# ==== Background ====
#
# Some statements may execute differently on master and slave when
# logged in statement format.  Such statements are called unsafe.
# Unsafe statements include:
#
#  - statements using @@variables (with a small number of exceptions;
#    see below);
#  - statements using certain functions, e.g., UUID();
#  - statements using LIMIT;
#  - INSERT DELAYED;
#  - insert into two autoinc columns;
#  - statements using UDF's.
#  - statements reading from log tables in the mysql database.
#  - INSERT ... SELECT ... ON DUPLICATE KEY UPDATE
#  - REPLACE ... SELECT
#  - CREATE TABLE [IGNORE/REPLACE] SELECT
#  - INSERT IGNORE...SELECT
#  - UPDATE IGNORE
#  - INSERT... ON DUPLICATE KEY UPDATE on a table with two UNIQUE KEYS
#
# Note that statements that use stored functions, stored procedures,
# triggers, views, or prepared statements that invoke unsafe
# statements shall also be unsafe.
#
# Unsafeness of a statement shall have the following consequences:
#
# 1. If the binlogging is on and the unsafe statement is logged:
#    - If binlog_format=STATEMENT, the statement shall give a warning.
#    - If binlog_format=MIXED or binlog_format=ROW, the statement shall
#      be logged in row format.
#
# 2. If binlogging is off or the statement is not logged (e.g. SELECT
#    UUID()), no warning shall be issued and the statement shall not
#    be logged.
#
# Moreover, when a sub-statement of a recursive construct (i.e.,
# stored function, stored procedure, trigger, view, or prepared
# statement) is unsafe and binlog_format=STATEMENT, then a warning
# shall be issued for every recursive construct.  In effect, this
# creates a stack trace from the top-level statement to the unsafe
# statement.
#
#
# ==== Purpose ====
#
# This test verifies that a warning is generated when it should,
# according to the rules above.
#
# All @@variables should be unsafe, with some exceptions.  Therefore,
# this test also verifies that the exceptions do *not* generate a
# warning.
#
#
# ==== Method ====
#
# 1. Each type of statements listed above is executed.
#
# 2. Each unsafe statement is wrapped in each type of recursive
#    construct (stored function, stored procedure, trigger, view, or
#    prepared statement).
#
# 3. Each unsafe statement is wrapped in two levels of recursive
#    constructs (function invoking trigger invoking UUID(), etc).
#
# We try to insert the variables that should not be unsafe into a
# table, and verify that *no* warning is issued.
#
# Execute a unsafe statement calling a trigger or stored function
# or neither when SQL_LOG_BIN is turned ON, a warning/error should be issued
# Execute a unsafe statement calling a trigger or stored function
# or neither when @@SQL_LOG_BIN is turned OFF,
# no warning/error is issued
