ci(build): run macOS x86_64 lane on self-hosted c2pool-mac-intel runner (#42) - #100
Merged
Conversation
Convert the single arm64-only macos job into an arch matrix: - arm64 -> GitHub-hosted macos-14 (unchanged) - x86_64 -> self-hosted [self-hosted, macOS, X64, c2pool-mac-intel] Activates the macpro-intel-204 self-hosted runner so the macOS x86_64 lane is covered by native CI, resolving the GitHub-hosted macos-13 Intel-runner starvation (#42). Packaging (tag-only) is parameterized by arch and now derives the Homebrew prefix via brew --prefix so it is correct on both Apple Silicon (/opt/homebrew) and Intel (/usr/local).
The self-hosted Intel runner (macpro-intel-204) runs the Actions service from launchd, whose PATH omits Homebrew at /usr/local/bin, so the dep step failed with brew exit 127 (#100). Add a Set up Homebrew PATH step that appends the real brew prefix to GITHUB_PATH so every later step (cmake configure, brew --prefix packaging) resolves brew. GitHub-hosted arm64 keeps /opt/homebrew; fail closed if brew is absent entirely.

Repoint the release matrix's macOS x86_64 cell from GitHub-hosted macos-13 to the self-hosted Intel runner (macpro-intel-204), mirroring build.yml. Port the launchd Homebrew-PATH guard (#100) so brew resolves under the launchd service PATH. arm64 stays on macos-14. Revert: restore 'runner: macos-13' and drop the Set up Homebrew PATH step.

Resolve ARM_SRC and X86_SRC to the staged package dirs so the merge finds both inputs.

…rk fallback Point the Windows job at the self-hosted runner (VM217, labels self-hosted/Windows/X64/c2pool-build) for internal-branch PRs and pushes; fork PRs fall back to GitHub-hosted windows-2022 so untrusted code never executes on the self-hosted box. Completes the self-hosted build fleet (Linux pending VM905 runner registration; macOS x86_64 already self-hosted via #100). Conan cache retained.

Required before exposing a self-hosted runner on a public repo. Verified via the API prior to opening this PR:
all_external_contributorsis the strictest setting — "Require approval for all outside collaborators." No untrusted fork code can reach the self-hosted runner without a maintainer first approving the workflow run.Proof
This PR's own CI exercises
