HOW CAN I STOP THIS NOVICE MODE STUFF?

[Bruce Korb]

Please?  I hate it.  This one seems unstoppable and won't even
let me paste it in.  Emacs really does not know better than me.
I DO NOT WANT TO SEE THIS STUFF.

The local variables list in gnupload
contains variables that are risky (**)

Do you want to apply it?  You can type
y  -- ...
n  -- ...

 ** like hell.  Just do what you are told and leave me alone.
    You won't even let me copy and paste the message because it
    is in a buffer that gets erased and the emacs mode is such
    that the absolutely only allowable thing is to type "y" or 'n'
    because it is so crucially important that you must disrupt my work.

So you want to allow everyone to erase all your files?

Hi Andreas, Lennart,

"anyone", I would hope :).  Perhaps I was mistaken.  I thought
these incantations were constrained to setting buffer local
variable values.  If they can execute arbitrary emacs lisp code,
then it sounds very Microsoft-like.  ``Let it be easy for
content providers and painful to secure.''  If emacs has really
become "that powerful" then there's nothing for it but to go
back to old versions or back to vi.  I disliked vi in 1974,
despite "ed" being the only competition.

C.F. ``See "(info ...)" and "Ch-v v enable-local-variables'', I
am afraid that does not address this issue.  Extracted from .emacs:

  (setq enable-local-variables    't)
  (setq enable-recursive-minibuffers 't)
  (setq hack-local-variables      't)

Cheers - Bruce

Hi Bruce, can you please tell what you think is not explained? Did you 
read what the value t means for enable-local-variables?

Even if they were: there are some buffer-local variables (for syntax
highlighting for example) whose subexpressions are evaluated. And, there
are local hook variables which contain Lisp code as well. So, even if
enable-local-eval is disabled (as it is by default), you could use
"backdoors" to introduce your own Lisp code by setting the right local
variables.

Therefore, every local variable that is not marked as safe-local-variable
(by the packages that declares it) will cause an "annoying" warning (which
gives you an option to ignore it the next time). On the other hand, a
variable is marked as risky-local-variable, the option

!  -- to apply the local variables list, and permanently mark these
      values (*) as safe (in the future, they will be set automatically.)

will not show up, so you will be asked over and over.

So, to avoid these messages, the best way IMHO is to ask the package
maintainer to mark the variable you want to set in your local variables as
safe.

You can disable the local variables stuff completely, if you think it is
too insecure.

a) you do not need to quote t, it will quote itself
b) t and :all is not the same
c) you do not need to quote :all either :)

You can add the variable and its value to safe-local-variable-values if you
do not want to allow all variables.

    variable values.

Yes, but there are variables whose values can get evaluated by Emacs
commands.  That's the motive for this feature: to make sure those
variables don't get set by some file to a malicious value.

And the net result is a loss of usability because at least I do not
appreciate being interrupted from my work to answer "are you sure"
questions on files I open and close a fair amount.  The "you've never
set this kind of variable before, do you really want to do that?!?!?!"
question is a nuisance because I don't really want to enumerate
everything, but this one is a bigger hassle.  Perhaps add something
like:

/*
 * Local Variables:
 * .....
 * user-approves-of-everything: bkorb
 * End:
 */

and then just not ask questions of "bkorb" would take care of this?

Anyway, today's question has to do with some other setting that is
not readily solved with googling for

   emacs "does not run" in "separate window"

I can, in fact, C-x 5 2 and create another window and then Alt-F4
kill off the original window, but I'd rather have (emacs &) simply
spawn another window.  There must be some setting that changed, but
there sure is no obvious setting that I know about.  Disabling the
"~/.emacs" config file has no effect.  Googling got me to someone
suggesting a different OS/X binary, but nothing else of interest.
What should I be looking for?  Thank you - Bruce


P.S.  In case it helps, .Xdefaults:

Emacs.font:         7x13
Emacs.BorderWidth:  0
Emacs.geometry:     81x100
Emacs.MenuBar:      off
Emacs.ToolBar:      off
Emacs.VerticalScrollBars:   left

But none of this has changed in the last couple of weeks

Can you please post the contents of the local variables section for the
file that causes this?

It is not germane because I refer to any such variable,
but most especially to those that are unfixable and trigger
this ``Do you want to apply it?'' unsuppressable message.

Anyway, here you go:



(defun hack-local-variables-confirm (vars unsafe-vars risky-vars)
  (if noninteractive
      nil
    (let ((name (if buffer-file-name
		    (file-name-nondirectory buffer-file-name)
		  (concat "buffer " (buffer-name))))
	  (offer-save (and (eq enable-local-variables t) unsafe-vars))
	  prompt char)
      (save-window-excursion
	(let ((buf (get-buffer-create "*Local Variables*")))
	  (pop-to-buffer buf)
	  (set (make-local-variable 'cursor-type) nil)
	  (erase-buffer)
	  (if unsafe-vars
	      (insert "The local variables list in " name
		      "\ncontains values that may not be safe (*)"
		      (if risky-vars
			  ", and variables that are risky (**)."
			"."))
	    (if risky-vars
		(insert "The local variables list in " name
			"\ncontains variables that are risky (**).")
	      (insert "A local variables list is specified in " name ".")))
	  (insert "\n\nDo you want to apply it?  You can type
y  -- to apply the local variables list.
n  -- to ignore the local variables list.")
	  (if offer-save
	      (insert "
!  -- to apply the local variables list, and permanently mark these
      values (*) as safe (in the future, they will be set automatically.)\n\n")
	    (insert "\n\n"))

Things to note:

1.  There is no convenient way to just hush the thing up and tell it,
    "I do not mess with untrustworthy files.  Leave me alone."

2.  Sometimes, even "offer-save" is false, so the possibility of
    saying "don't bother me with this any more" is not allowed.

What do you mean by, "not allowed"?  I know my wants and needs better
than any silly program.  Really.  I do.  Perhaps I should replace this:

(defun hack-local-variables-confirm (_v _uv _rv) #t)

Yes?

It is, please send the list of variables that you have issues with.
If such variables are defined in emacs itself, then the policy is to
determine what type of arguments are safe for the variables. If the
variables are defined in a package, then it is that package's duty to
mark them as safe.  
The above is the current policy.

Unless you show that the policy is somehow wrong, you'd have trouble
convincing people to change it (which is what you propose).

One way to try to show that the current state of affairs is wrong is to
show actual example where this happens.

Just my 2 cents.

How does "the package" do that?  If the gnulib project doesn't
do this, then which package providers actually do know the code?

What I think I am asking for is documentation on how to make this test:

     (eq enable-local-variables :all)

yield "#t" (or however it is spelled in emacs lisp).
Would that be:

      (set enable-local-variables  :all)

in my .emacs file?  Another part of my request is that I think it
is a little over the top to have to delve into the emacs lisp code
to the point were I found the ``(eq enable-local-variables :all)''
test at all.  :(

I'm certain I'm well into the dollars by now.  ;-)

Fro example
(put 'VARIABLE_NAME 'safe-local-variable 'integerp)
for a variable that is of type interger. There are many examples of this
in the emacs source code.

I can't parse this.

As I said in my previous email there's no way to do this and AFAIK no
desire to do it because it does not seem necessary. If you want this to
change you'd have to show it is necessary.  Precise examples of problems
would be a good start for a proof.

Hmm, so gnulib is a library (never heard of it before). I downloaded it
and looked at all the Local Variables section in all the files. Some of
the variables used were not marked as safe in Emacs, this was causing
warnings. I marked them as safe on the emacs-22.2 CVS branch. It will
get merged into CVS HEAD soon.

The only issue left with the local variables in gnulib is: 
# eval: (add-hook 'write-file-hooks 'time-stamp)

This cannot be marked as safe as it is.
Does anyone know if we already have a solution for something that
updates the time stamps when saving?
If not, do we want to add such a solution?
What would that solution be?

(setq enable-local-variables :all) could do it, but that is a really
bad idea.  It means that a nasty file sent to you, which you then
visit in Emacs, could make your Emacs do anything at all.

    The only issue left with the local variables in gnulib is: 
    # eval: (add-hook 'write-file-hooks 'time-stamp)

Bruce, you can add this to `safe-local-eval-forms'.  Does that work
for you?

Maybe we should add it to the default value of
`safe-local-eval-forms'.

IMO we should. config.guess and config.sub use that form. Luckily very
few people need to edit those files...

I have done that as per your request. (on the EMACS_22_BASE branch)

Bruce, do you get any other unsafe variable warnings?

At the moment, no.  Thank you.  I just updated to GNU Emacs 22.1.1
and plodded my way through variable after variable triggering the
"we've never set this variable before.  Are sure you want to do
this?" over and over and then I hit this one that wouldn't allow
me to say, "YES! Now, leave me alone!!".  It did get rather
repetitive and irritating, even with just the ones I was "allowed"
to hush up.

Again, thank you!

Can you find the list of the ones you accepted, and send it to us?
Maybe we should mark some of them for acceptance by default.

Hi Richard,

I have a "safe-local-variables-values" both at home and at work.  For some
administrative reason, my work one got reset to empty and now only
contains:

'(safe-local-variable-values (quote ((sh-indentation . 2)
(sh-basic-offset . 4) (sh-basic-offset . 2))))

But I'd simply say that anything containing "indent" or "offset" is
pretty likely
to be "pretty safe".  I still think it is better still to "allow" me to say that
this is a nifty feature that I don't like.  :)  I want to live
dangerously because
I don't edit files that might do such nasty things.  Thinking along those lines,
it might make more sense to be able to say "in this file hierarchy, I trust
everything" and "in that file hierarchy, I don't trust a thing."  I
just have little
use for the latter.

Cheers - Bruce

P.S. Have I mentioned that I have really liked using emacs since 1984?  :)

c-indent-comment-alist

sh-indentation is already marked safe.
sh-basic-offset still needs to be marked as safe. I'll take care of it
soon.

What we are trying to do is actually for users not have to care about
this, it should work without any action. For that we are trying to mark
as many variables safe as possible.

Maybe we can ask people on the emacs mailing lists to try to help with
this.  Find any variable not marked as safe that is used in any local
variable section in the code that they have access to.

Additional, maybe an option to report all such variables (using
`reporter.el') would be useful?

The former already has a property by default.
I will add it to the latter.

    But I'd simply say that anything containing "indent" or "offset" is
    pretty likely
    to be "pretty safe".

Likely, but not certain.  We have decided to be conservative here.

My home version:

I fixed this one on Jan 3rd in the emacs-22.2 branch. You won't see it
after the next release.

I think these might be mistakes, it should have "mode", not "Mode". Can

It's interesting that you get so many duplicates in the list. That might
point to a possible problem in the code that deals with
safe-local-variable-values.

These should work.

Not sure why you got those

This still needs fixing. Alan can you please mark
c-font-lock-extra-types type to be safe? (not sure what the right
predicate is)

Well, there's not much we can do about that. We can't offer to fix
issues in the past. The GNU Time Machine project it a bit behind
schedule (or ahead?).

I got them because I sedded 'em out of all files containing the string
'Local Variables:'
It wasn't that "mode" and "minor-mode" were added to the "they're okay
now" list,
but that they got extracted with the grep/sed/awk/sort script.  :)

That sounds about right.   :)  It really stands as a caveat about
changing behavior.  It causes folks to stumble for years on end
before fixes propagate through all the layers.  Heck, I still have
to concern myself with shell anachronisms that were cleaned up
in the early 80's.  Solaris' /bin/sh is rather extreme though.

Thanks for fixing this stuff up for whenever I eventually see it.  :)

I extracted those names from text found between 'Local Variables:' and
'End:' lines, so autotools is using it down there and not in the -*- line.
Leastwise, they are _trying_ to use it there.

I expect it works in both places.
Anyway, if it causes Emacs to ask for confirmation, please report.

    Don't know about this one.

`coding' is a "fake" variable you can specify in the -*- line to
specify the file's coding system.  If specifying that "variable"
causes questions, please send a precise test case and we will debug
it.

The `unibyte' pseudo-variable does cause a question.

    It's interesting that you get so many duplicates in the list. That might
    point to a possible problem in the code that deals with
    safe-local-variable-values.

I looked at the code, and I don't see anything that could cause the
duplication.  The only place that changes the value does it with
`add-to-list', which tests using `member'.

No need to shout.  And this is not a bug, so please post such requests
to help-gnu-emacs@gnu.org instead.

And BTW you could copy the buffer if you were an expert:

M-x toggle-debug-on-quit

and then just press C-g at the prompt. Copy the stuff and [c]ontinue from
the Lisp debugger.
