I would appreciate people's advice about how to track down a hang in
the Junit tests. I have added a new test case to
TableFunctionTest. When I execute the test standalone, it runs
fine. When I execute the surrounding suite, everything succeeds
also. However, when I run the full set of junit tests, the run hangs
in a later suite. I tried increasing the memory given to the testrun,
but this does not fix the problem. I would appreciate:
1) advice about how to instrument the test run so that I know which
test case I'm hanging in
A thread dump could possibly help, and it would show if there are any
Java level deadlocks. Either do a kill -QUIT on the Java process, or use
the jstack utility bundled with the JDK (I'm assuming that you're still
using JDK 1.5 on Mac?).
2) random theories which may occur to you
stress.multi hung in many runs last week because of a deadlock between
TableDescriptorOIDCache and TableDescriptorNameCache. Should be fixed
now, though. A thread dump would tell whether that's the problem.
Thanks, Knut. Increasing the max PermGen size got the tests past the
out-of-memory-error. They then hung on test case 8515 out of 8520, in
org.apache.derbyTesting.functionTests.tests.replicationTests.ReplicationRun_Local_StateTest_part1.
I interrupted the tests with "kill -quit" as you recommended. I'm
attaching the console output.

runswingjunittests is a script which sets up the classpath and then
runs the swing runner with this command:
java -Xmx512m -XX:MaxPermSize=128M
-DderbyTesting.oldReleasePath=/Users/rh161140/derby/upgradeReleases
junit.swingui.TestRunner -noloadin
(Without the -XX:MaxPermSize switch, the tests would stop with an
out-of-memory error, running out of PermGen space.)
Once the swing runner is brought up, I run the master script:
org.apache.derbyTesting.functionTests.suites.All
Here's the console output:

At this point the tests are hung on test case 8515 out of 8520, running
org.apache.derbyTesting.functionTests.tests.replicationTests.ReplicationRun_Local_StateTest_part1.
I attempted to kill the test process with "kill -quit". This produced the
following dump:
