I'm trying to reproduce this bug in PBXT:

https://bugs.launchpad.net/pbxt/+bug/668491

Great!

I use sources from mariadb-5.1.42.tar.gz

That's quite an old version, you should use the latest.

I got some problems trying to run maria's test suite. What I want is to run the pbxt.preload test. I can confirm that PBXT engine is compiled-in. I tried several ways like

./mysql-test-run pbxt.preload ./mysql-test-run --do-test=pbxt.preload ./mysql-test-run --start-from=pbxt.preload

but every of them failed with some kind of init error... Any ideas of a quick-fix?

Using source tarball should work, but I would recommend using the bzr tree. Here is a step-by-step instruction that works for me: bzr branch -rtag:mariadb-5.1.53 lp:maria/5.1 work-5.1-bug66849 cd work-5.1-bug668491/ BUILD/compile-pentium64-valgrind-max (cd mysql-test && ./mtr pbxt.preload) Note, however, that this failure is hard to re-produce. Usually when the test is run, it succeeds. Only occasionally on the heavily loaded buildbot machines does it fail. Here is a search against the database of past failures for this test: http://buildbot.askmonty.org/buildbot/reports/cross_reference#branch=5.1&revision=&platform=&dt=&bbnum=&typ=&info=&fail_name=pbxt.preload&fail_variant=&fail_info_short=&fail_info_full=&limit=100 As you can see, the failure is quite rare, only a few failures out of the hundreds of test runs our Buildbot does each day. But according to the bug report, I was able to repeat as follows: (cd mysql-test && for i in `seq 1 1000` ; do ./mtr --parallel=3 pbxt.preload pbxt.preload pbxt.preload || exit 1 ; done) I just tried it, and I was able to reproduce with above loop, however it takes several minutes to see the failure. (I'm using 64-bit Ubuntu 8.04 on a 2.4 GHz Core 2 Duo laptop). Good luck, and let me know if you need more help. - Kristian.
