### Events with Failures

When an operation fails, a failure method is called. This is `connectFailed()` for failures while building a connection to the server, and `callFailed()` when the HTTP call fails permanently. When a failure happens it is possible that a `start` event won’t have a corresponding `end` event.

          override fun connectFailed(
            uri: URI?,
            sa: SocketAddress?,
            ioe: java.io.IOException?,
          ) {
          }
        }

      override val badValue: ProxySelector =
        object : ProxySelector() {
          override fun select(uri: URI?): MutableList<Proxy> = TODO()

          override fun connectFailed(
            uri: URI?,

        override fun connectEnd(
          call: Call,
          inetSocketAddress: InetSocketAddress,
          proxy: Proxy,
          protocol: Protocol?,
        ) = TODO()

        override fun connectFailed(
          call: Call,
          inetSocketAddress: InetSocketAddress,
          proxy: Proxy,
          protocol: Protocol?,
          ioe: IOException,
        ) = TODO()

 *  Fix: Don't double-compress the public suffix database. OkHttp is usually distributed in a
    compressed file (like a JAR or APK), so compressing its internal data was redundant.

 *  Fix: Call `ProxySelector.connectFailed()` when a connection's initial TCP handshake fails.

 *  Fix: Change the signature of `Dispatcher` to accept a nullable `ExecutorService`. Changing this
