Windows Emacs (built from r110828) was idle for a few minutes while I made a
coffee. On returning, emacs was completely unresponsive and redisplay
was not drawing anything.
Windows XP SP3
MinGW gcc 4.7.2

If this recurs, maybe try bisecting to find the problematic commit.
Do you know what was the previous revision which you used?
Also, how was Emacs unresponsive -- did it consume any CPU cycles at
all? Were all the threads locked up, or just some? If you detach
from it, then attach again, do you see exactly the same backtrace?

This looks like the input thread is waiting for GetMessageW to return,
which is normal -- it means there's no input, and we are waiting for
it.

This is the main thread, but its backtrace looks like the stack is
smashed, and real_itimer is a variable, not a function.
We need more data points on this.

I rebuild emacs every day from trunk, but only do a full bootstrap when
necessary. I have updated the Mingw compiler this week though, so that could
be an issue. I'll try bisecting (and downgrading the compiler) if I see this
again.

Emacs was not consuming any cycles - the system was completely idle.

I'll see if this is reproduceable and try to get more info.

Was the build optimized? (I'm guessing not, but I want to be sure.)

OK. Any idea why you had so many threads? Normally, Emacs 24.3.50
should have only 3: the main thread, the input thread, and a thread
that runs atimers (Emacs arranges for a timer to fire every 2 seconds,
to check whether any new input has arrived.) Yet another thread, the
4th one, is automatically started by the OS when you attach a debugger
to Emacs, and this is it:
Thread 6 (Thread 8744.0x2080):
#0 0x7c90120f in ntdll!DbgUiConnectToDbg () from C:\WINDOWS\system32\ntdll.dll

#1 0x7c952119 in ntdll!KiIntSystemCall () from C:\WINDOWS\system32\ntdll.dll
No symbol table info available.
But what are the other 2 threads you have, namely:

One of them appears to be reading something, the other is waiting for
some event. Did you have some subprocess running or some network
connection active at that time? Or maybe your routine operation has
some subprocesses (a speller, perhaps?) and/or network connections
active?

system-configuration-options includes --no-opt, so unoptimized.

I have some files open via tramp (pscp method) on another machine. This uses
putty for ssh (plink.exe) and scp (pscp.exe) for file tranfers. At the time of
the lockup, emacs had a CMD.EXE subprocess running plink.exe.

Thanks. I wanted to know this to try to reproduce the lockup here. I
will try that as soon as the problem with crashes on Windows is
resolved.

The latest trunk is up and running for more than 3 hours with no
problems. I have a shell buffer running plink and a remote file
fetched with pscp. I also have display-time active.
Any other features you have on that could trigger periodic processing
of any kind?

I have seen this once again, after doing a full bootstrap from tip this
morning to ensure I wasn't seeing artifacts of a broken build. It seems to
happen about once a day.

Not that I know of. The emacs-server is running, but I not used anything that
connects to it, so it should be doing anything. I do use gnus to read news,
but quit gnus after I've read some groups (the lockup was several hours later).
The compiler update may be at issue, so I'll try downgrading back to MinGW gcc
4.7.0 and doing a full bootstrap.
Anything else I should look for in gdb ?

That's a good idea.

Try continuing the other threads, and see if they are all stuck, or
just the main one. I think the command is "thread NUMBER continue".
Also, looking at the threads in the Process Explorer should tell if
they are alive or locked up.

> Fabrice, what bzr revision did you compile
I did not compile it myself. I took a version compiled (on 22 October) by Dani
Moncayo, downloaded from https://www.dropbox.com/sh/7jr3vbv9tm1zod0/jPuvfrJAe8.
However, eval'ing emacs-bzr-version returns:
"110618 monnier-CRDzTM1onBSWkKpYnGOUKhc95p6a78TbeXGMcDWol4xM7RDeeHvltMWNcNhuwuIV@public.gmane.org"
> and with what version of GCC?
No idea, sorry...
Does his recipe
(https://www.dropbox.com/sh/7jr3vbv9tm1zod0/qpjXONObVR/emacs-build-recipe.txt)
give you valuable information?

That build was from revno 110618 (2012-10-22), so the GCC version
should be 4.7.0, since MinGW didn't upgrade to 4.7.2 until 2012-11-05.
(My builds thereafter were with GCC 4.7.2)

Thanks. Andrew used 4.7.0 before the crashes, so I don't think the
compiler version is an issue.

Correct - I've done a clean bootstrap using 4.7.0, and I see this problem on
both trunk and emacs-24 branches.
Looking emacs-24 (r110863) with Process Explorer:
212412 emacs.exe+0x32291 State: Wait:DelayExecution
212616 emacs.exe+0x148efe State: Wait:Suspended
212604 emacs.exe+0x142350 State: Wait:WrUserRequest
236140 RPCRT4.dll!ThreadStartRoutine State: Wait:WrQueue
I tried suspending and then resuming each thread in turn from Process
Explorer. Resuming thread 212604 unblocked emacs and it started working again.

Was that the only thread whose resumption unlocks Emacs? If so, can
you find out what thread was that? Process Explorer can show that
call-stack, and you should be able to find out what functions were
referenced by using the "info line" command inside GDB. Like this:
(gdb) info line *0x11c3d40
Line 863 of "sysdep.c" starts at address 0x11c3d40 <init_sys_modes+7>
and ends at 0x11c3d4a <init_sys_modes+17>.
(Note the asterisk before the address.)
WrUserRequest seems to indicate that the thread was suspended by the
application itself, which would point the blaming finger at my
implementation of SIGALRM (see w32proc.c), whereby when the timer
expires, the thread which runs the timer code suspends the main
thread, invokes the signal handler, and then resumes the main thread.
If my guess is correct, this would mean that the thread whose state is
WrUserRequest is the main (a.k.a. "Lisp") thread.
Another possibility is that this is the input thread, the one that
calls GetMessage. But then I don't understand why it is blocked
forever until manually resumed. Hmm...
If you attach GDB, do you again see garbled backtrace, like in the
original report? Or do you see something more informative?

I tried to get call stacks from process Explorer, but that made it die :-(
The fatc that thread 236140 is at ThreadStartRoutine makes me wonder if this
is related to the perils of DllMain (i.e. the loader lock).

Sorry, I don't have the original process running any more - it's hard to get
anything done with an unresponsive app of the screen. I'll try to dig out more
info the next time I get a lockup.
The one thing that does seem completely consistent is that the lockup happens
after several minutes of being idle (i.e. no keyboard or mouse input).

Sorry, I don't follow. Can you say more about this problem, or point
me to some accessible documentation about it?

The DllMain notifications for process and thread create/destroy are called
with the (system internal) loader lock held. This means that anything called
from these routines should not use locks, or deadlock is possible. So I was
wondering if the thread manipulation for timer handling is interacting with
those mechanisms.
Of course I don't know nearly enough about Win32 to actually say much useful
here, so the actual problem is probably something else entirely.

Thanks for the explanation.

Don't assume I know more than you do ;-)
Anyway, I actually don't understand why some thread is at
ThreadStartRoutine, if that fact really means that a thread is being
created. The timer thread is created during startup, and is not shut
down until Emacs shuts down. And we don't create any other threads in
the middle of a session (unless the user invokes profiler).
So the only way I can understand this ThreadStartRoutine business is
that somehow the timer thread exited due to an error (look for a line
saying "return 2;" in timer_loop), and then the next time Emacs sets
up the 2-sec atimer, a new thread will be started.
So could you please set a breakpoint at line 575 in w32proc.c, which
is this:
/* Start a new thread. */
itimer->terminate = 0;
itimer->type = which; <<<<<<<<<<<<<<<<<<<<<<<<<<<
run Emacs under GDB, and see if this breakpoint breaks more than once
when you run Emacs as usual? It should break one time during startup,
and never thereafter. To make sure you don't disrupt the timers,
define commands for this breakpoint that simply continue, like this:
(gdb) break w32proc.c:575
(gdb) commands
> continue

I applied this to emacs-24 branch (r110866) this morning. So far I've not seen
a lockup, but I'll to run it for a day or two to be sure.

After longer uptime, it seems this patch is not successful. I haven't had a
complete lockup, but I have seen a couple of glitches where it froze but then
recovered a short while later.
The unfreeze may have been due to capturing a stack trace with Process
Explorer (I have upgraded to the latest version which is less buggy).
The patched emacs-24 does seem to leak handles: at the moment Process Explorer
report that emacs has 50805 handles in all, most of which are thread handles.
The number of handles seems to increase at a rate of 2 to 4 per second.

I have no time to build Emacs now and have not had it for a very long
time. However I have seen Emacs freeze a lot of times when it is idle.
This started to get more common when I moved to a 64-bit windows 7
(from windows xp, 32-bit).
I have always thought that this must be bad handling of the messages
from the operating systems, but I have had no chance to pin this down.
Reading here I wonder if data are accessed somewhere in a system time
thread without critical section handling.

OK, that was a stab in the dark anyway.
I found a few problems in the code and fixed them in revision 110867
on the emacs-24 branch. Please try the latest branch (without the
patch) and see if the problem persists.

Yes, that's one of the problems I fixed in r110867. Shame on me.
(I think the fact that the handle to the caller thread was constantly
modified could be the reason for the lockup, if the change happened
between SuspendThread and ResumeThread calls.)

Those incidents are most probably unrelated to the issue discussed in
this bug, because the timer thread was introduced into Emacs only very
recently, it does not exist in Emacs 24.2 and earlier.

That is so vague I cannot even begin thinking about what you have in
mind.
In any case, what Andrew reported looks like some thread is suspended
_while_ it holds a critical section. So, if anything, this is not
about lack of critical sections usage.

I am not sure of that ;-)
What is suspending the thread? Should it be able to do that?

When we have fixed the bug, we will know.

I've been running an (unpatched) emacs-24 r110867 build for a few hours, and
so far it seems to be behaving well. I'll report back after a longer run to
see if the lockup can be still be reproduced.

I rebuilt emacs-24 at r110874 this morning, and have not seen any freezes or
lockups all day. I think this bug can now be closed.
Thanks,
