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)

Open Source Geospatial Foundation
● Strong relationship with OSGeo Foundation
o Incubation to 2009 to 2013
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

Security Vulnerabilities

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

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)

Roadmap
Features and Ideas for 2016

81.
Java 8
● Planned for GeoServer 2.9
o No more “PermGen” space errors
● Java 7 support ended in May
Community PSC 2.9.0

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

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

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”
