Felix 31beb0fb2f Bugfix: grpc python code generation location and file suffix (#8359)
* clang-format

* [Python] Replace . with _ in grpc filename suffix

Having filenames with . like `file.fb.grcp`
is not great for Python. Since dots are used for namespaces.
Replacing all of them with _ eg suffix `foo.bar.baz` will become
`foo_bar_baz`.

Restoring the previous default `_fb` suffix.

* [Python] Use namespace in path

This fixes a regression introduced with:
fb9afbafc7
And generates the grpc file in the namespace folder again.

* Sync commandline docs with web docs

Languages known issues

Python

  • Assert the type required in your server/client since python is able to receive Bytes array or utf8 strings.
def SayHello(self, request, context):
    # request might be a byte array or a utf8 string

    r = HelloRequest.HelloRequest().GetRootAs(request, 0)
    reply = "Unknown"
    if r.Name():
        reply = r.Name()
    # Issues might happen if type checking isnt present.
    # thus encoding it as a `reply.decode('UTF-8')`
    return build_reply("welcome " + reply.decode('UTF-8'))

This can be prevented by making sure all the requests coming to/from python are Bytes array

def say_hello(stub, builder):
    hello_request = bytes(builder.Output())
    reply = stub.SayHello(hello_request)
    r = HelloReply.HelloReply.GetRootAs(reply)
    print(r.Message())

Go

  • Always requires the content-type of the payload to be set to application/grpc+flatbuffers

example: .SayHello(ctx, b, grpc.CallContentSubtype("flatbuffers"))
