[Message part 1 (text/plain, inline)]

In eshell, running the command "ls -al" can produce the following error:

 

c:/Derek $ ls -al

total 593

Wrong type argument: integerp, -2023488832.0

 

From correspondence with Eli Zaretskii on the help-emacs-windows mailing

list, this is due to the fact that a user's uid can be a float larger
than

an Emacs Lisp integer can hold.

 

The owner of the .. directory (c: itself) appears to be a user called

TrustedInstaller.

Thank you for your report.  Could you please post the full SID
(Security Identifier) of this TrustedInstaller user?  This user is new
with Vista, so I'd like to have its SID value to better understand
what it does to Emacs code (for example, why the numeric UID comes out
negative, as your report shows).

There are several utilities available to display the SID.  One of them
is `subinacl', which can be downloaded from here:

  http://www.microsoft.com/downloads/details.aspx?FamilyID=e8ba3e56-d8fe-4a91-93cf-ed6985e3927b&displaylang=en

After you install it, the following command line will display the SID
of the owner of the root directory of the C: drive:

  subinacl /file C:\ /display=sddl

Please post here the full output of that command.

From info on the Internet, I understand that Vista comes with a
similar utility called icacls.exe, but I don't have a Vista where I'm
typing this, so I could not verify whether it can display the SID of
the owner, and what switches would you need to give it for that.

Thanks.

Hi Eli,

I have moved this to a non-work email to avoid the signature that accompanied my other emails. Sorry if that caused an inconvenience.

Here is the output from the subinacl command that you asked for:

C:\>subinacl /file C:\ /display=sddl

Thanks, this gives me what I need to fix the problem.

Fixed with the two changes below.

Still todo: make uid_t and gid_t unsigned types on Windows, to avoid
negative values for users such as TrustedInstaller, with a suitable
change in the emulated `struct stat'.

2009-03-18  Eli Zaretskii  <eliz <at> gnu.org>

	* dired.c (Ffile_attributes): Make sure UID and GID are always
	positive, even if the value is too large for a positive EMACS_INT.
	Doc fix.

	* editfns.c (Fuser_login_name): Support float arguments.  Doc fix.
