bazel-contrib/rules_go v0.23.0

on GitHub

Changes

• rules_go now supports the new API for protocol buffers.
  • To summarize the announcement, there's a new protobuf module, google.golang.org/protobuf (APIv2). The old module, github.com/golang/protobuf (APIv1) has been re-implemented in terms of the new module. Using either API is fine.
  • rules_go will continue to use protoc-gen-go from APIv1 for now, since the APIv2 does not support gRPC, and there is no gRPC generator yet. See the note on gRPC support in the v1.20.0 release notes.
  • Code generated with either module should work with both APIs. However, code generated with older versions of APIv1 will not not work with the latest version of either module.
• rules_go has migrated to Starlark build settings and configuration transitions.
  • Instead of using feature flags like --features=race, you can now use flags like --@io_bazel_rules_go//go/config:race.
  • go_binary and go_test mode attributes such as race, pure, goos, and goarch have been reimplemented using transitions. Conditional dependencies chosen with select should now work correctly.
  • go_binary and go_test now support a gotags attribute, which lets a binary and its dependencies be built with a list of build constraints. This can also be set on the command line with --@io_bazel_rules_go//go/config:tags.
  • Output file paths no longer include extra configuration data. For example, //tests/core/go_binary:hello creates the file bazel-bin/tests/core/go_binary/hello_/hello. Note that output file paths are still not stable and should not be depended on unless the "out" attribute is set explicitly (for rules that support it).

Compatibility

• The minimum supported version of Bazel is now 2.2.0. This version bump was needed to take advantage of support for build settings and configuration transitions.
• Go versions older than 1.13 are no longer supported.
• The deprecated searchpaths and searchpath fields have been removed from GoArchive and GoArchiveData.
