Description Kevin Fenzi 2016-12-01 18:32:56 UTC

IN RHEL7.3, python-cffi was added. It's a much newer version and it breaks python-pygit2. :( 

python-cffi-0.8.6-1.el7 is the old version that was in epel
python-cffi-1.6.0-5.el7 is the new version now in rhel 7.3

Using the new python-cffi results in a traceback ending in: 

IOError: [Errno 2] No such file or directory: '/usr/lib64/python2.7/site-packages/pygit2/__pycache__/pygit2_cffi_c721781dxbf062fb5.c'

Comment 2 Erik Johnson 2017-02-10 16:27:48 UTC

Is anyone going to fix this?

Comment 3 Hugh Crissman 2017-02-10 17:16:18 UTC

Please fix this ASAP. I'm a paying customer and this broke a production system. I have a workaround in place until a proper solution is available.

I was hoping someone else would, but I guess I will now. ;)

Keep in mind that EPEL packages are community supported and have no particular SLA or the like. 

After some testing, it seems just a simple rebuild fixes this, so I am going to push that. We can look at updating to newer versions or whatever in other bugs, I am just going to rebuild to fix this particular issue. I have also added a versioned dep here so the new python-pygit2 should require/pull in the new python-cffi.
