  • Kyua 0.1 released!

    Dear readers, I'm very proud to announce that the very first release of Kyua, obviously numbered 0.1, has been published! The release page for kyua-cli-0.1 contains more details about what this release offers, and don't hesitate to join the kyua-discuss mailing list and ask if you have questions. Kyua was started sometime in past October and it has taken over six months to get the first public version. (It is true that my free time has heavily fluctuated during this period though, so it does not mean that six months of intensive coding have gone into the release ;-) Kyua 0.

  • Kyua: Weekly status report

    A couple of things have happened: Released ATF 0.14. This release was followed by an import into NetBSD and fixing of subsequent fallout.Some performance improvements to atf-sh. After killing a bunch of complex shell constructions and removing lots of obsolete functions, the performance results are significant. There is still room for improvement of course, and I still need to quantify how these optimizations behave in single-core machines.I certainly expected more progress this past week.

  • Validating format strings in custom C functions

    In C, particularly due to the lack of dynamic strings, it's common to pass format strings around together with a variable set of arguments. A prototype like this is very common: void my_printf(const char*, ...); For the standard printf and similar functions, some compilers will ensure that the variable list of arguments matches the positional parameters in the format string and, if they don't match, raise a warning.  This is, however, just a warning "

    Added support for recursion from the top-level Kyuafile. This Kyuafile should not reference any directories explicitly because the directories at the top level are supposed to be created by the installation of packages. Closed issue 9.Improved error messages when the test programs are bogus. Closed issue 13.Backported format-printf attribute improvements from NetBSD head to ATF.Miscellaneous build and run fixes for both Kyua and ATF in NetBSD and OS X.Cut a release candidate for atf-0.

    Some long-standing bug fixes / improvements have gone in this week: Improvements to the cleanup routine, which is used to destroy the work directory of a test case after the test case has terminated:Heavy refactoring to be tolerant to failures. These failures may arise when a child of the test case does not exit immediately and holds temporary files in the work directory open for longer than expected.Any file systems that the test case leaves mounted within the work directory will now be unmounted, just as the ATF test interface mandates.

    Some cool stuff this week, albeit not large-scale: Implemented the --variable flag in the test command. This flag, which can be specified multiple times, allows a user to override any configuration variable (be it a built-in or a test-suite variable) from the command line. This is actually the same as atf-run's -v flag, but with a clear separation between built-in configuration settings and test-suite specific settings.Added support for several environment variables to allow users (and tests) to override built-in paths.

  • Kyua: Weekly status report

    This week:Cleaned up the internal code of the "list" command and added a few unit tests.Added integration tests for the "test" command that focus mostly on the behavior of the "test" command itself. There is still a need for full integration tests that validate the execution of the test cases themselves and their cleanup, and these will be tricky to write.Changed atf-c, atf-c++ and atf-sh to show a warning when a test program is run by hand.
