[MIR] python-funcsigs, python-linecache2, python-traceback2

honestly, are you going to split out the whole of the standard library into duplicated source packages? why are you building these packages for python3 at all?

@doko

All of these packages are a backport of the module current tip release of python, supported on all python versions that we care about in Ubuntu (and Debian).

This was discussed on the Debian Python ML:

  https://lists.debian.org/debian-python/2015/07/msg00006.html

with some input from lifeless who is the upstream developer of alot of this work; python3-unittest2 != unittest in Python 3.4 for example.

This is a shift we're seeing in terms of migration approach to py3; importing a single namespaced package that just works on whatever Python is *easy* for developers, even if it does make life harder for us in the distro.

(and just for reference, I'm not driving any of this - so please don't shoot me :-))

I am also troubled by the duplication in main. But since such python module backports aren't likely to be security sensitive, I'm slightly mollified. Since Debian and upstreams are starting to embrace the concept, it seems counterproductive to say "just port to python3 instead". Hopefully this will get them on the path to python3.

Though once everyone is ported to python3, they'll now be depending on all these clone modules. Ideally transitioning to the stdlib wouldn't be hard at that point.

Anyway. funcsigs looks OK.

python-linecache2 is good too. Runs its tests, has subscriber, is tiny, etc.

I've passed our small delta on to Debian, so hopefully we can sync it back up later.

python-traceback2 is also good. I've also passed its delta on to Debian.

It needs python-contextlib2 in main though. Will look at that next.

Whoops, nevermind. contextlib2 was already reviewed for MIR in bug 1473485.

All moved to main.
