Also, we now disable confirmation to exercise a verifier mismatch. An
upcoming implementation change can probably detect the mismatch too
early otherwise, and throw WrongPasswordError before the test can
compare the verifiers.
This allows the Wormhole setup path to be simpler: consistently doing a
claim() just before watch(), regardless of whether we allocated the
channelid (with get_code), or dictated it (with set_code or
from_serialized).
The websocket lives on a Resource of the main rendezvous web site, and
the websocket URL is derived from the main "relay_url", so there's no
extra port to allocate, and no extra service to shut down.
Use 'autobahn[twisted]' just to be sure (plain 'autobahn' worked fine
for py27, but maybe it's needed for py35 or something).
Autobahn is failing to do some conditional import and accidentally
depends upon pytrie (for some encrypted WAMP thing) when we didn't ask
for it (https://github.com/crossbario/autobahn-python/issues/604). This
commit also adds a manual dependency on pytrie (which is pretty small)
until the upstream bug is fixed.
Deliver not-yet-JSONed objects to listeners (both in broadcast_message
and as the "catch-up" responses to add_listener). Also make the (web)
frontend responsible for adding "sent" timestamps. This all makes
rendezvous.py less web-centric.
The core Wormhole exchange will retain a blocking/non-Twisted
implementation, but the file-transferring Transit class is going to be
Twisted-only (maybe Twisted+asyncio). I want to improve the
protocol (add more parallelism, reduce round-trips), and the blocking
implementation is a messy bundle of threads and ick.
When this process is done (eventually), I'll be splitting out the
blocking Wormhole class into a separate distribution, which doesn't
depend upon Twisted.
