Test the new printing plugin

[giohappy]

As mentioned here a new version of the printing plugin is available on Geoserver 2.24.x (currently main) branch, which uses print-lib:2.3-SNAPSHOT. This snapshot is the result of the work done to merge the https://github.com/geosolutions-it/mapfish-print fork into https://github.com/mapfish/mapfish-print-v2 and its refactoring to make it build with Java 11 and the GeoTools API change.
Further details are available at geosolutions-it/mapfish-print#65.

Tests have been already performed in the context of the MapStore framework, where the print-lib is used for its own printing service, and results look good.

In preparation for adopting the updated printing plugin, and getting rid of the forked libs inside Geoserver for GeoNode, we want to do a test drive of Geoserver 2.2.4.x with GeoNode master.

Steps:

• Build Geoserver 2.2.4.SNAPSHOT (Jenkins job) without the inclusion of the forked libs
• Run GeoNode with Docker, with the Geoserver image built and configured with Geoserver 2.24.SNAPSHOT
• execute tests. At the moment no automation tests are available for the printing, and this would be a good opportunity to implement some

Geoserver 2.24.x for GeoNode has been built. Notes:

• it's built from Geoserver main branch with the following command:
  maven -T 4 clean install dependency:tree -Dmaven.wagon.http.pool=false -Dmaven.wagon.http.retryHandler.count=100 -Djava.awt.headless=true -Dtest.maxHeapSize=256M -DskipTests -U -PsldService,printing,monitor,control-flow,wps,kmlppio,wps-download,excel,querylayer,gdal,authkey,css,ysld,importer,wmts-multi-dimensional,backup-restore,oauth2-geonode,oauth2-openid-connect,geofence-server,geofence-wps
• NO custom libs were used

As expected the war contains print-lib-2.3-SNAPSHOT.jar

The layer of Italy is not visible, but we have the PDF and the background at least :)
We need to investigate why the expected layer is not rendered...

The following error is reported:

Is there a testable docker setup?

[print.PDFUtils] - Server returned an error for http://localhost/geoserver[...]

I am always unsure if those calls source at a container (where the route to localhost will fail) or from the client (by which localhost/geoserver would be fine).

Additionally, there is the -DPRINT_BASE_URL=http://geoserver:8080/geoserver/pdf which states the container name.

Will it be enough to change https://github.com/GeoNode/geonode-project/blob/master/docker/geoserver/Dockerfile#L13 to 2.24.0 and changing the .war download path here: https://github.com/GeoNode/geonode-project/blob/master/docker/geoserver/Dockerfile#L24 to the s3 bucket listed in your comment #175 (comment) @giohappy ?

[giohappy]

@gannebamm I paused the tests but this error is due to running docker compose locally, with localhost.
I will report the advancements as soon as I resume them.

2.24.x is not ready for deployment or a switch of geonode master. We're just testing the new print plugin in Geoserver for GeoNode. This test was asked to move the release of Geoserver forward.

[jodygarnett]

2.24-RC is now available and we would love your feedback :)

[giohappy]

@jodygarnett I will resume tests the next few days but I'm quite confident that they will be positive. The only issue I've had so far was do to a misconfiguration.

[jodygarnett]

Perfect, I am just checking in as part of the RC announcement.

I have been really impressed with all the downstream projects testing. I know we do not usually do such big changes, but it is great to know that people have been able to test when needed this time.

[giohappy]

@jodygarnett tests were succesful. I've removed any custom lib from Geoserver for GeoNode and printing still works :)

[jodygarnett]

The 2.24.0 release goes out today and can be shared with GeoNode community.

Thanks for the update @jodygarnett
