Jetty Http2 connector for Jenkins

[Olivier Lamy]

Hi

I found a bit of time to finsih the changes to add http2 capability for Jenkins via Jetty.

So it's 3 prs to review:

* winstone: https://github.com/jenkinsci/winstone/pull/39

* extras-executable-war: https://github.com/jenkinsci/extras-executable-war/pull/11

* jenkins: https://github.com/jenkinsci/jenkins/pull/2937

To test this http2 connector you need to start jenkins adding alpn-boot in -Xbootclasspath (alpn is not available in java8 but should be in java9 but that's an other story :-) )

In my case, I run with such command:

/Library/Java/JavaVirtualMachines/jdk1.8.0_121.jdk/Contents/Home/bin/java -Xbootclasspath/p:/Users/olamy/repository/org/mortbay/jetty/alpn/alpn-boot/8.1.11.v20170118/alpn-boot-8.1.11.v20170118.jar -jar target/jenkins.war --http2Port=9090

Note the option --http2Port (using default home made generated ssl certificate)

The alpnboot version depends on your jdk version.

I usually find it looking at the mapping in the jetty pom: https://github.com/eclipse/jetty.project/blob/jetty-9.4.x/pom.xml

You will have profiles such:

    <profile>

      <id>8u121</id>

      <activation>

        <property>

          <name>java.version</name>

          <value>1.8.0_121</value>

        </property>

      </activation>

      <properties>

        <alpn.version>8.1.11.v20170118</alpn.version>

      </properties>

    </profile>

So you have the alpn.version to use.

Then get it:

http://repo.maven.apache.org/maven2/org/mortbay/jetty/alpn/alpn-boot/8.1.9.v20160720/alpn-boot-8.1.9.v20160720.jar

or 

http://repo.maven.apache.org/maven2/org/mortbay/jetty/alpn/alpn-boot/${alpn.version}/alpn-boot-${alpn.version}.jar

-Xbootclasspath/p:  only need to contain the downloaded jar.

Cheers

Even if alpn is not available by default, it will be a useful enhancement.
Let's see if we can land it till the next LTS baseline cut-off.

BR, Oleg

Hi

Once all prs are merged I will improve the wiki page here [1] to add http2 parameter and explain how to include alpn.

Cheers

Hi

It's now merged.

Thanks guys for the reviews.

I have added documentation to the page. let me know if this makes sense especially how to get the right alpn-boot jar.

Maybe next week, I will try to provide a more easy way to get this jar. (some tools to automatically download it)

Cheers

Olivier

The feature has been released in 2.71
Thanks for doing it, Oliver
