BREAKING CHANGE: StellarAssetType is renamed to StellarAsset.
The name StellarAssetType is reused for the corresponding enum.
Enums are introduced in several other places. Their values correspond to
allowed values of (previously int) fields so this should not pose a
compatibility problem.
Many fields are now required. We believe that this should not pose a
compatibility problem, because all known interfaces to Stellar signing
actually accept Stellar XDR on input, whose required fields match the
protobuf schema.
* Changes from original PR
* Now that we are rejecting chain_ids of 0, we need to have the tests set the chain_ids to at least 1.
* Ran 'make gen' and uploaded changed files.
* Ran make style_check and fixed reported errors
* Added changelog files
* Reverted changes concerning chain_id 0 being rejected.
* Adds tests for MAX_CHAIN_ID and MAX_CHAIN_ID+1. Also reverts MAX_CHAIN_ID to the previous value.
* Added missing whitespace around arithmetic operator.

There's two udp calls in `UdpTransport._ping()`:
- socket.sendall(b"PINGPING") -> this will be instanteous, AND it will
raise if the receiving side is not listening.
- socket.recv() -> this will wait for SOCKET_TIMEOUT seconds, but only
in case the sendall() succeeded. This means that receiving side exists
and we are now waiting until it's awake enough to respond.
In conclusion, we avoid hammering emulator with PINGPINGs with a timeout
so short we don't see an answer. This should avoid the problem
occasionally seen in CI and described in #1668
API-compatibility with the original one is retained.
Now that we don't need to keep code parity with core, we could do some
changes that make life easier.
All generated classes are now in one file. This makes github diffs more
readable, at the cost of somewhat complicating inspecting individual
classes; however, that is something we shouldn't be doing anyway.
Enums are now implemented as enum.IntEnum.
The original class-level FIELDS member was restored.
Each field is now defined via protobuf.Field, which is easier to work
with in the codec, AND we're not stuffing defaults and flags into the
same field.
Add two new input and four output script types.
Decred ticket purchases consist of a stake submission, op returns, and
change addresses. Although change addresses are allowed by consensus,
they are no longer used in practice and so have been given the
restrictions of a null pubkey and no value. Stake scripts are almost
identical to p2pkh or p2sh except for an extra opcode in front. Inputs
are currently only used in the form of one input three outputs with the
first output, or stake submission, paying to a public key hash, or with
two inputs and five outputs with the stake submission paying to a
multisig script hash. The op returns are directed to the user in the
case of one and the voting service provider and user in the case of two.
One of the sstx commitment for a ticket must pay back to the trezor
wallet. This is checked and an error is thrown if we don't find the
expected public key hash.
Because this adds the ability to create new types of outputs once the
ticket votes, two new input script types are also needed. A successful
vote will lead to a stake generation script that must be spent, and an
unsuccessful vote will lead to a revocation script that must be spent.
If we allowed stake change scripts to have a valid pubkey, that too
would require another op code, but we disallow those for output.
Because we can't pass SignTx anymore because it has required fields and
the caller is not supposed to fill out those.
Instead you can send arbitrary kwargs that match signtx fields.
BREAKING CHANGE: argument `details: SignTx` is no longer accepted.
init_device() should be used to initialize a session. Reuses existing
session if available.
end_session() explicitly closes any existing session and requests a new
one
lock() enables soft-lock
clear_session() is the equivalent of lock() + end_session()
A new function ensure_unlocked() can be used to open a session and
prompt for PIN and passphrase before further operations.
Update protobuf
- Previous transactions don't need to be sent anymore, because fee is
included in the transaction now. Thus transactions_count can be
removed from CardanoSignTx message and the CardanoTxAck and
CardanoTxRequest messages can be removed altogether.
- CardanoTxInputType.type is unused so remove it
Add NULL (None type) serialisation to CBOR
- Transaction metada must either have a valid structure or CBOR NULL
must be used (if metadata is empty) - it can't be simply left out.
Add protocol_magics file
- Just to have a nicer way of representing protocol magics
Update transaction signing
- Previous transactions no longer need to be requested
- Output building is simplified, since fee doesn't need to be calculated
- Remove transaction class since it is no longer needed (only functions
remained)
- Reorder functions so it reads top to bottom
Add protocol magic to byron address on testnet
- This has always been a part of the spec, but it hasn't been
implemented before, because it wasn't really needed.
Update trezorlib
Update tests
- Transaction messages are no longer required
- Expected values are different since tx format changed
- Common values in test cases have been extracted
Remove unused file
- Progress was used when receiving previous transactions
Add CRC check to output address validation
The original wait_layout was unreliable, because there are no guarantees
re order of arrival of the respective events. Still, TT's event handling
is basically deterministic, so as long as the host sent its messages
close enough to each other, the order worked out.
This is no longer the case with the introduction of loop.spawn: TT's
behavior is still deterministic, but now ButtonAck is processed *before*
the corresponding wait_layout, so the waiting side waits forever.
In the new process, the host must first register to receive layout
events, and then receives all of them (so the number of calls to
wait_layout must match the number of layout changes).
DebugLinkWatchLayout message must be version-gated, because of an
unfortunate collection of bugs in previous versions wrt unknown message
handling; and this interests us because upgrade-tests are using
wait_layout feature.
Protobuf encoding now happens in TrezorClient, and transports get encoded blobs
to (chunkify and) send. This is a better design because transports don't need
to know about protobuf.
It also lays groundwork for sending raw bytes feature (#116)
This commit also removes all vestiges of ProtocolV2 which was never used and
will probably need to be redesigned from the ground up anyway. The code is
still ready for protocol flexibility.
