There was some vestigal server-cli code (leftover in the client-side
wormhole.cli.cli_args) that used port 3000/3001, and it accidentally got
used for the new Click-based parser, rather than the actual server-cli
code (in wormhole.server.cli_args) that uses port 4000/4001. This
changes the port numbers to match (everything uses 4000/4001 these days,
to avoid confusing interactions with the old 0.7.6 server that might
still be listening on the old ports).
With increased usage, I'm seeing a buildup of stale channels. Since the
channels aren't properly ephemeral yet (where they get closed as soon as
the last subscriber disconnects), clients which terminate without
calling close() tend to leave the channel lying around. We don't have
"persistent wormholes" yet, so channels should be much more ephemeral
than they currently are.
The reasoning is that this string is only ever likely to refer to the
version of the primary/initial client (the CLI application, written in
Python, that you get with "pip install magic-wormhole"). When there are
other implementations, with unrelated versions, they should obviously
not pay attention to a warning about the other implementation being out
of date.
This will be useful for the upcoming "persistent wormhole" mode. A
client might send an allocation request, crash/terminate before
receiving a response, then restart, then re-send the request. If the
server sees a request with the same request_id a previous request, it
can return the same nameplate.
We'll need code changes on both sides to support this (nothing sends or
checks request_id yet), but this lands the schema change early to reduce
future disruption.
* add "released" ack-response for "release" command, to sync w.close()
* move websocket URL to root
* relayurl= should now be a "ws://" URL
* many tests pass (except for test_twisted, which will be removed, and
test_scripts)
* still moving integration tests from test_twisted to
test_wormhole.Wormholes
This made sense for ServerSentEvent channels (which has no purpose once
the channel was gone), but not so much for websockets. And it prevented
testing duplicate-close.
Pass in a handle and a pair of functions, rather than an object with two
well-known methods. This should make it easier to subscribe to multiple
channels in the future.
