* Sync Python 3.15 core library tests and repr type errors
Synchronize ten selected library paths from CPython 3.15.0 at
d220409a13b77de7a6c30abe16ea90db01528edc using the canonical updater,
retaining existing RustPython adapters and failure markers.
Match generic __repr__ invalid-result errors to the qualified type-name
format required by the canonical ExceptionGroup regression, preserving
string results and exceptions raised by the implementation.
Implementation, source review, and validation were AI-assisted. The model
version identifier is unavailable; automated checks are not human

* Stage profiling root as a namespace until sampling is available
Omit the whole newly added canonical package initializer rather than
advertise an absent sampling module or hand-edit canonical __all__.

* Support collision-safe frozen package containers
Generate empty frozen packages only for source namespace directories with
real frozen descendants. Preserve genuine modules and packages across
frozen-library registrations while retaining real-real replacement order.
Record the container marker in FrozenModule and its library envelope;
legacy module/package encodings remain unchanged. This is closed-tree
frozen packaging, not full PEP 420 namespace merging.
Add structural codec, mock generator, and registration-priority checks.
* Revert frozen package containers before restoring canonical profiling root
The container implementation changed filesystem namespace precedence.
Restore the existing importer and frozen envelope unchanged; the following
offline sampling closure restores the canonical regular package root.
This reverses d5a8049234.
Assisted-by: dot:GPT-6.1
* Restore canonical profiling package with offline sampling codec
Provide native records, status constants and genuine uncompressed binary
reader/writer APIs for canonical offline tools. Keep the unsupported live
process capability absent and preserve existing canonical test gates.
Restore the complete selected sampling production/test/assets closure via
update_lib, including its asyncio frame-schema dependency. The prior frozen
container extension is reverted separately; canonical packages work with
both filesystem and frozen imports without changing namespace semantics.

* 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

Copy the missing test_monitoring dependency from pinned CPython 3.15.0 through scripts/update_lib, retaining existing suite guards.
Assisted-by: OpenAI Codex:model version unavailable
* Match observed monitoring source layers and tool release ordering
Model active source instrumentation across all subscribed tools instead of unconditional legacy edge pairing. Preserve tool names during unlocked callback finalization before releasing them.
Assisted-by: OpenAI Codex:model version unavailable
* Preserve code qualnames and monitoring event-site identity
Retain decoded WTF8 qualnames, use exact-str marshal dispatch, and model wrapped branch dispatch with physical DISABLE sites. Retire the proven monitoring shutdown guard through update_lib.

* Align weak-reference collection with Python 3.15 finalization
Trace and retain owned callback edges independently of weak referent links.
Clear callback-bearing weakrefs before finalizers, suppress callbacks from
unreachable weakrefs, and close remaining weakref ingress after resurrection
checks while the world is stopped. Publish and unlink intrusive nodes safely.
Refresh weakref and canonical weakref/GC/finalization tests through update_lib
from pinned CPython 3.15.0. Retire four obsolete guards only after fresh body
passes, retaining applicable RustPython limitations.

* 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.

* 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
retaining and rehashing the referent address. Keep the same lock after
referent clearing, matching CPython free-threaded weakrefs_lock. The
nonthreaded handle is zero-sized and introduces no locking.
Preserve lock selection, acquire/release ordering, fork reset, deferred
GC publication, and callback-owner release outside the stripe. No new
locks or unsafe code are needed.

Import canonical descriptor tests through update_lib, preserving existing guards. Support tuple member slots, distinguish base reassignment from class layout compatibility, and share object-owned generic descriptors.
Assisted-by: OpenAI Codex:model version unavailable
* Refresh canonical importlib and preserve native import callback
Cache the original builtin __import__ callback so CPython 3.15 importlib's
hierarchical locking uses the existing native parent-initialization path.
Refresh the complete canonical importlib and related test/helper families
from CPython d220409a13b77de7a6c30abe16ea90db01528edc through update_lib.
Preserve both nondecorator importlib guards in the updater. Add explicit
hash-pinned removal of reviewed obsolete canonical files, with full
preflight, dry-run, idempotence and refusal tests. Preserve empty fixtures.
Assisted-by: OpenAI Codex:model version unavailable
* Complete canonical inspect and types closure for importlib metadata
Refresh whole canonical inspect/types production and related test families
through update_lib after hosted CI exposed stale __cached__ consumers.
Add coroutine and async-generator state getters, with closed-state priority
for reentrant frame-local finalizers, and expose the existing frame-locals
proxy type with its CPython class documentation.
Preserve the optional _datetime and unittest import blocks through a narrow
migration adapter. Retain canonical assertions and existing guards; record
the missing LazyImportType expectation before adding a conditional expected
failure, and capability-skip only the two absent-_testcapi CLI fixtures.
Assisted-by: OpenAI Codex:model version unavailable
* Reject canonical removal junctions and read UTF-8 manifests
Reject junctions alongside symlinks in the existing path-component preflight and revalidation. Decode removal manifests explicitly as UTF-8. Add regressions for whole-batch refusal, revalidation, and Unicode dry-run/apply/idempotence.

Warn on the deprecated shared string keyword and refresh the complete
hashing libraries, canonical suites, and shared helper from CPython
v3.15.0 (d220409a13b77de7a6c30abe16ea90db01528edc) with update_lib.
Keep the six-file family independent and add no RustPython test guards.

Refresh ssl.py and test_ssl.py through update_lib from CPython d220409a13b77de7a6c30abe16ea90db01528edc without local test changes. Implement rustls cipher-suite, group and signature policy, negotiated-group reporting, EOF and session-policy behavior.
Keep OpenSSL and wasm API imports compatible, with genuine version-gated queries and honest unsupported capabilities. Repair OpenSSL callback ownership and traversal, callback exceptions, EOF and shutdown, PHA, session destruction, and system-error decoding exposed by canonical coverage. Preserve existing I/O locking; the inherited optional-backend full-duplex hang remains a separate driver prerequisite.

* Align runtime metadata and annotation cache contracts with Python 3.15
Preserve function name identity, implicit wrapper metadata and slice generic aliases. Match annotation dictionary and reentrant publication contracts, releasing displaced Python owners outside locks in the required phases. Refresh the matching canonical annotation tests through update_lib.
Assisted-by: OpenAI Codex: gpt-6.1-sol
* Refresh canonical generic alias coverage for slice
Migrate the complete Python 3.15 test_genericalias file through update_lib. Preserve the full canonical type list and capability guards so normal test runs cover slice subscripting.

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.
This lets test_mod_concurrent_mutation in test_bytes run again.
