Release 0.7.0 (2017-10-18)

Baseline: 5cc6246

Cherry picks:
   + e79a110:
     Windows,bootstrapping: fix build_windows_jni.sh

Incompatible changes:

  - The --output=location flag to 'bazel query' cannot be used with
    query expressions that involve the 'buildfiles' or 'loadfiles'
    operators. This also applies to 'genquery' rules.
  - Operators for equality, comparison, 'in' and 'not in' are no
    longer associative,
      e.g.  x < y < z  is now a syntax error. Before, it was parsed
    as:  (x < y) < z.
  - In strings, octal sequences greater than \377 are now forbidden
    (e.g. "\\600").
      Previously, Blaze had the same behavior as Python 2, where
    "\\450" == "\050".
  - Using tabulation for identation is now fobidden in .bzl files
  - `load` is now a language keyword, it cannot be used as an
    identifier
  - lvalues must have define at least one variable (i.e. we forbid
    `[] = f()`).
  - Fixed a bug whereby multiple load() statements could appear on
    the same line
  - -extra_checks:off is no longer supported; use
    -XepDisableAllChecks instead
  - java_common.java_toolchain_attr is removed. Depend on the
    java_toolchain_alias() rule to accomplish the same thing.
  - cc_common.cc_toolchain_attr and java_common.java_runtime_attr are
    not supported anymore and were replaced with the
    cc_toolchain_alias() and java_runtime_alias() rules.
  - Noop flag --deprecated_generate_xcode_project deleted.
  - Objects in Skylark are converted to strings in a more descriptive
    and less harmful way (they don't leak information that shouldn't
    be accessed by Skylark code, e.g. nondeterministic memory addresses
    of objects).
  - `set` is deprecated in BUILD and .bzl files, please use `depset`
    instead. Ordering names have also been changed, please use "default",
    "postorder", "preorder", and "topological" instead of "stable",
    "compile", "naive_link", and "link" correspondingly.
  - Integer overflow (on signed 32 bit numbers) in BUILD/bzl files is
    an error.
  - Keyword-only syntax in a function definition is now forbidden
      e.g. `def foo(a, *, b)` or `def foo(a, *b, c)`
  - --incompatible_comprehension_variables_do_not_leak defaults to
    "true."
      Iteration variable becomes inaccessible after a list/dict
    comprehension.
  - @bazel_tools//tools/build_defs/docker:docker.bzl is no longer
    available, please see https://github.com/bazelbuild/rules_docker.

New features:

  - Zipped LLVM profiles are now supported.
  - LIPO maps to ThinLTO for LLVM builds.
  - Change to handle LLVM FDO zipped profile contents correctly.
  - Do not disable fully dynamic linking with ThinLTO when invoked
    via LIPO options.
  - There is now a 'siblings' query function. See the query
    documentation for more details.
  - Added the print_action command, which outputs the
    actions needed to build a given target in the form of an
    ExtraActionSummary proto in text format.
  - android_binary now supports proguard_apply_dictionary to specify
    a custom dictionary to use for choosing names to obfuscate
    classes and members to.

Important changes:

  - Windows: bazel clean --expunge works
  - First argument of 'load' should be a label. Path syntax is
    deprecated (label should start with '//' or ':').
  - Octal prefix '0' is deprecated in favor of '0o' (use 0o777
    instead of 0777).
  - The extension_safe attribute of apple_binary no longer validates
    transitive dependencies are compiled against extension_safe APIs.
  - Parentheses around the tuple are now mandatory in [a for b in c
    if 1, 2]
  - Adjust the thresholds for --test_verbose_timeout_warnings so that
    it can recommending timeout increases and won't recommend
    timeouts that are too close to the actual timeout.
  - Iterating on a `depset` object is deprecated. If you need an
    iterable, call the `.to_list()` method first.
  - Bazel now uses tools from action_configs in Crosstool by default
    (as oposed to using top level tools).
  - Incremental dexing errors on combination of --multidex=off and
    either --main-dex-list or --minimal-main-dex.
  - When using the dictionary literal syntax, it is now an error to
    have duplicated keys (e.g.  {'ab': 3, 'ab': 5}).
  - New property on android_sdk: aapt2
      Choose the version of aapt on android_binary
  - Add idl_preprocessed attribute to android_library, so that
    preprocessed aidl files can be passed to android_library for
    compiling
  - Bazel's remote_worker backend for remote execution supports
    sandboxing on Linux now. Check
    https://github.com/bazelbuild/bazel/blob/master/src/tools/remote_w
    orker/README.md for details.
  - Allows flags that expand to take values.
  - Make querying attributes formed by selector lists of list types
    more efficient by no longer listing every possible combination of
    attribute value but by more compactly storing the possible values
    of the list.
  - writing build events to a file is no longer experimental
  - set --rewrite_calls_to_long_compare to false by default.
  - ObjC and C++ coverage feature is unified under name 'coverage'
  - Enable --incremental_dexing for Android builds by default. Note
    that some dexopts are incompatible with incremental dexing,
    including --force-jumbo.
  - Evaluation will soon use checked arithmetics and throw an error
    instead of overflow/underflow.
  - Implicit iteration in the CROSSTOOL has been removed, use
    explicit 'iterate_over' message.
  - Add option for Android specific grte_top
  - Crosstool patches are only applied if the toolchain doesn't define
    'no_legacy_features' feature.
  - 'platform_type' is now a mandatory attribute on apple_binary and
    apple_static_library rules.
    If this change breaks your build, feel free to add platform_type
    = 'ios' to any apple_binary and apple_static_library
    targets in your project, as this was the previous default
    behavior.
  - Remove apple_watch2_extension build rule. Users should be using
    the skylark watchos_application and watchos_extension rules.
    https://github.com/bazelbuild/rules_apple has details.
  - Check stderr to detect if connected to a terminal.  Deprecate
    --isatty.
  - Commands that shut down the server (like "shutdown") now ensure
    that the server process has terminated before the client process
    terminates.

    rules. Users should be using the skylark watchos_application and
    watchos_extension rules.

    Google Applicaton Default Credentials.
  - Flags from action_config get added first to the command line
    first, before the flags from features.
  - update dexing tools to Android SDK 26.0.1
  - Bazel Android support now requires build-tools 26.0.1 or later.
  - `bazel info output_path` no longer relies on the root directory
    filename being equal to the workspace name.
  - The `print` function now prints debug messages instead of
    warnings.
  - speedup of incremental dexing tools
  - --announce_rc now controls whether bazelrc startup options are
    printed to stderr.

  - Improved logging when workers have to be restarted due to its
    files having changed.
  - Top-level `if` statements are now forbidden.
  - Java protos are compiled to Java 7 bytecode.
  - All Android builds now use the desugar tool to support some Java
    8 features by default. To disable, use the --nodesugar_for_android flag.
  - Skylark-related options may now appear as "common" command
    options in the .bazelrc
  - Python is now required to build bazel.
  - New --build_runfile_manifests flag controls production of

    documentation.
  - Support ctx.actions.args() for more efficient Skylark command
    line construction.
  - The remote HTTP/1.1 caching client (--remote_rest_cache) now
    distinquishes between action cache and CAS. The request URL for
    the action cache is prefixed with 'ac' and the URL for the CAS
    is prefixed with 'cas'.
  - `JavaInfo` is a preferred alias to `java_common.provider`.
  - J2ObjC version updated to 2.0.3.
  - A new Java coverage implementation is available. Makes possible
    coverage for Skylark JVM rules.
  - Make proguard_apply_dictionary also apply to class and package
    obfuscation, not just class members.
  - android_binary.nocompress_extensions now applies to all files in
    the APK, not just resources and assets.
  - The apple_genrule rule that is distributed with Bazel has been
    deleted. Users who wish to use genrules with Xcode's
    DEVELOPER_DIR set should use the rules in
    https://github.com/bazelbuild/rules_apple instead.
  - The swift_library rule that is distributed with Bazel has been
    deleted. Users who wish to compile Swift should use the rules in
    https://github.com/bazelbuild/rules_apple instead.
  - The Build Event Protocol's File.uri field is now properly
    encoded according to RFC2396.
  - Deprecated: Using the android_library.deps attribute to
    implicitly export targets to dependent rules. If your code is
    using this feature, Bazel will raise a warning. To fix, please
    use android_library.exports to explicitly specify exported
    targets. Run with
    --experimental_allow_android_library_deps_without_srcs=false to
    ensure forward compatibility when this feature is removed in a
    future release.
  - java_common.create_provider is now supported with creating ijars
    by default. This introduces incompatibilities for existing users.
    Please set use_ijar=False if you don't want to use ijars.
  - Tests can now write files to TEST_UNDECLARED_OUTPUTS_DIR and
    TEST_UNDECLARED_OUTPUTS_ANNOTATIONS_DIR and these will be
    reflected under bazel-testlogs.
  - remove unused --host_incremental_dexing flag
  - Stop using --undefined dynamic_lookup in Apple links. Enables
    unresolved symbol errors.
  - All test output files included for cached, uncached, and multiple
    attempt tests.
  - Android rules no longer restrict the manifest file to be named
    "AndroidManifest.xml".
  - Boolean flag values will now get normalized to 1 or 0 in
    canonicalize-flags output.
  - added experimental --use_new_category_enum to the help command to
    output options grouped by the new type of category.
  - Expose output jars and jdeps in java_common.provider, when
    available.
  - android_library targets are no longer allowed to use deps to
    export targets implicitly; please use android_library.exports
    instead.
  - New depset API
  - apple_binary and apple_static_library no longer support
    compilation attributes such as 'srcs'. If this breaks any
    existing targets, you may migrate all such attributes to a new
    objc_library target and depend on that objc_library target via
    the 'deps' attribute of apple_binary or apple_static_library.

Incompatible changes:

  - Blaze no longer generates xcode projects. Use tulsi.bazel.build
    instead.

Important changes:

  - Keyword-only syntax in a function definition is deprecated
      (e.g. `def foo(a, *, b)` or `def foo(a, *b, c)`) and will be
    removed in the future.
  - Attempting to build an Android target without setting up
    android_sdk_repository will now produce a helpful error message.
  - Adds a sha256 attribute to git_repository and new_git_repository.
    This can only be used if the remote is a public GitHub
    repository. It forces
    Bazel to download the repository as a tarball, which will often
    be faster and
    more robust than cloning it.
  - Sandboxing is now enabled by default on FreeBSD (via
    processwrapper-sandbox).
  - android_test may use manifest placeholders with 'manifest_merger
    = "android"'.
  - load() statements should be called at the top of .bzl files,
    before any
      other statement. This convention will be enforced in the future.
  - Effectively remove sysroot from CppConfiguration and allow it to
    use select statements.
  - proto_library.strict_proto_deps no longer exists.
  - Flag --explicit_jre_deps is now a noop.
  - The 'legacy' Android manifest merger is deprecated. Please
    upgrade to the 'android' manifest merger, which is the same
    merger used by Gradle.
    https://developer.android.com/studio/build/manifest-merge.html
  - Using $(CC_FLAGS) in a GenRule adds a dependency to the c++
    toolchain
  - add one-version enforcement to android_local_test
  - Skylark support (apple_common.dotted_version(string)) for
    building DottedVersion objects to interface with native apple
    rules
  - CC_FLAGS can be defined using 'cc-flags-make-variable' action_config in
    CROSSTOOL
  - ios_framework native rule has been removed. This rule had been
    essentially broken for several months now; users should be using
    the skylark ios framework rule.
    https://github.com/bazelbuild/rules_apple has details.
  - Clean command no longer uses boolean values for --async,
    --expunge, and --expunge_async options.
  - Partially fixes external J2ObjC support.
  - '--aspects' can occur more than once on the command line.
  - --no_ prefix no longer recognized.
  - Use action_config in crosstool for static library archiving,
    remove ar_flag.
  - Added a new flag --sandbox_writable_path, which asks the sandbox
    to
    make an existing directory writable when running actions.
  - bazel test now also computes a default instrumentation filter if
    --collect_code_coverage is enabled
  - n/na
  - In .bzl files, top-level `if` statements are deprecated and will
    be forbidden
      in the future. Move them in a function body instead (or use a
    conditional
      expression instead: `x if condition else y`).
  - ios_device and ios_test are deprecated. Please use the new testing
    rules in https://github.com/bazelbuild/rules_apple instead.
  - bazel query --output package now displays packages from external
    repository with the format "@reponame//package". Packages in the
    main repository continue to have the format "package".
  - ctx.expand_make_variables is deprecated.
  - Bazel posts links to the CAS to the BEP if remote caching /
    execution is enabled
  - `bazel info execution_root` returns the corrrect directory name
    for the execution root.

   + 0f0ccc4:
     Escape % in strings that will appear in Crosstool
   + 3b08f77:
     Adding feature for linking C Run-Time library on Windows

Incompatible changes:

  - Bazel's Linux sandbox no longer mounts an empty tmpfs on /tmp,
    instead the existing /tmp is mounted read-write. If you prefer
    to have a tmpfs on /tmp for sandboxed actions for increased
    hermeticity, please use the flag --sandbox_tmpfs_path=/tmp.
  - Converting artifacts to strings and printing them now return
    "File" instead of "Artifact" to be consistent with the type name.
  - The return type of depset.to_list() is now a list rather than a
    frozen list. (Modifying the list has no effect on the depset.)
  - Bazel now prints logs in single lines to java.log
  - --use_dash, --dash_url and --dash_secret are removed.
  - Remote repositories must define any remote repositories they
    themselves use (e.g., if @x//:foo depends on @y//:bar, @y must be
    defined
    in @x's WORKSPACE file).
  - Remote repositories must define any remote repositories they
    themselves use (e.g., if @x//:foo depends on @y//:bar, @y must be
    defined
    in @x's WORKSPACE file).
  - objc_xcodeproj has been removed, use tulsi.bazel.build instead.

New features:

  - If grte_top is a label, it can now follow non-configurable
    redirects.
  - Optional coverage_files attribute to cc_toolchain
  - "query --output=build" now includes select()s
  - Raw LLVM profiles are now supported.

Important changes:

  - Automatically generate Proguard mapping when resource shrinking
    and Proguard are enabled.
  - New rules in Bazel: proto_library, java_lite_proto_library,
    java_proto_library and cc_proto_library
  - Activate the "dead_strip" feature if objc binary stripping is
    enabled.
  - More stable naming scheme for lambda classes in desugared android
    code
  - Convert --use_action_cache to a regular option
  - Per-architecture dSYM binaries are now propagated by
    apple_binary's AppleDebugOutputsProvider.
  - Avoid factory methods when desugaring stateless lambdas for
    Android
  - desugar calls to Objects.requireNonNull(Object o) with
    o.getClass() for android
  - Add an --copy_bridges_from_classpath argument to android
    desugaring tool
  - Change how desugar finds desugared classes to have it working on
    Windows
  - Evaluation of commands on TargetsBelowDirectory patterns
    (e.g. //foo/...) matching packages that fail to load now report
    more
    detailed error messages in keep_going mode.
  - Allow to have several inputs and outputs
  - Repository context's execute() function can print stdout/stderr
    while running. To enable, pass quiet=False.
  - Bazel can now be built with a bundled version of the OpenJDK.
    This makes it possible to use Bazel on systems without a JDK, or
    where
    the installed JDK is too old.
  - The --jobs flag now defaults to "auto", which causes Bazel to
    use a reasonable degree of parallelism based on the local
    machine's
    capacity.
  - Bazel benchmark (perf.bazel.build) supports Java and Cpp targets.
  - no factory methods generated for lambda expressions on android
  - The Linux sandbox no longer changes the user to 'nobody' by
    default, instead the current user is used as is. The old behavior
    can be
    restored via the --sandbox_fake_username flag.
  - /tmp and /dev/shm are now writable by default inside the
    Linux sandbox.
  - Bazel can now use the process-wrapper + symlink tree based
    sandbox implementation in FreeBSD.
  - turn on --experimental_incremental_dexing_error_on_missed_jars by
    default.
  - All android_binarys are now signed with both Apk Signature V1 and
    V2. See https://source.android.com/security/apksigning/v2.html
    for more details.
  - Windows MSVC wrappers: Not filtering warning messages anymore,
    use --copt=-w and --host_copt=-w to suppress them.
  - A downloader bug was fixed that prevented RFC 7233 Range
    connection resumes from working with certain HTTP servers
  - Introduces experimental android_device rule for configuring and
    launching Android emulators.
  - For boolean flags, setting them to false using --no_<flag_name>
    is deprecated. Use --no<flag_name> without the underscore, or
    --<flag_name>=false instead.
  - Add --experimental_android_compress_java_resources flag to store
    java
    resources as compressed inside the APK.
  - Removed --experimental_use_jack_for_dexing and libname.jack
    output of
    android_library.
  - blaze canonicalize-flags now takes a --show_warnings flag
  - Changing --invocation_policy will no longer force a server
    restart.
  - Bazel now supports Android NDK14.
  - android_binary multidex should now work without additional flags.
  - Use action_config in crosstool for static library archiving,
    remove ar_flag.
  - new option for bazel canonicalize-flags, --canonicalize_policy
  - Use action_config in crosstool for static library archiving,
    remove ar_flag.
  - android_library exports_manifest now defaults to True.
  - Fix select condition intersections.
  - Adds a --override_repository option that takes a repository
    name and path. This forces Bazel to use the directory at that path
    for the repository. Example usage:
    `--override_repository=foo=/home/user/gitroot/foo`.
  - fix idempotency issue with desugaring lambdas in interface
    initializers for android
  - --experimental_android_use_singlejar_for_multidex is now a no-op
    and will eventually be removed.
  - Every local_repository now requires a WORKSPACE file.
  - Remove jack and jill attributes of the android_sdk rule.
  - Add Skylark stubs needed to remove sysroot from CppConfiguration.
  - Desugar try-with-resources so that this language feature is
    available
    to deveces with API level under 19.
  - The flag --worker_max_retries was removed. The
    WorkerSpawnStrategy no longer retries execution of failed Spawns,
    the reason being that this just masks compiler bugs and isn't
    done for any other execution strategy either.
  - Bazel will no longer gracefully restart workers that crashed /
    quit, instead this triggers a build failure.
  - All java resources are now compressed in android_binary APKs by
    default.
  - All java resources are now compressed in android_binary APKs by
    default.
  - android_ndk_repository now creates a cc_library
    (@androidndk//:cpufeatures) for the cpufeatures library that is
    bundled in the Android NDK. See
    https://developer.android.com/ndk/guides/cpu-features.html for
    more details.
  - 'output_groups' and 'instrumented_files' cannot be specified in
    DefaultInfo.
  - You can increase the CPU reservation for tests by adding a
    "cpu:<n>" (e.g. "cpu:4" for four cores) tag to their rule in a
    BUILD file. This can be used if tests would otherwise overwhelm
    your system if there's too much parallelism.
  - Deprecate use_singlejar_for_proguard_libraryjars and force
    behavior to always on.

   + b6ea0d3:
     Add the appropriate cxx_builtin_include_directory entries for
     clang to the Android NDK crosstool created by
     android_ndk_repository.

Incompatible changes:

  - Depsets (former sets) are converted to strings as "depset(...)"
    instead of
    "set(...)".
  - Using --symlink_prefix is now applied to the output
    symlink (e.g. bazel-out) and the exec root symlink (e.g.
    bazel-workspace).
  - Bazel now uses the test's PATH for commands specified as
        --run_under; this can affect users who explicitly set PATH to
    a more
        restrictive value than the default, which is to forward the
    local PATH
  - It's not allowed anymore to compare objects of different types
    (i.e. a string to an integer) and objects for which comparison
    rules are not
    defined (i.e. a dict to another dict) using order operators.

New features:

  - environ parameter to the repository_rule function let
    defines a list of environment variables for which a change of
    value
    will trigger a repository refetching.

Important changes:

  - android_ndk_repository now supports Android NDK R13.
  - Android resource shrinking is now available for android_binary
    rules. To enable, set the attribute 'shrink_resources = 1'. See
    https://bazel.build/versions/master/docs/be/android.html#android_b
    inary.shrink_resources.
  - resolve_command/action's input_manifest return/parameter is now
    list
  - For increased compatibility with environments where UTS
    namespaces are not available, the Linux sandbox no longer hides
    the hostname of the local machine by default. Use
    --sandbox_fake_hostname to re-enable this feature.
  - proto_library: alias libraries produce empty files for descriptor
    sets.
  - Adds pkg_rpm rule for generating RPM packages.
  - Allow CROSSTOOL files to have linker flags specific to static
    shared libraries.
  - Make it mandatory for Java test suites in bazel codebase, to
    contain at least one test.
  - Support for Java 8 lambdas, method references, type annotations
    and repeated annotations in Android builds with
    --experimental_desugar_for_android.
  - Removed .xcodeproj automatic output from objc rules. It can still
    be generated by requesting it explicitly on the command line.
  - Flips --explicit_jre_deps flag on by default.
  - Activate the "dbg", "fastbuild", and "opt" features in the objc
    CROSSTOOL.
  - Remove support for configuring JDKs with filegroups; use
    java_runtime and java_runtime_suite instead
  - android_ndk_repository api_level attribute is now optional. If not
    specified, the highest api level in the ndk/platforms directory
    is used.

Release 0.4.4 (2017-02-01)

Baseline: 4bf8cc3

Cherry picks:
   + ef1c6fd: msvc_tools.py.tpl: Change default runtime library to
              static

Incompatible changes:

  - Only targets with public visibility can be bound to something in
    //external: .
  - The deprecated -x startup option has been removed.
  - docker_build: change the repository names embedded by
    docker_build. You can revert to the old behavior by setting
    legacy_repository_naming=True.
  - The string methods strip(), lstrip(), and rstrip() now
    by default remove the same whitespace characters as Python 3
    does, and accept
    None as an argument.
  - Deprecated globals HOST_CFG and DATA_CFG are removed. Use strings
    "host" and "data" instead.
  - repository_ctx environment is now affected by --action_env flag
    (value from the
    client environment will be replaced by value given on the command
    line through --action_env).
  - All executable labels must also have a cfg parameter specified.
  - Removed the cmd_helper.template function.
      The function was equivalent to:
        def template(items, template):
          return [template.format(path = i.path, short_path =
    i.short_path)
                    for i in items]
  - Tuples that end with a trailing comma must now be inside parens,
      e.g. (1,) instead of 1,
  - The traversal orders for depsets have been renamed. The old names
    are deprecated and will be removed in the future. New names:
    "stable" -> "default", "compile" -> "postorder", "link" ->
    "topological", "naive_link" -> "preorder".

New features:

  - Skylark: you can now multiply a list by an integer to get the
    concatenation of N copies of this list, e.g. [a,b] * 3 =
    [a,b,a,b,a,b]
  - Allow Android aidl tool to add a jar to the program's classpath,
    such as if needed to support generated sources.
  - Add transitive proguard_specs when android_sdk.aidl_lib is
    specified
  - Windows: "/dev/null" is now a supported path, e.g.
    --bazelrc=/dev/null now works

Important changes:

  - Bazel Android builds use the apksigner tool from the Android SDK
    build-tools. Bazel Android builds now require build-tools version
    24.0.3 or
    later.
  - Android SDK external bindings for support libraries, e.g.
    //external:android/appcompat_v4, are removed because the support
    library JARs that they referenced no longer ship with the Android
    SDK.
  - aar_import rule is now documented.
  - An IE bug was fixed in repository_ctx.download_and_extract
  - Update "-I" to "-isystem" in documentation to reflect current
    behavior.
  - android_sdk_repository build_tools_version is now optional. The
    highest installed build-tools will be used if none is specified.
  - New flag --sandbox_add_mount_pair to specify customized
    source:target path pairs to bind mount inside the sandbox.
  - expose proto_library descriptor set to skylark via
    <dep>.proto.descriptor_set
  - The `set` constructor is deprecated in favor of `depset`
  - Autodetect gold linker in cc_configure.bzl
  - Remove build flag --experimental_j2objc_annotation_processing. It
    is on by default now.
  - Set clang's -mwatchos-version-min correctly using the value of
    --watchos_minimum_os, not --watchos_sdk_version.
  - singlejar can now create jar files larger than 4GB.
  - android_sdk_repository and android_ndk_repository now read
    $ANDROID_HOME and $ANDROID_NDK_HOME if the path attribute is not
    set.
  - Removed broken api levels 3, 4 and 5 from Android NDK 12.
  - Default --android_dynamic_mode to off.
  - android_sdk_repository no longer requires api_level. If one is
    not specified, the highest android platform installed will be
    used. Furthermore, android_sdk's are created for all android
    platforms installed and can be specified with the --android_sdk
    flag.
  - To iterate over or test for membership in a set, prefer using the
    new to_list() method. E.g., "for x in myset.to_list():", or
    "print(x in myset.to_list())". Iteration/membership-test on the
    raw set itself is deprecated.
  - Remove support for --javawarn; use e.g. --javacopt=-Xlint:all
    instead
