| "base_commit_note": "PR-31498 was squash-merged into main on 2022-03-08; the merge commit 591f6754b56cb7f6c31fce8c22528bdf0a99556c has the single parent 4d95fa1ac5d31ff450fb2f31b55ce1eb99d6efcb, and diffing against that parent isolates the PR contribution from ~2 weeks of unrelated drift on main. Both the merge-parent and the PR-creation-time tip carry identical content for the 3 PR-touched non-NEWS files (Lib/tomllib/__init__.py and Lib/tomllib/_parser.py do not exist at either; Python/stdlib_module_names.h has the same blob hash); the patches apply cleanly at either. Using merge_parent for consistency with prior CPython instances and to avoid carrying drift commits in the base tree. Same pattern as PEP-617 / PEP-634 / PEP-654 / PEP-669.", |
