Hm I am using gnus.
For example your message which I read via gmane in the newsgroup
gmane.emacs.orgmode

I hit enter or space, which I always do in order to read message via
gnus and again the minibuffer poped up with this question. I searched my
elpa archive and the only place where such a question is asked is in

(defun org-store-link

Now I don't understand why this function is called nor do I understand
why this question is asked without having set any variable.
Hm I have to search my init files,

Ok found it

(add-hook 'gnus-select-article-hook 'my-org-store-link-simple)


(defun my-org-store-link-simple ()
  "Translate TeX commands to png generated by org-preview-latex-fragment
into overlays or extents." 
  (interactive)
    (call-interactively 'org-store-link))

But the funny part is: if I call org-store-link
directly, *no* question is asked about mairix,

So what do I have to do to get rid of the question, could 
org-gnus-prefer-web-links be the culprit?
org-gnus-prefer-web-links is a variable defined in ‘org-gnus.el’.
Its value is t


Hm I debugged org-store-link, which was a considerable ordeal, and it
seems it is this

org-store-link-functions is a variable defined in ‘org.el’.
Its value is


(org-mairix-store-gnus-link org-rmail-store-link org-mhe-store-link
org-irc-store-link org-info-store-link org-gnus-store-link
org-docview-store-link org-bibtex-store-link org-bbdb-store-link
org-w3m-store-link)

And org-store link takes the first entry. I prefer him to take
org-gnus-store-link instead, how can I do this??

I have the feeling that this is relatively new (say from 2016).

What version of org are you using? In 9.0.5, I don't have a variable
called 'org-store-link-functions', but I have a function called that.
Is it possible that you have a mixed install?

As I said to Eric A., yes I had a terrible mix of old org installations
in my elpa directory. I deleted them all and started with a fresh 9.0.5
version and everything seems fine, now.

You are probably either loading explicitly org-mairix (from contrib)
or requiring 'org-mairix (explicitly or implicitly).

Try

   emacs -q -l /path/to/minimal.el

and evaluate

  (org-store-link-functions)

The returned list should not contain org-mairix-store-gnus-link.

Then

  (load-file "/path/to/org-mode/contrib/lisp/org-mairix.el")

and evaluate

  (org-store-link-functions)

The returned list will now contain org-mairix-store-gnus-link.

If you cannot find the place where org-mairix gets loaded (e.g with
find and grep), by using this method, you could bisect through your
init files to find it.

I don't know why you are seeing it now, but I don't think anything
has changed in the mairix space for years.

That is my feeling too, but I greped org-mairix in all my lisp files,
and found nothing.

I am not sure what minimal.el is supposed to be, but
emacs -q I might try.

Yeah I was hoping to avoid this, but maybe I have to do it sigh.

It may be a no-op or it may be a few lines of code, depending on how
you get your org-mode. For me, building from latest master every so
often, it's basically this:

--8<---------------cut here---------------start------------->8---
(add-to-list 'load-path "~/src/emacs/org/org-mode/lisp")

(require 'org-loaddefs)
;; not sure why I require org separately, but I guess I needed it
;; at some point - I should try without it.
(require 'org)

(add-to-list 'auto-mode-alist '("\\.org\\'" . org-mode))

(global-set-key "\C-cl" 'org-store-link)
(global-set-key "\C-cc" 'org-capture)
(global-set-key "\C-ca" 'org-agenda)
--8<---------------cut here---------------end--------------->8---

I believe this was merged indeed and it may be that org-mairix.el was not updated
to follow the new convention: that may be the cause of the problem, but avoiding
the load of org-mairix should resolve it in any case.

I think I found the culprit, I started emacs -q and the 
variable org-store-link-functions did not contain
org-mairix-store-gnus-link.

However when I loaded gnorb, org-store-link-functions 
*did* contain org-mairix-store-gnus-link.

@Eric what do you say?

I briefly scanned the code but cannot find why 
org-mairix-store-gnus-link is put into the list

Probably you've set `gnorb-gnus-mail-search-backend' to 'mairix. Then,
when you call `gnorb-bbdb-mail-search', that would result in a call to
`mairix-search', which I'm sure is autoloaded and will bring in the
whole package.

There's not much to be done about that: you can set
`gnorb-gnus-mail-search-backend' to nil (or a different backend) and
that will solve the problem, but if you ever try to use mairix, the same
thing will happen again.

No it is set to nil.

It seems that part of the problem was caused that is still sticked with
org-mode 8.3.X I have deleted that version and installed 9.0.5 and at
the moment everything looks fine. I hope also the registry problem I
reported to you privately is solved. But I will know for sure in a
couple of days.

In my org, which is reasonably up to date, there is no such
variable.  There *is* a function by that name, however.

What version of org are you using?

Following this up, in org v8, this was a variable but in org v9 it is
now a function.

Right, but I am still using
org-version is a variable defined in ‘org.el’.
Its value is "8.3.6"


So that setting should work, but maybe gnorb thinks that it is a
functions and this is where the trouble comes from.


Do you recommend to upgrade?
