Subject: 24.5; shell-quote-argument in Emacs 24.5 and Emacs 25 on Windows cannot figure out path correctly
--text follows this line--


Dear Emacs developers/maintainers,

I am writing this email to report an issue that has been bothering me
for a while.

I use python mode (python.el) for some python programming. When I invoke
the command python-shell-send-buffer, my Emacs always reports "Searching
for program: no such file or directory,
c\:/Anaconda3/Scripts/ipython.exe".

I traced down the cause of this problem, and found the following lines
in python.el:
(defun python-shell-parse-command ()    ;FIXME: why name it "parse"?
  "Calculate the string used to execute the inferior Python process."
  ;; FIXME: process-environment doesn't seem to be used anywhere within
  ;; this let.
  (let ((process-environment (python-shell-calculate-process-environment))
        (exec-path (python-shell-calculate-exec-path)))
    (format "%s %s"
            ;; FIXME: Why executable-find?
            (shell-quote-argument (executable-find python-shell-interpreter))
            python-shell-interpreter-args)))

The function call
(shell-quote-argument (executable-find python-shell-interpreter))
changed the path of my python interpreter from
"c:/Anaconda3/Scripts/ipython.exe"
to
"c\\:/Anaconda3/Scripts/ipython.exe".

I worked around this problem by replacing the function call
(shell-quote-argument (executable-find python-shell-interpreter))
with
(executable-find python-shell-interpreter) ;; edited by DZ on
2015/06/05: (shell-quote-argument) caused the problem of
"c\\:/Anaconda3/Scripts/ipython.exe"

To further analyze the problem, I found the function
shell-quote-argument defined in subr.el does not deal with the case when
bash from cygwin is used.

(defun shell-quote-argument (argument)
  "Quote ARGUMENT for passing as argument to an inferior shell."
  (cond
   ((and (eq system-type 'windows-nt) (w32-shell-dos-semantics))
    ;; First, quote argument so that CommandLineToArgvW will
    ;; understand it.  See
    ;; http://msdn.microsoft.com/en-us/library/17w5ykft%28v=vs.85%29.aspx
    ;; After we perform that level of quoting, escape shell
    ;; metacharacters so that cmd won't mangle our argument.  If the
    ;; argument contains no double quote characters, we can just
    ;; surround it with double quotes.  Otherwise, we need to prefix
    ;; each shell metacharacter with a caret.

    (setq argument
          ;; escape backslashes at end of string
          (replace-regexp-in-string
           "\\(\\\\*\\)$"
           "\\1\\1"
           ;; escape backslashes and quotes in string body
           (replace-regexp-in-string
            "\\(\\\\*\\)\""
            "\\1\\1\\\\\""
            argument)))

    (if (string-match "[%!\"]" argument)
        (concat
         "^\""
         (replace-regexp-in-string
          "\\([%!()\"<>&|^]\\)"
          "^\\1"
          argument)
         "^\"")
      (concat "\"" argument "\"")))
   (t
    (if (equal argument "")
        "''"
      ;; Quote everything except POSIX filename characters.
      ;; This should be safe enough even for really weird shells.
      (replace-regexp-in-string
       "\n" "'\n'"
       (replace-regexp-in-string "[^-0-9a-zA-Z_./\n]" "\\\\\\&" argument))))
   ))

I added the following lines in the cond statement, to solve the problem.
   ((and (eq system-type 'windows-nt) (if (string-match ".*cygwin.*" (w32-shell-name)) t nil)) ;; DZ's edit on 6/5/2015
    (if (equal argument "")
        "''"
      ;; Quote everything except POSIX filename characters.
      ;; This should be safe enough even for really weird shells.
      (replace-regexp-in-string
       "\n" "'\n'"
       (replace-regexp-in-string "[^-0-9a-zA-Z_./\n:]" "\\\\\\&" argument))))
   ((eq system-type 'ms-dos)
    ;; Quote using double quotes, but escape any existing quotes in
    ;; the argument with backslashes.
    (let ((result "")
          (start 0)
          end)
      (if (or (null (string-match "[^\"]" argument))
              (< (match-end 0) (length argument)))
          (while (string-match "[\"]" argument start)
            (setq end (match-beginning 0)
                  result (concat result (substring argument start end)
                                 "\\" (substring argument end (1+ end)))
                  start (1+ end))))
      (concat "\"" result (substring argument start) "\"")))

However, the edits does not change the behavior of subr.el.

I worked with Eli Zaretskii on similar problem before, and here I report a more thorough analysis in the hope some experts more capable than me could help to solve this problem.

Thanks.

Da Zhang

Thanks for looking into this again. The change I made is a very ugly hack, and I did not use it actually -- instead, I just changed the python.el to avoid using shell-quote-argument.
For work reason I have to use Windows, but I do use cygwin bash as my working shell and it's convenient to have emacs and bash together, such as in dired, grep, etc.
I understand using cmd.exe could solve the problem, but I am reporting this issue in subr.el, particularly, shell-quote-argument, because I think the current code is forcing Windows users to use the cmd shell.

In fact, I did not see such a problem before Emacs 24.3. There might be some changes since then. In addition, there is a 10-years old post in
http://lists.gnu.org/archive/html/emacs-devel/2005-03/msg00313.html
talking about the similar problem, and the lister mentioned
" 
It seems very usual for emacs users on w32 to use cygwin or mingw.
Right now shell-quote-argument would return something wrong when bash
or some "intelligent" shell is used on w32 because it assumes a dumb
w32 shell.
"

I am no expert in this this fundamental lisp model of subr.el, and the consequence of changing it. That's why I am reporting this as a bug in the hope some higher experts could lend some help.

Thanks.

I use python mode (python.el) for some python programming. When I invoke
the command python-shell-send-buffer, my Emacs always reports "Searching
for program: no such file or directory,
c\:/Anaconda3/Scripts/ipython.exe".

I traced down the cause of this problem, and found the following lines
in python.el:
(defun python-shell-parse-command () ;FIXME: why name it "parse"?
"Calculate the string used to execute the inferior Python process."
;; FIXME: process-environment doesn't seem to be used anywhere within
;; this let.
(let ((process-environment (python-shell-calculate-process-environment))
(exec-path (python-shell-calculate-exec-path)))
(format "%s %s"
;; FIXME: Why executable-find?
(shell-quote-argument (executable-find python-shell-interpreter))
python-shell-interpreter-args)))

The function call 
(shell-quote-argument (executable-find python-shell-interpreter))
changed the path of my python interpreter from
"c:/Anaconda3/Scripts/ipython.exe"
to
"c\\:/Anaconda3/Scripts/ipython.exe".

I worked around this problem by replacing the function call
(shell-quote-argument (executable-find python-shell-interpreter))
with
(executable-find python-shell-interpreter) ;; edited by DZ on
2015/06/05: (shell-quote-argument) caused the problem of
"c\\:/Anaconda3/Scripts/ipython.exe"

To further analyze the problem, I found the function
shell-quote-argument defined in subr.el does not deal with the case when
bash from cygwin is used.

For the record, this is bug #20237.


I added the following lines in the cond statement, to solve the problem.
((and (eq system-type 'windows-nt) (if (string-match ".*cygwin.*"
(w32-shell-name)) t nil)) ;; DZ's edit on 6/5/2015
(if (equal argument "")
"''"
;; Quote everything except POSIX filename characters.
;; This should be safe enough even for really weird shells.
(replace-regexp-in-string
"\n" "'\n'"
(replace-regexp-in-string "[^-0-9a-zA-Z_./\n:]" "\\\\\\&" argument))))

I'm sorry, but I don't see how we can accept such a change: it means
that when the Cygwin Bash is used as the shell, the ':' character will
not be quoted, which I think could cause trouble in some cases.

Maybe some Bash expert could chime in and tell whether problems are
possible with Bash in this case.

Is there any way you could avoid using the Cygwin Bash as the shell
when running the native Windows build of Emacs?  That would make the
problem go away without any need for changes.

that when the Cygwin Bash is used as the shell, the ':' character will
not be quoted, which I think could cause trouble in some cases.

Maybe some Bash expert could chime in and tell whether problems are
possible with Bash in this case.

Is there any way you could avoid using the Cygwin Bash as the shell
when running the native Windows build of Emacs?  That would make the
problem go away without any need for changes.

Not an expert (and didn't read the rest of the report), but I can't think of a reason why ':' would need quoting in Bash (unlike eg ';' or '&'). What kind of thing are you thinking of?

PATH-style lists, maybe. Anyway, if we think ':' doesn't need to be quoted, how about removing it from the Posix branch of shell-quote-argument? Then we won't need ugly hacks that try to detect Cygwin Bash used from a native Windows Emacs.

The comment there says "This should be safe enough even for really weird shells." That's a much broader question than just Bash! :) But I thought of an example that affects Bash: scp localfile remotehost: If "localfile" contains ":", things will get confused. So it's probably best to leave it as-is.

That's a much broader question than just Bash! :) Let's stop escaping the : and if/when someone comes up with a very weird shell where this is a problem, we'll see what can be done.

(Sorry, it wasn't > clear from what you said.) Bash is always a pain to handle, there are exceptions in Tramp's code for that. But having a branch for this is not realistic for Tramp, because Tramp doesn't distinguish remote shells, it only expects that they speak a bourne-shell dialect.

The actual problem here is that python.el is using shell-quote-argument but then not using a shell. The result of python-shell-calculate-command (formerly known as python-shell-parse-command) gets passed to python-shell-make-comint as the CMD argument: (defun python-shell-make-comint (cmd proc-name &optional show internal) [...] (let* ((cmdlist (split-string-and-unquote cmd)) (buffer (apply #'make-comint-in-buffer proc-name proc-buffer-name interpreter nil args)) make-comint-in-buffer uses start-file-process, i.e., no shell is called. So python.el is trying to undo shell-quote-argument with split-string-and-unquote, this is the bug. To see this on any system, compare C-u M-x run-python RET 'python' -i this fails, while C-u M-x run-python RET "python" -i this succeeds (assuming you have python in exec-path).
