Emacs occasionally crashes when displaying multi-lingual text.  It has
crashed several times in the last few days, such as visiting HELLO file
or browsing a web page with eww.  Sometime it crashes immediately when
the HELLO file is visited,  other times it crashes when I scroll the
screen.

Worth mentioning is that, to deal with font fallback, I have configured
a custom fontset:
  https://codeberg.org/m0p/dotfiles/raw/commit/62d1a6008c0e391a33239a809aee92e4c03f14b5/imports/not-nix-config-files/emacs-init.el


I can not reliably reproduce the crash. In most cases, the text in HELLO
would be displayed with a delay.  The backtrace is the following:

Thanks, but the backtrace you have provided is of no use to us, as
should have been apparent from the absence of information within.
Please follow the steps illustrated within (emacs)Crashing to transform
it into a complete backtrace incorporating both symbol information and
line numbers.

Either that, or start Emacs from GDB, and when it crashes type

  (gdb) thread apply all bt

and post here everything that GDB produces as result.

Thanks.

Regardless of our attempts to understand the immediate reason(s) for
these crashes and try preventing them, your setup, viz.:

  (create-fontset-from-fontset-spec
   ;; derived from standard-fontset-spec
   "-*-fixed-medium-r-normal-*-16-*-*-*-*-*-fontset-custom")
  (setq my-font-list
	'("NewComputerModernMono10"
	  "STIX Two Math"
	  "Noto Sans Mono CJK SC"))
  (dolist (font my-font-list)
    (set-fontset-font "fontset-custom" 'unicode (font-spec :name font) nil 'append))
  (add-to-list 'default-frame-alist
	       '(font . "fontset-custom"))

is not a good idea, to say the least.  Since 'unicode' is a script
that includes all the characters supported by Emacs, the above
basically tells Emacs that each of the 3 fonts you name support the
entire Unicode range of characters, and that cannot be right.

The correct way of customizing your fonts is set a single
ASCII-compatible font as the default font (in your case, this is
probably NewComputerModernMono10), and then use set-fontset-font to
add the other two fonts for specific scripts or ranges of character
codepoints, not for the entire Unicode space.  For each such font use
only the range of characters that it supports well, and that other
fonts don't cover or cover less well.

Regardless of this, we would still like to see a full human-readable
backtrace with your original setup, so that we could prevent those
crashes if that is feasible.

Emacs is supposed to be properly configured regarding fonts out of the
box.  If the default configuration somehow didn't work for you, please
describe the problems, and we will see if the defaults need some
changes.

Setting the font sets manually is a tricky business which requires
some non-trivial understanding of scripts, fonts, text-shaping
requirements and expectations, etc., and is quite hard to explain in a
comprehensive way that will cover enough use cases.  Therefore, we try
to have the defaults that work for the users, such that manual
customizations are reserved for rare cases and for people who know
what they are doing.  We don't want to confuse users with too many
technical explanations and details about font setup.

> CJK users would appreciate such instructions due to Han Unification[2].

What are the issues with font setup that Han Unification causes to
Emacs users?

Thanks.  Haven't pressed `F' (wide-reply) in Gnus before.  Still learning.

Emacs just crashed again after sending you the last email.
Here is the output from gdb

     https://codeberg.org/m0p/ublock-origin-mirror/raw/branch/main/gdb-1.txt

I would like to use

- NewComputerModernMono10 as default Monospace font,
- Tex Gyre Schola as both Serif and Sans Serif font,
- Fallback to STIX Two Math for missing mathematical symbols
- Fallback to Noto Serif CJK SC for missing 'han and 'cjk-misc glyphs

The interface looks like this when configured, but Emacs continues to
crash with this setup:

Namely, I am a Chinese speaker, of the Simpified variety on the
Mainland.  Emacs invariably chooses HK or JP glyphs by default, which I
do not understand. (I understand neither the behavior of Emacs nor the
glyphs.) I configured Simplified Chinese [SC] as fallback in fontconfig
and this works with firefox and terminal emulator.

Thanks.  It sounds like your Emacs has most of its debug info removed,
so the backtrace supplies only a partial information.  Is it possible
for you to rebuild Emacs with -g3 compiler switch and then try to
reproduce the problem?

Alternatively, can you build the current emacs-29 branch of the Emacs
Git repository, and see if the problem reproduces there?  A similar
bug was fixed after Emacs 29.1 was released, so it is possible that
these crashes are already fixed in Git.

Please explain why you want to use these and not the default fonts
Emacs uses on your platform.

Can you show screenshots of the same text as Emacs displays by
default, and as it should display according to your preferences?

Thanks.

Thanks, but debuginfo is absent from your backtrace.  Please compile
Emacs with CFLAGS set to `-Og -g3', and ack with a backtrace from that
build.

This boils down to the absence of support for stylistic sets within
Emacs.  I'd advise you to replace Noto Sans CJK with a CJK font family
that segregates stylistic variants of glyphs representing identical
characters into separate font files; such as PingFang SC, inter alia.

Will build from latest emacs-29 with -g3 and see if it still crashes.

I have configured gsettings/dconf to use aforementioned Monospace and
Proportional fonts, and that works fine in pure GTK Emacs in most cases.

But the important edge cases, such as the fallback to Simplified Chinese
font and AUCTeX prettify mathematical symbols with variable-pitch-mode
enabled, fails.

(The latter can be remedied by setting font-latex-math-face to something
else, but it still does not solve the fallback problem.)

This var-pitch fallback problem is also related to scaling.  I have
GDK_DPI_SCALE=2 set, and Monospaced font looks fine in HELLO, but
variable-pitch-mode causes several scripts to be displayed extremely
small.  You can see this here:

https://codeberg.org/m0p/ublock-origin-mirror/raw/branch/main/HELLO-proportional.png
https://codeberg.org/m0p/ublock-origin-mirror/raw/branch/main/HELLO-too-small.png

Besides, in my not so humble opinion, I think Emacs users should have
the freedom of choosing the preferred font without crashing Emacs,
regardless of defaults.  Font is a personal matter and one shouldn't be
dragged by others by the nose, as a Chinese idiom would say.

Sure.  Here I made a GIF from the screenshots, hope you can spot the
difference.

You do have the freedom, and Emacs gives users more freedom in
customizing fonts than most other GUI apps.  You just need to know
very well what you are doing to exercise that freedom, so we are
trying hard to make the need for that as small and rare as possible.

Thanks.  The question is: how can Emacs distinguish between these
fonts and decide that one of them is not suitable.  In general, Emacs
picks up the first font that matches the fontset's spec, so we need to
come up with two things: (a) the way for Emacs to distinguish between
these fonts, and (b) the way to encode the requirements for a "good"
font in our default fontset.  Then Emacs will be able to pick up the
correct font automatically.

In my experience, Emacs is certainly one of, if not the most effective
at customizing fonts, made even more impressive considering the fact
that everything is controlled by elisp.

Kudos to you for making a truly wonderful GUI possible!

Yes.  In a previous reply you mentioned that this configuration is
non-trivial, and indeed a perfect out-of-the-box experience is a noble
goal in itself.

Alas, some of us users would still try to customize the fonts with very
little understanding of the intricacies of Emacs internals.

I think this is not possible without the user explicitly specifying
which variant is needed.  In HTML this is done with language tags, such
as lang="zh-Hans", but this strategy only covers a minority of cases,
because

- the author of the HTML document has to specify this language tag
- the browser must understand this tag
- only applies to HTML documents

In most other cases, such as the user interface of an Android phone, the
default variant is chosen during language configuration.  If a non-CJK
language was chosen, such as en-US for American English (I do this), it
will behave in the same manner as Emacs.

"Good" is, in this case, defined by user.  One font suitable for
Mainland China users is not suitable for Taiwan, Hong Kong or Japan
users, and vice versa.  In other words, it is impossible for Emacs to
determine what variant does a given user prefer.

But there's good news.  I've rebuilt Emacs from latest commit (9 hours
ago) in the emacs-29 branch, with debug symbols enabled.  Fresh out of
the oven!  This was all made very simple and declarative thanks to the
Nix package manager:

https://codeberg.org/m0p/dotfiles/commit/e1fb4ffc4b4ce3a914adbd4c4a49863b2a48afeb

with the following init.el

https://codeberg.org/m0p/dotfiles/raw/commit/eec25a4ae443de78ea3d8ea3d94541060d7861d7/imports/not-nix-config-files/emacs-init.el

We will see if Emacs crashes again.  So far with (4 hours, 43 minutes, 3
seconds) uptime.

Emacs has something similar, it can access the language tags of the
font.  If the font specifies a language tag, we can configure the
default fontset in a way that in specific language-environments the
fonts with corresponding language tags are moved to the front of the
fontset.

Do the fonts that you want to use have such language tags?  If they
do, which language tags correspond to what language-environments in
Emacs?

These all are different language-environments in Emacs.  Type

  C-x RET l Chinese TAB

and you will see the Chinese language-environments that Emacs
supports.  When Emacs starts, the initial language-environment is
determined from the system locale, and the default fontset is arranged
accordingly.

So if certain language tags should be required from Chinese fonts in
specific Chinese language-environments, we can express that in our
default fontset, so that the need for configuring fonts manually is
avoided in more cases.

See above: is it really impossible?

How can I check this?  I tried `describe-font' on the font I wish to
use, the output is the following

name (opened by): -GOOG-Noto Serif CJK SC-medium-normal-normal-*-48-*-*-*-*=
-0-iso10646-1
       full name: Noto Serif CJK SC:pixelsize=3D48:foundry=3DGOOG:weight=3D=
medium:slant=3Dnormal:width=3Dnormal:scalable=3Dtrue
       file name: /.../share/fonts/opentype/noto-cjk/NotoSerifCJK-VF.otf.ttc

`fc-match' from fontconfig says

        familylang: "en"(s)
        stylelang: "en"(s)
        fullnamelang: "en"(s)
        lang: aa|ay|bg|bi|bin|br|ch|da|de|en|es|eu|fj|fo|fur

        li|ms|na|ng|pap-an|pap-aw|rn|rw|sc|sg|sn|su|za(s)
        namelang: "en"(s)

Does this mean that the font itself is broken?

I'm now convinced that this is indeed possible.  Thanks for the
detailed explanation, and apologies for not reading `(emacs)Language Enviro=
nments'
earlier.  But now I'm unsure whether this is a problem on the part of
the font, or something that could be fixed in Emacs.

The selection of Free-as-in-Freedom CJK fonts is already too
few, good ones even less, we could ill afford to lose more of them due
to trivial configuration problems.

In the meantime, I'm using the following snippet for fallback.  I've
removed all other configuration:
=09
	(defun my-configure-font (frame)
	  "Configure font given initial non-daemon FRAME.
	Intended for `after-make-frame-functions'."
	  ;; =E7=AE=80=E4=BD=93=E4=B8=AD=E6=96=87=E4=B8=8E=E6=A0=87=E7=82=B9=E3=80=
=82
	  (set-fontset-font t 'han (font-spec :family "Noto Serif CJK SC" :weight =
'medium))
	  (set-fontset-font t 'cjk-misc (font-spec :family "Noto Serif CJK SC" :we=
ight 'medium))
	  (remove-hook 'after-make-frame-functions #'my-configure-font))
=09
	(add-hook 'after-make-frame-functions #'my-configure-font)

Does this make any sense?

Try font-info instead, and look at the last, 13th, element of the
vector it returns.  The doc string of font-info describes what it can
tell you.

See above.

If the fonts you want to use indeed have the appropriate
language-system tags, then you can request those tags to be present
via set-fontest-font, by using the font-spec function to specify the
FONT-SPEC argument.  See the doc string of font-spec for how to
specify language-system tags.

The beauty of using font-spec is that you don't have to name the fonts
or their family names, only specify their properties and features, and
Emacs will find the right font(s) automatically (or at least it
should).

Yes, I think so.

It seems to me that the font declares support for all CJK scripts.

Thanks for the detailed suggestions, but I think I will not tweak that
any further at the moment, since I still do not have sufficient
knowledge for doing so.  Besides, I am already able to sit back and
enjoy variable pitch font in its full 4K-resolution, pure GTK on Wayland
glory.

By God, I was writing TeX in TUI Emacs for a whole year!  I didn't know
what was missing in my life.  Obligatory screenshot:

===================================================

Back to the original bug report:

Emacs has not crashed since the rebuild from latest commit in emacs-29
branch.  Previously Emacs server was crashing every few hours.

If there is no more crashes in the coming week, then I think this issue
can be closed.

And you are saying that this font is not appropriate for your
language-environment, contrary to what the font declares?  If so, you
could try telling Emacs to ignore than font, using face-ignored-fonts.

Thanks, so please come back and report in a week or so, or when it
does crash, whichever happens earlier.

Assuming you still have this session caught in GDB, please type at the
GDB prompt:

  (gdb) fr 8
  (gdb) p cache
  (gdb) p ftcrfont_info->metrics[row]

and post the results here.

By the way, I'm using Emacs server service, started by systemd.

When Emacs crashes, systemd logs the crash and gives me a
zstd-compressed coredump, located under /var/lib/systemd/coredump/.  All
outputs are obtained by running gdb on this coredump.  Don't know if
this matters, just stating a fact.

Po Lu, any idea what happened here?  ftcrfont_info->metrics is clearly
bogus, but how did it happen and why?  The argument FONT seems to be
valid.

How can I deduce the font name from the coredump?  And curiously this
crash only happens after using Emacs for sometime.  Viewing HELLO does
not crash Emacs out of the box.

Here is a full list of fonts on my machine, as produced by fc-list:

https://codeberg.org/m0p/ublock-origin-mirror/raw/branch/main/fc-list.txt

Alternatively, you can view the list of font packages installed, as
described by Nix:

https://codeberg.org/m0p/dotfiles/src/commit/460d5e9bb068368c6d38b546852f70d67730c65e/imports/desktop.nix

Line 217-247 and 403-408.

Worth noting is that I installed quite a few fonts from CTAN
(Comprehensive TeX Archive Network) into my system font path.

Is it possible to build Emacs with -fsanitize=address?  This is further
expounded upon in the GCC manual, and IME generally proves fruitful for
such spasmodic bugs, since you can run Emacs with address sanitization
enabled for extended periods of time as your "daily driver" (vis-a-vis
tools such as Valgrind, which incur a prohibitive performance penalty).

Yes, I've added this argument to CFLAGS and am rebuilding now.

Of note, I rebuilt pgtk Emacs without native compilation in order to
save time. Emacs has not yet crashed since that rebuild.  Don't know if
this might be related.

I'm currently starting Emacs server with systemd and hoping it would
crash sooner, but not when I'm writing assignments. ;-)

Update: the rebuild failed with the following output:

I think it is best to suppress memory-leak testing at this stage,
since the problems we are investigating cannot be caused by leaks (if
these leaks are real leaks at all).

I took the liberty of using a more descriptive email subject.

The build without Native Compilation also crashed, with mostly
identical causes.  This confirms the previous crashes are not one-off
events caused by M-x butterfly.

Here are the usual outputs from

The above backtrace seems to tell the following story:

  . Emacs loaded some package
  . loading the package triggered its processing (including loading of
    some other package)
  . eventually, as part of processing the loaded packages, Emacs
    called 'intern' (frame #74), which called check_obarray, which
    signaled a wrong-type-argument error (frame #71)
  . the error handling called the Lisp debugger
  . the debugger caused redisplay, which called cairo_show_glyphs,
    which caused an X error (frame #19)
  . the X error caused the X connection to close
  . Emacs then tried to shut down in an orderly fashion, which again
    triggered redisplay, which aborted (most probably because
    X-related data structures are invalid, due to the closed X
    connection)

I suspect that the error we tried to signal in frame #71 has something
to do with the recent changes in obarray handling, with which the
package that is being loaded here does not comply.  So I added Mattias
to the discussion.

I also see that we detect recursive invocations of redisplay too late,
so I have now fixed that on master.

As for the cause of this -- some problem in ftcrfont_draw -- maybe Po
Lu can suggest some ideas.  I guess we should try to understand what
kind of X error was caused here?

It looks like `intern` was called with a second argument that wasn't of =
a valid type (obarray or nonempty vector starting with 0) but that's as =
far as it goes, and doesn't indicate anything wrong in the obarray code.

We would need to catch it in the act with a debugger attached, and/or =
know what Lisp code is being executed.

Yes.  Please switch to the frame of the call to x_error_quitter, there
run:

  (gdb) p *event

I didn't trigger the error on purpose but by accident. A package used
obarray wrong (with nil instead of 0) which caused an error like this:
(wrong-type-argument obarrayp [nil nil nil nil nil nil nil nil nil nil
nil nil nil])

The error did not immediately cause a crash but some time after.

I have a gdb attached, If get a crash now I can send these outputs.

I'm not sure if this related but sometimes Emacs is stuck rendering
org-mode buffers till it receives SIGUSR2 or user input.
Requests such as emacsclient -nc don't reach Emacs until either of the
two above happens.
