This bug report will be sent to the Bug-GNU-Emacs mailing list
and the GNU bug tracker at debbugs.gnu.org. Please check that
the From: line contains a valid email address. After a delay of up
to one day, you should receive an acknowledgement at that address.
Please write in English if possible, as the Emacs maintainers
usually do not have translators for other languages.
Please describe exactly what actions triggered the bug, and
the precise symptoms of the bug. If you can, give a recipe
starting from `emacs -Q':
I've tried to install Emacs 24.2 from multiple sources:
http://emacsformacosx, the GNU sources (configure --with-ns), and
MacPorts. All of them have the same problem on *two* different Macintosh
computers running Mountain Lion. Emacs 23.4 works just fine. BTW, I've
been using emacs for about 20 years, so the bug (saving a file to disk)
isn't pilot error.
When I start emacs and create a new file (~/abc) and type
something into it, the two asterisks appear to show that the buffer is
modified. When I attempt to save it, I get the message "Saving file
/Users/jcroix/abc...". However, the message never goes away, the two
asterisks never disappear, and the file is never written.
If I look at my directory, I can see the restore file ".#abc ->
jcroix@mac-jcroix.cadence.com.24380" with a size of 35, but the file
"abc" is not present.
When I attempt to quit emacs (^x ^c), I get the message "Save file
/Users/jcroix/abc? (y, n, !, ., q, C-r, d or C-h)" at which point I hit
"y". Up pops a message "Modified buffers exist; exit anyway? (yes or
no)". If I type "no", I remain in edit mode, and the two asterisks are
still present. If I type "yes", the save file is deleted but the file
"abc" is absent.
There are no errors in the "*Messages*" buffer. Here are the contents
of that buffer:
Loading delsel...done
Loading paren...done
For information about GNU Emacs and the GNU system, type C-h C-a.
(New file)
Saving file /Users/jcroix/abc...
So it's trying to save it -- it just doesn't manage to do so.
If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
`bt full' and `xbacktrace'.
For information about debugging Emacs, please read the file
/opt/local/share/emacs/24.2/etc/DEBUG.

Hello.
I can't reproduce this. Are you sure you started with -Q?

Oops. I missed that part of the bug report instruction set. Running with "-Q" works. Running without "-Q" doesn't.
I can generate a QuickTime video to show the problem if you like.

John

Ok, so something in your .emacs is causing this.
Try bisecting it. Remove half of your .emacs and try again. If it works, put back the other half, and remove half of that. If it doesn't work, remove half again, and so on.
Hopefully you can pinpoint what package or lisp statement that causes this.
You can also start Emacs normally and see what the value for before-save-hook is (C-h v before-save-hook). If it is non-nil, that is a prime suspect. Try setting it to nil and see if it works.

Well, now I feel like a complete fool. I never even thought of the .emacs file. I've been using the same one for so long that I don't even think about it anymore. It probably would have helped had I read the bit about starting emacs with the "-Q" flag.
I tracked the problem down to the following (in red):
(setq-default indent-tabs-mode nil)
(add-hook 'write-file-hooks
(lambda ()
(if (not indent-tabs-mode)
(untabify (point-min) (point-max))
(delete-trailing-whitespace))))
When I comment out that line, everything works. When the line is present, it doesn't work.
Since most of the files that I work on are C++ source files, I want to untabify the buffer and delete any trailing white space. Obviously, though, this doesn't work on make files. I picked up this little piece of code from an emacs wizard friend and have never revisited it.
So, is this a bug or is the untabify command no longer supported? If it's now a bug, this should now be reproducible. If it's an obsolete package, do you have any suggestions for a replacement?
Thanks for walking me through this.
Regards,
John

Which line?
Have you tried reading the documentation of write-file-hooks?
List of functions to be called before writing out a buffer to a file.
If one of them returns non-nil, the file is considered already written
and the rest are not called.
Andreas.

Properly indented, the `add-hook' form above here appears as
(add-hook 'write-file-hooks
(lambda ()
(if (not indent-tabs-mode)
(untabify (point-min) (point-max))
(delete-trailing-whitespace))))
so if `indent-tabs-mode' is on, you delete trailing whitespace and if
it's off, you untabify. Is this what you really want?
Anyway, the problem seems that `untabify' returns non-nil and according
to the doc-string of `write-file-hooks' we know that this is a
List of functions to be called before writing out a buffer to a file.
If one of them returns non-nil, the file is considered already written
and the rest are not called.
which is slightly ambiguous: One might think that if one of them returns
non-nil Emacs will "not call the rest" but nevertheless save the buffer
to its file.
In your case writing the file is aborted because `untabify' returns the
"current column `move-to-column' moved to" (whatever that is it seems to
be non-nil). So maybe we should modify the return value of `untabify'
(like in `delete-trailing-whitespace') or you should use
(add-hook 'write-file-hooks
(lambda ()
(if (not indent-tabs-mode)
(progn
(untabify (point-min) (point-max))
nil)
(delete-trailing-whitespace))))
still modulo your real intentions of what that lambda is supposed to do.

Or just use whitespace-mode.

Indeed. Maybe we should improve the Emacs manual to tell more
about its capabilities.

Thanks for all the help and suggestions. Here's what I can tell you:
I've never programmed in LISP, so I picked this piece of code up from a friend who is. That's not an excuse for not trying to figure it out on my own. However, I hope that explains why I'll say that I have no idea what the lambda function does in LISP. I'm familiar with C++11's new lambda features, but the semantics of LISP... no clue. Looks like I'll need to become familiar with LISP.
The intent of the code was to do 2 things
Always delete trailing white space from any file
Untabify files for which indent-tabs-mode is nil. From what I understand, this variable is set to a non-nil value for makefile mode but isn't necessarily set for other modes. Thus, the prior statement sets indent-tabs-mode to nil for all modes that don't normally set it.
While it now looks like the code doesn't actually do the two things that I wanted it to do, it never stopped the process of writing files before. I'm using the same initialization file for emacs 23.4. It seems to me that this means that (1) untabify didn't return a result before or (2) the write operation didn't depend on a nil value return in order to write. So is this a bug in 23.4 that's fixed in 24.x? A feature change in 24.x for untabify or the write operation?
Again, thanks for the helpful feedback. Sorry to submit a bug report on a user error.
Regards,
John

A quick follow up. Thanks to your input, I've rewritten the code, and it seems to do everything that I need it to do in 24.2.
(add-hook 'write-file-hooks
(lambda ()
(delete-trailing-whitespace)
(if (not indent-tabs-mode)
(untabify (point-min) (point-max)))
nil))
Thanks again,
John

BTW, try C-h v write-file-hooks: you'll see it's been obsolete for
a while.
