Updating to this version of python stops portage from emerging anything.

Reproducible: Always

Comment 1 Andreas Proteus 2010-08-02 23:43:52 UTC
I misstyped the version.
  This should be :

My apologies.

Can someone fix it?
Comment 2 Antanas Uršulis 2010-08-02 23:46:12 UTC
You should've provided the error. Here is a sample one:

Same here. I can't emerge anything after the update.
Comment 4 Brian Harring (RETIRED) gentoo-dev 2010-08-03 01:23:25 UTC
This was caused by a blind importation of upstream 2.6 release branch-

Neither for me.  python2.6 is the only version on my system.

Is there a howto somewhere on how to repair a broken python?

This doesn't fix the issue for me.

Errm, nevermind. Applying your patch and switching back to python 2.6 makes emerge work again. Thanks! :D (Sorry for the noise)
Comment 11 Arfrever Frehtes Taifersar Arahesis (RETIRED) gentoo-dev 2010-08-03 02:05:33 UTC
Python upstream developers intentionally decided to change exception raised by array.fromfile() from EOFError to IOError:
http://svn.python.org/view?view=rev&revision=83032

Please note that there were Portage releases (e.g. 2.2_rc34), which were causing exceptions, and they weren't treated as QA violations.

Take the excuses to the devrel bug.  You didn't test the sole major dep of portage in your automated backporting and broke it.

remove the backported versions; they're autogenerated, obviously not tested for 2.6 (bug 330937, breaking portage for anyone runing unstable python at time of commit), and have been the source of a shitload of other rather odd bugs till identification of what was occuring (bug 330667).  ignoring a PDEPEND.bad for 3.1.2-r3 for >=app-admin/python-updater-0.8 also to get these removed

Comment 14 Keith Dart 2010-08-03 02:21:20 UTC
I just run into this also. What a bummer. 

Here's what I had to do to get portage working again. Hopefully you still have
your original source in your distfiles.

cd ~/build
tar xjf /home/ftp/pub/mirror/gentoo/distfiles/Python-2.6.5.tar.bz2
cd Python-2.6.5/
./configure --prefix=/usr --enable-shared --with-system-ffi --with-signal-module  --with-threads
make
make altinstall

That got it working well enough to (hopefully) sync again and get any
forthcoming fix.

Thanks, but don't use that nor distribute it to others please- that can orphan files pretty easily and there is a simpler/faster fix that doesn't require cleanup.

Do

wget http://dev.gentoo.org/~ferringb/fix-python-2.6.5_p20100801.patch -O - | patch /usr/lib/portage/pym/_emerge/SpawnProcess.py

instead.  This leaves no orphans, tweaks emerge w/ the patch mentioned, and gets you back to the point where you can merge a sane python version.

Comment 18 Mike Hammill 2010-08-03 10:05:09 UTC
The "quick way out" worked for me.  But of course it's not a good solution if you don't happen to have python 3.x installed or if you actually want to further test python 2.6.5_p20100801 (with the patch).  All in all, quite a mess.
Comment 19 Dieter Verfaillie 2010-08-03 11:04:01 UTC
The patch for SpawnProcess.py from #15 does not seem to be a complete solution:

>>> Unmerging sys-kernel/gentoo-sources-2.6.34-r2...
 * The 'prerm' phase of the 'sys-kernel/gentoo-sources-2.6.34-r2' package
 * has failed with exit value -1.
 * 
 * The problem occurred while executing the ebuild file named 'gentoo-
 * sources-2.6.34-r2.ebuild' located in the '/var/db/pkg/sys-kernel/gentoo-
 * sources-2.6.34-r2' directory. If necessary, manually remove the
 * environment.bz2 file and/or the ebuild file located in that directory.
 * 
 * Removal of the environment.bz2 file is preferred since it may allow the
 * removal phases to execute successfully. The ebuild will be sourced and
 * the eclasses from the current portage tree will be used when necessary.
 * Removal of the ebuild file will cause the pkg_prerm() and pkg_postrm()
 * removal phases to be skipped entirely.

Yeah it was never meant to be a final solution, it is just enough to be able to re-merge python (2.6.5-r2) and then portage proper.
Comment 21 tman 2010-08-03 12:03:24 UTC
i have solve the problem by taking python 3.1

eselect python set 2
emerge -uDN python
eselect python set 1

emerge -uDN world

and all is fine now

You really want to compare the bugs portage has leveled versus your own personal shitstorm?

Of those portage bugs, how many of them left users unable to upgrade?  How many users were affected?  It's not about bugs, it's about _impact_, how many people are affected, how bad the fallout, what is required to resolve it.  Portage hasn't had a version that was categorically unusable- your blind commits (lacking proper QA despite the blame shifting) however managed that quite nicely.  Reality is, you want to maintain a package that others depend on, you're responsible for checking your reverse deps.

You didn't, nor do you generally speaking.  Just knock it off.  It's pretty obvious you don't consider this an issue or are looking to blameshift, thus your point is made- take it to the devrel/QA bug.  No one here cares (nor frankly wants to hear it).

Marking resolved.  Broken python version was pulled from the tree the day it did it's damage.

Zac, you should open up a bug to sort out how you'll be dealing w/ older portage versions that will be hit by this.

I am certain the maintainer is redfaced and at the moment the size of his self esteem 
does not exceed the 1 nanometer, and he is definetely wrong in trying to shift the blame onto others instead of apologizing.  

I am also certain that from now on he will be extra carefull so that such oversights do not happen again. 

No real harm was done. Let us put this behind us and continue with this wonderfull distro that we all love.

The new python ebuilds need to have a !!<sys-apps/portage-2.1.9 blocker in RDEPEND.

This does absolutely nothing for me. It does not rebuild anything and it doesn't fix anything.

This works nicely, thanks!
Comment 31 Simone 2010-10-13 10:31:47 UTC
Got hit by this one yesterday with dev-lang/python-2.6.6. Should I open a new bug?
Comment 32 Dirkjan Ochtman (RETIRED) gentoo-dev 2010-10-13 11:49:41 UTC
Should not be a problem with 2.6.6-r1 (which is blocked by old portage).

I use Paludis so this bug had no impact on me, but this blocker does.  I admit not a big deal, but I propose that it would be better to handle the shift in exceptions within Portage.

Could be as easy as...

try:
    blah()
except EOFError, IOError:
    exception_blah()

Or you could get fancy and test the Python version.

We're already doing that with >=portage-2.1.9. Obviously, it's not possible to go back in time and update the older portage versions.

> Or you could get fancy and test the Python version.

Not necessary. The fix in >=portage-2.1.9 is already optimal.

I have python 2.6.6-r1 installed and I had the same problem.

My fix:

eselect python set 2
echo 'sys-apps/portage python3' >> /etc/portage/package.use/my.use
emerge portage
eselect python set 1

The emerge command (for me) threw a lot of weird warnings about postrm exiting incorrectly but the install completed.

This actually installs Portage 2.2.0_alpha2_p1 on the system and switches it to python3 so this is not the best solution for most people.
