Smugmug web service ported to O2 : Host authentication required

Sun Jun 10 10:03:19 BST 2018

Hi Gilles,

So I have finished porting google and smugmug to O2. I have pushed to
gsoc18-exporttools-o2 branch and I'm running statistic check now. For
google photo, I noticed something strange :

   1. I can upload to album created with digiKam but not album created on
   the web (Google Photo).
   2. When importing, images are downloaded but not appear in digiKam view.
   So I guess they are not synchronized with database (?)

Besides, I don't have account created on Picasa Web when it hadn't been
into Google Photo, so all my test are with Google Photo. I don't know if
there are any other bugs with repos like that.

So, could you make some tests on my new codes to verify? I added a TODO
list as you said, so that we can keep track of what I haven't done yet.

Best,
Thanh
