# ==== Purpose ====
#
# Test that temporary tables are correctly replicated after switching to ROW format in MIX mode.
# This test case will test the condition of the bug#40013.
# The test step is:
#   1: create temp table on connection 'master';
#   2: switch to ROW format using 'INSERT INTO t1 VALUES (UUID());'
#   3: disconnect 'master' and connect to a new connection 'master1';
#   4: sync to slave and check the number of temp tables on slave.

#
# BUG#43046: mixed mode switch to row format with temp table lead to wrong
# result
#
# NOTES
# =====
#  
#  1. Temporary tables cannot be logged using the row-based
#     format. Thus, once row-based logging is used, all subsequent
#     statements using that table are unsafe, and we approximate this
#     condition by treating all statements made by that client as
#     unsafe until the client no longer holds any temporary tables.
#
#  2. Two different connections can use the same temporary table
#     name without conflicting with each other or with an
#     existing non-TEMPORARY table of the same name.
#
# DESCRIPTION
# ===========
#  
#   The test is implemented as follows:
#     1. create regular tables 
#     2. create a temporary table t1_tmp: should be logged as statement
#     3. issue an alter table: should be logged as statement
#     4. issue statement that forces switch to RBR
#     5. create another temporary table t2_tmp: should not be logged
#     6. issue alter table on t1_tmp: should not be logged
#     7. drop t1_tmp and regular table on same statement: should log both in
#        statement format (but different statements)
#     8. issue deterministic insert: logged as row (because t2_tmp still
#        exists).
#     9. drop t2_tmp and issue deterministic statement: should log drop and
#        query in statement format (show switch back to STATEMENT format)
#    10. in the end the slave should not have open temp tables.
#
