* gh-108082: Use PyErr_FormatUnraisable() (GH-111580)Serhiy Storchaka2023-11-021-17/+3
| | | | | | Replace most of calls of _PyErr_WriteUnraisableMsg() and some calls of PyErr_WriteUnraisable(NULL) with PyErr_FormatUnraisable(). Co-authored-by: Victor Stinner <vstinner@python.org>
* GH-107265: Add missing deoptimizations for ENTER_EXECUTOR's original opcode ↵Tian Gao2023-09-221-1/+1

* gh-107265: Remove all ENTER_EXECUTOR when execute _Py_Instrument (gh-108539)Dong-hee Na2023-09-071-0/+17
|
* gh-108751: Add copy.replace() function (GH-108752)Serhiy Storchaka2023-09-061-0/+1
| | | | | | | | | It creates a modified copy of an object by calling the object's __replace__() method. It is a generalization of dataclasses.replace(), named tuple's _replace() method and replace() methods in various classes, and supports all these stdlib classes.
* gh-105481: remove regen-opcode. Generated _PyOpcode_Caches in regen-cases. ↵Irit Katriel2023-08-231-2/+1

* gh-106581: Project through calls (#108067)Guido van Rossum2023-08-171-0/+3
| | | | This finishes the work begun in gh-107760. When, while projecting a superblock, we encounter a call to a short, simple function, the superblock will now enter the function using `_PUSH_FRAME`, continue through it, and leave it using `_POP_FRAME`, and then continue through the original code. Multiple frame pushes and pops are even possible. It is also possible to stop appending to the superblock in the middle of a called function, when running out of space or encountering an unsupported bytecode.
* gh-105481: generate op IDs from bytecode.c instead of hard coding them in ↵Irit Katriel2023-08-161-1/+2
| | | | opcode.py (#107971)

| | | | Since Python 3.12, PyUnicode_READY() does nothing and always returns 0.

| | | | | | | * 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-99845: Clean up _PyObject_VAR_SIZE() usage (#99847)Victor Stinner2022-11-291-6/+4
| | | | | | * code_sizeof() now uses an unsigned type (size_t) to compute the result. * Fix _PyObject_ComputedDictPointer(): cast _PyObject_VAR_SIZE() to Py_ssize_t, rather than long: it's a different type on 64-bit Windows. * Clarify that _PyObject_VAR_SIZE() uses an unsigned type (size_t).
