bpo-40412: Nullify inittab_copy during finalization (GH-19746)

2020-05-01T23:06:23+00:00

Otherwise we leave a dangling pointer to free'd memory. If we
then initialize a new interpreter in the same process and call
PyImport_ExtendInittab, we will (likely) crash when calling
PyMem_RawRealloc(inittab_copy, ...) since the pointer address
is bogus.

[3.8] bpo-39562: Prevent collision of future and compiler flags (GH-19230) (GH-19835)

2020-05-01T14:18:27+00:00

The constant values of future flags in the __future__ module
is updated in order to prevent collision with compiler flags.
Previously PyCF_ALLOW_TOP_LEVEL_AWAIT was clashing
with CO_FUTURE_DIVISION..

bpo-40048: Fix _PyCode_InitOpcache() error path (GH-19691) (GH-19698)

2020-04-24T01:07:20+00:00

If _PyCode_InitOpcache() fails in _PyEval_EvalFrameDefault(), use
"goto exit_eval_frame;" rather than "return NULL;" to exit the
function in a consistent state. For example, tstate->frame is now
reset properly.

Document most common signals (GH-19245) (GH-19257)

Document individual signals (only the most common signals):
description, default action, availability.

bpo-20526: Fix PyThreadState_Clear(): don't decref frame (GH-19120) (GH-19136)

2020-03-24T16:12:19+00:00

PyThreadState.frame is a borrowed reference, not a strong reference:
PyThreadState_Clear() must not call Py_CLEAR(tstate->frame).

Remove test_threading.test_warnings_at_exit(): we cannot warranty
that the Python thread state of daemon threads is cleared in a
reliable way during Python shutdown.

bpo-22490: Remove __PYVENV_LAUNCHER__ from environment during launch (GH-9516) (GH-19110)

2020-03-22T18:56:26+00:00

* bpo-22490: Remove "__PYVENV_LAUNCHER__" from the shell environment on macOS

This changeset removes the environment varialbe "__PYVENV_LAUNCHER__"
during interpreter launch as it is only needed to communicate between
the stub executable in framework installs and the actual interpreter.

Leaving the environment variable present may lead to misbehaviour when
launching other scripts.

* Actually commit the changes for issue 22490...

* Correct typo
