  • Joining the Board of Directors of The NetBSD Foundation

    Dear readers, It is a great pleasure for me to announce that I have just joined the Board of Directors of The NetBSD Foundation. If you are curious about how this all happened, here it goes: as described in the election procedure, someone who I don't know nominated me back in November of 2010 to become part of the new board composition. After the Nomination Committee made their way through the long list of nominees, interviews and deliberation, they proposed a slate for the new members of the board.

  • Kyua: Weekly status report, BSDCan 2011 edition

    I spent past week in Ottawa, Canada, attending the BSDCan 2011 conference. The conference was composed of lots of interesting content and hosted many influential and insightful BSD developers. While the NetBSD presence was very reduced, I could have some valuable talks with both NetBSD and FreeBSD developers. Anyway. As part of BSDCan 2011, I gave a talk titled "Automated testing in NetBSD: past, present and future". The talk focused on explaining what led to the development of ATF in the context of NetBSD, what related technologies exist in NetBSD (rump, anita and dashboards), what ATF's shortcomings are and how Kyua plans to resolve them.

    Unfortunately, no progress whatsoever this week :-( Too busy at work and preparing my upcoming trips. Time to fly to BSDCan 2011 tomorrow.

  • Kyua: Weekly status report

    Unfortunately, I have had no time for coding this week. The only things I could do were:Fixed a few build problems on NetBSD introduced during past week's changes.Built Kyua and ran a few tests on NetBSD/macppc (just for the joy of it).Coding has been eclipsed by the preparation of my presentation for BSDCan 2011; at this point, this has priority over any code changes. I'd argue that preparing the presentation is also part of the project, so some time has been invested ;-)

  • Use explicit conditionals

    In C — or, for that matter, several other languages such as Python or C++ — most native types can be coerced to a boolean type: expressions that deliver integers, pointers or characters are automatically treated as boolean values whenever needed. For example: non-zero integer expression and non-NULL pointers evaluate to true whereas zero or NULL evaluate to false. Many programmers take advantage of this fact by stating their conditionals like this:

  • Kyua: Weekly status report

    Ouch; I'm exhausted. I just finished a multi-hour hacking session to get the implementation of the list subcommand in control. It is now in a very nice user-facing shape, although its code deserves a little bit of house cleaning (coming soon). Anyway, this week's progress: Added the kyuaify.sh script. This little tool takes a test suite (say, NetBSD's /usr/tests directory) and converts all its Atffiles into Kyuafiles. The tool is no sophisticated at all; in fact, it is a pretty simple script that I haven't tested with any other test suites so far.

  • Kyua: Weekly status report

    This week started easy:Added integration tests for the about and help subcommands. These were pretty easy to do.Added integration tests for the list subcommand. I initially added these tests as expected failures to reason about the appearance and behavior of this command from the point of view of the user before actually working on the code... and I am still writing such code to make these tests pass!This is where things got a bit awry.
