Add importlib.machinery with its first tenants, BuitinImporter and FrozenImporter. Docs forthcoming. I plan on all finders and loaders (and most likely hooks) to live in imoprtlib.machinery. Utility stuff will end up in importlib.util. Higher-level API stuff will stay on imoprtlib directly (e.g. import_module). 2009-01-22 22:43:07 +00:00			`"""The machinery of importlib: finders, loaders, hooks, etc."""`

Issue #13959: Deprecate imp.get_suffixes() for new attributes on importlib.machinery that provide the suffix details for import. The attributes were not put on imp so as to compartmentalize everything importlib needs for setting up imports in importlib.machinery. This also led to an indirect deprecation of inspect.getmoduleinfo() as it directly returned imp.get_suffix's returned tuple which no longer makes sense. 2012-05-11 12:58:42 -04:00			`import _imp`

Check in the fact that importlib.machinery.PathFinder now exists. 2009-02-05 02:52:57 +00:00			`from ._bootstrap import PathFinder`
Issue #14605: Expose importlib.abc.FileLoader and importlib.machinery.(FileFinder, SourceFileLoader, _SourcelessFileLoader, ExtensionFileLoader). This exposes all of importlib's mechanisms that will become public on the sys module. 2012-04-22 19:58:33 -04:00			`from ._bootstrap import FileFinder`

Issue #14605: Rename _SourcelessFileLoader to SourcelessFileLoader. This time also recreating the Python/importlib.h file to make make happy. See the ticket for details. 2012-04-25 02:31:37 +02:00			`from ._bootstrap import SourcelessFileLoader`
