Hi everyone
I've installing policyd-weight on Mac OS X 10.4 and discovered
problem. Here is debug:
policyd-weight version: 0.1.14 beta, CacheVer: 3
System: Darwin pagraphics 8.8.0 Darwin Kernel Version 8.8.0: Fri Sep 8

I've found solution here:
http://groups.google.com/group/comp.lang.perl.misc/browse_thread/thread/9beeaa638ba83213/dba793905626ca75%23dba793905626ca75
And have made a dirty hack to make script working - see below (also attached)
871,873c871,878
$( = $gname; if($!) { die ($)($) set GID to
$gname: $!; }
$) = $gname $gname; if($!) { die set EGID to $gname: $!; }
Unfortunately that is not portable either, also, this does not empty the groups
you are in.
Please try following:
perl -wle '
($(,$)) = (80, 80 80); die $! if $!;
($,$) = (80, 80); die $! if $!;
print ruid: $\neuid: $\nrgid: $(\negid: $)\n '
This must output following:
ruid: 80
euid: 80
rgid: 80 80
egid: 80 80
I do NOT expect that to be portable, after all, set*id - regardless which
approach one uses, is non portable, even using use POSIX is non portable.
However, I'll first use the above version, check for errors and then use the
current approach. If nothing works, then the OS/perl on that plattform is
highly broken.
The patch your provided may work on Mac, but outputs here:
linux redhat 7.1, kernel 2.4.25, perl 5.6:
root# perl -wle '
$(=$) = 80; die $! if $!;
$=$ = 80; die $! if $!;
print ruid: $\neuid: $\nrgid: $(\negid: $)\n '
ruid: 80
euid: 80
rgid: 80 10 6 4 3 2 1 0
egid: 80 10 6 4 3 2 1 0
^^ Danger!
FreeBSD 6.1, perl 5.8.8:
root# perl -wle '
quote $(=$) = 80; die $! if $!;
quote $=$ = 80; die $! if $!;
quote print ruid: $\neuid: $\nrgid: $(\negid: $)\n '
