Hi all, I'm starting a thread to get us prepared to the Wicket upgrade sprint in January.
We'll have several devs and testers for a limited amount of time, thus it makes sense to do some preparation in advance in order to hit the ground running, and leverage all the people we have starting from the first morning of coding. My plan is to create a wicket7 branch on GeoServer's github, update the deps, and perform some of the changes that can be machine automated, in order to spend time during the sprint on the bits that actually require some brain to be performed. I don't know in advance all the changes that can be automated, but my two previous attempts at upgrading wicket, to 1.5 the first, to 1.6 (wicket 6) the second, provide some good starting point to locate changes that repeat over and over, and also, could be used as quick guidance when in doubt during the sprint: https://github.com/geoserver/geoserver/commits/feature-upgrade-wicket16 Another thing that I would like to do, if I manage, is to drop the dependency towards wicket-spring, since the latter depends on Spring 4, we are not using much out of that module anyways, and during one of my upgrade attempts I already made GeoServerApplication not extend SpringWebApplication anymore. Other changes that are suitable to be done earlier are anything so core that would prevent individual component tests from being run. Other activities that could be carried on early would be checking library compatibility, some Java 8 lambda support and tester improvement guides. Library compatibility wise, we should check that we don't need to upgrade other libs in order to upgrade Wicket. As far as I can tell Wicket core does not depend on much, but we should probably have a look: http://mvnrepository.com/artifact/org.apache.wicket/wicket-core/7.1.0 The lambda support would reduce the usual Wicket boilerplate, we could draw some ideas from these blogs/projects: https://rodrigouchoa.wordpress.com/2015/02/26/apache-wicket-with-lambda-expressions/ https://github.com/rodrigouchoa/wicket-lambda https://github.com/todvora/wicket-lambdamodel https://github.com/wicketstuff/core/tree/master/lambda-parent/lambda A thorn in the back when working with Wicket is the testing, which has been so far, with Wicket 1.4, poor and hard to get right to say the least. It would be cool if someone could look into what Wicket 7 has to offer, and if there is anything useful, write down a little guide on how to perform test upgrades. Some reference here: https://ci.apache.org/projects/wicket/guide/7.x/guide/testing.html Hum... that's what comes to mind right, you're welcomed to contribute more bits to the list, and more importantly, to volounteer on working on an item of your choice. Don't think I'll get quick feedback today, but I'm going to get a wicket7 branch started, will mail back when it's available. Cheers Andrea -- == GeoServer Professional Services from the experts!
