Julien Vermillard commented on ASYNCWEB-11:
-------------------------------------------
After some debugging, look like the problem in in the state machine codec
(ConsumeToEndOfSessionDecodingState), I'm going to open a MINA specific issue
for that
> HttpResponseDecoder not finishing decode process before some content is
> received
> --------------------------------------------------------------------------------
>
> Key: ASYNCWEB-11
> URL: https://issues.apache.org/jira/browse/ASYNCWEB-11
> Project: Asyncweb
> Issue Type: Bug
> Components: Common
> Environment: FCGIHttpService
> Reporter: Daniel Wirtz
> Priority: Trivial
>
> Basically I transform FastCGI responses into HTTP responses using the
> HttpResponseDecoder in conjunction with AsyncFCGI (0.9.0 CVS):
> public void onReceive(FCGIRequest request, FCGIResponse response) {
> HttpServiceContext context = (HttpServiceContext) request.getAttachment();
> HttpResponseDecoder decoder = new HttpResponseDecoder();
> DecoderOutput output = new DecoderOutput(context); // Custom output
> implementing a write() method
> decoder.decode(null, IoBuffer.wrap("HTTP/1.1 200 OK\r\n".getBytes()),
> output);
> decoder.decode(null, response.getStdout(), output);
> decoder.finishDecode(null, output); // HttpResonse is produced and sent to
> DecoderOutput
> decoder.dispose(null);
> }
> This works fine so far, but when an empty response (in this case produced by
> PHP is received), no write() to DecoderOutput occurs even though the
> finishDecode() method was called. The response looks like this:
> Content-Type: text/html\r\n
> \r\n
> As a result of this, I'm not able to use the decoder in this particular case
> to produce HttpResponse objects for further asyncweb processing originating
> from a FastCGI backend. The connection just times out because no response is
> produced. However, if Content-Length: 0 is provided, it works fine (but PHP
> does not produce this header by default, it is added by the webserver, in
> this case this would be asyncweb).
> The reason that I don't want to preparse the output by myself is that this
> results in unneccessary double checking (converting the IoBuffer to something
> parseable and checking headers twice).
