0.11.1

Go support

Added support for Go 1.10.2 and 1.9.6.

Bug fixes

• #1452 - Fix build error when go_test contains TestMain but no tests
• #1462 - Refactor coverage support
• #1471 - Fix coverage bugs
• #1478 - Fix coverage issues around cgo. (n.b. coverage with cgo is not supported yet, but it's closer to working than before).

0.11.0

New features

• Go 1.10.1 and 1.9.5 are now supported.
• go_path has been rewritten. This rule can be used to
  generate a GOPATH-like directory tree from a set of Go rules (e.g.,
  go_binary, go_library). It will contain source and data files for those
  rules and their transitive dependencies, including generated files. The
  directory tree may contain copied files, symbolic links, or may be a zip
  archive. This is not complete yet, but it should be usable for simple tools.
• go_embed_data now supports an unpack attribute, which allows it to unpack
  zip and tar archives.
• go_binary supports the c-archive and c-shared link modes.
• go_binary now supports an out attribute, allowing you to write binaries
  with custom names.
• go_test now runs examples.
• Proto library rules for Well Known Types are now defined in the
  @io_bazel_rules_go//proto/wkt package. go_proto_library rules using the
  default, gRPC, and gogo plugins depend on these implicitly. These should be
  used instead of explicit vendored or external versions.
• go_proto_library now supports the importmap attribute.

Notes

• The Bazel minimum version is now 0.10.0.
• We've gotten a number of error reports in builds where multiple packages
  with the same import path are linked into the same binary. This is especially
  common when libraries are in both external repositories and vendor directories.
  • The GoLink action will print a warning when this condition is detected.
    This will be an error in the future.
  • The importmap attribute can be used to disambiguate these cases. Newer
    versions of Gazelle will set importmap automatically for go_library
    and go_proto_library rules in vendor directories. This is similar to what
    the standard Go toolchain does.

0.10.3

Bug fixes

• #1431 - go_proto_library once again can import proto files from go_proto_libraries that were embedded in intermediate go_library dependencies.
• #1428 - compiler now writes valid empty archives instead of 0-byte files when all source files are filtered out by build constraints.
• #1425 - compiler now correctly filters files generated by cgo for tests. This allows tests with mixed internal and external sources to include cgo.

0.10.0

Go rules

• Support for Go 1.10, 1.9.3, 1.9.4, 1.8.6, and 1.8.7.
• go_library supports a new attribute, importmap. This lets you set the "actual" import path of a library, which is what the compiler and linker will see. This is only needed when linking binaries that include multiple packages with the same import path. importpath is still the name by which libraries are imported by source files in other libraries.
• go_test may now include sources from both internal tests (compiled in the same archive as the code under test) and external tests (compiled in a separate archive).
• go_test now recognizes the standard shard_count attribute (see Attributes common to all test rules).
• Removed wtool. Use gazelle update-repos example.com/repo instead.
• Removed old Gazelle tree. Use github.com/bazelbuild/bazel-gazelle instead.

0.9.0

Go rules

• Support for transitive link stamping. You can now set x_defs attributes in go_library rules. Any binary rules that depend on those libraries (directly or transitively) will apply those definitions at link time. See Defines and Stamping for more information.
• Refactored rules and toolchain internals. This doesn't affect normal usage of Go rules, but if you maintain Bazel rules that depend on Go providers and toolchains, see documentation in go/toolchains.rst, especially on GoContext and go_context.
• The library attribute is now deprecated. Please migrate to embed instead. gazelle fix will do this for you automatically.
• Several fixes for cgo, Windows, and ppc64.
• Fixed a bug in the code used to check the minimum Bazel version.

Proto rules

• Support for gogo proto. See GOGO_VARIANTS in proto/BUILD.bazel for available compiler plugins. See gogo/BUILD.bazel for an example.
• Proto files no longer need to set option go_package, and the proto package doesn't need to match the importpath explicitly set in go_proto_library.

Gazelle

Reminder: the old Gazelle tree at go/tools/gazelle is deprecated and will be removed soon (#1199). The new location is github.com/bazelbuild/bazel-gazelle. Please update any tooling you have that builds Gazelle at master.

0.8.1

Go rules

• go_binary now supports goos and goarch attributes. This enables multiple target platforms in the same build.
• Fixed an issue which caused the build to fail with the message: "Unsupported architecture: unknown" on newer Linux distributions. We now default to amd64 when we can't detect the architecture with uname -p on Linux.
• Multiple fixes for builds with --features=pure and --features=race.

Gazelle

• # gazelle:prefix example.com/repo can be used to set the prefix within a subtree.
• Fixed some logic bugs around dependency resolution, deletion of rules, and # gazelle:ignore.

0.8.0

Go rules

• Minimum Bazel version is now 0.8.0.
• The config_setting rules in //go/platform are now based on constraint_values instead of cpu. This means that you can write select expressions that match any platform that the Go SDK targets.
• Go executable files now end with ".exe" on Windows.
• Output paths have changed for nearly all rules to include the target platform and configuration. This preserves the cache when targets are built in different configurations.
• Fixed cgo tag filtering for "pure" builds.
• Support for linux/s390x as a host platform (thanks to @kadamvandita).

Proto rules

• The proto compiler is now selected using an explicit compiler attribute in go_proto_library. We no longer use toolchains for this. This lets you use different plugins for different proto libraries.
• go_grpc_library is now a macro around go_proto_library with a gRPC plugin. We plan to deprecate this soon.

Gazelle changes

• Gazelle builds an index of all libraries in a repository and uses the index to resolve dependencies. This enables multiple vendor directories, Go subtrees not at the repository root, and more.
• # gazelle:exclude can be used to ignore paths in subdirectories, not just files in the current directory.
• Removed the experimental flat mode. We planned to use flat files with new_http_archive / new_git_repository, but this would cause unnecessary work when migrating repositories to Bazel. We're exploring other solutions.
