Bump mongodb from 2.2.33 to 3.2.7

[dependabot]

Bumps mongodb from 2.2.33 to 3.2.7.

Release notes

Sourced from mongodb's releases.

v3.2.1

The MongoDB Node.js team is pleased to announce version 3.2.1 of the driver.

Due to a publishing snafu v3.2.1 was immediately published without a proper v3.2.0 release

The Topology class no longer uses a callback store, instead relying on a server selection loop for operation execution. This means failed operations will fail faster, with more accurate stack traces and specifics about the failure. It generally makes it much easier to reason about what the driver is doing each time an operation is executed.

You can enable it with the useUnifiedTopology feature flag passed to your MongoClient constructor, like so:

const client = MongoClient('mongodb://localhost:27017', { useUnifiedTopology: true });

This topology layer will replace the existing topologies in a breaking 4.x release later this year, so we strongly encourage our users to try it out as soon as possible.

A call to withTransaction begins a new transaction, executes the provided function, and then attempts to commit the transaction. The function passed to withTransaction must take a session parameter, and this session must be passed to all methods within the function. If some error is encountered, it will attempt to re-commit the transaction before ultimately failing back to the user after aborting the transaction. NOTE: A mentioned, the passed in function MAY be retried multiple times, please keep this in mind when executing non-database operations within the function.

Here’s an example of it in action:

const client = new MongoClient();
await client.connect();
const session = client.startSession();
// NOTE: the withTransaction method only supports functions that return a Promise
try {
await session.withTransaction(async function(session) {
const coll = client.db('foo').collection('coll');
await coll.insertOne({ a: 42 }, { session });
});
} catch (err) {
// transaction failed after attempted retry
console.dir({ err });
}
