docs(go): document test_race/xtest_race and the cctool option - #96
Merged
Conversation
Documents the race detector feature added by hephbuild/heph#390 (commit 5767f260b518cb5bf27af7bd5e41cbb49341ef34): every package with tests now also gets `test_race`/`xtest_race` targets (labels `test-race`, `go-test-race`), and a new `cctool` provider option picks the C compiler a race build stages on Linux (only where race needs cgo; darwin stays hermetic). Updated both doc copies per the reference-drift rule. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XataMo5yVgDy1U3H1bGpFZ

Defaults to the host'sccvia thehostbinprovider (//@heph/bin:cc).buildmodeoverride: a race build always linksexe, even if the selected variant declarespie, since Go's race detector doesn't support PIE on Linux.website/docs/plugins/go.md— addedcctoolto the plugin Options table and a new "Race detector" section.plugins/heph-go/skills/heph-go/references/go-plugin.md— mirrored the same additions in the heph-go skill's distilled reference.Test plan
