Load cpu 100% macOS

[klerick]

Environment details

• OS: MacOs Mojave
• Node.js version: 8.12.0 and 10
• npm version: 10.5.0 and 6.1.0
• @google-cloud/pubsub version: 0.22.0 and 0.23.0

I am having a problem with a pubsub sdk.
I've tried to reproduced it on other pc and have got the same result.
If I try to run a subscribe script, I will get cpu loading on 100%
If i use linux, it will work ok.

const { PubSub } = require('@google-cloud/pubsub');
const pubsub = new PubSub({
  credentials: {}
});
const subscription = pubsub.subscription(topicName);
subscription.on(`message`, message => {
  console.log(`Received message ${message.id}:`);
  console.log(`\tData: ${message.data}`);
  console.log(`\tAttributes: ${message.attributes}`);
  messageCount += 1;
  message.ack();
});

Hi @klerick I'm having a bit of trouble reproducing this, could you provide me with a little bit more info?

• Are you using GCLOUD_PROJECT env var?
• Are you using default application credentials?
• Roughly how many messages are pending before creating a subscription?

I've tried to use GOOGLE_APPLICATION_CREDENTIALS env var, and everything works fine. But if I create PubSub object using params. A, then I get load 100% cpu and I do not get any error message.

@klerick I just made a release (0.24.0) that should resolve the issue you're seeing. If you continue to encounter this issue, please let us know! Thanks again for the report!

@callmehiphop I've checked a new version. As I see the problem is still there

@callmehiphop let me know if you want to talk about caching the promise on GoogleAuth.getClient.

@JustinBeckwith I'd love to!

@klerick I made a branch with a possible fix, would you be willing to test it out for me?

So I think I've narrowed this down to an auth issue (googleapis/google-auth-library-nodejs#614), although I'm waiting on a response of some kind, I think the fix for this will be small and hopefully coming soon.

@klerick good news, I think this has been fixed in the latest google-auth release. Its a minor change so we won't be releasing a new version of PubSub, but you might need to reinstall to pick up the latest auth changes.

I'm going to close this (again), but if your issue persists please let me know! Thanks again!
