Interceptors
============

Interceptors are a powerful mechanism that can monitor, rewrite, and retry calls. Here's a simple interceptor that logs the outgoing request and the incoming response.

```java
class LoggingInterceptor implements Interceptor {
  @Override public Response intercept(Interceptor.Chain chain) throws IOException {
    Request request = chain.request();

    long t1 = System.nanoTime();

	if !f.PassHost {
		outReq.Host = target.Host
	}

	// TODO: only supports HTTP 1.1 for now.
	outReq.Proto = "HTTP/1.1"
	outReq.ProtoMajor = 1
	outReq.ProtoMinor = 1

	f.rewriter.Rewrite(outReq)

	// Disable closeNotify when method GET for http pipelining
	if outReq.Method == http.MethodGet {
		quietReq := outReq.WithContext(context.Background())
		*outReq = *quietReq
	}
}

<p>
Note that if there are no read-write or write-write data races on memory location <i>x</i>,
then any read <i>r</i> on <i>x</i> has only one possible <i>W</i>(<i>r</i>):
the single <i>w</i> that immediately precedes it in the happens before order.
</p>

<p>
More generally, it can be shown that any Go program that is data-race-free,
meaning it has no program executions with read-write or write-write data races,

        SearchHelper.SearchRequestParamsRewriter rewriter1 = p -> {
            ((MockSearchRequestParams) p).setQuery("rewritten1");
            return p;
        };
        SearchHelper.SearchRequestParamsRewriter rewriter2 = p -> {
            ((MockSearchRequestParams) p).setQuery("rewritten2");
            return p;
        };

        searchHelper.addRewriter(rewriter1);
        searchHelper.addRewriter(rewriter2);

                "- Otherwise, preserve the original translation LINE-BY-LINE, AS-IS.",
                "Do not:",
                "- rephrase or rewrite correct lines just to improve the style.",
                "- add or remove line breaks, unless the original English content changed.",
                "- change formatting or whitespace unless absolutely required.",

	mpz_t zero;

then cgo would rewrite a reference to C.zero by introducing

	var _C_zero *C.mpz_t

and then replacing all instances of C.zero with (*_C_zero).

Cgo's most interesting translation is for functions.  If xxx is a C
function, then cgo rewrites C.xxx into a new function _C_xxx that
calls the C xxx in a standard pthread.  The new function translates

    // the `keys` and `values` arrays do not need to change. But because the "short hash" now has a
    // different number of bits, we must rewrite each element of `entries` so that its contribution
    // to the full hashcode reflects the change, and so that its `next` link corresponds to the new
    // linked list of entries with the new short hash.
