* bpo-45459: C API uses type names rather than structure names (GH-31528)Victor Stinner2022-02-241-1/+1
| | | | Thanks to the new pytypedefs.h, it becomes to use type names like PyObject rather like structure names like "struct _object".
* bpo-46608: exclude marshalled-frozen data if deep-freezing to save 300 KB ↵Kumar Aditya2022-02-041-0/+1
| | | | | | | | | | | | | 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-45696: Deep-freeze selected modules (GH-29118)Guido van Rossum2021-11-111-0/+1
| | | | | | | This gains 10% or more in startup time for `python -c pass` on UNIX-ish systems. The Makefile.pre.in generating code builds on Eric's work for bpo-45020, but the .c file generator is new. Windows version TBD.

* bpo-39583: Remove superfluous "extern C" bits from Include/cpython/*.h ↵Skip Montanaro2020-06-011-8/+0

* bpo-36710: Add tstate parameter in import.c (GH-14218)Victor Stinner2019-06-191-8/+1
| | | | | | | | | | | | | * Add 'tstate' parameter to many internal import.c functions. * _PyImportZip_Init() now gets 'tstate' parameter rather than 'interp'. * Add 'interp' parameter to _PyState_ClearModules() and rename it to _PyInterpreterState_ClearModules(). * Move private _PyImport_FindBuiltin() to the internal C API; add 'tstate' parameter to it. * Remove private _PyImport_AddModuleObject() from the C API: use public PyImport_AddModuleObject() instead. * Remove private _PyImport_FindExtensionObjectEx() from the C API: use private _PyImport_FindExtensionObject() instead.
* bpo-35134: Add Include/cpython/import.h header file (GH-14213)Victor Stinner2019-06-181-0/+57
* Add Include/cpython/import.h and Include/internal/pycore_import.h header files. * Move _PyImport_ReInitLock() to the internal C API. Don't export the symbol anymore.
