Hi all,
I'm trying to analyze the memory usage of current master of Hibernate
ORM; I started looking because of OOM errors on the PostgreSQL
testsuite (as mentioned in another thread).
So far I've seen that Mockito is allocating a "lot of stuff"; I might
be able to improve some things in that area but it's a distraction
from my goal as clearly we use Mockito even when not running the
PostgreSQL backed tests and that seems to run fine. But it's polluting
the data reports so making it hard (and slow!) to verify if there is a
real issue.
I could use some help to verify some tangential issues though; when
running the testsuite locally it's taking much longer than what I've
been used to see for the same testsuite some weeks ago, and I have
some failures - regularly seeing the same failures.
These are triggered by running a default build, on H2:
> Task :hibernate-core:test
org.hibernate.test.criteria.CriteriaLockingTest >
testSetLockModeDifferentFromNONELogAWarnMessageWhenTheDialectUseFollowOnLockingIsTrue
FAILED
org.junit.runners.model.TestTimedOutException
org.hibernate.test.criteria.CriteriaLockingTest >
testSetLockModeNONEDoNotLogAWarnMessageWhenTheDialectUseFollowOnLockingIsTrue
FAILED
java.lang.Exception
org.hibernate.test.criteria.CriteriaLockingTest >
org.hibernate.test.criteria.CriteriaLockingTest FAILED
java.lang.Exception
org.hibernate.test.locking.warning.LockNoneWarmingTest >
org.hibernate.test.locking.warning.LockNoneWarmingTest FAILED
java.lang.Exception
6307 tests completed, 4 failed, 327 skipped
Yet the puzzling point: on ci.hibernate.org I don't see these failures
happening, nor the testsuite time seems to have increased of any
significant amount (it regularly completes in somewhere between 15 and
20 minutes). It takes me more than an hour to get this result on a
machine which would normally complete the testsuite in 8 minutes, and
I got the same 4 failures when re-running it a second time.
Could other developers also please checkout master - specifically at
commit 291d4a3eeaa2ade32a42cfbcad5868b2114c34fe - and let me know if
it works allright for you and if the build time is consistent with the
usual times for your machine? I need to understand what might be
different between my workstation and the CI server.
I might even have some great improvements ready to reduce the
testsuite time, but I'm not comfortable in committing them in this
context.
Thanks,
Sanne
