Issue #18416 : Have importlib.machinery.PathFinder treat '' as the cwd
...
and stop importlib.machinery.FileFinder treating '' as '.'.
Previous PathFinder transformed '' into '.' which led to __file__ for
modules imported from the cwd to always be relative paths. This meant
the values of the attribute were wrong as soon as the cwd changed.
This change now means that as long as the site module is run (which
makes all entries in sys.path absolute) then all values for __file__
will also be absolute unless it's for __main__ when specified by file
path in a relative way (modules imported by runpy will have an
absolute path).
Now that PathFinder is no longer treating '' as '.' it only makes
sense for FileFinder to stop doing so as well. Now no transformation
is performed for the directory given to the __init__ method.
Thanks to Madison May for the initial patch.

Close #19030 : inspect.getmembers and inspect.classify_class_attrs
...
Order of search is now:
1. Try getattr
2. If that throws an exception, check __dict__ directly
3. If still not found, walk the mro looking for the eldest class that has
the attribute (e.g. things returned by __getattr__)
4. If none of that works (e.g. due to a buggy __dir__, __getattr__, etc.
method or missing __slot__ attribute), ignore the attribute entirely.

This adds EmailMessage and, MIMEPart subclasses of Message

Close #16742 : Fix misuse of memory allocations in PyOS_Readline()
...
The GIL must be held to call PyMem_Malloc(), whereas PyOS_Readline() releases
the GIL to read input.
The result of the C callback PyOS_ReadlineFunctionPointer must now be a string
allocated by PyMem_RawMalloc() or PyMem_RawRealloc() (or NULL if an error
occurred), instead of a string allocated by PyMem_Malloc() or PyMem_Realloc().
Fixing this issue was required to setup a hook on PyMem_Malloc(), for example
using the tracemalloc module.
PyOS_Readline() copies the result of PyOS_ReadlineFunctionPointer() into a new
buffer allocated by PyMem_Malloc(). So the public API of PyOS_Readline() does
not change.

#14984 : On POSIX, enforce permissions when reading default .netrc.
...
Initial patch by Bruno Piguet.

does not support it. Fixing that issue will be an enhancement.
