 I've just tried simple example[1] with simple feed[2] in system w/o
 any 0install remains and it fails for the first time[3] but runs ok for 2nd.

 I missed something in example code or its a unpredictable behaviour
 (since [3] cailms for missed ROX-Lib dependensy but
 solve_and_download_impls() should make all downloads)?

An async task needs to be a Python generator, which means it needs to
include a yield statement somewhere (even if it's never called).

Normally key confirmation has to be async because it has to wait for
the key information to arrive and it has to wait for the user to
confirm.

I'll update handler.py so that it doesn't need to be async, but
meanwhile just putting yield at the end will fix the problem.

thanks, I added yield to confirm_import_feed() and it works fine

  Aleksey,
 
  I tried out your patches in a Debian Sid chroot with
 
    zeroinstall-injector-0.42.1-1
 
  installed and got the following exception in shell.log when running your 
  test
  case:
 
    AssertionError: Solver is not ready!
    {Interface http://rox.sourceforge.net/2005/interfaces/ROX-Lib: None, 
  Interface /home/sugar/Activities/Terminal.activity/activity/0depend.xml: 
  v1 (/home/sugar/Activities/Terminal.activity/activity)}
 
  The problem seems to be that you haven't told the policy object to solve the
  feeds. You can do that with
 
    policy.solve_with_downloads()
 
  and maybe in other ways too.
 
 That's right:
 
 - need_download() will do a solve and return True if you're missing
 feeds or implementations
 - solve_with_downloads() will solve and download any extra feeds it
 needs repeatedly until it has all the information it needs
 - solve_and_download_impls() will additionally download the selected
 implementations afterwards

I've just tried simple example[1] with simple feed[2] in system w/o
any 0install remains and it fails for the first time[3] but runs ok for 2nd.
