Release 8.0.0-pre.20240925.4 (2024-10-03)

Baseline: f4d92d45be3617b72c21ad5ce8912fa548472e50

Cherry picks:

   + 99434b16ba41677b92f7eb79d5d8dcb1130d7c47:
     Automated rollback of commit
     4607ad439fe8869c8e8951d953e2d3adb613e6d6.

Incompatible changes:

  - `ctx.resolve_tools` is no longer available by default, in
    preparation for complete removal. See
    https://github.com/bazelbuild/bazel/issues/22249 for migration
    instructions. Use `--noincompatible_disallow_ctx_resolve_tools`
    to temporarily make it available again.
  - The `aquery` command now reports all potential inputs of actions
    that support input discovery, including the input headers of C++
    compilation actions and those explicitly marked as unused through
    the `unused_inputs_list` argument to `ctx.actions.run`. Set
    `--noinclude_pruned_inputs` to omit pruned inputs from `aquery`
    output when running it after action execution.
    RELNOTES[INC]: This is not a release note, but a reminder to
    remove the note for `--include_scheduling_dependencies`, which
    was introduced in the 8.x tree but won't make it into the final
    release.
  - `--zip_undeclared_test_outputs` now defaults to false, causing
    undeclared test outputs (i.e., files written to
    `$TEST_UNDECLARED_OUTPUTS_DIR` by a test) to be produced as a
    directory instead of a zip file.
  - --legacy_important_outputs is flipped to false. See #14353 for
    details

New features:

  - Bazel can now parse .scl files, a dialect of Starlark without
    Bazel-specific symbols.
  - Dormant dependencies and materializer functions are now available
    with the --experimental_dormant_deps flag.

Important changes:

  - Deleted native Android mobile-install
  - Repository rules instantiated in the same module extensions can
    now refer to each other by their extension-specified names in
    label attributes.
  - A new experimental flag,
    `--experimental_build_event_output_group_mode`, allows users to
    change how a given output group's files are reported in BEP. The
    current behavior is `FILESET` which populates
    `OutputGroup.file_sets`. Users may now specify `INLINE` to
    instead report files directly in the
    `TargetComplete`/`AspectComplete` event under
    `OutputGroup.inline_files`. Users may also specify `BOTH` to
    populate `OutputGroup.file_sets` and `OutputGroup.inline_files`.
  - Bazel no longer has the android_binary, android_library,
    android_device_script_fixture and android_host_service_fixture
    rules. Use https://github.com/bazelbuild/rules_android instead.
    See https://github.com/bazelbuild/bazel/issues/23199
  - Bazel no longer has the android_sdk_repository rule. Use
    https://github.com/bazelbuild/rules_android instead.
  - Uploading local action results to a disk or remote cache now
    occurs in the background whenever possible, potentially
    unblocking the execution of followup actions. Set
    `--noremote_cache_async` to revert to the previous behavior.
  - `--incompatible_remote_downloader_send_all_headers` is removed.
  - `--build_event_upload_max_threads` is removed.
  - `incompatible_remote_output_paths_relative_to_input_root` is
    removed.
  - The default value of
    `--experimental_remote_cache_compression_threshold` is changed to
    `100`.
  - Build without the Bytes is disabled when using HTTP cache.
  - Build without the Bytes is disabled when using HTTP cache.
  - Symlink trees are now created through direct filesystem calls by
    default, instead of delegated to a helper process. On Windows,
    this entails respecting the `--windows_enable_symlinks` flag,
    falling back to a copy when the flag is unset (the helper process
    always attempts to create symlinks, irrespective of the flag).
    Set `--noexperimental_inprocess_symlink_creation` to temporarily
    revert to the previous behavior, which will be removed in a
    future release.
  - By default, coverage artifacts will be reported inline in the
    `TargetComplete` event. To disable this behavior, pass
    `--experimental_build_event_output_group_mode=baseline.lcov=named_
    set_of_files_only`.
  - Uploading local action results to a disk or remote cache now
    occurs in the background whenever possible, potentially
    unblocking the execution of followup actions. Set
    `--noremote_cache_async` to revert to the previous behavior.
  - Overrides in the root MODULE.bazel file are now ignored with
    `--ignore_dev_dependency`. (Overrides in non-root modules are
    already ignored.)
  - Added support for using a remote cache that evicts blobs and
    doesn't have AC integrity check (e.g. HTTP cache).
  - Undeclared test outputs are now reported individually in the BEP,
    unless zipping is enabled via `--zip_undeclared_test_outputs`.
  - The native version of android_tools_defaults_jar is no longer in
    Bazel. Use https://github.com/bazelbuild/rules_android instead.
  - Bazel fetch and vendor command now supports --target_pattern_file
    for specifying target patterns.
  - The compact execution log now stores runfiles in a more compact
    representation that should reduce the memory overhead and log
    output size, in particular for test spawns. This change required
    breaking changes to the (experimental) log format.
  - `override_repo` and `inject_repo` can be used to override and
    inject repos in module extensions.
  - Patches to the module file in `single_version_override` are now
    effective as long as the patch file lies in the root module.
  - If `--allowed_cpu_values` is set, the `--cpu` flag value is
    validated against it.
