...many ugly C idioms with simpler and more advanced C++...

So, as part of this great refactoring of the CRT, we have done an enormous amount of work to simplify and improve the quality of the code, so that it is easier to add features and fix bugs in the future. We have converted most of the CRT sources to compile as C++, enabling us to replace many ugly C idioms with simpler and more advanced C++ constructs. The publicly callable functions are still declared as C functions, of course (extern "C" in C++), so they can still be called from C. But internally we now take full advantage of the C++ language and its many useful features.

We have eliminated most of the manual resource management in the code through the introduction of several special-purpose smart pointer and handle types. Enormous functions have been split into smaller, maintainable pieces. We have eliminated 75%(2) of the conditional compilation preprocessor directives (#ifdef, #else, etc.) by converting internal implementation details to use C++ features like templates and overloading. We have converted most of the CRT source files to use a common coding style.

Нормално. Щели да пренаписват и системните драйвери на .нет. Такава им е политиката. Ако изчакат още 1-2 години няма да им остане човек дето да разбере грозните "С" идиоми. Ще гледат сорсовете като асм дебъгера на вс6.

The "best" example of this maintainability problem could be found in the old implementation of the printf family of functions. The CRT provides 142 different variations of printf, but most of the behavior is the same for all of the functions, so there are a set of common implementation functions that do the bulk of the work. These common implementation functions were all defined in output.c in the CRT sources(1). This 2,696 line file had 223 conditionally compiled regions of code (#ifdef, #else, etc.), over half of which were in a single 1,400 line function. This file was compiled 12 different ways to generate all of the common implementation functions. Even with the large number of tests that we have for these functions, the code was exceedingly brittle and difficult to modify.

Before this refactoring, the sprintf functions, which write formatted data to a character buffer, were implemented by wrapping the result buffer in a temporary FILE object and then deferring to the equivalent fprintf function. This worked and produced the correct result, but it was exceedingly inefficient. When writing characters to a FILE we need to be careful to handle many cases like buffer exhaustion, end-of-line conversions, and character conversions. When writing characters to a string, we should simply be able to write through and increment the result pointer. After the refactoring, we were easily able to identify this performance problem and, more importantly, fix it. The sprintf functions are now up to 8 times faster than they were in previous releases.

М$ по нещо ми приличат на БСП! Седнали са на стол с тясна дупка, пъхнали са си топките една по една в дупката и сега стават рязко, ама много рязко! Ние ще гледаме сеира.
