- First code. Elimination works for simple cases, passes the testsuite.
- Known issues:
= No elimination is done for aggregate functions.
= EXPLAIN EXTENDED shows eliminated tables (I think it better not)
= No benchmark yet
= The code needs some polishing.

number increases.

Revert earlier wrong change.

Adjust testsuite to copy with new PBXT engine now in the tree. The PBXT engine causes an
extra table to appear in the INFORMATION_SCHEMA. This causes different output for a few
test cases.
dbug/dbug.c:
If DbugParse() is called multiple times, the stack->keywords for the
top stack frame could be overwritten without being freed, causing a
memory leak reported by Valgrind.

storage/archive/azio.c:
Silence Valgrind false warning for libz.
Test was flakey on some machines and showed spurious
reds for races.
New-and-improved test makes do with fewer statements,
no mysqltest-variables, and no backticks. Should hope-
fully be more robust. Heck, it's debatable whether we
should have a test for this, anyway.

due to name_const substitution
Problem:
"In general, statements executed within a stored procedure
are written to the binary log using the same rules that
would apply were the statements to be executed in standalone
fashion. Some special care is taken when logging procedure
statements because statement execution within procedures
is not quite the same as in non-procedure context".
For example, each reference to a local variable in SP's
statements is replaced by NAME_CONST(var_name, var_value).
Queries like
"CREATE TABLE ... SELECT FUNC(local_var ..."
are logged as
"CREATE TABLE ... SELECT FUNC(NAME_CONST("local_var", var_value) ..."
that leads to differrent field names and
might result in "Incorrect column name" if var_value is long enough.
Fix: in 5.x we'll issue a warning in such a case.
In 6.0 we should get rid of NAME_CONST().
Note: this issue and change should be described in the documentation
("Binary Logging of Stored Programs").

Fine-tuning. Broke out comparison into method by

case in 5.1+.
(Pushing for Azundris)
We allow security-contexts with NULL users (for
system-threads and for unauthenticated users).
If a non-SUPER-user tried to KILL such a thread,
we tried to compare the user-fields to see whether
they owned that thread. Comparing against NULL was
not a good idea.
If KILLer does not have SUPER-privilege, we
specifically check whether both KILLer and KILLee
have a non-NULL user before testing for string-
equality. If either is NULL, we reject the KILL.
mysql-test/r/rpl_temporary.result:
Try to have a non-SUPER user KILL a system thread.
mysql-test/t/rpl_temporary.test:
Try to have a non-SUPER user KILL a system thread.

Make sure security contexts of both KILLer *and*
KILLee are non-NULL before testing for string-equality!
The issue happened to be two-fold.
The table map event was recorded into binlog having
an incorrect size when number of columns exceeded 251.
The Row-based event had incorrect recording and restoring m_width member within

LOAD_FILE
LOAD_FILE is not safe to replicate in STATEMENT mode, because it
depends on a file (which is loaded on master and may not exist in
slave(s)). This leads to scenarios on which the slave replicates the
statement with 'load_file' and it will try to load the file from local
file system. Given that the file may not exist in the slave filesystem
the operation will not succeed (probably returning NULL), causing
master and slave(s) to diverge. However, when using MIXED mode
replication, this can be made to work, if the statement including
LOAD_FILE is marked as unsafe, triggering a switch to ROW mode,
meaning that the contents of the file are written to binlog as row
events. Consequently, the contents from the file in the master will
reach the slave via the binlog.
This patch addresses this bug by marking the load_file function as
unsafe. When in mixed mode and when LOAD_FILE is issued, there will be
a switch to row mode. Furthermore, when in statement mode, the
LOAD_FILE will raise a warning that the statement is unsafe in that
mode.
mysql-test/extra/rpl_tests/rpl_loadfile.test:
Extra file that is "sourced" on both rpl_loadfile and rpl_stm_loadfile
test files.
mysql-test/suite/rpl/r/rpl_loadfile.result:

mysql-test/suite/rpl/r/rpl_stm_loadfile.result:
Result file for rpl_loadfile test split with the warnings in statement
mode.
mysql-test/suite/rpl/t/rpl_loadfile.test:
After splitting the original rpl_loadfile file, this one is only
required to be executed in mixed or row format.
Appended the test for 39701 to this file.
mysql-test/suite/rpl/t/rpl_stm_loadfile.test:
Split the original rpl_loadfile test because load_file now raises
a warning when in statement mode. The goal of this split is
two-fold: i) make the test case more resilient; ii) assert that
warnings are indeed raised when in statement mode.
sql/item_create.cc:
Added the set_stmt_unsafe call to lex.
When do 'insert delayed' operation, the time_zone info doesn't be keeped in the row info.
So when we do insert sometime later, time_zone didn't write into binlog.
This will cause wrong result for timestamp column in slave.
Our solution is that adding time_zone info with the delayed-row and
restoring time_zone from row-info when execute that row in the furture by another thread.
So we can write correct time_zone info into binlog and got correct result in slave.
mysql-test/r/rpl_timezone.result:
Test result
mysql-test/t/rpl_timezone.test:
Add test for bug#41719
sql/sql_insert.cc:
