Josh Rickmar 2731634dda Implement notifications that actually follow the JSON-RPC spec.
This changes notifications to JSON-RPC Requests, rather than
Responses, that also satisify the btcjson.Cmd interface and are
registered with btcjson's parser.  This prevents issues where JSON-RPC
Response IDs clash due to a client using the same ID as what an old
notification used.

As this changes the API, and thus, requires notification handlers to
be modified, the remaining missing notifications used by btcwallet
have been implemented.  Applications parsing these notifications, such
as btcgui, can now use a common handler function signature for all
notifications.

Test coverage for all notifications has been added (excluding testing
for badly-marshaled notifications with wrong numbers of parameters, or
wrong types).

Fixes #2.

btcws

[Build Status] (https://travis-ci.org/conformal/btcws)

Package btcws implements extensions to the standard bitcoind JSON-RPC API for the btcd suite of programs (btcd, btcwallet, and btcgui). Importing this package registers all implemented custom requests with btcjson (using btcjson.RegisterCustomCmd).

Sample Use

// Client Side
import (
	"code.google.com/p/go.net/websocket"
	"github.com/conformal/btcws"
)

// Create rescan command.
id := 0
addrs := map[string]struct{}{
	"17XhEvq9Nahdj7Xe1nv6oRe1tEmaHUuynH": struct{},
}
cmd, err := btcws.NewRescanCmd(id, 270000, addrs)

// Set up a handler for a reply with id 0.
AddReplyHandler(id, func(reply map[string]interface{}) {
	// Deal with reply.
})

// JSON marshal and send rescan request to websocket connection.
websocket.JSON.Send(btcdWSConn, cmd)


// Server Side
import (
	"code.google.com/p/go.net/websocket"
	"github.com/conformal/btcjson"
	"github.com/conformal/btcws"
)

// Get marshaled request.
var b []byte
err := websocket.Message.Receive(clientWSConn, &b)

// Parse marshaled command.
cmd, err := btcjson.ParseMarshaledCmd(b)

// If this is a rescan command, handle and reply.
rcmd, ok := cmd.(*btcws.RescanCmd)
if ok {
	// Do stuff
	var reply []byte
	err := websocket.Message.Send(clientWSConn, reply)
}

$ go get github.com/conformal/btcws

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 Conformal. 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_NAME is a placeholder for the specific tag:

    git tag -v TAG_NAME
