def __init__(self, services=None):
"""
Register a list of services, given their definitions.
Traditional charm authoring is focused on implementing hooks. That is,
the charm author is thinking in terms of "What hook am I handling; what
does this hook need to do?" However, in most cases, the real question
should be "Do I have the information I need to configure and start this
piece of software and, if so, what are the steps for doing so?" The
ServiceManager framework tries to bring the focus to the data and the
setup tasks, in the most declarative way possible.
Service definitions are dicts in the following formats (all keys except
'service' are optional)::
{
"service": <service name>,
"required_data": <list of required data contexts>,
"data_ready": <one or more callbacks>,
"data_lost": <one or more callbacks>,
"start": <one or more callbacks>,
"stop": <one or more callbacks>,
"ports": <list of ports to manage>,
}
The 'required_data' list should contain dicts of required data (or
dependency managers that act like dicts and know how to collect the data).
Only when all items in the 'required_data' list are populated are the list
of 'data_ready' and 'start' callbacks executed. See `is_ready()` for more
information.
The 'data_ready' value should be either a single callback, or a list of
callbacks, to be called when all items in 'required_data' pass `is_ready()`.
Each callback will be called with the service name as the only parameter.
After all of the 'data_ready' callbacks are called, the 'start' callbacks
are fired.
The 'data_lost' value should be either a single callback, or a list of
callbacks, to be called when a 'required_data' item no longer passes
`is_ready()`. Each callback will be called with the service name as the
only parameter. After all of the 'data_lost' callbacks are called,
the 'stop' callbacks are fired.
The 'start' value should be either a single callback, or a list of
callbacks, to be called when starting the service, after the 'data_ready'
callbacks are complete. Each callback will be called with the service
name as the only parameter. This defaults to
`[host.service_start, services.open_ports]`.
The 'stop' value should be either a single callback, or a list of
callbacks, to be called when stopping the service. If the service is
being stopped because it no longer has all of its 'required_data', this
will be called after all of the 'data_lost' callbacks are complete.
Each callback will be called with the service name as the only parameter.
This defaults to `[services.close_ports, host.service_stop]`.
The 'ports' value should be a list of ports to manage. The default
'start' handler will open the ports after the service is started,
and the default 'stop' handler will close the ports prior to stopping
the service.
Examples:
The following registers an Upstart service called bingod that depends on
a mongodb relation and which runs a custom `db_migrate` function prior to
restarting the service, and a Runit service called spadesd::
manager = services.ServiceManager([
{
'service': 'bingod',
'ports': [80, 443],
'required_data': [MongoRelation(), config(), {'my': 'data'}],
'data_ready': [
services.template(source='bingod.conf'),
services.template(source='bingod.ini',
target='/etc/bingod.ini',

'data_ready': services.template(source='spadesd_run.j2',

'start': runit_start,
'stop': runit_stop,
