bug#13546: 24.2.92; Error(s) when sending emails

[Sebastien Vauban]

Hello,
For some unknown reason, at some point in time, I've got an error when sending
emails -- the same way I do for ~ 8 years now:

--8<---------------cut here---------------start------------->8---
network-stream-open-starttls: make client process failed: no error, :name, smtpmail, :buffer, *trace of SMTP session to mail.missioncriticalit.com*, :host, mail.missioncriticalit.com, :service, 25
Saving file d:/Users/sva/.gnus.d/drafts/drafts/2...
Mark set
basic-save-buffer-2: IO error writing d:/Users/sva/.gnus.d/drafts/drafts/2: Socket operation on non-socket
Saving file d:/Users/sva/.gnus.d/drafts/drafts/2...
--8<---------------cut here---------------end--------------->8---

This phenomenon is really new to me, but I can't tell its source:

- because of the pretest Emacs version?
- because of my new environment (new laptop with Windows 8)?
- because I'm using constantly the sleep mode of the laptop?
- ...

And, what's even more surprising, is the second error: when wanting to save a
draft copy of the email (as I couldn't send it), with C-c C-d, I've got the
error:

--8<---------------cut here---------------start------------->8---
basic-save-buffer-2: IO error writing d:/Users/sva/.gnus.d/drafts/drafts/2: Socket operation on non-socket
--8<---------------cut here---------------end--------------->8---

Is this all repeatable, or did it happen just once?

Unluckily, it already happened a couple of times (3 or 4 times) over the last
week (since I have version 24.2.92, IIRC -- not sure, though).

Every time, I quitted Emacs and restarted it.

Hi,

You seem to be posting via the bug newsgroup. Please don't do that,
since it breaks http://debbugs.gnu.org/13546 - notice none of your
replies are there. This is unfixable, so please treat the bug newsgroup
as read-only (better still, forget it exists).

The problem is that sometimes the bug tracker doesn't respond with the
bug number for very long time.  To someone like me, who is used to
reply without ever looking at the headers, it's a nuisance to check
whether there's a bug address there, and if not, go through the PITA
of surfing to the tracker and searching for the bug number there.

I'm not sure what you are saying. Are you saying this is why some people
want to use the newsgroup interface? If so, that doesn't make sense to
me.

There is no problem with what you were doing in your replies (note that
I was talking to the OP, not you; check the To: header).

It is impossible for a message to appear on bug-gnu-emacs without a bug
number UNLESS the initial report was sent by the newsgroup (which it
wasn't in this case).


(Anyway this is OT for this report.)

I posted the bug via `M-x report-emacs-bug'. Then, I got replies from Eli, and
answered them by "following up" (F) from the posting read in the newsgroup.

If you want me to "wide" reply to the authors (S W), I'll do that next time.

But I don't have the impression that postings are missing from the Web link.

> (Anyway this is OT for this report.)

FYI (Eli), I don't have that anymore since going back on Emacs 24.2.91 for a
couple of days. I'll now go back to using 24.2.92 and see if I got it
reproduced.

  Seb

I'm not sure what S W does; but basically always reply by mail, never by
usenet. Thanks!

FYI, the _first_ time I press `C-c C-d', I get the above. The second time, not
anymore, and the draft is correctly saved: I quit Emacs, restart it, and send
straight away my email.

Sorry, I don't understand: is the "second time" in the same Emacs
session, or after restarting?  If the former, does the draft get saved
to the same file d:/Users/sva/.gnus.d/drafts/drafts/2 as in the first
attempt?  Also, does "first time" mean first time after the laptop
awakes from sleep mode?  If so, can you wait a little longer before
you try this, perhaps the disk did not yet have chance to spin up.

In any case, I'm sure that the "Socket operation on non-socket" part
is a red herring: write-region is not careful to zero out errno before
the operations it wants to diagnose, so the value is probably coming
from some entirely irrelevant interim error.  What is important is
that write-region _does_ fail in one of these operations, the question
is which one?

Sorry for not being clear the first time ;-)

Let's recap:

1. The sending error occurs (and reoccurs again and again if I try to resend
   the email)
2. I'm trying to save the mail as a draft (C-c C-d): IO error above
3. I'm retring to save it once again ("second" time), with no other change:
   draft is successfully saved
4. I'm restarting Emacs
5. I'm sending the precited email

Note -- Looking at the location of the drafts, I'm puzzled that the draft is
saved in `~/.gnus.d/drafts' (that is, under my `gnus-directory'), and not in
`~/Mail/drafts' (that is, under my `message-directory'). I though that
everything related to "email composing" would be handled by Message?

The problem occurs for example just now, while my laptop is up since this
midday. So, it's not 1just a few seconds or so after making the laptop alive
-- BTW, my new laptop (Asus Zenbook UX31) is 100% SSD, so I guess it can't be
more speedy than it is.

Why did I mention that fact, then?  Because, before, with the old laptop, I
quitted Emacs much more often -- at least once every evening. Now, I'm more or
less used to let Emacs (and the laptop) sleep between work sessions.

I cannot reproduce yet the problem, as I still don't have a clue about the
conditions which are necessary to do so.

Any test I could do when this does happen?

Btw, it could be a real problem with sys_close on Windows as well.

What I'd like is for you to step with a debugger through the affected
code and see what is going on there.  But since your cannot reproduce
this at will, it doesn't seem to be possible...

You mean with gdb, like I do when Emacs is hanging or crashing?

But I'm sure it will come back[1], and that will happen, can you tell me what I
should type in the GDB window?

[1] Going back using 24.2.91 for a while to see if I get it there as well.

OK.  So please attach GDB to Emacs _before_ the problem happens, and
set a breakpoint like this:

  (gdb) break fileio.c:4913
  (gdb) continue

The breakpoint will be on this line in fileio.c:

  if (! ok)
    error ("IO error writing %s: %s", SDATA (filename),  <<<<<<<<<
           emacs_strerror (save_errno));

Then do whatever it takes to reproduce the problem.  When it happens
again, this breakpoint should break.  Then type the following GDB
commands:

  (gdb) p desc
  (gdb) p/x fd_info[N].flags

where N is the value of 'desc' as displayed by "p desc".  That's
assuming that value is non-negative; if it is negative, the second
command is not going to display anything useful.

Meanwhile, I installed a couple of small changes that may or may not
solve this problem, so please be sure to try the next pretest binary
when it becomes available.

Thanks.

It gives me something, but not what I expected.  Did you at all see
the "IO error writing FOO" message this time?  If not, the above
breakpoint will not break.

In any case, since you say the problem comes back after 2 hours of
usage, it is probably better to attach GDB and set the breakpoints at
the very beginning of your session.

To catch this message:

  warning: sys_read called when read is in progress

please put an additional breakpoint on line 6410 of w32.c, which says:

        DebPrint (("sys_read called when read is in progress\n"));

and when it breaks, please do:

  (gdb) p fd_info[fd]
  (gdb) p fd
  (gdb) p *cp

TIA

Not this time, no.

OK, I do this:

1. Launch Emacs 24.2.93

2. Go to c:\Program Files (x86)\Emacs-24.2.93\bin

3. Run: gdb -p 15276
   XXX not sure about having to reference emacs.exe?
   XXX or should I start somehow Emacs from GDB?

4. Type in GDB:
   (gdb) break fileio.c:4913
   (gdb) break w32.c:6410
   (gdb) continue

5. Wait for problems, and do what you wrote in these threads.

Is this correct?

Can we step back for a moment and talk about the "Emacs is unusable"
part?  What exactly stops working for you, that you need to start
another session?  For each command that fails at this stage, please
show the error message(s), if any, that are the manifestations of the
failures.

Also, when you cannot "connect to your email", whatever that means,
please press F12, or wait until some breakpoint breaks, and show me
the contents of these two arrays:

  (gdb) p fd_info[0]@64
  (gdb) p child_procs[0]@32

Thanks.

Examples of show-blockers:

- Helm-find-files does not include "locate" results anymore (I mean: from
  es.exe), just the current buffers, and the recent files.

- When connecting to my mail server, it's denied: I see all my mail groups
  grayed, and pressing ^, closing the server connection (C), re-establishing
  it (O) does not work. So, basically, I can't read my mails anymore.

Any error message(s)?  Or just silent failures?

Not necessarily, but they're what just popped out of my mind. I meant as well
that the list is maybe not exhaustive. But, when thinking more, no, I don't
see other problems.

Euh, sorry, another one: impossible to convert an Org file to PDF.

In fact, to be exact, these are problems which render Emacs unusable _for me_.
So, I quit, and take a new one: if I can't read my mails, easily access my
files and/or convert documents to PDF, well, I'm pretty blocked.

Silent failures -- at least, I never saw anything wrong. Maybe some info is
hidden, though, somewhere in Messages or in debug buffers?

Yes (see live screencasts): connections denied to the mail server. Tough,
that's not a that weird message... Nothing as spectacular as "spawning
processes" or such.

OK.  I really need to see those two arrays in this situation.  I think
they are key to understanding what might be going on.

I saw an error message saying "make client process failed".  Please be
sure to look in the *Messages* buffer and post here any similar error
messages, especially those related to failure to start processes, open
files or network streams, create pipes, etc.

Thanks.

I can imagine it can take you long to dissecate the logs I sent you, but I'm
at least curious to know if what I sent you is what you expected to receive
for your analysis -- or if you need other data from me?

Voilà, did everything you wanted me to do, I think.

I began working around 09:30, and problems appeared from 12:18, that is after
3 hours of normal Emacs use.

Problems (in order):

- Can't save file due to "Spawning child process: resource temporarily
  unavailable"
- Can't export Org file to PDF due to the same reason
- Can't read posts NNTP server
- Can close it and reopen it, but email server is now "denied"

Thanks, this was exactly what I needed.  Revisions 111267 and 111268
on the emacs-24 branch should take care of these problems.  Please try
the next binary from the emacs-24 branch, or the next 24.2.9x pretest,
whenever you can.

Many thanks for figuring this out. The merge I just did of this to trunk
wasn't completely smooth, so you may need to fix it there.

Sebastien, it would be great if you can find a way to try this before
the next pretest.

I'm willing to try whichever version you're interested in, but I need a binary
ready for me to use. It's impossible for me right now to go through all the
necessary tests to try and compile it myself under Windows 8 -- I clearly have
no such environment running on my laptop now.

If you can provide me with a link, or if Dani is ready to make another one,
it's easy for me to download it, and use it: I need Emacs to do all my work
(from writing documents to reading/writing emails), so the "use it" part is
not the trouble.

For the last months, my feeding place is Dani's Dropbox on
https://www.dropbox.com/sh/7jr3vbv9tm1zod0/jPuvfrJAe8.

Well, look, there are binaries from 1 to 2 hours ago:

- emacs-24-r111270-20130215-w32-i386.zip (58.94 MB), 1 hr ago
- emacs-trunk-r111788-20130215-w32-i386.zip (59.32 MB), 2 hrs ago

Which one do you want me to use?

Best regards,
  Seb

Check your inbox, I've sent you a screencast link (which I prefer to keep
private, for not exposing private stuff), but please know that version does
not work at all for my test case:

- using Helm: buffers shown, locate not displayed...

- creating or opening an Org file (I wanted to test the export but couldn't
  get that far: max-lisp-eval-depth problem!

- reading my emails with Gnus: server is inaccessible

Any error messages?  Anything in *Messages*?

That's got to be unrelated.  Does it help to enlarge
max-lisp-eval-depth?

> - reading my emails with Gnus: server is inaccessible

Is that right from the start?  If so, can you open any other network
connection, like fetch some URL with the url-retrieve?

Can you launch a process?  E.g., does this work, if evaluated in
*scratch*?

  (setq proc (start-process-shell-command
		"locate<0>" "locate-results<0>"
		"locate eee"))
  (sleep-for 20)
  (delete-process proc)

If you attach GDB, do you see any "warning" messages?

I'm at a loss here...  The changes don't affect any code that launches
subprocesses or open network streams.  They just affect what happens
when there are no more free slots for additional subprocesses, which
should only happen once you've launched at least 32 of them.  Can you
show the contents of child_procs[] array, like you did before, when
you cannot see the results of 'locate'?

Eli,

A quick one-minute answer on what I can, not being able to test right now (and
almost going to bed as well)...

Not that I saw, no.

Yes, but that could be related to a precondition to connect to my mail server:
decrypting my authinfo.gpg. If that fails (or doesn't succeed), the rest won't
work.

I clearly want to believe you, but did you see the live video: the difference
is quite impressive between what's possible in one process and what's not in
the other.

I hope to give you more details by tomorrow.

Meanwhile I think I found the bug.

I went ahead and reverted all the changes related to the subprocesses
which I made since the 24.2.91 pretest, which you say worked for you.
I don't want to hold the 24.3 release hostage by my evidently inept
tinkering with this code.  The problem I tried to avoid is minor (in
comparison with the breakage I caused by the "solution"), and is
already fixed on the trunk in a more fundamental way.  So I guess
Emacs on Windows will need to stay with this problem for a little bit
longer, until we deliver a release from the current trunk.

I hope the next binary you could try from the emacs-24 branch will
work again for you, and the pretest can then continue on its course.

Thanks.

I'm back from vacation, and can go on (helping you) debugging this.

I see on Dani's DropBox account those binaries:

- emacs-24-r111276-20130218-w32-i386.zip (58.94 MB), 7 days ago
- emacs-trunk-r111822-20130217-w32-i386.zip (59.33 MB), 8 days ago

IIUC, you want me to test the first one?

As said in a separate bug report, emacs-trunk has a problem opening Org files
(at least, for me) because of an autoload. Bastien should have fixed that.
I'll report when testing the next available binary.

Regarding emacs-24 (Emacs 24.2.93), I'm using it since yesterday morning. It
more or less causes me problems after a couple of hours.

The last symptom, now, was when trying to send an email via Gnus (or should I
say Message?). Emacs seemed inflooping, but still stopped and displayed me
this after a while (one minute or so -- subjective appreciation):

--8<---------------cut here---------------start------------->8---
Emergency (alloc): Warning: past 95% of memory limit
Memory exhausted--use C-x s then exit and restart Emacs
--8<---------------cut here---------------end--------------->8---

I did follow the advise...

Best regards,
  Seb

Please post here all the symptoms, not just the last one.  We don't
have much time till the next pretest (which is planned to be a release
candidate), so we must be very efficient in our communications if we
want any chance of solving this before Emacs 24.3 is released.

Do you still maintain that pretest 24.2.91 worked fine on this same
machine with the same setup?  If so, then I'm almost at the end of my
wits wrt your problems.  I have reviewed all the Windows specific
changes introduced between 24.2.91 and today, and found only one that
could be even remotely relevant.  I have now reverted that one change
(revision 111303 on the emacs-24 branch), so please see if the next
binary behaves better.  If not, I will have to give up on these
problems until someone more talented shows us the light.  Sorry.

Thanks for doing that. I don't think we have anyone more qualified than
you to look into this, so thanks for sticking with it. :)
Sorry I can't help, I know nothing about this.

(r111303 wasn't marked "do not merge", so it was merged to trunk.
If that wasn't right, please revert it there.)

Unfortunately, I don't have other symptoms to share with you. Except if you
tell me to look for some data when attaching GDB to the sick process.

I understand, but I don't see what I can add in this case.

Yes, I do. During a few days, I went back on 24.2.91, and did not see anything
wrong with it.

I just see there are 2 new binaries built by Dani:

- emacs-24-r111300-20130225-w32-i386.zip (58.94 MB), 9 hrs ago
- emacs-trunk-r111884-20130226-w32-i386.zip (59.41 MB), 7 hrs ago

Damn, your change is not there. IIUC, the next build done by Dani will be in a
week or so...

I don't understand: above you say that it "causes you problems after a
couple of hours".  Those problems must have _some_ symptoms, or else
you wouldn't have known there are problems, right?  So what did you
see?

I thought I gave the symptoms here above:

After a couple of hours (like 2 or 3), when I had composed an email and was
sending it (I had pressed C-c C-c), Emacs wrote "Sending email..." (or
similar) in the echo area. Normally, that message disappears after a couple of
seconds, and I'm back to the Group buffer.

Here, that message did not disappear. After 1 minute or so, I thought that
Emacs was hanging. I checked my Internet connection, that was OK.

But seconds later, Emacs still prompted me:

    Memory exhausted--use C-x s then exit and restart Emacs

in the echo area, and

    Emergency (alloc): Warning: past 95% of memory limit

in a popup buffer.

I went back to the draft of the email, and tried again, but the message never
got sent. So, I restarted Emacs as stated.

These are the symptoms that I observed. Do you expect anything else?

Clearly, I should have looked at the memory footprint of Emacs, but (for
reasons which escape me now), I unfortunately did not. But I thought that the
messages only would help you localizing the cause of the problem.

Best regards,
  Seb

The messages just say that Emacs is using up a lot of memory for some
reason.

Next time, please look at the memory footprint and also at the CPU
usage, and if the latter is high (meaning that Emacs is looping
somewhere), please attach the debugger and see where it is looping.

Indeed.  Most likely the memory is used by C-level objects rather than
by Elisp objects, but in case these are Elisp objects, you can install
memory-usage (available from GNU ELPA) and do M-x memory-usage when the
process's size is suspicious (assuming that at that point Emacs is
still sufficiently usable to run the above command).

Since this happens when sending email, i.e. opening network
connections, I suspect that memory might be eaten up by reader threads
we start to support each connection.  This is further exacerbated by
the fact that Sebastien uses TLS connections for email, so perhaps
emacs_gnutls_pull is part of the problem.

Sebastien, if the latest emacs-24 binary still gives you trouble,
please try separate the sub-process and Helm stuff from the email
stuff.  That is, start 2 sessions of Emacs: one that uses Helm, but
does not use email, the other that uses email, but not Helm (or
subprocess-related commands in general).  I'd like to know whether
none, one, or both of theses sessions will exhibit some abnormal
symptoms after several hours.

I read through this thread.

I am not aware of anyone else experiencing this bug on W32 or other
platforms.  May I also suggest running without the GnuTLS DLL, which
will degrade your experience but may give a good differential?  But
without at least one other confirmed case of this bug, it's really hard
to find a pattern that triggers it.

I didn't see this suggested: can you try from another platform besides W32?

Have you tried multiple versions of the GnuTLS DLL?

Unless you are thinking about a bug in GnuTLS, I don't see how this
could help.  The problem is quite clearly in the infrastructure used
in the w32 build of Emacs.  Any other platform will not have any
comparable infrastructure, as they all use system-provided facilities
like signals and pty's.

I'd like to know that there's a working Emacs and a broken one, so we
can do some differential analysis.  Right now we're crossing our
fingers that the latest pretest works.

Also, if we can determine definitely that the problem only affects W32
as we have supposed so far, it makes the debugging easier and the
problem less of a release blocker.

I brought up GnuTLS because it's involved in some of Sebastian's setup,
and it has special glue in Emacs for W32.  As with my other suggestions,
I'm just trying to do some differential analysis to see if there's some
kind of bisection that will reduce the set of possible causes.  But I
agree with you that it's an unlikely cause... so I'll be quiet now :)

The symptoms we saw up till now (see the discussions) all so
overwhelmingly point towards the w32-specific code that deals with
subprocesses and network connections that it is hard to believe
comparison with any other platform will be of any benefit whatsoever.

In any case, we already have a working Emacs (24.2.91) and a broken
one (24.2.92 and 24.2.93), so if you want to compare them, please do.

> Right now we're crossing our fingers that the latest pretest works.

_I_ am crossing fingers.  Because I see no changes between 24.2.91 and
the current emacs-24 branch that are specific to w32 and touch the
relevant areas of Emacs.  If the current release branch is still
buggy, I simply don't know what else could be the reason, and will
advise Glenn to proceed with the release candidate, this problem
notwithstanding.

No one else reported anything similar, not on Windows, not elsewhere.

I think that Eli is plain right. Moreover, Thierry, the maintainer of Helm
never had any problems such as mines with Helm and locate. On Windows, the set
of programs is different, and Eli tells pratical constraints are as well quite
different.

So, this clearly seems to be Win32-only, reason why, maybe, there are so few,
or I'm the only one, reports of this.

FWIW, I currently regard Emacs 24.2.93 (from file
emacs-24-r111307-20130227-w32-i386.zip) as being as good as the Emacs 24.2.91
I've been using for weeks.

I (think we can) trust this version to have fixed problems introduced in
24.2.92 and first versions of 24.2.93.

Best regards,
  Seb

I doubt anyone else who tracks development versions has such an
extreme setup, that puts such a pressure on the infrastructure used in
the w32 Emacs for supporting subprocesses and network connections (the
same infrastructure is used for both types).  As you must have seen in
one of the messages I posted and in the corresponding screencast, Helm
sometimes fires up an async subprocess for every keystroke, then kills
each one of them right away.  Emacs on Windows can only support up to
32 subprocess or up to 64 network connections (each subprocess
requires resources of 2 connections).  So any subtle problems and race
conditions in the related code, that will go unnoticed on more "quiet"
systems, could be exposed by such an enormous resource pressure.  This
is complicated by the fact that Sebastien uses the Cygwin Bash as the
sub-shell, so any subtle problems with controlling, communicating, and
killing such processes from a native w32 application might also come
into play here.

I don't think GnuTLS per se is the problem.  At most, it could be the
fact that emacs_gnutls_pull calls 'select', but I doubt even that.

Just to comment that this is not really the development version any
more; this is essentially Emacs 24.3. If not many people are pretesting
it, there's not much we can do. Or if people are testing it, but not
seeing this, it's not common.

To me, this doesn't seem a very sensible thing to do, but I've never
used Helm.

I don't know how long we keep waiting for this issue, which is 5 weeks
old at the moment. Possibly/probably even older, eg

http://lists.gnu.org/archive/html/help-gnu-emacs/2012-10/msg00021.html

http://debbugs.gnu.org/cgi/bugreport.cgi?bug=13701#11

http://debbugs.gnu.org/cgi/bugreport.cgi?bug=13701#14
   Problems began appearing with Emacs 24, IIRC.

Exactly the same issue in 24.1, AFAICS:
http://debbugs.gnu.org/cgi/bugreport.cgi?bug=12579#50

And in 24.2:
http://debbugs.gnu.org/cgi/bugreport.cgi?bug=12579#134

And in 24.2.50:
http://debbugs.gnu.org/cgi/bugreport.cgi?bug=12579#188

Report #12579 is 5 months old, and very long.


If we can't seem to make any progress in the next few days, I think all
we can do is add a PROBLEMS entry (which no-one will read of course),
and carry on with 24.3. But if people think that's a bad plan, we can
wait a bit more.

Given the latest report from Sebastien, there's hope that the current
emacs-24 branch is stable enough for a release.  I suggest to wait one
more day.

After one extra workday of normal Emacs use, I'm telling you:

    GNU Emacs 24.2.93.1 (i386-mingw-nt6.2.9200) of 2013-02-28 on VBOX-W7

is perfectly fine for my use case -- as was 24.2.91.

Done.

Not really.  The last change I made, which seemed to make the
difference, was not to reset the flags for file descriptors we use to
monitor output from subprocesses and from network connections, when
the file descriptor is open for a regular file.  But since the same
flags are reset when the descriptor is closed, I don't see how this
could make any difference.  The only thing that led me to this change
was that 24.2.91 didn't have that code snippet.

In this case, I can't: that's the only I found working (when setting Gnus)
when connecting to the company email server. The admin has suppressed less
secure accesses.

That's why, anyway, the proposition of Eli is good to distinguish about both
possible causes of the problem.

That is good news.  Is this with or without separating Gnus/email

That is, do the `finish' dance, right?

Thanks a lot for the warning -- I wouldn't have checked so early, otherwise.

Thanks.  I will leave this bug open in case there are leftovers.  (I
also am still looking at the gnutls part of this riddle.)

You might also try one of the trunk builds, as the trunk didn't have
that problem in the first place.

I'll be glad that all those problems will be behind us. I couldn't imagine
suffering more because of using the greatest magical piece of software I do
have at my fingertips...

OK. But note that I'll be out for a week, so don't expect problem reports from
me...

BTW, a couple of questions:

- What about that magical `C-v' character?  Any idea?

- Now that you know what the problem was, can you confirm that Emacs 23 did
  behave well for my use case?  Maybe Emacs 24.0 as well?

- Is the current problem only happening on Windows (or due to my shell
  setting)?

- Is it only with heavy process-creator users like me (by using Helm as my
  almost only way to switch between buffers and files)?

- Can you confirm the GDB command had to be "p *cp" and not "b *cp"?

Best regards,
  Seb

No idea.  It doesn't seem to be related to the problem, though.

> - Now that you know what the problem was, can you confirm that Emacs 23 did

Emacs 23 concealed the problem: it would let you continue invoking
subprocesses, but with every Locate subprocesses launched by Helm,
Emacs would leak 2 handles.  After some time (longer than the 2-3
hours you got with 24.2.9x), too many handles would have been lost,
and Emacs would become unusable.  Moreover, since the OS cannot reuse
a process ID of a process which still has some handle open on it, the
entire system would become unusable, because it could no longer launch
processes.

In v24.2.91, this handle leakage was plumbed, but doing so exhibited
another problem (which was already fixed on the trunk, btw), which
manifested itself in what you described.  Note that this problem only
rears its ugly head whenever an async subprocess is launched and then
killed without letting it exit in an orderly manner.  That is why no
one else reported the problem: I guess there are no more Helm users on
Windows who track the v24.3 pretests.

> - Is the current problem only happening on Windows (or due to my shell
>   setting)?

It is specific to Windows, but is not related to any shell settings.
It happens every time an async subprocess is killed by calling
delete-process on it.

> - Is it only with heavy process-creator users like me (by using Helm as my
>   almost only way to switch between buffers and files)?

See above: delete-process is the main trigger.  It prevents a slot
from being released in the array which Emacs on Windows uses to manage
subprocesses and network/serial connections.  When all the 32 slots
are used up in this way, Emacs can no longer launch subprocesses or
open network connections.

The code I added looks for these "lost" slots and releases them, so
that they can be reused.  On the trunk, the problem is avoided
altogether, but that requires deeper changes in the related code, and
I'd rather not make them at this late stage of the pretest.

> - Can you confirm the GDB command had to be "p *cp" and not "b *cp"?

Yes, of course.  Sorry.

Thanks for these interesting explanations.

No, I don't have any other platform to work from at the moment.

No. But the problem was (and may still be) initially very bound to my use of
Helm + Bash + Everything, all of that from Windows.

For information, I installed GnuTLS (for connection to our mail server on port
993) from the file `gnutls-3.1.6-w32.zip'.

Following your advice, I'm first trying with both in the same process (the
right setup, how I work daily I mean). Would it crash, I'd take the route with
2 "sub"-processes.

It's weird, these messages.  I cannot figure out what causes them.  I
see in your screencast that helm launches subprocesses like crazy (it
looks like every pattern character you type runs another Locate
process).  But even if I try simulating such a subprocess pressure, by
launching another 'locate' command every 100 msec, I cannot reproduce
the above messages on my system.  So some other factor is at work
here.

I need more data.  Please modify the way you set breakpoint at
w32.c:6410 as follows:

 (gdb) break w32.c:6410
 (gdb) commands
  > bt 4
  > p fd
  > p fd_info[fd]
  > b *cp
  > continue
  > end

In addition, please add a 3rd breakpoint, like this:

 (gdb) break w32proc.c:2276
 (gdb) commands
  > bt 5
  > p cp
  > p cp->wnd
  > continue
  > end

Please do this right at the beginning of a fresh session, and please
post the entire GDB session until it gets to the "unusable" state.
(You may need to enlarge the Screen Buffer Size property of the cmd
window in which you run GDB, for it to be able to keep all those
message and backtraces.)  It is very important for me to see all the
messages and backtraces one after the other, to see how the problem
develops.

Also, do you per chance have w32-start-process-share-console
customized to a non-nil value?  If so, can you try with it being nil?

Not sure if this is important, but every time this breakpoint breaks,
the character read from the pipe is \026, i.e. Ctrl-V.  Does that ring
any bells?

Helm is starting updating (create the first process) after the
`requires-pattern' value of source, for locate it is 3, so when entering
the third char in pattern the process start, return the data through a
process-filter, then stop the process-filter (setq *filter t) and kill
the process. When you enter the 4th char, a new process is created,
killed and so on.
You can avoid this by hitting `C-!' when starting helm session, then you
can type the whole pattern quietly and hit `C-!' again when done to
launch process, in this case only one process will be started.
(You can also type `C-!' at anytime to interrupt process too long to
finish, type more input and restart process again with `C-!')

This was just for info in case that help for debugging.

The "kill process" part was an important clue, thanks.  Using that, I
was able to re-create a situation similar to what happens for
Sebastien.  I installed a few changes on the emacs-24 branch to
prevent these problems, so I hope the next pretest will behave better.

FWIW, the improved handling of subprocesses on the trunk avoids these
problems altogether, at least in the scenario I used to re-create
them.

(There's still some strange issue with gnutls calls, as reported by
Sebastien, which I'm still looking in.  Not sure if this is an
additional problem or just "how things should work".)

> This was just for info in case that help for debugging.

Thanks, it helped.

Btw, I'm surprised that helm starts an async subprocess, just to kill
it after its output was collected.  Isn't this exactly what
synchronous subprocesses are for?  What is the purpose of such a
strange design? (except if you wanted to help find bugs in Emacs when
async subprocesses are launched and killed at high frequency ;-)

It allow among other things to run several sources all together (async
sources and normal sources), a synchronous process would block results of
all other sources.

But yes, having the possibility to use a synchronous process for a
single source would be nice in some cases.
Maybe I will write this in next versions of helm.

Indeed this is another feature I didn't think about ;-)

Thanks for your work on this.

IIUC, I guess the reason is not to block the user during typing: the fact that
Helm's locate is still collecting results does not hinder to type an extra
character to refined the search.

That consideration doesn't apply in this case, AFAIU, for 2 reeasons:

  . 'locate' must be (and is) reasonably fast for this feature to be
    liked by users.  Otherwise, the results you see will lag behind
    input, i.e. they will lie to you.  In your screencasts one can
    clearly see that you type a character and wait for the result to
    appear before you type the next one, which is what I'd expect, so
    a synchronous subprocess that does its job quickly will fit this
    very well.

  . Typing at a very fast rate will prevent Emacs from reading output
    from 'locate', if it is run asynchronously, so you will see no
    results at all in this case.  Not really useful, IMO.

I'm glad to have done that screencast. That way, you can feel how my system
reacts, and see I'm not a fool...

  │ w32-start-process-share-console is a variable defined in `C source code'.

As my Emacs was already quite weak[1], when reading your email, I decided to
attach GDB (I had a rest, for a couple of hours, with all those breaks),
launch a screencast, and try to reproduce problems.

Here for the live demo: http://screencast.com/t/PTVc7yA4u.

Not at all. I mean: it's not upon pressing C-v that all my problems occur.
But, yes, I occasionally use C-v, mainly in collapsed Org files, as it works
better than the Page Down key.

Why line 2285, not 2276?  Oh, I see, it's my fault: I looked into a
wrong version of the file.  Please use w32proc.c:2247 instead (with
the same breakpoint commands).

Thanks for the data, I will look into it.  But I really do need to see
this from the beginning of the session.  In particular, in what you
posted, the breakpoint at w32.c:6410 didn't break even once.

I guess you meant "p *cp"?  That's why I've type anyway in the GDB session I
sent to you [1].

[1] In fact, I did first type "b", but had lots of errors about breakpoints...

Eli,

In that same Emacs (not communicating anymore well with Helm and the mail
server), I tried to go on with other tasks: export an Org document to LaTeX.

That fails with "Creating process pipe: no error":

No new message in the GDB window, though.

You mean with gdb, like I do when Emacs is hanging or crashing?

But I'm sure it will come back[1], and that will happen, can you tell me what I
should type in the GDB window?
