This PR implements lookup of service descriptor and method descriptor objects in Ruby as described in issue https://github.com/protocolbuffers/protobuf/issues/14891.
It contains three implementations - one for the CRuby extension API, one for JRuby, and one for FFI.
With this patch,
* `DescriptorPool#lookup('fully.qualified.service.name')` works and returns a `Google::Protobuf::ServiceDescriptor` object
* You can call `#options` on that to get the service options
* You can call `#methods` on that to get the services' methods as `Google::Protobuf::MethodDescriptor` objects,
* You can call `MethodDescriptor#options` to get method options
* You can also get the streaming flags & input/output types of the method with `#input_type`, `#output_type`, `#client_streaming`, and `#server_streaming`.
In order to make the FFI implementation work, I had to mark some more methods in the UPB header as exported - I guess that's something which will have to be done on the UPB side, like this 01fed1cc1b
CC @dazuma & @haberman from the original issue, and @JasonLunn (since you work on protobuf it seems - small world!)
I apologies for the large volume of copy-pasta'd code from the existing descriptor class implementations into the new ones - I felt this was probably better than designing new abstractions to reduce it off the bat though; this feels like it "fits in" with the existing implementation.
Closes#15817
, with additional work for JRuby. Partially fixes#1198
An error occurred
by adding support for custom options. Handling of extensions will be handled in a follow up.
Also includes these unrelated fixes:
* Removes code echo between `google/protobuf/repeated_field.rb` and `google/protobuf/ffi/repeated_field.rb` by `require`'ing the former in the latter.
* Adds missing calles to `testFrozen()` from methods of `RepeatedField` under JRuby that mutate.
* Various typos in comments.
Closes#14594
This represents the future direction of protobuf, replacing proto2/proto3 syntax with editions. These will enable more incremental evolution of protobuf APIs through features, which are individual behaviors (such as whether field presence is explicit or implicit). For more details see https://protobuf.dev/editions/overview/.
This PR contains a working implementation of editions for the protoc frontend and C++ code generation, along with various infrastructure improvements to support it. It gives early access for anyone who wants to a preview of editions, but has no effect on proto2/proto3 syntax. It is flag-guarded behind the `--experimental_editions` flag, and is an experimental feature with no guarantees.

Before this CL all messages were generated in the top-level crate module. With
this change we generate messages under the module specified by the package
declaration in the .proto file.
Dots are interpreted as submodule separator in consistency with how C++
namespaces are handled.
Note that name of the proto_library target still remains to be used as the crate name. This CL only adds crate submodules dependeing on the specified package.
