Changes

• nogo is a new framework for running static analysis as part of Bazel builds. Developers can write their own analyzers which run alongside the compiler on each Go package. Analyzers may stop the build when they detect problems.
  • nogo can run go vet as a separate subprocess. We intend to migrate vet to the analysis framework in the future.
  • nogo is experimental, and its interface may change over the next few releases. Please try it out and give us feedback though.
  • Thanks to Samuel Tan (@stjj89) for implementing nogo for Bazel, and thanks to Alan Donovan (@alandonovan) for creating the analysis framework nogo is based on, golang.org/x/tools/go/analysis.
• rules_go now uses the new cc_common module to collect C / C++ flags. This ensures compatibility with future versions of Bazel, since the CROSSTOOL-related fields in CcToolchainInfo are being removed soon.
• Because of the above change the minimum supported version of Bazel is now 0.17.2.
• go_download_sdk now supports goos and goarch attributes. These may be useful for remote execution when your execution platform is different from your host platform.
  • The other SDK rules will automatically detect the platform of the SDK instead of detecting the host platform.
• Cgo now declares internal targets in each supported mode that influences the selection of source files and dependencies with build constraints.
  • This means binaries that set goos, goarch, race, or msan attributes and incorporate cgo code are more likely to be correct. Please continue to use --platforms and other command-line flags for configuration instead though, if possible.
  • Unfortunately, analysis is about 15% slower because of the extra targets. We hope to improve this by integrating cgo compilation into the go_library rule itself, but this will take time.
• Arm64 is now supported automatically (thanks to @ArielleA).
