State of GeoServer reviewing the new and noteworthy features introduced in the past year. The project has an aggressive six month release cycle with GeoServer 2.7 and 2.8 being released this year. These releases bring together exciting new features. A lot of work has been done on processing services with clustering, security and processing control. The rendering engine continues to improve with the addition of color blending opening up a range of creative possibilities. The CSS extension (used to easily generate OGC standard styles) has been cleaned up with a rewrite. This talk will highlighted updates on data import, application schema use, data transforms and the latest from the developer list. Attend this talk for a cheerful update on what is happening with this popular OSGeo project. Whether you are an expert user, a developer, or simply curious what these projects can do for you, this talk is for you.

13. SourceForge July Infocalypse
GeoServer has used Source Forge from 2003
• host mailing lists, download artifacts
What went wrong this year:
• A number of poor policy changes
• Extended period of down time in July
We have an exit strategy if required.

14. CodeHaus Shutdown

15. Jira moved to osgeo-org.atlassian.net
OSGeo board
hired consultant
to quickly grab
a backup.
Result now
available on
atlassian cloud
hosting.
Great: All issues and attachments saved
Eeek: No release notes (versions/components missing)

o Transfer copyright in 2014
o Vendor Neutral custodian
● Assistance in 2015
o OSGeo helped mount the “rescue” of issue tracker
contents after CodeHaus shutdown

17. Security Vulnerabilities

18. Please keep in Mind
YOU
are not a
CUSTOMER

19. Please keep in Mind
YOU
are part of a
TEAM

20. Responsible Disclosure
Do:
• Keep exploit details out of issue report
• Be prepared to work with PSC on solution
• Keep in mind PSC members are volunteers
(fix may require fundraising / resources)

21. XEE Vulnerability
OGC protocols parsing XML tricked into
returning the contents of any file on the server.
Resulted in the release of:
• GeoSever 2.7.1.1 (patch release)
• GeoServer 2.6.4
Additional support provided a patch release of:
• GeoServer 2.5.5.1

22. REST API Remote Execution
Administrator could be tricked into running
executable when editing configuration.
Resulted in the release of:
• GeoSever 2.8-RC
• GeoServer 2.6.5
And will be available in
• GeoServer 2.7.3

23. Features and Fixes
Keeping up with the GeoServer Community
Customer ReleaseImplementor

24. Java 7
● We have updated build boxes for Java 7
o Linux (boundless): Oracle JDK, OpenJDK
o Windows (geosolutions):
o OSX (travis): new experiment
● Recommended?
o The build boxes build and test each commit,
why take on the extra testing effort yourself?
o Boundless and GeoSolutions each run build servers
to support the community
Community PSC 2.6.0

25. WFS Cascade: New implementation!
● GeoServer uses new wfs-ng to “cascade”
from remote (or internal) WFS Servers
● Performing 2.6 preflight testing wfs-ng was a
marked improvement over the original
o We have cut over “cold turkey”
o We asked the geoserver-users list for help testing all
those tricky INSPIRE services
● wfs-ng includes configuration overrides
o You can account for several common mistakes
(such as servers that get confused about axis order)

82. Update CITE Tests
● CITE Tests are the OGC conformance tests
● Pass them and you get a cool sticker for
your website
o Well only if you pay
o Idea: Ask OSGeo Board to talk to OGC?
● Tests keep us all safe!
o We would like some time to upgrade / fix
o Help out at the Code Sprint this weekend
Volunteer Andrea Aime 2.9.0

83. JDBC ResourceStore
● Store resources in JDBC Database
o In addition to “Catalog” configuration …
o Store styles, icons, and fonts
o GetFeatureInfo templates
● Approach used
o Direct access to database BLOB
o Great for clustered configurations
Boundless Niels Charlier 2.9.x

84. Layer Group Options
When including layers in a group:
- CQL_FILTER
- INTERPOLATION
- SCALE_RANGE
- Etc…
Boundless Kevin Smith 2.9.0

85. Custom Legend Graphics
● Use your own icon as legend graphic
Boundless Boundless 2.9.x

86. Vector Tiles
• New community module for publishing vector tiles 
• Great solution for modern High Definition Screens
• Use for GeoWebCache for “MapBox without MapBox”
