BIP0022 defines optional fields in a getblocktemplate request for long
polling and template tweaking.
In addition, for template tweaking, there are two fields, sigoplimit and
sizelimit, which are atypical in that they are allowed to be either
booleans or numeric. This requires the fields to be represented as
interfaces which means any code making use of the struct will need to use
type assertions or a type switch.
This commit updates GetBlockTemplateCmd accordingly.
ok @jcvernaleo
This reasons for this change follow:
- All instances of the same key should be consistent amongst the commands
and returns
- Output indices can't be negative, so rather than adding more code to
check for a negative after unmarshal, just allow the unmarshal to weed
out negatives
ok @jcvernaleo
This change overrides the cmd return value of custom registered
methods to always return an unparsableCmd if the marshaling as a
JSON-RPC request succeeded, but the request was an invalid structure
for the custom method.
This commit extends the RegisterCustomCmd function to also accept a reply
parser which will be invoked for replies to the custom command via
ReadResultCmd. This allows replies to custom commands to be returned a
concrete structs instead of map[string]interface{}.
ok @jcvernaleo, @jrick
This is no longer required since the RawCmd params now consist of a slice
of raw JSON messages which the registered parser can directly unmarshal.
ok @jcvernaleo
This commit modifies the RawCmd type to use a slice of json.RawMessages so
that unmarshalling each individual parameter can be deferred to the
handler for the command.
This is superior to the old method of using a []interface{} because it
means that each parameter is now unmarshalled into the expected concrete
type directly instead of whatever it happens to be in the JSON. Due to
this, the old behavior where every number was unmarshlled as a float64 and
converted to the appropriate final type, which could lead to odd behavior
when going through marshal/unmarshal cycles, has been eliminated. This
change also means each individual parameter can now be full blown structs
(JSON objects) that marshal and unmarshal themselves which greatly
simplifies complex parameters and removes the need for additional and
error prone code.
This commit contains a lot of changes because every command needed its
MarshalJSON and UnmarshalJSON methods updated to support the new
mechanism. As a part of changing these functions, a new common creation
function for the the RawCmd struct was added to avoid the previous
duplication of the common fields. Also, rather than repeating the method
string in each MarshJSON functon, it makes use of cmd.Method().
Finally, some of the error messages were incorrect and have been corrected
as well as made consistent.
ok @jcvernaleo, @jrick, @owainga
The getwork RPC now only accepts a single optional parameter which, if
present, is a string containing the hex-encoded block data to solve.
Also update the tests for the new correct parameters.
ok @jcvernaleo
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.
Changed TxRawResult to omitempty block info for mempool tx as well as
moved Txid to Vin.TxId from Vin.ScriptSig.Txid (both match bitcoind
output)
Added support for new bitcoind [verbose=true] and added non-standard
optional verboseTx to return TxRawResults intead Txids
