NaiveProxy Cronet Fork

This fork of NaiveProxy adds cronet static library support for cronet-go.

Based on NaiveProxy v140 (Chromium 140.0.7339.123).

Changes from naiveproxy upstream

Build Configuration Changes

File	Change	Reason
src/BUILD.gn	Add //components/cronet:cronet_static	Build cronet static library
src/build/config/cronet/config.gni	is_cronet_build = true	Enable cronet build mode, avoid mojo dependency
src/net/features.gni	Disable enable_mdns	Avoid re2 dependency
src/net/features.gni	Disable include_transport_security_state_preload_list	Preload list JSON not included
src/net/features.gni	Disable enable_device_bound_sessions	Avoid sqlite_proto dependency
src/net/features.gni	Disable enable_disk_cache_sql_backend	Avoid sql dependency
src/url/features.gni	use_platform_icu_alternatives = true	Avoid ICU dependency
src/third_party/perfetto/gn/perfetto.gni	perfetto_build_with_embedder = true	Use Chromium paths

Bug Fixes

File	Change	Reason
src/net/socket/client_socket_pool_manager_impl.cc	Set is_for_websockets=false	Fix HTTP/2 ALPN negotiation for BidirectionalStream

Added Components (from Chromium v140)

Directory	Purpose
src/components/cronet/	Cronet core implementation
src/components/grpc_support/	BidirectionalStream C API
src/components/prefs/	Preferences support

Custom API Extensions

File	API	Purpose
src/components/cronet/native/include/cronet_c.h	Cronet_CreateCertVerifierWithRootCerts()	Custom root certificate validation
src/components/cronet/native/include/cronet_c.h	Cronet_CreateCertVerifierWithPublicKeySHA256()	Certificate pinning by public key SHA256 hash
src/components/cronet/native/engine.cc	Implementation	Support custom CA certificates and public key pinning

Custom Experimental Options

Option	Parameters	Purpose
DnsServerOverride	nameservers: list of "ip:port"	Override DNS nameservers for the built-in async DNS client

Example:

{
  "AsyncDNS": {"enable": true},
  "DnsServerOverride": {"nameservers": ["127.0.0.1:5353"]}
}

This allows redirecting DNS queries to a local DNS forwarder for custom DNS routing.

Android Stub Files

For Android builds without JNI (native-only Go binding), stub implementations replace JNI-dependent code:

File	Replaces	Purpose
src/base/android/path_utils_stub.cc	path_utils.cc	Returns empty paths (cache/native lib dirs not needed)
src/base/android/input_hint_checker_stub.cc	input_hint_checker.cc	No-op (UI input detection not needed for network)
src/base/android/android_info_stub.cc	android_info.cc	Uses __system_property_get instead of JNI
src/base/android/java_runtime_stub.cc	java_runtime.cc	Returns 0 for Java heap memory (no JVM)
src/components/prefs/android/pref_service_android_stub.cc	pref_service_android.cc	No-op (Java preference bindings not needed)
src/net/android/network_change_notifier_android_stub.cc	network_change_notifier_android.cc	Provides NetworkChangeCalculatorParamsAndroid() only
src/net/proxy_resolution/proxy_config_service_android_stub.cc	proxy_config_service_android.cc	Returns direct (no proxy) configuration

These stubs resolve linker errors when building cronet for Android without the full Chromium Java/JNI infrastructure.
