Adds behavior similar to the retries of persistent RPC connections
to HTTP request.
* Initial backoff: 500ms
* Linear increase
* Max retries: 10
Room for future improvement:
* Make configurable
* Add jitter
* Tests for retry behavior
* rpcclient: Export sendCmd and response
This facilitates using custom commands with rpcclient.
See https://github.com/btcsuite/btcd/issues/1083
* rpcclient: Export receiveFuture
This facilitates using custom commands with rpcclient.
See https://github.com/btcsuite/btcd/issues/1083
* rpcclient: Add customcommand example
* rpcclient: remove "Namecoin" from customcommand readme heading
Adds interface for issuing a signrawtransactionwithwallet command.
Note that this does not add functionality for the btcd rpc server
itself, it simply assumes that the RPC client has this ability and gives
an API for interacting with the RPC client.
rpc: add signrawtransactionwithwallet interface
* GetBlockTemplate RPC client implementation
* Txid added to the getblocktemplate result
* Omitempty for TxID and improved comment for GetBlockTemplate 'rules' field
Without this, users of this library wouldn't be able to issue GetBlock
requests to nodes which haven't updated to support the latest request
format, namely the use of a single `int` parameter to denote verbosity
instead of two `bool`s.
This change makes btcd's getblock command match bitcoind's. Previously
the default verbosity was 0, which caused errors when using the
rpcclient library to connect to a bitcoind node - getblock would
unmarshall incorrectly since it didn't expect a verbosity=1 result when
it did not specify verbosity.
Refactor GetBlockVerboseResult into two separate types: one type for getblock "hash" verbosity=1,
and a second type for getblock "hash" verbosity=2. This is necessary due to how getblock returns
a block's transaction data based on the provided verbosity parameter.
If verbosity=1, then getblock.Tx is an array of a block's transaction ids (txids) as strings.
If verbosity=2, then getblock.Tx is an array of raw transaction data.
Due to differences in how getblock returns data based on the provided verbosity parameter, it's necessary
to have two separate return types based on verbosity. This necessitates a separate unmarshalling function
(represented throughout rpcclient/chain.go as Result.Receive()) to ensure that data is correctly unmarshalled
and returned to the user.
