liuyang created BOOKKEEPER-408:
----------------------------------
Summary: BookieReadWriteTest will enter the endless loop and will
not leave out
Key: BOOKKEEPER-408
URL: https://issues.apache.org/jira/browse/BOOKKEEPER-408
Project: Bookkeeper
Issue Type: Bug
Components: bookkeeper-server
Affects Versions: 4.1.0
Environment: SUSE System
ZooKeeper server
three BookKeepers
Reporter: liuyang
When I run the tests of BookKeeper, I found that the test running forever and
cannot be finished. The log has the exception that is
"junit.framework.AssertionFailedError: Return code is not OK: -6".
I thought this issuse might be come from the synchronization mechanism used by
the BookieReadWriteTest.
for example in BookieReadWriteTest.TestReadWriteAsyncSingleClient()
1. when called the function lh.asyncAddEntry(entry.array(), this ,sync), the
call back function is addComplete(int, LedgerHandle, long, Object)
2. we can see that in addComplete(..) the function will be fail when rc !=
BKException.Code.OK, and the x.counter++ will not be called never.
3. we assume that the function addComplete(..) is fail. so, in
TestReadWriteAsyncSingleClient(), the while loop enter endless loop because
sync.counter < numEntriesToWrite is right forever.
