The bridge transport uses requests.post, which uses socket.getaddrinfo under the hood, which on some OSes (MacOS, Windows) in CPython takes a lock. The enumerate method for the bridge transport can block for 10-30 seconds while waiting for this lock.
- separation between Wallet and key management (Keystore)
- simplification of wallet classes
- remove support for multiple accounts in the same wallet
- add support for OP_RETURN to Trezor plugin
- split multi-accounts wallets for backward compatibility
We're going to want to do a few things differently, such as
device recovery. So move the client code to clientbase.py
and create a per-plugin client.py file for the derived client
class.
Use a shared device manager across USB devices (not yet taken
advantage of by ledger). This reduces USB scans and abstracts
device management cleanly.
We no longer scan at regular intervals in a background thread.
Break out the workflow logic of the install wizard
into a base class. This means reimplementing with
full support in a new GUI is now easy; you just provide
ways to request passwords, show messages etc. The API
is fully documented in the base class.
There are a couple of minor outstanding issues, including that
the old messages shown when recovering a wallet are missing.
I will come back to that. Ledger wallet might be broken.
Other improvements:
The install wizard code is now easy to follow and understand.
Hardware wallets can now be restored without any need for their
accompanying libraries.
Various bits of trustedcoin were broken and have been fixed.
Many plugin hooks can be removed. I have only started on this.
