 bpo-35081: Add _PyThreadState_GET() internal macro (GH-10266) 2018-11-01T00:51:40+00:00 Victor Stinner vstinner@redhat.com 2018-11-01T00:51:40+00:00 50b48572d9a90c5bb36e2bef6179548ea927a35a If Py_BUILD_CORE is defined, the PyThreadState_GET() macro access _PyRuntime which comes from the internal pycore_state.h header. Public headers must not require internal headers. Move PyThreadState_GET() and _PyInterpreterState_GET_UNSAFE() from Include/pystate.h to Include/internal/pycore_state.h, and rename PyThreadState_GET() to _PyThreadState_GET() there. The PyThreadState_GET() macro of pystate.h is now redefined when pycore_state.h is included, to use the fast _PyThreadState_GET(). Changes: * Add _PyThreadState_GET() macro * Replace "PyThreadState_GET()->interp" with _PyInterpreterState_GET_UNSAFE() * Replace PyThreadState_GET() with _PyThreadState_GET() in internal C files (compiled with Py_BUILD_CORE defined), but keep PyThreadState_GET() in the public header files. * _testcapimodule.c: replace PyThreadState_GET() with PyThreadState_Get(); the module is not compiled with Py_BUILD_CORE defined. * pycore_state.h now requires Py_BUILD_CORE to be defined.

Public headers must not require internal headers.

Move PyThreadState_GET() and _PyInterpreterState_GET_UNSAFE() from
Include/pystate.h to Include/internal/pycore_state.h, and rename
PyThreadState_GET() to _PyThreadState_GET() there.

The PyThreadState_GET() macro of pystate.h is now redefined when
pycore_state.h is included, to use the fast _PyThreadState_GET().

Changes:

* Add _PyThreadState_GET() macro
* Replace "PyThreadState_GET()->interp" with
  _PyInterpreterState_GET_UNSAFE()
* Replace PyThreadState_GET() with _PyThreadState_GET() in internal C
  files (compiled with Py_BUILD_CORE defined), but keep
  PyThreadState_GET() in the public header files.
* _testcapimodule.c: replace PyThreadState_GET() with
  PyThreadState_Get(); the module is not compiled with Py_BUILD_CORE
  defined.
* pycore_state.h now requires Py_BUILD_CORE to be defined.

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.

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.

See also the PEP 475. The pthread implementation of PyThread_acquire_lock() now fails with a fatal error if the timeout is larger than PY_TIMEOUT_MAX, as done in the Windows implementation.

CPython has provided the own implementation for thread-local storage
(TLS) on Python/thread.c, it's used in the case which a platform has
not supplied native TLS.  However, currently all supported platforms
(NT and pthreads) have provided native TLS and defined the
Py_HAVE_NATIVE_TLS macro with unconditional in any case.
