Sync python-apt 1.0.1 (main) from Debian unstable (main)

[Julian Andres Klode]

Please sync python-apt 1.0.0 (main) from Debian unstable (main)

Explanation of the Ubuntu delta and why it can be dropped:
  * Cherrypick d1d4e0848c5c2963d8411470bcf15a0e8c3538af from git
    to resolve the testsuite failures with the new pep8 version.
-> Obviously uptream
  * debian/control: Drop apt build-depends to 1.0.9.10ubuntu6 to
    build in wily; can be dropped after apt >= 1.0.10 is merged.
->Upstream too
  * To properly conform to PEP 479 and Python 3.5, __iter__() methods
    should return when exhausted instead of raising StopIterator. This
    diff can be dropped when Debian bug #792606 is fixed released.
-> Upstream too

Furthermore, this is somewhat annoying, because the current
version in wily has an invalid (non-PEP440) upstream version
number, and uploading 1.0.0 will fix that. Otherwise, you get
setuptools to complain again, which we do not want.

That release also deprecates some code that will be dropped
in the next release, so it's kind of important to have that.

Changelog entries since current wily version 1.0.0~beta3.1ubuntu1:

I'll take a look at this. One question of the top. The changelog says this:

[ John R. Lenton ]
  * Discard stderr when calling system-image-cli (LP: #267935)

That's clearly not the right bug. Do you have more details and a correct bug # for that issue?

[Barry Warsaw (barry)]

I ran the DEP-8 tests for the Debian version of the package in a Wily VM and got some failures related to the deprecation warnings. This would prevent promotion from wily-proposed. So either a `Restrictions: allow-stderr` should be added or you should add a -W argument to suppress the warnings.

Also I noticed that there aren't any DEP-8 tests for Python 3. Those should be added too.

Let me work up fixes for both those, and I'll apply them to an Ubuntu delta and propose a patch to Debian.

Oops, I mised utils/pyversions. That picks up python3.

[Julian Andres Klode (juliank)]

Yeah, our build system is somewhat broken. It's from very early when Python 3 support was introduced and just hacked to make work with new changed.

I did not catch the stderr thing, as it is not shown by default in normal testing environments. I can adjust the tests to check the deprecation marking, instead of just printing it, that would make much more sense.

I requires a construct roughly like:

        with warnings.catch_warnings(record=True) as caught_warnings:
            warnings.simplefilter("always")
           ... <code raising warning> ...

        self.assertEqual(len(caught_warnings), 1)
        self.assertTrue(issubclass(caught_warnings[0].category,
                                   DeprecationWarning))

[Barry Warsaw (barry)]

Release team: in IRC, we agreed to wait until 1.0.1 is uploaded and then we can drop the ubuntu delta and just syncpackage 1.0.1. Julian's going to upload that now and I'll sync it as soon as LP picks up the new version.
