Subject [jira] [Commented] (THRIFT-4437) JS WebSocket client callbacks invoked twice on parallel requests
Date Thu, 28 Dec 2017 10:23:00 GMT

Philip Frank commented on THRIFT-4437:
--------------------------------------

This issue would have been caught by the `ThriftWS` test suite, which is not enabled for some
reason. I will add a commit to my PR that enables these tests.

>             Project: Thrift
>          Issue Type: Bug
>          Components: JavaScript - Library
>    Affects Versions: 0.11.0
>            Reporter: Philip Frank

> When using a WebSocket Transport and doing two service calls immediately, without waiting
for the first to return, e.g. like this:
> {code:javascript}
> const t = new Thrift.TWebSocketTransport('ws://localhost:8338/hello');
> 	const p = new Thrift.TJSONProtocol(t);
> 	const client = new HelloSvcClient(p);
> 	t.open();
> 	client.test(function (res) {
> 		console.log(1, res);
> 	});
> 	client.test(function (res) {
> 		console.log(2, res);
> 	});
> {code}
> The callback to the first invocation is called twice, and the second never, i.e. console
shows:
> {code}
> 1 "test result"
> 1 "test result"
> {code}
> instead of the expected
> {code}
> 1 "test result"
> 2 "test result"
> {code}
> I suspect this bug was introduced with the patch for https://issues.apache.org/jira/browse/THRIFT-4131
where for some reason the callback registered twice when set: https://github.com/apache/thrift/pull/1372/files
