Description Brian Bockelman 2018-06-15 02:17:57 UTC
Spec URL: http://t2.unl.edu/sources/libmacaroons.spec
SRPM URL: http://t2.unl.edu/sources/libmacaroons-0.3.0-1.el7.src.rpm
Description: Macaroons are flexible authorization credentials that support decentralized delegation, attenuation, and verification.

They provide a power and lightweight mechanism for generating bearer tokens and were first described by Google researchers in 2014 (https://ai.google/research/pubs/pub41892).

libmacaroons is a flexible C library for creating, manipulating, and verify these tokens.  I am working to use it as a dependency in a different project (Xrootd) for authentication tokens, meaning it would be quite useful if we can have it in Fedora/EPEL and avoid embedded sources.

The packaging is relatively simple (I enabled the Python bindings) and it appears functional.  I have run rpmlint against the spec file, SRPM, and binary RPMs and see no glaring errors or blockers.

Comment 1 Robert-André Mauchin 🐧 2018-06-15 13:33:27 UTC
 - Group: is not used in Fedora

 - BuildRequires:	python-devel is deprecated. Use:

BuildRequires:	python2-devel

 - %package -n python2-macaroons should include the python provide:

%{?python_provide:%python_provide python2-macaroons}

 - make %{?_smp_mflags} → %make_build

 - make install DESTDIR=%{buildroot} → %make_install

 - Instead of:

%post -p /sbin/ldconfig


%postun -p /sbin/ldconfig

   Use:

%ldconfig_scriptlets

   See https://fedoraproject.org/wiki/Changes/Removing_ldconfig_scriptlets#Upgrade.2Fcompatibility_impact

 - You must install the LICENSE file in %files:

%files
%license LICENSE
%{_libdir}/%{name}.so.*

 - The Requires should include %{?_isa}

%package devel
Summary:	Development libraries linking against libmacaroons
Requires:	%{name}%{?_isa} = %{version}-%{release} 

 - Simplify Source/URL

URL:		https://github.com/rescrv/libmacaroons
Source0:	%url/archive/releases/%{version}/%{name}-%{version}.tar.gz

 - Add a comment above the patch to explain what it's for

Comment 2 Robert-André Mauchin 🐧 2018-06-15 13:36:04 UTC
 - Add README to %doc

 - Python 2 will be EOL soon, is there no Python 3 package?

Comment 3 Brian Bockelman 2018-06-15 14:42:35 UTC
Robert, many thanks for the review!  It seems that I must be using an older version of rpmlint... will correct these as soon as I can.

That said, for these two items:
- python2-devel
- ldconfig_scriptlets

I am planning to submit this for EPEL7, where these don't apply (or, rather, don't work).  How should I proceed?  Apply the fixes for Fedora then later revert them for EPEL support?

For Python3 support: my understanding is that Python3 support is available in the upstream master but not part of any released code.  I'm reluctant to maintain a backport of the python3 code myself.

%ldconfig_scriptlets works on EPEL. See https://src.fedoraproject.org/rpms/epel-rpm-macros/c/8c54d820ba193370a39e1547472163f1e0fd67ef

python2-devel does work on EPEL (it's a shim for python-devel but it's easier to have the same for both Fedora and EPEL).

Comment 5 Brian Bockelman 2018-06-15 15:03:07 UTC
Ah, I see that our local mirror has an outdated version of epel-rpm-macros.  That explains the missing ldconfig_scriptlets.

Ok, I can fix these too.

Comment 6 Brian Bockelman 2018-06-15 15:11:08 UTC
Ok, I have uploaded the revised spec file and SRPM to the original URLs:

Spec URL: http://t2.unl.edu/sources/libmacaroons.spec
SRPM URL: http://t2.unl.edu/sources/libmacaroons-0.3.0-1.el7.src.rpm

Robert, I believe I have addressed all of your review suggestions.  Please let me know if there was something I overlooked

The %{?_isa} part is for the -devel package which is arched, not the python2 one which is noarch:

%package -n python2-macaroons
Summary:	Python 2 bindings for libmacaroons
Requires:	%{name} = %{version}-%{release}
%{?python_provide:%python_provide python2-macaroons}

%description -n python2-macaroons
%{summary}

%package devel
Summary:	Development libraries linking against libmacaroons
Requires:	%{name}%{?_isa} = %{version}-%{release} 

 - Simplify Source:

URL:		https://github.com/rescrv/libmacaroons
Source0:	%url/archive/releases/%{version}/%{name}-%{version}.tar.gz

→ notice the first tar.gz is removed


 - Build error:

checking for the distutils Python package... no
BUILDSTDERR: configure: error: cannot import Python module "distutils".

   Add before %configure:

export PYTHON=/usr/bin/python2

   to force Python2 detection.

Comment 8 Brian Bockelman 2018-06-15 17:54:57 UTC
Alright, latest version:
- Adds isa dependency to -devel subpackage.  Note that the python package is arch-specific as it's an extension module.
- Second attempt to fix the Source.  I think I got it right this time.  Didn't know GitHub could do that!
- Added "export PYTHON=..." to the build.  Double-checked build on both RHEL7 and FC28 this time.

Spec file and source RPM URL remain unchanged.

Comment 9 Robert-André Mauchin 🐧 2018-06-15 18:20:01 UTC
Perfect, package approved.

Comment 10 Gwyn Ciesla 2018-06-15 21:32:37 UTC
(fedscm-admin):  The Pagure repository was created at https://src.fedoraproject.org/rpms/libmacaroons

Comment 11 Brian Bockelman 2018-06-17 03:37:00 UTC
Package has been successfully built into rawhide.  Closing out ticket with resolution 'rawhide'.
