Emacs installed via homebrew (--with-cocoa enabled) freezes with 100%
CPU usage when opening a file that contains unicode emojis. Other
editors handle the file just fine (and default mac emacs opens it, but
doesn't display emojis).
Steps to reproduce:
1. emacs -Q
2. open a file that contains a unicode emoji (my test file has a burger icon in it - 🍔)
3. emacs will stop responding and keep the CPU at 100%

Is there a way to at least not display emojis (I’m fine with blocks)? Thank you in advance

It doesn't freeze here, so it's something NS specific, I guess.

I can’t reproduce this with the master branch. Are you sure it’s just
the presence of the emoji and not something else?

I used this command to create a test file:

    echo "🍔" > /tmp/test.txt

> Is there a way to at least not display emojis (I’m fine with blocks)?

GUI Emacs doesn’t display emojis. It’s possible homebrew have included
a patch to enable them.

Can you test with a build direct from git, or a nightly build from
emacsformacosx.com?

Tried downloading from emacsformacosx.com <http://emacsformacosx.com/> (both the nightly and the stable version), still have the same issue - I’ve also recreated the file with your echo command. Not sure why it breaks like this, since the preinstalled emacs opens the file just fine. 
What I did notice is, it seems to allocate a bunch of memory every second or so when opening that test file (looking at activity monitor -> Info about the process); before I force-killed it, it was taking up 2,39GB of ram and it didn’t seem like it would stop.

I’m attaching a sample of the process, maybe this can be of help. 

Thanks for trying to help!

The preinstalled Emacs is ancient. Version 22 or something. Quite a
lot has changed since then. It also only works in the terminal so the
glyph display code is completely different.

I don’t really understand what that’s telling me. Is it possible for
you to run it under a debugger and send me a backtrace?

You’ll probably have lldb installed already, so all you need to do is
run

    lldb /path/to/emacs
    > run

and once it freezes hit ctrl‐c and

and send me the output.

You are running it in GUI mode, and not in the terminal, right?

I’m running in gui mode yes. I’ve ran it from lldb, attaching the backtrace. 

Thank you for taking the time

It looks like it’s going into a loop while trying to build a list of
available fonts.

I can’t remember if you said you’d tried this, but please try running
Emacs with the -Q parameter. This bypasses your configuration so we
can be sure it’s not something in there.

Yeah, I tried running with -Q; I’ve also reran it from lldb with this arg, attaching the backtrace. I’ve got quite a few fonts installed, could that be an issue?

Thanks again for looking into this

Is it possible to post the backtrace here?

Also, please always use "Reply to all", so that the bug address is
CC'ed, and everyone sees the discussion.

I thought I did, but I might be mistaken. Re-sending the backtrace.

Thanks.

Alan, I don't think I understand how you reached your conclusion: all
the loops involved in the code shown in the backtrace are fixed-size
loops, so they've got to end at some point.  Am I missing something?

No, I just saw that the last piece of Emacs code in the backtrace was
macfont_list and figured it was probably something to do with that,
but presumably the loop could be somewhere else.

On macOS there is specific code for displaying colour emojis, but it’s
been disabled. I don’t see any emojis at all, just a blank space the
same size as the colour emoji should be.

I don’t know if Macs come with non‐colour emoji capable fonts by
default, all other Mac apps display the colour ones so I can’t even
see a way to test.

If I call describe-char on the hamburger I get:

             position: 146 of 146 (99%), column: 0
            character: 🍔 (displayed as 🍔) (codepoint 127828, #o371524, #x1f354)
    preferred charset: unicode (Unicode (ISO10646))
code point in charset: 0x1F354
               script: symbol
               syntax: w 	which means: word
             category: .:Base
             to input: type "C-x 8 RET 1f354" or "C-x 8 RET HAMBURGER"
          buffer code: #xF0 #x9F #x8D #x94
            file code: #xF0 #x9F #x8D #x94 (encoded by coding system utf-8-unix)
              display: no font available

Character code properties: customize what to show
  name: HAMBURGER
  general-category: So (Symbol, Other)
  decomposition: (127828) ('🍔')

There are text properties here:
  fontified            nil

I don’t know if any of this is relevant.

So maybe the loop is macOS specific.

It's strange that you see "just a blank space", though, because this:

>               display: no font available

means Emacs should have displayed a box with the hex code.

Can you try installing Symbola?  That's the font I see being used here
for this character.

Alan, it might help to add some printf in macfont_list that would log
on a file all the fonts that are being scanned there.  Maybe that will
give some hint.

Now I’ve installed Symbola I get mono emojis in Emacs. There also used
to be a one second or so pause when opening a file with an emoji in
that has now disappeared.

Nejc, can you install Symbola if it’s not already there and see if
that makes a difference?

Now that’s interesting, now it works - opens the file and displays black&white emojis. Thank you all so much for your help! :-)

(though, not having a font installed probably shouldn’t mess it up like this, or am I wrong?)

My understanding is that if you have Symbola installed it’s one of the
first fonts Emacs checks for emoji. If you don’t have it installed, or
Emacs can’t find the glyph it’s looking for, then it searches other
fonts for them.

I think that means you’ve probably got a font that doesn’t get on well
with Emacs. We should be able to find out which one if you’re willing
to try building a custom version which prints out each font family as
it tries them.

I don’t know if it’s worth doing.

That's right.

I think it means that the freeze wasn't a freeze, but just a very long
search for a font that could support the character.  It was made even
longer by using up a lot of memory, which caused paging and slowed
Emacs down.  Not sure why it used up so much memory, perhaps that's
due to some very large font, or maybe it's a bug in the macOS code
which is involved in the search.

Having Symbola installed is a Good Thing anyway, because Emacs by
default will try to use it for many unusual characters.

I tried reproducing this on Catalina with Emacs 28, and I was unable
to -- Emacs didn't find a font for the burger symbol, but there was no
noticeable delay while looking for the font.  (After installing Symbola
it displayed the character correctly.)

So I'm going to go ahead and guess that this has been fixed now, and I'm
closing this bug report.  If anybody's seeing this on a modern
macOS/Emacs combination, please respond, and we'll reopen.

That depends on how many fonts you have installed.
