gnus should backup .newsrc.eld

[jidanni]

Why doesn't gnus make a backup of its .newsrc.eld?
Don't ask me "Why, what could ever go wrong?"
Just save one old version by default.

Mine does.  I always have .newsrc.eld~ with the previous version.  I
don't see anything in my settings that suggests I've done something
special to have it.

If doing so, we'll also have to backup nnfolder-marks, nnml-marks,
and nntp-marks, that all are preferred to .newsrc.eld.

Oh, there it is
-rw-r--r-- 1 95765 2008-12-12 13:12 .newsrc.eld
-rw-r--r-- 1 95751 2008-12-12 12:06 .backups/.newsrc.eld!!!home!jidanni!~
I see, I am using
;;; backup-dir.el --- allow backup files to live in some other directory(s).
I found somewhere. Well, that's only one measly backup...

You don't need an external lib to do that.  That's what I use:

--8<---------------cut here---------------start------------->8---
(setq version-control t)

;; Save the 20 last versions!
(setq kept-old-versions 0)
(setq kept-new-versions 20)
(setq delete-old-versions t)
(setq backup-directory-alist
      '((".*" . "~/.backupFiles/")))
--8<---------------cut here---------------end--------------->8---

Ah... mine don't, because of this setting in .emacs:
(setq make-backup-files nil)

(The setting goes back to 1993-1995, and PC-NFS becoming very confused
when new versions of files got new inodes (ie. when I edited a file in
emacs on unix, programs on the PC still saw the old version).  I could
change this now, I guess... but I've never had much use for the ~
backups so losing them was actually losing a nuisance.  The autosave
files on the other hand, them I could not do without)

However, the .newsrc.eld also is the single repository for much
information that's mostly static:
 - Group parameters
 - Servers that are browsed to

That makes sense to back up (and IMO makes sense to move to a separate
file).

You can have it anyway.

(defun my-gnus-save-quick-newsrc-hook ()
  (set (make-local-variable 'make-backup-files) t)
  (set (make-local-variable 'version-control) t)
  (set (make-local-variable 'delete-old-versions) t)
  (set (make-local-variable 'kept-old-versions) 0)
  (set (make-local-variable 'kept-new-versions) 6))
(add-hook 'gnus-save-quick-newsrc-hook 'my-gnus-save-quick-newsrc-hook)

Oh, every body missed (info "(gnus)Startup Files") "If you want
version control for this file, set `gnus-backup-startup-file'."
Well, maybe it should be t by default.

Whether backups of ~/.newsrc.eld are created is controlled by
`make-backup-files'.  `gnus-backup-startup-file' just controls whether
Gnus makes numerical backups, like `version-control' does for other
Emacs files.  In other words, `gnus-backup-startup-file' overrides
`version-control' for .newsrc.eld, nothing more.

So with the defaults (make-backup-files == t, gnus-backup-startup-file
== never) you get a single backup file for .newsrc.eld (see the doc
string of `version-control').  One could argue that
`gnus-backup-startup-file' should default to the value of
`version-control', but as .newsrc.eld tends to become large, it might
be a good idea to create only a single backup.  But defaulting to t
(i.e., make numeric backup versions unconditionally) — independent
from the value of `version-control' — is a bad idea, IMHO.

For now, I fixed the doc string of `gnus-backup-startup-file' which
was misleading:

Didn't miss it exactly.  I've never looked, because I'm not so much
interested in having a backup version of this file (or any file).

However, I _am_ interested in moving the mostly static information
(group parameters, server and agent settings), residing in this file,
into a separate file that isn't as large, and isn't saved as often.

Re: gnus should backup .newsrc.eld

[jidanni]

(I now do (setq gnus-backup-startup-file version-control) in .gnus.el,
and (setq version-control t) in .emacs.)

And can be edited by humans [even if only when gnus is turned off.]
E.g., I can never use the "Customize" system (too dazzling), and edit
~/.emacs-custom.el by hand.
