* [3.12] gh-105375: Improve PyErr_WarnExplicit() error handling (GH-105610) ↵Miss Islington (bot)2023-06-111-12/+16
| | | | | | | | | (#105659) Bail on first error to prevent exceptions from possibly being overwritten. (cherry picked from commit 567d6ae8e77579173510fc948ac06b2ababf3d40) Co-authored-by: Erlend E. Aasland <erlend.aasland@protonmail.com>
* gh-104341: Adjust tstate_must_exit() to Respect Interpreter Finalization ↵Eric Snow2023-05-151-1/+1
| | | | | (gh-104437) With the move to a per-interpreter GIL, this check slipped through the cracks.
* gh-99113: Add Py_MOD_PER_INTERPRETER_GIL_SUPPORTED (gh-104205)Eric Snow2023-05-051-0/+1
| | | Here we are doing no more than adding the value for Py_mod_multiple_interpreters and using it for stdlib modules. We will start checking for it in gh-104206 (once PyInterpreterState.ceval.own_gil is added in gh-104204).
* gh-101758: Clean Up Uses of Import State (gh-101919)Eric Snow2023-02-151-9/+2
| | | | | | | | | | | | | | | This change is almost entirely moving code around and hiding import state behind internal API. We introduce no changes to behavior, nor to non-internal API. (Since there was already going to be a lot of churn, I took this as an opportunity to re-organize import.c into topically-grouped sections of code.) The motivation is to simplify a number of upcoming changes. Specific changes: * move existing import-related code to import.c, wherever possible * add internal API for interacting with import state (both global and per-interpreter) * use only API outside of import.c (to limit churn there when changing the location, etc.) * consolidate the import-related state of PyInterpreterState into a single struct field (this changes layout slightly) * add macros for import state in import.c (to simplify changing the location) * group code in import.c into sections *remove _PyState_AddModule() https://github.com/python/cpython/issues/101758

* gh-39615: Add warnings.warn() skip_file_prefixes support (#100840)Gregory P. Smith2023-01-281-24/+103
| | | | | `warnings.warn()` gains the ability to skip stack frames based on code filename prefix rather than only a numeric `stacklevel=` via a new `skip_file_prefixes=` keyword argument.
* gh-99537: Use Py_SETREF() function in C code (#99657)Victor Stinner2022-11-221-4/+2
| | | | | | | | | | | | | | | Fix potential race condition in code patterns: * Replace "Py_DECREF(var); var = new;" with "Py_SETREF(var, new);" * Replace "Py_XDECREF(var); var = new;" with "Py_XSETREF(var, new);" * Replace "Py_CLEAR(var); var = new;" with "Py_XSETREF(var, new);" Other changes: * Replace "old = var; var = new; Py_DECREF(var)" with "Py_SETREF(var, new);" * Replace "old = var; var = new; Py_XDECREF(var)" with "Py_XSETREF(var, new);" * And remove the "old" variable.
* gh-99300: Use Py_NewRef() in Python/ directory (#99302)Victor Stinner2022-11-101-8/+4
| | | | Replace Py_INCREF() and Py_XINCREF() with Py_NewRef() and Py_XNewRef() in C files of the Python/ directory.

* gh-86298: Ensure that __loader__ and __spec__.loader agree in ↵Barry Warsaw2022-10-071-3/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | warnings.warn_explicit() (GH-97803) In `_warnings.c`, in the C equivalent of `warnings.warn_explicit()`, if the module globals are given (and not None), the warning will attempt to get the source line for the issued warning. To do this, it needs the module's loader. Previously, it would only look up `__loader__` in the module globals. In https://github.com/python/cpython/issues/86298 we want to defer to the `__spec__.loader` if available. The first step on this journey is to check that `loader == __spec__.loader` and issue another warning if it is not. This commit does that. Since this is a PoC, only manual testing for now. ```python # /tmp/foo.py import warnings import bar warnings.warn_explicit( 'warning!', RuntimeWarning, 'bar.py', 2, module='bar knee', module_globals=bar.__dict__, ) ``` ```python # /tmp/bar.py import sys import os import pathlib # __loader__ = pathlib.Path() ``` Then running this: `./python.exe -Wdefault /tmp/foo.py` Produces: ``` bar.py:2: RuntimeWarning: warning! import os ``` Uncomment the `__loader__ = ` line in `bar.py` and try it again: ``` sys:1: ImportWarning: Module bar; __loader__ != __spec__.loader (<_frozen_importlib_external.SourceFileLoader object at 0x109f7dfa0> != PosixPath('.')) bar.py:2: RuntimeWarning: warning! import os ``` Automerge-Triggered-By: GH:warsaw

* gh-93937, C API: Move PyFrame_GetBack() to Python.h (#93938)Victor Stinner2022-06-191-1/+0
| | | | | | | | | | | | | | | | Move the follow functions and type from frameobject.h to pyframe.h, so the standard <Python.h> provide frame getter functions: * PyFrame_Check() * PyFrame_GetBack() * PyFrame_GetBuiltins() * PyFrame_GetGenerator() * PyFrame_GetGlobals() * PyFrame_GetLasti() * PyFrame_GetLocals() * PyFrame_Type Remove #include "frameobject.h" from many C files.

* bpo-46541: Discover the global strings. (gh-31346)Eric Snow2022-02-151-2/+2
| | | | | | | Instead of manually enumerating the global strings in generate_global_objects.py, we extrapolate the list from usage of _Py_ID() and _Py_STR() in the source files. This is partly inspired by gh-31261. https://bugs.python.org/issue46541
* bpo-46541: Replace core use of _Py_IDENTIFIER() with statically initialized ↵Eric Snow2022-02-081-113/+150
| | | | | | | | | | | | | | | | | | | | | | | | | | | | global objects. (gh-30928) We're no longer using _Py_IDENTIFIER() (or _Py_static_string()) in any core CPython code. It is still used in a number of non-builtin stdlib modules. The replacement is: PyUnicodeObject (not pointer) fields under _PyRuntimeState, statically initialized as part of _PyRuntime. A new _Py_GET_GLOBAL_IDENTIFIER() macro facilitates lookup of the fields (along with _Py_GET_GLOBAL_STRING() for non-identifier strings). https://bugs.python.org/issue46541#msg411799 explains the rationale for this change. The core of the change is in: * (new) Include/internal/pycore_global_strings.h - the declarations for the global strings, along with the macros * Include/internal/pycore_runtime_init.h - added the static initializers for the global strings * Include/internal/pycore_global_objects.h - where the struct in pycore_global_strings.h is hooked into _PyRuntimeState * Tools/scripts/generate_global_objects.py - added generation of the global string declarations and static initializers I've also added a --check flag to generate_global_objects.py (along with make check-global-objects) to check for unused global strings. That check is added to the PR CI config. The remainder of this change updates the core code to use _Py_GET_GLOBAL_IDENTIFIER() instead of _Py_IDENTIFIER() and the related _Py*Id functions (likewise for _Py_GET_GLOBAL_STRING() instead of _Py_static_string()). This includes adding a few functions where there wasn't already an alternative to _Py*Id(), replacing the _Py_Identifier * parameter with PyObject *. The following are not changed (yet): * stop using _Py_IDENTIFIER() in the stdlib modules * (maybe) get rid of _Py_IDENTIFIER(), etc. entirely -- this may not be doable as at least one package on PyPI using this (private) API * (maybe) intern the strings during runtime init https://bugs.python.org/issue46541
* bpo-44590: Lazily allocate frame objects (GH-27077)Mark Shannon2021-07-261-4/+2
| | | | | | | | | | | | | | * Convert "specials" array to InterpreterFrame struct, adding f_lasti, f_state and other non-debug FrameObject fields to it. * Refactor, calls pushing the call to the interpreter upward toward _PyEval_Vector. * Compute f_back when on thread stack, only filling in value when frame object outlives stack invocation. * Move ownership of InterpreterFrame in generator from frame object to generator object. * Do not create frame objects for Python calls. * Do not create frame objects for generators.

* bpo-44032: Move data stack to thread from FrameObject. (GH-26076)Mark Shannon2021-05-211-1/+2
| | | | | | | | | | | | | | | | * Remove 'zombie' frames. We won't need them once we are allocating fixed-size frames. * Add co_nlocalplus field to code object to avoid recomputing size of locals + frees + cells. * Move locals, cells and freevars out of frame object into separate memory buffer. * Use per-threadstate allocated memory chunks for local variables. * Move globals and builtins from frame object to per-thread stack. * Move (slow) locals frame object to per-thread stack. * Move internal frame functions to internal header.
* bpo-43268: Pass interp rather than tstate to internal functions (GH-24580)Victor Stinner2021-02-191-2/+2
| | | | | | | | | | | | | | | Pass the current interpreter (interp) rather than the current Python thread state (tstate) to internal functions which only use the interpreter. Modified functions: * _PyXXX_Fini() and _PyXXX_ClearFreeList() functions * _PyEval_SignalAsyncExc(), make_pending_calls() * _PySys_GetObject(), sys_set_object(), sys_set_object_id(), sys_set_object_str() * should_audit(), set_flags_from_config(), make_flags() * _PyAtExit_Call() * init_stdio_encoding() * etc.

| | | | | | | | | | * Call _PyTime_Init() and _PyWarnings_InitState() earlier during the Python initialization. * Inline _PyImportHooks_Init() into _PySys_InitCore(). * The _warnings initialization function no longer call _PyWarnings_InitState() to prevent resetting filters_version to 0. * _PyWarnings_InitState() now returns an int and no longer clear the state in case of error (it's done anyway at Python exit). * Rework init_importlib(), fix refleaks on errors.
* bpo-1635741: Fix ref leak in _PyWarnings_Init() error path (GH-23151)Victor Stinner2020-11-041-8/+3

| | | | | | | | The _PyErr_WarnUnawaitedCoroutine() fallback now also sets the coroutine object as the source of the warning, as done by the Python implementation warnings._warn_unawaited_coroutine(). Moreover, don't truncate the coroutine name: Python supports arbitrary string length to format the message.
