Key Names Containing '.' Not Supported

[megantinleywilson]

mongojs version: 2.6.0
mongodb version: 3.6.4

Mongojs does not support key names containing '.', even though MongoDB now supports key names containing '.'. (see https://docs.mongodb.com/manual/reference/limits/#Restrictions-on-Field-Names)

var sync = require('synchronize');

var db = mongojs(
  'mongodb://localhost:3001/'
);

sync.fiber(() => {
	const test = sync.await(db.sandbox.insert({
		variables: {
			'test.var' : 'test'
		}
	}, sync.defer())); 
	if (test) console.log(test);
}, (err) => {
	if (err) console.log(err); 
	process.exit();
}); 

When trying to insert a key name containing '.', the error message is as follows:

Error: key test.var must not contain '.'

The bug is actually a bug in mongodb-core @2.1.19. Mongojs requires mongodb which requires mongodb-core. After updating to mongodb-core @3.0.9, inserting key names containing '.' no longer threw an error. Upgrading the dependency mongodb to the latest version would update mongodb-core to the latest version which would fix the problem.

The strange this is: I can create a document with a dot if I set the _id myself, however I cannot create a document when the _id is generated:

Does work:

    db.testcollection.save({"_id": "testdocument", "dot.ted.": "value"}, (err, res) => {
    	console.log(err, res);
    });

Does not work:

    db.testcollection.save({"dot.ted": "value"}, (err, res) => {
    	console.log(err, res);
    });

I first thought dat updating a document with a dot key also worked, but its identifying the dot as a subkey. Maybe this is the reason dots are not implemented?

Any solution for this is still happening in the latest build.
