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.
- don't call PyErr_NoMemory with interpreter is not initialised
- note that it's OK to call _PyMem_RawStrDup here
- don't include this in the limited API
- capitalise "IO"
- be explicit that a non-zero return indicates an error
- include versionadded marker in docs
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 new pre-initialization API allows embedding
applications like Blender to force a particular
encoding and error handler for the standard IO streams.
Also refactors Modules/_testembed.c to let us start
testing multiple embedding scenarios.
(Initial patch by Bastien Montagne)
This adds EmailMessage and, MIMEPart subclasses of Message
with new API methods, and a ContentManager class used by
the new methods. Also a new policy setting, content_manager.
Patch was reviewed by Stephen J. Turnbull and Serhiy Storchaka,
and reflects their feedback.
I will ideally add some examples of using the new API to the
documentation before the final release.
