bpo-40050: Fix importlib._bootstrap_external (GH-19135)

2020-03-24T17:03:34+00:00

Remove two unused imports: _thread and _weakref. Avoid creating a new
winreg builtin module if it's already available in sys.modules.

The winreg module is now stored as "winreg" rather than "_winreg".

bpo-39336: Allow packages to not let their child modules be set on them (#18006)

2020-01-23T00:42:38+00:00

* bpo-39336: Allow setattr to fail on modules which aren't assignable

When attaching a child module to a package if the object in sys.modules raises an AttributeError (e.g. because it is immutable) it causes the whole import to fail.  This now allows immutable packages to exist and an ImportWarning is reported and the AttributeError exception is ignored.
