As a comparison point, when I use xdg-open or gnome-open, the Gnome PDF
viewer is launched. When I use see, xpdf is launched (okular not installed).

The freedesktop MIME system (which applies for GNOME, Xfce and LXDE)
allows to specify defaults for every given MIME type. However, it is
not realistic to agree in Debian as a whole on a set of defaults.

This is why GNOME sets default associations for GNOME sessions: this is
the /etc/gnome/defaults.list file. Therefore the behavior you describe
should not happen in a GNOME session – unless you start it through a
custom .xsession.

That’s for GNOME.


For other environments using the freedesktop MIME system, they can do
the same as we do for GNOME, but their respective maintainers have
decided not to. However, there’s been an addition to the MIME system
that allows to envision a Debian-wide solution: now you can specify
several defaults, and the system will pick the first one available.

So *if* we manage to agree on a list of defaults and on an order in
which they should appear, for each affected MIME type, we could ship
this file system-wide in shared-mime-info.

Note that the GNOME file alone lists no less than 355 MIME types, so
that makes quite some work.


For KDE I’ve been told the MIME system is different so this is yet
another story.

see is obsolete. Maybe the target for the next release could be to get
rid of it.

It is ridiculous that it is in fact completely arbitrary what
program is used to open files. Currently in my gnome-shell
pdfs are opened with a file-manager, as well as .txt files, as
well as anything.

That is when using xdg-open or gnome-open of gvfs-open.
When I try see, in contrast the funny okular from KDE
is started, together with these very useful services of KDE.

So maybe someone can explain what are the problems, that these
things are simply not fixd. Cannot be so complicated, right?



I think the most viable solution would be to:

1. Rewrite xdg-utils so that it is robust and always works. Instead of
relying on desktop environments, it should do the needed work by itself.
Currently it's something of a hack, especially when running in "generic"
mode. It should probably be written in another language than shell (e.g.
Perl, Python, C). A nicer user interface for the command line wouldn't
hurt either.


2. Make all other packages either use xdg-utils or follow the
freedesktop.org MIME specs.


I'm not planning on doing it myself though.

It you want to make xdg-open useable for everything, please also
add a way to specify the mime type as option. Without that using
it for opening mail attachements or stuff downloaded (i.e. things
that already show a mime type before you open it) is simply
introducing a security bug.

It appears that this has been done already, at least kfmclient accepts
mimetype as an option. However, for such sensitive use cases, I'd rather skip
the yet another level of indirection of having to second-guess an "opener"
app, being it xdg-open, kfmclient or any other, by mimetype hints, and just
inspect/dissect/open the suspicious thing as I find it most appropriate
depending on the circumstances (available inspection apps, time, etc)

It is much better to let xdg-open or what it launches determine the MIME
type by inspecting the contents of the file instead of reading the MIME
type from an email, anyway.

For browsers, there is a list of safe/unsafe MIME types, so inspection
is not required, but I’m not aware of a similar mechanism for email
readers.

This is already what e.g. gvfs-open does: the MIME type is determined
through content inspection according to the fd.o MIME specification.

pdfs are opened with gimp for me.

Hi,

Please consider making this a release goal when we call for them after
the release.

Thanks,
