From 73fe9a44848dfc03c2f8344b77013151ab0cb54b Mon Sep 17 00:00:00 2001 From: connerlphillippi <98125604+connerlphillippi@users.noreply.github.com> Date: Fri, 22 Aug 2025 03:53:57 -0700 Subject: [PATCH] Add Windows code signing setup for x64 builds (#22022) ## Summary - Implements automated Windows code signing for x64 and x64-baseline builds - Integrates DigiCert KeyLocker for secure certificate management - Adds CI/CD pipeline support for signing during builds ## Changes - Added `.buildkite/scripts/sign-windows.sh` script for automated signing - Updated CMake configurations to support signing workflow - Modified build scripts to integrate signing step ## Testing - Script tested locally with manual signing process - Successfully signed test binaries at: - `C:\Builds\bun-windows-x64\bun.exe` - `C:\Builds\bun-windows-x64-baseline\bun.exe` ## References Uses DigiCert KeyLocker tools for Windows signing ## Next Steps - Validate Buildkite environment variables in CI - Test full pipeline in CI environment --------- Co-authored-by: Jarred Sumner Co-authored-by: Claude Bot Co-authored-by: Claude Co-authored-by: autofix-ci[bot] <114827586+autofix-ci[bot]@users.noreply.github.com> --- .buildkite/ci.mjs | 14 +- .buildkite/scripts/sign-windows.ps1 | 464 ++++++++++++++++++++++++ cmake/Options.cmake | 17 + cmake/targets/BuildBun.cmake | 43 +++ scripts/build.mjs | 35 ++ scripts/vs-shell.ps1 | 20 +- src/bake/DevServer/IncrementalGraph.zig | 8 +- 7 files changed, 595 insertions(+), 6 deletions(-) create mode 100644 .buildkite/scripts/sign-windows.ps1 diff --git a/.buildkite/ci.mjs b/.buildkite/ci.mjs index 4c5352a7a0..caaf647428 100755 --- a/.buildkite/ci.mjs +++ b/.buildkite/ci.mjs @@ -434,11 +434,17 @@ function getBuildEnv(target, options) { * @param {PipelineOptions} options * @returns {string} */ -function getBuildCommand(target, options) { +function getBuildCommand(target, options, label) { const { profile } = target; + const buildProfile = profile || "release"; - const label = profile || "release"; - return `bun run build:${label}`; + if (target.os === "windows" && label === "build-bun") { + // Only sign release builds, not canary builds (DigiCert charges per signature) + const enableSigning = !options.canary ?
