Factor out a new RpcService.extractPubKeyAsHex method, to take public
keys from the inputs of the raw transactions returned by the RPC client,
when building TxInput objects to incorporate into the DAO state. Enhance
the method to additionally support segwit (P2WPKH & P2SH-P2WPKH) inputs
(but only the first input for backwards compatibility - see code
comment). Also fix a bug when handling non-SIGHASH_ALL input signatures.
This will allow segwit BSQ to be used in proof-of-burn and issuance txs,
which need a public key associated with the tx to establish ownership of
it, when signing messages with a proof-of-burn or staking merit awarded
from a compensation issuance, respectively.
Also add unit tests for the factored-out method and add a missing RawTx
toString() method, to aid debugging the TxInput fields within the
processed block returned by RpcService.
Migrate RpcService over to the new block notification daemon and RPC
client based on jsonrpc4j. Drop in own DTO classes in place of the ones
defined by btcd-cli4j and rename requestBtcBlock & addNewBtcBlockHandler
to requestDtoBlock & addNewDtoBlockHandler respectively.
Also remove now redundant filtering from the logback config and update
grade-witness.
Wrap any exception that occurs during socket IO or within the supplied
BlockListener with a new 'BlockNotificationException'. This brings the
exception handling more in line with that of the old BtcdDaemonImpl and
makes it easier to match them downstream in FullNode.handleError.
Provide a new 'BitcoindDaemon' block notification socket server, to
replace 'com.neemre.btcdcli4j.daemon.BtcdDaemonImpl'. This starts a
single service thread to listen for raw block hashes on localhost port
512*, sent by the specified 'blocknotify' shell/batch script, delegating
to a pool of worker threads to run the supplied BlockListener handler.
Unlike the original BtcdDaemonImpl class, a call to the 'getblock' RPC
method is not made automatically to supply a complete block to the
handler, instead requiring a separate, manual BitcoindClient.getBlock
invocation from within RpcService.
Also provide unit tests using a mock ServerSocket + Socket.
TODO: Use the new Bitcoind(Client|Daemon) implementations in RpcService,
in place of btcdcli4j Btcd(Client|Daemon)Impl & remove the old library.
Create a new 'BitcoindClient' interface and a corresponding builder, to
replace the old 'com.neemre.btcdcli4j.core.client.BtcdClientImpl' class
from the btcdcli4j library. This is instantiated by jsonrpc4j using a
dynamic proxy. It provides only a cut down version of the bitcoind RPC
API, exposing the methods 'getblock', 'getblockcount' & 'getblockhash',
as they are the only ones currently being used by RpcService.
Add corresponding Jackson-annotated DTO classes to model the JSON
structures returned by bitcoind, very similar to the classes provided by
btcdcli4j. Note that we use Double instead of BigDecimal to represent
fractional fields (difficulties + coin amounts in BTC), as they have
more consistent Jackson (de)serialisation and appear to be able to
faithfully round-trip numeric fields produced by bitcoind. Also note
that doubles can faithfully represent any valid decimal BTC amount (that
is, with 8 d.p. of precision) up to 21 million.
For now, keep the old BtcdClientImpl instance used by RpcService in
place, as the btcdcli4j block notification daemon is dependent upon it
and would also need to be replaced.
Also add unit tests for BitcoindClient which test against sample regtest
responses, using a mock HttpURLConnection.
Add 'witness_v1_taproot' script type to the enum and proto.pb, so that
it doesn't cause any problems when Taproot is activated and the new
script type starts showing up in RPC getBlock(..) responses (including
possibly BSQ transactions).
Also change the Java enum order (which shouldn't cause any problems as
the ordinal isn't used directly in hashCode calculations) and add the
missing 'witness_unknown' enum value to pb.proto to bring it in sync.
The price feed service throws PriceRequestExceptions when switching
currencies, log those exceptions as warnings in the server and don't
pass them up to the CLI.
The server impl was there, but it is now needed by the trading
sim scripts (CLI) to get the price from the Bisq server instead
of the feed. (The server does not request prices more than
once a minute.)
This server log output was intended as an aid to api devs, but
is no longer needed after the change to posix-sytle method opts
with self explanatory labels (replacing the ambiguous positional
CLI method opts).
Prevent failure of testConvertClearNode() on some machines, caused by
use of InetAddress.getHostName on the mock peer address. This does a
reverse DNS lookup and potentially returns something other than the
expected "192.168.0.1" string.
Also avoid an unnecessary getHostName() call on the SOCKS5 Tor proxy
InetAddress in WalletConfig, by using an alternative InetSocketAddress
constructor.
Adds all the gRPC server boilerplate, and a simple help service
that serves method help in man page format. Help text is maintained
in text files located in core/src/main/resources/help.
Only some of the method help text files are defined in this
change, more to be added.
