| | | | | | | | gh-129917: Update installers to use SQLite 3.49.1 (GH-131025) (cherry picked from commit 45a3ab5a81769eadd94da3e26eb9bb2f3ae80fb1) Co-authored-by: Erlend E. Aasland <erlend@python.org> Co-authored-by: Ned Deily <nad@python.org>
* gh-131423: Update to OpenSSL 3.0.16. (GH-131839)Steve Dower2025-03-285-35/+5
| | | | | The bin tag is 3.0.16.1 because we rebuilt without uplink support to fix gh-131804. This PR also prevents making calls that are now unsafe without uplink, and updates the tests to property interpret these failures as unsupported.

* gh-118335: Configure Tier 2 interpreter at build time (#118339)Guido van Rossum2024-05-013-2/+16
| | | | | | | | | | | | | | | | | | | | | | The code for Tier 2 is now only compiled when configured with `--enable-experimental-jit[=yes|interpreter]`. We drop support for `PYTHON_UOPS` and -`Xuops`, but you can disable the interpreter or JIT at runtime by setting `PYTHON_JIT=0`. You can also build it without enabling it by default using `--enable-experimental-jit=yes-off`; enable with `PYTHON_JIT=1`. On Windows, the `build.bat` script supports `--experimental-jit`, `--experimental-jit-off`, `--experimental-interpreter`. In the C code, `_Py_JIT` is defined as before when the JIT is enabled; the new variable `_Py_TIER2` is defined when the JIT *or* the interpreter is enabled. It is actually a bitmask: 1: JIT; 2: default-off; 4: interpreter.

* 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 Snow2024-04-024-0/+8
| | | 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-76785: Drop PyInterpreterID_Type (gh-117101)Eric Snow2024-03-214-16/+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.
* gh-115754: Add Py_GetConstant() function (#116883)Victor Stinner2024-03-212-0/+2
| | | | | | | | | | | | Add Py_GetConstant() and Py_GetConstantBorrowed() functions. In the limited C API version 3.13, getting Py_None, Py_False, Py_True, Py_Ellipsis and Py_NotImplemented singletons is now implemented as function calls at the stable ABI level to hide implementation details. Getting these constants still return borrowed references. Add _testlimitedcapi/object.c and test_capi/test_object.py to test Py_GetConstant() and Py_GetConstantBorrowed() functions.
* gh-116417: Move limited C API complex.c tests to _testlimitedcapi (#117014)Victor Stinner2024-03-192-0/+2

* gh-108716: Cleanup remaining deepfreeze infrastructure (#116919)Guido van Rossum2024-03-182-24/+0
| | | | | 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.
* gh-115119: Switch Windows build to mpdecimal external (GH-115182)Zachary Ware2024-03-184-63/+75
