Memory Leaks Suck
-
Purify is a good tool, but I'm not able to use it anytime when the application becomes complex. I've got one where Purify sysematically crashes :)

I had something similar but I reported the problem to Rational and they soon fixed the problem. In fact, I have nothing but praise for Rational Tech Support.

Black Cat wrote: Even if the leaks reported are true, they can be in third-party software which you can't touch This can be a good thing. I have a printing app that is susceptible to leaks in printer drivers, and I have used Purify logs to prove this to a certain printer manufacturer. Not only did this get my customer off my back, but the manufacturer actually fixed the leak (eventually). Personally I find Purify indispensable. Tools like this and BoundsChecker will easily pay for themselves in the long run.

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.

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

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.

At least with C++ we know where the memory leaks are!

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! I'm turning into a grapefruit!

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!
