            Bug ID: 264307
           Summary: WKWebsiteDataStore proxy API breaks when using HTTP
                    Connect with TLS
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Page Loading
          Assignee: webkit-unassigned at lists.webkit.org

Using an nw_proxy_config_t for HTTP Connect, with TLS enabled, a WKWebsiteDataStore's proxyConfigurations causes the network process to crash and the proxy configuration is then ignored.

Specifically, if we create the proxy this way:
  nw_endpoint_t endpoint = nw_endpoint_create_host("example.com", "8080");
  nw_protocol_options_t tls_options = nw_tls_create_options();
  nw_proxy_config_t proxyConfig = nw_proxy_config_create_http_connect(endpoint, tls_options);

And then set it on proxyConfigurations, serialization/deserialization fails. In the logs, the network process outputs:
nw_proxy_config_create_with_agent_data No protocol definition registered for "tls"
nw_proxy_config_create_with_agent_data Failed to create proxy config, error in deserializing stack

The network process then crashes.

I also manually verified that serializing/deserializing such an nw_proxy_config_t using nw_proxy_config_copy_agent_data and nw_proxy_config_create_with_agent_data results in a nil nw_proxy_config_t.

I've also filed FB13343396 with a sample app.
