Description of problem: Python module rhsm is used by other projects (e.g. virt-who) and it should not call exit(), but it should raise some exception, because application using rhsm module cannot resurrect from calling exit() by some external module. Version-Release number of selected component (if applicable): # subscription-manager version server type: Red Hat Subscription Management subscription management server: 2.0.37-1 subscription management rules: 5.24.1 subscription-manager: 1.19.12-1.el7 python-rhsm: 1.19.6-1.el7 How reproducible: always Steps to Reproduce: 1. Start Python interpreter: $ python 2. Import rhsm submodule called 'certificate' >>> import python_rhsm.certificate 3. Try to get certificate from some non-existent file: >>> c = python_rhsm.certificate.create_from_file('/foo/non_existing_cert.pem') No such file or directory Actual results: Python interpreter is terminated as well any other program trying to do similar thing. Expected results: Calling python_rhsm.certificate.create_from_file('/foo/non_existing_cert.pem') should raise some exception. Additional info: This can happen in production, when system is not registered and there is no file: /etc/pki/consumer/cert.pem. There are no other exit() call in rhsm module only one in: python-rhsm/src/rhsm/certificate2.py
