          Components: Node.js - Library
    Affects Versions: 0.10.0
            Reporter: TianYI Wen


Create TBufferedTransport by using its receiver funciton. and using TCompactProtocol to communicate. But this object lack of `rstack` and `rpos`. It make app crash.

Is thrift library tested before release?

details:

thrift file
struct CliRoomData
{
	10: i32 roomId
	20: string roomName
	30: i32 masterUserId
	40: map<i32, CliRoomUserData> mapUserData			// key: user id		value: CliRoomUserData
	50: map<i32, CliRoomLevelData> mapLevelData			// key: level id	value: CliRoomLevelData
	60: optional string groupId
}

generated code which crashes the app:

// input haven't property `rstack` and `rpos`
if (input.rstack.length > input.rpos[input.rpos.length -1] + 1) { 
    input.rstack.pop();
}

code about the crash

  const entity = new Protocols[className]() // create the thrift object to read from protocol
    return new Promise((resolve, reject) => {
        const receiver = thrift.TBufferedTransport.receiver((reader) => { // create buffered using library
            const protocol = new thrift.TCompactProtocol(reader)
            entity.read(protocol) // crash the app
            resolve(entity)
        })
        receiver(payload)
    })
