Options menu is broken on CVS

Options menu is broken on CVS

[İsmail Dönmez]

Hi all,

Options menu no longer works with emacs from CVS. To reproduce open emacs 
press F10->O and you get :

Symbol's value as variable is void: menu-updating-frame

Looks like recent changes to lisp/menu-bar.el borked this though I am not 100% 
certain with that. So wondering if anyone can reproduce this?

Regards,
ismail

I don't see this problem on GNU/Linux.

menu-updating-frame is a builtin variable.  If you use M-x report-emacs-bug
(its on the menu-bar!) we can see how your Emacs was built and perhaps why
menu-updating-frame has been seemingly left out.

It _was_ for a reason.  The 2 related changes I committed at that time
were these:

2004-03-13  Eli Zaretskii  <eliz@gnu.org>

	* Makefile.in (XMENU_OBJ): Include xmenu.o if HAVE_MENUS is defined.

	* emacs.c (main): Call syms_of_xmenu only if HAVE_MENUS is defined.

I don't remember the details (you will probably find them in
emacs-devel or emacs-pretest-bug archives for that period of time),
but there was some build failure, I think on MacOS, which these
changes were part of fixing.

Please don't take out this change without understanding what it was
fixing in the first place.

Is there a way to fix this for non-X users of emacs ?

Sorry, I don't understand: what is that ``this'' which you want to be
fixed?  If that's the tmm problem, it _will_ be fixed, we just need to
find a way to do that without breaking whatever it was that my change
back in 2004 fixed.

Problem is F10->O no longer works in emacs configured with --without-x . And 
as far as I can tell its a more recent change than in 2004 as I am using 
emacs cvs for long and this problem is new.

If you have the X libraries you can compile with X and use it in terminal
mode (emacs -nw).

Have you've always configured without X or just used Emacs in terminal mode?

I think this is the right fix.  Actually I think the problem was caused by
Kim's change:

2004-03-11  Kim F. Storm  <storm@cua.dk>

	* Makefile.in:...
	(XMENU_OBJ) [HAVE_MENUS]: Move declaration to proper place.

The preamble for xmenu.c says:

/* X Communication module for terminals which understand the X protocol.

but xmenu.c is more general than that and compiles without X.  Even its
name is misleading (as with xdisp.c which also compiles without X).

Please describe the reasons why you think this is the right fix.  (I'm
assuming you've read the discussions from 2004 that led to the
original changes.)

That change was made for a reason as well: some problem on Carbon.  We
need to understand that problem, to be sure your change will not
reintroduce it.  I hope that the explanations I asked for above will
clarify this (I still didn't have time to re-read those past
discussions and retrace what problems we were trying to fix.)

In addition, we need to explain why the OP says he started to see the
problem only recently.

That's history: xmenu.c was originally written for X, but then menu
support was added to the DOS port and later came tmm.  If you think
the name xmenu tricked Kim and myself into thinking it's only for X,
that was not the reason.

menu-updating-buffers is defined in syms_of_xmenu ().  Currently syms_of_xmenu
is only called in emacs.c if HAVE_MENUS is true.  menu-updating-buffers is
needed even if Emacs is configured without X (on GNU/Linux at least) but in
this case HAVE_MENUS is not defined.

xmenu.c is needed even HAVE_X_WINDOWS is not defined so I've moved it outside
the conditional requiring it.

I might not have followed it all but your change seemed to cover Carbon Emacs
which it still does:

#ifndef HAVE_CARBON
XMENU_OBJ = xmenu.o
#endif

Now I've moved it outside #ifdef HAVE_X_WINDOWS you might need to add
another condition for when w32menu.o is used, I'm not sure.

I didn't find the discussion that led to this change.  It might have been
part of a general tidying process.

I've tried to explain that in another post: more calls to menu-updating-frame
have been made in menu-bar.el (26/08/05).

I don't have an opinion on whether you or Kim were tricked, just that the
description is misleading and that xmenu.c is needed even HAVE_X_WINDOWS is
not defined.

Thanks.

However, this is not what I asked; the reasons why symbols defined in
syms_of_xmenu are void unless xmenu.o is linked in are perfectly
clear.  Sorry for not being more clear.

What I meant is to have an explanation why your change solves the same
problem which caused Kim and myself to place XMENU_OBJ in a different
place, without breaking other ports and configurations.  That would
require to understand the original problem, which had something to do
with Carbon.

That's exactly the breakage I was afraid of.

No, it was to solve a very specific issue with Carbon.  Okay, I will
try to dig into this over the weekend.  Solution for non-X builds will
have to wait until then.

The relevant pieces of information are here:

  http://lists.gnu.org/archive/html/emacs-pretest-bug/2004-03/msg00132.html
  http://lists.gnu.org/archive/html/emacs-devel/2004-03/msg00231.html

and in the ensuing threads.  In essence, the events unrolled as
follows:

  . Kim moved XMENU_OBJ to a different place (I'm not quite sure why,
    but it had something to do with consolidating image support on
    different systems, see Kim's src/ChangeLog entries for
    2004-03-11).

  . This broke the --without-x build on Unix and GNU systems, since
    xmenu.o was not being linked in.  See the first thread above.

  . I fixed this on 2004-03-13 by adding XMENU_OBJ to the non-X
    branch, conditioned on HAVE_MENUS.

  . This broke the Carbon non-X build, since xmenu.o does not compile
    on Carbon.  (See the second thread above.)  The fix was to
    condition xmenu.o inclusion in the non-X case by HAVE_CARBON _not_
    being defined.

The result of all this was that xmenu.o was being linked in both in
the X and in the non-X branches, and in both cases it was conditioned
on HAVE_MENUS being defined and HAVE_CARBON not being defined (because
Carbon uses macmenu.o instead).

Now, your suggested change simply moves the first instance of xmenu.o
outside the X branch and also outside the HAVE_MENUS condition (and
does nothing for the second instance, btw).  Why is that the right
thing?  I think the non-X build on Unix and GNU systems doesn't define
HAVE_MENUS for a reason: without the proper X11 headers and libraries,
xmenu.c simply will not compile.

Moreover, I have a non-X Emacs built out of CVS of June 11 2005, and
F11->o works there without any problems, although I verified that
xmenu.o was not linked in (in fact, there's no xmenu.o at all there,
since xmenu.c was not compiled).

My interim conclusion is that the changes back in 2004 were not the
one that caused the current problem.  I will dig some more to
understand what is the real cause of that, and describe my findings
here.

Meanwhile, I don't think we should apply your suggested changes, since
compiling xmenu.c on a system without X headers and libraries might
fail due to unresolved externals.

I think the second instance could be removed.

It seems to work for -with/without-x and probably for proprietary systems
too.

I'm not sure what HAVE_MENUS means but non-X systems clearly have menus
(perhaps you've been tricked!). However, xmenu.c _does_ compile without
X11 headers and libraries, otherwise you couldn't make a non-X build with
it.

The OP said F10->O didn't work whatever that means.  F10->o does work because
it doesn't use menu-updating-frames.  Try, for example F10->f with your copy,
I don't think that will work.

I think you are wrong.

It solved the OP's problem.  I suggest that we do apply it as thats the only
way to test it.  If it is wrong, I am sure we will hear about it shortly.

HAVE_MENUS means menu support on the C level.  tmm doesn't do that, it
_emulates_ menus on the Lisp level.

If the headers and libraries are present on the system, you could
build such a version allright.

Well, I think my patch just installed proves that I am right.

No need, as I fixed that differently.

OK.  I see now.

xmenu.c compiles without X libraries (--without-x doesn't link to them) but
now I think that the non-X build on Unix and GNU systems doesn't define
HAVE_MENUS because it shouldn't need xmenu.c

Yes, I think your change is generally right, non-X builds don't seem to use
menu-updating-frame (it's always nil if defined).

However you have missed some references to menu-updating-frame.  For example
F10->f doesn't work beacuse of:

(put 'dired 'menu-enable
     '(not (window-minibuffer-p (frame-selected-window menu-updating-frame))))

You might also need display-multi-frame-p in kill-this-buffer-enabled-p.

What you say is not detailed enough, because xmenu.c has 2 different
parts (one with USE_X_TOOLKIT, the other without it), and some
additional preprocessor directives partition the code there still
more, depending on whether you use GTK, Lucid, Motif/LessTif, etc.
Which one of these variants did you try to compile?

At least the non-toolkit version of the functioon xmenu_show (the one
near the end of xmenu.c) uses functions like XMenuCreate,
XMenuAddPane, XMenuDestroy, etc., and constants like XM_SUCCESS and
XM_FAILURE, which will cause failures either during compilation or
during linking, if X headers and libraries are not available/linked
in.

Done.  I also took this opportunity to add to menu-bar.el 2
subroutines that check the menu frame for being live and visible, and
check that the selected window on that frame is not a minibuffer
window.  The `:enable' clauses of the menu bar items now use these two
subroutines instead of in-lining their guts.

I debugged this.  It's like you said earlier in this thread:

  This change

  2005-08-26  David Reitter  <david.reitter@gmail.com>

	  * menu-bar.el (truncate-lines, write-file, print-buffer)
	  (ps-print-buffer-faces, ps-print-buffer, split-window):
	  Disable menu items when the frame they refer to is invisible, or when
	  they refer to a buffer and the minibuffer is selected.

  will break things if you try to access one of these functions from the menubar
  having configured --without-x.

The problem is indeed that this change caused the menus to reference
menu-updating-frame, which is not defined in the non-X version.

I installed a change that avoids referencing that variable on
non-multiframe displays.  Ismail, please check that the new version
works for you.

Uh, ttys _are_ multiframe in some manner (one can create and delete
frames).  That's pure Lisp level, then?

Yes, I know (I wrote large parts of that code ;-).  However, I meant
those displays that can show only one frame at a time (those for which
display-multi-frame-p returns nil).

> That's pure Lisp level, then?

No, the support for multiple tty frames is in frame.c (see
Fmake_terminal_frame and friends).

Besides menu-updating-frame, tmm.el uses x-popup-menu (defined in
xmenu.c) in order to obtain keyboard equivalents.

           (condition-case nil
               (x-popup-menu nil choice) ; Get the shortcuts
             (error nil))

Because it is enclosed with condition-case, we don't see any errors
with it.  But keyboard equivalents are not shown with tmm for the
non-X version where xmenu.o is not linked.  I confirmed that they were
shown for the non-X version with the Nick's patch.

I don't think it's right to compile and link in xmenu.c on platforms
where menus are not supported on the C level.  If we want to show
keyboard equivalents in tmm, we should find another way of gleaning
them, without calling x-popup-menu.

I see no reason to duplicate this code.  If x-popup-menu can operate
at run time, for this limited purpose, without a window system, it
should not be hard to make it do the same job when compiled without a
window system.

I have no idea if this will work without some non-trivial re-shuffling
of the code in x-popup-menu.  Just looking at the source, it seems to
invoke functions that need X (or its emulation).  Someone will have to
work on refactoring the code before we can do what you suggest.

The following changes seem to be enough to make x-popup-menu compile
and link properly.  And the keyboard shortcuts do appear.

Note that no change was needed in xmenu.c itself.  Apparently
someone already prepared that file for such use.

Agreed.  If that's possible, of course (I see that both w32menu.c and
macmenu.c hold quite a lot of code).

The current macmenu.c is based on old xmenu.c (or w32menu.c) code.  I
have some backlog that makes macmenu.c synchronized with xmenu.c.
Shall I install it?

Re: Options menu is broken on CVS

    but xmenu.c is more general than that and compiles without X.  Even its
    name is misleading (as with xdisp.c which also compiles without X).

When I made the file name xdisp.c, I had not yet heard about X Windows.
I put in that file the code for the guts of display that I had rewritten.

Re: Options menu is broken on CVS

    It seems to be due to this change:

    2004-03-13  Eli Zaretskii  <eliz@gnu.org>

	    * emacs.c (main): Call syms_of_xmenu only if HAVE_MENUS is defined.

    I guess it hasn't been noticed before because, although people may use tmm,
    most use a version of Emacs thats compiled with X (or at least HAVE_MENUS).

    I haven't reverted this change because it must be there for a reason.  Eli?

Eli is surely right that this change fixed a bug.  However, this shows
that the bug has to be fixed a different way.

Perhaps the best way to find out what the bug was is to revert the
change; then someone will see that bug again, and someone can write a
new fix for it.

No, this is IMHO a bad way: the chances of that someone to see that
bug could be small, depending on what was the configuration in which
it was found back then.  It is much better to read the emacs-devel
discussions related to my change and understand what was the bug I
fixed.

Let's take it as a reminder that when we commit a fix, we should make sure
we describe the bug it fixes, either in comments in the code (when
possible/meaningful) or in the ChangeLog entry.  Of course, if the old code
was just plain wrong it's not necessary.

Alas, there's no machinery in GNU coding/development standards to
record such information.  In Emacs, we don't even have a bug
repository to which one can refer, like "see bug #12345" or some such
(a reference to the mail-list thread might serve as a replacement, but
only if the problem was discussed publicly in enough detail).  A
description of a bug with enough info to reproduce it later could take
a lot of text, and it's IMHO impractical to put all that text in the
source files or in the logs.

In addition, there are situations where you don't have a good place to
put a comment, e.g. if the fix was to _delete_ something.

> Of course, if the old code was just plain wrong it's not necessary.

``Plain wrong'' is in the eyes of the beholder.  Such judgment calls
are part of the problem: what's ``plain wrong and doesn't need any
explanation'' so some, is a mystery to others.

Even if we had a bug repository, I'd prefer a longish text, so you don't
need to refer to the bug database to know what it is.  The only alternative
would be if the bug database is stored alongside the source files.

> In addition, there are situations where you don't have a good place to

You can replace the deleted code with the comment (of course, only if the
location of the comment makes sense: if you delete a whole function at the
toplevel, replacing it with a toplevel comment won't be much help), or you
can put the info in the ChangeLog.
It's a fundamental problem and there's not much we can do about that, really.

I agree that inserting the full text in the code or ChangeLog would be
too much.

Why not turn on the bug page at http://savannah.gnu.org/projects/emacs/?

Referencing bug numbers in the ChangeLog is short and easy and makes
it easy to refer to the full dialog of the issue. The Savannah bug
repository also makes it really easy to create release notes in a form
which makes it easy for a user to see if their bug was fixed or
feature implemented.

Note that bug reports can (and should) be forwarded to a mailing list
(such as emacs-devel) so that people are aware of them. I don't know
if Savannah has the ability to append comments to a bug report via
mail, but since the URL is in each message, it is easy enough to click
on the link and enter the comment on the web form.

That inconvenience is far outweighed by the advantages of a bug
tracking system. Bug reports and feature requests can't get forgotten
as they might on a mailing list.

I had expected to find a discussion about this already, but I couldn't
find one.

The bug tracking system on savannah is _really_ bad (or at least it
was the last time I tried to use it in earnest). Regardless of how
useful it is in theory, if it's annoying and inconvenient to use, it
will see little use.  This is especially true when the bulk of work is
done by volunteers who want to spend what little time they have on
coding.

    Why not turn on the bug page at http://savannah.gnu.org/projects/emacs/?

What other work would we have to do to actually make use of it?

Re: Options menu is broken on CVS

    You can replace the deleted code with the comment (of course, only if the
    location of the comment makes sense: if you delete a whole function at the
    toplevel, replacing it with a toplevel comment won't be much help), or you
    can put the info in the ChangeLog.
    It's a fundamental problem and there's not much we can do about that, really.

I'd rather have explanations in comments in the code than in
ChangeLog.  In the code, it is easier to see.  If the change was to delete
a function, and it needs an explanation, you could put the explanation where
the function used to be called.

In ChangeLog it can be useful to mention the date and sender of the
bug report.  That would be brief, but enough to find the discussion
straightforwardly.

If the discussion was in a public mailing list, a URL of the message
that started the thread would IMHO be a better way of pointing to it.
Unfortunately, some bugs are discussed in private email.

    that started the thread would IMHO be a better way of pointing to it.

The date and sender are in the message--the URL is not.  It would be
too difficult to find the URLs and put them in the change log.
(Would you want to find the URLs for me?)

Refering to bug reports (was: Options menu is broken on CVS)

I'd suggest to add the Message-ID (maybe in addition to sender and
date).  Gnus can fetch messages by Message-ID both from local and
public archives.  I'd supposed that also Rmail could also do this.
(Followups can be found by searching the References header.)

The mailing list archive Gmane.org (run by Lars Ingebrigtsen) where
most Emacs related list are archived also provides the possibility to
find messages and thread by Message-ID, e.g.:

  http://mid.gmane.org/E1EELj8-0006vJ-6e@fencepost.gnu.org
  http://thread.gmane.org/E1EELj8-0006vJ-6e@fencepost.gnu.org

Another option would be that the mailing list software adds an
"Archived-At: URL"[1] header pointing to the archive.  I don't know if
the mailing list software can be configured to do this.

That is feasible.

Given the date and the Subject, it should be very easy to do that,
using the mail-archive Search command.

For me, this is not merely hard, but impossible.  I do my work without
internet access, most of the time.

A clean CVS checkout compiled with make bootstrap is showing the same problem.
