Merge lp:~verterok/ubuntuone-client/sd-do-oauth into lp:ubuntuone-client

[Guillermo Gonzalez]

Use oauthdesktop in syncdaemon to request a token if we haven't already got one.

[Guillermo Gonzalez (verterok)]

This branch adds support for oauthdesktop to syncdaemon.
e.g: If there is no token in the keyring, syncdaemon will call oauthdesktop to get the token, and listen for the oauthdesktop DBus signals.

[John O'Brien (jdobrien)]

works great.

I get this when doing make check. I'm not sure why though, as I'm running it as me.

I get this when doing make check. It looks like for some reason the "share" directory here isn't writable by me.

[Guillermo Gonzalez (verterok)]

Fixed and pushed.

Thanks

Hi,
That test is unrelated to my changes.
I'll file a bug about it and skip the test.

Hi, Bug #494469 filed and assigned.

Thanks

skip test_warning_on_log_file_when_failing_delete, Bug #494469

[dobey (dobey)]

OK. Looks like the test isn't failing now, and several runs all passed, so I'll go ahead and Approve. Thanks.
