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
[] (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)
}
