pypi URL 404

pypi URL 404

Hi Guix,

I've created the following package definition using the pypi importer. 
However, when I try to build it with guix build -f … the build fails 
because it cannot download the source. The downloader gets redirected to a 
url that returns 404. However, the pypi importer was able download the 
source.

Package definition produced by the importer:

(define-module (ducktype)
   #:use-module ((guix licenses) #:prefix license:)
   #:use-module (guix packages)
   #:use-module (guix download)
   #:use-module (guix build-system python))

(package
   (name "python-mallard-ducktype")
   (version "1.0.1")
   (source
     (origin
       (method url-fetch)
       (uri (pypi-uri "mallard-ducktype" version))
       (sha256
         (base32
           "04mjj8apzm0cb4vk73vydgfiw8cyznfy3zrb99xs9d2k8x7cxc99"))))
   (build-system python-build-system)
   (home-page "")
   (synopsis
     "Parse Ducktype files and convert them to Mallard.")
   (description
     "Parse Ducktype files and convert them to Mallard.")

It seems no proper source tarball is available on PyPI, only a "wheel":

<https://pypi.org/project/mallard-ducktype/>

The importer uses those to extract requirements.txt, and apparently
returns the wheel hash when it fails to find a proper source.  That is
probably a bug.

In this case it is probably easiest to download the source from the
upstream repository, or ask the maintainer to upload a tarball.

I've opened #35673 about that: https://issues.guix.gnu.org/issue/35673

I'll adjust the source location. I've also asked upstream to upload a 
tarball: http://projectmallard.org/pipermail/mallard-list/2019-May/000287.html
