Description Pádraig Brady 2014-06-26 15:14:06 UTC

The changes done for cleanup bug #1061051 should be reverted
as the existing structure is required to support arch specific
submodules like python-backports-lzma

The specific issue is that one can't import

  %{buildroot}%{python_sitearch}/backports/lzma/...

if there is no

  %{buildroot}%{python_sitearch}/backports/__init__.py

See bug #1061051 for details on how to address this

Fixed in 7.1 branch: 0f19456405003452ecc5d3f72f833b5adef87970

Comment 6 Martin Frodl 2014-10-29 14:08:02 UTC

I would like to point out that the upgrade fails if python-backports-lzma is installed because the files /usr/lib64/python2.7/site-packages/backports/__init__.py{,c,o} conflict. I don't think the update should be shipped as long as python-backports-lzma owns these files.

Comment 8 Martin Frodl 2014-12-18 13:43:07 UTC

Is there a way to ensure that python-backports-lzma -- iff installed -- will be upgraded to python-backports-lzma-0.0.2-8.el7 whenever python-backports is upgraded to python-backports-1.0-7.el7 in order to prevent the scenario outlined in bug 1158538?

Currently, python-backports-lzma simply depends on python-backports without a version specification, meaning that python-backports upgrade does not automatically trigger python-backports-lzma upgrade. Apparently, making python-backports depend on python-backports-lzma >= 0.0.2-8 is not enough, since it would install python-backports-lzma even if it were not present on the system in the first place.

Can you think of a solution to this problem?

Comment 9 Endi Sukma Dewata 2015-01-05 16:24:40 UTC

I'm not sure if it will trigger python-backports-lzma upgrade, but we probably can add a conflicts tag in python-backports to explicitly say that it will not work with older python-backports-lzma.

Comment 10 Martin Frodl 2015-01-12 11:54:44 UTC

That sounds like a reasonable solution to me. Shall the erratum be respun, then?
