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.

  files having changed.
• Top-level if statements are now forbidden.
• Java protos are compiled to Java 7 bytecode.

  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

  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

• J2ObjC version updated to 2.0.3.
• A new Java coverage implementation is available. Makes possible
  coverage for Skylark JVM rules.

  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.

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.

• 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.

0.5.0

Release 0.5.0 (2017-05-26)

Note: this release contains a bug in the compiler detection on macOS and
requires Xcode and the iOS tooling to be installed (corresponding issue #3063). If you had
Command Line Tools installed, you also need to switch to Xcode using
sudo xcode-select -s /Applications/Xcode.app/Contents/Developer.

• 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).
• 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.
• 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:" (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.

Classpath exception. Those installers should always be redistributed along with

  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.

0.4.4

Release 0.4.4 (2017-02-01)

Note: this release has 4 major regressions: #2526 #2473 #2490 and JDK-8154180. We are doing our best to issue a new bug-free release.

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
  .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
