* [3.13] gh-118851: Default ctx arguments to AST constructors to Load() ↵Miss Islington (bot)2024-05-091-0/+7
| | | | | | | | (GH-118854) (#118871) (cherry picked from commit 68fbc00dc870f6a8dcbecd2ec19298e21015867f) Co-authored-by: Jelle Zijlstra <jelle.zijlstra@gmail.com> Co-authored-by: Alex Waygood <Alex.Waygood@Gmail.com>

* gh-117953: Always Run Extension Init Func in Main Interpreter First (gh-118157)Eric Snow2024-05-071-55/+197
| | | This change makes sure all extension/builtin modules have their init function run first by the main interpreter before proceeding with import in the original interpreter (main or otherwise). This means when the import of a single-phase init module fails in an isolated subinterpreter, it won't tie any global state/callbacks to the subinterpreter.
* gh-117953: Imply Single-phase Init if the Init Function Fails (gh-118684)Eric Snow2024-05-071-0/+7
| | | This ensures the kind is always either _Py_ext_module_kind_SINGLEPHASE or _Py_ext_module_kind_MULTIPHASE.
* gh-116322: Enable the GIL while loading C extension modules (#118560)Brett Simmers2024-05-074-26/+269
| | | | | | | | | | Add the ability to enable/disable the GIL at runtime, and use that in the C module loading code. We can't know before running a module init function if it supports free-threading, so the GIL is temporarily enabled before doing so. If the module declares support for running without the GIL, the GIL is later disabled. Otherwise, the GIL is permanently enabled, and will never be disabled again for the life of the current interpreter.

* gh-117486: Improve behavior for user-defined AST subclasses (#118212)Jelle Zijlstra2024-05-061-14/+17
| | | | | | | | Now, such classes will no longer require changes in Python 3.13 in the normal case. The test suite for robotframework passes with no DeprecationWarnings under this PR. I also added a new DeprecationWarning for the case where `_field_types` exists but is incomplete, since that seems likely to indicate a user mistake.

* gh-117953: Track Extra Details in Global Extensions Cache (gh-118532)Eric Snow2024-05-042-137/+567
| | | | | | | | | | | | We have only been tracking each module's PyModuleDef. However, there are some problems with that. For example, in some cases we load single-phase init extension modules from def->m_base.m_init or def->m_base.m_copy, but if multiple modules share a def then we can end up with unexpected behavior. With this change, we track the following: * PyModuleDef (same as before) * for some modules, its init function or a copy of its __dict__, but specific to that module * whether it is a builtin/core module or a "dynamic" extension * the interpreter (ID) that owns the cached __dict__ (only if cached) This also makes it easier to remember the module's kind (e.g. single-phase init) and if loading it previously failed, which I'm doing separately.

* gh-110850: Use _PyDeadline_Get() in EnterNonRecursiveMutex() (#118556)Victor Stinner2024-05-041-6/+7
| | | | | | | | Use _PyDeadline_Init() and _PyDeadline_Get() in EnterNonRecursiveMutex() of thread_nt.h. _PyDeadline_Get() uses the monotonic clock which is now the same as the perf counter clock on all platforms. So this change does not cause any behavior change. It just reuses existing helper functions.

* gh-116322: Add Py_mod_gil module slot (#116882)Brett Simmers2024-05-037-0/+11
| | | | | | | | | | | | | | This PR adds the ability to enable the GIL if it was disabled at interpreter startup, and modifies the multi-phase module initialization path to enable the GIL when loading a module, unless that module's spec includes a slot indicating it can run safely without the GIL. PEP 703 called the constant for the slot `Py_mod_gil_not_used`; I went with `Py_MOD_GIL_NOT_USED` for consistency with gh-104148. A warning will be issued up to once per interpreter for the first GIL-using module that is loaded. If `-v` is given, a shorter message will be printed to stderr every time a GIL-using module is loaded (including the first one that issues a warning).
* gh-117514: Add `sys._is_gil_enabled()` function (#118514)Sam Gross2024-05-032-1/+49
| | | | | The function returns `True` or `False` depending on whether the GIL is currently enabled. In the default build, it always returns `True` because the GIL is always enabled.
* gh-118527: Use `_Py_ID(__main__)` for main module name (#118528)Sam Gross2024-05-031-1/+1
| | | | | Most module names are interned and immortalized, but the main module was not. This partially addresses a scaling bottleneck in the free-threaded when creating closure concurrently in the main module.

* gh-116738: Make `_codecs` module thread-safe (#117530)Brett Simmers2024-05-022-73/+81
| | | | | | | | | | | | | | | The module itself is a thin wrapper around calls to functions in `Python/codecs.c`, so that's where the meaningful changes happened: - Move codecs-related state that lives on `PyInterpreterState` to a struct declared in `pycore_codecs.h`. - In free-threaded builds, add a mutex to `codecs_state` to synchronize operations on `search_path`. Because `search_path_mutex` is used as a normal mutex and not a critical section, we must be extremely careful with operations called while holding it. - The codec registry is explicitly initialized as part of `_PyUnicode_InitEncodings` to simplify thread-safety.
