# This test works as expected, it's a negative test.
# The message "[ERROR] Failed to write to mysql.general_log"
# is printed to master.err when writing to the table mysql.general_log
# failed.
# However, this message is picked up by mysql-test-run.pl,
# and reported as a test failure, which is a false negative.
# There is no current way to *selectively* filter out these expected error conditions
# (see mysql-test/lib/mtr_report.pl, mtr_report_stats()).
# Instead of filtering all occurences of "Failed to write to
# mysql.general_log", which could hide bugs when the error is not expected,
# this test case is commented instead.

# mysql-test-run.pl (based on the test name ?), and uncomment this test.
