0.4.2

Release 0.4.2 (2016-12-02)

Baseline: 6331a94

Cherry picks:

• 7b835d9: Do not patch WORKSPACE in the release process

Incompatible changes:

• Callback functions in Skylark no longer support the cfg
  parameter. This is a cleanup and only affects the signatures of
  callbacks, since the parameter hasn't been set since September
  2016.

Important changes:

• Alias proto_library's produce a descriptor set that contains all
  srcs of its dependencies.
• proto_library supports strict proto deps.
• Top level @AndroidSDK support library targets have been replaced
  by @androidsdk//:- for Android
  SDK Support and Google Play Services libraries.

0.4.1

Release 0.4.1 (2016-11-21)

Baseline: 2a26c3c

Cherry picks:

• a79581e: Add gpu compile support to MSVC wrapper script

New features:

• android_library now has a "exported_plugins" attribute just like
  java_library
• Use --strict_system_includes to apply hdrs_check=strict also to
  cc_library.includes, even if sandboxing is disabled.
• Bazel on Windows: java_binary can now be the executable of
  Skylark rule actions (ctx.action's executable argument)
• Packages are defined in BUILD.bazel as well as BUILD files.

Important changes:

• getattr()'s 3-arg form no longer raises an error when the
  retrieved field is a built-in method.
• --apk_signing_method default changed to v1. Android APKs are now
  signed with the new ApkSignerTool by default.
• New rule: proto_lang_toolchain(), to support LANG_proto_library
  rules on multiple platforms.
• Fix for Android clang++ std::stack segfault on 32bit x86. See
  https://code.google.com/p/android/issues/detail?id=220159
• Default android_manifest_merger is now "android" which uses the
  official Android manifest merger.
  http://tools.android.com/tech-docs/new-build-system/user-guide/man
  ifest-merger
• Do not propagate aspect to its own attributes when using '*'.
• Comparing sets (if set1 < set2:) is not allowed anymore in
  Skylark because it didn't work correctly anyway.
• When --experimental_extra_action_top_level_only, Bazel reports
  extra-actions for actions registered by Aspects injected by a
  top-level rule (approximately).
• Blacklists for proto_lang_toolchain() no longer have to be
  proto_library's.
• Extra actions now contain aspect-related information.
• Fix slicing bug where "abc"[:-4:-1] would give wrong answer

0.4.0

Release 0.4.0 (2016-10-26)

Baseline: 088bbc6

Cherry picks:

• b01160c: Stamp Windows release.
• 2d6736e: Add --no-tty for gpg signing
• 9b1dfb8: Remove .sig file before gpg signing
• 81aede1: Reimplement whole archive on Windows

Incompatible changes:

• Skylark: updating list/dicts while they are being looped over is not
  allowed. Use an explicit copy if needed ("for x in list(mylist):").
• Bazel now uses the --cpu flag to look up Jvms; it falls back
  to "default" if it can't find a Jvm matching the CPU value.
• --command_port=-1 to use AF_UNIX for client/server communications
  is not supported anymore.
• Sandboxed actions can access the network by default, unless their
  target has a "block-network" tag.

New features:

• Files now have an "extension" property in Skylark.

Important changes:

• Added a new flag --sandbox_tmpfs_path, which asks the sandbox to
  mount an empty, writable directory at a specified path when
  running actions. (Supported on Linux only for now.)
• Update protoc-3.0.0-mingw.exe to a working (statically linked)
  binary
• apple_static_library rule to create multi-architecture static
  archive files from Objc/C++/Swift dependencies on apple platforms
• JS: Add support for localization with closure managed rules.
• Create a flag --android_dynamic_mode to turn off dynamic mode
  during the Android split transition.
• Darwin sandboxing is default.
• Remove flag --experimental_zip_tree_artifact from j2objc Java
  annotation processing support.
• A few functions are added to BUILD files for consistency (hash,
  dir,
  hasattr, getattr) with .bzl files, although they are not very
  useful.
• --watchfs is now a command option; the startup option of the same
  name is deprecated. I.e., use bazel build --watchfs, not
  blaze --watchfs
  build.

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.
  Check out http://www.bazel.io/blog/2015/12/10/java-workers.html
  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.

0.3.1

Release 0.3.1 (2016-07-29)

Baseline: 792a9d6

Cherry picks:

• 25e5995: Rollback of commit
  a277033.
• 2479405: Fix NPE with unset maven_jar sha1
• 3cf2126: Rewrite the extra action info files if the data within
  them changes.
• 5a9c6b4: JavaBuilder: Reintroduce the -extra_checks flag.

Incompatible changes:

• Removed predefined Python variable "generic_cpu".
• Skylark rules: if you set "outputs" or an attribute to a
  function, this function must now list its required attributes as
  parameters (instead of an attribute map).
• The host_platform and target_platform entries are not written to
  the master log anymore.
• Bazel requires Hazelcast 3.6 or higher now for remote execution
  support, because we upgraded our client library and the protocol
  it uses is incompatible with older versions.

New features:

• LIPO context (--lipo_context) can now also be a cc_test (in
  addition to cc_binary)

Important changes:

• If --android_crosstool_top is set, native code compiled for
  android will always use --android_compiler and not --compiler in
  choosing the crosstool toolchain, and will use --android_cpu if
  --fat_apk_cpu is not set.
• Add --instrument_test_targets option.
• apple_binary supports a new platform_type attribute, which, if
  set to "watchos", will build dependencies for Apple's watchOS2.
• objc_binary now supports late-loaded dynamic frameworks.
• Native Swift rules no longer pull in module maps unconditionally.
  Use --experimental_objc_enable_module_maps for that.
• Merged manifests are guaranteed to have the application element
  as the last child of the manifest element as required by Android
  N.
• The Android manifest merger is now available as an option for
  android_binary rules. The merger will honor tools annotations in
  AndroidManifest.xml and will perform placeholder substitutions
  using the values specified in android_binary.manifest_values. The
  merger may be selected by setting the manifest_merger attribute
  on android_binary.
• The progress message would not clear packages that need to be
  loaded twice.
• Remove warning for high value of --jobs.
• Use the correct build configuration for shared native deps during
  Android split transitions.
• When building ObjectiveC++, pass the flag -std=gnu++11.
• use xcrun simctl instead of iossim to launch the app for "blaze
  run".
• Glob arguments 'exclude' and 'exclude_directories' must be named
• Bazel no longer regards an empty file as changed if its mtime has
  changed.

0.3.0

Release 0.3.0 (2016-06-10)

Baseline: a9301fa

Cherry picks:

• ff30a73: Turn --legacy_external_runfiles back on by default
• aeee3b8: Fix delete[] warning on fsevents.cc

Incompatible changes:

• The --cwarn command line option is not supported anymore. Use
  --copt instead.

New features:

• On OSX, --watchfs now uses FsEvents to be notified of changes
  from the filesystem (previously, this flag had no effect on OS X).
• add support for the '-=', '*=', '/=', and'%=' operators to
  skylark. Notably, we do not support '|=' because the semantics
  of skylark sets are sufficiently different from python sets.

Important changes:

• Use singular form when appropriate in blaze's test result summary
  message.
• Added supported for Android NDK revision 11
• --objc_generate_debug_symbols is now deprecated.
• swift_library now generates an Objective-C header for its @objc
  interfaces.
• new_objc_provider can now set the USES_SWIFT flag.
• objc_framework now supports dynamic frameworks.
• Symlinks in zip files are now unzipped correctly by http_archive,
  download_and_extract, etc.
• swift_library is now able to import framework rules such as
  objc_framework.
• Adds "jre_deps" attribute to j2objc_library.
• Release apple_binary rule, for creating multi-architecture
  ("fat") objc/cc binaries and libraries, targeting ios platforms.
• Aspects documentation added.
• The --ues_isystem_for_includes command line option is not
  supported anymore.
• global function 'provider' is removed from .bzl files. Providers
  can only be accessed through fields in a 'target' object.

Classpath exception. Those installers should always be redistributed along with
the source code.

0.2.3

Release 0.2.3 (2016-05-10)

Baseline: 5a2dd7a

Incompatible changes:

• All repositories are now directly under the x.runfiles directory
  in the runfiles tree (previously, external repositories were at
  x.runfiles/main-repo/external/other-repo. This simplifies
  handling remote repository runfiles considerably, but will break
  existing references to external repository runfiles.
  Furthermore, if a Bazel project does not provide a workspace name
  in the WORKSPACE file, Bazel will now default to using main
  as the workspace name (instead of "", as previously). The
  repository's runfiles will appear under x.runfiles/main/.
• Bazel does not embed protocol buffer-related rules anymore.
• It is now an error for a cc rule's includes attribute to point to
  the workspace root.
• Bazel warns if a cc rule's includes attribute points out of
  third_party.
• Removed cc_* attributes: abi / abi_deps. Use select() instead.

New features:

• select({"//some:condition": None }) is now possible (this "unsets"
  the attribute).

Important changes:

• java_import now allows its 'jars' attribute to be empty.
• adds crunch_png attribute to android_binary
• Replace --java_langtools, --javabuilder_top, --singlejar_top,
  --genclass_top, and --ijar_top with
  java_toolchain.{javac,javabuilder,singlejar,genclass,ijar}
• External repository correctness fix: adding a new file/directory
  as a child of a new_local_repository is now noticed.
• iOS apps are signed with get-task-allow=1 unless building with -c
  opt.
• Generate debug symbols (-g) is enabled for all dbg builds of
  objc_ rules.
• Bazel's workspace name is now io_bazel. If you are using Bazel's
  source as an external repository, then you may want to update the
  name you're referring to it as or you'll begin seeing warnings
  about name mismatches in your code.
• Fixes integer overflow in J2ObjC sources to be Java-compatible.
• A FlagPolicy specified via the --invocation_policy flag will now
  match the current command if any of its commands matches any of
  the commands the current command inherits from, as opposed to
  just the current command.
• The key for the map to cc_toolchain_suite.toolchains is now a
  string of the form "cpu|compiler" (previously, it was just "cpu").
• Fix interaction between LIPO builds and C++ header modules.
• Ctrl-C will now interrupt a download, instead of waiting for it to
  finish.
• Proxy settings can now be specified in http_proxy and https_proxy
  environment variables (not just HTTP_PROXY and HTTPS_PROXY).
• Skylark targets can now read include directories from
  ObjcProvider.
• Expose parameterized aspects to Skylark.
• Support alwayslink cc_library dependencies in objc binaries.
• Import cc_library dependencies in generated Xcode project.

0.2.2

Release 0.2.2 (2016-04-14)

Baseline: 759bbfe

• 1250fda: Rollback of commit
  3514756.
• ba8700e: Correctly set up build variables for the correct pic
  mode for fake_binary rules.
• 386f242: Automated [] rollback of commit
  525fa71.

New features:

• --extra_entitlements allows passing additional entitlements for
  iOS signing
• The output of -printconfiguration of proguard is available
  through an implicit "[target_name]_proguard.confg" output of
  android_binary (and
  java_binary).
• Objective-C compiler information is now available to Skylark.

Important changes:

• ProGuard relies on bazel to check to see if the inputs have
  changed.
• Build the jsonnet tool for the host when cross-compiling.
• Add ProductType for watch OS 1 extension and application.
• Restrict file types used for "entitlements" attribute to
  [".entitlements", ".plist"]
• Restrict file types allowed for "strings" attribute to ".strings".
• local_repository can take a relative path.
• Support apple_watch1_extension and apple_watch_extension_binary
  rules for creating watch OS 1 extensions.
• implement list.insert for skylark rule
• Enable overriding attributes for Rust binaries.
• ios_device attribute "xcode", for declaring a specific xcode to
  use when selecting iOS simulators.

0.2.1

Release 0.2.1 (2016-03-21)

Baseline: 19b5675

Incompatible changes:

• Skylark rules that are available from their own repository will
  now issue a warning when accessed through @bazel_tools.
• Set --legacy_bazel_java_test to off by default. java_test will
  now have a slightly different behaviour, correctly emitting XML
  file but, as a downside, it needs correct declaration of the
  test suite (see #1017).
• Labels in .bzl files in remote repositories will be resolved
  relative to their repository (instead of the repository the
  Skylark rule is used in).
• Renamed proto_java_library to java_proto_library. The former
  is now deprecated and will print out a warning when used.
• android_sdk now compiles android_jack on the fly from
  android_jar, which means android_jar must be a jar and
  android_jack is now deprecated. The Jack tools (jack, jill,
  resource_extractor) must be specified.
• Any project that depended on the objc_options rule will be
  broken. Can be fixed by adding attrs (infoplists,copts) directly
  to rules depending on the options.
• .aidl files correctly require import statements for types
  defined in the same package and the same android_library.

New features:

• Experimental Windows support is available.
• Experimental support for writing remote repository rules in
  Skylark is available.
• iOS ipa_post_processor attribute allows for user-defined IPA
  edits.
• Adds a to_json method to Skylark structs, providing conversion to
  JSON format.
• Native python rule can depend on skylark rule as long as skylark
  rule provides 'py' provider.
• When using both --verbose_failures and --sandbox_debug, Bazel
  prints instructions how to spawn a debugging shell inside the
  sandbox.
• add flag --sandbox_add_path, which takes a list of additional
  paths as argument and mount these paths to sandbox.

Important changes:

• @androidsdk//:org_apache_http_legacy added for the legacy Apache
  classes for android sdk version 23 and above.
• Genrules correctly work when used with bazel run.
• When namespace-sandbox is run with the -D (debug) flag and
  inside a terminal, it spawns a shell inside the sandbox to aid in
  debugging when the sandboxed command fails.
• Added --artifact to workspace generator for generating workspace
  and build file rules from artifact coodrinates.
• Specifying --experimental_android_resource_shrinking on the
  command line will enable a resource shrinking pass on
  android_binary targets that already use Proguard.
• J2ObjC updated to 1.0.1 release.
• Added "root_symlinks" and "symlinks" parameters to Skylark
  runfiles() method.
• You can no longer use objc_binary targets for the xctest_app
  attribute of an ios_test rule.
• Enable overriding jsonnet binaries and stdlib for Jsonnet rules.
• mount target of /etc/resolv.conf if it is a symlink.
• Tests that failed to build because execution was halted no longer
  print their status.
• Bazel warns if a cc rule's includes attribute contains up-level
  references that escape its package.
• Add repository_ctx.download and repository_ctx.download_and_extract
  function.
