Baseline: 97a8264 Cherry picks: + a0e3bb2: Remove support for authentication and .netrc + ada2c55: Add explicit --sdk argument to xcrun calls + 847df72: toolchain_vanilla: Unset source and target language level versions + 5cfa030: Update java_tools version to javac11-v5.1. Incompatible changes: - Python, Windows: the --[no]incompatible_windows_escape_python_args is no longer supported. (It was flipped to true in Bazel 0.27.0) - --incompatible_use_native_patch is enabled by default - Windows: --incompatible_windows_bashless_run_command is now true by default, meaning "bazel run //foo:bin" will run the binary as a subprocess of the Bazel client. (When the flag is false, the binary is executed as a subprocess of Bash.) - Windows: --incompatible_windows_native_test_wrapper is enabled by default New features: - Genrule now supports `cmd_bash`, `cmd_ps`, `cmd_bat` attributes. More details at https://docs.bazel.build/versions/master/be/general.html#genrule.c md - config_setting can now check multiple values on "--foo=firstVal --foo=secondVal ..."-style flags - tags: use `--experimental_allow_tags_propagation` flag to propagate tags to the action's execution requirements from targets. Such tags should start with: `no-`, `requires-`, `supports-`, `block-`, `disable-`, `cpu:`. See #8830 for details. - Users can now get generated def file from cc_library via "def_file" output group on Windows. - Platform-specific bazelrc: with --enable_platform_specific_config you can enable flags in bazelrc according to your host platform. - tags: use `--experimental_allow_tags_propagation` flag to propagate tags to the action's execution requirements from cc_library or cc_binary targets. Such tags should start with: `no-`, `requires-`, `supports-`, `block-`, `disable-`, `cpu:`. See #8830 for details. - tags: use --experimental_allow_tags_propagation flag to propagate tags to the action's execution requirements from java targets. Such tags should start with: no-, requires-, supports-, block-, disable-, cpu:. See #8830 for details. Important changes: - Bazel Android builds now use aapt2 by default. To revert to aapt, set `--android_aapt=aapt`. - Make either --subcommands or --verbose_failures imply --materialize_param_files - Bazel Android builds now use aapt2 by default. To revert to aapt, set `--an... RELNOTES: None - by default all remote connections considered to be via `gRPC` with TLS enabled, unless other specified. To disable TLS use `grpc://` prefix for you endpoints. All remote connections via `gRPC` affected - `--remote_cache`, `--remote_executor` or `--bes_backend`. http cache/executor is not affected. See #8061 for details. - cc_* rules support non-transitive defines through a 'local_defines' attribute. - Enable incompatible_disallow_rule_execution_platform_constraints_allowed by default (#8136). - incompatible_disallow_split_empty_separator is enabled by default - Fixed Android build issues with aapt2 on Windows. See the [GitHub issue](#9102) for more information. - --incompatible_disable_static_cc_toolchains has been flipped. See #8546. - --remote_default_platform_properties has been deprecated in favor of --remote_default_exec_properties. - The --incompatible_make_thinlto_command_lines_standalone flag has been flipped, see #6791 for more information. - The --incompatible_use_specific_tool_files flag has been flipped. See #9126 for more information. - Clarify default visibility. - Enables incompatible_auto_configure_host_platform - New incompatible flag --incompatible_disable_depset_items disables the "items" parameter in the Starlark depset constructor. Use "direct" and "transitive" parameters instead. - --incompatible_assignment_identifiers_have_local_scope is enabled - incompatible_disable_partition_default_parameter is enabled by default () - incompatible_restrict_attribute_names is enabled (#6437) - The --incompatible_disable_nocopts flag has been flipped. See #8546 for more information. - Deprecated Java-Starlark API java_common.create_provider is removed. JavaInfo() legacy args (actions, sources, source_jars, use_ijar, java_toolchain, host_javabase) are removed. - The flag incompatible_disallow_hashing_frozen_mutables is enabled (#7800) - `maven_jar` and `maven_server` now disallow using plain HTTP URLs without a specified checksum. If you are still using `maven_jar`, consider migrating to [`rules_jvm_external`](https://github.com/bazelbuild/rules_jvm_ext ernal) for transitive dependency management. See [#8607](#8607) for more information. - Added `sha256` and `sha256_src` attributes to `maven_jar`. Please consider migrating to SHA-256 as SHA-1 has been deemed cryptographically insecure ([https://shattered.io]()). Or, use [`rules_jvm_external`](https://github.com/bazelbuild/rules_jvm_ext ernal) to manage your transitive Maven dependencies with artifact pinning and SHA-256 verification support. - introducing per-target exec_properties - Bazel now supports ThinLTO builds on Linux for Clang versions >= 6.0. ThinLTO can be enabled through --features=thin_lto - The Target.output_group field in Starlark is removed. Use OutputGroupInfo instead. See #7949 for details. - Make a number of parameters of Starlark builtin functions positional-only (as opposed to specifiable by keyword). See #8147 for details. - incompatible_skip_genfiles_symlink is enabled by default (#8651) - Change Pruned events will fire immediately after being checked. - --incompatible_remove_legacy_whole_archive has been flipped.
