* Preserve original main VM through C API execution
Run and finalize the original main VM while keeping the registered attachment template available without holding its mutex across Python callbacks.
Assisted-by: OpenAI Codex:model version unavailable
* Make unraisable reporting robust at hook boundaries
Keep the existing message API and traceback formatting while handling missing, disabled, audited and failing hooks without panicking.
Assisted-by: OpenAI Codex:model version unavailable
* Separate interactive warning collection from compilation
Retain ordinary warning behavior and typed module APIs while exposing record-local parser warnings and post-warning code generation. Add a source-only lazy future-import guard.
Assisted-by: OpenAI Codex:model version unavailable
* Evaluate native stdin with shared VM record semantics
Use one evaluator for basic REPL and root transports, preserve effective inspect snapshots and future flags, and carry owned host exit status through original-main finalization.
Assisted-by: OpenAI Codex:model version unavailable
* Refresh canonical REPL tests and retire fixed failures
Run update_lib migrate from pinned CPython 3.15.0, preserving three remaining platform/runtime markers and retiring the two traceback/startup failures verified on the native evaluator.
Assisted-by: OpenAI Codex:model version unavailable
* Keep the root compiler dependency for development targets
The native evaluator now compiles through the VM. Only root benchmarks and the parse_folder example use rustpython-compiler directly, so declare it as a dev dependency while preserving VM compiler features.

* Validate explicit conditional failure marker retirement
Require exact selector and original decorator evidence for each conditional expected-failure marker retired by migrate. Preserve undeclared guards and reject missing, duplicate, modified or unconsumed declarations.
Assisted-by: OpenAI Codex:model version unavailable
* Refresh canonical stdin and exception audit tests
Migrate the pinned CPython 3.15.0 modules and their canonical helper fixtures through update_lib. Retire exactly four failure markers proven obsolete by hosted CI, preserving all other existing guards.
Assisted-by: OpenAI Codex:model version unavailable
* Synchronize runpy warning attribution and document remaining capabilities
Migrate whole canonical runpy.py to pass module names to compile. Use update_lib to annotate only reproduced missing-capability cases: absent _testcapi import-event tests, unsupported startup/import-time features, and the deferred frozen-loader module-attribution caller.
Assisted-by: OpenAI Codex:model version unavailable
* Propagate interrupted native stdin reads to signal dispatch
Preserve the shared input buffer and partial bytes while returning EINTR to the VM before retrying. Exercise the transport deterministically and verify a returning SIGINT handler while pipe stdin stays open.
Assisted-by: OpenAI Codex:model version unavailable
* Reject statements after a compound statement in single mode
single_mode_multiple_statements_error now reports "invalid syntax" at the
statement that follows a compound first statement, and interactive_input
runs it right after parsing as compile() does.
The lazy `from __future__` import check moved from lazy_future_import_error
into unsupported_grammar_error, so it applies to every compile mode.

* Remove passing expected failure from test_runpy
test_run_module_filter_syntax_warnings_by_module passes.

* 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.

* 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.

* 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.

* 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.
