Month: 2025-12 — AIIDA Core: Implemented configurable unhandled failure handling in BaseRestartWorkChain to enhance error management flexibility and align with real-world workflow needs. This change introduces a new input option on_unhandled_failure with options abort (default), pause, restart_once, and restart_and_pause, enabling operators to tailor failure responses (abort immediately, pause for review, or restart once with or without subsequent pause). The breaking change also renames the exit code to ERROR_UNHANDLED_FAILURE to better reflect the new behavior. Impact: Reduces wasted compute from rigid restarts, enables safer automated pipelines, and supports teams needing pausing for human-in-the-loop evaluation. The change is co-authored by Carlo Antonio Pignedoli and Giovanni Pizzi. Key commit: a770d7a6e7a727ef1d0bb09cd3e5ae4f3b1d4eb4

Concise monthly summary for 2025-10: Key stability and compatibility work on the conda-forge repodata patches feedstock. Delivered a critical build stability fix by updating plumpy compatibility with kiwipy 0.9.0 to resolve aiida-core build issues, improving CI reliability and downstream compatibility. Demonstrated strong dependency management and patching workflow.

September 2025 monthly summary for eth-cscs/cscs-docs: The key deliverable was standardizing the build environment terminology across the documentation by replacing <build-dir> with <build-path>. This improves consistency and readability with no functional changes. The change is captured in commit 39b3804ab880d6930668b72717e6c26904d91cb7 (message: "📚 Build-uenv: consistently use `<build-path>` (#268)"). Business value includes reduced onboarding friction, clearer contributor guidance, and a solid foundation for future doc updates. Technical accomplishments include terminology standardization and improved documentation quality without impacting runtime behavior.

August 2025 aiida-core monthly summary: Key features delivered: Chmod docstring improvements across transport classes to clarify that mode is an integer representing octal permissions with examples like 0o700 (commit 0eb8fc35fc3d87ad099522d0f96a1f1fa352c196). Major bugs fixed: none reported this month. Overall impact and accomplishments: improves API usability, reduces user confusion, and strengthens cross-transport consistency; supports smoother onboarding and developer productivity. Technologies/skills demonstrated: Python docstring standards, API documentation across modules, transport-layer consistency, and contribution hygiene.

April 2025 monthly summary for aiida-core: Delivered robust nested folder handling in SSH transport puttree, enabling makedirs for parent directories and added tests validating nested folder copying; fixed local_copy_list to preserve nested structures and correctly copy the target directory; updated docs to clarify local_copy_list usage. These changes reduce risk in automated file transfers, improve reliability of remote operations, and support more complex directory structures.
