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.
  - Remove apple_watch1_extension and apple_watch_extension_binary
    rules. Users should be using the skylark watchos_application and
    watchos_extension rules.
    https://github.com/bazelbuild/rules_apple has details.
  - Windows: Wrapper-less CROSSTOOL becomes default now.
    set USE_MSVC_WRAPPER=1 if you still want to use wrapper script.
  - Ignore --glibc in the Android transition.
  - Remove --experimental_android_use_singlejar_for_multidex.
  - nocopts now also filter copts
  - 'strip' action is now configured via feature configuration
  - The Build Event Service (BES) client now properly supports
    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.
  - Removing a few unused objc_provider keys.
  - 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
    runfiles manifests.
  - Enable debug info for Java builds
  - Allow java_lite_proto_library in the deps of android rules.
  - .so files in APKs will be memory-page aligned when
    android_binary.nocompress_extensions contains ".so" and
    --experimental_android_use_nocompress_extensions_on_apk is
    specified.
  - Skylark providers can specify allowed fields and their
    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.
