* gh-130396: Move PYOS_LOG2_STACK_MARGIN to internal headers (#135928)Victor Stinner2025-07-011-23/+2
| | | | | | Move PYOS_LOG2_STACK_MARGIN, PYOS_STACK_MARGIN, PYOS_STACK_MARGIN_BYTES and PYOS_STACK_MARGIN_SHIFT macros to pycore_pythonrun.h internal header. Add underscore (_) prefix to the names to make them private. Rename _PYOS to _PyOS.
* GH-130397: remove special-casing of C stack depth for WASI (#134469)Brett Cannon2025-05-221-3/+0
| | | | | Removed special-casing for WASI when setting C stack depth limits. Since WASI has its own C stack checking this isn't a security risk. Also disabled some tests that stopped passing. They all happened to have already been disabled under Emscripten.

* bpo-43868: Remove PyOS_ReadlineFunctionPointer from the stable ABI list ↵Petr Viktorin2021-04-231-1/+0
| | | | | | | | | | | (GH-25442) The inclusion of PyOS_ReadlineFunctionPointer in python3dll.c was a mistake. According to PEP 384: > functions expecting FILE* are not part of the ABI, to avoid depending > on a specific version of the Microsoft C runtime DLL on Windows. https://bugs.python.org/issue43868
* bpo-43244: Remove symtable.h header file (GH-24910)Victor Stinner2021-03-191-5/+0
| | | | | | | | | | | | | | | | | | Rename Include/symtable.h to to Include/internal/pycore_symtable.h, don't export symbols anymore (replace PyAPI_FUNC and PyAPI_DATA with extern) and rename functions: * PyST_GetScope() to _PyST_GetScope() * PySymtable_BuildObject() to _PySymtable_Build() * PySymtable_Free() to _PySymtable_Free() Remove PySymtable_Build(), Py_SymtableString() and Py_SymtableStringObject() functions. The Py_SymtableString() function was part the stable ABI by mistake but it could not be used, since the symtable.h header file was excluded from the limited C API. The Python symtable module remains available and is unchanged.
* bpo-35134: Add Include/cpython/pythonrun.h file (GH-23701)Victor Stinner2020-12-081-117/+7
| | | | | Py_CompileString() is now always declared as a function by Include/pythonrun.h. It is overriden with a macro in Include/cpython/pythonrun.h.
* bpo-40939: Rename PyPegen* functions to PyParser* (GH-21016)Lysandros Nikolaou2020-06-211-50/+0
| | | | | | Rename PyPegen* functions to PyParser*, so that we can remove the old set of PyParser* functions that were using the old parser.
* bpo-37189: Export old PyRun_XXX() functions (#14142)Victor Stinner2019-06-171-2/+18
| | | | | Many PyRun_XXX() functions like PyRun_String() were no longer exported in libpython38.dll by mistake. Export them again to fix the ABI compatibiliy.
* bpo-37001: Makes symtable.symtable have parity with compile for input (#13483)Dino Viehland2019-05-281-0/+13
| | | | | | | * Makes symtable.symtable have parity for accepted datatypes for source code as compile() * Add NEWS blurb

* bpo-22257: Small changes for PEP 432. (#1728)Eric Snow2017-05-231-16/+0
| | | PEP 432 specifies a number of large changes to interpreter startup code, including exposing a cleaner C-API. The major changes depend on a number of smaller changes. This patch includes all those smaller changes.

* Issue #16129: Py_SetStandardStreamEncoding cleanupsNick Coghlan2013-10-181-0/+5
| | | | | | | | | - don't call PyErr_NoMemory with interpreter is not initialised - note that it's OK to call _PyMem_RawStrDup here - don't include this in the limited API - capitalise "IO" - be explicit that a non-zero return indicates an error - include versionadded marker in docs

* Issue #16129: Add `Py_SetStandardStreamEncoding`Nick Coghlan2013-10-171-0/+2
| | | | | | | | | | | This new pre-initialization API allows embedding applications like Blender to force a particular encoding and error handler for the standard IO streams. Also refactors Modules/_testembed.c to let us start testing multiple embedding scenarios. (Initial patch by Bastien Montagne)

| | | | | | | importlib._bootstrap is now frozen into Python/importlib.h and stored as _frozen_importlib in sys.modules. Py_Initialize() loads the frozen code along with sys and imp and then uses _frozen_importlib._install() to set builtins.__import__() w/ _frozen_importlib.__import__().
