PROFILE

Duncan Macleod

Over five months, Daniel Macleod contributed to projects such as conda/conda, gwastro/pycbc, and conda-forge/staged-recipes, focusing on reliability and maintainability. He fixed JSON output routing in conda/conda, adding regression tests to ensure correct file and stdout handling. In gwastro/pycbc, he stabilized MacOS ARM64 CI by refining conda-based dependency management and streamlining tox configurations, improving cross-platform testing. Daniel also migrated segment handling to igwn-segments for code consistency and future extensibility. His work in conda-forge included backporting dependency constraints and packaging aiowebdav2, leveraging Python, YAML, and CI/CD practices to enhance ecosystem stability and developer experience.

Aug 1, 2025

August 2025 — Ecosystem readiness for aiowebdav2 packaging in conda-forge/staged-recipes. Delivered packaging scaffolding and metadata to enable eventual inclusion in the conda-forge ecosystem, including versioning, dependencies (aiohttp, lxml), Python version constraints, and a build script. No major bugs fixed this period; stability and packaging hygiene improvements completed. Strengthened alignment with conda-forge standards, enabling broader distribution through established channels.

March 2025: Implemented backport of dependency constraints in repodata for ligo.em-bright to support older builds (targetting v1.2.2 with build numbers < 2). The patch updates dependencies such as astropy, astropy-base, h5py, and pandas to ensure compatibility with legacy environments. Implemented in conda-forge/conda-forge-repodata-patches-feedstock, committed as 0d1209bb2e7ed33129b128149fd16e8f1a78f39c (#963). This work reduces build failures and stabilizes legacy workflows for downstream users and CI pipelines.
