From 7c4a8e58188d63f9f83ca888dd33e6973b915351 Mon Sep 17 00:00:00 2001 From: "Miss Islington (bot)" <31488909+miss-islington@users.noreply.github.com> Date: Wed, 29 Oct 2025 10:01:39 +0100 Subject: [PATCH] [3.14] gh-140702: Add test skip for Unix Datagram tests on iOS when on Github Actions (GH-140740) (#140742) Exposes the GITHUB_ACTIONS environment variable to iOS simulator test runs, and uses this variable to skip a Unix Datagram socketserver test that is unreliable in the iOS GitHub Actions environment.
