Examples with ScopedSpan brave.ScopedSpan used on opensource projects

Example 1 with ScopedSpan

use of brave.ScopedSpan in project brave by openzipkin.

the class RedactingSpanHandlerTest method showRedaction.

@Test
public void showRedaction() throws Exception {
    ScopedSpan span = tracing.tracer().startScopedSpan("auditor");
    try {
        span.tag("a", "1");
        span.tag("b", "4121-2319-1483-3421");
        span.annotate("cc=4121-2319-1483-3421");
        span.tag("c", "3");
    } finally {
        span.finish();
    }
    MutableSpan reported = spans.take();
    assertThat(reported.tags()).containsExactly(entry("a", "1"), // credit card tag was nuked
    entry("c", "3"));
    assertThat(reported.annotations()).extracting(Entry::getValue).containsExactly("cc=xxxx-xxxx-xxxx-xxxx");
    // Leak some data by adding a tag using the same context after the span was .
    tracing.tracer().toSpan(span.context()).tag("d", "cc=4121-2319-1483-3421");
    // Orphans are via GC, to test this, we have to drop any reference to the context
    span = null;
    GarbageCollectors.blockOnGC();
    // GC only clears the reference to the leaked data. Normal tracer use implicitly handles orphans
    tracing.tracer().nextSpan().abandon();
    MutableSpan leaked = spans.take();
    assertThat(leaked.tags()).containsExactly(// credit card tag was nuked
    entry("d", "cc=xxxx-xxxx-xxxx-xxxx"));
}

    } finally {
        span.finish();
    }
    assertThat(testSpanHandler.takeRemoteSpan(CLIENT).tags()).containsKey("grpc.message_send.1");
    // Response processing happens on the invocation (parent) trace context
    // Intentionally verbose here to show 10 replies
