bug#26558: Opening URLs with xdg-open fails (eg. Gajim, Pumpa)

bug#26558: Opening URLs with xdg-open fails (eg. Gajim, Pumpa)

[Ben Sturmfels]

Hi Folks,

When I click an embedded URL within Gajim or Pumpa, I'm expecting a
browser window to pop up, but nothing happens and I get an error on the
command line:

  /home/ben/.guix-profile/bin/xdg-open: line 341: gnome-open: command
  not found

The same error shows up if you attempt try the URL with xdg-open
directly:

  $ xdg-open https://www.gnu.org/software/guix/
  /home/ben/.guix-profile/bin/xdg-open: line 341: gnome-open: command not
  found

As this message suggests, "gnome-open" is hard-coded into the "xdg-open"
script on line 341.

In Trisquel 7 and Debian Unstable the "gnome-open" executable is
included in the "libgnome2-bin" package, which I gather is deprecated.
Some quick searching around suggests that "gvfs-open" might be the the
appropriate replacement for "gnome-open":

  https://askubuntu.com/questions/101965/what-is-the-replacement-for-gnome-open-in-gnome
  https://wiki.gnome.org/Initiatives/GnomeGoals/RemoveGnomeOpenGnomeHelp?highlight=%28gnome-open%29
  https://wiki.gnome.org/Attic/LibgnomeMustDie?highlight=%28gnome-open%29

I assume that means either:

  a. packaging the deprecated gnome-open,
  b. modifying xdg-open to use gvfs-open instead of gnome-open, or
  c. in Gajim's case, possibly using "gtk_show_uri"?

Cheers,
Ben

I don't think so because this is what I get when running xdg-open:

    # this does not work:
    $ xdg-open http://gnu.org
    /home/mekeor/.guix-profile/bin/xdg-open: line 369: firefox: command not found
    /home/mekeor/.guix-profile/bin/xdg-open: line 369: mozilla: command not found
    /home/mekeor/.guix-profile/bin/xdg-open: line 369: netscape: command not found
    xdg-open: no method available for opening 'http://gnu.org'

    # this works just fine:
    $ BROWSER="icecat" xdg-open http://gnu.org

As you might have guessed, I do not use GNOME.

Did you try to set BROWSER environment variable?

bug#26558: Opening URLs with xdg-open fails (eg. Gajim, Pumpa)

[Arun Isaac]

Thank you for the bug reports!

The Guix xdg-utils package is in need of an update. The latest release
is 1.1.1. Unlike the 1.0.2 release currently in Guix, the new release
has test cases, many of which currently fail in Guix. While trying to
get the tests to pass, I noticed that /usr/bin/file is hardcoded into
xdg-mime. That, I think, is at least part of the problem. I am working
on this, and will hopefully be done this weekend. We will revisit these
bugs after that.

Heh, I've had a WIP update for 1.1.1 for some time and decided to finish
it based on this discussion. This tries "gvfs-open" before "gnome-open".

@Ben (and others), can you try this patch and see if that works for you?

Have you tried setting the XML_CATALOG_FILES variable? You might be able
to get rid of the substitutions by using it. You can simply add libxml2
as an input, which will define such variable for you (thanks to Ludovic
for pointing this out previously!).

I tried now to add libxml2, and also set XML_CATALOG_FILES manually (and
both :)), but no luck. Thanks for the tip, though. Would be good to find
out why it doesn't work for this case.

Oh, good! :-)

Your patch builds successfully. But, the new version has tests, and you
still need to package them. When I try to run the tests, a few
fail. Setting environment variables HOME and BROWSER makes some tests
pass. This is about as far as I got with my WIP patch.

I had a go at this, and after adding some inputs and setting HOME only
four tests fail. Getting those to work in the build environment seems
pretty involved however (currently I'm starting xorg and adding a
"mimeapps.list"), so I shunted on this for now as it obscures the
update diff somewhat and is better suited as a separate patch.

IMO it's better to have a working package without tests, than a broken
package without tests ;-) Would be good to get it fixed though, will
give it a go at a later opportunity.

Ben: Can you confirm whether the latest xdg-utils work for you? It's in
'master' now so you should get it after a `guix pull` and update.

Yay, thanks for confirming! Closing this bug. :-)
