* gh-122292: Split up ``Lib/test/test_ast.py`` into a couple of files (#122293)Kirill Podoprigora2024-07-291-0/+1
|
* gh-100240: Use a consistent implementation for freelists (#121934)Sam Gross2024-07-221-0/+1
| | | | | | | | This combines and updates our freelist handling to use a consistent implementation. Objects in the freelist are linked together using the first word of memory block. If configured with freelists disabled, these operations are essentially no-ops.
* gh-120522: Apply App Store compliance patch during installation (#121947)Russell Keith-Magee2024-07-211-1/+22
| | | Adds a --with-app-store-compliance configuration option that patches out code known to be an issue with App Store review processes. This option is applied automatically on iOS, and optionally on macOS.
* gh-120522: Revert "Add a `--with-app-store-compliance` configure option to ↵Ned Deily2024-07-161-16/+1
| | | | | | patch out problematic code" (gh-120984) (#121844) This reverts commit 48cd104b0cf05dad8958efa9cb9666c029ef9201 prior to the release of 3.13.0b4 to allow for additional review time.
* gh-121103: Put free-threaded libraries in `lib/python3.14t` (#121293)Sam Gross2024-07-111-1/+2
| | | | | On POSIX systems, excluding macOS framework installs, the lib directory for the free-threaded build now includes a "t" suffix to avoid conflicts with a co-located default build installation.
* gh-121467: Fix makefile to include mimalloc headers (#121469)Marc Mueller2024-07-081-2/+2

* gh-112136: Restore removed _PyArg_Parser (#121262)Victor Stinner2024-07-031-0/+1
| | | | | | | Restore the private _PyArg_Parser structure and the private _PyArg_ParseTupleAndKeywordsFast() function, previously removed in Python 3.13 alpha 1. Recreate Include/cpython/modsupport.h header file.
* gh-61103: Support double complex (_Complex) type in ctypes (#120894)Sergey B Kirpichev2024-07-011-1/+1

* gh-120686: remove unused internal c api functions (#120687)Irit Katriel2024-06-271-1/+0

* gh-117139: Convert the evaluation stack to stack refs (#118450)Ken Jin2024-06-261-0/+1
| | | | | | | | | | | | | | | | | This PR sets up tagged pointers for CPython. The general idea is to create a separate struct _PyStackRef for everything on the evaluation stack to store the bits. This forces the C compiler to warn us if we try to cast things or pull things out of the struct directly. Only for free threading: We tag the low bit if something is deferred - that means we skip incref and decref operations on it. This behavior may change in the future if Mark's plans to defer all objects in the interpreter loop pans out. This implies a strict stack reference discipline is required. ALL incref and decref operations on stackrefs must use the stackref variants. It is unsafe to untag something then do normal incref/decref ops on it. The new incref and decref variants are called dup and close. They mimic a "handle" API operating on these stackrefs. Please read Include/internal/pycore_stackref.h for more information! --------- Co-authored-by: Mark Shannon <9448417+markshannon@users.noreply.github.com>

* gh-119344: Make critical section API public (#119353)Sam Gross2024-06-211-0/+2
| | | | | | | | | | This makes the following macros public as part of the non-limited C-API for locking a single object or two objects at once. * `Py_BEGIN_CRITICAL_SECTION(op)` / `Py_END_CRITICAL_SECTION()` * `Py_BEGIN_CRITICAL_SECTION2(a, b)` / `Py_END_CRITICAL_SECTION2()` The supporting functions and structs used by the macros are also exposed for cases where C macros are not available.

* gh-119729: Use 't' in pkg-config file name for free-threaded build (#119738)Sam Gross2024-05-301-7/+7
| | | | | For example, the free-threaded build now generates `lib/pkgconfig/python-3.13t.pc` and the debug build generates `lib/pkgconfig/python-3.13d.pc`.
* gh-97588: Align ctypes struct layout to GCC/MSVC (GH-97702)Matthias Görgens2024-05-291-0/+1

* gh-116818: Make `sys.settrace`, `sys.setprofile`, and monitoring thread-safe ↵Dino Viehland2024-04-191-0/+1
| | | | | | | (#116775) Makes sys.settrace, sys.setprofile, and monitoring generally thread-safe. Mostly uses a stop-the-world approach and synchronization around the code object's _co_instrumentation_version. There may be a little bit of extra synchronization around the monitoring data that's required to be TSAN clean.

* gh-116968: Reimplement Tier 2 counters (#117144)Guido van Rossum2024-04-041-0/+1
| | | | | | | | | | | | Introduce a unified 16-bit backoff counter type (``_Py_BackoffCounter``), shared between the Tier 1 adaptive specializer and the Tier 2 optimizer. The API used for adaptive specialization counters is changed but the behavior is (supposed to be) identical. The behavior of the Tier 2 counters is changed: - There are no longer dynamic thresholds (we never varied these). - All counters now use the same exponential backoff. - The counter for ``JUMP_BACKWARD`` starts counting down from 16. - The ``temperature`` in side exits starts counting down from 64.
* gh-76785: Add PyInterpreterConfig Helpers (gh-117170)Eric Snow2024-04-021-0/+5
| | | These helpers make it easier to customize and inspect the config used to initialize interpreters. This is especially valuable in our tests. I found inspiration from the PyConfig API for the PyInterpreterConfig dict conversion stuff. As part of this PR I've also added a bunch of tests.
* gh-117323: Make `cell` thread-safe in free-threaded builds (#117330)Sam Gross2024-03-291-0/+1
| | | Use critical sections to lock around accesses to cell contents. The critical sections are no-ops in the default (with GIL) build.

* gh-76785: Drop PyInterpreterID_Type (gh-117101)Eric Snow2024-03-211-3/+0
| | | I added it quite a while ago as a strategy for managing interpreter lifetimes relative to the PEP 554 (now 734) implementation. Relatively recently I refactored that implementation to no longer rely on InterpreterID objects. Thus now I'm removing it.

| | | | | | | * Split long.c tests of _testcapi into two parts: limited C API tests in _testlimitedcapi and non-limited C API tests in _testcapi. * Move testcapi_long.h from Modules/_testcapi/ to Modules/_testlimitedcapi/. * Add MODULE__TESTLIMITEDCAPI_DEPS to Makefile.pre.in.

| | | | | Keep Tools/build/deepfreeze.py around (we may repurpose it for deepfreezing non-code objects), and keep basic "clean" targets that remove the output of former deep-freeze activities, to keep the build directories of current devs clean.

| | | | | | If awailable, enable -fstrict-overflow for libmpdec. Also shut off false positive warnings (-Warray-bounds). The later was backported from mpdecimal-4.0.0.
* gh-71052: Fix several Android build issues (#115955)Malcolm Smith2024-02-291-4/+2
| | | | | | | | | | | | | | | | | | | This change is part of the work on PEP-738: Adding Android as a supported platform. * Remove the "1.0" suffix from libpython's filename on Android, which would prevent Gradle from packaging it into an app. * Simplify the build command in the Makefile so that libpython always gets given an SONAME with the `-Wl-h` argument, even if the SONAME is identical to the actual filename. * Disable a number of functions on Android which can be compiled and linked against, but always fail at runtime. As a result, the native _multiprocessing module is no longer built for Android. * gh-115390 (bee7bb331) added some pre-determined results to the configure script for things that can't be autodetected when cross-compiling; this change adds Android to these where appropriate. * Add a couple more pre-determined results for Android, and making them cover iOS as well. This means the --enable-ipv6 configure option will no longer be required on either platform.
* GH-115816: Make tier2 optimizer symbols testable, and add a few tests. ↵Mark Shannon2024-02-271-0/+1
