-----------------------------------
Summary: Many WAN DUnit tests with off-heap enabled aren't
actually exercising off-heap
Key: GEODE-5725
URL: https://issues.apache.org/jira/browse/GEODE-5725
Project: Geode
Issue Type: Bug
Components: offheap, wan
Reporter: Ryan McMahon
Fix For: 1.8.0
Many of the WAN DUnit tests are run with both off-heap disabled and enabled.
However, there is an optimization in the off-heap implementation where if the
entry value is less than 8-bytes, off-heap is bypassed and the value is put on
the heap. This is due to the value being equal to or less than the size of the
off-heap address that would have been used. It is therefore pointless to use
off-heap if the value itself is less than the size of the address.
In many WAN tests we are using longs as values, which will bypass off-heap in
this way. However, it is expected that off-heap is being exercised. We should
instead use another data type (strings) as values to be sure that the off-heap
feature is actually being exercised.
