vc-bzr failed in Windows XP

[Leo]

Hi There6,

I am running Emacs on Windows XP downloaded from
http://ourcomments.org/Emacs/EmacsW32.html. The version is GNU Emacs
23.0.60.1 (i386-mingw-nt5.1.2600) of 2008-06-29 on LENNART-69DE564.

sha1sum.exe downloaded from
ftp://ftp.gnupg.org/gcrypt/binary/sha1sum.exe.

Now when I try to open a file in bzr repo and type C-x v =, Emacs throws
the following backtrace:

Debugger entered--Lisp error: (args-out-of-range 1 41)
  buffer-substring(1 41)
  (let ((prog sha1-program) (args nil)) (when (consp prog) (setq args ...) (setq prog ...)) (apply (quote process-file) prog (file-relative-name file) t nil args) (buffer-substring (point-min) (+ ... 40)))
  (progn (set-buffer-multibyte nil) (let (... ...) (when ... ... ...) (apply ... prog ... t nil args) (buffer-substring ... ...)))
  (unwind-protect (progn (set-buffer-multibyte nil) (let ... ... ... ...)) (and (buffer-name temp-buffer) (kill-buffer temp-buffer)))
  (save-current-buffer (set-buffer temp-buffer) (unwind-protect (progn ... ...) (and ... ...)))
  (with-current-buffer temp-buffer (unwind-protect (progn ... ...) (and ... ...)))
  (let ((temp-buffer ...)) (with-current-buffer temp-buffer (unwind-protect ... ...)))
  (with-temp-buffer (set-buffer-multibyte nil) (let (... ...) (when ... ... ...) (apply ... prog ... t nil args) (buffer-substring ... ...)))

Try to figure out what the output of "sha1sum" is -- my guess is it's
not producing any output at all, or just an error.  It looks to me like
the lisp code is merely assuming that the output contains a 41-byte
hexencoded SHA1 sum, which will be the case only if the program is
actually working properly.

In DOS window, sha1sum FILE produces a correct output
(e.g. ae7734e7a54353ab13ecba780ed62344332fbc6f putty.exe).

However in the mentioned elisp, the temp buffer contains only:

,----
| usage: sha1sum filenames
`----

Looks like a bug in that elisp code.

Hi leo

Because the elisp call sha1sum use stdin not filename.
elisp:
    sha1sum < you_file_path
But your sha1sum.exe only support:
    sha1sum you_file_path

??? What version of sha1sum do you have installed?  The one I have,
from Coreutils 5.3.0, does read stdin by default.
