.h:
Added macro for reading of 32-bit ints stored in network order from
unaligned memory location.
include/mysqld_error.h:
Added error-code for invalid timestamp warning and error-code
for wrong or unknown time zone specification.
libmysqld/Makefile.am:
Added main per-thread time zone support file to libmysqld
libmysqld/lib_sql.cc:
Added initialization of time zones infrastructure to embedded server.
mysql-test/r/connect.result:
Updated test result since now mysql database contains more
system tables.
mysql-test/r/date_formats.result:
Now when truncation occurs during conversion to datetime value we are producing Warnings
instead of Notes. Also we are giving more clear warnings about this in some cases.
mysql-test/r/func_sapdb.result:
New warnings about truncation occured during conversion to datetime value added due
their better handling.
mysql-test/r/func_time.result:
New warnings about truncation occured during conversion to datetime value added due

Added mysql.time_zone* tables family.
sql/Makefile.am:
Added files implementing time zone support to server, also added
rules for building of mysql_tzinfo_to_sql converter and test_time
test.
sql/field.cc:
Now we are using per-thread time zone for TIMESTAMP <-> whatever conversion.
Fixed generation of warnings for datetime types (DATETIME/TIMESTAMP/DATE/...) and
any other Field to datetime conversion (now we are generating warnings no in lower
level functions like in str_to_TIME() but in Field methods. This allows generate
better and more consistent warnings and to reuse code of str_to_TIME() outside of
server).
Added 3rd parameter to set_warning() method to be able to not increment cut fields
but still produce a warning. Also added set_datetime_warning() family of auxiliary
methods which allow easier generate datetime related warnings.
Also replaced occurences of current_thd with table->in_use member, added
asserts for catching all places there we need to set table->in_use
accordingly. Renamed fix_datetime() function to number_to_TIME() and
moved it to sql/time.cc there it fits better.
sql/field.h:
Added comment about places where we can use table->in_use member
instead of current_thd.
Added 3rd parameter to Field::set_warning() method and set_datetime_warning()
family of methods.
sql/field_conv.cc:
Field::set_warning() method with 2 arguments was replaced with more
generic set_warning() method with 3 arguments.
sql/ha_berkeley.cc:
Now we set table->in_use for temporary tables so we have to use
table->tmp_table for checking if table is temporary.
sql/item.cc:
Replaced calls to str_to_time() and str_to_TIME() funcs with their warning
generating analogs.
sql/item_create.cc:
Added creation of CONVERT_TZ function as FUNC_ARG3.

Added support of per-thread time zone to NOW-like and
FROM_UNIXTIME, UNIX_TIMESTAMP functions.
Added support of CONVERT_TZ function.

and classes. Added portable replacement of time_t - my_time_t type.
Added time zone as one of query distinguishing parameters for
query cache.
Fixed declarations of str_to_TIME, str_to_time and
my_system_gmt_sec (former my_gmt_sec) since now they have one more
out parameter which informs about wrong datetime value or data
truncation during conversion.
Added warning generating version of str_to_TIME() and str_to_time()
functions.
Thrown away str_to_datetime/timestamp functions since they are not
needed any longer. Added number_to_TIME function.

sql/slave.cc:
In order to support replication of statements using time zones in 4.1 we should
ensure that both master and slave have same default time zone.
sql/sql_base.cc:
Now we are setting TABLE::in_use member for all tables (which assume
calls to Field::store or val_ methods).
sql/sql_cache.cc:
Added time zone as one more query distinguishing parameter
for query cache.
sql/sql_class.cc:
Added THD::time_zone_used variable indicating that this query
uses per thread time zone.
sql/sql_class.h:
Added per-thread time zone variable. Added THD::time_zone_used
variable indicating that this query uses per thread time zone
so if this is updating query the time zone should be logged to
binlog.

calls to Field::store or val_ methods).
sql/sql_show.cc:
Now using per thread time zone for extended show tables.
sql/time.cc:
Added support for per-thread time zones for TIMESTAMP type and
reworked generation of warnings for TIMESTAMP and DATETIME types.
(Introduced new TIME_to_timestamp() function. Removed hours
normalisation from former my_gmt_sec() since it was not working
and not used anywhere now, but breaks parameter constness, added
to this function generation of warning if we are falling in spring
time-gap. Removed str_to_timestamp and str_to_datetime functions
which are no longer used. Moved fix_datetime function from
sql/field.cc to this file as number_to_TIME() function. Added
out parameter for str_to_TIME and str_to_time functions which
indicates if value was truncated during conversion, removed direct
generation of warnings from this functions.)
sql/unireg.cc:
Now we are setting TABLE::in_use member for all tables (which assume
calls to Field::store or val_ methods).
BitKeeper/etc/ignore:
Added sql/test_time sql/mysql_tzinfo_to_sql libmysqld/tztime.cc to the ignore list
