Handling multiple user contexts

Hi,

I was wondering how to add a user context to something like

Async.each(users, (user, callback) => {

	Sentry.configureScope((scope) => {

		scope.setUser(user);
    });

	// Do something async for the user
	// capture error for user in/after that async function
	// Resulting user context will be the last user
}, callback);

I’ve tried creating a specific hub but that had the same issue

const userSpecificHub = new Sentry.Hub(Sentry.getCurrentHub().getClient());
userSpecificHub.run(() => {/* above example code here */})

Trying to do userSpecificHub.configureScope to set the user resulted in the second hub/scope to have no user context.

I’m probably doing something wrong but I’m trying to add some context to some background processes (most of them get started by https://github.com/kelektiv/node-cron/)

Do you have access to the user throughout the whole life-span of that async function and you capture errors manually? Or do you want to rely on integrations?

If former, then it should be:

const users = [
  { id: 0 },
  { id: 1 },
  { id: 2 },
  { id: 3 },
  { id: 4 },
  { id: 5 },
  { id: 6 }
];

const processUser = user => {
  return new Promise((resolve, reject) => {
    setTimeout(() => {
      if (user.id % 2 === 0) {
        Sentry.withScope(scope => {
          scope.setUser(user);
          Sentry.captureException(new Error("whoops"));
        });
      }
      resolve();
    }, Math.random() * 1000);
  });
};

Promise.all(users.map(processUser)).then(() => {
  console.log("done");
});

However, if you want to have a separate hub for a whole life-span and modify it in various places, then this will work:

const users = [
  { id: 0 },
  { id: 1 },
  { id: 2 },
  { id: 3 },
  { id: 4 },
  { id: 5 },
  { id: 6 }
];

const processUser = user => {
  return new Promise((resolve, reject) => {
    const hub = new Sentry.Hub(Sentry.getCurrentHub().getClient());
    hub.configureScope(scope => scope.setUser(user));

    setTimeout(() => {
      if (user.id % 2 === 0) {
        hub.captureException(new Error("whoops"));
      }
      resolve();
    }, Math.random() * 1000);
  });
};

Promise.all(users.map(processUser)).then(() => {
  console.log("done");
});

Closing as this seems to be solved.
