* [3.11] C-API docs: Clarify the size of arenas (GH-110895) (#110947)Miss Islington (bot)2023-10-161-1/+2
| | | | | | | | | | | C-API docs: Clarify the size of arenas (GH-110895) Clarify the size of arenas From 3.10.0 alpha 7, the pymalloc allocator uses arenas with a fixed size of 1 MiB on 64-bit platforms instead of 256 KiB on 32-bit platforms. (cherry picked from commit f07ca27709855d4637b43bba23384cc795143ee3) Co-authored-by: Mienxiu <82512658+mienxiu@users.noreply.github.com>

| | | | | | | | | | | | | | | | | | | | * Fix _PyMem_SetupAllocators("debug"): always restore allocators to the defaults, rather than only caling _PyMem_SetupDebugHooks(). * Add _PyMem_SetDefaultAllocator() helper to set the "default" allocator. * Add _PyMem_GetAllocatorsName(): get the name of the allocators * main() now uses debug hooks on memory allocators if Py_DEBUG is defined, rather than calling directly malloc() * Document default memory allocators in C API documentation * _Py_InitializeCore() now fails with a fatal user error if PYTHONMALLOC value is an unknown memory allocator, instead of failing with a fatal internal error. * Add new tests on the PYTHONMALLOC environment variable * Add support.with_pymalloc() * Add the _testcapi.WITH_PYMALLOC constant and expose it as support.with_pymalloc(). * sysconfig.get_config_var('WITH_PYMALLOC') doesn't work on Windows, so replace it with support.with_pymalloc(). * pythoninfo: add _testcapi collector for pymem
* Replace KB unit with KiB (#4293)Victor Stinner2017-11-081-1/+1
| | | | | | | | | | | kB (*kilo* byte) unit means 1000 bytes, whereas KiB ("kibibyte") means 1024 bytes. KB was misused: replace kB or KB with KiB when appropriate. Same change for MB and GB which become MiB and GiB. Change the output of Tools/iobench/iobench.py. Round also the size of the documentation from 5.5 MB to 5 MiB.

* PyMem_Malloc() now uses the fast pymalloc allocatorVictor Stinner2016-04-221-23/+37
| | | | | | | Issue #26249: PyMem_Malloc() allocator family now uses the pymalloc allocator rather than system malloc(). Applications calling PyMem_Malloc() without holding the GIL can now crash: use PYTHONMALLOC=debug environment variable to validate the usage of memory allocators in your application.

| | | | | | | | | | | | | Issue #26516: * Add PYTHONMALLOC environment variable to set the Python memory allocators and/or install debug hooks. * PyMem_SetupDebugHooks() can now also be used on Python compiled in release mode. * The PYTHONMALLOCSTATS environment variable can now also be used on Python compiled in release mode. It now has no effect if set to an empty string. * In debug mode, debug hooks are now also installed on Python memory allocators when Python is configured without pymalloc.
* Issue #26516: Enhance Python mem allocators docVictor Stinner2016-03-091-43/+77
| | | | | | | * add link to PYTHONMALLOCSTATS env var * add parameters to PyMem macros like PyMem_MALLOC() * fix PyMem_SetupDebugHooks(): add Calloc functions * add some newlines for readability

|/ | | | | | PyObject_Calloc(), _PyObject_GC_Calloc(). bytes(int) and bytearray(int) are now using ``calloc()`` instead of ``malloc()`` for large objects which is faster and use less memory (until the bytearray buffer is filled with data).
* Issue #18874: _PyObject_Malloc/Realloc/Free() now falls back onVictor Stinner2013-10-101-2/+2
| | | | | | _PyMem_RawMalloc/Realloc/Free, instead of _PyMem_Malloc/Realloc/Free. So it becomes possible to use the fast pymalloc allocator for the PYMEM_DOMAIN_MEM domain (PyMem_Malloc/Realloc/Free functions).
