I started playing with aptdaemon on Ubuntu 13.10 recently, and I'm baffled. Calling simulate() on a transaction doesn't update the dependencies list. Debug from aptd shows that several events are being emitted, including a PropertyChanged event for Dependencies, but my handler is not called. Here's some code that demonstrates the problem:
import aptdaemon.client
def printcall(*args, **kwargs):
print("call(*%r, **%r)" % (args, kwargs))
client = aptdaemon.client.AptClient()
# I have make installed, but not abiword.
txn = client.install_packages(["make", "abiword"])
txn.connect("dependencies-changed", printcall)
txn.simulate()
print(txn.dependencies)
print(txn.packages)
For me, it prints an empty dependencies list (actually, a single list containing 6 empty lists), whereas running apt-get install abiword from the command-line comes up with several dependencies. Also, the dependencies-changed event is never fired:
dbus.Struct((dbus.Array([], signature=dbus.Signature('s')), dbus.Array([], signature=dbus.Signature('s')), dbus.Array([], signature=dbus.Signature('s')), dbus.Array([], signature=dbus.Signature('s')), dbus.Array([], signature=dbus.Signature('s')), dbus.Array([], signature=dbus.Signature('s')), dbus.Array([], signature=dbus.Signature('s'))), signature=None, variant_level=1)
dbus.Struct((dbus.Array([dbus.String(u'make'), dbus.String(u'abiword')], signature=dbus.Signature('s')), dbus.Array([], signature=dbus.Signature('s')), dbus.Array([], signature=dbus.Signature('s')), dbus.Array([], signature=dbus.Signature('s')), dbus.Array([], signature=dbus.Signature('s')), dbus.Array([], signature=dbus.Signature('s'))), signature=None, variant_level=1)
Is this a bug, or am I missing something (like an event loop)?
