Did this start happening yesterday?  Then this might be related to this

Thanks for the pointer.  It didn't start happening yesterday, but I
thought I also saw it with a fresh build, but maybe I was imaging things.

Maybe mailcap-mime-data should have an implicit USER-SET/PRIORITY flag
that is added to entries read from user-mailcaps.  These could then be
preferred by `mailcap-viewer-lessp'.  Would that solution work?

IMO it's extremely annoying.  Doc-view is nice and all, but it's not fast
enough for being the default viewer (initial load is 5s of seconds
sampling typical pdfs from the last couple of days, zoom and scrolling is
very slow).

For now I'll eradicate doc-view from mailcap-mime-data manually.

I though the first viable viewer in the list would be used?  So the
priority is how it's ordered...

I took his word for it, though.

On my system:
(assoc "pdf" (assoc "application" mailcap-mime-data)) =>
       ("pdf" (viewer . "evince %s") (type . "application/pdf")) 

But I'm still stuck with doc-view...

Oh, sorry, forgot that bit...

I've looked at the code a bit more, and what it's doing now seems rather
odd.

I can't seem to get

(mailcap-mime-info "application/pdf")

to respect my ~/.mailcap file at all?  Is that a bug or is it supposed
to be that way?

OK.  I haven't checked it yet.

Nope.

I picks up evince, which is in my ~/.mailcap after I remove doc-view-mode:

(setcdr
   (assoc "application" mailcap-mime-data)
   (remove '("pdf"
             (viewer . doc-view-mode)
             (type . "application/pdf")
             (test eq window-system 'x))
           (cdr (assoc "application" mailcap-mime-data))))

A bug, I hope!

Thanks,
Rasmus

No, that's the problem: the viewer is picked by ordering them using
`mailcap-viewer-lessp`, and that function is giving preference to
elisp-based viewer over any other, no matter in which order they were
read.  IMHO, that's a bug.

Recent Emacs doesn't respect my mailcap

[Rasmus]

Hi,

In recent Emacs (v25+) doc-view has completely taken opening PDFs from
within Emacs, disregarding my preferences as stated via ~/.mailcap.

Before, mime types of 'application/pdf' would be opened via evince in both
org and gnus.  Now if I'm lucky it opens in doc-view or, worse, (in gnus)
asks me where to save it.

From emacs -q, doc-view respects neither of these settings:

(require 'mailcap)
;; neither of these works
(mailcap-add  "application/pdf" "evince %s")
(mailcap-parse-mailcaps)
;;  ~/.mailcap has the line:
;; application/pdf; 		evince %s;
;; application/*; 	        xdg-open %s;


I looked through etc/NEWS but didn't see any obvious source of this new
behavior.  

Can anybody tell me what might've cause doc-view's recent power-trip? 

Thanks,
Rasmus

Thanks for bringing this up ! I have similar problems. I think
7747e23ecd6c7b140a67812ad22421ef426a7a24 is a potential culprit.
