Hi
The following kills me.
I have set
make-backup-files t,
vc-make-backup-files nil
I am in a directory which is under version control (mercurial).
The file test.org and test.tex are *both* under VC control.
However when I export test.org to test.tex say twice
the files
test.tex
and
test.tex.~1~
are generated and if I export once again I will have another backup
file.
I even set in my orgfile
#+BEGIN_SRC emacs-lisp
(set (make-local-variable 'make-backup-files) nil)
#+END_SRC
But it does not help
Is this a bug?
Regards
Uwe Brauer

but this will not affect the setting of that variable for the .tex file,
only the current org file where you execute this lisp code, which is why
you get the backup copy being made.

But the .tex file is under VC control, so no backup copy should be made,
since
vc-make-backup-files nil
(but that may only apply I make in the file)
Do you have any idea how to avoid the creation of the backup files,
without setting the make-backup-files variable globally to nil.

I can only suggest that you might be able to make that variable local to
the .tex file using some hook? I have no idea which hook or whether
such is possible, mind you.

FWIW, I tried a set-up with git (I don't have mercurial available) and I cannot
reproduce this.
I'm not using numbered backups but the two variables you mention are set the
same way for me. Here's what I did:
- created a directory "foo" and cd'ed to it.
- `git init'
- create "test.org" and export to create "test.tex".
- `git add test.org test.tex'
- `git status' to check that everything looks good.
- modify test.org and export a few times.
- at every export, do `ls -la'. I always get this:
,----
| $ ls -la
| total 12
| drwxrwxr-x. 4 nick nick 62 Jun 21 13:04 .
| drwxrwxr-x. 14 nick nick 4096 Jun 21 13:03 ..
| drwxrwxr-x. 2 nick nick 21 Jun 21 13:04 auto
| drwxrwxr-x. 7 nick nick 132 Jun 21 13:04 .git
| -rw-rw-r--. 1 nick nick 67 Jun 21 13:04 test.org
| -rw-rw-r--. 1 nick nick 788 Jun 21 13:04 test.tex
`----
with no trace of backups.
Maybe try with git and see if you can reproduce the problem?
If not, I'd suspect either that the tex file is not under VC
or there is some incompatibility between mercurial and the
emacs vc package.
Also, there are two ways to make a backup (renaming and copying -
I use copying) and maybe the method you use is incompatible with
mercurial. Maybe you can try the other method: check the setting
of `make-backup-by-copying'.

A wait what do you mean you have not set up numbered backups, maybe this already is
the difference. I will come back to the point later

Which is the expected behavior.
> Maybe try with git and see if you can reproduce the problem?
I did and yes the problem also occurs in git, so the
problem is my setting not git/mercurial, which is good.

I have a relatively recent version of GNU emacs master, but cannot find
the variables make-backup-by-copying. Could you please explain.
I had however
backup-by-copying set nil, now it is t, but still the behavior is the
same.
So maybe it boils down to what you said at the beginning
> I'm not using numbered backups
https://www.gnu.org/software/emacs/manual/html_node/elisp/Numbered-Backups.html
Ok I had
Version-control set to t.
I changed it to nil: no change
I changed it to never: emacs now makes test.tex~ instead of test.tex.~1~
I am running out of ideas.
Where is the mistake?

Do you have really
make-backup-files t,
vc-make-backup-files nil
The only way I can stop the backup nightmare, is set it to nil,
globally, which is not what I want.

Finally
(setq backup-directory-alist '(("" . "~/.emacs.d/backup")))
Sort of solves my problem. (What I cannot see does not exist)

Those are the setting I have.

Why not? If it's under VC, why do you need emacs to make backups for you?

But only some of my files are, most of them are not under VC, so if I
set this variable globally to nil, no backups for files which are not
under VC control
