Description Kevin Fenzi 2016-12-21 20:36:47 UTC
When libxml2 is rebuilt with python3.6 all things that use it's bindings get: 

Python 3.6.0rc1 (default, Dec 10 2016, 14:50:33) 
[GCC 6.2.1 20160916 (Red Hat 6.2.1-2)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import libxml2
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib64/python3.6/site-packages/libxml2.py", line 1, in <module>
    import libxml2mod
ImportError: /usr/lib64/python3.6/site-packages/libxml2mod.so: undefined symbol: _PyVerify_fd
>>> 

This is due to upstream python dropping this symbol: 

http://bugs.python.org/issue23524

I am not 100% sure here, but it looks like they dropped it in favor of just returning an error when an invalid fd is used. As a quick hack to get things working again in rawhide I have commited a simple patch that removes the call. 

Sorry if that breaks anything else or isn't the proper fix.

Comment 1 Fedora End Of Life 2017-02-28 10:50:18 UTC
This bug appears to have been reported against 'rawhide' during the Fedora 26 development cycle.
Changing version to '26'.

Comment 2 Rex Dieter 2017-04-11 13:14:53 UTC
Kevin, you committed a workaround,

https://src.fedoraproject.org/cgit/rpms/libxml2.git/commit/?id=05bd5b911b635683e37431e9757284779b820072

Can we close this bug or would you rather keep it open for tracking purposes?

Comment 3 Kevin Fenzi 2017-04-11 15:28:09 UTC
Well, the patch was super hacky, so I was hoping to have the maintainer talk to upstream about it or confirm that it was the right fix. 

I suppose we could close it, but perhaps should file an upstream bug so someday this might be fixed better or in an upstreamable way?

Comment 4 Rex Dieter 2017-04-15 15:33:21 UTC
OK, agreed (marking MoveUpstream)
