"""\
Functions to expose over the RPC interface.
For all modify* and delete* functions that ask for an 'id' parameter to
identify the object to operate on, the id may be either
* the database row ID
* the name of the object (label name, hostname, user login, etc.)
* a dictionary containing uniquely identifying field (this option should seldom
be used)
When specifying foreign key fields (i.e. adding hosts to a label, or adding
users to an ACL group), the given value may be either the database row ID or the
name of the object.
All get* functions return lists of dictionaries. Each dictionary represents one
object and maps field names to values.
Some examples:
modify_host(2, hostname='myhost') # modify hostname of host with database ID 2
modify_host('ipaj2', hostname='myhost') # modify hostname of host 'ipaj2'
modify_test('sleeptest', test_type='Client', params=', seconds=60')
delete_acl_group(1) # delete by ID
delete_acl_group('Everyone') # delete by name
acl_group_add_users('Everyone', ['mbligh', 'showard'])
get_jobs(owner='showard', status='Queued')
See doctests/001_rpc_test.txt for (lots) more examples.
