Interesting points. To be fair, the original implementation only sets the name attribute equal to $_[0] as well, by virtue of $self->{name} = shift. I was less interested in the case of empty array as I was in the case of setting the attribute 'name' to be a scalar value, which seemed to make more sense. Should have been more clear. ;-)

As to die "No arguments in set_name()" unless @_;, note that I did leave a space in the setter to validate behavior, since we aren't going from a spec. Depending on the behavior required, that line may or may not be appropriate. The behavior you described as erratic is what I intended, but its interesting that we looked at the same OP and drew differing conclusions.

I guess this is an example to designers about how unclear specs can lead to unexpected behavior. ;-)

[oiskuu]: Hm. that depends on kernel compiled with CONFIG_AUDITSYSCAL L
[tye]: apropos my several mentions of audit
[Corion]: At least my (non-SELinux) Debian has that config thing set. I don't have non-Debian machines handy (except Android)
[Corion]: My Android phone also has /proc/self/ loginuid, but that displays -1 (resp. 4GB). That might be because the phone is rooted.
[tye]: -1 means nobody logged in or the process was started before audit got booted
[davido]: ok, on my ubuntu system getlogin grabs from /proc/self/ loginuid (per strace)
