result set metadata we need to use virtual select_result::send_fields,
and not address protocol directly, because select_result descendents may
intercept result set (it's the case for example for SELECT INTO OUTFILE).
sql/sql_class.h:
A fix for bug#6059 "mysql_stmt_field_count returns positive numbers
when no resultset is available": introducing select_result::field_count()
method to report actual number of fields in a result set, if any result
set is sent to client.

intercept result set (it's the case for example for SELECT INTO OUTFILE).
Now we need to always have lex->result set if we're in prepared statements.

crashes server." The fix makes Item_func_rand prepared-statements
aware plus it fixes the case when RAND is used in prepared
statements and replication is on (as well as several similar issues).
Until now we did not reset THD before every execution of a prepared

or thd->rand_used they would not be reset until next mysql_parse.

Normally this should have been added to just one place, but
we have to reset thd before assigning placeholders from variables,
thus we can't do that in execute_stmt (yuck).

with memory roots in THD/Statement/Item_arena.
Added assertions preventing memory allocation on bzero'ed MEM_ROOT since it is worked by
pure luck and was very ineffective.
include/my_sys.h:
Reimplementation of Monty's optimization of clear_alloc_root().
Now clear_alloc_root() can be used only for detaching memory associated with MEM_ROOT
(e.g. to avoid its freeing). It can not be used for MEM_ROOT initialization any longer
(it was bad idea anyway since memory allocation on such MEM_ROOT was very ineffective
and worked by pure luck).
Introduced ALLOC_ROOT_MIN_BLOCK_SIZE constant.
mysys/my_alloc.c:
Added description of init_alloc_root().
Added assertions to alloc_root() and reset_root_defaults() so now they can only be used
on previosly initialized MEM_ROOT. (It worked for bzeroed MEM_ROOT before but
by pure luck and very inefficiently). Calling free_root() on bzero'ed MEM_ROOT
is still ok (we can't remove this easily because of static MEM_ROOTs).
Also now using ALLOC_ROOT_MIN_BLOCK_SIZE constant inside these functions.
sql/opt_range.cc:
Fixed get_quick_select_for_ref() function to not use bzero'ed MEM_ROOT for allocation.
Also QUICK_RANGEs created in this function should be created in memory root of QUICK_SELECT.
sql/sql_class.cc:
Implementation of Monty's idea about clear_alloc_root() optimization and cleanup of work
with memory roots in THD/Statement/Item_arena.
Now we are always initing THD::transaction.mem_root and THD::mem_root in THD constructor
(without memory allocation and with minimal block size) and then later change their
parameters in THD::init_for_queries() (this is partially because we can't allocate anything
on bzero'ed memory roots anymore).
Item_arena() constructor is now trivial and is used only then Item_arena is created as backup
storage for other Item_arena (we use Item_arena(bool) now if it is part of Statement).
Both trivial Item_arena constructor and destructor are now inline.
Removed unneeded clear_alloc_root from Item_arena::restore_backup_item_arena().
sql/sql_class.h:
Both trivial Item_arena constructor and destructor are now inline.
Commented various Item_arena constructors.

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.

Bug #4810 "deadlock with KILL when the victim was in a wait state"
(I included mutex unlock into exit_cond() for future safety)
and BUG#4827 "KILL while START SLAVE may lead to replication slave crash"
sql/lock.cc:
we did exit_cond() before unlock(LOCK_open), which led to deadlocks with THD::awake(). Fixing this.
sql/log.cc:
mutex unlock is now included in exit_cond()
sql/repl_failsafe.cc:
we did exit_cond() before unlock(LOCK_rpl_status), which led to deadlocks with THD::awake(). Fixing this.
sql/slave.cc:
we did exit_cond() before unlock(cond_lock), which led to deadlocks with THD::awake(). Fixing this.
Fixing also that if killed while waiting for slave thread to start, we don't release the mutex
(that caused a double release of the mutex => crash).
sql/sql_class.h:
comments about exit_cond()/enter_cond().
Mutex unlock is now included in exit_cond() so that it's always done in the good order.
sql/sql_table.cc:
unlock is now included in exit_cond().
sql/sql_class.h:
removing the assertion as I don't want to include assert.h (inclusion of assert.h has already been
reworked in 4.1, so I'll move the assertion to 4.1). Assertion makes compilation fail if non-debug.
happen on SMP machines, when a thread is going to wait on a condition and it is KILLed at the
same time.
Cleaning code a bit by adding a test in enter_cond() that we have the mutex (was already the case in all places
where it's called except one which is fixed here).
sql/log.cc:
safe_mutex_assert_owner() is now in THD::enter_cond()
sql/slave.cc:
lock mutex before waiting on condition.
sql/sql_class.cc:
THD::awake(): before locking the mutex, let's test it's not zero;
in theory indeed, the killer thread may see current_cond non-zero and current_mutex zero
(order of assignments is not guaranteed by POSIX).
A comment noting that there is still a small chance a KILL does not work and needs
being re-issued.
sql/sql_class.h:
Assert in enter_cond() that we have the mutex.
It is already the case in all places where we call enter_cond(), so better ensure it there.

Won't be pushed as is - separate email sent for internal review.
WL#1717 "binlog-innodb consistency".
Now when mysqld starts, if InnoDB does a crash recovery, we use the binlog name
and position retrieved from InnoDB (corresponding to the last transaction
successfully committed by InnoDB) to cut any rolled back transaction from
the binary log. This is triggered by the --innodb-safe-binlog option.
Provided you configure mysqld to fsync() InnoDB at every commit (using
flush_log_at_trx_commit) and to fsync() the binlog at every write
(using --sync-binlog=1), this behaviour guarantees that a master always has
consistency between binlog and InnoDB, whenever the crash happens.
6 tests to verify that it works.
client/mysqltest.c:
New command require_os (only "unix" accepted for now).
innobase/include/trx0sys.h:
when InnoDB does crash recovery, we now save the binlog coords it prints, into variables for later use.
innobase/trx/trx0sys.c:
when InnoDB does crash recovery, we now save the binlog coords it prints, into variables for later use.
mysql-test/mysql-test-run.sh:
The tests which check that the binlog is cut at restart, need to not delete those binlogs, of course.
And not delete replication info, so that we can test that the slave does not receive anything
wrong from the cut binlog.
sql/ha_innodb.cc:
methods to read from InnoDB the binlog coords stored into it
sql/ha_innodb.h:
ethods to read from InnoDB the binlog coords stored into it
sql/log.cc:
Added my_sync() when we create a binlog (my_sync of the binlog and of the index file);
this is always done, whether --sync-binlog or not (binlog creation is rare, so no speed
problem, and I like to have the existence of the binlog always reliably recorded, even if
later content is not).
If --crash-binlog-innodb, crash between the binlog write and the InnoDB commit.
New methods:
- report_pos_in_innodb() to store the binlog name and position into InnoDB (used only when
we create a new binlog: at startup and at FLUSH LOGS)
- cut_spurious_tail() to possibly cut the tail of a binlog based on the info we read
from InnoDB (does something only if InnoDB has just done a crash recovery).
sql/mysql_priv.h:
new option, to crash (use for testing only)
sql/mysqld.cc:
New option --innodb-safe-binlog and --crash-binlog-innodb (the latter is for testing, it makes mysqld crash).
Just after opening the logs and opening the storage engines, cut any wrong statement from the binlog, based
on info read from InnoDB.
sql/sql_class.h:
new methods for MYSQL_LOG.
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:
Added support for per-thread time_zone variable.
Renamed old timezone variable to system_time_zone.
sql/set_var.h:
Added support for per-thread time_zone variable.

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).
