  - Refactoring:

    - Make resolves no longer use edge_connection_t unless they are actually

      _on_ on a socks connection: have edge_connection_t and (say)

      _on_ a socks connection: have edge_connection_t and (say)

      dns_request_t both extend an edge_stream_t, and have p_streams and

      n_streams both be linked lists of edge_stream_t.

    . Make cells get buffered on circuit, not on the or_conn.

      O Implement cell queues

      o Implement cell queues

      o Keep doubly-linked list of active circuits on each or_conn.

      o Put all relay data on the circuit cell queue, not on the outbuf.

      o Don't move them into the target conn until there is space on the

    - A better UI for authority ops.

      - Follow weasel's proposal, crossed with mixminion dir config format

    . Bridges users (rudimentary version)

      o Ability to specify bridges manually

      o Config option 'UseBridges' that bridge users can turn on.

        o uses bridges as first hop rather than entry guards.

      - give extend_info_t a router_purpose again

      o react faster to download networkstatuses after the first bridge

        descriptor arrives

      - be more robust to bridges being marked as down and leaving us

      o be more robust to bridges being marked as down and leaving us

        stranded without any known "running" bridges.

    - Bridges operators (rudimentary version)

      - Ability to act as dir cache without a dir port.

      D Should do reachability testing but only on the purpose==bridge

        descriptors we have.

    - Bridges

      - Clients can ask bridge authorities for updates on known bridges.

      - More TLS normalization work: make Tor less easily
