Release 9.0.0-pre.20241119.2 (2024-11-27)

Baseline: ebeab8c

Cherry picks:

   + 650142f:
     Automated rollback of commit
     4515bb6.
   + 4754de2:
     [Rolling release] Do not forward legacy `cmd.exe` variables to
     the server (#24500)
   + 94fb35b:
     Fix rolling release (#24513)

Incompatible changes:

  - Changing --test_env no longer invalidates the analysis cache.
    `ctx.configuration.test_env` may be empty for non-test rules and
    should not be used by such rules.

Important changes:

  - Add a set data type to Starlark, guarded by the
    --experimental_enable_starlark_set flag.
  - symbolic macro attribute inheritance is now marked experimental;
    set --experimental_enable_macro_inherit_attrs flag to enable it.
  - Changing any part of `--run_under` that isn't the label (such as
    the shell command) no longer invalidates the analysis cache.
  - The progress of completed configured aspects is now shown in the
    UI, next to the number of completed targets. Example: "(100
    packages loaded, 10000 targets and 500 aspects configured)".

This release contains contributions from many people at Google, as well as Fabian Meumertzheim, kalvdans, Xùdōng Yáng.

+
+Incompatible changes:
+
+  - On Windows, a change to the output base locking protocol might
+    cause an older Bazel invoked immediately after a newer Bazel (on
+    the same output base) to error out instead of blocking for the
+    lock, even if --block_for_lock is enabled.
+  - The `--watchfs` startup option is now a no-op and will be removed
+    in April 2025. Use the `--watchfs` command option instead.
+  - The mnemonic passed to --worker_extra_flag is now matched against
+    the worker key mnemonic when one is available, instead of the
+    action mnemonic. This makes it consistent with other worker flags
+    taking a mnemonic.
+
+New features:
+
+  - The "blaze --quiet" command line option can now be used to make
+    Blaze emit much less output.
+  - REPO.bazel now allows another directive, "ignore_directories()".
+    It takes a list of directories to ignore just like .bazelignore
+    does, but with glob semantics.
+  - Commands executed by "bazel run" now have two extra environment
+    variables: $BUILD_ID indicates the id of the Bazel command and
+    $BUILD_EXECROOT indicates the execroot of the Bazel server.
+
+Important changes:
+
+  - The stripPrefix parameter of repository_ctx.download_and_extract()
+    and repository_ctx.extract() has been renamed to strip_prefix;
+    the deprecated
+    stripPrefix name remains usable for compatibility.
+  - A no-config transition is now available as `config.no_config()`.
+  - Actions that create runfiles trees are now considered regular
+    actions. This means that they are now reported in statistics,
+    critical paths and the like.
+  - External repositories that are managed by Bzlmod can now contain
+    a top-level `external` directory or package.
+  - `repository_ctx.execute` can now remove an environment variable
+    when executing a process by associating it with the value `None`
+    in the `environment` argument.
+  - Add inherit_attrs param to macro() to allow symbolic macros to
+    inherit attributes from rules or other symbolic macros.
+  - `bazel mod` now tries to evaluate all module extensions, even
+    when some have failed to evaluate.
+  - The new `--inject_repository` flag can be used to add new
+    repositories via the CLI with `--enable_bzlmod`. Such
+    repositories behave as if they were declared by
+    `local_repository` via `use_repo_rule` in the root module.
+  - symbolic macro attribute inheritance is now marked experimental;
+    set --experimental_enable_macro_inherit_attrs flag to enable it.
