Release 6.0.0-pre.20220706.4 (2022-07-21)

Baseline: ea8b99c

Cherry picks:

   + 107a54e:
     Fix flag file regexp broken by
     bazelbuild@cb2cd9fd2b65311da92777
     7c35939701add5b879.
   + 1e7127d:

Release 6.0.0-pre.20220630.1 (2022-07-11)

Baseline: fbf9277

Important changes:

  - 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
    @rules_pkg.
  - Test for experimental multiplexed persistent resource processor.

Release 6.0.0-pre.20220608.2 (2022-06-15)

Baseline: 4f5e325

Cherry picks:

   + 442155f:
     Automated rollback of commit
     a0a0d09.

Important changes:

  - Aspects can now define and use exec groups using the same API as
    rules.

This release contains contributions from many people at Google, as well as Kaiqin Chen.

Release 6.0.0-pre.20220601.1 (2022-06-10)

Baseline: 93f6e51

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
  - 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...
  - 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
    bazelbuild#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.

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 \a \b \f \v escape 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 (bazelbuild#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 @rules_pkg.

Important changes:

    Fixes bazelbuild#13047.

    Closes bazelbuild#14310.
  - Fixed an issue where Bazel could erroneously report a test passes
    in coverage mode without actually running the test.
  - Make protocOpts() publicly accessible.
  - Add coverage configuration fragment, used to expose
    output_generator label.
  - Bazel now no longer includes system headers on macOS in coverage
    reports (bazelbuild#14969).

    Closes bazelbuild#14971.
  - 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.

    Closes bazelbuild#14849.

Release 6.0.0-pre.20220517.1 (2022-05-23)

Baseline: 61fd06d

Incompatible changes:

  - Split up the C++ archive from the C++ link action and set
    `CppArchive` as mnemonic.

Important changes:

  - 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.
