[Merge] lp:~jtv/launchpad/pre-827347 into lp:launchpad
Jeroen T. Vermeulen has proposed merging lp:~jtv/launchpad/pre-827347 into lp:launchpad.
Requested reviews:

Bug #827347 in Launchpad itself: "Link to DSD pages even if none require attention"
https://bugs.launchpad.net/launchpad/+bug/827347
For more details, see:
https://code.launchpad.net/~jtv/launchpad/pre-827347/+merge/71724
= Summary =
IDistroSeriesDifferenceSource.getForDistroSeries accepts a filter argument for status. It defaults to None. But surprisingly, it does not interpret None as "any status." Instead, None is read as DistroSeriesDifferenceStatus.NEEDS_ATTENTION. This causes no end of confusion, and also makes it harder to search for DSDs without regard for status. The weirdness was ossified into a test, but what documentation there is suggests that None is supposed to mean any status.
== Proposed fix ==
Make None mean "any status." No documentation changes needed. Some test cleanups though.
== Pre-implementation notes ==
DistroSeriesDifferencesVocabulary did not pass a status, but its documentation suggested that there would be no filtering by status. Gavin worked on this recently, and so was able to tell me that it was fooled by the unclear interface. The change in this branch should make it work as was always intended.
== Implementation details ==
The actual code change is tiny and appears at the top of the diff.
Only in packagecopyjob did I see a case where the status argument was left out but the caller clearly meant to get NEEDS_ATTENTION DSDs. There are a few tests elsewhere that do not pass status but are just as valid with "any status" as they are with the previous default. I kept those unchanged.
I also rewrote a whole bunch of getForDistroSeries tests to get rid of the complex test data that enabled or compounded this situation.
I'm still running tests to find out whether I missed anything. Since DSDs are a new feature, I'll count on the test suite to expose any problems with the change.
== Tests ==
{{{
./bin/test -vvc lp.registry.tests.test_distroseriesdifference
./bin/test -vvc lp.registry -t DistroSeriesDifferencesVocabulary
./bin/test -vvc lp.registry.browser.tests -t distroseries
}}}
== Demo and Q/A ==
The DistroSeries:+localpackagediffs page is a good place to exercise the effects on the DSD views. Go through the various statuses available in the search radio buttons, searching for each, and see that they all still select the appropriate differences.
Also verify the links from the page for a derived distroseries to the missing / changed / unique packages. Their counts may be affected. I'll be changing these links in my next branch for the same bug, since we want them to behave differently.
