* gh-115015: Argument Clinic: fix generated code for METH_METHOD methods ↵Erlend E. Aasland2024-02-051-0/+1
| | | | without params (#115016)
* gh-113744: Add a new IncompleteInputError exception to improve incomplete ↵Pablo Galindo Salgado2024-01-301-0/+2

* 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>
* gh-89532: Remove LibreSSL workarounds (#28728)Rami2024-01-061-2/+1
| | | | | | Remove LibreSSL specific workaround ifdefs from `_ssl.c` and delete the non-version-specific `_ssl_data.h` file (relevant for OpenSSL < 1.1.1, which we no longer support per PEP 644).

* gh-76785: More Fixes for test.support.interpreters (gh-113012)Eric Snow2023-12-121-0/+1
| | | This brings the module (along with the associated extension modules) mostly in sync with PEP 734. There are only a few small things to wrap up.
* gh-76785: Fixes for test.support.interpreters (gh-112982)Eric Snow2023-12-121-0/+4
| | | This involves a number of changes for PEP 734.

* gh-90815: Add mimalloc memory allocator (#109914)Dino Viehland2023-10-302-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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>

* gh-104169: Refactor tokenizer into lexer and wrappers (#110684)Lysandros Nikolaou2023-10-111-1/+1
| | | | | | | | | | | * The lexer, which include the actual lexeme producing logic, goes into the `lexer` directory. * The wrappers, one wrapper per input mode (file, string, utf-8, and readline), go into the `tokenizer` directory and include logic for creating a lexer instance and managing the buffer for different modes. --------- Co-authored-by: Pablo Galindo <pablogsal@gmail.com> Co-authored-by: blurb-it[bot] <43283697+blurb-it[bot]@users.noreply.github.com>

* gh-109723: Disable Py_BUILD_CORE in _testcapi (#109727)Victor Stinner2023-09-221-6/+11
| | | | | | | | | | | | | | | | | | Make sure that the internal C API is not tested by mistake by _testcapi. Undefine Py_BUILD_CORE_BUILTIN and Py_BUILD_CORE_MODULE macros in Modules/_testcapi/parts.h: move code from _testcapimodule.c. heaptype_relative.c and vectorcall_limited.c are using the limited C API which is incompatible with the internal C API. Move test_long_numbits() from _testcapi to _testinternalcapi since it uses the internal C API "pycore_long.h". Fix Modules/_testcapi/pyatomic.c: don't include Python.h directly, just include _testcapi/parts.h. Ajust "make check-c-globals" for these changes.
* gh-104469: Disallow using Py_LIMITED_API with Py_BUILD_CORE (#109690)Victor Stinner2023-09-211-2/+7
| | | | Fix make check-c-globals: complete USE_LIMITED_C_API list of the c-analyzer.
* gh-108724: Add PyMutex and _PyParkingLot APIs (gh-109344)Sam Gross2023-09-192-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | PyMutex is a one byte lock with fast, inlineable lock and unlock functions for the common uncontended case. The design is based on WebKit's WTF::Lock. PyMutex is built using the _PyParkingLot APIs, which provides a cross-platform futex-like API (based on WebKit's WTF::ParkingLot). This internal API will be used for building other synchronization primitives used to implement PEP 703, such as one-time initialization and events. This also includes tests and a mini benchmark in Tools/lockbench/lockbench.py to compare with the existing PyThread_type_lock. Uncontended acquisition + release: * Linux (x86-64): PyMutex: 11 ns, PyThread_type_lock: 44 ns * macOS (arm64): PyMutex: 13 ns, PyThread_type_lock: 18 ns * Windows (x86-64): PyMutex: 13 ns, PyThread_type_lock: 38 ns PR Overview: The primary purpose of this PR is to implement PyMutex, but there are a number of support pieces (described below). * PyMutex: A 1-byte lock that doesn't require memory allocation to initialize and is generally faster than the existing PyThread_type_lock. The API is internal only for now. * _PyParking_Lot: A futex-like API based on the API of the same name in WebKit. Used to implement PyMutex. * _PyRawMutex: A word sized lock used to implement _PyParking_Lot. * PyEvent: A one time event. This was used a bunch in the "nogil" fork and is useful for testing the PyMutex implementation, so I've included it as part of the PR. * pycore_llist.h: Defines common operations on doubly-linked list. Not strictly necessary (could do the list operations manually), but they come up frequently in the "nogil" fork.

* gh-107782: Use _testcapi to test non-representable signatures (GH-109325)Serhiy Storchaka2023-09-141-0/+1
| | | | | | | | | Builtin functions and methods that have non-representable signatures today will have representable signatures yesterday, and they will become unusable for testing this feature. So we need to add special functions and methods to the _testcapi module that always have non-representable signatures.
* gh-106320: Remove _PyAnextAwaitable_Type from the public C API (#108597)Victor Stinner2023-08-292-3/+2
| | | | It's not needed to declare it in Include/iterobject.h: just use "extern" where it's used (only in object.c).
* gh-106320: Remove private AC converter functions (#108505)Victor Stinner2023-08-261-21/+10
| | | | | | | | | | | | | | Move these private functions to the internal C API (pycore_abstract.h): * _Py_convert_optional_to_ssize_t() * _PyNumber_Index() Argument Clinic now emits #include "pycore_abstract.h" when these functions are used. The parser of the c-analyzer tool now uses a list of files which use the limited C API, rather than a list of files using the internal C API.
* gh-106320: Remove private _PyLong_FileDescriptor_Converter() (#108503)Victor Stinner2023-08-261-1/+4
| | | | | | | | | Move the private _PyLong converter functions to the internal C API * _PyLong_FileDescriptor_Converter(): moved to pycore_fileutils.h * _PyLong_Size_t_Converter(): moved to pycore_long.h Argument Clinic now emits includes for pycore_fileutils.h and pycore_long.h when these functions are used.
* gh-106320: Remove private _PyLong converter functions (#108499)Victor Stinner2023-08-261-0/+9
| | | | | | | | | | | Move these private functions to the internal C API (pycore_long.h): * _PyLong_UnsignedInt_Converter() * _PyLong_UnsignedLongLong_Converter() * _PyLong_UnsignedLong_Converter() * _PyLong_UnsignedShort_Converter() Argument Clinic now emits #include "pycore_long.h" when these functions are used.
