bpo-39430: Fix race condition in lazy imports in tarfile. (GH-18161)

2020-01-24T17:55:52+00:00

Use `from ... import ...` to ensure module is fully loaded before accessing its attributes.

bpo-38631: Avoid Py_FatalError() in GC collect() (GH-18164)

2020-01-24T17:05:24+00:00

collect() should not get an exception, but it does, logging the
exception is enough. Override sys.unraisablehook to decide how to
handle unraisable exceptions.

Py_FatalError() should be avoided whenever possible.

bpo-39395: putenv() and unsetenv() always available (GH-18135)

2020-01-24T13:05:48+00:00

The os.putenv() and os.unsetenv() functions are now always available.

On non-Windows platforms, Python now requires setenv() and unsetenv()
functions to build.

Remove putenv_dict from posixmodule.c: it's not longer needed.

bpo-39413: Implement os.unsetenv() on Windows (GH-18163)

2020-01-24T10:53:44+00:00

The os.unsetenv() function is now also available on Windows.

2020-01-24T10:03:22+00:00

Some portions of the pickle documentation hadn't been updated for the pickle protocol changes in Python 3.8 (new protocol 5, default protocol 4). This PR fixes those docs.
