bug#69431: 30.0.50; Strange fontificaion behavior

[OGAWA Hirofumi]

I met the strange font-lock behavior,

# this doesn't work
    $ echo '* Foo' > a.org
    $ emacs -Q a.org

The above opens "a.org" as org-mode, but current emacs doesn't
fontificate the buffer properly for this.

But while reproducing this behavior, I noticed the following works as
expected.

# this works
    $ echo '* Foo' > a.org
    $ emacs -Q --eval "(provide 'dbus)" a.org

Thanks.

I cannot reproduce this with today's master branch.  I see "* Foo"
fontified with org-level-1 face.

Maybe this is platform-dependent?

I can reproduce using the latest master (with make bootstrap), using the
same steps. I cannot reproduce when changing the load path to Org git
folder ( main, bugfix branches, and Org 9.6.15 tag which should be the
same with Emacs built-in version).

I don't want to bootstrap for this, but I removed all *.elc files from
the lisp/org/ directory and rebuilt, and I still cannot reproduce.

So maybe the problem is already solved somehow?

I found a bit more about this. If build with --native-compilation=no, I
can't reproduce, and at least --native-compilation=aot can reproduce.

Thanks.

... or it has something to do with loading built-in Org mode.
when I do
1. emacs -Q
2. C-x C-f /tmp/a.org
I do not see fontification.

when I do
1. emacs -Q
2. M-: (require 'org)
3. C-x C-f /tmp/a.org
I see fontification...

and when I wait long enough for native compilation to finish, I can see
fontification without loading org.el.

Not sure if it tells anything useful.

Since this seems to be somehow related to native compilation, I'm
adding Andrea to the discussion, in the hope that he could suggest
some ideas.

Hi Eli,

thanks.

I suggest to disable `native-comp-jit-compilation' in the .emacs, clean
the eln-cache and run Emacs ruling out the native compiler, this in
order to understand why without '(require 'org)' fontification does not
happen.

My guess is it's because of some quirk in the code and, when the native
compiler reloads the native compiled version of the code somehow this is
fixed, at least at a first glance I'd guess is not native compiler
related (last famous words...).

Thanks

  Andrea

    $ echo '* Foo' > a.org
    $ emacs -Q --eval '(setq native-comp-jit-compilation nil)' a.org

This seems make fontification work (with or without clean eln-cache).

Doing the following makes fontification happen
./src/emacs -Q --eval '(setq native-comp-jit-compilation nil)' /tmp/a.org
while just
./src/emacs -Q /tmp/a.org
has no fontification.

Mmmhhh, could you dump load-history for the two cases?

Would be cool to have a Lisp backtrace at the moment of the SIGEGV to
understand what we are trying to load and in which order before we stack
overflow.

Another idea would be to apply something like the following to
Frequire, run a make, and run again the reproducer to understand what's
going on.

I'd do the investigation myself but my dev machine went KO yesterday and

It does sound like it.

Is the it normal that gdb tell me:
warning: Corrupted shared library list: 0x1701f5b0 != 0x19cf8b60

When running Emacs in GDB?
I have the same error with my last known good version.

I've attach the current log I have and try further.

bug#69431: 30.0.50; Strange fontificaion behavior

[Björn Bidar via Bug reports for GNU Emacs, the Swiss army knife of text editors]

One issue with the problem I noticed with erros I receive that they all
happen after building emacs with make bootstrap.
Even in the "good" revisions.

I think so, I've seen this in the past and never bothered too much (but
I'm not a gdb guru so I can't give you a good explanation).

I verified if anything is wrong in my setup but reverting to the last
known good ref c59c8db98a1d031a20ec7850978653657e394baa made everything
work again.
One thing I noticed when updating my package is that building without
make bootstrap was impossible. Only after make bootstrap the build did
succeed again.

Good look. Thanks for your work.

I found the culprit of the problem: it's load-theme.
The only theme's could trigger the bugs so far for me where modus
themes.

Hi Björn,

thanks.  Sorry I had to pause on this as I'm focused on fixing
everything I've broke recently on master 😅.  I'll be back on looking at

On 415604c7a77 (current master) I'm having trouble reproducing this.
Both with the eln cache empty both with it already warmed.

Is this just local on my machine or the bug vanished? 🤔

Okay I can reproduce it using Emacs with GUI and not on terminal.

Okay I've spent some time investigating, on my setup I can reproduce
this on GUI *only* when the eln-cache is empty with the suggested $ emacs -Q foo.org

I can't reproduce configuring with --with-native-compilation=aot

I can't reproduce with $ emacs -Q -eval "(setq native-comp-jit-compilation nil)" foo.org

These observations would suggest is native compilation related.

I can't see any SIGEGV in gdb in all of these tests.

Also as Ihor suggested (thanks!) reverting cf11fdfd8e46 makes issue not
reproducible here, but I still have to understand the reason (maybe some
circular dependency??).

Meanwhile Björn could you try reverting cf11fdfd8e46 and report if fixes
for you as well?

Thanks

The bug in my last message only seem happen sometimes.
Now Emacs did not built without bootstrap as before
it failed with: error ("Invalid byte opcode: op=0, ptr=0")

during the built.

After continuing to built with make bootstrap Emacs built fine but the same bug occured that
I originally mentioned happened again.

bug#69431: 30.0.50; Strange fontificaion behavior

[Björn Bidar via Bug reports for GNU Emacs, the Swiss army knife of text editors]

The bug in my last message only seem happen sometimes.
Now Emacs did not built without bootstrap as before
it failed with: error ("Invalid byte opcode: op=0, ptr=0")
imagemagick-register-types()
during the built.

After continuing to built with make bootstrap Emacs built fine but the same bug occured that
I originally mentioned happened again.

I'm trying to progress on this but I've difficult time at getting a grip
on this bug.  One of the reason why is that on my reproducer Emacs
doesn't crash nor complain, the other reason is that I'm not really into
our fontification.  I'll keep on looking into it but I'd appretiate any
hint like: what should be happening to fontify the buffer that is not
actually happening here?  With such info I could try investingating the
issue from there comparing with the working case.

Thanks in advance!

Maybe Stefan (CC'ed) could help in that matter?

Hmm... here, after

    rm -rf ~/.emacs.d/eln-cache
    src/emacs -Q --eval '(setq debug-on-error t)' a.org

I get a buffer with no fontification, that claims to be in Org mode but
whose `font-lock-keywords` is just (t nil), which explains the lack
of fontification.

And if I wait long enough for all the org files to be native-compiled,

    src/emacs -Q --eval '(setq debug-on-error t)' a.org

opens up a buffer with the usual fontification.

Where `font-lock-keywords` are supposed to be set?

`font-lock-keywords` is normally set from `font-lock-defaults` (which is
set by the major-mode) by `font-lock-set-defaults` when `font-lock-mode`
is enabled (which usually happens soon after enabling the major mode,
via `after-change-major-mode-hook`).

Sorry didn't had much time to progress on this.

I see `font-lock-mode` and `font-lock-set-defaults` are called when
opening an org file here on my reproducer.

Also I see `font-lock-set-defaults` is actually set! So I'm wondering
why afterwards the value changes for my test.org.

Will look into it more hopefully tomorrow.

So from what I see in the non working example 'font-lock-keywords' is
cleared at the end of 'org-set-font-lock-defaults' which does
'(kill-local-variable 'font-lock-keywords)'.

Now why this is not happening in the working example I'm not sure ATM,
('org-set-font-lock-defaults' is not even called there AFAICS).

Maybe org maintainers can comment if this is expected or not, or explain
meanwhile the mechanism so debug will be easier.

Thanks!

I am pretty sure that it does get called, but before your variable
watcher becomes active.

I suspect that font-lock is dumped to Emacs.
Maybe related to bug#66741.

bug#69431: 30.0.50; Strange fontificaion behavior

[Björn Bidar via Bug reports for GNU Emacs, the Swiss army knife of text editors]

I want to add the bug happens for me to where I don't load an org-mode
file but have org-mode as a mode for the scratch buffer plus
modus-theme-vivendi as theme.

I tried to trigger the bug with just emacs -Q plus modus-theme-vivendi
but that wasn't enough.
I assume the bug isn't triggered before a certain amount of memory has
been used.

bug#69431: 30.0.50; Strange fontificaion behavior

[Andrea Corallo]

Okay after "some" debugging my theory is that it is problematic to setup
the fontification while the setup of another fontification is active on
the stack.

This is what is happening here because while we are setting up
fontification for 'test.org' native compilation activated
'emacs-lisp-compilation-mode' on the '*Async-native-compile-log*'
buffer.

If I remove the invocations of 'emacs-lisp-compilation-mode' from
'comp-run-async-workers' my org file gets fontified correctly.

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

Why are we setting 'font-lock-keywords' on test.org if the last major
mode activation we have on the stack is for
'emacs-lisp-compilation-mode'?  IOW why the current buffer is test.org
if 'emacs-lisp-compilation-mode' is called wrapped by
'with-current-buffer' on '*Async-native-compile-log*'?

Also is the value of 'font-lock-keywords' we are setting on test.org the
expected one or are we mixing up things?

Thanks

IMHO, it looks like bug#58888 - global font-lock-mode is enabled in the
middle of major mode initialization and messes things up.

Finally we start to see the light :)

What I see is that 'global-font-lock-mode-enable-in-buffers' when
executed iterates over 'global-font-lock-mode-buffers' to do things.
AFAIS when two major modes are being activated at the same time on the
stack it mess things up.

With the following patch installed on my reproducer both the org buffer
and both '*Async-native-compile-log*' are fontified correctly.

I'd like to have Stefan opinion if this is okay or we have a better way
to fix this.  If this approach is okay I'll install it with some
commenting.

That's infinite recursion, a different problem.

Is there already a bug for this issue or should I open a new one?

It depends, I think.  What is the recipe for what you see?

It is some kind of recursive call:

  face-attribute->face-attribute-merged-with->face_attribute->...

Looks like a separate problem to me.  It is important to understand
what face causes this, and what is that face's spec.

Also, please make a point of loading the src/.gdbinit file from the
Emacs source tree before running Emacs under GDB, so that the
backtrace includes also the Lisp backtrace, and shows Lisp objects in
human-readable format, for easier reading.

Both backtraces are almost identical, and in both the problem seems to
be triggered by loading and enabling a theme.  So I don't think I
understand what you say here about "enough packages" -- I don't
suppose all of the packages you load are themes, are they?  IOW, can
you show a backtrace from a crash that is not caused by loading a
theme?  E.g., what happens if you remove all theme loading and related
stuff from your init files?

The backtrace was with src/.gdbinit loaded however the lisp wasn't
included the backtace I suspect it is because:
Cannot access memory at address 0x7fffff66ff7f

What do you mean by related?
If I don't load a theme Emacs doesn't crash but if I start Emacs with -Q
and load the theme it's not enough to crash Emacs that's why I mean by
enough packages essentially.

Eventually I isolated the exact problem what caused the bug:
1. (setq max-lisp-eval-depth 32768)
2. load-theme modus-vivendi (any modus theme works as a trigger)

With the Emacs ref c59c8db98a1d031a20ec7850978653657e394baa  
this Emacs doesn't crash with the same settings.

Are you saying that an init file with only those two lines causes the
crash on your system?

OK, but lots of water under the bridge since then...

Of course but it's the last ref I know the bug does not trigger with
these settings.

I tried the following recipe on latest master but can't reproduce.

BTW this is different bug from the one being treated here, ideally would
be better to have a dedicated bug.

Thanks.  Can someone else reproduce with the latest master branch?

What do you mean with "the bug is still present"?  Which are the actions
that produced the following backtrace?

The patch seems to work here (bootstrap from scratch + some normal use).

It's an ugly workaround, so it would need some comment.

Yes, it's a problem in `easy-mmode.el`.  I think the patch below should
fix it (it'll need recompiling those files which define globalized
minor modes before it gets effective).

Actually, nowadays modes that don't use `run-mode-hooks` should be
vanishingly rare and I think we could "drop support" for them, which
would significantly simplify that macro.
