Jetty/Contributor Release Testing Check List

1. Download the staged releases for jetty[7|8]

wget https://oss.sonatype.org/content/repositories/jetty-[reponumber]/org/eclipse/jetty/jetty-distribution/[jetty-version]/ jetty-distribution-7.[jetty-minor-version].tar.gz wget https://oss.sonatype.org/content/repositories/jetty-[reponumber]/org/eclipse/jetty/jetty-distribution/[jetty-version]/jetty-distribution-8.[jetty-minor-version].tar.gz

The following steps have to be done for both the jetty7 and jetty8 release.

2. Extract them to a directory of your choice

3. Start jetty

cd [installdir] ; java -jar start.jar OPTIONS=rewrite etc/jetty-rewrite.xml etc/jetty-ssl.xml

No exceptions? Good. Proceed. Otherwise investigate.

4. Open http://localhost:8080/ in your favourite browser

You should see the test.war webapp.

5. Go through ALL the tests and verify they work fine.

6. Verify that hot deployment works

touch [pathToJettyDistribution]/contexts/test.xml

Verify that test.war gets redeployed in STDOUT

CometD:

1. clone git://github.com/cometd/cometd.git

git clone git://github.com/cometd/cometd.git

2. edit pom.xml and update jetty-version and repository url to match the current staged release

   <properties>
       <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
       <jetty-version>7.6.2.v20120308</jetty-version>
       <jetty-plugin-version>${jetty-version}</jetty-plugin-version>
       <slf4j-version>1.6.4</slf4j-version>
       <spring-version>3.1.0.RELEASE</spring-version>
   </properties>

   <repository>
     <id>Jetty Staging</id>
     <url>https://oss.sonatype.org/content/repositories/jetty-988/</url>
   </repository>
 </repositories>

3. build cometd

mvn clean install

4. be patient

5. run the loadtest

As it is described here: http://cometd.org/documentation/2.x/howtos/loadtesting Keep the default values, but make sure that you raise the clients setting to 1000. We might change the default to 1000 (currently 100). Run the loadtest until "JIT compilation time" is a close to zero value. (after about 10k calls)

Make sure that the performance results are reasonably fast. On my MacBook Pro i7 2.6ghz dualcore I've:

6. deploy cometd.war to the webapps directory of the jetty-distribution tested above

cp cometd-demo/target/cometd-demo-[version].war [pathToJetty]/jetty-distribution-[jetty-version]/webapps/

7. start jetty and make sure there's no exceptions

cd [pathToJetty] && java -jar start.jar

8. go through all pages of the demo and test them

http://localhost:8080/cometd-demo-2.4.1-SNAPSHOT/

9. All tests green? Yeeeaaaaay!
