# func_rollback.test
#
# Test variations inspired by
# Bug#12713 Error in a stored function called from a SELECT doesn't cause
# ROLLBACK of statement
# Essential of the bug:
# - A SELECT using a FUNCTION processes a table.
# - The SELECT affects more than row.
# - The FUNCTION modifies a table.
# - When processing the non first matching row, the function fails.
# But the modification caused by the function when the SELECT processed the
# first matching row is not reverted.
#
# Goal of this test: Attempts to catch a situation where
# - a statement A involving the execution of one or more functions is run
# - the function/functions themself contain one or more statements
# modifying a table
# - one of the modifying statements within one of the functions fails
# - the table remains at least partially modified
#
# = There is no automatic ROLLBACK of changes caused by the failing
# statement A.
# = Statement A is not atomic.
#
# Notes:
# - The table to be modified must use a transactional storage engine.
# For example MyISAM cannot avoid the situation above.
# - Some comments assume that the rows of the table t1_select are processed
# in the order of insertion. That means
# SELECT f1,f2 FROM t1_select
# should have the same result set and row order like
# SELECT f1,f2 FROM t1_select ORDER BY f1;
# - The manual says that we get in non strict sql mode a warning around INSERT:
# Inserting NULL into a column that has been declared NOT NULL.
# For multiple-row INSERT statements or INSERT INTO ... SELECT statements,
# the column is set to the implicit default value for the column data type.
