GeoServer Code Sprint 2016

Purpose

The GeoServer web administration console is built on top of the Wicket 1.4.x series, which is pretty old and unmaintaned. The purpose of the sprint is to update it to Wicket 7.x, the current stable version.

Due to the large distance between the two releases and the number of backwards incompatible changes accumulated by Wicket in the years this will require the concerted effort of a handful of developers over a few days, including the changes to upgrade the code, and the thorough hand testing of the resulting modified interface.

Sponsors

We would like to extend our thanks to the following sponsors:

Gold Sponsors

Venue and dates

The code sprint will be held in Victoria BC to minimize travel costs. Boundless has offered to provide a venue (either the Boundless Victoria offices or a local technology centre).

The date is tentatively set for the week of January 18th.

This date is selected towards of the GeoServer 2.9 release cycle prior to the code freeze in February, keeping resource availability in mind.

Accommodation and costs

Participants should plan the travel, accommodation and meals.

• Depending on sponsorship level guests to Victoria will be hosted at or billeted with local community.
• At the time of writing accommodation for four guests is available (thanks to Jody Garnett and Martin Davis).

We hope to raise enough financial support to cover overseas travel, and possibly meals.

Sponsorship Outreach

We are reaching out to organizations to see if there is interest in sponsorship:

• International organizations (OSGeo, Boundless, GeoSolutions);

If there is a lot of local sponsorship we expect to drag the developers away from the task at hand and meet the local community (at a social evening or similar).

Sprint

The schedule has been broken down by day to help plan activities for those with limited availability. If you can stop by for an afternoon to help with testing, or volunteer online to test a nightly build, please let the team know.

In scope:

• Use of Java 8 syntax to reduce wicket boiler plate code
• Mike Pumphrey will be on hand to update user guide as each screen is completes manual testing

Out of scope:

• Changing the codebase to use a different library (the effort would be at least an order of magnitude bigger)
• Improve the behavior of the current UI (we can make improvements at the end, once everything works, if time remains)
