4.0.0

The 4.0.0 release brings a number of key improvements to tidy up rules_proto_grpc, along with updates to all of the main dependencies. For most users, 4.0.0 will be a drop-in replacement to the 3.x.x releases and the updates for each language are shown below. Should you have any issues with the new release, please open a new issue or discussion.

The following changes are considered 'breaking', requiring the step to the 4.x.x release cycle:

  • The transitive aspect-based compilation mode using the deps attribute is now completely removed. This mode was deprecated in 3.0.0 and all use of the transitive mode will have shown a warning. If all of your uses of rules_proto_grpc use the protos attribute, 4.0.0 will be no different from 3.x.x. See here for further details. If you have written your own rules for a custom plugin, please see the updated and simplified rule template.

  • The //nodejs aliases for the //js rules have been removed. Again, these were deprecated in the 3.x.x cycle and printed a warning when used. If you are still using these aliases, you can simply change your imports to use the //js prefixed rules.

  • The Rust rules have switched gRPC implementation to grpc. In 3.x.x, we used grpc-rs/grpcio, which wraps the C/C++ implementation of gRPC directly. However, the wrapping process was extremely error prone, with updates of either Rust rules or gRPC causing linker failures and significant maintenance burden. Should you still need grpcio crate support, the 3.1.1 release continues to work but may have issues with newer gRPC versions. The replacement grpc crate is self-described as 'not suitable for production use' but is more readily supportable by these rules in the short term. In the longer term, support for prost and tonic is also on the roadmap, but is waiting for protoc plugins to be available.

  • When using JavaScript library rules, the require path for generated files no longer includes the <target_name>_pb path segment by default. For the previous behaviour, set legacy_path = True on the library. #107

General

  • Updated protobuf to 3.18.0
  • Updated grpc to 1.40.0
  • Updated rules_proto to 4.0.0
  • Documentation has moved to rules-proto-grpc.com. Existing links to the old location will continue to work
  • Transitive aspect-based compilation has been removed
  • The output_files attribute of ProtoCompileInfo has changed from a dict of depsets to a single depset. This is generally an internal implementation detail, so is unlikely to affect any rule users.

C

  • Updated upb to latest

C#/F#

  • Added F# support. #127
  • Updated gRPC to 2.40.0

Go

grpc-gateway

  • Updated grpc-gateway to 2.6.0

Java

  • Updated grpc-java to 1.40.1

JavaScript

  • Breaking change: The require path for generated files no longer includes the <target_name>_pb path segment by default. For the previous behaviour, set legacy_path = True on the library. #107
  • Added package_name attribute to library rules, which allows customising the package name of the generated library. By default if unspecified, the target name will continue to be used as in previous versions.
  • Updated rules_nodejs to 4.2.0

Ruby

  • Updated rules_ruby to 0.5.2
  • WORKSPACE update needed: The ruby_bundle call in your workspace needs an extra include attribute for grpc to work as expected. Please see the Ruby examples

Rust

  • Updated rules_rust to latest
  • Breaking change: Replaced grpcio with grpc. Please see above description for full details on why grpcio is no longer supportable and the long term aim to support prost and tonic
  • Updated protobuf and protobuf-codegen to 2.25.1

Scala

  • Updated rules_scala to latest
  • Updated ScalaPB to 0.11.5
  • WORKSPACE update needed: Dependencies are now fetched with maven_install. You will need to update your WORKSPACE to match the current example.
