[Python-modules-team] Bug#709376: python-dap: Incomplete namespace_packages causes spurrious warning messages

[Mike Neish]

Package: python-dap
Version: 2.2.6.7-1
Severity: minor
Tags: upstream patch

Dear Maintainer,

With python-dap installed, I get the following warning message:

Module dap was already imported from None, but 
/usr/lib/python2.7/dist-packages
is being added to sys.path

The easiest way to trigger this message is to run "import pkg_resources".

A gentoo bug report at https://bugs.gentoo.org/show_bug.cgi?id=54161#c29
suggests that the 'dap' package needs to be added to the top of
/usr/lib/python2.7/dist-packages//dap-2.2.6.7.egg-info/namespace_packages.txt
(or whatever the equivalent location is).

The easiest way to fix this is to change the 'namespace_packages' parameter
being used in setup.py, in the Debian source package.

I've attached a patch which adds the root 'dap' package to 
namespace_package.
This fixes the warning message in my local tests.

Thanks,
Mike
