I am facing an issue in the deserialization of java generated protobufs from
protobuf_for_node nodejs library.
*Steps to reproduce the problem?*
1. Serialize the proto-buffers using Java and store it as byte string
2. Read the byte string from NodeJS
3. Deserialize the byte String using the Feed.parse() method. Feed is given
with the required schema assigned with the corresponding descriptor file
compiled from the proto files.
*sample code snippet:*
var Schema = require('protobuf').Schema;
var schema = new Schema(fs.readFileSync('example/test_proto.desc'));
var Feed = schema['proto.root1.root2'];
....
datanode.get("key", function(err, reply) {
Buffer.prototype.toByteArray = function () {
return Array.prototype.slice.call(this, 0)
}
console.log(reply);
var buffer = new Buffer(new Buffer(reply).toByteArray()) ;
aFeed = Feed.parse(buffer); << error thrown here..
While attempting to deserialize from the nodejs using Feed.parse() method, I am
facing the following issue
Error: Malformed message

*Environment:*
OS : RHEL 5.4
Protobuf version : 2.5.0
protobuf-for-node : 0.8.6
NodeJS version : v0.10.7
Is anyone having the similar issue ? let me know if I am doing anything
incorrectly here..
Thanks
