Description Kostas Georgiou 2007-04-16 22:39:11 UTC
Etc.getgrgid returns root always!

$ irb
irb(main):001:0> require 'etc'
=> true
irb(main):002:0> Etc.getgrgid(37)
=> #<struct Struct::Group name="root", passwd="x", gid=0, mem=["root"]>

$ rpm -q ruby
ruby-1.8.5.35-2.fc6

Comment 1 Kostas Georgiou 2007-04-17 00:07:58 UTC
Looking at the code it is obvious why it doesn't work.

static VALUE
etc_getgrgid(obj, id)
    VALUE obj, id;
{
#ifdef HAVE_GETGRENT
    gid_t gid;
    struct group *grp;

    rb_secure(4);
    gid = getgid();
    grp = getgrgid(gid);
    if (grp == 0) rb_raise(rb_eArgError, "can't find group for %d", gid);
    return setup_group(grp);
#else
    return Qnil;
#endif
}

The attached patch, which reverts Etc::getgrgid to what's in both the 1.8.5 and
1.8.6 branches (no idea what happened with p35), seems to work .. at least on
i386 .. at least with the very simple test of
  
  ruby -retc -e 'p Etc::getgrgid(1)'
  #<struct Struct::Group name="bin", passwd="x", gid=1, mem=["root", "bin",
"daemon"]>
