Bug 1381029

Please have a look at the python packaging guidelines. Try the template from https://fedoraproject.org/wiki/Packaging:Python#Example_common_spec_file.

The most obvious issues:
- this is a python library, the package should be called python-more-itertools
- python3 must be supported
- description should be wrapped to 72-80 columns
- please start from the template linked above, that will make many things simpler and more correct.

I am having a problem with the new SPEC file. It does not compile. Here is the error I get. 

File "/usr/lib/python3.5/more.py", line 162
    min_or_max = partial(max if reverse else min, key=lambda (a, b): a)
                                                             ^
SyntaxError: invalid syntax

I have uploaded the new spec file here:

$ fpaste  more-itertools.spec 
Uploading (2.6KiB)...
http://paste.fedoraproject.org/444104/67316914/ -> https://paste.fedoraproject.org/444104/67316914

Any suggestions would be appreciated.

Tuple unpacking in parameter lists is gone in python3. But 2to3 takes care of the translation. Unfortunately it seems you need a separate build dirs for the two versions. It seem easiest to just copy the sources twice:

The spec file name must much package name.

Consider using a macro for the description:
%global _description \
text of the description here \
blah blah blah

%description %_description

%description -n python2-... %_description

etc.

%python_provide for python3 subpackage has wrong version, and generated Provides are wrong.

However, my mock build on koji has problems for F23 and EPEL7: builds fine without error for F24, F25 and rawhide. What is the problem with the provides?
Here is the error with F23: I think the issue is possibly similar with EPEL7.

Thanks for any more helpful suggestions?

The package builds fine in F23 mock for me, and also now in koji scratch (http://koji.fedoraproject.org/koji/taskinfo?taskID=16005364). Yesterday there was some issue with F23 koji package set, maybe your build failure was caused by that.

Review:
+ package name is OK
+ license is aceptable (MIT)
+ license is specified correctly
+ latest version
+ python packaging template is used
+ %python_provide is used
+ provides/requires look OK
+ builds and installs OK
+ %check passes

Package is APPROVED.
