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.
