# ==== Purpose ====
#
# This is part of rpl_split_statements.test which covers DROP DATABASE
# statement and one scenario for DROP TABLES statement.
#
# ==============================================================================
#
# DROP TABLES: See detailed description of its behavior in
# rpl_split_statements.test file.
#
# This file contains coverage for the following scenario:
#
#   We drop group of 4 tables, where 2 tables are in SE which
#   do not support atomic DDL and 2 in SE which support it and
#   then fail. This triggers code path in DROP TABLE implementation
#   which differs from case when there is no failure.
#   This is done for both GTID_MODE='AUTOMATIC' and GTID_MODE='UUID:NUMBER'
#   to see difference in splitting/combining. Notice that with GTID
#   assigned even such failed DROP TABLE will consume GTID.
#
# ==============================================================================
#
# DROP DATABASE: this statement will first drop all non-temporary
# tables in the database, then stored routines and events in it,
# and then try to remove database from the data-dictionary.
# If there is an error during one of the latter steps, then the
# removal of events, stored routines and tables in SEs supporting
# atomic DDL will be rolled back. Removal of tables in SEs which
# don't support atomic DDL can't be rolled back and will be logged
# as a group of DROP TABLE IF EXISTS statements, with one DROP
# statement per table.
#
# If GTID_NEXT='UUID:NUMBER', the statement will not be logged and
# the gtid will not be added to GTID_EXECUTED, if the statement
# fails. This is regardless of whether it would result in multiple
# DROP statements or just one.
#
# This test verifies that all DROP DATABASE works, for all values of
# GTID_MODE/GTID_NEXT, and both on a client connection and in a slave
# connection.
#
# === Implementation ===
#
# We try five different error scenarios:
#
#   3.1. Database exists and is empty.
#   3.2. Database exists and contains one InnoDB table
#        (no side-effects of failure).
#   3.3. Database exists and contains one InnoDB and one MyISAM table,
#        so we get single DROP TABLE statement in the binary log.
#   3.4. Database exists and contains one InnoDB and two MyISAM tables,
#        so we get two DROP TABLE statements in the binary log.
#   3.5. Database has not been created, but the directory exists.
#   3.6. Database has not created and the directory does not exist.
#
#   We run these six scenarios in three ways:
#
#   - On master with GTID_MODE='AUTOMATIC'
#   - On master with GTID_MODE!='AUTOMATIC' ('ANONYMOUS'/'UUID:NUMBER',
#     depending on GTID_MODE).
#   - On slave.
#
# We also run scenario with successful drop of database which contains one
# InnoDB and one MyISAM table. In AUTOMATIC/ANONYMOUS mode such statement
# is split into DROP TABLE IF EXISTS for MyISAM table and DROP DATABASE
# statement. With GTID assigned it is logged as single DROP DATABASE
# statement.
#
# This last scenario and scenario 3.6 also provide coverage for changes to
# DROP DATABASE binary logging which were implemented as part of WL#7743
# "New data dictionary: changes to DDL-related parts of SE API".
#

# We use DBUG_EXECUTE_IF to simulate errors during DROP DATABASE.
