This provides a key value +storage with support for versioned, transactional operation, +and can calculate deltas from previous values to simplify unit logic +when processing changes. + + +Hook Integration +---------------- + +There are several extant frameworks for hook execution, including + + - charmhelpers.core.hookenv.Hooks + - charmhelpers.core.services.ServiceManager + +The storage classes are framework agnostic, one simple integration is +via the HookData contextmanager. It will record the current hook +execution environment (including relation data, config data, etc.), +setup a transaction and allow easy access to the changes from +previously seen values. One consequence of the integration is the +reservation of particular keys ('rels', 'unit', 'env', 'config', +'charm_revisions') for their respective values. + +Here's a fully worked integration example using hookenv.Hooks:: + + from charmhelper.core import hookenv, unitdata + + hook_data = unitdata.HookData() + db = unitdata.kv() + hooks = hookenv.Hooks() + + @hooks.hook + def config_changed(): + # Print all changes to configuration from previously seen + # values. + for changed, (prev, cur) in hook_data.conf.items(): + print('config changed', changed, + 'previous value', prev, + 'current value', cur) + + # Get some unit specific bookeeping + if not db.get('pkg_key'): + key = urllib.urlopen('https://example.com/pkg_key').read() + db.set('pkg_key', key) + + # Directly access all charm config as a mapping. + conf = db.getrange('config', True) + + # Directly access all relation data as a mapping + rels = db.getrange('rels', True) + + if __name__ == '__main__': + with hook_data(): + hook.execute() + + +A more basic integration is via the hook_scope context manager which simply +manages transaction scope (and records hook name, and timestamp):: + + >>> from unitdata import kv + >>> db = kv() + >>> with db.hook_scope('install'): + ... # do work, in transactional scope. + ... db.set('x', 1) + >>> db.get('x') + 1 + + +Usage +----- + +Values are automatically json de/serialized to preserve basic typing +and complex data struct capabilities (dicts, lists, ints, booleans, etc). + +Individual values can be manipulated via get/set:: + + >>> kv.set('y', True) + >>> kv.get('y') + True + + # We can set complex values (dicts, lists) as a single key. + >>> kv.set('config', {'a': 1, 'b': True'}) + + # Also supports returning dictionaries as a record which + # provides attribute access. + >>> config = kv.get('config', record=True) + >>> config.b + True + + +Groups of keys can be manipulated with update/getrange:: + + >>> kv.update({'z': 1, 'y': 2}, prefix="gui.") + >>> kv.getrange('gui.', strip=True) + {'z': 1, 'y': 2} + +When updating values, its very helpful to understand which values +have actually changed and how have they changed.
