Release 2.0.0 (2019-12-19)

Baseline: 807ed23

Cherry picks:

   + db0e32c:
     build.sh: Fix bug in build script for RC release
   + 85e84f7:
     Set --incompatible_prohibit_aapt1 default to true.
   + 84eae2f:
     Let shellzelisk fallback to bazel-real if it's the requested
     version.
   + d5ae460:
     Fix a typo in bazel.sh

Incompatible changes:

  - --incompatible_remap_main_repo is enabled by default. Therefore,
    both ways of addressing the main repository, by its name and by
    '@' are now considered referring to the same repository.
    see bazelbuild#7130
  - --incompatible_disallow_dict_lookup_unhashable_keys is enabled by
    default bazelbuild#9184
  - --incompatible_remove_native_maven_jar is now enabled by default
    and the flag removed. See bazelbuild#6799
  - --incompatible_prohibit_aapt1 is enabled by default.
    See bazelbuild#10000

Important changes:

  - --incompatible_proto_output_v2: proto v2 for aquery proto output
    formats, which reduces the output size compared to v1. Note that
    the messages' ids in v2 are in uint64 instead of string like in
    v1.
  - Adds --incompatible_remove_enabled_toolchain_types.
  - Package loading now consistently fails if package loading had a
    glob evaluation that encountered a symlink cycle or symlink
    infinite expansion. Previously, such package loading with such
    glob evaluations would fail only in some cases.
  - The --disk_cache flag can now also be used together
    with the gRPC remote cache.
  - An action's discover inputs runtime metrics is now categorized as
    parse time on the CriticalPathComponent.
  - Make the formatting example more like to the written text by
    adding an initial description.
  - An action's discover inputs runtime metrics is now categorized as
    parse time on the CriticalPathComponent.
  - Bazel's Debian package and the binary installer now include an
    improved wrapper that understands `<WORKSPACE>/.bazelversion`
    files and the `$USE_BAZEL_VERSION` environment variable. This is
    similar to what Bazelisk offers
    (https://github.com/bazelbuild/bazelisk#how-does-bazelisk-know-whi
    ch-bazel-version-to-run-and-where-to-get-it-from), except that it
    works offline and integrates with apt-get.
  - We are planning to deprecate the runfiles manifest files, which
    aren't safe in the presence of whitespace, and also unnecessarily
    require local CPU when remote execution is used. This release
    adds --experimental_skip_runfiles_manifests to disable the
    generation of the input manifests (rule.manifest files) in most
    cases. Note that this flag has no effect on Windows by default or
    if --experimental_enable_runfiles is explicitly set to false.

This release contains contributions from many people at Google, as well as aldersondrive, Benjamin Peterson, Bor Kae Hwang, David Ostrovsky, Jakob Buchgraber, Jin, John Millikin, Keith Smiley, Lauri Peltonen, nikola-sh, Peter Mounce, Tony Hsu.

Release 1.2.1 (2019-11-26)

Baseline: 11deef7

Cherry picks:

   + c76c3e5:
     Replace macOS CC path with relative path
   + 63332eb:
     Hardcode path to dirname on macOS
   + ceadf0a:
     Add tool executables (from FilesToRunProvider) to action inputs.
   + dbe63b0:
     Fix some of the bazel Windows tools code to work with GCC.

This release fixes a single regression:
- bazelbuild#10297: Bazel 1.2.0 does no longer run on macOS High Sierra.

It is the same code as Bazel 1.2.0, except that we rebuild the macOS release
binaries with Xcode 10.2.1 to make them backwards compatible with older macOS
versions again.

   + 63332eb:
     Hardcode path to dirname on macOS
   + ceadf0a:
     Add tool executables (from FilesToRunProvider) to action inputs.
   + dbe63b0:
     Fix some of the bazel Windows tools code to work with GCC.

Incompatible changes:

  - Tree artifacts and regular artifact paths can no longer overlap.

New features:

  - Added a special "_validation" output group to enable moving
    "validation actions" off the critical path of builds.

Important changes:

  - The query flag "--host_deps" (commonly used as "--nohost_deps")
    has been renamed to "--tool_deps", and now also removes
    dependencies in any execution configuration from being reported
    in the query output. The previous flag name is deprecated and
    will be removed in a future release.
  - The `cc_common.{compile,link}` APIs can now be used without
    passing the `--experimental_cc_skylark_api_enabled_packages` flag.
  - A list of log paths will be provided in build output.
  - Improve runfiles documentation.
  - Improve documentation on rule outputs.
  - BUILD/.bzl execution errors cause execution to stop, even at
    top-level
  - Multiple Starlark validation errors are reported in a single pass.
  - Introduce --experimental_nested_set_as_skykey_threshold
  - Blaze will prevent idle sleep during test and build actions. Note
    that this does not affect screen savers and will not keep a
    laptop awake if the user forces sleep or closes the lid. This is
    purely to avoid idle sleeping when the user is not interacting
    with the device.
  - Improve testing docs.
  - Incompatible flag
    `--incompatible_validate_top_level_header_inclusions` has been
    added. See bazelbuild#10047 for
    details.
  - Fix an aquery bug with handling malformed queries that crashes
    bazel.
  - List fields on CcLinkingOutputs.
  - [Python] Added flag --incomaptible_default_to_explicit_init_py to
    switch the default value of legacy_create_init to True. With this
    flag enabled, your py_binary and py_test targets will no longer
    behave as if empty __init__.py files were implicitly littered in
    your runfiles tree. See
    [bazelbuild#10076](bazelbuild#10076).
  - Fix documentation on allowed target names.
  - --target_platform_fallback now also applies to exec/host
    configurations
  - android_binary and android_libary can now depend on targets
    providing
    CcInfos.
  - Add support for tracking suspensions (sleeps or SIGSTOP) on macOS.
  - d8 dexers (both standalone and incremental) are now available for
    use.
  - Add Desugar support for FreezePeriod#<init>

     Update java_tools version to javac11-v5.1.

Incompatible changes:

  - Python, Windows: the
    --[no]incompatible_windows_escape_python_args is no longer
    supported. (It was flipped to true in Bazel 0.27.0)
  - --incompatible_use_native_patch is enabled by default
  - Windows: --incompatible_windows_bashless_run_command is now true
    by default, meaning "bazel run //foo:bin" will run the binary as
    a subprocess of the Bazel client. (When the flag is false, the
    binary is executed as a subprocess of Bash.)
  - Windows: --incompatible_windows_native_test_wrapper is enabled by
    default

New features:

  - Genrule now supports `cmd_bash`, `cmd_ps`, `cmd_bat` attributes.
    More details at
    https://docs.bazel.build/versions/master/be/general.html#genrule.c
    md
  - config_setting can now check multiple values on "--foo=firstVal
    --foo=secondVal ..."-style flags
  - tags: use `--experimental_allow_tags_propagation` flag to
    propagate tags to the action's execution requirements from
    targets. Such tags should start with: `no-`, `requires-`,
    `supports-`, `block-`, `disable-`, `cpu:`. See bazelbuild#8830 for details.
  - Users can now get generated def file from cc_library via
    "def_file" output group on Windows.
  - Platform-specific bazelrc: with --enable_platform_specific_config
    you can
    enable flags in bazelrc according to your host platform.
  - tags: use `--experimental_allow_tags_propagation` flag to
    propagate tags to the action's execution requirements from
    cc_library or cc_binary targets. Such tags should start with:
    `no-`, `requires-`, `supports-`, `block-`, `disable-`, `cpu:`.
    See bazelbuild#8830 for details.
  - tags: use --experimental_allow_tags_propagation flag to propagate
    tags to the action's execution requirements from java targets.
    Such tags should start with: no-, requires-, supports-, block-,
    disable-, cpu:. See bazelbuild#8830 for details.

Important changes:

  - Bazel Android builds now use aapt2 by default. To revert to aapt,
    set `--android_aapt=aapt`.
  - Make either --subcommands or --verbose_failures imply
    --materialize_param_files
  - Bazel Android builds now use aapt2 by default. To revert to aapt,
    set `--an...
    RELNOTES: None
  - by default all remote connections considered to be via `gRPC`
    with TLS enabled, unless other specified. To disable TLS use
    `grpc://` prefix for you endpoints. All remote connections via
    `gRPC` affected - `--remote_cache`, `--remote_executor` or
    `--bes_backend`. http cache/executor is not affected. See bazelbuild#8061
    for details.
  - cc_* rules support non-transitive defines through a
    'local_defines' attribute.
  - Enable
    incompatible_disallow_rule_execution_platform_constraints_allowed
    by default (bazelbuild#8136).
  - incompatible_disallow_split_empty_separator is enabled by default
  - Fixed Android build issues with aapt2 on Windows. See the [GitHub
    issue](bazelbuild#9102) for more
    information.
  - --incompatible_disable_static_cc_toolchains has been flipped. See
    bazelbuild#8546.
  - --remote_default_platform_properties has been deprecated in favor
    of --remote_default_exec_properties.
  - The --incompatible_make_thinlto_command_lines_standalone flag has
    been flipped, see bazelbuild#6791
    for more information.
  - The --incompatible_use_specific_tool_files flag has been flipped.
    See bazelbuild#9126 for more
    information.
  - Clarify default visibility.
  - Enables incompatible_auto_configure_host_platform
  - New incompatible flag --incompatible_disable_depset_items
    disables the "items" parameter in the Starlark depset
    constructor. Use "direct" and "transitive" parameters instead.
  - --incompatible_assignment_identifiers_have_local_scope is enabled
  - incompatible_disable_partition_default_parameter is enabled by
    default ()
  - incompatible_restrict_attribute_names is enabled
    (bazelbuild#6437)
  - The --incompatible_disable_nocopts flag has been flipped. See
    bazelbuild#8546 for more
    information.
  - Deprecated Java-Starlark API java_common.create_provider is
    removed. JavaInfo() legacy args (actions, sources, source_jars,
    use_ijar, java_toolchain, host_javabase) are removed.
  - The flag incompatible_disallow_hashing_frozen_mutables is enabled
    (bazelbuild#7800)
  - `maven_jar` and `maven_server` now disallow using plain HTTP URLs
    without a specified checksum. If you are still using `maven_jar`,
    consider migrating to
    [`rules_jvm_external`](https://github.com/bazelbuild/rules_jvm_ext
    ernal) for transitive dependency management. See
    [bazelbuild#8607](bazelbuild#8607) for more
    information.
  - Added `sha256` and `sha256_src` attributes to `maven_jar`. Please
    consider migrating to SHA-256 as SHA-1 has been deemed
    cryptographically insecure ([https://shattered.io]()). Or, use
    [`rules_jvm_external`](https://github.com/bazelbuild/rules_jvm_ext
    ernal) to manage your transitive Maven dependencies with artifact
    pinning and SHA-256 verification support.
  - introducing per-target exec_properties
  - Bazel now supports ThinLTO builds on Linux for Clang versions >=
    6.0. ThinLTO can be enabled through --features=thin_lto
  - The Target.output_group field in Starlark is removed. Use
    OutputGroupInfo instead. See
    bazelbuild#7949 for details.
  - Make a number of parameters of Starlark builtin functions
    positional-only (as opposed to specifiable by keyword). See
    bazelbuild#8147 for details.
  - incompatible_skip_genfiles_symlink is enabled by default (bazelbuild#8651)
  - Change Pruned events will fire immediately after being checked.
  - --incompatible_remove_legacy_whole_archive has been flipped. See
    bazelbuild#7362 for more
    information

Important changes:

  - rule_test: fix Bazel 0.27 regression ("tags" attribute was
    ingored, bazelbuild#8723
  - Adds --incompatible_enable_execution_transition, which enables
    incremental migration of host attributes to exec attributes.
  - objc_proto_library rule has been deleted from Bazel.
  - repository_ctx.read is no longer restricted to files
        in the repository contructed.
  - tags 'no-remote', 'no-cache', 'no-remote-cache',
    'no-remote-exec', 'no-sandbox' are propagated now to the actions
    from targets when '--ncompatible_allow_tags_propagation' flag set
    to true. See bazelbuild#8830.
  - Adds flag
    --//tools/build_defs/pkg:incompatible_no_build_defs_pkg. This
    flag turns off the rules //tools/build_defs/pkg:{pkg_deb,
    pkg_rpm, pkg_tar}.
  - The Android NDK is now integrated with toolchains. To use them,
    pass the `--extra_toolchains=@androidndk//:all` flag or register
    them in your WORKSPACE with
    `register_toolchains("@androidndk//:all")`.
  - Stdout and stderr are checked to determine if output is going to a
    terminal. `--is_stderr_atty` is deprecated and `--isatty` is
    undeprecated.
  - --incompatible_load_proto_rules_from_bzl was added to forbid
    loading the native proto rules directly. See more on tracking
    issue bazelbuild#8922
  - Docker Sandbox now respects remote_default_platform_properties
  - pkg_deb, pkg_rpm & pkg_tar deprecation plan announced in the
    documentation.
  - The new java_tools release:
    * fixes bazelbuild#8614
    * exposes a new toolchain `@java_tools//:prebuilt_toolchain`
    which is using all the pre-built tools, including singlejar and
    ijar, even on remote execution. This toolchain should be used
    only when host and execution platform are the same, otherwise the
    binaries will not work on the execution platform.
  - java_common.compile supports specifying
    annotation_processor_additional_inputs and
    annotation_processor_additional_outputs for the Java compilation
    action for supporting annotation processors that consume or
    produce artifacts. Fixes bazelbuild#6415
  - There is now documentation on optimizing Android app build
    performance. Read it at
    https://docs.bazel.build/versions/0.29.0/android-build-performance
    .html
  - Execution log now respects --remote_default_platform_properties
  - Include a link to the relevant documenation on transitive Python
    version errors.
  - New incompatible flag
    --incompatible_disable_target_provider_fields removes the ability
    (in Starlark) to access a target's providers via the field syntax
    (for example, `ctx.attr.dep.my_provider`). The provider-key
    syntax should be used instead (for example,
    `ctx.attr.dep[MyProvider]`). See
    bazelbuild#9014 for details.
  - A new platform exec_properties is added to replace
    remote_execution_properties.
  - Added --incompatible_load_python_rules_from_bzl, which will be
    flipped in Bazel 1.0. See
    bazelbuild#9006.
  - add --break_build_on_parallel_dex2oat_failure to shortcut tests
    on dex2oat errors

     rule_test: apply "tags" to all rules in the macro

Incompatible changes:

  - Add --incompatible_enable_profile_by_default to enable the JSON
    profile by default.
  - The --incompatible_windows_style_arg_escaping flag is flipped to
    "true", and the "false" case unsupported. Bazel no longer accepts
    this flag.

Important changes:

  - Bazel now supports hiding compiler warnings for targets that
    you're not explicitly building (see
    https://docs.bazel.build/versions/master/user-manual.html#flag--au
    to_output_filter).
  - Flag `--incompatible_restrict_escape_sequences` is added. See
    bazelbuild#8380
  - The "info" command now supports the "starlark-semantics"
    argument, which outputs a representation of the effective Starlark
    semantics option values.
  - The `outputs` parameter of the `rule()` function is deprecated
    and attached to flag `--incompatible_no_rule_outputs_param`.
    Migrate rules to use `OutputGroupInfo` or `attr.output` instead.
    See bazelbuild#7977 for more info.
  - When `--incompatible_strict_action_env` is enabled, the default
    `PATH` now includes `/usr/local/bin`.
  - Turn on --experimental_build_setting_api by default for starlark
    build settings (see
    https://docs.bazel.build/versions/master/skylark/config.html#user-

    `@bazel_tools//tools/jdk:toolchain_java11` are now available to
    enable java 10, respectively java 11 language level support.
  - The `command` parameter of the `actions.run_shell()` function
    will be restricted to only accept strings (and not string
    sequences). This check is attached to flag
    `--incompatible_run_shell_command_string`. One may migrate by
    using the `arguments` parameter of `actions.run()` instead. See
    bazelbuild#5903 for more info.

    RELNOTES:
  - --incompatible_disable_nocopts flag has been added. See
    bazelbuild#8706 for details.
  - Fixed treatment of <dist:module /> tags in AndroidManifest.xml
  - Fixed asset precedence for android_binary rules with aapt2.
  - Bazel now officially supports running on CentOS 7.
  - The runtime dynamic libraries are no longer in default output
    group of cc_binary.
  - set the FDOBuildType as CSFDO for binaries built with
    --cs_fdo_absolute_path.
  - Bazel can now be bootstrapped and built on arm64 platforms
    without requiring any flags or patches.
  - Fixed treatment of AndroidManifest.xml attributes which contained
    XML escaping

    loading the native java rules directly. See more on tracking
    issue bazelbuild#8746
  - Turn on --experimental_build_setting_api by default for starlark
    build settings (see
    https://docs.bazel.build/versions/master/skylark/config.html#user-
