/**
 * Reads lines from `IdnaMappingTable.txt`.
 *
 * Comment lines are either blank or start with a `#` character. Lines may also end with a comment.
 * All comments are ignored.
 *
 * Regular lines contain fields separated by semicolons.
 *
 * The first element on each line is a single hex code point (like 0041) or a hex code point range
 * (like 0030..0039).

We have 3 different things that we synchronize on.

#### Http2Connection

This lock guards internal state of each connection. This lock is never held for blocking operations. That means that we acquire the lock, read or write a few fields and release the lock. No I/O and no application-layer callbacks.

#### Http2Stream

public final class mockwebserver3/junit4/MockWebServerRule : org/junit/rules/ExternalResource {
	public static final field Companion Lmockwebserver3/junit4/MockWebServerRule$Companion;
	public fun <init> ()V
	public final fun getServer ()Lmockwebserver3/MockWebServer;
}

public final class mockwebserver3/junit4/MockWebServerRule$Companion {

public final class okhttp3/android/AndroidAsyncDns : okhttp3/AsyncDns {
	public static final field Companion Lokhttp3/android/AndroidAsyncDns$Companion;
	public fun <init> (Lokhttp3/AsyncDns$DnsClass;Landroid/net/Network;)V
	public synthetic fun <init> (Lokhttp3/AsyncDns$DnsClass;Landroid/net/Network;ILkotlin/jvm/internal/DefaultConstructorMarker;)V
	public fun query (Ljava/lang/String;Lokhttp3/AsyncDns$Callback;)V
}

  assertEquals("/v1/chat/messages/3", request3.getPath());

  // Shut down the server. Instances cannot be reused.
  server.shutdown();
}
```

Your unit tests might move the `server` into a field so you can shut it down
from your test's `tearDown()`.

### API

#### MockResponse

Mock responses default to an empty response body and a `200` status code.

```

Notice how no connect events are fired for the second call. It reused the connection from the first request for dramatically better performance.

### EventListener.Factory

In OkHttp some fields of the address come from the URL (scheme, hostname, port) and the rest come from the [OkHttpClient](https://square.github.io/okhttp/4.x/okhttp/okhttp3/-ok-http-client/).
