* bpo-46906: Add PyFloat_Pack8() to the C API (GH-31657)Victor Stinner2022-03-111-0/+82
| | | | | | | | | | | | | | | | | | | | | | Add new functions to pack and unpack C double (serialize and deserialize): * PyFloat_Pack2(), PyFloat_Pack4(), PyFloat_Pack8() * PyFloat_Unpack2(), PyFloat_Unpack4(), PyFloat_Unpack8() Document these functions and add unit tests. Rename private functions and move them from the internal C API to the public C API: * _PyFloat_Pack2() => PyFloat_Pack2() * _PyFloat_Pack4() => PyFloat_Pack4() * _PyFloat_Pack8() => PyFloat_Pack8() * _PyFloat_Unpack2() => PyFloat_Unpack2() * _PyFloat_Unpack4() => PyFloat_Unpack4() * _PyFloat_Unpack8() => PyFloat_Unpack8() Replace the "unsigned char*" type with "char*" which is more common and easy to use.

* bpo-46836: Move PyFrameObject to pycore_frame.h (GH-31530)Victor Stinner2022-02-251-2/+10
| | | | Move the PyFrameObject type definition (struct _frame) to the internal C API pycore_frame.h header file.
* bpo-40421: Fix PyFrame_GetCode() documentation (GH-31535)Victor Stinner2022-02-231-2/+2

* Minor fixes to C API docs (GH-31501)Jelle Zijlstra2022-02-234-24/+28
| | | | | | | | | | | | | | | | * C API docs: move PyErr_SetImportErrorSubclass docs It was in the section about warnings, but it makes more sense to put it with PyErr_SetImportError. * C API docs: document closeit argument to PyRun_AnyFileExFlags It was already documented for PyRun_SimpleFileExFlags. * textual fixes to unicode docs * Move paragraph about tp_dealloc into tp_dealloc section * __aiter__ returns an async iterator, not an awaitable
* bpo-46613: Add PyType_GetModuleByDef to the public API (GH-31081)Petr Viktorin2022-02-111-0/+17

* bpo-46608: exclude marshalled-frozen data if deep-freezing to save 300 KB ↵Kumar Aditya2022-02-041-0/+4
| | | | | | | | | | | | | space (GH-31074) This reduces the size of the data segment by **300 KB** of the executable because if the modules are deep-frozen then the marshalled frozen data just wastes space. This was inspired by comment by @gvanrossum in https://github.com/python/cpython/pull/29118#issuecomment-958521863. Note: There is a new option `--deepfreeze-only` in `freeze_modules.py` to change this behavior, it is on be default to save disk space. ```console # du -s ./python before 27892 ./python # du -s ./python after 27524 ./python ``` Automerge-Triggered-By: GH:ericsnowcurrently

* bpo-43931: Export Python version as API data (GH-25577)Gabriele N. Tornetta2021-12-102-0/+11
| | | | | When Python is embedded in other applications, it is not easy to determine which version of Python is being used. This change exposes the Python version as part of the API data. Tools like Austin (https://github.com/P403n1x87/austin) can benefit from this data when targeting applications like uWSGI, as the Python version can then be inferred systematically by looking at the exported symbols rather than relying on unreliable pattern matching or other hacks (like remote code execution etc...).

* bpo-45582: Port getpath[p].c to Python (GH-29041)Steve Dower2021-12-031-13/+28
| | | | | 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-45954: Rename PyConfig.no_debug_ranges to code_debug_ranges (GH-29886)Victor Stinner2021-12-021-3/+6

| | | | | required by CPython (GH-29170) It is now considered a historical accident that e.g. `for` loops and the `iter()` built-in function do not require the iterators they work with to define `__iter__`, only `__next__`.
* bpo-28737: Document when tp_dealloc should call PyObject_GC_UnTrack() (GH-29246)Sam Gross2021-10-272-8/+20
| | | | | Objects that support garbage collection ("container" objects) should call PyObject_GC_UnTrack() from their destructors before clearing any fields which may point to other "container" objects.

| | | | | | | | | | Add PyThreadState_EnterTracing() and PyThreadState_LeaveTracing() functions to the limited C API to suspend and resume tracing and profiling. Add an unit test on the PyThreadState C API to _testcapi. Add also internal _PyThreadState_DisableTracing() and _PyThreadState_ResetTracing().

* bpo-45116: Add the Py_ALWAYS_INLINE macro (GH-28390)Victor Stinner2021-09-171-0/+19
