Release 6.0.0-pre.20220818.1rc1 (2022-08-24)
Baseline: 62d1b0b2b6c9646855698b5d7f9515521bc37a45
Incompatible changes:
- this incompatible change breaks old instances of http_archive that specified netrc as an absolute path. It is unlikely there are many instances in the wild since the path would refer to a netrc file inside the external repository by absolute path. Migration should be straightforward.
- genrule switched to use exec transition instead of host. This can break targets with hardcoded output paths. To avoid using hardcoded paths use make variables, see https://docs.bazel.build/versions/4.2.2/be/make-variables.html#pre defined_label_variables

- Error Prone now checks for unused return values of additional methods on
java.lang.Object, which can be disabled using --javacopts=-Xep:ReturnValueIgnored:OFF
- Error Prone now checks for unused return values of additional methods on
java.lang.Object, which can be disabled using --javacopts=-Xep:ReturnValueIgnored:OFF
- The --incompatible_existing_rules_immutable_view flag has been flipped to true. See https://github.com/bazelbuild/bazel/issues/13907 for migration notes.
- Split up the C++ archive from the C++ link action and set
CppArchive as mnemonic.
- workspace(managed_directories=) is not available anymore.
- --legacy_important_outputs now has a default of false.
- --legacy_important_outputs default reverted to true.
- objc_library now requires CcInfo in its deps. If this breaks you, add empty CcInfo() to your rule.
- Flag --experimental_local_memory_estimate removed.
- Added a new flag --incompatible_unambiguous_label_stringification, which causes labels in the main repo to stringify into unambiguous forms starting with an @. See https://github.com/bazelbuild/bazel/issues/15916 for more information.
Important changes:
- Deprecate --incompatible_applicable_licenses flag, in preparation for removal in Bazel 6.x.
- Treat py_*.srcs_version="PY2" the same as "PY2ONLY".
- The Build Event Protocol now contains file digests and sizes along with the file name and URI.
- Refactor system suspend event handling.
- alias() can now select() directly on constraint_value()
- Allow scape sequences in Starlark.
- Match remote and local xcode version by most granular version.
- Adds
--experimental_worker_multiplex_sandboxing flag that controls whether to sandbox multiplex workers that support it.
- provider() has a new parameter: init, a callback for performing pre-processing and validation of field values. Iff this parameter is set, provider() returns a tuple of 2 elements: the usual provider symbol (which, when called, invokes init) and a raw constructor (which bypasses init).
- Tests that fail to create or complete their
TestAttemptContinuation by throwing an ExecException will report an INCOMPLETE status. Previously, Bazel would fail to report any status for the test attempt.
- Fixed an issue where Bazel could erroneously report a test passes in coverage mode without actually running the test.
- Include more information about configurations in cquery proto formatted output. This deprecates the configuration field of AnalysisProtosV2.ConfiguredTarget, and adds a new field, configuration_id, to be used instead.
- experimental cc_library.implementation_deps inverted to interface_deps
- In aquery and cquery proto output, indicate if a configuration is a tool or non-tool configuration.
- Include complete configurations in cquery proto output.
- experimental cc_library.implementation_deps inverted to interface_deps
- Make protocOpts() publicly accessible.
- Add some documentation about how configuration information is conveyed in cquery proto output.
- Introduces experimental static library linking API under apple_common.link_multi_arch_static_library
- Further deprecation and removal of pkg_tar. Stop supporting legacy use of 'files' attribute, where it could be a list of labels instead of a map of paths to labels.
- Removed --incompatible_no_build_defs_pkg flag. It never fulfilled its purpose because --all_incompatible_changes would never set it. The last rule it gated (pkg_tar) is scheduled to be removed in Bazel 6.x.
- Add coverage configuration fragment, used to expose output_generator label.
- Bazel now no longer includes system headers on macOS in coverage reports (#14969).
- android_sdk_repository read $ANDROID_SDK_ROOT in addition to $ANDROID_HOME.
- The default dexer is now d8. dx can be optionally enabled using: --define=android_dexmerger_tool=dx_dexmerger
--define=android_incremental_dexing_tool=dx_dexbuilder
--define=android_standalone_dexing_tool=dx_compat_dx
--use_workers_with_dexbuilder
- Packaging support for deploy JAR embedded JDK files (hermetic Java).
- Don't stamp cc_common.link actions for tool dependencies.
- Starlark test rules can use the new inherited_environment parameter of testing.TestEnvironment to specify environment variables whose values should be inherited from the shell environment.
- Enable merging permissions during Android manifest merging with the --merge_android_manifest_permissions flag.
- Allow specialization to work with constraint_values.
- Bazel uses the D8 jar from Maven instead of the SDK.
- Make ijar / java_import preserve classes with
@kotlin.Metadata annotations
- Switch cc_test implementation to Starlark. Note: cc_test will now link statically when targeting Windows regardless of host platform (rather than always linking statically when Windows is the host).
- Switch cc_test implementation to Starlark. Note: cc_test will now link statically when targeting Windows regardless of host platform (rather than always linking statically when Windows is the host).
- Add devtools/build/lib/worker:work_request_handlers to the remote android tools release package. This will be transitively packaged into all_android_tools.
- Bazel uses the D8 jar from Maven instead of the SDK.
- android_sdk_repository read $ANDROID_SDK_ROOT in addition to $ANDROID_HOME.
- Advance android_tools_pkg version to 0.24.0.
- Switch cc_test implementation to Starlark. Note: cc_test will now link statically when targeting Windows regardless of host platform (rather than always linking statically when Windows is the host).
- Bazel uses the D8 jar from Maven instead of the SDK.
- "blaze config" now only reports info from the last build. To compare configurations across multiple builds, redirect "blaze config" output to a file and run your favorite diff tool.
- The --incompatible_override_toolchain_transition flag is now always set, and will be removed in the future. Thus, --noincompatible_override_toolchain_transition has no effect, and the value of the incompatible_use_toolchain_transition parameter in aspect() and rule() builtins is ignored.
- Switch cc_test implementation to Starlark. Note: cc_test will now link statically when targeting Windows regardless of host platform (rather than always linking statically when Windows is the host).
- Toolchain types may now be optional, in addition to mandatory. See https://bazel.build/docs/toolchains#optional-toolchains for further details.
- Add six to deps of has_services=1 py_proto_librarys.
- pkg_tar(symlinks) has been removed. Users needing that feature should migrate to 1.
- Aspects can now define and use exec groups using the same API as rules.
- Removed the obsolete --incompatible_applicable_licenses flag. The feature is permanently enabled.
- embedded_tools packages R8 desugarer again
- Bazel now selects sh path based on execution platform instead of host platform, making it possible to execute sh actions in multiplatform builds. --shell_executable now only applies to actions configured for host.
- labels in genquery.scope are no longer configured.
- When Bzlmod is enabled, all Bzlmod-generated repos will have an extra '@' prepended to their names. This effectively enables the canonical label literal syntax for Bzlmod-generated repos (
@@canonicalRepoName//pkg:target; see https://docs.google.com/document/d/1N81qfCa8oskCk5LqTW-LNthy6EBrDo t7bdUsjz6JFC4/edit?usp=sharing).
- Exposed
CcSharedLibraryInfo to Starlark builtins.
- Enable --use_top_level_targets_for_symlinks by default.
- Singlejar accepts runtime Created-By field
- --noincompatible_disable_managed_directories, and with that, workspace(managed_directories=) is not supported anymore.
- Bazel supports D8 desugaring, albeit without persistent workers
- Remove mtime options from pkg_tar. Users should migrate to
- Test for experimental multiplexed persistent resource processor.
- Added new register_{execution_platforms,toolchains} directives to the MODULE.bazel file, to replace the {execution_platforms,toolchains}_to_register attributes on the module() directive.
- The legacy pkg_tar no longer supports the ability to untar and repackage an input tar file (
deps attribute). Users needed that capability must switch to github.com/bazelbuild/rules_pkg.
cquery's new output mode --output=files lists the output files of the targets matching the query. It takes the current value of --output_groups into account.- Change singlejar metadata to report Created-By Bazel
- Add support for fetching RPC credentials from credential helper.
- Revert interface_deps back to implementation_deps after problem reported in. Use
buildozer 'rename deps implementation_deps' //...:%cc_library; buildozer 'rename interface_deps deps' //...:%cc_library
- Fix for desugaring failure on Bazel+Android+Windows build scenario.
- D8 is the default desugarer
- Migrate main_dex_list_creator to D8 (DX deprecation)
