Dear Bug Team!
I found this problem using git mode when adding a new directory (which
isn't supported in git.el). I can reproduce the crash using the
following steps with xemacs -vanilla:
(load "emacs-simple")
C-x b *foo*
<insert a couple of lines of text into *foo*>
M-: (display-message-or-buffer (get-buffer "*foo*"))
This causes a crash in count-screen-lines on line 42 of the file.

Hi,
Some strange things in your report I'm afraid.
I found this problem using git mode when adding a new directory
(which
isn't supported in git.el). I can reproduce the crash using the
following steps with xemacs -vanilla:
(load "emacs-simple")
What is emacs-simple? I don't have it? Is that somehow related to
git.el[1] (which I don't have either.)
[...]
M-: (display-message-or-buffer (get-buffer "*foo*"))
We don't have display-message-or-buffer[2].
So it is quite hard to recreate this problem I'm afraid.
Yours
Footnotes:
[1] Is git.el a candidate to include in the packages
[2] Should we implement it?

Dang. Did I forget to attach emacs-simple? It's attached now. :-)
Yes, it's related to git.el. To add a new file, git.el needs
display-message-or-buffer, which I stole from emacs-simple.el. Since
I didn't need all of the functionality of emacs-simple, I removed
everything except display-message-or-buffer.

Sorry about that. I think I've attached everything needed to
reproduce.

Mats> Footnotes:
Mats> [1] Is git.el a candidate to include in the packages
I like it a lot. As a long-time user of pcl-cvs, git.el is a very
familiar interface to work with a git repo. Except for the crash, I
think the functionality is fairly complete, if you're used to
pcl-cvs. There are a few bugs, though, that I haven't gotten around
to fixing. (Or upgrading git.el)
Mats> [2] Should we implement it?
I guess it's a part of emacs, so it might be useful. The attached
emacs-simple.el file is (I think) an unchanged version from emacs.

Or maybe not. Why didn't gnus C-c C-a attach the file? Let's try that again
with text/plain instead of application/emacs-lisp.
And just in case, I'm pasting the relatively small file that just
contains display-message-or-buffer directly too.

I can recreate your crash. It is an assertion that fires:
Fatal error: assertion failed, file indent.c, line 626, elt >= 0
Unfortunately I have no more time this evening to look into
this. Maybe tomorrow but feel free to debug this further, anyone!

Let's try that again

It probably did, and it gets removed by Mailman. Emacs Lisp source is
a text/* format -- humans can read it without anything more
sophisticated than a POSIX cat(1). application/emacs-lisp means to
process the code with the application "emacs-lisp". I just prohibit
application/* on XEmacs lists, because no application/* type (except
Gnus' wrong-headed and non-standard application/emacs-lisp) is useful
to us.
I know Gnus people think otherwise, but I don't really care what they
think.:-)

I'm guessing that this is a file containing functions implemented in
GNU Emacs that aren't in XEmacs. If so:
Did you byte-compile this file with the XEmacs you're using? If you
use an .elc compiled by 21.5 in a 21.4, or an .elc compiled by GNU in
any XEmacs, I wouldn't be surprised if you can crash XEmacs.
[1] Is git.el a candidate to include in the packages
AFAIK the git mode preferred by 9 out of 10 dentists is magit.el.
That doesn't mean we couldn't offer both, but I guess I would put
priority on magit if you're asking my opinion. (Of course the mode
with a volunteer to maintain it will win, or at least get in first!)
[2] Should we implement [display-message-or-buffer]?
I think it's a function we'd be better off without. The idea is that
you can pass an arbitrarily long message as a string or a buffer, and
it will either display in the echo area if short "enough", or pop up a
buffer. But the arguments are crufty, the functionality is basically
available with `message' and C-x b " *Message-Log*" RET, and probably
improving with-displaying-help-buffer and friends would be a better
way to implement the basic idea.
Of course if there's enough code using the function we probably need
to implement it in the name of compatibility.

I'm a die-hard xemacs user[1]. I don't think I've used GNU emacs since
the pre-lemacs days. I haven't used 21.4 since 21.5 came out oh so
many years ago, except occasionally on Windows. :-)
> [1] Is git.el a candidate to include in the packages

That's possible, but when I went looking for a git mode a few years
ago, magit.el didn't work for me or was different enough from pcl-cvs
that I didn't like it. (Too many years working with cvs and pcl-cvs,
I guess.)
Ray
[1] I sometimes think about and try switching, but it's different
enough from xemacs and my customizations that I don't stay. The
only functionality that I find missing is better font-lock. (SLIME
will cause xemacs to hang when I insert #+nil into lisp code. It
has something to do with missing functionality in xemacs font-lock
implementation.)

Decided to revisit magit. Doesn't work out of the box.
Requires 'view. I assume that's roughly equivalent to view-less.
Requires 'ido. There seems to be no equivalent, but the emacs version
of ido.el appears to mostly work once you fix up the defface things
like:
(defface ido-first-match '((t :weight bold))
"Face used by ido for highlighting first match."
:group 'ido)
to
(defface ido-first-match '((t (:weight bold)))
"Face used by ido for highlighting first match."
:group 'ido)
Requires 'server. I assumed it was equivalent to gnuserv, and
modified a few places to use gnuserve* instead of server*.
Now I'm stuck. It wants process-file and I don't know the xemacs
equivalent of that.

Well, if you don't have one yet and you can try git.el. It does
everything I want it to do (fairly limited). The only thing that's
missing is that git.el wants sdiff to handle unmerged files and I
haven't done anything about that. Oh, and also the bad bug where
trying to add a directory causes xemacs to crash. :-(

Look for a file handler defined in the magit code with key
'process-file. If there isn't one, then basically it's call-process.
However, Emacs has a different way of handling stderr from XEmacs, and
that may be the source of the error. Just for kicks, the code for
process-file is appended below.

AFAIK we can just drop in sdiff somewhere, probably in ediff but maybe
in prog-utils. At least at one point it seemed to work OK in XEmacs.
Have you reported and provided a backtrace for the crash? It doesn't
seem to be in the tracker. :-( A crash is our bug and needs to be

Thanks for the code and the hints. I haven't tried it out yet, but I
see now that the error with magit is caused by calling invisible-p,
which doesn't seem to exist. (Maybe I should try emacs out with magit
to see if provides something over what I get with git.el now.)

Yeah, I did find some version of sdiff, but it seems the api that git
expects wasn't what sdiff provided. I didn't investigate further, but
I do intend to, since merge conflicts do happen to me once in a while.

I could not find any report so I created one now.
http://tracker.xemacs.org/XEmacs/its/issue853
As reported it is an assertion that fires. The comment above the
assertion is interesting:
/* #### This assertion must be true before the if statements are hit
but may possibly be wrong after the call to
point_in_line_start_cache if orig is outside of the visible
region of the buffer. Handle this. */
Maybe this can help in finding what is wrong.

Ok, I tried it out. (I didn't look for a file handler or did anything
about stderr handling).
With just one more change for a call to local-variable-p with just one
arg instead of two, magit will start up and appears to run. There are
some issues of course.

You can find them at https://github.com/rtoy/xemacs-hacks.
Grab git.el and emacs-simple.el for plain git.el support.
Grab ido.el and the magit directory for magit. Oh. I forgot to include

I have no objection to adding git.el to someplace appropriate (maybe a
new package vcs-tools or dvcs-tools?), but magit.el clearly needs
work, some on XEmacs syncing to GNU, some on syncing magit to XEmacs
reality.
You can put magit.el in a packages/contrib/matsl/magit package though,
making it available and cooperatively hackable to all (subject to your
permission since it's your namespace, of course -- maybe we should
create a protocol for that, such as simply creating common packages at
the packages/contrib/ leve).

Agreed. It should not be included blindly but fixed first so that it

I do assume that. What I wanted to point out is that there is an
intermediate step between your private file system and the official
XEmacs package repo -- the contrib repo.
Of course github or the hg equivalent is fine too.

I haven't seen the crash in a while, but that could be because of

sign, since I've been using git.el everyday since then without a

No, not yet. I don't get conflicts very often so I don't get a chance
to test. And when I do, I need to get the conflict fixed right away
so that I can continue do my work.
One enhancment that I would like to make is that git.el doesn't know
about tags in git. This is annoying when you do C-u C-x v = and then
you can't do tab completion when prompted for the old (and new)
version.

OK. So git.el has been updated? I will have a look. I don't remember
but it is out there somewhere I guess. I found it the last time ;-)
No, not yet. I don't get conflicts very often so I don't get
a chance
to test. And when I do, I need to get the conflict fixed right away
so that I can continue do my work.
I know, I know...
One enhancment that I would like to make is that git.el doesn't
know
about tags in git. This is annoying when you do C-u C-x v = and
then you can't do tab completion when prompted for the old (and new)
version.
Feel free to do that! It sounds useful. ;-)

It's here: https://github.com/rtoy/xemacs-hacks. I think you can grab
just git.el. smerge-mode.el was a start on getting smerge working,
but I haven't done anything with that yet.

OK. That explains it. I checked the git distribution and it wasn't
updated there. I'll test your version!
