From cf562a7697243b425d3d9230770e885aacd19888 Mon Sep 17 00:00:00 2001 From: Bhagirath Mehta Date: Tue, 17 Mar 2026 23:52:56 -0500 Subject: [PATCH 01/34] Modernize GitHub Actions workflows and fix CI issues Update all actions to latest major versions: - actions/checkout: v1/v2/v3 -> v4 - actions/setup-java: v3 -> v5 - android-actions/setup-android: v2 -> v3 - microsoft/setup-msbuild: v1.1 -> v2 - actions/upload-artifact: v2 -> v4 Fix Android CI: - Use sdkmanager from PATH (setup-android v3 adds it automatically) instead of hardcoded cmdline-tools/7.0/bin directory - Replace hardcoded C:\Users\runneradmin with \C:\Users\bhamehta Fix Windows CI: - Update vs-version from [16,) to [17,) to match VS 2022 runners Fix iOS/macOS CI: - Replace deprecated macos-13 runner with macos-14 - Update iOS deployment target to 14.0 - Update simulator matrix for macos-14/macos-15 runners General: - Add concurrency groups to cancel superseded workflow runs - Updates apply to both active and disabled (.off) workflows Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> --- .github/workflows/build-android.yml | 16 ++++++++++------ .github/workflows/build-ios-mac.yml | 17 +++++++++++------ .github/workflows/build-posix-latest.yml | 7 ++++++- .github/workflows/build-ubuntu-2204.yml | 7 ++++++- .github/workflows/build-windows-clang.yaml.off | 2 +- .../workflows/build-windows-vs2017.yaml.off | 2 +- .github/workflows/build-windows-vs2022.yaml | 2 +- .github/workflows/codeql-analysis.yml | 18 +++++++++++------- .github/workflows/spellcheck.yml | 7 ++++++- .github/workflows/test-android-mac.yml.off | 4 ++-- .github/workflows/test-win-latest.yml | 11 ++++++++--- 11 files changed, 63 insertions(+), 30 deletions(-) diff --git a/.github/workflows/build-android.yml b/.github/workflows/build-android.yml index 06bce4267..d25e81e72 100644 --- a/.github/workflows/build-android.yml +++ b/.github/workflows/build-android.yml @@ -17,13 +17,18 @@ on: -

This results in: 'Tests must be run on a concrete device'. Fix by resolving the simulator UUID via xcrun simctl and passing -destination id= which is completely unambiguous. This is the recommended approach per xcodebuild docs and actions/runner-images#8621.

Without a timeout the job runs for 6 hours until GitHub Actions kills it.
