[gentoo-user] Python update question

[gentoo-user] Python update question

[Dale]

Howdy,

I'm just wanting to make certain I don't break my rig.  Info first:

root@fireball / # eselect python list
Available Python interpreters:
  [1]   python2.7 *
  [2]   python3.1
  [3]   python3.2
root@fireball / #

I ran --depclean and it wants to remove python 3.1.  I ran python
updater and recompiled the needed packages.  Since python 2.7 is the
default python, is it safe to remove python 3.1?  As we all know, python
and portage is really good friends and portage gets real upset when it
looses its friend.  I'd much rather ask this question than have to start
a thread on how to repair python with a dead portage.

So, safe to remove?  I'm thinking it is but just want the comfort of
taking someone else with me it is breaks.  lol

I really need to not post when I take my meds.  lol  The last line
should read "* someone else with me if it breaks."

Meds.  They help some things but hurt other things.  o_O

Thanks.

It's safe, your portage uses 2.7.

Thanks for the confirmation.  I was thinking it was but wanted to double
check.

Thanks again.

You should be safe but please do an

eselect python list --python3

and make sure you're set to 3.2 before removing 3.1.

Hmmm... mine shows it is set to 3.1...

  # eselect python list --python3
Available Python 3 interpreters:
   [1]   python3.1 *
   [2]   python3.2
myhost : Fri Mar 02, 13:07:51 : ~
  #

So, that would be

eselect python set --python3 2

to set it to 3.2 leaving 2.7 as the main active python, right?

Just making sure because I know that mucking up python is *not* a 
problem I want to have to deal with...

Last I heard we are not supposed to set python to 3 anything.  Has that
changed?

No, we're not supposed to set the *system* *default* to python3 yet.
Still, if you have multiple 3.x versions installed you would want to
set the python3 setting to the python version you want to default to
should some program absolutely require python3, so we've got 3 real
settings:

System default - still python-2.x
Python2 - same python-2.x version as the system default
Python3 - what ever version you want for programs requiring Python3

HTH,
Mark

But if I tell eselect to set it to 3 something then that is what the
system will try to use right?  Isn't that what eselect does?  I'm
recalling what was posted after you emerge python here.  The einfo/ewarn
thingy.

Again, this may have changed but what I'm wondering is if we need the
python 2 stuff any more if we can set this to python 3.  After all,
python 2 has to die eventually.  ^_^

did you miss my earlier reply?

Mine also shows it is set to 3.1...

  # eselect python list --python3
Available Python 3 interpreters:
   [1]   python3.1 *
   [2]   python3.2
myhost : Fri Mar 02, 13:07:51 : ~
  #

So, that I'm guessing the correct way to do this is:

eselect python set --python3 2

?

Dale,
   I'll try to make it clearer:

The command "eselect python set #" sets the system python profile.
This command allows you to choose any python currently on your system.
You should only choose a python2 setting at this time.

The commands:
eselect python list --python2
eselect python set --python2 #

only deal with python2

The command
eselect python list --python3
eselect python set --python3 #

only deal with python3

All three of those profiles (python, python2 & python3) are distinct
entities. They are different and can each be set any way you want. I
was only clarifying that before you removed python3.1 that you choose
python3.2 for your python3 profile.

Clearer?

HTH,
Mark

"The system" isn't granular enough (I've been dying to use that geek-
speak phrase :) when discussing portage, which is only part of a gentoo
"system".

List the files in sys-apps/portage and you'll see that none of them go
in /usr/lib/pythonN.N/site-packages like mere ordinary python packages.
They go instead in /usr/lib/portage, which is independent of your python
version.

However, try this trick:

#head -1 /usr/lib/portage/bin/emerge
#!/usr/bin/python3

You can see from that I've installed portage to use python3, even though:

#eselect python list
Available Python interpreters:
  [1]   python2.7 *
  [2]   python3.1

I still have my "system" python set to 2.7 like most of us, I suspect.

At this point, the portage package obeys the setting of the python3
useflag to decide which python to use and I have my python3 useflag
set, so portage announces "fixing shebangs" at the end of the emerge,
and that's where the #!/usr/bin/python3 comes from.

I see the difference now.  I already ran --depclean and portage still
works.  I'll run python-updater again tho.  I didn't know eselect
treated them separately like that.  Learn something every day.

Now to remember that.  :/
