[gentoo-user] World update and changed PYTHON_TARGETS

Hey list

during yesterday's upgrade I read the news about python 3.4 being the
new profile default. In its course a lot of python-related packages were
indeed rebuilt (up until then I had set PYTHON_TARGETS to 2.7, 3.3 and
3.4 manually due to blender, which already required 3.4). But in the
end, depclean will still not remove python 3.3. So I dug and after some
more cleanup (some packages had to be un-keyword to support 3.4) I got:

---[ $ emerge -cpv python:3.3 ]-------------------------------------------------
Calculating dependencies... done!
  dev-lang/python-3.3.5-r1 pulled in by:
    dev-python/lxml-3.3.5 requires >=dev-lang/python-3.3.2-r2:3.3
    dev-python/setuptools-7.0 requires >=dev-lang/python-3.3.2-r2:3.3
--------------------------------------------------------------------------------

What I don't understand:

---[ $ emerge -pvuD --changed-use --with-bdeps=y world ]------------------------
[...]
Total: 0 packages, Size of downloads: 0 kB

---[ $ emerge -p lxml setuptools ]----------------------------------------------

[ebuild   R   ~] dev-python/setuptools-7.0  PYTHON_TARGETS="-pypy3% -python3_3*"

The following keyword changes are necessary to proceed:
 (see "package.accept_keywords" in the portage(5) man page for more details)
# required by lxml (argument)
=dev-python/lxml-3.4.1 ~amd64

---[ $ eix -e lxml ]-------------------------------------------------------------
[I] dev-python/lxml
     Available versions:  3.3.5 ~3.3.6 ~3.4.0 ~3.4.1 {beautifulsoup3 doc examples +threads PYTHON_TARGETS="python2_7 python3_3 python3_4"}

--------------------------------------------------------------------------------

If I upgrade the "stable" lxml 3.3.5 to the keyworded 3.4.1, this
problem will probably go away. But I want to understand it. How can I
find out why portage thinks I need lxml 3.4.1? 3.3.5 knows about python
just 3.4 as well, it only uses a different shell syntax to express it:

3.3.5: PYTHON_COMPAT=( python{2_7,3_{2,3,4}} )
3.4.1: PYTHON_COMPAT=( python{2_7,3_3,3_4} )

---[ $ emerge -pvc lxml ]-------------------------------------------------------
Calculating dependencies... done!
  dev-python/lxml-3.3.5 pulled in by:
    app-text/calibre-1.20 requires >=dev-python/lxml-2.2.1

--------------------------------------------------------------------------------

Both inkscape and calibre only care about python 2.7.


Cheers and good night for now.

Perhaps you've noticed by now, but the change was reverted in the meantime.

Furthermore, eselect news shows that the news entry got deleted, too:

% eselect news list
News items:
  <snip>
  [36]     2014-11-23  (2014-11-23-python-targets - removed?)

At least that is the state as of my last sync at 23:00 UTC+1 last night.

Oh, great.  I changed my settings in make.conf, eselected 3.4, rebuilt
some packages, and depcleaned 3.3.  No bugs are apparent on my machine
so far, so I guess I'll keep it like this until something explodes or
there's another news item.

I did the same. Except I could not depclean 3.3 because it is still
used by something. So now I have 2.7, 3.3 and 3.4

- From what I understand from IRC chatter, the consensus is "no user
intervention is required", so they've elected to not post a news item.

For reference, the change was reverted as per [1], though there's been
no further significant followup from that that I'm aware of.

Thanks -- somehow I'd missed that post.  I think these are the bugs to
watch for progress:

(python-3.4) [TRACKER] Python 3.4 incompatible packages
<https://bugs.gentoo.org/show_bug.cgi?id=504336>

(python-3.4-stable) [TRACKER] Python 3.4 stable requests
<https://bugs.gentoo.org/show_bug.cgi?id=530258>
