# ==== Purpose ====
#
# A few special SQL statements/constructs can generate multiple
# transactions in the binary log.  This poses interesting problems
# especially when it comes to generating and preserving GTIDs.
#
# There are four cases to consider:
#
# - When GTID_MODE=ON/ON_PERMISSIVE and GTID_NEXT=AUTOMATIC, a
#   separate GTID should be generated for each of the statements.
#
# - When GTID_MODE=ON and GTID_NEXT=UUID:NUMBER, an error should be
#   generated since it is impossible to log the statement using just
#   the given GTID.  The exact point when error can be generated
#   (before starting to execute, after executing the first transaction
#   of the statement, or after executing all transactions of the
#   statement) depends on the statement.
#
# - When GTID_MODE=OFF/OFF_PERMISSIVE and GTID_NEXT=AUTOMATIC, an
#   Anonymous_gtid_log_event should be generated for each of the
#   statements.
#
# - When GTID_MODE=OFF and GTID_NEXT=ANONYMOUS, an
#   Anonymous_gtid_log_event should be generated for each of the
#   statements.  Moreover, anonymous ownership should not be released
#   until the last transaction generated by the statement is written
#   to the binary log.
#
# The following statements can generate multiple transactions in the
# binary log:
#
#  1. CALL: when a stored procedure executes multiple statements in
#     autocommit mode, each statement will be logged as a separate
#     transaction.
#
#  2. DROP TABLE: when a single statement drops multiple tables, then
#     there will be a separate statement for all dropped non-temporary
#     tables, a separate statement for all dropped transactional
#     temporary tables, and a separate statement for all dropped
#     non-transactional tables.
#
#  3. DROP DATABASE: this statement will first drop all non-temporary
#     tables in the database, and then try to remove the database
#     directory.  If removing the directory fails (e.g., because there
#     is an unrelated file in the directory), then the statement will
#     be logged as a single DROP TABLE statement listing all tables.
#     If there are many tables, the statement becomes big.  To avoid
#     too big statements, the statement is split into multiple DROP
#     TABLE statements, each with length at most 1024 bytes.
#
#     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.
#
#  4. CREATE TABLE ... SELECT: this statement contains both DDL and
#     DML.  When binlog_format=ROW, all DML must be logged in row
#     format, but at the same time DDL can only be logged in statement
#     format.  Therefore this statement is logged as a CREATE TABLE
#     followed by row events.  This statement is not allowed when
#     GTID_MODE = ON.
#
# This test verifies that all these statements work, for all values of
# GTID_MODE/GTID_NEXT, and both on a client connection and in a slave
# connection.
#
# ==== Implementation ====
#
#  1. CALL. We execute a multi-transaction CALL:
#
#     - On master with GTID_MODE='AUTOMATIC';
#     - On master with GTID_MODE!='AUTOMATIC' ('ANONYMOUS'/'UUID:NUMBER',
#       depending on GTID_MODE)
#     - Not on slave. Since CALL does not get logged as CALL, there is
#       no way to get it in the binary log.
#
#  2. DROP TABLE. We drop all combinations of two or three tables,
#     from the different categories non-temporary, temporary
#     transactional, and temporary non-transactional.  This is done in
#     three ways:
#
#     - On master with GTID_MODE='AUTOMATIC'
#     - On master with GTID_MODE!='AUTOMATIC' ('ANONYMOUS'/'UUID:NUMBER',
#       depending on GTID_MODE)
#     - On slave. This can be done using different table definitions
#       on master and slave. On master we use only non-temporary
#       tables, so that any DROP TABLE statement will succeed and make
#       it to the binary log.  In order to make the tables temporary
#       on slave, we first create the non-temporary table on master,
#       then sync it to slave, then drop it on slave, and then use a
#       stored procedure on master that creates a temporary table with
#       the same name *only* when it executes on the slave.
#
#  3. DROP DATABASE. We try five different error scenarios:
#
#     3.1. Database exists and is empty.
#     3.2. Database exists and contains one table.
#     3.3. Database exists and contains many tables with long names, so
#          that the statement gets split into multiple transactions in
#          the binary log.
#     3.4. Database has not been created, but the directory exists.
#     3.5. Database has not created and the directory does not exist.
#
#     We run these five 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.
#
#     In scenarios 3.1-3.4, we create an extra file in the database
#     directory to trigger the error: to trigger the error on master
#     we create the file in master's database directory; to trigger on
#     slave we create it in slave's database directory. In scenario
#     3.5 we create the directory on master
#
#  4. CREATE TABLE ... SELECT.  This is tested in a different test
#     (rpl_gtid_create_select.test), since the statement cannot be
#     executed if gtid_mode=on.
