From 31ed45b6553f841f570278bfef8c630b1882f790 Mon Sep 17 00:00:00 2001 From: Steve Spicklemire Date: Fri, 14 Aug 2026 07:46:10 -0400 Subject: [PATCH 1/2] =?UTF-8?q?fix(ci):=20green=20the=20matrix=20=E2=80=94?= =?UTF-8?q?=20importlib.metadata,=20manylinux=5F2=5F28,=20drop=20cp38?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Three failures on an untouched master (#288), three causes: 1. macos-3.12: `import vpython` itself was broken on fresh 3.12+ environments — vpython/__init__.py imported pkg_resources, and Python 3.12 no longer ships setuptools into new environments. Replaced with stdlib importlib.metadata (3.8+), and python_requires bumped 3.7→3.8 to match. This is a real user-facing bug, not just a CI one: anyone on a clean 3.12 install hits it. 2. aarch64 cp311/cp312: cbor2 — a hard dependency via autobahn — ships only manylinux_2_28 aarch64 wheels for cp311+, so the manylinux2014 (glibc 2.17) container could not use them and fell back to building the C extension from source under QEMU, which fails. Container moved to quay.io/pypa/manylinux_2_28_aarch64. 3. aarch64 cp38: Python 3.8 is EOL and the leg fails outright. Dropped. The windows 3.8/3.9 legs still pass and are left alone — retiring them is a support-policy decision, not a CI repair. Closes #288.

Caught by that CI run. The local check that let it through was a syntax parse, which `del wrong_name` passes; the block is now verified by executing it, which is what should have happened the first time.
