Release 2.2.0rc1 (2020-02-14)
Baseline: 78055efad0917b848078bf8d97b3adfddf91128d
Incompatible changes:
- The --[no]incompatible_windows_bashless_run_command flag is no longer supported. It was flipped in Bazel 1.0
- The --[no]incompatible_windows_native_test_wrapper flag is no longer supported. It was flipped in Bazel 1.0
Important changes:
- Consistent target naming style in example target names.
- cquery's config() now supports arbitrary configurations.
- The flag --incompatible_disallow_dict_lookup_unhashable_keys is removed.
- Include target label in Python version error message.
- The flag --incompatible_remap_main_repo is removed.
- Windows: we now discourage running Bazel from MSYS2 because of a newly found bug (#10573)
- Reduced the packaging time (
package-bazel.sh) for the //src:bazel-dev Bazel development build target from 14s to 6s. Use //src:bazel-dev if you're iterating rapidly on a local Bazel changes, and use //src:bazel --compilation_mode=opt for release builds.
- cquery: "//foo:bar" now means "all configured targets with label //foo:bar" instead of "choose an arbitrary configured target with label //foo:bar". See cquery docs for details.
- WORKSPACE and BUILD.bazel files of http_archive repositories can now be patched using the "patch_cmds" and "patches" attributes.
- Actions with "parse" on the critical path should no longer finish in the future.
- Flags that affect external repositories like "--override_repository" can now be addressed in bazelrc files using the "common" command, without causing commands like "bazel shutdown" to fail.
- The flag --incompatible_disallow_unverified_http_downloads is removed.
- Create the incompatibleApplicableLicenses flag. We plan to flip this from false to true in Bazel 4.x. Implementation to follow.
- 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.
- 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.
- The --starlark_cpu_profile= flag writes a profile in pprof format containing a statistical summary of CPU usage by all Starlark execution during the bazel command. Use it to identify slow Starlark functions in loading and analysis.
- --ram_utilization_factor will be deprecated. Please use --local_ram_resources=HOST_RAM*
- Docs: glob() documentation is rewritten, and now it points out a pitfall of rules shadowing glob-matched files.
