Commit Message: [http1 codec] Allow HTTP/1 requests/responses with Transfer-Encoding and Content-Length headers set.
Additional Description: opt-in for serving requests/responses with Content-Length and Transfer-Encoding: chunked. Per RFC remove Content-Length header before forwarding it to upstream.
Update http-parser version to include fix for nodejs/http-parser#517.
Risk Level: Medium
Testing: unit tests, update integration test
Docs Changes: updated docs/root/version_history/current.rst
Release Notes: http: added allow_chunked_length configuration option for HTTP/1 codec to allow processing requests with both Content-Length and Transfer-Encoding: chunked. If enabled - per RFC Content-Length is removed before sending to upstream.

Fixes #11398

Cool, thanks for tackling this - I'm sure someone else down the line is going to have traffic which hits this unusual corner case.

Thanks, this LGTM. Will give @PiotrSikora @htuch some more time to take a look again if they want. @antoniovicente is out till Monday so all things being equal I would prefer to wait for him to get back to take a final look. cc @asraa also for the H1 codec error handling changes.

Looks good from my end - just two minor nits.

Looked at changes since my last set of comments. Thanks for adding tests for the response cases.

+              !(parser_.flags & F_CHUNKED))) {


Out of curiosity: what coverage do we have for 1xx responses that include content-length or transfer-encoding: chunked headers?

When would this PR get into envoyproxy/envoy-wasm so that istio can pick it up? We are actually hitting this edge case. @alyssawilk

alyssawilk · 2020-09-21T13:19:58Z

Up to folks on that side.
Did @jplevyak 's last merge sort this out for you? Looks like it landed the same day you pinged here.

ceastman-ibm · 2020-09-21T13:36:37Z

@alyssawilk we won't be able to test this until this version of envoyproxy gets into istio and then into our IBM managed istio offering.
