public class H5BugFixTest
extends TestCase

TestCase for bug fixes.

This class tests all the public methods in H5CompoundDS class.

The test file contains the following objects.

setUp

protected void setUp()
              throws java.lang.Exception

Throws:

java.lang.Exception

tearDown

protected void tearDown()
                 throws java.lang.Exception

Throws:

java.lang.Exception

testBug847

public final void testBug847()
                      throws java.lang.Exception

The following program fails because dataset.init() does not reset the selection of dataspace.

The bug appears on hdf-java 2.4 beta04 or earlier version. It is fixed at later version.

          1)  read the table cell (using dataset selection to select only that row of the table)
          2)  re-initialize the Dataset
          3)  call 'Dataset.clearData()'
          4)  call 'Dataset.getData()'
          5)  change the correct column/row **
          6)  call 'Dataset.write()'
          7)  close the file
          8)  reopen the file and read the table cell as in step 1
          9)  assert that the value has been changed and is correct
          This sequence of actions works correctly on the hdf-java library built for
          64-bit solaris that we received in August 2006.  On the latest (beta-d), This
          fails when attempting to change the value of the 1st and 4th rows (however, it
          works for the 0th row).
 

Throws:

java.lang.Exception

testBug863

public final void testBug863()
                      throws java.lang.Exception

The following operation causes memory leak because a group is left open at file.get().

The bug appears on hdf-java 2.4 beta05 or earlier version. It is fixed at later version.

        while (true)
        {
            H5File file = new H5File(H5TestFile.NAME_FILE_H5, H5File.READ);
            //file.open();
            file.get("/Table0");
            file.get("/Group0");   

            int n = H5.H5Fget_obj_count(file.getFID(), HDF5Constants.H5F_OBJ_ALL);
            if (n>1)
                System.out.println("*** Possible memory leak!!!");

            file.close();
        }
 

Throws:

java.lang.Exception
