I have a ULONGLONG system variable in my storage engine, and I set its value to '-1' on the mysqld command line. Its value gets set to all ones without any warnings or errors. The number conversion functions just cast between longlong and ulonglong types without regard to the sign of the number. Is this correct behavior?

I agree that one can argue that it's not correct. As far as I can see, it should be easy to fix this behavior. On the other hand, I might imagine that people got used to writing --option=-1 to mean "huge value, practically no limit". That is, while it's technically easy to fix, I'm not sure it should be fixed. Regards, Sergei
