Apple's stock python doesn't use GNU libreadline, instead it uses BSD
libedit with a readline compatibility interface. The syntax to enable
tab completion is different for libedit. By including both bindings,
autocomplete should work on both flavors.
Closes#37. Thanks to @wsanchez for the catch and the fix.
(one displayed message per received welcome["motd"])
There's not much value in prohibiting the server from sending multiple
MOTD messages, and it would prevent us from using it to display a "your
client is using an old API, please upgrade" message after having already
sent a regular "please donate" MOTD message. (We could send a second
welcome message with ["error"] to kill the client, but ["motd"] is the
most convenient way to deliver a non-fatal warning).
This is an alias for the same host, so it's not really an incompatible
change. The new hostname is my personal domain, and seems a bit more
suitable for this service.
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not pay attention to a warning about the other implementation being out
of date.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 gives us room in the future to put other keys there, like one which
says we want to use Noise for the phase-message encryption instead of
our current HKDF scheme.
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.
This will allow a future peer to figure out what transit modes we can
and cannot do, and thus avoid spinning up expensive modes that we won't
be able to use (e.g. WebRTC).
The new autobahn release removes the Twisted pin, so we no longer need
one. Depend on the new autobahn to flush out any environments that are
still using the old one (and thus can't use the current Twisted).
Thanks https://github.com/crossbario/autobahn-python/issues/680 !
This enhances the ACK that wormhole-receive returns when it finishes
receiving all the data to be a dictionary. The dict includes the SHA256
hash of everything it received, and the sender checks this for a match
before declaring the transfer to be a success. This guards against data
being shuffled somehow during transit.
