Subject: bug#4673: 23.1; UNC paths of the form "//DFSROOT/SHARE"
Date: Thu, 8 Oct 2009 14:43:21 +0100 [thread overview]
Message-ID: <afe5197f0910080643k5291fa2bm6e7d07f5ac8fcc68@mail.gmail.com> (raw)
On Windows in a domain environment, suppose "//DFSROOT" is a
domain-hosted DFS root, with a share "//DFSROOT/SHARE". (Typically,
DFSROOT will be the name of the domain.)
Interactively, using "C-x C-f / / D F S R O O T / S H A R E RET"
causes an error: "completion--some: Opening directory: invalid
argument, //DFSROOT/". This occurs in Emacs 23.1 but not in Emacs
22.3. I haven't looked into the completion code to see why. This is a
bug.
Note: The list returned by the form (directory-files-and-attributes
"//DFSROOT/SHARE") contains the list ("..") as an element. Evaluating
(directory-files-and-attributes "//DFSROOT") signals an error "Opening
directory: invalid argument, //DFSROOT". This occurs on Emacs 22.3 as
well as Emacs 23.1 and is probably the correct behaviour.
Therefore, in Emacs 23.1 but not in Emacs 22.3, when visiting the
directory "//DFSROOT/SHARE" by evaluating (find-file
"//DFS-ROOT/SHARE"), the function `ls-lisp-insert-directory' fails,
because it does not account for the possibility that an entry in the
list returned by `directory-files-and-attributes' may be missing the
attribute data. The error signalled is "Format specifier doesn't match
argument type", arising from the form (format "%d" fuid) where fuid is
nil. This is a bug. To reproduce, run Emacs 23.1 in a domain
environment where domain-hosted DFS is in use, and visit a directory
of the form "//DOMAIN/SHARE" or "//DFSROOT/SHARE" by evaluating the
expression (find-file "//DFSROOT/SHARE").
Note that the more familiar UNC paths of the form "//SERVER/SHARE",
where SERVER is the name of a computer, will not cause these errors.
