* GH-91432: Specialize FOR_ITER (GH-91713)Dennis Sweeney2022-06-211-0/+1
| | | | | * Adds FOR_ITER_LIST and FOR_ITER_RANGE specializations. * Adds _PyLong_AssignValue() internal function to avoid temporary boxing of ints.
* gh-93937, C API: Move PyFrame_GetBack() to Python.h (#93938)Victor Stinner2022-06-191-0/+1
| | | | | | | | | | | | | | | | Move the follow functions and type from frameobject.h to pyframe.h, so the standard <Python.h> provide frame getter functions: * PyFrame_Check() * PyFrame_GetBack() * PyFrame_GetBuiltins() * PyFrame_GetGenerator() * PyFrame_GetGlobals() * PyFrame_GetLasti() * PyFrame_GetLocals() * PyFrame_Type Remove #include "frameobject.h" from many C files. It's no longer needed.
* gh-93911: Specialize `LOAD_ATTR_PROPERTY` (GH-93912)Ken Jin2022-06-171-0/+1

* Improve object stats (#92845)Mark Shannon2022-05-161-0/+1
| | | | | * Add incref/decref stats * Show ratios for allocation in summary
* gh-92651: Remove the Include/token.h header file (#92652)Victor Stinner2022-05-111-1/+1
| | | | | | | | | | | | | | | Remove the token.h header file. There was never any public tokenizer C API. The token.h header file was only designed to be used by Python internals. Move Include/token.h to Include/internal/pycore_token.h. Including this header file now requires that the Py_BUILD_CORE macro is defined. It no longer checks for the Py_LIMITED_API macro. Rename functions: * PyToken_OneChar() => _PyToken_OneChar() * PyToken_TwoChars() => _PyToken_TwoChars() * PyToken_ThreeChars() => _PyToken_ThreeChars()
* gh-64783: Fix signal.NSIG value on FreeBSD (#91929)Victor Stinner2022-04-251-0/+1
| | | | | | | | | Fix signal.NSIG value on FreeBSD to accept signal numbers greater than 32, like signal.SIGRTMIN and signal.SIGRTMAX. * Add Py_NSIG constant. * Add pycore_signal.h internal header file. * _Py_Sigset_Converter() now includes the range of valid signals in the error message.
* gh-79315: Add Include/cpython/pythread.h header (#91798)Victor Stinner2022-04-211-0/+1
|
* gh-79315: Add Include/cpython/modsupport.h header (#91797)Victor Stinner2022-04-211-0/+1
|
* bpo-35134: Remove the Include/code.h header file (GH-32385)Victor Stinner2022-04-071-1/+0
| | | | | | Remove the Include/code.h header file. C extensions should only include the main <Python.h> header file. Python.h includes directly Include/cpython/code.h instead.
* bpo-35134: Add Include/cpython/setobject.h header (GH-32384)Victor Stinner2022-04-061-0/+1
|
* bpo-35134: Add Include/cpython/complexobject.h header (GH-32383)Victor Stinner2022-04-061-0/+1
| | | | Move the private _PyComplex_FormatAdvancedWriter() function to the internal C API. This function is no longer exported.
* bpo-47230: Silence compiler warnings on Windows from zlib 1.2.12 (GH-32337)Jeremy Kloth2022-04-051-2/+4
|
* bpo-47152: Move sources of the _sre module into a subdirectory (GH-32290)Serhiy Storchaka2022-04-041-4/+4
|
* bpo-38256: Fix binascii.crc32() when inputs are 4+GiB (GH-32000)Gregory P. Smith2022-03-201-1/+3
| | | | | | | When compiled with `USE_ZLIB_CRC32` defined (`configure` sets this on POSIX systems), `binascii.crc32(...)` failed to compute the correct value when the input data was >= 4GiB. Because the zlib crc32 API is limited to a 32-bit length. This lines it up with the `zlib.crc32(...)` implementation that doesn't have that flaw. **Performance:** This also adopts the same GIL releasing for larger inputs logic that `zlib.crc32` has, and causes the Windows build to always use zlib's crc32 instead of our slow C code as zlib is a required build dependency on Windows.
* bpo-46841: Use *inline* caching for `BINARY_OP` (GH-31543)Brandt Bucher2022-02-251-1/+0
|
* bpo-45459: Add pytypedefs.h header file (GH-31527)Victor Stinner2022-02-241-0/+1
| | | | | | | | | | | | | | | | | | Move forward declarations of Python C API types to a new pytypedefs.h header file to solve interdependency issues between header files. pytypedefs.h contains forward declarations of the following types: * PyCodeObject * PyFrameObject * PyGetSetDef * PyInterpreterState * PyLongObject * PyMemberDef * PyMethodDef * PyModuleDef * PyObject * PyThreadState * PyTypeObject
* bpo-45459: Rename buffer.h to pybuffer.h (#31201)Victor Stinner2022-02-221-0/+1
| | | | | | | | | Rename Include/buffer.h header file to Include/pybuffer.h to avoid conflicts with projects having an existing "buffer.h" header file. * Incude pybuffer.h before object.h in Python.h. * Remove #include "buffer.h" from Include/cpython/object.h. * Add a forward declaration of the PyObject type in pybuffer.h to fix an inter-dependency issue.
* bpo-35134: Add Include/cpython/descrobject.h (GH-30923)Victor Stinner2022-01-261-0/+1
| | | | Move Include/descrobject.h non-limited API to a new Include/cpython/descrobject.h header file.
* bpo-46429: Merge all deepfrozen files into one (GH-30572)Kumar Aditya2022-01-201-23/+1

* bpo-46370: Move the static initializer for _PyRuntime to its own header ↵Eric Snow2022-01-131-0/+1
| | | | | file. (gh-30587) https://bugs.python.org/issue46370
* bpo-45953: Statically initialize the small ints. (gh-30092)Eric Snow2021-12-141-1/+1
| | | | | | | The array of small PyLong objects has been statically declared. Here I also statically initialize them. Consequently they are no longer initialized dynamically during runtime init. I've also moved them under a new sub-struct in _PyRuntimeState, in preparation for static allocation and initialization of other global objects. https://bugs.python.org/issue45953
* bpo-45654: No need to freeze types (GH-30028)Christian Heimes2021-12-101-1/+0
|
* bpo-45582: Fix test_embed failure during a PGO build on Windows (GH-30014)neonene2021-12-101-2/+4
| | | This defines VPATH differently in PGO instrumentation builds, to account for a different default output directory. It also adds sys._vpath on Windows to make the value available to sysconfig so that it can be used in tests.
* bpo-46008: Make runtime-global object/type lifecycle functions and state ↵Eric Snow2021-12-091-0/+7
| | | | | | | | | | | | consistent. (gh-29998) This change is strictly renames and moving code around. It helps in the following ways: * ensures type-related init functions focus strictly on one of the three aspects (state, objects, types) * passes in PyInterpreterState * to all those functions, simplifying work on moving types/objects/state to the interpreter * consistent naming conventions help make what's going on more clear * keeping API related to a type in the corresponding header file makes it more obvious where to look for it https://bugs.python.org/issue46008
* bpo-45654: Freeze the runpy module and stuff it imports (GH-29903)Kumar Aditya2021-12-091-0/+4
|
* bpo-45816: Support building with VS 2022 (v143 toolset) on Windows (GH-29577)Crowthebird2021-12-031-1/+1
|
* bpo-45582: Port getpath[p].c to Python (GH-29041)Steve Dower2021-12-031-2/+19
| | | | | The getpath.py file is frozen at build time and executed as code over a namespace. It is never imported, nor is it meant to be importable or reusable. However, it should be easier to read, modify, and patch than the previous code. This commit attempts to preserve every previously tested quirk, but these may be changed in the future to better align platforms.
* bpo-44525: Copy free variables in bytecode to allow calls to inner functions ↵Mark Shannon2021-11-231-0/+1
| | | | | | | | | | | to be specialized (GH-29595) * Make internal APIs that take PyFrameConstructor take a PyFunctionObject instead. * Add reference to function to frame, borrow references to builtins and globals. * Add COPY_FREE_VARS instruction to allow specialization of calls to inner functions.
* bpo-45850: Implement deep-freeze on Windows (#29648)Guido van Rossum2021-11-221-0/+24
| | | | | | Implement changes to build with deep-frozen modules on Windows. Note that we now require Python 3.10 as the "bootstrap" or "host" Python. This causes a modest startup speed (around 7%) on Windows.
* Refactor parser compilation units into specific components (GH-29676)Pablo Galindo Salgado2021-11-211-0/+2
|
* bpo-45720: Drop references to shlwapi.dll on Windows (GH-29417)Steve Dower2021-11-051-1/+1
|
* bpo-45548: Remove _math.c workarounds for pre-C99 libm (GH-29179)Christian Heimes2021-10-251-1/+0
| | | | | | | | | | | | | The :mod:`math` and :mod:`cmath` implementation now require a C99 compatible ``libm`` and no longer ship with workarounds for missing acosh, asinh, expm1, and log1p functions. The changeset also removes ``_math.c`` and moves the last remaining workaround into ``_math.h``. This simplifies static builds with ``Modules/Setup`` and resolves symbol conflicts.

* bpo-35134: Add Include/cpython/longobject.h (GH-29044)Victor Stinner2021-10-191-0/+1
| | | | | | | | | | Move Include/longobject.h non-limited API to a new Include/cpython/longobject.h header file. Move the following definitions to the internal C API: * _PyLong_DigitValue * _PyLong_FormatAdvancedWriter() * _PyLong_FormatWriter()
* bpo-35134: Split warnings.h and weakrefobject.h (GH-29042)Victor Stinner2021-10-181-0/+2
| | | | | | | | | | | | | Split header files to move the non-limited API to Include/cpython/: * Include/warnings.h => Include/cpython/warnings.h * Include/weakrefobject.h => Include/cpython/weakrefobject.h Exclude PyWeakref_GET_OBJECT() from the limited C API. It never worked since the PyWeakReference structure is opaque in the limited C API. Move _PyWarnings_Init() and _PyErr_WarnUnawaitedCoroutine() to the internal C API.
* bpo-45482: Rename namespaceobject.h to pycore_namespace.h (GH-28975)Victor Stinner2021-10-151-1/+1
| | | | | | | | | Rename Include/namespaceobject.h to Include/internal/pycore_namespace.h. The _testmultiphase extension is now built with the Py_BUILD_CORE_MODULE macro defined to access _PyNamespace_Type. object.c: remove unused "pycore_context.h" include.
* bpo-45434: Remove Include/eval.h header file (GH-28973)Victor Stinner2021-10-151-1/+0
| | | | Move Include/eval.h content into Include/ceval.h and Include/cpython/ceval.h, and remove Include/eval.h.
* bpo-35081: Move interpreteridobject.h to Include/internal/ (GH-28969)Victor Stinner2021-10-151-2/+1
| | | | Move the interpreteridobject.h header file from Include/ to Include/internal/. It only provides private functions.
* bpo-35134: Move classobject.h to Include/cpython/ (GH-28968)Victor Stinner2021-10-151-4/+4
| | | | | | | | | Move classobject.h, context.h, genobject.h and longintrepr.h header files from Include/ to Include/cpython/. Remove redundant "#ifndef Py_LIMITED_API" in context.h. Remove explicit #include "longintrepr.h" in C files. It's not needed, Python.h already includes it.
* bpo-35134: Move Include/cellobject.h to Include/cpython/ (GH-28964)Victor Stinner2021-10-151-1/+1
|
* po-35134: Move Include/funcobject.h to Include/cpython/ (GH-28958)Victor Stinner2021-10-141-1/+1
| | | Remove redundant "#ifndef Py_LIMITED_API" in funcobject.h.
* bpo-35134: Add Include/cpython/floatobject.h (GH-28957)Victor Stinner2021-10-141-0/+2
| | | | | Split Include/floatobject.h into sub-files: add Include/cpython/floatobject.h and Include/internal/pycore_floatobject.h.
* bpo-45434: Remove pystrhex.h header file (GH-28923)Victor Stinner2021-10-131-1/+1
| | | | | | | | | | | | | | | Move Include/pystrhex.h to Include/internal/pycore_strhex.h. The header file only contains private functions. The following C extensions are now built with Py_BUILD_CORE_MODULE macro defined to get access to the internal C API: * _blake2 * _hashopenssl * _md5 * _sha1 * _sha3 * _ssl * binascii
* Add tests for the C tokenizer and expose it as a private module (GH-27924)Pablo Galindo Salgado2021-08-241-0/+1
|
* bpo-44590: Lazily allocate frame objects (GH-27077)Mark Shannon2021-07-261-0/+1
| | | | | | | | | | | | | | * Convert "specials" array to InterpreterFrame struct, adding f_lasti, f_state and other non-debug FrameObject fields to it. * Refactor, calls pushing the call to the interpreter upward toward _PyEval_Vector. * Compute f_back when on thread stack, only filling in value when frame object outlives stack invocation. * Move ownership of InterpreterFrame in generator from frame object to generator object. * Do not create frame objects for Python calls. * Do not create frame objects for generators.
* bpo-44611: Use BCryptGenRandom instead of CryptGenRandom on Windows (GH-27168)Dong-hee Na2021-07-231-1/+1
