literal: reject internal whitespace in complex::parse_str (#8242)
parse_str split the token then parsed each part with float::parse_str, which tolerates surrounding whitespace, so "1 +2j" parsed as (1+2j). Reject whitespace inside the token after stripping optional parentheses. Add unit tests and complex() snippet tests. Assisted-by: Claude |

Support xml.sax pyexpat setup APIs (#8238)
* Let xml.sax initialize pyexpat-backed parsers RustPython already exposes an Expat-like XML parser, but xml.sax expects a few setup APIs before parsing. Add compatible parser setup methods and constants without pretending to implement full Expat external entity behavior. Constraint: Lib/test changes only remove expectedFailure markers for tests that now pass; test bodies and assertions are unchanged. Rejected: Implementing full Expat parameter entity parsing | xml-rs does not expose that configuration and the immediate failure is the missing setup API.

Titlecase the first-of-word code point without leading adjustment (#8241)
case::{title,capitalize}_wtf8 pass a single first-of-word code point to
TitlecaseMapper::titlecase_segment. Under the default Auto leading
adjustment the mapper looks for a Letter/Number/Symbol/Private_Use head
and skips anything else, dropping the titlecase mapping of cased marks
such as U+0345 (COMBINING GREEK YPOGEGRAMMENI) -> U+0399: 'ͅ'.title()
returned 'ͅ' instead of 'Ι'. Use LeadingAdjustment::None so the
given code point is titlecased directly, matching CPython str.title and
str.capitalize.

Complete rustpython-unicode isolation: case mapping, casing predicates, sre parity (#8237)
* Move str casing into rustpython-unicode::case and drop icu from vm
Add code-point simple mappings (simple_lowercase/uppercase/titlecase/fold),
casing predicates (is_lowercase/is_uppercase/is_titlecase/is_cased/
is_case_ignorable), and the string-level capitalize/title/swapcase/casefold
helpers to crates/unicode/src/case.rs, moving the titlecase segmentation and
final-sigma logic out of vm/builtins/str.rs verbatim. str.rs and anystr.rs now
call through the crate; the is_cased kernel takes plain fn(char)->bool
predicates instead of icu BinaryProperty generics.
Remove icu_casemap/icu_locale/icu_properties/writeable from crates/vm and the
now-unused VecFmtWriter helper. crates/unicode is the only workspace member
with a direct icu dependency. str.lower/upper keep using Wtf8::to_lowercase/
to_uppercase.
Assisted-by: Claude
* Route sre is_uni_space through unicode::classify::is_space
SRE_UNI_IS_SPACE is Py_UNICODE_ISSPACE. Replace the hand-rolled BMP code-point
list with classify::is_space, which is differential-tested against CPython. A
full-range sweep confirms the two agree on every code point.
Assisted-by: Claude
* Use simple case mappings and the Cased property for sre IGNORECASE
lower_unicode/upper_unicode took the first char of the full case mapping, so
code points with a full mapping but no simple one were miscased (e.g.
upper_unicode('ß') returned 'S'). Route them through case::simple_lowercase/
simple_uppercase, matching Py_UNICODE_TOLOWER/TOUPPER.
_sre.unicode_iscased derived casedness from those mappings, which only held
while the full mapping was used; with simple mappings a cased code point that
maps to itself (e.g. the ſt/st ligatures, U+FB05/06) read as uncased and lost its
_casefix equivalence. Query the Cased property directly via case::is_cased.
Assisted-by: Claude
* Sweep casing predicates and simple lowercase mapping against CPython
Extend the differential harness to cover is_lowercase/is_uppercase/is_titlecase/
is_cased over the full scalar range, sourced from str.islower/isupper, the Lt
category, and _sre.unicode_iscased. Add a parallel sweep of the simple lowercase
mapping (Py_UNICODE_TOLOWER via _sre.unicode_tolower) with its own version-skew
allow-list; CPython exposes no simple-uppercase oracle, so toupper stays on the
SRE unit tests.
Record the U+0295 Ll->Lo recategorization (Unicode 16.0.0 -> 17.0.0) as a known
reverse-direction divergence so the skew regenerator still rejects genuine
regressions.

Thread-safe type operations: type lock, QSBR type-cache reclamation, GC stop-the-world, and interpreter optimizations (#7416)
* type lock * Drop old PyObjectRef outside type lock to prevent deadlock Dropping values inside with_type_lock can trigger weakref callbacks, which may access attributes (LOAD_ATTR specialization) and re-acquire the non-reentrant type mutex, causing deadlock. Return old values from lock closures so they drop after lock release. * Align type lock behavior with CPython * Add PUBLISHED flag bit to RefCount state word Assisted-by: Claude * Add QSBR module for deferred memory reclamation Assisted-by: Claude * Defer memory free of cache-published objects via QSBR Assisted-by: Claude * Wire QSBR checkpoints into thread lifecycle and eval breaker Assisted-by: Claude * Publish type-cache values to QSBR and bypass cache without a VM Mark cached type-method values as QSBR-published before storing their pointer in TYPE_CACHE, so racing readers never try-incref freed memory. Debug-assert that the current thread is ATTACHED whenever a lock-free cache read happens. Delete find_name_in_mro_without_vm and its unsound direct SeqLock read outside any VM/thread registration; find_name_in_mro now falls back to the locked, uncached MRO walk when no VM is current. This also removes assign_version_tag()'s last caller, so its unlocked fallback is deleted along with it (version_for_specialization keeps the locked path). VirtualMachine::initialize() runs Python bytecode (e.g. importing codecs/encodings) before any enter_vm scope exists, which left the bootstrap thread not ATTACHED for cache reads during startup. Add thread::VmBootstrapGuard, an RAII counterpart to enter_vm usable across statements that need &mut VirtualMachine, and wrap initialize() with it. Assisted-by: Claude * Use try-incref reads and QSBR-backed swaps in specialization cache Assisted-by: Claude * Reset QSBR thread registry after fork in the child Add Qsbr::reset_after_fork, which clears the registered thread slots before draining the retire queue. Call it in py_os_after_fork_child, right after type_cache_after_fork() and before _thread::after_fork_child() re-registers the surviving thread. Dead parent threads' Arc<QsbrSlot> handles live on in the child's copied memory with no destructor ever running, so without this the registry keeps them 'online' forever and future grace periods never complete. Assisted-by: Claude * Add threaded stress test for type cache mutation races Assisted-by: Claude * Restrict qsbr internals to pub(crate) and fix clippy lints Downgrade pub items in the private qsbr::threading module (QsbrSlot, Qsbr, QSBR, and its methods) to pub(crate), since they were never reachable outside the crate. Downgrade ThreadSlot::qsbr accordingly to avoid a private-interfaces warning. Import Arc/Weak from alloc instead of std to match clippy::std_instead_of_alloc. Rewrite the process() comment: goals are not strictly ordered by push order since advance() and the queue push aren't atomic together, so concurrent free_delayed calls can interleave; the drained prefix stays sound because each item individually passed poll, with reordering only affecting reclamation latency. Assisted-by: Claude * Gate per-instruction QSBR check behind a global pending flag eval_breaker_tripped() and check_signals() called thread::qsbr_break_requested() on every bytecode instruction, which does a thread-local lookup, RefCell borrow, and atomic load even when no QSBR retirement is pending. This caused a measured 10-18% slowdown on tight interpreter loops. Add Qsbr::pending, a global AtomicBool set under the queue lock while free_delayed() holds a retired allocation, and cleared under the same lock by process()/drain_all() once the queue empties. The hot path now checks Qsbr::break_pending() (a single relaxed static load) before touching thread-local state, and only pays the TLS cost while a retirement is actually in flight. Assisted-by: Claude * Merge signal and QSBR eval-breaker flags into one atomic word Replace the separate ANY_TRIGGERED AtomicBool and QSBR pending AtomicBool checks in the per-instruction eval-breaker path with a single AtomicU8 (EVAL_BREAKER) holding a bit per source. The global QSBR instance mirrors its pending state into the QSBR bit under the same queue-lock critical sections that already toggle pending, while local QSBR instances used by unit tests are left untouched. eval_breaker_tripped() and check_signals() now read/act on the merged word (eval_breaker_pending(), qsbr_bit_set()) instead of issuing two separate atomic loads per instruction. set_triggered() switches from store to fetch_or so a signal handler never clobbers the QSBR bit. Removed the now-unreferenced is_triggered() helper; break_pending() is kept for unit tests only and marked allow(dead_code) outside test builds. Assisted-by: Claude * Skip freelist reuse for published objects in default_dealloc Freelist-eligible payloads (tuple, int, list, dict, float, ...) were routed to T::freelist_push before ever reaching PyInner::dealloc, so a published object (e.g. a tuple cached as a type attribute) bypassed the is_published -> free_delayed QSBR hook entirely. That let PyRef::new_ref reuse the slot and rewrite the refcount word with a non-atomic core::ptr::write racing a reader's atomic try-incref, and let FreeList::drop call alloc::dealloc directly while a reader could still be mid-read. Gate the freelist branch in default_dealloc on RefCount::is_published(), checked before any teardown. A published object now always falls through to PyInner::dealloc, whose existing hook defers the memory free via QSBR. Document the non-unix (e.g. Windows) reclamation-latency limitation in the QSBR design doc's Lifecycle integration section (previously only noted in a code comment in vm/thread.rs). Extend the type-cache stress test so the mutator also churns a freelist-eligible published tuple class attribute (C.shape), read by readers each inner loop and deleted on the same cadence as C.m, to exercise the fixed bypass. Assisted-by: Claude * Use itoa for PyInt::to_str_radix_10 i64 fast path Format small integers with itoa::Buffer instead of i64::to_string() in PyInt::to_str_radix_10(), which backs both str(int)/repr(int) for exact int and PyObject::str()'s exact-int fast path. Adds the itoa crate as a workspace dependency. Assisted-by: Claude * Make object attribute dunders wrapper descriptors Remove the __getattribute__, __setattr__ and __delattr__ #[pymethod]s from PyBaseObject so add_operators installs PyWrapper slot wrappers for them from the #[pyslot] functions instead of method descriptors. lookup_slot_in_mro now classifies these entries as NativeSlot, so heap types without Python-level overrides keep the native getattro/setattro slot functions, which lets LOAD_ATTR/STORE_ATTR specialization apply to instances of Python-defined classes. Since __setattr__ and __delattr__ share the setattro slot, resolve both names together in update_one_slot: overriding only one of them no longer lets the other name's native resolution overwrite the dispatching wrapper. Assisted-by: Claude * Resolve TpSetattro pair on attribute deletion, not just addition update_one_slot's TpSetattro branch only ran the combined __setattr__/__delattr__ resolution (added in the previous commit) when ADD was true. On deletion (e.g. del C.__setattr__), it fell back to inherit_from_mro, which copies the base class's slot and discards the class's own remaining Python-level override of the other name. lookup_slot_in_mro reads the current attribute dicts, so the same resolution is correct for both addition and deletion; the ADD-only guard is removed and the logic now always runs. Assisted-by: Claude * Generate Opcode::cache_entries/deopt as table lookups generate_rs_opcode_metadata.py now emits a 256-entry const array for each function instead of a chained match over opcode names. Opcode::deopt() indexes an [Option<Opcode>; 256] table built from the existing specialization-to-base mapping, and Opcode::cache_entries() indexes a [u8; 256] table that bakes in the same deopt/to_base composition deoptimize() previously performed before its own match. Regenerated opcode_metadata.rs from the updated script; PseudoOpcode's bodies are unchanged since it has no cache/deopt entries to table. Added an exhaustive test in instruction.rs that checks every valid u8 opcode against a frozen copy of the old chained-match bodies. Assisted-by: Claude * Make Opcode/Instruction numeric conversions O(1) Opcode::as_numeric, Opcode::as_instruction and Instruction::as_opcode were each a per-variant match over ~230 arms in the define_opcodes! macro. Opcode now carries the same explicit $op_id discriminants and #[repr($typ)] as Instruction, which makes the conversions sound as: - Opcode::as_numeric: a plain `self as $typ` identity cast. - Opcode::as_instruction / Instruction::as_opcode: a mem::transmute, relying on both enums sharing one-$typ-wide layout (Instruction's payload fields are all the zero-sized Arg<T> marker, checked by a new per-instantiation size_of assertion). try_from_numeric is left as a match: $op_id values have gaps (specialized/instrumented opcode ranges), so a range check can't replace it. Adds #[inline] to the rewritten conversions plus deoptimize, and to the small generated wrapper/table-lookup functions from the previous opcode-metadata change (as_u8/as_u16, cache_entries, deopt, to_base) via generate_rs_opcode_metadata.py, then regenerates opcode_metadata.rs. Extends the instruction.rs equivalence-test pattern with two exhaustive tests (u8 and u16 instantiations) checking the new identity-cast/transmute conversions against the untouched try_from_numeric/TryFrom paths. Assisted-by: Claude * Pop CallIsinstance arguments directly instead of collecting into Vecs The specialized handler built two heap-allocated Vecs per call (pop_multiple().collect() plus a with_capacity(2) buffer) before invoking is_instance. Pop the class and instance straight off the stack for the effective two-argument case, removing the per-call allocations. Assisted-by: Claude * Inherit tp_new instead of always installing new_wrapper update_one_slot's TpNew branch stored new_wrapper for every ADD, so all heap types had slots.new == new_wrapper and the CallAllocAndEnterInit specialization never fired. Now __new__ is resolved through the MRO dicts: an own or Python-level definition installs new_wrapper, while a builtin __new__ entry (or none) inherits slots.new from the solid base. The now-reachable CallAllocAndEnterInit path gains the missing guards: the specializer requires co_argcount == oparg + 1 (via can_specialize_call) and rejects generator-like __init__, and the handler re-checks the argcount against the class-level init cache. Without the argcount check, __init__ defaults broke re._parser (UnboundLocalError in SubPattern.__init__). Remove the now-unused is_simple_for_call_specialization. Assisted-by: Claude * Skip locals dict allocation for the init-cleanup shim frame Mark the shim code object NEWLOCALS and create the shim frame with no locals mapping so FrameLocals::lazy() is used. The shim only executes ExitInitCheck/ReturnValue and never touches locals, so this removes one dict allocation per specialized instantiation. Assisted-by: Claude * Guard CALL_ALLOC_AND_ENTER_INIT with cached function version The init specialization cache stored only the type version, so swapping __init__.__code__ (which zeroes func_version) did not deopt the warmed call site and stale code assumptions (argcount shape, no varargs/kwonly, not a generator) were applied to the new code object. Store get_version_for_current_state() in the specialization cache when caching __init__ and re-check func_version() in the handler before using the cached function, deopting to the generic call path on mismatch, the same way the getitem specialization cache does. Assisted-by: Claude * Apply rustfmt and ruff-format fixes to files from earlier commits Assisted-by: Claude * Add frame object freelist Frame.iframe becomes FrameUnsafeCell<Option<InterpreterFrame>> so a dead frame can be left as an empty husk. Traverse::clear extracts all owned child references (including localsplus values via LocalsPlus::clear_into) and empties the cell. Dead frame allocations are cached in a thread-local FreeList<Frame> (up to 200 entries) and reused by PyRef::new_ref. clear_generator returns early when the frame was already cleared by cycle collection; generator drops can run after tp_clear of their frame. gc: skip tp_clear for objects saved to gc.garbage by DEBUG_SAVEALL, since they remain reachable from Python. Assisted-by: Claude * Drop frame children directly in tp_clear instead of extracting Pushing the frame's ~10 child references into the clear buffer grew a Vec on every frame deallocation. Take the interpreter frame out of the cell and drop it in place; LocalsPlus::clear_into is removed. Assisted-by: Claude * Untrack objects before tp_clear and guard cross-thread f_locals The cycle collector called tp_clear on unreachable objects while they were still linked into the GC generation lists, so another thread could obtain a strong reference to an already-cleared object (e.g. a frame husk with iframe == None) via gc.get_objects() and access the cleared payload. Untrack the dead set before the clear phase, mirroring the untrack-then-clear ordering of the refcount dealloc path. Objects that gained an external reference before untracking are found by comparing each object's strong count against the references coming from within the dead set; such late-resurrected objects and everything reachable from them are re-tracked and skipped, letting a later collection retry once the external references are released. Also reject f_locals access for a frame currently executing on another thread. Reading fastlocals of such a frame races with the executing thread overwriting the slots (torn reads of dropped values). Access from the executing thread itself (locals(), trace callbacks) is still allowed via the current-frame chain check. Assisted-by: Claude * Skip localsplus heap copy for uniquely referenced dying frames release_datastack_frame now checks the frame's strong count after untracking it from the GC generation lists. When the caller holds the only reference, localsplus values are dropped in place and the data stack storage is released without the heap copy; escaped frames (traceback, sys._getframe, trace callbacks) keep the copy path. The three inline materialize+pop call sites in function.rs are routed through release_datastack_frame. Assisted-by: Claude * Stage exact-args call arguments in stack slot buffers CallPyExactArgs, CallBoundMethodExactArgs and CallAllocAndEnterInit no longer collect popped arguments into a per-call Vec (plus a second Vec for self-prepending). Arguments are popped into a fixed-size Option<PyObjectRef> slot buffer (CallArgBuffer, 8 inline slots, heap fallback for larger arities) and moved into fastlocals via the new invoke_exact_args_slots / a take() iterator. - prepare_exact_args_frame now accepts an ExactSizeIterator of args - specialization_run_init_cleanup_shim takes the slot buffer and fills slot 0 with new_obj, dropping one redundant clone - LoadAttrGetattributeOverridden, LoadAttrProperty and BinaryOpSubscrGetitem pass inline slot arrays instead of vec![] Assisted-by: Claude * Reduce allocations in generic call paths - FuncArgs::prepend_arg: use reserve instead of reserve_exact so exact-capacity vectors do not realloc on every prepend. - IntoFuncArgs::into_method_args: build the final args vec once with capacity len + 1 instead of prepending into a full vector. - PyType::call: skip cloning FuncArgs when no init slot can run after slot_new (no init slot, not `type`, and slot_new is not new_wrapper). Assisted-by: Claude * Skip redundant exc_info restore on frame exit with_frame_impl saves the current exc_info slot value and restores it when the frame exits. When the slot still holds the same value, the restore rewrites the slot and recomputes the thread-exception mirror for no effect. Add restore_exception, which compares the slot against the saved value by pointer identity and skips the store when they match. The saved value is a strong reference held for the whole frame scope, so the pointed-to object cannot be freed and its address reused while the frame runs, making the pointer comparison free of ABA. Assisted-by: Claude * Apply rustfmt to gc_state.rs Assisted-by: Claude * Avoid empty FuncArgs clone in PyType::call Cloning args for the init call clones the kwargs map even when args is empty, which shows up in no-argument instantiation profiles. Prepare the init-call args before slot_new: a default FuncArgs when args is empty (indistinguishable from a clone of empty args), the existing clone otherwise. The empty check also keeps the init-slot load of the clone-elision path off the no-argument call path. Assisted-by: Claude * Push freelist husks only after tp_clear and child drops default_dealloc pushed the object onto the thread-local freelist before running clear_fn. Payloads that drop children inside clear (Frame) can run __del__ there, and a reentrant allocation could pop the husk and overwrite its payload while clear_fn still held a &mut borrow of it. Tuples had the same window through the extracted-edges drop, which ran after the push. Reorder default_dealloc to clear, drop the extracted children, and only then attempt the freelist push, so the husk becomes reusable only when no borrows into the payload remain. The tuple freelist bucketed husks by element count, which required reading the payload during push; after this reordering the elements are already cleared. PyInner<PyTuple> is a fixed-size allocation (the elements box is dropped and replaced on reuse), so replace the per-size buckets with the shared single-list FreeList. Remove the now-unused pyinner_layout helper. Assisted-by: Claude * Resolve __set__ and __delete__ together for the descr_set slot The descr_set slot serves both __set__ and __delete__, but the TpDescrSet accessor resolved only the single modified name and fell back to MRO inheritance on delete. Deleting one of the pair could disable the surviving operation: after `del D.__set__`, an instance delete stopped calling the remaining __delete__. Resolve both names together like the TpSetattro accessor does: any Python-level definition selects the dispatching wrapper, matching native functions are stored directly, a single native function with the other name absent is stored directly, and the slot is inherited from the MRO only when neither name resolves. Assisted-by: Claude * Update type base on __bases__ assignment set_bases replaced bases and mro but never updated the stored base, so __base__ kept reporting the old value after reassignment and slot resolution (tp_new inheritance, set_new/set_alloc during init_slots) read the stale solid base. Change the base field to PyAtomicRef<Option<PyType>> so it can be swapped under the type lock while remaining lock-free for readers, and recompute it in set_bases with the same best_base validation type creation uses (BASETYPE flag, instance layout conflict among bases). The swapped-out base is parked in the frame's temporary refs; other references released inside the critical section are dropped after the lock is released. Also in set_bases: - remove this class from the old bases' subclass lists (pruning dead entries), so repeated assignment no longer accumulates duplicates - roll back bases, base, and all updated mros when the recursive mro update fails, instead of leaving the type half-reparented - fix the misformatted empty-tuple error message Remove the expectedFailure marker from test_unsubclassable_types, which now passes. Assisted-by: Claude * Fix rollback order, dead weakrefs, and lock-held drops in set_bases - Restore recorded mros in reverse on rollback so a class visited multiple times through diamond inheritance ends with its original mro instead of an intermediate one. - Skip dead weakrefs in the subclass list during the recursive mro update instead of panicking on upgrade. - Retire the replaced mros on the success path instead of dropping them while the type lock is held. Assisted-by: Claude * Reify number sub-slot wrapper once in update_one_slot The update_sub_slot! macro expanded the Python-method wrapper closure at both the own and inherited store sites. Each expansion is a distinct fn item, so a base and a non-overriding subclass stored wrappers with distinct addresses in unmerged debug builds. binary_op1 compares slot fn addresses to detect whether a subclass overrides the operator, so the inherited slot was misread as an override and C() // E() dispatched to __rfloordiv__ instead of __floordiv__. Bind the wrapper store in a single closure and call it from both branches so the fn item is reified once and the slot value stays identical across a base and its subclasses. Document the conservative-on-mismatch nature of the new_wrapper address guard in call_wrapped. Assisted-by: Claude * Restrict type_cache_after_fork visibility and guard type-cache reads type_cache_after_fork is only called from within the crate, so mark it pub(crate) to resolve the unreachable-pub warning. Add debug_assert_current_thread_attached at the has_name_in_mro lock-free type-cache read site, matching lookup_ref_and_version_interned, and gate the function on debug_assertions so it is not compiled unused in release builds where the call sites are elided. Assisted-by: Claude * Guard BinaryOpSubscrGetitem with the cached type version The specialized BINARY_OP_SUBSCR_GETITEM handler used the cached __getitem__ after checking only the function version, unlike the sibling specialized handlers which revalidate the type version tag first. Store the type version in the inline cache at specialization time and revalidate owner.class().tp_version_tag against it before using the cached function, deopting to the generic subscript path on mismatch. Assisted-by: Claude * Call __abstractmethods__ __len__ once in object.__new__ The abstract-method check invoked the user-visible __len__ twice: once via length_opt for the count and again while materializing the method names. Derive the count from the materialized list instead, so __len__ runs once. Assisted-by: Claude * Use i64 fast paths for specialized int add/sub/mul Rewrite execute_binary_op_int to box results through new_int via i64 checked arithmetic instead of raw BigInt ops with new_bigint. Add an int_mul helper and a shared int_fast_op that computes the i64 result and falls back to the BigInt operation on to_i64 or checked-op failure. Wire int_mul into both the specialized BinaryOpMultiplyInt handler and the generic execute_bin_op Multiply/InplaceMultiply path, gated on exact int operands so subclasses keep dispatching through _mul/_imul. Assisted-by: Claude * Use i64 fast paths for exact int floordiv and remainder Add floordiv_i64/mod_i64 computing i64 floor-division and divisor-signed remainder, guarding zero divisor and i64::MIN overflow by returning None. Wire them through int_floordiv/int_mod (shared int_div_fast_op boxes via new_int) into the generic execute_bin_op FloorDivide/Remainder and their Inplace variants, gated on exact int operands so subclasses and zero divisors fall through to the existing _floordiv/_mod/_ifloordiv/_imod slow path. Assisted-by: Claude * Skip trashcan and untrack for non-GC-tracked objects in dealloc default_dealloc read is_gc_tracked() only to decide untracking, and entered the trashcan recursion guard unconditionally. Non-GC objects (int, float, str, ...) own no child references that recurse during deallocation, so they need neither the trashcan nor untracking. Read is_gc_tracked() once and gate both trashcan begin/end and untrack on it, removing three thread-local accesses per non-GC object deallocation. Assisted-by: Claude * Merge trashcan depth and defer queue into one thread-local struct trashcan::end accessed two separate thread-locals (DEALLOC_DEPTH and DEALLOC_QUEUE) at the outermost deallocation. Combine both into a single `Trashcan` thread-local holding Cell-based depth and queue fields, so begin and end each reach their state through one thread-local access. The queue is set back before each deferred dealloc call so reentrant begin/end during draining never holds an outstanding borrow. Assisted-by: Claude * Check object layout compatibility on __bases__ and __class__ assignment Add a shared compatible_for_assignment helper that walks each type to the base that fixes its instance layout and rejects the assignment when the old and new layouts differ (basicsize, itemsize, member count, __dict__, __weakref__, and __slots__ names). Wire it into set_bases, which previously performed no layout check, and replace the inline check in __class__ assignment, which compared the two types directly and over-rejected a subclass that adds no layout. Enable test_descr.test_builtin_bases, which the new set_bases check passes. Assisted-by: Claude * Stop the world around GC pointer-reading phases The cycle collector reads each tracked object's interpreter state during reference subtraction, the reachability walk and the strong-reference snapshot, including the localsplus of frames other threads are executing. Those slots are written without synchronization, so the reads are a data race under threading. collect_inner now stops the world before taking the generation read locks and restarts it after the strong-reference snapshot, before the finalizer/weakref/tp_clear phases. A debug assertion checks that no frame on any thread's call stack was classified unreachable. Automatic collections from maybe_collect are deferred to the next bytecode safepoint via a new eval-breaker GC bit instead of running synchronously: a synchronous collection can hold an internal lock (e.g. the lazy frame locals cell) that another thread is blocked on with no way to reach a safepoint, deadlocking the stop. Hardens the stop-the-world machinery for these frequent, concurrent GC stops: attach_thread now honors a pending stop after re-attaching so a thread doing rapid allow_threads calls cannot run past the requester; stop_the_world completion is level-triggered on all-threads-suspended rather than an edge-triggered countdown; and the thread-start started/ready handshakes detach while waiting so the waiter is parkable. Updates the Frame and PyRwLock/PyMutex traversal SAFETY comments to state the actual invariant. Assisted-by: Claude * Add threaded GC vs executing-frame stress snippet Workers churn frame state (recursion, generators, frame cycles) while a collector loops gc.collect() and an introspector walks live frame objects. Exercises the stop-the-world barrier around GC traversal. Assisted-by: Claude * Serialize fork and GC stop-the-world requesters fork() (posix before/after-fork) and the cycle collector both drive the single StopTheWorldState. With no mutual exclusion their requester word and suspension countdown could interleave and be clobbered, so the completion check never converged and a requester waited on itself forever (reproducible parent-side hang when forking with GC enabled). Add one exclusion held for the whole stop->start span of either requester: stop_the_world acquires it before any stop bookkeeping and start_the_world/reset_after_fork release it. The acquire is park-friendly (poll try-lock and honor a pending suspend between tries) so a requester blocked behind an active stop can still be force-parked instead of deadlocking the active requester. The acquirer holds no other lock while spinning. Also correct the PyRwLock traverse SAFETY note: a failed try_read may mean a force-parked thread holds the write lock; skipping is safe because under-traversal only over-approximates liveness. Document the residual gc.collect()-under-a-non-generation-lock exposure at the collect_inner barrier. Assisted-by: Claude * Add fork under concurrent GC stop-the-world snippet Worker threads allocate cyclic garbage with GC enabled while the main thread forks repeatedly and each child collects. Exercises the fork/GC stop-the-world exclusion; the allocation rate is throttled so a collection stays cheap in unoptimized builds. Assisted-by: Claude * Detach while acquiring the import lock The global import lock is held across bytecode by the importlib bootstrap, so its holder can be parked at a safepoint mid-hold. Acquiring it while attached let another thread block attached on the lock, so a stop-the-world requester could wait forever for that attached thread to suspend while the holder stayed parked. Wrap IMP_LOCK acquisition in allow_threads in both _imp.acquire_lock and the pre-fork acquire_imp_lock_for_fork so the wait honors stop-the-world requests. Correct the acquire_exclusion comment: a spinning requester may hold IMP_LOCK (fork) or the collecting mutex (GC); safety relies on those never being acquired attached-blocking by another thread. Assisted-by: Claude * Add concurrent-import vs GC deadlock snippet Two threads re-import modules (contending the import lock) while a third storms the cycle collector and a fourth allocates cyclic garbage. Regressed as a hang before the import lock acquisition was made park-friendly. Assisted-by: Claude * Create call frames untracked and track generators explicitly Add PyPayload::NEW_REF_UNTRACKED (default false, true for Frame) so PyRef::new_ref skips auto-tracking ordinary call frames in the GC. Generator/coroutine/async-generator frames are tracked explicitly in invoke_with_locals before their generator back-reference is installed. run_frame debug-asserts that a datastack frame is untracked on entry. Assisted-by: Claude * Track escaped call frames lazily at datastack release Rewrite release_datastack_frame around the invariant that a datastack frame is never GC-tracked while it runs: strong_count() == 1 means the frame never escaped, so drop localsplus in place without touching the GC; strong_count() > 1 means it escaped, so materialize localsplus onto the heap and then track the frame. This removes the untrack and the untrack-recheck dance from the common non-escaping path. Assisted-by: Claude * Guard the tracked-frame localsplus invariant Document at Frame::traverse that references to a frame are always recorded as graph edges, so the collector reads a frame's localsplus only when the frame is itself a tracked candidate. Add debug assertions at both frame track sites (escaped datastack frames and generator frames) that a frame is heap-backed before it is tracked, so a collector never reads data-stack-resident, still-mutating storage. Assisted-by: Claude * Reword frame/dealloc invariant comments and drop needless borrow - frame.rs: replace the task codename in the tracked-frame localsplus invariant comment with a description of the collector-vs-executing-frame behavior. - object.rs: remove needless borrow on current_cls in the __class__ assignment compatibility check. - core.rs: rewrite the default_dealloc trashcan/untrack-skip comment to state the actual invariant, which now covers untracked non-escaped frames releasing at interpreter depth with bounded recursion. Assisted-by: Claude * Move type SetAttr slot rewrite inside the type lock and tighten cache reads Run update_slot inside the same with_type_lock transaction as modified_inner and the attributes dict mutation, so the version invalidation, dict change, and slot-table rewrite are published together. Load init_version and getitem_version with Acquire in the specialization cache readers to pair with the Release stores in the writers. Assisted-by: Claude * Capture the type version before reading mutable slots in specializers specialize_load_attr, specialize_store_attr, specialize_to_bool, and the CallAllocAndEnterInit path of specialize_call read the version tag with version_for_specialization before inspecting getattro, setattro, the bool/len slots, and tp_new/tp_alloc, so a concurrent install of the corresponding dunder invalidates the version the specialization is cached against. In the BinaryOpSubscr __getitem__ path, check the HEAPTYPE and eval-frame gates before lookup_ref_and_version_interned, which takes the global type lock and may allocate a version tag. Assisted-by: Claude * Use _get_method_dict for the test_type check in the test runner Replace the direct __func__.__dict__ access with the _get_method_dict helper so plain functions without __func__ do not raise AttributeError. Assisted-by: Claude * Fix lint hooks: cspell dictionary entries, spelling fix, formatting Add qsbr to the rustpython dictionary and reborrows/reparenting to the top-level word list. Rename oldto/newto locals to old_to/new_to. Fix Stabilise -> Stabilize typo in a frame.rs comment. Apply cargo fmt to object.rs, type.rs, and frame.rs, and ruff format/check fixes to two extra_tests snippet files. Assisted-by: Claude * Rebuild all slots for type and descendants on __bases__ reassignment Add PyType::update_all_slots, which invalidates version tags and iterates the full SLOT_DEFS name table calling update_slot::<true> for each distinct name. Unlike init_slots, which is additive and driven only by dunder names present in the current MRO, this resets a slot whose method left the MRO instead of leaving a stale dispatcher pointer. Call it from set_bases in place of the previous modified_inner + init_slots pair, so reassigning __bases__ rebuilds slots for the type and every descendant. Add extra_tests/snippets/type_bases_slot_rebuild.py covering removed-method resets on zelf and deep descendants, the wrong-target switch, __getattr__, the added-method mirror, and a swap-away-and-back round trip. Assisted-by: Claude * Derive the thread-local frame stack from the frame chain Remove the per-VM `frames` Vec. current_frame, sys._getframe, sys._getframemodulename, frame.f_back, sys.monitoring re-instrumentation, gc.get_referrers, faulthandler stack dumps and the post-fork slot rebuild now walk the signal-safe CURRENT_FRAME/`previous` chain instead. Add `Py::from_payload_ptr` to recover a frame object from a chain pointer. The cross-thread `ThreadSlot::frames` registry (sys._current_frames, cross-thread f_back, GC stop-the-world assertion) is unchanged. Assisted-by: Claude * Inherit sub-slot fallback into the field being resolved update_one_slot's number/sequence/mapping fallback inherited via the accessor's default field. Left and right binary ops (add/right_add) share one accessor but occupy distinct fields, so resolving an absent right op or deleting it reset the left op's field, dropping a still-defined __add__ dispatcher. Inherit the exact field under resolution instead. Assisted-by: Claude * Gate type_cache_after_fork to its fork caller and use Self in downcast type_cache_after_fork is only called from the unix fork path, so gate it with all(feature = "host_env", unix) to match the caller and avoid a dead-code error on non-unix targets. Replace the explicit PyType with Self in the modified_inner downcast. Assisted-by: Claude * Unmark test_attr and test_method_call_error in test_monitoring Both TestLoadSuperAttr tests now pass; remove their expectedFailure markers. Assisted-by: Claude * Run tp_new specialization __init__ without a trampoline frame CallAllocAndEnterInit ran __init__ inside a synthetic init-cleanup shim frame whose code carried the __init__ name. Since the thread frame stack is derived from the frame chain, that shim frame was visible to sys._getframe, f_back walks, traceback construction and inspect.stack / inspect.trace. Its code object has empty co_positions, so a stack walk that reached it raised StopIteration inside inspect._get_code_position, cascading into unrelated failures (test_inspect trace/stack/frame, asyncio source traceback). Call __init__ directly via run_frame, enforce the __init__() should return None contract inline, and drop the shim: the init-cleanup code object, its builder, with_frame_untraced, monitoring_disabled_for_code, and the extra-frame datastack/recursion budget. Removing the second frame per construction also cuts the specialization's per-call cost. Assisted-by: Claude * Replace per-call thread-frame mutex with an atomic top-of-stack (unix) On unix threading builds, publish each thread's top Python frame in a single relaxed AtomicPtr store from set_current_frame instead of pushing onto a parking_lot::Mutex<Vec<FramePtr>> per call. Cross-thread readers (sys._current_frames, cross-thread f_back, faulthandler.dump_traceback, the GC unreachable debug-assert) run under stop-the-world and walk the published top frame down the Frame::previous chain; the owning thread is then parked at a safepoint, so the pointer and the frames it reaches are quiescent and alive. The faulthandler watchdog is a plain OS thread that cannot stop-the-world, so it walks the chain lock-free and best-effort. Non-unix threading builds have no stop-the-world and keep the existing mutex-guarded frame stack unchanged. Assisted-by: Claude * Skip exc_info save/restore for callees that never touch the slot with_frame saves and restores the shared exc_info slot around every Python call to contain frames that leave it unbalanced. Cache a has_exc_handling bit on PyCode at creation, set when the bytecode contains any opcode that calls vm.set_exception (PushExcInfo, PopExcept, CheckEgMatch, EndAsyncFor, InstrumentedEndAsyncFor). A callee whose code has none of these cannot mutate the slot, so the save and restore are skipped for it. Generators go through resume_gen_frame and are unaffected. Assisted-by: Claude * Return a write-through FrameLocalsProxy from frame.f_locals Optimized (function) frames now expose `f_locals` as a `FrameLocalsProxy` implementing PEP 667 semantics instead of a cached snapshot dict: - reads go live through the fast-local slots; each access mints a fresh proxy; keys that do not name a fast local are stored in a per-frame `f_extra_locals` side dict and folded into `locals()`. - writes to a fast-local key store into the slot (or its cell) in place; deleting a fast local raises ValueError; extra keys delete normally. - full mapping protocol: keys/values/items (lists), get/pop/setdefault, update (dict or FrameLocalsProxy only), __or__/__ior__/__ror__ (dict result), copy (plain dict), __reduce__ blocks pickling/copy, repr with recursion guard, mapping-pattern and Mapping ABC support. Class/module/exec frames keep returning their namespace mapping directly. Cross-thread access to a frame running on another thread still raises RuntimeError. A closed generator now keeps its frame locals when a durable frame reference escaped (f_locals proxy, sys._getframe, f_back), matching take_ownership; the escape is tracked with a per-frame flag. The snapshot-then-fold locals_to_fast/locals_dirty write-back is retired since proxy writes reach the slots directly. Assisted-by: Claude * Retain the caller frame so f_back resolves after it returns When a frame escapes its execution (referenced through a traceback, `sys._getframe`, `f_locals`, ...), capture a strong reference to its caller at release time. `f_back` consults it once the caller has left the live frame chain, so the Python-visible frame chain survives return. The retained reference is a GC-traversed edge and is cleared by `frame.clear()`, so ancestor chains stay collectable. Assisted-by: Claude * Fix debug-build native stack overflow on deep recursion Make check_c_stack_overflow one-sided (trip whenever the stack pointer is below the soft limit) so a single native frame larger than the margin cannot step past the danger band undetected. Raise the debug STACK_MARGIN_BYTES from 4096 to 16384 words so the margin exceeds a single debug interpreter frame, leaving headroom to raise RecursionError. Release margin unchanged. Clamp the soft-limit margin to half the stack so small explicit thread stacks do not get a soft limit above their stack top. Assisted-by: Claude * Allocate exception instance __dict__ lazily Exception construction went through into_ref_with_type, which eagerly allocated an empty instance dict for every HAS_DICT type. Add into_ref_with_type_lazy_dict, which builds the instance with an unallocated dict slot, and route the four exception construction sites (PyBaseException, PyOSError, OSErrorBuilder, PyBaseExceptionGroup) through it. The dict now materializes on first attribute write or __dict__ access via the existing get_or_insert path. add_note and PyImportError::slot_init now obtain the dict through object_get_dict so they materialize it instead of assuming it exists. A freshly constructed exception no longer reports an empty dict in gc.get_referents, matching the reference interpreter. Assisted-by: Claude * Allocate exception __dict__ lazily in vm.new_exception Route vm.new_exception() through into_ref_with_type_lazy_dict so internally raised exceptions (new_type_error, new_value_error, etc.) start without an instance dict, matching the slot_new path. The dict is materialized on the first attribute write or __dict__ access. Assisted-by: Claude * Validate FrameLocalsProxy.update() arguments Reject keyword arguments and require exactly one positional argument, raising TypeError with the "takes no keyword arguments" and "takes exactly one argument (N given)" messages. Assisted-by: Claude * Address review nits in frame and faulthandler - Drop stale vm.frames reference from the release_datastack_frame uniqueness argument. - Assert has_exc_handling when unwinding an Except-typed stack slot, documenting the invariant that guards the shared exc_info write. - Truncate the specialized __init__ return-type name to 200 chars, matching the unspecialized wrapper. - Reword two comments to describe behavior without prose references to CPython. Assisted-by: Claude * Use scopeguard for start_the_world in faulthandler dump_all_threads Wrap the unix stop-the-world registry walk in a scope with scopeguard::defer! so start_the_world runs on panic, matching the f_back and get_all_current_frames sites. Add scopeguard to the stdlib dependencies. Also correct the restore_exception doc comment to name with_frame after the rename. Assisted-by: Claude * Gitignore docs/superpowers Assisted-by: Claude * Rename type_bases_slot_rebuild.py to builtin_type_bases.py Match the builtin_* naming convention of extra_tests/snippets. Assisted-by: Claude * Apply rustfmt, ruff, and cspell lint fixes Reformat with rustfmt, fix import spacing in builtin_type_bases.py with ruff, and add "pointee" to the cspell word list. Assisted-by: Claude * Gate unix-only QSBR methods to their call sites `online`, `drain_all`, and `reset_after_fork` are called only from unix code (thread attach/detach, post-fork reset), and `offline` from unix code plus a unit test. Gate them with matching cfg so `-D dead_code` does not fire on non-unix targets. Assisted-by: Claude * Visit the function closure tuple as a GC edge PyFunction::traverse visited the cells inside the closure tuple instead of the tuple object itself, so the tuple's reference from the function was never subtracted during cycle collection. A closure tuple that reached back to its function (or, through a frame retained by f_back, to a Thread) was stranded as a false GC root and never collected, leaking the whole cycle. Visit the tuple itself, matching clear(). Assisted-by: Claude * Apply formatting hook fix to builtin_type_bases.py Assisted-by: Claude * Unmark asyncgen finalization-by-gc tests in test_base_events test_asyncgen_finalization_by_gc and test_asyncgen_finalization_by_gc_in_other_thread now pass; GC finalizes the async generators. Assisted-by: Claude * Unmark test_sni_callback_refcycle in test_ssl The servername-callback reference cycle is now collected by GC. Assisted-by: Claude * Widen GC stop-the-world gates from unix-only to all threading builds Change `cfg(all(unix, feature = "threading"))` to `cfg(feature = "threading")` on the stop-the-world machinery so it also compiles and runs on non-unix threading builds: - StopTheWorldState, its stats, stw_trace, and the stop_the_world field - ThreadSlot state/stop_requested/thread fields and their initializers - wait_while_suspended/attach_thread/detach_thread/suspend_if_needed/do_suspend, allow_threads, stop_requested_for_current_thread, and the enter_vm / VmBootstrapGuard / attach_current_thread / release_current_thread / cleanup attach-state wiring - eval_breaker_tripped, check_signals, run_scheduled_gc, signal GC_BIT / schedule_gc / take_gc_scheduled, and the frame.rs safepoint call - CollectStopTheWorld and its use in collect_inner - QSBR::online/offline, now called from attach/detach on all threading builds - debug_assert_current_thread_attached and its type-cache call sites maybe_collect defers auto-collection to the bytecode safepoint on every threading build instead of only unix; non-threading builds keep the inline collect. stw_trace writes to std stderr on non-unix. top_frame publishing (CURRENT_TOP_FRAME_SLOT, set_current_frame), the frame-walk debug assert in collect_inner, and the fork reinit helpers remain unix-only; non-unix keeps ThreadSlot::frames for introspection. Assisted-by: Claude * Detach current thread around blocking _winapi/_overlapped waits Wrap the blocking Windows wait calls in `vm.allow_threads` so the calling thread transitions ATTACHED -> DETACHED for the duration of the wait: - _winapi: WaitForSingleObject, WaitForMultipleObjects, BatchedWaitForMultipleObjects, ConnectNamedPipe, ReadFile, Overlapped.GetOverlappedResult - _overlapped: Overlapped.getresult These previously blocked while ATTACHED, so a stop-the-world requester could never suspend the thread and spun in its wait loop indefinitely. * Format WaitForMultipleObjects allow_threads closure * Treat concurrent sni_callback removal as no-op in invoke_sni_callback * Assert capi refcount on a fresh mortal list instead of the int type object The refcount test asserted exact incref/decref deltas on PyInt's shared type object. That object's reference count is perturbed by the other capi tests running in parallel, and is immortal under some interpreter configurations, so the deltas were not reliably +1/-1. Assert them on a freshly created, uniquely owned list whose reference count is private to the test and mortal. Assisted-by: Claude * Traverse and GC-track PyOSError instances The `#[pyexception]` struct macro now forwards a `traverse` option to the generated `#[pyclass]`, and `ExceptionItemMeta` accepts the `traverse` key. `PyOSError` is marked `traverse = "manual"`, so `HAS_TRAVERSE` is true and OSError-family instances are tracked at creation and traversed by the collector. `PyOSError::traverse` now visits the underlying `PyBaseException` (traceback, cause, context, args) instead of `PyException::try_traverse`, which was a no-op because `PyException` has `HAS_TRAVERSE = false`. * Unmark test_blockingioerror in test_io The BlockingIOError reference cycle is now collected by GC.

ctypes: unify the foreign-call path on a single host_env call() API (#8235)
* host_env: add unified high-level `call` foreign-call API
Add a libffi-hiding foreign-call entry point that takes ctypes type codes
and recursive layouts plus raw buffers instead of libffi `Type`/`Arg`, to
become the single call path for the VM `_ctypes` (a later change) and other
consumers. Also bring in the `callproc_simple` helper so this host_env copy
stays byte-identical to the pyre-dev copy during the migration.
- `CTypeLayout` (Simple/Pointer/Struct/Union/Array/Opaque) with `size()` and
an internal libffi-type lowering built on `ffi_type_for_layout`.
- `CallArg` (Typed/Int/Double/Pointer/Aggregate), `CallRet`
(Void/Code/Pointer/Aggregate), `CallOptions` (use_errno/use_last_error),
`CallValue` (Void/Scalar/Pointer/Aggregate), and `CallError`.
- `call(addr, &[CallArg], CallRet, CallOptions) -> Result<CallValue,
CallError>`, built on the existing `Cif`/`ffi_*` primitives: the errno /
last-error swap wraps only the raw call, and by-value aggregate arguments
and returns go through `Cif::call_return_into`.
- 16 ABI unit tests over local `extern "C"` functions: scalar parity,
by-value struct / nested / array-in-struct / {f32,f32} / large-struct
arguments, small / odd / large struct returns, union size, the errno
window, and the null-pointer / unknown-code / short-buffer errors.
`callproc` and `callproc_simple` are left in place; both are removed once the
migration onto `call` completes.
Assisted-by: Claude
* _ctypes: route the VM call path through host_env call()
Replace the VM's direct libffi `Type`/`Arg` marshalling with the unified
host_env `call` entry point. Behavior is preserved on the tested paths:
structs and unions still pass by pointer and struct returns still use the
register-size approximation (passing/returning aggregates by value is a
later change).
- base.rs: `FfiArgValue` → `CArgValue` (Typed{code,bytes}/Int/Double/Pointer)
with `as_call_arg()`; the paramfunc producers emit `CArgValue`, snapshotting
buffer bytes at conversion time so no lock is held across the call.
- _ctypes.rs: `CArgObject` carries `value: CArgValue` plus a `keep` slot for
the from_param z/Z/P null-terminated-copy keepalive that no longer rides in
the value; `PyCArg` repr reconstructs the scalar for identical output; byref
updated.
- simple.rs: `to_ffi_value` → `to_carg_value`; from_param emits `CArgValue`
and its keepalive.
- function.rs: `Argument{value, keep}`; `ArgumentType` yields a `CArgValue`
(with the "unsupported argument type" check moved up front); `CallInfo`'s
return fields collapse to `RetSpec` (Void/Pointer/Code) reproducing the exact
return type and result dispatch; `ctypes_callproc` builds `CallArg`/`CallRet`/
`CallOptions` and invokes `host_env::ctypes::call`; the errno/last-error swap
moves into `CallOptions` (the `with_swapped_*` wrappers are removed);
`convert_raw_result` consumes `CallValue`.
- extra_tests/snippets/stdlib_ctypes_calls.py: libc calls over the live FFI
path (abs/strlen/sqrt, c_char_p/c_void_p returns, a use_errno round-trip);
output matches CPython.
Two intentional deltas: a NULL function pointer now raises ValueError instead
of a debug assertion, and a c_char passed positionally without argtypes now
zero-extends via its type code rather than sign-extends via the old tag path,
which also makes it agree with the with-argtypes path.
The old host_env `callproc`/`ffi_*` and `StgInfo`'s libffi field types remain
for now; they are removed when by-value aggregates land.
Assisted-by: Claude
* _ctypes: pass and return structs and unions by value
Flip aggregate arguments and returns from the pointer / register-size
approximation to true by-value passing through the host_env `call` entry
point, and carry the driving layouts as host_env `CTypeLayout`.
- base.rs: `StgInfo.ffi_field_types: Vec<FfiType>` becomes
`field_layouts: Vec<CTypeLayout>`, still built incrementally from the base
class so struct inheritance is reflected. `StgInfo::to_ffi_type()` is
replaced by a `type_layout(ty, &stg, vm)` helper that reads a type's own
layout (aggregates from `field_layouts`, arrays recurse into the element
type, simple types from their `_type_` code); it takes the already-borrowed
`StgInfo` so it never re-locks the type. `CArgValue` gains an
`Aggregate { layout, bytes }` variant lowering to `CallArg::Aggregate`, and
`struct_union_paramfunc` snapshots the instance bytes into it (tag 'V').
- structure.rs / union.rs: collect each field's `type_layout` into
`field_layouts` and store it on the finalized `StgInfo`.
- function.rs: `convert_object` passes a struct/union argument by value
(snapshot bytes + argtype layout); a `byref()` result is still a pointer.
`RetSpec` gains `Aggregate(CTypeLayout)`; `compute_ret_spec` returns it for
a struct/union restype; `ctypes_callproc` lowers it to `CallRet::Aggregate`.
`convert_raw_result` now drops the restype `StgInfo` read guard before
constructing the result instance: instance construction write-locks the
type's `StgInfo` to finalize it, which otherwise self-deadlocks against the
held read guard (latent since the register-size return path, unreachable
until a struct was actually returned by value).
- _ctypes.rs: a 'V' cparam now reprs as `<cparam 'V' at 0x..>` (the
object-address default), matching PyCArg_repr; the aggregate `CArgValue`
routes through that arm.
- extra_tests/snippets/stdlib_ctypes_byvalue.py: div/imaxdiv struct returns
(8- and 16-byte), inet_ntoa struct and union arguments, with and without
argtypes; output matches CPython. Also sorts the imports in the sibling
stdlib_ctypes_calls.py snippet (ruff isort).
`_pack_` / `_swappedbytes_` layouts stay approximate — `CTypeLayout` carries
no explicit field offsets, as the previous libffi field-type path did not
either. host_env is untouched, so both `ctypes.rs` copies stay byte-identical.
test_ctypes is unchanged at run=322 skipped=58.
Assisted-by: Claude
* host_env: remove the pre-`call` foreign-call scaffolding
With the VM `_ctypes` and pyre both routed through `call`, delete the
foreign-call paths and libffi-type builders that no longer have a consumer:
- `callproc` (the low-level libffi `Vec<Type>` / `&[Arg]` entry) and its
`CallResult` return type plus `call_result_bytes`.
- `callproc_simple` and its `SimpleArg` / `SimpleRestype` / `SimpleCallError`
types (the pointer-only slice added for pyre's first cut), and the
`lookup_function_symbol_addr_str` helper, along with their tests.
- `ffi_type_for_layout` + `CTypeParamKind`, `ffi_type_from_format`,
`ffi_type_from_tag`, and `ffi_type_for_return_size` — the aggregate/simple
libffi-type builders the old marshalling used. `call` and `CTypeLayout`
build their own libffi types from `ffi_type_from_code` and the small
`ffi_{pointer,byte_struct,repeat,void,i32,f64}_type` helpers, which stay.
`simple_type_chars` stays (still used by pyre's simple-type validation). The
`call` doc no longer references `callproc_simple`. A stale comment in the VM's
result decoder that named `call_result_bytes` is reworded.
host_env drops from 4051 to 3535 lines; the `call` ABI unit tests remain
(24 tests). test_ctypes is unchanged at run=322 skipped=58.
Assisted-by: Claude
* host_env: read `call` scalar returns as a full register, use `add_i32`
`call` read `Code` returns through `low::ffi_arg`. The `libffi_sys`
binding types `ffi_arg` as `c_ulong`, which is 4 bytes under LLP64
(Windows x64), so `low::call` truncated 8-byte returns (`q`/`Q`/`d`) to
the low 4 bytes. `calls_f64_scalar` and `passes_large_struct_by_value`
failed on windows-2025. Read a full register (`u64`) instead;
`decode_type_code` still slices the leading bytes each type code needs.
No change on LP64, where `ffi_arg` is already 8 bytes.
Add `typed_two_scalar_args`, which calls the previously-unused `add_i32`
ABI helper (two-argument scalar path); the helper tripped `-D warnings`
dead-code on clippy.

* _ctypes: skip the by-value snippet on Windows
`stdlib_ctypes_byvalue.py` reaches libc through `CDLL(None)` and calls
`div`/`imaxdiv`/`inet_ntoa`, none of which resolve that way on Windows,
so the snippet aborted on windows-2025. Guard it like
`stdlib_ctypes_calls.py`: print "OK" and exit before touching `CDLL`.
The by-value path is covered on Windows by test_ctypes.
Assisted-by: Claude
* _ctypes: keep the converted argument alive for by-value aggregates
The by-value struct/union argument path snapshotted the instance bytes
and returned `None` for the keep-alive slot, dropping the `from_param`
result before the foreign call. When the snapshot embeds pointers into
buffers owned by that object's keep-alive set, the call could read freed
memory. Return the converted instance as the keep-alive owner.
Assisted-by: Claude
* host_env: avoid indexing an empty by-value aggregate buffer in `call`
A zero-sized `Structure`/`Union` argument reaches the aggregate lowering
with `layout.size() == 0` and an empty buffer, which passed the
`buffer.len() < expected` check and then panicked on `&buffer[0]`. Use
`buffer.first().unwrap_or(&0u8)`; libffi reads nothing for a zero-size
type.

Implement round-half-even float.fromhex in common float_ops (#8234)
* Add round-half-even hex float parser to common float_ops Add float_ops::from_hex returning Result<f64, HexFloatError>, which parses the coefficient and exponent, rounds round-half-even over the full exponent range, and detects overflow. Route float.fromhex through it: raise OverflowError for values too large to represent and ValueError for invalid input. Remove the expectedFailure on test_from_hex.

more hostenv isolation (#7932)
* Move which crate dependency from vm to host_env
Add host_env::fs::which wrapper and update getpath.rs call site.
* Move readline module from vm to host_env
Move crates/vm/src/readline.rs to crates/host_env/src/readline.rs and
re-export it from rustpython_vm::readline. Move rustyline dependency
from vm to host_env. Drop the host_env feature gates on history I/O
inside the moved module.
* Move gethostname and mac_address dependencies from stdlib to host_env
Add host_env::socket::hostname and host_env::socket::mac_address
wrappers. Update _socket.gethostname and _uuid.get_node_id call sites.
* Re-export libc constants and types through host_env
Move direct libc constant and type references in stdlib (faulthandler,
fcntl, multiprocessing, posixshmem, select, syslog) to use host_env
re-exports. Replace libc::c_int and libc::c_uint in stdlib with
core::ffi equivalents.
* Re-export mmap libc constants through host_env
Move direct libc MADV_*, MAP_*, PROT_*, EOVERFLOW references in
stdlib::mmap to host_env::mmap re-exports. Replace libc::c_int with
core::ffi::c_int.
* Re-export locale and termios libc constants through host_env
Move direct libc LC_*, ABDAY_*, ABMON_*, TIOC*, FIO* and related
constants in stdlib::locale and stdlib::termios to host_env
re-exports. Replace libc::c_char in stdlib::locale and
stdlib::openssl::cert with core::ffi::c_char.
* Replace libc c-types and FILE wrappers in openssl with host_env
Replace libc::c_int, c_long, c_uchar, c_uint, c_ulong, c_void,
c_char in stdlib::openssl with core::ffi equivalents. Replace
libc::ENOENT with host_env::errno::errors::ENOENT. Add
host_env::fileutils::{CFile, fclose} and route the load_dh_params
fclose call and PEM_read_DHparams FILE pointer type through them.
* Fix Windows build: expose EOVERFLOW, SIGSEGV, SIGFPE on Windows
host_mmap::EOVERFLOW and host_faulthandler::{SIGSEGV, SIGFPE}
re-exports were gated to cfg(unix) but stdlib uses them from Windows
and platform-agnostic code paths.
* Re-export remaining libc types and constants through host_env
Move direct libc references in stdlib (resource, posixsubprocess,
grp, socket) to host_env re-exports. Replace libc::c_long,
libc::c_longlong, libc::c_char in stdlib::socket with core::ffi
equivalents. Add resource::{RLIMIT_*, RUSAGE_*, c_long, rlim_t,
rlimit, timeval}, posix::{c_char, pid_t}, grp::gid_t, and
socket::{AF_*, SOCK_STREAM, sa_family_t, socklen_t, sockaddr_*}
re-exports.
* Move socket2 and dns-lookup dependencies from stdlib to host_env
Re-export socket2 as host_env::socket::raw and dns-lookup as
host_env::socket::dns. Update _socket call sites to route through
host_env aliases.
* Move system-configuration dependency from stdlib to host_env
Re-export the macOS system-configuration crate as
host_env::system_configuration and update _scproxy call sites.
* Restrict CAN/ALG sockaddr structs to target_os linux
libc on Android (bionic) does not define sockaddr_can, so importing it
for target_os = "android" fails to compile. Keep AF_ALG/AF_CAN for both
linux and android, and gate sockaddr_alg/sockaddr_can to linux only.

Fix decompose_float subnormals, float format grouping/empty type; add HashSecret::from_keys (#8232)
* common: fix decompose_float for subnormal inputs Subnormals carry a biased exponent of 0 and no implicit leading mantissa bit, so the bit-twiddling frexp misread them: hash(5e-324) returned 8404992 instead of CPython's 16777216. Scale subnormals into the normal range by 2**54 (exact) before decomposing and fold the shift back into the returned exponent. Adds a frexp-contract unit test over normals, subnormals, and boundary values. Assisted-by: Claude * common: add HashSecret::from_keys HashSecret's fields are private and the only constructor derives k0/k1 from a u32 seed, so an embedder cannot reproduce a fixed keying (e.g. a deterministic PYTHONHASHSEED=0-style run). Add a const constructor taking explicit SipHash keys; the seeded path is unchanged. Assisted-by: Claude * common: fix float format grouping and empty presentation type Thousands grouping split the magnitude only on '.', so exponent and percent tails received separators (format(1e20, ',e') gave '1e+,20'-class corruption). Group only the leading integer digits for interval-3 output; hex/octal/binary keep whole-magnitude grouping. Empty presentation type: with a precision, clamp it to at least 1 and restore a trailing '.0' on integer-looking results (Py_DTSF_ADD_DOT_0); without one, alternate form now inserts the forced decimal point before an exponent instead of appending it. Verified byte-identical to CPython 3.14 over a hash/format differential battery; test_format, test_float, test_fstring, test_hash pass. Assisted-by: Claude * common: satisfy rustfmt and clippy in new hash/float tests - float_ops: use core::f64::consts::PI in the frexp-contract battery (clippy::approx_constant) - hash: rewrite the keyed_hash test via BuildHasher::hash_one (clippy::manual_hash_one) - rustfmt the new float_ops/hash/format test modules Assisted-by: Claude * common: add DTSF to format.rs spell-checker ignores Assisted-by: Claude |

unicode crate (#8211)
* Extract unicodedata core into rustpython-unicode crate
Move the vm-free Unicode character database access — the generated UCD 3.2.0 /
latest tables, their build-time generation, and the icu4x/unicode_names2 lookups
for category/bidirectional/combining/east_asian_width/mirrored/decomposition/
normalize/is_normalized/digit/decimal/numeric/name/lookup — into a new leaf crate
over char/CodePoint/&Wtf8. stdlib/unicodedata.rs keeps the UCD pyclass binding: it
extracts the code point, boxes results, and maps errors. The unicode data files,
build.rs table generation, and the icu_properties/icu_normalizer/unicode_names2
dependencies move out of stdlib.
Assisted-by: Claude
* Route str predicates, casefold, and printable through rustpython-unicode
Add classify/case/identifier modules to the shared crate over char/&str/&Wtf8:
isalpha/isalnum/isdecimal/isdigit/isnumeric/isspace/isprintable classification,
XID identifier predicates, and full-mapping casefold. vm/builtins/str.rs and
literal/char.rs now call these instead of icu_properties/icu_casemap directly.
String-level iteration with final-sigma handling (lower/upper/title/capitalize,
islower/isupper) stays in the runtime.
Assisted-by: Claude
* Route sre_engine char classes through rustpython-unicode
Add the regex module with the SRE character-class and case predicates
(is_word/is_space/is_digit, is_uni_* Unicode variants, ascii/locale/unicode case
folding). sre_engine/string.rs now forwards to it, keeping its public API and
behavior identical — including the ASCII-only is_uni_digit and the hardcoded
is_uni_space table.
Assisted-by: Claude
* Route \N{} name lookups through rustpython-unicode
codegen/string_parser.rs (\N{...} escapes) and common/encodings.rs (the
namereplace error handler) now resolve character names via rustpython-unicode
instead of depending on unicode_names2 directly, leaving the crate as the sole
owner of the name database.
Assisted-by: Claude
* Add differential Unicode sweep and shared-crate snippet test
tests/differential.rs sweeps the full 0..0x110000 range and compares each str
classification predicate against a committed CPython 3.14 reference dataset
(tests/data/cpython3.14_predicates.txt, produced by generate_reference.py). Code
points that differ only because the Rust std / icu4x build ships a later Unicode
release than CPython 3.14's 16.0.0 are recorded in
tests/data/version_skew_cpython3.14.txt, regenerable via
RUSTPYTHON_UNICODE_REGEN_SKEW=1; the regen refuses to record any
cpython=true/crate=false divergence, so only newly-assigned code points are
allowed. Any other divergence fails. Both data files use a run-length
`predicate start:end,...` encoding.
extra_tests/snippets/stdlib_unicode_shared.py exercises the routed surface end to
end (str predicates, casefold, identifiers, unicodedata, normalize, \N{}, and re
character classes) and passes identically on CPython 3.14 and RustPython.
Assisted-by: Claude
* Match regex \d to Unicode decimal digits
is_uni_digit previously matched only ASCII 0-9, so re's \d in Unicode mode
missed decimal digits like ٥ and ५. SRE_UNI_IS_DIGIT matches Py_UNICODE_ISDECIMAL
(category Nd), so route it through classify::is_decimal. Unmasks test_bug_6561 in
test_re and extends the shared-crate snippet with the Nd/Nl/No cases.
Assisted-by: Claude
* Replace shallow Unicode wrappers with re-exports
Address review feedback on the extraction.
Functions that only forwarded to the shared crate become `use ... as`
re-exports rather than hand-written wrappers:
- literal: is_printable is dropped; escape.rs calls
rustpython_unicode::classify::is_repr_printable directly.
- unicode::identifier::is_continue re-exports is_xid_continue.
- unicode::data::lookup_character re-exports unicode_names2::character.
- Drop the unused repr(u8) on DecompositionType.
The SRE character-class and case predicates move back into
sre_engine::string (their pre-extraction home) instead of living in a
unicode::regex module that only sre_engine and the vm _sre binding used;
is_uni_digit/is_uni_alnum still delegate to rustpython_unicode::classify.
engine.rs and _sre consume them from sre_engine::string again.
The unicode crate's tests move from a single root tests module in lib.rs
into per-module test submodules (case, classify, data, identifier,
normalize).
Assisted-by: Claude
* no-std
* Address review feedback: test module, dead variant, WTF-8 normalization
- differential.rs: move the sweep tests into a `mod tests` block and drop
the file-level allow of clippy::tests_outside_test_module and
std_instead_of_alloc; the test uses alloc collections instead.
- data.rs: remove the never-constructed DecompositionType::Canonical variant
and its allow(unused); compatibility decomposition never produces it and
canonical decomposition is handled through icu4x.
- normalize.rs: is_normalized now takes &Wtf8 and checks each UTF-8 run,
skipping lone surrogates, matching normalize's run-wise behavior.
- unicodedata.rs: pass as_wtf8() to is_normalized.

Fix csv.writer QUOTE_NONE with quotechar=None (#8201)
* Prevent csv QUOTE_NONE writer panics without quotechar Handle csv.writer rows with QUOTE_NONE through a RustPython-owned unquoted writer path so quotechar=None no longer reaches the unfinished csv_core configuration branch. Escape delimiter, newline, quotechar, and escapechar bytes according to the active dialect, and preserve CPython's single-empty-field error behavior. Constraint: Match CPython csv.writer behavior without changing Lib/ copied stdlib files. Rejected: Relying on csv_core QuoteStyle::Never | it does not model CPython QUOTE_NONE escaping with quotechar=None. Confidence: high Scope-risk: narrow Directive: Keep QUOTE_NONE writer behavior separate unless csv_core gains matching CPython semantics. Tested: prek run --all-files; cargo test --workspace --exclude rustpython_wasm --exclude rustpython-venvlauncher; cargo build --release --features sqlite; pytest -v in extra_tests Assisted-by: Codex:gpt-5.5 * Keep csv parity tests aligned with QUOTE_NONE support Remove the stale RustPython expected-failure marker for the CPython escaped-field writer test that now passes, and cover CR/LF escaping in the snippet regression requested during review.

host_env: os.mkdir for Windows, Redox (#8128)
Python supports `mkdir` on Windows. I deferred to calling Rust's implementation for now. However, like `rename`, Python's implementation supports additional features that are currently unsupported on RustPython. I added a note for future reference. Redox supports `mkdirat` which significantly cleans up the implementation. |
