Idea for the fix:

Example configuration files:

Hello Matthew,

Thanks for reporting this bug.

It is validated as a Bug.

Have tested the same way with --ignore-case and pt-config-diff does not honour this option.

pt-config-diff /root/sandboxes/single_mysql_57/my.sandbox.cnf h=127.0.0.1,P=5725 --user=msandbox --password=XXXXXXX --ignore-case

1 config difference

Variable                  /root/sandboxes/single_mysql_57/my.sandbox.cnf local

========================= ============================================== =====

enforce_gtid_consistency  on                                             ON

Thanks,

Sunil
