I think using the SetHandleInformation here should be appropriate.
The implementation of _fdopen in ucrt is similar to Wine, it starts
looking from ` _IOB_ENTRIES` (== 3) stream. Here is the extracted source
code https://github.com/huangqinjin/ucrt/blob/master/stdio/stream.cpp#L12

So, once we close the `stdin/out/err`, there's noone who get assigned
back to those streams, and then the final close in `sys_dep.c` will fail
for UCRT.

I have tested with my own UCRT64 build of Emacs at
https://github.com/kiennq/emacs-build/releases/tag/v31.276.20240805.2332f50,
With the patch of
https://github.com/kiennq/emacs-build/edit/main/patches/0001-init_winntproc-Use-SetHandleInformation-to-set-NOINH.patch

The SetHandleInformation returns no error even without streams being
closed.

Thanks, noted.

What we need next is (a) a clean patch, and (b) thorough testing that
the standard handles are indeed not inherited by sub-processes of
Emacs when the patch is applied.

What should be the testing for (b)?
One thing I noticed when I used a version with broken stdout is that the
async
compilation (native or via async package) doesn't work properly. Those
errors
don't show up anymore for the patch of using SetHandleInformation.

I have been using the UCRT version for a while and notice nothing has gone
wrong so far even with the `native-comp-jit-compilation'. It would be great
if
someone can share how I can do further testing on this.

I'm not sure I understand what you are asking.  Are you asking how to
test that the standard handles aren't inherited by subprocesses?

I'm not talking about testing the broken build: it's known to be
broken.  I'm talking about testing the fixed build: the fragile dance
we do with the standard streams is there for a reason, and we need to
make sure the modified code does the job as well.

Btw, I still don't think I've seen the patch you are want to test, so
I don't even know if it's clean and correct by itself.

I can check that the SetHandleInformation is returning TRUE so the handles
shouldn't be inherited already.  However, is there any Emacs feature
that will be
broken if the handles are inherited?  I would like to test that to make sure the
E2E flow is still working.

This is not about some Emacs feature, or at least not only about that.
This is about having Emacs on Windows behave the same as Emacs on
Posix systems, wrt inheriting handles to child sub-processes.  We want
this to be done so that anyone who writes a Lisp program that launches
sub-processes could be certain they will behave the same wrt
inheritance of standard handles, on all supported systems.

To test that, one would need to demonstrate that the parent Emacs
process can do something with its standard handles without affecting
the same handles of the child process.  For example, moving the file
pointer in one process doesn't move it in the other.  As another
example, if Emacs's standard output is redirected to a file, and
writing to stdout in the child process writes to that same file, then
the standard output handle _was_ inherited.  Yet another possibility
is to use a tool such as ProcessExplorer to show the target of each
handle, in both parent Emacs and its child sub-process, and verify the
target is different.

This is not what I think we need.  First, there's no need to change
anything in the MSVCRT build, because AFAIK the current code "just
works" in such a build, both in 32-bit builds and in 64-bit builds.
The problem happens only in UCRT builds.

Second, UCRT builds are only supported on versions of Windows where
SetHandleInformation is always available; on older Windows systems,
the UCRT build will refuse to run, because UCRT is not available.

So what I think is needed is a compile-time condition that makes the
UCRT build use SetHandleInformation instead of the
DuplicateHandle/fclose/_fdopen dance, and leaves the existing code
intact in non-UCRT builds.  I think "#ifdef _UCRT" is such a
condition, but I'm not 100% sure.

Okay, put a new patch.
By the way, the code of using `pfn_SetHandleInformation` has been using by
`init_winsock` as well for the same purpose of making the handle not
inheritable.  So I think we should be pretty safe with this change.

I'm not sure how to redirect Emacs output in Windows.  And using
ProcExp64, I can
confirm that the standard handles (\Device\ConDrv\Input ...) is not refereed by
its child processes.  Let me know if you want me test other scenarios.

Thanks, this patch LGTM.  Given sufficient testing (see below), I
think we can install it.

Contrary to what happens on Posix platforms, winsock handles are
similar, but different from file handles.  So much so that using
socket handles and respective file descriptors in Posix-style calls
like 'write' cannot be done without some non-trivial jumping through
hoops.

So the fact that we use SetHandleInformation for sockets doesn't
necessarily mean we should copy the code to file handles just because
we can.

In general, Windows support code in Emacs is tricky and there's more
in it than meets the eye, so based on long and hard-won experience I
submit that we should only change it if and when it breaks, and
preferably only for situations in which it breaks.

?? As usual: you invoke Emacs from a cmd window with redirection.  For
example:

    c:\>emacs > output.txt
or
    c:\>emacs 2> error.txt

You can then launch a child process which writes to stdout/stderr and
see that Emacs and the child process do not write to the same file.

What ProcExp64 shows is a good sign, but I'd prefer to test also some
redirection like above, with Emacs and the sub-process both writing to
the same stdout/stderr stream, which would allow to verify positively
that they write to different places.

Thanks.

Okay, I have tested with this lisp exp:
    (print 10 #'external-debugging-output)

10 is printed in the stdout/stderr on the console.

Then try again with
    (start-process-shell-command "test" nil "emacs -Q --batch --eval
\"(print 123123 #'external-debugging-output)\"")

The child emacs process is spinned up but nothing is spewed to the
current console
output.  Does that correct and prove that they don't share the handle?

Not clearly enough.  Consoles are tricky on Windows.  It is better to
start Emacs with stderr redirected to a file (I've shown how to do
that in a previous message), and then see that what the child Emacs
writes to external-debugging-output does not appear in that file.

Also, instead of start-process please use call-process.  That's
because start-process redirects the stdout/stderr handles of the child
process to the pipe from which the parent Emacs process reads, and
that makes the experiment more complex and harder to reason about.

And one more thing: when using "emacs --batch", it is easier to use
'message' to write to stderr; no need to 'print' via
external-debugging-output.

Okay, I've tried with redirecting the stderr to file and then use
    (print 10 #'external-debugging-output)

10 is printed in the file.

Then try with
    (call-process "emacs" nil nil nil "--batch" "-Q" "--eval"
"(message \"20\")")

The child emacs process is created but nothing appended to the output file.
Is that okay?

I have the Emacs binary prebuilt here for UCRT [1], please give it a try if you
want to test more.

Yes, thanks.  I've now installed the change on the master branch (with
some minor edits to better comply with our coding and formatting
conventions).

I won't have time to do that, but others are encourage to test this
build.

Thanks!

Re: MPS: Win64 testers?

By the way, @Pip Cet, have you been able to build 64bit Emacs with MPS?

I've tried to build them but Emacs crashed as soon as temacs was
trying to bootstrap.
Here is the patch I used for MPS though

Did you run the MPS test suite, and if you did, did all the tests
succeed?

It is not recommended to try the MPS build of Emacs as long as the MPS
library doesn't pass the tests with flying colors.  The patch to
mpstd.h is the first place to look for possible issues.  E.g., why is
MPS_PF_ALIGN 8 and not 16?  Also, did you audit all the places
conditioned on MPS_BUILD_MV and MPS_PF_W3I6MV and made sure they are
conditioned on MPS_BUILD_GC and MPS_PF_W3I6GC when the MinGW64 build
needs the same code as the 64-bit MSVC build?

(I assume you mean for Microsoft Windows).

Yes, I have.  It's even started on a machine running Microsoft Windows,
though I'm usually limited to testing on wine, and even that binary was
built using wine.

That's probably the setjmp thing, worked around in my tree at
https://codeberg.org/pipcet/emacs-android (sorry about the repository
name, it's no longer accurate).  Note that there are "Actions" available
which have artifacts that you can download and test, if you are so
inclined.  Right now, for me, the ucrt64 build doesn't work but the
64-bit mingw32 build does.

If you're interested in testing this, please let me know which tree you
use so I can provide a patch that applies there and just contains the
setjmp fix.

I must confess I haven't done that yet. As it has been decided to
deliberately break Emacs CI/CD using Wine, though, I'm not sure there's
any point.

I don't believe we use that macro anywhere (scratch/igc uses 8 byte alignment on
all platforms) but yes, MPS_PF_ALIGN should be 16.

I'm pretty sure I did, but I use a slightly different patch
(https://codeberg.org/pipcet/mps): Please be aware that this code does
run Emacs, but hasn't passed the test suite, so pretty much the only
thing you should be doing with it is to run the test suite.

Also, please keep in mind that -fno-omit-frame-pointer may be required
for GCC when optimizing. I spent entirely too much time tracking down a
bug that was ultimately due to that missing flag.

Yes, all succeeded except the forktest, which I guess doesn't work on Windows
anyway.  I've tried it with both mingw64-i686, mingw64-x86_64 msvcrt and ucrt
version, the 32bit Emacs build doesn't crash.

Both 8 and 16 passed the mps's test suite and both crash Emacs at
temacs bootstrap
in my case.  I'm using this to run the test suite btw
    ../tool/testrun.sh -s testrun w3i6gc/cool

It would be great, I'm using the tip of scratch/igc branch merge with
master.  The
tree is here https://github.com/kiennq/emacs/tree/scratch/igc

I used this instead, from a Windows Command Prompt window running
cmd.exe:

   ..\tool\testrun.bat w3i3gc cool testrun

(you'd need to replace w3i3gc with w3i6gc, of course).  This is
specific to Windows, so it doesn't run forktest and other non-relevant
tests.

Yes, this passed as well.

Applied this patch and I can get an ucrt64 build that's working fine so far :D.

Hi Kien,

is there a way I can test your build?
I have access to a Windows 11 machine during weekdays, and I use Emacs
constantly in it. Currently rocking a MinGW64 build :)

Thank you,

What is the difference between these two builds?

The way forward is to run the crashing Emacs under GDB and show the
backtrace with relevant information when it crashes.

Mine is built with MinGW64, following the instructions in the Emacs

I will try, didn't have luck setting up GDB in Windows in the past, but
that was many years ago.

I got a backtrace. There's a lot of debug info that is missing, but
maybe it helps.

Looking at the "eln-cache" directory, maybe the native-compiled code is
not compatible between the two versions? I am running the same init
directory for both builds.

Thanks, but your build seems to be stripped of debug symbols, so the
backtrace is not very useful.  If you build your Emacs yourself,
remove the -s switch from the link command line, and then rebuild
Emacs and try reproducing the problem again.

That cannot happen: Emacs will not load incompatible *.eln files.

Actually, it can, if one is dumb enough to change the ABI without
bumping the relevant #define.  Andrea helpfully pointed out to me how to
bump the ABI version to prevent that happening after I had to change the
ABI to accomodate unaligned 'setjmp' calls.  And then I must have
forgotten to actually do that, or it somehow got lost during rebasing,
and I sent kiennq a patch without the relevant line in it.  Sorry, my
fault entirely.

So, in essence, you're right, the eln cache will have to be manually
nuked for now.

Will wait for Kien to provide a new build then.
Or instructions on how to create one - although I am not sure I will be
able to install all the components, I don't own this particular device.

Oh, I did strip the symbols when building Emacs.  Let me create a new build.

Btw, I'm switching to building msix file instead of a normal zip file for
distribution.  You can always rename the file to zip to extract it.

Hi Kien,

I ran both that version and the next one. I attached a backtraced of the
latest version. It crashed when I opened Gnus.

Did it crash outside of gdb?

You probably know this, but MPS uses SiGSEGV internally for its
barriers.  If you haven't, please try continuing after a segfault until
you hit terminate_due_to_signal, which is only called if the segfault
couldn't be handled otherwise.

Sorry if this is redundant

It isn't redundant, as I didn't know that, so this explanation is very

AFAIU, it is not a crash. SIGENV is used by MPS internally.

You need to tell gdb skip SIGENV signals:

- Run Emacs with GDB
  : cd src
  : gdb --args ./emacs -Q
  : handle SIGSEGV nostop noprint
  : run

The recipe is much appreciated, Emacs stopped responding and I thought
it was the same crash I had before (in the very first build Kien
provided).

I am not familiar with gdb at all - and it shows =/

I was running this version today:

https://github.com/kiennq/emacs-build/releases/tag/v31.305.20240819.4794ea5

Had two different crashes, hope that these backtraces are more useful
(thanks again to Pip and Ihor for their help)

bt2 happened when I opened a website with EWW from the bookmark list.
bt3 while using Gnus.

I get the impression libgnutls is involved in both - but as established,
I am far of being a GDB expert :)

Thank you, that's very useful.  Indeed, it looks like the
Windows-specific code hands off a pointer to MPS-managed memory to
GNUTLS to use as a cookie, while other OSes use an FD number cast to an
intptr_t cast to void *.

That looks very likely, thank you again.  I'll have to install gnutls on
my wine system to try to reproduce it, but if it is the problem I
described above it should be easy enough to fix.

You are talking about this line in emacs_gnutls_pull:

  emacs_gnutls_transport_set_errno (process->gnutls_state,
                                    errno == EWOULDBLOCK ? EAGAIN : errno);

which causes us to call GnuTLS thusly:

  gnutls_transport_set_errno (state, err);

is that right?  Does this mean we will have to audit all our calls to
external libraries and make sure we never pass to them any part of any
Lisp object?  That's a tough requirement; it's very easy to miss some
such use, which then triggers segfaults.  Am I missing something?

Btw, I tried using EWW in my MinGW MPS build, and it didn't crash.  Is
it possible to have a reproducible recipe for this?

Now I understand: the -g3 option is missing.  In addition, builds of
development versions should not use --disable-build-details, it omits
several details that are very useful for debugging problems.

I meant this code in gnutls.c:

  if (proc->gnutls_initstage < GNUTLS_STAGE_TRANSPORT_POINTERS_SET)
    {
# ifdef WINDOWSNT
      /* On W32 we cannot transfer socket handles between different runtime
	 libraries, so we tell GnuTLS to use our special push/pull
	 functions.  */
      gnutls_transport_set_ptr2 (state,
				 (gnutls_transport_ptr_t) proc,
				 (gnutls_transport_ptr_t) proc);
      gnutls_transport_set_push_function (state, &emacs_gnutls_push);
      gnutls_transport_set_pull_function (state, &emacs_gnutls_pull);
# else
      /* This is how GnuTLS takes sockets: as file descriptors passed
	 in.  For an Emacs process socket, infd and outfd are the
	 same but we use this two-argument version for clarity.  */
      gnutls_transport_set_ptr2 (state,
				 (void *) (intptr_t) proc->infd,
				 (void *) (intptr_t) proc->outfd);
      if (proc->is_non_blocking_client)
	gnutls_transport_set_errno_function (state,
					     emacs_gnutls_nonblock_errno);
# endif

      proc->gnutls_initstage = GNUTLS_STAGE_TRANSPORT_POINTERS_SET;
    }


That hands a pointer to 'proc' to gnutls, and if 'proc' subsequently
moves, emacs_gnutls_push or emacs_gnutls_pull will try to dereference a
stale pointer.

Synchronous calls do not need to be changed, only asynchronous callbacks
that currently use a pointer to a Lisp object as their cookie.

I'll try coming up with one, though that's probably just going to mean
adding (igc-collect) after the gnutls handshake somewhere in the Lisp
code.

By the way, I fully agree more debugging information would be helpful.

But the pointer to 'proc' is passed to GnuTLS for the sole purpose
that GnuTLS passes it back to our callback, emacs_gnutls_pull.  GnuTLS
itself does not (and cannot) use that pointer, for the obvious reasons
that it knows nothing about our objects.

But emacs_gnutls_pull is not an asynchronous call, it is called when
Emacs calls GnuTLS to read from the connection.  So how this could be
a problem?

And what do you mean by "asynchronous calls"?  For example, you can
see in w32font.c that we call certain Windows APIs which work by
enumerating objects of some kind and calling our callback for each
such object (the callback that does with each object what it needs to
do).  Is this an "asynchronous call"?  If not, what is?

Thanks.

But a clear understanding of what causes these segfaults is also
needed, because Emacs is full of similar callbacks, especially on
Windows, where many APIs we use work with callbacks.

That is my understanding as well.  I'm not sure why you think that's a
"but", though.

A pointer to memory managed in a copying pool, stored outside of
MPS-managed memory, as 'proc' presumably is (in malloc()ed memory, I
would guess, or maybe in a static location somewhere), must be pinned
somehow, so MPS does not move it during GC.

You're right, it's called synchronously, but uses the callback+cookie
convention usually used for asynchronous callbacks.

It doesn't look asynchronous to me, though I'm not sure we're talking
about the same code.  The LPARAM arguments referring to stack locations
are fine, because the stack is known to MPS.

MPS needs to know about any pointers to MPS-managed memory.  In
particular, if the cookie is a pointer to MPS-managed memory, and it's
stored in non-MPS-managed memory (such as by an external library), that
will cause problems because MPS believes it is free to move the memory
the pointer points to, but it can't update the pointer itself, so it
will become invalid and dereferencing it will cause segfaults.

On the other hand, pointers that are on the stack are fine, since MPS
treats those conservatively, never moving the blocks of memory they
refer to.

The problem here is that 'proc' might move.  One solution is to make the
cookie a pointer to memory known to MPS, which contains the actual
pointer to the Lisp_Process.  Note that it is not strictly necessary for
the pointer to be allocated with igc_xzalloc_ambig, we could use the
_raw_exact variant.

Because you seemed to say we were passing the object to GnuTLS for its
own use.

Then let's pin it.

But my bother is that we will need to similarly pin many other
pointers and objects, or risk segfaults.  Maybe it means that MPS and
similar igc systems are not suitable for Emacs.

I mean this:

      EnumFontFamiliesEx (dc, &match_data->pattern,
                          (FONTENUMPROC) add_font_entity_to_list,
                          (LPARAM) match_data, 0);

where add_font_entity_to_list is our callback which is called for
every font family and decides whether it matches the font spec; if so,
the callback adds the family to a list that is then used by the caller
of EnumFontFamiliesEx.

Why not tell MPS not to move this pointer instead?  It sounds like a
simpler solution than the change you proposed.  The solution you
propose will complicate large parts of the Emacs code by using double
indirection; pinning a pointer is much simpler.  Or am I missing
something?

> There are other solutions which may be better.

I certainly hope so, since auditing all of our sources for such
gotchas is an impossible job.

How hard is it for Microsoft Windows users to navigate up to #10 and
print the value of (struct Lisp_Process *)p?  Do those gdb commands
"just work" in gdb.exe? Here I get obviously corrupt data, which
indicates to me that the bug is likely to be as I've described.

I think the gdb commands should work in Windows as normal.
However after attaching to Emacs, it becomes unbearably slow to type
any commands
there.  Each keystroke takes around 1s to type and it slows down the
whole Windows
instead of just Emacs.  Is that a known issue and is there a
work-around for that.

In comparison, the same issue doesn't happen with Admin mode Windbg, I can type
normal everywhere else.

Yes: the workaround is to start Emacs from GDB.  When you do that,
Emacs does not install a low-level keyboard hook that it normally
does, and which is the reason for the slow responses to keys if you
attach GDB to Emacs after it already started.

That is interesting, when I run Emacs with gbd attached, it is slower
but not nearly as much as you described. I forced several situations
(LSP with eglot, EWW, opening different modes, Gnus, etc) and I can tell
communication with other processes suffers a lot. But everything else
kinda works the same?

Sorry about that. The problem isn't who uses the pointer, it's who
stores it (gnutls, in memory unknown to MPS) until it's finally used (by
Emacs).

Indeed.  There are quite a few changes along the same lines in the
scratch/igc branch, and it makes me think we need a slightly more
general infrastructure to turn a pointer (or Lisp_Object) known to Emacs
into a void * suitable for passing as a cookie to an external library,
and then for turning the cookie passed to a callback by that external
library back into a pointer (or Lisp_Object) the callback (in Emacs) can
use.

> Maybe it means that MPS and similar igc systems are not suitable for

I believe said infrastructure would be generally useful, because it
allows us to catch another class of subtle bugs that may appear without
MPS: passing a pointer to an external library which is freed by our
traditional GC, which would cause very similar segfaults (if anything,
much trickier to debug) without MPS.

IOW, it's always worth our time to think about why something we pass as
a cookie to an external callback cannot be garbage-collected and/or
copied, regardless of which garbage collector is in use.  The price we'd
pay is to require such cookies to be explicitly deregistered, but we'd
gain a very useful feature (maybe for --enable-checking, maybe enabled
by default): a clear and loud warning informing us that a cookie is
still registered for an object we just tried to GC.

So I think this could improve Emacs in general, even for people who will
never use MPS.

This particular call is safe.  'match_data' lives on the stack, MPS
treats the stack conservatively as pinning every object to which it
might possibly refer, thus 'match_data->pattern' cannot be moved.

The change I proposed is redundant: it tells MPS not to move the
pointer, and it uses a pointer-to-a-pointer to catch potential moves.
Only one part of that is needed, but in both cases, we need to remember
to un-pin/free something.

> The solution you propose will complicate large parts of the Emacs code

Indeed, which is why I'm seriously proposing that cookies for use by
external libraries be generated via an opaque API that has different
implementations:

1. for standard Emacs, where it just returns the pointer
2. for MPS, where it returns a pointer to the pointer
3. for debug builds, where it registers the object so we warn if we try
to GC it, then returns the pointer.

> pinning a pointer is much simpler.  Or am I missing something?

Pinning it certainly is, remembering to un-pin it when we're done with
it is the hard part.  And also something we should always do, since
forgetting to unpin it would result in memory leaks and slower GCs for
the lifetime of the Emacs session.

>> There are other solutions which may be better.

I think I disagree that it's impossible.  We've already caught many of
them (the PGTK and Lucid toolkit fixes were essentially the same
problem), and auditing our usage of such callbacks is necessary anyway
because traditional GC might free (but not move) pointers prematurely,
resulting in subtle bugs which might not be caught for years.

I think working on this issue is worth our time and has the potential to
improve Emacs generally, independently of the MPS branch.

The price we'd pay is that we would be forced to make explicit the point
at which an external library stops using our cookie/opaque
pointer/LPARAM/whatever you want to call it; put differently, it would
force us to think about that question at all, while right now it's
possible just to hope the Emacs object will live for long enough.

I believe the cookies are generally of one of the following types:

- void *
- gpointer
- LPARAM
- WPARAM?

And grepping for these returns a manageable but large set of hits (1865,
most of which are trivial).

We are not coding Emacs from scratch.  Emacs is already a very large
body of code, most of it tested by time and gobs of users and use
patterns.  To start rewriting too much of that means we are losing all
that hard-earned stability, because many corners in Emacs code are not
well known to those who are currently active in development and
maintenance.

So from where I stand, it is definitely a significant problem to make
such vast changes, and the fact that it will help us eventually
doesn't help.  Because if we destabilize Emacs enough, we will lose
our users, which are the only reason Emacs is still alive and kicking.

IOW, we are lucky.  Because match_data could well be a global variable
allocated off the heap, or something else.

If the change is redundant, why did you propose it?

More importantly, we need to have boilerplate code to pin a pointer,
because this will be needed a lot.  The fact that we still don't have
it is unfortunate.

Then we need to figure that out, IMO.

If unpinning is automatic, it won't be forgotten.

With stack marking, I think those bugs are largely a myth, as is
proven by decades of use.  I didn't have a production Emacs crash on
me for the last 20 years at least.

I don't see how we'd destabilize the existing Emacs code by making such
changes; any unconverted code would continue working as it did before
without MPS, and continue not working with MPS.

If your point is that it might be a long time until MPS is stable enough
for very unusual configurations, that is certainly true, and affects
when it's a good idea to enable it for general use.

Which would be a bug both with and without MPS, as nothing protects
match_data.list from GC if it doesn't live on the stack.

Better to solve a problem twice than not to solve it at all?  I don't
see a problem there, to be honest.

(It's morally equivalent to writing

  if (p)
    xfree (p);

even though that's redundant as well.)

> More importantly, we need to have boilerplate code to pin a pointer,

I think it's better to have boilerplate code to turn a (potentially
MPS-managed) pointer into a cookie, and back, and deregister it.  Of
course it's undesirable for pointers to be unnecessarily pinned, so it's
likely we'd end up merely registering a pointer to the pointer with MPS,
and making sure that is traced exactly rather than ambiguously so the
object pointed to can move.

>> > pinning a pointer is much simpler.  Or am I missing something?

I should have been clearer: if we remember to un-pin the pointer, it's
no longer any simpler to pin it than it is just to use a pointer to a
pointer, and the latter approach lets us know about memory leaks and is
better from a GC point of view.

>> Pinning it certainly is, remembering to un-pin it when we're done with

That requires knowledge of the library in question, AFAICT.  To be
honest, I'm not entirely sure I trust the GTK code to get it right.

>> And also something we should always do, since

But that requires knowing when the library stops using the cookie, which
is all but impossible. right?

We may have to clear the object files one by one, then, and warn about
unaudited object files in MPS builds.

I'm not sure what you're trying to get at here. Stack marking, of
course, has the same protective effect with and without MPS, since MPS
marks the stack conservatively.

I'm talking about the code changes, not about what stays unchanged.

And if you don't understand how adding a lot of changes of this
particular kind can destabilize Emacs, then I guess we have very
different perspectives on stability, and this line of discussion
between us is not useful.

Not "for very unusual configurations", for all configurations,
including the most popular ones.  We are touching the most delicate
parts of Emacs, and will probably touch a lot of them (unless we find
some simpler, more reliable way of preventing these problems).

??? We have gobs of those, and know how to protect them.  The easiest
way is staticpro, and there are others.

Not in my book, no.  Since Emacs is stable, we should not add any code
that is not strictly necessary, otherwise we risk unnecessary
problems.

It's nowhere morally equivalent to the above, because it is much
harder to understand what goes on with MPS than to figure out that
xfree tests NULL internally.

Simpler, maybe, but reliability, I will keep insisting, improves if we
think about why it's safe to hand off a pointer to GCable memory to an
externable library.

My point is you'd have to protect it, albeit slightly differently, with
or without MPS.  Not that much changes with MPS, and to say it works
because "we are lucky" is inaccurate.

The master branch may be, but there's nothing wrong with keeping our
options open on scratch/igc rather than leaving in a few "redundant"
safety checks.

I agree, though, that a comment is in order here.

All of them.  I'm quite sure we have a lot of corners the few people
who are using the branch have not entered yet, especially as some bugs
don't happen until GC hits at just the right (or wrong) moment.  Like
this GnuTLS crash, for example.

You can insist all you want, but you will never convince me.  I have
too much gray hair from opinions based on the assumption that we
completely understand what we are doing by such changes and what they
cause in Emacs.  Just stick long enough here and you will see another
example of this fallacy almost every day.

So no, IME reliability definitely does NOT improve by futzing with
this kind of stuff.  Which means we should not do it unless we must.

"Not that much changes" is IMO an understatement of the decade.
Compare the simplicity of staticpro with the complicated dance you
suggested for this GnuTLS issue (which is not different from many
similar changes installed on the branch each time we detect some
similarly "unsafe" use of data structures).  One can use staticpro
without even fully understanding how it works and why.  We have
nothing comparable on the MPS branch, and thus no established
procedure for solving such problems or rules for auditing code for
similar issues.

If we want this branch to ever land on master, we had better handled
it with the same care as we do on master.  Because when we decide to
land it, no one will have time or motivation to go through all this
stuff and "fix" it.  We want Emacs to be as stable the day after this
lands as the day it was before that.  That's how it was for all the
other major features that got merged from feature branches.  Any

The new build is here[1].
Using `eww-mode` doesn't crash Emacs for me anymore. Thank you Pip.

Hi all,

I've been using the build for the last 3 days with no crashes. 
Will report back next Friday, declaring "no crashes" after just 3 days is a bit too naive, maybe :)

Thanks,

Hi,
I got a new crash with mps build.
Here is the backtrace (attached).

By the way, instead of running Emacs under gdb all the time, I figured
out that I can just attach to the `emacs_abort` dialog with a small fix
to ensure the keyboard hook is released beforehand.  The patch for that
is here[1].  @Eli, do you think that's acceptable to merge?  It greatly
relieves the burden of using with debugging Emacs on Windows.

I'm not sure we can do this safely.  There are all kinds of caveats in
the MS documentation.  And it's only useful when Emacs aborts, not
when, e.g., it hits a breakpoint.

Why is it a pain to run Emacs under GDB at all times?  That way we
don't install the hook, and the problem doesn't happen in the first
place.

Because without the keyboard hook running, some of the key combinations
(Windows and Alt + ...) will be handled by Windows instead of Emacs.
That causes using Emacs for a long running time a bit unnatural as I
need to relearn or rebind the key combinations again.  Also, running
under gdb is slow and not enjoyable for using Emacs.

And you really need them while debugging?

Slow because of the hook or because of other reasons?

You should realize that attaching to Emacs when it crashes many times
misses important information, because when Emacs is not running under
the debugger, fatal exceptions go to the top-level exception handler,
which at times loses important information, like exactly which code
caused the crash.  So running an unstable Emacs build outside of GDB
is not recommended on Windows for several good reasons.

In any case, you should be able to invoke remove_w32_kbdhook from the
debugger, as soon as you attach to Emacs.  I hesitate to make the
change you proposed because emacs_abort is called not just when Emacs
is under a debugger, so the change will affect many users who don't
debug Emacs.

Sorry, I didn't notice this email before answering the other one. :)

Yes, that would also solve my issue. The `if` check should be changed to
a `while` loop, as `remove_w32_kbdhook` will just decrease the reference
count if there's still more than one reference to the `kbdhook`.

On the other hand, doesn't this require me to run `gdb` under Emacs's
`src`? So, for others who want to try the pre-built version and get the
debug backtrace, they will need to download the `gdbinit` file or clone
the Emacs source code and run `gdb` from the `src` folder. That can be a
bit of work, though.

Yes.  But it doesn't make sense to seriously debug Emacs in any other
way.  And the MPS build, in particular, needs the setting of SIGSEGV
to avoid stopping due to GC.

That's true, but people who don't have .gdbinit and the sources cannot
usefully debug Emacs anyway.  So I'm not worried about that.

The advantage of this method is that it affects only those who debug
Emacs, not everybody else.  That's a significant advantage in my book.

Can we make it easier for those brave testers by including the gdbinit
file (and, ideally, an indication of where to download the precise
sources used to build Emacs) in the zip file, and print them out when
GDB is started?

For example, your latest crash report has line numbers in it that do not
precisely match those of the scratch/igc branch, and it wasn't
immediately obvious to me how to look them up...

I've included the source info in my build now. It should be under
`invocation_directory/../source_info.txt` of the distribution.  I will
report it together with the full backtrace next time.

For the previous backtrace, its source code is here[1].

We could include .gdbinit in the binary distribution, but it isn't
worth much without the sources anyway.

The sources of development branches are only available from Git
anyway.

Thank you, it does.  I found the bug, but fixing it is going to require
changes to your MPS patch series.

The disassembled code that's causing the problem reads:

   0x000000040013c950 <+1216>:	mov    (%r12),%rdx
   0x000000040013c954 <+1220>:	movq   %rax,%xmm1
   0x000000040013c959 <+1225>:	mov    0x278(%rdx),%rax
   0x000000040013c960 <+1232>:	sub    $0x1,%rbx
   0x000000040013c964 <+1236>:	mov    $0x3,%edx
   0x000000040013c969 <+1241>:	movq   (%rdi,%rbx,8),%xmm6
   0x000000040013c96e <+1246>:	mov    $0x18,%ecx
   0x000000040013c973 <+1251>:	mov    0x20(%rax),%r8
   0x000000040013c977 <+1255>:	punpcklqdq %xmm1,%xmm6
   0x000000040013c97b <+1259>:	call   0x4002061e0 <alloc_impl.lto_priv.0>
   0x000000040013c980 <+1264>:	movups %xmm6,0x8(%rax)
   0x000000040013c984 <+1268>:	add    $0x3,%rax
   0x000000040013c988 <+1272>:	test   %rbx,%rbx
   0x000000040013c98b <+1275>:	jne    0x40013c950 <Fmatch_data+1216>

During the call to <alloc_impl.lto_priv.0> at +1259, the future value of
the cons cell lives only in XMM registers (%xmm1 and %xmm6); while it
was returned from the previous iteration in %rax, that register is
overwritten by the mov at +1225.

This isn't a problem for the first iteration, when the cdr is Qnil,
which is safe to use, but after the first generation, this is the only
place that holds a reference to the list we're building.

alloc_impl can call GC, which will then fail to find a reference to the
list that's being built and collect it, but return to +1264 where the
reference to the freed cons cell is written back to memory.

IOW, we need to make sure that the callee-saved %xmm registers are
properly spilled to the stack and marked conservatively.

However, this patch:

https://github.com/kiennq/emacs-build/blob/main/patches/mps/0004-Fix-register-scanning-on-FreeBSD-and-Linux.patch

replaces setjmp() by a series of assembler statements:

#define STACK_CONTEXT_SAVE(sc)                                  \
  BEGIN                                                         \
    Word *_save = (sc)->calleeSave;                             \
    __asm__ volatile ("mov %%rbp, %0" : "=m" (_save[0]));       \
    __asm__ volatile ("mov %%rbx, %0" : "=m" (_save[1]));       \
    __asm__ volatile ("mov %%r12, %0" : "=m" (_save[2]));       \
    __asm__ volatile ("mov %%r13, %0" : "=m" (_save[3]));       \
    __asm__ volatile ("mov %%r14, %0" : "=m" (_save[4]));       \
    __asm__ volatile ("mov %%r15, %0" : "=m" (_save[5]));       \
  END

This assumes the SysV ABI is in use, which doesn't have callee-saved XMM
registers.  However, GCC (correctly) uses the Microsoft x64 ABI, which
also requires XMM registers %xmm6-%xmm15, as well as general registers
%rdi and %rsi, to be callee-saved
(https://learn.microsoft.com/en-us/cpp/build/x64-calling-convention).

So this patch doesn't work for Windows 64 builds. I'm not entirely sure
that simply removing this patch will make things work, though, because I
don't know how Microsoft's UCRT implements setjmp.  MPS relies on it to
store the value of the callee-saved registers without any further
mangling, on the stack, in aligned words.

A safe (but very slightly slower) solution would be to simply store the
registers twice, once using setjmp() and once using the assembler
statements.  Would that be acceptable for your build?

That works for me. Thank you.
However, let me try to modify the patch to exclude Windows there.  The
MPS supports Windows build so I think it should work without the patch
that's meant for FreBSD and Linux.

That makes sense, let's try that!

Thanks, I made that change and installed the result on the master
branch.

Hi all,

I am still using the version from August 25th, didn't have any more
crashes or problems.
I have been using this version less than usual because we moved some
work to other environment (where I can't install this one). But I had
web navigation, email, some light coding with no hiccups.

Is there anything else I could do to help?

Thanks,

Use the pretest of Emacs 30 as much as you can and report any issues.

Thank you!

Did this happen randomly, or is it reproducible?

Hmm, we're going to need more information on that one.  Ideally, the
next time a crash like that happens, it would be great if you could keep
the GDB session open so we can gather more information from the crash.
Also, "bt full" is better than "bt".

What I suspect is that we failed to trace an object, probably a face
(but maybe it was an ordinary vector), during the previous GC.  I don't
see how that could have happened, yet...

Were you using non-ASCII faces at the time?

Yes, I'm using nerd-icons which is full of non-ASCII characters.

It doesn't seem to be because of hooks as I can still type, a tad slower
than normal.  On the other hands, whenever a compiled package is loaded,
it's really slow.  I do delay loading a lot so using Emacs under debugger
has not been enjoyable so far.

The mps build is quite stable for me and only crash once in a while so

Got it, I will try that next time.  It will need some setups as at the
time the debugger is attached, typing is really slow so it's impossible
to type anything long.
Btw, I think that at the time emacs_abort (for Windows) is called, the
process is going to crashed anyway unless the debugger is attached and
do some hot patches.  The function is either abort or wait for a
debugger to attach anyway.  Is there another way to recover and continue
to use Emacs?

Thanks, but the backtraces show only minimal information, not even the
arguments to functions, let alone line numbers.  How (with what
compiler switches) was Emacs compiled?  The value of
system-configuration-options should be of help in answering this
question.

Without line-number information it is hard to guess what could be
causing these crashes.  And even if I could guess, I doubt that the
debug info in the binary is rich enough to answer important questions
like values of variables involved in the crash.

I am still using the build that Kien graciously provided, maybe I should
build my own so we have better debug info.

Not sure how building the UCRT version differs from the usual MinGW64
recipe shared in the INSTALL.w64 file. I assume I need a different
compiler?

On Monday I found out $WORK has a full Visual Studio license for all
developers, so I have access to those compilers :) an unexpected
surprise (my team in particular is more Python oriented)

No, the compiler and everything else is the same.  What you need is
(a) make sure compiling a program links against UCRT (it's some
configuration switch in MinGW64, perhaps even the default, I don't
know), and (b) make sure all the auxiliary libraries you download from
the MSYS2 site, like GnuTLS and other libraries that Emacs uses, are
all built for UCRT as well (this is something you should tell pacman
when you tell it to download and install those libraries).

It is best to ask on the MSYS2 forum, because I have only a vague idea
about the practical aspects of this.

Visual Studio will hardly help, because Emacs does not support the
Microsoft compilers, not anymore.  You must use MinGW.  Only the DLLs
installed by Visual Studio can be of any use for Emacs, and even then
I'd recommend to prefer the corresponding MSYS2/MinGW64 DLLs.  E.g.,
if a DLL was built from C++ sources, using the version provided with
Visual Studio will in many cases cause unresolved externals during
linking.

Yes, there is. It makes assumptions about the API implementation that
valid implementations of the Windows API do not satisfy. Wine until last
week is one example; given that the bug wasn't reported in 20 years, we
can assume that no other popular application relies on this particular
detail, so relying on it even in MSVCRT builds is unsafe.

IMHO, the only thing the first patch is missing is a comment reminding
us to remove the old code if and when support for Windows 95/98 is
dropped.

Since the UCRT is the replacement of MSVCRT, just putting that behind
an ifdef without
checking for the function pointer is also fine to me.  Eventually, the
UCRT, which
is receiving all of the security fixes, should be replacing the MSVCRT.

I disagree with you, and I already stated this disagreement earlier,
so there was no reason to reiterate your POV, which was already heard
and noted.

(Your mistake is that you look at this as if Windows were a
free-software OS, where all the sources are available for study and
there are a lot of people who understand the internals enough to make
such decisions.  That is not the case, and so the fact that this code
worked for us virtually without changes since it was first written
back in 1996, and still works today in the MSVCRT builds, is, from
where I stand, an overwhelming evidence that we should only mess with
it if and when it breaks.)

Indeed, that's what I'm seeing with wine, too.  BTW, the Wine issue has
been fixed and it now faithfully emulates the MSVCRT behavior when
pretending to be ancient Windows.

We still need to call it through a function pointer to support Windows
98/95, right?  And, of course, once we've done that, we need to find
testers for most or all Windows versions to verify the streams are
indeed not being inherited.

Would you be willing and able to help with that, maybe?

No, we don't, because there's no UCRT on those old versions, and Emacs
linked against UCRT will not run on them.

MinGW64 tossed support for those old versions of Windows long ago, so
any Emacs build done with MinGW64 is likely not to run on those old
version, definitely the 64-bit builds.
