Dan Pantry

@Mat'sMug gist.github.com/danpantry/3b82e882594b7ed734cda096d697dc3d

Latter is what we have now, former is what I think is probably the better option

Previously DbContext was thread-scoped, which I believe leads to bad practices (for one, it assumes that all connections have their own thread, which for IIS is true but Project Katana is completely false)

...What's happening to me... I'm caring about a strongly typed language.....

Also, first "Cons" in repositoryishpattern should be "Pros".

syb0rg

@CaptainObvious You almost snuck past me

Mat's Mug

Shouldn't DbContext live in request scope?

Dan Pantry

@Mat'sMug I was under the impression DbContext should be created for one unit of work

So, for example, creating an appointment would be a unit of work because it is one transaction

ardaozkal

19:11

< unless my guesses of who will win the elections are correct, I'll be a pony for a month.

Mat's Mug

Didn't look at the gist yet... but I assume you have the DbContext wrapped with a simple IUnitOfWork interface and constructor-injected such that the IoC container controls the context's lifestyle

Dan Pantry

@Mat'sMug uhh.. that's the latter, yes.

and what we have now.

The issue is that falls down when you have something that requires transactional behaviour (like modifying two things at once)

Maybe that's a problem with our current architecture, though.

Mat's Mug

It does assume one transaction per request..

Dan Pantry

@Mat'sMug Yes, but if both service A and service B require a dbcontext, even if they are the same db context, they will both execute SaveChanges at different times, thus B can fail while A succeeds even though it should be in a transaction

Mat's Mug

wait a sec, so you have service A doing thing A and service B doing thing B, and both thing A and thing B need to be in the same transaction?

Dan Pantry

19:21

(Y)

Now you see the problem, which is why I am thinking that our services are doing too much

And that the real solution lies in between the two approaches

sticking with DbContext being injected but moving more stuff to a factory or something

If you look at the gist it will become clear: Our schema is absolute rubbish. Creating an appointment requires creating an entry in the Appointment table but also the Calendar or History table depending on a set of criteria

Modifying the schema would be a good idea but it's not possible now for backwards compatibility reasons

Mat's Mug

why would service A call into service B?

Dan Pantry

Because the way the app is currently architected is such that service B is doing some work and service A is doing some work instead of service A/B not doing any work (and just saving stuff to a DB)

Mat's Mug

        dbContext.Appointments.Add(model);
        dbContext.CalendarEvents.Add(CreateCalendarEventForAppointment(model));
        dbContext.SaveChanges();

this looks right to me

Dan Pantry

Yes, we don't have that.

We have the secnod model

So the real answer is a mix of both sections

Mat's Mug

let the calendar service do its thing, and have the appointment service do its thing - the two are separate things that shouldn't know about each other IMO

Dan Pantry

19:26

I guess this is why they say software is hard. it's easy to write code, it's hard to write good code.

ardaozkal

Dan Pantry

@Mat'sMug Well, creating an appointment necessarily means creating a calendar item... with properties of the appointment. So at the very least, I'd need another "layer" above those services.

They should not have anything to do with each other, but if either fails, the other needs to be rolled back due to the nature of the schema.

Mat's Mug

or, make an overload in the appointment service, like

void Add(DbContext,CalendarEvent)

so the appointment service can call the calendar service and pass the transaction along with its request

Dan Pantry

Feels like a hack, but I don't think I'm getting any clean solutions with this

Mat's Mug

it feels like a hack because it's not constructor injection... but it's dependency injection nonetheless. via a method parameter.

Dan Pantry

19:31

Well, it feels like a hack because what that achieves is code re-use (which is what I'm trying to do) without breaking transactional purity

Maybe a better idea would be to refactor the logic of the Add method (in all but actually interacting with the dbcontext) into a separate class

Mat's Mug

constructor injection is the preferred way of injecting dependencies. it's not the only way to do it

yes

Dan Pantry

@Mat'sMug I agree, it seems my choices are method injection (which feels dirty) or refactoring logic out

Mat's Mug

void Add(CalendarEvent calendarEvent)

Dan Pantry

I feel really uneasy about the current solution simply because it depends on DbContext being thread-local in order to save changes atomically, so anything is better than that

Mat's Mug

^ this one should call Add(_context, calendarEvent)

software is like a work of art: it's never really "done".

...and most of the time it's "beautiful" only when you look at it in a crooked way

You really should use PHP's built-in functions to handle password security. Make sure that you don't escape passwords or use any other cleansing mechanism on them before hashing. Doing so changes the password and causes unnecessary additional coding. — Jay Blanchard 53 secs ago

Dan Pantry

@Mat'sMug I worked out the problem with my architecture

appointment + calendar item shouldn't really be linked, right?

ilke an appointment can exist on it's own

surely, then, either the DB or the client should orchestrate that interaction

I realised that when I realised there was another interaction like that in our app: creating a query could allow you to create your own contact at the time

currently, the service creates the contact for you based on a string (0 | number | string)

really, the client should create that contact and then submit the query

@SergeyA I think it depends on how mired in the dark ages your code reviewer is. It is a known and designed-in feature of shared_ptr, because the deleter is carried with the shared control block. Anyone who does not realise this has no business reviewing code. Furthermore, any modern (i.e. less than 10 years old) compiler will warn when virtual destructors are required but not declared. — Richard Hodges 57 secs ago

@RubberDuck TIL nulling a Collection reference that contains thousands upon thousands of object references apparently does not cause a memory leak.

Just tested both with adding 1024 x New Class1 references in a tight loop, monitoring the EXCEL.EXE process in task manager; it seems the memory leak is a story to scare kids when it's late - nulling the reference does the job. — Mat's Mug 32 mins ago
