STATUS'
NOTE: this is the backport to next-mr.
SHOW SHOW STATUS LIKE 'Slave_running' command believes that
if active_mi->slave_running != 0, then io thread is running normally.
But it isn't so in fact. When some errors happen to make io thread
try to reconnect master, then it will become transitional status
(MYSQL_SLAVE_RUN_NOT_CONNECT == 1), which also doesn't equal 0.
Yet, "SHOW SLAVE STATUS" believes that only if
active_mi->slave_running == MYSQL_SLAVE_RUN_CONNECT, then io thread is running.
So "SHOW SLAVE STATUS" can get the correct result.
Fixed to make SHOW SHOW STATUS LIKE 'Slave_running' command have the same
check condition with "SHOW SLAVE STATUS". It only believe that the io thread
is running when active_mi->slave_running == MYSQL_SLAVE_RUN_CONNECT.
This patch adds functionality to row-based replication to ensure the
slave's column sizes are >= to that of the master.
It also includes some refactoring for the code from WL#3228.
mysql-test/extra/rpl_tests/rpl_extraSlave_Col.test:
BUG#22086 : Extra Slave Col: Char(5) on slave and Char(10) on master cause mysqld crash
Removed commented out portion of test referenced in bug report. This
test supports the original request of the bug report.

BUG#22086 : Extra Slave Col: Char(5) on slave and Char(10) on master cause mysqld crash
New result file for additional test.

New result file for additional test.
sql/field.cc:
BUG#22086 : Extra Slave Col: Char(5) on slave and Char(10) on master cause mysqld crash
This patch refactors the additions made by this bug patch and those
made by WL#3228. The effort consolidates the large switches on type()
into functions within the field classes.
sql/field.h:
BUG#22086 : Extra Slave Col: Char(5) on slave and Char(10) on master cause mysqld crash
This patch refactors the additions made by this bug patch and those

into functions within the field classes.
sql/log_event.cc:
BUG#22086 : Extra Slave Col: Char(5) on slave and Char(10) on master cause mysqld crash
This patch refactors the calc_field_size() method to use the new
methods implemented in the field classes. It also corrects comments
concerning how replication of field metadata works.
sql/log_event.h:
BUG#22086 : Extra Slave Col: Char(5) on slave and Char(10) on master cause mysqld crash
This patch refactors out the calc_field_size() method into the method
save_field_metadata().
sql/rpl_utility.cc:
BUG#22086 : Extra Slave Col: Char(5) on slave and Char(10) on master cause mysqld crash
This patch adds a method to check the size of the field on the master
using the field metadata from WL#3228. Each column is checked to ensure
the slave's column is >= to the master's column in size.
sql/rpl_utility.h:
BUG#22086 : Extra Slave Col: Char(5) on slave and Char(10) on master cause mysqld crash
This patch changes the table_def class so that it records the size of
the metadata. This is a result of refactoring out the calc_field_size()
method into the method save_field_metadata(). Prevents access via
field_metadata(col) to unitialized memory when there is no metadata
transmitted from the master.
mysql-test/suite/rpl/r/rpl_row_colSize.result:
BUG#22086 : Extra Slave Col: Char(5) on slave and Char(10) on master cause mysqld crash
New result file for additional test.
mysql-test/suite/rpl/t/rpl_row_colSize.test:
BUG#22086 : Extra Slave Col: Char(5) on slave and Char(10) on master cause mysqld crash
Added a test file to test each variable type that relies on field
metadata from the master.
mysql-test/include/test_fieldsize.inc:
BUG#22086 : Extra Slave Col: Char(5) on slave and Char(10) on master cause mysqld crash
Sub unit file to test each variable type that relies on field
metadata from the master.
