Q: “Update the headers” was the most common feedback on incoming pull requests. Was it needed?

A: Checked with OSGeo legal (thanks board):

- headers are an historical artifact from before the Berne Convention

- no longer needed, now just informative.

Header Maintenance

/* (c) 2016 Open Source Geospatial Foundation - all rights reserved * This code is licensed under the GPL 2.0 license, available at the * root application directory. */package org.geoserver.main;

New Headers PolicyThe new copyright header management policy is as simple as:

● Add a copyright header, with the current year, to each new file

● Add a copyright header to each modified file without one (using the current year)

● Otherwise do not change the copyright header when an existing file is modified

Configuration and management

● Allows GeoServer to store resources(icons, fonts, config files) in either file system or database “blobs”.

● Run without a “Data Directory”(Helpful in clustered/cloud environment)

● All instances of file access were converted to resource api

● Backwards compatible - file will be unpacked on disk if required

● Manage via REST API● GUI available as community module

Parametric configuration● Switching data directories between

integration/beta/production environments can be a pain

● GeoServer 2.10 allows to stick parameters in the configuration, and read them from the environment

● Look ma, switching environments without grep/sed on the data dir :-)

● Store params in property file, system or environment variables

2.9 2.10GeoSolutionsEumetsatWorld Bank

Backup/restore community module● 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

2.9 2.10GeoSolutionsEumetsatWorld Bank

Backup/restore community module (cont'd)● Can do a “dry run”

to check if there is any error prior to restore

2.9 2.10GeoSolutionsEumetsatWorld Bank

Backup/restore community module (cont'd)● REST API to run, control,

eventually cancel backups and restores

Heterogeneous mosaics - resolution / projections

2.10BoundlessSOCOM

● Support for mosaics in multiple coordinate reference systems(Coming in 2.10.x)

Excess granule removal ● Optimization for deep z-order mosaic stacks● E.g., time series of scattered data● Do not load imagery that is not contributing to the output

2.9 2.10GeoSolutionsBEV

In development!

Multiple coverages for mosaic and pyramid (2.10)● Already available for multidimensional data (NetCDF, Grib)● Now available also for “flat” data sources● Meaningful if the sources are normally managed and used together (e.g.,

multispectral satellite data and its derived products)

2.9 2.10ImplementorBEV

Coverage view optimizations (2.10)● A coverage view allows to bind together bands from different coverages

coming from the same source (e.g., NetCDF)● Optimization to avoid reading all sources if the style is only using a subset of

the bands

Maintenance &Technical Debt

● Relying on volunteer time to keep an eye on the codebase was not working out

○ team busy on customer work?○ backlog of bugs piling up

● Trying an experiment○ Once a month meeting○ Distributed, on-line code sprint

● When:○ First edition in July○ Second at the end of FOSS4G

Monthly bug fixing code sprints

Monthly bug fixing code sprints● Actions

○ Vet existing tickets○ close invalid/non reproducible ones○ close feature requests that failed to gather

resourcing in a long time...○ Fix bugs

● Nice side effects:○ Gets more developers familiar with the

contents of the issue tracker○ Opportunity to get proficient with new parts

of the code base○ Predictable, scheduled activity

Wicket 7Held sprint in victoria to clear up this long standing technical debt!

Java 8GeoServer now requires Java 8.

Why? What changed ...

- Traditionally GeoServer takes forever to support the latest Java- Oracle now charges for Java 7 security updates

2.9 2.10Joint EffortCommunity

Required to upgrade the “Spring Framework” used to wire GeoServer together:

- We needed a newer version of “Spring” for Java 8 compatibility

- Upgraded to Spring 4 → 2 month delay to GeoServer 2.9 release

Check that your application server supports:

- Servlet 3.0 was released in 2009 - Supported by Tomcat 7 and Tomcat 8

Spring 4

Tiling

MBTiles like storage● Store tiles in MBTiles database● Possibility to use many databases, following a pattern, e.g.,

○ /path/to/{grid}/{dim}/{tileset}/{z}/{x}-{y}.sqlite (x and y are actually groups of values)○ Helps with scalability, especially if not fully seeded

● Allows to store non Google Mercator projections (extension)● Allows to store formats other than png or jpeg (extension)● Stores in lookup table creation date for expiration support● REST API to replace single files (automate migration from seeding

machine to serving ones)● Not compatible with disk quota!

WMS/WMTS ND discovery extensions

● Data with N dimensions (time, elevation, custom ones)● Dimensions can be related (forecasts, time and run time), the data can be

scattered (remote sensing)● Add extra calls to query the domains. Like, if I fix a given time and bbox, what

residual ranges of elevations and run-times are available?● Add extra calls to list specific items in a small domain (full enumeration of

possible combinations

2.9 2.10GeoSolutionsBEV

WPS

Aggregation with group-by (2.9)● The aggregation

process has been extended with group-by capabilities

● Quick way to power custom charts on your client side

{ "GroupByAttributes": [ "groupingAttribute" ], "AggregationResults": [ [ "Class1", 18 ], [ "Class2", 1 ], [ "Class3", 3 ], [ "Class4", 3 ] ], "AggregationFunctions": [ "Count" ], "AggregationAttribute": "countingAttribute"}

2.8 2.9 2.10GeoSolutionsLiguria Digitale

Improved WPS resource control (2.10)● Processes are run in thread pools, they

can wait for their execution slot in queue● Separate control for total time, and pure

execution time

2.10utas.edu.au

Download process improvements (community module)● Community module for clip and

ship support● Asynch requests allow for large

extractions● Can have maximum extraction

limits configured● Added ability to also select

bands, and improved output size estimation

WPS

2.9 2.10GeoSolutionsBEV

Large raster extraction optimizations

● Optimizing many concurrent large masked raster extractions via Download process (e.g. 128 concurrent requests at the bigtiff threshold)

● Improved both scalability and reliability under sustained load on a “big iron” (40 cores, 128GB memory)

2.9 2.10GeoSolutions 2.8

Security

LDAP User Group Service● We previously only had an “authentication

provider”, meaning, it used the username/pw provided and tried to open a LDAP connection with them

● We now also have a “user group service”,it opens a LDAP connection using fixed credentials, and searches the user in the LDAP database, matching the password

● E.g., similar to storing users in a DBMS

2.10Niels Charlier?

Integrated GeoFence community module● Allows to define complex rules without running

a separate GeoFence server● UI to edit rules● REST API to automate rule editing

2.8 2.9 2.10Niels Charlier?

Integrated GeoFence community module (cnt’d)● Separate page for “admin” rules, that is, rules

controlling administration level access● Used to setup workspace specific admins and

the like

Looking Ahead

Java 9 CompatibilityJava 9 has been delayed until 2017, but we would like to ensure GeoServer will function. Oracle will stop shipping free security updates to Java 8 on

We have a couple incompatibilities with the GeoTools “service provider interface” plugin system that we will look at resolving during the code sprint!

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 EngineJoint OSGeo / LocationTech game plan:

● Raster Processing Engine APIdefinition of raster-processing-api

● Raster Processing Enginereference pure-java implementation

● Raster Processing Wrapperbenchmark jai-wrapper implementation

● GeoTools Replace JAImigrate to raster processing engine api and coordinate transition affected projects (GeoServer, GeoNode, uDig, GeoScript, etc...)
