Cherry picks:
+ ef1c6fd33: 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
<dep>.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
