• Subsystem: HTTP2

Code sample:

const http2 = require('http2')
const server = http2.createServer()
server.on('stream', (stream, headers) => {
  stream.pushStream({ ':path': '/test' }, (err, pushStream) => {
    if (err) throw err
    pushStream.end('pushed some data')
  })
  stream.end('some data')
})
server.listen(8080, () => {
  let client = http2.connect('http://localhost:8080')
  let req = client.request({ ':path': '/' })
  req.on('data', (data) => {
    console.log(data.toString('utf8'))
  })
  client.on('stream', (pushedStream) => {
    console.log('on stream')
    pushedStream.on('aborted', () => {
      console.log('aborted')
    })
    pushedStream.on('end', () => {
      console.log('end')
    })
    pushedStream.on('data', (data) => {
      console.log(data.toString('utf8'))
    })
  })
})

Output:

on stream
some data
pushed some data
end
aborted

Expectation:

aborted event is not fired
