What steps will reproduce the bug?
Run this program:
const { createServer, connect } = require('http2');
const assert = require('assert');
createServer().on('stream', function (stream) {
stream.respond({
':status': 200,
'Content-Type': 'application/octet-stream'
});
stream.on('end', () => {
stream.end();
stream.session.close();
this.close();
});
stream.resume();
}).listen(7000, () => {
connect('http://localhost:7000', function () {
this.request({
':method': 'POST'
}, {
waitForTrailers: true
}).on('response', function () {
this.end('12345');
this.on('error', err => assert.equal(err.message, 'write after end'));
this.write('6');
}).on('wantTrailers', function () {
this.sendTrailers({});
});
});
});How often does it reproduce? Is there a required condition?
Every time
What is the expected behavior?
Program should exit
What do you see instead?
Program doesn't exit because server stream doesn't get end event.
Additional information
If you remove the write after end (this.write('6')) then the program exits.
Something is stopping the wantTrailers event being emitted and so the client stream never ends.
Note, changing to waitForTrailers: false also makes it exit (server gets end event).
