GitHub puppet-python

Puppet module for installing and managing Python, pip, virtualenvs and Gunicorn virtual hosts.

Change regex in python_version and python_release facts so it matches python release candidate version (e.g. Python 2.7.16rc1, Python 3.7.3rc1).

This test currently fails because of https://github.com/voxpupuli/puppet-python/issues/586

For Ubuntu 18.04 and Debian 10, ensure distutils is installed.

When testing pyvenv I ran into this problem when using Python 3 and noticed if you install python3-venv instead of python3.7-venv it pulls in python3-distutils but rather than changing the behavior of how to install python*-venv just pulling in the dependency works.

Failure with/without system packages
```
root@debian10:/# python3.7 -m venv --clear --system-site-packages /opt/globus-cli
The virtual environment was not created successfully because ensurepip is not
available. On Debian/Ubuntu systems, you need to install the python3-venv
package using the following command.

apt-get install python3-venv

You may need to use sudo with that command. After installing the python3-venv
package, recreate your virtual environment.

Failing command: ['/opt/globus-cli/bin/python3.7', '-Im', 'ensurepip', '--upgrade', '--default-pip']

root@debian10:/# python3.7 -m venv --clear /opt/globus-cli

Pull Request (PR) description

Fixes issue wherein the python::requirements class does not correctly install a requirements.txt file declared in Puppet to the declared venv, e.g.

puppet
file { "${project_dir}/requirements.txt":
ensure => present,
content => file("${module_name}/requirements.txt")
}
-> python::pyvenv { "${project_dir}/pyenv":
ensure => present,
version => '3.6'
}
-> python::requirements {"${project_dir}/requirements.txt":
virtualenv => "${project_dir}/pyenv",
}


This appears to be due to the logic for setting the local resource subscription - it checks if the requirements file is not declared before setting the local subscription which ultimately gates the pip installation. This behavior runs contrary to the provided Example(s), in which requirements.txt must exist or be declared in advance of invoking the class:
https://forge.puppet.com/modules/puppet/python/reference#pythonrequirements
puppet
python::requirements { '/var/www/project1/requirements.txt' :
virtualenv => '/var/www/project1',
proxy => 'http://proxy.domain.com:3128',
owner => 'appuser',
group => 'apps',
}


Changes

• Always set the local subscription in python::requirements, which is used to trigger the pip installation.
