gnome-tweak-tool tweaks

Hi,

When starting gnome-tweak-tool, it prints a warning

    GLib-GIO-Message: Using the 'memory' GSettings backend.  Your settings will not be saved or shared with other applications.

The patch below has gnome-tweak-tool communicate with gsettings instead
of using the `memory.  I'm not sending it as a fix yet because 
gnome-tweak-tool does not list any themes, as davexunit reported.

I'm attaching the log that I get when building it, there's a warning
about xml files not being written and collisions, could that be the
cause of missing themes?

Greetings, Jan

So does the patch fix something?  (Sorry, I’m quite ignorant about
GNOMEy things.)

> I/O error : Permission denied

I found that string comes from ‘shared-mime-info’, which is itself used
by the ‘xdg-mime-database’ hook in (guix profiles) (a hook that runs
when the profile is created to update the MIME database):

--8<---------------cut here---------------start------------->8---
static gboolean save_xml_file(xmlDocPtr doc, const gchar *filename, GError **error)
{
#if LIBXML_VERSION > 20400
	if (xmlSaveFormatFileEnc(filename, doc, "utf-8", 1) < 0)
	{
		g_set_error(error, G_FILE_ERROR, G_FILE_ERROR_FAILED,
			    "Failed to write XML file; For permission problems, try rerunning as root");
		return FALSE;
	}
#else
--8<---------------cut here---------------end--------------->8---

宋文武: any idea what the problem might be?  Perhaps
‘update-mime-database’ is trying to write to /gnu/store/…-something?

Also, it’s a problem that ‘update-mime-database’ returns 0 here, as
seems to be the case.

Thanks,
Ludo’.

Yep, it happends when '$out/share/mime/application' is not writable.
The xml files under 'application' are going to be generated by
update-mime-database, and the shared-mime-info package has it
pre-generated, so after union "share/mime", an un-writable 'application'
directory point to the store will cause the problem.

Commit 359f06aa fix this by union the "share/mime/packages" directory.

It returns 256 here for the problem, but the derivation still built and
profile got updated, I have no idea about this :-

Does a failing hook (returns #f) supposed to top the profile update?

That depends on how you look at it.  It takes away the cause of the
warning message, so now settings are sent to gnome-settings instead
of kept in-memory.  However, I'm still not sure that gnome-settings
saves its settings, which should happen upon logout which we do not
have yet.

So one chain in the link is fixed, but I think there is still another
link that is broken.

Greetings,
Jan

OK, thanks for the quick (brown?) fix!

I thought it did, but it doesn’t:

  (gexp->derivation "foo" #~(begin (mkdir #$output) #f))

leads a derivation that succeeds, contrary to
‘build-expression->derivation’.

To avoid that, we need an explicit (exit #f).

For now I prefer to address it at every call site (patch below) instead
of adding some magic to ‘gexp->derivation’, which would be hard to do in
a hygienic way.

Thanks,
Ludo’.

To put it differently: do we need to apply it, or does it just serve as
an illustration for the discussion?  :-)

It's okay to apply it, but I suspect more coming.  I think/hope
davexunit found something wrt XDG_DATA_DIRS and theming, kori reported
libsoup and gnome-desktop were needed, which I also don't know what to
do with yet.
