-Subject: [PATCH 03/11] CGenerator: Protect against being invoked against
- "edition" syntax .proto files
-
-The Google protobuf project is currently experimenting with a new syntax
-for .proto files called "editions". Since protobuf-c is a proto2/proto3
-compiler, after the previous commit reimplementing `FieldSyntax()`, the
-protobuf compiler will abort like this if presented with an "editions"
-syntax .proto file due to the safety check in `FieldSyntax()`:
-
-    $ protoc --experimental_editions --c_out=. test.proto
-    protoc-gen-c: ./protoc-c/c_helpers.h:178: int google::protobuf::compiler::c::FieldSyntax(const google::protobuf::FieldDescriptor*): Assertion `syntax == "proto2" || syntax == "proto3"' failed.
-    --c_out: protoc-gen-c: Plugin killed by signal 6.
-
-On protobuf 26, our `CodeGenerator` can implement certain methods to
-declare that we "support" editions, and then reject any other edition
-except proto2 and proto3, which have apparently been retroactively
-declared to be "editions". Of course this needs to be wrapped in a
-version guard.
-
-With this protection in place, the protobuf compiler cleanly exits with
-a nice error message like this:
-
-    $ protoc --experimental_editions --c_out=. test.proto
-    WARNING: All log messages before absl::InitializeLog() is called are written to STDERR
-    E0000 00:00:1710988958.296200   20022 descriptor.cc:4620] Invalid proto descriptor for file "test.proto":
-    E0000 00:00:1710988958.296239   20022 descriptor.cc:4623]   test.proto: Edition 2023 is later than the maximum supported edition PROTO3
-    --c_out: protoc-gen-c: Plugin failed with status code 1.
