### Common Configuration ###
# Workaround https://github.com/bazelbuild/bazel/issues/23743
common --experimental_merged_skyframe_analysis_execution=false
# Disable Aspect Build telemetry collection
common --repo_env=ASPECT_TOOLS_TELEMETRY=-all
# Set rules_python repo debug verbosity to ERROR
common --repo_env=RULES_PYTHON_REPO_DEBUG_VERBOSITY=ERROR
## rules_python venv bootstrap (rules_python 2.x direction; system_python is the legacy mode being phased out).
# Use the script-based stage-1 launcher (a `#!/usr/bin/env bash` wrapper that invokes the interpreter inside the
# binary's own venv) instead of the legacy `system_python` launcher (a `#!/usr/bin/env python3` script).
common --@rules_python//python/config_settings:bootstrap_impl=script
# Materialize the venv's bin/python3 as a regular placeholder file (recreated at runtime) rather than a build-time
# declared symlink to the hermetic interpreter This is the upstream-supported mode for packaging py_binary venvs into
# tar/OCI images.
common --@rules_python//python/config_settings:venvs_use_declare_symlink=no

## Forward-compat flags (will become defaults in future Bazel versions; opt in early to ease migration).
# Require explicit __init__.py for python packages
common --incompatible_default_to_explicit_init_py=true
# Isolate actions from host env for better hermeticity
common --incompatible_strict_action_env=true


### Build Configuration ###
# Prune unused srcs from tar action cache keys
build --@aspect_bazel_lib//lib:tar_compute_unused_inputs
# Prevent __pycache__ pollution in workspace
build --action_env=PYTHONDONTWRITEBYTECODE=1
# Persist the multi-GiB OCI pip dependency layer tarballs in bazel-out instead of re-fetching them from the
# (disk/remote) cache on every build, which Build-without-the-Bytes would otherwise do for these intermediate outputs.
build --remote_download_regex=.*(app_pip_.*_layer|gpu_core_layer)\.tar$
# Prevent __pycache__ pollution in test sandbox
build --test_env=PYTHONDONTWRITEBYTECODE=1

# Workspace status stamping (STABLE_GIT_SHA in stable-status.txt). Without this, `bazel build` would silently drop
# git-SHA stamping.
build --workspace_status_command=tools/workspace_status.sh
