[jira] [Updated] (HTTPCORE-345) Resource leak in
EntityAsyncContentProducer when produceContent is never called
[ https://issues.apache.org/jira/browse/HTTPCORE-345?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Tad Whitenight updated HTTPCORE-345:
------------------------------------
Attachment: EntityAsyncContentProducer.diff
TestHttpAsyncPrematureTermination.diff
TestHttpAsyncPrematureTermination.diff adds a check for closing of the underlying entity in the existing integration tests.
EntityAsyncContentProducer.diff is the aforementioned possible fix: consume the entity if the channel was never created.

> Key: HTTPCORE-345
> URL: https://issues.apache.org/jira/browse/HTTPCORE-345
> Project: HttpComponents HttpCore
> Issue Type: Bug
> Components: HttpCore, HttpCore NIO
> Affects Versions: 4.2.4
> Environment: Tested on Sun JDK 6 Linux 64 & Win 32
> Reporter: Tad Whitenight
> Attachments: EntityAsyncContentProducer.diff, TestHttpAsyncPrematureTermination.diff

>
> The HttpAsyncContentProducer javadoc does not mention that the produceContent method must be called.
> However, the close() method of EntityAsyncContentProducer assumes that the produceContent method was previously called.
> Quickly cancelled requests made to an HttpAsyncService can realize this scenario and thus leak resources backing response entities.
> I discovered this issue in 4.2.4, but am currently reproducing the issue with trunk.
> I'll attach a simplified test case shortly.
> A possible fix is to check if the channel was never created and close the underlying entity in this case.
