I'm not quite sure that it's this patch, but the some electric tests
started failing today with the following backtrace:

Yes, sorry, it's that patch indeed.  It's a rather serious bug which
might have left C Mode unusable.  I'll fix it right now.

Thanks; that fixed two of the failing tests.  There's still one
remaining, though:

1 unexpected results:

Yes, I thought it best to fix the first bug first.  In C Mode, it threw
an error merely by typing into a string.

I've just comitted a fix for the other bug, which was more complicated.

Thanks; I can confirm that the test failure disappeared here, too.

On hydra, electric tests began timing out with c4d34d, and continue to
do so through at least 9c5dc3c.

Huh.

  ELC      lisp/electric-tests.elc
  GEN      lisp/electric-tests.log
building of '/nix/store/g7mnplyk8lfyxlv9ggcy25msgrwp5vz9-emacs-coverage-unknown' timed out after 7200 seconds of silence

I saw the same thing -- but only on one machine, and only with "make
check-maybe".  And it went away there after doing a full "make -j16" in
the test directory, so I thought it was just a transient thing...

Let's see...

Yup, the following seems to hang reliably for me:

touch lisp/electric.el; make check-maybe

This is on Debian/bullseye, if that makes a difference.

For what it's worth, I can't reproduce it on Gentoo.  The check-maybe
just completes normally.

And I can't reproduce it either now.  Yesterday, it was totally
reproducible on two different machines, but not today.  :-/

It still seems to be timing out on Hydra.  Perhaps it's something
weirdly timing related?

It's hanged several times for me locally on Debian Testing after a
bootstrap, FWIW.  Haven't yet had time to investigate further.

I'm able to reproduce the hang in the test
electric-layout-plainer-c-mode-use-c-style with:

  make TEST_LOAD_EL=no test/electric-tests

The hang seems to be happening in c-beginning-of-macro, from the second
call to c-point-syntax in electric-layout-for-c-style-du-jour.

HTH,

I'm not able to reproduce this here on my two Debian machines -- but I
did see one of these hangs yesterday.  So it's a real heisenhang.

Right now it's happening reliably on my Debian machine.  Should it be
tagged as unstable or unconditionally skipped until it's further
debugged?

I can't reproduce the hang with your recipe, either.  For what it's
worth, I'm running a pure 64-bit AMD-Ryzen Gentoo Gnu/Linux system, with
the following Emacs configuration:

 'configure --with-gif=no --with-tiff=no --with-gpm
 --with-native-compilation'

To my above configuration, I added --enable-checking=structs, and with
that I can reproduce the hang using your recipe above.

But with TEST_LOAD_EL=yes, the test runs to completion.  This suggests
there is some bug in the compilation of some .el file -
electric-test.el, perhaps?  Are we talking about a .elc or a .eln here?

You say c-beginning-of-macro seems to be hanging.  js.el advises
c-beginning-of-macro (along with two other CC Mode functions), and this
may have something to do with it.

At least, if I comment out all the lines in test/lisp/electric-tests.el
with "js" in them (apart from the first occurrence, where one just
comments out "js-mode" from the line), then the hang doesn't happen.

Something to think about.

Huh, I wonder how that could possibly be making a difference here.

I haven't configured this Emacs with native compilation (I've done that
in a separate Git worktree), so this shouldn't have anything to do with
.eln files.

Yes, that's as deep as I got with print debugging before calling it a
night.

Indeed, if I comment out all the js-mode-related
define-electric-pair-test forms, as well as the js-mode inside
define-electric-pair-test, then

  make TEST_LOAD_EL=no test/electric-tests

no longer hangs, but electric-pair-open-extra-newline fails.

Tonight, I tried the following approach instead (in an unedited source
tree):

0. C-x p c make TEST_LOAD_EL=no test/electric-tests RET
1. M-! pkill -SIGUSR2 -f ert-run-tests RET

I repeated this a few times, and the *emacs-compilation* buffer reliably
contained the same backtrace:

> HTH,

That helps a great deal, thanks!

The problem is a bug in c-point-syntax.  There, there is
  (i) an invocation of c-save-buffer-state, which binds buffer-undo-list
  to t, followed by
  (ii) an invocation of c-tentative-buffer-changes, which pushes nil onto
  buffer-undo-list (simulating an undo group) giving (nil t).
  (iii) A { is typed into the buffer, giving buffer-undo-list now as
  something like ((5128 . 5129) nil t).
At this point garbage collection occurs.  This strips the tail of
buffer-undo-list, leaving ((5128 . 5129)).
  (iv) In c-tnt-chng-cleanup, primitive-undo is repeated infinitely,
  since buffer-undo-list will never become the expected value (nil t).

The problem would appear to be the invalid value ((5128 . 5129) nil t) in
buffer-undo-list.

I'll see what I can do about this tonight.

I've just committed a patch to master which I think fixes the problem.

Thanks especially to Basil for exceptionally helpful debugging info.

Thanks!  That indeed fixes the hang here.

If it stops the hangs from happening on Hydra as well, then the relevant
electric-tests will no longer need to be skipped there.

I see only one minor issue with the patch: it introduces a use of the
macro c-benign-error before its definition, which gives rise to a
byte-compiler warning.  I would have moved the macro's definition
myself, but I see the file is organised in a particular way, so I leave
that to you.

Thanks,

Thanks, but this triggers a byte-compilation warning:

  In c-benign-error:
  progmodes/cc-defs.el:1046:11: Warning: macro `c-benign-error' defined too late

Sorry about that.  I completely missed that warning message (which
perhaps ought to be an error, since it compiles a function call instead
of expanding the macro).

I've moved the macro to earlier on in the file.  No big deal.  I've
committed the change, and it should be OK now.

Sorry, I just missed that warning.  I've committed a correction now, so
things should now be OK.

The bug in fact had nothing to do with multi-line strings, and had been
in place for many years.  Only a garbage collection in the "wrong" place
triggered it.
