bug#27816: 26.0.50; X protocol error: BadPixmap (invalid Pixmap parameter) on protocol request 55

I am using Emacs server, with emacsclient, and since last Git compile, I
am getting this error, and frames are being dropped or not appearing,
from time to time, not each time. It makes work hard.

When was your last Git compile before that?

> X protocol error: BadPixmap (invalid Pixmap parameter) on protocol request 55

The file etc/DEBUG describes how to start Emacs in the X synchronous
mode under a debugger (look for "X protocol errors").  Please invoke
Emacs as explained there, and then show the backtrace when the
breakpoint you set on the function x_error_quitter breaks.  This will
tell us which code causes these errors, and hopefully provide enough
hints to identify the reason of this.

Thanks.

Thank you. As I must run Emacs as daemon, to run emacsclient, to
start debugging, when I run it as daemon with the
option (x-synchronize t) then I get this error:

error: X windows are not in use or not initialized

To ensure normal operation, you should investigate and remove the
cause of the error in your initialization file.  Start Emacs with
the ‘--debug-init’ option to view a complete error backtrace.
Starting Emacs daemon.
(New file)

Or should I evaluate it later simply?

Yes, please evaluate it after you have created the first C frame.

Hello,

When I get in gdb, when attaching to process:

ptrace: operation not permitted

do I then get requirements to debug?

Ugh, sorry about your trouble.  Does it work if you invoke GDB via
sudo?

I would really like to solve this problem, as it appears each few
times it does not work. 

I am starting Emacs under user "admin" who reads emails, and answering
on many, from mutt mail client.

Emacs is started as daemon from a supervision script:

/usr/bin/emacs --user admin --chdir /home/data1/protected

I am now going to test it through GDB, and will let you know, but I
think it should work without sudo.

I am starting Emacs through screen, without X windows. So I started as:

gdb screen

then I do:

breakpoint x_error_quitter

It asks me for future loaded libraries, I said y.

Then I "run" and get screen and bash.

Then I start emacs as 

emacs --user admin --chdir /home/data1/protected (that is my home dir)

And then I connect to emacs as emacsclient

and evaluate (x-synchronize t)

and then if I connect each 4th or 5th time, not clearly known why,
then I get that bug, and X frame of new emacsclient is not appearing.

But back in debugger I do not see much, emacs as server is still
running. When I quit emacs, and screen, only then I can see backtrace
and it shows me nothing special related to emacs, just three lines.

Maybe you can help me, as I am doing something wrong, but I can replicate the bug.

If I just start emacs in X Window, and not in screen, in console,
under bash, without X Window, I do not get that bug, I tried repeating
it but I did not get it.

If I start it in console through screen, I get the bug.

No, I think this is a mistake.  You should first start screen, then
start GDB from that like this:

  gdb emacs

Then when GDB shows its prompt, type

  (gdb) break x_error_quitter
  (gdb) run  --user admin --chdir /home/data1/protected

(The "(gdb)" part is the GDB prompt, you don't need to type it.)
And then continue as you usually would:

If you start Emacs as above, you should see GDB take control when the
problem happens.  Then type

  (gdb) thread apply all bt

and post here everything it displays.

When I start screen, it must be started in console, not under X, so when I do:

gdb emacs

and later 

run --user admin --chdir /home/data1/protected

I loose the GDB prompt.

I will try setting it before run

Hello Eli,

Thank you. I had to set first the breakpoint, as GDB prompt would not come back if I run emacs.

OK, here it is attached.

OK the GDB prompt appeared I guess on that
breakpoint, I hope you got the message.

Thanks.

Earlier, asked when was your previous build, where this problem didn't
show.  I don't think you answered that.  Can you please provide that
information?

[Jean Louis]

Do you know any way to find out history of when user did git pull? Than I could find it easily and I will try to find it out anyway. Maybe I could recompile few previous versions like taking half time period since I know it worked and then half of the half. I will find and let you know.

Yes, "git reflog".

Also, if you still have the previous build's binary, you could start
it and then type

  M-x emacs-version RET
  M-: emacs-repository-version RET

The latter will show the Git SHA1 signature of the last commit on
master at the time you synced with upstream master.

I have done

git checkout 7dd72d7

and then re-compiled, and I see the bug is still
appearing, frame is sometimes cancelled or broken,
does not appear.

I was searching on Internet and found this:
https://lists.gnu.org/archive/html/bug-gnu-emacs/2007-08/msg00066.html

and then I am thinking, I have changed my default
font, and increased it. Maybe it is related to a
font.

As in that version 7dd72d7 I had other font
settings.

Now I just use default font, enlarged. I will try
to reset the font back, to see how it works.

Just to confirm that even above version has that bug. It was stable
before.

I have tried running emacs without ~/.emacs so it is not about my
fonts, faces, or settings, each few times frame is still not
appearing with BadPixmap error and request 55.

I will try tomorrow to go back to these versions below.

It could be that you have updated something else on your system, not
just Emacs's sources, and that indirectly caused the problem even in
builds that previously worked well.  If that is the case, it might
mean the problem which causes this is not due to some recent change in
Emacs, it was always there.

With that in mind, can you describe the sequence of actions that you
are using, after which these errors usually appear?  Also, are these
errors 100% reproducible, if you replay the same actions , or do they
appear only sometimes?

I did not update anything but ImageMagick, which anyway is not
compiled in Emacs, as it is version 7.

My system is not a distribution, and there are no automatic updates,
all tracking is in my head.

Yes, I can describe it.

Emacs is run as daemon by S6 supervision suite, through screen, as
below, nothing changed there since many months, this 2017 year.

I am connecting to emacs by the emacsclient, and the script below. I
had full stability until last 2 attempts to compile it with
ImageMagick, when I pulled last versions.

I am just about to try the one version before.

In last 2 previous versions it appears each 4th or 5th time, not
equally repetitive.

I am not sure if I am using correctly git checkout to try earlier
version. Today I tried it for third time, back in time, and this
emacs-repository-version d715e6d8c6a7f3507f4faca0961ac87d58fbfab8 is
still having the same problem.

What I do, I read email by using mutt, then I hit r to reply email,
including your emails, and I can see the notice from emacsclient on
console, but the graphic frame is dropped, and later I see the bug in
Emacs. Was not there before we started conversation and in the version
I used last.

I can just say that in this version
d715e6d8c6a7f3507f4faca0961ac87d58fbfab8, the bug appeared one time
only out of 30-40 times.

bug#27816: 26.0.50; X protocol error: BadPixmap (invalid Pixmap parameter) on protocol request 55

[Jean Louis]

Hello Eli,

My configuration of GNU Emacs is following:

./configure --prefix=/package/text/emacs-26.0.50 --with-sound=alsa --with-modules --with-x-toolkit=lucid --without-gconf --without-gsettings --without-libsystemd --without-dbus --without-pop --with-mailutils --without-imagemagick --with-x

I am still getting:

X protocol error: BadPixmap (invalid Pixmap parameter) on protocol request 55

And I have tried starting Emacs daemon in background without my
~/.emacs so it is still happening without custom configuration.

I have also tested it on different Window Managers.

emacsclient is basically remaining in memory as process, but the frame
is disappearing.

It is annoying as it makes programs wait on emacs client to come back,
as it blocks the console, right? Because it blocks the console, the
frame disappeared, the emacs client runs in memory but is not coming
back. Then I have to kill $(pgrep emacsclient) to make it work again. 

Do you think that reason for that can be that I use lucid kit?

The reason that I use the lucid kit is because there was similar bug
that Emacs daemon was crushing in the GTK kit. Lucid kit is much more
stable for me.

Now I cannot understand what happened that it started showing this
error, it is being shown in each 4th 5th or so attempt to spawn
emacsclient.

Please describe the sequence of actions leading to the problem in more
detail.  Here's what you said about that last time:

> What I do, I read email by using mutt, then I hit r to reply email,
> including your emails, and I can see the notice from emacsclient on
> console, but the graphic frame is dropped, and later I see the bug in
> Emacs.

This is not detailed enough for me to understand what is going on.  I
presume that mutt somehow invokes emacsclient and you then expect
Emacs to allow you to edit the response to an email message before
sending it.  But even if that guess is correct, it doesn't say whether
emacsclient is invoked to open a new frame or reuse an old frame,
whether that frame is a GUI frame or a text-mode frame, and whether
any other Emacs frames existed before the invocation of emacsclient
and were supposed to remain after you finish editing the response.

Btw, does this happen only when emacsclient is invoked from mutt, or
also with other programs?  What if you invoke emacsclient from the
shell prompt -- does the problem happen if you invoke it several times
in a row?

Also, are you sure the version of emacsclient that is invoked belongs
to the version of Emacs which is run in the daemon mode?

And finally, if you start Emacs not in daemon mode and then use mutt
as you normally do with daemon, does the problem persist or does it go
away?

> emacsclient is basically remaining in memory as process, but the frame
> is disappearing.

So Emacs now runs without any frames displayed?

> It is annoying as it makes programs wait on emacs client to come back,
> as it blocks the console, right?

That depends how emacsclient is invoked.  But if you invoke it from
mutt to edit a response, then you must let it block mutt, because mutt
cannot proceed with sending your response until Emacs is done editing
it.

> Do you think that reason for that can be that I use lucid kit?

I very much doubt that.

Something has changed on your system, it seems.

[Jean Louis]

Dear Eli,

Thank you so far. See below my answers.

I will try changing the lucid to gtk kit to see if
it is happening again.

That is just one application on how I start
emacsclient, but mutt is not related to it.

Another way of starting emacs is from terminal is
as this:

emacsclient -s tmp/emacs1001/server -c
Waiting for Emacs...

then each few times it works, like 85%, then it
fails.

Emacs is running in background under screen, and
it has (server-start) in .emacs or when I was
testing without ~/.emacs I evaluated
(server-start) in *scratch* buffer.

28078 pts/0    Ssl+   2:02 /usr/bin/emacs --user admin --chdir /home/data1/protected

Then I run the emacsclient in following fashion:

30859 pts/2    S+     0:00 emacsclient -c -s /home/data1/protected/tmp/emacs1001/server /home/data1/protected/tmp/mutt-protected-1001-30834-15325602171702686152

That means my main Emacs is running in console
under screen, it is not just backgrounded
daemon. But I do not think that it is related to
screen.

I have noticed it now, that if one frame is open,
the error is not appearing on the second frame.

It appears only when there is no existing frame,
and new frame instance has to be open.

> guess is correct, it doesn't say whether

The bug is appearing on opening a new instance of
emacsclient frame when there is no other frame
present.

There is no problem with text mode frames. Just
with GUI frame.

The text emacs is running under screen.

It happens if I invoke emacsclient by any means,
when it is opening first frame.

> What if you invoke emacsclient from the shell

Exactly like that, it happens if I invoke it from
terminal.

Also if I invoke it directly on keypress from
Window Manager or through mutt.

> Also, are you sure the version of emacsclient

Yes, very sure. I am running
emacs-repository-version
"cf1da46761675f1886e54765fa213c7bd7d93437"

And emacs is then in /package/text/emacs/ and
emacs client is then linked to the version I am
running:
admin-> ls -l /usr/bin/emacsclient 
lrwxrwxrwx 1 root root 40 Aug  2 18:55 /usr/bin/emacsclient -> ../../package/text/emacs/bin/emacsclient

and because it is in /package/text/emacs/ it
belongs to same version.

You mean if I run emacs without daemon? There is no problem at all.
But due to loading times, and configuration, it is not usable.

Emacs runs all the time, as main program under screen, I can access it
through screen. 

The problem is also happening when I do not run it under screen, I can
run it as user.

If there is no GUI frame, and I wish to invoke it by emacsclient, each
few times, the instance failes, GUI frame disappears, but the
emacsclient still runs in memory, until I kill it.

I do not have dsitribution and did not update system in any manner,
neither touched X Window or similar. I have updated security
certificates, just nothing special on the system.

I have re-compiled Emacs with just plain
./configure, and I am not experiencing that bug.

I will try it again just with lucid flag, to see
later does it happen again.

I have now discovered that if I compile it with
Lucid, that bug appears:

./configure --prefix=/package/text/emacs-26.0.50 --with-x-toolkit=lucid

and if not, there is no bug, with GTK.

I like Lucid kit more than GTK, but now I am
forced to use GTK for stability.

I have now recompiled Emacs with Lucid toolkit.

What I remember is that I used it for months
without the scrollbar, to spare the space on
screen.

Recently, I started using it with the default
option, so scrollbar is on the left in Lucid kit
(I guess so).

I have tested it now on:
emacs-repository-version
"cf1da46761675f1886e54765fa213c7bd7d93437"

with Lucid tool kit.

I found out, if I turn off the scroll bar, the
emacsclient invoked frames appear without
problems.

If I turn on scroll bar, on left or right side, I
get that bug message.

Martin, could you please look into this?  It sounds like there's some
timing issue with drawing the scroll bars in this scenario, perhaps we
attempt to draw the scroll bar too early or something?

I wonder why no one else is seeing this problem, though.  This part:

> The problem is also happening when I do not run it under screen, I can
> run it as user.

seems to indicate that just doing the following should reproduce the
problem with ~25% probability, in an Emacs built with the Lucid
toolkit:

  $ emacs -Q -nw
  $ emacsclient -s tmp/emacs1001/server -c

Jean, does the above indeed reproduce the problem?

Btw, Jean, do you have any Emacs-related settings in your X resources?
(Although -Q should bypass those as well, AFAIR...)

1) first in terminal: $ emacs -Q -nw

2) I evaluate (server-start) in *scratch*

3) In other terminal I write:   $ emacsclient -s tmp/emacs1001/server -c

7) On 7th attempt the frame did not appear, and terminal remained
blocked waiting for emacsclient to comeback

bug#27816: 26.0.50; X protocol error: BadPixmap (invalid Pixmap parameter) on protocol request 55

[martin rudalics]

[-- Attachment #1: Type: text/plain, Size: 2283 bytes --]

I can give the following additional information on this:


With a Lucid build from 23.8.2014 I get an incompletely drawn frame
(screenshot attached).  Clearly, drawing the scroll bar has not finished
yet.  A screenshot of a complete frame is attached for comparison.  In
the terminal Emacs the message

get-device-terminal: Display :0.0 does not exist

is displayed.


With a build from 9.11.2014 I get the same behavior but with the
meanwhile well-known message:

X protocol error: BadPixmap (invalid Pixmap parameter) on protocol request 55

In addition, the Emacs process consumes all CPU power it can get.


With current master the client frame is shown for a short moment and
then disappears.  The Emacs process does not stall.


In all cases, the problem occurs reliably - on the average about every
fifth call of emacsclient.  Lucid without toolkit scrollbars doesn't
build here any more, so far no idea why [does anyone grok ...

... I haven't built this for years?].  A motif build of master doesn't
exhibit this behavior but gets the Emacs process aborted here around
every seventh invocation of the client.  A gtk build exhibits no
problems AFAICT and a build without X toolkit support works well too.

BTW, I never use emacsclient and have no idea how to use it.  Is there a
way to stop the server from the starting emacs?

Could any of this be related to the change whereby we no longer wait
for the frame to become visible?

If you run Emacs in X synchronized mode and put a breakpoint on
x_error_quitter, can you see why the problem happens?  Which picmap
parameter is invalid?

Sounds like some Gnulib-related issue.  Perhaps Paul could help figure
this out.

I don't understand the question.  When Emacs starts, the server is not
started automatically, so I'm unsure what is it that you want to do.
Please tell me what I missed.

FWIW, works fine here. If it still happens in a clean build, I suggest
opening a separate report with system information, and attached
compressed config and build logs.

You mean that Emacs now doesn't consume CPU cycles any more?  In any
case, I think that the problem has existed ever since.  It just
manifests itself in different ways.  And it would be nice if someone
else who builds Lucid tried the scenario.  It's even simpler than Jean
Louis describes it:

(1) In one terminal do emacs -Q -nw

(2) M-x server-start

(3) In another terminal do emacsclient -c

(4) In the GUI frame do C-x 5 0 and repeat (3) and (4) at least five
     times.

I'll try to do that as soon as I understand how it works and how to
debug it.  Also IIRC synchronized mode didn't always work 100% reliably
here.  From the pngs it seems obvious that the arrows above and below
the slider didn't get drawn.

I suppose some leftovers in the build directory.  I have to build from
scratch.

The doc-string of ‘server-start’ says that this would "Allow this Emacs
process to be a server for client processes".  How can I "Stop this
Emacs process to be a server for client processes"?  Frankly I have no
idea what emacsclient is, how it works and how it interacts with the
server.

See server.el and the emacsclient sources, I think they are pretty
self explanatory, at least as far as the concept goes.

No idea how to run a TTY Emacs in X synchronized mode.  Anyway the

In the light of the present bug: Do you see any conceptual problems

There shouldn't be any, not in principle.  It's possible that some
initialization is missing somewhere, but we need to identify that
first.

I have no idea how to do that.  Passing no arguments to XtCreateWidget
doesn't help so IIUC the problem is somewhere in between
Xaw3dComputeTopShadowRGB and XQueryColor but maybe someone has a better
explanation.


BTW, this behavior has been reported in bug#5802 where it says:

   When the lucid version, emacs does not crash, but for some reason,
   when I run the emacsclient frame-creating loop that I described
   previously, sometimes the client frame disappears as soon as it
   appears, and I assumed that a crash had occurred. But in this case,
   emacs does not crash, and I only get the problem in a loop like this.
   Simply running "emacsclient -c" manually over and over at the
   command-line never causes a frame to disappear. So, I think I will
   move forward using the lucid version, and you can mark this as a GTK
   problem.

And obviously this is bug#23499 where you stated:

   Error code 4 is BadPixmap, according to my references.  I hope some X
   expert will chime in and tell why this happens.  (I actually don't
   understand why we try to create the scroll bar when the frame is
   iconified.)

Then I guess this should go in etc/PROBLEMS.

You can start emacs server in terminal, and then
open at least one GUI frame and do (x-synchronize
t), it works that way.

As far as I can tell from the code, this only affects the current
terminal (GUI frame).  What seems to work is this:

    emacs -Q -nw --eval '(setq x-command-line-resources "emacs.synchronous: true")'

I've tried the recipe --without-toolkit-scroll-bars; the error does not
occur under this configuration.  There is some other minor trouble (not
really related to this bug I think): the scrollbar does not get drawn
(the space where it should be is all white instead) when first opening
the frame, unless I've set synchronous mode as above.

Thanks, yes.  I earlier got around this by starting the client once and
simply x-synchronizing from there.

I wouldn't be too sure about this one.

I've seen that too.  I'm afraid the non-toolkit code has aged much over
the past years.  Nobody works on it.

Lisp Backtrace:
"redisplay_internal (C function)" (0x0)

But with ‘x-synchronize’ I reliably get the Xaw3dComputeTopShadowRGB
bug.

BTW could you try this with a motif build?  Here this gets me the backtrace

and the usual BadPixmap error.  So the bug behind all this is probably
neither scroll bar nor menu related after all.  I conjecture that
deleting the last GUI frame from a TTY started server messes up
something we do not initialize properly when invoking another GUI client
from it.  This conjecture is supported by the fact that when I leave a
client frame open and fire up a new terminal, I can invoke the client
from the new terminal as often as I want without any problems ...

That's the worst case scenario, yes.

And I confirmed my conjecture here by using the attached patch.  Please
try it.  I now start thinking that the GTK bug is not a GTK bug after
all ...

Evaluating (x-synchronize t) in the first X frame doesn't seem to have
any effect for me.  My interpretation of the backtraces is that the
presence of XSync() indicates synchronous mode, and since yours lacks
that you are not actually in synchronous mode (I am somewhat out of my
depth here though, so perhaps this is nonsense).

Attached are backtraces using lucid and motif.  The -x-commandline-synch
ones are where I used --eval '(setq x-command-line-resources
"emacs.synchronous: true")', the -x-synchronize-call are where I
evaluated (x-synchronize t) after creating the first X frame (and they
end up the same as the one where I did nothing, as I mentioned above).

With this patch I can't produce the badpixmap error here.

Looks reasonable, thanks.  If this solves the problem, please push.

This should have been fixed now.  Please have a look.

Thanks, martin

I can confirm it's fixed.

I have pulled right now, compiled, and bug is
again there.

My configuration

./configure --prefix /package/text/emacs-26.0.50 --with-mailutils --without-imagemagick --without-pop --with-x-toolkit=lucid

The bug is _still_ there.  The patch has not been applied yet because I
expected you to test it first.

Thank you for the reminder. I tested it 20 times,
and it seem to work.

Thank you, let me know when it is applied.

Thanks for the information.

I pushed a fix that spares non-toolkit builds.  Please try again.

Pushed.  It seems that increasing the heap size might slightly diminish
the frequency of these crashes but I didn't find anything conclusive.

You're probably right here.  But note that the OP of Bug#23499 did do that
under GDB as

run -Q -nw -xrm "emacs.synchronous: true" -f server-start

and did not get any XSync()s either.  In either case some advice on how
to debug the client under X would useful.  I'm still completely ignorant
in this department.

From what I could tell, the '-xrm' option is ignored when '-nw' is
used, which is why I used '--eval' instead.

Sounds elementary.  I nevertheless added your proposal to etc/DEBUG.

I guess we may as well close the bug then.
