Bug Description
Description:
Error log gets filled with spam like this:
[Warning] Client failed to provide its character set. 'latin1' will be used as client character set.
[Warning] Client failed to provide its character set. 'latin1' will be used as client character set.
How to repeat:
- HAProxy's mysql-check option causes this warning as well. A solution for suppressing this warning would be helpful to keep error logs clean.
- Simplest example, login to server with an 4.0.forever client.
I tried to disable the warnings from my.cnf using log-warnings=0 and log_warnings_
Distro: Ubuntu Precise (12.04.4)
