# ==== Purpose ====
|
|
#
|
|
# Verify that Bug#22110284 has been fixed, i.e. that replication from a smaller
|
|
# type to a larger type performs the correct conversion and does not truncate
|
|
# the columns on the slave.
|
|
#
|
|
# ==== Implementation ====
|
|
#
|
|
# 1. Set @@global.SLAVE_TYPE_CONVERSIONS to ALL_NON_LOSSY to allow conversions.
|
|
# 2. Create a table on the master, wait until it has been replicated, drop table
|
|
# on slave and recreate with a column with greater size.
|
|
# 3. Insert values that would have be truncated on the master and wait for
|
|
# them to be replicated.
|
|
# 4. Verify that the columns have the same length on the master and slave.
|
|
