[tor-project] [TSoP] stem.client - status report #1

Hi everyone!

This is my first status report for the stem.client TSoP project [1].

# Updates

A lot of these first two weeks has been improving development processes,
workflows, and coordination.

A new Trac keyword "dev" now exists for stem tickets related to
developers/development. [2][3]
I'll be adding more and addressing some of these soon.

I continued some work on the stem.control caching behavior, to wrap up
#25821 [4] and tie out a remnant event into a new ticket, #26129 [5].

I've been planning out some of the architecture/design of stem.client
[6], as well as reviewing existing code [7].

For the former, I'm especially considering how to make stem.client most
useful within the Tor and Python ecosystems.

I've looked at the "sans-io" style in hyper-h2 that meejah mentioned
[8][9][10][11], along with similar resources [12][13][14].

I've also been looking at a few of the modules in the Python stdlib and
projects in the ecosystem, to try to understand their potential
integration points.

# What's next

For both architecture and code review, I have a bit more work to do.
I'll confer further with Damian for these.
Architecture discussion will be started on a private pad and then opened
up to the larger community.

Afterwards, I'll be moving onto these cells:

And then I'll be working on CERTS, AUTH_CHALLENGE, NETINFO cells and the
"v3 handshake".

# Other Tor things

I'd like to point out some other Tor things I'm doing, too, that aren't
under the scope of stem :).

I've had some mild involvement in the University of Michigan getting
their exit node [15] up and running again.
And Cryptoparty Ann Arbor will be having an event on Sat., June 9th, at
the public library. [16]

# Closing

As with before, I've been active and reachable over IRC, where my nick
is dmr.

I'm still attending the network-team meetings, and since I've been
asking some clarifications on the tor-spec [17], I'll probably be more
chatty in those soon, too!

Please don't hesitate to reach out to me via IRC or email.
