MDEV-15919 lower_case_table_names does not behave as expected(nor...
consistently) on Replication Slave lower_case_table_names 0 -> 1 replication works, it's safe as long as mixed case names mapping to the lower case ones is one-to-one

# BUG#37656
|
||||
#
|
||||
# This test aims at checking whether lower_case_table_names=1 option works
|
||||
# for database names and table names.
|
||||
#
|
||||
# This test checks the following (when lower_case_table_names=1 is set on slave):
|
||||
# (i) creating a database on upper case on master results in lower case
|
||||
# database name on slave
|
||||
# (ii) creating tables with upper case names on master results in lower case
|
||||
# table names on slave
|
||||
# (iii) loading data infile into capitalized table name on master replicates to
|
||||
# lower case table name on slave
|
||||
# (iv) Propagating changes from upper case table names on into correspondent
|
||||
# lower case table names on slave works.

# This test case is tests whether replication works properly when

#
|

# (i) master contains capitalized table name
|
||||
#
|
||||
# (ii) slave contains lowered case table name
|
||||
#
|

# (iii) master and slave tables do not differ
