Overview

Protocol Buffers for the Rest of Us

Motivation

protoletariat has one goal: fixing the broken imports for the Python code generated by protoc.

Usage

Here's an example of how to use the tool, called protol:

  1. Create a few protobuf files
// thing1.proto
syntax = "proto3";

import "thing2.proto";

package things;

message Thing1 {
  Thing2 thing2 = 1;
}
// thing2.proto
syntax = "proto3";

package things;

message Thing2 {
  string data = 1;
}
  1. Run protoc on those files
$ mkdir out
$ protoc --python_out=out --proto_path=directory/containing/protos thing1.proto thing2.proto
  1. Run protol on the generated code
$ protol --create-init --overwrite -g out --proto-path=directory/containing/protos thing1.proto thing2.proto

The out/thing1_pb2.py file should show a diff containing at least these lines:

-import thing2_pb2 as thing2__pb2
-
+from . import thing2_pb2 as thing2__pb2

How it works

At a high level, protoletariat converts absolute imports to relative imports.

However, it doesn't just convert any absolute import to a relative import.

The protol tool will only convert imports that were generated from .proto files. It does this by inspecting FileDescriptorProtos from the protobuf files.

The core mechanism is implemented using a simplified form of pattern matching, that looks at the Python AST, and if an import pattern is matched and corresponding rewrite rule is fired.

Help

$ protol --help
Usage: protol [OPTIONS] PROTO_FILES...

  Rewrite protoc-generated imports for use by the proletariat.

Options:
  -g, --generated-python-dir DIRECTORY
                                  Directory containing generated Python code
                                  [required]
  -p, --proto-path DIRECTORY      Protobuf file search path(s). Accepts
                                  multiple values.  [required]
  --overwrite / --no-overwrite    Overwrite all generated Python files with
                                  modified imports
  --create-init / --dont-create-init
                                  Create an __init__.py file under the
                                  `generated-python-dir` directory
  --help                          Show this message and exit.

  • Usage on Windows

    Usage on Windows

    I currently am not able to make it work on Windows. However it works in the WSL shell with the same syntax. I keep getting a FileNotFoundError: [WinError 2] on Windows. Am I doing something wrong with the syntax?

    This one is not working:

    protol --create-package --in-place --python-out=cosmospy_protobuf protoc --proto-path=C:\Users\felix\Documents\dev\cosmospy-protobuf\cosmospy_protobuf  C:\Users\felix\Documents\dev\cosmospy-protobuf\cosmospy_protobuf\gogoproto\gogo.proto

    This one is working:

    protol --create-package --in-place --python-out=cosmospy_protobuf protoc --proto-path=/mnt/c/Users/felix/Documents/dev/cosmospy-protobuf/cosmospy_protobuf  /mnt/c/Users/felix/Documents/dev/cosmospy-protobuf/cosmospy_protobuf/gogoproto/gogo.proto

    Same behaviour when using subprocess.run() in a .py file:

    absolute_path = os.path.abspath('cosmospy_protobuf')

#Genrated in a loop but this is how the path is generated
os.path.abspath(os.path.join(root, filename)

cmd = [sys.executable, '-m', 'protoletariat',
           '--create-package', '--in-place',
           '--python-out', 'cosmospy_protobuf',
           'protoc', f'--proto-path={absolute_path}',
           filepath]
subprocess.run(cmd)

    This works on Linux but not on windows

  • fix: ensure every path is decoded using os.fsdecode

    fix: ensure every path is decoded using os.fsdecode

    I'm using Click 7.1.2. For some reason, the input file paths were bytes instead of str, causing lots of errors when I tried to run protol.

    This PR fixed the problem for me. It's probably a safe thing to merge, and it guards against other strange Click incompatibilities.

    In case it matters, here's how I was invoking protol:

    https://github.com/shawwn/tensorflow-checkpoint-reader/blob/c8a77dc82c88f52971f11a96e59d5ace7b595611/build.sh#L15-L16

  • Generated .pyi files include __pycache__, are not idempotent

    Generated .pyi files include __pycache__, are not idempotent

    I've noticed a few things about generated .pyi files:

    • __pycache__ gets picked up and imported,
    • Entries are not sorted (though this isn't really a big deal, it kinda helps with reviewing the diff)
    • Entries get duplicated if run multiple times/generation is not idempotent

    The last one is probably harder to solve since it appears Protoletariat is not assuming it has full control of the pyi (understandable), or else it could overwrite instead of append.

  • mypy not happy with `.pyi` rewriting

    mypy not happy with `.pyi` rewriting

    This project is a great, thank you very much for making and maintaining it.

    I have tried using it with typing however and I notice that mypy is not entirely happy with the rewriting of .pyi files.

    I have setup an example here: https://github.com/aucampia/issue-20221116-python_protobuf_cloudevents/tree/a245d29c2b1600b6580c6db861b4b715e72b9b51

    The specific .pyi file that upsets mypy is generated/protol/_plgen/example/v1/messages_pb2.pyi and the untransformed file is generated/proto/example/v1/messages_pb2.pyi

    With the mypy config from the example, running mypy yields:

    $ python -m poetry run mypy --show-error-codes --show-error-context 
tests/test_conflicting_ns.py:80: note: In module imported here:
generated/protol/_plgen/example/v1/messages_pb2.pyi: note: In member "field_b" of class "Something":
generated/protol/_plgen/example/v1/messages_pb2.pyi:24: error: Name "io.cloudevents.v1.cloudevents_pb2.CloudEvent" is not defined  [name-defined]
generated/protol/_plgen/example/v1/messages_pb2.pyi: note: In member "__init__" of class "Something":
generated/protol/_plgen/example/v1/messages_pb2.pyi:27: error: Name "io.cloudevents.v1.cloudevents_pb2.CloudEvent" is not defined  [name-defined]
Found 2 errors in 1 file (checked 5 source files)
make: *** [Makefile:78: python-validate-static] Error 1

    The specific part of the transformation that is causing the problem is this I believe:

    $ diff -u -r generated/proto/example/v1/messages_pb2.pyi generated/protol/_plgen/example/v1/messages_pb2.pyi

 import builtins
 import google.protobuf.descriptor
 import google.protobuf.message
-import io.cloudevents.v1.cloudevents_pb2
+from ... import io
 import sys

    If I change this by hand to instead do from ...io.cloudevents.v1 import cloudevents_pb2 as io_dot_cloudevents_dot_v1_dot_cloudevents__pb2 and make corresponding changes in the rest of the file to use io_dot_cloudevents_dot_v1_dot_cloudevents__pb2 instead of io.cloudevents.v1.cloudevents_pb2 then mypy is entirely happy.

  • No such option `--descriptor_set_in`

    No such option `--descriptor_set_in`

    It would be great if protoletariat would pass the --descriptor_set_in parameter to protoc compiler. Now it just returns an error:

    Usage: protol protoc [OPTIONS] PROTO_FILES...
Try 'protol protoc --help' for help.

Error: No such option: --descriptor_set_in

  • Error while using `grpc-tools.protoc` for `protoc` subcommand

    Error while using `grpc-tools.protoc` for `protoc` subcommand

    Console error:

      File "/Users/seanchok/Documents/rpc/.venv/lib/python3.10/site-packages/protoletariat/fdsetgen.py", line 137, in generate_file_descriptor_set_bytes

    raise child_exception_type(errno_num, err_msg, err_filename)
FileNotFoundError: [Errno 2] No such file or directory: 'python -m grpc_tools.protoc'

    Steps to reproduce:

    1. install grpc-tools through pip to use protoc

    2. generate python bindings

    python -m grpc-tools.protoc \
  --proto_path=. \
  --python_out=out \
  --grpc_python_out=out \
  *.proto
    1. Use protol protoc
    protol \
  --create-package \
  --in-place \
  --python_out out
  protoc \
  --protoc-path "python -m grpc_tools.protoc" \
  --proto-path .
  *.proto

    My own research:

    1. I read through the proloteriat source code, and suspected that the subprocess.check_output call may not be able to call python to run executable modules just like that. But I'm not entirely sure because the error thrown appears to be FileNotFound.

    2. I created a workaround by first generating the FileDescriptorSet file, and then running protol raw instead of protol protoc.

    touch descriptor.temp

# generate FileDescriptorSet
python -m grpc_tools.protoc \
  --include_imports \
  --descriptor_set_out=descriptor.temp \
  --proto_path=. \
  *.proto

# run post-processing to change absolute imports generated by protoc to relative imports
protol \
  --create-package \
  --in-place \
  --python-out out \
  raw \
  descriptor.temp

    I got the inspiration for the workaround after reading this section of code.

    I'm not sure if protol needs to be updated to make running python -m grpc_tools.protoc possible. Or if this workaround should be made known to other people who are using the grpc-tools package as I am.
