streamed filtering spec

[Stas Bekman]

Doug,

what's the status of the streaming filtering implementation?

We have a semi-working implementation of output filtering, and no input filtering. If I remember correctly we were waiting for Apache API to stabilize, please correct me if I'm wrong. My impressions from talking to people at ApacheCon is that 2.0 API is going to be frozen any moment now and we shouldn't expect any changes to the filtering API. So it's a go sign.

I want to spec out the streaming implementation, complete the missing output filtering features and implement the input filtering.

Current known issues with the input filtering:

- if the stream include EOS, the filter can't send any more data, after the bucket with EOS has been passed through, so we need to do some trickery. My suggested patch is here:
http://marc.theaimsgroup.com/?l=apache-modperl-dev&m=102828686110352&w=2
and awaits comments.

- Esteban Fernandez Stafford noticed another problem

when the data doesn't fit into one bucket brigade and the filter gets it in chunks. We need to spec out how to handle this situation if the filter wants to setaside data because it hasn't received enough data.
