[pmwiki-devel] wrong path in mkdirp message

[Guillermo Calderon - INCO]

When I try to upload a file without giving approppriate permissions 
the following messsage is written to the browser:

----begin-----
PmWiki can't process your request

PmWiki needs to have a writable uploads/ directory before it can 
continue. You can create the directory manually by executing the 
following commands on your server:

     mkdir /uploads
     chmod 777 /uploads

Then, reload this page.

Or, for a slightly more secure installation, try executing

     chmod 2777

on your server and following this link. Afterwards you can restore the 
permissions to their current setting by executing

     chmod 0

.

We are sorry for any inconvenience.
-------end--------

As you can see, all chmod have the wrong paths.
I think the procedure "mkdirp" don't know how to process relative 
paths. In particular, the statement

     $parent = realpath(dirname($dir));

assign the null string to $parent, when $dir is of the form "uploads" 
(a relative path)
