| | | | | | | | | | | | | | | | | | | | | | | | | | 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 #26154: Add a new private _PyThreadState_UncheckedGet() function which gets the current thread state, but don't call Py_FatalError() if it is NULL. Python 3.5.1 removed the _PyThreadState_Current symbol from the Python C API to no more expose complex and private atomic types. Atomic types depends on the compiler or can even depend on compiler options. The new function _PyThreadState_UncheckedGet() allows to get the variable value without having to care of the exact implementation of atomic types. Changes: * Replace direct usage of the _PyThreadState_Current variable with a call to _PyThreadState_UncheckedGet(). * In pystate.c, replace direct usage of the _PyThreadState_Current variable with the PyThreadState_GET() macro for readability. * Document also PyThreadState_Get() in pystate.h
