In the group gmane.comp.security.risks on server nntp:news.gmane.io open
an article and type C-d (gnus-summary-enter-digest-group).
Then enter a message from the summary buffer (e.g., SPC)
and now (gnus-fetch-original-field "Newsgroups") returns nil instead of
"gmane.comp.security.risks" as it should.
The variable gnus-original-article-buffer evaluates to
" *Original Article gmane.comp.security.risks*"
and that buffer starts like this:

I think there's a misunderstanding here -- the "original" that the
function is fetching is the unformatted "original" version of the thing
that's displayed in the *Article* buffer. It has nothing to do with how
the article was sourced (which was via a digest in this case).
So this is working as designed.

If you want to get at the newsgroup name of the parent group, that's
stashed in the info params, so you should be able to get at that data
via something like:
(gnus-info-params (gnus-get-info gnus-newsgroup-name))

You have to call that in the nndoc group.

I don't think the latter is stored anywhere.

Context (see https://debbugs.gnu.org/cgi/bugreport.cgi?bug=54423):
`bbdb-message-header' calls `gnus-fetch-original-field' which,
for a digest ("nndoc") group, returns nil for every header.
The root of the problem is that `gnus-fetch-original-field' relies on
`gnus-original-article-buffer' which is buffer-local:
--8<---------------cut here---------------start------------->8---
gnus-original-article-buffer is a variable defined in ‘gnus.el’.
Its value is
" *Original Article nndoc:gmane.comp.security.risks-1023*"
Local in buffer *Summary nndoc:gmane.comp.security.risks-1023*; global value is the same.
--8<---------------cut here---------------end--------------->8---
(buffer " *Original Article nndoc:gmane.comp.security.risks-1023*" is _empty_!)
and at the _same_ time (no gnus command executed, just a buffer switch):
--8<---------------cut here---------------start------------->8---
gnus-original-article-buffer is a variable defined in ‘gnus.el’.
Its value is " *Original Article gmane.comp.security.risks*"
Local in buffer *Summary gmane.comp.security.risks*; global value is the same.
--8<---------------cut here---------------end--------------->8---
Lars suggested that I use this:
--8<---------------cut here---------------start------------->8---
(gnus-info-params (gnus-get-info gnus-newsgroup-name))
--8<---------------cut here---------------end--------------->8---
and it appears that the following works:
--8<---------------cut here---------------start------------->8---

`quit-config' contains the parent summary buffer object.
I would rather use that directly that construct the string
" *Original Article gmane.comp.security.risks*"
(especially since the relevant logic in `gnus-article-setup-buffer' is
moderately convoluted).
The question is whether this is TRT or there is a better way.
Thanks to Lars for his patience, and to everyone else for possible
suggestion.

...Is the (and-let*... needed? Of course, one could wrap all code that
way. But and-let* is not even part of Emacs 25 that current BBDB is
supposed to support. Also, if the above code should fail in certain
cases, it might be an indication that the above code is not yet exactly
what is needed so that this should not be swept under the carpet. So I
feel that
(with-current-buffer (cadr (assq 'quit-config
(gnus-info-params
(gnus-get-info gnus-newsgroup-name))))
is the better way to go. Am I missing something?
Or: If the corner cases when the code can still fail are known and the
failure is in that sense intentional, this should be made more explicit
in the code.

I added bbdb-user to CC.
For context (see https://debbugs.gnu.org/cgi/bugreport.cgi?bug=54423 for
full details), the problem is that `bbdb-message-header' calls
`gnus-fetch-original-field' which, for a digest group, returns nil.
This prevents `bbdb-accept-message-alist' from working for, e.g.,
--8<---------------cut here---------------start------------->8---
(("Newsgroups" . "\\(gmane\\.emacs\\|gmane\\.comp\\.security\\.risks\\)"))
--8<---------------cut here---------------end--------------->8---
because every message in gmane.comp.security.risks is a digest.

Okay, so how do I extract "Newsgroups" or "Content-Type" for a message
in a digest?
Thank you Lars.

While I included the call of `gnus-fetch-original-field' in
`bbdb-message-header', I need to admit that the above issue goes much
beyond my knowledge of Gnus internals. If there are better ways for
`bbdb-message-header' to achieve what it needs to achieve (which is
grabbing the content of (what appear to be) headers of a message),
then I certainly appreciate any patches for BBDB.

If the intention is to collect data from the parent group (which is a
thing mostly just for nndoc groups), you first have to determine what
the parent group is, and then you can select the data from the buffer
that's named something like " *Original Article group.name*".

Thanks for the clarification! - This brings me back to what I said: if
someone more knowledgable of Gnus internals can translate the above into
code for `bbdb-message-header', I'll appreciate that. I can also try do
that myself. But then I cannot promise anything.

...which brings us back to my original message ;-)
Specifically, `bbdb-message-header' calls
--8<---------------cut here---------------start------------->8---
(defun gnus-fetch-original-field (field)
"Fetch FIELD from the original version of the current article."
(with-current-buffer gnus-original-article-buffer
(gnus-fetch-field field)))
--8<---------------cut here---------------end--------------->8---
The variable gnus-original-article-buffer evaluates to
" *Original Article gmane.comp.security.risks*"
and that buffer starts like this:
--8<---------------cut here---------------start------------->8---
Path: news.gmane.io!.POSTED.blaine.gmane.org!not-for-mail
From: RISKS List Owner <risko@csl.sri.com>
Newsgroups: gmane.comp.security.risks
Subject: Risks Digest 33.09

To: risks-resend@csl.sri.com
...
--8<---------------cut here---------------end--------------->8---
and (gnus-fetch-original-field "Newsgroups") returns nil even though the
original article buffer contains the appropriate header...
Thank you for your kind attention.

Nevertheless, the '''unformatted "original" version of the thing
that's displayed in the *Article* buffer''' is the
`gnus-original-article-buffer' which points to buffer
" *Original Article gmane.comp.security.risks*"
which _does_ contain all the needed goodies,
_BUT_ `gnus-fetch-original-field' does _NOT_ return them.
IOW, `mail-fetch-field',
called by `message-fetch-field',
called by `gnus-fetch-field',
called by `gnus-fetch-original-field',
returns nil.
`gnus-fetch-original-field' calls `gnus-fetch-field'
inside `with-current-buffer gnus-original-article-buffer`
and the buffer referenced by `gnus-original-article-buffer'
_does_ contain the fields in the header.
> So this is working as designed.
Then how should bbdb extract the "Newsgroups" et al?
Thank you!
