[durran]

What is changing?

• Updates hasAtomicUpdates to throw when all updates are undefined and ignoreUndefined is true.
• Updates all operations that leverage atomic updates to pass through the bson options.
• Adds both unit tests and new integration tests.

Is there new documentation needed for these changes?

None

What is the motivation for this change?

NODE-6638

Release Highlight

Update operations will now throw if ignoreUndefined is true and all operations are undefined.

When using any of the following operations they will now throw if all atomic operations in the update are undefined and the ignoreUndefined option is true. This is to avoid accidental replacement of the entire document with an empty document. Examples of this scenario:

import { MongoClient } from 'mongodb';

const client = new MongoClient(process.env.MONGODB_URI);

client.bulkWrite(
  [
    {
      name: 'updateMany',
      namespace: 'foo.bar',
      filter: { age: { $lte: 5 } },
      update: { $set: undefined, $unset: undefined }
    }
  ],
  { ignoreUndefined: true }
);

const collection = client.db('test').collection('test');

collection.bulkWrite(
  [
    {
      updateMany: {
        filter: { age: { $lte: 5 } },
        update: { $set: undefined, $unset: undefined }
      }
    }
  ],
  { ignoreUndefined: true }
);

collection.findOneAndUpdate(
  { a: 1 },
  { $set: undefined, $unset: undefined },
  { ignoreUndefined: true }
);

collection.updateOne({ a: 1 }, { $set: undefined, $unset: undefined }, { ignoreUndefined: true });

collection.updateMany({ a: 1 }, { $set: undefined, $unset: undefined }, { ignoreUndefined: true });
