Define some helper functions
>>> def test_unique(items) :
... return not [True for e in items if items.count(e) > 1]
Connect to datastore using DBus and wait for it to get ready:
>>> import dbus
>>> DS_DBUS_SERVICE = "org.laptop.sugar.DataStore"
>>> DS_DBUS_INTERFACE = "org.laptop.sugar.DataStore"
>>> DS_DBUS_PATH = "/org/laptop/sugar/DataStore"
>>> bus = dbus.SessionBus()
>>> ds = dbus.Interface(bus.get_object(DS_DBUS_SERVICE, DS_DBUS_PATH), DS_DBUS_INTERFACE)
>>> ds.wait_ready()
>>> assert ds.check_ready()
Make sure we're starting from an empty datastore:
>>> assert ds.find({}, [], byte_arrays=True) == ([], 0)
Create something to play with:
>>> o1_uid = ds.create({'title': 'DS test object 1', 'mime_type': 'text/plain', 'activity': 'org.sugarlabs.DataStoreTest1'}, '', False)
>>> assert isinstance(o1_uid, basestring)
>>> o2_uid = ds.create({'title': 'DS test object 2', 'mime_type': 'text/plain', 'activity': 'org.sugarlabs.DataStoreTest2'}, '', False)
>>> assert isinstance(o2_uid, basestring)
>>> o3_uid = ds.create({'title': 'DS test object 3', 'mime_type': 'text/plain', 'activity': 'org.sugarlabs.DataStoreTest2'}, '', False)
>>> assert isinstance(o3_uid, basestring)
>>> assert test_unique([o1_uid, o2_uid, o3_uid])
Check everything is there:
>>> sorted(ds.find({}, ['title', 'activity'], byte_arrays=True)[0])
[dbus.Dictionary({dbus.String(u'title'): dbus.ByteArray('DS test object 1', variant_level=1), dbus.String(u'activity'): dbus.ByteArray('org.sugarlabs.DataStoreTest1', variant_level=1)}, signature=dbus.Signature('sv')), dbus.Dictionary({dbus.String(u'title'): dbus.ByteArray('DS test object 2', variant_level=1), dbus.String(u'activity'): dbus.ByteArray('org.sugarlabs.DataStoreTest2', variant_level=1)}, signature=dbus.Signature('sv')), dbus.Dictionary({dbus.String(u'title'): dbus.ByteArray('DS test object 3', variant_level=1), dbus.String(u'activity'): dbus.ByteArray('org.sugarlabs.DataStoreTest2', variant_level=1)}, signature=dbus.Signature('sv'))]
>>> ds.get_filename(o1_uid, byte_arrays=True)
dbus.String(u'')
>>> ds.get_filename(o2_uid, byte_arrays=True)
dbus.String(u'')
>>> ds.get_filename(o3_uid, byte_arrays=True)
dbus.String(u'')
Test get_uniquevaluesfor().
>>> sorted(ds.get_uniquevaluesfor('activity', {}))
[dbus.String(u'org.sugarlabs.DataStoreTest1'), dbus.String(u'org.sugarlabs.DataStoreTest2')]
Change some entries:
>>> ds.update(o1_uid, {'title': 'DS test object 1 updated', 'mime_type': 'text/plain', 'activity': 'org.sugarlabs.DataStoreTest1', 'tags': 'foo'}, '', False)
>>> ds.update(o2_uid, {'title': 'DS test object 2', 'mime_type': 'text/plain', 'activity': 'org.sugarlabs.DataStoreTest1', 'tags': 'bar baz'}, '', False)
>>> ds.update(o3_uid, {'title': 'DS test object 2', 'mime_type': 'text/html', 'activity': 'org.sugarlabs.DataStoreTest3'}, '', False)
>>> sorted(ds.find({}, ['title', 'activity'], byte_arrays=True)[0])
[dbus.Dictionary({dbus.String(u'title'): dbus.ByteArray('DS test object 1 updated', variant_level=1), dbus.String(u'activity'): dbus.ByteArray('org.sugarlabs.DataStoreTest1', variant_level=1)}, signature=dbus.Signature('sv')), dbus.Dictionary({dbus.String(u'title'): dbus.ByteArray('DS test object 2', variant_level=1), dbus.String(u'activity'): dbus.ByteArray('org.sugarlabs.DataStoreTest1', variant_level=1)}, signature=dbus.Signature('sv')), dbus.Dictionary({dbus.String(u'title'): dbus.ByteArray('DS test object 2', variant_level=1), dbus.String(u'activity'): dbus.ByteArray('org.sugarlabs.DataStoreTest3', variant_level=1)}, signature=dbus.Signature('sv'))]
Retrieve metadata for a single entry, ignoring variable data:
>>> d=dict(ds.get_properties(o3_uid, byte_arrays=True))
>>> del d['uid'], d['timestamp']
>>> d
{dbus.String(u'title'): dbus.ByteArray('DS test object 2', variant_level=1), dbus.String(u'mime_type'): dbus.ByteArray('text/html', variant_level=1), dbus.String(u'activity'): dbus.ByteArray('org.sugarlabs.DataStoreTest3', variant_level=1)}
Find entries using "known" metadata:
>>> sorted(ds.find({'mime_type': 'text/plain'}, ['title', 'activity', 'mime_type', 'tags'], byte_arrays=True)[0])
[dbus.Dictionary({dbus.String(u'title'): dbus.ByteArray('DS test object 2', variant_level=1), dbus.String(u'activity'): dbus.ByteArray('org.sugarlabs.DataStoreTest1', variant_level=1), dbus.String(u'mime_type'): dbus.ByteArray('text/plain', variant_level=1), dbus.String(u'tags'): dbus.ByteArray('bar baz', variant_level=1)}, signature=dbus.Signature('sv')), dbus.Dictionary({dbus.String(u'title'): dbus.ByteArray('DS test object 1 updated', variant_level=1), dbus.String(u'activity'): dbus.ByteArray('org.sugarlabs.DataStoreTest1', variant_level=1), dbus.String(u'mime_type'): dbus.ByteArray('text/plain', variant_level=1), dbus.String(u'tags'): dbus.ByteArray('foo', variant_level=1)}, signature=dbus.Signature('sv'))]
>>> sorted(ds.find({'mime_type': 'text/html'}, ['title', 'activity', 'mime_type', 'tags'], byte_arrays=True)[0])
[dbus.Dictionary({dbus.String(u'title'): dbus.ByteArray('DS test object 2', variant_level=1), dbus.String(u'mime_type'): dbus.ByteArray('text/html', variant_level=1), dbus.String(u'activity'): dbus.ByteArray('org.sugarlabs.DataStoreTest3', variant_level=1)}, signature=dbus.Signature('sv'))]
>>> sorted(ds.find({'uid': o3_uid}, ['title', 'activity', 'mime_type'], byte_arrays=True)[0])
[dbus.Dictionary({dbus.String(u'title'): dbus.ByteArray('DS test object 2', variant_level=1), dbus.String(u'mime_type'): dbus.ByteArray('text/html', variant_level=1), dbus.String(u'activity'): dbus.ByteArray('org.sugarlabs.DataStoreTest3', variant_level=1)}, signature=dbus.Signature('sv'))]
Find entries using "unknown" metadata (=> returns all entries):
>>> sorted(ds.find({'title': 'DS test object 2'}, ['title', 'activity', 'mime_type', 'tags'], byte_arrays=True)[0])
[dbus.Dictionary({dbus.String(u'title'): dbus.ByteArray('DS test object 2', variant_level=1), dbus.String(u'mime_type'): dbus.ByteArray('text/html', variant_level=1), dbus.String(u'activity'): dbus.ByteArray('org.sugarlabs.DataStoreTest3', variant_level=1)}, signature=dbus.Signature('sv')), dbus.Dictionary({dbus.String(u'title'): dbus.ByteArray('DS test object 2', variant_level=1), dbus.String(u'activity'): dbus.ByteArray('org.sugarlabs.DataStoreTest1', variant_level=1), dbus.String(u'mime_type'): dbus.ByteArray('text/plain', variant_level=1), dbus.String(u'tags'): dbus.ByteArray('bar baz', variant_level=1)}, signature=dbus.Signature('sv')), dbus.Dictionary({dbus.String(u'title'): dbus.ByteArray('DS test object 1 updated', variant_level=1), dbus.String(u'activity'): dbus.ByteArray('org.sugarlabs.DataStoreTest1', variant_level=1), dbus.String(u'mime_type'): dbus.ByteArray('text/plain', variant_level=1), dbus.String(u'tags'): dbus.ByteArray('foo', variant_level=1)}, signature=dbus.Signature('sv'))]
Delete an entry:
>>> ds.delete(o1_uid)
>>> sorted(ds.find({}, ['title', 'activity'], byte_arrays=True)[0])
[dbus.Dictionary({dbus.String(u'title'): dbus.ByteArray('DS test object 2', variant_level=1), dbus.String(u'activity'): dbus.ByteArray('org.sugarlabs.DataStoreTest1', variant_level=1)}, signature=dbus.Signature('sv')), dbus.Dictionary({dbus.String(u'title'): dbus.ByteArray('DS test object 2', variant_level=1), dbus.String(u'activity'): dbus.ByteArray('org.sugarlabs.DataStoreTest3', variant_level=1)}, signature=dbus.Signature('sv'))]
