I've used MH and Emacs to read the insane quatitites of mail I get
for many years.

With latest upgrade, I now get rubbish like:

Opening TLS connection with `gnutls-cli --insecure -p 443 ...

Which I certainly do not want (else I'd be using a browser to read mail).
^G won't stop it and a 2nd ^G makes emacs want to core dump!

After googling a bit I set

(setq starttls-use-gnutls nil)
(setq mm-discouraged-alternatives '("text/html" "text/richtext"))

but it is still doing it.

How do I tell Emacs that under absolutely no circumstances do I want it
to do this?

I can remove gnutls-cli, but then it falls back to openssl - which I
cannot remove.

Thanks

What exactly is that "this" that you don't want Emacs to do?  It's
hard to help without understanding which part of what you described is
the problem.  (Maybe it's because I don't use MH-E; but TLS
connections are in Emacs core, not in MH-E, which just uses it.)

Thanks.

Sorry, I was refering to the opening of urls (tls or otherwise)
especially before I've had a chance to even see what they are.

That's a serious attack vector and why I would never choose an html
enabled mail reader.

Unfortunately my mail reader of choice (for the last 20 years or so;-)
seems to have morphed into one.
I'm hoping that that can be turned off.

Sorry, mh-e may be a red-herring.
I want to prevent Emacs from opening http[s] urls - at the very least
while scanning mail that I've not even been able to read yet.

Thanks

Perhaps shr-related.

http://sourceforge.net/p/mh-e/bugs/478
http://debbugs.gnu.org/21519

As always, a minimal example starting from emacs -Q would be helpful.

This message seems to come from `open-tls-stream' (in lisp/net/tls.el),
so it would be useful to have a backtrace from there.

E.g., instrument the function with edebug-defun and then type `d' when
a call to `open-tls-stream' activates edebug, see (info "(elisp) Edebug Misc").

OK, it's clear now, even to me, thanks ;-)

You've got several suggestions for how to present additional
information about what triggers the URL access.  I think that
information will allow us to help you disable this.

In generally, I'd expect to see some option in MH-E to disable this.

Thanks for the pointer!

shr-blocked-images doesn't appear to be in scope, but
gnus-blocked-images was and setting that to "."
Appears to have stopped at least the most recent offending mail item
from attempting to connect somewhere.
[Unless the fact that it was previously read is relevant]

Looks like the offending item is indeed an img url.
Some people think e-mail is incomplete without corporate logo's and
similar noise.

MH-E doesn't render HTML directly, so the options would be in the gnus
(and below) libraries.

I'm working on adding a user-visible control for use with shr: never
display images, only display local images (i.e., ones that are included
with the email), or display all (local and remote) images.

It should be possible to inhibit all image display by setting
gnus-inhibit-images to a non-nil value.  See 
http://sourceforge.net/p/mh-e/bugs/478/ for further discussion.

Another workaround would be to change mm-text-html-renderer (e.g., set
it to 'w3m-standalone).

After some discussion with Bill Wohler, I've looked more carefully at
the problem, paying more attention to the overall system design and
layering.

MH-E uses the MIME (mm) libraries to render emails.  There is a variable
mm-inline-text-html-with-image which, according to the documentation,
should be sufficient to disable downloading of images.

  mm-inline-text-html-with-images is a variable defined in `mm-decode.el'.
  Its value is nil
  
  Documentation:
  If non-nil, Gnus will allow retrieving images in HTML contents with
  the <img> tags.  It has no effect on Emacs/w3.  See also the
  documentation for the `mm-w3m-safe-url-regexp' variable.

Unfortunately, shr does not honor mm-inline-text-html-with-images.
Instead, it uses #'gnus-blocked-images as its control (see #'mm-shr).

MH-E could temporarily rebind gnus-blocked-images before calling
#'mm-display-part.  But really, that's a hack to work around the fact
that the documented mm API doesn't work.

For email, it appears that a simple binary control is all that's needed
(either fetch remote images or not).  So it seems like it would be
straightforward for #'mm-shr to use mm-inline-text-html-with-images, and
for Gnus to set mm-inline-text-html-with-images as needed.

But for newsgroups, it looks like finer control is desired.  So I don't
know what the fix should look like.  But MIME libraries are documented
as general-purpose, rather than private to Gnus.  So this really ought
to be resolved at the mm layer, rather than adding renderer-specific
tweaks to MH-E.

Sounds absolutely right.

The first step should be anyway to fix mh-cl-flet[1], recompile
mh-e, and see how the behaviors change, I think.

I don't see how that's relevant to this issue.
mm-shr _always_ consults gnus-inhibit-images and gnus-blocked-images,
using them to override shr-inhibit-images and shr-blocked-images.
If mm-shr is supposed to be a general purpose facility for use by things
other than Gnus (?), this seems obviously wrong.
Surely Gnus should make whatever buffer-local shr-related settings it
needs in its Gnus buffers, and the MH-E folks can do the same, rather
than hard-coding Gnus-specific behavior in mm-shr?

(I'd actually say that the use of mh-cl-flet in mh-display-emphasis
seems like the wrong solution as well. MH-E should rather have asked
Gnus to provide an option so that article-emphasize can do what they
want.)

Sorry, I'll make time to look into *this* issue.

By the way, I've made your suggested mh-cl-flet fix to MH-E (thanks!!!)
and am letting it bake. I'll try to make some time to check it in this
weekend since I haven't noticed any ill effects.

My solution is below.  Tested briefly.  This patch moves the
binding of shr-inhibit-images and shr-blocked-images to Gnus
from mm.  So, MH-E has to do a similar thing.

I disagree. This only works for shr and defeats encapsulation.

mm-text-html-renderer can also be gnus-w3m, w3m, emacs-w3m,
w3m-standalone, links, lynx, w3, and html2text. The solution should be
encapsulated in mm and work for all of those renderers rather than
duplicating an incomplete solution in Gnus and MH-E and elsewhere.

Alternatively, the solution can be applied to each renderer that is
missing that functionality.

In any event, Gnus and MH-E are not the correct level for this solution
since we delegate to mm to do the rendering.

I think what makes this a non-trivial problem is wanting more
flexibility than just a binary yes-no decision, which is what
mm-inline-text-html-with-images currently provides.  That's why
gnus-blocked-images is a regexp (or a function that returns a regexp).

Could mm-inline-text-html-with-images be generalized to be more like
gnus-blocked-images?  (For example, nil means don't retrieve anything, t
means retrieve everything, a string would be a regexp of what URLs will
be retrieved.)  Then shr could use mm-inline-text-html-with-images
instead of shr-blocked-images, and MH-E users would have a single knob
that could control any of the different rendering back-ends.

Ok, I was too near-sighted yesterday.  Here is a second try:

Implement the new user options in mm:
`mm-html-inhibit-images' --- boolean
  Non-nil means inhibit displaying of images inline in the article body.
  The default is t.
`mm-html-blocked-images' --- regexp or nil
  Regexp matching image URLs to be blocked.  The default is "".

Make `mm-inline-text-html-with-images' an obsolete variable alias
for `mm-html-inhibit-images'.

How Gnus does when calling an mm function:

(defun gnus-function ()
  (let ((mm-html-inhibit-images gnus-inhibit-images)
	(mm-html-blocked-images (with-current-buffer gnus-summary-buffer
				  (gnus-blocked-images))))
    (mm-function)))

MH-E doesn't have to do like this if there's no need to have
options like `mh-inhibit-images'.

That's all.  Is this the right approach?

In Gnus, shr and gnus-html are controlled by both inhibit-images
and blocked-images, and w3m is controlled by only inhibit-images.
MH-E doesn't use gnus-html.el, does it?  As for mm-shr, it would
have to be changed into:

This looks okay to me.  And the default looks safe.

Just to confirm, mm-html-blocked-images would block the downloading of
remote images, but images that are embedded in the email and referenced
using a cid would still be displayed?

> Make `mm-inline-text-html-with-images' an obsolete variable alias

I'm afraid I don't understand well enough how variable obsolescence
works in Emacs to be sure.  
mm-inline-text-html-with-images is documented in terms of retrieving
messages, and non-nil means to allow retrieval.  mm-html-inhibit-images
would apparently control display of any images (even ones embedded in
the email), and non-nil means *not* to display.

> MH-E doesn't have to do like this if there's no need to have

Right.  We might want to add a note to the MH-E user guide that mentions
these variables.  But I don't think any changes are needed in the code.

> MH-E doesn't use gnus-html.el, does it?

I don't see any references, no.

thanks,
mike

Yes, it will be displayed unless `inhibit-images' is non-nil.
In that case, the url of the embedded data begins with "cid:",
and `shr-tag-img' doesn't see what `blocked-images' is.

I have `inhibit-images'=t and `blocked-images'=nil, so images are
not displayed normally, but do `W D W' (gnus-article-show-images)
only when I want to see those images.

Oops.  Sorry for my nonsense.  But I'd like to make it obsolete
anyway, since it is a very old option (that is what I made 14
years ago) and has been being used for only w3m.  I'll do:

(make-obsolete-variable 'mm-inline-text-html-with-images nil "25.1")

(defcustom mm-html-inhibit-images t
  "Non-nil means inhibit displaying of images inline in the article body."
  :version "25.1"
  :type 'boolean
  :group 'mime-display
  :set (lambda (symbol value)
	 (custom-set-default
	  symbol
	  (if (boundp 'mm-inline-text-html-with-images)
	      (not (symbol-value 'mm-inline-text-html-with-images))
	    value))))

The refactoring in Gnus and mm will probably be finished within
a week.

Regards,

Sorry, please let me make it supersede with:

(defcustom mm-html-inhibit-images t
  "Non-nil means inhibit displaying of images inline in the article body."
  :version "25.1"
  :type 'boolean
  :group 'mime-display
  :set (lambda (symbol value)
	 (custom-set-default
	  symbol
	  (cond ((boundp 'mm-html-inhibit-images) value)
		((boundp 'mm-inline-text-html-with-images)
		 (not (symbol-value 'mm-inline-text-html-with-images)))
		(t value)))))

This `:set' trick won't do the trick if this option is loaded
before a user sets the obsolete `mm-inline-text-html-with-images',
though.

That sounds good.

As for making mm-inline-text-html-with-images obsolete, that sounds fine
to me.

Great!  Thank you very much.

Done in the emacs-25 branch:

<http://article.gmane.org/gmane.emacs.diffs/134147>

Could you verify the changes?  Thanks.

Hi Katsumi, the diffs look okay to me, though I did notice one typo in
doc/misc/emacs-mime.texi:

> +be fetched and displayed.  For instance, do block all @acronym{URL}s

"do block" -> "to block"

I'll try building and testing the changes next, though I'm not sure how
far I'll get today.

thanks,
mike

Ah, thanks.  I've fixed it in both emacs-mime.texi and gnus.texi.

Everything works as specified.  Thanks!

I had missed the fact that mm-html-inhibit-images defaults to t.  That's
not my preference, but I don't have any compelling arguments in favor of
defaulting to nil.  Will you be creating a NEWS entry for these changes?

cheers,
mike

I changed my mind. :)  I'll make both mm-html-inhibit-images and
mm-html-blocked-images default to nil following Gnus' way (enabling
most features by default).

> Will you be creating a NEWS entry for these changes?

No sweat.

Changing mm-html-inhibit-images sounds good, thanks.  For
mm-html-blocked-images, leaving it at "" would follow Gnus' default
behavior for email, which is to not retrieve remote images.  I think
that's what we want.  If mm-html-blocked-images is nil, there's a
privacy concern, in that web bugs could be used to track when an email
is viewed.

Agreed.  I'll make it default to "" again.  In that case Gnus
users can use the `W D W' command (gnus-article-show-images) to
view images, that is what I do normally.  It would be better for
other packages to have a similar means as well, I think.

Yes, agreed.  I don't see anything like that for MH-E, so I'll open a
feature request for it.

Hi Simon, just to close the loop on the bug report that you filed: in
Emacs 25, MH-E will not download remote images by default.  Thanks for
reporting the issue.  If you have any concerns or questions, please let
me know.

thanks,
