Description

6.9.0 (2026-03-02)

Changes:

  • Adjust the resolution order priority of CWL format fields based on preferred ontologies. The IANA Media-Types will be considered first if they can be directly mapped, followed by OGC-based references that are contextually more relevant and easier to interpret by name, and finally the EDAM ontology that offers some additional references, but is harder to interpret due to its unified format_#### naming convention.
  • Add documentation to provide better guidance about installation, configuration and example references.
  • Add weaver.cwl_no_match_user configuration setting to avoid --user parameter on Docker-based CWL execution. This can be desirable when relying on docker rootless mode and/or user namespaces to handle the actual user/group ID mapping. The parameter can also be configured using the WEAVER_CWL_NO_MATCH_USER environment variable.
  • Add WEAVER_CWL_EUID and WEAVER_CWL_EGID environment variables to control the CWL execution user/group ID as alternative to corresponding configuration options.

Fixes:

  • Fix cwltool mapping of output files to staging directory of pywps when multiple nested output directories contain files of matching names leading to conflicting extension errors from flat-list mapping in staging directory. These conflicts are dealt with by cwltool using _<index>. However, those led to side-effect errors when Weaver attempts to enforce strict extension validation between the CWL definition and result format values. A custom PathMapper is applied to the RuntimeContext to preserve the original structure of the CWL results and avoid these conflicts entirely.
  • Fix PyWPS ("server", "sethomedir", "false") configuration to avoid setting HOME directory within the Process worker instance (weaver.processes.wps_package.WpsPackage), which causes docker rootless mode to fail its docker-daemon context resolution due to the modified location.
  • Fix CWL euid/geid resolution using 0:0 which can be desired to let docker rootless mode and/or user namespaces handle the actual user/group ID mapping themselves based on /etc/subuid and /etc/subgid (depends on common-workflow-language/cwltool#2207).
  • Fix CWL format resolution against multiple ontologies (IANA, OGC, EDAM) referring to equivalent media-type definitions to ensure that resolved Job input references match the underlying CWL package execution.
  • Fix CWL format resolution against media-types that support alternative extensions, such as .yaml and .yml. These are cross-resolved against their multiple media-type combinations as application/yaml (official) and legacy application/x-yaml, text/yaml and text/x-yaml.
  • Fix ambiguous resolution between application/netcdf and application/x-netcdf media-types and their resulting ComplexInput/ComplexOutput validators depending on Weaver or pywps based mapping. The official IANA application/netcdf variant will now be used by default when auto-resolved by file extension to ensure consistency between the validation methods.
  • Fix CLI upload operation not forwarding the type media-type property extracted from an input definition. This could occur either when invoking the operation directly, or directly from execute operation which pre-resolved a local file path subject to the Vault upload feature.
  • Fix CLI execute operation not resolving embedded input file references relatively to a specified Job file. If a Job file is provided this way, paths relative to it will be considered for behaviour alignment with CWL. If the files references still cannot be resolved after relative Job path lookup, they will fall back to the CWD, as previously done by the CLI/WeaverClient (fixes #879).
  • Fix CLI execute operation not forwarding format.mediaType (OLD style) and type (OGC style) information correctly when parsing input values from a CWL-style Job structure with class and format definitions (fixes #884).
  • Fix CLI execute operation not properly handling CWL-style Job structures with File array values.
  • Fix missing documentation of the Vault volume mount configuration in the Docker Compose example.
  • Fix missing documentation of the CWL+YAML deployment Media-Type support in the OpenAPI schema.
