.delete() not sufficient for node process to disconnect

[one19]

Environment:

• Operating System version: MacOS 10.13.4
• Environment: Node command line interface
• Firebase SDK version: at least 4.4.0 and beyond
• Firebase Product: database/auth

Issue:

calling .delete() not sufficient for node process to disconnect.

Steps to reproduce:

What I've thought all along was a pretty standard use for a small cli module:

const ref = await firebase.initializeApp({...});
await ref.auth().signInWithEmailAndPassword(...);

const currentStatusObj = await ref
    .database()
    .ref(...current)
    .once('value');

const newKey = await ref
      .database()
      .ref(...log)
      .child('all')
      .push().key;

await firebase
      .database()
      .ref()
      .update({
        ... multiple paths using path/newKey
      });

return ref.delete()

Except ref.delete() doesn't allow the node process to exit. Ever.

I've had to hack around it with a process.exit() callback for a while now. But now I'm 11 messages into a firebase-functions support issue because using the firebase module in an isomorphic way (functions & cli) causes delays of 20 -> 40 seconds if you return early (even on a hot start). I'd love to narrow down the cause, and to see if this crazy hangup issue that Version 3.4.1 says was fixed is the culprit.

And, just to check, I removed the nice function wrappers and ref passing, and firebase still wouldn't exit on a firebase.app().delete(). nor does .goOffline()

Relevant Code:

https://github.com/one19/im-doin (isomorphic firebase interaction module)
https://github.com/one19/im-doin-slack (function environment where it's not invoked via command line)

firebase web sandbox doesn't provide an adequate location for realizing use case of a node environment.

I had a similar issue where node was not terminating. In my case, I had to also call auth().signOut():

const app = firebase.initializeApp(...);

firebase.database().ref()
  .update(...)
  .then(() => firebase.database().goOffline())
  .then(() => firebase.auth().signOut())
  .then(() => app.delete())

ohmygosh i forgot that I had this as an open ticket! You're absolutely right, thanks!
