maven build test error and cannot start db in osx

[sj82516]

Env:

osx: 10.12 Apache Maven 3.5.0 java version "1.8.0_131" Java(TM) SE Runtime Environment (build 1.8.0_131-b11) Java HotSpot(TM) 64-Bit Server VM (build 25.131-b11, mixed mode)

What I did:

clone vaillacore@0.2.2 and run mvn package , it threw some error "org.vanilladb.core.storage.tx.concurrency.ConcurrencyTest Time elapsed: 0.179 sec <<< ERROR! java.lang.OutOfMemoryError: unable to create new native thread " then I tried mvn package -Dmaven.test.skip=true It build the target and .jar file.

Run java -classpath core-0.2.2.jar org.vanilladb.core.server.StartUp test It throw Exception in thread "main" java.lang.RuntimeException: cannot access ..... But I check my file dir and the test folder was created under the project folder which path is defined inside the properties file.

What I expected to see:

successfully run mvn package and run vanillacore server.

Thanks for your report. We just found the problem.

Because our BufferPoolConcurrencyTest intends to create 10000 native threads during testing and OSX usually does not allow so many threads for a process, the testing process fails to create new thread and throws an exception.

We will upload a quick patch to fix this soon.

26 should fix your first problem.

@sj82516, could you try it again ?

[sj82516]

it works now. Thanks

[SLMT]

Great ! BTW, does the second problem still exist ?

[sj82516]

Yes it works now. But it seems that I cannot name my db as "test" nor it would throw

>  java -classpath core-0.2.2.jar org.vanilladb.core.server.StartUp test 
.....
recovering existing database
Exception in thread "main" java.lang.NullPointerException

I changed "test" to "test1" then worked.

Thanks, please close this issue.
