----------------------------
Summary:
TestAppendOnlyStreamWriter#testPositionUpdatesOnlyAfterWriteCompletionWithoutFsync
failed occasionally
Key: DL-171
URL: https://issues.apache.org/jira/browse/DL-171
Project: DistributedLog
Issue Type: Bug
Components: tests
Affects Versions: 0.4.0
Reporter: Liang Xie
Assignee: Liang Xie
I had seen several failed running, i.g. the latest one:
https://builds.apache.org/job/distributedlog-precommit-pullrequest/68/com.twitter$distributedlog-core/testReport/com.twitter.distributedlog/TestAppendOnlyStreamWriter/testPositionUpdatesOnlyAfterWriteCompletionWithoutFsync/
I can reproduce it after several runnings locally, after diving into the
detail, it turn out that an execution sequence issue: once the "writer.write"
be done, if "writer.position()" be invoked easier than the
WriteCompleteListener onSuccess callback, due to the "synchronized", the
position result will be 0, not the expected 33. we can just add a short sleep
to avoid this test issue.
