Subject [jira] [Updated] (HTTPCORE-296) IdentityDecoder fails to consume as POST request with Content-Length 0 (zero)

Oleg Kalnichevski updated HTTPCORE-296:

    Fix Version/s: 4.2-beta2

An entity enclosing request that does not deliniate its content either with Transfer-Encoding
or Content-Length header is invalid per section 4.1 of the HTTP/1.1 spec. The problem is that
HttpCore attempts to consume the request by using identity codec instead of rejecting it as

> If a client submits a POST with Content-Length 0, the HttpCore framework will fire the
onContentReceived(...) method of the HttpAsyncRequestConsumer once. However, the decoder (passed
as an argument to onContentReceived()) will never enter the "completed" state, because no
bytes will actually be received from the client. However, reaching the "completed" stage of
the decoder is an requirement for the HttpAsyncServiceHandler to finally process the request
(i.e., call the handle(...) method).
> This leads to the (incorrect) behavior that it is impossible to handle a POST request
with Content-Length 0 in HttpCore NIO.
