ModuleNotFoundError: No module named 'Shared.DC.ZRDB'

Reference: #54 (comment)

The error ModuleNotFoundError: No module named 'Shared.DC.ZRDB' occurred because the Products.ZSQLMethods package may not be properly configured as a namespace package. I fixed this by:

1. Creating init.py files for the Shared, Shared.DC, and Products namespace packages with the proper pkg_resources.declare_namespace() calls
   Updating the setup.py to explicitly declare Shared and Shared.DC as namespace packages
2. Configuring package discovery in setup.py to find packages in the src directory

Hi @dataflake,
I suppose the reason for the ModuleNotFoundError might be a mismatch of the Zope-version and the PR goes into the wrong direction because the test fail. So, feel free to delete it.

No, you are bringing back old pkg_resources-style namespaces which have been deprecated a long time ago and which cause never-ending warning log entries. All namespace packages that are not archived have been switched to use implicit (PEP 420) namespace package conventions.

I am guessing you're running Zope 5.13 in your sandbox. That will not work because its Shared package is an old-style namespace package. You can only test Products.ZSQLMethods with either a master checkout of Zope or Zope 6.0b1/b2.

Closing this PR.
