bug#53497: 29.0.50; native-compile after restarting Emacs

[Arash Esbati]

Hi all,

when I delete all .eln files in the directory specified by
`comp-native-version-dir' and re-start Emacs, "standard" libraries, the
ones I require in my .emacs and installed via package are native
compiled (in my case 77 .eln files).  The issue:

1) When I do `M-x gnus RET', Gnus' libraries get compiled.
2) When I re-start Emacs instead and then do `M-x gnus RET', the
   libraries are not re-compiled.

Am I missing something?  This is Emacs dee029e19f compiled on Win10.

Best, Arash

I'm not sure I understand.  Do you expect the .eln files to be
re-compiled every time?  They aren't re-compiled unless the source files
change.

Sorry if I wasn't clear.  In case 2, Gnus libraries are not compiled at
all and I stick with 77 .eln files.  In case 1, I go up to more than 100
.eln files.

So you delete `comp-native-version-dir' between 1) and 2)?

No, that was step 0.  I did:

Case 1)
- Killed Emacs
- Deleted all files in `comp-native-version-dir' 
- Started Emacs
- Waited for 77 .eln to be compiled under `comp-native-version-dir'
- Started Gnus
- Watched Gnus libraries getting compiled

Case 2)
- Killed Emacs
- Deleted all files in `comp-native-version-dir'
- Started Emacs
- Waited for 77 .eln to be compiled under `comp-native-version-dir'
- Killed Emacs
- Started Emacs
- Started Gnus
- No compilation happens under `comp-native-version-dir'

What exactly do you mean by comp-native-version-dir? it is not a full
directory name, and there should be 2 such directories in any Emacs
installation: one under lib/emacs/ and another under
~/.emacs.d/eln-cache/.  Which one did you delete?

More importantly, why do you delete that directory? what is the
purpose of that, and what did you expect to happen as result?

Which of these 2 scenarios sounds problematic to you, and why?

How did you compile Emacs? did you use NATIVE_FULL_AOT=1 to natively
compile all the bundled *.el files, or did you use the default build
procedure that only natively compile only the preloaded *.el files?

If Emacs doesn't natively compile files it loads, it generally means
it cannot access the source *.el files, or that you load the *.el
files explicitly with the .el extension.

And I don't understand why the Gnus files need to be compiled each
time in the first place.  they aren't supposed to change, so they
should be natively compiled just once, when you first load them into
an Emacs session.

I deleted only the files in ~/.emacs.d/eln-cache/, to be more accurate,
~/.emacs.d/eln-cache/29.0.50-e0a1564a.  I didn't touch the directly
itself.

I had the impression that the deferred compilation doesn't work for me,
hence I deleted the files and played with the scenarios I described.

2) is problematic to me because Emacs doesn't compile libraries when I
use them after a re-start.  Gnus was only an example, it also doesn't
work when I load a .tex file with RefTeX enabled.  RefTeX libraries are
not compiled.  I basically stick with 77 .eln files forever.

I only pass '--with-native-compilation' to configure.

That's not my issue.  I don't want the files to be compiled again and
again (see below).

This is exactly my problem that files don't get compiled if I re-start
Emacs and then they are loaded (e.g. RefTeX).  It works only in the
first session when Emacs sees the empty ~/.emacs.d/eln-cache/ and starts
the machinery.

Doesn't happen here, so this is something specific to your system.

Does this happen if you start Emacs as "emacs -Q"?

I build Emacs with a small script like this, nothing specific (AFAICT):

time ( \
    git clean -fdx --exclude=ChangeLog
    ./autogen.sh &&             \
    CPPFLAGS='-DNDEBUG'         \

This is what I tried:

- I killed Emacs
- Moved all files in ~/.emacs.d/eln-cache/ to another directory
- Started "emacs -Q"
- No native compilation at all in ~/.emacs.d/eln-cache/, not a single
 .eln is generated

I guess this is not the expected behavior, right?

Why are you installing under a different prefix than used at configure
time?

What did you do after starting "emacs -Q"?  It isn't enough to start
Emacs, you need to cause it to load some package before it will start
compiling that package.

Btw, this could also be related to the problems I reported in

Yes I'm looking into that, I suspect this is not related tho.

In this case if Emacs was installed the different prefix might have
Emacs not able to find the original source file?  I'm just speculating
but if this is the case we should have a warning emitted.

Let's see.  Arash, could you please try reverting commits 6a79de5 and
9396b7d, install the Emacs you build without those two, and see if the
problem goes away?

I usually have multiple Emacs versions on my HD.  I install the latest
build in a temp directory, test it there and then move the entire layout
over the old version with emacs/bin directory in my $PATH.  I don't
fiddle with the files installed by Emacs.

I thought this is a documented way to install Emacs?[1]

Sorry, my bad :-(

I did "emacs -Q", opened a .tex file (without AUCTeX to get Emacs'
tex-mode) and did 'M-x reftex-mode RET' there.  Emacs doesn't
native-compile anything into ~/.emacs.d/eln-cache/.

Best, Arash

And if you say "C-h f reftex-mode RET", does Emacs report it as
"compiled" or "natively compiled"?

I checked out 1476b0d7a6 (which was the last commit before the two
above) and built Emacs twice: Once with my original recipe (pass prefix
to make install) and once passing --prefix to configure.  No avail with
both versions.

=> "compiled"

reftex-mode is an autoloaded interactive compiled Lisp function in
‘reftex.el’.

OK, thanks.

So I think the only way to make progress here is to run Emacs under
GDB, with a breakpoint in maybe_defer_native_compilation, and if and
when it breaks, see what goes on there.  In general, this breakpoint
should break as soon as you invoke some command that loads a .elc file
for which there's no corresponding .eln file.

I hope your Emacs is not stripped of debugging symbols; if it is,
please rebuild and install without stripping and with -g3 switch, and
run the resulting executable under GDB as described above.

Thanks for the guidance.  I did that all and stared for some times at
it.  Since it doesn't emit an error and I'm not really familiar with the
code, I think I have to spend more time on this exercise.

I suggest I close this report for now and dig further, I can re-open
once I have something new.

OK for you?  Thanks again to you all.

You mean, the breakpoint in maybe_defer_native_compilation never
breaks?  That in itself is probably a sign of some problem.

There's no need to close it right away, unless you can no longer
reproduce the issue.  I'd prefer to close when we either understand
the reasons or the problem goes away by itself and becomes
unreproducible.

This is what I do and see:

'Thread 1 hit Breakpoint 1' starts when I try to 'C-x C-f' a .tex file
in Emacs.  And then I can use n, s within the debugger.  But I don't get
any error and such.  Does this make sense to you?  I'm not really
familiar with GDB.

Fine with me.  Currently, I can reproduce it reliably.

Step through the code of maybe_defer_native_compilation with the 'n'
command, and see if it calls native--compile-async in this fragment:

  /* This is so deferred compilation is able to compile comp
     dependencies breaking circularity.  */
  if (!NILP (Ffeaturep (Qcomp, Qnil)))
    {
      /* Comp already loaded.  */
      if (!NILP (delayed_sources))
	{
	  CALLN (Ffuncall, intern_c_string ("native--compile-async"),
		 delayed_sources, Qnil, Qlate);
	  delayed_sources = Qnil;
	}
      Fputhash (function_name, definition, Vcomp_deferred_pending_h);
      CALLN (Ffuncall, intern_c_string ("native--compile-async"),
	     src, Qnil, Qlate);
    }

If the code exits the function before getting to this place, try to
figure out why.  It could fail to load libgccjit DLL, here:

  if (!load_gccjit_if_necessary (false))
    return;

Or it could exit due to one of the following conditions:

  if (!native_comp_deferred_compilation
      || noninteractive
      || !NILP (Vpurify_flag)
      || !COMPILEDP (definition)
      || !STRINGP (Vload_true_file_name)
      || !suffix_p (Vload_true_file_name, ".elc")
      || !NILP (Fgethash (Vload_true_file_name, V_comp_no_native_file_h, Qnil)))
    return;

Or it could exit because it doesn't find the Lisp source file:

  Lisp_Object src =
    concat2 (CALL1I (file-name-sans-extension, Vload_true_file_name),
	     build_pure_c_string (".el"));
  if (NILP (Ffile_exists_p (src)))
    {
      src = concat2 (src, build_pure_c_string (".gz"));
      if (NILP (Ffile_exists_p (src)))
	return;
    }

Does one of these early returns indeed happen?

If not, i.e. if the code indeed calls native--compile-async, then you
should see a subprocess being started: native--compile-async calls
comp-run-async-workers, which calls make-process.  The code is in
comp.el.  If the subprocess is started, then JIT native-compilation
does work, and the question is what happens with the produced *.eln
files.

This part looks like this for me:

  /* This is so deferred compilation is able to compile comp
     dependencies breaking circularity.  */
  if (comp__loadable)
    {
      /* Startup is done, comp is usable.  */
      Frequire (Qcomp, Qnil, Qnil);
      Fputhash (function_name, definition, Vcomp_deferred_pending_h);
      CALLN (Ffuncall, intern_c_string ("native--compile-async"),
	     src, Qnil, Qlate);
    }
  else
    Vcomp__delayed_sources = Fcons (src, Vcomp__delayed_sources);

> Does one of these early returns indeed happen?

No, early returns don't happen, but if (comp__loadable) goes into the
else part.  This is the part in GDB with Emacs b373c8ad71:

Andrea, can you explain how this is supposed to work?  comp--loadable
is set in startup.el, provided that comp--delayed-sources is non-nil,
but which code is supposed to put something into comp--delayed-sources
by the time we call startup--honor-delayed-native-compilations during
startup?

IOW, I'm not sure I understand how this is supposed to work.

What is the value of Vcomp__delayed_sources?  You can display it like
this:

  (gdb) source /path/to/emacs/src/.gdbinit
  (gdb) pp Vcomp__delayed_sources

This is a build with -g3?

Strange, it sounds like GDB cannot access macros,which -g3 should
allow.

And it stays nil afterwards?  Or does it grow to include all the files
you expect to be natively-compiled as part of the session?  Is
maybe_defer_native_compilation called more than just once?  If so,
what is the value of Vcomp__delayed_sources for those other calls?

This is Windows after all ;-)

No, it doesn't (see below)

maybe_defer_native_compilation is called more than once.  This is the
result of multiple runs.  What remains is that the part to
"native--compile-async" is never called.

Below, [...] is always the repetition between
if (!load_gccjit_if_necessary (false))
and
if (comp__loadable)
which I've deleted.

No, it works for me on Windows, that's why I'm surprised.

OK, so the list of deferred compilations grows, but no file is
actually being compiled for some reason.

Let's wait for Andrea to describe how it is supposed to work, and take
it from there.

Before `comp--loadable' becomes true (read the native compiler is not
loadable) each time we enter in 'maybe_defer_native_compilation' we
accumulate the compilation units we want to compile in
`comp--delayed-sources'.

When we finally call `startup--honor-delayed-native-compilations' we
check if something is pending in `comp--delayed-sources' and if this is
the case we load the native compiler and we compile what's pending.

Unless I'm wrong the problem I see here is that if
`comp--delayed-sources' is empty we never set `comp--loadable' to t.
I'll be testing a patch today and report.

Yes, I understood that much.  What I didn't understand was how would
comp--delayed-sources become non-empty during startup, if none of the
files loaded during startup need to be native-compiled.

> Unless I'm wrong the problem I see here is that if

Yes, I think so.

Hi Eli,

I pushed d0aac84b2a as it seems to work for me here.

Thanks.  But is it right to set comp--loadable regardless of whether
native-comp-available-p returns non-nil?

In principle I'd say so, otherwhise we'll keep accumulating filenames in
`comp--delayed-sources' for all the session.

If we don't want to have errors raised by the deferred compilation when
an Emacs with native comp support is running without the native compiler
available I think we should guard against `native-comp-available-p'
inside 'maybe_defer_native_compilation'.  WDYT?

Thanks

Thanks for looking into this.  I built Emacs (0991e8686cd) and started
with "-Q".  Doing C-x C-f trying to open a .tex file says:

  require: Recursive ‘require’ for feature ‘comp’

in the minibuffer and the file doesn't get loaded.

Please run Emacs under GDB, put a breakpoint in Frequire, here:

      if (nesting > 3)
	error ("Recursive `require' for feature `%s'",  <<<<<<<<<<<<<<<<<<
	       SDATA (SYMBOL_NAME (feature)));

repeat the above sequence, and when the breakpoint breaks, show the
backtrace and xbacktrace.  (For "xbacktrace" you will need to "source
.gdbinit", as you did before.)

Please find attached the results.  Took me some iterations in GDB to get
to the error.

As a note, I started the session directly in emacs/src tree with
'gdb ./emacs'.  But that shouldn't make a difference, I can trigger the
error also from an installed version with 'make install'.

Best, Arash

Hi Arash,

apologies for not having time to re-read the whole thread.  What's the
current minimal reproducer we have to obtain this?

Thanks!

Hi Andrea,

No problem.  I did:

- git pull (to 0991e8686c)
- git clean -fdx --exclude=ChangeLog
- ./autogen.sh
- ./configure --prefix=/z/emacs-install-native-comp \
              --with-native-compilation \
              --without-compress-install \
              --without-mailutils \
              --without-pop \
              CFLAGS='-O0 -g3
- make -j8 && make install
- cd /z/emacs-install-native-comp/bin
- ./emacs -Q
- In Emacs, C-x C-f path/to/minimal.tex (which is just an arbitatry
  minimal LaTeX file and attached)

To double check, I also started Emacs after compilation from src/ in the
git repo, same result.

This is on Win10 with gcc 11.2.0 (Msys2). Please let me know if I've
left out something important.

Best, Arash

Can you please go to each frame that shows a call to Fload, like this:

> #5  0x00007ff6237c5cc1 in Fload (file=XIL(0x23ec05077ac), noerror=XIL(0),
>     nomessage=XIL(0x30), nosuffix=XIL(0), must_suffix=XIL(0x30)) at lread.c:1588

and show the value of its 1st argument, called 'file'?  Like this:

 (gdb) fr 5
 (gdb) pp file

and similarly with every other frame that calls Fload, top to bottom?
The frame number is that #5 part that's at the beginning of each
backtrace line.

Thanks, I think I see what's going on.  I've an (hopefully) better
patch, I'll test it better after dinner and report.

So I could not reproduce the issue (probably because of a different
configuration), but I think (hope) 536a57b72c might help with the
problem.

Arash could you test if it works for you?

Thanks for your time.

I did with version 84d4a34919.  I built Emacs as described here[1] and
this is how it works:

1. emacs -Q

I start with "emacs -Q" and "C-x C-f" a .tex file.  Emacs opens the file
and native-compiles:

Compiling z:/pathto/emacs/share/emacs/29.0.50/lisp/emacs-lisp/cl-lib.el...

Compiling z:/pathto/emacs/share/emacs/29.0.50/lisp/textmodes/tex-mode.el...
Compilation finished.

I close Emacs, re-start with "emacs -Q" and it does:

Compilation finished.
Compiling d:/arash/Dev/Emacs/emacs-install-native-comp/share/emacs/29.0.50/lisp/calendar/time-date.el...
Compilation finished.

No further native-compiling after further re-starts.

2. emacs &

Emacs native-compiles a series of files upon start, I skipped opening my
.tex file and re-started Emacs, and it native-compiles the files again,
and this cycle goes on and on.  I'm attaching the results further below.

So I think there is still something going wrong.  My .emacs is actually
not complicated and the only `native-compile' relevant bit is:

    (when (featurep 'native-compile)
      (setq native-comp-async-report-warnings-errors 'silent))

> Thanks for your time.

Sure, thanks to you and Eli for yours.

Best, Arash

I built Emacs with the new patch provided by Andrea, see my other
message.  Please let me know if I can provide any input.

Andrea, I see something similar as well in "emacs -Q -nw" on
GNU/Linux: subr-x.el and gv.el are natively-compiled each time I
restart Emacs, even though the previously-compiled *.eln files with

the -nw switch is needed to trigger this, but other than that, I need

I can see it now with "emacs -Q -nw" thanks, I'll look into that.

Okay, I think this is an unrelated issue to the circular dependency one
(that appears to be solved).

I see that when subr-x is required (see following stacktrace)...

"require" (0xffff9ef8)
"byte-code" (0xffffa3e0)
"byte-compile-eval" (0xffffa678)
0xc53bd8 PVEC_COMPILED

0xb6da60 PVEC_COMPILED
"macroexpand" (0xffffb5a8)
"macroexp-macroexpand" (0xffffb828)
"macroexp--expand-all" (0xffffbbb8)
"macroexp--all-forms" (0xffffbe28)
"macroexp--expand-all" (0xffffc148)
"macroexpand-all" (0xffffc2a8)
"byte-compile-preprocess" (0xffffc428)
0xb82c50 PVEC_SUBR
"byte-compile" (0xffffc7d8)
"cl--generic-get-dispatcher" (0xffffc9a8)
"cl--generic-make-next-function" (0xffffcb28)

"tty-find-type" (0xffffdb28)
"tty-run-terminal-initialization" (0xffffdcd8)
"command-line" (0xffffde90)
"normal-top-level" (0xffffdf20)

...we do not find the coprresponding .eln even if present because
'Vnative_comp_eln_load_path' has still to be updated with the eln-cache
directory of the user.  In my case the content there is only:

("/home/akrl/emacs2/src/../native-lisp/")

Given the .eln is not found we native compile it again.

I suspect this is related to the recent changes of where
`native-comp-eln-load-path' is set, maybe Lars can comment.

Note that I'm on bf695b937e so I should have the very latest changes.

Best Regards

That's certainly possible -- it's really difficult to trace the logic
here in the startup code.

Does moving the setting earlier again fix the problem?

Yeah our startup has a lot of hidden dependecies.

If you refer to bf695b937e that's not sufficient, the test was done with
it installed.  I haven't checked if bf695b937e has restored the state of
say one week ago (in terms of where we set native-comp-eln-load-path) or
not.

But yeah the bottom line is that indeed we need to have
native-comp-eln-load-path set before we expect the native compiler
machinery to work.

I don't think we can move the initialization of
native-comp-eln-load-path to after the call to command-line, because
Lisp packages can be loaded as early as while loading early-init.el.
So we need to initialize native-comp-eln-load-path as soon as we have
user-emacs-directory, and then amend the value after calling
command-line.

I installed a fix along these lines which seems to be working for me.
Arash, please see if your problems are solved now.

Yes, they are solved now.  Many thanks to you all for taking your time!

I'll close this report.

Best, Arash
