Is this a ruby bug?

[J. D.]

In the following code, the line marked #bad# only finds '.' and '..'
directories. But the line marked #good# finds all the subdirectories.

I tested this in the same directory, passing the same argument (even so
far as using the UP arrow key to avoid typo differences).

Is this a bug in Ruby 1.8.2 snapshot? Should the two lines produce the
same results?

#ruby

def dirloop(rootdir)


#bad# Dir.foreach(rootdir){|dir|
#good# Dir[rootdir + "/**/*"].each{|dir|

if(FileTest.directory?(dir)) then
puts "found directory #{dir}";
end
}
end

rootDir = ARGV[0];
puts "starting at root directory #{rootDir}";
dirloop(rootDir);

I fixed several bugs in file globing. Try CVS ruby_1_8 branch or
tomorrow's stable snapshot.
