[hibernate-dev] Analyzing the ORM testsuite

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: 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
