* GH-118093: Make `CALL_ALLOC_AND_ENTER_INIT` suitable for tier 2. (GH-123140)Mark Shannon2024-08-201-0/+4
| | | | | * Convert CALL_ALLOC_AND_ENTER_INIT to micro-ops such that tier 2 supports it * Allow inexact arguments for CALL_ALLOC_AND_ENTER_INIT.
* gh-99108: Add HACL* Blake2 implementation to hashlib (GH-119316)Jonathan Protzenko2024-08-131-0/+3
| | | | | | | This replaces the existing hashlib Blake2 module with a single implementation that uses HACL\*'s Blake2b/Blake2s implementations. We added support for all the modes exposed by the Python API, including tree hashing, leaf nodes, and so on. We ported and merged all of these changes upstream in HACL\*, added test vectors based on Python's existing implementation, and exposed everything needed for hashlib. This was joint work done with @R1kM. See the PR for much discussion and benchmarking details. TL;DR: On many systems, 8-50% faster (!) than `libb2`, on some systems it appeared 10-20% slower than `libb2`.

| | | | | | | | | | | | | | | | | | Example: ```pycon >>> import ctypes >>> ctypes.__STDC_IEC_559_COMPLEX__ 1 >>> libm = ctypes.CDLL('libm.so.6') >>> libm.clog.argtypes = [ctypes.c_double_complex] >>> libm.clog.restype = ctypes.c_double_complex >>> libm.clog(1+1j) (0.34657359027997264+0.7853981633974483j) ``` Co-authored-by: Nice Zombies <nineteendo19d0@gmail.com> Co-authored-by: Bénédikt Tran <10796600+picnixz@users.noreply.github.com> Co-authored-by: Victor Stinner <vstinner@python.org>
* gh-71587: Drop local reference cache to `_strptime` module in `_datetime` ↵neonene2024-06-121-1/+0
| | | | | (gh-120224) The _strptime module object was cached in a static local variable (in the datetime.strptime() implementation). That's a problem when it crosses isolation boundaries, such as reinitializing the runtme or between interpreters. This change fixes the problem by dropping the static variable, instead always relying on the normal sys.modules cache (via PyImport_Import()).
* gh-117398: Use Per-Interpreter State for the _datetime Static Types (gh-119929)Eric Snow2024-06-032-0/+2
| | | | | | | We make use of the same mechanism that we use for the static builtin types. This required a few tweaks. The relevant code could use some cleanup but I opted to avoid the significant churn in this change. I'll tackle that separately. This change is the final piece needed to make _datetime support multiple interpreters. I've updated the module slot accordingly.
* gh-119396: Optimize unicode_repr() (#119617)Victor Stinner2024-05-281-0/+1

* gh-116738: Make `_codecs` module thread-safe (#117530)Brett Simmers2024-05-021-1/+1
| | | | | | | | | | | | | | | 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.
* gh-76785: Rename _xxsubinterpreters to _interpreters (gh-117791)Eric Snow2024-04-241-5/+5

* gh-76785: Drop PyInterpreterID_Type (gh-117101)Eric Snow2024-03-211-1/+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 Stinner2024-03-211-0/+1
| | | | | | | | | | | | 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-85283: Convert grp extension to the limited C API (#116611)Victor Stinner2024-03-121-0/+2
| | | | posixmodule.h: remove check on the limited C API, since these helpers are not part of the public C API.
* gh-116417: Fix make check-c-globals for _testlimitedcapi (#116570)Victor Stinner2024-03-102-1/+1
| | | | | * Remove unused '_testcapimodule' global in Modules/_testcapi/unicode.c. * Update c-analyzer to not use the internal C API in _testlimitedcapi.c.
* gh-116417: Add _testlimitedcapi C extension (#116419)Victor Stinner2024-03-071-2/+2
| | | | | | | | | | | | | Add a new C extension "_testlimitedcapi" which is only built with the limited C API. Move heaptype_relative.c and vectorcall_limited.c from Modules/_testcapi/ to Modules/_testlimitedcapi/. * configure: add _testlimitedcapi test extension. * Update generate_stdlib_module_names.py. * Update make check-c-globals.

* gh-110850: Rename internal PyTime C API functions (#115734)Victor Stinner2024-02-201-0/+1
| | | | | | | | | | | | | | | | | Rename functions: * _PyTime_GetSystemClock() => _PyTime_TimeUnchecked() * _PyTime_GetPerfCounter() => _PyTime_PerfCounterUnchecked() * _PyTime_GetMonotonicClock() => _PyTime_MonotonicUnchecked() * _PyTime_GetSystemClockWithInfo() => _PyTime_TimeWithInfo() * _PyTime_GetMonotonicClockWithInfo() => _PyTime_MonotonicWithInfo() * _PyTime_GetMonotonicClockWithInfo() => _PyTime_MonotonicWithInfo() Changes: * Remove "typedef PyTime_t PyTime_t;" which was "typedef PyTime_t _PyTime_t;" before a previous rename. * Update comments of "Unchecked" functions. * Remove invalid PyTime_Time() comment.

| | | | | | | | | | | | | | | | | Add PythonFinalizationError exception. This exception derived from RuntimeError is raised when an operation is blocked during the Python finalization. The following functions now raise PythonFinalizationError, instead of RuntimeError: * _thread.start_new_thread() * subprocess.Popen * os.fork() * os.fork1() * os.forkpty() Morever, _winapi.Overlapped finalizer now logs an unraisable PythonFinalizationError, instead of an unraisable RuntimeError.

* gh-76785: Improved Subinterpreters Compatibility with 3.12 (gh-115424)Eric Snow2024-02-131-4/+4
| | | | | For the most part, these changes make is substantially easier to backport subinterpreter-related code to 3.12, especially the related modules (e.g. _xxsubinterpreters). The main motivation is to support releasing a PyPI package with the 3.13 capabilities compiled for 3.12. A lot of the changes here involve either hiding details behind macros/functions or splitting up some files.

* gh-113055: Use pointer for interp->obmalloc state (gh-113412)Neil Schemenauer2024-01-271-1/+2
| | | | | | | | | For interpreters that share state with the main interpreter, this points to the same static memory structure. For interpreters with their own obmalloc state, it is heap allocated. Add free_obmalloc_arenas() which will free the obmalloc arenas and radix tree structures for interpreters with their own obmalloc state. Co-authored-by: Eric Snow <ericsnowcurrently@gmail.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Add mimalloc v2.12 Modified src/alloc.c to remove include of alloc-override.c and not compile new handler. Did not include the following files: - include/mimalloc-new-delete.h - include/mimalloc-override.h - src/alloc-override-osx.c - src/alloc-override.c - src/static.c - src/region.c mimalloc is thread safe and shares a single heap across all runtimes, therefore finalization and getting global allocated blocks across all runtimes is different. * mimalloc: minimal changes for use in Python: - remove debug spam for freeing large allocations - use same bytes (0xDD) for freed allocations in CPython and mimalloc This is important for the test_capi debug memory tests * Don't export mimalloc symbol in libpython. * Enable mimalloc as Python allocator option. * Add mimalloc MIT license. * Log mimalloc in Lib/test/pythoninfo.py. * Document new mimalloc support. * Use macro defs for exports as done in: https://github.com/python/cpython/pull/31164/ Co-authored-by: Sam Gross <colesbury@gmail.com> Co-authored-by: Christian Heimes <christian@python.org> Co-authored-by: Victor Stinner <vstinner@python.org>
