Gnus 5.6.38 and Emacs 20.3

Gnus 5.6.38 and Emacs 20.3

[Bill White]

Gnus v5.6.38, GNU Emacs 20.3.1 (i586-unicent-linux-gnu, X toolkit) of
Thu Aug 20 1998 on banshee

gnus-group-suspend works fine so far with 20.3.1, but C-c C-c (aka M-x
message-send-and-exit) returns the following message in the minibuffer
and doesn't sent the message:

----------------------------------------
Attempt to set a constant symbol: :-pos
----------------------------------------

Is there something more I could report to help debug things?

Thanks  -

Bill

`(setq debug-on-error t)', repeat the bug and mail me the resulting
backtrace.

I haven't seen this problem (yet, this is my second message using
20.3/5.6.38 :), but on the subject of Emacs 20.3: I had to add this
snippet to my .emacs in order for Gnus not to misunderstand the names
of my 8-bit-character-containing-mail-group-names:

;; And I don't want my .newsrc.eld MULEified, as this messes up mail
;; group names with 8-bit characters:
(setq file-coding-system-alist
      (nconc '(("\\.newsrc\\.eld\\'" no-conversion . no-conversion))
	     file-coding-system-alist))

Could Gnus maybe include somthing like that, or bind
`coding-system-for-read' appropriately before it reads our
"~/.newsrc.eld"s?

I have this in my ~/.gnus:

;; I'm using ÅÄÖ in my .newsrc.eld
(setq gnus-startup-file-coding-system 'iso-8859-1)

/s

That doesn't work here -- it converts all instances of e.g. the single
iso-8859-1 character "Å" into the four characters "\305".  It might
work if you had this set up when you created your first
8-bit-character-containing-group-name, but that's not what I want.

Gnus binds `coding-system-for-read' before reading the file(s) with
the value of `gnus-startup-file-coding-system'.  Which is `binary' by
default.  Should it be `no-conversion' instead?

`binary' should be correct.  `no-conversion' can change LFs to CR-LFs
and vice-versa.

Let me see if I have this straight: `no-conversion' does a conversion?

Yup.  Splendid, isn't it?  Call it "hysterical reasons"!  :-(

Partially incorrect.  no-conversion doesn't change line endings.
binary is an alias for no-conversion.

Not so under XEmacs.  I don't guarantee for FSF Emacs/MULE.

Great.  Dunno how I got to believe my snippet was needed at all, as it
doesn't appear to be needed now.

Grrr!  I'm sure I've seen this problem before, a while ago in fact, and
I remember that the mere solution was to rename a few variables all over
some Emacs LISP source.  The sad thing is that I do not remember which,
nor why.  It was something like changing `...:-pos' to `...:-position',
maybe.  I likely reported the problem, whatever it was.  The trick Lars
gave you, that is "(setq debug-on-error t)", should help you identifying
where the problem occurred, at least.

Lars came up with the right answer. I had just upgraded to Emacs 20.3
(my first emacs upgrade) and just copied all the .el and .elc files
from 20.2's site-lisp dir to 20.3's. All I had to do was delete the
.elc files & byte-compile with 20.3. Problem solved!

No, it's `:-pos' to `colon-pos'.  The file in question is
`mail/mail-extr.el', and the problem occurs because Emacs 20 supports
unquoted keywords, and signals an error if you try to assign a
different value to them.
