[pytorctl/master] Option to get get_network_status as an iterator

commit 45d7753b7c947b141210017d1b987673c51d97c5 Author: Damian Johnson <atagar(a)torproject.org> Date: Wed Jun 15 19:27:12 2011 -0700 Option to get get_network_status as an iterator Setting the 'getIterator' argument drops the memory usage of calling get_network_status by 71% (from 3.5 MB to 1 MB).

[pytorctl/master] TorCtl connect method inflexible

commit 565e18a6ff6189dd11d8a43ca77eed287743b479 Author: Damian Johnson <atagar(a)torproject.org> Date: Thu Jun 16 07:50:58 2011 -0700 TorCtl connect method inflexible The connect method is a nice helper for cli initiation, but lacks sufficient call visibility to help in more general use cases. In particular it... - sends feedback to stdout - prompts for the controller password on stdin - suppresses exceptions To get around this I'm adding a more generic 'connectionComp' that does the icky bits of the connection negotiation I was trying to hide while still giving the caller what it needs to handle the connection process however it'd like.
