* Reject statements after a compound statement in single mode
single_mode_multiple_statements_error now reports "invalid syntax" at the

* Restructure stdin execution after Modules/main.c and pythonrun.c
- src/lib.rs follows pymain_run_python: pymain_run_stdin, pymain_repl,
pymain_run_startup, pymain_run_interactive_hook and pymain_run_pyrepl
return exit codes instead of raising SystemExit.
- VirtualMachine gains run_any_stdin (_PyRun_AnyFile),
run_interactive_loop (_PyRun_InteractiveLoop) and run_simple_stdin;
run_shell feeds rustyline lines into run_interactive_loop, and
sys._baserepl calls run_any_stdin.
- print_uncaught_exception (PyErr_Print) replaces
report_uncaught_exception, and handle_system_exit_and_keyboard_interrupt
replaces handle_reported_exception.
- An unhandled KeyboardInterrupt is recorded and the process exits
through SIGINT after finalization.
- Interpreter::run_main replaces run_with_exit_status and InterpreterExit;
rustpython_capi::run_main_interpreter takes an exit-code callback.
- config_set_inspect audits cpython.PyConfig_Set and rebuilds sys.flags
through set_flag_obj (_PySys_SetFlagObj); the inspect state is an
AtomicBool and dict replace_by_identity is removed.
- add_main_module (PyImport_AddModuleRef("__main__")) is used by the
interactive and simple-file paths.
- The interactive parser warning helpers take their state directly.
Assisted-by: Claude Code:claude-opus-5-5
* Exit through Py_Exit from PyErr_Print and run the basic REPL via stdin
- print_uncaught_exception (PyErr_Print) calls exit_process (Py_Exit) for a
SystemExit when inspect mode is off, instead of returning the exception.
run_interactive_loop no longer checks SystemExit itself and flushes after
printing an error; sys._baserepl returns None.
- exit_process finalizes through VirtualMachine::finalize_ex, which holds
the Py_FinalizeEx steps split out of Interpreter::finalize, and exits
through host_env::os::exit_with_cleanup (C exit()).
- The basic REPL on a terminal (PYTHON_BASIC_REPL, or _pyrepl missing)
runs run_any_stdin instead of the rustyline shell.
- run_shell saves the history after every line.
Assisted-by: Claude Code:claude-opus-5-5
* Display exceptions through PyErr_Display and track the main thread running __main__
- display_exception (PyErr_Display) and display_exception_to (_PyErr_Display)
try traceback._print_exception_bltin before the native printer and flush
the file. PyErr_Print's excepthook fallback, print_exception and
sys.excepthook use them. A missing sys.stderr is reported with
dump_object (PyObject_Dump); a None sys.stderr prints nothing.
- Paths gains program_name (argv[0]) from getpath. The "can't open file"
message uses it with strerror(errno) and goes to sys.stderr.
- running_main holds the ident of the thread running __main__.
pymain_run_python sets it around running the main code, Py_Exit clears it,
the fork child reinitializes it, and _interpreters.is_running reads it
instead of treating the main interpreter as always running.
- Interpreter::run_main clears the unhandled KeyboardInterrupt flag before
running and applies exit_sigint after finalizing; finalize no longer
does.
- run_interactive_loop returns a SystemExit raised outside inspect mode
again and no longer flushes after printing an error; run_shell saves the
history once after the loop.
- pymain_set_inspect reports its error through print_uncaught_exception.
Assisted-by: Claude Code:claude-opus-5-5
* Treat a parse error at the end of the source as incomplete input
A parser error that starts at the end of the source is reported as
_IncompleteInputError when incomplete input is allowed, so the
interactive loop and codeop keep reading after `try:` and its block or
after a decorator line.
Assisted-by: Claude Code:claude-opus-5-5
* Place syntax errors on tokens made up at the end of the input
A parse error on the NEWLINE, DEDENT or ENDMARKER the tokenizer makes up
at the end of the input now carries an EofToken: the number of lines
read and the last line. SyntaxError takes its lineno and text from it,
and its offset is that line's length with end_offset -1, or 0 for both
when the error is raised at the token itself (the generic syntax error
and a missing forced `:` or `(`). Exec input that does not end with a
newline is checked with one appended.

* Slice the source with get when checking an indented block error at EOF
Assisted-by: Claude Code:claude-opus-5-5
* Rename the host exits after C exit() and fix wasi and Windows builds
- host_env::os::exit now calls the C exit() on every platform; on Windows
std::process::exit ends in ExitProcess, so it flushes the Rust stdout
and calls libc::exit there. The former exit, which calls _exit(), is
now exit_immediately, used by os._exit, faulthandler and
posixsubprocess.
- errno::strerror_string is available on wasi.
- PyGlobalState::reinit_running_main is built only where its fork caller
is.

complex.__eq__ and __ne__ converted an int operand to f64 before
comparing, so a complex whose real part is the float nearest to a large
int compared equal to that int even when the values differ:
complex(2**53 + 1) == 2**53 + 1 returned True, while
float(2**53 + 1) == 2**53 + 1 returns False and the two objects hash
differently.
When the imaginary part is zero, compare the real part against the
exact integer with float_ops::eq_int, the helper float's own comparison
uses. This matches CPython, which hands an int operand to float's rich
comparison. test_complex.test_richcompare_boundaries now passes, so drop
its expectedFailure marker.

* Refresh canonical IO tests for weakref finalization
Migrate the complete CPython 3.15.0 test_io package at d220409 with the
fail-closed legacy-map updater, preserving all ten existing guards. Retire
the seven consolidated standalone suites and update io/file dependency
paths with mapping regression tests.
The canonical GC tests ignore ResourceWarning without retaining its
source, so callback-free weakrefs correctly reflect surviving owners.
This closes the stale test dependency exposed by the lifecycle change.
Assisted-by: OpenAI Codex:model version unavailable
* Protect weakref callbacks with the original referent stripe
Follow CPython's free-threading weakref locking model instead of keeping
an independent callback RwLock. Retain the original referent stripe key
so callback access stays synchronized after GC clears the referent.
Unlink and steal callbacks under that stripe, then release ownership
outside the lock. Preserve synchronization for running-world GC paths
and gc.get_referents while keeping ordinary weakref upgrades unchanged.
Assisted-by: OpenAI Codex:model version unavailable
* Defer weakref GC tracking until referent publication
Keep freshly allocated weakrefs out of GC's object lists until they are
linked and their referent is published. Release the referent stripe before
tracking, since tracking can collect and invoke finalizers. Generic reuse
losers remain untracked.
Exercise the allocator boundary directly for reference, proxy, callable
proxy and subclass payloads, and ensure completed constructors track their
objects. This prevents observers from retaining a half-built dead weakref
that later becomes live.
Assisted-by: OpenAI Codex:model version unavailable
* Retain the original weakref stripe lock like CPython
Store a safe handle to the selected static weakref stripe instead of

nonthreaded handle is zero-sized and introduces no locking.

bytearray.__mod__ copied the format and ran the arguments' __repr__,
__str__, __bytes__ and __index__ without holding an export, so a callback
could clear or extend the format and formatting went on with the old
copy:
fmt = bytearray(b"%a end")
class S:
def __repr__(self):
fmt.clear()
return "E"
fmt % S() # bytearray(b'E end'), fmt left empty
CPython holds a buffer on the format for the whole call, so the resize
fails with BufferError and the format is left as it was. Taking an export
for the duration of __mod__ does the same here, the way bytearray.join
already does for its separator.

Accept hexlify keyword arguments and migrate base64 and its tests directly from CPython v3.15.0 using update_lib.
Assisted-by: OpenAI Codex:model version unavailable
* Update Hypothesis fallback for multi-argument examples
Import the CPython 3.15 final fallback helper with scripts/update_lib migrate. Keep canonical base64 round-trip examples unchanged while passing their positional arguments as one subTest message.
Validation: six canonical base64 methods, fourteen fixed examples; bounded source-only runs with the existing same-native PR binary.

* Sync ten foundational Python libraries with CPython 3.15
Migrate _py_abc, stat, genericpath, ntpath, posixpath, functools, gettext, string, optparse, and mimetypes with related canonical tests using scripts/update_lib from CPython d220409a13b77de7a6c30abe16ea90db01528edc. Preserve the existing pure LRU hash-count expected failure.

* Preserve positional-only annotation order for singledispatch
Emit positional-only annotations before regular positional annotations, matching declaration order and the canonical functools regression coverage.

* Preserve explicit customizations during canonical library migration
Add bounded runtime, call, and doctest preservation plus explicit remaining-marker metadata. Support mapped legacy test-package migrations without losing ordered guards, and exclude cache directories from both migration paths while retaining canonical assets.
Validation: 53 bounded host-Python tooling tests passed. Tests inspect source and temporary files without executing migrated fixtures. Existing copy-library cache protection is unchanged. No Lib or interpreter changes.

* Integrate migration preservation into existing updater modules
Keep migration orchestration and guarded package moves in cmd_migrate, and marker/doctest metadata in patch_spec. Reuse AST anchor validation and existing test modules, removing all eleven newly introduced helper, test, and data files.
Require caller-selected doctest metadata instead of embedding syntax-case policy. Reject guarded legacy doctests before package writes. Preserve the prior 53 test scenarios and add seven focused metadata regressions; all 60 bounded host tooling tests passed. No Lib, workflow, or native changes.
