Subject [jira] [Commented] (HTTPCLIENT-1228) HttpGet.abort() / HttpPost.abort() doesn't always abort immediately
Date Fri, 31 Aug 2012 16:40:08 GMT

    [ https://issues.apache.org/jira/browse/HTTPCLIENT-1228?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13446113#comment-13446113

Dennis Ju commented on HTTPCLIENT-1228:

I reformatted the code so it's more legible. Every iteration is creating new instances.

Here's a sample output of what I get on OS X 10.8. The last line "Connect to slow.website.com:80
timed out" shows that the request blocked instead of immediately aborting.

Connection has been shut down
Socket closed

>             Project: HttpComponents HttpClient
>          Issue Type: Bug
>          Components: HttpClient
>    Affects Versions: 4.2.1
>            Reporter: Dennis Ju
>            Priority: Minor
>         Attachments: TestAbort.java
> HttpGet.abort() and HttpPost.abort() don't always abort immediately. It works most of
the time, but occasionally the connection will block until it times out. I noticed this only
happens when I explicitly set a timeout value (HttpConnectionParams.setConnectionTimeout()).
> According to HttpComponent docs, "When an HTTP request is aborted its execution thread
blocked in an I/O operation is guaranteed to unblock by throwing a InterruptedIOException".
> The attached test code should demonstrate the issue. Every once in awhile, you'll get
"Connect to slow.website.com:80 timed out".
> I'm running Mac OS X 10.8 (Java version 1.6.0_29).
