State of GeoServer 2.12


Published on

State of GeoServer provides an update on our community and reviews the new and noteworthy features for the Project. The community keeps an aggressive six month release cycle with GeoServer 2.11 and 2.12 being released this year. Each releases bring together exciting new features. This year a lot of work has been done on startup times, large catalogs, REST configuration upgrades, styling languages, styling interface, security,just to name a few. We will also take a look at community research into satellite imagery search and delivery, multi-resolution raster support and more. 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.

  47. 47. Parameter filter cache drop improvements ● GeoWebCache can cache based on parameters like style, time, or elevation. ○ Could not truncate (remove cached tiles) across all parameter values, each must be known and truncated separately. ○ Tiles could be orphaned if the allowed values changed. ○ GeoServer can truncate tiles when the data within them changes, but only caught the default values for parameters other than style ● Added operations for ○ Cross parameter truncate ○ Orphan purge ● Enabled cross parameter truncate on data update GWC 1.12 GS 2.12 Kevin Smith Boundless MapStory
  48. 48. WMS/WMTS multidim domain discovery module (community) ● Data with N dimensions (time, elevation, custom ones) ● Dimensions can be related (forecasts, time and run time), the data can be scattered and found in pockets, hard to locate data in the ND cube ● Add extra calls to query the domains ● Developed as part of OGC Testbed 12 ● See the engineering report and give us feedback: 2.10 Andrea/Nuno GeoSolutions OGC tions
  49. 49. Configuration and management
  50. 50. Security Consideration - Disabled writing by default ● WFS-T allows editing using Transaction requests ○ May not be what you expect? ● Default configuration includes security restrictions on WFS-T functionality ● Restricting editing of data to the administrator account. ● Makes service read-only (while still advertising wfs-t) 2.11Nuno OliveiraCommunity
  51. 51. ● Great performance improvement! ● Test with 10000 layers Faster startup times for large data dirs 2.11AndreaCommunity Version COLD (Startup time seconds) HOT (Startup time seconds) 2.10.1 428 39 2.10.1 + JDCBConfig 62 49 GSIP 155 68 29
  52. 52. ● Great performance improvement! ● Tested on topp:states to make catalog lookup times more evident (assume diff is a constant) Faster runtime times for large data dirs 2.11AndreaCommunity Version Throughput req/sec Avg resp. time ms 2.10.1 169 47 2.10.1 + JDCBConfig 68 117 GSIP 155 233 34
  53. 53. ● When loading a shapefile the PRJ file only matched on AUTHORITY code ● Faster lookup implementation allows GeoServer to search the EPSG database and match far more often Better/Faster EPSG code lookups 2.11AndreaCommunity This reduces a common frustration when configuring new layers in GeoServer
  54. 54. Module “status” REST API (and GUI) ● Verifying what modules are installed was a challenge ● REST API access to the “status page” ● Easy to add additional entries ● Used to check environment for difficult to configure modules that use native code 2.11 Morgan Thompson Boundless Boundless Suite geoserver/rest/about/status
  55. 55. Parametric configuration ● Stick parameters in store configurations and some security bits ● Helps migrating a data dir between environments (e.g., integration/test/beta/production) ● Set the -DALLOW_ENV_PARAMETRIZATION=true system var ● Create a property file with variable values 2.10 Alessio Fabiani GeoSolutions Eumetsat World Bank store_url = file:///var/geoserver/store/teststore
  56. 56. Backup/restore (community) ● Save the configuration to a zip file (not the data!) ● Restore later, in the same or different environment ● UI to run backup and restore ● Asynch operations ○ During backup the configuration is forced read only ○ During restore it’s fully locked 2.10GeoSolutions Eumetsat World Bank
  57. 57. Web interface in Tools / Resource Browser ● Manage and edit resources ● Data Directory or JDBCStore ● Community module ● Packaged plugin coming soon ● REST API sporting equivalent functionality found in core Resource Browser (community) 2.10 Scitus Development Boundless/NGA
  58. 58. Security
  59. 59. OAuth (community) ● Allows GeoServer authentication to be provided by OAuth ● Allows users to login with: ○ GeoNode ○ Google ○ Github ○ … add yours here, it’s pluggable ● Developed for integration with GeoNode 2.10 Alessio Fabiani GeoSolutions Boundless
  60. 60. Security Considerations
  61. 61. Take care to report the issue in a responsible fashion: ● Keep exploit details out of issue report ● Mark the issue as a vulnerability. ● Be prepared to work with Project Steering Committee (PSC) on a solution ● Keep in mind PSC members are volunteers and an extensive fix may require fundraising / resources If you are not in position to communicate in public please consider commercial support, contacting a PSC member, or reaching us via the Open Source Geospatial Foundation at Security Vulnerabilities - Responsible Disclosure
  62. 62. Responsible disclosure policy is working: ● Most users contacted us in a responsible fashion ● One user shared confidential customer report on the user list Where do reports come from? ● Majority reported from security audits ○ Usually performed under contract ○ Automated tools tend to focus on web administration ui, rather than web services ● GeoServer is subject to several security audits a year Security Vulnerabilities
  63. 63. Upgrade to get security fixes ● Security fixes being added to supported versions only ● Please upgrade your GeoServer installations!
  64. 64. Looking Ahead
  65. 65. Java 9 Compatibility Java 9 has been delayed until 2017, but we would like to ensure GeoServer will function. (Oracle stops free security updates to Java 8) We have a couple incompatibilities with the GeoTools “service provider interface” plugin system that we will look at resolving during the code sprint!
  66. 66. The Java Advanced Imaging library enables GeoServer to do all kinds of great image processing! The JAI-EXT project extends this library with replacement no-data / footprint aware operations. Sadly Oracle has not maintained the project, and has not released it as open source. (see Replace-JAI on GeoTools wiki) Raster Processing Engine Joint OSGeo / LocationTech game plan: ● Raster Processing Engine API definition of raster-processing-api ● Raster Processing Engine reference pure-java implementation ● Raster Processing Wrapper benchmark jai-wrapper implementation ● GeoTools Replace JAI migrate to raster processing engine api and coordinate transition affected projects (GeoServer, GeoNode, uDig, GeoScript, etc...)
  67. 67. Thanks!
