Bug 522376 – USE_PYTHON removal of 3.2 causes depclean to fail without manual rebuilds

• Product: Gentoo Linux
• Status: RESOLVED OBSOLETE

[Description Aaron Pelton 2014-09-08 12:36:37 UTC]

after running upgrade world a few days ago, it was suggested I remove 3.2 from PYTHON_USE, so I did. It mentioned python-update so I ran that.

Today I decided to run a depclean which it wouldn't do due to 3 of the following dep issues 

Sample: 
Calculating dependencies... done!
 * Dependencies could not be completely resolved due to
 * the following required packages not being installed:
 * 
 *   dev-python/setuptools[python_targets_python2_7(-),python_targets_python3_2(-),python_targets_python3_3(-),python_targets_python3_4(-),-python_single_target_python2_7(-),-python_single_target_python3_2(-),-python_single_target_python3_3(-),-python_single_target_python3_4(-),-python_single_target_pypy(-)] pulled in by:
 *     dev-python/pygments-1.6_p20140324

Rebuilding the first two and running depclean brought up docutils and after recompiling that, I was able to run depclean.

As of this writing, I only had to rebuild the following...
dev-python/pygments
dev-python/jinja
dev-python/docutils


Reproducible: Didn't try

Steps to Reproduce:
1. Haven't tried because I'm not sure how to reproduce without reverting entire system.



Not sure if this is really worth reporting but it seemed "inconsistent" with a clean upgrade path. 

I'm running ~amd64, I did a full rebuild on 2014-08-09 and have been upgrading since, about 600 packages (50%ish kde)

Yes I did a deep/new/update use rebuild. but did not do --with-bdeps=y

[Comment 2 Jeroen Roovers (RETIRED) 2014-09-08 13:29:12 UTC]

I'm not sure this can be fixed.

[Comment 3 Michał Górny 2014-09-08 20:40:59 UTC]

@dev-portage, can you think of any way the user could end up with inconsistent dep tree like this? Can bdeps be relevant? Or dynamic-deps?

I think bdeps is a likely culprit. If you don't use --with-bdeps=y, then parts of your dependency graph may break like this. This is why the depclean message advises you to run the following command:

  emerge --update --newuse --deep --with-bdeps=y @world

It's possible for dynamic-deps to lead to similar complaints from depclean, but this looks more like a bdeps issue to me.

USE_PYTHON is gone.
