I've set up BUGSLAYERUTIL.DLL to use the DLL versions of the CRT libraries. The two extensions I demonstrate in this chapter, MemDumperValidator and MemStress, are also in BUGSLAYERUTIL.DLL. These extensions expect you to be using the DLL versions. If you want to use the extensions in your application but not the DLL versions, however, it's MEMDUMPERVALIDATOR.CPP, trivial to pull out the source files, MEMDUMPERVALIDATOR.H, MEMSTRESS.CPP, MEMSTRESSCONSTANTS.H, and MEMSTRESS.H; change the function linkage specified; and drop them into your application. I want to mention one additional detail about using BUGSLAYERUTIL.DLL in your projects. You might experience a slowdown in your application depending on how you allocate memory. As part of the MemDumperValidator extension, I turn on all the appropriate flags, including _CRTDBG_CHECK_ALWAYS_DF, in the DCRT library to allow full memory tracking and validation. The _CRTDBG_CHECK_ALWAYS_DF flag tells the DCRT library to walk through and validate each piece of heap memory each time you allocate or deallocate heap memory. If you're doing thousands of small allocations in your application, you'll see the slowdown. This is a perfect indication that you probably need to look at your data algorithms. Doing lots of small allocations is a huge performance problem, so you'll need to fix it. If you can't change the code, you can turn off the flag by calling _CrtSetDbgFlag. Using MemDumperValidator The MemDumperValidator extension makes memory debugging much easier. By default, the DCRT library reports memory leaks and validates that memory blocks haven't experienced overwrite or underwrite corruption. Both those reports can be very useful, but when the memory leak report looks something like the following, it can get difficult to figure out exactly which type of memory leaked: Detected memory leaks Dumping objects -> TestProc.cpp(104) : {596} normal block at 0x008CD5B0, 24 bytes long. Data: < k 8C 00 w k > 90 6B 8C 00 B0 DD 8C 00 00 00 80 77 90 6B

This chapter focuses on the various kinds of methods that you ll run into, including instance constructors and type constructors, as well as how to define methods to overload operators and type conversions (for implicit and explicit casting) . We ll also talk about extension methods, which allow you to logically add your own instance methods to already existing types, and partial methods, which allow you to spread a type s implementation into multiple parts .

Ruby began life in Japan as the creation of Yukihiro Matsumoto, known more commonly as Matz. Unlike that of most language developers, Matz s motivation for Ruby was fun and a principle of least surprise, in order to improve overall developer productivity. He couldn t find a language that resonated with his mindset, so he took his own outlook about how programming should work and created Ruby (named after the gemstone, but a convenient homage to the Perl programming language). A longtime object-oriented programming fan, Matz felt it was the best model to adopt. However, unlike other languages, such as Perl, object orientation with Ruby wouldn t be an afterthought, but act as the core foundation for the whole language. Everything would be an object, and methods would fill the roles of the procedures and functions developers had come to expect in older procedural languages. As Matz himself said in a 2001 interview, I wanted a language that was more powerful than Perl, and more object-oriented than Python. That s why I decided to design my own language. In December 1995, Matz released the first public alpha version of Ruby, and soon thereafter a community began to form in Japan. However, although Ruby quickly became relatively popular in Japan, it struggled to gain a foothold elsewhere.
