Gerlach * gh-91081: Add note on WeakKeyDictionary behavior when deleting a replaced entry (#91499) Co-authored-by: Pieter Eendebak Co-authored-by: Jelle Zijlstra * gh-85267: Improvements to inspect.signature __text_signature__ handling (#98796) This makes a couple related changes to inspect.signature's behaviour when parsing a signature from `__text_signature__`. First, `inspect.signature` is documented as only raising ValueError or TypeError. However, in some cases, we could raise RuntimeError. This PR changes that, thereby fixing #83685. (Note that the new ValueErrors in RewriteSymbolics are caught and then reraised with a message) Second, `inspect.signature` could randomly drop parameters that it didn't understand (corresponding to `return None` in the `p` function). This is the core issue in #85267. I think this is very surprising behaviour and it seems better to fail outright. Third, adding this new failure broke a couple tests. To fix them (and to e.g. allow `inspect.signature(select.epoll.register)` as in #85267), I add constant folding of a couple binary operations to RewriteSymbolics. (There's some discussion of making signature expression evaluation arbitrary powerful in #68155. I think that's out of scope. The additional constant folding here is pretty straightforward, useful, and not much of a slippery slope) Fourth, while #85267 is incorrect about the cause of the issue, it turns out if you had consecutive newlines in __text_signature__, you'd get `tokenize.TokenError`. Finally, the `if name is invalid:` code path was dead, since `parse_name` never returned `invalid`. * GH-100363: Speed up `asyncio.get_running_loop` (#100364) * GH-100133: fix `asyncio` subprocess losing `stderr` and `stdout` output (#100154) * gh-100374: Fixed a bug in socket.getfqdn() (gh-100375) * gh-100129: Add tests for pickling all builtin types and functions (GH-100142) * Remove unused variable from `dis._find_imports` (#100396) * gh-78878: Fix crash when creating an instance of `_ctypes.CField` (#14837) * GH-69564: Clarify use of octal format of mode argument in help(os.chmod) (#20621) Co-authored-by: Kumar Aditya <59607654+kumaraditya303@users.noreply.github.com> * GH-99554: Pack location tables more effectively (GH-99556) * Correct typo in typing.py (#100423) In the docstring of `ParamSpec`, the name of `P = ParamSpec('P')` was mistakenly written as `'T'`. * gh-99761: Add `_PyLong_IsPositiveSingleDigit` function to check for single digit integers (#100064) * GH-99770: Make the correct call specialization fail kind show up in the stats (GH-99771) * gh-78997: fix bad rebase of moved test file (#100424) * gh-100344: Add C implementation for `asyncio.current_task` (#100345) Co-authored-by: pranavtbhat * GH-99554: Trim trailing whitespace (GH-100435) Automerge-Triggered-By: GH:brandtbucher * gh-85432: Harmonise parameter names between C and pure-Python implementations of `datetime.time.strftime`, `datetime.datetime.fromtimestamp` (#99993) * gh-57762: fix misleading tkinter.Tk docstring (#98837) Mentioned as a desired change by terryjreedy on the corresponding issue, since Tk is not a subclass of Toplevel. * gh-48496: Added example and link to faq for UnboundLocalError in reference (#93068) * Fix typo in 3.12 What's New (#100449) * gh-76963: PEP3118 itemsize of an empty ctypes array should not be 0 (GH-5576) The itemsize returned in a memoryview of a ctypes array is now computed from the item type, instead of dividing the total size by the length and assuming that the length is not zero. * GH-100459: fix copy-paste errors in specialization stats (GH-100460) * gh-99110: Initialize `frame->previous` in init_frame to fix segmentation fault when accessing `frame.f_back` (#100182) * gh-98712: Clarify "readonly bytes-like object" semantics in C arg-parsing docs (#98710) * gh-92216: improve performance of `hasattr` for type objects (GH-99979) * gh-100288: Specialise LOAD_ATTR_METHOD for managed dictionaries (GH-100289) * Revert "gh-100288: Specialise LOAD_ATTR_METHOD for managed dictionaries (GH-100289)" (#100468) This reverts commit c3c7848a48b74a321632202e4bdcf2f465fb1cc6. * gh-94155: Reduce hash collisions for code objects (#100183) * Uses a better hashing algorithm to get better dispersion and remove commutativity. * Incorporates `co_firstlineno`, `Py_SIZE(co)`, and bytecode instructions. * This is now the entire set of criteria used in `code_richcompare`, except for `_PyCode_ConstantKey` (which would incorporate the types of `co_consts` rather than just their values). * gh-83076: 3.8x speed improvement in (Async)Mock instantiation (#100252) * gh-99482: remove `jython` compatibility parts from stdlib and tests (#99484) * bpo-40447: accept all path-like objects in compileall.compile_file (#19883) Signed-off-by: Filipe Laíns Signed-off-by: Filipe Laíns Co-authored-by: Irit Katriel <1055913+iritkatriel@users.noreply.github.com> Co-authored-by: Shantanu <12621235+hauntsaninja@users.noreply.github.com> * GH-100425: Improve accuracy of builtin sum() for float inputs (GH-100426) * gh-68320, gh-88302 - Allow for private `pathlib.Path` subclassing (GH-31691) Users may wish to define subclasses of `pathlib.Path` to add or modify existing methods.
