# Collect into a .zip file the TEST_MAPPING files for packages whose tests
# should be run in kernel presubmit and postsubmit testing.
# This rule is in this directory
# because these TEST_MAPPING files are used when testing kernel code and
# kernel/tests is the good place for that.
#
# Conventions:
#   - Each package declares a :test_mappings pkg_files() target that contains
#     all TEST_MAPPING files in that package. Avoid
#     exports_files(["TEST_MAPPING"])
#     because it requires this target to poke into the implementation
#     detail of each package, and it is less flexible if the package has
#     more TEST_MAPPING files in the future.
#   - Be careful about package boundaries, especially if you are using a
#     glob() expression. See
#     https://bazel.build/reference/be/functions#glob
#
# Example for a package with a single TEST_MAPPING file at the top level:
#
# pkg_files(
#     name = "test_mappings",
#     srcs = ["TEST_MAPPING"],
#     prefix = package_name(),
#     visibility = ["//kernel/tests/test_mappings:__pkg__"],
# )
#
# Example for a package with multiple TEST_MAPPING files. Use `renames`
#   to preserve the directory structure within the archive:
#
# _TEST_MAPPINGS = glob(["**/TEST_MAPPING"])
# pkg_files(
#     name = "test_mappings",
#     srcs = _TEST_MAPPINGS,
#     prefix = package_name(),
#     renames = {file: file for file in _TEST_MAPPINGS},
#     visibility = ["//kernel/tests/test_mappings:__pkg__"],
# )

# All interesting test_mappings targets, except the one in the kernel tree
# (usually //common).
pkg_filegroup(
    name = "non_kernel_test_mappings",
    srcs = [
        "//external/zlib:test_mappings",
        "//kernel/tests/net/test:test_mappings",
        # Drop prebuilts/rust/TEST_MAPPING because:
        #   - It doesn't contain useful content; the files it imports do not
        #     exist in the kernel tree as of 2024-03-28.
        #   - prebuilts/rust does not exist on android15-6.1 manifest.
        # TODO(b/330775243): Add it back after main-kernel-build-2024 cut over.
        # "//prebuilts/rust:test_mappings",
