[jira] [Commented] (THRIFT-3048) NodeJS decoding of I64 is
inconsistent across protocols
[ https://issues.apache.org/jira/browse/THRIFT-3048?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14371521#comment-14371521 ]
Randy Abernethy commented on THRIFT-3048:
-----------------------------------------
Thanks for the bug report. This is a problem. While it would be nice to have all protos return a number here (as happens in other languages) I think the JavaScript bin/json protos have chosen the lesser of two evils (returning an Int64 object rather than a Number which can't store all possible i64 values).
Patches welcome.

>
> Key: THRIFT-3048
> URL: https://issues.apache.org/jira/browse/THRIFT-3048
> Project: Thrift
> Issue Type: Bug
> Components: Node.js - Library
> Affects Versions: 0.9.2, 1.0
> Reporter: Will Demaine
>
> The NodeJS libraries decode i64 differently between protocols. The {{TCompactProtocol}} returns a {{number}} whereas {{TBinaryProtocol}} and {{TJSONProtocol}} return an {{object}}
> Compact: https://github.com/apache/thrift/blob/master/lib/nodejs/lib/thrift/compact_protocol.js#L815
> Binary: https://github.com/apache/thrift/blob/master/lib/nodejs/lib/thrift/binary_protocol.js#L273
> JSON:
> https://github.com/apache/thrift/blob/master/lib/nodejs/lib/thrift/json_protocol.js#L664
> This leads to a lack interoperability when switching between protocols:
> {code}
> service BTest {
> bool testMethod (
> 1: string protocol
> 2: i64 int64
> );
> }
> {code}
> {code:JavaScript}
> var handlers = {
> testMethod: function(desc, int64, callback) {
> console.log(util.format('%s: %d, %s', desc, int64, typeof int64));
> callback(null, true);
> }
> };
> var startServer = function(callback){
> var serverOptions = {
> services: {
> '/thrift': {
> handler: handlers,
> processor: BTest,
> protocol: thrift.TCompactProtocol,
> transport: thrift.TBufferedTransport
> },
> '/thrift.binary': {
> handler: handlers,
> processor: BTest,
> protocol: thrift.TBinaryProtocol,
> transport: thrift.TBufferedTransport
> }
> }
> };
> this.server = thrift.createWebServer(serverOptions);
> this.server.listen(9887, function serverCreated(){
> callback();
> }.bind(this));
> };
> {code}
> Client side:
> {code:JavaScript}
> compactClient.testMethod('compact small', 123);
> binaryClient.testMethod('binary small', 456);
> compactClient.testMethod('compact', 4294967297);
> binaryClient.testMethod('binary', 4294967297);
> compactClient.testMethod('compact large', 3.602879702e16);
> binaryClient.testMethod('binary large', 3.602879702e16);
> {code}
> Results (0.9.2 and 1.0-dev):
> {code}
> compact small: 123, number
> binary small: 456, object
> compact: 4294967297, number
> binary: 4294967297, object
> binary large: Infinity, object
> {code}
