Before this fix, the test performance_schema.relaylog would fail with sporadic failures related to statistics on update_cond. The reason for these failures is that thread scheduling makes impossible to predict if instrumented conditions will be used on not. The fix is to relax the test case, to not collect statistics about: - wait/synch/cond/sql/MYSQL_BIN_LOG::update_cond - wait/synch/cond/sql/MYSQL_RELAY_LOG::update_cond

# Notes
|
|
#
|
|
# The point of this test is to make sure code is properly instrumented,
|
|
# where instruments have the proper key (binlog or relaylog),
|
|
# it is not to dive into statistics for each instruments.
|
|
# Different test execution sequence in different platforms do make the
|
|
# results vary, making the test results very sensitive to changes.
|
|
# To ensure robustness:
|
|
# - log file rotation is limited to file .000001 and .000002
|
|
# - statistics are normalized to "NONE" or "MANY"
|
|
# - statistics on ::update_cond conditions are not collected,
|
|
# since this is too much dependent on execution.
