Spec URL: https://jgrulich.fedorapeople.org/xdg-native-messaging-proxy.spec
SRPM URL: https://jgrulich.fedorapeople.org/xdg-native-messaging-proxy-0.1.0-1.fc43.src.rpm
Description: This is a small service which can be used to find native messaging host
manifests, as well as start and stop those native messaging hosts.

Applications running inside a sandbox might have a limited view of the host
which might prevent them from finding and executing native messaging hosts which
exist outside of the sandbox. This proxy is supposed to run outside of any
sandbox, which will make the native messaging hosts outside the sandbox
available to anyone with access to the dbus service.

Comment 2 Milan Crha 2026-03-16 17:54:09 UTC
> ... available to anyone with access to the dbus service.

A little nitpick, could you use "D-Bus" instead of "dbus" in the text, please? Quotes for clarity only. It may or may not be inherited from the upstream, in any case it'll be better typed as it should be in Fedora.

> License: LGPL-2.0-or-later

The GitHub repo says "LGPL-2.1 license", which reflects their COPYING file. The source files have: "SPDX-License-Identifier: LGPL-2.1-or-later" in the top comments. I would follow the source files.

> Requires: dbus

I'm not sure of that. It may get it as a transitive auto-dependency from glib2/gio, maybe? it surely does not use dbus library directly, but through glib2.

The rest in the template:

Fixed. I took it from the meson.build (https://github.com/flatpak/xdg-native-messaging-proxy/blob/main/meson.build#L6) while I was collecting dependencies.

I based it on xdg-desktop-portal, I think it's meant in this case that it needs a D-Bus session, but can be removed.

They certainly have a mismatch there upstream. It would be good to fix it on their end. The fedora-review found few more licenses, though I did check only the files in the src/.

It's also from the fedora-review and I also do not see any problem there. The project installs user unit systemd files, thus it's there. Maybe it's meant to check the usage of it, not as a real issue (which it does not explain at all in my eyes, why it considers it an issue, because the link only shows how to use it, which you did correctly).
