With this patch, what happens if someone is emailing using an old
version of Emacs? Does that matter, or is this stuff based only on the
file ending?
Org files are plain text files and have no specific signature that would
allow tools like libmagic to unambiguously distinguish them from other
text files. Rare files have explicit "# -*- mode: org-mode -*-" header.
So there is no other way besides file name extensions when a message is
composed or a file is served by a HTTP server. Clients should rely on
the Content-Type header.
Old mailers will continue sending messages with
application/vnd.lotus-organizer, text/x-org, or text/org media type.
IOW, I'm asking if it is backwards-compatible to remove
"text/org", in either direction.
I suggest to use text/org instead of text/x-org.
Will .org files be displayed in the
same way as before or not on both new and old versions?
I do not see a better way toward consistency in respect to the media type.
I've noticed on my machine that .org files have been interpreted as
application/vnd.lotus-organizer.
From my point of view, it is a reason to not bother concerning removing
of "text/x-org" from `mailcap-mime-extensions'
Presumably that's due to some local
configuration in /etc/mime.types on my distro. Is that correct?
There are 2 projects maintaining /etc/mime.types, they follows IANA
registry, so have application/vnd.lotus-organizer. XDG shared-mime-info
project (another media types DB, not /etc/mime.types) has text/org.
Is it
documented somewhere how to override that system configuration in Emacs?
Create ~/.mime.types. Debian's variant suggests it in the
/etc/mime.types header.
But thinking about this more, why not do that unconditionally for users?
Lotus Organizer is dead, long gone, and not really relevant to anyone,
certainly not to the overwhelming majority of Emacs users.
Ideally text/org should be registered in IANA, so all applications could
use consistent mapping. Prerequisites have been discussed already.
