a second time". The bug was caused by incompatibility of
negations elimination algorithm and PS: during first statement
execute a subtree with negation was replaced with equivalent
subtree without NOTs.
The problem was that although this transformation was permanent,
items of the new subtree were created in execute-local memory.
The patch adds means to check if it is the first execute of a
prepared statement, and if this is the case, to allocate items
in memory of the prepared statement.
The implementation:
- backports Item_arena from 5.0
- adds Item_arena::is_stmt_prepare(),
Item_arena::is_first_stmt_execute().
- deletes THD::allocate_temporary_pool_for_ps_preparing(),
THD::free_temporary_pool_for_ps_preparing(); they
were redundant.
and adds a few invariants:
- thd->free_list never contains junk (= freed items)
- thd->current_arena is never null. If there is no
prepared statement, it points at the thd.
The rest of the patch contains mainly mechanical changes and
cleanups.

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.
We should allow 19 as length of newly created TIMESTAMP fields.
mysql-test/r/type_timestamp.result:
Added test of TIMESTAMP(19) support.
mysql-test/t/type_timestamp.test:
Added test of TIMESTAMP(19) support.
sql/sql_parse.cc:
add_field_to_list(): TIMESTAMP columns should also support 19 as length since it is
length of 4.1 compatible representation.

mysqld >=4.1.3 will however understand shutdown requests sent by clients <4.1.3.
And mysqld <4.1.3 will understand shutdown requests sent by clients >=4.1.3
(it will ignore the level). Those shutdown level are just PLACEHOLDERS now.
So this change is just to make the 4.1 API suitable before it is frozen. Later
we will actually implement the shutdown levels.
VC++Files/winmysqladmin/main.cpp:
2nd argument to mysql_shutdown()
VC++Files/winmysqladmin/mysql.h:
2nd argument to mysql_shutdown()
VC++Files/winmysqladmin/mysql_com.h:
Several types of shutdown now.
include/mysql_com.h:
SHUTDOWN_DEFAULT is now 0 instead of 255, this saves one test in sql_parse.cc
libmysql/libmysql.c:
correcting mistake (how come that my tests still all worked with this? - should recheck, for curiosity).
sql/sql_parse.cc:
with SHUTDOWN_DEFAULT==0, no need for testing packet_length.
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
their better handling.
mysql-test/r/select.result:
New warnings about truncation occured during conversion to datetime value added due
their better handling. Also tweaked test a bit to made it less ambigious for reader.
mysql-test/r/system_mysql_db.result:
Updated test result because new system tables holding time zone descriptions were
added.
mysql-test/r/timezone.result:
Updated timezone.test to use new system variable which shows system time zone.
Added test of warning which is produced if someone tries to store non-existing (due
falling into spring time-gap) datetime value into TIMESTAMP field.
mysql-test/r/type_datetime.result:
Separated and extended test of values and warnings produced for bad values stored in
DATETTIME fields.
mysql-test/r/type_time.result:
Now we are producing more consistent warning when we are truncating datetime value while
storing it in TIME field.
mysql-test/r/type_timestamp.result:
Separated and extended test of values and warnings produced for bad
values stored in TIMESTAMP fields.
mysql-test/t/select.test:
Updated test to make it less ambigous for reader.
mysql-test/t/timezone.test:
Updated timezone.test to use new system variable which shows system time zone.
Added test of warning which is produced if someone tries to store non-existing (due
falling into spring time-gap) datetime value into TIMESTAMP field.
mysql-test/t/type_datetime.test:
Separated and extended test of values and warnings produced for bad
values stored in DATETTIME fields.
mysql-test/t/type_timestamp.test:
Separated and extended test of values and warnings produced for bad
values stored in TIMESTAMP fields.
scripts/mysql_create_system_tables.sh:
Added creation of tables with time zone descriptions.
Also added descriptions of time zones used in tests.
scripts/mysql_fix_privilege_tables.sql:
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.
sql/item_create.h:
Added creation of CONVERT_TZ function as FUNC_ARG3.
sql/item_timefunc.cc:
Added support of per-thread time zone to NOW-like and FROM_UNIXTIME,
UNIX_TIMESTAMP functions.
Added support for CONVERT_TZ function.
Removed call to str_to_timestamp function which caused non-optimal
behavior in certain cases. Replaced calls to str_to_time() function
with its warning generating analog.
sql/item_timefunc.h:
Added support of per-thread time zone to NOW-like and
FROM_UNIXTIME, UNIX_TIMESTAMP functions.
Added support of CONVERT_TZ function.
sql/lex.h:
Added support of CONVERT_TZ function.
sql/log.cc:
Added support for replication of statements depending on time zone.
sql/mysql_priv.h:
Now including headers with per-thread time zone support functions
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/mysqld.cc:
Added per-thread time zone support initialization.
Added new startup parameter --default-time-zone.
sql/set_var.cc:

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.
sql/sql_insert.cc:
We should set TABLE::in_use member pointing to thread which is called
INSERT DELAYED and not to worker thread.
sql/sql_load.cc:
Field::set_warning() now has one more argument now.
sql/sql_parse.cc:
Resetting THD::time_zone_used variable in the end of query
processing.
sql/sql_select.cc:
Now we are setting TABLE::in_use member for all tables (which assume
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

Server will however still accept shutdown without specified level; so that old
mysqladmin can still shut server down.
I would like your comments on the names of shutdown level which I chose. You
are welcome to propose better names. Please however check WL#709 before.
Reason for the names I propose is to be accurate, thus leaving possibility
for other levels which we may imagine in the future; that's why I have rejected
names like "fast", "smart", "graceful" so far. My position is that WAIT_ALL_BUFFERS
or WAIT_CRITICAL_BUFFERS say what the shutdown does, whereas for "smart", "fast" you
need to remember what it does.
This should be pushed in 4.1.3 but only after your comments.

sql/handler.h:
new code to say "try alter and analyze".

by binlogging some SET ONE_SHOT CHARACTER_SETetc,
which will be enough until we have it more compact and more complete in 5.0. With the present patch,
replication will work ok between 4.1.3 master and slaves, as long as:
- master and slave have the same GLOBAL.COLLATION_SERVER
- COLLATION_DATABASE and CHARACTER_SET_DATABASE are not used
- application does not use the fact that table is created with charset of the USEd db (BUG#2326).
all of which are not too hard to fulfill.
ONE_SHOT is reserved for internal use of mysqlbinlog|mysql and works only for charsets,
so we give error if used for non-charset vars.
Fix for BUG#3875 "mysqlbinlog produces wrong ouput if query uses
variables containing quotes" and BUG#3943 "Queries with non-ASCII literals are not replicated
properly after SET NAMES".
Detecting that master and slave have different global charsets or server ids.
mysql-test/r/rpl_server_id1.result:
it's normal to not run as I have added a test to compare server ids of master and slave
at startup and stop if equal (unless --replicate-same-server-id)

mysql-test/t/user_var.test:
testing if the content of user vars is escaped when mysqlbinlog prints them,
and if the name is backquoted.
sql/lex.h:
new keyword ONE_SHOT
sql/log.cc:
when writing to the binlog, before writing the actual statement, write some SET ONE_SHOT CHARACTER_SET_CLIENT etc
for the slave to know the charset variables (which are important as they affect the inserted data).
sql/log_event.cc:
print charset and collation of user var in mysqlbinlog and SHOW BINLOG EVENTS.
escape the content of the var. Backquote its name.
Will ask Bar to check that using my_charset_bin for escaping is ok.
sql/set_var.cc:
understand SET CHARACTER_SET_CLIENT=10 (don't require a string, accept a number).
Refuse changing of GLOBAL CHARACTER_SET_SERVER/COLLATION_SERVER if binlog or slave,
as it will make the master or slave make wrong assumptions.
A function to catch SET ONE_SHOT on non-charset variables (which is forbidden)
sql/set_var.h:
no_support_one_shot to know if the var supports ONE_SHOT (only charset vars do, soon timezones).

sql/slave.cc:
when I/O slave thread starts, verify that master's and slave charsets match.
And by the way verify that server ids are different.
Don't fail if UNIX_TIMESTAMP() can't be done on master (very old master), that's
not fatal.

after Monty's review.
- Item_param was rewritten.
- it turns out that we can't convert string data to character set of
connection on the fly, because they first should be written to the binary
log.
To support efficient conversion we need to rewrite prepared statements
binlogging code first.
include/my_global.h:
Macro swap(a, b, c) was renamed to resolve name conflict with
String::swap() method.
include/my_sys.h:
Added declaration of escape_string_for_mysql()
include/mysql_com.h:
Removed and moved back: a macro which is visible to libmysql user but
has sence only in prepared statement protocol implementation.
isam/_search.c:
swap -> swap_variables
isam/test2.c:
swap -> swap_variables
libmysql/libmysql.c:
- sub_escape_string moved to mysys/charset.c to be visible in sql/
- few cleanups
myisam/mi_test2.c:

sql/field.cc:
Field::store_time refactored to use TIME_to_string function from time.cc
sql/item.cc:
New implementation of Item_param class:
added support for character sets conversion.
sql/item.h:
Item_param:
- 'state' member introduced instead of many boolean variables.
- put ltime, int_value and real_value into union to save space.
- remove unimplemented members
- set_value renamed to set_str
sql/item_timefunc.cc:
Refactored to use functions from time.cc
sql/lock.cc:
rename: swap -> swap_variables
sql/mysql_priv.h:
- added declarations for TIME_to_ulonglong_*, TIME_to_string functions
- const specifiers for make_date, make_time, make_datetime arguments
sql/opt_range.cc:
rename: swap -> swap_variables
sql/protocol.cc:
- added character set conversion support to binary protocol.
- Protocol::convert changed to point at shared buffer in THD.
This lets us use one convert buffer for binary and simple protocol.
The same buffer is used for client->server conversions in prepared
statements code.
- string conversion code refactored to Protocol::store_string_aux function.
- few more comments
sql/protocol.h:
- Protocol::convert now points at THD::convert_buffer: we want to share one
buffer between all protocol implementations.
sql/sql_class.cc:
- implementation of THD::convert_string using THD::convert_buffer
(conversion of strings allocated in the system heap).
sql/sql_class.h:
- THD::convert_buffer is shared between THD and network Protocols and
used for character set conversion of strings.
- new function to convert String object from one charset to another using
THD::convert_buffer
sql/sql_insert.cc:
A little fix in a comment.
sql/sql_parse.cc:
Shrink convert buffer in the end of each statement.
sql/sql_prepare.cc:
Many changes:
- static specifier for set_param_* family of functions.
- FIELD_TYPE -> MYSQL_TYPE
- added set_param_binary as handler for BLOB types.
- added character set support
- added support for param typecode in mysql_stmt_get_longdata
(mysql_stmt_send_long_data handler)
- changes in Item_param deployed
- few cleanups
sql/sql_select.cc:
rename: swap -> swap_variables
sql/sql_string.cc:
- String::append rewritten to support character set conversion for
single-byte encodings.
- added String::swap method to efficiently exchange two string objects.
sql/sql_string.h:
Declraration for String::swap().
sql/time.cc:
- function TIME_to_string to convert TIME to String in default MySQL format
- family of functions TIME_to_ulonglong_*
