1.5.0 (2020-03-25)


  • Adjust incorrectly parsed href file reference as WPS complex input which resulted in failing location retrieval.
  • Partially address unnecessary fetch of file that has to be passed down to CWL, which will in turn request the file as required. Need update from PyWPS to resolve completely (#91, geopython/pywps#526).
  • Adjust WPS output results to use relative HTTP path in order to recompose the output URL if server settings change.
  • Support WPS output results as value (WPS literal data). Everything was considered an href file beforehand.
  • Add additional timeout and retry during fetching of remote file for process jsonarray2netcdf to avoid unnecessary failures during edge case connexion problems.
  • Add support of title and version field of builtin processes.


  • Patch builtin process execution failing since cwltool 2.x update.
  • Avoid long fetch operation using streamed request that defaulted to chuck size of 1. Now, we use an appropriate size according to available memory.

1.4.0 (2020-03-18)


  • Update owslib to 0.19.2
  • Drop support for python 3.5

1.3.0 (2020-03-10)


  • Provide a way to override the external URL reported by WPS-1/2 and WPS-REST via configuration settings allowing for more advanced server-side results in response bodies.

1.2.0 (2020-03-06)


  • Add wps languages for other wps requests types: DescribeProcess and GetCapabilities.


  • Fix a bug where the validation of OneOf items was casting the value to the first valid possibility. Now, it doesn’t change the value if it’s valid without casting it (and still casts it if it’s necessary to make it valid).

1.1.0 (2020-02-17)


  • Simplify docker image generation and make base/manager/worker variants all available under the same docker repo with different tags (#5).
  • Add planned future support of Accept-Language header for WPS-1/2 (geopython/OWSLib 0.20.0) (#74).
  • Improved job logs update with message and progress to allow better tracking of internal operations and/or problems.
  • Allow WPS builtin process jsonarray2netcdf to fetch a remote file.
  • Change doc to point to DockerHub pavics/weaver images.
  • Adjust CI rule long-lasting failures until it gets patched by original reference (gitleaks-actions#3).


  • Fix readthedocs documentation generation.
  • Fix .travis docker image build condition.
  • Fix geopython/OWSLib>=0.19.1 requirement for Python 3.8 support (#62).
  • Fix job update filling due to status location incorrectly resolved according to configured PyWPS output path.

1.0.0 (2020-01-28)

New Features:

  • Add notification_email field to Job datatype that stores an encrypted email (according to settings) when provided in the job submission body (#44).
  • Add ability to filter jobs with notification_email query parameter (#44).
  • Add jobs statistics grouping by specific fields using comma-separated list groups query parameter (#46).
  • Add some tests to evaluate new job search methods / grouping results and responses (#44, #46).
  • Add handling of multiple CWL field format for File type.
  • Add missing ontology reference support for CWL field format by defaulting to IANA namespace.
  • Add support for I/O array of enum (ie: multiple values of AllowedValues for a given input) (#30).
  • Add support of label synonym as title for inputs and process description (CWL specifying a label will set it in WPS process) (#31)
  • Add support of input minOccurs and maxOccurs as int while maintaining str support (#14).
  • Add conformance route with implementation links (#53).
  • Add additional landing page link details (#54).
  • Add weaver.wps_restapi.colander_extras.DropableNoneSchema to auto-handle some schema JSON deserialization.
  • Add weaver.wps_restapi.colander_extras.VariableMappingSchema to auto-handle some schema JSON deserialization.
  • Add more functional tests (#11, #17).


  • Use bump2version and move all config under setup.cfg.
  • Remove enforced text/plain for CWL File when missing format field.
  • Replace bubbling up of too verbose unhandled exceptions (500 Internal Server Error) by summary message and additional internal logging for debugging the cause using an utility exception log decorator.
  • Use the same exception log decorator to simplify function definitions when HTTP exceptions are already handled.
  • Make null reference a singleton so that multiple instantiation calls all refer to the same instance and produce the expected behaviour of <x> is null instead of hard-to-identify errors because of english syntax.
  • Remove unused function weaver.utils.replace_caps_url and corresponding tests.
  • Remove weaver.processes.utils.jsonify_value duplicated by weaver.processes.wps_package.complex2json.
  • Use more JSON body schema validation using API schema definitions deserialization defined by weaver.datatype.
  • Enforce builtin processes registration on startup to receive applicable updates.
  • Provide 2 separate docker images for Weaver manager and worker, corresponding to the EMS/ADES API and the celery job runner respectively.
  • Update Apache license.


  • Adjust some typing definitions incorrectly specified.
  • Fix some failing functionality tests (#11, #17).
  • Fix I/O field ordering preserved as specified in payload or loaded reference file.
  • Fix setting minOccurs=0 when a default is specified in the corresponding CWL I/O (#17, #25).
  • Fix incorrectly overridden maxOccurs="unbounded" by maxOccurs="1" when a partial array input definition is specified without explicit maxOccurs in WPS payload (#17, #25).
  • Fix case where omitted format[s] in both CWL and WPS deploy bodies generated a process description with complex I/O (file) without required formats field. Default text/plain format is now automatically added.
  • Fix case where format[s] lists between CWL and WPS where incorrectly merged.
  • Fix metadata field within a WPS I/O incorrectly parsed when provided by a WPS-1/2 XML process definition.
  • Fix invalid JSON response formatting on failing schema validation of process deployment body.
  • Fix docker images to support pserve when using gunicorn>=20.x dropping support of --paste config feature.
  • Fix multiple Python 2/3 compatibility issues.

  • Add file format validation to generated CWL package from WPS-1 MIME-types.
  • Allow auto-deployment of WPS-REST processes from WPS-1 references specified by configuration.
  • Add many deployment and execution validation tests for WPS1Requirement.
  • Add builtin application packages support for common operations.
