Support alternative bindings for Dbus about secretstorage

[mitya57]

My plan was to try jeepney, but perhaps TxDBus is also worth trying. I cannot make any promises on when I will have time to work on it, though.

Jeepney looks like it would be much cleaner than TxDBus

Initial version of Jeepney port is available in wip/jeepney branch. It passes tests on Travis, but some functions related to unlocking collections may not work properly yet.

I will not release it as a stable SecretStorage release, as Jeepney does not support Python 2, while keyring needs us to support it. So either it will be a beta version for some years, or a separate project on PyPI.

Cc @takluyver — you might be interested in seeing projects using Jeepney :)

Thanks! Nice work :-)

I think you've already seen my keyring_jeepney backend. That's much simpler than this, because I only aimed to support the simplified API that keyring provides, rather than exposing the richer xdg secrets interface. I also took some shortcuts around assuming that the items we wanted are already unlocked.

[mitya57]

Sure, I have seen it, but I want to expose the full Secret Service API here, including prompting, and at the same time I want to make API compatible to previous SecretStorage releases, so I used my own wrapper class instead of your Proxy.

Great :-) I wasn't suggesting this is unnecessary - I'm actually likely to use the richer SecretStorage API in a project I'm thinking about.
