Hi all,
I had problems with some unit tests related to concurrency of the KiWi
Triplestore on mac. As the first build failed I made around 20
additional builds with diver gating results. I also wiped the local
repository twice to simulate several clean builds:
On every first build I got an error in the AfterClass of the H2
concurrency Test (kiwi-triplestore module).
org.apache.marmotta.kiwi.test.H2ConcurrencyTest Time elapsed:
3.64 sec <<< FAILURE!
java.lang.AssertionError: null
[..]
at
org.apache.marmotta.kiwi.test.H2ConcurrencyTest.dropDatabase(H2ConcurrencyTest.java:63)
Follow up builds (with -rf :kiwi-triplestore) have never shown this.
New build sometimes do. Looks like if this is somehow related on how
much Disc IO was done in-between two tests ...
I also randomly got failures that do look like they where all related
to concurrency (kiwi-triplestore module) (in –20% of the tests)
testPreparedTupleQuery2(org.apache.marmotta.kiwi.test.sesame.repository.KiWiRepositoryConnectionTest)
Time elapsed: 0.011 sec <<< FAILURE!
java.lang.AssertionError: unexpected value for name: "Alice"
expected:<"Bob"> but was:<"Alice">

org.junit.internal.runners.statements.FailOnTimeout$StatementThread.run(FailOnTimeout.java:74)
There was also (once) an issue in the reasoner - could be also related
to concurrency as AFAIK the reasoning is also done in an own thread
testResolveBaseTriplesMulti(org.apache.marmotta.kiwi.reasoner.test.engine.JustificationResolutionTest)
Time elapsed: 0.216 sec <<< FAILURE!
java.lang.AssertionError: expected:<2> but was:<4>

org.apache.marmotta.kiwi.reasoner.test.engine.JustificationResolutionTest.testResolveBaseTriplesMulti(JustificationResolutionTest.java:190)
Finally two times I got what seams to be a deadlock of some sort in
the org.apache.marmotta.platform.core.test.config.ConfigurationServiceTest
Thread qtp614303200-48 - /marmotta/resource/YR6ENRVc is waiting on
an active Exclusive lock acquired in qtp614303200-48 -

This exception was repeated every some minutes. I both cases I stopped
the process after ~10min.
