[Ian Booth <ian.booth@xxxxxxxxxxxxx>]

Ian Booth has proposed merging lp:~wallyworld/launchpad/package-defaults-192076 into lp:launchpad.

Requested reviews:
  Launchpad code reviewers (launchpad-reviewers)
Related bugs:
  Bug #192076 in Launchpad itself: "component of new binary packages should default to source component"
  https://bugs.launchpad.net/launchpad/+bug/192076

For more details, see:
https://code.launchpad.net/~wallyworld/launchpad/package-defaults-192076/+merge/131509

== Implementation ==

I added a small extra block of code to the NascentUpload find_and_apply_overrides() method - if there is no ancestory for binary uploads, see if there is a current corresponding source publication and use the component from that if available. 

== Tests ==

I added some new tests to test_uploadprocessor, since this test module seemed to be the main place where the end-end operation of the nascent upload and processing functionality was tested.

== Lint ==

Checking for conflicts and issues in changed files.

Linting changed files:
  lib/lp/archiveuploader/nascentupload.py
  lib/lp/archiveuploader/nascentuploadfile.py
  lib/lp/archiveuploader/tests/test_uploadprocessor.py
