bug#17046: 24.3.50; On startup emacs frame has no minibuffer or windows decorations

[Robert Marshall]

On starting emacs with desktop enabled the frame appears normal until
loading is complete when the window title/ iconize button etc disappears
together with the minibuffer. I have a screenshot of the frame (if
needed for clarity)

Commenting out these lines in .emacs gets rid of the problem

(desktop-save-mode 1)
(add-to-list 'desktop-globals-to-save 'compile-command)
(add-to-list 'desktop-globals-to-save 'compile-history)

though there's rather a lot of buffers created when those lines are
present!

If I create another frame that appears normal.

initial-frame-alist ;; is set to
((menu-bar-lines . 1) (background-color . "mint cream") (width . 120) (foreground-color . "DarkOrchid1") (font . "Inconsolata-12") (alpha . 90))

default-frame-alist ;; is set to 
((menu-bar-lines . 1) (background-color . "mint cream") (foreground-color . "DarkOrchid1") (font . "Inconsolata-12") (width . 80) (alpha . 90))

I did a build from bzr which produced this problem my previous build
(Dec 23rd 2013) didn't have this issue

Can you please do M-: (window--dump-frame) in that frame and post the
contents of the buffer *window-frame-dump* here.

Thanks, martin

Thanks.  According to that dump you should see the minibuffer.  What
does evaluating

M-: (frame-parameter nil 'minibuffer)

give?  The fact that no title bar is visible is even more strange.  Do
you see menu bar and scroll bar normally?  Post your screenshot, it's
simpler than telling details.  And what happens when you maximize the
frame and restore its normal size immediately afterwards?

Definitely no minibuffer, I had to do the M-: commands very carefully
as I couldn't see what I was typing!

Unfortunately after Juanma's suggested change (and then reverting it
and an emacs restart) I get the frame *with* a minibuffer but without
the window decorations.

When that command gives me:

#<window 4 on  *Minibuf-0*>

but that is probably not relevant in the new situation

(sorry I wasn't sure if you needed to do something special to
associate an image with a bug report, I'm just attaching it to the
email) I'm attaching the screenshot together with a normal emacs frame
for comparison

I'm running with a fairly standard kde plasma desktop - so the bit
above the menu bar is all missing (and the left hand frame is the
faulty one)

Ah now that's interesting! When I maximize - selecting the relevant
frame in the toolbar and using that popup WM menu option (I've also
tried using M-<f10> and get the same result) the frame moves to the
top left of the screen but *doesn't* maximise it remains (AFAICT)
the same size and the minibuffer now disappears! With no minibuffer I
then get

#<window 4 on  *Minibuf-1*>

for the frame parameter. When I take off maximisation the minibuffer
is restored - but still no window decorations.  Is this a kde/plasma
bug - or maybe a gtk/plasma bug?

Sorry, I forgot.  You can always insert such text in *scratch* and
evaluate it there.

Very good.  It's still a complete mystery to me how the title line can
disappear.  Usually this happens only when the window manager thinks
(because Emacs told him) that the frame is fullscreen.

Sorry. How can a non-existent minibuffer disappear?

As a rule, the title bar should disappear if and only if Emacs asked for
the frame to become fullscreen where it doesn't matter if the frame
actually is fullscreen.  For example, here on Windows I can make a frame
fullscreen via F11, maximize and demaximize it via Windows commands and
get a normal-sized frame without title.  So far I've not been able to
produce a similar behavior on GTK.

Even when I maximize (with a unbuggy frame) I still see the title
line, is this windows vs kde? I can't see anything in kde system
settings which might affect this.

Sorry the context is after putting desktop-restore-frames to nil _on
startup_ the frame came up ok (as I said in the snipped bit of the
message you were replying to:

      Unfortunately after Juanma's suggested change (and then reverting it
      and an emacs restart) I get the frame *with* a minibuffer but without
      the window decorations.)

so it is there at startup but on 'maximize' (which isn't really
maximize) it disappears.

Having just tried it again (and the exit put desktop-saved-frameset
back). I'm again getting a single frame with no decorations and no
minibuffer I'll save that desktop file - it looks to me as if there's
only one frame now in the desktop file (at least there's only one
frameset--id which I assume is the determinant)

Anyway, I'm having trouble understanding how it happens. Could you
please make a step-by-step description, starting with a minimal .emacs

Me2! Do you want me also to start with an empty .emacs.desktop file?
It may take a little time to replicate from a clean sheet but I'll
give it a go.

With no desktop file, yes.

It's the best way to isolate what's relevant to the bug and what's not.

A frame with a 15 lines window above and a 14 lines window below.  Looks
normal to me.

Maximizing preserves the title.  Fullscreen (via F11) doesn't.

Once more (I'm confused): What I wanted you to try is to get that bad
frame (the one without title decoration and without minibuffer) back on
screen.  Let's call this the "bad base state".  Now please in that state
do:

(1) Apply your window manager's key shortcut to maximize it and then the
     shortcut to restore its normal size.  Do title bar or minibuffer
     come back?

(2) In the bad base state type F11.  Does anything change?  Type F11
     again.  Does anything change this time?

For me the only explanation for a missing title in a normal-sized frame
is fullscreen mode gone astray.  Does anyone have a better explanation?

Thanks, martin

Do you mean the "bad base state" frame was showing two windows before
maximization?  Or do you mean the frame whose state was saved and should
have been restored was showing two windows?  Or does the "second window"
refer to the minibuffer window?

You mean it simply does not maximize, as can be seen on the screenshot.
Are the three buttons (minimize, maximize, delete) on the right of the
toolbar something you've seen before on your system?  I don't see them
on the screenshot you sent earlier.  What happens when you click on
them?  Finally, there are no scroll bars and no right fringes on this
frame which probably count as more bugs.

The frame dump you sent earlier indicates that the Emacs frame/window
handling code considers everything in order.  This means that the bug
happens either in the communcation between window manager and Emacs or
that Emacs doesn't redraw the frame orderly.  But all this is dwarfed by
the fact that there's no title line and the strange buttons on the right
of the frame.

Remarkable.  One clue less for the disappearance of the title line.

I can only assure you that yours is the strangest behavior I've seen
over the past year.

 > buffers?

OK.  I'm happy that the problem is reliably repeatable.  So please
proceed as follows:

(1) In the frame whose state you save, just before exiting it, do
`window--dump-frame' and post the contents of the *window-frame-dump*
buffer here and also the value of `desktop-saved-frameset' for control.

(2) Repeat the experiment with two side-by-side windows (that is call
`split-window-right' before saving the desktop) and proceed as described
in (1).

Thanks, martin

Sorry for the confusion I've caused here - those 3 buttons belong to
another application whose window I have shaded (so that the rest of it
is not visible). The emacs scroll bars and fringe disappear when the
window gets the maximise command.

When the maximise happens - as you see the frame doesn't appear to
change size but it does relocate - it starts off in the centre of the
screen and f11 causes it to move to the top left of the screen - so
the correct place - if only the rest of the frame were the correct
size! It would appear that the frame is only showing part of what
should be there - on further experimentation I've managed to
'maximise' so that the top window appears ok but the lower window only
displays a few lines with no mode line visible and C-x o takes me into
that area of around 3.5 lines and I could scroll up and down in that
window without a mode line.

You mean before exiting emacs and that saving the desktop file and
with an un'maximised' bad frame? I get (evaluating it in *scratch*)

that option is at the end)

So just one buffer in the frame split into 2 side by side windows
(with the issues with two windows I'd been using split-window-below
and displaying another buffer in the second window).......

In attempting to restart to do this test I was unable to replicate the
error for some time, I started emacs 3-4 times without the problem,
eventually I got a bad frame and got the results below:

bug#17046: 24.3.50; On startup emacs frame has no minibuffer or windows decorations

Ahh... OK.

But they do so only on this "bad" frame, I suppose.  Maximizing a "good"
frame doesn't cause them to disappear.

You've done everything as I wanted, thanks.  This one reveals a strange
bug, namely in the last line of

 > #<window 4 on  *Minibuf-0*>   parent: nil

 > char left: 0   top: 35   size: 992 x 1   new: 240

instead of 992 the minibuffer window should have a character width of
124, like the other windows.  Unfortunately, this gives no clue at all
since we don't even record the minibuffer sizes in window states :-( I
suspect it's a problem the dump can't handle because at the time it
dumped the value the minibuffer was in an inconsistent state.

So all we have is a root window with 34 lines an upper window with 17
and a lower window with 18 lines and these get recorded correctly.

... which I didn't expect.  But again the values look correct and even
the minibuffer window has the correct char width now,

namely 124 as in 124 x 1.

And the frame dump reveals no problems.  I'm just as puzzled as before.

Juanma must likely help now for the HOWTO:

Can you reproduce the problem with an empty .emacs, just loading the
desktop file.

And can you try with your usual .emacs but deferring loading the desktop
file until you have seen your initial frame.

One thing that Robert can try is:

1) Put Emacs in the maximized state, or whatever is that is giving
trouble (just one frame).
2) Exit Emacs (saving the desktop)
3) Copy the "(setq desktop-saved-frameset ...)" line from .emacs.desktop
4) emacs -Q
5) paste the (setq desktop-saved-frameset ...) sexp into *scratch* and eval it
6) eval the following:
   (frameset-restore desktop-saved-frameset
                     :reuse-frames t
                     :cleanup-frames t
                     :force-onscreen t)

Then, repeat from 4) on, with the same desktop-saved-frameset value as
before, but call frameset-restore with :force-onscreen nil (or without
that line, nil is the default).

Assuming that the problem reappears doing that, at least we have a
frameset that causes it, and then we can look into it and try to
understand what happens.

I don't understand - was it Robert's problem that he wanted to save the
Emacs desktop with a maximized frame?  I only thought that _after
restoring_ the desktop, maximizing the frame didn't restore minibuffer
and title line.

So unless Robert says that this is the problem let's skip (1).

Robert please try here both variants with and without -Q so we can see
whether something in your .emacs has any impact.

Thanks.  This is what I had in mind with "deferring loading the desktop
file until you have seen your initial frame".

If we can repeat the problem this way, we can use the debugger.

You're correct, I was never attempting to save emacs' state with it maximised
so (1) can be skipped.

OK, I'm having problems at the moment getting it to replicate either
with a -Q -l loading:
     (desktop-save-mode 1)
     (setq desktop-save nil) ;; so that the desktop which was giving probs is kept!
     (desktop-read "/home/robert/tmp")

or with my normal .emacs will let you know when I manage to generate
the same problem again!

IIUC Juanma means that you must _not_ call `desktop-read' but rather
copy the

(setq desktop-saved-frameset ...)

form from your .emacs.desktop to *scratch* in the new emacs you just
started, evaluate that form and then do

    (frameset-restore desktop-saved-frameset
                      :reuse-frames t
                      :cleanup-frames t
                      :force-onscreen t)

in *scratch*.  If this does _not_ reproduce the problem after at most
two or three attempts I would conclude that the problem is with the
(Juanma might correct me) yet invisible frame used in the original
scenario by `desktop-read'.  For an invisible frame x_set_window_size_1
chooses the else clause in

   if (FRAME_VISIBLE_P (f))
     x_wait_for_event (f, ConfigureNotify);
   else
     {
       change_frame_size (f, width, height, 0, 1, 0, 1);
       x_sync (f);
     }

so there's no synchronization with the window manager right here and
maybe subsequently making the frame visible is not catching up with the
changes induced by change_frame_size.  This is the only conclusion I
currently have left.

So once more: If you can't reproduce the problem here with very few
attempts don't insist.  In this case we should try the following: Strip
your .emacs.desktop from any irrelevant entries.  This means to
construct a new .emacs.desktop that is sufficient to cause the original
problem and otherwise minimal enough so we can debug it.  Juanma: Can we
get a pretty printed version of Robert's .emacs.desktop such that he can
process it with `desktop-read' and we can comment out entries easily?
Then we could start in a first step do things like

;;      (foreground-color . "DarkOrchid1")
;;      (background-color . "mint cream")
;;      (mouse-color . "#221f1e")
;;      (border-color . "black")
;;      (screen-gamma)
;;      (line-spacing)
      (left-fringe . 8)
      (right-fringe . 8)
;;      (scroll-bar-foreground . "#221f1e")
;;      (scroll-bar-background . "grey75")
      (menu-bar-lines . 1)
      (tool-bar-lines . 1)
;;      (title)
      (wait-for-wm . t)
;;      (fullscreen)
      (tool-bar-position . top)
;;      (icon-type . t)
;;      (auto-raise)
;;      (auto-lower)
;;      (cursor-type . box)
      (scroll-bar-width . 16)
;;      (alpha . 90)
      (horizontal-scroll-bars . t)
;;      (display-type . color)
;;      (background-mode . light)
;;      (cursor-color . "#221f1e")
;;      (sticky)
;;      (environment)

Ideally we could comment out everything but the height and width entries
but I suppose we need some additional entry to produce the bug.  Any
such entry already should provide a first clue.

Correct. This is the way to know if it happens *after* the original
frame is created and visible.

> two or three attempts I would conclude that the problem is with the

And in that case, what I would suggest is to create a file

;;; bug17046.el ;;;
(setq desktop-saved-frameset ...)
(frameset-restore desktop-saved-frameset
                  :reuse-frames t
                  :cleanup-frames t
                  :force-onscreen t)
;;; end ;;;

and then try

   emacs -Q -l bug17046.el

(and the same with :force-onscreen nil).

Note: if the problem depends on the original frame having more than
one window (before the restore, I mean), then these windows should be
created in bug17046.el before calling `frameset-restore', of course.
Same for having several buffers, etc. But as a first test, the above
should suffice

I'm not sure which one right now, but assuming the last, which he said
showed the bug, the attached file should be enough.

One more question: Is there a way to have frameset make all changes only
with a strictly visible frame so we have all the flickering but can avoid
that

   if (FRAME_VISIBLE_P (f))
     x_wait_for_event (f, ConfigureNotify);
   else
     {
       change_frame_size (f, width, height, 0, 1, 0, 1);
       x_sync (f);
     }

restriction I mentioned earlier.

Please clarify. Do you mean:

- Not to restore upon a non-strictly visible frame (and so choose
another or create a new one)?
- To wait until the frame is visible?

(I'm not sure what do you mean with "strictly visible", BTW).

The :reuse-frames arg of `frameset-restore' accepts a predicate, so if
you have a way to decide from Elisp that a frame is "strictly
visible", you can allow or disallow its reusing.

The latter, I'd say.

"Strictly visible" should stand for "always visible while desktop
restoration is done".

I meant to find some way where we, before restoring a desktop, make the
involved frame visible and then do the restoring, so the user "sees"
what happens.  This obviously works only when a frame exists already
before restoration kicks in, but IIUC this is what happens in Robert's
case.

I'm lost. Why wouldn't it work to call (sit-for 0) before calling
frameset-restore?

Can I just step back a bit, having been doing other things, I'm 
rather confused as to what I'm being asked to do! I think before I
start doing to sequence of tests you've requested I need to get an
emacs which is showing a bad frame? At the moment I'm unable to
replicate this - if this isn't so let me know! But at the moment I'm
about to try generating another bad startup then I'll start on the
test at (2).  (your email of Sat, 22 Mar 2014 10:40:14 +0100) before I
start doing (setq desktop-saved-frameset etc

FWIW, I'm rather confused too... ;-)

Yes. If you restart your Emacs and get a bad frame, do not exit Emacs!
Immediately open the desktop file and get hold of the (setq
desktop-saved-frameset ...) line and save it in a safe place :-)

Then you can replace the equivalent line in my bug17046.el file with
yours, exit Emacs, and do the tests requested at your leisure.

The tests would be:

1) emacs -Q -l bug17046.el
2) Same, but replacing the ":force-onscreen t" by ":force-onscreen nil"
3) As 1), but insert  (sit-for 0) at the top of bug17046.el before the test
4) As 2), but with (sit-for 0) also, as in 3)

OK ignore the message I've just sent apart from the question about
whether the buffers mentioned in desktop-saved-frameset need to exist

They don't *need* to exist, but you can create them at the start of
the bug17046.el file and see whether that makes a difference. If the
saved frame has multiple windows and the buffers do not exist upon
restoring, you can end with a single-window frame. Perhaps that
affects the bug.

I've run these tests (and I kept the buggy frame emacs around while I
did so and I still have it, would attaching gdb to it give you anything
useful?) in this case the frame was displaying neither the decorations
nor the minibuffer

In all 4 cases I'm afraid the bug did *not* appear - I assume this is
what I was meant to look for with just a visual check. I also compared the
emacs frame with the buggy one (maybe you already realise this) and by
aligning the top of the menubar in each frame the buggy frame stops
just at the point where the buffer modeline should appear, looking
carefully I can just see the tops of the characters on the next line
of WikipediaApplet.cpp

Maybe I should add that in all cases (since I first saw the bug) I've
been running emacs from its build directory - so for me ~/emacs-bzr/src/emacs
(rather than installing it in /usr/local/bin)

I had the following lines at the head of bug17046.el

The fact that the bug didn't appear would be a good sign.  But I'm
afraid that you ran the experiment with the bad frame.  At least that is
what bug17046.el contains IIUC.  What we really have to do is to run the
experiment with the original two windows frame - I attached a hopefully
correct version of that.

I included one frameset from Robert's message, but in my instructions

Sorry.  I'm at least as much confused as you.

No.  We have to do something similar to restoring the frame which does
_not_ show the bad frame.  Let me try to explain (I'm afraid I'm not
very good at that).

With your original recipe you get a bad frame.  Unfortunately, we don't
know how to intercept that recipe, that is the frame restoration
procedure, in order to find out where things go wrong.  Nothing in the
dumps gives a useful hint.  Therefore we have to break up the original
monolithic recipe into various steps to find out where things go wrong.

Juanma's recipe is one such approach, simplified below:

(1) Copy the "(setq desktop-saved-frameset ...)" line from
     .emacs.desktop.  We presume that the inherent problem is somewhere
     hidden in that form.

(2) emacs -Q

(3) Paste the (setq desktop-saved-frameset ...) sexp into *scratch* and
     eval it.

(4) Eval the following:
    (frameset-restore desktop-saved-frameset
                      :reuse-frames t
                      :cleanup-frames t
                      :force-onscreen t)

Now apparently this fails as you mentioned in your other mail because
it's missing the remaining parts of .emacs.desktop like the buffers to
be shown in the windows.  I suppose this can be done easily by removing
just the

"(setq desktop-saved-frameset ...)"

form from .emas.desktop retaining everything else.  Please try to do
that, save the file but keep the original around, we might need it.
Then do (1)-(4) as above with one exception: Start emacs without the -Q
option in (2) to make sure the .emacs.desktop gets read.

Now this approach might produce a bad frame or not.  If it does, we can
proceed debugging `frameset-restore'.  If it doesn't after a few
attempts, stop testing.  Then we have restrained the problem to the fact
that `frameset-restore' breaks when working on the initial frame.

And before doing all this please wait until Juanma confirms that my new
recipe make sense at all.

Yes, though I prefer using "emacs -Q -l file.el" because desktop does
many other things, like trying to restore modes, global and local
variables, etc.

OK.  But the problem is IMO that Robert ran this with a frameset derived
from the a saved desktop of the bad frame.  This won't reproduce the
problem because that frameset is likely OK (I did not see any
inconsistencies in the frame dump at least).  We have to run this with a
frameset derived from the original two windows frame.  I hope I attached
a correct version in my last mail, please have a look.

Now if that frameset produces two windows as I expect, we know that the
problem is with transforming the initial Emacs frame, which apparently
is not good for restoring this desktop.  Then we have to step by step
remove lines from bug17046.el until we arrive at the line that causes
the problem.

The frameset in Juanma's bug17046.el file only appeared to have one
window (in as far as I understand the format!) and I've just tried all
4 tests with the file (& frameset) that was attached to his email (adding a
find-file of .emacs) and one window (onto .emacs) appears and no sign
of the problem

So I've tried it with your version of bug17046.el (now with 2 find-files)

This does produce 2 windows but in no case is there a sign of the
problem - or is that what you are expecting? I wondered about the

	(visibility . icon)

line (I don't think I ever started it up iconized) and tried the tests
both with and without it with the same result.

If I don't include the 2 find-files I get a single window onto *Messages*

Not sure whether it is relevant - or you've already assumed this
- there's no resize facility on the bad frame (apart from maximize) move
the mouse to the window corner and no resize arrows appear.

I wonder, too. A frame with visibility . icon *should* be restored
iconified (which will affect size, as the original height and width
are not restored in that case).

In fact, an iconified frame is restored as invisible, with default
size, and then modified to iconify it.

Easy to check.  Robert, in the original .emacs.dektop file change
(visibility . icon) to (visibility . t) and try whether you can
reproduce the problem by just starting emacs the usual way.

I did.  If you now ask yourself why I wanted you to try that, then it's
because I wanted to try with the more simple approaches first.  BTW, you
did check all four of Juanma's scenarios, that is also the ones without
the (sit-for 0)?

This is indeed a strange thing.  Juanma, do we usually ignore this?

It is yet another mysterious detail.  Please post now your entire
.emacs.desktop file here, that is the one that you use to produce the
bad frame in the new session.  I'll then try to tell you what to remove
from that file in order to narrow down the possible culprits.

Instead of (sit-for 0), I'd suggest trying with (read-event nil nil 1).

Definitely not. Try evaling this in emacs -Q:

(let* ((frame (make-frame '((visibility . icon))))
       (set (frameset-save (list frame))))
  (delete-frame frame)
  (read-event nil nil 1)

Aha!! adding (read-event nil nil 1) to bug17046.el instead of the
sit-for replicates the bug - it looks ok on startup but when I move
the mouse into the frame I lose the decorations and the minibuffer!

This is with

	  (visibility . t)
and :force-onscreen nil

This should give us something at last but I don't yet know what.  Please

File is attached, I hadn't seen this problem before my bzr update and
build of March 14th but I've just tried the same minimal startup with my
previous build of Dec 23 2013 (though as I'm running it from the bzr
pull area, it has the bzr updated el files) and I see the same problem.

I also get the bug with :force-onscreen set to t

Yes - the frame appears ok until I move the mouse into the frame (I'm
using focus follows mouse) when the decorations & minibuffer vanish.

And I still get the problem when I comment out the 2 find-files and
replace the buffer names further down the file with *scratch* and *Messages* -
so avoiding the loading lots of cc* libraries

Fine.  I wanted to ask you to do exactly that.  I attach a more
radically stripped file now.  If it works, that is if you still the
usual bad frame and no other bug is thrown, then try to comment out the
"font..." entries one by one.

BTW, if I follow my last suggestion here I get

With your attached file I get:

     Error (frameset): Wrong type argument: listp, vc

but also see the frame going bad, and the bad frames continue when I
successively comment out these lines and restart ignoring the above error.

OK.  Apparently the "vc" is needed and most of the window entries too.
I attach the minimal file that works here as bug17046-c.el.  Can you
confirm that the bug still occurs with that file?

This file doesn't produce the bug for me - and it only displays one

Which file: bug17046-c.el or bug17046-d.el?  What about the other?
(I suppose you received my last message earlier so if this is about
bug17046-d.el then please wait until you tried with bug17046-c.el.)

Neither bug17046-c.el nor bug17046-d.el produce the buggy frame
and both only show one window on startup.

If you can reproduce it with *-b.el, which is quite short, please try
commenting out one by one some lines in the FRAME section (starting
with display, visibility and minibuffer, perhaps...).

When in the last bug17046-e.el I posted I comment out (visibility . t),
the root window is not split on Debian.  It is split on Windows.

I removed first the 3 font* lines - which we'd already seen made no
difference from bug17046-b.el - when I commented (display . ":0") that
made the difference and the amended file now displays the frame
correctly.

I tried commenting out the other 2 lines you suggested (each time just
that line commented) and in both cases the frame display was buggy.

The commenting 'display' version causes the frame to jump position to
the top LHS so I had to be careful to keep the mouse out of the way -
moving the mouse into the frame during startup appears to prevent the
bug appearing.

So I now have a version of that file with visibility and minibuffer
commented and display uncommented which still shows the bug.

I just tried on Debian and noticed that frameset throws more errors than
Windows when `desktop-saved-frameset' is not entirely complete.
Attached bug17046-e.el is the minimum version that works on my Debian.
Please try this.

Are you sure?  Then we almost found it.  You now have to only find the
decisive difference between the last bug17046-a.el or bug17046-b.el
version that caused the bug and bug17046-e.el.  To do that please

(1) Make sure you found a version that produced the bug and did not
     throw any other error.

(2) From that version one by one comment out a line that is not
     present in bug17046-e.el.

Ahh...  I didn't have that message yet.  What does

(frame-parameter nil 'display)

give in a normal emacs -Q session?  And what gives

(getenv "DISPLAY")

in such a session?

Shouldn't affect, but just in case...

Could you please retry with the same bug*.el that reproduces the bug, but adding

   :force-display t

to the frameset-restore call?

The bug still appears with both the (display... line being present and
:force-display t

However if I comment out the (display line but *leave in* the
:force-display t parameter - the bug is still present - so in this case
:force-display provokes the bug - it would have been ok without that
line.

Please try this:

- edit lisp/frameset.el, and in line 1149, change

   (eq (frame-parameter nil 'display)

to

   (equal (frame-parameter nil 'display)

save, compile frameset.el, and try again.

and saved and compiled but the bug is still present (tried with both
the display parameter and :force-display - uncommenting them separately).
So I can't see any change in behaviour.

bug#17046: 24.3.50; On startup emacs frame has no minibuffer or windows decorations

Aha. Well, it was a long shot. The change I suggested fixes a real
bug, whose consequence is to make frameset-restore to force the
current display onto the restored frames; but in you case, the
restored frame's display and the current frame's display are
identical, so forcing it shouldn't change anything, and it doesn't.

Please try the attached bug17046-b.el. It's the same you sent me, plus
some code at the start.

I need to see the content of *Messages* in the two cases (with and without bug).

Do you see any problem if, from emacs -Q, you evaluate the following
code in *scratch*?

(let ((frame (make-frame)))
  (discard-input)
  (read-event nil nil 1)
  (modify-frame-parameters frame '((tool-bar-lines . 0)

I don't see a problem in this case - and also there's no problem in
the case in your earlier email.

(I've kept the mod you gave me yesterday for frameset.el I assume that
as it's a bug fix it is not material to this)

If you mean the change from `eq' to `equal', yeah, it's OK.

Now, could you please modify the bug17046-b.el I gave you earlier, and
change line 33 from

  (cons '(visibility)

to

  (cons '(visibility . t)

and try again both tests (with and without '(display . ":0")).

Thanks,

A nice theory just hit the dirt. Bummer.

Please revert the previous change. (i.e., it should have "(cons
'(visibility)" again), and comment out the window-state-put call in
line 48. Let's see whether the bug happens when creating the frame, or
when we put the window-state.

So it doesn't depend on the window-state.

If you're not yet bored to death, please try with the attached .el
file. It should behave as in the previous cases, but I want to see the
real, final frame parameter list of the reused (buggy) frame and the
created (correct) one.

(Thanks for your patience, BTW)

Well, we're closing on it, yes. It happens on reusing, and seems
related to display, and does not depend on the windows it shows.
That's good to know.

Now, please cut the `let' from lines 23-30 and paste it at the end of
the function, just there:

    (when alt-cfg (modify-frame-parameters frame alt-cfg))
    ;;; paste the `let' here

bug#17046: 24.3.50; On startup emacs frame has no minibuffer or windows decorations

[Juanma Barranquero]

Interesting. There aren't that many differences between the frames.
The possibly significant ones:

(environment)
(height . 36)
(horizontall-scroll-bars . t)
(left . 896)
(window-system . x)

vs.

(height . 30)
(left . 0)

So I'd suggest adding them (the ones in the first group) one by one to
your bug17046.el, and repeat the tests. Comment out the `let' from the
previous message, there's no need to report the frame parameters now,
just whether some case fails / works when previously it would've
worked / failed instead.

Let's hope we find something that can explain the different behavior.

I'm assuming that because the ones in the first group appeared in the
buggy run and not in the other, I need to add these to the version
with (display...  commented out and see if the bug occurs? I added
them incrementally - (environment) and then (environment) and
(height...) and so on until all 4 were active and then ran with one of
them only active at a time and the bug did not appear (so 7 runs in all).

So there were, that's one error each ;-) though height was already
there in the parameters so my eye must have elided it, I've just tried
it with 36 (rather than 30) and that doesn't make the version without
display error.

I've done all 4 runs and none of them produced the bug! I assume this
isn't what you expected, I see some of the parameters to
frameset-restore are different.

I half-expected it.

Not just that, I've radically simplified `frameset--restore-frame'.

So if you do not see now the bug even with (display . ":0"), that
means that we can forget for now the other parameters and concentrate
on testing only display yes/no again.

Before I change anything more, if you happen to still have a bug*.el
file from previous tests where you were able to reproduce the bug, try
it using

(frameset-restore desktop-saved-frameset
                  :reuse-frames t
                  :force-display nil
                  :force-onscreen nil
                  :cleanup-frames t)

to call frameset-restore. I expect that you will still see the bug,
but if you don't, that will be interesting by itself.

Great. Now, could you please try with that same bug*c.el file, but
commenting out the line

    (push '(tool-bar-lines . 0) filtered-cfg)

near the top of frameset--restore-frame?

That's great news! Sort of... :-(

That line's here because on some systems (Windows, among others),

  (make-frame '((height . X)))

and

  (modify-frame-parameters (make-frame) '((height . X)))

do not give frames of the same height (that's bug#14795).

Apparently, in your system, modifying a frame size with
(tool-bar-lines . 0) triggers a window manager (or Emacs redisplay)
bug.

If you evaluate this in emacs -Q, does it fail too?

(let* ((default-frame-alist nil)
       (frame (make-frame '((width . 80) (height . 20))))
       (tool-bar-lines (frame-parameter frame 'tool-bar-lines)))
  (discard-input)
  (read-event nil nil 2)
  (modify-frame-parameters frame '((tool-bar-lines . 0) (width . 60)
(height . 25)))
  (modify-frame-parameters frame `((tool-bar-lines . ,tool-bar-lines))))

It doesn't cause the bug but if I drop those lines into a file and
load it from a -Q -l command line I then see the bug.

Sometimes when I run that elisp (from *scratch*) I see the frame come
up 80 width and it doesn't resize to 60 which seems odd (to me)

Not my area of expertise, but I'd bet a few eurocents both of these
must be caused by a race condition of some kind, where Emacs idea of
the frame state and the window manager's idea are desynchronized.
Creating and modifying frames is relatively slow. Bug#16967 is such a
case, on Windows.

> but if I drop those lines into a file and

That's wonderful, because we have finally decoupled the bug from
framesets (which makes things easier to test).

So, at the end, the bug is that modifying the dimensions of an
existing frame with tool-bar-lines set to 0 fails. That's either a
window manager problem, or a problem in the Emacs code related to it.

Adding a workaround for frameset.el is possible, but I'd like to know
if it's possible to fix the bug for real, because any workaround is
going to be ugly; I can't just disable the current code because I'd be
trading one bug for another.

Martin, any suggestion? Anyone else who knows about this stuff?

Since Robert uses GTK the toolbar is not part of the Emacs frame.  And
since IIUC the frame is not yet visible, the problem with applying the
frame size change immediately, that is without waiting for a
ConfigureNotify event, might have an impact too.  Why GTK+ would drop
the frame title is still beyond my comprehension.

Does it help to apply the size parameters only after the rest,
including the toolbar, were already applied, i.e. in a separate call
to modify-frame-parameters?

Do you mean to do this?

(let* ((default-frame-alist nil)
       (frame (make-frame '((width . 80) (height . 20))))
       (tool-bar-lines (frame-parameter frame 'tool-bar-lines)))
  (discard-input)
  (read-event nil nil 2)
  (modify-frame-parameters frame '((tool-bar-lines . 0)))
  (modify-frame-parameters frame '((width . 60) (height . 25)))
  (modify-frame-parameters frame `((tool-bar-lines . ,tool-bar-lines))))

Robert, could you try this, please? (In a separate .el file, as you did before)

Thanks.

I read Eli's suggestion as

  (modify-frame-parameters frame `((tool-bar-lines . ,tool-bar-lines)))
  (modify-frame-parameters frame '((width . 60)
				   (height . 25))))

which doesn't show the bug, In your order with those 2 calls swapped
around the bug is present.

Though I was also uncertain as to whether implementation internals
were being referred to.

The local binding for tool-bar-lines in my test code is the value of
the tool-bar-lines parameter of the freshly created frame (for
example, on my system its value is 3). So the code above would not
show the bug because it is not setting tool-bar-lines to 0.

So unfortunately Eli's idea didn't work.

Does it fail/work with these additional read-event's? (To allow redisplay)

(let* ((default-frame-alist nil)
       (frame (make-frame '((width . 80) (height . 20))))
       (tool-bar-lines (frame-parameter frame 'tool-bar-lines)))
  (discard-input)
  (read-event nil nil 2)
  (modify-frame-parameters frame '((tool-bar-lines . 0)))
  (read-event nil nil 0.1)
  (modify-frame-parameters frame '((width . 60) (height . 25)))
  (read-event nil nil 0.1)
  (modify-frame-parameters frame `((tool-bar-lines . ,tool-bar-lines))))

My idea was what Robert did.  So it did work ;-)

Is it for some reason unworkable to have the size change after all the
rest?

Oh :-)

But that's equivalent to just skipping all the hoopla with
tool-bar-lines. You're setting it to 0, then to the correct value, and
then modifying the frame.

> Is it for some reason unworkable to have the size change after all the

Presumably, that would break the fix for bug#14795.

OTOH, though the bug still real, i.e.,

  (modify-frame-parameters (make-frame) '((height . X)))

and

  (make-frame '((height . X)))

give frames of different size, now I cannot reproduce the problem when
restoring frames with frameset-restore *without* my workaround.

I think there's been some changes related to frames and the like, so
it is possible that the workaround can simply be removed and this
problem just disappears. We would still have a bug with GTK builds and
tool-bar-lines = 0, but it would be of much lesser impact.

Allow me a few hours to test things thoroughly.

Bootstrap failures are usually noticed quite soon. Was this the trunk
or the emacs-24 branch?

I just bootstrapped both trunk and emacs-24 without any trouble.
Perhaps it is a POSIX-specific failure.

I'd suggest cleaning up the workspace (with bzr clean-tree),
reconfiguring and bootstrapping again.

Thanks for doing that check - I assume as I've not done anything
special (that's emacs-24 orientated) that I'm on the trunk.

OK, now I understand.

I originally added the tool-bar-lines stuff as a workaround for
bug#14795, which affects only newly created frames. That means that if
the frameset has a (height . 20) parameter for frame A, when restoring
the frameset, reusing a frame for A would work, but in case reusing
failed (no suitable frame found), A would be created with more than 20
lines (23 on Windows, for example). So the tool-bar-lines fix, to get
A back to 20 lines.

For several reasons related to offscreen frames, it turns out when a
new frame is needed, frameset-restore creates it invisible and
onscreen, and then reapplies its frame parameters and turns it visible
(if required). Which means that every new frame (the ones affected by
bug#14795) is already resized to the correct height while invisible,
regardless of whether it was the right height or not to start with.

In other words, I can remove the workaround for bug#14795 because it
is unnecessary now.

The GTK bug with (tool-bar-lines . 0) should be filed as a new bug,
IMHO, perhaps with a pointer to this one.

Can you confirm that the desktop being used to load is (by default)
the one in $HOME (if it exists) and not any in the current directory
(I saw it writing the desktop to ~/ just wanted to be sure it read
from there too as I'd squirreled one away in ~/tmp which is where I
was running the tests from)

Are you sure? My desktop file contains 266 calls to
desktop-create-buffer - (slight diversion/scare here[1] ) Can I make it
available via the web or do you want it in the body of the bug thread?

Is there any trimming down I can try first - removal of buffers in
same mode with same minor modes?

> And thanks for bearing with me, martin

Thanks for your efforts!

Robert
[1] it looks as if it has been overwritten?  I've got another emacs
session (where I'm typing this) but as I haven't closed any buffers it
should be the same (or re-ordered), I thought .emacs.desktop was only
written on exit - it looks as if the desktop-auto-save is the new
default. Looks like I'm going to have to verify .... yes it's still
bad - and now saved elsewhere!

Variable desktop-path shows the list of directories to search for the

I did all those (2,3 then 4-6) -the desktop-saved-frameset referenced buffers that
didn't exist - is that correct or should I have loaded them before
evaling the desktop-saved-frameset?

Then repeated (4-6) with :force-onscreen now nil

In neither case did the problem appear. What I am seeing on emacs -Q is

Ignoring unknown mode `16-mode'
Ignoring unknown mode `16-*-*-mode'

in *messages* - is this benign? They don't appear with -Q --no-site-file
but *info* says that -Q covers --no-site-file?

No both in the 'maximized' state and on restored the window is exactly
the same (though in a different position relative to the rest of the
screen). The one difference is that the emacs frame which was
originally showing two windows now only shows one window. I'm
including a screenshot of the maximised state. Other applications
maximise as expected - as does emacs when the desktop isn't loaded.
(I commented in a previous message that maximise isn't working
properly when the frame is in this state).

The attachment can be viewed here:

  http://debbugs.gnu.org/cgi/bugreport.cgi?msg=65;filename=maxim.png;att=1;bug=17046


Is the maximise state happening but the border is only giving a
partial window and the other buffer is there but the frame cuts off
visibility?

Exactly the same behaviour as in case (1)

I exited the bad state emacs but with only one window shown in the
frame and then restarted emacs and the frame was displayed correctly!
I then displayed another buffer in a second window in that frame and
exited again. On a restart the problem was back.
The problem only seems to occur when the frame is trying to show 2
buffers?

If you start Emacs with

  (setq desktop-restore-frames nil)
  (desktop-mode 1)

does still happen? (Perhaps desktop is restoring a frame with some
weird parameters...)

Yes that solves the problem - (assuming you meant (desktop-save-mode 1) ) 
- there only though appeared to be one frame when the faulty
restore happened - and the problem occurred more than once - in both
cases I was exiting (and implicitly saving the desktop) when only
one frame was open (at least as far as I could see!).

Yes, desktop-save-mode.

Please edit your .emacs.desktop file and remove the assignment to
desktop-saved-frameset in the "Global Section". Then reenable
desktop-restore-frames in your .emacs and let's see if the issue does
reappear. If it does, I'd suggest posting the contents of
desktop-saved-frameset (from the desktop file).

I carried out the above and the issue does not reappear (I tried
maximise and unmaximise a couple of times just to check) so I'm
assuming you meant that the contents of desktop-saved-frameset was the
problem which I include below - unless my suggest in my contribution

It is possible that a frame in some weird state was saved, and from
that moment on, exiting/entering Emacs with desktop-mode enabled would
try to reproduce that weird frame (or window) state from the saved
frameset.

The frameset dump you sent includes two frames. It is the one that was
giving you trouble? At a cursory look, I don't see anything obviously
wrong with the frames. Martin, do you see something questionable in
the window trees?

I see two issues:

FRAME 2

Obviously a total-height of 0 for FRAME 1 is broken - it should look
like for FRAME 2.  Just that a total height of zero shouldn't have any
bad consequences - it would get swallowed by `split-window'.  And the
differences in frameset--mini, are they OK?

I checked, and it doesn't cause any trouble when restoring.

Yes. The first t means that the frames have their own minibuffer. The
second t means that that frame's minibuffer was the one pointed out by
the `default-minibuffer-frame' variable. When restoring,
default-minibuffer-frame will be set to that frame, but that would
only affect new minibufferless frames, so it doesn't seem to have any
influence in the reported bug.

I wonder how this 0 crept in tho.  The pixel-height is completely
normal.

BTW, how do you handle maximization and fullscreen, I'm too lazy to look
at the code.  Do you handle the 'maximized frame parameter?

As far as I can see, fullboth and maximized are preserved (ie. a
fullboth frame is restored as fullboth, and a maximized one is
restored as maximized).

But what about a frame that has both parameters set - fullscreen and
maximized?  IIUC a fullscreen/fullboth and maximized/maximized one will
become fullboth and de-fullscreenifying it will make it normal.  Right?

Now you got me. What's that "maximized" parameter? I've never seen it.
The docs only talk about having (fullscreen . maximized).

IIUC it's a kludge Eli introduced on w32 to handle the case where we
toggle via F11 from a maximized to a fullscreen frame and via another
F11 back to the maximized (instead of a normal) one.  So you should see
the `maximized' parameter after you applied F11 to a maximized frame.

I have understood the idea but not yet whether it works in all cases.
And I suppose it should not concern desktop.

But it is a w32-specific hack? Because Robert's frameset contains
(maximized), but he's on Ubuntu.

I did?  There's not a single line of my code in w32term.c, under
SIZE_MAXIMIZED, where this parameter is used.  That code was added by
your revision 115301, AFAICS.

Perhaps you mean the FULLSCREEN_MAXIMIZED value of the
f->want_fullscreen slot.  But that isn't my invention, either, nor is
it w32-specific.

Sorry.  I forgot.

No.  That one is about what should be done.  The one I referred to is
about what should be restored when we toggle fullscreen mode off - a
maximized or a normal window.

Having both is an error.
We should have only one parameter.  It's too late to fix it 24.4, but we
should fix it for 24.5.

I think this parameter should be called `maximized' with values:

  nil
  width
  height
  t
  fullscreen

Is there some situation that is not covered by the above?

Yes.  On GNU/Linux maximize your frame, then type F11 twice.  What you
get is a maximized frame.  I presume this is the desired behavior.  To
get the same behavior on Windows you have to remember the state before
typing F11 the first time.

Note that F11 is not covered by the Windows API.  It's the application
that calculates the sizes and asks Windows to apply them, but as far as
Windows is concerned, a fullscreen is just the same as a normal window.
Now when we leave fullscreen mode we must somehow know whether to
restore to a maximized or a normal frame.  That's what the `maximized'
parameter is for - it remembers the previous state.
