If the non-Go code starts a new thread, changes the signal mask, and
then invokes a Go function in that thread, the Go runtime will
automatically unblock certain signals: the synchronous signals,
SIGILL, SIGTRAP, SIGSTKFLT, SIGCHLD, SIGPROF, SIGCANCEL, and
SIGSETXID. When the Go function returns, the non-Go signal mask will
be restored.

If the Go signal handler is invoked on a non-Go thread not running Go

file containing it. Then it invokes the host linker (usually gcc) to
combine the go.o object file and any supporting non-Go code into a
final executable. External linking avoids the dynamic library
requirement but introduces a requirement that the host linker be
present to create such a binary.

Most builds both compile source code and invoke the linker to create a

			p = " X:" + goexperiment
		}
	}

	// The go command invokes -V=full to get a unique identifier
	// for this tool. It is assumed that the release version is sufficient

	RulesFor(user user.Info, namespace string) ([]rbacv1.PolicyRule, error)

	// VisitRulesFor invokes visitor() with each rule that applies to a given user in a given namespace, and each error encountered resolving those rules.
	// If visitor() returns false, visiting is short-circuited.

== Step 2. Understanding the Gradle Wrapper
The Gradle Wrapper is the preferred way of starting a Gradle build.
The Wrapper downloads (if needed) and then invokes a specific version of Gradle declared in the build.

In your newly created project, take a look at the files used by the Gradle Wrapper first.

        assertNotNull(classUnderTest.getGreeting(), "app should have a greeting");
    }
}
----

The generated test class has a single _JUnit Jupiter_ test.
The test instantiates the `App` class, invokes a method on it, and checks that it returns the expected value.

== Step 5. Run the App

The Application plugin, which was automatically added by `gradle init`, facilitates creating an executable JVM application:
