Description Jeff Bastian 2016-02-25 18:02:01 UTC

Description of problem:
Four object files -- bitmap.o, find_bit.o, hweight.o and rbtree.o -- are installed as part of the python-perf rpm.

$ rpm -qlp python-perf-4.5.0-0.rc5.git0.2.fc24.x86_64.rpm 
/usr/lib64/python2.7/site-packages
/usr/lib64/python2.7/site-packages/bitmap.o
/usr/lib64/python2.7/site-packages/find_bit.o
/usr/lib64/python2.7/site-packages/hweight.o
/usr/lib64/python2.7/site-packages/perf-0.1-py2.7.egg-info
/usr/lib64/python2.7/site-packages/perf.so
/usr/lib64/python2.7/site-packages/rbtree.o

This seems to have been introduced with the 4.2.0 kernel with just hweight.o and rbtree.o:

$ rpm -qlp python-perf-4.2.6-300.fc23.x86_64.rpm 
/usr/lib64/python2.7/site-packages
/usr/lib64/python2.7/site-packages/hweight.o
/usr/lib64/python2.7/site-packages/perf-0.1-py2.7.egg-info
/usr/lib64/python2.7/site-packages/perf.so
/usr/lib64/python2.7/site-packages/rbtree.o

The 4.1 kernel was the last clean build with just the .so file:

$ rpm -qlp python-perf-4.1.13-100.fc21.x86_64.rpm 
/usr/lib64/python2.7/site-packages
/usr/lib64/python2.7/site-packages/perf-0.1-py2.7.egg-info
/usr/lib64/python2.7/site-packages/perf.so


Version-Release number of selected component (if applicable):
python-perf-4.2 and newer

How reproducible:
always

Steps to Reproduce:
1. rpm -ql python-perf

Actual results:
leftover object files from the kernel build are installed in the python site-packages directory

Expected results:
only perf.so and the egg-info file are installed

Ew.  Thanks for the report.  I have an idea as to why this is, but I don't have a fix in hand yet.

Comment 2 Jeff Bastian 2016-02-26 20:50:58 UTC

I've been poking through the Makefiles to see why this might be happening, but I haven't figured it out yet.  We could add an rm command to the rpm spec file to clean up the *.o files, but that's just masking the problem.

Right, exactly.

I described the problem and the reason for it to upstream.  Jiri replied with a patch that should fix things.  I'll grab it Monday and give it a shot.

Comment 4 Josh Boyer 2016-02-29 13:27:18 UTC

I've added the patch in Rawhide.  Should make the 4.5-rc6 build.
