A change was merged to the main Ansible core code that can cause
a potential hang if any libraries are called that use threading.
This change was:
4b0aa1214c
This affected the os_object module by causing a hang on the shade
create_object() API call (which in turn calls swiftclient which
uses threading). The fix is to make sure all modules have a main()
that is wrapped with an "if __name__ == '__main__'" check.
The exception message, when shade fails, will contain much more
specific information about the failure if the exception is treated
as a string. The 'message' attribute alone is usually not helpful.
Updating os_ironic module to the most recent version accounting for
changes in Ansible devel branch and the shade library since the
original creation of the module.
