subselect_single_select_engine::exec()
When a subquery doesn't need to be evaluated because
it returns only aggregate functions and these aggregates
can be calculated from the metadata about the table it
was not updating all the relevant members of the JOIN
structure to reflect that this is a constant query.
This caused problems to the enclosing subquery
('<> SOME' in the test case above) trying to read some
data about the tables.
Fixed by setting const_tables to the number of tables
when the SELECT is optimized away.
REORGANIZE PARTITION
There were several problems which lead to this this,
all related to bad error handling.
1) There was several bugs preventing the ddl-log to be used for
cleaning up created files on error.
2) The error handling after the copy partition rows did not close
and unlock the tables, resulting in deletion of partitions
which were in use, which lead InnoDB to put the partition to
drop in a background queue.
sql/ha_partition.cc:
Bug#47343: InnoDB fails to clean-up after lock wait timeout on
REORGANIZE PARTITION
Better error handling, if partition has been created/opened/locked
then make sure it is unlocked and closed before returning error.
The delete of the newly created partition is handled by the ddl-log.

Bug #49984 Test 'rpl_loaddata_symlink' fails with "Could not find target log"
Sometimes the symbolic link is available on Windows if
you have some Unix (emulation) layer installed like
Cygwin, MKS or other. But symbolic link is not always
available. It depends on versions, file volume and
system environment of Windows. And the symbolic link
is not typically used on Windows, at least not in the
degree and style they are used on Unix. We can not
change the test case to do without symbolic link,
because the test case is used to test that if the
symbolic link works fine.
To fix the problem, skip the test on windows.

The test case rpl_binlog_corruption fails on windows because when
adding a line to the binary log index file it gets terminated
with a CR+LF (which btw, is the normal case in windows, but not on
Unixes - LF). This causes mismatch between the relay log names,
causing mysqld to report that it cannot find the log file.
We fix this by creating the instrumented index file through
mysql, ie, using SELECT ... INTO DUMPFILE ..., as opposed on
relying on ultimatly OS commands like: -- echo "..." >
index. These changes go into the file and make the procedure
platform independent:
include/setup_fake_relay_log.inc
Side note: when using SELECT ... INTO DUMPFILE ..., one needs to
check if mysqld is running with secure_file_priv. If it is, we do
it in two steps: 1. create the file on the allowed location;
2. move it to the datadir. If it is not, then we just create the
file directly on the datadir (so previous step 2. is not needed).
Problem was when calculating the range of partitions for
pruning.
Solution was to get the calculation correct. I also simplified
it a bit for easier understanding.

sql/sql_partition.cc:
Bug#49742: Partition Pruning not working correctly for RANGE
Simplified calculation for partition id for ranges.
Easier to get right and understand.
Added comments.
Several problems fixed :
1. Non constant expressions in UNION ... ORDER BY were not correctly cleaned up
in st_select_lex_unit::cleanup() causing crashes in EXPLAIN EXTENDED because of
fields quoted by these expressions pointing to the already freed temporary table
used to calculate the UNION.
Fixed by correctly cleaning up expressions of any depth.
2. Subqueries in the order by part of UNION ... ORDER BY ... caused a crash in
EXPLAIN EXTENDED because of a transformation attempt made during EXPLAIN EXTENDED
execution. Fixed by not doing the transformation when in EXPLAIN.
3. Fulltext functions caused crash when in the ORDER BY part of an un-parenthesized
UNION that gets "promoted" to be valid for the whole union, e.g.
SELECT * FROM t1 UNION SELECT * FROM t2 ORDER BY MATCHES (a) AGAINST ('abc' IN BOOLEAN MODE).
This is a case that demonstrates a more general problem of parts of the query being
moved to another level. When doing such transformation late in the optimization run
when most of the flags about the contents of the query are already aggregated it's possible
to "split" the flags so that they correctly reflect the new queries after the transformation.
In specific the ST_SELECT_LEX::ftfunc_list is holding all the free text function for all the
parts of the second SELECT in the UNION and we don't know what part of that is in the ORDER BY
that we're to move to the UNION level and what part is about the other parts of the second SELECT.
Fixed by throwing and error when such statements are about to be processed by adding a check
for the presence of MATCH() inside the ORDER BY clause that's going to get promoted to UNION.
To workaround this new limitation one must parenthesize the UNION SELECTs and provide a real
global ORDER BY for the UNION outside of the parenthesis.
At the end of execution top level join execution
we cleanup this join with true argument.
It leads to underlying join cleanup(subquery) with true argument too
and to tmp_table_param->field array cleanup which is required later.
The problem is that Item_func_set_user_var does not set
result_filed which leads to unnecessary repeated excution of subquery
on final stage.
The fix is to set result_field for Item_func_set_user_var.

Problem: some (see eq_ref_table()) ORDER BY/GROUP BY optimization
is called before each PS execution. However, we don't properly
initialize its stucture every time before the call.

The check for equality was assuming the field object is always

If first call of the procedure is failed on
the open_table stage stmt_arena->state is set to
EXECUTED state. On second call(if no errors on

thd->stmt_arena->is_stmt_prepare_or_first_sp_execute()
returns FALSE for EXECUTED state. The item is created
not in its own arena and it leads to crash on further

branches/5.1: fix bug#49267: innodb-autoinc.test fails on windows
because of different case mode
There is no change to the InnoDB code, only to fix test case by
changing "T1" to "t1".
The test allowed random coincidence of connection ids for two concurrent
sessions performing CREATE/DROP temp tables.
Fixed with correcting the test. The sessions connection ids are not changed
from their defaults anymore.
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.

returns incorrect results with where
An outer join of a const table (outer) and a normal table
(inner) with GROUP BY on a field from the outer table would
optimize away GROUP BY, and thus trigger the optimization to
do away with a temporary table if grouping was performed on
columns from the const table, hence executing the query with
filesort without temporary table. But this should not be
done if there is a non-indexed access to the inner table,
since filesort does not handle joins. It expects either ref
access, range ditto or table scan. The join condition will
thus not be applied.
Fixed by always forcing execution with temporary table in
the case of ROLLUP with a query involving an outer join. This
is a slightly broader class of queries than need fixing, but
it is hard to ascertain the position of a ROLLUP field wrt
outer join with current query representation.

Bug#47650: Fix
Problem: inserting a record we don't set unused null bits in the
record buffer if no default field values used.
That may lead to wrong live checksum calculation.

- set unused null bits to 1 in the record buffer in case we
don't call restore_record() before a fill_record() call
(when no default values used).
The bug is caused by a race condition between the
INSERT DELAYED thread and the client thread's FLUSH TABLE. The
FLUSH TABLE does not guarantee (as is (wrongly) suggested in the
test case) that the INSERT DELAYED is ever executed. The
execution of the test case will thus not be deterministic.
The fix has been to do a deterministic verification that both
threads are complete by checking the content of the table.
This test case tests a circular replication of four hosts.
A--->B--->C--->D--->A
The replicate is slow and needs more time to replicate all data in the circle.
The time it spends to replicate, sometimes, is longer than the time that
wait_condition.inc spends to wait that all data has been replicated. This
cause sporadical failure of this test case.
This patch uses sync_slave_with_master to ensure that all data can be replicated
successfully in the circle.
int join_read_key(JOIN_TAB*)
The eq_ref access method TABLE_REF (accessed through

Problem: add_collation did not check that cs->number is smaller
than the number of elements in the array all_charsets[],
so server could crash when loading an Index.xml file with
a collation ID greater the number of elements
(for example when downgrading from 5.5).
Fix: adding a condition to check that cs->number is not out of valid range.
'LOAD DATA CONCURRENT [LOCAL] INFILE ...' statment only is binlogged as
'LOAD DATA [LOCAL] INFILE ...' in SBR and MBR. As a result, if replication is on,
queries on slaves will be blocked by the replication SQL thread.
This patch write code to write 'CONCURRENT' into the log event if 'CONCURRENT' option
is in the original statement in SBR and MBR.
timestamp primary key
Since TIMESTAMP values are adjusted by the current time zone
settings in both numeric and string contexts, using any
expressions involving TIMESTAMP values as a
(sub)partitioning function leads to undeterministic behavior of
partitioned tables. The effect may vary depending on a storage
engine, it can be either incorrect data being retrieved or
stored, or an assertion failure. The root cause of this is the
fact that the calculated partition ID may differ from a
previously calculated ID for the same data due to timezone
adjustments of the partitioning expression value.
Fixed by disabling any expressions involving TIMESTAMP values
to be used in partitioning functions with the follwing two
exceptions:
1. Creating or altering into a partitioned table that violates
the above rule is not allowed, but opening existing such tables
results in a warning rather than an error so that such tables
could be fixed.
2. UNIX_TIMESTAMP() is the only way to get a
timezone-independent value from a TIMESTAMP column, because it
returns the internal representation (a time_t value) of a
TIMESTAMP argument verbatim. So UNIX_TIMESTAMP(timestamp_column)
is allowed and should be used to fix existing tables if one
wants to use TIMESTAMP columns with partitioning.

A few problems were found in the fix for bug 43668:
1) Comparison of the YEAR column with NULL always returned TRUE;
2) Comparison of the YEAR column with constants always returned
unpredictable result;
3) Unnecessary conversion warnings when comparing a non-integer
constant with a NULL value in the YEAR column;
The problems described above have been resolved with an
exception: zero (i.e. invalid) YEAR column value comparison
with 00 or 2000 still fail (it is not a regression and it was
not a regression), so MIN/MAX on YEAR column containing zero
value still fail.

sql/item_cmpfunc.cc:
- The get_year_value() function has been modified to make its
return value compatible with the get_datetime_value() return
value (i.e. to convert numeric values into the YYYY0000000000
(YYYY-00-00 00:00:00) form.
- The Arg_comparator::set_cmp_func method has been modified to
use the get_year_value function if get_datetime_value() is not
applicable.
From now only 2 cases have a special processing there:
* both comparing items have MYSQL_TYPE_YEAR field type
or
* one item have is MYSQL_TYPE_YEAR and other one is
is_datetime()-compliant.
- New helper function try_year_cmp_func() has been
added for the better code readability to call from
Arg_comparator::set_cmp_func().
- The Arg_comparator::compare_year method has been removed
since get_year_value() is compatible with the old
Arg_comparator::compare_datetime method that doesn't have
problems #1-#3 (see whole patch entry commentary).
sql/item_cmpfunc.h:

There are three issues that caused rpl_killed_ddl fails sporadically
in pb2:
1) thd->clear_error() was not called before create Query event
if operation is executed successfully.
2) DATABASE d2 might do exist because the statement to CREATE or
ALTER it was killed
3) because of bug 43353, kill the query that do DROP FUNCTION or
DROP PROCEDURE can result in SP not found
This patch fixed all above issues by:
1) Called thd->clear_error() if the operation succeeded.
2) Add IF EXISTS to the DROP DATABASE d2 statement
3) Temporarily disabled testing DROP FUNCTION/PROCEDURE IF EXISTS.

Fixed the SELECT ... ORDER BY .. DESC (it uses a different code path compared
to the ASC that has been fixed with the previous fix).
{PROCEDURE|FUNCTION} FROM ...'
The master would hit an assertion when binary log was
active. This was due to the fact that the thread's diagnostics
area was being cleared before writing to the binlog,
independently of mysql_routine_grant returning an error or
not. When mysql_routine_grant was to return an error, the return
value and the diagnostics area contents would
mismatch. Consequently, neither my_ok would be called nor an
error would be signaled in the diagnostics area, eventually
triggering the assertion in net_end_statement.
We fix this by not clearing the diagnostics area at binlogging
time.
escaped field names
When in mixed or statement mode, the master logs LOAD DATA
queries by resorting to an Execute_load_query_log_event. This
event does not contain the original query, but a rewritten
version of it, which includes the table field names. However, the
rewrite does not escape the field names. If these names match a
reserved keyword, then the slave will stop with a syntax error
when executing the event.
We fix this by escaping the fields names as it happens already
for the table name.

field='const1' AND field='const2' in some cases
Building multiple equality predicates containing
a constant which is compared as a datetime (with a field)
we should take this fact into account and compare the
constant with another possible constatns as datetimes
as well.
E.g. for the
SELECT ... WHERE a='2001-01-01' AND a='2001-01-01 00:00:00'
we should compare '2001-01-01' with '2001-01-01 00:00:00' as
datetimes but not as strings.

The problem was that the multiple evaluations of a ENCODE or
DECODE function within a single statement caused the random
generator to be reinitialized at each evaluation, even though
the parameters were constants.
The solution is to initialize the random generator only once
if the password (seed) parameter is constant.

This patch fixes three bugs as follows. First, aborting the server while purging
binary logs might generate orphan files due to how the purge operation was
implemented:
(purge routine - sql/log.cc - MYSQL_BIN_LOG::purge_logs)
1 - register the files to be removed in a temporary buffer.
2 - update the log-bin.index.
3 - flush the log-bin.index.
4 - erase the files whose names where register in the temporary buffer
in step 1.
Thus a failure while executing step 4 would generate an orphan file. Second,
a similar issue might happen while creating a new binary as follows:
(create routine - sql/log.cc - MYSQL_BIN_LOG::open)
1 - open the new log-bin.
2 - update the log-bin.index.
Thus a failure while executing step 1 would generate an orphan file.
To fix these issues, we record the files to be purged or created before really
removing or adding them. So if a failure happens such records can be used to
automatically remove dangling files. The new steps might be outlined as follows:
(purge routine - sql/log.cc - MYSQL_BIN_LOG::purge_logs)
1 - register the files to be removed in the log-bin.~rec~ placed in
the data directory.
2 - update the log-bin.index.
3 - flush the log-bin.index.
4 - delete the log-bin.~rec~.
(create routine - sql/log.cc - MYSQL_BIN_LOG::open)
1 - register the file to be created in the log-bin.~rec~
placed in the data directory.
2 - open the new log-bin.
3 - update the log-bin.index.
4 - delete the log-bin.~rec~.
(recovery routine - sql/log.cc - MYSQL_BIN_LOG::open_index_file)
1 - open the log-bin.index.
2 - open the log-bin.~rec~.
3 - for each file in log-bin.~rec~.
3.1 Check if the file is in the log-bin.index and if so ignore it.
3.2 Otherwise, delete it.
The third issue can be described as follows. The purge operation was allowing
to remove a file in use thus leading to the loss of data and possible
inconsistencies between the master and slave. Roughly, the routine was only
taking into account the dump threads and so if a slave was not connect the
file might be delete even though it was in use.
"mysql_upgrade (ver 5.1) add 3 fields to mysql.proc table but does
not set values".
mysql_upgrade (ver 5.1) adds 3 fields (character_set_client,
collation_connection and db_collation) to the mysql.proc table, but
does not set any values. When we run stored procedures, which were
created with mysql 5.0, a warning is logged into the error log.
The solution to this is for mysql_upgrade to set default best guess
values for these fields. A warning is also written during upgrade, to
make the user aware that default values are set.
client/mysql_upgrade.c:
Result lines which start with "WARNING" are passed through to the output.
This way we have a way of triggering WARNING-messages during upgrade
directly from the .sql-script.
mysql-test/r/mysql_upgrade.result:
Expected result of the test.
mysql-test/t/mysql_upgrade.test:
Added a test-case for the bug.
scripts/mysql_system_tables_fix.sql:
The new fields are populated, and warnings are written.
When checking for an error after removing the special view error handler the code
was not taking into account that open_tables() may fail because of the current
statement being killed.
Added a check for thd->killed.
Added a client program to test it.
Problem: Item_char_typecast reported wrong max_length when
casting to BINARY, which lead, in particular, in wrong
"ORDER BY BINARY(char_column)" results.
Fix: making Item_char_typecast report correct max_length.

Problem: SHOW CREATE FUNCTION and SELECT DTD_IDENTIFIER FROM I_S.ROUTINES
returned wrong values in case of ENUM return data type and UCS2
character set.
Fix: the string to collect returned data type was incorrectly set to
"binary" character set, therefore UCS2 values where returned with
extra '\0' characters.
Setting string character set to creation_ctx->get_client_cs()
in sp_find_routine(), and to system_charset_info in sp_create_routine
fixes the problem.
Adding tests:
- the original test with Latin letters
- an extra test with non-Latin letters
Actually there is two different bugs.
The first one caused crash on queries with WHERE condition over views
containing WHERE condition. A wrong check for prepared statement phase led
to items for view fields being allocated in the execution memory and freed
at the end of execution. Thus the optimized WHERE condition refers to
unallocated memory on the second execution and server crashed.
The second one caused by the Item_cond::compile function not saving changes
it made to the item tree. Thus on the next execution changes weren't
reverted and server crashed on dereferencing of unallocated space.
The new helper function called is_stmt_prepare_or_first_stmt_execute
is added to the Query_arena class.
The find_field_in_view function now uses
is_stmt_prepare_or_first_stmt_execute() to check whether
newly created view items should be freed at the end of the query execution.
The Item_cond::compile function now saves changes it makes to item tree.

bug is that the data dictionaries get out of sync. In the AUTOINC code we
try and apply salve to the symptoms. In the past MySQL made some unrelated
change and the dictionaries stopped getting out of sync and this test started
to fail. Now, it seems they have reverted that changed and the test is
passing again. I suspect this is not he last time that this test will change.

------------------------------------------------------------------------
SET TRANSACTION ISOLATION LEVEL is used to temporarily set
the trans.iso.level for the next transaction. After the
transaction, the iso.level is (re-)set to value of the
session variable 'tx_isolation'.
The bug is caused by setting the thd->variables.tx_isolation
field to the value of the session variable upon each
statement commit. It should only be set at the end of the
full transaction.
The fix has been to remove the setting of the variable in
ha_autocommit_or_rollback if we're in a transaction, as it
will be correctly set in either ha_rollback or
ha_commit_one_phase.
If, on the other hand, we're in autocommit mode, tx_isolation
will be explicitly set here.
mysql-test/t/innodb_mysql.test:
"SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED" sets
the trans.isolation for the next transaction. We test
that @@tx_isolation keeps this value during the transaction,
and is only reset back to the session value at the end
of the transaction.

The 'slave_patternload_file' is assigned to the real path of the load data file
when initializing the object of Relay_log_info. But the path of the load data
file is not formatted to real path when executing event from relay log. So the
error will be encountered if the path of the load data file is a symbolic link.
Actually the global 'opt_secure_file_priv' is not formatted to real path when
loading data from file. So the same thing will happen too.
To fix these errors, the path of the load data file should be formatted to
real path when executing event from relay log. And the 'opt_secure_file_priv'
should be formatted to real path when loading data infile.

<tmp_tbl> with RBL
When binlogging the statement, the server always handle the existing
object as a table, even though it is a view. However a view is
handled differently in other parts of the code thus leading the
statement to crash in RBL if the view exists.
This happens because the underlying tables for the view are not opened
when we try to call store_create_info() on the view in order to build
a CREATE TABLE statement.
This patch will only address the crash problem, other binlogging
problems related to CREATE TABLE IF NOT EXISTS LIKE when the existing
object is a view will be solved by BUG 47442.
for each record'
There was an error in an internal structure in the range
optimizer (SEL_ARG). Bad design causes parts of a data
structure not to be initialized when it is in a certain
state. All client code must check that this state is not
present before trying to access the structure's data. Fixed
by
- Checking the state before trying to access data (in
several places, most of which not covered by test case.)
- Copying the keypart id when cloning SEL_ARGs

mysql client displays wrong character-set of server. When a user changes the
charset of a server, mysql client 'status' command displays wrong charset but
the command "SHOW VARIABLES LIKE "%charset%" displayed correct charset results.
The problem is only with the mysql client's 'status' command output.
In mysql client, the method mysql_store_lazy_result() returns 0 for
success and non-zero for failure. The method com_status() was using this method
wrongly. Fixed all such instances according to return value of the method
mysql_store_lazy_result().

In RBR, All statements operating on temporary tables should not be binlogged.
Despite this fact, after executing 'TRUNCATE... ' on a temporary table,
the command is still logged, even if in row-based mode. Consequently, this raises
problems in the slave as the table may not exist, resulting in an
execution failure. Ultimately, this causes the slave to report
an error and abort.
After this patch, 'TRUNCATE ...' statement on a temporary table will not be
binlogged in RBR.
The problem is that the server could crash when attempting
to access a non-conformant proc system table. One such case
was a crash when invoking stored procedure related statements
on a 5.1 server with a proc system table in the 5.0 format.
The solution is to validate the proc system table format
before attempts to access it are made. If the table is not
in the format that the server expects, a message is written
to the error log and the statement that caused the table to
be accessed fails.

Bug #48370 Absolutely wrong calculations with GROUP BY and
decimal fields when using IF
Added the test cases in the above two bugs for regression
testing.
Added additional tests that demonstrate a incomplete fix.
Added a new factory method for Field_new_decimal to
create a field from an (decimal returning) Item.
In the new method made sure that all the precision and
length variables are capped in a proper way.
This is required because Item's can have larger precision
than the decimal fields and thus need to be capped when
creating a field based on an Item type.
Fixed the wrong typecast to Item_decimal.
When merging ranges during calculation of the result of OR
to two range sets the current range may be obsoleted by the
resulting merged range.
The first overlapping range can be obsoleted as well.
Fixed by moving the pointer to the first overlapping range to the
pointer of the resulting union range.
Added few comments at key places in key_or().
Problem: Some system functions that could return different values on
master and slave were not marked unsafe. In particular:
GET_LOCK
IS_FREE_LOCK
IS_USED_LOCK
MASTER_POS_WAIT
RELEASE_LOCK
SLEEP
SYSDATE
VERSION
Fix: Mark these functions unsafe.
mysql-test/extra/rpl_tests/rpl_stm_000001.test:
- The test does not work in mixed mode any more, since it tries to
simulate an error in the sql thread in a query that uses get_lock.
Since get_lock now causes the query to be logged in row format,
the error didn't happen. Hence, we now force statement mode.
- Warnings must be disabled when the unsafe query is issued.
- Replaced some save_master_pos+connection slave+sync_with_master
by sync_slave_with_master.
