Subject [jira] Reopened: (HTTPCORE-45) Pipelined requests cause HttpException
Date Mon, 19 Mar 2007 19:43:32 GMT

     [ https://issues.apache.org/jira/browse/HTTPCORE-45?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Steffen Pingel reopened HTTPCORE-45:
------------------------------------


While running tests I found a case where pipelined requests are not being handled:

1. Send two pipelined requests that are read into DefaultNHttpServerConnection.inbuf
2. Suspend input and process first request 
3. Request input

Since the second request has already been read into a buffer, consumeInput() is never invoked
again and the request is not processed.

> I have a simple server implementation that uses DefaultServerIOEventDispatch and BufferingHttpServiceHandler.
Pipelined requests can cause an exception when DefaultNHttpServerConnection receives another
request while still processing the response to a previous request:
> org.apache.http.HttpException: Response already submitted
> 	at org.apache.http.impl.nio.DefaultNHttpServerConnection.submitResponse(DefaultNHttpServerConnection.java:162)
> 	at org.apache.http.nio.protocol.BufferingHttpServiceHandler.commitResponse(BufferingHttpServiceHandler.java:369)
> 	at org.apache.http.nio.protocol.BufferingHttpServiceHandler.processRequest(BufferingHttpServiceHandler.java:358)
> 	at org.apache.http.nio.protocol.BufferingHttpServiceHandler.requestReceived(BufferingHttpServiceHandler.java:167)
> 	at org.apache.http.impl.nio.DefaultNHttpServerConnection.consumeInput(DefaultNHttpServerConnection.java:97)
> 	at org.apache.http.impl.nio.DefaultServerIOEventDispatch.inputReady(DefaultServerIOEventDispatch.java:77)
> [...]
