Memory Leaks Suck

I remember myself involved in a project with multi-threaded DCOM server. Weeks spent on memory leak fixes. Yes, eventually all leaks were resolved, but was it creative work? I was like a detective hunting for a murderer. Yeah, that was fun in some way, but at that time I was not adding new features to our product, not getting new ideas. I am more and more on .NET now, and what a boost in efficiency! Вагиф Абилов MCP (Visual C++) Oslo, Norway Hex is for sissies. Real men use binary.

Too good to be useful? Don't be silly. They have saved me tons of time. Also, if the memory leak is in a 3rd party application you can't touch, then, well YOU CAN'T TOUCH IT. But at least you know have proof it is in that 3rd party software. Tim Smith I'm going to patent thought. I have yet to see any prior art.

Now, comparing the following two options: 1. Write a C++ app that has a lot of memory leaks, and then buy a tool like Purify to find the leaks and plug them. 2. Write a .NET app that is impossible to have a memory leak. Nah, only an idiot will choose 2, it's too damn easy! ;P

A decent shared pointer class can prevent weeks of pain and anguish, try boost::shared_ptr and keep your nassty C#. Cyclic IUnknown::AddRef()'s, now they really suck. Ryan
They read good books, and quote, but never learn a language other than the scream of rocket-burn. Our straighter talk is drowned but ironclad; elections, money, empire, oil and Dad.

You're right. It wasn't an HP. It was a Lexmark. HP printer drivers are notoriously leaky, and HP support couldn't give a damn. Their idea of testing a printer driver is to print a couple of pages from Word, and if nothing crashes then the driver passes. When the HP4050 first came out back in 1998 it included a driver that leaked ~1MB every 100 pages printed which caused me and my company a whole load of sh*t.

Or 1. Write a well-written C++ app, and handle memory yourself, so you know exactly what it's doing 2. Write a .NET app and just hide in a corner and pretend the memory issue doesn't exist at all -- Help me! I'm turning into a grapefruit!

OK, I'll explain myself. VB - You gotta be kidding me. I actually have to tell you *why* I wouldn't use VB? No, I didn't mean VB. I'm with about this one :) Java - Because of javascript. I didn't mean Java either. .NET - Microsoft proprietary bullshit. I wouldn't write a "managed" C++ app on a bet (unless it involves my current employment). Can you say "VB wrapped in C++"? No, I don't think C# has anything with VB wrapped in C++. The more I work with C#, the more I'm convinced with its elegancy and efficiency. And they're even working on generics! I've been using STL for some time but still am not able to declare map iterator without syntax error at first attempt. Yes, .NET comes with non-deterministic memory management, but as soon I realized it was managing it well, I let it do it for me. Вагиф Абилов MCP (Visual C++) Oslo, Norway Hex is for sissies.

I have no argument with people who have so much confidence in them. But don't forget, Mr. Tim Smith isn't so confident, he would rather trust Purify to find all the leaks.

That's just silly. Which would you trust more: Developer one who says "Yes, my code hasn't got any memory leaks. I know because I'm a good programmer, and I wouldn't make mistakes like that" or Developer two who says "Yes, my code hasn't got any memory leaks, because I rigourously tested it with a wide range of tools" -- Help me!

That's not anything like what he said, nor even implied. He said he uses Purify to find memory leaks that would otherwise may well have taken him days to locate on his own. That's not a lack of confidence, that's using the right tool for the right job.

"Having no memory leak at all" or "Having no memory leak visible, hoping the OS will clean" ? ;P When an application becomes more complex than "Hello Word", Garbage collectors suck !

Looks like I can just call Server.Redirect("Mr. Tim Smith") and let you two C++ programmers talk it over. ;)
What is there to discuss - I'm just agreeing with him that using extra tools to help bulletproof your software and remove bugs is a good thing, rather than a sign of a bad programmer. Ok, in an ideal world programmers would write code that worked flawlessly first time, but we know that that isn't going to happen -- Help me! I'm turning into a grapefruit!

That's not a lack of confidence, that's using the right tool for the right job. So you agree that C++ alone is not the right tool, and you have to add things like Purify when there are too many hard to track memory leaks. However, as soon as I mention .NET your eyes are turning red like a texas bull. No one is saying .NET is perfect here, if you calm down and read things carefully. .NET, VB, C++, and Java are just tools to me, and I choose them according to the job at hand. So there you go, we may be in complete agreement. ;) John Simmons / outlaw programmer wrote: Stop saying stupid shit... You have been providing some of the most entertaining posts to CodeProject, but I am really disappointed this time, the staggering layers of stupidty in your statement make it a work of art on so many levels. Do I get the honor of being quoted in your signature? Please, please! ;P

Nope, you can have memory leaks in all of those as well. In fact, I just recently saw a vendor's demo for a spiffy diagnostic tool used to locate and fix memory leaks in Java. GC is useful, but it's not a silver bullet, and the sooner people realize that the better. William E. Kempf
