May 1, 2025In May 2025, aiida-core delivered notable improvements focused on transport robustness, developer experience, and user guidance. The team removed the SshAutoTransport path in favor of core.ssh_async, boosting performance and simplifying SSH configuration. Key transport edge cases were fixed and async behavior aligned with the manager’s event loop, resulting in more stable remote operations and easier test maintenance. Documentation updates clarify uv virtual environment behavior, and a new warning mechanism helps users identify mismatches between source data and calculation nodes without interrupting workflows. Overall, these changes reduce operational risk, improve reliability, and demonstrate strong async engineering, test modernization, and developer ergonomics.

Apr 1, 2025April 2025 highlights for aiida-core: Delivered a new StashCalculation plugin that enables stashing files or folders from a RemoteData node after a calculation finishes, enabling post-computation data transfer and management. Introduced a CalcJob-based plugin to streamline post-processing workflows and improve data governance. Stabilized CI/CD workflow by reverting recent GitHub Actions dependency bumps, downgrading docker/bake-action from v6 to v5 in docker-build-test.yml and docker-build.yml, and reverting astral-sh/setup-uv from v5.4.1 to v5.2.1 in test-install.yml, restoring reliable workflow execution. Impact: more predictable build pipelines, faster feedback cycles, and enhanced post-calculation data handling. Technologies/skills demonstrated include CalcJob plugin architecture, remote data handling, Docker-based CI/CD tooling, and GitHub Actions workflow maintenance.

Mar 1, 2025March 2025: Delivered three core features in aiida-core that strengthen data safety, developer ergonomics, and storage efficiency. Key outcomes include: (1) CLI enhancement for remote workdir cleanup during node deletion with dry-run and confirmation prompts to prevent data loss; (2) introduction of assert_never to enforce unreachable code paths and improve cross-version safety; (3) support for compressed stash formats via RemoteStashCompressedData, including updates to the StashMode enum and stash option validation. These changes reduce risk, improve code safety, and enable more efficient data management for CalcJobNodes and stash operations. No major bugs fixed this month; integration, CI, and review workflows continue to enhance reliability.

Nov 1, 2024November 2024: Delivered a major feature in aiida-core that improves transport path handling by removing dependencies on the current working directory. Refactored Transport and Engine to enforce absolute paths for all transport operations, eliminating reliance on getcwd() and chdir(), and managing the working directory per operation. This enhances thread safety, supports upcoming async transport workflows, and reduces path-related errors in long-running tasks. Major bugs fixed: none this month.
