[ID 20010111.021] (builtin)mkdir and File::Path::mkpath problem
Message ID:

This is a bug report for perl from miki@dds.nl,
generated with the help of perlbug 1.28 running under perl v5.6.0.


-----------------------------------------------------------------
[Please enter your report here]
There seems to be a problem with the built-in function 'mkdir',
as well as (by consequence) library functions that use it (verified
with File::Path::mkpath.
The problem is that the Perl built-in 'mkdir' does not do the right thing
(compared to the *nix 'mkdir') when there is a trailing slash
in the path name.
I noticed the problem when trying to use the HTML::Latex module.

Example (mkdir):

mkdir "foo"; # works, returns true
mkdir "bar/"; # doesn't work and returns false

Example (mkpath):
mkpath("foo/bar/baz"); # works
mkpath("baz/bar/foo/"); # doesn't work, croaks when trying to create 'foo'

A workaround seems to be to apply the following patch:

*** ../Path.pm.orig	Wed Oct 11 02:26:47 2000
--- ../Path.pm	Fri Jan 12 04:43:16 2001

      my(@created,$path);
      foreach $path (@$paths) {
  	$path .= '/' if $^O eq 'os2' and $path =~ /^\w:\z/s; # feature of CRT 
+         $path = File::Spec->canonpath($path);
  	next if -d $path;
  	# Logic wants Unix paths, so go with the flow.
  	$path = VMS::Filespec::unixify($path) if $Is_VMS;
