Stas Sribnyi created THRIFT-5025:
------------------------------------
Summary: Incomplete promise rejection
Key: THRIFT-5025
URL: https://issues.apache.org/jira/browse/THRIFT-5025
Project: Thrift
Issue Type: Bug
Components: Node.js - Library
Affects Versions: 0.12.0
Reporter: Stas Sribnyi
I have a problem while performing client requests created with Multiplexer and
HttpConnection.
In case of some errors like 'ECONNREFUSED', 'Connection timed out' and some
other errors http_connection *emits an error, but nothing handles it*,
therefore promise does not reject and in fact just hangs, so we have memory
leaks.
Looks like promise can only be rejected only with a call of clientCallback
[https://github.com/apache/thrift/blob/41f47aff7ccc1a093eb5e48250377c1178babeec/lib/nodejs/lib/thrift/http_connection.js#L140]
As far as I did not find any example of such cases (multiplexer+http
connection+node), it is possible that I use it in the wrong way, but from the
source code perspective it looks like a design flaw, could you please take a
look into this issue?
Here is a simplified source code I use:
{code:java}
const multiplexer = new Multiplexer();
const connection = new HttpConnection({
path: '/rpc',
transport: TBufferedTransport,
protocol: TBinaryProtocol,
nodeOptions: {
host: '127.0.0.1',
port: 8989,
},
});
const client = multiplexer.createClient(
'UserClient',
UserClient,
connection
);
try {
const user = await client.registerUser({
// Some props related to user
} as any);
// perform some actions with response
} catch (error) { // this never happens in case of connection issues and some
internal errors of http connection
// log error
}
{code}
