Merge lp:~gary-lasker/software-center/recommended-installed-feedback into lp:software-center

[Gary Lasker]

* lp:~gary-lasker/software-center/recommended-installed-feedback:
   - signal the recommender service when a recommended item has been
     successfully installed (LP: #944060)

This branch implements the "implicit" recommender feedback feature. It detects the case where the user successfully installs a recommended item and fires a "submit_implicit_feedback" call to notify the recommender of the installed package.

This is the client-side implementation for bug 944060.

Note that this branch depends on the lp:~gary-lasker/software-center/update-to-latest-recommender-client branch as that branch adds the new recommender client code from lp:~canonical-ca-hackers/ubuntu-recommender/ubuntu-recommender-client. Also note that I made one small change to sreclient to fix the validate decorator for the pkgname argument to implicit_feedback so that it matches the validator for the other calls that use pkgname as an argument.

Finally, I added a unit test for the new call in test_recagent.py, however like a few of the other tests there, the test is not currently working with the server. Therefore, it remains disabled as the other tests are. I'll look at this tomorrow to try to see what the issue is with these tests.

Meanwhile, everything here should be working. To test, just select any recommended item in the lobby or category views and install it. Once the installation is complete, the corresponding implicit_feedback call will be fired.

Many thanks for your review!

Thanks for working on this branch. I'm very happy to see this feature
coming.

Thanks for this, if you fixed the sreclient_pristine.py, please also
send the diff to the server team (if you haven't done already) so that
they add it to their
lp:~canonical-ca-hackers/ubuntu-recommender/ubuntu-recommender-client
branch.

Maybe the staging server had problems. I just tested enabling them and
its working, but that may well be that its now fixed. While looking at
the test code I noticed that there is a bit of duplication in
there, I pushed a branch at
lp:~mvo/software-center/recagent-test-cleanup that removes most of
that.

I also noticed that the branch is missing a test for the new
functionality, it would be nice to add one to
tests/gtk3/test_recommendations_widget.py. Something like activate a
app, trigger a install transaction and verify that on finish the
self.recommender_agent.post_implicit_feedback() call was done.

Nice that this is more consistent now (plus that it will actually work).

That looks like we could use:

class RecommenderFeedback:
      INSTALLED = "installed"

(so that later "REMOVED" can be added there as well and its more
consitent with the rest of enums.py).

Yep, I proposed a branch for this and it has been merged by Lukasz.

I added a thorough test for this functionality in test_catview.py (this is where the other recommendations panel tests are, and imo it's consistent because the tests for the other lobby panels (What's New and Top Rated) are also located here. While in test_catview.py I did some cleanup and consolidation of duplicated code as well.

Oops, I noticed a typo in my last comment:

"...when a person clicks on a recommended item, we remember that they did that for that item for as long as the current USC session is active (it is now, however, persisted between sessions, I think would be a mistake)."

Should be (see the "*not*"):

"...when a person clicks on a recommended item, we remember that they did that for that item for as long as the current USC session is active (it is *not*, however, persisted between sessions, I think would be a mistake)."

Though maybe this was obvious, but I wanted to make sure that I'm clear.

Thanks again!

Thanks for adding the test and for the cleanup there, that looks very
good!

3096. By Gary Lasker on 2012-09-02

RED: add a failing test to show that the implicit recommender call is incorrectly being made from the top rated panel

3097. By Gary Lasker on 2012-09-03

the fix for the failing test case is to do the refactoring that we know is needed in CategoriesViewGtk to move the add_tiles_to_flowgrid and corresponding on_application_selected methods to where they belong, specifically, to the FlowableGrid class itself, this commit contains the brunt of this refactor, but there are some additional pieces needed to finish it up

3098. By Gary Lasker on 2012-09-04

GREEN: essential refactor complete and signals wired up, all test cases now working; removed the unused (with FIXME) 'application-selected' signal from catview as it is not used there (we only 'activate' apps from this widget), fix single-line cut-and-paste error in the test case

3099. By Gary Lasker on 2012-09-05

REFACTOR: make a new TileGrid subclass of FlowableGrid so that FlowableGrid remains generic, wire up the TileGrid for the various panels that it is used

3100. By Gary Lasker on 2012-09-05

REFACTOR: remove all need for the catview in the recommendations code

3101. By Gary Lasker on 2012-09-05

don't use hasattr in the FramedHeaderBox so that we can attach listeners to the more button when we need to, connect listeners for this, add a signal to the RecommenderPanelCategory (and subclass RecommenderPanelLobby) so that we can get their correct categories when clicking 'More' in those
