Subject [jira] Commented: (HARMONY-3018) [drlvm][unit] cunit test thread/test_ti_instrum.c fails from time to time
Date Thu, 22 Feb 2007 07:04:05 GMT

    [ https://issues.apache.org/jira/browse/HARMONY-3018?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12474927

Elena Semukhina commented on HARMONY-3018:


1) I changed the signs in condition just because I'd like to express unambiguity: it seems
to me that the number of the threads should decrease through iterations so "!='  could not
be "<".

2) You are right: it should be (cycles < 0);

3) 10 min is a huge time in the context of the test but it should guarantee that we really
meet a bug bit not a delay :)

>      [echo] ERROR: Test failed: Wrong number waiting on monitor threads (/export/lab_drlbuild/combined_gcc/CVS_20070117_0002_H/drlvm/trunk/vm/tests/unit/thread/test_ti_instrum.c:139)
> To run the test iteratively please use the following command:
>  i=0; while true; do ./test_ti_instrum -Dorg.apache.harmony.vm.vmdir=$DRLVM_HOME/bin/default
-Djava.home=$DRLVM_HOME; ec=$?; echo $i $ec; test $ec != 0 && break; i=$[i+1]; done
> Once I saw the failure on linux ia32 icc debug build.
