Overview ¶
Package testsupport holds helpers shared across the module's test suites. It carries no production call sites — only *_test.go files import it — so it stays out of the production binary's build graph.

func HardenGitTestEnv ¶
func HardenGitTestEnv()
HardenGitTestEnv prepares the process environment so test fixtures that shell out to git are insulated from the invoking context and from concurrency hazards. Call it once from a package's TestMain — alongside the GIT identity seeding — before m.Run(). It:
- Unsets the git locator vars (GIT_DIR/GIT_INDEX_FILE/...) a parent git hook exports, which would otherwise steer fixture git commands into the parent repo's gitdir/index (G-0250).
- Forces gc.auto=0 / gc.autoDetach=false for every child git via GIT_CONFIG_COUNT, so background auto-gc cannot race fixture commits or TempDir cleanup under load (G-0251).
It is safe to call when the locator vars are already unset (os.Unsetenv on an absent key is a no-op) and safe to call from any package whether or not it shells out to git. os.Setenv/Unsetenv (not t.Setenv) because TestMain has no *testing.T and the changes must apply process-wide for the test binary's lifetime — the same reason the identity vars use os.Setenv (t.Setenv panics under t.Parallel). The enforcement chokepoint (policies.PolicyGitTestEnvHardened) requires this call in every exec-bearing internal/* package's TestMain.
