Support MATE keyring with native password manager

[stanton]

What steps will reproduce the problem?

1. Install Ubuntu MATE 14.10.
2. Download and install JOSM an Native Password Manager plugin.
3. Start JOSM

What is the expected result?

I would expect the plugin to work with MATE's password manager.

What happens instead?

Upon start, I get the following message:

No native password manager could be found! Depending on your Operating System / Distribution, you may have to create a default keyring / wallet first.

Please provide any additional information below. Attach a screenshot if possible.

I suspect this is because MATE support would need to be added. Since MATE is a fork of GNOME 2 and GNOME Keyring is supported, the code should be mostly there and can be reused – there is probably little difference between MATE and GNOME apart from identifiers.

Patches welcome. :)

I'll happily supply one, once I find out where the fault lies :-)

Turns out Ubuntu MATE 14.10 (which I use) uses gnome-keyring, so in theory it should work already. Looking at the source code, I found that the code looks for a library which *should* be in libgnome-keyring-dev, but installing that library doesn't fix the issue.

The "Passwords and Keys" app shows me some passwords (including an SMB password), thus it seems I have a default keyring.

Do I need to install extra packages or make some extra settings to make this work? I'd happily document it on the wiki if I knew how to get it to work...

Just looked into JOSM settings, there is one setting named plugins.native-password-manager.agent, which is unset. Where and how does the plugin detect which password manager to use? Does that code by any chance query the desktop environment?

Replying to stanton:

In the java function GnomeProvider.enabled(), which calls a native function gnome_keyring_is_available() from libgnome-keyring. It will be interesting to know at what line exactly it fails.

Does that code by any chance query the desktop environment?

Nope.

I found the code and see it has a few calls to Log.fine(). How do I get OpenJRE to display log messages of this level on the console? (Searched on the net and came up dry – on Android I'd know where to look, on the desktop I need some help...)
