* Issue #14646: __import__() now sets __loader__ if need be.Brett Cannon2012-04-271-3/+25
| | | | | | importlib.util.module_for_loader also will set __loader__ along with __package__. This is in conjunction to a forthcoming update to PEP 302 which will make these two attributes required for loaders to set.
* Issue #14605: Use None in sys.path_importer_cache to represent noBrett Cannon2012-04-271-21/+5

* Issue #14605: Stop having implicit entries for sys.meta_path.Brett Cannon2012-04-271-4/+4
| | | | ImportWarning is raised if sys.meta_path is found to be empty.
* Issue #14605: Make explicit the entries on sys.path_hooks that used toBrett Cannon2012-04-261-45/+19
| | | | | | | | | | | | be implicit. Added a warning for when sys.path_hooks is found to be empty. Also changed the meaning of None in sys.path_importer_cache to represent trying sys.path_hooks again (an interpretation of previous semantics). Also added a warning for when None was found. The long-term goal is for None in sys.path_importer_cache to represent the same as imp.NullImporter: no finder found for that sys.path entry.
* Issue #14605 and #14642:Marc-Andre Lemburg2012-04-251-0/+7
| | | | | | Issue a warning in case Python\importlib.h needs to be rebuilt, but there's no Python interpreter around to freeze the bootstrap script.

| | | | | | | | importlib.machinery.(FileFinder, SourceFileLoader, _SourcelessFileLoader, ExtensionFileLoader). This exposes all of importlib's mechanisms that will become public on the sys module.

* Issue #13959: Keep imp.get_magic() in C code, but cache in importlibBrett Cannon2012-04-201-4/+8
| | | | | | for performance. While get_magic() could move to Lib/imp.py, having to support PyImport_GetMagicNumber() would lead to equal, if not more, C code than sticking with the status quo.

* | Issue #14582: Import returns the module returned by a loader insteadBrett Cannon2012-04-151-6/+10
|/ | | | | | | | | | | | of sys.modules when possible. This is being done for two reasons. One is to gain a little bit of performance by skipping an unnecessary dict lookup in sys.modules. But the other (and main) reason is to be a little bit more clear in how things should work from the perspective of import's interactions with loaders. Otherwise loaders can easily forget to return the module even though PEP 302 explicitly states they are expected to return the module they loaded.

* Issue #2377: Make importlib the implementation of __import__().Brett Cannon2012-04-141-6/+29
| | | | | | | importlib._bootstrap is now frozen into Python/importlib.h and stored as _frozen_importlib in sys.modules. Py_Initialize() loads the frozen code along with sys and imp and then uses _frozen_importlib._install() to set builtins.__import__() w/ _frozen_importlib.__import__().
