This commit modifies the SearchRawTransactions and
SearchRawTransactionsVerbose functions to work properly with the latest
searchrawtransactions API in btcd.
In particular, this involves changing the return value from
[]*btcjson.TxRawResult to []*btcjson.SearchRawTransactionResult and
adding the additional optional parameter which specifies whether or not
to include information about the previous outputs.
This commit contains several changes needed to update the client to use
the latest version of btcjson. In addition, it contains a couple of other
minor changes along the way.
While the underlying changes are quite large, the public API of this
package is still the same, so caller should generally not have to update
their code due to that. However, the underlying btcjson package API has
changed significantly. Since this package hides the vast majority of that
from callers, it should not afffect them very much. However, one area in
particular to watch out for is that the old btcjson.Error is now
btcjson.RPCError, so any callers doing any type assertions there will need
to update.
The following is a summary of the changes:
- The underlying btcjson significantly changed how commands work, so the
internals of this package have been reworked to be based off of requests
instead of the now non-existant btcjson.Cmd interface
- Update all call sites of btcjson.New<Foo>Cmd since they can no longer
error or take varargs
- The ids for each request are part of the request now instead of the
command to match the new btcjson model and are strict uint64s so type
assertions are no longer needed (slightly improved efficiency)
- Remove the old temporary workaround for the getbalance command with an
account of "*" since btcwallet has since been fixed
- Change all instances of JSONToAmount to btcutil.NewAmount since that
function was removed in favor of btcutil.Amount
- Change all btcws invocations to btcjson since they have been combined
There are certain RPCs where an address should be sent as the raw string
instead of the encoded bitcoin address since the RPC handler on the other
end expects "keys" instead of Bitcoin addresses.
For example, the multisignature RPCs addmultisigaddress and createmultisig
can work with pubkeys (compressed, uncompressed, or hybrid) as well as
Bitcoin addresses.
The original issue which prompted these changes was report by Paul Snow on
IRC.
Rather than using bytes.NewBuffer, which is a read/write entity
(io.ReadWriter), use bytes.NewReader which is only a read entitiy
(io.Reader). Benchmarking shows it's slightly faster and it's also
technically more accurate since it ensures the data is read-only.
There are several RPCs which accept a pointer to a hash, transaction,
block, etc. Previously not all RPCs handled being passed a nil pointer
consistently.
Closes#4.
