+# brpc_proto_library: a proto -> cc_library macro that is robust against
+# protobuf and Bazel version churn.
+#
+# Background:
+#   - Old protobuf (< 3.21) used to expose a `cc_proto_library` macro
+#     via `@com_google_protobuf//:protobuf.bzl`; newer protobuf removed
+#     that macro.
+#   - Newer protobuf expects callers to use Bazel's native
+#     `proto_library` / `cc_proto_library` (or the `cc_proto_library`
+#     re-exported from `@com_google_protobuf//bazel:cc_proto_library.bzl`),
+#     but older protobuf does not surface a complete `ProtoInfo`, so
+#     the native rules cannot build it.
+#   - Bazel 8 additionally removed `cc_proto_library` from
+#     `@rules_cc//cc:defs.bzl` (the load now resolves to a stub rule
+#     that fails analysis), forcing every caller to either load it
+#     from `@com_google_protobuf` or replace it.
+#   - Bazel's `load()` is static and cannot be conditional on the
+#     protobuf version, so a single brpc_proto_library.bzl cannot
+#     directly satisfy both old and new protobuf by switching imports.
+#
+# Solution (inspired by https://github.com/trpc-group/trpc-cpp/blob/a69d2950f4a9c16b3cb40a2750c69d8940c96820/trpc/trpc.bzl):
+# We implement the proto compilation rule from scratch (see
+# proto_gen.bzl in this directory). Dependency information is
+# propagated through Bazel's native `ProtoInfo` provider, and the
+# default well-known-proto source is
+# `@com_google_protobuf//:descriptor_proto` -- a `proto_library`
+# whose name has been stable across protobuf 3.x / 27.x / 34.x.

+# brpc's self-implemented proto -> .pb.{h,cc} compilation rule.
+#
+# Cross-protobuf-version compatibility strategy (inspired by trpc.bzl):
+#   1) Do NOT load `@com_google_protobuf//:protobuf.bzl` and do NOT
+#      call `native.cc_proto_library` -- this side-steps the double
+#      incompatibility of newer protobuf removing the macro and older
+#      protobuf missing a complete `ProtoInfo` provider.
+#   2) Do NOT hardcode any protobuf-repo-internal filegroup names
+#      (such as `well_known_protos` / `descriptor_proto_srcs`) -- the
+#      names of those filegroups have shifted between protobuf 3.x
+#      and 27.x+.
+#   3) Propagate dependencies via Bazel's native `ProtoInfo` provider:
+#      callers pass `proto_library` targets through `proto_deps`
+#      (defaulting to `@com_google_protobuf//:descriptor_proto`, a
+#      `proto_library` whose label has been stable across PB versions),
+#      and this rule walks `transitive_sources` / `transitive_proto_path`
+#      to collect .proto source files and protoc `-I` paths -- fully
+#      decoupled from the PB version.
+#   4) Among `brpc_proto_gen` targets themselves, dependencies are
+#      propagated via the custom `BrpcProtoInfo` provider declared
+#      below.
+#
+# Note on minimum Bazel version: this rule itself does not call any
+# Bazel-version-specific API, but it still consumes `ProtoInfo` from
+# `proto_library` targets (e.g. `descriptor_proto`) defined inside
+# the protobuf repo. Protobuf >= 34 calls
+# `ProtoInfo(option_deps = ..., extension_declarations = ...)` in its
+# own `proto_library` implementation, and those fields are only
+# accepted by Bazel >= 8. In other words, the minimum Bazel version
+# brpc requires is whatever the bundled protobuf version requires --
