Release 3.4.0 (2020-07-13)
Baseline: 7404d17ac76da876ae0b432d1fccf222a9e991fe
Cherry picks:
+ a4334be50a206bf8d676a0196af11056c48ac35b:
fixup! Gracefully handle the lack of subreaper support in Linux.
Incompatible changes:
- This removes the short-lived --process_wrapper_extra_flags
flag, which was introduced primarily to roll out a bug fix.
Unfortunately,
this made us inadvertently expose all of the process-wrapper's
command line
interface to the public, which should not have happened. Given
the corner
case of the utility of this flag, the lack of documentation for
it, and the
fact that it only appeared in a single release, we are treating
this as a
bug instead of a backwards compatibility breakage.
New features:
- bazel info: Allow to specify multiple keys.
- Support code coverage with GCC 9.
Important changes:
- Allow InstrumentedFilesInfo fields to be read from Starlark.
- The --starlark_cpu_profile=<file> 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.
- The --debug_depset_flag has been removed as it is in effect
always on at no cost.
- Rule authors should use the
incompatible_use_toolchain_transition rule attribute to migrate
to using
the toolchain transition. jcater to udpate notes further.
- `apple_binary` rules now accept the `stamp` attribute with the
same
semantics that it has in `cc_binary` rules.
- --incompatible_objc_provider_remove_compile_info turns off
the compile info/mege_zip Starlark APIs in ObjcProvider. See
#11359.
- The --debug_depset_flag has been removed as it is in effect
always on at no cost.
- Fix behavior of ctx.actions.write so content is written without
an incorrect encoding to UTF-8.
See https://github.com/bazelbuild/bazel/issues/10174 for details.
- Collect more performance metrics for worker execution.
- Add flag --incompatible_force_strict_header_check_from_starlark
- Configure coverage and runfiles for sh_library.
- Adds --incompatible_blacklisted_protos_requires_proto_info to
indicate whether proto_lang_toolchain.blacklisted_protos requires
ProtoInfo.
