This fixes the breakage introduced by transport reshuffles.
It's still not great and I'd love to see context manager based sessions.
But it's good enough for now.
There is no good reason to do that and it hides situations when
the field mistakenly doesn't exist.
Added comment explains that missing "vendor" field might by caused
by trezor-common mismatch, which fixes#328
- drop set_tx_api method and its usage from trezorctl
- drop _prepare_sign_tx which is not used anymore
- adapt trezorctl to new signing API
- make trezorctl signing smarter, ahead of moving it elsewhere
This also moves DebugLinkMixin to debuglink.py and converts the mixin to
a subclass of TrezorClient (which is finally becoming a
reasonable-looking class). This takes advantage of the new UI protocol
and is ready for further improvements, namely, queuing input for tests
that require swipes.
The ui.py module contains a Click-based implementation of the UI
protocol. Use of callback_* methods has been limited and will probably
be cleaned up further (The contract has changed so we'll try to make
third party code fail noisily. It is unclear whether a backwards
compatible approach will be possible).
Furthermore, device.recovery() now takes a callback as an argument. This
way we can get rid of WordRequest callbacks, which are only used in the
recovery flow.
This clarifies the intent: the project is licenced under terms
of LGPL version 3 only, but the standard headers cover only "3 or later",
so we had to rewrite them.
In the same step, we removed author information from individual files
in favor of "SatoshiLabs and contributors", and include an AUTHORS
file that lists the contributors.
Apologies to those whose names are missing; please contact us if you wish
to add your info to the AUTHORS file.
This removes the --erase option which was fishy before (and is now superseded
by wipe_device in bootloader mode).
Also adds a draft of "local fingerprint check" functionality for T1. This will
be expanded to work with TT in future releases.
