== Sponsoring ==

The Open Source Geospatial Foundation (OSGeo) has a long tradition of organizing code sprints for developers of Open Source GIS software.
(https://wiki.osgeo.org/wiki/Category:Code_Sprints).

An international community/code sprint for OSGeo will take place May 14-17, 2019.

We expect about 50 developers from all over the world to come from various [https://www.osgeo.org/, OSGeo] projects. Whether desktop application, geospatial library, metadata catalog or web mapping: be sure to find products in the list that you use. The sprint is also an opportunity for your developers to meet with the core developers of the projects, get a deeper insight into the software and participate in the development.

This years' sprint will take place at the University of Minnesota - Twin Cities in Minneapolis and will be hosted by [https://research.umn.edu/units/uspatial, U-Spatial] and organized by [https://www.sharedgeo.org/, SharedGeo] and members of the local OSGeo user group (TCMUG).

In addition to the costs of providing the technical infrastructure and space, food and drink for the developers represents the main cost. Morning/afternoon meals and drinks during the day are planned. In addition, we hope to provide several evening meals and social events.

In order to cover these costs we would be overjoyed to accept offers of sponsorship!

What we can offer:
* Your logo on top of the [https://www.osgeo.org/events/OSGeo_Community_Sprint_2019/ community sprint website] as well as on all official documents used during the sprint
* Acknowledgement in all sprint related emails
* Our undying gratitude, which comes in handy when you least expect it (remember that feature you wanted?)

Our sponsorship levels:
* Gold: >= 2500 USD
* Silver: 1500 USD
* Bronze: 750 USD

So...
* get your company talking to the top project developers.
* encourage your GIS developers to take advantage of this opportunity, there is no better opportunity to learn!
* support the software you use - you benefit immediately.

Thank you very much!

== Discussion ==

=== Java has a roadmap? ===

Yes, we had a previous sprint focused on Java 8 compatibility, several features had changed breaking compatibility.

More importantly the Java roadmap has changed to a six-month release cycle:

* six month release cycle is already well underway having started with Java 9 and Java 10.

* Oracle is offering three year LTS releases commercially

* AdoptOpenJDK is setting up LTS releases of OpenJDK .. backed by IBM, Microsoft and others.

* RedHat is focusing on LTS (skipping Java 9 and Java 10) and plans to ship OpenJDK based on Java SE 11

=== Why is updating our open source projects for the Java roadmap a challenge? ===

- Java changed the service provider interface plugin system used by GeoTools, forcing the project to write its own replacement.

- The java runtime has been broken up into modules, not all of which are activated by default. We need to review what sections of the JRE we require and ensure they are turned on.

- Java introduced the module system "jigsaw" providing both a class-path and module-path for loading jars.

- When loaded on the module-path jars are prevented from using the same package. This breaks multi-jar projects like GeoTools library where gt-api defining interfaces, and gt-main providing implementations.

- Jigsaw also locks down aspects of Java reflection, affecting projects like Spring that make heavy use of reflection to "auto wire" GeoServer together. Spring 5 has been released and upgrading to this release will be a key focus.

- With these changes projects like GeoServer need to review of hundreds open source dependencies to determine what other libraries are broken, if an update is available or replacement can be found.

- The java web service framework (responsible for concepts like Servlet and Session) is being removed from Oracle oversight and has been setup as [Jakarta EE Software](https://jakarta.ee).

=== Do you have any experience running sprints? ===

The GeoServer team really benefited from [[Java 2017 Code Sprint|java 2017 code sprint]] and is eager to repeat the success.

== GeoServer Planning ==

Initial planning has started:

* [https://github.com/geoserver/geoserver/wiki/GSIP-171 GSIP 171 Java 18.9 Compatibility] (GeoServer)

Preflight activities:

* dependency audit

Required updates:

* Spring 5 - Older versions of spring are not compatible with Java 11. Upgrading to from Spring 4 to Spring 5 does involve handling some API changes.
* HazelCast - Like Spring, HazelCast involves a lot of reflection.

Module refactor:

* Repackage GeoServer application jars to prevent conflicts at the package level.
* Resulting application can be used on either the CLASSPATH (Java 8) or MODULEPATH (Java 11)

== GeoTools Planning ==

Planning and work is already well underway:

* [https://github.com/geotools/geotools/wiki/Java-9-Compatibility GeoTools Java-9-Compatibility] (GeoTools)

The first completed phase is to allow GeoTools to be used on the classpath:

* [https://github.com/geotools/geotools/wiki/Migrate-Units-to-JSR-363 Migrate Units to JSR-363] (GeoTools)
* [https://github.com/geotools/geotools/wiki/FactoryRegistry-Refactoring-for-Java-9-Compatibility FactoryRegistry Refactoring for Java 9 Compatibility] (GeoTools)

The sprint goal is to refactor the geotools library into modules, allowing the jars to be used on either the classpath (Java 8) or the module path (Java 11).

* [https://github.com/geotools/geotools/wiki/Restructure-GeoTools-into-Jigsaw-modules Restructure GeoTools into Jigsaw modules] (GeoTools)

* Core library refactored into modules

[[File:Gt-modules.png|frameless|GeoTools Java 11 modules ]]

* plugins used to automatic modules to dependencies on the classpath

[[File:Module-path.png|800px|module-path bridge to classpath]]

In the above illustration the gt-svg module is used as an automatic module publishing org.geotools.renderer.style.svg package. It acts as a bridge to the multi-jar project batik still on the classpath, completely masking the fact batik is used used to read and render svg files. The core module gt-renderer publishes select packages for use, while hiding others. It makes use of ServiceLocator to access the IconFactory implemented by gt-svg and never has direct use of the batik implementation.

For this to work the gt-svg jar has been refactored, moving the icon factory the new package org.geotools.style.svg. This was required as the package org.geotools.renderer.style was already published by gt-renderer.

We expect:

* Initial focus is on the core library, refactoring to allow jars to be used on the module path as named modules
* plugins will remain on the classpath, accessed via service locator, any conflicting packages will not be visible to client code

== JTS Topology Suite Activities ==

Results of bonn code sprint:

* [https://github.com/locationtech/jts/pull/274 Add module names for better Java 9/Jigsaw support] (JTS Topology Suite)

JTS jars can be placed on the module-path used as an automatic module, the jars have been supplied am Automatic-Module-Name using a MANIFEST.MF entry.

For an example.application using jts-core as a module add '''module-info''':

module example.application {
requires org.locationtech.jts; // jts-core
}

== GeoNetwork Planning ==

[[https://github.com/geonetwork/core-geonetwork/wiki/OSGeo-Java-codesprint-2018 Strategy for GeoNetwork]]

== Sprint Coordination ==

=== Communication ===

While many of us are meeting in person, we still need to communicate across teams and timezones:

* [https://docs.google.com/spreadsheets/d/1oE6mU4jp-ZL5PebgXf-fuhtf7MY5dzSwPqpMtrzdZ94/edit#gid=1150591858 Java 2018 Code Sprint Activities] - group spreadsheet
* https://gitter.im/OSGeo/Sprint - casual communication, ask for help if you are stuck for more than ten mins
* https://jitsi.org - hangout and share screen

=== Coordination ===

Care is required to commit everything, and hand over work from one timezone to the next.

* Use of the [https://docs.google.com/spreadsheets/d/1oE6mU4jp-ZL5PebgXf-fuhtf7MY5dzSwPqpMtrzdZ94/edit#gid=1150591858 Java 2018 Code Sprint Activities] spreadsheet is key preventing two people working on the same problem.
* Ask on gitter and put your name next to an activity

=== Sprint Activities ===

The sprint is broken up into several stages, goal is to have something deliverable at the end of each stage. Care has been taken to identify activities that can be worked on in parallel.

==== Stage 1 Build and run in JDK 11 ====

''Done when being able to start and run GeoServer on JDK11 with release extensions loaded in''

Everything in our stack builds and run without any flag added, off the classpath (it's ok to have warnings). This will allow us to get JDK 11 builds going.

* '''Compile:''' Andrea has made considerable progress here, to mirror you need to check out and build locally all the dependencies
* '''Tests:''' passing tests can be worked on in parallel, as long as pervious stages were able to compile without tests. This work may require updating some dependencies
* '''Build:''' package release artifacts such as installers and javadocs

==== Stage 2 Reduce warnings from Dependency Analysis Tools ====

''Done when code we have control over has addressed dependency analysis warnings (except split packages)''

This cannot be automated, and is why we have so many people in the sprint!

* '''Resolve Warning:''' Address warnings from our codebase, many warnings provide clear guidance (will need to save split packages to the next stage.)
* '''Upgrade Dependencies:''' Upgrade dependencies to resolve warnings (should still compatible with Java 8 via mule-release jar or similar.)

Coordination using our spreadsheet will be key as dependency upgrades are transitive to downstream projects.

==== Stage 3 Module repackage ====

''Done when split-module warnings are resolved, and geotools demo applications can run on the module path.''

Add automatic module descriptors, eliminate split packages in library projects, add module-info.java only if needed.

* '''Repackage:''' Repackage each codebase as required to address-split modules
* '''Module App:''' Make sure we can run a true module app depending on the automatic modules
* '''Imports:''' Adjust imports and the like as needed in all projects, try to collect migration scripts to help others do the same.

Discussion:

* Choice between using eclipse api baseline to generate migration script, or writing sed scripts by hand.

==== Stage 4 org.opengis repackage ====

''Done when references to org.opengis package are removed''

Swich gt-api away from using org.opengis package, upgrade everything else to follow
* '''Repackage:''' Repackage org.opengis interfaces into appropriate org.geotools package
* '''EMF Model:''' Update emf models and regenerate

Discussion:

* Updating EMF models requires figuring out which version of eclipse was used to generate

=== Postsprint Activities ===

* Blog capturing sprint results and thanking sponsors
* We would like to issue a milestone release giving downstream projects a chance to migrate ahead of January release candidate.

== How to sponsorship ==

Contributions will be put towards travel costs for sprint participants who would be otherwise unable to attend. Any surplus at the end of the event will be turned over to OSGeo or used for a future code sprint. We have set-up the sprint to minimize travel and accommodation costs.

Sponsors will receive the following benefits / honours:

* Your logo at the top of this page
* Mention in project communication (for example the GeoServer 2.15 release announcement)
* The ability to run on a supported java platform
* Our gratitude :)

This event provides the following sponsorship levels:

=== How to Sponsor ===

# Sponsorship is accepted through the Open Source Geospatial Foundation
#* Use [https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=CP5NFWKN2VRFG OSGeo PayPal] link, funds are in USD marked towards "OSGeo Foundation java code sprint".
#* To make alternative arrangements or request an invoice contact OSGeo Treasurer: treasurer@osgeo.org
# Once sponsorship is received the OSGeo [[Treasurer]] will contact you and the event organizers to acknowledge your sponsorship
#* Please have a logo ready for your organization if you wish to be acknowledged publicly
#* Your event sponsorship, at your request, can contribute towards [http://www.osgeo.org/sponsorship being recognized] as an OSGeo Foundation sponsor

=== Sponsorship Outreach ===

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

* Prior sponsors: gaia3d, boundless, ian, geodan, how2map, fossgis, atol, geosolutions, astun
* Local sponsors: astun, vivid solutions, transient software

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).

=== OSGeo Funding Request ===

The following information is requested by OSGeo Board [[Code_Sprint_Guidelines]], the projects involved indicated that we would be planning a sprint during the 2018 budget process.

* [https://docs.google.com/spreadsheets/d/1bSuf32MjgP7NKZcqvV7IilpxakKdocJ4CPUEF8jq5Z4/edit#gid=990228872 Java 2018 Code Sprint Budget]

It is intended to that OSGeo be recognized as hosting this event, rather than acknowledged as a sponsor.
