Subject [jira] [Commented] (SOLR-7339) Upgrade Jetty from 9.2 to 9.3
Date Wed, 23 Dec 2015 12:34:46 GMT

    [ https://issues.apache.org/jira/browse/SOLR-7339?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15069580#comment-15069580

Uwe Schindler commented on SOLR-7339:
-------------------------------------

bq. We should probably try and isolate what is causing it so we can file a bug, but we would
still need to wait for a good version.

...maybe suggest to Jetty people that they use forbidden-apis with {{jdk-unsafe}} bundled
signatures! :-)

> Jetty 9.3 offers support for HTTP/2. Interest in HTTP/2 or its predecessor SPDY was shown
in [SOLR-6699|https://issues.apache.org/jira/browse/SOLR-6699] and [on the mailing list|http://markmail.org/message/jyhcmwexn65gbdsx].
> Among the HTTP/2 benefits over HTTP/1.1 relevant to Solr are:
> * multiplexing requests over a single TCP connection ("streams")
> * canceling a single request without closing the TCP connection
> * removing [head-of-line blocking|https://http2.github.io/faq/#why-is-http2-multiplexed]
> * header compression
> Caveats:
> * Jetty 9.3 is at M2, not released.
> * Full Solr support for HTTP/2 would require more work than just upgrading Jetty. The
server configuration would need to change and a new HTTP client ([Jetty's own client|https://github.com/eclipse/jetty.project/tree/master/jetty-http2],
[Square's OkHttp|http://square.github.io/okhttp/], [etc.|https://github.com/http2/http2-spec/wiki/Implementations])
would need to be selected and wired up. Perhaps this is worthy of a branch?
