0.3.2

Release 0.3.2 (2016-10-07)

Baseline: 023a7bd

Cherry picks:

• bebbbe5: Fix dependency on libtool's helper script
  make_hashed_objlist.py.
• 8a0d45f: Add the version information to the bazel.exe file
• 2bc0939: Allow new_ rules to overwrited BUILD files in
  downloaded repos
• c5545fd: Rollback of commit
  96d4628.
• eb87208: Make cc_configure on Windows more robust
• c30432c: Fix cc_configure on Windows
• 95b16a8: sandbox: Replace the error-prone lazy cleanup of
  sandbox directories by a simple synchronous cleanup.
• e898023: Fix #1849: Sandboxing on OS X should be turned off by
  default for 0.3.2.
• ffdc05d: Add action_config and feature for linking on Windows

Incompatible changes:

• If you maintain a rule that uses persistent workers, you'll have
  to specify execution_requirements={"supports-workers": 1} in the
  ctx.action that intends to run a tool with workers. The
  WorkerSpawnStrategy will alert you with a warning message if you
  forget to make this change and fallback to non-worker based
  execution.
• It is now an error to include a precompiled library (.a, .lo, .so)
  in a cc_library which would generate a library with the same name
  (e.g., libfoo.so in cc_library foo) if that library also contains
  other linkable
  sources.
• The main repository's execution root is under the main
  repository's workspace name, not the source directory's basename.
  This shouldn't
  have any effect on most builds, but it's possible it could break
  someone doing
  weird things with paths in actions.
• Blaze doesn't support Unix domain sockets for communication
  between its client and server anymore. Therefore, the
  --command_port command line argument doesn't accept -1 as a valid
  value anymore.
• Skylark: It is an error to shadow a global variable with a local
  variable after the global has already been accessed in the
  function.
• bin_dir and genfiles_dir are now properties of ctx, not
  configuration. That is, to access the bin or genfiles directory
  from a
  Skylark rule, use ctx.bin_dir or ctx.genfiles_dir (not
  ctx.configuration.{bin,genfiles}_dir). At the moment, you can
  access
  {bin,genfiles}_dir from either, but the ctx.configuration version
  will
  stop working in a future release.
• filegroup-based C++ toolchains are not supported anymore.
  --*_crosstool_top options must always point to a
  cc_toolchain_suite rule (or an alias of one).
• repository_ctx.{download,download_and_extract,execute} API now use
  named parameters for optional parameters and no
  longer uses argument
  type to distinguished between arguments
  (executable attribute name
  must be specified when preceding optional
  arguments are missing).

New features:

• print and fail are now available in BUILD files.

Important changes:

• Added @bazel_tools//tools/build_defs/repo/git.bzl as a Skylark
  rule for Git repositories.
• Added @bazel_tools//tools/build_defs/repo/maven_rules.bzl as a
  Skylark rule for Maven repositories.
• Add global hash() function for strings (only)
• Improve Android split transition handling.
• Removes exports_manifest attribute from android_binary rule.
• java_proto_library: control strict-deps through a rule-level and
  a package-level attribute.
• Persistent workers are now used by default for Java compilation
  in Bazel, which should speed up your Java builds by ~4x. You can
  switch back to the old behavior via --strategy=Javac=standalone.

  for more details.
• objc_* rules can now depend on any target that returns an "objc"
  provider.
• Adds support for NDK12 to android_ndk_repository rule in Bazel.
• Test targets can disable the JUnit4 test security manager via a
  property.
• Disable the Android split transition if --android_cpu and
  fat_apk_cpu are both empty.
• New sandboxing implementation for Linux in which all actions run
  in a separate execroot that contains input files as symlinks back
  to the originals in the workspace. The running action now has
  read-write access to its execroot and /tmp only and can no longer
  write in arbitrary other places in the file system.
• Add worker support to single jar.
• Invoke source jar action as a worker.
• Sandboxed builds allow network access for builds by default.
  Tests will still be run without networking, unless
  "requires-network" is specified as a tag.
• Add path.realpath() method for Skylark repositories.
• On Mac devices, detect locally installed versions of xcode to:
  1. Use a sensible default if xcode is required but
     --xcode_version is unspecified.
  2. Use sensible default iOS SDK version for the targeted version
     of xcode if ios_sdk_version is unspecified.
• Emacs' [C-x `], a.k.a. next-error, works again in emacsen >= 25.1
• swift_library can be used to build watchOS apps.
• Exposes the is_device field on Apple platform objects and adds
  the apple_common.platform_type(name) method to retrieve a
  platform_type value that can be passed to methods like the Apple
  fragment's multi_arch_platform.
• Move Skylark git_repository rules to git.bzl
• Add support for aspects to attr.label() attributes
• Global varaiables HOST_CFG and DATA_CFG are deprecated in favor
  of strings "host"
  and "data.
  Argument cfg = "host" or cfg = "data" is mandatory if
  executable = True is provided for a label.
• The deprecation attribute of all rules now causes warnings
  to be printed when other targets depend on a target with that
  attribute set.
• Change default of --[no]instrument_test_targets to false, change
  default --instrumentation_filter (which previously tried to
  exclude test targets by heuristic) to only exclude targets in
  javatests.
• Remove deprecated absolute paths in blaze IDE artifacts
• When using android_binary.manifest_merger="android" the merger
  produces a summary log next to the merged manifest artifact.
• Allow different default mallocs per configuration.
