Hi,

Bootstrap got to fail on Cygwin since yesterday.  An error occurs
at least when performing batch-update-autoloads as follows:

[...]
Wrote /Work/emacs/lisp/mh-e/mh-loaddefs.el
(No changes need to be saved)

I can run bootstrap-emacs.exe with the -Q option but I have no
clue to examine it.  Please help.

I did a similar report on emacs-devel:

http://lists.gnu.org/archive/html/emacs-devel/2013-06/msg00333.html

Now I have discovered that trunk rev. 112858 build fine while rev. 
112859 fails as described. These are the changes that have broken the 
bootstrap on Cygwin:

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

  3        Chain glib's SIGCHLD handler from Emacs's (Bug#14474).
  4        * process.c (dummy_handler): New function.
  5        (lib_child_handler): New static var.
  6        (handle_child_signal): Invoke it.
  7        (catch_child_signal): If a library has set up a signal handler,
  8        save it into lib_child_handler.
  9        (init_process_emacs): If using glib and not on Windows, 
tickle glib's
  10        child-handling code so that it initializes its private 
SIGCHLD handler.
  11        * syssignal.h (SA_SIGINFO): Default to 0.
  12        * xterm.c (x_term_init): Remove D-bus hack that I installed 
on May
  13        31; it should no longer be needed now.
=================================


Ciao,
  Angelo.

Hello.

This sounds like a bug in GLib.  Put a breakpoint at g_thread_abort to get a useful backtrace.

Are you linking with libxml2?  These URLs:

http://91r.net/ask/15791784.html

http://xmlsoft.org/threads.html

suggests that Emacs may not be initializing
libxml2 properly.

You should be able to tell whether you're linking
with libxml2 by looking at the 'make' output,
or by running 'ldd src/temacs'.

Hmm... I configure with:

What happens if you configure --without-xml2?
Something like this, say:

"${source_dir}"/configure --prefix="${prefix_dir}" --without-xml2
make clean
make

Hmm... I have just verified that my builds on Kubuntu uses xm2 too, and 
the same rev. that fails to bootstrap on Cygwin, there builds fine..

I am afraid for you, but what you suggest fails in the same manner:

I would have been surprised if it had worked.. As I explained, on 
GNU/Linux Kubuntu 12.04 Emacs Trunk bootstrap fine with the XML2 support..


and now, really, Good Night!!!


Ciao,

(PS. When I replay, TB refuses to send the replay to the address 
14569@debbugs.gnu.org, I need to change it manually into 
bug-gnu-emacs@gnu.org, IS there some tricks I can do to avoid this? TIA, A.)

As you have seen, what you propose fails... but also this fails:

The error is not even consistent, it only occurs sometimes.  There seems to be a random memory corruption going on.  Sometimes bootstrap fails with a core dump, sometimes with

GLib (gthread-posix.c): Unexpected error from C library during 'pthread_setspecific': Invalid argument.  Aborting.

And this is while compiling .el-files.  It is not crashing in the same .el-file, many files compile just fine before the crash happens (if it happens).  Redoing the make after a crash usually produces an Emacs executable.  It seems to run fine, but I haven't run it for a very long time.  Maybe the bug manifests itself only in bootstrap-emacs when using GLib?

I got one backtrace for the setspecific error:

As there seems to be no good memory debuggers for Cygwin, this will be hard to find.  I still think it is an GLib/Cygwin error.

Can you find out (by looking at the glib sources) when and why would
g_spawn_close_pid call 'abort'?  It might give us some clues.

Also, what process (or is it a thread?) did glib spawn here, and why?

That's a bug; --without-all should disable file notification.

I installed a fix in trunk bzr 112928.
You'll also need --without-x (or some other non-glib X toolkit)
to suppress glib.

Please update to the trunk and then run:

   ./autogen.sh
   ./configure --without-all --without-x

This should build you a glib-less Emacs.  On my Fedora 17 host,
the shell command 'ldd src/temacs' reports:

	linux-vdso.so.1 =>  (0x00007fffcbffe000)
	libacl.so.1 => /lib64/libacl.so.1 (0x000000386cc00000)
	librt.so.1 => /lib64/librt.so.1 (0x000000385ea00000)
	libtinfo.so.5 => /lib64/libtinfo.so.5 (0x0000003868a00000)
	libpthread.so.0 => /lib64/libpthread.so.0 (0x000000385e600000)
	libm.so.6 => /lib64/libm.so.6 (0x000000385de00000)
	libc.so.6 => /lib64/libc.so.6 (0x000000385da00000)
	libattr.so.1 => /lib64/libattr.so.1 (0x000000386ba00000)
	/lib64/ld-linux-x86-64.so.2 (0x000000385d600000)

Arguably, --without-all should disable some of these
remaining libraries, too; but at least it now disables glib.

On POSIX platforms, g_spawn_close_pid does nothing.
So apparently glib is compiled for Windows (i.e.,
glib/gspawn.c is not being compiled, but glib/gspawn-win32.c
is being compiled instead.

The Emacs code that tickles gnulib is written this way:

#if defined HAVE_GLIB && !defined WINDOWSNT
      /* Tickle glib's child-handling code.  Ask glib to wait for Emacs itself;
	 this should always fail, but is enough to initialize glib's
	 private SIGCHLD handler.  */
      g_source_unref (g_child_watch_source_new (getpid ()));
#endif

I did notice one problem: the code previously invoked
g_child_watch_source_new (0), which is not safe if Emacs
has already forked -- perhaps Cygwin was doing that?
So I changed it to g_child_watch_source_new (getpid ())
in trunk bzr 112929.

Another thought is that there may be a mismatch between
glib builds.  Since WINDOWSNT is not defined for Cygwin builds,
a Cygwin Emacs will call g_child_watch_source_new.  My reading of
the bleeding-edge glib source code is that a Cygwin glib should call
waitpid and mess with the SIGCHLD handler, just as a
POSIX glib would, so the above Emacs code is correct.
But if you're building under Cygwin and linking with
a mingw glib, the above code may well run into problems.
Is this a possibility that we should worry about?

No, this is not the case.  I just replicated the glib build to make 
sure.  Cygwin is a POSIX platform, to the extent possible.

No.  This does not happen.  The Cygwin glib maintainer takes pains to 
patch the source if necessary to make sure that Cygwin is not treated 
like Windows.  See, for instance, the attached patch that is used in the 
Cygwin build.

So, in this patched glib, what does g_spawn_close_pid do, and under
what circumstances could it call 'abort'?

It does nothing.  So Jan's backtrace is suspect.  I don't know if that 
could result from optimization, but I'll build a non-optimized glib and 
see if I can get a more reliable backtrace.

It is suspect, the error message does belong to g_private_set (frame #2).  Frame #1 should have been g_thread_abort.  If there is indeed a memory corruption, such as a stack overwrite, that might explain it.  Or it might just be that gdb is in error.

The build BTW, was un-optimized.

That is the Emacs build, I did not build GLib, so that was probably optimized.
We have seen in Emacs that breaks in abort shows strange backtraces.

After that I tried `make -k' for four times and I got to get no
such error.  Though it must not be a right solution, the built
one works so far.  In the early three `make -k', the error
happened when byte-compiling an *.el file, but each time an *.el
file causing the error varied.  So, this isn't due to a Lisp code,
I guess.  For instance, one happened when compiling nntp.el, but
I can build Ma Gnus (from the Git master) without causing such
an error using this Emacs.  Anyway I will report it again if I
have a chance to get a C backtrace or other.

Hi.

It is crasches much less with this change, about one in three builds.  Previously it crasched on every build. 
Some sort of race condition, perhaps?

As for what the threads do, I don't know. There are five threads created when Emacs byte-compiles one file.

That's surprising -- I'd expect it to either crash not
at all, or to crash just as often as before.

Can you strace a failing instance?  The syscall pattern
may help explain things.

Well, the crashes are kind of random, so maybe the randomness just shifted a bit on my system?

I do get segmentation violations sometimes instead of the pthread abort.  
But I haven't been able to get one while running the debugger yet

Which version of glib are you using?  Older versions
require special handholding with initialization,
e.g., g_type_init, and perhaps we're running into
that problem -- or perhaps you're using a newer
version and its autoinitialization code isn't working.

Also, a bit of Googling found this bug:

http://cygwin.com/ml/cygwin/2012-05/msg00472.html

where signals may nor may not reach the correct thread
with pthread_kill.  Emacs uses pthread_kill to redirect
SIGCHLD to the main thread; if this is sent to a random
thread instead, that could explain the random crashes
you're observing (maybe a recursive runaway in a
signal handler?).

Glib 2.32.3.  If g_type_init isn't run, an error message will be shown at once.  As it is now, Emacs runs for a bit before crashing.

Could be.  Unfortunately, Emacs does not crash when running under strace.

Cygwin developers, I'm worried about a Cygwin bug where
pthread_kill may not send a signal to the correct thread.
This bug may be causing Emacs to crash.  The Cygwin bug is
discussed in this thread:

http://cygwin.com/ml/cygwin/2012-05/msg00472.html

Emacs uses pthread_kill to redirect
SIGCHLD to the main thread; if this is sent to a random
thread instead, that could explain the random crashes.

My question is: does this bug still exist with Cygwin,
and if so is it likely to get fixed soon?

More details about the Emacs bug can be found here:

  http://bugs.gnu.org/14569

Briefly, Emacs is crashing randomly on Cygwin ever since it started
doing this:

  /* Tickle glib's child-handling code.  Ask glib to wait for Emacs itself;
     this should always fail, but is enough to initialize glib's            
     private SIGCHLD handler.  */
  g_source_unref (g_child_watch_source_new (getpid ()));

After this newly-inserted code, Emacs finds out what the
child signal handler was:

  /* Now, find out what glib's signal handler was, and store it
     into lib_child_handler.  */
  struct sigaction action, old_action;
  emacs_sigaction_init (&action, deliver_child_signal);
  sigaction (SIGCHLD, &action, &old_action);
  eassert (! (old_action.sa_flags & SA_SIGINFO));
  if (old_action.sa_handler != SIG_DFL && old_action.sa_handler != SIG_IGN
      && old_action.sa_handler != deliver_child_signal)
    lib_child_handler = old_action.sa_handler;

Emacs's SIGCHILD handler, deliver_child_signal, arranges the
signal handling to occur in the main thread (to avoid races
within Emacs), like this:

  int old_errno = errno;
  bool on_main_thread = true;
  if (! pthread_equal (pthread_self (), main_thread))
    {
      sigset_t blocked;
      sigemptyset (&blocked);
      sigaddset (&blocked, sig);
      pthread_sigmask (SIG_BLOCK, &blocked, 0);
      pthread_kill (main_thread, sig);
      on_main_thread = false;
    }
  if (on_main_thread)
    handle_child_signal (sig);
  errno = old_errno;

And handle_child_signal, which runs in the main thread, does
a bunch of Emacsish things and then invokes lib_child_handler (sig),
which is glib's SIGCHLD handler.

All this works just fine on Fedora and other platforms; but it
doesn't work on Cygwin.

You pointed to an archived mail messages which implies that was fixed
more than a year ago.  What makes you think it is still a problem?

I'd expect that if it was still a problem our emacs maintainer would
be on top of it.

Caveat: I'm not a Cygwin developer, and don't even use Cygwin.

It should be easy to instrument deliver_child_signal so that it prints
something when it redirects SIGCHLD, and then the Cygwin users could
see if there's such a report immediately before the crash, or at all.

Unfortunately, the emacs maintainer doesn't have any idea why the recent 
emacs changes are causing random crashes on Cygwin.  It's almost 
impossible to catch this under gdb; and the one time it was caught, the 
backtrace didn't make sense.  Also, the crash doesn't occur when emacs 
is run under strace.

I'm not going to speculate on whether the problem is caused by a bug in 
Cygwin's pthread_kill.

What are the difficulties of catching this when Emacs is run under
GDB?

P.S.  I removed the Cygwin list from the adressees, as I don't think
we have any evidence at this time that this is a Cygwin problem.

Its not difficult, but takes some time.  The error happens when make compiles one lisp file at the time with emacs.  It appears to be random so it does not crash in the same lisp-file.  Thus, you have to start emacs from gdb, and repet run, quit in gdb for each lisp file until it crashes.  Running in gdb is slow with cygwin, and running in gdb makes the bug appear less often.

The make rule is in lisp/Makefile, compile-onefile.

Would it make things easier if compile-onefile is modified to invoke
Emacs under GDB to begin with, using the --args switch to GDB?

Out of curiosity, I tried the test cases I found in that thread, more 
precisely here:

   http://cygwin.com/ml/cygwin/2012-05/msg00434.html


and the results are:

Are the errors in the last test case to be expected under the 20130612 
snapshot (CYGWIN_NT-5.1, 1.7.21s 20130612 21:06:59, i686 Cygwin)?


Ciao,

I can replicate this on my system, consistently.  There's clearly a 
problem, but it's not the same as in the original Cygwin bug report.  In 
the present case, the signal is received by the right thread, but 
something goes wrong afterwards.

I'm attaching the test case for ease of reference.

Yeah, I missed that.  Sorry for the noise.

I've revised the test case (attached) so that it checks for EINTR.  It 
now runs as expected on Cygwin:

Testing pthread_kill()

Thread 0 starting (0x800102a8)
Thread 1 starting (0x80010348)
Thread 2 starting (0x800103e8)

Sending SIGUSR1 to thread 2 (0x800103e8)
Thread 2 executes signal handler (0x800103e8)
Thread 2 woke up just fine
Sending SIGUSR1 to thread 1 (0x80010348)
Thread 1 executes signal handler (0x80010348)
Thread 1 woke up just fine
Sending SIGUSR1 to thread 0 (0x800102a8)
Thread 0 executes signal handler (0x800102a8)
Thread 0 woke up just fine

So there's no reason to think that a pthread_kill bug is causing the 
problem.  Back to the drawing board.

Can you tell me exactly how you modified the rule for compile-onefile? 
I tried but kept getting errors, so I'm obviously not doing it right.

Thanks.

There is something fishy with quoting, Cygwin and gdb so you have to comment out BIG_STACK_OPTS. 

Then I added:

emacsdbg = EMACSLOADPATH=$(lisp) LC_ALL=C gdb -ex 'b abort' -ex run --args $(EMACS) $(EMACSOPT)

and used it:

compile-onefile:
	echo Compiling $(THEFILE)
	@# Use byte-compile-refresh-preloaded to try and work around some of
	@# the most common bootstrapping problems.
	$(emacsdbg) $(BYTE_COMPILE_FLAGS) \
		-l bytecomp -f byte-compile-refresh-preloaded \
		-f batch-byte-compile $(THEFILE)

The modifications where done in the generated Makefile. I guess it will work in Makefile.in also.

This should make your life quality better, I think:

  emacsdbg = EMACSLOADPATH=$(lisp) LC_ALL=C gdb --batch-silent --return-child-result -ex 'b abort' -ex run --args $(EMACS) $(EMACSOPT)

This causes gdb to exit, whether or not the breakpoint was hit, without 
giving the user a chance to get a backtrace.  I tried adding

   -x $(lisp)/commands.txt

where commands.txt contains

   commands
   bt
   end

but that didn't work.  gdb still exited (with an error) when 
compile-onefile failed, but it didn't print a backtrace first.  There 
has to be a way to get a backtrace when gdb runs in batch mode.  Do you 
know how, Eli?

Sorry, I went overboard with --batch-silent, please use --batch
instead.  (--batch-silent prevents the backtrace from showing up.)

As for displaying the backtrace, just add the "bt" command to the
chain, like this:

  emacsdbg = EMACSLOADPATH=$(lisp) LC_ALL=C gdb --batch --return-child-result -ex 'b abort' -ex run -ex bt -ex cont --args $(EMACS) $(EMACSOPT)

GDB executes the commands given via -ex in order, so think of this as
if you typed the commands whenever GDB shows its prompt.

Note that I also added "continue", to let Emacs exit abnormally after
hitting the breakpoint (or a segfault).  When neither the breakpoint
nor a fatal signal fire, GDB will say "No stack." when Emacs exits
normally, but that's harmless.

Thanks, Eli.  I replaced "bt" by "thread apply all bt", which probably 
didn't provide additional useful information.  I then ran "make 
bootstrap" followed by repeated "make -k" until the bootstrap completed. 
  Early in the process there were two crashes with SIGSEGV, for which I 
got backtraces (attached).  In both cases the crash occurred in 
gmalloc.c, which probably explains why we're seeing problems only on Cygwin.

After that there were many compile failures with errors like those that 
others have reported:

Compiling gnus/gnus-cache.el
GLib (gthread-posix.c): Unexpected error from C library during 
'pthread_setspecific': Invalid argument.  Aborting.
Makefile:254: recipe for target `gnus/gnus-cache.elc' failed

But these compilations didn't invoke gdb, apparently because they 
involved Makefile targets other than compile-onefile.  So I didn't get 
any more backtraces.

I can modify the Makefile further if necessary, but the attached 
backtraces are a start.

No, I think these failures didn't go through 'abort', that's why you
didn't get the backtrace.  You need to look at the pthread sources in
the file mentioned, and find out where to put the breakpoint to catch
that error.

The error message comes from 'g_thread_abort', which calls 'abort'.  The 
reason there was no backtrace is exactly what I said.  I know that's the 
case because I removed the "@" at the beginning of the Makefile rule so 
that the command would get echoed, but it didn't get echoed in the 
compilation above (and others like it).  On the other hand, it did get 
echoed in the SIGSEGV examples that I mentioned in my previous mail.

Sorry, I forgot that there's one more rule:

  # An old-fashioned suffix rule, which, according to the GNU Make manual,
  # cannot have prerequisites.
  .el.elc:
	  @echo Compiling $<
	  @# The BIG_STACK_OPTS are only needed to byte-compile the byte-compiler
	  @# files, which is normally done in compile-first, but may also be
	  @# recompiled via this rule.
	  @$(emacs) $(BYTE_COMPILE_FLAGS) \
		  -f batch-byte-compile $<

Instrument it in the same way, and you should be able to catch the
other problems as well.

Thanks.

Thanks.  I've now got some further backtraces, this time involving glib. 
  I'm using glib-2.34.3, which I compiled without optimization.  There 
are two kinds of problems, in addition to the gmalloc.c crashes that I 
mentioned earlier.

1. When the 'abort' breakpoint is hit, the backtrace (abbreviated) looks 
like this:

#0  0x6acdb0f8 in abort from /usr/bin/cygglib-2.0-0.dll
#1  0x6acd6eb0 in g_thread_abort at gthread-posix.c:76
#2  0x6acd7758 in g_private_set at gthread-posix.c:1026
#3  0x6acb9fc2 in g_thread_self at gthread.c:1003
#4  0x6ac93ee3 in g_main_context_iteration at gmain.c:3351
#5  0x6ac956ea in glib_worker_main at gmain.c:5028
#6  0x6acb9d29 in g_thread_proxy at gthread.c:797
#7  0x610ffe1a in pthread::thread_init_wrapper(void*)@4 at 
cygwin/thread.cc:1947
#8  0x6108974c in thread_wrapper at cygwin/miscfuncs.cc:600

A full backtrace of all threads is attached.

2. There is sometimes a SIGSEGV in g_slist_remove (in the main thread), 
with an abbreviated backtrace like this:

#0  0x6acb06dc in g_slist_remove at gslist.c:418
#1  0x6ac951f8 in g_child_watch_finalize at gmain.c:4580
#2  0x6ac928fa in g_source_unref_internal at gmain.c:1825
#3  0x6ac929fc in g_source_unref at gmain.c:1870
#4  0x005b371e in init_process_emacs at process.c:7100
#5  0x004ee1fc in main at emacs.c:1471

Again, a full backtrace of all threads is attached.

I don't know enough about glib to do much with this.  Jan or Paul, can 
you help?  Jan, if you want to install my unoptimized build of glib with 
debugging symbols, you can get it from my personal Cygwin repository:

   http://sanibeltranquility.com/cygwin/

There are instructions on that page.  You would need to install 
glib2.0-debuginfo, libglib2.0-devel, and libglib2.0_0.  You also need 
cygwin-debuginfo (from a regular Cygwin mirror).

The second trace suggests there's a race condition bug in Cygwin glib,
which I've tried to work around in trunk bzr 113138.  Does that help?
(At least, does it make Emacs crash more reliably?....)

As Angelo said, the answer to both questions is "No".  But there's 
actually a big difference.  First, the 'abort' breakpoint is never hit. 
  Second, there are no more SEGVs reported in glib.  There are lots of 
SEGVs in _malloc_internal_nolock, and some further SEGVs that gdb can't 
pinpoint.  I think all of the crashes in _malloc_internal_nolock are 
coming when it's called by special_realloc.  Maybe the latter needs to 
be calling _malloc_internal instead of _malloc_inernal_nolock.  I don't 
have any more time right now, but I'll try that later.

Ken

If the crashes in gmalloc don't happen unless glib is linked in, then
it's possible that its memory management conflicts in some way with
gmalloc (and possibly ralloc, if Cygwin uses that as well).

Thanks, I think that's the problem: the new code invokes glib
primitives before the memory allocator is set up on Cygwin, which is a
no-no.  I moved the glib SIGCHLD tickling to later, in trunk bzr 113142;
does that help?

No. Rev. 113146 fails in similar manner:

GLib (gthread-posix.c): Unexpected error from C library during 
'pthread_setspecific': Invalid argument.  Aborting.
Makefile:232: recipe for target `compile-onefile' failed

Ciao,

Sometimes the bootstrap hangs:

[...]
make[3]: ingresso nella directory "work/emacs/Work/lisp"
Compiling work/emacs/src/../lisp/emacs-lisp/map-ynp.el
make[3]: uscita dalla directory "work/emacs/Work/lisp"
make[3]: ingresso nella directory "work/emacs/Work/lisp"
Compiling work/emacs/src/../lisp/cus-start.el
WAIT WAIT WAIT...
IT HANGS

and I cannot break it with CTRL-C. To kill the "bootstrap-emacs" process 
I need to kill it with Windows task manager. The Cygwin "kill -9..." 
command doesn't help... it helps only to kill some "make" processes...

When it hangs, try attaching GDB to Emacs, and if that succeeds, show
a backtrace from all the threads ("thread apply all bt").

That fixed it for me.  I just ran two consecutive bootstraps without a 
problem.  Angelo, can you confirm?

Thanks, Paul.

One question: Can you explain why you think there's a race condition bug 
in Cygwin glib?  I should probably report this to the Cygwin glib 
maintainer, but I need to understand it first.

Ken

It clearly has that feel.  The problem is that if one does this:

  g_source_unref (g_child_watch_source_new (getpid ());

at the obvious spot in Emacs startup, just as glib is
spinning worker threads that do stuff, Emacs goes
kaflooey.  But if one waits until the worker threads
have stabilized (which is what the latest patch does),
it's OK.

It could be a bug in Emacs too.  Emacs's memory allocator
isn't thread-safe, right?  And glib uses threads.  Which
memory allocator is the Cygwin port using, exactly?  If
it's using Emacs's allocator (i.e., compiling gmalloc.c),
that's a bug in Emacs.  If it's using Cygwin's, it's more
likely a bug either in the Cygwin allocator or in glib.

The Cygwin port uses Emacs's allocator.

I just looked at Emacs's allocator, and I was wrong:
it tries to be thread-safe, if HAVE_PTHREAD is defined.
Is it defined on Cygwin?  If not, that's a bug; if so,
possibly there is still an incompatibility between
Cygwin threading and Emacs's allocator, but it'll
require some Cygwin expertise to debug.

At any rate *this* bug is now fixed, so I'm marking it
as done.  If the Cygwin port has strange memory-related
problems in the future, you might try the following patch (not
that it's necessarily the right thing...).

Yes, HAVE_PTHREAD is defined on Cygwin.

I've tried this, but it doesn't work.  I would be glad to switch to 
Cygwin's malloc if I could, but I haven't been able to figure out how.  See

I would say: No.

3 times the build was completed and the last it failed.

In each case, the build log shows errors.

Ouch.  As it happens I didn't successfully mark the
bug as "done", as I thought, so it's still live.

Please try commenting out this line in src/process.c.

    g_source_unref (source);

And if that doesn't work, please try commenting out
the previous line as well:

    GSource *source = g_child_watch_source_new (getpid ());

My experience is the same.  Thanks for the reminder that it's necessary 
to check the build log for error messages, even when the build appears 
to complete successfully.

Question for Paul: I'm trying to understand the code that led to this 
problem in the first place, and I'm puzzled by the asymmetry between 
block_child_signal and unblock_child_signal.  The first blocks SIGCHLD, 
while the second unblocks *all* signals.  Why is this the right thing to do?

Ken

I didn't write that code, but here's my guess.
Emacs normally runs with all signals unblocked.
Unblocking everything is the right thing to do,
if there's a bug elsewhere in Emacs that inadvertently
leaves signals blocked.

According to 'bzr log', you introduced those two functions in rev 111081.

I still don't get the asymmetry.  By your reasoning, it would seem that 
block_child_signal should set the mask so that only SIGCHLD is blocked. 
  And can unblock_child_signal really be sure that there's no good 
reason for a signal to be blocked?

But I don't want to belabor this.  You know much more about this than I 
do, so if you're sure the existing code is right, I'll drop it.

Yes, but if I recall correctly they refactored existing
code.  Existing practice in Emacs is inconsistent: sometimes it
unblocks everything, sometimes it reestablishes
the old mask.  As far as I know the difference
never matters, so either is "right".

OK, thanks, as trunk bzr 113206 I installed a change
to skip the gnulib tickling on Cygwin.

Although this should fix the bootstrap failure, I expect that
this reintroduces a bug into Cygwin Emacs, namely,
Emacs can sometimes lose track of subprocesses and/or kill off
unrelated processes; see Bug#12980 and Bug#8855.
Fixing this will require someone with access to Cygwin
and knowledge of how to debug threads under Cygwin,
neither of which I have.  Since the issue appears only
under Cygwin it could well be a Cygwin bug rather than an
Emacs or glib bug.

In more than six months, only one or two times Emacs, from trunk, closed 
unexpectedly. Usually it is enough stable.

Just a note I forgot before...


I think the best way to start in fixing/clarifying this issue is to 
reproduce it with a simple test case in plain C.

In that case, Cygwin guys will know how to fix it or could clarify what 
is wrong etc.

Another alternative is to replace

     if (! noninteractive || initialized)

by

     if (! noninteractive)

at least on Cygwin.  That allows the bootstrap to complete without 
errors.  Assuming this doesn't cause other problems, we wouldn't have to 
worry about reintroducing bugs into (interactive) Cygwin Emacs.

The remaining bug won't cause Cygwin Emacs to close unexpectedly.
What it'll do, is cause Cygwin Emacs to lose track of
its child processes -- it'll think they've finished,
when they haven't, or vice versa.  And it can cause
Cygwin Emacs to kill innocent-bystander processes.
These problems are rare, but I expect they can occur
under Cygwin, just as they used to occur under
POSIXish sytems before we redid child process handling.

I'm dubious about this proposal.

If there's an obscure race-condition bug during bootstrapping
that makes Emacs crash, why isn't it plausible that a similar
bug could occur during normal operation?  Bootstrapping is
a more-intense activity that could well be more likely to
trigger races, but isn't it more plausible that the races
could occur at any time?

I don't know, because I don't know when the race during bootstrapping 
was happening.  If it was happening when emacs was doing the tickling 
(in init_process_emacs), then my suggested change could conceivably 
cause emacs to crash immediately after startup.  Assuming this doesn't 
happen often, I think it's better than having bugs in subprocess handling.

On the other hand, if the race happens when emacs *executes* the glib 
handler (stored in lib_child_handler), then I agree with you that my 
proposal is unacceptable.

I would suggest that we try my proposal but leave the bug open while we 
see how it works.  If people start seeing random crashes, then we'll 
know it was a bad idea and we can revert it.

Just for completeness...

I have bootstrapped r. 113214 with Ken's patch. Emacs has been build 
fine, no errors. I have installed it and after 3 hours it is still 
running...

I would adopt Ken's idea and ping people to use/bootstrap trunk... Let's 
see if we can catch Mobydick...


Ciao,
  Angelo.

I have always to change manually it in bug-gnu-emacs@gnu.org...)

I've done some further testing [*] and determined that the bootstrap failures always occur as a result of the tickling, as I had hoped.  This should mean that, if my patch is applied, the only problem will be a possible random crash right after emacs is started.  The only question is how often this will happen in practice.  I think we can only determine this by applying the patch and asking users to test it.

Last night I began running a loop in which emacs (patched as I proposed)

hasn't been a single failure after more than 1300 iterations.  I don't

Glib got tickled.)

If no one objects, I'll go ahead and apply my patch later today.

Regarding this:

http://lists.gnu.org/archive/html/bug-gnu-emacs/2013-06/msg00963.html


shouldn't it flagged, in some manner, to Cygwin ("Creators") list? For 
example,

"Bootstrapping Emacs with this patch fails on Cygwin so and so... but 
not on GNU/Linux... Have you some idea?..."

After all, trying to bootstrap Emacs trunk is not so much work... The 
big work, perhaps, is in understanding the failure, I think..

Yes, I agree in principle, but I'm not yet sure it's a Cygwin bug, and I 
haven't been able to come up with a simple test case that exhibits the 
problem.  My naive attempt didn't work:

[Sorry, I accidentally sent an unfinished reply.  I'll restart.]

Yes, I agree in principle, but I'm not yet sure it's a Cygwin bug, and I 
haven't been able to come up with a simple test case that exhibits the 
problem.  My naive attempt didn't work: I wrote a little C program that 
tickled Glib exactly as in process.c.  I ran it thousands of times 
without an error.  So I have to try to figure out what's different 
during bootstrapping.  And Emacs's gmalloc.c may be part or all of the 
problem too.  That's not compiled on GNU/Linux.

I'd like to keep trying to track this down for a while before asking on 
the Cygwin list.

I wouldn't expect your test case to exercise the bug.
The bug occurs when Gtk or Glib activity is occurring
in some other thread at the same time that Emacs is
running.  To reproduce the bug, one must have a
race condition like that.  In your test case Emacs
is idle, so it's unlikely to exhibit the bug.

A couple more things.  Since the bug comes into play
only when glib is tickled, shouldn't the Cygwin case
suppress only the tickling, not the catching of child
signals?

Also, wouldn't it be better to give Cygwin maintainers
an easy way to reproduce the bug, say by compiling
with a special flag?

So, how about the following patch instead?

Yes, this looks good.  Please go ahead and apply it.

If it turns out that this really is a Cygwin/Glib bug (and not, say, a 
bug in gmalloc.c), it will be much easier to find the problem if I can 
provide the Cygwin maintainers with a test case in C, independent of 
Emacs.  Is there a simple way to simulate the kind of race condition 
that you think is going on here?

Thanks.

Ken

It looks a nice solution. I have applied the patch and bootstrapped with

   CFLAGS=-DTICKLE_GLIB_BUGFIX ./my_build.sh

and it fails as expected. Instead the bootstrap

   ./my_build.sh

is completed just fine.

This way Cygwin gurus have a possibility to catch Mobydick, if it exists...


Ciao,
  Angelo.

I found the bug.  It's that malloc_enable_thread doesn't get called in 
batch mode, because of the following in emacs.c:

#if defined (HAVE_PTHREAD) && !defined (SYSTEM_MALLOC) && !defined 
(DOUG_LEA_MALLOC)
   if (! noninteractive)
     {
       extern void malloc_enable_thread (void);

       malloc_enable_thread ();
     }
#endif

Removing " if (! noninteractive)" solves the problem.  Will it break 
something else?  I have no idea why malloc_enable_thread was only being 
called in the interactive case.

I don't see why it would.  I installed that as part of trunk bzr 113247,
and thanks for finding the underlying fault.

It seems that Mobydick has been catched! Rev. 113247 bootstraps OB... :-)

Many many thanks, too!

However, there is still a problem that got to arise recently.
Though I feel like the frequency got decreased.  That is that
Cygwin Emacs sometimes freezes for a couple of ten seconds
unexpectedly.  It happens irregularly while I'm writing something.
I'm not sure it is concerned to, but some asynchronous processes
are running at that time; though I don't believe that my keystroke
for self-insert-command triggers a communication with one of them.
Those are display-time (a timer) and ispell (and ndtp and Sj3).

In addition, how about Bug#14553 ?

Also this sometimes happens:

Memory exhausted--use C-x s then exit and restart Emacs
Error running timer `display-time-event-handler': (error "Memory exhausted--use C-x s then exit and restart Emacs")
Memory exhausted--use C-x s then exit and restart Emacs [3 times]

At that time I can do neither `C-x s' nor exit; what I can do
then is only to kill the Emacs process (so I transcribed the above
messages by hand).  AFAICR, it didn't happen until Jun 2013.

Please make a new bug report about this problem.  AFAIK, it has nothing 
to do with the present bug.  And it would help greatly if you could find 
the first bzr revision that exhibits the problem.

I'll take a look when I get a chance.

Hi,

This sometimes happens on Cygwin since the beginning of Jun
concurrently with Bug#14569 (bootstrap fails on Cygwin):

Memory exhausted--use C-x s then exit and restart Emacs
Error running timer `display-time-event-handler': (error "Memory exhausted--use C-x s then exit and restart Emacs")
Memory exhausted--use C-x s then exit and restart Emacs [3 times]

At that time I can do neither `C-x s' nor exit; what I can do
then is only to kill the Emacs process (so I transcribed the above
messages by hand).

Thanks.

Hmm.. I never have seen that..

Where you see those messages? May you give a recipe to reproduce them?

Here Emacs trunk works... Usaually I start it with at least 11 buffers, 
a single frame and 3 windows.. it runs for hours with no problem.


Ciao,
Angelo.

We've since found the cause of that bug, and it affected only 
noninteractive uses of emacs.  So I don't think there's any connection 
between that bug and this one.

Angelo already asked for a recipe to reproduce the problem.  I realize 
that may be difficult if the problem is intermittent.  If you can't do 
that, then it would really help if you could pin down the exact bzr 
revision at which the problem first occurred.

It (bug#14569) started in the morning of 06 June, 2013 (in Japan).
I'm building bzr Emacs every morning of week days, so the suspected
revision will possibly be one of these:

revno: 112865
timestamp: Wed 2013-06-05 23:45:34 +0300 (Thu Jun  6 05:45:34 2013 +0900)

I suspected it might be due to display-time-interval that was too
short (1), and turned back it to the default (60) about a month ago.
It didn't help after all, though.  Here is my Emacs clock setting:

(setq display-time-default-load-average nil
      display-time-24hr-format t)
;;(setq display-time-interval 1
;;      display-time-format "%H:%M:%S")
(display-time-mode 1)

> Where you see those messages? May you give a recipe to reproduce them?

It happens unexpectedly when I do something on Emacs, so I cannot
show a reproducible recipe.  But the frequency of this is much
less than the following:

Message-ID: <b4mfvvx66ut.fsf@jpl.org>
> Cygwin Emacs sometimes freezes for a couple of ten seconds
> unexpectedly.  It happens irregularly while I'm writing something.

Actually while I was writing this mail, "Memory exhausted" happened
only once, but the freezing happened for over ten times. :<

I'm encouraged with you and the active users anyway.  Thanks.

In a different bug report you mentioned that you configure with the 
following options:

--with-x-toolkit=lucid --without-imagemagick --without-dbus 
--without-gconf --without-gsettings

Superficially it would seem that there's no reason for your build to 
link with glib.  But obviously it does link with glib, or else bug#14569 
wouldn't have affected you.  My guess is that revno 112830 on June 3, 
which introduced gfilenotify, is what caused your build to link with 
glib.  Is it possible that gfilenotify doesn't work well with the lucid 
toolkit?  Or perhaps the tickling of glib causes problems when the lucid 
toolkit is used?

Michael and Paul, do you have any ideas here?

Ken

It's possible, but lucid isn't multithreaded.

What happens if you append --without-file-notification
to the 'configure' options?  I expect that's what's
dragging in glib.

Do you use autorevert? This would trigger gfilenotify, which has been
added June 3rd.

Best regards, Michael.

I tried --without-file-notification.  AFAICT no difference presents,
if anything, I feel like the frequency of the freezing is increased.
Emacs links cygglib-2.0-0.dll .

What if you also add --without-rsvg?

Oh, Emacs was built without glib.  It still sometimes freezes,
though I haven't seen "Memory exhausted" yet so far.  I'll keep
trying it.  Thanks.

Hi,

I tried bzr revision r113270 on my FreeBSD 9.1-RELEASE (amd64), and it
segfaulted during bootstrap process, (the compilation of files in "lisp"
directory). It generated a core-file lisp/bootstrap-emacs.core which has more
than 3-million (that's when I lost patience) recurring stack frames like
following:

#v+

This is no doubt fallout from trunk bzr 113247, needed for
Cygwin.  I installed what I hope fixes the problem for
FreeBSD, without reintroducing the Cygwin bug, as trunk
bzr 113275; please give it a try.

I don't use either Cygwin or FreeBSD, so I'm afraid
I have to rely on others to check these fixes.

Cygwin still bootstraps OK after this change.

It didn't fix for me. And this time I ran compilation with "memoryuse" limit set
to 128M and "vmemorysize" limit set to 512M, and back trace is not so helpful:

OK, please try again, with trunk bzr 113278.
Again, I can't easily test this on either Cygwin or FreeBSD.

Also, please don't CC: to emacs-devel@gnu.org, as this
is just a bug and is not worth bothering all Emacs developers
about.  CC:ing to 14569@debbugs.gnu.org should suffice.

Thanks Paul!

The emacs-24 branch builds correctly on FreeBSD 10.0-CURRENT here.  So I
just pulled your commit from the trunk ofr the Git repository and tried
a local build again from this revision:

  $ git ll -1
  5da8d1b - (HEAD, origin/trunk, trunk) Try again to fix FreeBSD bug re multithreaded memory alloc. (3 hours ago) <Paul Eggert>

with the following options:

    ./configure --prefix=/opt/gnu --without-x

This compiled Emacs successfully on FreeBSD, and resulted in the
following output from configure:

   Configured for `amd64-unknown-freebsd10.0'.

r113278 compiles fine on 9.1-RELEASE (amd64), and sending this email from
r113284.

Sorry.

I'm closing these two bugs:

bug#14569: 24.3.50; bootstrap fails on Cygwin
bug#14766: 24.3.50; sometimes "Memory exhausted" on Cygwin

I don't know why, sorry, but Emacs on Cygwin doesn't make the memory
exhausted, it doesn't freeze, and it bootstraps smoothly these days.
`system-configuration-options' I use now is:
	"--verbose --with-x-toolkit=lucid --without-imagemagick\
	--without-dbus --without-gconf --without-gsettings"
I.e., Emacs is built with glib.

Thanks.

As for the derived bug
"Emacs segfaulting on FreeBSD 9.1-RELEASE (amd64) during memory allocation."
that is labeled with bug#14569 (the same), I believe it's been solved:
