* Emit CACHE code units in bytecode to match CPython 3.14
- Add cache_entries() method to Instruction enum
- Emit CACHE code units after opcodes in finalize_code
- Handle NO_LOCATION (line=-1) in linetable for CACHE entries
- Account for CACHE entries in exception table generation
- Skip CACHE entries in VM execution loop (with jump detection)
- Handle CACHE in InstrumentedLine/InstrumentedInstruction/InstrumentedForIter/InstrumentedNotTaken
- Skip CACHE in monitoring instrumentation phases
- Update co_branches() for cache-adjusted offsets
- Restore _cache_format in Lib/opcode.py
- Remove expectedFailure from test_c_call, test_start_offset
* Use relative jump offsets and fix bytecode layout
- Convert jump arguments from absolute to relative offsets
in frame.rs, monitoring.rs, and stack_analysis
- Add jump_relative_forward/backward helpers to ExecutingFrame
- Resolve pseudo jump instructions before offset fixpoint loop
- Emit NOP for break, continue, pass to match line-tracing
- Fix async for: emit EndAsyncFor with correct target, add NotTaken
- Fix comprehension if-cleanup to use separate block
- Fix super() source range for multi-line calls
- Fix NOP removal to preserve line-marker NOPs
- Fix InstrumentedLine cache skipping after re-dispatch
- Match InstrumentedResume/YieldValue in yield_from_target
- Remove CALL_FUNCTION_EX cache entry from opcode.py
- Remove resolved expectedFailure markers
* Align CPython 3.14 LOAD_GLOBAL null-bit and RERAISE semantics
* Remove redundant CPython-referencing comments
Clean up comments that unnecessarily mention CPython per project
convention. Replace with concise descriptions of the behavior itself.
- Add TraceEvent::Exception and Opcode variants with profile filtering
- Extract dispatch_traced_frame helper for Call/Return trace events
- Fire exception trace on new raises, SEND StopIteration, FOR_ITER StopIteration
- Fire opcode trace events gated by f_trace_opcodes
- Move prev_line to FrameState for persistence across generator suspend/resume
- Reset prev_line in gen_throw for correct LINE monitoring after yield
- Add per-code event mask (events_for_code) to prevent unrelated code instrumentation
- Remove expectedFailure markers from test_bdb (5) and test_sys_setprofile (14)
Add non-ASCII string check to _hashlib.compare_digest, matching the
behavior of _operator._compare_digest. When both arguments are strings,
non-ASCII characters now correctly raise TypeError.
Also replace the non-constant-time == comparison with constant_time_eq
for proper timing-attack resistance, and return PyResult<bool> instead
of PyResult<PyObjectRef>.
Add #[pygetset] getter/setter for Cursor.row_factory so that Python-level
attribute access reads/writes the Rust struct field instead of the
instance dict.
Fix Connection.cursor() to only propagate the connection's row_factory
to the cursor when the connection's row_factory is not None, matching
CPython behavior. Previously it unconditionally overwrote the cursor's
row_factory, discarding any factory set by a cursor subclass __init__.
When a custom `closed` property on the underlying buffer calls
`detach()` during the `file_closed()` check in `close()`, the
wrapper's internal buffer becomes None. Subsequent flush/close
operations then fail with AttributeError on NoneType.
Add a guard after the `file_closed()` check to detect if the buffer
was detached reentrantly, and return early in that case (detach has
already flushed the stream).
This mirrors the fix applied in CPython
(https://github.com/python/cpython/issues/142594\).
- Return trace function's return value from trace_event()
to support per-frame f_trace assignment
- Match CPython's trace_trampoline: set f_trace from call
event return value, clear on error
- Fire return event only when frame is traced or profiled
- Remove expectedFailure from passing bdb/settrace tests
- Implement set_f_lineno with stack analysis and deferred unwinding
- Add Frame::set_lasti() for trace callback line jumps
- Implement co_branches() on code objects
- Clear _cache_format in opcode.py (no inline caches)
- Fix getattro slot inheritance: preserve native slot from inherit_slots
- Fix BRANCH_RIGHT src_offset in InstrumentedPopJumpIf*
- Move lasti increment before line event for correct f_lineno
- Skip RESUME instruction from generating line events
- Defer stack pops via pending_stack_pops/pending_unwind_from_stack
to avoid deadlock with state mutex
- Fix ForIter exhaust target in mark_stacks to skip END_FOR
- Prevent exception handler paths from overwriting normal-flow stacks
- Replace #[cfg(feature = "threading")] duplication with PyAtomic<T>
from rustpython_common::atomic (Radium-based unified API)
- Remove expectedFailure from 31 now-passing jump tests
* Clear frame locals and stack on generator close
Add Frame::clear_locals_and_stack() to release references held by
closed generators/coroutines, matching _PyFrame_ClearLocals behavior.
Call it from Coro::close() after marking the coroutine as closed.
Update test_generators.py expectedFailure markers accordingly.
* Add dir_fd support for rmdir, remove/unlink, scandir
- rmdir: use unlinkat(fd, path, AT_REMOVEDIR) when dir_fd given
- remove/unlink: use unlinkat(fd, path, 0) when dir_fd given
- scandir: accept fd via fdopendir, add ScandirIteratorFd
- listdir: rewrite fd path to use raw readdir instead of nix::dir::Dir
- DirEntry: add d_type and dir_fd fields for fd-based scandir
- Update supports_fd/supports_dir_fd entries accordingly
* cells_free
* Implement Windows SemLock in _multiprocessing module
Add SemLock class using Windows semaphore APIs (CreateSemaphoreW,
WaitForSingleObjectEx, ReleaseSemaphore) so test_multiprocessing
suites are no longer skipped with "lacks a functioning sem_open".
Also add sem_unlink as no-op and flags dict for Windows.
* Fix _multiprocessing recv to return bytes and improve SemLock reliability
- recv() now returns bytes instead of int (matching CPython)
- Remove spurious GetLastError() check after CreateSemaphoreW
- Add signal checking during blocking SemLock acquire
* Include winerror in OSError.__reduce__ on Windows
* Remove expectedFailure for tests now passing with Windows SemLock
* Fix OSError.__reduce__ to preserve winerror when filename is None
When filename is None, __reduce__ was reconstructing a 2-element
(errno, msg) tuple, dropping the winerror at position 3 in the
original args. Use the original args tuple instead, matching CPython.
* Validate maxvalue > 0 in SemLock and document winerror __reduce__ divergence
* Reject embedded null characters in mmap tagname and _winapi file mapping names
