Missing __init__.py

[Adi Roiban]

When I'm running pylint I get the following warning:

warning: Not importing directory '/usr/share/pyshared/google': missing __init__.py
warning: Not importing directory '/usr/share/pyshared/lazr': missing __init__.py

All other folders from /usr/share/pyshared have an __init__.py file, so I guess that adding that file could solve this problem.

This is a possible fix:
sudo touch /usr/share/pyshared/google/__init__.py
sudo touch /usr/share/pyshared/lazr/__init__.py

The question is, which package should that file go in? There's no "lowest-level" lazr package - neither python-lazr.restfulclient nor python-lazr.uri depends on the other, and either one ought to arrange for the top-level __init__.py to exist. Do we need a python-lazr.common or something?

[Martin Pool (mbp)]

Is this connected to bug 796992? Perhaps that one is caused by an attempt to work around this?

I think a tiny top level python-lazr would be a reasonable answer.

[Robert Collins (lifeless)]

+1 on a package containing the top level lazr namespace. The python packaging guide/policy stuff has other options too, but I like the clarity of a top level package.

[Stefano Rivera (stefanor)]

lazr.restfulclient *should* depend on lazr.uri (LP: #876445). But there are other lazr packages in Ubuntu (only).

Piotr thinks that dh_python2's namespace feature will be sufficient for this. That way we avoid a top level empty package (there's no obvious binary package to build it from). the lazr stack may be unimportable during upgrades, would that be an issue?

[Gediminas Paulauskas (menesis)]

In other packages that have namespaces but not an obvious main package, I have added a separate binary package. Example is z3c.form that also builds a python-z3c package that only contains the __init__.py. This tiny package has a version that does not mean anything, but that's hardly a problem.

menesis@ore:~/src/ubuntu/precise/z3c.form
$ cat debian/python-z3c.form.install
debian/tmp/*
menesis@ore:~/src/ubuntu/precise/z3c.form
$ cat debian/python-z3c.pyinstall
src/z3c/__init__.py z3c

$ tail -n 5 debian/control
Package: python-z3c
Architecture: all
Depends: ${python:Depends}, python-pkg-resources, ${misc:Depends}
Description: z3c namespace package
 Namespace package for all z3c.* packages to depend on.

This was done before dh_python2, and I tried to remove it and rely on dh_python2 creating empty __init__.py files, but it is bad for upgrades, because that file may not be available. I've seen python break after removing a package from that namespace (cannot import site.py)

Also this was needed because van-pydeb helper adds namespace packages like python-z3c to Depends. python-lazr would have to be added to Depends of all lazr.* packages manually...

Status changed to 'Confirmed' because the bug affects multiple users.

[Anders Kaseorg (andersk)]

I think this is supposed to be solved by

$ cat /usr/share/python/ns/python-protobuf
google

Somehow I managed to get to a state where this didn’t work (bug 1017339), but reinstalling python-protobuf caused /usr/lib/python2.7/dist-packages/google/__init__.py to come back.

This bug was fixed in the package lazr.restfulclient - 0.13.1-1

---------------
lazr.restfulclient (0.13.1-1) experimental; urgency=low

  * New upstream release.
     - Now cache-safe for concurrent clients.
  * Upload to experimental, as we are in freeze.
  * Get rid of .pth files, dh_python2's namespace support is sufficient.
    (LP: #796992, #583426)
  * Depend on python-lazr.uri. (LP: #876445)
  * Update watch file to work with secure LP urls for the tarballs.
  * Bump Standards-Version to 3.9.4, no changes needed.
  * Bump machine readable copyright format to 1.0, no changes needed.
  * Updated copyright years.
