James Peach commented on MESOS-8368:
------------------------------------
Probably we should implement [SSL_CTX_set_next_protos_advertised_cb
|https://www.openssl.org/docs/man1.1.0/ssl/SSL_set_alpn_protos.html] and only
advertise {{http/1.1}}. This ought to prevent HTTP/2 negotiation, though it
seems pretty aggressing of curl to try HTTP/2 without an explicit negotiation.
> Improve HTTP parser to support HTTP/2 messages.

> Key: MESOS-8368
> URL: https://issues.apache.org/jira/browse/MESOS-8368
> Project: Mesos
> Issue Type: Improvement
> Reporter: Armand Grillet
>
> We currently use [http-parser|https://github.com/nodejs/http-parser] to parse
> HTTP messages. This parser does not work with HTTP/2 requests and responses
> which as an issue as curl enables HTTP/2 by default for HTTPS connections
> since its version 7.47.
> The issue has been discovered in some of our tests (e.g.
> ProvisionerDockerTest) where it crashes with the message {{Failed to decode
> HTTP responses: Decoding failed}}. See
> [MESOS-8335|https://issues.apache.org/jira/browse/MESOS-8335] for more
> details.
> Possible long-term solutions:
> * Upgrade the parser to be compatible with HTTP/2 messages.
> [http-parser|https://github.com/nodejs/http-parser] has not been updated
> regularly this past year in favor of
> [nghttp2|https://github.com/nghttp2/nghttp2] which has a much broader scope.
> [There is no equivalent of http-parser for HTTP/2
> yet|https://users.rust-lang.org/t/is-there-anything-similar-to-http-parser-but-for-http2/10721].
> * Test which version of curl is used at startup and report an error if the
> version is >= 7.47 and the flag {{--http1.0}} is not used in curl (more
> details regarding this flag are available
> [here|https://curl.haxx.se/docs/manpage.html].
> In the meantime, we are upgrading our testing machines using a recent version
> of curl to run with the flag {{--http1.0}}
> ([MESOS-8335|https://issues.apache.org/jira/browse/MESOS-8335]).
