[New-bugs-announce] [issue19410] Restore empty string special casing in importlib.machinery.FileFinder

[Nick Coghlan]

New submission from Nick Coghlan:

As noted on python-dev, while changing PathFinder to expand the empty string to the current working directory is a good idea, removing the '' special case handling in FileFinder may break subclasses and other custom metapath hooks that expect the current behaviour.

Just creating this to make sure it is resolved before 3.4 is released (it is simply a matter of reverting a patch, since we want to keep *most* of the change that implemented absolute paths in __file__ attributes, just not all of it)
