http2: Fix "ERR_HTTP2_INVALID_CONNECTION_HEADERS" error when adding "connection' into header #23908

sagitsofan · 2018-10-26T18:46:28Z

lib: http2 compatibility connection header

When adding the connection header into
http2 response, an ERR_HTTP2_INVALID_CONNECTION_HEADERS
error is thrown.

This PR is ignoring the connection header and disable the
ERR_HTTP2_INVALID_CONNECTION_HEADERS error.
A new warning log is emitted on the compatibility.

Fixes: #23748

Checklist

make -j4 test (UNIX), or vcbuild test (Windows) passes
commit message follows commit guidelines

This would change the behavior for non-compat mode also, which is not ideal. The check should be done in compat.js rather than in util.js

lib/internal/http2/util.js

sagitsofan · 2018-10-27T07:57:31Z

Ok.
I will move it into the compatibility API, and update this PR.

apapirovski

This is unfortunately not the right approach. I've left some comments.

What about this PR, it is waiting for approval long time.

dougwilson · 2018-11-30T19:18:22Z

Hi @sagitsofan , I was just a passer by, similar to you and just had a comment; I don't have the ability to move this further along and eventually merge, sorry.

sagitsofan · 2018-12-15T16:16:15Z

@jasnell @mcollina Added test, please review.

mcollina

The test should verify if the warning is emitted.

sagitsofan · 2018-12-15T16:32:18Z

@mcollina, I have verified that the warning is emitted and also i am making sure that adding the connection into the header is not throwing any exception.

LGTM

+  if (name !== constants.HTTP2_HEADER_CONNECTION)
+    return true;
+  else
+    return value === 'trailers';


Nit: this could be simplified to:

return name !== constants.HTTP2_HEADER_CONNECTION || value === 'trailers';

I took the liberty to improve the commit message and addressed my nit while landing.

When using the compatibility API the connection header is from now on ignored instead of throwing an `ERR_HTTP2_INVALID_CONNECTION_HEADERS` error. This logs a warning in such case to notify the user about the ignored header.
