bpo-39008: Require Py_ssize_t for PySys_Audit formats rather than raise a deprecation warning (GH-17540)

bpo-38317: Fix PyConfig.warnoptions priority (GH-16478)

2019-09-29T23:58:57+00:00

Fix warnings options priority: PyConfig.warnoptions has the highest
priority, as stated in the PEP 587.

* Document options order in PyConfig.warnoptions documentation.
* Make PyWideStringList_INIT macro private: replace "Py" prefix
  with "_Py".
* test_embed: add test_init_warnoptions().

[3.8] bpo-37206: Unrepresentable default values no longer represented as None. (GH-13933) (GH-16141)

2019-09-14T10:31:50+00:00

In ArgumentClinic, value "NULL" should now be used only for unrepresentable default values
(like in the optional third parameter of getattr). "None" should be used if None is accepted
as argument and passing None has the same effect as not passing the argument at all.

bpo-36763: PyConfig_Read() handles PySys_AddXOption() (GH-15431) (GH-15435)

2019-08-23T19:16:51+00:00

PyConfig_Read() is now responsible to handle early calls to
PySys_AddXOption() and PySys_AddWarnOption().

Options added by PySys_AddXOption() are now handled the same way than
PyConfig.xoptions and command line -X options.

For example, PySys_AddXOption(L"faulthandler") enables faulthandler
as expected.

bpo-37926: Fix PySys_SetArgvEx(0, NULL, 0) crash (GH-15415) (GH-15420)

2019-08-23T11:22:14+00:00

empty_argv is no longer static in Python 3.8, but it is declared in
a temporary scope, whereas argv keeps a reference to it.
empty_argv memory (allocated on the stack) is reused by
make_sys_argv() code which is inlined when using gcc -O3.

Define empty_argv in PySys_SetArgvEx() body, to ensure
that it remains valid for the whole lifetime of
the PySys_SetArgvEx() call.

bpo-37369: Fix initialization of sys members when launched via an app container (GH-14467)

2019-06-29T21:28:59+00:00

sys._base_executable is now always defined on all platforms, and can be overridden through configuration.
Also adds test.support.PythonSymlink to encapsulate platform-specific logic for symlinking sys.executable
