Just type

  M-x eww http://jblevins.org/projects/deft/ RET

and Emacs uses up 100% of CPU, reacts to user input once in a few seconds.

I can recreate this bug in emacs -Q. Here is my build info.

Emacs version: GNU Emacs 25.0.93.1 (x86_64-unknown-linux-gnu, GTK+ Version
2.24.23)
 of 2016-05-02, built using commit ec554d7741d2ff2828ecaa437cc26a6e615f1319.

I don't know exactly at what point the backtrace is useful. But here is the
backtrace I got after I got control back in gdb after hitting C-g multiple
times in emacs while it was frozen:

It's displaying an animated GIF that seems to take all of Emacs' time.

I wonder what the best thing to do here is...

First of all: Can the animation function determine that it's making
Emacs unresponsive?  I guess it could keep track of how much time is
passing between each time it's called, and if that's longer than the
timeout, it should ... postpone itself a bit further to allow some
keystrokes to get in between each frame?

That would slow down the animation even further, but make Emacs more
responsive, so I think that should probably be done.

The other thing is that the ImageMagick animation thing I implemented is
s-l-o-w.  (And eww is using that instead of the GIF animation, since GIF
doesn't allow rescaling.)

If somebody could take a peek at imagemagick_compute_animated_image and
make it much, much faster, that would be really nice.  :-)

Can you show how that function is called on the Lisp level?

For 25, perhaps it might make sense to default to not animating images?

It's the `image-animate-timeout' function in image.el.

(defun image-animate-timeout (image n count time-elapsed limit)

[...]

	   (delay (max (+ (* (or (cdr animation) image-default-frame-delay)
			     (/ 1.0 (abs speed)))
			  time (- (float-time)))
		       image-minimum-frame-delay))

[...]

      (unless done
	(run-with-timer delay nil 'image-animate-timeout
			image n count time-elapsed limit)))))

So I think it shouldn't be too difficult to ... do something useful
here...

So you are saying that a single call to image-animate-timeout takes
much longer than the value of 'delay'?  (Which is what typically,
btw?)

No, I don't want us to do that.  The problem is not so bad in an
optimized build, and Emacs is not really stuck, it still responds to
keyboard input.

In any case, let's first see what it takes to fix this.  Perhaps the
fix is so simple we can allow it in Emacs 25.1.

Well, `image-animate-timeout' doesn't really do much, but if the next
timeout arrives much later than `delay' specified, then we can surmise
that displaying the next image in the sequence took a lot of time.

Most parts of the image formatting doesn't happen until redisplay
happens -- `image-animate-timeout' just increases the image index, and
then redisplay does all the hard lifting.

While redisplay is doing all that, Emacs isn't allowing any events to
fire, I think, so we should be able to see that Emacs is busy...

> (Which is what typically, btw?)

I think for most GIFs it's typically 0.1s, but it can be larger.

But why would display of an image be so slow?  It isn't slow with
simple GIF images.  What am I missing?

I see the animation run at about 1 to 2 Hz refresh rate, so I don't
think redisplay is slow.

Which might be too small.  How about making it 0.5 sec or even 1 sec
instead?

Computing animated images is more complicated.  And see the comment I
made about ImageMagick animation implementation.

I get one refresh at, like, once a second on the example image (with
ImageMagick).

The animated image sets the delay between images.

In what way?

Not relevant for what I see here: my Emacs is built without
ImageMagick.

Each frame is a composite of the previous frames and the current frame
in the image.

But anyway, this is all besides to point:  The question is still whether
we can detect that the animation is making Emacs slow, and whether
injecting some more delay (dynamically) into the animation timeout will
fix it.  I think somebody will just have to try.

Any idea why is image-multi-frame-p do expensive?

Shouldn't we first understand why Emacs is so slow?  See my message

Hm...  No, I would have expected that to be fast.  It's basically just a
call to `image-metadata', isn't it?  And that should be caching the
data, I think?

Hm...  That function basically just does:

      struct frame *f = decode_window_system_frame (frame);
      ptrdiff_t id = lookup_image (f, spec);
      struct image *img = IMAGE_FROM_ID (f, id);
      ext = img->lisp_data;

Yes, you are completely right.  I thought I had looked at this a year
ago and determined that it was just slow because decoding the animated
image was slow, but if it's due to something else, that would be nice.

I didn't see anyone mention yet that the gif on that page seems kind of dumb.
It's 2036x1426, but is resized to never be more than ~ 1/4 of that size
even in a full-screen Firefox. So I don't think that gif by itself is
too indicative.

Yeah, it's an extreme GIF, but Emacs shouldn't become (almost) unusable
in the presence of such images...  I mean, you have to kill the eww
buffer to get anything done.

You can get pretty much the same effect by visiting a page that contains
a number of smaller animated images.

Right, but it's not like this is new in 25 or anything, it's always been
like that.

Oh, yeah, it's always been bad.  People just notice more now that Emacs
has a web browser.  So I think it's unlikely that whatever we do about
this is code is something that'll go to emacs-25.  Unless there turns
out to be a very simple thinko somewhere.

I've now run a longer profile, with image.el loaded (not .elc), and
the profile is this:

    - image-animate-timeout                                        2858  88%
     - if                                                          2858  88%

IOW, it insists that the problem is in the call to image-metadata.
Which probably mean most of the time is spent in lookup_image?

Can you run Emacs under prof to see what happens on the C level?

Btw, if I wait for a while (maybe 20 sec), the slowness disappears,
and Emacs becomes responsive again, although the animation still goes
on.  So perhaps what causes this is some initial processing?  (I have
no idea what's involved in displaying an animated GIF.)

After Emacs has decoded all the frames in the image, they'll then be
stored in the Emacs display image cache (the one you can clear with
`clear-image-cache'), so Emacs should be responsive after the animated
GIF has looped once.  (Unless there are more frames in the image than
the length of the Emacs image cache.)

Yes, I'm sure I'm not the only person who's changed his working habits to
use eww for a number of daily tasks.  In my case, it's due to the easily
accessible "&" binding -- such a simple idea, and it's what made eww useful.
(I was using w3m before, but never as much as I use eww now.)

The consequence is that we use eww on random, uncontrolled pages on
a regular basis, and if it causes Emacs to hang, that's really annoying.
In some sense, eww is a victim of its success -- we're not interested in
new features, we've got "&" for when eww fails, but we're very much
grateful for any improvement in stability and performance.

Ceterum censeo bugum 17976 saciendum esse.

Thanks for your help,

-- Juliusz

Hm...  the only "prof" on this system is "prof - secondary structure and
solvent accessibility predictor" which is probably not the one.  :-)

Never mind.  I googled a bit.

Here's what gprof says.  This is with the gif instead of ImageMagick:

In any case, adding a sanity check is probably a good thing.  For
instance: If the timer is being run more than (say) two seconds after
the target time, then Emacs must be busy with something.  In that case,
we should probably stop animating the image, and tell the user.

I've now pushed a fix that does this to the trunk, which make the test
case usable for me.  That is, after hanging for six seconds, since
that's how long it takes for Emacs via ImageMagick to render the first
frame.

`image-map' can have a command to start the animation again, for
instance.

Which means that the heavy part is decoding, and not redisplay.

If the OP agrees that the issue is solved on master, we can close the
bug.

Thanks.

Sure, I'm very grateful for the fix (I'm impatiently waiting for it to
migrate into the 25 branch).  But what about the 6-second hang, which I can
reproduce even with with shr-image-animate set to nil?  Should decoding of
large images happen asynchronously, or is shr not designed for that?

Thanks, so is it okay to close the bug?

It most probably never will.

We don't have infrastructure for doing this asynchronously.  If the
concurrency branch ever gets revived and merged, such jobs might be
good candidates for using that facility.  Otherwise, no, it isn't
possible.  It's not shr that is not designed for that, it's Emacs
itself.

I think it's quite likely that we can implement ImageMagick support in a
more efficient way than Emacs currently does.  If you compare how long
time the "display" command uses to display an image (and that's a pure
ImageMagick app) with Emacs when displaying via ImageMagick, the
difference can be striking.

So if somebody familiar with the ImageMagick C interface could go over
the Emacs code, I think it's likely that we could see great improvements
here.

preview-latex shows images in a (La)TeX buffer asynchronously. Can't we
*cough* simply *cough* do the same here ?

(see also David Kastrup's message at
https://lists.gnu.org/archive/html/emacs-devel/2014-09/msg00893.html and
some of his explanations elsewhere in that thread for details on how
preview-latex work. I didn't investigate much myself.)

Hm.  So I thought.  But then I tried displaying the test image here in
with "display", and for the first frame to pop up, it took...  six
seconds, which is the same amount of time that Emacs uses.

Ok, there's nothing we can do here to improve the situation.  Except
implement image scaling ourselves, so that we can use the giflib library
to decode the GIF, and then scale it afterwards.  Which should be
doable, but is outside the scope of this bug report.

Sure, but that doesn't change what I said.  It's the programmer who
decided to trigger decoding from redisplay.

AFAIK, it does that by running a separate program that produces an
image that Emacs then shows in display properties.

> Can't we *cough* simply *cough* do the same here ?

Maybe, I don't know.  With what external program?  Patches welcome,
anyway.

(Although I must confess that doing display related stuff in a
separate program is IMO a terribly ugly design.)

It's too late for such changes to be backported to emacs-25, and the
next release after that will most probably start from master, not from
emacs-25.
