Subject: [ruby-talk:15738] Ruby globbing problem?


I have two directories, one being a "real" directory, the other one being
a symlink to another directory. It seems that Ruby will have some problems
globbing with Dir#[] when a symlink is in the way, while Dir#entries and
Dir#open/each seem to work.. quite strange.


        In irb:

irb(main):001:0> Dir.entries("/mnt").size
7
irb(main):002:0> Dir.entries("/SRPMS").size
1117
irb(main):003:0> Dir["/mnt/*"]
["/mnt/cdrom", "/mnt/nfs", "/mnt/disk", "/mnt/floppy", "/mnt/distrib"]
irb(main):004:0> Dir["/SRPMS/*"]
[]
irb(main):005:0> a=0 ; Dir.open("/SRPMS").each { print "\r#{a+=1}" }
1117#<Dir:0x401bf2d4>


        Globbing from the shell:

[gc@obiwan ~] ls -d /mnt/* | wc -l
      5
[gc@obiwan ~] ls -d /SRPMS/* | wc -l
   1115


        Globbing from the glibc:

[gc@obiwan ~/tmp] cat > t.c 
#include <stdio.h>
#include <glob.h>
int main() {
	glob_t g;
	glob("/SRPMS/*", 0, NULL, &g);
	printf("matches: #%d\n", g.gl_pathc);
}
[gc@obiwan ~/tmp] gcc t.c
[gc@obiwan ~/tmp] ./a.out 
matches: #1115



[gc@obiwan ~] ruby -v
ruby 1.6.3 (2001-03-22) [i586-linux-gnu]


Best,
