fix: fallback implementation is used if preferred value of none #1255

SoumyaRanjanPatnaik · 2023-12-31T14:24:03Z

Don't use fallback portal implementations in the following cases:

the preferred portals for an interface contains none
no preference is set for the interface but the default preference contains none

Fixes #1254

Looks good to me.

Fixed lint issues :)

GreyXor · 2024-01-11T15:49:43Z

Hi, thanks for this PR. that would be nice to have this fix in the next release. That could fix sway+firefox idle inhibit https://gitlab.archlinux.org/archlinux/packaging/packages/sway/-/issues/2

jp7677 · 2024-02-09T07:33:36Z

Any chance to get this PR merged?
(That said, tests are failing, may be some additional work on that front is needed.)

This would fix the firefox-idle-inhibit issue not only for sway, but for other/all wlroots based compositors, labwc in my case.

GeorgesStavracas · 2024-02-09T10:55:09Z

Not only tests must pass, but the commits have to be squashed, and the commit message must follow the pattern that other commits do.

SoumyaRanjanPatnaik · 2024-02-09T11:00:03Z

@GeorgesStavracas The tests don't fail on my system. I can't figure out why they fail in CI.

You don't hit those errors locally because your test setup skipped those tests. From your logs:

19/24 xdg-desktop-portal:portals / limited-portals-openfile          SKIP            1.05s

SoumyaRanjanPatnaik · 2024-02-09T21:50:45Z

I don't want to be that guy, but either failing tests are wrong. Either that or the FileChooser interface has a bug. Let me elaborate...

Previously, with none not working, the limited-portals-openfile and limited-portals-savefile tests probably called an interface that is not enabled in the limited-portals.conf file.
This patch caused none to function correctly, which caused the calls to the disabled interface to fail.
Setting the default interface to limited in limited-portals.conf causes the failing test cases to pass

I have yet to investigate which interfaces are being called in these tests. The naive fix is just to set the default interface to limited, which I don't think might be a very good idea.

[preferred]
- default=none
+ default=limited
org.freedesktop.impl.portal.Account=limited
org.freedesktop.impl.portal.FileChooser=limited
org.freedesktop.impl.portal.Lockdown=limited
org.freedesktop.impl.portal.Settings=limited

The alternative is to either figure out if the disabled interfaces are invoked and remove occurrences of these invocations, or to fix the FileChooser interface to not fail when the default backend is none.

Since fixing tests or the FileChooser interface is unrelated to this PR, it is probably better to file a separate issue.

SoumyaRanjanPatnaik · 2024-02-09T22:00:23Z

@jp7677 thanks for pointing out the failing tests were skipped on my system. It turns out I had to enable the installed-tests feature for those tests to not be skipped on my system. It might be a good idea to add this to the contributor documentation.

This is how I ran the tests:

meson setup . build --prefix /usr -Dinstalled-tests=true
meson test -C build

jp7677 · 2024-02-10T17:19:17Z

Hi @SoumyaRanjanPatnaik I'm looking (without having former experience with this project) at your patch and the tests.

Your patch says:

static gboolean
portal_interface_prefers_none (const char *interface)
{
  const PortalInterface *iface = find_matching_iface_config (interface);

  if (iface != NULL && g_strv_contains ((const char * const *) iface->portals, "none"))
    {
      g_debug ("Found 'none' in configuration for %s", iface->dbus_name);
      return TRUE;
    }

  if (config != NULL && g_strv_contains ((const char * const *) config->default_portal->portals, "none"))
      return TRUE;

  return FALSE;
}

As far as I'm reading this, it translates to: disable this interface when the interface itself is disabled (org.freedesktop.impl.portal.FileChooser=none) or no fallback is set (default=none).

Looking at the test configuration:

[preferred]
default=none
org.freedesktop.impl.portal.Account=limited
org.freedesktop.impl.portal.FileChooser=limited
org.freedesktop.impl.portal.Lockdown=limited
org.freedesktop.impl.portal.Settings=limited

this means that all interfaces are disabled because one of the two conditions (the second one) is true. I think (not sure though) that the second if statement should only return true when that specific interface is not mentioned in the configuration file (or something similar). So I think the test failure is justified.

Edit: May be something like this is needed (essentially adding iface == NULL as condition to your version), the tests are good with this change and the test debug output shows expected output when I'm playing with 'none':

@jp7677 Thanks for correctly pointing this out. I prematurely blamed the tests (really stupid of me 😢). Tests seem to pass after updating portal_interface_prefers_none with the following.

static gboolean
portal_default_prefers_none ()
{
  if (config != NULL && g_strv_contains ((const char * const *) config->default_portal->portals, "none"))
    {
      g_debug ("Found 'none' in configuration for default");
      return TRUE;
    }

  return FALSE;
}

static gboolean
portal_interface_prefers_none (const char *interface)
{
  const PortalInterface *iface = find_matching_iface_config (interface);
  if (iface == NULL)
    return portal_default_prefers_none();

  if (g_strv_contains ((const char * const *) iface->portals, "none"))
    {
      g_debug ("Found 'none' in configuration for %s", iface->dbus_name);
      return TRUE;
    }

  return FALSE;
}

@SoumyaRanjanPatnaik no worries, I’m happy to help to bring this forward. Thanks a lot for your work in the first place to address this issue!
(I guess #1282 can be closed now ;) )

jp7677 · 2024-02-23T07:53:52Z

@GeorgesStavracas @ebassi is there anything left that needs to be done for this commit to get in? FWIW, I'm running this commit on top of xdg-desktop-portal-1.18.2 together with labwc for more than a week now and it works as intended without noticing any negative side effects.

src/portal-impl.c

Don't use fallback portal implementations in the following cases: - the preferred portals for an interface contains `none` - no preference is set for the interface but the default preference contains `none`

SoumyaRanjanPatnaik · 2024-02-23T20:28:24Z

@GeorgesStavracas Thanks for the review. Pushed the changes.

SoumyaRanjanPatnaik · 2024-02-23T20:33:51Z

Please follow the project code style:

Just curious, does this project have any documentation or formatter for enforcing the coding style? I searched for some documentation on code but found no leads in this regard.

jp7677 · 2024-03-08T06:53:22Z

@ebassi @GeorgesStavracas gentle ping...
