Since some time, I have very strange problems in Gnus' message-mode.
That is, I want to follow up to some message and press `F' so that I get
a new message-mode buffer with the quoted text of the original message.
Then I want to kill the text which I don't comment on.  I do that by
simply setting point above the text to be killed and press and hold C-k.

When I do so, I frequently get errors like the one below.  I have
totally no clue at all what that should mean to me.  I grepped all elisp
files I have here (emacs itself + all packages I use) for
`funcall-interactively' but the only occurrence is in
`repeat-complex-command' which I did not call.  I just did `kill-line'
repeatedly.  I could reproduce the exact error a few times when trying
to follow up to different messages.  Now, that doesn't happen anymore
though it's still the same emacs instance.

The vectors below denote auto-generated AUCTeX functions (see
`LaTeX-math-initialize') but don't see how those end up in dbus
events...  I don't think that has something to do with AUCTeX
specifically.  I had similar issues previously where during repeated
killing in a message-mode buffer point would just jump to some different
location which see below.

It really seems that during repeated killing in message-mode, strange
things happen.  Now I performed another test: in a message-mode buffer I
typed START, <return>, and then pressed and held C-k until it beeped,
and then did M-x view-lossage.  That's the output:

--8<---------------cut here---------------start------------->8---
 S [self-insert-command]
 T [self-insert-command]
 A [self-insert-command]
 R [self-insert-command]
 T [self-insert-command]
 <return> [newline]
 C-k [kill-line]
 ...
 C-k [kill-line]
 <up> [previous-line]
 <up> [previous-line]
 <up> [previous-line]
 C-k [kill-line]
 ...
 C-k [kill-line]
 M-x [counsel-M-x]
 <return> [ivy-done]
--8<---------------cut here---------------end--------------->8---

I did NOT press <up> between all those C-k!  I just pressed and held
C-k.

I tried once again in another message-mode buffer, and this time out of
sudden point jumped below the text I wanted to kill.  `view-lossage'
claimed that I've pressed <down> and C-/ (which is `undo-tree-undo'
here) several times. No, I did NOT!

I've tried repeated killing in elisp, org-mode, and a fundamental-mode
buffer but couldn't reproduce the issue there.

Any idea how to debug that?

This problem has nothing to to with dbus in particular.  Today I had a
different occurrence of the bug where during repeated killing in a
message-mode buffer I suddenly got an error about something with a
file-notify event.  I've stopped killing then just to read the error
message, and then I restarted killing which out of sudden made emacs
crash.

Since then I've let emacs run in the debugger.  Just right now I had
another crash during repeated killing in message-mode, and below is the
backtrace.

To me that backtrace looks like there's a bug in the error printing code
which seems to cause the crashes.  But it does not explain the source of
the errors I sometimes get during pressing and holding C-k in
message-mode.  Those errors always sound as if events of the wrong kind
have been delegated to some event handlers, e.g., `dbus-handle-event'
might have received some file-notify event or `file-notify-handle-event'
might have received some keyboard event.

Any ideas how to debug that?  The problem is that it is not really
reproducible, it just happens once every second day or so.

Just now, I had three other strange errors during killing in
message-mode.  The first two were about errors in
`file-notify-handle-event' which was called with something wrong.  With
the first error, it received a buffer (!) instead of an event, with the
second error I think it received something else which I can't remember.
At least it hasn't been a file-notification event.

Well, and then the third error crashed emacs.  That's the reason why I
can't check the first two error messages anymore.

Here's the backtrace:

I think this is the same problem as the one fixed in bug #21337,
except that the cause for the problem is different: where it was
GnuTLS in that bug, it's something else in yours.

So I suggest to read the description of the root cause posted by
Robert Pluim in http://debbugs.gnu.org/cgi/bugreport.cgi?bug=21337#31,
and then look for something very similar, but involving other sources
of input events, perhaps D-Bus.  The symptoms you describe exactly
match what he explained there.

Yes, seems so.

The problem is that I have almost no idea what that code does and how it
is intended to work, so I can't really debug it in a sensible way.

And to make things worse, I think this issue also has some timing
component in it.  That is, it only happens when I press and hold C-k for
at least one or two seconds which kills quite a lot of lines given that
I use a very fast keyboard repeat rate.  When I kill just the lines of a
paragraph like this one, then take a short pause, then kill the next
one, the issue is much less likely to appear.  So emacs needs to be
flooded with events in some sense.

If you have some ideas where things could go wrong, I'm happy to do
whatever may help.  Maybe adding some debugging code or conditional
breakpoints could narrow down the scope a bit?

BTW, the last errors came from `file-notify-handle-event' but I'm
reasonably sure that in this emacs session I only had used Gnus so far.
I don't use auto-revert-mode, so actually filenotify.el should not even
have been loaded so far and no watches should have existed.  My current
emacs session is the same: only Gnus => (featurep 'filenotify) ;=> nil.
Does that give any clue?

Bye,
Tassilo

You mean, wait_reading_process_output?  Please feel free to ask
questions about the things you don't understand.

In a nutshell, it waits until one of the input sources has some input,

I think things go wrong exactly like in that other bug: we have some
source ready to be read from, but dispatch those events to a "handler"
for another source.

I'd start by looking at the indicators returned by 'pselect'.

My theory is that we think there's an inotify event waiting to be
read, where in fact the event is of another kind, perhaps from D-Bus.
The flags returned by 'pselect' should tell you.

As far as I understand, the file descriptors with pending input are
collected in the fd_set Available, and then this loop gives, e.g., dbus
and inotify handlers a chance to read input from the file descriptors
and convert it to events.

      for (channel = 0; channel <= max_input_desc; ++channel)
        {
          struct fd_callback_data *d = &fd_callback_info[channel];
          if (d->func
              && ((d->condition & FOR_READ
                   && FD_ISSET (channel, &Available))
                  || (d->condition & FOR_WRITE
                      && FD_ISSET (channel, &write_mask))))
            d->func (channel, d->data);
        }

I wondered why channel is not removed from Available here.  I mean,
input was available, and then the handlers registered using add_read_fd
by inotify or dbus consumed the input, so there's probably no input
left.  So I tried this patch

If no one objects in a week, please push this, and let's see what it
breaks.

Thanks.

Yes, I'll do.  And I'v Cc-ed Jan in this mail because he's the original
author of that code and probably knows best if that's the right thing to
do.

I've run with this patch for about a week now and the issue hasn't
occurred anymore.  So I just pushed it and close the bug report with
this mail.

Thanks for your assistance!

What if it was the 'FOR_WRITE' part of the condition that triggered?
Perhaps we should split the 'if'.

I think in this case, channel cannot be in Available so by handling this
case we could only save one needless operation.  But that might be
reason enough, so I committed the following patch.

Hi guys,

apparently my commits

  bfa1aa8 * Improve last commit to process.c
  27f8719 * Remove callback-handled channels from Available set

didn't really fix this problem.  I still occasionally get those strange
errors, e.g.,

Debugger entered--Lisp error: (wrong-type-argument number-or-marker-p CHARACTER_POSITION)
  dbus-handle-event((dbus-event FILE_NAME CHARACTER_POSITION LINE_NUMBER COLUMN_NUMBER OWNER_OS HOST_NAME USER CLASS NAME ATOM INTEGER SAVE_TARGETS))
  funcall-interactively(dbus-handle-event (dbus-event FILE_NAME CHARACTER_POSITION LINE_NUMBER COLUMN_NUMBER OWNER_OS HOST_NAME USER CLASS NAME ATOM INTEGER SAVE_TARGETS))
  call-interactively(dbus-handle-event nil [(dbus-event FILE_NAME CHARACTER_POSITION LINE_NUMBER COLUMN_NUMBER OWNER_OS HOST_NAME USER CLASS NAME ATOM INTEGER SAVE_TARGETS)])
  command-execute(dbus-handle-event nil [(dbus-event FILE_NAME CHARACTER_POSITION LINE_NUMBER COLUMN_NUMBER OWNER_OS HOST_NAME USER CLASS NAME ATOM INTEGER SAVE_TARGETS)] t)

just now when killing text in a message-mode buffer.  And I also had
some crashes again.

Should I revert these two commits?

Bye,
Tassilo

I understand those commits made the situation better, perhaps even
much better.  If that's correct, I see no reason to revert them, just
to continue investigating the problem.

One idea for investigation would be to write special code that would
collect data about these events, from the moment they are detected by
pselect until they wind up in the D-bus handler, and put that data
into a data structure accessible from Lisp.  Then you could examine
that data when the problem happens, and analyze it.

Thanks.

Next strangeness: in this very mail I wanted to kill all lines until the
one below but apparently the line above was skipped.  View lossage says
 ...
 C-k [kill-line]
 <down> [next-line]
 C-k [kill-line]
 ...
but I've never pressed <down>.

And another thing which occurs to me recently (which might be completely
unrelated) is that I visit a file, and the effect of any key I type
becomes visible only after the next key has been pressed.

I had that feeling initially but it might be completely subjective and
wrong.  Maybe I just didn't write email too often on these better days,
I don't know.  But the last few days were horrible again.

Yes, of course.

Well, yes, but I have no idea how to do that.

As far as I understand, that loop that I've patched is the thing which
calls callbacks which read input from file descriptors in order to
create Dbus or file-notify events.  Looking at the last error

Debugger entered--Lisp error: (wrong-type-argument number-or-marker-p CHARACTER_POSITION)
  dbus-handle-event((dbus-event FILE_NAME CHARACTER_POSITION LINE_NUMBER COLUMN_NUMBER OWNER_OS HOST_NAME USER CLASS NAME ATOM INTEGER SAVE_TARGETS))
  funcall-interactively(dbus-handle-event (dbus-event FILE_NAME CHARACTER_POSITION LINE_NUMBER COLUMN_NUMBER OWNER_OS HOST_NAME USER CLASS NAME ATOM INTEGER SAVE_TARGETS))

  command-execute(dbus-handle-event nil [(dbus-event FILE_NAME CHARACTER_POSITION LINE_NUMBER COLUMN_NUMBER OWNER_OS HOST_NAME USER CLASS NAME ATOM INTEGER SAVE_TARGETS)] t)

the thing passed to `dbus-handle-event' looks like a dbus event except
that its contents are bogus.  These events are created by
xd_read_message_1 in dbusbind.c, however that function is reasonable
strict and could not create the bogus event above, e.g., it calls
make_number on the event type which becomes the second item in a
dbus-event, i.e., the CHARACTER_POSITION above which is no number.

So what should that tell us?  I don't really know.

If you feel that the changes didn't improve the situation, then
reverting them is indeed TRT, IMO.  At the very least, the code will
be simpler after the revert.

What are your difficulties?

Basically, the idea is to record the last N events in some Lisp data
structure.  I would start with raw events as they are read from the
various sources, and move higher up the "food chain" as you gather
more insight into the problem.

Yes.

Either that the event was not a valid D-Bus event, or that it weasn't
created by that function?

Btw, dbusbind.c seems to have its own debugging facilities, so another
idea would be to turn them on.

From the backtrace I have the feeling that it was created as another
event, and the marker `dbus-event' has been pushed there later. But I
cannot prove this.

Yes. Compiling dbusbind.c with the setting MYCPPFLAGS=-DDBUS_DEBUG
enables traces to emacs' STDOUT. Don't hesitate to ask if you need more
information for interpretation of them.

You can also add more traces in dbusbind.c using the macro XD_DEBUG_MESSAGE.

Well ... starting next Monday, I'm offline for about a week.

Best regards, Michael.

I have the same feeling as Michael.  xd_read_message_1 and
inotify_callback / inotifyevent_to_event are the only functions creating
dbus and file-notify events here, and they'd all barf if the data they
read was screwed.

And keep in mind that it's not only about these kinds events.  Sometimes
keyboard events also get screwed, e.g., in the case where view-lossage
tells me that I've typed a key which I actually didn't.  Or in the case
where I get a crash where probably the event is handled on the C-level
where a broken event causes a segfault instead of being gracefully put
in the debugger.

My problem is that the search space is not so small.  Assuming that
events are created correctly at first, I'd probably start recording
events at kbd_buffer_store_event but then I'd want to track when, where,
and how they are modified.  Well, just the first would be better than
nothing I guess.  I'll try that out.

If I had at least a reproducible recipe, I'd just try reverting the
changes to keyboard.c of the last months one by one and see if I can
find the culprit.  But right now (with my invalid reverted in process.c
fixes) I'm unable to provoke such an error although I've tried very
hard.

I'm using that now but as said, I don't think that's where the problem
is.

Can someone give me a hint what I'm doing wrong?  With the changes below
keyboard.c still compiles but the step

  ./temacs --batch --load loadup bootstrap

starts using up all my RAM and swap space until I kill it.

Fmake_vector needs a Lisp integer as its first argument, i.e. you need
to use make_number.  (And I'd suggest to use Qnil or some other Lisp
object as the second, not a C zero, although currently Qnil's value is
indeed zero.)

`unread-command-events' comes to mind. It is used to push events back
which have been read, but which shall be handled later. Maybe something
is broken in that mechanism.

Commit 5022e27dac4c13651941e425dbec5b3a2cecdae4 has made heavy changes
here. I do not say that it has broken things, but it was pushed about 2
weeks prior your bug report. Timing matters.

Maybe you can check whether the problem still happens with a checkout
dated before Aug 4th. I know, hard to reproduce ...

Ah, ok.  And then Vth_event_buffer_idx also needs to be a Lisp integer.

I guess that naive approach won't work because make_lispy_event is not
free of side-effects.  It actually modifies the event so calling it

Well, I now try following Michaels suggesting of reverting this one
commit about `unread-command-events'.

Indeed, the timing would be perfect.  I'll try that out.

I'm now running with a local branch where that commit has been reverted.
No error until now but of course that has nothing to say.  I'll just
keep using it for the next few weeks.

But looking at the changes of this commit, I think the functions it
touched are not used when editing in a message-mode buffer.  At least I
get no trace output from tracing all functions reported by

git show 5022e27dac4c13651941e425dbec5b3a2cecdae4 | grep @@ \
    | sed -e 's/@@.*@@ //' | sort | uniq

which obviously relies on the git diff hunk headers naming the right
functions but I think they do.

Bye,
Tassilo

You need to run this under GDB to see what's going on.

Indeed, you probably should construct the Lisp object from the event
by hand.  Especially since we suspect some events might be invalid.

That's okay, but only as a means of switching your attention to the
alternative source of those bogus events (like unread-command-events).
The commit mentioned by Michael is not going to go away, as it fixes a
bad problem.  However, it might need some adjustments to prevent
adverse side effects, if indeed reverting it will solve these
problems.

There's also 30a6b1f81412044aa7dda5573b0142a0a03c4fd3, although it was
supposed to deal only with recording input events for the purposes of
keyboard macros.

Uh, well, does "by hand" mean reimplement make_lispy_event?  I've tried
cheating and calling that on a copy of the actual input_event.  At least
that compiles, emacs starts, and after some time my th-event-buffer will
have the number 7 at index 0, and eventually it'll segfault.

But I'm probably barking up the wrong tree anyway.
kbd_buffer_store_event doesn't seem to be called very frequently;
certainly not for every event.

I've been running with the latest master with that single commit
reverted for the past 10 days and never had this issue again.  So I'm
tempted to say that this commit is most probably the culprit.

The only effect of that change is to call record_char on some events
that might have evaded that before.  record_char does 2 things:

 . it adds the event to recent-keys, a Lisp array
 . it records the event as part of a keyboard macro, if a macro is
   being recorded

(There's also the "dribble" part, but I doubt that you are running
with that enabled.)

So I wonder how could any of that cause the kind of trouble you
reported.

If you undo the revert of that commit, do you start seeing the problem
again?

If you do, please see which of the "unusual" events, if any, get
passed to record_char, and whether they are recorded as part of
recent-keys and keyboard macros (assuming that you are used to define
and invoke macros in your routine work).

Thanks.

Me, too.

I'm back on master now so we'll see.

I added some debug code which spits out something like

record_char: 107
  -> NOT storing as part of macro
  -2> set to recent_keys at index 28

where the 107 is the result of formatting the Lisp_Object with "%S", the
second line indicates if store_kbd_macro_char is doing something, and
the -2> line means that the second ASET (recent_keys, ...) invocation in
record_char has been executed.

That's what you had in mind, right?

Yes, but not too frequently.  Macros haven't been involved when I had
those issues unless it is possible that some macro recording/replaying
I've done much earlier could have had a side-effect which appears much
later when killing text in a message-mode buffer.

Ok, great.  But somehow my debugging code changes the behavior with
respect to hitting C-g in the minibuffer and I don't see how that can
happen.

Concretely, normally C-g in the minibuffer will exit the minibuffer or
exit the recursive minibuffer popping to the previous one.  But with my
change, I need to hit C-g twice in quick succession.  A single C-g does
nothing (record_char isn't called at all), and pressing it many times
with reasonably long pauses in between does nothing, too (no
record_char).

Oh, wait.  Now I can tell you exactly how quickly I have to type the
second C-g.  When I type C-g, the echo area shows Quit and then switches
back to the prompt I had before.  The second C-g must come within the
time the echo area still shows Quit.

That's the output I get when doing M-x C-g C-g quickly.  The second
record_char output appears just after the second C-g in the sequence.

--8<---------------cut here---------------start------------->8---
record_char: 134217848 ;; M-x

record_char: 7 ;; issued after C-g twice in quick succession
  -> NOT storing as part of macro
  -2> set to recent_keys at index 17
--8<---------------cut here---------------end--------------->8---

And these are my changes.  Do you see anything stupid in there, or is
this some sort of a timing issue (which would at least partially explain
why I seem to be the only one seeing these "strange problems")?

Do you see something in *Messages* that isn't there without your
changes?  You call Fformat, which conses a string, which can cause GC
or call some Lisp (depending on your customizations).  If that causes
some echo-area message, it could maybe cause something like this.

Does this happen in "emacs -Q"?

Or it could be that some code that runs as result of this throws to
higher level and resets the quit flag.

Ah, sorry, I forgot to tell you that this behavior is there also with
"emacs -Q" so we can rule out customizations.

Also, if there's some more direct way to print a readable representation
of a Lisp_Object from C, I can try with that.

But how could a GC (or maybe just some small slowdown induced by
printing) reset the quit flag?

It can't, and that's not what I meant.

I think I found the problem: the call to Fformat eventually calls
print_object, which calls QUIT, which resets quit-flag.

So you need to change the beginning of read_char like this:

  ptrdiff_t count = SPECPDL_INDEX ();
  specbind (Qinhibit_quit, Qt);
  AUTO_STRING (format, "%S");
  printf ("record_char: %s\n", SSDATA (CALLN (Fformat, format, c)));
  unbind_to (count, Qnil);

I've seen it now.  Well, that's not what I would have expected.

Yes, that works.  So that's the C version of (let ((inhibit-quit t))
...).  So specbind creates a dynamic binding, and with unbind_to you pop
entries up to a given index again, right?

You should expect any potentially prolonged operation to call QUIT
somewhere in its loop.  That's standard Emacs coding practice, meant
to make Emacs more responsive.

Yes.  See Flet (modulo the clutter) for a definitive evidence.

(Btw, unwind-protect is implemented using the same mechanism in C.)

Ok, so QUIT; in C code basically means, here is a position where the
current lisp execution could be aborted.  If it weren't in
print_object(), then you couldn't for example abort printing a list with
gazillions of elements and emacs would get stuck while doing so.

Looking at QUIT, the difference between my original code and the new one
is just when process_quit_flag() is called.  process_quit_flag() always
signals quit.  So with the new code, the signal is handled by the right
recipient.  Who consumed (and discarded) it before?

Well, I think I just remember that I want to bind Qinhibit_quit to Qt
whenever I need to call Lisp functions from C.

Correct.

process_quit_flag itself:

  void
  process_quit_flag (void)
  {
    Lisp_Object flag = Vquit_flag;
    Vquit_flag = Qnil; <<<<<<<<<<<<<<<<<<<<<<<

The gotcha here is that C-g is handled specially, i.e. not by
process_quit_flag, during processing of user input.  That special
handling was bypassed because process_quit_flag attempted to process
it too early, and reseted the flag afterwards, thus disabling that
special processing.

In debugging code that isn't supposed to disrupt the control flow,
yes, that's a good rule.  But if you write C code for "normal"
processing, then no, don't inhibit quitting like that just because you
call Lisp.

Ok, I see.

What's a bit confusing is that it has been handled at least partially:
Quit was echoed but there was no "real" effect.  So I guess somewhere
the quit signal emitted by process_quit_flag() was caught by whatever
code does echo messages and then re-signalled, and the top-level handler
discarded it because Vquit_flag was nil.

The question is if Quit should have been echoed at all?  Well, it's good
for the user to see that emacs received it but then he'll wonder like me
why it has no effect.  So maybe it should have echoed "Quit [ignored]"
or something like that.

That's what process_quit_flag does.

These situations are not supposed to happen.  IOW, that was a bug.

Hi Eli,

I've run one week with master + my debugging code and then almost
another week with just master in order to rule out a Heisenbug that
vanishes when one tries to observe it.  The problem didn't happen again;
it seems to have magically disappeared.  So I'm closing this bug and in
the unlikely case that it'll pop up again, report a new one.

Thanks for all your assistance!

Bye,
Tassilo
