[gentoo-user] Python 2.7 support

Hi list,

I eard some (long) time ago that portage is not compatible with python 2.7, so i
masked it (python) in /etc/portage/package.mask. What i would like to know now
is is portage now compatible with this version of python ? Or if not, where can
i follow the status of this compatibility ? I looked on b.g.o but didn't find
anything related to this.

Many thanks in advance.

There is no python-2.7

I think you mean python-3.0

Once you make this change, google will tell you what you need to know

Sorry but instead of python 2.7 (which does not exists), i was talking about
python 3 support in portage. Is it safe to remove earlier version of python to
only keep version 3 ?

Thanks and sorry for the mistake.

Don't waste your or our time by trying to install alpha packages.

Out of curiosity I tried this a while back.  Portage had been updated a 
couple time since then but at the time, portage was not happy at all.  I 
seem to recall some other programs not being happy either but I can't 
recall which ones.

Since it is keyworded and masked. I would leave it alone.

No.

Google will tell you why.

There is no python 2.7 (well, 2.7 alpha 1 was released a few days ago).

What you "heard", actually what portage tells you is this.

      * Most programs do not work with Python 3.x yet
      * You should not "eselect python set 3.x" (i.e. set your system
        python to 3.x)
      * You should definitely *not* unmerge python 2.x
      * It's perfectly fine to have 2.x and 3.x installed at the same
        time (they are in different slots) so long as your system python
        remains 2.x

In addition, portage (at least the 2.2-rc series) has a python3 USE
flag, which means portage *is* designed to work with Python 3.x.  It's
still in development, but I've been using it for a while.  Once in a
while I've run into a bug, reported it and it got fixed.  I haven't had
any issues with it in a while though.

You probably didn't find anything at b.g.o because it's not a bug. It's
a feature ;-) (and also because you got your information wrong).  So
there's no reason to mask python3 (unless you want to).  If it were
buggy the Gentoo devs would have masked it for you ;-)

No. When you installed python3 it pretty much tells you *not* to do
this.  You get a big fat WARNING:

        WARNING!
        Many Python modules haven't been ported yet to Python 3.*.
        Python 3 hasn't been activated and Python wrapper is still
        configured to use Python 2. You can manually activate Python 3.1
        using `eselect python set python3.1`. It is recommended to
        currently have Python wrapper configured to use Python 2. Having
        Python wrapper configured to use Python 3 is unsupported.

And they devs have done so.  Python 3 is masked and even keyworded.  It 
is a hint at least.

Thanks all for your answers. Anyway, is there a mean to be kept informed about
the status of the "migration" ? (any "bugs" on b.g.o where i can CC myself)

It's keyworded, but not masked. The recommendation, for ~arch users, is
that you have it installed but leave 2.6 as the default.

It shows this here:

[M~] dev-lang/python-3.1.1-r1 (3.1)

Isn't that masked and keyworded?  I'm x86 here and synced yesterday.

Have you masked it in /etc/portage? It's not masked here, no sign of
it in /usr/portage/profile/package.mask, and I have it installed on ~amd64
and ~x86 systems.

Actually, it is installed here.  It's not in use but after my little 
testing, I left it on here.
