We exuberantly announce the release of: mistral 6.0.2: Mistral Project This release is part of the queens stable release series. Download the package from: https://pypi.python.org/pypi/mistral For more details, please see below. 6.0.2 ^^^^^ Bug Fixes * A regression was introduced that caused an error when logging a specific message. The string formatting was broken, which caused the logging to fail. * Mistral was storing some internal information in task execution inbound context ('task_executions_v2.in_contex' DB field) to DB. This information was needed only to correctly implement the YAQL function task() without arguments. A fix was made to not store this information in the persistent storage and rather include it into a context view right before evaluating expressions where needed. So it slightly optimizes spaces in DB. * Evaluation of final workflow context was very heavy in cases when the workflow had a lot of parallel tasks with large inbound contexts. Merging of those contexts in order to evaluate the workflow output consumed a lot of memory. Now this algorithm is rewritten with batched DB query and Python generators so that GS has a chance to destroy objects that have already been processed. Previously all task executions had to stay in memory until the end of the processing. The result is that now it consumes 3 times less memory on heavy cases.
