The gettext.install() function installs a builtin _() function which translates a string in the translation domain supplied to the install() function. If gettext.install() is called multiple times, it's the last call to the function which wins and the last supplied translation domain which is used e.g. >>> import os >>> os.environ['LANG'] = 'ja.UTF-8' >>> import gettext >>> gettext.install('keystone', unicode=1, localedir='/opt/stack/keystone/keystone/locale') >>> print _('Invalid syslog facility') 無効な syslog ファシリティ >>> gettext.install('nova', unicode=1, localedir='/opt/stack/nova/nova/locale') >>> print _('Invalid syslog facility') Invalid syslog facility Usually this function is called early on in a toplevel script and we assume that no other code will call it and override the installed _(). However, in Nova, we have taken a shortcut to avoid having to call it explicitly from each script and instead call it from nova/__init__.py. This shortcut would be perfectly fine if we were absolutely sure that nova modules would never be imported from another program. It's probably quite incorrect for a program to use nova code (indeed, if we wanted to support this, Nova code shouldn't use the default _() function) but nevertheless there are some corner cases where it happens. For example, the keystoneclient auth_token middleware tries to import cfg from nova.openstack.common and this in turn causes gettext.install('nova') in other projects like glance or quantum. To avoid any doubt here, let's just rip out the shortcut and always call gettext.install() from the top-level script. Change-Id: If4125d6bcbde63df95de129ac5c83b4a6d6f130a |

OpenStack Nova README
OpenStack Nova provides a cloud computing fabric controller, supporting a wide variety of virtualization technologies, including KVM, Xen, LXC, VMware, and more. In addition to its native API, it includes compatibility with the commonly encountered Amazon EC2 and S3 APIs.
OpenStack Nova is distributed under the terms of the Apache License, Version 2.0. The full terms and conditions of this license are detailed in the LICENSE file.
Nova primarily consists of a set of Python daemons, though it requires and integrates with a number of native system components for databases, messaging and virtualization capabilities.
To keep updated with new developments in the OpenStack project follow @openstack on Twitter.
To learn how to deploy OpenStack Nova, consult the documentation available online at:
In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:
Developers wishing to work on the OpenStack Nova project should always base their work on the latest Nova code, available from the master GIT repository at:
Developers should also join the discussion on the mailing list, at:
Any new code must follow the development guidelines detailed in the HACKING.rst file, and pass all unit tests. Further developer focused documentation is available at:
For information on how to contribute to Nova, please see the contents of the CONTRIBUTING.rst file.
