Bug#35220: ALTER TABLE too picky on reserved word "foreign"
In ALTER TABLE, change the internal parser to search for
``FOREIGN[[:space:]]'' instead of only ``FOREIGN'' when parsing
ALTER TABLE ... DROP FOREIGN KEY ...; otherwise it could be mistaken
with ALTER TABLE ... DROP foreign_col;
(This fix is already present in MySQL 5.1 and higher.)

Bug #34286 Assertion failure in thread 2816 in file .\row\row0sel.c line 3500
Since autoinc init performs a MySQL SELECT query to determine the auto-inc
value, set prebuilt->sql_stat_start = TRUE so that it is performed like any
normal SELECT, regardless of the context in which it was invoked.
Bug #35352 If InnoDB crashes with UNDO slots full error the error persists on restart
We've added a heuristic that checks the size of the UNDO slots cache lists
(insert and upate). If either of cached lists has more than 500 entries then we
add any UNDO slots that are freed, to the common free list instead of the cache
list, this is to avoid the case where all the free slots end up in only one of
the lists on startup after a crash.
Tested with test case for 26590 and passes all mysql-test(s).
Bug #36600 SHOW STATUS takes a lot of CPU in buf_get_latched_pages_number
Fixed by removing the Innodb_buffer_pool_pages_latched variable from SHOW
STATUS output in non-UNIV_DEBUG compilation.
min() and max() functions are implemented in MySQL as macros.
This means that max(a,b) is expanded to: ((a) > (b) ? (a) : (b))
Note how 'a' is quoted two times.
Now imagine 'a' is a recursive function call that's several 10s of levels deep.
And the recursive function does max() with a function arg as well to dive into
recursion.
This means that simple function call can take most of the clock time.
Identified and fixed several such calls to max()/min() : including the IF()
sql function implementation.

Problem: binlog_stm_binlog runs INSERT DELAYED queries, and
then prints the contents of the binlog. Before checking the
contents of the binlog, the test waits until the rows have
appeared in the table. However, this is not enough, since
INSERT DELAYED does not write rows to the binlog at the same
time as it writes them to the table. So there is a race.
Fix: Add a FLUSH TABLES before SHOW BINLOG EVENTS. That
waits until the insert_delayed thread is done.
mysql-test/extra/binlog_tests/binlog_insert_delayed.test:
- Added FLUSH TABLES, so that SHOW BINLOG EVENTS becomes
deterministic.
- Added comments.
- Removed unnecessary 'set @@session.auto_increment_increment'
statements.
- Removed unnecessary check that the number of rows inserted
to the table is 11.

Range scan in descending order for c <= <col> <= c type of
ranges was ignoring the DESC flag.
However some engines like InnoDB have the primary key parts
as a suffix for every secondary key.
When such primary key suffix is used for ordering ignoring
the DESC is not valid.
But we generally would like to do this because it's faster.
Fixed by performing only reverse scan if the primary key is used.
Removed some dead code in the process.

Problem: the test waits for a 'DROP TEMPORARY TABLE' event to
appear in the master's binlog, then checks on the slave whether
the number of temporary tables has decreased. The slave does
not sync, causing a race.
Fix: check for the 'DROP TEMPORARY TABLE' event on slave
instead of on master.
mysql-test/suite/rpl/t/rpl_trunc_temp.test:
- Fixed BUG#37493 by waiting for the event on the slave
instead of on the master.
- Added comments.
This is not a fix to the bug. It only adds debug info, so
that we can analyze the bug better next time it happens.
Please revert the patch after the bug is fixed.
mysql-test/suite/rpl/t/rpl_incident.test:
Added debug info. This will only be printed if the
test fails.
the reason for the failure is that io thread passes through a sequence of state
changes before it eventually got stuck at the expect running state as NO.
It's unreasonble to wait for the running status while the whole idea of the test is
to get to the IO thread error.
Fixed with changing the waiting condition.

deploying the exact waiting condition i.e to wait for the slave io error.
Problem: master binlog has 'create table t1'. Master binlog
was removed before slave could replicate it. In test's cleanup
code, master did 'drop table t1', which caused slave sql
thread to stop with an error since slave sql thread did not
know about t1.
Fix: t1 is just an auxiliary construction, only needed on
master. Hence, we turn off binlogging before t1 is created,
drop t1 as soon as we don't need it anymore, and then turn
on binlogging again.

by 'source include/show_binlog_events.inc'.

Many dump threads can exist due to a way the new version of mtr governs suites.

refining the bug#17284 test to avoid counting dump threads in favor to reconnect
explicitly with preserving the orig logics.
Problem: the test set @@global.init_slave to garbage at a time
which was not guaranteed to be after the time when the slave's
SQL thread used it. That would cause the slave's SQL thread to
stop in rare cases.
Fix: The test does not care about the value of
@@global.init_slave, except that it should be different on
master and slave. Hence, we set @@global.init_slave to
something that is valid SQL.
