 # Standard Pigweed flags
 # ======================
 # All Pigweed projects are expected to set these flags. They mostly pre-adopt
 # future Bazel settings.
 #
 # Do not attempt to configure an autodetected (local) toolchain. We vendor all
 # our toolchains, and CI VMs may not have any local toolchain to detect.

 # Required for new toolchain resolution API.

 # Expose exec toolchains for Python.
 build --@rules_python//python/config_settings:exec_tools_toolchain=enabled

 # Don't propagate flags or defines to the exec config. This will become the
 # default one day (https://github.com/bazelbuild/bazel/issues/22457) and will
 # improve cache hit rates between builds targeting different platforms. This is
 # especially impactful for large host tools like protoc, which will have its
 # cache invalidated when your host C++ config changes.
 common --experimental_exclude_defines_from_exec_config

 # Don't automatically create __init__.py files.
 #
 # This prevents spurious package name collisions at import time, and should be
 # the default (https://github.com/bazelbuild/bazel/issues/7386). It's
 # particularly helpful for Pigweed, because we have many potential package name
 # collisions due to a profusion of stuttering paths like
 # pw_transfer/py/pw_transfer.
