Current Series Release Notes

8.0.0.0rc1-23

New Features

  • Added HTTPProxyToWSGI middleware in front of the Mistral API. The purpose of this middleware is to set up the request URL correctly in the case there is a proxy (for instance, a loadbalancer such as HAProxy) in front of the Mistral API. The HTTPProxyToWSGI is off by default and needs to be enabled via a configuration value. Fixes [bug 1590608] Fixes [bug 1816364]
  • It’s now possible to add reply-to address when sending email.

Bug Fixes

  • Added the “convert_input_data” config property under the “yaql” group. By default it’s set to True which preserves the current behavior so there’s no risk with compatibility. If set to False, it disables the additional data conversion that was initially added to support some tricky cases like working with sets of dicts (although dict is not a hashable type and can’t be put into a set). Disabling it give a significant performance boost in cases when data contexts are very large.
  • “__task_execution” wasn’t always included into the expression data context so the function task() didn’t work properly. Fixes [bug 1823875]
  • For an ad-hoc action, preparing input for its base action was done more than once. It happened during the validation phase and the scheduling phase. However, input preparation may be expensive in case of heavy expressions and data contexts. This has now been fixed by caching a prepared input within an AdHocAction instance.
  • WorkflowExecution database model had only “root_execution_id” to reference a root workflow execution, i.e. the most parent workflow execution in the execution tree. So if we needed to get an entity itself we’d always make a direct query to the database, in fact, w/o using an entity cache in the SQLAlchemy session. It’s now been fixed by adding a normal mapped entity for root workflow execution. In other words, WorkflowExecution class now has the property “root_execution”. It slightly improves performance in case this property is accessed more than once per the database session.
