Transaction lock in MongoDB

QUESTION

Transaction lock in MongoDB

Asked 2018-Sep-19 at 09:38

I am trying to develop a booking system, that books different assets after checking its availability. The system first tries to read records from the DB and checks if the slot being booked is available. If so, the system books the slot for them by inserting a new record into the system.

Now the problem is, if there are multiple users requesting booking, and since multiple requests to the db can interleave, it will be possible for this scenario to occur.

There are no transaction support in the MongoDB before 4.0 version. For using transactions in 4.0 have a look on https://www.mongodb.com/transactions

In versions above 4.0 you can use findOneAndUpdate method to emulate it.

For example, you can do the modify query as this:

Right now when your code is transpiled to JavaScript it will simple return the result of await this.userService.updateUser(req.body).

You will need to create a new instance of UserResponse from the datavariable. Explicitly setting all the fields you want to set in your instance of UserResponse. Then you have to return that instance of UserResponse instead of data variable.

QUESTION

Mocha ignores some tests although they should be run

Asked 2017-Sep-01 at 19:37

I'm correctly working on refactoring my clone of the express-decorator NPM package. This includes refactoring the unit tests that were previously done using AVA. I decided to rewrite them using Mocha and Chai because I like the way they define tests a lot more.

So, what is my issue? Take a look at this code (I broke it down to illustrate the problem):

It looks like you are moving from tape or some similar test runner to Mocha. You're going to need to significantly change your approach because Mocha works significantly differently.

tape and similar runners don't need to know ahead of time what tests exist in the suite. They discover tests as they go along executing your test code, and a test can contain another test. Mocha on the other hand requires that the entire suite be discoverable before running any test.* It needs to know each and every test that will exist in your suite. It has some disadvantages in that you cannot add tests while the Mocha is running the test. You could not have a before hook for instance do a query from a database and from that create tests. You'd have instead to perform the query before the suite has started. However, this way of doing things also has some advantages. You can use the --grep option to select only a subset of tests and Mocha will do it without any trouble. You can also use it.only to select a single test without trouble. Last I checked, tape and its siblings have trouble doing this.

So the reason your Mocha code is not working is because you are creating a test after Mocha has started running the tests. Mocha won't right out crash on you but when you do this, the behavior you get is undefined. I've seen cases where Mocha would ignore the new test, and I've seen cases where it executed it in an unexpected order.

If this were my test what I'd do is:
