StringOrArray.MarshalJSON emits JSON null for a nil slice (see existing test "nil slice marshals as null" in TestStringOrArrayMarshalJSON), but UnmarshalJSON did not have a matching case for null and fell to the default branch, returning "invalid string_or_array value: <nil>". A round trip of a nil slice therefore failed. This bit the rpcclient against btcd's own getblockchaininfo, whose Warnings field is a StringOrArray that the server leaves as a nil slice when there are no warnings. Every rpctest integration test that touches GetBlockChainInfo (TestBIP0009, TestBIP0068AndBIP0112Activation, TestBIP0113Activation, TestPrune) failed to decode the response. Handle the nil case explicitly so null decodes back to a nil slice, and add regression cases for "warnings: null" and an omitted warnings field to TestGetBlockChainInfoWarnings. |

btcjson
Package btcjson implements concrete types for marshalling to and from the bitcoin JSON-RPC API. A comprehensive suite of tests is provided to ensure proper functionality.
Although this package was primarily written for the btcsuite, it has intentionally been designed so it can be used as a standalone package for any projects needing to marshal to and from bitcoin JSON-RPC requests and responses.
Note that although it's possible to use this package directly to implement an RPC client, it is not recommended since it is only intended as an infrastructure package. Instead, RPC clients should use the btcrpcclient package which provides a full blown RPC client with many features such as automatic connection management, websocket support, automatic notification re-registration on reconnect, and conversion from the raw underlying RPC types (strings, floats, ints, etc) to higher-level types with many nice and useful properties.

GPG Verification Key
All official release tags are signed by Conformal so users can ensure the code has not been tampered with and is coming from the btcsuite developers. To verify the signature perform the following:
-
Download the public key from the Conformal website at https://opensource.conformal.com/GIT-GPG-KEY-conformal.txt
-
Import the public key into your GPG keyring:
gpg --import GIT-GPG-KEY-conformal.txt -
Verify the release tag with the following command where
TAG_NAMEis a placeholder for the specific tag:git tag -v TAG_NAME
