Subject [jira] Updated: (DERBY-577) Test harness should not change the user.dir property , it is meant for infomative purpose only.
Date Wed, 10 May 2006 07:27:05 GMT
     [ http://issues.apache.org/jira/browse/DERBY-577?page=all ]

Myrna van Lunteren updated DERBY-577:

    Attachment: DERBY-577_102_20060509.stat

Attached patch - DERBY-577_102_20060509.* - removes the testJvmProps.addElement("user.dir="+userDirName);
line from RunTest, as well as some additional lines that set user.dir.
As a result of this change, 2 tests failed - store/Beetle6038.java and tools/dblook_test.java
(and derbynet/dblook_test_net.java which extends the tools one). With the change, these tests
would pass when run with RunTest, but fail in a suite. 
I found that instead of relying on getCanonicalPath() for these tests, I had to use a full
path obtained by accessing derby.system.home - property - hence the changes to dblook_test.java
and Beetle6038.java.

derbyall passes with this change except for:
 - wisconsin (looks like the known intermittent different optimizer choice)
- SuicideOfStreaming (known current failure)
- runtimeinfo (which fails intermittently in this 1 environment but passes elsewhere for me)

> If  the  user.dir property is changed ,  you wil  find IO calls are working on different
directory than what is returned  by 
> File.getAbsolutePath()   if the file handle is created with a relative path  because
of JVM issue: 4117557 http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4117557
> I think  it  is  not good  idea for test harness to change  the user.dir property.  
 It makes hard to debug tests ,  because 
> files  are not created  at  diferent location than  what is returned by getAbsolutePath().
   Atleast,   I had  fun time figuring out this :-)
> user.dir  is being  changed at the following code segment :
> org.apache.derbyTesting.functionTests.harness. RunTest.java 
>  testJvmProps.addElement("user.dir="+userDirName);
