Release 3.0.0rc2 (2020-03-10)
Baseline: 3c7cc747ac653dca8b88a9e43726a794e2c27a9c
Cherry picks:
- 4ee52dbdb0351aa2f9c8340e3bacd9a6b36e6a77: Use prefix encoding for paths.
- 9ada0fe73ad3cd0e40c85eb82037ff7ff7f44ef9: Avoid file operations in the sandbox creation critical path.
- 80a2d7cc5f8a22816934dcd2ca9bdf87050f3d9f: Implementation (but not plumbing) of the gRPC remote downloader
- 586eabf419972c74fdd5fef328cfe9a259e035ed: Implement RemoteDownloader w/
--experimental_remote_downloader
Incompatible changes:
- Flip --incompatible_remove_enabled_toolchain_types, so that rules can no longer access enabled toolchain types from the platform fragment.
- The --incompatible_use_jdk11_as_host_javabase flag has been removed (it was flipped in Bazel 0.25.0).
- Using JDK 9 or 10 as a
--host_javabase is no longer officially supported. As always, you can use the @bazel_tools//tools/jdk:toolchain_vanilla Java toolchain to use older or newer JDKs than what Bazel currently supports.
- --fatal_event_bus_exceptions is deprecated and should not be used. Any crashes should be reported so that they can be fixed.
- The old-style binary profile format is no longer suppported, use the new JSON trace profile instead.
Important changes:
- Improve the performance of creating a sandboxed execution root for workers when the number of inputs is large (>1000).
- Treat .cu and .cl files as C++ source. CUDA or OpenCL are not natively supported and will require custom flags to compile with e.g. clang.
- Add actions' primary output details in JSON profile and analysis_v2.proto.
- Add --cds_archive option for embedding CDS archive into deploy JAR.
- Add new global attribute: applicable_licenses
- Package level default with default_applicable_licenses
- guarded by --incompatible_applicable_licenses (default true for Blaze, false for Bazel)
- In support of https://docs.google.com/document/d/1uwBuhAoBNrw8tmFs-NxlssI6VRolid GYdYqagLqHWt8/edit#
- Non-test Java rules no longer require the TestConfiguration and thus --trim_test_configuration is again usable for Java builds
- The flag
--incompatible_always_check_depset_elements is enabled by default.
- --incompatible_objc_compile_info_migration determines whether native rules can assume compile info has been migrated to CcInfo. See https://github.com/bazelbuild/bazel/issues/10854.
- --incompatible_remove_local_resources is true by default. Please use --local_ram_resources and --local_cpu_resources instead of --local_resources.
