# ==== Purpose ====
#
# Some statements can not be written to the binlog in a safe manner
# with statement-based replication, either because they rely on
# features that are local to the server they are replicated from
# (e.g., @@variables), or because they include nondeterministic
# queries (e.g., LIMIT), or because the time at which the query is
# executed cannot be determined (e.g., INSERT DELAYED).  Such
# statements should be marked unsafe.  All unsafe statements should
# give a warning.
# Yet the warning/error message isn't issued when SQL_LOG_BIN is turned off.
#
# This test verifies that a warning is generated for statements that
# should be unsafe, when they are executed under statement mode
# logging.
#
# All variables should be unsafe, with some exceptions.  Therefore,
# this test also verifies that the exceptions do *not* generare a
# warning.
#
#
# ==== Method ====
#
# We try an INSERT DELAYED statement and verify that a warning is
# issued.
#
# We try to insert unsafe variables into a table in several ways:
# directly with an INSERT statement, from a stored procedure, from a
# stored function, from a trigger, from a prepared statement, and from
# a complicated nesting of triggers, functions, procedures, and
# prepared statements.  In all cases, a warning should be issued.
#
# 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

# ==== Related bugs and worklogs ====
#
# WL#3339: Issue warnings when statement-based replication may fail
# BUG#31168: @@hostname does not replicate
# BUG#34732: mysqlbinlog does not print default values for auto_increment variables
# BUG#34768: nondeterministic INSERT using LIMIT logged in stmt mode if binlog_format=mixed
# BUG#41980, SBL, INSERT .. SELECT .. LIMIT = ERROR, even when @@SQL_LOG_BIN is 0
# BUG#42640: mysqld crashes when unsafe statements are executed (STRICT_TRANS_TABLES mode)
# BUG#47995: Mark user functions as unsafe
# BUG#49222: Mare RAND() unsafe
#
# ==== Related test cases ====
#
# rpl.rpl_variables verifies that variables which cannot be replicated
# safely in statement mode are replicated correctly in mixed or row
# mode.
#
# rpl.rpl_variables_stm tests the small subset of variables that
# actually can be replicated safely in statement mode.
#
#
# ==== Todo ====
#
# There are several other ways to create unsafe statements: see, e.g.,
# WL#3339, BUG#34768.
