January release
Ian can maybe do it on a Friday, Andrea try to help with the GWC release
Code sprint
Early March tentative time frame
Interest from Boundless, Ian, and well… GeoSolutions (hosting!)
Topic:
-
JDK 9 + maybe JDK 8 updates in the code base (like stream ready support
for feature collection, where we can use lambda for profit)
-
CITE
-
upgrade the test harness
-
make sure the tests are still passing (probably they won’t)
-
add new test that we are missing, WFS 2.0, WCS 2.0, CSW, WMTS 1.0,
WPS 1.0, maybe GML and KML and GeoPackage
-
maybe stand up a reference server for OGC to use, with one test per
workspace/virtual service?
-
REST API switch to Spring MVC (Andrea and Ian worried about making
things worse user wise in terms of bugs) --- idea can we couple also fixing
the actual bug reports in Jira? What about the other modules using restlet,
importer and resource-rest-api
<https://github.com/geoserver/geoserver/wiki/GSIP-137>, rest-upload,
sldService, anything else? Need quite a bit of people.
-
Mapbox style
-
Library upgrades
The sprint does not have to be a single topic, if we can swarm a large
beast good, but if someone wants to join and work on a side topic to
leverage the presence of others, that’s good too.
Andrea having fun with DefaultCatalogFacade
Current issues:
-
Lots of linear scans in it
-
Thread safety issue (big configuration lock)
-
Does not optimize all common lookup patterns (search by id or search by
name)
Implemented a new version that's thread safe and faster. Reference time,
37s to load a fully configured gs/gwc with 10k layers and 10k styles (and
10k cached gwc layers too) out of a hot disk cache.
Experimented with parallel loading too (thread safe right?) but that
implies looking for extensions points on an app context that is not fully
loaded and that is not allowed → we would have to move the loading at the
end of the startup.
Reading the xml faster using java 7 Files, helped a bit in some
experiments, need to revisit.
Mind, feature freeze Feb 18th!!
