1# Name Resolution
2
3This directory contains the implementation of gRPC's name resolution framework.
4
5## Overarching Purpose
6
7The name resolution framework provides a pluggable mechanism for resolving a logical name into a list of network addresses. This is a key component of gRPC's load balancing and failover systems.
8
9## Files and Subdirectories
10
11- **`resolver.h` / `resolver.cc`**: Defines the core `Resolver` class, which is the main interface for name resolution.
12- **`resolver_factory.h`**: Defines the `ResolverFactory` class, which is used to create `Resolver` instances.
13- **`resolver_registry.h` / `resolver_registry.cc`**: Defines a registry for `ResolverFactory` instances.
14- **`dns/`**: An implementation of name resolution that uses DNS.
15- **`fake/`**: A fake implementation of name resolution for testing.
16- **`google_c2p/`**: An implementation of name resolution that is specific to Google's C2P infrastructure.
17- **`sockaddr/`**: An implementation of name resolution that uses a list of socket addresses.
18- **`xds/`**: An implementation of name resolution that uses XDS.
19
20## Notes
21
22- The name resolution framework is a key component of gRPC's networking infrastructure.
23- It provides a flexible and extensible way to add new name resolution mechanisms to gRPC.
24- The `Resolver` interface is designed to be simple and easy to implement, which makes it easy to add support for new name resolution mechanisms.

1# gRPC C++ Agents Collaboration Guide
2
3This document outlines conventions and best practices for AI-assisted development in the gRPC C++ codebase.
4
5## Preferred Tools & Libraries
6* Prefer gRPC types before absl.
7* Prefer std types when available, use absl types when not
8* Prefer `std::optional` over `absl::optional`
9* gRPC uses C++17, so we can't use C++20 onwards types.
10* The Python implementation cannot depend on the protobuf library, so any shared libraries must expose a C-style API that does not rely on C++ protobuf types.
11
12## Code Style & Conventions
13* `#include <grpc/support/port_platform.h>` is not required unless its macros are needed for compilation.
14* Only include headers that are actively used.
15* Abseil headers are sorted before gRPC headers.
16* For public api headers (in `include/grpc`) we use `<grpc/...>`.
17 * Example: `#include <grpc/grpc.h>`
18* Prefer explicit types over `std::pair` or `std::tuple` for return types.
19* Use `LOG(ERROR)` from `absl/log/log.h` for logging errors, never use `std::cerr` or `gpr_log`.
20* The `fuzztest.h` header is located at `fuzztest/fuzztest.h`.
21
22## About gRPC
23* gRPC uses its own macros for Bazel libraries, tests, etc. Each directory should have a `grpc_package` declaration. For libraries use `grpc_cc_library`, for tests `grpc_cc_test`.
24* Dependencies on non-gRPC libraries (like gtest or absl) are listed in the `external_deps` attribute.
25* The `:grpc` BUILD target is not allowed to depend on the C++ protobuf library, either directly or transitively.
26* Build files for implementation code are typically located in `src/core/BUILD` and `BUILD`. Do not add new `BUILD` files under the `src/` tree without explicit instruction.
27* Tests are located in `test/core` and `test/cpp` (corresponding to the `src` directories). These test directories contain their own `BUILD` files.
28* Fuzz tests use `fuzztest_main` instead of `gtest_main`.
29* When depending on a `grpc_proto_library`, the name of the `cc_library` target is the same as the `name` of the `grpc_proto_library` rule itself, not `[name]_cc_proto` as one might expect from standard Bazel `cc_proto_library` rules. The build system error messages can be misleading in this case.
30* The 'gtest' external_dep also includes 'gmock'.
31* All `upb` related build rules (`grpc_upb_proto_library`, `grpc_upb_proto_reflection_library`) for protos defined anywhere in the repository must be defined in the root `BUILD` file. They should not be placed in the `BUILD` file of the subdirectory where the proto is located.
32* Core end-to-end tests are defined in `test/core/end2end/BUILD` using the `grpc_core_end2end_test_suite` macro. This macro generates multiple `grpc_cc_test` targets by combining a configuration file (like `end2end_http2_config.cc`) with individual test implementation files located in `test/core/end2end/tests/`. The final test target name is created by appending `_test` to the `name` attribute of the macro. For example, `grpc_core_end2end_test_suite(name = "end2end_http2", ...)` generates the test target `//test/core/end2end:end2end_http2_test`.
33* Unused named parameters is a compilation failure.
