Merge lp:~gmb/launchpad/add-bnl-to-structsubs-bug-672507 into lp:launchpad

[Graham Binns]

The bug_notification_level field is now available for structural subscriptions when the advanced subscriptions feature flag is switched on.

this branch makes the bug_notification_level field available in the
structural subscription ui when the
malone.advanced-subscriptions.enabled flag is turned on.

== .bzrignore ==

 - i've added the generated testrunner configs to .bzrignore, since i
   have strict commits enabled and they were annoying the hell out of
   me.

== lib/lp/bugs/browser/tests/test_bugsubscription_views.py ==

 - i've updated the bugsubscription_views tests after noticing that a
   test that should have been carried out once per iteration of a loop
   was happening outside the loop (as it happens it still passes, but
   now the testing is more thorough).

== lib/lp/registry/browser/structuralsubscription.py ==

 - i've made structuralsubscriptionview descend from
   advancedsubscriptionmixin so that the bug_notification_level field
   becomes available.
 - i've added a current_user_subscription property, in accordance with
   the requirements of advancedsubscriptionmixin.
 - i've updated the callsites for
   istructuralsubscriptiontarget.addbugsubscription() to also pass the
   bug_notification_level where available.

== lib/lp/registry/browser/tests/test_structuralsubscription.py ==

 - i've added tests to cover the changes to structuralsubscriptionview,
   covering the subscription of people and teams to a
   structuralsubscriptiontarget.

== lib/lp/registry/interfaces/structuralsubscription.py ==

 - i've updated the declaration of
   istructuralsubscriptiontarget.addbugsubscription() to include the
   bug_notifcation_level field.

== lib/lp/registry/model/structuralsubscription.py ==

 - i've updated the implementation of
   istructuralsubscriptiontarget.addbugsubscription() to make use of the
   bug_notification_level field.

There's no lint.

[Jelmer Vernooij (jelmer)]

It seems like it would be useful to have some infrastructure for running tests against all things that support structural subscription. I reviewed another branch a while back that also did it manually using a seperate TestCase subclass for each.
