Don't C++ allow implementation of multiple abstract classes?
|
|

|

Yes, but multiple inheritance comes with its own complexities. I wouldn't recommend it if your goal is to reduce complexity. This is triply true when templates are also involved.

This is the key point. Friends who worked in the gaming industry mostly burned out due to the insane time-to-market "schedules". The entire point was to get the programs working so they could be published, and it didn't matter how programs worked as long as they worked.
Once a version was published, and sometimes before a version was published, it was on to the next version. There was no time to fix the errors of rushed coding unless something conflicted with something else in the next version.
Sure, this happens in other industries, but gaming is IMO the poster child for propagating and maintaining bad code.

That makes total sense to me. I mean, not that it works that way, but that gaming would be the one to do it.
The pressure to market is just overwhelming with games. It's a constant race against competitors, against newer hardware, against major shopping holidays - it's ridiculous.
I don't think there's a way to fix the code without fixing the above.

nah, they cold like hell, get the game released and move on to another job.
I deal with it every day. If I could get chuckleheads to follow the design concept, but no, no one wants to hurt anyone's feelings. I deal with so much $hit code every day, some days I think my head is going to explode.

If I may venture an opinion: sometimes you don’t. Sometimes that complexity reflects what I call “battle-scarred code”. Old code that has seen many battles is rarely clean but it contains that protection against a divide by 0, and can handle that weird situation we encountered 5 years ago and so on.
Really great companies, like Microsoft, might also have someone like Raymond Chen to maintain some kind of oral history project but in most places you just have to find yourself all the good stories hidden inside the code. And the bad ones too.
Anyway, I learned to respect the battle-scarred code.

I can second this.
Although as far Microsoft, having worked there, you're lucky when you can find history on some of their older but very much used components. There are functions used in oleaut32.dll routinely that I swear nobody at microsoft actually knows how they work, or maybe even how to call them properly anymore.

Having worked elsewhere, Microsoft seems like a paragon of software quality. I’m sure the view from inside is different but those who like sausages should not ask what’s inside

Their departments are semi-autonomous. Their quality kind of depends on the department, but in general they follow the same basic practices, some just better than others. When they do it well, they are really good. They do regression, stress testing, they instrument for code coverage. They have bug counts and charts of counts and goals on the hallways outside of developers quarters. They really do put an emphasis on it. It's why I am so not happy with their windows updates. They can do better. Something happened since I left.

COM is probably one of the best understood technologies at Microsoft. Many of the old COM/OLE guys are still around. Although Don Box[^] left two months ago.
The only API that I know of that might have been lost is the DirectUI code. When the team was dissolved apparently some of the source code disappeared. There was like 1 guy in building 88 with some DirectUI header files last I heard.

oleaut32.dll has a few functions for mangling typelibs that nobody uses anymore, but I had to emulate at one point. I never finished that part because nobody at MS could tell me what they did. I even contacted people involved in the Windows OS team when I was on it.

Hmmmm,

I am pretty sure that the mangling is controlled by the interface definition language[^] so you probably should have asked someone on the compiler team instead.
There use to be some non-public MIDL reserved keywords on our internal build tools. I'm not sure if that's still a thing.

The IDL facilities use the typelib facilities i'm talking about. The compiler team did not create oleaut32.dll

No, we are in a grey area here... oleaut32 has it's origins in VB5. I believe it was distributed with the VB5/VB6 runtime prior to Windows XP SP1.
What time frame are you referring to? Was this back when you worked at the company?

It was old by the time I was working on the Windows team in about 2001.
oleaut32 is a system DLL - i could have sworn it predated VB5 because of OLE automation which predates it, but my memory isn't so reliable these days.
oleaut32.dll provides system implementations of things like IDispatch and ITypeLib. It's basically the guts that make Automation work inside of what is now known as ActiveX** but prior to that was simply called OLE (object linking and embedding)
** I'm simplifying a little bit. OLE and ActiveX both exist, and ActiveX was sort of intended as OLE pared down for web downloads at first but then it became the de facto way to develop new components.

I remember some Microsoft blog video some years ago, and cant remember if was talking to him, that essential majority of the .net documentation (at least 2005 - 2015 maybe) was passed through this one person, hence provided great consistency across the documentation.
As to Frostbite, I wonder how much gaming industry project to project rehire cycle has an impact, and the get it out the door.
If you have somthing like World of Warcraft, where new players coming in over the years, then fixing "old" parts are relevant to user support.
Also go read Object-oriented programming is dead. Wait, really? posted in articles the other day, might be relevant to how people thought they needed to program the system over the years vs reality of programming it.

Working on several generations of the same project for 25 years almost I see that there is no straightforward solution for this.
Setting up code standard does not help, code review does not help...
There is no way to 'clean' an old and complex code but to rewrite it from ground up - it will probably cost more in time than the original investment combined over years and will left you with a buggy code to test from zero...

In your situation, I don't think you can push back. I don't think you want to push back. The code base is mature, and tested many, many times. You can't change it from the ground up, if that is what you are thinking; not for Frostbite, I would think.
I think your best bet is to maintain existing code without refactoring too much, and adding new code in a proper, well organized and scalable fashion, the best you can.
Remember, any code you maintain, that has been tested and is working in Production, and you refactor or change it, you have now added potential bugs to it. The less you refactor or change of existing code, the better.
