[Bug: 21.4.20] Network Drives

[Steve Higham]

Vin, Stephen, Benson,

I have been trying to build xemacs on my machine to investigate this bug. I
have been building on Windows using MS VS 2005.

An exception (debug assertion) is being thrown during the build. This is
coming from the Microsoft file access.c line 81 (fn _access_s). The
expression failing is ((amode &(~6)) == 0). This is failing due to an
"amode" value of 1. I have traced this call back to a call into fn
locate_file in xemacs file lread.c with a mode value of 1.

The executable being run at the time was temacs.exe.

The makefile had fired this off with the following command: -

"C:\Temp\XEmacs\xemacs-21.4.20\lib-src\i"
"C:\Temp\XEmacs\xemacs-21.4.20\src\temacs.exe" -batch -l
C:\Temp\XEmacs\xemacs-21.4.20\lisp\make-docfile.el -- -o
C:\Temp\XEmacs\xemacs-21.4.20\lib-src\DOC -i

I would like any help with the following points: -
Is this a known issue - if so how do I workaround it to build xemacs
successfully?
Where are these enumerations for the file access mode coming from?
Is it possible that this issue is also causing the problems I have been
experiencing with networked drives?

Any help really appreciated. This is the first time I have tried to build
xemacs.

Kind Regards,

Steve

Hi Vin,

The shared drive is hosted on a Windows 2000 Pro box.

I have just created a new file (S:\test.txt) on the server. This worked fine
and is editable on the server. However I cannot edit it when connecting over
the network. I can edit it (and save it) over the network using GNU Emacs so
this is not a permissions issue.

According to explorer the attributes are "AC". Both server and network
client have "Full control" permissions.

This problem is affecting all my files on my network drive. Everything was
working fine until I upgraded from previous version (21.4.13).

My network client is running XP Pro 64. This shared drive is accessed by a
number of other applications which are not experiencing this problem.

Please let me know if I can help further.

Kind Regards,

Steve

Thanks for the bug report.  As Stephen mentioned, this is an area that
has been undergoing active work in the last couple of releases.  In
any case, a few more details would help.  Is s: a samba share?  Also,
please send us the permissions on s:\Misc\Todo.txt as well as the
s:\Misc directory.

Thanks,
  Vin
