  • Introducing the FreeBSD Test Suite

    I joined the FreeBSD committer ranks a couple of months ago with the intention to equip FreeBSD with an out-of-the-box test suite and with a testing infrastructure. The time until now has been quite fruitful and I have been rushing to get something ready for you before the year end. With that, I am very pleased to announce that the first mockup of the FreeBSD testing cluster is up and running!

  • Header files: Poor compilation times in C++

    Have you ever wondered why building C++ code is so awfully slow and, apparently, compilation times haven’t gotten any better over the course of many years? Wonder no more. This article on C++ Compilation Speed published on August 17, 2010 on Dr. Dobb’s delves into the problem. Mind you, a major cause of such slowdowns are header files and the fact that they are a horrible replacement for a modules system.

  • Header files: Qualify your identifiers

    Apologies for the long pause in the header files series and in blogging in general. With the holidays in between and, especially, with my refreshed energy to do stuff in the FreeBSD and Kyua camps, I haven’t had any reasonable amount of time to write. And, sincerely, with my very limited free time I really cannot cover it all. So… these days, coding it is thus expect a reduced blogging pace!

  • Header files: Poor man's replacement for modules

    I don’t like header files and, especially, I don’t like having to use them to implement modules. When you have used a language that sports real modules—pretty much anything other than C or sh—, header files feel primitive. Well, they actually are primitive. But what do I mean by “real modules”? Modules! In a language that supports modules, a module is a collection of related data types and code exposed via a well-defined set of symbols encapsulated in a single container (name).

  • lutok-0.3, kyua-testers-0.2 and kyua-cli-0.8

    Yesterday was release day: I pushed out Lutok 0.3, Kyua Testers 0.2 and Kyua CLI 0.8. There are not a lot of changes in these new releases. The reason I cut them was to publish the new TAP-compliant tester and make it available for use in FreeBSD as soon as possible. I will be using this new feature as part of the FreeBSD Test Suite in order to hook existing test programs without having to rewrite them to use the ATF libraries (or at least not as a first step).

  • Header files: Avoid C++ 'using' directives

    Following up on the previous C++ post, here comes one more thing to consider when writing header files in this language. using and using namespace The C++ using directive and its more generic using namespace counterpart, allow the programmer to bring a given symbol or all the symbols in a namespace, respectively, into the calling scope. This feature exists to simplify typing and, to some extent, to make the code more readable.

  • Header files: C++ ipp files

    Hoping you had a nice holiday break, it is now the time to resume our series on header files with a new topic covering the world of template definitions in C++. If you have ever used the Boost libraries, you may have noticed that aside from the regular hpp header files, they also provide a bunch of accompanying ipp files. ipp files, in the general case, are used to provide the implementation for a template class defined in a corresponding hpp file.
