Python Wheels in fedora
Starting with Fedora 22, Python packages will have the option to install itself into buildroot via Python wheels.[1] Wheels are the new binary distribution format for python modules, note that as such they are not suitable for use as Source archive.
Unless you have a good reason to use this method of installation, please use the one specified in Packaging:Python. Currently, installing with wheels uses a fedora-specific pip option[2] and upstream may choose to eventually implement it in a different way.
The text below describes the minimal specfile changes needed, if installation with wheel is desired.
BuildRequires
The package has to BuildRequire python?-pip and python?-wheel:
BuildRequires: python-pip
BuildRequires: python-wheel
%if %{?with_python3}
BuildRequires: python3-pip
BuildRequires: python3-wheel
%endif
Build section
The package has to use the bdist_wheel command, instead of install, this creates a wheel in the dist directory. A minimal build section thus becomes:
%{__python2} setup.py bdist_wheel
%if 0%{?with_python3}
pushd %{py3dir}
%{__python3} setup.py bdist_wheel
popd
%endif
Install section
Tha package has to use pip to install the newly created wheel. A minimal install section thus becomes:
%if 0%{?with_python3}
pushd %{py3dir}
pip3 install -I dist/%{python3_wheelname} --root %{buildroot} --strip-file-prefix
popd
%endif
pip2 install -I dist/%{python2_wheelname} --root %{buildroot} --strip-file-prefix
The --strip-file-prefix option is currently downstream only modification that strips given prefix from files in wheel RECORD.[3]
Files section
Unless covered by an already existing glob, you may also need to add the following entries to the files section:
%{python2_sitelib}/%{name}-%{version}.dist-info/
%{python3_sitelib}/%{name}-%{version}.dist-info/
