This commit significantly changes the address extraction code. The
original code was written before some of the other newer code was written
and as a result essentially duplicated some of the logic for handling
standard scripts which is used elsewhere in the package.
The following is a summary of what has changed:
- CalcPkScriptAddrHashes, ScriptToAddrHash, and ScriptToAddrHashes have
been replaced by ExtractPkScriptAddresses
- The ScriptType type has been removed in favor of the existing
ScriptClass type
- The new function returns a slice of btcutil.Addresses instead of raw
hashes that the caller then needs to figure out what to do with to
convert them to proper addressses
- The new function makes use of the existing ScriptClass instead of an
nearly duplicate ScriptType
- The new function hooks into the existing infrastructure for parsing
scripts and identifying scripts of standard forms
- The new function only works with pkscripts to match the behavior of the
reference implementation - do note that the redeeming script from a p2sh
script is still considered a pkscript
- The logic combines extraction for all script types instead of using a
separate function for multi-signature transactions
- The new function ignores addresses which are invalid for some reason
such as invalid public keys
This implements --onion (and --onionuser/--onionpass) that enable a
different proxy to be used to connect to .onion addresses. If no main
proxy is supplied then no proxy will be used for non-onion addresses.
Additionally we add --noonion that blocks connection attempts to .onion
addresses entirely (and avoids using tor for proxy dns lookups).
the --tor option has been supersceded and thus removed.
Closes#47
This commit modifies the names of opcdoes shown in the oneline script
disassembly to match the reference implementation. In particular
OP_1NEGATE, and OP_0 through OP_16 are changed to the raw numbers
they represent when doing oneline disassembly. When doing full
disassembly, the full opcode names are still shown.
ok @owainga.
This commit modifies the new valid peer message to display the useragent.
Previously this information was only available by setting the PEER
subsystem debuglevel to debug or lower.
This was prompted by #64.
Rather than returning an empty string from DisasmString if a script fails
to parse, return the disassembly up to the point of the failure along with
[error] appended. The error is still returned in case the caller wants
more information about the script parse failure.
This commit adds two new functions named PayToScriptHashScript and
PayToAddrScript. The first one creates and returns a public-key script
which pays to the provided script hash and conforms to BIP0016.
The second function takes the new btcutil.Address interface type and
returns an appropriate script to pay to the address type in the interface.
It currently works for btcutil.AddressPubKeyHash and
btcutil.AddressScriptHash.
The inputs to the createrawtransaction command are JSON strings, however
the NewCreateRawTransactionCmd function takes concrete types. Thus,
callers which deal with the raw JSON need a method to perform the
validation and conversion. This logic is the same as what needs to happen
when unmashalling a full JSON-RPC command, so this commit factors that
logic out into a separate function and exports it.
Fixed up bad function comment headers
Added a small set of tests for the ScriptToAddrHashes function to test
functionality of a couple real multisig cases as well as error checking
The name handlers for a package level is a bit too generic and could
easily cause a name collision. Even though the compiler would catch it,
use something a bit more descriptive.
Since the command to handler mappings are the most often modified and
referenced code in rpcserver.go and rpcwebsocket.go, move them near the
top of their respective files.
This commit cleans up the standard RPC command hanlding a bit by removing
the websocket specific notification channel from the handlers. This was
previously required because the sendrawtransaction, when called from a
websocket enabled connection, needs to add a notification for when the
transaction is mined.
This commit modifies that to instead implement a websocket extended
version of sendrawtransaction which invokes the standard handler and adds
the notification. In addition, the main send was modified to first look
if the command has a websocket specific handler first, and then falls back
to standard commands, rather than the previous approach of first checking
for a standard command and falling through to websocket commands. This
essentially allows websockets connections to extend commands with the same
name with additional functionality such as what was done in this commit.
The rpcserver.go file is starting to get a bit unwieldy. This commit
moves the separable websocket specific bits into a separate file named
rpcwebsocket.go.
Added MarshalJSON method to Vin which properly omits the Vout field
from coinbase Vin's by using anonymous structs with the proper
subsets of fields outputted by bitcoind
Changed Vout.ScriptPubKey to add omitempty for ReqSigs and Addresses:
both fields are not shown when there is an error identifying to
scriptType or parsing addresses in bitcoind
Added error checking for script disassembley
Changed vout to handle errors in processing the way bitcoind does: the
type displayed is "nonstandard" when the calculated type is nonstandard
or nulltype and also when there is an error getting the address.
Still doesn't properly support multisig addresses, but now it should
return "nonstandard" since since address lookup fails for those cases.
Since the decoderawtransaction result makes use of the same vin and vout
lists, this commit also factors the logic for those out into separate
functions.
